Objective : This study aimed to systematically examine studies on the life-space mobility in community-dwelling elderly and analyze and summarize the research trends. Methods : The Embase and PubMed databases were searched for articles on the life-space mobility of community-dwelling elderly published between January 2010 and January 2020. Based on the selection and exclusion criteria of the 335 articles, a total of 27 articles were finally selected and analyzed. Results : As a results, 11 (40.7%) cohort studies had evidence level II. This study showed that the participants in the studies were healthy elderly (81.5%), and the University of Alabama Life-Space Assessment (UAB-LSA) used the most participants (88.9%). Of the foci of the 27 finally selected studies, 8 (29.6%) were physical, 8 (29.6%) were psychosocial, 6 (22.2%) were cognitive, and 2 (7.4%) were social, and 3 (11.1%) were others. The life-space mobility of the elderly needs to be analyzed from a multidimensional point of view, and not based on a single factor such as the physical, cognitive, psychosocial, or social. Conclusion : The results of this study are expected to verify causality through the study of life-space mobility for the elderly staying in various communities and provide future directions for the study on the mobility of the elderly's and the development of community-based intervention programs.

Objective : The purpose of study is to validate the clinical utility and usability of the Korean version of the Life Space Assessment(K-LSA) which is an assessment tool of community mobility of older adults. Methods : Surveys on the clinical utility and usability of the K-LSA are carried out with a total of aoaa60 occupational and physical therapists. The surveys included the multiple choice questions on the clinical utility and open questions on the usability. Responses to multiple questions are post processed by frequency analysis and technical statistics, and responses to the open questions are categorized by common factors in each questions. Results : Average value of clinical utility ranges from 3.6 to 4.0 with positive responses of 'fair (3 point)', 'agree (4 point)' and 'strongly agree (5 point)' being 95~100%. Average value for clinical usability ranges from 3.6 to 4 with positive answers of 'fair (3 point)', 'easy (4 point)' and 'very easy (5 point)' being 88.3~100%. Additionally out of open-type questions of clinical usability, it was pointed out that the concept of 'neighborhood' for the life space level 3 and 4 is unclear. Conclusion : The current study and research outcomes showed that the K-LSA is a validated tool in Korean health care system for the clinical utility and usability in measuring community mobility, and that it is straightforward in practical use. It will help clinicians and therapists promote the social participation of older adults, and set an intervention goal for enhancing community mobility. It will further help clinicians and researchers in education and research for medical intervention and goal-setting.

All of propagation path loss prediction models, which have been presented up to date, are oかy for ground living space. In reality, sea surface free space is different from ground living space in physical hierarchical structure. If the propagation path prediction model for ground living space is applied to the sea surface free space, propagation path loss will be smaller than actual value, while the maximum service straight line will become shorter. Thus this paper proposed and simulated the propagation path loss prediction model for predicting propagation path loss more accurately in sea surface free space, with its focus on CDMA mobile communication frequency band. Then the simulation results were compared to actual survey to verify its practicality.

The population of Korean Society is aging rapidly at a pace which is unprecedented in the world. This demographic change results in the various socioeconomic and cultural changes accompanied by spatial changes. The purpose of this study is to examine major characteristics of residential medical facilities for the elderly and the life of those using the facilities of the Capital Region in Korea. Major findings of the study are as follows. The characteristics of the location of residential medical facilities for the elderly and the life of those using the facilities are influenced not only by the mobility of the elderly. but also by the distance between the facilities and Seoul and also by the residential environments of the facilities. The location of the facilities and the mobility of the elderly, followed by the residential location of the family have an effect on everyday life of the elderly.

자동차의 전기차로의 전환과 더불어 IT 기술이 접목된 자율주행기술이 빠르게 발전하고 있으며, 현대기아자동차 그룹을 비롯한 글로벌 완성차 제조사 및 애플, LG 등과 같은 IT 제조사간에 완성도 높은 자율주행차 개발에 치열한 경쟁이 이루어지고 있다. 특히 사람의 개입이 거의 없는 4단계 이상의 자율주행 기술이 적용된 자율주행차는 운전석이 없는 등 기존과는 매우 다른 실내 구조를 가질 것으로 예상되며, 사람에게 움직이는 생활공간을 제공할 것으로 기대된다. 이와 같은 자율주행차 내의 미디어 소비는 고화질 미디어를 대형 화면으로 볼 것으로 예상되며, 지상파 TV 방송은 미디어를 단방향으로 대용량 전송하는데 유리하여 자율주행차를 대상으로 미디어 서비스에 적용성이 높을 것으로 기대된다. 본 논문은 이러한 미래 자율주행차가 제공하는 움직이는 생활공간에서 TV를 시청하는 '이동TV'를 염두에 두고, 현재의 4K-UHDTV 시대 및 미래의 8K/Post-8K 시대의 비용 효과적인 지상파 TV 방송망 기술을 소개한다.

This paper examined the changes of urban system through the network and the flow pattern reflected in daily movement in Korea. Because daily movement reflects trip pattern, urban system formed by inter-city linkages can be recognized in terms of living sphere. While population movements between cities have the number of linkage systems of city network and the number of traffic regions composed of the origin and destination has increased respectively. Nevertheless, spatial extent of Capital region and Busan region has been expanded. In Gangwon-do in which Seoul-oriented high-speed transportation network has developed, separation of living sphere between Yeongdong area and the Soyanggang cultural region formed around Chuncheon was intensified. Living sphere that includes Daejeon and the surrounding cities has been expanded to the southern Gyeonggi-do. The existing living sphere formed in Jeollanam-do was fragmented into the east and west around Mokpo and Suncheon due to the weakened centrality of Gwangju. Living spheres formed by spatial interaction were consistent with regional administrative boundary. Considering the increased interaction between Seoul and its surrounding cities, the development of global city-region centered on Seoul is expected.

The fully autonomous vehicle, which has been actively studied in a worldwide before commercialization, is expected to become a living space by securing time and space compared to existing automobile. For this reason, interior design of fully autonomous vehicle has become very important. To enhance passenger's experience and satisfaction in fully autonomous vehicle, it is necessary to design an optimized space that can support in-vehicle activities. For this purpose, efforts to analyze the passenger's in-vehicle activities should be preceded. However, there were limited studies that define space and in-Vehicle activities of fully autonomous vehicle in Korea. The purpose of this study is to suggest the guideline of the interior design of fully autonomous vehicle by analyzing and classifying the scope of activities that the passenger can perform within the vehicle. As a method of the study, literature studies on future concept cars, human lifetime behavior and consumer needs had been conducted. As a result in-vehicle activities could be applied in a fully autonomous vehicle. Four in-vehicle activities 'work', 'home life and personal care', 'relaxation' and 'conversation and hobby' had been derived through the analysis of in-vehicle activities. Based on the results, the interior design of fully autonomous vehicle guideline has been suggested. The study is significant because the result of the study can act as a basic study which considers the activities in the fully autonomous vehicle environment.
