This study contemplates the utopian landscape recognized by the scholars with twenty three pieces of 'travel record'. Consequently, five key words - Mureungdowon(武陵桃源), Byeolcheonji(別天地), Dongcheon(洞天), Chonghakdong, Eungeoji(hermitage) - are chosen for comprehending the utopia and their landscape characteristics are organised as follows. Mureungdowon in Jirisan Mountain which the scholars dreamed of is a flatland with the full energy for local vegetation and domestic animals in the mysterious and deep gorge. This utopia eventually reflects the rural landscape. Byeolcheonji is a utopia combining the concept of a fairyland and beautiful scenery. The scholars also used the term 'Dongcheon' for naming the enclosed landform which is suitable for seclusion and defining the some areas of beautiful scenery. Cheonghakdong, which is set only in Jirisan Mountain, has been formed by the stone scenery of gorges and Buril waterfalls around the whole area of Burilam Hermitage, the vegetation scenery of pine trees and bamboos with the legend of Choi Chiwon and his engraved inscription on a rock. Adding to the utopia passed down, the scholars perceived the village with geographical features with back to the mountain and facing the water, the river practising the trade, the flatland enclosed by bamboo forests, the vegetation mainly consisting of fruit trees and beautiful scenery as the utopia realized on earth. It is equivalent to the world of human beings laboring appropriately and living in Mother Nature. As mentioned above, this study has significance for apprehending the relevance between the culture of strolling in the mountains by the scholars of Joseon Dynasty and the fairyland and explaining the various traditional utopias from the inherited concepts from China to the naturalized realistic utopia.

This study was performed to encapsulate low molecular weight marine collagen and ${\gamma}$-aminobutyric acid (GABA)-producing lactic acid bacteria to inhibit degradation and improve survival rate during exposure to adverse conditions of the gastro-intestinal tract. Calcium-alginate method was used for the manufacture of a double-layered coated capsule. The inner core material was composed of collagen and lactic acid bacteria, and the coating materials were alginate and chitosan. The sizes and shapes of the double-coated capsule were affected mainly by centrifuge speed and pH. Manufactured capsules were observed with a scanning electron microscope and by confocal laser scanning microscopy to confirm the micromorphological changes of capsules and bacterial cells. As a result, double-layered coated capsules were not degraded at pH 1.2, whereas degradation occurred at pH 7.4. In addition, GABA and collagen were maintained in stable state at pH 1.2. Therefore, double-layered coated capsules developed in this study would not be degraded in the stomach and could be stably delivered to the small intestine to benefit intestinal and dermatic health.

${\gamma}$-aminobutyric acid (GABA) is a non-proteinogenic amino acid biosynthesized through decarboxylation of L-glutamic acid by glutamic acid decarboxylase. GABA is believed to play a role in defense against stress in plants. In humans, it is known as one of the major inhibitory neurotransmitters in the central nervous system, exerting anti-hypertensive and anti-diabetic effects. In this report, we wanted to enhance the GABA production from the barley leaf and corn silk by culturing them with lactic acid bacteria (LAB). The barley leaf and corn silk were mixed with various weight combinations and were fermented with Lactobacillus plantarum in an incubator at $30^{\circ}C$ for 48 h. After extracting the fermented mixture with hot water, we evaluated the GABA production by thin layer chromatography and GABase assay. We found that the fermented mixture of the barley leaf and corn silk in a nine to one ratio contained a higher level of GABA than other ratios, meaning that the intermixture and fermentation technique was effective in increasing the GABA content. We also tested several biological activities of the fermented extracts and found that the extracts of the fermented mixture showed improved antioxidant activities than the non-fermented extracts and no indication of cytotoxicity. These results suggest that our approach on combining the barley leaf and corn silk and its fermentation with LAB could lead to the possibility of the development of functional foods with high levels of GABA content and improved biological activities.

This contribution studied constructional intentions, ideas, thought and aesthetic consciousness of Joseon Royal Tombs regarding its location, spatial organization and elements. A literature investigation and a field study have been carried out, and the royal tombs of the Goryeo Dynasty and the Shilla Dynasty also have been studied to look for the its origins. The outcomes are as follows. The tomb's system of Joseon Royal Tombs inherited the King Gongmin's Tomb of the Goryeo Dynasty of Buddhism, but they have their own characteristics in a spatial organization and elements involved in Confucianism, Taoism, not only Buddhism. In the aspect of location, Joseon Royal Tombs followed the Feng-shu geometric principle to find a land that have a mountain in the back, and a river in the front. Spatial plan was carried out with Confucianism to apply the order of rank. Confucianism, Taoism, and Buddhism are shown with the elements such as architecture, landscape architecture, stone objects, and historical forest being connected each other. Especially, constructional intentions, ideas, thought and aesthetic consciousness are connected with the people in Joseon Royal Tombs through the ritual ceremony of Confucianism.

In order to investigate the diverse physicochemical changes that occurred in traditional Korean pottery during its production, including before and after firing, this study produced six replicas of a celadon maebyeong inlaid with cloud-and-crane designs, respectively corresponding to the process of shaping, carving, inlaying designs, first firing, glazing and second firing, respectively. It then conducted a scientific study of these six replicas and analyzed their images through high-resolution three-dimensional transmission imaging. The materials used for the replicas show different mineral phases and even colors depending on the components of each material. For example, black inlay with a high content of iron oxide (Fe₂O₃) shows dark colors and white inlay with a high alumina (Al₂O₃) content appears white. Physicochemical properties such as chromaticity and magnetic susceptibility and major components of the replicas were confirmed by the differences in the density in the computed tomography (CT) images. The characteristics of fired products such as fine structure, absorption ratio, apparent porosity, and other characteristics of the major mineral components were identified by the presence of pores and the formation of cracks inside the replicas in the image analysis.

