The radon concentrations were measured to survey distribution of radon concentrations in Seoul subway stations. The radon concentrations in air and water were measured at seventeen subway stations(Mapo, Chungjongno, Sodaemun, Kwanghwamun, Chongno3ga, Ulchiro4ga, Tangdaemun, Sangildong on Line 5;Nowon, Chunggye, Hagye, Kongnung, Taenung, Mokkol, Chunghwa, Sangbong, Myomok on Line 7) using the $RAdtrak^{TM}$ radon gas detector, Pylon AB-5 continuous passive radon detector and liquid scintillation counting method from January to May 1999. The major results obtained from this study were as follows: The long-term mean concentrations of radon were $61.8\;Bq/m^3$ in office, $78.9\;Bq/m^3$ in platform, $38.2\;Bq/m^3$ in concourse and $20.1\;Bq/m^3$ in outdoor, respectively. These levels were less than the action level ($148\;Bq/m^3$) of the U.S. EPA. The highest level of short-term mean concentrations was $116.55\;Bq/m^3$ at Chongno3ga station on the 5th line subway stations, while the lowest mean concentration was $19.55\;Bq/m^3$ at Mokkol station on the 7th line subway stations. The highest concentration of radon in the road water and storing underground water in the subway stations was $234.7\;KBq/m^3\;and\;155.5\;KBq/m^3$ in Sodaemun subway station, respectively. The results suggest that radon concentration in subway stations seems to be affected by ventilation and radon concentratin in underground water in the subway stations.

The propose of this study was to investigate the influences of adolescent’s volunteer service activity on perception toward the elderly. The subjects of this study were 556 students who were selected at random from the second grade of high school in the city of Daegu. A questionnaire was used as survey method. Factor analysis and ANOVA were employed for data analysis and Scheffe test for post-hoc analysis. The main findings were as follow: First Adolescent’s perception toward the elderly was hardly different according to the adolescent’s overall volunteer service activity. The participation attitude, the whole participation time, and the voluntary participation time of the adolescent’s overall volunteer service activity had no effect on the adolescent’s perception toward the elderly. But adolescents who were high in the degree of the participation satisfaction with overall volunteer service activities had a more positive perception on social aspect of the elderly than those who were low in it. Second, adolescent’s who participated in volunteer service activities for the elderly showed a noticeable difference in their perception toward the elderly. adolescents who participated in volunteer service activities for the elderly, those who had a enthusiastic participation attitude over volunteer service activities for the elderly had a more positive perception of the family-relationship and social aspects of the elderly than those who had a passive participation attitude in it. Futhermore, adolescents who were high in the degree of the participation satisfaction over volunteer service activities for the elderly had a more positive perception of the family-relational and social aspect of the elderly that those who were low in it. Also adolescents, who spent a lot of time in whole and voluntary participation over volunteer service activities for the elderly, had a more positive perception of the social aspect of the elderly than those who spentless time.

Interior Coordination is the activity of making characteristic living space by planning and harmonizing various interior elements. In modern society, the taste and needs of the residents are getting varied and segmented, and the role of interior coordination is getting more important because that reflects cultural codes and trends and satisfies residents' needs. This study aims to investigate awareness and needs about interior coordination targeting apartment residents, and to provide fundamental data that could attribute to the planning of unique and diverse residential spaces. Methods of study include the literature research and the empirical study. Elements of interior coordination were extracted through the literature review, and the questionnaire was developed using these elements. And then a survey was carried out targeting apartment residents of Busan. The result shows that most of the residents were much interested in interior coordination, and they recognized it's importance. They wanted to plan and select the elements by themselves, but were passive in actual execution because of the difficulties in execution methods and economical conditions. There were certain differences between the styles of their own houses and the preferred styles, but they did not try actively to reconcile the differences. Therefore, various methods of interior coordination should be developed and proposed which are easy and effective for actual execution, and various media should be provided by which residents could easily get informations on design elements. Also, the concept and method of interior coordination should be considered from the very first stage of residential planning, and the replacement and modification of interior coordination could be easily done according to the change of life cycle and life styles.

