Construction project manager's personal competency is required to implement a effective and efficient construction project for the successful construction project. Since, it depends on a role and responsibility by a position, the level of personal competency may different to be required. Thus, to comprehend the level of competency is important. At the same time, it is able to draw out what competency is not enough, through understanding the level of personal competency. To improve all personal competencies is required to devote resources, but it is impossible because of limited them. Therefore, it is important how choose more important competency for improvement. This paper drew the improvement priority of construction project manager's personal competency which has different, through analysis the level of required and possessing competency. For their proper priorities determination, priority index was suggested and compared with other index.

Construction manager's personal competency is very important for the successful implementation of a construction project. Required and possessing personal competency of construction manager is different according to position and duty. In this research, we used personal competency model which was presented in the preceding study for personal competency analysis of construction manager. This study was performed to analyze personal competency by position which is divided as three groups from position by roles. First, the required competency level of construction manager was analyzed by using analysis of variance(ANOVA) in each of the groups. Second, a comparative analysis was conducted between the required competency level and the possessing competency level in each of the groups by using t-test. As the results, we present target competencies which have to be improved.

Construction project manager’s personal competency is very important for the successful implementation of a construction project. In this research, we classified construction project manager’s competency into personal characteristic competency and interpersonal competency. Twenty-one personal characteristic competency items and eighteen interpersonal competency items were extracted from previous researches. Questionnaire survey result from one hundred fourteen respondents were analyzed to build a personal competency model of construction project managers. Through factor analysis process, four competency group having fourteen competency items were determined as the personal competency and three competency group having fourteen competency items were determined as the interpersonal competency.

새로운 진공상태에서의 고온초전도 현상과 반자성

이형락 ( Hyeong Rar Lee ) 경북대학교 과학교육연구소 1993 科學敎育硏究誌 Vol.17 No.-

전자와 홀 형태의 고온 초전도 현상을 설명하기 위해서 새롭게 고체내에서의 진공(ㅇ9ㅔ6)을 정의하였다. 새롭게 정의된 진공에서 Cu원자간의 Supere×change와 Carrier의 Hopping 파라미터를 Hubbard Hamiltonian을 사용하여 계산하였다. 쌍을 이루지 않은 Carrier들은 반자겅의 Background에 의해서 국소화되지만 Carrier가 쌍을 이룸으로서 CuO2 평면 내에서 자유로와질 수 있다. 결국 쌍을 이룬 Carrier가 에너지가 낮아지게 되면 그 에너지 Gap을 Carrier 쌍의 Hopping 에너지로부터 계산하였다.

Graphite Oxides as Effective Fire Retardants of Epoxy Resin

이유락,김순철,이형일,정한모,Anjanapura V. Raghu,Kakarla Raghava Reddy,김병규 한국고분자학회 2011 Macromolecular Research Vol.19 No.1

Graphite oxides (GOs) at various oxidation states were examined as fire retardants of epoxy resin. Excessive oxidation is detrimental to the fire retardant effect of GO because it generated a weak GO with reduced intumescent ability. GO manifested optimum fire retardant properties when it was properly oxidized due to the effective intumescence, demonstrating that intumescent GO needs to be strong enough to effectively push the epoxy resin matrix apart to cause efficient intumescence and generate a solid remnant char that acts as an efficient barrier. The fire retardant effect of GO was also reduced when a dispersion of GO in the epoxy resin was enhanced by sonication. This shows that the fine dispersion and disordering of layered structure of GO by the intercalation of epoxy molecules into the gallery of GO also reduced the intumescent ability, and the fire retardant effects of GO.

본 논문에서는 2차원에서의 전자 상태에 대한 분수양자화의 가능성을 제시한다. 여러겹의 평면으로 구성된 Riemann 표면을 제시하고 그 Riemann 표면에서의 경계 조건으로서부터 2차원 전자계의 각운동량은 유리수 양자화가 이루어 진다. 비압축 양자유체에 대한 파동함수와 양자유체의 결합 에너지, 기저상태 및 여기상태의 에너지에 대한 계산 결과는 분수 양자 홀 효과의 실험결과와 잘 일치함을 보인다.

PMIS의 품질이 프로젝트관리의 성공에 미치는 영향 분석

이슬기,이형락,유정호 한국건축시공학회 2010 한국건축시공학회지 Vol.10 No.6

As one of the key IT applications, the project management information system (PMIS) has played a significant role in construction management processes. This is because PMIS is an information system that gathers, integrates, and disseminates the output of project management processes among project participants, and is used to support all aspects of a project, from initiation through closing. This paper aims to identify the CSFs(Critical Success Factor) of Project Management and quality associated with Project Management Information System (PMIS) in construction projects, to analyze the Effect of PMIS quality on Project Management Success. The CSFs of Project Management and the quality components for PMIS are identified through a review of the literature, and consolidated through interviews with professionals in the construction industry. A questionnaire instrument was sent out to experienced users (Construction Manager and Constructor), and 253completed questionnaires were retrieved. To increase the applicability of the results, the respondents consisted of workers spread across various parts of the construction site. Using SPSS 12.0, the data was used to analyze the relationship between PMIS Quality and Project Management Success through multiple regression analysis. These findings help to clarify what the highly prioritized factors are, and could also be used as an assessment tool to evaluate the performance of PMIS and thus help to identify areas for improvement. 건설 PMIS(Project Management Information System,이하 PMIS)는 과거의 업무보조 수단에서 벗어나 프로젝트의성공을 위한 필수적인 도구 중의 하나로 인식되고 있다. 하지만 정보관리시스템 구축 목표와 전략 부재로 인해 투자비 규모 설정은 물론 파급영향에 대한 기대감 상실로 정보화 노력이 일시적 현상에 그치고 있다. 이는 정보화 투자 대비 효과에대한 검증이 부족하여 정보화를 추진하는데 있어 동기 부여가되지 못하기 때문이다. 따라서 본 연구에서는 PMIS의 품질요인과 프로젝트 관리의 성공 간에 영향관계를 파악하는 것이목적이다. 건설 프로젝트 관리의 성공요인, 정보시스템 품질평가 및성공모델 도출에 대한 기존 문헌고찰을 통해 프로젝트관리의성공과 PMIS의 품질을 측정하기 위한 평가항목을 구성하였으며 실제 PMIS의 사용자인 시공사, 사업관리자(Construction Manager, 이하 CM)를 대상으로 설문조사를 실시하였다. 이렇게 수집된 자료들로 통계프로그램인 SPSS 12.0을 활용하여다중회귀분석을 통해 건설 사업에서 PMIS의 품질요인과 프로젝트 관리의 성공간의 영향관계를 분석하고 시사점을 도출하였다.
