이 연구의 목적은 여자고등학교에서 실행한 건강체력교실 프로그램 참여 학생의 교우관계 변화를 조사하는 것이다. J고등학교 비만 여고생 17명(≥ BMI25)이 참여하였다. 단일집단 사전-사후설계를 이용하였다. 건강체력교실 프로그램 운동시간은 1일 평균 110분, 운동강도는 METs=7.71로 9주간 실시하였다. 연구자료는 사전·사후 Name Generator Question과 방과 후 모바일 네트워크상의 대화 내용을 이용하였다. 자료분석은 사회연결망 분석방법 중 밀도, 집중도, 중앙성 및 구성집단 분석을 실시하였으며, 방과 후 모바일 네트워크 상호작용 패턴을 알아보기 위해 다차원척도법을 실시하였다. 연구결과, 첫째, 좋아하는 교우관계는 파당 형성이 감소하고, 모든 구성원들의 교우관계가 연결되는 구조적 변화를 보였다. 둘째, 싫어하는 교우관계는 소수 구성원들의 매개효과를 통해 모든 구성원들이 연결되는 구조에서 특정 소수 구성원들에게만 집중되는 단절현상이 나타남으로써 교우관계가 긍정적으로 변화되었다. 셋째, 대부분의 구성원들에게서 교우관계 노드 간 연결이 3개 이상이면서 방향성이 존재하는 강한 결속을 보이는 것으로 나타났다. 넷째, 방과 후 모바일 네트워크를 활용한 운동 및 음식조절 행동 상호작용 효과는 교우관계 변화와 유사한 패턴이 나타났다. Physical activities are theorized to develop and maintain friendships. The purpose of this study was to investigate the change in friendship of students who participated in school-based health-related fitness program in women`s high school. Participants were seventeen female high school students(≥ BMI 25). Study used pretestposttest design. The program runs for 110 minutes daily(before- & after-school, lunch period) during school days, and performed for 9 weeks. Data were collected using Name Generator Question and mobile network. Data were analyzed through social network analysis technique such as centrality and components analysis. Also, multidimensional scaling analysis was performed to find out interaction pattern of mobile network communication. The results of this study showed that: (1) all students developed more friendship indicating decrease of clique (2) there were stronger friendship after the program (3) friendship structure was very similar to mobile communication pattern.

The measuring apparatus such as heat meter is legally obliged to be installed and used for heat rating for each dwelling in centralized residential buildings in Korea. Heat meters with mechanical working parts such as impeller, at present widely used in residential buildings in Korea, have caused some critical troubles, such as errors of impeller working, the insensitive response at low flow rate range and so on. For the sake of solving these problems, an electromagnetic heat meter was developed recently in KICT. A field test at the residential building complex were carried out in the present study to verify the influences on reliability of newly developed heat meters in various field conditions such as the pressure in pipe works, temperature and humidity of the installed circumstances, etc.. As results we found that heat meters installed H-apartment houses having been operated confidently in winter season. 2.4~13.8% of heating energy saving was also achieved through the mind inspiration.

This paper investigates the short- and long-run relationship among Korean, U.S. and Japanese construction indices. We conducted the Johansen`s cointegration test on the hypotheses that the construction indices of three countries are related in the long-run as well as in the short-run. The test results show that there exists no long-run relationship among three countries` construction indices. In addition, the cointegrating relation did not exist for three countries` stock market indices and five major Korean construction firms. It turned out that the U.S. indices Granger-causes Japanese and Korean indices. This finding implies that there may exist international diversification benefit ghrough forming a portfolio from these indices.

장기간의 규칙적인 배트민턴운동이 중년여성의 혈압, 심폐기능 및 혈중 지질에 미치는 영향

The purpose of this study was to investigate the effect of long-term regular badminton exercise on the blood pressure, cardiopulmonary functions and blood lipids in the middle-aged women. The 14 women aged 40s were selected as subjects. They were divided into exercise group and non-exercise group. The first group was 7 women who have been played badminton more than 5 times a week, more than 2hours a day, and during 5 years or more, and the second one was also 7 middle-aged women who were healthy but have never worked regular exercise. Between exercise group and non-exercise group, SBP, DBP, HRrest, VO2max, TC, TG, HDL-C, LDL-C, and TC/HDL-C were compared and analyzed. The conclusions of the study were as follows ; 1. The differences of the blood pressures between exercise group and non-exercise group were not significant and they were all normal levels in both groups. 2. In the cardiopulmonary functions HRrest was significantly lower, but VO2max was higher in exercise group than non-exercise group. 3. In the blood lipids TC, TG, LDL-C and TC/HDL-C were significantly lower, but HDL-C was higher in exercise group than non-exercise group. It is concluded that there were significant differences in the cardiopulmonary functions and blood lipids except blood pressure between exercise group and non-exercise group and the long-term badminton exercise was effective to improving some physiological benefits.

The purpose of this study was to compare the differences of cardiorespiratory functions and blood constituents in high school middle distance runners. Thirty nine high school male students composed with 13 excellent-runners, 13 good-runners and 13 non-runners were recruited for this study, The measurements were conducted on some factors of cardiorespiratory functions and blood constituents. The results of this study are as follows; 1. In the cardiorespiratory functions, excellent-runners group and the good-runners group were significantly lower than the non-runners group in HRrest and HRmax, but higher in VO₂max and exercise duration, and the excellent group was higher than the other two groups in AT and %VO₂max. 2. In the blood constituents, the excellent-runners group was significantly higher than the non-runners group in TC, TG and HDL-C and the excellent-runners group and non-runners group were higher than the good-runners group in Hct only among blood constituents. Therefore these results suggest that middle distance running performance is based on many factors and especially it is required to improve VO₂max AT and %VO₂max in cardiorespiratory functions, and HDL-C and Hct in blood constituents.
