In order to narrow the gender gap in the science, technology, engineering, and math (STEM) field, many countries have formulated relevant policy measures. This study summaries policy documents, plans and projects of women's STEM education in different countries, and conducts text content analysis from three aspects, i. e., policy makers, policy elements, and policy implementation and evaluation. Results show that there are three types of policy makers, and each has their own focus. In terms of policy elements, it emphasizes that STEM education for female students in the education stage, as well as the attention to content such as social norms and stereotypes, career development, policy formulation process, and innovation and entrepreneurship has increased. In terms of policy implementation and evaluation, it emphasizes that the implementation of responsible entities and cross departmental cooperation, and focuses on collecting gender data and improving policies with an evidence-based approach. At the same time, this study summarizes the types of implementation cases, and elaborates the foreign projects and measures to improve female STEM education and promote women's participation in STEM fields into five categories, namely, tools and methods, resource orientation, training and communication, platform promotion, and social awareness. To better promote the development of STEM education for women in China, this study summarizes the inspiration and proposes policy suggestions from four aspects, i. e., policy planning, scientific evidence based, project development, and female empowerment.

[Objective] The present paper aimed to understand the diversity of Bombyx batryticatus pathogen in different silkworm areas and the difference in pathogenicity of Beauveria bassiana strains from different sources to silkworm in Yunnan province. (Method) Pathogens were isolated and purified from silkworm samples collected from 9 counties (cities) in Yunnan provincial silkworm rearing areas. The pathogenic species were identified by observing the morphological characteristics and sporulation structure of the strains, combined with the phylogenetic analysis based on ribosomal rDNA-ITS sequences. Furthermore, the effects of B. bassiana from different geographical sources and different spore concentrations on pathogenicity were also determined and analyzed. [Result] The pathogens of muscardine disease in Yunnan silkworm areas belonged to the genera Beauveria, Metarhizium and Cordyceps, among which B. bassiana and Metarhizium rileyi were the main pathogens, accounting for 57.58% and 30.30% respectively. There were certain differences in the pathogenicity of B. bassiana strains from different geographical sources to silkworm larvae. The batryicated silkworm rate of the tested strains was from 72.5% to 95.0%, and the halflethal time (LT50) was between 5.093 and 7. 133 days. Among them, the LL1-1 strain had the highest batryticated silkworm rate (95. 0%), the shortest half-lethal time (5.093 days), and showed the strongest pathogenicity. In contrast, the CB1-2 strain had the lowest batryicated silkworm rate (75.0%), the longest half-lethal time (7.133 days), and showed the weakest pathogenicity. Moreover, with the increase in the concentration of inoculation pathogen, its pathogenicity became stronger, and the batryicated silkworm rate also increased. [Conclusion] The pathogenic species of silkworm muscardine disease in Yunnan province are diverse. B. bassiana and Metarhizium rileyi are the main pathogens, and the pathogenicity of B. bassiana strains from different sources to silkworm are different. The results of the study can provide a reference for the control of muscardine disease and the production of batryticated silkworm. [ABSTRACT FROM AUTHOR]

We found that a mixture of rhombohedral boron monosulfide (r-BS) and graphene nanoplates (GNP) exhibits higher OER activity than commercially available ruthenium oxide. Furthermore, it was shown that when a mixture of r-BS and GNP was further supported on nickel foam, it did not deteriorate even after continuous operation at high output for more than 100 hours. Here, we will introduce these results in detail. [ABSTRACT FROM AUTHOR]

