Search

Fetching recently published research papers is a time consuming and tedious process for young researchers and even for experts. In real time searching papers based on keywords and queries in search engines may not result apt or proper research papers that the user searched for. Because these research papers lack proper links and citations that help to find the most concerned papers. To overcome this problem a hybrid model is proposed with time constraint that combines the Text mining and Recommendation algorithm. The preference of papers and articles are jointly modeled with matrices sharing common dimensions of researchers and papers. The initial process starts with text mining algorithm that matches keywords with the data available in web pages. The post process consists of recommendation algorithms with latent matrix factorization and tensor matrix with similar preferences in a dimensional space. This paper explains the hybrid experimental model that helps users to fetch the most recent and relevant paper in a short period of time

Показана эффективность применения суспензии бактериальной целлюлозы Komagataeibacter (Gluconacetobacter) rhaeticus при реставрации документов на бумаге аэродинамическим способом. Одной из проблем при реставрации документов на бумаге методом восполнения утраченных частей документа является прочность шва между реставрируемым документом и восполняющей частью. Для повышения прочности шва документ по контуру утрат обрабатывают связующими - растворами натриевой соли карбоксиметилцеллюлозы или крахмала. В данном исследовании при реставрации методом аэродинамического формования в качестве связующего была применена суспензия бактериальной целлюлозы Komagataeibacter (Gluconacetobacter) rhaeticus. Для создания прочного соединительного шва между реставрируемым документом и восполняющим волокнистым слоем по контуру утраты документа наносили суспензию бактериальной целлюлозы концентрацией 1,0 ± 0,1% масс., предварительно подготовленную в дезинтеграторе. Применение бактериальной целлюлозы в качестве связующего при аэродинамическом способе реставрации привело к повышению прочности сформованного шва в 1,5-2 раза, по сравнению с применением в качестве связующего растворов крахмала и натриевой соли карбоксиметилцеллюлозы. Искусственное тепло-влажное старение документа после реставрации в течение 12 суток показало, что прочность шва снижается после первых трех суток старения на 32% и затем стабилизируется. Это позволяет прогнозировать хорошую сохранность отреставрированного документа в процессе дальнейшего архивного хранения и пользования. С помощью программного комплекса, предназначенного для исследования памятников письменности путем анализа их цифровых изображений «Vestigium» показано, что рельеф поверхности листов документа после реставрации становится более сглаженным, что снижает возможность глубокого проникновения пыли в структуру листа и повышает срок использования документа. The effectiveness of the bacterial cellulose suspension Komagataeibacter (Gluconacetobacter) rhaeticus in the restoration of documents on paper using the aerodynamic method is shown. One of the problems in document restoration on paper using the method of replacing lost parts of a document is the strength of the seam between the document to be restored and the replacing part. To increase the strength of the seam the document is treated with binders - solutions of sodium salt of carboxymethylcellulose or starch on the contour of the loss. In this study, a suspension of bacterial cellulose Komagataeibacter (Gluconacetobacter) rhaeticus was used as a binder for the restoration by aerodynamic molding. In order to create a strong bonding seam between the restored document and the replenishing fibrous layer, a suspension of bacterial cellulose with a concentration of 1.0 ± 0.1 wt. %, previously prepared in a disintegrator, was applied along the contour of the lost document. The use of bacterial cellulose as a binder in the aerodynamic method of restoration led to an increase in the strength of the formed seam by 1.5-2.0 times compared to the use of starch solutions and sodium salt of carboxymethylcellulose as a binder. Artificial heat-moist aging of the document after restoration for 12 days showed that the suture strength decreased after the first three days of aging by 32% and then stabilized. This makes it possible to predict good preservation of the restored document during further archival storage and use. With the help of «Vestigium» software designed to study the monuments of writing by analyzing their digital images, it is shown that the relief of the document sheets surface after restoration becomes smoother, which reduces the possibility of deep penetration of dust into the sheet structure and increases the life of the document.

