The concept of sustainable development in rural area, which is focused on both preservation of nature and human's amenity, has been common paradigm. The purpose of this study is to suggest the development directions for the environmentally friendly rural house. The planning items for developing sustainable rural house were selected through literature survey, case study, and their adaptation evaluation. The establishment of principles and the evaluation of planning items were analyzed by a survey to experts. The results are as follows : 1) It is showed that sustainability evaluation of rural village is rated as above the moderate degree, but rural house is rated as 3.4(average score). Especially, there were lowly evaluated the utility, material, structure and inner environment in rural house. 2) It is revealed that 76.7% of planning items are located in both the upper left and upper right hand quadrant of the action grid, which is drawn by the importance-performance analysis(IPA). And any item is not found in the lower right hand quadrant(Possible Overkill). 3) Two basic principles and eight optional principles we identified by analysis of factor and regression. The rural zone is identified as major effective element for applying planning items into the rural house development. So it is desirable to apply the items differently by the rural zone type. 4) In view of sustainable development, it is desirable for rural village to have about 50 houses, and for rural house to have $155{\sim}180$ pyung(坪) as lot size, 30% as ratio of building, and 60% as building volume.

We present domestic efforts for superconducting fault current limiter (SFCL) application in the Korea Electric Power Corporation (KEPCO) grid and pending points at issue. KEPCO's decision to upgrade the 154 kV/22.9 kV main transformer from 60 MVA to 100 MVA cast a problem of high fault current in the 22.9 kV distribution lines. The grid planners supported adopting an SFCL to control the fault current. This environment friendly to SFCL application must be highly dependent upon the successful development of SFCL having specifications that domestic utility required. The required conditions are (1) small size of not greater than twice of 22.9 kV gas insulated switch-gear (GIS), (2) sustainability of current limitation without the line breaking by circuit breakers (CB) for maximum 1.5 seconds. Also, optionally, recommended is (3) the reclosing capability. Conventional resistive SFCLs do not meet (1) $\sim$ (3) all together. A hybrid SFCL is an excellent solution to meet the conditions. The hybrid SFCL consists of HTS SFCL components for fault detection and line commutation, a fast switch (FS) to break the primary path, and a limiter. This characteristic structure not only enables excellent current limiting performances and the reclosing capability, but also allows drastic reduction of HTS volume and small size of the cryostat, resulting in economic feasibility and compactness of the equipment. External current limiter also enables long term limitation since it is far less sensitive to heat generation than HTS. Semi-active operation is another advantage of the hybrid structure. We will discuss more pending points at issues such as maintenance-free long term operation, small size to accommodate the in-house substation, passive and active control, back-up plans, diagnosis, and so on.

IPCC는 국가별 온실가스 배출량이 얼마나 확실한 값인가를 보여줄 수 있는 불확도를 함께 보고하도록 규정하고 있다. 그렇지만 한국 정부는 IPCC 기본값을 그대로 적용하고 있는 수준에 불과하며, 그나마도 결측된 값들이 있어서 전체적인 불확도를 산정하지 못한 채 항목별 불확도만을 나열하고 있을 뿐이다. 이에 본 논문에서는 국가 온실가스 배출량의 85.3%를 차지하는 에너지분야를 대상으로 Tier 1 수준의 에러전파방법을 이용해서 온실가스 인벤토리의 불확도를 추정하고 있다. 분석결과 국내 에너지분야 온실가스 배출량의 불확도는 3.4%였으며, 이는 핀란드와 유사한 수치인 것으로 밝혀졌다. 그렇지만 온실가스별로는 이산화탄소의 불확도가 2.7%에 불과했지만, 메탄은 116%, 아산화질소는 473%에 달할 정도로 차이가 큰 것으로 나타났다. 따라서 본 논문에서는 한국 정부가 에너지분야의 불확도를 낮추려면 이산화탄소 보다는 메탄과 아산화질소를 대상으로 활동도뿐만 아니라 배출계수의 개선이 필요하다는 정책적 함의가 제시될 수 있었다. 결론적으로는 IPCC 기본값 대신에 신뢰도 높은 한국 고유의 배출계수를 개발하는 작업이 필요함을 제안하고 있다.

