Standards are increasing of importance for New & Renewable energy. The rapid growth of production is one reason for this but standards are equally important in ensuring the quality and reliability of installed New & Renewable energy systems, which have a propound impact on acceptance of the technology in the expanding marketplace. Korea government (Korea Agency for Technology and Standards, KAIST)make and implement a five year plans for promotion of international standardization of this field from 2004. KATS leads the technology innovations and eventually increases the international competitiveness. Strategic collaboration with other countries is also strengthened through Korea's participation in international standards and conformity assessment system such as IECEE(IEC system for conformity and certification of electrical equipment). One of the major goals of the Plan is to facilitate trade between Korea and its trading partners by emphasizing harmonization of its national conformity assessment system with international norms.

Agricultural Technology Center is an education center to provide agriculturalists with information and technology related with agriculture. As domestic and international environment of agriculture and rural area is changing, functions and roles of Agricultural Technology Center are evolving according to stream of times. In 1995, a new urban and rural complex city was created for symbiotic relationship between city and rural area, As a result, user group of Agricultural Technology Center expanded to nonagriculturalists. Though the change of agricultural extension service is necessary to perform extended functions of rural area and to satisfy needs of new group of users, it is difficult to find enough studies on new functions and roles of Agricultural Technology Center to manage the service change. Therefore, this study is aimed to suggest new functions and roles of Agricultural Technology Center according to stream of times. This study were surveyed through questionnaire targeting users of Namyangju Agricultural Technology Center to compare user group awareness of Agricultural Technology Center in urban and rural complex city. According to this study result, while main purpose of agriculturalists' visiting at Agricultural Technology Center was participating in education programs related with agriculture. In contrast, nonagriculturalists usually visited the center for agricultural understanding, leisure activities, and children education, participating in field work programs. From the survey result of required functions of the center, it was revealed that nonagriculturalists expected urban agriculture, research for living improvement in rural area, adjustment education for returning farmer, and function of farming promotion, comparing agriculturalists. It is verified that this difference of user group awareness reflects the necessity that Agricultural Technology Center should change services and accept increasing use of nonagriculturalists with new functions and roles.

산업의 급격한 발전은 화석에너지의 고갈을 야기하였고, 이러한 이유로 화석연료를 대체하기 위한 에너지로 태양광에너지가 각광받기 시작하였다. 하지만 기술발전에 있어 전체적인 연구방향 및 향후 연구 방향에 대한 논의가 부족하였다. 이에 보다 효과적인 기술개발을 위해 특허 데이터와 논문 데이터를 활용하여 태양광 에너지의 기술 동향을 파악하고 논의를 진행하였다. 분석방법으로는 토픽 모델링과 텍스트 마이닝을 활용하여 1997년도부터 2015년까지의 데이터를 토대로 기술 동향과 연구의 방향성에 대하여 분석한다. LDA알고리즘을 통하여 토픽을 선정하고, 선정된 기술 범주에 포함된 키워드의 증가량을 살펴보고, 태양광 기술의 발전방향에 대하여 분석하였다. 태양광 발전 기술에 대한 연구는 꾸준히 진행될 것으로 예상되며, 특히 고효율화 및 고성능화 기술에 대하여 집중적으로 연구가 이루어질 것으로 분석된다. 향후 연구로는 해외의 특허데이터와 다양한 논문데이터를 추가하여 연구를 진행할 수 있을 것이다.

2D/1D coupling method is an important neutron transport calculation method due to its high accuracy and relatively low computation cost. However, 2D/1D coupling method may diverge especially in small axial mesh size. To analyze the convergence behavior of 2D/1D coupling method, a Fourier analysis for k-eigenvalue neutron transport problems is implemented. The analysis results present the divergence problem of 2D/1D coupling method in small axial mesh size. Several common attempts are made to solve the divergence problem, which are to increase the number of inner iterations of the 2D or 1D calculation, and two times 1D calculations per outer iteration. However, these attempts only could improve the convergence rate but cannot deal with the divergence problem of 2D/1D coupling method thoroughly. Moreover, the choice of axial solvers, such as DGFEM SN and traditional SN, and its effect on the convergence behavior are also discussed. The results show that the choice of axial solver is a key point for the convergence of 2D/1D method. The DGFEM SN based 2D/1D method could converge within a wide range of optical thickness region, which is superior to that of traditional SN method.

During the transformation of the agro-technology extension in rural China, many new Policy experiments are emerging to rebuild the lost linkages and to improve technology transfer with the system and among systems. Applying the Triple Helix Model of academy-agriculture-government relations, this paper explores a new pattern of technology transfer with the case of BaojiCity. The authors interpret the mechanism of 'Courtyards for Agro-experts', as well as the comparison between different types of courtyards. This article concludes that the Triple Helix in the agro-sector improves technology transfer and accelerates knowledge-based regional development. In the interest of farmers there should also be concern over reducing inequity the reform.

A construction temporary work is main process and importance trade section. A technology system of construction temporary has very low availability of field works and needs improvements in Korea as construction site has a quick response about new requirements. This study reviews literature researches and can verify that changes to a comprehensive technology system for construction site. In addition, it suggests a breakdown structure of new standards for temporary construction technology based on views of construction site managers. Meanwhile, temporary construction technology in Korea has changed with a specification of construction temporary work which had been revised in 2014. However, the revision is merely dividing the design and building off of construction temporary technology. It is lacking in many ways to change this in a new standard system for temporary construction technology. Henceforth, it needs to develop a standard system for temporary construction technology and a professional system that is appropriate for different purposes by detail trade sections.