Эксперименты, описанные в статье, выполнялись в лабораторных условиях в рамках написания диссератции на соискание ученой степени кандидата технических наук. Актуальность и новизна подтверждена опытными инженерами ведуших компаний-производителей оборудования и передовых технологий в области ЦБП. На процесс сушки полотна бумаги и картона затрачивается наибольшее количество потребляемой на бумаго- и картоноделательных машинах энергии. Однако при этом удаляется незначительное количество влаги из материала, по сравнению с обезвоживаниемна сеточной и прессовой частях. Поэтому для снижения затрат теплоты, а также повышения производительности БДМ представляется целесообразной интенсификация процесса сушки при минимальных затратах энергии и сохранении ключевых технологических показателей выпускаемой продукции. Цель исследования - получение образцов бумаги разной массы одного квадратного метра, изготовленных из производственной сульфатной небеленой хвойной целлюлозы, размолотой в лабораторных условиях на коническом рафинере до различной степени помола с последующим отливом и сушкой при разных температурах. После кондиционирования образцы подвергались измерениям свойств бумаги методами неразрушающего и разрушающего контроля. Анализ влияния температур сушки на деформационно-прочностные и структурно-размерные свойства бумаги позволил выявить закономерности, которые могут быть использованы при дальнейших научных исследованиях, а также непосредственно внедрены в производство. Реконструкции, направленные на снижение потребления энергии, а также оптимизация и тонкая настройка технологических режимов процессов сушки бумажного полотна представляют собой одно из перспективных направлений модернизации технологических потоков и повышения конкурентоспособности отечественных и зарубежных предприятий. Researches described in this article were carried out in laboratory as part of writing PhD thesis in Engineering Science. The importance and novelty have been confirmed by experienced engineers from leading manufacturers of equipment and advanced technologies in the field of pulp and paper industry. The process of drying paper and board consumes the largest amount of energy in paper and board machines. At the same time, it contributes to remove a small amount of moisture from the material, compared to dewatering on the forming and press sections. Therefore, in order to reduce heat costs, as well as increase the productivity of the paper machine, it seems appropriate to intensify the drying process with minimal energy consumption and maintaining the key technological properties of paper. The goal of the study was to get paper samples of different basis weights, made from industrial sulfate unbleached softwood pulp, refined in laboratory on a conical refiner till defined grinding degrees, then forming and followed by drying at different temperatures. Analysis of the drying temperatures on the structural-dimensional and deformation-strength properties of paper made it possible to identify tendencies that can be used in further scientific researches, as well as directly introduce them into production. Rebuilds intended for reducing energy consumption, as well as optimizing and fine-tuning the technological modes of paper drying are one of the promising areas for upgrading production lines and increasing the competitiveness of domestic and foreign enterprises in current times.

Exams are getting digitized all over the world. Basically, meaning that the traditional paper-based tests are being replaced by the certain computer-based tests which have proven to be both more consistent in allocating marks and faster than teacher correcting papers. The traditional exams usually consisted of subjective answers which were not the best way of grading the student’s perception of the subject. Hence, we are developing a computer-based system that will generate MCQ based question that will be better suited to grade students academically. So, Incremental Question Paper Generator (IQPG) is an attempt at developing a software which can implement adaptive evaluation along with generation of questions on its own. The software aims to generate an increasingly difficult or easy in simpler words, it aims to generate a question paper which dynamically changes the difficulty of its questions. Along the same the software generates these questions by learning from a pre-made dataset of questions.

This study investigates the emotional experiences of undergraduate students when taking computer-based compared to traditional paper-based exams. The authors surveyed 144 students and conducted in-depth written interviews with 44 of them to gain a comprehensive understanding of their emotions and experiences. The findings revealed that students generally feel more positive emotions, such as enjoyment, hope, and pride during computer-based exams. Conversely, they experienced less anger, anxiety, and hopelessness compared to paper-based exams. However, they observed no significant differences in feelings of relief and shame between the two exam modes. The interview responses provided valuable insights into the reasons behind these emotions. Students found computer-based testing to be more efficient, user-friendly for language editing, and appreciated the auto-grading features. However, technical concerns were identified as a major challenge in this format. On the other hand, paper-based exams allowed students to avoid technical problems, draft their answers, and express ideas more effectively. Despite these advantages, students reported disliking the lengthiness of the written responses, the difficulty of editing, and the pressure of maintaining legible handwriting. Overall, this study sheds light on the emotional experiences of students in different exam formats, helping educators make informed decisions to optimize testing environments.

A surface profilometry technique was used to characterize the surfaces of paper products. A stylus-contact type profilometer capable of simultaneously generating both surface roughness- and friction-profiles was used. As a stylus for the profilometer, a conical shape whose tip was rounded to have a 0.5 mm curvature radius was designed and successfully employed in both printing & writing (P&W) papers and hygiene papers such as bathroom tissues and kitchen towel. From the profiles, the mean absolute deviation (MAD) from the averages, i.e., R-MAD from the roughness average and F-MAD from the average coefficient of friction, were suggested as the new surface characterization parameters. To elucidate the surface roughness profiles by fractal dimension analysis, the variogram method was applied to get the fractal dimensions of the paper products. Generally, the value of the fractal dimension increased as the surface roughness increased. The surface profilometry technique with the fractal dimension analysis with the variogram method looks promising to gain additional insight on the surface characteristics of paper products.

In an earlier publication (Van Wee & Banister, 2016), we explained that literature review papers (LRP) should explicitly report on the search and selection process of documents included. In this paper, we present two approaches for reporting the methodology for doing this: a basic approach and a reasoned approach. The basic approach includes reporting databases(s), keywords, search strings, snowballing, the selection of documents, presenting an overview of documents included and reporting additional selection criteria (if applicable). The reasoned approach adds to the basic approach (what was done) by explicitly explaining the motivation for choices and showing the selection process graphically (why it was done). The two approaches should be seen as options, and not the only alternatives. We recommend that authors of LRPs depart from these approaches and modify them where appropriate. The important lesson is that authors should be explicit about the approach adopted, as this enables the reader to understand the thinking behind the LRP and the conclusions drawn.

