The arcades have been introduced for improving the environment of conventional markets but thermal discomfort could be occurred according to the characteristics of arcades. The purpose of this study was to compare with arcades of two traditional markets on indoor environment and find design elements that cause for built environment problems. To find the design elements which influence on the environment of the arcade, the wind tunnel tests in the arcades were conducted. The ventilation performance of the arcade was greatly influenced by the volume of arcade and the ventilation opening.

This study is to analyze the performance of a radiation-panel cooling system by means of CFD. In the first step of this study, the indoor thermal environment of the office space, which is air-conditioned by radiation-panel cooling system, is analyzed by field measurement and CFD (coupled simulation of convection and radiation). With comparing the both results, the validity of the CFD method is examined from the practical point of view. In the next step, the thermal environment of the model office space, which is cooled by tree types of HVAC system (radiation-panel cooling system, all-air cooling system, and hybrid air-cooling system of radiation-panel and natural ventilation), is analyzed by CFD. By installing a human model in the room model, the characteristics of heat transfer from human are also analyzed. In the case of the radiation-panel cooling system, operative temperature and MRT(Mean Radiation Temperature) of the human model become lower than those in all-air cooling system. The radiation-panel cooling system is concluded as very energy-efficient in this study.

A vairable gain amplifier(VGA) has been designed for 900 MHz-band applications. The VGA consist of three blocks; a control voltage feeding block, variable gain block, and constant gain block. The VGA has been simulated using the TSMC CMOS libraries. At 900 MHz, the maximum gain is 34.6 dB with an 1 - dB gain compression output power of 3 dBm. The gain control range is 30 dB from 3.8 dB to 34.6 dB by the control voltage from 0.9 to 3.0 V. The gain control sensitivity of the VGA is 70 mV/dB, which is larger than a thermal voltage (26 mV/dB at the room temperature) in order to be insensitive to temperature variation.

The purpose of this study is to examine the influence of family relation and emotional regulation on conflict resolution strategies in children's friendship which influences on children's social adaptation and development. Also, this study tests the independent effect of emotional regulation, find out the important of emotional regulation, and promotes its growth and change positively. Results of this study are as follows. First, there were some differences in the conflict resolution strategies according to child's personal factors (sex, number of sibling, birth other and household's monthly income). In the conflict resolution strategies, girls used more dominating strategy. Also it was shown that the more household's monthly income used the more compromising-integrating strategies. Second, in research of the effect of children's recognized family relation on conflict resolution strategies their friendship, cohesion, one of the family relation subscales, has a positive influence on conflict resolution strategies and especially it predicted compromising-integrating strategies the most significantly. Also, expressiveness influenced only compromising-integrating strategies and conflict subscale influenced only dominating strategies. Third, in research of the effect of children's emotional regulation on conflict resolution strategies in children's friendship, emotional regulation has a positive influence on conflict resolution strategies except for other-regulation that influence dominating strategies. Especially in the cases of each subscale, self-regulation influenced avoiding and dominating strategies more, and other-regulation influenced compromising-integrating and obliging strategies more. Fourth, in research of effect of children's recognized family relation and emotional regulation on conflict resolution strategies in children's friendship, emotional regulation without family relation showed as independent effect. Especially it predicted compromising-integration strategies, that is the most effective solution for conflict situation, the most significantly.

단순지지된 샌드위치슬래브교량의 파괴강도해석

한지웅,한봉구 서울産業大學校 2005 논문집 Vol.54 No.2

현재 복합재료분야의 기술은 나날이 발전되고 있는 상황이다. 복합재료로 만드는 여러 가지 산업시설물과 생활용품 등이 제작 또는 생산되고 있는 실정이다. 그러나 아직까지도 토목분야에서는 옛날의 구시대적인 재료인 콘크리트와 강재를 이용하여 건물 및 교량 등을 건설하고있다. 여기에는 여러 가지 문제점이 있지만 그 중에서 가장 크게 문제가 되는 것은 복합재료의 이론이 너무 복잡하고 힘들다는 점에 있다. 일반 기술자가 사용하기에는 너무 어렵다는 것이다. 본 논문에서는 토목기술자가 복합재료의 설계적 마인드를 가질 수 있게 함과 동시에 실무설계를 할 수 있게 하였으며, 복합재료로 이루어진 교량을 설계하기위하여, 단면은 가장 경제적이면서 응력에 유리한 폼코어 형태를 채택하였고, 응력을 산출함에 있어서는 유한차분법 프로그램을 이용하였으며, 프로그램의 정확도는 Navier의 해와 비교하여 정확도를 입증하였다.

