This study analyzes the characteristics of the social value creation process through the collective appreciation of film. It focuses on the historical development of community cinema in Japan. In modern-day Japan, where digital video is easily accessible and the use of private, personalized media spaces widespread, a sub-culture of collective film appreciation is spreading, as more and more Japanese begin to attend movie screenings in non-commercial theaters. In addition, Japanese community cinema center has begun to integrate and support this viewing experience, which has come to be known as community cinema. A literature review revealed the following characteristics of community cinema. First, local theater screening groups or appreciation groups cooperate with residents to establish and operate movie theaters. Second, these spaces create theoretical and practical participatory learning opportunities that foster understanding of and participation in film culture, through large-scale associations with organizations or institutions that offer viewings. Third, based on collective appreciation, the film culture created through repeated joint viewings produces a social arena in which community can be realized. In these communities film can be put to socially productive uses, such as problem solving.

The purpose of this study was to analyze the commemoration culture of Vietnam War Memorials (VWM) in Vietnam. Through site survey, the researcher selected 23 VWM in Vietnam and analyzed 5 categories: memorial type, design concept and narratives, location and spatial form, landscape elements, and content expressed in landscape details. The results are as follows: 1. Because of the long, drawn out Vietnam War, which lasted from 1955 to 1975, VWM were divided into 10 types mainly as soldier cemeteries based on a traditional memorial style, battlefields and places of tragedies considering sense of place, war museums representing victory and atrocity in war, and peace parks promoting reconciliation and peacemaking. 2. The analysis revealed that the main concepts and narratives of VWM were to value the victims of the Vietnam War, remember soldiers' contributions, highlight the victory in war and resistance to the United States, and express a sense of place. Peacemaking applied only to My Lai Peace Park and Han-Viet Hoa Binh Cong Vien, built by international cooperation. 3. Cemeteries and appreciation memorials were designed to follow a traditional memorial space form that highly regard both axis and symmetry. The design concept at battlefields and places where tragedies occurred depended mainly upon a sense of place and used symbolic landscape elements to compensate for the undefined concept. 4. Sculptures and towers were mainly used to highlight war victory and resistance as the representative style of a Socialist country, weapons and pictures exhibited in war museums and battlefield showed the reality and strain of war. Symbolic elements of Buddhism and Confucianism were often introduced as a way to venerate the memory of deceased persons. 5. The state and heroic actions in the Vietnam War were realistically depicted on sculptures and walls. Also, the symbolic phrase, 'TO-QUOC-GUI-CONG' meaning 'our country remember your achievement', were written on the memorial tower and 'Quagmiire' was used to metaphorically represent the difficulties faced by the U.S. military on battlefields during the war and the uncertainly that pervaded U.S. society in those days. 6. In VWM, ideologies like nationalism, patriotism, socialism, capitalism were mixed and traditional cultures like Buddhism, Confucianism, Taoism were inherent. Differing from their Confucianism culture, war heroes, particularly including women, were often described by sculpture, monument, and pictures and the conflict in and outside the country regarding the Vietnam War was shown. Further study will be required to analyze design characteristics of VWM in the u.s. and to understand the difference in commemoration cultures between Vietnam and the U.S.