新南向政策下，我國致力於和東南亞國家協會等國的雙邊人才交流與培育，其中馬來西亞與我國交流尤其密切。馬來西亞華文獨立中學雖然致力於師資專業化，但仍有改善空間，因此我國師資培育大學逐步與獨立中學合作，培育馬來西亞師資。然而，我國師資培育系統著重於培育臺灣背景的教師，以符合義務教育的需求。要如何走出地方性，有效協助跨境教師所需要的教師專業知能並確保品質，是一大挑戰。本研究以實徵研究方法探討馬來西亞僑生在我國大學畢業後返回獨中任教，或是曾經接受我國培訓的獨中教師，其教師專業知能的需求情形。本研究以問卷、晤談及焦點座談等方法蒐集資料，並結合重要性—表現分析法與 差距分析進行資料解析，以增加精確性。結果發現，獨中教師的專業成長需求受到環境與時間因素的影響。由於國家情境脈絡不同，馬來西亞當地與跨境學歷的教師需求有所差異；五所學校中有兩所學校的脈絡較為特殊，需求也不相同；而華文教師與其他科目教師不同，對於教學策略的需求較低。在時間與環境（個人、學校環境及國家脈絡）的影響下，教師因特有的脈絡而有不同的專業成長需求。本研究結果可提供各師資培育大學作為課程調整與規劃之參考，以及國家南向教育政策評估的依據。 Under the New Southbound policy, the government of Taiwan is promoting the exchange and cultivation of bilateral talents with the Association of Southeast Asian Nations, in which Malaysia is included. Although Malaysian organizations have been devoted to enhancing the professional development of schoolteachers for years, room for improvement remains, especially for those in Chinese independent secondary schools. Teacher universities in Taiwan are cooperating with these secondary schools by accepting Malaysian students for teacher education, in addition to providing workshops or degree programs to in-service teachers for professional development. However, most teacher education programs in Taiwan are designed for preparing teachers to fulfill compulsory education needs. The challenge is to help those who are willing to become cross-border teachers enhance their teaching profession while maintaining program quality to meet requirements and standards. The aim of this study was to assess the professional development needs of teachers in Chinese independent secondary schools in Malaysia; the study particularly focused on the teachers who have become independent secondary schoolteachers after receiving teacher education in Taiwanese universities and those who received diplomas from other countries but received teacher training from the universities in Taiwan. Importance-Performance Analysis (IPA) and discrepancy analysis were used to perform a needs assessment. IPA has been applied to various areas in education and service industries. Previous studies have proved that combining IPA and discrepancy analysis can improve research validity (Hudson et al., 2004). Therefore, this study applied IPA and discrepancy analysis simultaneously to determine the key factors necessary for more effective professional development.In addition, this study referred to the theoretical framework of teacher professional development in Furner and McCulla (2019) and expanded the environmental factors by adding the influence of national context to explore the cross-border teachers’ professional development needs. Accordingly, two research questions were investigated in this study: (1) What are the differences between the performance and importance (expectation) levels of independent middle school teachers? (2) Under the influence of environmental factors and different time spans in teaching experiences, what are the differences in teachers’ professional development needs? On the basis of previous studies (Day & Gu, 2007; Furner & McCulla, 2019), this study established a two-dimensional framework to analyze the key factors influencing teachers’ professional development. The vertical dimension was related to personal, organizational (school), and social (country) environmental factors. This study explored how and the mechanism through which these three-level environmental factors shape teachers’ professional development needs. The horizontal dimension was related to a teacher’s career stage and focused on how teachers change their professional development needs at each of their career stages. This study utilized surveys, individual interviews, and focus group interviews for data collection. The survey consisted seven pedagogical content knowledge (PCK) attributes and each of them was rated for its importance and performance level by the schoolteachers themselves. A total of 140 responses were returned, and 69 teachers and administrators were interviewed. For data analysis, this study combined IPA and discrepancy analysis to assess needs and determine the improvement priorities. A data-centered diagonal-line model based on previous studies (Abalo et al., 2007; Wyród-Wróbel & Biesok, 2017) was applied. Performance scores were plotted on the X-axis, and importance scores related to the attributes were plotted on the Y-axis. The data center point (means of importance and performance) was selected as the crosshair to construct a two-dimensional plot. A diagonal line was drawn to meet the data center point to divide the