박찬영,유승운,Park, Chan-Young,Yoo, Seung-Woon 대한토목학회 2014 대한토목학회논문집 Vol.34 No.6

최근 들어 탄소섬유 FRP가 보수/보강재로 많이 활용되고 있다. 본 연구에서는 탄소섬유 FRP 판을 영구 거푸집으로 활용하여 새로운 콘크리트 교량 바닥판 시스템을 개발하기 위하여 CFRP판과 고인성 섬유보강 콘크리트 사이의 부착성능에 대한 평가를 실시하였다. 현장타설 콘크리트와 CFRP 간에 부착을 높이기 위하여 시중에 유통되는 에폭시를 사용하여 규사를 부착하였다. 일반콘크리트의 부착응력은 2.11~5.43MPa으로 나타났고, 고인성 섬유보강 콘크리트인 DC1 (RF4000)과 DC2 (PP)의 부착응력은 각각 3.91~5.60MPa, 2.92~5.21MPa이며, DC3 (RF4000+RSC15)의 부착응력은 4.80~5.58MPa, DC4 (PP+RSC15)의 평균 부착응력은 5.57~5.89MPa으로 나타났다. Recently FRP of carbon fibers is utilized as a repairing and reinforcing material for concrete structures. In this study, the bond performance between CFRP planks and ductile fiber reinforced cementitious composites was evaluated in order to develop a new system of concrete bridge deck to take advantage of the FRP planks of carbon fiber using as a permanent formwork. In order to strengthen the bonding between the FRP and cast-in-place concrete, an epoxy resin circulated in the market generally was fitted with a silica sand. The bond stress of ordinary concrete appeared in 2.11~5.43MPa and the bond stress of ductile fiber reinforced cementitious composites DC1 (RF4000) and DC2 (PP) respectively were 3.91~5.60MPa, 2.92~5.21MPa and the average bond stress of DC3 (RF4000+RSC15) and DC4 (PP+RSC15) were 4.80~5.58MPa, 5.57~5.89MPa.

SOC 예산 부족과 불충분한 건설자금 문제 등으로 건설사의 체감경기가 악화되고 있다. 이러한 상황에서 건설 VE는 건설 수익향상을 통해 이러한 상황에 대처하는 수단이 될 수 있다. 본 연구는 Importance Performance Analysis를 실행하여 효과적인 시공VE의 전략을 수립하기 위한 건설사의 강점 항목과 약점 항목을 도출하였다. 건설사들은 건설VE에 대한 지원·협력·지식 등 12개 항목에서 강점을 지닌다. 반면, 'VE리더의 VE 경험', '상세비용 추정', '아이디어 생성·평가' 등은 약점이 있는 것으로 나타났다. 본 연구는 제도적 관점에서 VE 활성화에 중점을 두었던 기존 연구와 달리 건설기업 관점에서 효과적인 시공VE 수행을 위한 전략을 도출하였다는 점에서 의의가 있다. Shortage of SOC budget and inappropriate initial construction cost planning have worsened the economic sentiment of the construction firm. Construction VE can be one of the solutions for improving the profitability of construction projects. This study identifies the strong and weak points of construction firms for establishing the strategy of effective construction VE by using importance-performance analysis. As a result, construction firms have strong points on support, cooperation, and knowledge about construction VE, but have weak points on 'VE experience of VE leader', 'Detailed cost estimation', and 'Idea generation and evaluation'. This paper contributes to establishing the strategy of effective construction VE from the perspective of the construction firm, which is differentiated from previous studies that have focused on the institutional approach for construction VE.

플랜트 공사 모듈러 공법 적용 의사결정을 위한 연구 - 모듈러 공법의 장·단점 및 적용 장벽에 대한 고찰 -

박찬영,김현진,원진우,장우식,한승헌,Park, Chan-Young,Kim, Hyunjin,Won, Jin Woo,Jang, Woosik,Han, Seung-Heon 한국건설관리학회 2016 한국건설관리학회 논문집 Vol.17 No.4