Introduction: Summative assessments play a major role in shaping the student’s learning. There is little literature available on validity of summative assessment question papers in Forensic Medicine & Toxicology. This study analyses 30 question papers from 6 reputed universities for content validity. Methods: A retrospective cross-sectional record-based observational study was conducted where 30 university summative question papers in Forensic Medicine & Toxicology from 6 universities across India were evaluated for content validity. The learning domain assessed, the type of questions asked, and sampling of the content was compared and presented in the results. Results: From the results of the study, it was noted that 80% weightage was allotted to recall in most papers and only one paper tested for application. 70 to 80% of the marks were allotted to Forensic Pathology leading to disproportionate sampling. Core areas in Toxicology and Medical Jurisprudence were sparsely assessed. Conclusion: The content validity of the summative question papers in Forensic Medicine and Toxicology was unsatisfactory, emphasising the need for evaluation of the clarity and efficacy of the blueprints being used by the universities. Faculty training to motivate and influence a change in the mindset is necessary to bring about a course correction.

As a type of Chinese folk art, jianzhi paper carving expresses not only people's spiritual life, but also their aspirations for a better life. Chinese paper carving art is filled with simple life wisdom and good wishes, and the figurative symbols contain unique artistic value and national traits. However, in today's multifaceted development, the traditional art of paper carving with a thousand years of history is gradually fading away. Traditional folk art represented by paper cutting has also begun to be introduced into new fields, not only in graphic design, but also in installation design of public spaces, showing its rich expressiveness and deep artistic value. This paper will examine the characteristics of traditional national paper carving, highlight cultural differences between Eastern and Western paper carving art, combine traditional folk art of paper carving with modern artistic expressions, analyse symbolic and emotional imagery and explore new ideas for the development and innovation of Chinese national art.

Demand for green environments has stimulated research on the migration from conventional to renewable energy sources. In the case of combustible energy for domestic applications, briquettes produced from biomass have proven to be a good replacement for wood fuel. In this study, investigation on the performance analysis and optimization of mix ratio of briquettes produced from sugarcane bagasse using composite binders (waste paper and clay) was carried out. Box-Behnken Design feature of the Design Expert software was employed for the optimization of the briquettes mix ratio. Briquettes were produced from sugarcane bagasse based on the optimum conditions of 9.12% clay, 12.57% waste paper, 78.31% proportion of sugarcane bagasse and 5 KN compaction pressure. The produced briquette was found to have a compressive strength of 6.4715 MPa and 0.857 g/min burning rate. The results of the study shows that the experimental values were close to the predicted values with a percentage error of 3.11% for compressive strength and1.79% for burning rate which confirms the validity and adequacy of the predicted models.

Examination is one of the important elements in measuring the student achievement and to determine whether the course learning outcome is achieved or not. The best exam paper is the paper that can evaluate the students’ achievement and thus satisfy the course learning outcome. The purpose of this study is to compare the examination papers and identify whether the course learning outcome is achieved or not based on the performance of students in the examinations. The sample is stratified according to year 1 until 4 and according to the program. The students are selected from three academic years 2015/2016, 2016/2017 and 2017/2018. The data is obtained from the marks of their mid-semester and final exams. Difficulty and discrimination indices is evaluated for each item in the exam paper. The research findings found that the ideal question for the mid-semester exam is from the session 2017/2018 with difficulty and discrimination indices range from 0.4 to 0.8. While the ideal question for final semester exam is from session 2016/2017 with difficulty index in range 0.4-0.6 and higher discrimination index as compared to other sessions. As a result, the student performance for 2017/2018 session has increased significantly in the overall assessment with 13.0% obtained grade A compared to 11.1% in 2016/2017 and only 4.9% in 2015/2016. The failure rate has also reduced at only 11.4% in 2017/2018 compared to 32.1% in 2015/2016 and 11.9% in 2016/2017.

This study was designed to examine the feasibility of recycling cassava effluent, sawdust, and unused paper products to enhance their utilization for beneficial purpose. Waste newspaper paste (WNP), Waste writing – paper paste (WWP), and Waste carton paper paste (WCP) were prepared and then used separately to similarly fabricate composite panels with Sawdust particle (SDP) proportioned at 0%, 25%, 50%, 75%, and 100% by weight. The binder used was cassava starch slurry prepared from the effluent. Bulk density, water absorption, thermal conductivity, specific heat capacity, thermal diffusivity, nailability, and flexural strength were determined for the developed samples. From the results obtained, the samples were found to be light-weight and their thermal insulation performance improved with increasing proportions of the SDP. Though samples containing the WCP exhibited the best satisfactory performance, it was found that all the studied samples could perform more effectively and efficiently as ceilings compared to some of those reported in the literature. From scientific-economic viewpoint, valorizing the above-mentioned wastes as described in this paper could help to protect the environment and also yield value-added insulation ceilings for enhancement of sustainable building construction especially in tropical areas.

