The purpose of this study was to identify the general characteristics of test subjects in association with three planned housing alternatives in different focus level of work opportunities, leisure activities and services. Subjects used in the study were people in their 50's who were surveyed in 2002. A total of 464 subjects were selected from 556 samples. Statistical significance was found between the preferred housing alternatives and the subjects' background including education level of the subjects and their spouses, monthly income, assets, subjective economic capabilities, and housing size. However, there was no statistically significant differences in recognition of housing problems for later life among groups. Groups selecting different planned housing alternatives showed statistically significant differences for some features of the senior housing. From these results, it is proposed that various designs based on the levels of work opportunities, leisure activities, and services for the senior housing should be provided to satisfy the demands.

Purpose: In our country, the aged population accounted for about 13% of the total population in 2018. In addition, it is expected to exceed 20% in 2026, entering an super-aged society. However, the senior welfare housing in Korea currently accommodates only 0.08% of the elderly population, and the increasing amount of the elderly population is very small. Accordingly, this study aims to analyze the causes of supply shortages and to propose directions for revitalizing the supply of welfare housing for the elderly in the private sector. Methods: First, the causes and problems of the poor supply of welfare housing for the elderly were analyzed. Next, the direction was proposed through institutional and case-by-case surveys and expert interviews. Results: It suggested directions such as legal and institutional improvement, inducing the use of REITs, preparing policies to support consumers, allocating a certain percentage of senior welfare housing for the elderly in the reconstruction project, improving awareness of monthly living expenses, and re-discussing sales permits. Implications: Experts said that the direction proposed in this study can have a positive effect on supply activation. However, there were many opinions that re-discussion on permission for sales was necessary due to the excessive impact of the inability to sell. In addition, further research is needed for specific application of the proposed direction.

Objective: The purpose of the study is to develop quantitative usability evaluation criteria for senior-friendly autonomous transportation robot. Background: The Republic of Korea has become the most rapidly aging society, and is anticipated to enter the post-aged society in 2026. To raise the quality of life of a senior with limited mobility and to reduce the burden of caregivers, many high-tech assistive products with information technologies are developed nowadays. The senior-friendly autonomous transportation robot is one person robot vehicle to move a senior to the destination for hospitals, nursing homes or silver town complex. With built-in navigation system and environmental monitoring censors, it automatically seeks the path to the destination and avoids collision to obstacles and pedestrians on the way. Due to the early stage of the product, few usability studies in this field have been done, mostly on general service robots to assist seniors, power wheelchairs and delivery robots. ISO and KS standards for the service robots are focused on safety. Method: Based on the reference usability index, the early draft of the usability evaluation questionnaires was developed. After small group tests and interviews, the experts modified the initial draft to the Usability Evaluation Criteria for Senior-Friendly Autonomous Transportation Robot (UEC-SFATR). Result: UEC-SFATR consisted of 4 subscales - Safety, Controllability, Efficiency and Satisfaction. All of the 4 subscales of UEC-SFATR were passed the reliability criteria by 4 groups of seniors, divided by gender and familiarity of smart-devices. Conclusion: UEC-SFATR covers wider area of user experiences of the SFATR and is a good measurement tool to help both the users and developers of the robot. Application: This study provides guide to the future product development and product competitiveness evaluation by quantifying user experiences for the SFATR.

본 논문은 SAW태그를 이용하여 환자의 위치를 파악하고, 바이오 센서를 활용하여 재택환자의 상태를 집안의 사람들에게 쉽게 전달하며, 위급상황에 대처가능한 시스템의 개발에 관한 것이다. 일반적으로 집안에서 환자가 가장 많이 다치는 장소는 화장실이고, 개인의 프라이버시가 지켜져야 하는 점과 환자의 상태를 확인하고 위급시 대처해야 하는 부분이 첨예하게 대립하는 지점이므로, 개인의 프라이버시를 지키면서 재택환자의 상태를 모니터링가능한 방법을 고안하였고, 관련 시스템을 제안한다. 또한 SAW 태그를 이용하여 사용자의 위치도 확인가능한 위치 확인 시스템도 연동할 수 있도록 제안하였다. SAW태그는 송신기에서 오는 전파를 그대로 전송하며 자신의 고유 아이디를 전달할 수 있어 3차원 위치 측정에 유용하고, 이를 사용자의 의복에 부착할 경우 입체적인 위치를 측정할 수 있어 생체신호와 같이 정보를 전달할 경우 요양원 같이 많은 환자를 관리하는 종합적인 환자관리 시스템으로 활용이 가능한 장점이 있다. 본 연구에서는 상기의 상태 및 위치 측정 시스템을 구현하여 정상적으로 구동되는 것을 확인하였다.

The costume culture of ladies in late Goryeo is an important and rare source for cultural fashion souvenir design. This study investigates the historical costume design sources of late Goryeo to suggest high quality traditional and practical ornament souvenir designs for female dolls as well as examples of coordination with doll costumes. The costume culture of late Goryeo contained golden Buddhism and a revival of $12^{th}$ century Goryeo costume characteristic after the period of Mongolian influences from the Yuan. The main sources for doll ornament designs are $14^{th}$ century Buddhist paintings, a few ornament relics of Goryeo, ancient literature, and portraits of ladies in the $14^{th}$ century that originated from five doll's traditional ornaments (lotus hairpin, cloud-shaped hairpin, Buddhist flower hair ornament, vase-shaped Binyeo, and bell of animalhuman face) and three wig designs (wigs from Buddhist paintings and portraits, and hairpiece) with bleached gilding silver, silk, various gemstones and synthetic hair. These doll ornament and wig designs imply the symbol of Buddhism, exorcism, and costume culture of $14^{th}$ century Goryeo ladies that can be matched with two doll gowns, half-sleeved jacket, skirt, two Jogoris, apron, under trousers as formal, semi-formal, and town-wear according to the T.P.O of late Goryeo; in addition, five ornaments can be used as owner's ornaments. The partial changing colors and materials due to the characteristics of doll ornament goods as well as better communication between researcher and constructor remain to be improved.