Objective: This study aimed to investigate the effect of adding hip abductor strengthening to conventional rehabilitation on muscle strength and physical function following total knee replacement (TKR) for knee osteoarthritis. Design: Randomized controlled trial Methods: Thirty-five participants were randomly allocated to exercise groups I (n=18) and II (n=17). Group I underwent hip abductor training and conventional rehabilitation for 30 min per day, 5 days per week for 4 weeks. Group II underwent conventional rehabilitation for 30 min per day, 5 days per week for 4 weeks. The participants in both groups also received continuous passive motion therapy for 15 min per day, 5 days per week for 4 weeks. To investigate the effect of the intervention, the Biodex dynamometer was used to measure the peak torque of both knee extensors and hip abductors. This study used the Knee Outcome Survey-Activities of Daily Living Scale (KOS-ADLS) to assess physical function, as well as the figure-of-8 walk test (F8W) and the stair climb test (SCT). Results: According to the interventions, exercise groups I and II showed significantly improved muscle strength and KOS-ADLS, F8W, and SCT scores (p<0.001). Compared with that of exercise group II, exercise group I showed significantly improved hip abductor strength (p<0.001) and KOS-ADLS, F8W, and SCT scores (p<0.05). Conclusions: The results of this study indicate that the combination of hip abductor strengthening and conventional rehabilitation is an effective exercise method to increase hip abductor muscle strength and physical function after TKR.

최근 빈번한 재난, 재해발생으로 인해 구조물의 점검 및 유지관리가 국가적으로 매우 중요한 요소가 되었다. 구조물 점검은 대부분 인력에 의한 육안조사에 의존하고 있어, 취득 자료의 객관성 결여 및 환경적 특성에 따른 접근성의 한계로 인한 정량적 자료 취득이 불가한 경우도 발생되고 있다. 따라서 이러한 직접적인 육안조사의 한계성을 극복하고, 표준화된 조사데이터 수집을 위해서 비접촉식 자료 취득 방법인 레이저스캐너를 활용하여 구조물의 변상을 탐지하는 연구가 활발히 진행되고 있다. 하지만 현재까지는 현장에서 레이저스캐너를 이용하여 취득된 점군자료를 수동적으로 변상에 의한 기하학적 특성을 다시 정의해야 하는 작업이 요구되었다. 본 연구에서는 인력접근의 한계성을 고려한 자동화된 유지관리 적용을 위해 레이저스캐너의 반사강도를 이용하여 구조물의 열화에 따른 위해요인(백태, 누수, 박리 등)을 탐지할 수 있는 방안을 모색하였다. 연구수행결과 백태, 누수, 박리와 같은 구조물의 열화현상에 대한 탐지가 가능하였으며, 변상유형에 따른 반사강도 특성을 규명함으로써, 향후 유지관리 시 자동화된 변상유형 분류 및 폴리곤 영역의 객체화 가능성을 확인하였다. 구조물의 점검 및 유지관리 측면에 있어 레이저스캐너의 반사강도를 이용하는 방법은 매우 효과적인 것으로 결론을 얻었다.

This study was to identify the nursing intervention method in finding out the incidence, risk factor, prevention and treatment of bed sore cilents who received regional home care nursing services. The eleven home care nurse practitioners took the survey on 97 patients who received home care nursing service from Seoul City Nurses Association for one month from September 26 to October 26 1996. A modified version of Braden's bed sore assessment tool for bed sore risks and a tool for assessment of bed sore stage and measurement bed sore sizes by Bergstrom, Braden, Laguzza and Holman(1987) were as research tools for this study and a questionnare with 40 questions and 12 items on nursing activities was used to find out the prevention and treatment of bed sores. Also, two open ended questions were used on current approaches and efforts of the treatment being applied to clients. The finding of the study were summarized as following : 1. The rate of bed sore occurrence was 47.4% 2. The areas of bed sore occurrence were hip(28.9%), sacrum(18.6%), great trochanter(14.4%) and the average number of sore spots were 2.26 3. Two groups-one with bed sores and the other without-were studied to determine prediction factors for bed sore risks. Sensory function, humidity, level of activity, mobility, nutrition, skin friction and chapping and body temperature turned out to be statistically significant factors for bed sores. Also the age of clients turned out to be a individual characteristic variable significantly affecting the rate of bed sore occurrences. 4. The education for clients and family on systematic skin assessment and bed sores and practice of active/passive R.O.M. are mainly used as nursing activities for bed sore care. 5. The treatment method varied by stages of bed sores. Sometimes folk remedies like applying the powders of dried elm tree roots to sores were used. Good nutrition, frequent position change and skin care turned to be the most effective means to fast recovery of sores.

