Ensuring sufficient mechanical performance while enabling lightweight design is critical for utilizing paper sandwich panels in the furniture industry. To design lightweight sandwich panels that balance mechanical properties and cost, this study developed a circular core paper sandwich panel (CCPSP) and investigated its structural efficiency using multi-objective optimization. The response surface method (RSM) based on Box–Behnken design was utilized to establish mathematical models relating the paper tube spacing, inner diameter, and height to the out-of-plane compressive strength, density, and cost. The resulting models effectively revealed the coupled effects of the parameters on the responses. Subsequently, the models were optimized using the non-dominated sorting genetic algorithm II (NSGA-II) to find the Pareto optimal trade-offs between maximizing compressive strength while minimizing its density and cost. The optimization solution resulted in an optimal set of paper tube geometries that maximized the structural efficiency of CCPSP. Overall, lower tube height conferred superior structural efficiency, while tube spacing and diameter were constrained. The results highlight the potential of CCPSP as an efficient and sustainable material for furniture manufacturing, enabled by multi-objective optimization of its structure. [ABSTRACT FROM AUTHOR]

This paper presents manufacture and testing of paper boards made from recycled paper pulp. The aim was to create material for creating paper boards which could be used in furniture design with various shapes. The used types of pulp were deinked pulp (DIP) and old corrugated cardboards (OCC). Several test pieces - paper boards were made with different combinations of materials and its mechanical and physical properties were tested. The used glue for each material was urea formaldehyde glue and starch in combination with glucose. The tests which were done were determination of density and density profile (EN 323:2005), moisture content (EN 322:2005), modulus of elasticity in bending and bending strength (EN 310:1993), thickness swelling and water absorption (EN317:2005), internal bond (EN 319:2005) and screw withdrawal resistance (EN 320:2011). The aim was to create material for creating boards which could be used in furniture design with various shapes. The result of this paper shows possible material combinations which could be used for furniture parts. Paper boards will be used for table top of side table in following steps.

Melamine-impregnated paper decorated medium-density fiberboard (MIPMDF) is the main board used for wooden furniture materials in China, and the formaldehyde released from the board and furniture products is harmful to human beings and is a wide concern. This paper aimed to pay attention to the formaldehyde emission of MIP-MDF and its furniture products. This study utilized a 1 m³climatic chamber to measure the formaldehyde emission of MIP-MDF and nightstand made of MIP-MDF in relation to the time and load factors. According to the results, in the 2 to 24 h stage, the emission of formaldehyde in the nightstand made of MIPMDF materials changed significantly, and the overall trend showed a changing trend of first increasing and then declining. The formaldehyde emission of MIP-MDF stabilized after 40 h, while the formaldehyde emission of the nightstand stabilized after 60 h. As time passed, the formaldehyde emission changes of MIP-MDF and nightstand were almost the same. The formaldehyde emission of MIP-MDF and nightstand has a specific positive correlation with the carrying load. With increased carrying loads, the formaldehyde emission tends to increase, but the degree of influence gradually decreases with the addition of the carrying loads. [ABSTRACT FROM AUTHOR]

This paper reports the findings of a case study that examined the importance of flexible learning spaces and student-centred pedagogies for facilitating effective teaching and learning in schools. By exploring the arrangement of learning spaces at the school level, the study compared a case school in Germany with the Future Classroom Lab Model. Data collection involved observations, photographs and video recordings, which were analysed through content analysis. The article demonstrates the alignment of pedagogies with seating arrangements and physical learning spaces by defining the pedagogy employed in a specific course and providing sample course activities. This paper offers suggestions for redesigning and implementing active learning classrooms, emphasising the need to increase flexible learning spaces in schools to enable student engagement with content through student-centred pedagogies. The case study findings underscore the significance of conducting assessments on classroom redesign initiatives.

This paper explores the role of material design as a form of institutional power within contemporary school settings. Drawing on concepts of "coercive design" and "hostile architecture" from design studies, the paper examines three "innovative" designs for classroom chairs -- relatively mundane but integral elements of the regulation and disciplining of school space. It is argued that the design intentions of these material objects reveal a number of constrained, conservative intentions to maintain the traditional ordered notion of the classroom as a place where students stay in their seats and engage in work. Tellingly, however, this corporeal manipulation and moderation is now couched in claims around desirable physiological and cognitive conditions for learning -- with students' bodies seen as objects to arrange and constrain in ways deemed conducive for learning. The paper problematises this de-socialised view of classrooms, alongside the underpinning sense of design solutionism and (mis)appropriation of "learning science" by product designers to justify their products' capacities to somehow cause learning to take place.

