Owners' efforts to acquire Green building certification, which started in 2002, have been rapidly increasing since 2006. The causes of the increased owners' interests are due to various incentives, legal obligation, and purpose of advertising. As project owners generally are deficient in capabilities and knowledge on how to deal with administrative works on certification, they tend to fulfill the minimum requirements for certification. However, effective administration process need capabilities of identifying individual making decision point and review information. The implementation of green building certification system is expected to provide comfort to both occupants and potential users. Furthermore it contributes to reducing energy costs throughout the phase of O&M. In addition, technology innovation in green industry can be obtained. Therefore, this study is intended to support owners in order that they can clarify certification tasks and make a rational decision-making in time. For this purpose, first of all, the major decision points were selected as the gateways of green building certification process. And then management system based on IDEF3 modeling was developed for supporting owners'decision-making performance. This management system will improve owners'overall capacity in handling all the tasks regarding the certification of Green building.

A Study on the Design of Database to Improve the Capability of Managing Offshore Wind Power Plant
2010
As for the present wind power industry, most of the computerization for monitoring and control is based on the traditional development methodology, but it is necessary to improve SCADA system since it has a phenomenon of backlog accumulation in the applicable aspect of back-data as well as in the operational aspect in the future. Especially for a system like offshore wind power where a superintendent cannot reside, it is desirable to operate a remote control system. Therefore, it is essential to establish a monitoring system with appropriate control and monitoring inevitably premised on the integrity and independence of data. As a result, a study was carried out on the modeling of offshore wind power data-centered database. In this paper, a logical data modeling method was proposed and designed to establish the database of offshore wind power. In order for designing the logical data modeling of an offshore wind power system, this study carried out an analysis of design elements for the database of offshore wind power and described considerations and problems as well. Through a comparative analysis of the final database of the newly-designed offshore wind power system against the existing SCADA System, this study proposed a new direction to bring about progress toward a smart wind power system, showing a possibility of a service-oriented smart wind power system, such as future prediction, hindrance-cause examination and fault analyses, through the database integrating various control signals, geographical information and data about surrounding environments.
세부 공정별 CO 2 배출 분석 및 환경비용 원가배분을 위한 Activity-based LCA 모델의 도입 - 커튼월 공사를 중심으로
Korean Journal of Construction Engineering and Management, 2012
As worldwide efforts to reduce global warming gases, the construction Industry is endeavoring to diminish carbon dioxides emissions. Especially, by introducing the LCA methodology to the industry, A variety of related studies to measure the emission of carbon dioxides have been conducted. However, when the conventional LCA methodology is applied to the construction projects, some limitations have been reported. To overcome the restrictions derived from the industry characteristics, this research suggested the Activity-based LCA model by applying the Activitybased Costing (ABC), which breaks down the whole life cycles into more detailed stages. By implementing the newly developed model, forecasting accuracy of CO2 emission was elevated, and the critical control points on carbon dioxides were established. Through the case study of aluminium curtain-wall system, this research verified the usefulness of the Activity-based LCA.

Objective: to improve agricultural working environment using tools and equipments. Background: most existing tools currently used, in fact, are discrepant from human factor guidelines so that they are still exposed to the musculoskeletal disease. Method: the provided tools and equipments are mostly designed considering human factor engineering or usability engineering in a way to avoid musculoskeletal disease. Results: propose the top-down procedure and usability engineering steps to evaluate them for the system design suitability. Conclusion: apply them conveniently into rural environment to help farmers working environment.

Ministry of Land, Infrastructure and Transport (MOLIT) promote long-life housing to reduce social costs generated by poorly considered rebuilding and extend the lifespan of housing. Long-life housing has advantages of durability, floor plan variability, efficient maintenance and ease of remodeling because it is a beam-column structure building. However, long-life housing requires somewhat higher initial construction cost than wall type apartments. It makes increase of long-life housing more difficult. In this study, we compare between wall-type apartment and beamcolumn structure apartment from Life-Cycle Cost's viewpoint. As a result of the study, long-life housing incurs 18% higher initial cost than wall type apartment, but is 7% more economical than wall type apartment in terms of Life Cycle Cost. Therefore, it is shown that long-life housing could be a beneficial alternative to traditional wall type apartments.

The main purpose of this current study was to identify the structural relationships between the variables of team attachment, location-based service, and future fan behaviors by utilizing Technology Acceptance Model (TAM). Among the 10 KBO franchises, SK Wyverns and KT Wiz were qualified to have their own smart applications programs and the relevant infrastructure at their home venues. Thus, a total of 500 surveys were collected from SK Wyverns and KT Wiz games during September of 2019 and a total of 448 were used for data analysis after deleting 52 surveys due to the missing data. According to the results of a structural equation modeling, 12 positive (+) causality out of 14 hypotheses were confirmed that there must be causal relationships among the variables of location-based service at the smart stadium, TAM, fan attachment, and future fan behavior. It is hoped that this study can be contributing to the foundational developments of marketing strategies by adopting the new technological advancement in the Korean sport industry in the future.
A Case Study of Improving Agricultural Work Environment through Work Domain Analysis
2015
In order to improve the agricultural work environment, many efforts to reduce the hazard from musculoskeletal disorders in Korean pepper farming operation have been made in such a way to do human factors engineering approach and relevant education. Although the efforts showed some contributions to improve agricultural work environment, the output from the various studies are obviously not sustainable and the problems in performing the pepper work are not still occurred. This paper shows one of the trials to resolve the problems by means of introducing the systematic approach to analyze the work domain and tasks. In this study, the systematic analysis such as Work Domain Analysis show showed that it helped to improve agricultural work environment.
