The aim of this research is to investigate the demographic characteristics of the purchase tendencies and shopping trends amongst female golfers and how these are influenced by their life style and to analyse their selection criteria for purchases of golf-related items. The research methodology was through the use of questionnaires, completed by female golfers in Gyeongnam. The results are as follows: life style trends of male golfers were analysed to be categorized into one of the following: the shopping-addicted, fashion-conscious, rationalist and family oriented spenders. The characteristics of these categories are described as one of the following: utilitarian-complacent, rationalist, self-worshipping, inconsiderate. The demographic characteristics showed notable variations only in age differences. The obtained results show that the influences of the variables are minimal and there was no notable correlation. Significant differences were observed from one life style group to another, in selection criteria for purchase, which mainly depended on style, design, colour, pattern, designer-label, co-ordinated looks, similarity, ease of maintenance and functionality. Comparisons were made between the previously categorized life-style-groups and notable differences were present in such characteristics as ostentatious, trendy, aesthetically pleasing and functional.

An eco-CMF design process is vital to the sustainable development of fashion products concerning both emotional and physical quality factors, thus extending the use phase of the product life cycle. Life cycle assessment (LCA) is widely used in other fields to evaluate environmental impact; However, the method is rarely adopted in fashion. While cooperating with design, technology, and the users, reflecting the CMF design process is an excellent approach to the sustainable development of fashion products. Moreover, it is likely to evoke favorable reactions in users toward products. Therefore, this study aimed to review the sustainable design strategies associated with CMF in the fashion industry. Using a systematic review, 135 papers that met the inclusion criteria were examined from peer-reviewed journal articles published between 1990 and 2022. They contained specific design processes or tools relevant to eco-CMF design. The search used the Web of Science database. After a rigorous search, the final six peer-reviewed journal articles were selected and underwent thorough content reviews. Then, the CMF design tools and frameworks for eco-design featured in the articles were carefully reviewed and analyzed. Finally, we proposed practical guidelines for the sustainable development of eco-CMF design in the fashion industry. The study outcomes revealed the need for concrete eco-CMF design processes, particularly for fashion products. Furthermore, more active research involving eco-CMF design processes for the sustainable environmental impact of fashion products is required.

The influence of environmental conditions on the ganoderic acid (GA) content in the fungus Ganoderma lucidum was investigated using a one-factor-at-a-time design and orthogonal design. Among the various medium components examined, sucrose, soybean powder or peptone, ferrous sulfate, and pH 6.0 were the most suitable carbon source (factor A), nitrogen source (factor B), mineral source (factor C), and initial pH (factor D), respectively, for the GA content in the one-factor-at-a-time design. According to the orthogonal design, the order of effect for the four factors on the GA content was A>C>D>B. The best level of factor A was $A_2$ (sucrose) with a value of +0.34 mg/100 mg DW. The optimal treatment combination was $A_2B_1C_3D_1$ with which the GA content reached up to 2.63$\pm$0.011 mg/100 mg DW. The interactions between the mineral ion and the nitrogen source, and the mineral ion and the pH were both highly significant (P<0.01). The highest interaction effect was ($B_2{\times}D_2$) with a value of +0.19 mg/100 mg DW, which was higher than the level effect value for $B_2$ (peptone) and D$_2$ (pH 5.0). Therefore, the results proved that interactions between factors cannot be ignored. The results also indicated the importance of the interactions between the factors, which may help to understand the metabolic pathway leading to triterpene biosynthesis and the expression and regulation of the key enzymes involved.

Purpose: Sports activities for life are an opportunity to fulfill the basic desire to be healthy and participate in society of the individual level, and it is also the realization of the trend of living together with persons without disabilities and persons with disabilities at the level of social inclusion. I try to propose to improve sports participation of persons with disabilities from the point of view of 'Universal Design.' Methods: Firstly, analysing of previous studies which to classify the barrier free certification standards to universal design's 7 principles and which to investigate public sports facilities. Secondly, reanalyzing, based on UD 7 principles, the raw data of the research results of public sports facilities in Seoul. Thirdly. then, I suggest the improvement plan to promote public sports facilities for all the people including persons with disabilities. Results: The results of this study are that although the facilities have the basic accessibility, there were some inconveniences in using the facility for the elderly and the disabled. So I suggest a few method to improve the public sports facilities from the perspective of universal design : 1) Needs to expand 'Bandabi Sports Center' as a sports facilities for sports activities for life of all of people, 2) Needs to improve accessibility of existing public sports facilities and to raise awareness for the persons with disabilities and universal design, 3) Needs to produce 'UD guidelines' for the sports facilities.