Storage systems for oversized works of art on paper are examined regarding object protection, user satisfaction and sustainability by way of a life cycle assessment of furniture materials/construction features and a survey of about 100 institutions worldwide on their experience with oversize storage. General recommendations are derived and a simple checklist is developed to facilitate oversize purchase by museum professionals.

Gibson poses a more serious challenge to the one-dimensional view of Chinese workers as "cheap labour" or a "coolie class" threatening "White workers" (see chapter three, "Workers"). In I Made in Chinatown i , Peter Gibson sets out how the history of Chinese furniture-makers and factories in Sydney and Melbourne subverted the White Australia Policy and the racist logic that underpinned it.

It is seen that studies on learning spaces in higher education institutions are very few in the literature. However, spaces have the power to affect behaviors and interactions with others. This study aims to determine the wishes of university students regarding the physical environment. For this purpose, it is planned to determine the missing things in the existing physical environment according to the "wish poems" of undergraduate students and their related wishes. Accordingly, the sample of the study consisted of 211 participants among the students of the faculty of education at a state university. In the study, for the purpose of revealing the views of the undergraduate students on the physical environment of their school, they were given a semi-structure, open-ended question format as "I wish there were … in my classroom/faculty/campus" and asked to write down 3 wishes regarding the physical environment. The obtained data were analyzed by using the content analysis method. In the study, different numbers of conceptual categories were reached under each sub-title with the method of coding and imaging. At the end of the study, 578 clear responses were obtained, and after examination, these responses were gathered under 35 conceptual categories in total. The categories about which the students had the most wishes were related to the furniture and equipment in their classrooms (f=51, 26.2%), social (f=33, 18.5%) and scientific (f=32, 17.9%) areas at the faculty and green spaces at the campus (f=61, 29.6%). Consequently, as pioneers of social and scientific change, it is important for universities to reevaluate their existing physical facilities based on the wishes of students in terms of feeding their innovative instincts.

Abstract: In this paper, conventional lightweight paper panels and paper tubes are analysed with respect to their suitability as furniture materials. In order to meet the growing demand of furniture industries to build light furniture, these two materials were tested and found to be suitable for creating very light constructions. Furthermore, increasing consumer demand to include sustainable materials in furniture-making is met by these two products. Joints between the two materials were developed and evaluated. It could be determined that specific adaptations are necessary in order to use paper materials for building furniture. The results of this study are a useful basis for developing construction principles between similar materials with other dimensions, e.g., for architecture. [Copyright &y& Elsevier]

The University of Westminster is undertaking a major classroom refurbishment program that is linked to a new approach to staff development in mobile learning. Feedback obtained from academic staff and students previously highlighted how classrooms should be changed so as to promote more active forms of curriculum delivery. Both technology and classroom furniture were considered significant enablers for effective in-class delivery, with the simplicity of the former and flexibility of the latter identified as key. To date nearly 70 classrooms have been re-designed and the impact of the changes on both staff and students has been assessed. Generally, the feedback has been positive with high praise for the easy to use technology solutions provided and the adaptability of the furniture. In addition, the significance of 'getting right' basic features in new classrooms (lighting, acoustics for example) was frequently cited by staff and students. This paper will highlight the features of new classrooms that students and staff have indicated they feel are most significant for their learning and teaching experiences. The paper will also assess the extent to which the new classrooms have been successful through analyzing the impact of both new technology and furniture arrangements on approaches to curriculum delivery. In addition, staff views on the utility of the new staff development approach will be discussed.

The current knowledge of the effects of the physical environment on learners' behaviour in collaborative problem-solving tasks is underexplored. This paper aims to critically examine the potential of multimodal learning analytics, using new data sets, in studying how the shapes of shared tables affect the learners' behaviour when collaborating in terms of patterns of participation and indicators related to physical social interactions. The research presented in this paper investigates this question considering the potential interplay with contextual aspects (level of education) and learning design decisions (group size). Three dependent variables (distance between students, range of movement and level of participation) are tested using quantitative and qualitative analyses of data collected using a motion capture system and video recordings. Results show that the use of round tables (vs rectangular tables) leads to higher levels of on-task participation in the case of elementary school students. For university students, different table shapes seem to have a limited impact on their levels of participation in collaborative problem solving. The analysis shows significant differences regarding the relationship between group size and the distance between students, but there is no substantial evidence that group size affects the level of participation. The findings support previous research highlighting the importance of studying the role of the physical environment as an element of learning design and the potential of multimodal learning analytics in approaching these studies.