Introduction The barrier properties of paper-based packaging may not be sufficient for long-term storage to ensure the quality and taste of packaged food products. All this requires researching the technological features and developing a combined packaging material in which the base paper is combined with polymer materials or a metallized coating is applied to its surface. Results and discussion Food products are very sensitive to the influence of external factors, so the barrier properties of paper-based packaging become insufficient for long-term storage to ensure the quality of food products and their taste properties. All this requires the development and mastery of the production of modern barrier combined packaging materials and conducting research on the development of requirements for base paper in order to obtain combined, namely: metallized packaging materials. As research results have shown, base paper should be characterized by high resistance to mechanical influences in the process of processing, as well as exploitation of the finished material. It should have a surface that provides optimal interaction with the foil, have high barrier and protective properties. In the process of carrying out research on the creation of a new combined package, the requirements for the metallized material and the quality of the base paper were determined. The index of smoothness of the surface of the base paper should not be lower than 150 s, and its moisture content should not exceed 4%, because its higher values, as experiments have shown, do not allow creating the necessary rarefaction in the chamber for metallization and ensuring the uniformity of metal application. In the case of spraying aluminum with increased residual humidity of the paper, intensive oxidation processes take place, which negatively affect the quality of the coating, its protective properties and the strength of adhesion (adhesion) to the surface of the substrate. As a result of the research, graphical dependences of the electrical resistance and opacity of the metallized material on the thickness of the coating were also obtained, which plays an important role in improving the protective, barrier and other properties of the packaging. Experimental data were also obtained that illustrate the influence of the speed of rewinding and the smoothness of the surface of the base paper in the process of metallization in a vacuum on the indicator of electrical resistance, which is an indirect characteristic of the thickness of the metallized coating of the material. The conducted studies of the new combined metallized packaging material also showed that the coating contributes to the improvement of the protective properties of the material and the tightness of the packaging, namely: reducing gas permeability, weakening the effect of optical radiation on products, increasing the opacity and smoothness of the surface. Conclusions New packaging materials created in the course of research - paper with a metallized coating can be used in packaging processes.

This paper investigates the behaviour of partial discharge (PD) in transformer insulation paper based on the Finite Element Method (FEM). The three-dimensional (3D) FEM model consists of conductor and insulation paper, representing part of a transformer’s high voltage winding. The conductor’s width, height, and length used in this study were 2.4 mm, 11.5 mm, and 16 mm. An insulation paper thickness of 1 mm was modelled around the conductor. An internal cavity with a diameter of 0.5 mm cavity was introduced within the insulation paper. This study introduced two locations of the spherical cavities at the centre and left corner of the insulation paper: Location 1 (L1) and Location 2 (L2). An AC voltage of 33 kV, 50 Hz, was applied to the conductor while the bottom of the insulation paper was grounded. The model was used to study the electric field distribution within the insulation paper and its effect on PD current and charge magnitude. The influence of cavity location on the charge magnitude was also examined. It is found that the electric field distribution is influenced by the conductor configuration as well as the location of the cavity. The electric field in the cavity is the highest at L1 compared to L2. The first PD occurs faster for the cavity with a high electric field. Due to the PD occurrence at the same inception field, the real PD current and charge magnitude is similar at different locations. The apparent PD current and charge magnitude induced at the ground electrode is slightly higher at L1 than at L2.

Background: Development of computer-based software, termed electronic glucose management system (eGMS), offers an alternative strategy to manage diabetic ketoacidosis (DKA) compared with institution-specific paper protocols by integrating glucose and insulin titration into the electronic medical record. Objective: To evaluate the safety and efficacy of eGMS versus a paper-based DKA protocol in an urban academic medical center. Methods: Single-center, retrospective analysis of patients admitted for DKA. The primary objective of this study was the time to transition from intravenous to subcutaneous insulin after resolution of DKA pre- and post-eGMS implementation. Secondary outcomes included incidence of hypoglycemia while on an insulin infusion, intensive care unit (ICU) length of stay, and total hospital length of stay. Results: Time to DKA resolution was similar in both groups with a median time of 8.6 versus 8.8 hours in the paper-based (n = 133) and eGMS groups (n = 84), respectively ( P = 0.43). Hypoglycemia occurred more frequently in the paper-based group compared with eGMS during insulin infusion (14 vs 3 patients, P = 0.06). The median ICU (36.5 vs 41.4 hours; P = 0.05) and hospital length of stay (67.9 vs 77.8 hours; P = 0.05) were shorter in the paper-based group compared with the eGMS group. Conclusion and Relevance: Similar rates of DKA resolution were seen for patients managed with a paper-based protocol compared with eGMS. Patients in the paper-based protocol had a shorter ICU and hospital length of stay; however, eGMS had improved clinically relevant safety outcomes.

Further, to obtain the students’ perceptions, the researcher collects the data through interviews. The result indicates that most students show positive perceptiveness in utilizing Paper-mode Quizizz for formative assessment in teaching and learning English. It is stated that Paper-mode Quizizz is easy to use, enjoyable, fun, challenging, and very interesting. The students only show and rotate the answer, and the teacher will scan the code cards to display the real-time results. In addition, this makes students more motivated to have a test using Paper-mode Quizizz. To sum up, Paper-mode Quizizz is an effective-alternative platform to use for formative assessment in English teaching and learning.

