        김원필(Kim, Won-Pill) 대한건축학회 2021 대한건축학회논문집 Vol.37 No.2

        Crime prevention through environmental design has been major issues in educational institution among public facilities. It is clear that securing students’ safety and prevention from the victimization of vulnerable students is important to attain educational goals and to provide diverse extra-curriculum activities for students. Further, campus dormitory is a focal area for students to experience social interaction between many students from diverse cultural background, thus leading personal growth and increasing the degree of satisfaction with college life. The purpose of this study intended to examine the effects of CPTED elements on the facilitation of students’ social interaction through the survey of students living in dormitory. Review of literature illuminated that defensible space, natural surveillance, social control, and criminal justice were important measures to deter any possible crime. A chi-square analysis found that social interaction and CPTED were statistically significant on personal characteristics. Correlation analysis and ANOVA confirmed that the degree of CPTED influenced on the level of social interaction among students living in dormitory; As the satisfaction with CPTED increases, the degree of social interaction rises at positive linear direction. Further the study reported that role of CCTV is a prime element for the facilitation of social interaction. An IPA also demonstrated that securing safety in night walking around dormitory environment and role of CCTV were the most urgent improvement items needed. Finally the study suggests that more careful design details and guidelines in design stage be explored in relation with major theoretical findings, even though research limitation exists from limited survey samples and target population.

      • RC 구조에 있어 TOP-DOWN 공법선정시 시공 효율성 제고를 위한 최적공법 선정에 관한 연구

        심재규 ( Jae Gyoo Shim ),김원필 ( Won Pill Kim ) 한국지역사회발전학회(구 한국지역사회개발학회) 2012 地域社會開發硏究 Vol.37 No.2

        본 연구는 최근 도심지 대심도 건축공사가 활발히 진해되면서 TOP-DOWN 공법이 확대·적용 되어가는 과정에서 나타나는 문제점들에 대해 최근 TOP-DOWN 공법 적용현장 등을 중심으로 적용시점과 적용요인에 대한 사례분석을 현장 방문과 현장 소장과의 구두 통화를 통하여 분석하고 향후에 TOP-DOWN 적용 현장에서 최적이 공법을 적용하고 아울러 시공의 효율성을 제고시키기 위한 방법들을 제시하는데 있다. 본 연구결과, 현재 약 19가지 TOP-DOWN 방식들이 개발·적용되고 있는데 초기 설계단계나 단순 영업에 의한 공법 적용은 발주처나 시공사들에 대해 경제성과 시공성 등에 손실을 초래하고 있음이 밝혀졌다. 따라서 중요한 사항은 공법의 적용이 설계단계에서 보다는 현장에서 발주처나 시공사가 지반상태, 흙막이 벽체공사, 골조구조, 경제성, 공기단축, 시공성, 안전성, 작업환경 등의 현장여건 적용요인들을 규정하고 우선순위를 고려하여 종합적으로 분석·적용이 필요한 것으로 분석되었다. 또한 R.C. 구조에 있어서 TOP-DOWN 공법 확대 적용을 위하여 관련 공정과의 연계를 통한 공사원가 절감, 시공성 개선, 제도적 보완 등에 지속적인 연구가 필요하다. This study intended to propose optimum Top-down method and efficient building construction method through site visits and interview with project manager for the analysis of top-down application in brisk urban building construction. Among 19 top-down methods, the analysis indicated that from the aspect of building construction and economy, technological application by initial design phase and simple business did impact on building construction firms. Therefore, the study contended that the application of top-down should be made based on the specified priorities of ground condition, structure, economy, shortening of project progress, building construction, safety, and working site condition in the important construction phase, rather than design phase. In conclusion, for the wide application of Top-down in R.C structure, it is necessary to do continuous research on cost down of construction costs, improvement of building construction, and implementation of system in relation with working schedule.

      • 수도권 노후 단독주택지 주거만족도조사 -성남시 소재 다중, 다가구를 중심으로-

        정욱수 ( Wook Soo Jung ),김원필 ( Won Pill Kim ) 한국지역사회발전학회 2012 地域社會開發硏究 Vol.37 No.1

        성남시는 서울시의 주택난을 해결하기 위해 1968년 경기도 양주군 중부면 지구 일단의 주택지 경영사업을 계기로 농촌 지역에서 도시로의 급속한 변화가 이루어진 곳이다. 본 연구의 목적은 이 지역의 주거 만족도를 조사하고 발전전략을 제안하는데 있다. 선행연구에 의하면 노후된 단독주택의 두 타입의 개발방법(철거 후 재개발과 재생개발방식)이 있다. 본 연구의 결과에 의하면 철거 후 재개발은 낙후된 단독주택지에서는 효과적인 방법이 되지 못하는 것으로 나타났다. 또한 철거 후 재개발 방법은 거주자들의 라이프스타일에 혼돈을 주어 재입주율이 10%이하로 나타났다. 단독주택지의 자체평가를 위해서는 건축법과 같은 법적인 검토가 필요하다. 단독주택은 기본적으로 개인적 취향에 의해서 계획된다. 그러나 다가구의 경우 대여나 판매 목적으로 건립된다. 연구결과 몇몇 활용할만한 내용들을 발견하였다. 인터뷰에서는 수입, 교육, 가족상황, 주택타입, 주택규모 분야를 조사하였다. 결론은 철거 후 재개발방식보다 재생개발방식이 낳은 것으로 나타났다. Seongnam city experienced a rapid changes in terms of the environment from its agricultural settings to city ones after the housing project in the Jungbu-nyon, Gwanju-gun in Gyunggi province area was managed in 1968. The project was promoted in an attempt to solve the chronic housing shortage in Seoul Metropolitan area in 1960s. The purpose of this study is to examine residential satisfaction with certain area and to suggest development strategy. Research findings noted that demolish and redevelopment was not considered as an effective solution for deteriorated single-family housing. The results of survey found some useful information on real estate contracts. In conclusion, restorative development is considered to be better for future urban redevelopment that method of demolish and revelopment based on the opinions of the author and realtors who have more that 30 years of experiences.

      • 右心房璧 移植에 關한 實驗的 硏究

        金源弼 中央醫學社 1967 中央醫學 Vol.13 No.5

        Macroscopic and histological studies were done on the canine right atrial patch grafts. Fresh autogenous and alcohol prserved homologous pericardium, dacron, and compressed. ivalon sponge patches were grafted into the right atrium to expand the atrial cavity. One, two, three, and four months specimens were obtained from each patch group off long term survivors. . Macroscopic findings: Among twenty long-term survivors an .organized thrombose was found on the intimal surface of the homologous pericarduim and decron patch, which were one month old. In one month old specimens, intimal surfaces were ragged and rough, while after two months every specimen showed smooth and glittering endocardial surface except homologous pericardiums. There was no evidence of aneurysmal dilatation of thee grafts. Shrinkage of the graft was almost absent in ivalon and remakeble in the homologous pericardium group. Microscopically: . One month group showed mainly neutrophile polymorphnuclear leucocyte infiltration, indicating acute inflammatory processes. . Two to three months old groups of the specimens showed subsiding acute inflammatory signs and repairing processes with marked small round cell infiltration, fibroblast, and fibrous connective tissue proliferation in and around the patches. In four months specimens fibrous connective tissue capsules were incorporated into the hosts’ myocardium firmly, and in most of them endothelialization of the intimal surfaces of these connective tissue capsules were noted. Among these four kinds of patch groups dacron showed the most and autogenous pericardium the least severe tissue reactions. In this right atrial patch graft experiment it was shown that the grafts healed satisfactorily in four months.
