Throughout the history of furniture design, it’s clear that wood is the most popular material used in furniture making. As one of the common wooden furniture, the strength of wooden chairs is an integral part of the furniture design process as it relates to the user’s experience and safety. Therefore, research on the strength of wooden chairs is becoming increasingly important. The purpose of this study is to test the strength of wooden chairs of different design structures and woods to improve the aesthetics and safety of wooden chairs. The research method is to conduct a quantitative study using the finite element method. with the following specific research process: firstly, a questionnaire survey was conducted to understand people’s subjective impressions and needs for the strength of wood and connection structures. Secondly, the general physical properties of the wood were summarized, and the selected seat samples were modeled with different connection methods, and the model was pre-treated, then external loads were added and finite element analysis was carried out. Finally, the results of the experimental data were analyzed to obtain the optimal strength combinations of different woods and connection methods in the design of wooden seats. The results of the study showed that among all the experimental samples, the white oak seat with a screw-connected structure had an equivalent force of 20.327 MPa and a safety factor of 0.29517, which was the strongest among the 15 experimental samples. The strength of the screw joint structure of all five kinds of wood is greater than that of the Roundwood mortise-and-tenon common structure, while the strength of the Roundwood mortise-and-tenon joint structure is greater than that of the straight mortise-and-tenon joint system. In this study, the strength of solid wood seats was investigated based on the finite element analysis method, which provides specific theoretical support for the design and research of solid wood seats in the future and has particular reference significance for promoting the design and development of solid wood furniture in the future.

In recent years, the sales growth rate of solid wood furniture has been reduced due to the homogenization of product design, in which design factors play a key role in consumer behavior. The purpose of this study is to further understand the impact of design factors on consumers' willingness to buy solid wood chairs by conducting a design factor study on solid wood chairs.The study utilized a combination of literature research method and quantitative research method and was conducted in two phases. In the first phase, design factors, preferences and evaluation factors of purchase intention were extracted from the literature and research hypotheses were set. In the second phase, a questionnaire survey of consumers was conducted using the Richter scale, and a mediation effect analysis was conducted with design factors as the independent variable, purchase intention as the dependent variable, and preference as the mediator variable, to explore the relationship between the design factors of solid wood chairs on preference and purchase intention. The results show that design factors have a positive predictive effect on purchase intention, and the order of importance of each design factor is intensity> material> shape> functionality> cultural> color. Design factors were positively related to preference (β=0.869, t=2.207, p< 0.001). Design factors were positively correlated with purchase intention (β=0.782, t=3.831, p<0.001). Preference was positively correlated with purchase intention (β=0.378, t=9.950, p<0.001). Meanwhile, preference has a significant mediating effect between design factors and purchase intention (effect value of 0.103). This study conducted a preliminary study on the impact of design factors on consumer's preference and purchase intention of solid wood chairs, which can provide a certain theoretical basis for the design and research of solid wood chairs in the future.

During COVID-19, with the implementation of self-isolation and the development of the Internet, which facilitated the rapid development of social media, people became more and more accustomed to communicating with others online. People's sense of isolation was exacerbated by the reduction of face-to-face contact in real life and the expansion of maintaining social distance. Therefore, it becomes more important to enhance people's interaction and communication in urban landscape spaces. Landscape installation is an important medium to guide the interaction between people and their environment. Therefore, the purpose of this study is to gain insights into people's cognitive and emotional responses to the environment by examining the preferences of landscape installations and observing the effects of different design elements on preferences. The research methodology was a combination of qualitative and quantitative research, and 2 phases of research were conducted. First, in the first phase of the study, examples were analyzed and design evaluation index elements were extracted from the works of landscape installations in Han River Art Park in Seoul. In the second phase of the study, a questionnaire survey was conducted for the general public utilizing the Han River Art Park in Seoul. The effect of design elements on the preference of landscape installations was also examined by regression analysis. The results of the study showed that the design elements of landscape installations can be classified as cultural, color, possibility of audience participation, innovation, elimination of loneliness, and functionality. It was found that the preference for landscape installations has a significant positive (+) influence relationship with the six design elements. The influences are, in order, audience participation possibility, culture, color, solitude, functionality, and innovation. This study provides a theoretical basis for future landscape installation design and research.

Mental stress in people’s daily lives is increasing due to economic development and the impact of the COVID-19 pandemic that has occurred worldwide over the past three years. Accordingly, it has become more important to achieve participatory interactions in outdoor spaces. Among them, landscape installation is an important medium for people to interact with landscape space to interact with people. Research on landscape installation preferences helps develop landscape installation design and promotes people to be more involved in the interaction of landscape installations. The purpose of this study is to understand people’s preferences for landscape installations and to facilitate human interaction with landscape installations, landscape spaces, or other landscapes. The research methodology is a combination of qualitative and quantitative research. First, through a literature review, major concepts and prior studies were summarized and the limitations of prior studies were analyzed. Second, the preference for landscape installations is statistically analyzed using the SBE method. Third, I.R.I. image scale analysis of landscape installations, color elements are extracted, and color characteristics of the top 10 landscape installations are analyzed. Fourth, through regression analysis of color elements and SBE values, the level of influence of color elements on landscape installation preferences was analyzed. According to the results, natural colors are used the most frequently among the color application characteristics of current landscape installations, followed by cheerful colors, colorful colors, and decent colors. In addition, it was found that color contrast, colorful color, and cute color had a positive (+) effect on landscape installation preference, and mild color had a negative (-) effect on landscape installation preference. This study provides a preliminary exploration of the color range of preference for landscape installations and also provides reference material for the design and research of future landscape installations. It is important to promote the design of future landscape installations.