This paper presents results of a focus group that gathered data from principals of several public schools in Catalonia regarding the educational impact of Industry 4.0 technologies. Conclusions and recommendations are drawn from qualitative analysis with a view to improving smart classrooms via educational innovation. Results show that the schools see development and implementation of technology leveraging Industry 4.0 as necessary for future classrooms, always based on knowledge and pedagogical principles. Furniture, lighting, acoustics, and air quality are parameters that need to be adjusted in a smart classroom. Technologies such as internet of things, artificial intelligence, and big data make it possible to automate these adjustments, with a risk that the economic cost of such developments could create a gap between schools. Further research in other contexts or countries could report slightly different results. Nevertheless, this paper offers a qualified perspective from school principals about what industry should work on in order to develop smart classrooms, and why.

In the process of the “green revolution”, individuals have realized the importance of recycling waste materials. However, with ongoing individual changes in lifestyle, the huge resource of discarded wooden furniture is still considerably underutilized. This paper aims to provide new ideas for the recycling of discarded wooden furniture and to create added value to used furniture. Based on the summarization of existing recycling technology and methods, the diversified innovation and reuse of discarded wooden furniture integrating the current aesthetic and demand of people from multiple aspects are analyzed for the purpose of revealing the hidden value of waste materials. Waste recycling is of great importance to the country and enterprises in line with the concept of circular economy. For the sake of further excavating the hidden value of discarded wooden furniture products, the additional in-depth research in optimizing and upgrading green production and manufacturing in furniture industry is called for in the paper.

Taiwan's vocational wood-furniture schools still focus only on the traditional manual training strategy, and so students' knowledge of the furniture-manufacturing process is fragmented. Moreover, they possess limited manual skills without learning the workflows and strategies of furniture production, which is inadequate for satisfying the direct work demands of the furniture industry overseas. In response, through virtual reality (VR) technology, this study employed simulations of the furniture production lines in a large Vietnamese furniture-manufacturing factory, enabling students to experience and observe the manufacturing process of furniture production through VR to overcome the limitations in the present teaching environment. In doing so, we recruited 29 freshmen majoring in a furniture-and-woodworking program and divided them into an experimental group (N=15) and a control group (N=14). They were trained with actual furniture production-process cases according to the furniture mass-production process, including paper-based tests, equipment configuration re-draws and production planning table writing. The results showed that the students in the experimental VR-training group had superior judgment concerning the concept of batch furniture production line. This indicates that applying VR technology to the vocational training of batch furniture production effectively enhanced the students' familiarity of the fast and dynamic production situation of furniture production lines.

Faculty in higher education are challenged to change their instructional approaches in outmoded, stagnant learning spaces to meet the needs of 21st century learners. Traditional learning spaces on most college campuses consist of locked, rowed seating and desks designed to maximize room capacity and accommodate large numbers of students. The physical constraints of these spaces often limit the use of more innovative teaching methods that allow students to assume greater ownership of their learning. For more active, student-centered learning to occur, greater mobility in the physical learning space may be necessary to allow for improved connection, collaboration, interest, and engagement. In this paper, we share experiences in forging a public-private partnership to transform a 46-seat computer lab into a 32-seat active learning center (ALC) in which mobility is a signature feature. Upon using the ALC for the first time, options for space and furniture configuration allowed instructors to create, and re-create, work groups to facilitate student collaboration while digital technology and active learning tools allowed students to share information easily and often. Most students rated their experiences in the ALC favorably, though not all participants embraced the active learning approach and instructional space with immediacy. Original research would help to understand students' experiences and isolate the effects of space on student learning and engagement. Our successes and challenges in building and using the ALC may be used to meaningfully inform other public-private partnerships in higher education to transform teaching and learning through active instructional design approaches.

In the spring of 2011, a teacher allowed his fourth and fifth grade students to draw and write on their classroom tables. What began as a few names eventually turned into a series of frenetic marks that completely covered the tabletops. Over the course of two years, new groups of students brought with them another cycle of marking that evolved in the form of notations, designs, and even carvings. The teacher documented this process over the years collecting data in the form of digital photographs, video clips, email communiqués, and teacher journal entries. This paper presents an analysis of the data, a discussion on the effects of allowing general elementary classroom students a significant degree of creative agency, and the pedagogical impacts of that agency.