The purpose of this study is to find out the impacts of VTS on the marine safety and users' opinion on the VTS which have been being operated in the port of Pohang for the last 3 years and is to suggest a guideline to the successful operation of VTS in the future. This study is based upon the questionnaire survey and the respondents include 236 masters/mates of merchant vessels who have visited the port of Pohang and 6 pilots who have been working in the port. From the questionnaire results, this study notes the following conclusions related to the VTS operations. (1) A few of the respondents (mainly foreigners) do not understand the entering procedure of the port and the fundamental concept of VTS. Accordingly, the more active VTS services have to be provided for the mariners. (2) It was found that themost dangerous factors in tehvicinity of the port were the floating materials, fishing nets, andillegal fishing activities inthe fairway. Therefore, the proper surveillance, stricter enforcement of Acts and the instructive education for the fishermen are required to avoid the risks. (3) A majority of the respondents agreed the VTS has contributed to the safety of vessel traffic, and they pointed out ' the assiatances in reduced visibililty conditions' is the most important task of VTS. The amount of 75.6% of the respondents answered that they have experienced the assistance from VTS more than 1 time since the system was established in the port of Pohang . Also 44.2% of the respondents considered they were able to avoid marine casualties such as collision, ramming or agrounding with the VTS assistances. (4) 49.2% of the respondents preferred the passive information services , while, 38.8% of them preferred the positive control advices in the case of encountering any potential risks. VTS iperators have to consider seriously when they provide the positive control advices of ship's course and speed. (5) A majority of the respondents confirmed that the prot and its approaches is suitable for the VTS coverge . To extend the service areas of the VTS and to improve radar detecting ability, the use of radar transponders are seen as the ideal method. (6) A minority of the respondents pointed out 'the improper orders or recommendatinos caused by the poor decision making' firstly, ' the language problem(sea-speaking in English)' secondly, as the deficiency of personal qualification. It seems, therefore, theat the personal efforts of the operators and systematic training programmes for them are necessary to solve the problems.

빛은 인간 생활을 결정하는 중요한 요소이다. 인류가 인공적으로 빛을 다룰 수 있게 된 이래 조명은 도시의 야간문화와 경관을 획기적으로 바꾸어 놓았다. 야간 경관은 도시의 정체성에 지대한 영향을 미친다. 시민들의 야간 활동이 늘어나면서 조명에 대한 다양한 요구가 늘어나는 추세이지만, 정작 경관을 다루는 조경 분야의 계획 설계과정에서 조명계획은 비중 있게 다루어지지 않았다. 본 연구는 우리나라 도시공원의 야간경관의 실태를 분석하기 위해 공원의 계획 및 조성 과정과 제도적 측면의 문제점을 파악하고, 여의도공원을 대상으로 도면 분석과 현장 조사를 통해 문제점을 도출하였다. 현재 도시공원의 야간경관과 관련한 실태 분석의 결과는 다음과 같다. 첫째, 공원의 계획 설계 과정에서 조명계획은 설비 분야에 포함되어 개략적인 수준으로만 다루어져왔고, 이는 실제 공원의 단조로운 야간경관을 초래했다고 볼 수 있다. 따라서 공원의 분석-계획-설계-시공-관리 과정에서 야간경관의 연출을 적극적으로 수용할 수 있는 방법론이 개발되어야할 것이다. 둘째, 현재 도시공원에 적용 가능한 기준은 한국산업규격(KS A 3011)의 수평조도 규정에 그치고 있어 야간경관 평가와 계획의 세부 기준 항목을 다양하게 개발할 필요가 있다. 셋째, 성장하는 수목과 복합적인 자연생태계의 특성을 고려할 수 있는 야간경관 설계 및 관리 방안이 필요하다. 넷째, 공원의 공간별 특성에 맞는 세부 디자인 가이드라인과 관련 기준이 필요하다.
