가치공학(Value Engineering, 이하 VE라 함)은 생산성향상기법으로 알려져 왔으나, 건설 분야에서도 적용되어 지난 십여 년 이상의 기간 동안 선진외국뿐 아니라 국내의 여러 사례에서 이미 그 효과가 입증된 우수한 관리기법이다. 국내 VE는 지난 2005년 건설기술관리법(이하 '건기법') 시행령('설계의 경제성 등 검토'-건기법시행령 제 38조의 13)이 개정되어 총공사비가 100억원 이상인 건설공사로 확대 적용되고 있는 실정이다. 그러나 국내 시장에서의 VE는 그 이론과 적용에 있어 여러 차이를 보여 온 것이 사실이며, 이로 인해 VE의 확대와 보급에 걸림돌로 작용해 온 것도 부인할 수 없는 현실이다. 따라서 본 연구에서는 최근 설계VE 수행사례를 통하여, 그 문제점과 원인을 다각적으로 검토하고, 이에 대한 개선방안을 제시하여 설계VE의 성공적인 국내정착에 일조 하고자 한다.

An extreme value analysis of metocean data which include wave, wind, and current data is a prerequisite for the operation and survival of offshore structures. The purpose of this study was to provide information about the return wave, wind, and current values for the Barents Sea using extreme value analysis. Hindcast datasets of the Global Reanalysis of Ocean Waves 2012 (GROW2012) for a waves, winds and currents were obtained from the Oceanweather Inc. The Gumbel distribution, 2 and 3 parameters Weibull distributions and log-normal distribution were used for the extreme value analysis. The least square method was used to estimate the parameters for the extreme value distribution. The return values, including the significant wave height, spectral peak wave period, wind speed and current speed at surface, were calculated and it will be utilized to design offshore structures to be operated in the Barents Sea.

Many innovative management processes, which are also termed as best practices or value improving practice, have been proven to successfully improve the value of capital facility projects. With a lack of any guidance on how to implement the most suitable value management process for a particular project, the objective of this paper is to facilitate the VMP implementation. A CII (Construction Industry Institute)'s recent study, titled as 'Development of the Value Management Toolkit,' encompasses a comprehensive structure of value management and provides a new methodology in optimizing the implementation of the value management processes in order to leverage the unique project circumstances, such as project objectives, resource availability, and site limitations, etc. As a pioneering study, the findings contribute to the expedition of implementing value management processes in the industry and maximize the potential benefits in applying the most benefiical value management process for a particular capital facility project.

The result of management profits create to manufacturing activity. The gross sale profits must be maximum thraw spend of economic value. The profit maximum have to management based key value driver of manufacturing activity. The important factors of the study model are manufacturing value driver(MVD) and manufacturing value added(MVA). We show necessity of management based value by means of a case study.

It has been found that implementing the function analysis is very important in terms of accomplishing successful Value Engineering(VE), and the function definition is a basic activity at design VE phase. In spite of the importance, the real function analysis activities in the VE are not regard as consequence. In this regard, this paper attempts to use the campus mater plan to lead an effective function analysis. So, the purpose of this value engineering study is to provide the criteria to develop the campus mater plan. This value engineering study used as a guide for the standardization of the campus mater plan. In addition, broader application is possible through the analysis throughout the different ways of the project.

Highly advanced technologies are being adopted into the domestic construction industry in accordance with rapidly changing global construction industry in the 21st century. Value Engineering methodologies have often been discussed but not yet settled in the country. This research, therefore, aims to provide a useful guide to utilizing design Value Engineering in Build Transfer Lease. 1. Questionnaires had been conducted, answered by those in the field. 2. Questionnaires were in regard to the obstacles in the application of design Value Engineering and activation schemes. 3. Five standards were provided to be chosen according to the degree of influence from each factor, whose answers were technically analyzed by a statistical program afterward. 4. Four obstacles classified in this method were approached systematically to analyze the problems. 5. Efficient Activation schemes have been suggested after various analyses in a variety of aspects.

This study aimed to identify the causal relationships among self-regulated learning strategy, problem solving efficacy, task value and learning outcome, and mediation effect of self-regulated learning strategy in engineering capstone design course. The data were collected from 363 university students who enrolled in capstone design courses and analyzed using structural equation modeling method. The results were: first, problem-solving efficacy and task value exerted significant effects on self-regulated learning strategy. Second, self-regulated learning strategy exerted significant effects on learning outcome, but problem-solving efficacy and task value did not. Third, problem-solving efficacy and task value showed significant indirect effects on learning outcome, which confirmed that self-regulated learning strategy fully mediated between two exogenous variables and learning outcome.

Interference occurs by signals received from directions that were different from the signals of the users in a mobile communication system. Various studies have been undertaken, including diversity, equalizer, etc., in order to reduce interference. In this study, the weighted value of the array antenna was obtained to improve signal-to-noise ratio. The weighted value was obtained as an eigen value and an eigen vector by using the correlation coefficient of the signal. The weighted value obtained was then applied to the CDMA system to increase system performance and capacity. Both QPSK and OQPSK modulation systems were applied to analyze performance.

Since its introduction in Korea, design VE has widely been used as a means to enhance values in the construction industry. However, a greater emphasis is still placed on cost reduction in approach attitudes and performance evaluations on the implementation of design VE. In this regard, this study presented a performance evaluation method for cost, function, and value of VE proposals. Numerical criteria on the increase and decrease of cost and function that can classify the value enhancement type of VE proposals were proposed based on the performance evaluation method. It is expected that the use of numerical criteria for the type classification of VE proposal, and cost and performance evaluation method proposed in this study will make it possible to conduct a clear and more intuitive evaluation of VE proposal. However, it is appropriate to use the numerical criteria as a guideline to apply the new performance evaluation method for VE proposals. Therefore, it is necessary to conduct a statistical analysis with a wider range of users after the repeated application of the findings of this study, and thus to carry out research for presenting the numerical criteria for various types of users.

Infrastructure is provided to the user through long-term project period and large-scale working expenses. Existing facilities are getting old as time goes by. Accordingly, proper maintenance is required and generally more maintenance cost than initial invested cost is needed during life cycle. Therefore, a specific plan that just increases the value of facilities is required by evaluating performance of facilities and inputting minimum maintenance cost. Value engineering that increases the value of object by systemically analyzing Life Cycle Costs and function is actively promoted at the design phase of construction. These efforts can increase the performance of facilities at the maintenance phase of infrastructure. This study is to search how to evaluate the performance of Roadway by utilizing function analysis, as a core part of VE in the maintenance phase. In order to this a new evaluation criteria were proposed by adding an evaluation items to the existing criteria through the research of old documents, status of roadway maintenance and function analysis of VE. The results of this study may promote the effective performance evaluation to determine a resolution of roadway congestion in future. A succeeding study using the proposed evaluation criteria will be required.