Educational frameworks mandate schools to adopt, design and implement strategies that support inclusive education. Despite the inclusive education policy, disability remains a major course of exclusion in learning institutions. The paper discusses the impact of school strategies in overcoming physical barriers that hinder the implementation of inclusive education. The actual sample constituted 151 respondents. The data were collected using questionnaires to identify views from 100 teachers teaching learners with disabilities, interviews from 11 learners with disabilities to discuss personal experiences on physical barriers and 5 focus groups discussions with non-disabled learners learning in the same classroom with learners with disabilities. The study was guided by Social Model of Disability and adopted a mixed method research design. Quantitative data were analyzed using inferential statistics. The ANOVA and t-test were done to test the study hypotheses. Qualitative data were organized by developing codes, then categorized into themes and presented in a narrative form. Linear regression was carried out to check the linear relationships between the variables. The study established the school strategies were not anchored in overcoming physical barriers that hindered the implementation of inclusive education, with various challenges affecting the strategies. For this reason, learners with disabilities have to adjust to get the needed education or drop out of school. Therefore, the study concluded that ineffective school strategies contributed to lack of overcoming physical barriers and this negatively impacted the implementation of inclusive education in schools. School transformation founded on clear inclusive education vision and philosophy, policies and inclusive strategies are necessary to overcome physical barriers hindering the implementation of inclusive education.

This paper presents the ergonomic aspects in designing and prototyping of desks cum chairs used in elementary schools. The procedures adopted for the assessment included: the study of existing school furniture, design analysis and development of prototypes. The design approach proposed a series of adjustable desks and chairs developed in terms of ergonomic concepts. In the development stage, the production cost, ease of management, installation and storage were the important factors undertaken. A questionnaire based subjective comfort evaluation survey was carried out on the developed prototypes and the results showed good response and satisfaction levels up to an overall 94%. The details on the ergonomically designed prototype, its development process and customer satisfaction survey have been elaborated in this paper.

Purpose: The purpose of this paper is to share lessons already learned and work currently in progress from one higher education institution's experiences of developing several flexible and technology-enhanced active learning spaces. It further proposes that the potential of such spaces can be more fully realised through the enactment of programmes of digital literacy development amongst their users. Design/methodology/approach: In identifying a convergence of profound challenges facing higher education and proposing that innovations in physical learning spaces are one approach to addressing such challenges, the paper examines a number of institutional policies and initiatives for rethinking and redesigning several physical classroom environments. It sets internal findings and position statements amidst a broader context of relevant field literature. Findings: The paper provides insights from several years of experience in higher education learning space development, including the benefits of iterative experimentation, the consultative role of a multi-stakeholder specialist group, the challenges of balancing pedagogic need with often conflicting institutional requirements and the value of varied programmes of staff development. Originality/value: This paper's insights will be of value to individuals and institutions engaged in reconsidering their provision of physical classroom spaces in higher education and to those promoting the effective use of learning spaces in the digital university.

Flexible classrooms are designed to support active learning through movable tables and chairs that can be rearranged into different layouts and through technology such as wall-mounted monitors and whiteboards. This paper investigates how instructors experienced with active learning use the furniture and technology of a flexible classroom to facilitate active learning. We present a case study of one flexible classroom across courses at different levels of the engineering curriculum, analysing how the instructors used the classroom to implement nine strategies for facilitating active learning. Our findings provide many examples of how the flexible classroom allowed instructors to easily walk around the room and interact with students in a way that better facilitated active learning. The flexible classroom also supported the instructors in developing a routine for active learning and designing activities to better engage students. We conclude by describing evidence-based recommendations for flexible classroom professional development informed by our analyses.

This paper examines the effect of the architectural layout of two classrooms (one flexible and one less-flexible) on Teaching Assistants' (TAs) movement and interactions with students. Four TAs from a first-year undergraduate introductory course were chosen for the two studies. In study 1, the TAs taught the same lesson twice to two groups of students on the same day but in different classrooms, thereby controlling for content differences. Study 2 investigated the impacts that flexible and non-flexible spaces have on the same cohort of students, as the TAs continued to teach the same students but the students switched classrooms for the second half of the course, thereby controlling for differences in student participants. From the video analyses, there was a clear difference in how the TAs moved in the classroom and the interactions they had with students. Both TAs and students reported in surveys that there was a difference in their movement in the respective rooms that had an impact on their teaching and learning quality. This finding starts the conversation on how space can affect TAs, in order for TAs to consider how their movement is affected by classroom configurations, and how this change in movement can affect teaching strategies and impact their students' learning

