Korean society is running fast toward a super aging society. This means that new solutions for new problems of aged people are needed. An important area to prove is the aging-friendly neighborhood environments supporting casual contacts and meetings of old residents. This study attempts to suggest neighborhood design indicators which support casual contacts and meetings of old residents. The subjects were 24 professionals who had studied on housing environment for the elderly. They answered through the on-line questionnaire. The questionnaire consisted of items which evaluate the appropriateness of classification of neighborhood area and the indicators of each area using 5-points Likert scale. Also open questions asking adding or eliminating areas or indicator and other opinions were included. On the basis of these answers, the aging-friendly neighborhood design indicators supporting contacts and meetings of old residents was developed. They are consisted of 7 areas in neighborhood and 60 indicators. Those areas were semi-public residential area, commercial area, cultural & educational area, health & medical area, park & green area, walkway, and public traffic facilities. This would be used to design the neighborhood environments that are aging-friendly and facilitating casual contacts and meetings of all residents, especially old residents.

This article is a narrative review that discusses the recommended sample size requirements to design a pilot study to assess the reliability of a questionnaire. A list of various sample size tables that are based on the kappa agreement test, intra-class correlation test and Cronbach's alpha test has been compiled together. For all calculations, type I error (alpha) was set at a maximum value of 0.05, and power was set at a minimum value of 80.0%. For the kappa agreement test, intra-class correlation test, and Cronbach's alpha test, the recommended minimum sample size requirement based on the ideal effect sizes shall be at least 15, 22, and 24 subjects respectively. By making allowances for a non-response rate of 20.0%, a minimum sample size of 30 respondents will be sufficient to assess the reliability of the questionnaire. The clear guideline of minimum sample size requirement for the pilot study to assess the reliability of a questionnaire is discussed and this will ease researchers in preparation for the pilot study. This study provides justification for a minimum requirement of a sample size of 30 respondents specifically to test the reliability of a questionnaire.

Distance Learning Education has been adopted as an alternative educational method to actively face the changing educational field. Fashion design education essentially requires not only a theoretical but also a practical process in which feedback comes through personal interactions between an instructor and a student. Hence, the existing WBI system exemplifies its limitations by applying only a one-way methodology that limit interactions based only on the theoretical texts. The objective of this study was to reveal the effects of an originally designed Distance Education program factoring in a teaching-learning methodology that addresses the practical demands of a fashion design program. So It analyzed the pre-existing conditions through a questionnaire survey of 472 students and 60 fashion design instructors to determine how the traditional fashion design education is different from other programs and which method is being applied. then, It designed and applied an original web-based distance educational system specifically incorporating the needs of the fashion design curriculum based on the data collected from the survey questionnaire.

The purpose of this study was to investigate the demand for functional elements of sports climbing shirts. Questionnaire survey data were collected from adult (n=53) and adolescent (n=55) sports climbers. The questionnaire explored respondents' sports climbing activities and need for functional design features of sports climbing shirts. Their design preferences and purchasing value were also investigated. The results showed that respondents regarded ergonomic design and the use of intelligent material as important elements of expert-level sports climbing shirts. Compared to adolescent, adult respondents were more susceptive to functional design elements such as suitability for climbing motions and ease of dressing or undressing. Also, adult sports climbers were more likely than adolescents to prefer shirts that are tightly fit at the chest. Neither adults nor adolescents favored shirts design that is tightly fit at the neck or armpit. The regular shirts length not covering hips and sleeve length ending at the wrist were preferred. The collar stand should not hit the chin. Adult climbers preferred ergonomically designed sleeves on the back shoulder. Adults and adolescents had different preferences for the front neck zipper length. Adults preferred long front zipper length at chest. These findings suggest that sports climbing shirts should have functional features to prevent interference with climbing movements and improve convenience and stability.

The purpose of this study is to develop the sustainability indicators for assessing environmental sustainability of building. This reseach focused on evaluating indicators for passive design in the stage of site planning and building massing. In order to achieve the aims of this study, first priority was given to set up systematic framework of sustainability indicators for passive design. Based on the framework, the assessment categories and indicators by each category were established. Secondly, the weighted value of each indicators were obtained by questionnaire survey of the experts. As the result of the analysis of questionnaire of experts, feasible indicators were obtained and the grades of measured values were deduced. Finally, this paper presented comprehensive environmental sustainability indicators which is related to the passive design.

The primary objectives of this research are to survey actual condition and propose the improved standard size for office chairs. In order to accomplish this objectives, questionnaire method was used. The subjects for investigation are 271 office sedentary workers from 19 office workplaces. The survey of a actual condition showed that the office chairs included many contr- oversial points which cause occupational health problems. The main causes of office sedentary worker's health problems are insufficient adjustabilities and inappropriate design specifications. Expecially, insufficient adjustabilities led harmful sitting postures. To improve the existing Korean standard size for office chairs, anthropometric procedure was developed. In this approach, six design factors were determined, that is, seat pan height, seat pan width, seat pan depth, seat pan inclination, armrest height and width. The study found that improved Korean staneard size was strikingly different from existing standard.