Chinese auspicious element is a kind of art which is used to express yearning of a happy life. It is one of the great treasures of China, with not only emotional value of the people but also an aesthetic value. Chinese auspicious element derives from the aspiration of luck, enthusiasm of life and conciseness of eliminating malicious. It is of great cultural connotation and widely used in interior design, graphic design, fashion design and such. There are many research papers on application methodology of auspicious elements; however, there are very limited research papers on three-dimension product, let alone application in tableware. This paper focuses on illustration of Chinese representative auspicious element "auspicious fish" in tableware design. The research of its application of auspicious element's styling characteristics is of important significance in auspicious element spread and tableware design. This dissertation aims to provide referential design methodology and experience for later researches on related topic.

This study aimed at examining the mediation effects of depressive symptoms on the association between social activity participation and marital satisfaction among couples in later life. The study included 1,196 married couples aged 65 or above who participated in the 7th Korean Longitudinal Study of Aging in 2018. The study variables were husbands' and wives' social activity participation, marital satisfaction, and depressive symptoms. Covariates were individual age, education level, subjective health, couples' household income, and number of children. The Actor-Partner Interdependence Mediation Model (APIMeM) and bootstrapping techniques were used to test the significance of the mediating impacts of depressive symptoms based on the dyadic data structure. The results showed that for both husbands and wives, active participation in social activities had significant effects on increasing marital satisfaction through lowering depressive symptoms. However, only the participation of husbands in social activities was positively associated with their own marital satisfaction by reducing their own and their partner's depressive symptoms. These findings suggest that the active social participation of individuals salient for promoting the quality of marital relationships in later life, particularly for preventing their own and their spouse's depressive symptoms.

In this paper, welding pitch optimization technique of vehicle subframe is presented considering the fatigue life of spot welding nuggets. Fatigue life of spot welding nuggets is estimated by using the frequency-domain fatigue analysis technique. The input data, which are used in the fatigue analysis, are obtained by performing the dynamic analysis of vehicle model passing through the Belgian road profile and also the modal frequency response analysis of finite element model of vehicle subframe. According to the fatigue life result obtained from the frequency-domain fatigue analysis, the design points to optimize the weld pitch distance are determined. For obtaining the welding pitch combination to maximize the fatigue life of the spot welding nuggets, 4-factor, 3-level orthogonal array experimental design is used. This study shows that the optimized subframe improves the fatigue life of welding nugget with minimum fatigue life about 65.8 % as compared with the baseline design.

Long-life housing means a housing which structural members (Support) such as columns and floor are maintained for a long period of time and the housing can be used for approximately 100 years by replacing components (Infill) such as walls and furniture. The government established "Certification standards of long-life housing construction" on December 24, 2014, requiring the long-life housing certification for construction of apartment houses for over 1,000 households. However, it is necessary to prepare an incentive measure which could be granted to construction related personnel and housing owners due to the effectiveness of such system and recognition that the initial construction cost of long-life housing is high. The purpose of this study is as follows. First, the reasons and necessity of long-life housing cost increase for each construction company, housing owner, infill component manufacturer and designer which are long-life housing related personnel are determined. The direction of incentive grant for supplying long-life housing based on the determined items is established. The result of this study is as follows. First, a special treatment which is higher than the alleviation of construction standards according to the previous ordinance is necessary for construction companies to secure the business feasibility. Also, incentives such as the provision of service space and wide balcony are necessary to improve the preference level of parceling out. Second, financial incentives such as financial support for housing purchase, reduction and exemption of tax (acquisition tax and registration tax), and support of maintenance cost are required for house owners. Third, it is essential to increase opportunities to participate in the market for infill component manufacturers by applying additional points for PQ. Fourth, it is needed to provide compensation for additional human resource and time at the time of designing to designers by preparing the long-life housing design cost standards.