This paper uses shape grammar to conduct strategic research and innovative translation of existing wooden furniture designs. A traditional Chinese Ming-style recessed-leg table was used as an example to demonstrate its feasibility. The paper applies biological DNA genetic information to furniture products, and combines shape grammar to evolve and mutate them, thereby creating new forms of wooden furniture that maintain the original genes. A DNA gene pool of recessed-leg table was constructed, and an architectural queti replacement pool was constructed based on the rules of shape grammar as backup for subsequent experiments to replace part of the designed genes of the recessed-leg table. Shape grammar was used to deduce the recessed-leg table and generate three plans. A consumer questionnaire was established through the semantic differential method. After evaluating these three design plans, an optimal plan that meets market demand was selected, and modeling, rendering, and concept elaboration were performed. Finally, the paper takes Ming-style recessed-leg table as an example to demonstrate that it is effective and feasible to use shape grammar to guide the design and research of domestic wooden furniture.

Contribution: This paper presents evidence demonstrating ways in which flexible classrooms (which have movable tables and chairs that can be rearranged into different layouts) afford active learning. It highlights the quantitative increase in active learning that occurs for one instructor and discusses how the affordances of the flexible classroom support qualitatively better instructor-student and student-peer interaction during active learning. Background: Research has shown that students benefit from active learning, but instructors still perceive many barriers to implementing it. Flexible classrooms may reduce some of these barriers, and their affordances may promote better student engagement and allow instructors to use more active learning than traditional lecture-style classrooms do. Research Questions: What are the differences in the amount of active learning used by an instructor between flexible classrooms and traditional classrooms? How do instructors and students use the affordances of flexible classrooms during active learning? Methodology: An instructor at a large Midwestern university taught the course Introduction to Electronics Circuits in a traditional classroom one semester and in a flexible classroom the next. The two research questions were addressed through complementary quantitative and qualitative analyses of video data, classroom observations, and instructor interviews to detail the amount of active learning and the way the instructor facilitated it in the flexible classroom. Findings: The time the instructor devoted to active learning increased in the flexible classroom, while the time she devoted to instructor-led examples decreased. The affordances of the flexible classroom also encouraged more frequent and better student-instructor and student-peer interaction.

Numerous studies have illustrated that participation in occupations--defined as meaningful life activities--is essential to wellness (AOTA, 2014). Social interaction is an important area of occupational participation for children in their roles as students (AOTA, 2014). Classroom design can impact student social participation; however, there is a lack of current research focused on effects of classroom design on social interaction for "all" students. Rather, research has examined factors affecting social participation of certain subgroups of students in the classroom, such as those with chronic illness or deafness (Martinez, Carter & Legato, 2011; Martins & Gaudiot, 2012). While literature provides information about various subpopulations, in this paper we emphasize that social participation based on classroom design can facilitate or inhibit overall occupational participation for all children in the role of student.

This paper presents aspects of a space planning project assigned to Library and Information Studies postgraduate students and reflects on six themes that cropped up repeatedly in their design of a 24/7 postgraduate library space, namely: lighting, space and colour; tools and technology; defined zones; re-bootable spaces; furnishings; and respite. The projects are shown to present students' needs for a varied library space, but one that is primarily for work and study. Disappointingly, the projects did not reflect the needs of disadvantaged or differently-abled students, nor did they display a uniquely South African flavour. Despite the students being members of both the postgraduate user group and the LIS discipline, project omissions led the authors to conclude that, while this group had a lot of value to add, ultimately the library should cast its net as wide as possible when assessing user needs.