정지웅,표내숙 부산대학교 과학교육연구소 2007 교사교육연구 Vol.46 No.2

This study purpose was to examine worries of high school players in the area of Busan & South Kyeongsang province while exercising. In order to conduct the study, sports games were divided into three categories; team sports, record-taking sports and weight sports. This research was based on questionnaires of 400 males and 200 females for team sports, 136 males and 80 females for record-taking sports and 92 males and 52 females for weight sports who had played games before. The findings of the study were as follow. First, exploratory factor analysis of high school players' worries. 8 factors has been drawn up from a total of 80 questions. The factors are worries about friend relationships, future, pressure from seniors, languor of exercise, weight, schoolwork, injuries and expectations from parent in order. The samples of the data on factor analysis were proven to be appropriate. Also they share common elements with Bartlett's standards which measure appropriateness. In order to test the validity of factors, expert's examination was conducted. Second, reliability analysis of worry factors. All factors were proven to be credible after being measured by reliability alpha to test credibility of factors. Third, difference analysis of worries between gender. It was found that females had higher perception of worries than males in all 6 factors except worries about future and expectations from parent. Forth, difference of factors by sports. It was found that worries about weight, expectations from parent and injuries were perceived higher in weight sports than in team sports and record-taking sports. 이 연구는 고등학교 운동선수들을 대상으로 운동과 학업을 병행해야 하는 청소년기 운동선수들이 느끼는 걱정거리를 탐색하여 선수들이 가지고 있는 걱정거리를 이해하고 운동 스트레스로 이어지는 것을 차단하고자 실시하였다. 이 연구의 목적은 현장에서 지도하는 지도자들이 보다 효율적으로 선수들의 경기력을 향상 시키는데 도움이 될 수 있는 자료로 활용하는데 있으며 연구결과, 첫째, 탐색적 요인분석 결과 총30문항에서 8개 요인이 형성되었고 요인구조는 친구교류걱정, 장래걱정, 선배압력, 운동무기력, 체중관리걱정, 학업걱정, 부상걱정, 부모기대걱정 순으로 나타났다. 요인분석에 대한 전체 자료의 표본 적합도는 양호한 것으로 나타났으며 요인분석의 적합성을 나타내는 Bartlett's 구형성 검정치도 요인분석에 적합한 공통요인이 존재하는 것으로 나타났다. 이상의 요인 구조를 이루고 있는 각 요인의 내용에 대해 전문가 검증을 실시함으로써 내용 타당도를 검증하였다. 둘째, 탐색된 요인에 대한 신뢰도를 알아보기 위하여 문항간의 내적 일치도 검증인 Cronbach's α 계수를 구한 결과 모든 요인이 신뢰성이 있는 것으로 나타났다. 셋째, 친구교류걱정, 선배압력, 운동무기력, 체중관리걱정, 학업걱정, 부상걱정 6개 요인에서 여학생이 남학생보다 걱정거리가 높게 지각되며 성별에 따른 차이가 나타났다. 넷째, 체중관리걱정, 부모기대걱정, 부상걱정 요인에서 체급종목이 단체종목, 기록종목보다 높게 지각되면서 종목별 차이가 나타났다.

Background and Objectives: The objective of this study was to obtain circumstances about violence providers and cause of the violence in emergency room. Materials and Methods: Reports were provided to emergency department doctors, nurses and emergency medical technicians working in Chosun University Hospital Emergency Center during the sixty days from 26 May 2003 to 24 July 2003. Report form consisted of the degree of violence, the reason for the violence, dermographic information about violence providers, outbreak time of violence and response of emergency personnels. Results: SixtyUeight case of violence in the emergency department were reported. Almost all of the violence was due to the male gender and high incidence in third and fourth decade. The violence occured mostly in the night shift. 55.9% of violence was done by patient and 41.2% was done by patient's guardians. The leading cause of violence were alcohol drunken and delay of laboratory test and treatment. Verbal abuse and threats were the most concern form of violence, Conclusion: It is necessary to solve the problems faced in the emergency department not only administrative and financial aid but also regular preventive education and further study.
