  • A micro-grid (MG) is a new concept to aggregate distributed generations (DGs) and loads in a small area. The difference between MG and DG is that MG can supply power to loads even in islanding conditions. The magnitude of the fault current depending on interconnection between the MG and utility and the number of DGs in the MG. Therefore, the setting value of the OCR must be changed depending on operating conditions of the MG. This paper proposes the over-current relay considering operating conditions of the MG. In the proposed algorithm, the supervisory control and data acquisition decides the operating conditions of the MG and sends the proper setting values to each OCR. The performance of the algorithm was investigated in the case of the various operating conditions.

  • Vitamin E has been a generic term for all tocopherol and tocotrienol derivatives. The most active form of vitamin E isoforms in vivo is regarded to be $\alpha$-tocopherol which is the only form defined as vitamin E in the US Food and Nutrition Board, causing controversy over setting dietary reference intake (DRI) of vitamin E. However, most of the countries other than the US maintain the original concept that all isoforms are accepted as vitamin E but with different biopotency. The roles of the isoforms of vitamin E other than $\alpha$-tocopherol have received continuous attention. Among them those of $\gamma$-tocopherol and $\alpha$-tocotrienol have been most studied in comparison with $\alpha$-tocopherol, since $\gamma$-tocopherol comprises major form of vitamin E in many plant seeds and those of the both vitamin E have been implicated in unique physiological functions. This review summarizes findings that have led a better understanding of vitamin E absorption, transport, tissue storage and various functions common and specific to vitamin E isoforms focusing $\alpha$- and $\gamma$-tocopherol as well as tocotrienols. It is expected to help redefining vitamin E and setting its DRI for Koreans.

  • This study proposes an entrepreneurship education process for fashion product start-ups through rewards-based crowdfunding. It examines issues such as: the general concept of crowdfunding and the pros and cons of rewards-based crowdfunding, the detailed curriculum plans in a chronological order for the regular class development, and the presentation of a visual plan to show the whole process. An entrepreneurship education process is developed in 13 steps: research on crowdfunding market, prototype plan, prototype production, story development, visual contents development, rewards development, project evaluation, public schedule & service setting, period setting & start funding, community management (Q&A), funding ends & deposit, complete manufacturing & start delivering, and the final information disclosure & open the next project plan. This research is intended to investigate rewards-based crowdfunding as a new paradigm of entrepreneurship and apply entrepreneurship education in fashion product development. However, it is limited to studying the Wadiz crowdfunding platform in Korea. Therefore, we propose a case study on various crowdfunding platforms in Korea, a case study on entrepreneurial curriculum application, and a follow-up study on the possibility of entry into an overseas crowdfunding platform.

  • This study aims to establish a landscape plan that can preserve the identity of the region while meeting the unique functions related to land use of the Saemangeum agricultural land. In addition, it was intended to prepare a mid- to long-term landscape plan basic concept for the formation and management of the Saemangeum agricultural land landscape. Therefore, in this study, landscape management by type for processing/storage facilities, production/processing facilities, complex/sales facilities, and research/experimental facilities for facilities scheduled to move in after setting the direction and five strategies for landscape management considering the specificity of agricultural land direction was set. In addition, the landscape management direction for 6 common landscape elements such as buildings, open spaces, advertisements, colors, public facilities, and night scenery was also presented. In particular, Agroworks, Agro City, and Agro Town, which are important landscape areas, are landscape-focused management areas, and the landscape management direction for the area has been established. This study is considered to have great utility value when setting landscape standards for public or private buildings and infrastructure, development projects, etc. to be moved in prior to establishing a landscape plan for agricultural land. It is expected that it can be used as a basis for deliberation and review of the landscape standards derived from this study in the future landscape-related licensing for agricultural land.

  • The purpose of this is to understand the concept of Sacho on the basis of 'Sa-Sang philosophy(四象哲學)'. In oder to achieve this purpose, Sanjiao and Sacho were investigated, centering on the philophicalbasis, region. action. The conclusion would be summerized as follows. 1. Viewed in the light of a philosophical basis, Sanjiao is first recorded in Nae-Kyung(內經), a concept that Yin-Yang(陰陽), Oh-Hang(五行) in Nae-Kyung Medcine, the cosmos's order and it's moving rule could be directly applied to human body. On the contrary Sacho is a term first used by Lee Jae-Ma, a human-oriented concept that formed in Confucianism system. based on Sa-Sang type classifying in Sa-Sang Medicine. 2. Viewd in the light of a region, the upper part of Sacho is similar to the upper-jiao of Sanjiao, the mid-upper part of Sacha to the middle-jiao of Sanjiao, the mid-lower and the lower parts of Sacha to the lower-jiao of Sanjiao. But these regions are not equal to anatomical regions. Sanjiao and Sacha is similar concept from the view point of the upper and lower oder, but Sanjiao has only a concept of the upper and lower order, doesn't have a concept of the front and the rear, inside and outside. 3. Viewed in the light of a action, Sanjiao and Sacho is a similar concept from the view point of a large boundary in the life activity.Sanjiao explains the region of human body, setting imfortance on the viscera physiology, on the contrary Sacho explains the whole function of human body including one's heart's desire, physical constitution and the visceral physiolosy. 4. Viewed in the light of produsing-wasting activity. sanjiao and Sacho have both produsing action and wasting action. but Sacho has a more concrete concept of produsing action by using a term-Sa Hae(四海) 5. Viewed in the light of vital energy(氣)'s action, Sajiao give the first consideration to the rising and falling action of vital energy, on the contrary Sacho give the first consideration to the transversal circulation of vital energy and the deviation of it in each part. According to the above results, Sacho must be discussed separately from Sanjiao, it is recommended that further study is necessary to understand the concept of Sacho on the basis of Sa-Sang philosophy.

