        李完熙 春川敎育大學 1985 論文集 Vol.25 No.-

        I studies for the 100r3 running ability of the students in the High School. This study is purposed on the Surveying of the factors to be needed for the inprovement on the running record and on the materials which can be used in the fields of education, Two hundred and forty three students(boys and girls in the all grades of C. boys highschool and C. girls high school in chun cheon.) served as assubjects. They were tested and analyged during septemter, 17-22, 1984. The results are as follows ; As shown in the above 1. The boy-students were faster than the girls in average running records in each section without relating to their ages. 2. The boy-students speed average also faster than the girls in each section. 3. The total numbers of the step3 for the boys were less frequency than for girls in each section without relating to their ages. 4. The average distance per step of the boys lager than of the girls in each section without relating to their ages. 5. The speed maintenance rate of the girls, except the case of 18 years, was higher than of the boys. 6. The speed deceleration rate of the girls, except the case of 18 year3, was lower than of the boys. 7. The speed acceleration rate of the boys higher than of the girls without relating to their ages.

      • 지역특성에 따른 국민학교 육상경기의 지도실태에 관한 분석연구 : 강원도내 국민학교를 중심으로 Centering around the primary schools in Kang Won Do province

        이완희 春川敎育大學 1989 論文集 Vol.29 No.-

        Conclusion and suggestion : This study as been conducted through the writer's visits to 87 primary schools in Kangwon-do province and through guestionaire on teaching field and track and raising to players from those schools. The schools were divided into 5 groups consisting of 15 schools in urban areas, 13 schools in agricultural areas, 13 schools in mining areas, 19 schools in reaoterural areas, 21 schools in areas adjacent to DMZ. the results of the writer's results of the writer's analysis are : 1. The general results teaching of field events showed more difficulty than that of track events regasdless of areas. 2. The teaching of track events showed difficulty in the order of hurdle races, long distance races, short distance races, middle distance races, and relay races. 3. The teaching of field events showed the most difficulty in high jump events. 4. The problems in teaching field and track events arise grom insuffgicient teaching methods, facilities, and sporting goods. 5. The most necessary facilities and sporting goods in teaching field and track were : 66.67% in high jump, 32.18% in track and straight line track, which are basic. The most serious areas are mining areas, remote rural areas, and areas adjacent to DMZ. 6. The normal operation of field and track events was not available in 89.66% the schools regardless of areas. 7. According to the regional conditions, the problems arise from these factors : in the problems of teaching field and track, urban areas suffer from large classes, agricultural areas from shortage of leaders, and inzmining areas, remote rural areas and areas adjacent to DMZ. 8. 87.36% of field and track umpires and leaders had no experience of participating in workshops. 9. In some schools field and track players were selected through races in schools grounds and teachers recommendations regardless of areas. 10. The responses from the parents of field and track players were generally netgative : urban areas showed 93.33% while mining areas 46.15%. 11. The problams in teaching and raising field and track players arose from these : urban areas suffered from limited ground space because of other events and parents' opposition, agricultural areas from insufficient player resource and budget, miming areas from pollution and freguent pupil transference, and remote rural areas and areas adjacent of DMZ from long cold winter and geavy fall of snow and limited training hours because of short shining hours. There are suggested : Field and track events which are basic and compulsory in physical education become unpopular events, that they are neglected by both pupils and parents. It is suggested that (1) these problems arising from regional conditions he solved immediately, (2) positive public relation be inplemented, (3) development and spread of audio-vidual aids suitable for teaching and developing field and track events he fulfilled, (4) appropriate workshops for in-service teachers he conducted.

