해외 건설 프로젝트의 수주 물량은 2001년 이후 지속적으로 증가하여 2010년에는 전체 건설 프로젝트 수주 물량의 44.5%를 차지하고 있다. 해외건설 프로젝트는 프로젝트의 성패에 영향을 미치는 환경적 요소가 국내의 경우보다 다양하며 이에 따라 리스크 관리는 더욱 복잡해지고 있다. 현재까지 해외 건설 프로젝트의 리스크 관리에 관한 연구는 특정 지역 혹은 프로젝트의 발생 가능한 리스크 요인을 도출하고 이에 대한 관리 방안을 제시하는 연구가 주를 이루어 왔으나, 최근 환율 변동성의 확대로 인한 환 리스크의 중요성 및 관리기법에 관한 연구는 전무한 실정이다. 따라서 본 연구에서는 환율 변동 및 환리스크 관리 옵션(통화선도, 통화스왑, 이자율 스왑)에 따른 최근 6년간 국내 주요 건설사별 손익현황 분석 결과 및 통계 기법을 활용하여 건설사로 하여금 환리스크 선호도에 따라 해외건설 프로젝트의 환리스크를 효과적으로 관리해 나갈 수 있도록 하는 의사결정 지원 모델을 제시하고자 한다. 본 연구를 통해 제시된 환리스크 관리 의사결정 지원 모델 및 방법론은 건설사 등 해외 건설 프로젝트 수행주체가 환리스크를 사전에 예측하고 대응해 나감에 있어 주요 의사소통의 도구로써 적극 활용될 수 있을 것으로 기대된다.

$^1H-^{15}N$ heteronuclear dipolar coupling solid-state NMR experiments on lipid bilayer or bicelle samples are very useful for the structural studies of membrane proteins. However, to study these biological samples using solid-state NMR, a specific probe with high efficiency and high capability is required. In this paper, we describe the optimized design, construction, and efficiency of a 400 MHz wide-bore $^1H-^{15}N$ solid-state NMR probe with 5-mm solenoidal rf coil for high power, multi-pulse sequence experiments, such as 2D PISEMA or 2D SAMMY.

In Korea, smoke control measures through NFSC 501 are proposed to reduce human casualties caused by smoke in the event of a fire. However, as a result of investigating and analyzing domestic and foreign standards, it was found that domestic regulations do not set fire source, but simply set smoke emissions by floor area or height of smoke boundary. Foreign regulations set fire source. Therefore, it is judged that it is necessary to review whether the current domestic regulations can be applied in the event of an actual building fire. So, this paper aims to identify the differences in domestic and foreign standards through investigation and analysis of related standards for fire zone smoke control system in each country and use them as basic data to improve the performance of zone smoke control system.

국내 건설재해는 타 산업에 비하여 높은 수준이며, 안전관리활동도 시공단계에 국한되어 수행되고 있다. 하지만 일부 선진국에서는 건설현장 작업자들의 안전을 위해 안전관리활동을 사업초기부터 수행하여 재해발생의 소지를 사전에 회피, 차단 최소화하는 Safety Through Design에 관한 연구가 진행되고 있다. 이들 연구는 주로 발주자, 설계자의 안전책임과 역할에 초점을 두고 있다. 우리의 경우에도 국내 건설환경에 적합한 발주자, 설계자의 안전책임과 역할을 도출하고, 이를 근거로 사전예방적인 안전관리체계의 구축이 절실히 필요한 실정이다. 따라서 국내 건설사업의 효율적 안전관리를 위한 발주자, 설계자의 안전책임과 역할을 문헌연구와 설문조사에 근거하여 제시하였다.

The importantce of a development of competitiveness in domestic construction industry is growing as some of domestic construction markets is scheduled to open to foreign competing firms with higher level of construction technology and management. A national level of competitiveness in domestic construction industry and firms are partially, but significantly, affected by a technology level and a characteristics of production pattern. The purpose of the study is mainly to analyze and identify a technology level, production pattern and a development stage of R&D activities of domestic construction industry and firms. Based on these findings the study draws on a concluding remarks and derives technology policy implications. Results of analysis in the study impliy that (1) competitiveness of domestic construction firms(industry) in terms of technology level is relatively weak as compare to that of advanced foreign competing firms, (2) degrees of substitution of capital for labor are seemed to be relatively high, (3) R&D (investment) activities of domestic construction firms are generally spread out in forms of import, adjustment and betterment, and (4) only a small number of big domestic construction firms are seemed to afford to R&D investment for research facilities and equipments, but not enough for higher level of R&D man-power. The study suggests that technology policy for construction industry should be based on a fundamental policy directions. For example the increase in size and heightened quality level of R&D man-power should be placed in a top priority in policy agenda. Sound and specific policy items should be developed for planning and design, and maintenace and inspection technology in order to lead domestic industry to compete with foreign firms with full strength.

Nowadays, many construction engineering and technology enterprises are evolving to find that prosperity is driven and inspired by an open economy with dynamic markets and fierce multifaceted competition. Besides brand and product uniqueness, the ability to quickly provide customers with quotes are matters of concern. Such a requirement for prompt cost estimation of construction investment projects with the use of a construction price index poses a significant challenge to contractors. This is because the nature of the construction industry is shaped by changes in domestic and foreign economic factors, socio-financial issues, and is under the influence of various micro and macro factors. This paper presents a fuzzy decision-making approach for calculating critical factors that affect the construction price index. A qualitative approach was implemented based on in-depth interviews of experts in the construction industry in Vietnam. A synthetic comparison matrix was calculated using Buckley approach. The CoA approach was applied to defuzzified the fuzzy weights of factors that affect the construction price index. The research results show that the top five critical factors affecting the construction price index in Vietnam are (1) consumer price index, (2) gross domestic product, (3) basic interest rate, (4) foreign exchange rate, and (5) total export and import.

This research aims to investigate the standards and the performances of domestic and foreign windows for and apartment house and to present fundamental data for selecting the optimum window at the step of designing an apartment house. To compare the performances of domestic and foreign windows it is selected 5 major window companies in and 3 major window companies in Japan, and investigated window structure, material, type of opening and closing, window glass and the performances of windows for an apartment house-closing and opening force, repeated closing and opening, thermal resistance, sound transmission loss, air tightness, water tightness, wind resistance. The result of a comparative analysis show that the average thermal resistance of Korean window is higher than Japan's but the average sound transmission loss and water tightness of Korean window is lower than Japan's and the rest of the performances is similar.