  • This study aims to suggest 'an eco-friendly residential housing design guideline as an elderly housing alternative' by mixing the concept of a 'senior citizen community' housing environment with the concept of an 'eco-friendly' housing environment, based on the directivity of an elderly housing alternative for surviving in a super-aged society and the directivity of a sustainable housing environment for providing against global warming. Basically, this study considered the directivity of 'an eco-friendly residential building as an elderly housing alternative' by analyzing housing environment elements and elements to be considered in an elderly housing environment and setting the directivity of an elderly housing environment, which reflects the change in the design paradigm. In relation to the concept of universal design, for considering the perspective of elderly users, existing elements were compared and major planning elements were applied to the scope of complex planning, communal space and housing unit space. In relation to the concept of eco-friendly design, also, a guideline was re-organized and planning elements were applied to each category by comparing domestic and foreign green building certification systems. Based on domestic and foreign authorized guidelines of universal design and green building certification systems, this study was focused on suggesting an eco-friendly residential housing design guideline as an elderly housing alternative to make users perceive the need for a specific indoor environment design guideline and system.

  • The Seoul Housing Corporation pronounced a design competition for Eunpyeng New Town District 2 in March of 2005. The authors collaborated on this design and won rot prize. Design guidelines of this competition were to make environmentally sustainable design, to develop as a resort site and cultural place for everyday life of residents, to link with green fabric of the district, and to elevate positive image and identity of Eunpyeng New Town district by creating a attractive landscape. The authors developed design concept and strategy within the guidelines and site conditions. The environmental setting of this site was characterized by mountain to the rear of the site with a stream passing through the district and the front of the site. This is the most important condition for the location principle of residence in Fung Shui theory. Therefore, the schema of the design was introduced by Fung Shui and Chi of place. To evolve design concept, we reinterpret the Fung Shui and Chi in the site combining with modem landscape design strategy, so that good place making could bring about well-being life of residents. By doing that, design concept of the proposal evolved as follows: 'fullness of comfortable life', 'adaptation of nature', 'inspiration of natural force'. This design approach is critical reevaluation of regional characters employing modem strategy. It is a conscious strategy of critical regionalism as distinguished from the traditional site oriented approach. The following are some of the major features in the design: green network and water recycle system in the site, promenade of forest with the experience nature, link to community core, theme gardens with plants having strong fragrances, terrace gardens with different level of housing type, playgrounds and resting places with many types, human scale facilities for residents.

  • This paper as the basic study aiming the establishment of nursing theory according to Korean culture, is made to reveal the types of recognition about concepts of health immanent in Korean who have the health view, completely mixed with traditional oriental medicine and Confucianism and Buddhism and Shamanism and european scientific medicine, etc. This paper is using the Q-method, which is greatly effective in measuring the individual subjectivity, to collect rightly the concepts of health of objects. This analysis shows us the 4 types of recognition about concepts of health immanent in Korean as follows. Type Ⅰ: modern self-searching type(現代的 自己 追求型), Type Ⅱ: nature-sharing type(自然 共有型), Type Ⅲ: meaning-intentional altruism(意味 指向的 他者 中心型), Type Ⅳ: oriental adaptational type(東洋的 順應型). The men belonging to type Ⅰ have positive and self-searching view of health. They are not only interpreting the concept of health scientifically, but also positively accepting the oriental concept of health. The men belonging to type Ⅱ have strong tendency of down-to-earth. They not only have the naturalistic view of health as Taoist, but also carry the weight in the family and neighbour and regard co-sharing as excellent virtue. The men belonging to type Ⅲ are positive altruists, pursuing the meaning of life and at the same time setting the importance to the good value system. Naturally they care more the family and neighbour than themselves. The men belonging to type Ⅳ have oriental view of the world characterized by nature-adaptation. They positively agree to the Shamanism, Buddhism, Confucianism and Oriental concept of health. In conclusion, in all types we can see that Korean understand the harmony of man and nature as fundamental principle of heath and carry the more importance to the mind(心) than body(身) and at the same time esteem more the family-centric, oriental and organic community than individual. All above facts is immersed in the concepts of health of Korean as a common denominator.