        지역사회의 집합효능감이 범죄피해에 미치는 영향

        이완희,이미정 한국범죄심리학회 2019 한국범죄심리연구 Vol.15 No.4

        In a macro perspective, the relationship between the environment and crime has long been of great interest, and it is constantly being argued that crime victimization is not just an individual phenomenon but a result of the surrounding environment. Therefore, the purpose of this study is to explain the relationship of collective efficacy that is explained to affect crime victimization was analyzed through path analysis on the effect of the surrounding environment on crime victimization. Especially, this study examined the impact on the surrounding environment on crime victimization using ‘the National Crime Victimization Survey 2016 data’, which was investigated by the Korean Institute of Criminology. As a result of using the path analysis, individual-level variables and the environmental factors have a direct influence on the criminal victimization. Besides, the collective efficacy was found to the relationship between the environment and the formal social control was shown to be weak, showing the opposite result. However, the main variables of this study, collective efficacy, and formal social control did not appear to affect the criminal victimization, as opposed to previous studies. 거시적인 관점에서 지역과 범죄와의 관계는 오랫동안 많은 관심을 받아왔으며 범죄피해가 단순히 개인적인 요인에 의해 발생되는 현상이 아니라 주변 환경에 따른 결과라는 주장도 끊임없이 나오고 있다. 따라서 이 연구는 지역수준에서 범죄피해에 영향을 미치는 것으로 거론되는 집합효능감(collective efficacy)의 관계를 설명하는데 그 목적이 있다. 이를 위해, 주변환경이 범죄피해에 미치는 영향을 검증하기 위해 한국형사정책연구원에서 조사한 「한국범죄피해조사 2016」 자료를 사용하여경로분석(path analysis)을 실시하였다. 그 결과, 개인수준의 변수와 주변환경 요인은 피해경험에 직접적인 영향을 주는 것으로 나타났다. 또한 주변환경이 안 좋을수록 집합효능감은 높아지는 반면, 공식통제는 약해지는 것으로 나타나 상반된 결과를 보여주고 있다. 하지만, 이 연구의 주요 변인인 집합효능감과 공식통제는 일반적인 연구와는 반대로 피해경험에 영향을 미치지 않는 것으로 나타났다.

        데스크탑 가상화에서 HDFS를 이용한 서비스 제공시간 개선 연구

        이완희,이봉환,Lee, Wan-Hee,Lee, Bong-Hwan 한국정보통신학회 2012 한국정보통신학회논문지 Vol.16 No.5

        기존의 PC 기반의 데스크탑 환경은 보안, 이동성, 업그레이드 비용 감소 등의 장점으로 인하여 서버 기반의 가상데스크탑 환경으로 바뀌고 있다. 본 논문에서는 오픈 소스 기반의 클라우드 컴퓨팅 플랫폼과 하이퍼바이저를 이용한 데스크탑 가상화 시스템을 구축하여 이를 대학의 컴퓨터 실습실에 적용하였으며, 가상화 서비스 제공시간을 개선하기 위하여 HDFS를 이용한 해결 방법을 제안하였다. 또한, HDFS를 사용하여 데스크탑 가상화 서비스에 필요한 이미지 관리 구조를 설계하고 구현하였으며, 이를 실제 PC 30대를 운영하는 실습실에 적용하여 구축비용, 전원절약율, 라이센스 비용 절감율 및 관리 비용 등 네 가지 측면에서 기존시스템과 비교하였다. 실험 결과 HDFS를 이용하였을 경우 데스크탑 가상화를 서비스하기 위한 이미지 전송시간을 대폭 줄일 수 있었다. The current PC-based desktop environment is being converted into server-based virtual desktop environment due to security, mobility, and low upgrade cost. In this paper, a desktop virtualization system is implemented using an open source-based cloud computing platform and hypervisor. The implemented system is applied to the virtualziation of computer in university. In order to reduce the image transfer time, we propose a solution using HDFS. In addition, an image management structure needed for desktop virtualization is designed and implemented, and applied to a real computer lab which accommodates 30 PCs. The performance of the proposed system is evaluated in various aspects including implementation cost, power saving rate, reduction rate of license cost, and management cost. The experimental results showed that the proposed system considerably reduced the image transfer time for desktop service.