Cognitive bias, especially confirmation bias and motivated reasoning, poses a significant challenge to argumentative writing genres, including the persuasive essay. To address this challenge, I introduce the complexity paper. Rather than attempting to convince the reader of a particular position on an issue as with a persuasive essay, the goal of a complexity paper is to convince the reader that the issue under discussion is difficult to resolve. This altered motivational structure encourages the writer to engage in perspective taking, thereby addressing confirmation bias and motivated reasoning. I outline a three-part structure of the complexity paper using the example of physician-assisted suicide with the goal to help university instructors implement this genre into their courses. I recommend incorporating a complexity paper into a writing scaffold structure that precedes an argumentative paper.

China adopted a “Zero-COVID” policy for nearly three years, making Chinese healthcare workers constantly involved in COVID-19-related work. However, little is known about how involvement in COVID-19-related work shaped Chinese nurses’ burnout. This study explores how nurses’ job demands and job resources are associated with their burnout by considering high and low frequent involvements in COVID-19-related work in China. This study employed a cross-sessional design. Guided by Job Demands-Resources (JDR) model, we developed hypotheses and tested them using regression analysis with a sample of 336 nurses working in four public hospitals in Guangdong, China. Overall sample results revealed: 1) frequency of involvement in COVID-19-related work was related to a higher level of workload; 2) nurses’ burnout was positively associated with workload, emotional demands, and work-family conflict, and negatively associated with a relationship with supervisor, remuneration, and independence of work; 3) emotional intelligence mitigated the positive relationship between workload and burnout. Comparison analysis showed significant differences due to the frequency of involvement in COVID-19 work. In the high-frequency group (N = 108), 1) emotional demands were related to a higher level of burnout, and emotional intelligence moderately accentuates the positive relationship between the two variables; 2) remuneration was related to a lower level of burnout; 3) nurses reported higher levels of workload and relationship with the supervisor. In the low-frequency group (N = 147), independence of work was related to a lower level of burnout; We found some evidence that nurses’ job demands and job resources and their associations with burnout differed due to their frequency of involvement in COVID-19-related work. Implications for policy-making and theoretical contribution are discussed.

Purpose: A less computationally intensive methodology is required to digitise paper Electrocardiogram (ECG) records from scanned photographs so that it can be implemented on mobile devices and used in remote places without the necessary hardware or software requirements. Due to numerous degradations inherent in older resting paper ECG recordings, automated digitization of paper ECG records also becomes challenging. Methods: In the proposed method, we present a robust and simple, Level of Binarization (LOB) characteristic curve to binarize paper records. The binarized image is processed using the discontinuous signal correction (DSC) technique and is vertically scanned to extract 1-D ECG signal. Results: The proposed method is tested for paper ECG records having degradations like variable background colour, steep slope, ink evaporation, and folding. The average RMS error and accuracy for 101 test samples, is 0.01 and 98.34 % respectively. The results show that, the LOB-DSC gives better performance when compared to the existing ECG extraction methods. As proposed, the LOB method does not require pre-processing, and the computational complexity is also reduced. Conclusion: An automatic threshold for binarization and estimation of several types of degradations in old ECG records is obtained using the less computationally intensive LOB characteristic curve. This method can be applied in remote locations with low availability of advanced processing devices for ECG signal extraction.

One of the writing skills that must be mastered by intellectuals is writing scientific papers. The Indonesian curriculum covers all language skills, including writing. The curriculum is described in the Competency Standards and Basic Competencies (SK and KD) from elementary to high school levels. This study aims to determine the ability of students in class XII MIA 4 SMA Panca Budi in writing scientific papers that will be useful for continuing their education to the university level. This research was conducted as a solution offer that would guide these students to write using an approach, namely "Process Approach". The results showed a significant increase in the ability to write scientific papers. This is proven by the movement of students' average writing scores from 63.10 during the pre-test, to 73.13 during the test in cycle 1 and increased again to 88.82 in the test in cycle 2. In other words, the process approach has been proven to be able to improve the ability to write scientific papers of students, especially students of grade XII MIA 4 SMA Panca Budi.

This work examines the physical and electrical breakdown characteristics of kenaf paper coated with Polyvinyl Alcohol (PVA) for application in power transformers. The paper was made from kenaf bast fibers using the soda pulping method, whereby the pulps were subjected to 12,000 beating revolutions. PVA with weight percentage concentration up to 6% was introduced to the beaten kenaf through a spin coating approach. The structure of the kenaf paper was examined through Scanning Electron Microscopy (SEM). The physical properties examined were apparent density, Tensile Index (TI), Burst Index (BI), and Tear Index (TeI), while AC breakdown voltage and strength were analyzed for the electrical property. It is found that the beating and external PVA improve the kenaf paper’s apparent density, TI, BI, and AC breakdown strength while the TeI decreases.