Forest harvesting is one of the anthropogenic activities that most significantly affect the carbon budget of forests. However, the absence of explicit spatial information on harvested carbon poses a huge challenge in assessing forest-harvesting impacts, as well as the forest carbon budget. This study utilized provincial-level statistical data on wood harvest, the tree cover loss (TCL) dataset, and a satellite-based vegetation index to develop a Long-term harvEst and Allocation of Forest Biomass (LEAF) dataset. The aim was to provide the spatial location of forest harvesting with a spatial resolution of 30 m and to quantify the post-harvest carbon dynamics. The validations against the surveyed forest harvesting in 133 cities and counties indicated a good performance of the LEAF dataset in capturing the spatial variation of harvested carbon, with a coefficient of determination (R2) of 0.83 between the identified and surveyed harvested carbon. The linear regression slope was up to 0.99. Averaged from 2003 to 2018, forest harvesting removed 68.3 ± 9.3 Mt C yr -1 , of which more than 80 % was from selective logging. Of the harvested carbon, 19.6 ± 4.0 %, 2.1 ± 1.1 %, 35.5 ± 12.6 % 6.2 ± 0.3 %, 17.5 ± 0.9 %, and 19.1 ± 9.8 % entered the fuelwood, paper and paperboard, wood-based panels, solid wooden furniture, structural constructions, and residue pools, respectively. Direct combustion of fuelwood was the primary source of carbon emissions after wood harvest. However, carbon can be stored in wood products for a long time, and by 2100, almost 40 % of the carbon harvested during the study period will still be retained. This dataset is expected to provide a foundation and reference for estimating the forestry and national carbon budgets. The 30 m × 30 m harvested-carbon dataset from forests in China can be downloaded at 10.6084/m9.figshare.23641164.v2 (Wang et al., 2023). [ABSTRACT FROM AUTHOR]

Purpose: This paper aims to present a case study of virtual-reality-based product demonstrations featuring items of furniture. The results will be of use in further design and development of virtual-reality-based product demonstration systems and could also support effective student learning. Design/methodology/approach: A new method was introduced to guide the experiment by confirming orthogonal arrays. User interactions were then planned, and a furniture demonstration system was implemented. The experiment comprised two stages. In the evaluation stage, participants were invited to experience the virtual-reality (VR)-based furniture demonstration system and complete a user experience (UX) survey. Taguchi-style robust design methods were used to design orthogonal table experiments and planning and design operation methods were used to implement an experimental display system in order to obtain optimized combinations of control factors and levels. The second stage involved a confirmatory test for the optimized combinations. A pilot questionnaire was first applied to survey demonstration scenarios that are important to customers. Findings: The author found in terms of furniture products, product interactive display through VR can achieve good user satisfaction through quality design planning. VR can better grasp the characteristics of products than paper catalogs and website catalogs. And VR can better grasp the characteristics of products than online videos. For "interactive inspection", "function simulation", "style customization" and "set-out customization" were the most valuable demonstration scenarios for customers. The results of the experiment confirmed that the "overall rating", "hedonic appeal" and "practical quality" were the three most important optimized operating methods, constituting a benchmark of user satisfaction. Originality/value: The author found that it is possible to design and build a VR-based furniture demonstration system with a good level of usability when a suitable quality design method is applied. The optimized user interaction indicators and implementation experience for the VR-based product demonstration presented in this study will be of use in further design and development of similar systems.

In this paper, an improved VGG16 combined with depthwise group over-parameterized convolution (DGOVGG16) model is proposed to realize automatic furniture image classification. Firstly, depthwise over-parameterized convolution combined with group convolution is combined to construct depthwise group over-parameterized convolution, which is introduced to the VGG 16 model for reducing the number of parameters of the overall model while extracting more sufficient semantic features of furniture images. Then, this paper uses the ReLU activation function in the former part of the neural network to reduce the correlation between parameters and accelerate the weight update speed of the former part of the model. Meantime, the proposed model applies Leaky-ReLU activation function in the last layer to avoid the problem that some neurons do not update. Compared with the six furniture image classification methods based on MobileNetV2, AlexNet, ShuffleNetv2, GoogleNet, VGG 16 and GVGG16, the experimental results show the proposed DGOVGG16 with average accuracy (AA) of 95.51% has better classification performance.

The main aim of the paper is to present an Augmented Reality application for 3D furniture, with a particular emphasis on the development of an android application that provides a realistic view of an augmented reality 3D furniture target object in the real-world. This app for Android would overlay a virtual environment on top of the user's real world. AR makes real-world data and presents it in an immersive manner, making the virtual section feel like it belongs in the real world. AR is commonly used in online shopping, and the 3D visualization allows any furniture piece to be configured. Results shows that, users can customize and combine their favorite furniture products, enhancing their shopping experience. This elevates the shopping experience to a new level. This application allows users to see and experience the object in their current environment before buying from a shop, and customers can visualize the furniture model in a real-world setting.