최근 생산성 향상의 필요성과 함께 시장 환경 변화에 따른 극오지 및 격오지 공사 수행의 필요성으로 인하여 플랜트 프로젝트에서의 모듈러 공법 적용이 확대 추세에 있다. 그러나 모듈러에 대한 실질적인 이해부족과 관련 시스템의 부재로 실제 프로젝트의 모듈러 공법 적용은 어려운 상황이다. 따라서, 본 연구에서는 사업 초기단계에 프로젝트의 시공 방식(Stick-Built, Modular) 결정을 지원할 수 있는 의사결정 모델을 제시하고자 하였다. 이를 위해 모듈러 적용의 이점과 장벽에 대한 분석을 실시하였고, 프로젝트 및 모듈러 공법의 특성과 사업초기단계 가용데이터를 고려하여 총 6개의 모듈러 공법 의사결정인자를 이용하는 의사결정 지원 모델을 개발하였다. 본 연구에서 제시하고 있는 의사결정 모델은 사업 초기 단계에서 가지고 모듈러 적용 가능성을 1차적으로 평가하였다는 점에서 기획 단계에서 플랜트 프로젝트의 모듈러 공법 적용을 고려하는 하나의 도구로써 활용이 가능할 것이라판 단된다. Recently, The importance of modular construction method has increased by market environmental change. However, it's application in the actual project is restricted due to the lack of understanding of modularization and the absence of utilization system. To overcome this problem, this study propose the decision-making model for selecting modular or conventional (stick-built) construction method at early stage. First the needs of modular method in plant project is derived and the benefits and barriers of modular construction are analyzed through literature review. Based on this analysis, 6 decision-making factors covered project and modular characteristics are derived and the decision-making model is developed. Finally, 12 actual overseas project cases is evaluated by this model for verifying its applicability. This proposed model can provide the guideline to select the construction method in early stage for successful execution of plant project.

The purpose of this study is to correct the nodule abundance of FFG (Free Fall Grab) sampler on KODOS (Korea Deep Ocean Study) area in North-East Pacific Ocean. The image analysis of sea-floor photography was carried out for correcting the abundance of nodules, and the image enhancement techniques and edge detection method were used to discriminate between nodules and sediments. The trace of nodules on sediments was detected to reduce the fractionation effect in calculating the coverage of nodules. The three methods, using the coverage of nodules, using the volume density, and using corrected volume density, were utilized for the correction of the nodule abundance. The method using the coverage of nodules was more convenient and available for the correction of nodule abundance than the other two methods. The method using the corrected volume density had the highest confidence level compared with the other methods.

In order to utilize the data obtained during the deep-sea resources exploration program, the analysis of data structure and database were conducted to develop an appropriate data operating system called Deep-sea Database System. The Relation Data Base Management System, RDBMS, was chosen as a data managing system and the MS Access$^{TM}$ as a DB engine, and the MapInfo$^{TM}$ software as GIS tools. Problems in networking and security were detected and solved during the operation test. Accordingly, development of standardized operative procedure was proposed in obtaining raw data. This proposal will also be reflected in the subsequent phase of the deep-sea program. The Deep-sea Database System could be applied to the selection of potential mining sites and the estimation of economical efficiency over th KODOS (Korea Deep Ocean Study) region. It is also expected that this system might improve the efficiency of detail survey and help in the relinquishment process as a fulfillment of the obligation as a pioneer investor.

Anhidrotic ectodermal dysplasia is inherited as an X linked recessive trait. This disor der is characterized by hypotrichosis, hypodontia and hypohidrosis. The diagnosis is often delayed until the first or second year of life, after repeated episodes of potentially damaging high fever. In the newborn period, the diagnosis is more difficult, but early diagnosis is of importance in ensuring that the appropriate enivironment and medical measures be taken to avoid uncontrolled hyperthermia. We have experienced a case of anhidrotic ectoclermal dysplasia in an8-day-old male patient who showed charecteristic features including hypotrichosis, peeling or scaling of the skin, recurrent fever and a characteristic face. A skin biopsy from the right palm revealed no sweat gland strutures. A brief rview with related literature is also presented. (Korean J Dermatol 1997;35(5): 1005-1008)

박찬영,전효택,강정극,Park, Chan Young,Chon, Hyo Taek,Kang, Jung Keuk 대한자원환경지질학회 1996 자원환경지질 Vol.29 No.5

The purpose of this study is to develop geostatistical methods for selection of prospective areas of polymetallic nodule deposits in KODOS (Korea Deep Ocean Study) area of the North-East Pacific Ocean. In this study $110{\times}165$ grid system was used, and each node represents the center of an estimated block of $1km{\times}1km$. The ordinary kriging was applied to SeaBeam2000 data in order to evaluate the bathymetry. A structural analysis (variogram) of the bathymetry data was carried out for constructing digital terrain model (DTM) and the maximum slopes of the bathymetry were calculated by DTM data. The above method can be used to solve the problem that is resulted from the lack of theory of a change of support model for the maximum slope of the bathymetry. The ordinary kriging and the indicator kriging were used to evaluate the nodule abundance, and the different two kriging methods were compared to evaluate the accuracy for the estimation of the nodule abundance. It has been shown that indicator kriging was better estimation tool than the ordinary kriging. The overlay map is presented for the selection of potentially minable sites by combining the two indicator maps of the nodule abundance and the maximum slope of bathymetry. This overlay map could be utilized to establish follow-up survey and to investigate the potentially minable sites in the KODOS area.