Chitosan and chitosan modified carboxymethyl were used to enhance performances of paper packaging. Chitosan 1.0 wt% and chitosan modified carboxymethyl solutions with concentrations of 0.25; 0.5 and 1.0 wt% were manually applied on paper surface using dip coating method. Effects of chitosan coatings on antibacterial properties of the paper were investigated. The antimicrobial activity of chitosan against gram-positive (Staphylococcus aureus) and gram-negative bacteria (Escherichia coli) was found to be enhanced when chitosan and chitosan modified carboxymethyl solution were entrapped within paper. Further paper coated chitosan and chitosan modified carboxymethyl has higher antibacterial activity againt S. aureus rather than E. coli. Keywords: Chitosan carboxymethyl, antibacterial agent, paper packaging

Fold cracking, which reduces the economic feasibility of paper-making, is a localized surface deformation caused by extreme bending stress. Most paper products, such as base paper and coated paper, generate fold cracking during folding processing. To control fold cracking, the mechanical properties of the base paper can be strengthened, and the flexibility of the structure can be increased by controlling the modification in pulp fibers and stock preparation conditions. This study analyzed the changes in the mechanical properties of high-grammage paper in response to the addition of precipitated calcium carbonate (PCC) and cationic starch (C-starch). The application of inorganic filler (PCC) drastically reduced the internal bond strength and tensile strength, causing fold cracking, whereas C-starch increased the bond strength between fibers, which improved the tensile strength, internal bond strength, and elongation. However, when applied independently, fold cracking occurred because of extreme increase or decrease in strength. Therefore, the combined application of C-starch and PCC made it possible to form a paper-based structure with high fold cracking resistance. Moreover, when the fold cracking resistance was excellent, the mechanical properties were balanced without being biased in one direction even under conditions of relatively low mechanical properties.

Background: The incidence of colorectal cancer (CRC) in Asia has kept increasing in the last decade. The morbidity and mortality for CRC can be reduced with early detection; however, mass CRC screening with imaging modalities such as colonoscopy, CT scan, or MRI is unfeasible in developing countries such as Indonesia. Asia Pacific Colorectal Screening (APCS) is utilized to stratify individual CRC risk. Online screening via mobile application is an alternative method to ensure the continuity of community screening without risking COVID-19 transmission. Objective: We conducted a descriptive study to evaluate CRC risk using APCS in two different villages. Methods: This is a cross-sectional study involving 925 and 207 subjects in 2019 and 2020, respectively. The APCS survey in 2019 was done before the COVID-19 pandemic with paper-based questionnaires and direct assessment by door-to-door approach. Meanwhile, the APCS survey in 2020 was done during the COVID-19 pandemic using websites and mobile apps available for Android and iOS. We gathered participants’ characteristics and the APCS score in both groups and tabulated them. Results: In 2019, out of 925 subjects; 472 (51%) have been classified an average risk of CRC, 370 (40%) have been classified as having a moderate risk of CRC, and 83 (9%) have been classified as in high risk of CRC. In 2020, out of 207 subjects; 106 (51.2%) have been classified as the average risk of CRC, 86 (41.5%) have been classified as the moderate risk of CRC, and 15 (7.3%) have been classified as high risk of CRC. Conclusion: Although there was a decrease in the participation of the screening program with mobile applications in the pandemic era compared with paper-based questionnaires before the pandemic era, online screening using APCS in mobile applications is a preferred alternative for an effective screening method in this pandemic and possibly in the future in Indonesia.

研究論文, This study discussed the difficulties encountered by an international student in graduate school when writing research papers in Japanese for the first time and her disposition development. The analysis of interview data revealed that the international graduate student with a performance-oriented goal showed increased anxiety and decreased self-efficacy when writing papers. The student coped with her anxiety in a way that helped her feel relieved and secure, and she changed her goal through self-reflection. Furthermore, the student responded to a decrease in self-efficacy by reflecting on her learning environment, and consequently adopting a sense of responsibility helped her to control her own efficacy. The student developed the dispositions of engagement and openness through writing papers. Thus, to elicit engagement, it is important to build confidence and self-esteem, and the key to achieving these aims is to experience each step of the research process, including mid-term and final presentations, and recognize that she has the approval of those she holds in respect. In addition, the sense of achievement on completing a paper develops a sense of openness, leading to independent study.