As the most important forest product in the export of China, wooden furniture is facing increasingly fierce international competition and has a strong need for quality improvement. Based on the endogenous determination model of quality, this paper measures the quality of Chinese wooden furniture in exports from 1998 to 2017, by using product-level trade data of BACI CEPII. From the perspectives of the overall and sub-category quality, it examines the characteristics of dynamic changes in the product quality and its regional distribution of "the Belt and Road Initiative" countries. The results show that the quality of Chinese wooden furniture in exports is lower than that of wood-based panels and paper products. It remains stable after a slight increase from 2001 to 2005, but the quality level is always low. Among the sub-categories, wooden furniture not for kitchens, offices, or bedrooms has the lowest quality, while wooden office furniture has the highest one. The three dominant sub-categories that account for a high export share are all low in quality, while the small proportion sub-categories are all of higher quality, implying a strong imbalance. In particular, the quality of the main export products, upholstered wooden seats and wooden furniture not for kitchen, office, or bedroom use, has continued to decline, highlighting the plight of the quality growth of Chinese wooden furniture. For the BRI markets, the quality of Chinese wooden furniture exported to the region has declined slightly since 2012. However, different markets have shown different characteristics in the quality level and the direction of change. In terms of quality level, the qualities of wooden furniture exported to Malaysia, Israel, the United Arab Emirates, Vietnam, and the Philippines are relatively high. In terms of changing trends, the qualities of wooden furniture to Malaysia, Thailand, Indonesia, and Israel are showing a rising trend. In this case, accurately identifying the quality of different export categories of furniture products and their changing characteristics can help furniture enterprises make better production and operation decisions, promote the formation of a good business environment, and foster new comparative advantages and international competitiveness.

The aim of this paper is to evaluate changes in Italy's competitiveness in the global wood products market, with a particular focus on wooden furniture and wood panels, both final and intermediate products of the crucial wooden furniture supply chain. The analysis is conducted through a cross-country comparison using trade flow matrices and various descriptive indices: Market Share, Trade Competitiveness Index, Balassa's Revealed Comparative Advantage Index, and the Symmetric Balassa Index. Furthermore, this study also examines intra-industry trade using the Grubel–Lloyd Index. While each index has its limitations when used individually, their combined analysis can provide a more comprehensive view. The study covers the period from 1996 to 2019, using data from FAO and COMTRADE sources. The results show that Italy maintains a significant position in the international furniture market, although this position has deteriorated over time. Conversely, Italy remains a net importer of wood panels. Trade flows have become more concentrated, with Canada and Germany still holding importance in the international market. However, Asian countries have now become the core of the commercial network. China has emerged as the leading exporting country in all product categories considered, with Vietnam and Malaysia also increasing in importance. Noteworthy progress has also been recorded by Russia and Poland in Europe. Additionally, the study discusses the implications of these findings for rural development, particularly in regions dependent on the wood-product sectors. [ABSTRACT FROM AUTHOR]

This paper proposes a furniture design method combining Kansei engineering (KE) and shape grammar (SG), to explore how the diagonal ridge elements of classical Suzhou-style buildings can be applied to furniture design and to explain how the styling elements match the cultural imagery in furniture products. Suzhou-style armchairs and cultural elements of diagonal ridges were collected, the most suitable armchairs were selected for incorporating such elements, and their shapes were deconstructed along with characteristic interpretations. A factor bank of diagonal ridge elements was constructed, first through Kansei word selection and evaluation experiments, and then through factor analysis which determined the main cultural elements of the design. The shape grammar theory was applied to design and innovate the selected armchair samples, achieving three design solutions. The solutions were then comprehensively evaluated, and the optimal one was used for the final physical product. The results of the study showed that users had clear subjective feelings about the design incorporating diagonal ridge elements, with their Kansei on three aspects: aesthetic style, decorative complexity, and structural balance. The approach used in this work blends furniture products with cultural imagery on diagonal ridges, providing a feasible methodological reference and an empirical case for cultural sustainability through furniture design.

Within this scientific paper, a brief analysis of furniture design is made, with a concrete analysis of the ancient Greek Klismos chair. About the famous Klismos chair, there are papers and analyses that claim the comfort and daily use of the chair at that time by all people without division. A brief description of the beginnings of the modern era is also made, including how it influenced today's architecture and design. By presenting the first modern chairs as unique and free from the former styles, in symbiosis with the Klismos chair, a new concept design for today's everyday chair is obtained. The Triga chair is minimal and functional, which follows today's trend through shape, material, and color. It is designed to be used for everyday activities and as a dining chair. The research methods used in this paper are the qualitative method, the real and productive analysis, the generalization method, the simulation method, and finally the application method.

