직무분석을 통한 건설기능공의 교육훈련방안에 대한 기초적 연구
정순오,천봉기 경복대학 2000 京福論叢 Vol.4 No.-
건축물의 품질은 기본적으로 시공단계에서 좌우되고 있다. 그러나, 기능공에게 요구되는 기술수준의 기준이 명확하게 규정되지 않았고, 기능공의 작업분석도 체계적으로 이루어 지지 않고 있다. 그리하여, 본 연구는 건축물 품질에 상당히 중요한 역할을 하는 기능공들의 교육ㆍ훈련방향을 제시할 직무분석 방법을 제안고자 한다. 본 연구의 주요 목적은 건설 기능공들의 합리적인 훈련방법에 대한 기초자료를 제공하는데 있다. 본 연구에서 직무분석은 시공단계의 품질에 상당히 많은 영향을 미치는 거푸집 기능공, 콘크리트 타설 기능공과 철근 기능공에게 초점을 맞추었다. The quality of Constructions have been managed primarily in constrution phase. However the standards of the skill level which is required to craftmen are not confirmed definitely and the analysis of works is not accomplished systematically. So, this paper propose the job analysis method which will present the direction of educationㆍtraining of craftmen who play a great deal of roles in constrution quality. The main objective of this study is to provide a fundermental data for the reasonable methods of the training of constrution skilled workers The job analysis in this paper is focused on the works of form, concrete and bar workers, which affect quite a lot in the quality of construction phase.

정순오 한국조경학회 1985 韓國造景學會誌 Vol.13 No.1
Korea needs proper and rational public policies on conservation and use of forest land and other natural resources because of the accelerating expansion of national land developments in recent years. Unfortunately, there is no systematic planning system to support the needs. Generally, forest land use planning needs suitability analysis based on efficient land classification system. The goal of this study was to classify a forest land using multivariate satistical methods. A case study was carried out in winter of 1983 on a mountainous area higher than 100m above sea level located at Mt. Kwanak in Anyang -city, Kyung-gi-do (province). The study area was 19.80 km$^2$wide and was divided into 1, 383 Operational Taxonomic Units (OTU's) by a 120m$\times$120m grid. Fourteen descriptors were identified and quantified for each OTU from existing national land data : elevation, slope, aspect, terrain form, geologic material, surface soil permeability, topsoil type, depth of the solum, soil acidity, forest cover type, stand size class, stand age class, stand density class, and simple forest soil capability class. For this study, a FORTRAN IV program was written for input and output map data, and the computer statistics packages, SPSS and BMD, were used to perform the multivariate statistical analysis. Fourteen variables were analyzed to investigate the characteristics of their fire quench distribution and to estimate the correlation coefficients among them. Principal component analysis was executed to find the dimensions of forest land characteristics, and factor scores were used for proper samples of OTU throughout the study area. In order to develop the classes of forest land classification based on 102 surrogates, cluster and discriminant analyses of principal descriptor variable matrix were undertaken. Results obtained through a series of multivariate statistical analyses were as follows ; 1) Principal component analysis was proved to be a useful tool for data selection and identification of principal descriptor variables which represented the characteristics of forest land and facilitated the selection of samples.

커튼월 Life Cycle Process의 효율성 향상을 위한 비효율 요인 밑 중요도 도출
정순오,김예상,윤수원,진상윤,Jung Soon-Oh,Kim Yea-Sang,Yoon Su-Won,Chin Sangyoon 한국건설관리학회 2005 건설관리 : 한국건설관리학회 학회지 Vol.6 No.4
커튼월은 최근에 고층 건축물에서 공기단축을 위해 가장 많이 활용되고 있는 외장 공법이며, 공사비와 공정관리 측면에서 주요 관리대상의 공종이다. 커튼월 프로세스의 효율적 관리는 전체 프로젝트의 성공적 수행을 위한 주요 대상으로 인식되고있다. 그러나 기존의 커튼월 공사 관리는 시공 단계 중심의 관리에 초점을 맞춤으로서, 공사 수행의 오류, 잘못된 작업으로 인한 재작업, 비효율적 정보관리로 인한 중복 $\cdot$오류 $\cdot$누락 등의 문제가 발생하고 있고, 전체 생애주기 관점에서 효율적 관리가 이루어 지지 못하고 있다. 따라서 본 연구는 커튼월 공사 전체 생애주기 프로세스를 분석하여, 프로세스의 효율성 향상을 위한 단계별 관리 포인트를 제시하는데 목적이 있다. 이를 위해 비효율 요인을 도요다 시스템의 무다(muda)방법으로 규명하고, 계층적 분석법(AHP)을 이용하여 비효율 요인의 중요도를 도출하였다. 그 결과 커튼월 생애주기 중에서 건축설계 단계에 가장 많은 비효율 요인이 발생되었고, 주요 세부요인으로는 설계변경 의사결정 지연 및 승인지연, 엔지니어링 능력부족, 발주자의 건축도면 승인지연 등으로 나타났다. Recently, a curtain wall construction is a exterior finishing components which is most used for shortening time in high-rise building as well as the class of key management factors in cost and schedule control. Also, it is recognized that an effective management for curtain wall process is a major subject to accomplish the project successfully. However, as the current management for curtain wall construction is focused on the construction stage, it makes problems such as errors in business performance, rework by mistakes and duplications, errors and omissions by ineffective information management and there has never been any efficient management from a view of the entire Curtain Wall Life-cycle process. Therefore, the aim of this study is to suggest a stage check point for process improvement in the curtain wall Life-cycle process through current curtain wall process analysis, and then to investigate the cause of waste factors using the Muda method from the Toyota Production System and extract the weighted effects of the waste factors using the analytical hierarchy process method. According to the result, Most of the inefficient factors happened in architectural design stage of the entire curtain wall Life-cycle process and my research identified that detail factors of them are a delay of decision making and an approval in changes, a deficit of engineering capacity and a delay of approval in architectural design drawings by owner, etc.