Penurunan kasus COVID-19 di Indonesia menandakan status pandemi mulai bertransisi menuju endemik. Endemik COVID-19 bukan mengartikan bahwa virus COVID-19 telah hilang sepenuhnya sehingga masyarakat tetap perlu menjaga pola hidup sehat salah satunya menjaga sanitasi. Penggunaan sabun dirasa kurang praktis sehingga perlu dilakukan inovasi produk sanitasi berupa travelling paper soap berupa sabun kertas yang memudahkan untuk dibawa kemana saja. Tujuan dari pengabdian ini adalah melakukan pendampingan pembuatan travelling paper soap guna meningkatkan sanitasi endemik COVID-19 serta membantu meningkatkan keterampilan dan perokonomian masyarakat di Desa Tanjung Pering Sumatera Selatan. Metode pengabdian masyarakat yang digunakan pada kegiataan ini yaitu berupa praktek, penyuluhan, bimbingan teknis dan pendampingan. Pengabdian dilaksanakan dalam waktu kurang lebih 2 bulan kepada Ibu-Ibu PKK di Desa Tanjung Pering Sumatera Selatan. Sebelum dilakukan pendampingan, diberikan pengantar terkait pentingnya mencuci tangan menggunakan sabun di masa endemik COVID-19 ini. Banyak ibu-ibu PKK yang belum memahami pentingnya penggunaan sabun dan lebih memilih menggunakan handsanitizer yang dirasa praktis untuk dibawa kemana saja. Pembuatan yang dilakukan sederhana sehingga kedepannya ibu-ibu PKK dapat menerapkannya sendiri dirumah dan dapat menjadi wadah usaha baru untuk dikembangkan. Selain itu, produk travelling paper soap yang telah dibuat dapat dimanfaatkan untuk menanggulangi masalah penularan COVID-19 di masa endemik ini. Pemahaman ibu-ibu PKK tentang pentingnya penggunaan sabun meningkat setelah pengabdian ini serta ibu-ibu PKK mendapatkan keterampilan dalam pembuatan produk Travelling Paper Soap.

The paper scrutinizes the role of documents and documentarity in The Rings of Saturn by W. G. Sebald. It primarily focuses on those passages of the novel that represent the excessive amounts of documents via tropes of abundance and proliferation. I argue that the narrator’s meditations upon 20th century history paradoxically connect the overwhelming accumulation of documents to the experience of erasure and destruction; however, certain episodes offer another approach, presenting the collection of masses of documents as an idiosyncratic, poetic practice. In these parts of the text, documents are displayed as “heaps” and “clouds” of paper: I reveal the ways Sebald’s language deprives them of their referential function, calling attention to their materiality.

The goal of this study was to provide useful information for people（including graduate students） who want to write and publish academic psychology papers. To estimate（a） the length of time it will take to complete a paper and（b） the future duration of current academic publishing systems, I applied the delta t argument developed by Gott（1993）. Based on some real-world data on publication statistics and a selective history of publishing systems, I argued that（a）a paper may be completed sooner than the author expects and（b） the older peer review system may coexist with or last longer than recent approaches to academic publishing.

This updated report on image guided radiation therapy (IGRT) is part of a series of consensus-based white papers previously published by the American Society for Radiation Oncology addressing patient safety. Since the first white papers were published, IGRT technology and procedures have progressed significantly such that these procedures are now more commonly used. The use of IGRT has now extended beyond high-precision treatments, such as stereotactic radiosurgery and stereotactic body radiation therapy, and into routine clinical practice for many treatment techniques and anatomic sites. Therefore, quality and patient safety considerations for these techniques remain an important area of focus.The American Society for Radiation Oncology convened an interdisciplinary task force to assess the original IGRT white paper and update content where appropriate. Recommendations were created using a consensus-building methodology, and task force members indicated their level of agreement based on a 5-point Likert scale from "strongly agree" to "strongly disagree." A prespecified threshold of ≥75% of raters who selected "strongly agree" or "agree" indicated consensus.This IGRT white paper builds on the previous version and uses other guidance documents to primarily focus on processes related to quality and safety. IGRT requires an interdisciplinary team-based approach, staffed by appropriately trained specialists, as well as significant personnel resources, specialized technology, and implementation time. A thorough feasibility analysis of resources is required to achieve the clinical and technical goals and should be discussed with all personnel before undertaking new imaging techniques. A comprehensive quality-assurance program must be developed, using established guidance, to ensure IGRT is performed in a safe and effective manner. As IGRT technologies continue to improve or emerge, existing practice guidelines should be reviewed or updated regularly according to the latest American Association of Physicists in Medicine Task Group reports or guidelines. Patient safety in the application of IGRT is everyone's responsibility, and professional organizations, regulators, vendors, and end-users must demonstrate a clear commitment to working together to ensure the highest levels of safety.

This article is part of a series on methods for living guidelines, consolidating practical experiences from developing living guidelines. It focuses on methods for identification, selection, and prioritisation of clinical questions for a living approach to guideline development.Members of the Australian Living Evidence Consortium (ALEC), the National Institute of Health and Care Excellence (NICE) and the US Grading of Recommendations, Assessment, Development and Evaluations (GRADE) Network, convened a working group. All members have expertise and practical experience in the development of living guidelines. We collated methods documents on prioritisation from each organisation's living guidelines, conducted interviews and held working group discussions. We consolidated these to form best-practice principles, which were then edited and agreed on by the working group members.We developed best-practice principles for 1) identification, 2) selection, and 3) prioritisation, of questions for a living approach to guideline development. Several different strategies for undertaking prioritising questions are explored.The paper provides guidance for prioritising questions in living guidelines. Subsequent papers in this series explore consumer involvement, search decisions, and methods decisions, that are appropriate for questions with different priority levels.