In this paper I use group-analytic, philosophical and psycho-social lenses to explore phenomena associated with the convening of an experiential large group within a two-day conference on the theme of "knowing and not-knowing". Drawing in particular on the work of Earl Hopper, two different models of large group convening--in which the chairs for the group are arranged either in concentric circles or in spirals--are described "topographically" and compared in terms of the tasks which each model might address. I argue that the spiral topography may be more suited to the attempt to construct what the conference organisers posited as "insecure edifices of knowledge" and I borrow from the letters of Keats on "negative capability" to suggest that phenomena of "half-knowledge" may be generated and fleetingly perceived within the dynamic processes in the dilemmatic spaces of experiential large groups thus constituted.

This paper explores the possibility of using recycled seashells from marine coasts of the Mali Ston Bay in Dubrovnik-Neretva County, Croatia, to create a novel bio material derived from waste seashells. In this research, two types of waste seashells, mussel (Mytilus galloprovincialis) and oyster (Ostrea edulis), combined with natural, non-toxic binders (bone glue) were investigated experimentally. The goal is to develop a sustainable material, suitable for the production of furniture and decorative objects. The parameters studied, included physical and mechanical properties of this material. The results showed that this bio composite material, derived from recycled seashells, is hygroscopic and has low compression strength. It should be used for making furniture components that don't bear heavy loads and it is suitable only for interior applications. This study presents an eco-friendly and sustainable material option, while optimizing the recycling of food waste materials. [ABSTRACT FROM AUTHOR]

With the popularization of the concept of "metaverse", Augmented Reality (AR) technology is slowly being applied to people's daily life as its underlying technology support. In recent years, rapid 3D reconstruction of interior furniture to meet AR shopping needs has become a new method. In this paper, a virtual home environment system is designed and the related core technologies in the system are studied. Background removal and instance segmentation are performed for furniture images containing complex backgrounds, and a Bayesian Classifier and GrabCut (BCGC) algorithm is proposed to improve on the traditional foreground background separation technique. The reconstruction part takes the classical occupancy network reconstruction algorithm as the network basis and proposes a precise occupancy network (PONet) algorithm, which can reconstruct the structural details of furniture images, and the model accuracy is improved. Because the traditional 3D registration model is prone to the problems of model position shift and inaccurate matching with the scene, the AKAZE-based tracking registration algorithm is improved, and a Multiple Filtering-AKAZE (MF-AKAZE) based on AKAZE is proposed to remove the matching points. The matching accuracy is increased by improving the RANSAC filtering mis-matching algorithm based on further screening of the matching results. Finally, the system is verified to realize the function of the AR visualization furniture model, which can better complete the reconstruction as well as registration effect. [ABSTRACT FROM AUTHOR]

BACKGROUND: Primary school children spend quite a lot of time sitting in classrooms. For this reason, it is necessary to make a scientific analysis of children's body dimensions and compare them with the furniture dimensions where they sit. OBJECTIVES: The main aim of this paper is to present anthropometric data for pupils in primary schools in the Republic of Kosovo and give recommendations for school furniture design. METHODS: Measurements were made in the public schools of four different regions in the Republic of Kosovo. The study includes 720 children from 12 different elementary schools with first and fifth graders (6–11 years old). Twelve body parts were measured: Stature, sitting height, shoulder height, lower leg length, hip breadth, elbow height, buttock-popliteal length, thigh clearance, eye height, shoulder breadth, and knee height. The descriptive data are calculated in terms of average, standard deviation, and 5th, 50th and 95th percentile. RESULTS: We recommend that the competent authorities in the Republic of Kosovo consider improving the infrastructure of primary schools in terms of furniture size according to the findings presented in this study. CONCLUSIONS: The information presented in this paper on pupils' anthropometry and the proposed dimensions for school furniture can be used by various bodies in Kosovo including, but not limited to: Ministry of Education Science and Technology, Ministry of Trade and Industry of Kosovo and furniture manufacturing industries as basic information for suitable furniture design for primary school children, as well as school principals to help in furniture selection.

Interactive tabletops are gaining increased attention from CSCL researchers. This paper analyses the relation between this technology and teaching and learning processes. At a global level, one could argue that tabletops convey a socio-constructivist flavor: they support small teams that solve problems by exploring multiple solutions. The development of tabletop applications also witnesses the growing importance of face-to-face collaboration in CSCL and acknowledges the physicality of learning. However, this global analysis is insufficient. To analyze the educational potential of tabletops in education, we present 33 points that should be taken into consideration. These points are structured on four levels: individual user-system interaction, teamwork, classroom orchestration, and socio-cultural contexts. God lies in the details.