Korean traditional music has been a process art which has been changed and re-created by musicians to mirror the musical aesthetics of contemporary people. Form court music, which has tried to keep the "authentic" form as much as possible, to folk music, which is closely associated to the people's life style, traditional music has expressed the life of the Korean people. From the early 20th century, traditional music faced a totally new music culture due to the Japanese annexation and rapid westernization. A new music network was established by modern theater and broadcast system. Many gayageum (12-stringed zither) masters were able to develop their own music in this new music culture. Female musicians came to exist because of a new music education system, called gwonbeon (school for female entertainers). Due to the rapid westernization, traditional music was becoming 'extinct'. The government's new system of Intangible Cultural Heritage tried to preserve traditional culture. Traditional music came to revive but became fossilized in order to preserve the 'archetype'. The so-called Living Human Treasures took power and became a social problem. The modern school education system was one of major factors for promotion of traditional music. However, it became one of main reasons for musicians to lose their musical creativity. Today, many performers and composers try to make a new composition and renovated musical instruments to suit the contemporary musical aesthetics.

식품자판기에 대한 미생물 기준이 마련되었다. 식품의약품안전청은 식품자판기 다류 커피 음료류에 대한 미생물기준을 담은 "식품의 기준 및 규격"를 일부 개정 고시했다. 이 기준이 마련된 것은 청결상태 등 위생관리가 불량하여 지속적으로 문제가 되고 있는 식품자동판매기 음료 등에 대해 효율적인 관리를 위한 기준이 필요하다는 판단 때문이다. 식품자판기 다류 커피 음료류에 적용되는 세균기준은 3,000/mL 이하(다만, 유가공품, 유산균, 발효제품 및 가열하지 아니한 과일 채소류음료가 함유된 경우는 제외)이어야 하며, 대장균은 음성이어야 한다. 이외 살모넬라(Salmonella spp.), 황색포도상구균(Staphylococcus aureus), 장염비브리오균(Vibrio parahaemolyticus), 클로스트리디움 퍼프린젠스(Clostridium perfringens), 리스테리아 모노사이토제네스(Listeria monocytogenes), 대장균 O157:H7(Escherichia coli O157:H7), 캠필로박터 제주니(Campylobacter jejuni), 여시니아 엔테로콜리티카(Yersinia enterocolitica) 등의 식중독균이 검출되어서는 아니 된다. 또한 가공식품에서 많이 검출되는 바실러스 세레우스(Bacillus cereus)는 g 당 1,000 이하(단 멸균제품은 음성이어야한다)이어야한다. 이번 미생물기준의 마련은 앞으로 법정기준을 위반시 처벌대상이 된다는 점에서 유의해야할 사항이다. 이전까지는 식품자판기에 대한 미생물기준이 마련이 되어 있지 않기 때문에 마땅한 법적인 처벌 기준이 없었던 게 사실이다. 따라서 자판기 운영업체에서는 보다 철저한 위생관리가 요구되고 있다. 위생점검에서 미생물 기준을 지키지 않은 지판기에 대해서는 법적 처벌 근거가 마련이 되는 만큼 식품자판기 위생성 향상에 만전을 기해야 할 것이다. 6월 16일 개정고시된 미생물기준은 7월 1일부터 적용된다.

The registered-properties guideline was adopted to preserve the facade of existing cultural assets with effect and alter the interior space freely. But many problems have been occurred over all the converted buildings with the passing of the years as a result of unfeasible design guidelines. Accordingly, the thesis is to propose the problem and assignment in a setting for a display through the conversion for exhibition of Korean traditional houses designated as modern cultural heritage focused on Riwhachang Choi Sunu House. The results are as follows; The exhibition circulation is continuously connected with each room, considering the previous life-style. The interior design elements are preserved according to the stand-up and sitting style. It is possible to put on one sided wall display in stand up style(Rhiwhachang), and island showcase display in sitting style(Choi Sunu House). And also these apparatus is suitable for the existing window pattern and frame. Therefore, this study is to suggest an assignment of design guideline for exhibition reuse in Korean Traditional Houses as well as the sustainable preservation of cultural assets as modern house.

최근 각종 회전전기의 설계제작에 있어서 그경제성과 신뢰성을 높이고저 가능한 한고속화 내지는 단일화 경향에 있다. 예로써 1,500MV급 주발전기라면 8MW라는 려자전력이 필요하므로 이를 종래의 직결직류려자기방식으로서는 정류조건에서 제한을 받게된다. 고로이러한 난문제의 해결책으로서 직류여자기의 감속, 별치의 M-G Set, 또는 이중전기자법등이 고찰되고 있으나 역시 과담한 경제문제를 수반하게 된다. 또한 각종산업의 발달에 따라 요구되는 부하특성과 가혹한 환경조건에서 운전되어야할 경우가 증가되고 있다. 즉 염소Gas, 아유산 Gas, 인화유기 또는 공해상등을 막론한 주위조건에서 방식방폭의 안정성과 소형경량화의 경제성등을 설계의 주요목적으로 본다. 이것은 회전전기의 고정자와 회전자간에 전달되는 전기적 Energy가 회전기계의 가장 약점인 탁동부분을 통과하기 때문이다. 여기에서 탁동부를 제거할 수단으로 Brushless 려자방식이 고안되었으며 오래전부터 그 Idea가 창안되어 있었으나 최근 갑자기 극소용량급에서 초대용량급에 이르기까지 Brushless화 되었음은 재료과학에서 본 자기증중기 또는 반도체공학의 발달이 크게 영향하였다. 필자는 여기에 발전기를 중심으로 Brushless 려자방식의 종류와 문제점을 검토하여 금후 발전될 전망에 대하여 간단히 논한다.