traditional IPA graph into six areas. The area above the diagonal lines was considered to represent an improvement-requiring zone and was further divided into three areas: concentrate here, warning, and improvement areas. The area below the diagonal line was the same as that established in the traditional IPA described by Martilla and James (1977); this area was further divided into three areas: low priority, keep up the good work, and possible overkill areas. After conducting the IPA, this study utilized discrepancy analysis to obtain more information on the differences between importance (expectation) and performance by applying a paired-sample t-test to examine whether a significant discrepancy existed. The study results revealed that national context affected teacher learning. Teachers who graduated from local universities in Malaysia revealed less need for teaching strategies compared with those who studied abroad in Taiwan. However, teachers who received cross-border degrees in Taiwan and China displayed similar learning demands, except that the demand for P3 (subject knowledge) was lower for teachers who graduated from universities in Taiwan than for those who graduated from universities in China. Regarding school context, teachers’ professional development needs were different in the case study schools. Teachers at three case study schools (A, B, and E) had similar learning needs, but those at the other two schools (C and D) had different needs. The principal of school D devoted his efforts to engage teachers in school-based professional development. By participating in intra- and inter-disciplinary meetings, teachers cooperated in developing new courses and jointly designed new teaching methods. Therefore, teachers’ demand for teaching strategies was lower than other attributes. School C, located in east Malaysia, had a different culture and school context compared with those in west Malaysia. Many students left school in east Malaysia before graduation to prepare for studying abroad or obtaining jobs. Because students’ learning motivation and learning needs were different from those in west Malaysia, this special school context influenced teachers’ professional development needs in school C. Concerning personal factors, teachers teaching Chinese exhibited lower demands for professional development in teaching strategies than did other subject teachers. Provided with self-study materials, the teachers spent more time trying innovative teaching strategies and teaching students higher-order thinking skills. Therefore, teachers’ learning demands for teaching strategies were relatively low. Teachers’ learning needs at different career stages were determined to be influenced by environmental factors. According to the literature, early career teachers focus on developing classroom management strategies (Furner & McCulla, 2019); however, this study revealed different results. Novice teachers with less than 3 years of teaching experience had a high demand for professional growth in subject knowledge but low demand for class management. According to the interviews, the low demand was because the teachers had participated in several workshops in classroom management during orientation trainings. Experienced teachers (4-7 years of teaching experience), as reported by Furner and McCulla (2019), still concentrate on learning classroom management skills but gradually shift to enhance their instructional strategies. However, this study determined that teachers at a later career stage had a high demand for teaching strategies but no demand for class management. Teachers with more than 21 years of experience exhibited a high demand for teaching strategies, which is similar to the observations by Day and Gu (2007). This study revealed that the three-level (personal, school, and national) environmental factors and different career stages influenced the needs of professional development. Applying IPA and discrepancy analysis to conduct needs assessment can help execute a comprehensive examination of the needs of cross-border teacher learning. One-size-fits-all professional development cannot fulfill teachers’ learning needs. Instead, providing teachers with various professional development programs by considering their academic qualifications, teaching experiences, and school contexts is valuable. The results of the study will be provided to the teacher education programs for universities in Taiwan as well as for the government to assess the implementation of educational policies.

