At this present, the world is in the era of digital and culture.Tourist resources through cultural infrastructure have been a crucial factor of a country's competitiveness. A Museum is tourism resource facility like one of core cultural infrastructures which provides experiential culture, history and tradition. The field of a planning and a design for a museum should be recognized like professional design industry.n Korea, the government has various laws and systems to support the design promotion policy but it is not sufficient. If you plan to extend the scope of the maintenance of law and institutions As today 'Exhibition Industry Development Act, which is responsible for maintenance, including a permanent exhibition area in the exhibition industry facilities will be efficient alternative. And also, it would like to analyze states of the orders in the exhibition design industry for past five years (2010 ~ 2014) and show the problems and alternatives. Exhibition business-related orders investigation into the recent five years to analyze and suggest improvements. In the delivery method it was found three types of goods, the services, the delivery method through the analysis of the enforcement order to the Corporation and that are mixed.If these alternatives has been reviewed and used for basic data to promote professional companies and designers for museums, it must be expected to be well worth a careful study.

사회서비스 분야는 이용자의 욕구 확대에 따라 사회서비스 공급체계 또한 급속한 변화를 보이고 있다. 전통적인 사회복지에서 서비스는 공공과 민간에 의해 제공된다면, 사회서비스는 영리와 비영리라는 새로운 구조가 혼합된다. 하지만, 이와 관련된 기초연구는 충분하지만 공급유형별 성과관련 연구는 매우 미약하다. 이러한 점을 고려하여, 사회서비스의 영리 조직과 비영리 조직의 성과평가에 대한 비교를 시도하였다. 관련 자료는 보건사회연구원의 사회서비스 수요 공급실태조사에 활용된 데이터를 사용하였으며, 대상은 가사간병서비스와 노인돌봄서비스로 한정을 하였다. 성과평가를 위한 방식은 재무관점의 가장 초보단계인 총수익에서 총지출을 제외한 순수익을 활용하였으며, 영리와 비영리조직에 대한 차이를 검증하였다. 사회서비스 조직의 지출의 연구결과를 보면, 영리조직은 인건비, 운영비, 시설비, 소모품비 등에서 비영리조직보다 지출 비용이 높게 나타났으며, 다만 사업비 부분과 기타 부분은 비영리 조직이 영리조직보다 높게 제시되었다. 이와 같은 점을 고려하면, 향후 전달체계의 변화와 함께 영리와 비영리의 공정한 경쟁을 위하여 영리조직을 위한 추가적인 지원방안이 필요함을 확인할 수 있었다.

The CNC machine tool field is showing a growing trend with the recent rapid development of manufacturing industries such as semiconductors, automobiles, medical devices, various inspection and test equipment, mechanical metal processing equipment, aircraft, shipbuilding and electronic equipment. However, small and medium-sized machining companies that use CNC machine tools are experiencing difficulties in increasingly intense competition. Especially, small companies which are receiving orders from 3rd or 4th venders are very difficult in business management. In recent years, company S experienced difficulty to make product quality and delivery time due to the ignorance of the processing method when manufacturing cooling plate jig made of SUS304 material used for cell phone liquid crystal glass processing. In order to solve these problems, we redesigned the process according to the size of our company and tried to manage all processes with quantified data. In the meantime, we have found that there is a need to improve the cutter process, which accounts for most of the machining process. Therefore, we have investigated the correlation between RPM and FEED of three cutters that have been used in the past. As a result, we found that it is the most urgent problem to solve the roughing process during the cutter operation which occupies more than 70% of the total machining. In order to shorten the machining time and improve the quality in machining of SUS304 cooling plate jig, we select the main factors such as price, tool life, maintenance cost, productivity, quality, RPM, and FEED and use AHP to find the most suitable milling cutter. We also tried to solve the problem of delivery, quality and production capacity which was a big problem of S company through experiment operation with selected cutter tool. As a result, the following conclusions were drawn. First, the most efficient of the three cutters currently available in the machining center has proven to be an M-cutter. Second, although one additional facility was required, it was possible to produce the existing facilities without additional investment by supplementing the lack of production capacity due to productivity improvement. Third, the Company's difficulties in delivery and capacity shortfalls have been resolved. Fourth, annual sales increased by KRW 109 million and profits increased by KRW 32 million annually. Fifth, it can confirm the usefulness of AHP method in corporate decision making and it can be utilized in various facility investment and process improvement in the future.

As one of the advanced design features of the APR1400, direct vessel injection (DVI) system is being considered instead of conventional cold leg injection (CLI) system. It is known that the DVI system greatly enhances the reliability of the emergency core cooling (ECC) system. However, there is still a dispute on its performance in terms of water delivery to the reactor core during the reflood phase of a large-break loss-of-coolant accident (LOCA). Thus, experimental validation is under progress. In this paper, test results of direct ECC bypass performed in the steam-water test facility tailed MIDAS (Multi-dimensional Investigation in Downcomer Annulus Simulation) are presented. The test condition is determined, based on the preliminary analysis of TRAC code, by applying the ‘modified linear scaling method’with the l/4.93 length scale . From the tests, ECC direct bypass fraction, steam condensation rate and information on the flow distribution in the upper annulus downcomer region are obtained.

This paper deals with the attrition rate of major facility such as a particular building that is one of the most important target in the war time. In order to estimate the attrition rate, we use JAWS, WinJMEM which are programed by JTCG/ME of AMSAA and spreadsheet package which is able to assist the limitation of those programs and calculate all the procedure of this computation. This method uses the effectiveness index(El) which indicates the numerical measure of the effectiveness of a given weapon of a given target. The range error probable(REP) and the deflection error probable(DEP) in the ground plane also should be used. Those mean the measure of delivery accuracy of the weapon system. In this paper, it is improved that the El can be obtained from the regression analysis using the weight of the warhead explosive as the independent variable. It implies that we are able to obtain the El and the conditional probability of damage of the enemy weapon. After that, the single-sortie probability of damage can be computed using WinJMEM or another assistant program such as the spreadsheet package which shows the result immediately.

Due to various project delivery methods and the complexity of construction projects in the construction industry, developing the framework of construction management for critical, highly complex projects in the construction industry has become problematic. Currently, a set of construction manuals play a pivotal role in planning and managing construction projects as subcontractors try to complete their scope of work according to the instructions of a general contractor. It is challenging for general contractors to write a construction management procedure manual to cover various types of project delivery methods and construction projects. In construction, the construction procedure manuals describe specific actions to be taken through the project. In reality a few contactors own such manuals and their construction schedules include more construction operation activities. Thus, it is hard to estimate the workload and productivity of construction managers because the manual and the schedule do not present the amount of management efforts required to complete a project. This paper proposes a framework to present construction management tasks according to project delivery methods which can be applied to various construction projects. Actions for management tasks were mapped and were integrated with construction activities throughout the project life cycle. The framework can then be used to give specific instructions to project participants, collect management actions, and replicate management actions throughout the project life cycle. The framework can also be can used to visualize complete construction project to analyze and manage construction management activities in each phase of a project in order to enhance productivity and efficiency. The studies of existing construction manuals were carried out to identify construction managers' responsibilities. An artificial intelligence program, CLIPS (C-Language Integrated Production System) was used to search for appropriate actions for impending tasks from a set of predefined actions to be performed for a given situation. The framework would significantly help construction managers to understand interrelations among management tasks or actions within a project. Furthermore, the framework can be embedded into Building Information Modeling (BIM) or Facility Management Systems (FMS) so that designers and constructors would execute constructability review before construction begins.