Industrial Revolution is a concept and a development that has fundamentally changed our society and economy. Industry 4.0 focuses on the end-to-end digitization of all physical assets and integration into digital ecosystems with value chain partners. At present, we find ourselves at the beginning of this fourth stage, which is characterized by so-called "Cyber-Physical Systems". These systems are a consequence of the far-reaching integration of production, sustainability and customer-satisfaction forming the basis of intelligent network systems and processes. If South Korea ran toward global ICT with the advent of the Fourth Industrial Revolution, North Korea has adhered to a unique Juche science and technology. ICT in South Korea and North Korea seems very difficult to find common interests. However, as seen in the Internet and intranets, information and communication technology can find similarities in many areas than in general science and technology. There are many differences not only in the level of ICT and science and technology but also in the direction. And IT terminology and all technologies are also different. What are we preparing for the unification of North and South Korea? If we look at the science and technology sector at present, there seems to be no systematic preparation by the government. South Korea and North Korea need to be prepared for science and technology cooperation. First, it is necessary to understand the exact situation of North Korea's science and technology. In this study, we will perform research to establish mid and long term plans for revitalization of ICT cooperation between the two Koreas. In this study, we will determine the extent to which the two Koreas utilize ICT based on available ICT capabilities and technologies. To do this, we conducted research to measure and evaluate the ICT development index of North Korea using ICT international index.

This research is a literacy study regarding the implementation and management of the economic role of haria as a new strategy in overcoming the problem of the global financial crisis that has hit the middle of the COVID-19 pandemic. The research method comes from previous studies to compare the capitalist, socialist, and sharia economic systems. In response to various economic uncertainties, both internal and external, the ability to seize opportunities and transform has become the key to economic resilience. Islamic economics can be an alternative in responding to the dynamics of the global and national economy. Several things need to be taken into consideration in fulfilling the sharia economy and the primary strategy chosen must come from the inputs given by the stakeholders, including business actors, associations, regulators as well as experts, and academicians. The primary strategy in implementing the sharia economy also requires the support of various parties in order to develop sustainability. Strengthening regulation and governance is one of the fundamental factors. Optimization of the sharia economy based social sector such as Zakat, Infaq, Sadaqah, and Waqaf can be optimized both for collection and distribution so that the concept of sharing can certainly support the development and the economy both nationally and globally.

A railway station appears in the form of multi-use station building where cultural and commercial elements such as shopping and leisure are mixed, getting out of simple space configuration oriented to the space for station work, where a passenger stays for a little while. Now, a railway station is a place expanded to the inside of city, and builds a relationship with urban fabric, and therefore it should receive the social change in the time together with the surrounding infrastructure, and should inevitably form the urban environment. And it should become the 'Place' so as to be capable of playing a role of buffer and a role of regional gateway landmark by making users included in the inside through various uses with regard to the dispersed urban connection. Hence, this study is intended to examine the planning through the place branding of railway station. In the method of research, the characteristics that place branding had was investigated, and an analysis was made on the basis of 10 place branding strategic elements and 6 railway design guidelines. And it was intended to set a direction in which the existing place branding strategy could be applied to the railway station, and was intended to derive the place branding planning strategic elements of railway station. Hence, the planning can be classified into the following 5 kinds in connection with railway station. First, identity should be embodied through the strategy of constructing the symbolic image of railway station. Second, a role of mediating variously approaching flows in the city should be played. Third, the spatial layout of railway station, which can increase the efficiency of use, should be arranged. Fourth, special characteristics should be intensified through creative storytelling that stimulates emotion. Fifth, an organic change is gradually necessary for sustainability. These planning elements should be applied in harmonious combination. Therefore, a new railway station can be maded by building identity and placeness and by giving the value through these planning directions in the future.

The aim of this study is to analyze the effect of the growing activities of large purchasing enterprises on the trust of small and medium size contractors, which is mediated by 'purchase accompany activity'. This subject study includes the first and second contractor companies in Korea. The results of this study are as follow. First, the knowledge and cost price sharing activities of major purchase vendor with cooperative company had a positive effect on the trust of cooperative company, however this was not so with the information sharing activities in that case. Second, the trust of contractors on large purchasing enterprises was positively influenced by sharing activities with purchasing activities of major company. Third, the knowledge and cost price sharing activities of purchasing enterprise with contractors on the sharing activities were mediated by the trust of contracting company on the large purchase enterprise. According to this study, the mediated effect of trust relationship can influence a contracting company. Whereas preceding studies of sharing activities were conducted about unidirectional instruct of large purchase enterprises to small and medium size contracting companies, this study was conducted on bidirectional effects, which included knowledge, cost price, information sharing activities between contracting companies and large purchasing enterprises. Conclusively, this study showed the possibility of spreading cognitive and change about mutual benefits strategy between small and medium size contracting company and large purchasing enterprise.