Aiming at the flexible Job-Shop lot-streaming scheduling problem, based on the single minute exchange of die(SMED), this paper established an intermingling scheduling optimization model with objections of minimizing the makespan and the total number of sub-lots, considering the flexibility of sublots splitting and sublots intermingling, automatic changeover and material transportation. Then it proposed an improved two-archive based multi-objective evolutionary algorithm to optimize the objective function. This algorithm adopted the framework of evolutionary algorithm. Based on the framework of evolutionary algorithm, it designed a two-archive based on hypervolume indicator and improved Pareto dominance to balance the convergence and diversity of the population. And according to the characteristics of lot-streaming intermingling problems, it proposed the forward/backward decoding and sub-lot splitting left-shift strategies in the decoding stage. In the stages of neighborhood exploration and global search, it designed adaptive evolution operators for lot splitting and sub-lot intermingling schemes respectively to improve the global search and local search capabilities of the algorithm. Based on different scale examples, it tested the performance of the proposed algorithm and the classical multi-objective algorithms. The experimental results show that the algorithm has obvious advantages in convergence and diversity. [ABSTRACT FROM AUTHOR]

Objective To investigate the relationships between the levels of serum microRNA-155-5p (miR-155-5p) and suppressor of cytokine signaling1（SOCS1) and the degree of lesion and the imbalance of helper T cell 17（Th17）/reg⁃ ulatory T cell (Treg) in oral lichen planus (OLP) patients. Methods Seventy-six OLP patients (observation group) were selected, including 28 non-erosive OLP patients and 48 erosive OLP patients (29 mild to moderate erosive OLP patients, 19 severe erosive OLP patients）, and meanwhile, 50 healthy volunteers (control group) were randomly selected during the same period. Peripheral venous blood of all subjects was collected. Real-time fluorescence quantitative PCR was used to detect serum miR-155-5p and SOCS1 mRNA, and flow cytometry was used to detect the of Th17 ratio and Treg ratio, and to calculate the Th17/Treg. Pearson/Spearman correlation analysis was used to analyze the relationship between serum miR-155-5p level and SOCS1 mRNA level, and their relationships with the ratios of Th17, Treg and Th17/Treg in the peripheral blood. Results Compared with the control group, the serum miR-155-5p level, Th17 ratio and Th17/ Treg in peripheral blood increased, while the serum SOCS1 mRNA level and Treg ratio in peripheral blood decreased in the observation group (all P<0. 05）. In patients with non-erosive, mile-to-moderate erosive and severe erosive OLP, serum miR-155-5p levels, Th17 ratio and Th17/Treg in peripheral blood gradually increased, while serum SOCS1 mRNA level and Treg ratio in peripheral blood gradually decreased (all P<0. 05）. Correlation analysis showed that the serum miR155-5p level was negatively correlated with serum SOCS1 mRNA level in OLP patients (r=–0. 809, P<0. 01）. Serum miR-155-5p level was positively correlated with Th17 ratio and Th17/Treg in peripheral blood (r/rs =0. 819 and 0. 820, both P<0. 05）, and was negatively correlated with Treg ratio (r=–0. 735, P<0. 05）. Serum SOCS1 mRNA level was nega⁃ tively correlated with Th17 ratio and Th17/Treg in peripheral blood (r/rs =–0. 770 and–0. 790, respectively； both P< 0. 05）, and was positively correlated with Treg ratio (r=0. 733, P<0. 05）. Conclusion The serum miR-155-5p level increased and serum SOCS1 mRNA level decreased in OLP patients, and the changes of both levels were closely related to the severity of disease and Th17/Treg imbalance.

Art reading promotion is an innovative aesthetic education practice implemented with the combination of reading promotion and aesthetic education. Libraries have played a crucial role in aesthetic education by providing aesthetic environment, giving access to aesthetic literature and implementing aesthetic activities to cultivate the physical and mental development of the individuals. Due to the lack of research in the art reading promotion field in library, this research aims to analyze the underlying theory and practical models of art reading promotion, bringing up specific advantages for library to carry out art reading promotion activities to fully exert the educational function. With the methodology of literature review, theoretical analysis and case studies, this article looked into the conception of art reading promotion from the origins, analyzed the notable practices of academic libraries, and summarized three stages of aesthetic psychological process as sensory pleasure, emotional resonance and quality improvement. It proposes three practical modes according to aesthetic psychological process with case studies from Zhejiang University of Technology Library. (1) Reading activities with sense of beauty, which refers to the adoption of art in various manifestations generating sensory pleasure to arouse readers' interest and curiosity in reading. (2) Reading activities with beauty appreciation by combining aesthetic values in the themes of reading activities to arouse sympathy among the readers in reading activities. (3) Reading activities with beauty creation by participation of readers in the creation of art far beyond appreciation. It further defines the underlying theory of art reading promotion, which is the interaction of different forms of art with reading activity aims at improving the aesthetic literacy and reading experience simultaneously. It concludes that the current research on art reading promotion is still in exploration and has not yet formed a unified paradigm due to a lack of combination between theories and practices. At the same time, the practices of art reading promotion in libraries faces practical issues such as difficulties in obtaining resources, uneven reader participation, scarcity of professional talents, insufficient activity evaluation and feedback. Therefore, the academic community needs to further enhance the theoretical foundation of art reading aesthetic education and summarize practical experience to extract a paradigm that can be widely applied. Further study is called upon to innovate effective promotion strategies and methods to promote the in-depth development of art reading promotion, so as to meet the demands of the readers and achieve the goal of aesthetic education.

