건설R&D기술 표준화 특성 및 활성화 방안 도출에 관한 연구
이교선,윤원건,김경주,진경호,Lee, Kyo-Sun,Yun, Won Gun,Kim, Kyong Ju,Chin, Kyung-Ho 대한토목학회 2015 대한토목학회논문집 Vol.35 No.6
Recently, there is a growing interest in technical standardization all over industry, it is very important for survival in the global market to secure standard patent in almost all of company. Technology in construction industry is essential for quality of people's life and have large impact on national economy development. However, there is lack of investment and low interest in technical standardization in construction industry in comparison with another industries. Therefore this study aims at developing strategies for activating the standardization in construcion technology. Specially, this study carries market analysis and case study for domestic construction R&D Cases. Then, a structured survey and analysis is performed for standardization in construcion technology market to suggest alternative to secure national competitiveness.

According to the report from OECD, 80% of world trade quantity was influenced by standard, 50% of EU trade demand certification of forced standard. This leads to develop standard connected with R&D in most country and company worldwide. Recently, Technical standards have advantage of reduction of production cost and market dominating power. Standardization of construction technology has very important role that ouput of R&D refer to KS, national construction standards and it activates in the market. However, domestic construction research related to effectiveness of standadization fall short of expectation in comparison with manufacturing industry. This study present criteria that can analyze the performance and effectiveness in construction R&D project connected with standardization. And it applied domestic R&D cases (finished from 2000 to 2009), analyzes ouput of standadization and economic effect to verify the value of construcion technology standardization.

The Korean economic crisis hit badly the local construction industry, especially during the year of the 1998 when the country took the IMF bailout proframme. Under the poor business environment, such as reduction of construction investment, financial difficulty from high interest rate, and increasing bankruptcies, restructuring measures were repuired for survival of the industry. It is obvious the restructuring process is essential for the future business success. regardless of the financial crisis. With this background, this research aims the contribute to improved construction management structure and strengthened international competitiveness of the industry through the cost reduction and productivity enhancement, by analysising and proposing and optimal level of the manpower structure of construction management organization With the subject of 24 construction fields of apartment houses in the capital region as of January 1, 1999, constructed by OO company having leaded the construction industry of the country so far now, the researcher performed the on the spot survey regarding the organization/manpower structure and construction contract amount.

It was few to the integrated information classification system In domestic construction. Furthermore, it became considerable obstacles to hamper the increase of national competitiveness as well the hoarding of information and overlapped investment. The standardization of information classification is also necessary prior to the Computer-Integrated Construction, CALS(Continuous Acquisition & Life-cycle Support/Electronic Commerce) in construction, EVMS(Earned Value Management System) and the various projects which manipulate construction information. Therefore, this report suggests the development direction and application proposal of Integrated Construction Information Classification.

Milling Cutter Selection in Machining Center Using AHP
Kyo-Sun Lee(이교선),Soo-Yong Park(박수용),Dong-Hyung Lee(이동형) 한국산업경영시스템학회 2017 한국산업경영시스템학회지 Vol.40 No.4
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.

The Ministry of Construction and Transportation(MOCT) announced the General Policy for Effective Implementation of Public Construction Projects(the Policy) in 1999. Fifty two regulations were amended to embody the Policy between 1999 to 2001 Then MOCT performed the analysis to show the quantitative performance of the Policy. However, there has been no effort to evaluate the degree of implementation and effectiveness of the Policy so far. Therefore, this paper was initiated to perform the survey on industry's perceptions, implementation degree, effectiveness, and satisfaction of the Policy. The result shows that most policies were implemented in the construction industry but some policies were little adopted. Therefore, this paper proposes to update the Policy based on the survey results to effectively implement public sector projects.

엔지니어링의 비용은 공사비의 $3{\~}5{\%}$ 차지하나, 최종 사업목적물의 성능이 결정되는 단계인 만큼 사업초기단계에서 엔지니어링의 역할은 중요하다고 할 수 있다. 그러나, 국내 설계기술력을 선진국과 비교할 때, 계획단계 및 기본 실시설계, 시공단계는 각각 $63\%$, $66\%$, $73\%$로써, 사업초기단계로 갈수록 선진국의 기술수준보다 낙후되어 있다. 특히, 국내 설계기술력은 정부 및 업체의 기술개발에 대한 인식부족과 불확실한 결과 등의 이유로 선진국에 비해 크게 낙후되어 있는 실정이다. 그 결과 우리나라의 엔지니어링 분야의 해외진출 실적은 매우 미미하며, 국내 대형국책건설사업에 선진외국의 유사기술을 반복적으로 도입하고서도 고유기술화 시키지 못하고 있다. 이에 따라 사업초기단계에 필요한 기획 및 설계기술을 향상시킴으로 국민에게 안전하고 편리한 고품질의 생활기반을 제공하고, 나아가 해외시장에 진출하여 우리나라의 특화된 엔지니어링 기술을 수출해야 할 시점이다. 따라서, 본 고에서는 시장개방 및 세계의 통합화 추세 등 급속한 경제환경 변화에 대처하기 위하여 설계분야의 기술경쟁력 강화방안을 제시하고자 한다.
