Objectives: Through comparing sleep variables and autonomic activities among three shifts in shift workers, the authors intended to clarify which shift is most tolerable and to identify the characteristics of their psychological and physical problems. This study is also expected to help shift workers to adapt themselves to their work more effectively. Methods: Fifty one shift workers took part in this study. They were working in a rapidly rotating system in which they worked for 3 days in one shift with one day off between each shift. Based on a sleep diary, sleep latency (SL), sleep period time (SPT), and number of wake after sleep onset (NWASO) were estimated and compared among the three shifts. In assessing sleepiness, Epworth sleepiness scale (ESS) and visual analogue scale (VAS) were used. To evaluate mood states among the three shifts, profile of mood states (POMS) was administered. Heart rate variability (HRV), and the level of adrenaline and noradrenaline were measured to assess autonomic activities. HRV included low frequency power (LF), high frequency power (HF), and LF/HF. Results: SPT was significantly lengthened during the evening shift and SL was shortened during the night shift. The workers showed a drop in alertness at wake-up during morning shift and a drop in alertness at work during night shift. During night shift the subjects complained of physical fatigue and cognitive decline. Comparison of HRV showed that parasympathetic activity was most prominent during the evening shift. Secretion of adrenaline and noradrenaline decreased during the evening shift, though statistically not significant. Conclusion: We found that the evening shift was most tolerable among the three shifts. It is recommended that morning light exposure be done during the morning shift and nocturnal light exposure during the night shift.

The purpose of this study is to understand the meaning and essence of aged life, which Korean elderly experience in real life and restructure them in the context of time and culture. In order to do so an in-depth interview was done with 15 elderlies over the age of 60 living in Hwaseong City, an urban-rural composite area in Gyeonggi Province where diverse elderlies could be found. In result, first, Korean elderly's understanding of aged life had physical, familial, economical, leisure, and social restoration aspects. Second, it was found that the degree of understanding about preparation for aging and preparedness is quite low. Third, as the gap between actual preparation for aging and aged life that elderly dreamed of became wider 'resentment on children', 'denial of reality', 'physical and economical change', and 'experience from prolongation of life-cycle' was found. Based on such results following suggestions could be made. First, the awareness of aged life and preparation for aging should be strengthened and there is a need for diverse educations aiming successful aged life. Second, elderly welfare policy and practical intervention with an integrated perspective based on the realm of life-cycle are demanded. Third, there is a need to strengthen the Aged Income Maintenance System for existing elder generation. Fourth, an intervention about adaptation and coping means of life event is needed. Lastly, there is a need to expand and carry out the aged life planning program for future elder generation.

The purpose of this study is to explore and describe the health and welfare needs experienced by old parents living with disabled adult children, and to help generate research interest and public policy attention on this critical issue. For the purpose of this study, the survey was conducted with older parents who are living with dependent adult children with physical or mental disability. Among collected data for this study, data for 105 older parents were analyzed. The results showed that older parents have suffered with care responsibilities for their disabled adult children as well as special needs resulted from their old age. And older parents have little or even nothing prepared for later life because of lifetime economic, physical and social difficulties related to their disabled children. Also these difficulties had a significant impact on their idea of health and welfare needs in later life. It showed that older parents had mainly concerned and wanted to have the direct cash benefits and medical provisions but hardly recognised the importance of other services such as leisure activities. Preliminary suggestions of this study therefore may be helpful to improve the public policy approach in order to better serve older parents with disabled adult children in the coming aging society.

Objectives: This study was conducted to investigate the change of health status through the intervention of physical activity arid exercise program for the people living in the area where health promotion program has been executed. Methods: The data was obtained from self--administered questionnaire. The questionnaire consisted of general characteristics, physical activity transition and health status variables using the SF-36(36-Item Short-From Health Survey). Data were analyzed 134 subjects participating in the physical activity arid exercise intervention programs. Results: The 35.1% of adults above 20 years of age are regularly physical activity and exercise before intervention program. but the rate increased to 49.3% after that. Frequency and duration of physical activity were increased, and frequency of participating in physical activity was increased from 0.9 times a week to 2.1 times especially. Scores of health status measured by SF-36 was increased in category (if general health after intervention of program, but those were decreased in category of vitality and mental health. Physical function of four groups classified by change of behavioral pattern were increased after intervention of program, especially in groups starting to physical activity. Conclusions: Physical activity and exercise is associated with health status. This study suggest that effective strategy and policy supporting for the promotion of physical activity and exercise should be needed in all peoples.