Geopolymer not only possesses the combined excellent properties of organic polymer materials, ceramic materials and cement materials, but also has many advantages such as low production energy consumption and carbon emissions, wide raw material source, and excessive consumption of solid wastes. Therefore, it has rapidly become a research hotspot in the field of inorganic cementitious material in recent years. After introducing the calcium component into geopolymer system, the interaction processes among the main gel phases may become more complicated. Moreover, microstructure and the main performance of geopolymer may be greatly affected. In this paper, we systematically review the research developments in Ca_containing geopolymer, with a particular summary and analysis on the way of introducing calcium component during geopolymer preparing process, as well as the influence rule and action mechanism of calcium component on microstructure and performance (including setting time, compressive strength, solidification/stabilization of heavy metals, resistance to chemical attack, al kali - aggregate reaction, thermal stability, and resistance to efflorescence) of geopolymer. Tt would provide technical reference for performance control and application study of C

Objective To explore the application value of Three-Dimensional rectal cavity ultrasound combined with contrast agent imaging in necrotizing fasciitis of the anal region. Methods Before surgery, standard three-dimensional rectal cavity ultrasound examinations (referred to as the conventional group) and contrast agent imaging examinations (referred to as the imaging group) were conducted for 40 patients clinically diagnosed with anal region necrotizing fasciitis. Separate observations were made for the primary lesion, as well as for the depth and superficial necrosis of the fascia, and injuries to the anal sphincter muscle. Comparative analysis with surgical results was undertaken to assess the diagnostic sensitivity of both the conventional and imaging groups. Results In comparing the conventional group with the imaging group, the rates of primary lesion visibility rose significantly from 70% to 97.5%, deep fascial necrosis visibility increased from 50% to 88.8%, superficial fascia visibility improved from 70% to 100%, and the visibility of anal sphincter muscle injury escalated from 62.5% to 97.2%, all demonstrating statistical significance at P < 0.05. Conclusions Three-dimensional rectal cavity ultrasound combined with contrast agent imaging exhibits significantly enhanced accuracy in identifying primary lesions associated with perianal necrotizing fasciitis, as well as the necrosis affecting deep and superficial fascia, in contrast to conventional three-dimensional rectal cavity ultrasound. This advancement offers more precise guidance for clinicians in devising surgical plans, thereby augmenting the success rate of surgical interventions. [ABSTRACT FROM AUTHOR]

Objective To observe the clinical efficacy of acupuncture at Front Mu point in the treatment of ulcerative colitis. Methods Sixty patients with ulcerative colitis treated at the Traditional Chinese Medicine Hospital in Kunming from August 2022 to June 2023 were collected. Using a random number table method, 30 cases were assigned to each of the control group and the combined group. The treatment method involved administering oral mesalazine to the control group for a continuous period of 8 weeks, while the combined group received both oral mesalazine and acupuncture at front Mu points. The clinical efficacy, colonoscopy results score (Baron score), and colonic mucosal healing score (Geboes) before and after treatment were compared. Follow-up was conducted at 3 months to calculate the recurrence rate in the combination and control groups. Results The total effective rate in the combination group was higher than that in the control group (P < 0.05), with rates of 93.33% and 67.67%, respectively. After treatment, the disease activity index, Baron score, and Geboes score decreased compared to before treatment (P<0.05), and the combination group had a lower disease activity index, Baron score, and Geboes score than the control group after treatment (P<0.05). Comparing the recurrence rates at 3 months posttreatment, the combination group was lower than the control group. Conclusion Acupuncture at Front Mu Point can significantly improve the clinical symptoms of ulcerative colitis, reduce the recurrence rate compared to patients in the control group, and is safe and reliable without serious adverse reactions.

Road edge detection is an important part of the environment perception of autonomous vehicles. Effectively extraction road edge information from point cloud data is beneficial for target detection and drivable area detection. A solution was proposed to address the issue of point cloud road edge detection, taking into account the interference of road participants such as vehicles in road edge detection. Firstly, a ground point cloud segmentation algorithm was used to divide the original point cloud into ground and non-ground points. Secondly, based on the intrinsic characteristics of vehicles and other road participants, a point cloud clustering algorithm was employed to cluster the points and filter out cloud non-ground points that meet the characteristics of vehicles and road participants. Thirdly, considering that road edge point clouds can effectively occlude the line connecting the laser emission center point with non-road edge points in the two-dimensional plane, the road edge point cloud was extracted. Finally, the random sample consensus(RANSAC) algorithm was used to perform polynomial fitting on the road edge point cloud, and an extended Kalman filter was utilized to track the road edge. Experimental results demonstrate that the proposed point cloud road edge detection algorithm can eliminate the interference of vehicles and other road participants on road edge detection, while satisfying real-time and robustness requirements for practical vehicle applications.