ZnO박막은 넓은 밴드갭 (3.37 eV), 높은 여기 결합 에너지 (60 meV)를 가지는 육방정계 우르자이트(hexagonal wurtzite) 결정구조를 가지는 II-VI족 화합물 반도체로, 가시광선 영역에서의 높은 광학적 투과도 특성과 자외선 파장에서 발광이 가능한 장점을 가진다. 최근, ZnO박막 성장 기술이 상당히 발전하였지만, 아직까지도 p-형 ZnO박막 성장 기술은 충분히 발전하지 못하여 ZnO의 동종접합 LED는 아직 상용화되지 않고 있는 실정이다. 따라서, 많은 연구 그룹에서 p-GaN, p-SiC, p-diamond, p-Si 등과 같은 p-type 물질 위에 n-type ZnO를 성장시킨 이종접합 다이오드가 연구되고 있다. 특히, p-GaN의 경우 ZnO와의 격자 불일치 정도가 1.8 % 정도로 작다는 장점이 있어 많은 연구가 이루어 지고 있다. 일반적으로 c-축을 기반으로 한 극성ZnO 발광다이오드에서는 자발 분극과 압전 분극 현상에 의해 밴드 휨 현상이 발생하고, 이로 인해 전자와 정공의 공간적 분리가 발생하게 되어 발광 재결합 효율이 제한되고 있다는 문제가 발생한다. 따라서, 본 연구에서는 극성 (0001) 및 비극성 (10-10) n-ZnO/p-GaN 발광다이오드의 성장 및 발광 소자의 전기 및 광학적 특성에 대한 비교 연구를 진행하였다. 금속유기 화학증착법을 이용하여 c-면과 m-면 위에 각각 극성 (0001) 및 반극성 (11-22) GaN박막을 $2.0{\mu}m$ 성장시킨 후 Mg 도핑을 한 p-GaN을 $0.4{\mu}m$ 성장시켜 각각 극성 (0001) 및 반극성 (11-22) p-GaN템플릿을 준비하였다. 이후, N2분위기 $700^{\circ}C$에서 3분동안 열처리를 통하여 Mg 도펀트를 활성화시킨 후 원자층 증착법을 이용하여 동시에 극성 및 반극성 p-GaN의 위에 n-ZnO를 $0.11{\mu}m$ 성장시켜 이종접합구조의 발광소자를 형성하였다. 이때, 극성 (0001) p-GaN 위에는 극성의 n-ZnO 박막이 성장되는 반면, 반극성 (11-22) p-GaN 위에는 비극성 (10-10) n-ZnO 박막이 성장됨을 HR-XRD로 확인하였다. 극성 (0001) n-ZnO/p-GaN이종접합 발광다이오드의 전계 발광 스펙트럼에서는 430 nm 와 550 nm의 두 피크가 동시에 관찰되었다. 430 nm 대역의 파장은 p-GaN의 깊은 준위에서 발광하는 것으로 판단되며, 550 nm 피크 영역은 ZnO의 깊은 준위에서 발광되는 것으로 판단된다. 특히, 10 mA 이하의 저전류 주입시 550 nm의 피크는 430 nm 영역보다 더 큰 발광세기를 나타내고 있다. 하지만, 10 mA 이상의 전류주입 하에서는 550 nm의 영역보다 430 nm의 발광세기가 더욱 증가하는 것을 확인할 수 있었다. 이것은 ZnO의 밴드갭이 3.37 eV로 GaN의 밴드갭인 3.4 eV다 작기 때문에 우선적으로 ZnO의 깊은 준위에서 발광하는 550 nm가 더욱 우세하지만, 지속적으로 전류주입 증가에 따른 캐리어 증가시 n-ZnO에서 p-GaN로 전자가 넘어가며 p-GaN의 깊은 준위인 430 nm에서의 피크가 우세해지는 것으로 판단된다. 반면에, 비극성 (10-10) n-ZnO/반극성 (11-22) p-GaN 구조의 이종접합 발광다이오드로 전계 발광 스펙트럼에서는 극성 (0001) n-ZnO/p-GaN에 비하여 매우 낮은 전계 발광 세기를 나타내고 있다. 이는, 극성 n-ZnO/p-GaN에 비하여 비극성 n-ZnO/반극성 p-GaN의 결정성이 상대적으로 낮기 때문으로 판단된다. 또한, 20 mA 영역에서도 510 nm의 깊은 준위와 430 nm의 발광이 관찰되었다. 동일한 20 mA하에서 두 피크의 발광세기를 비교하면 430 nm의 영역은 극성 n-ZnO/p-GaN에 비하여 매우 낮은 값을 나타내고 있다. 이는 반극성 (11-22) p-GaN의 경우 극성 (0001) p-GaN에 비하여 우수한 p-형 특성에 기인한 것으로 판단된다.

Fillets of mackerel (Scomber japonicus) and flounder (Xystrias grigorjewi) which, are representatives in red fleshed fish and white fleshed fish, respectively, were freeze-dried and stored in tightly sealed containers which were controlled to different relative humidity at $25^{\circ}C$. The changes of lipids were examined periodically by measuring the peroxide value (POV), the thiobarbituric acid (TBA) and the acid value (AV). And the fatty acid composition of lipids was investigated by gas-liquid chromatography (GLC). The results obtained are summarized as foollows: From the changes of POV and TBA value during storage, the oxidation of lipids was distinct at the lower relative humidities, $0\%\;and\;23\%$, while inhibited at the higher relative humidities, $52\%\;and\;81\%$. The changes in acid value during storage were more prominent at the hifger relative himidites than at the lower relative humidities. The content of $C_{16:0},\;C_{18:0}\;and\;C_{22:6}$ acids in the fatty acid composition of total lipids was abundant in both fleshed fishes. The content of $C_{18:1}$ acid in the nonpolar lipid and that of $C_{16:0}$ acid in the polar lipid were higher than other fatty acids. In the fatty acid composition of total lipids during storage, polyenoic acids decreased with storage period at $0\%\;and\;23\%$ relative humidities, while the fatty acid composition didn't show a great change at $52\%\;and\;81\%$ relative humidities. In the non-polar lipid, polyenoic acids coherently decreased under all the conditions of relative humidities but the saturated acids and the monoenoic acids increased. In the polar lipid, polyenoic acids decreased at $0\%\;and\;23\%$ relative humidities, while the saturated acids and monoenoic acids decreased at $52\%\;and\;81\%$ relative humidities. On the other hand, the oxidation of lipids was more significant in mackerel than in the flounder, and the changes of fatty acid composition were shown a similar pattern.