Since the early 2000s, Japan has been frequently noted as being the only country among about 20 major countries where the publication of academic papers has stagnated. During this period, there have been major changes especially with regards to the Japanese pharmacy schools, such as the shift to a six-year schooling system and the rapid increase in the number of private pharmacy schools. However, few studies have focused on academic productivity specifically among pharmacy schools. Therefore, this study analyzed the outputs associated with the publication of peer-reviewed scholarly articles in Scopus search engine per faculty member in pharmacy schools nationwide in 2020. Professors, associate professors, and lecturers were considered as faculty members. The average number of papers published per the faculty member was 3.13 for national and public universities and 1.15 for private universities, with a significant difference between these universities. Dividing the pharmacy schools of private universities into schools established after 2003 and schools established before that, the production coefficient of the former was 0.98 and that of the latter was 1.33. Newly established pharmacy schools were thus found to be slightly less productive in terms of published papers than traditional schools. The paper productivity of private university pharmacy schools is stagnant; the increase in the number of private schools that have adopted a six-year schooling system has contributed to large extent to the creation of clinically competent pharmacists, but it has also brought to light concerns related to the decline in basic research capabilities of Japanese pharmaceutical academia.

Background: The Integrated Palliative Care Outcome Scale (IPOS) validly and reliably measures symptoms and concerns of those receiving palliative care. Aim: To determine the equivalence of the paper version with an electronic version of the IPOS (eIPOS). Design: Multicentre randomised crossover trial (NCT03879668) with a within-subject comparison of the two modes (washout period 30 min). Setting/Participants: Convenience sample of specialist inpatient and palliative home care patients aged over 18 years with cancer and non-cancer conditions was recruited. Scores were compared using intraclass correlation coefficients (ICC), Bland-Altman plots and via a mixed-effects analysis of variance. Results: Fifty patients were randomised to complete paper-electronic ( n = 24) and electronic-paper ( n = 26) IPOS with median age 69 years (range 24–95), 56% male, 16% non-cancer. The ICCs showed very high concordance for the total score (ICC 0.99, 95% CI 0.98–1.00), lowest ICCs being observed for symptoms ‘Appetite loss’ and ‘Drowsiness’ (ICC 0.95, 95% CI 0.92–0.97). Nine of seventeen items had ICCs above 0.98, as did all subscales. No statistically significant mode, order, age, and interaction effects were observed for IPOS total score and subscales, except for ‘Communication’ ( Fmode = 5.9, p = 0.019). Fifty-eight percent preferred the electronic version. In the group 75+ years, 53% preferred the paper version. Only three entries in the free-text main problems differed between the versions. Conclusion: The very high equivalence in scores and free text between the IPOS and the eIPOS demonstrates that eIPOS is feasible and reliable in an older palliative population.

The paper examines actual problems concerning administrative responsibility for advertising services in the field of preparation and writing papers provided for by the state scientific certification system In recent years, there has been an increase in the number of organizations engaged in illegal preparation of term (year) papers and theses, research articles and Cand. Sci. dissertations. Unfortunately, as practice shows, territorial bodies of the Federal Antimonopoly Service of the Russian Federation (FAS territorial bodies) do not always identify the elements of the crime in the activities of such organizations.FAS territorial bodies refer to the lack of a high level of experts in the field, difficulties associated with conducting linguistic forensic expertise mandatory for fixing and detecting hidden advertising, the lack of a well-developed mechanism for bringing to administrative responsibility. The authors propose measures necessary to eliminate these problems and improve the work of law enforcement agencies.In particular, the authors are convinced that in a separate letter, the Federal Antimonopoly Service of the Russian Federation should oblige its territorial authorities to identify elements of illegal advertising during their inspections aimed at checking compliance with the Federal Law on Advertising and to bring to administrative responsibility citizens, officials and legal entities advertising services for writing scientific papers. The police bodies, as well as the Federal Tax Service agencies should also be involved in this work, and they should be given the appropriate powers.It is advisable for the Prosecutor General’s Office of the Russian Federation to instruct subordinate prosecutor’s offices of constituent entities, cities, districts to carry out monitoring regarding situations when antimonopoly authorities impose or fail to impose administrative responsibility on citizens, officials and legal entities for advertising services for writing papers provided for by the state system of scientific certification.To identify signs of veiled advertising, it is proposed to use clarifications of the Presidium of the Supreme Arbitration Court of the Russian Federation, according to which courts can take into account information that consumers associate with goods in circulation. In relation to the problem of advertising services for the implementation and writing of scientific papers, antimonopoly authorities can use the data of sociological surveys of students and teachers and the conclusions of linguistic expertise.

Medical postgraduates are the new force of scientific research groups in China. However, the limitation of their English language ability restricts their publication of high-level Science Citation Index (SCI) papers to a large extent. Measures to improve students’ SCI language ability from macro, intermediate and micro aspects were discussed through flipped classroom teaching mode, such as students’ reading papers before class, students’ practicing paper writing after class, and teacher’s making comments in class. The feedback from the questionnaire showed that 96.65% of the students were satisfied with the teaching mode and 93.57% of them had improved their confidence in SCI writing. For the problems mentioned in the feedback, it was suggested that colleges and universities should formulate policies to encourage teachers to engage in medical English teaching, meanwhile teachers should constantly improve their professional quality, so as to help students improve their SCI language ability rapidly.