목적 : 본 연구는 척수손상환자들 중 신체활동 정도가 급격하게 차이 나는 운동 선수군과 비선수군의 일상생활동작과 골밀도를 비교 분석하는데 그 목적이 있다. 방법 : 본 연구를 위해 20명(선수 10명, 비선수 10명)의 SCI 환자가 실험에 참가하였다. 골밀도 측정을 위해 이중에너지 방사선골밀도 측정기(Lunar Prodigy, GE Healthcare. England)를 이용하여 종골부위(calcaneus)의 골밀도를 측정하였다. 척수손상환자의 일상 생활 기능을 측정하기 위해 자조관리(self care), 호흡과 괄약근 조절 (respiration and sphincter management task), 이동(transfer)의 세 영역으로 나누어진 SCIM II(Spinal Cord Injury Measurement II)을 이용하였다. 척수손상환자들 중 운동 선수군과 비운동 선수군의 일상생활 동작과 골밀도를 비교 하기 위해 SPSS 14.0 통계 프로그램의 independent t-test를 이용하여 통계분석을 실시하였고 일상생활 동작과 골밀도의 상관관계는 Pearson correlation을 실시하였다. 유의수준은 ${\alpha}$=.05로 통계처리 하였다. 결과 : 검사 결과 선수군이 비선수군보다 통계적으로 유의하게 큰 SCIM 점수와 T-score를 보여주었다. 결론 : 일상생활동작을 측정하기 위하여 SCIM II(SpinalCordIndependenceMeasureII) 척도를 사용하였는데 선수군이 비선수군에 비해 유의하게 높은 SCIM II 총점을 나타내어 운동을 통한 훈련이 척수손상환자의 기능적 활동을 향상시킬 수 있다고 사료된다. 그리고 골밀도 측정 결과 선수군이 비선수군에 비해 통계적으로 유의하게 높은 골밀도를 나타내었다. 이 역시 강도 높은 훈련이 척수손상환자에게 나타날 수 있는 신체구성을 강화시켜줄 수 있을 것으로 사료된다. 운동을 통한 재활 중에서 그 강도가 높을수록 신체의 구성적, 기능적 측면 뿐 아니라 신경의 가소성 측면에서도 증가를 기대해 볼 수 있을 것으로 판단된다.

Movements are a critical ability to young children's whole development, including physical, social/emotional, and cognitive development. This paper proposes the method to estimate movements suitable for young children's body conditions. The proposed method extracts a silhouette in each frame of videos that are obtained by deploying two video cameras by compensating illuminations, removing background and conducting morphology operations. And we extract silhouette feature values: an area, the ratio of length to width, the lowest foot position, and 7 Hu moments. Also, the area and movements of sub-area are used as local features. For motion estimation, we used probability propagation of the features extracted from the front and side frames. The proposed estimation algorithm is demonstrated for seven movements, walking, jumping, hopping, bending, stretching, balancing, and turning.

Recently, with the increasing of the interest in the integration of medical technology and information communication technology, researches on WBAN (Wireless Body Area Networks) that try to apply sensor network to the human body have been processed actively. The existing sensor network technology has the potential to be used in WBAN, but it has some limitations also. In particular, because the sensors are likely to communicate through each part of the body, it has a very different network environment from the sensor network that uses a free space. Therefore, researches on WBAN have a variety area of study that slightly different from the conventional sensor networks and take into account the characteristics of the body. In this study, we investigate the environmental characteristics of WBAN that are separated from the conventional sensor network, and the research trends of WBAN systematically by using the technique of SLR (Systematic Literature Review) from 2001 around when the concept of WBAN has been introduced. The investigation includes the classification of research and the researcher's features. And the survey results and the outlook for further study are summarized.

In this paper, we study the bus stop shelters, one of the public facilities, revised by the development plan of Seoul city. Dark gray and brown are dominant colours for the shelters. As representative colours, designated by Seoul city, dark gray and brown can be harmonious naturally with urban environment. However, in view of universal design, those colours have some problems to be recognized and to be used for handicapped groups, olds and childens especially. For analysis, investigating proposition and circumstance of two groups living in the city is the first place. This study is for building proper colour domains of universal design for public facilities and for recognizing that the way of public facilities should be that the ambit of public space is not regarded as a facility but recognized easily in accordance with environment including a facility. we hope that this paper is practically used as a reference for coming studies are the purposes of this study.