Among 20th century Western ideologies (Western civilization), existentialism is a spirit of the times to restore humanity as rationality and advanced technology have driven mankind to impoverishment and death, experiencing the First and Second World War, Great Depression, Fascism and the Spanish Civil War. In his literature, $Andr{\acute{e}}$ Malraux records his existential agony of how mankind lives and faces death by questioning the fateful life and death of characters. For Malraux's characters, the absurdity of existence related to the human identity means self-examination. Malraux explores existential consciousness and actions of characters in the presence of a concept known as death relative to terror, revolution, and adventure. Malraux deftly addresses the concept of death in his literary works, and it has being emphasized as a central subject for philosophical speculation. In Les $Conqu{\acute{e}}rants$(1928), La Voie Royale(1930), La Condition Humaine (1933), L'Espoir(1937), Malraux suggested a philosophical thesis of the meaning of life through characters in tragic situations, and sought out the consciousness of being and the existential meaning through how the characters control their fate. Malraux, in such a tragic perspective of the world, portrays humanity, affirmation of life, and characters' consciousness and actions in denying death. The agony of death triggers escapist behavior such as having unpredictable instinctual desires such as gambling or smoking opium, but these are desperate struggles to flee from frustration and related to the question of one's existence. What is always emphasized with respect to Malraux's existentialism is the tragic metaphysics of the inevitable destiny of the human condition eventually leading to the question of how humans ultimately confront death. But as characters unite in times of war, revolution and adventure in the novel, such cooperative actions symbolizes a keen sense of solidarity reflecting a camaraderie that transcends individualism. Fellowship among people who voluntarily gather for the common cause of philanthropy and restoring humanity is possible because of the underlying human greatness to sacrifice for such a noble cause. Therefore, Malraux's camaraderie includes the victory of existentialism in creating a world of humanism.

The main concern of the study is the playwrights' perspectives toward the relationship between society and individuals rather than specific cultural or social circumstances. This study is justified in that the similarities of both playwrights not only provide an opportunity to bridge two different cultures, but they also help readers understand another culture and deepen the understanding of their own culture in the map of international literature. In their plays, both Miller and Cha express an individual's or a family's frustration, conflict, pleasure, and hope as reflected in the social circumstances. The characters take ideas and values from their social world and thrive or fail. Specifically, I have focused on three elements--obsession, generational value systems, and alienation. With three common features, I examine how closely Miller and Cha deal with ordinary people's tragedies.

Flavours in kimchee are the result of unique combination of various sugars, organic acids and amino acids as well as various volatile organic compounds including sulfur-containing compounds, terpenes, alcohols, and some volatile organic acids. In the experiment for the flavour extracting methods, dynamic headspace(DHS) is more effective for collection of volatile flavour than simultaneous distillation extraction(SDE). The best polarity available at the moment is 5% phenyl methyl poly-siloxane which will separate non-polar, intermediate and polar components with good resolution.

Lion's Mane Mushroom, Hericium erinaceum, is a traditional edible mushroom widely used in culinary applications. It has been also used as a medicine in East Asian countries due to its various biological activities. Chemical investigation of fruiting bodies of this mushroom afforded many aromatic compounds, which were mostly isolated from polar fraction of its extracts. Herein we tried to investigate non-polar compounds from the extracts of this mushroom. $CHCl_3$-soluble fraction of the extracts was subjected to chemical investigation, which resulted in isolation of four compounds. Their chemical structures were elucidated as ircicerebroside (1), cortenuamide A (2), 1-D-arabinitol-monolinoleate (3), and cinnamic acid (4) on the basis of spectroscopic data. To the best of our knowledge, this is the first report of compounds 1, 2, and 4 from Hericium erinaceum.
