Confucius asserted that the most humane life is to realize the value of 'benevolence(仁) as a human Virtue(德). Mencius also concurred that Confucius's explication of the good life was right. Confucian human mind & it's nature is comprised of benevolence, righteousness(義), propriety(禮) and wisdom(智). Confucianism proposed that we have to approach to other man as benevolence(仁). Mencius discussed about 'Four Virtues(四德)', the essential goodness of human, confirmed by 'Four Clues (四端)' to talk about the possibility of realizing the good life and a good state. On the other hand, he devised Politics of benevolence(仁政)' as a practical tool for it. Confucianism consider a human beings as human relationship. Confucius said, "benevolence(仁) is to love all men, and wisdom to know all men"In generally, Profit(利) is subject to righteousness in Confucianism. Therefore, Confucius said, "When you see Profit, think about Righteousness "But Confucius understands that Profit is ground for the constitution of 'Good life', and 'good State.'In Confucianism, Human Virtue is the root, Wealth is the result. In a State Gain is not to be considered propriety, its propriety will be found in righteousness.

Poly(lactic acid)(이하 PLA라 칭함)는 1970-80년대의 초기 연구에서는 높은 제조비용과 희귀성에 의해 봉합사와 약물전달시스템으로 용도가 제한적이었으나 1980년대를 거쳐 1990년 이후 농업의 혁신적인 변화를 거쳐 옥수수의 다양한 측면의 이용의 하나로서 6-7년 전부터 양산화에 성공하여, 의류, 필름 및 플라스틱의 여러 가지 분야에서 적용가능성을 모색하고 있다. PLA의 장점은 석유가 아닌 천연 원료에서 얻을 수 있으며, 기존의 합성섬유와는 달리 일정한 조건하에서 미생물 등에 의해 물과 이산화탄소로 90% 이상 분해되는 친환경적인 소재이다. 합성섬유에서 의류용으로 대부분 사용되는 폴리에스테르(이하 PET라 칭함)와 유사한 물성을 가지고 있는 PLA섬유는 PET섬유와 유사한 분산염료로 염색할 수 있다. 따라서 PLA섬유는 분산염료에 의한 염색법을 중심으로 연구되어지고 있으나, PET 섬유의 융점이 $254^{\circ}C$부근인 반면, PLA섬유는 $160-170^{\circ}C$부근이다. 이로 인해 PLA를 섬유로 용도전개에 있어서 약점으로 작용하고 있다. 그러나 PLA섬유는 특유의 경량감과 새로운 촉감 등의 많은 장점을 지니고 있어 여러 가지 용도전개가 되어지고 있다. 초음파는 사람이 들을 수 없는, 사람마다 한계값은 다르지만, 주파수 약 25kHz이상의 음파를 말하며, 주파수가 높고 파장이 짧기 때문에 강한 진동을 수반한다. 초음파의 이용 원리는 Cavitation이라는 현상으로 생성된 기포가 터지면서 강력한 에너지를 방출한다. 이것은 강력하여 사방으로 퍼져 물질표면이나 내부에 영향을 미친다. 섬유에서는 표면에 뭍은 불순물을 제거하는 세정 등에 응용되고 있으며, 염색분야에서도 다양하게 연구되어지고 있다. 본 연구에서는 초음파에 의한 PLA섬유의 염색성을 조사하였다. PLA섬유를 정련하여 초음파작용의 유무에 따라 염색하여 그 결과를 고찰하였다. 초음파 작용에 따른 분산염료의 표면 색변화는 없었으며, 섬유 표면 색 농도의 차이는 초음파 작용에 의하여 저온에서는 차이가 나타나지만, 고온인 $80^{\circ}C$에서는 오히려 낮아졌다.

This study was conducted to investigate the effect of methanol extract of Allomyrina dichotoma larva (MEAL) on carbon tetrachloride $(CCl_4)-induced$ hepatotoxicity in mice. ICR mice were divided into 5 groups [Vehicle control, $CCl_4\;(10{\mu}g/g)$ alone, $CCl_4$ plus a low dose $(50{\mu}g/g)$ of MEAL, $CCl_4$ plus a high dose $(100{\mu}g/g)$ of MEAL]. Silymarin $(2{\mu}g/g)$ was used as the reference in the experiment. Administration of MEAL tended to decrease the serum alanine transaminase (ALT) activity induced by $CCl_4$ treatment in mice. Hepatic concentration of thiobarbituric acid-reactive substances (TBARS) in a high-dose group of diet decreased to the level of silymarin-treated group. Hepatic activity of glutathione S-transferase in MEAL-treated group was lower than that of $CCl_4-treated$ group. Serum concentration of bilirubin was significantly increased by $CCl_4$ treatment, but MEAL or silymarin recovered the level. These results suggest that MEAL may exert the protective effect against $CCl_4-induced$ hepatotoxicity in mice. However, more intensive studies would be needed to elucidate the protective mechanism of the beetle on hepatotoxicity of mice.

The values of material civilizations that dominated the last century have been replaced with invisible values such as knowledge, information, and culture. The central axis of the world economy is also rapidly shifting from a capital and labor-intensive industry to a knowledge-based industry of software and contents. From the perspective of the industrialization of culture as multinational corporations and dominance and subordination relationships between cultures thereof, and crisis of cultural identity, the issues of support and fostering a culture industry arise. These have become major issues of concern in deciding national policies. In response to this trend, new departments related to culture contents in various universities have been established for fostering manpower in the field and the government policy to foster related human resources. However, actual results have not been currently achieved, despite the increase in quantity. This is due to the fact that the walls between culture contents departments were too high and thus education and fostering excellent human resources have not been properly conducted. It is also due to the obscure direction of education and a deficiency in the system. To cope with these problems, a systematic manpower-fostering education program should be developed through enhancement of the understanding of culture contents via linking education programs with detailed major fields of study. Accordingly, this study aims to identify changes in the current culture contents industry at home and abroad according to digitalization for fostering manpower of culture contents required in a rapidly changing environment of the culture contents industry. Then, it will review what influence has been made on the education system through the identification of personnel types through work flow charts and contents delivery modes following integration, as well as a desirable method to construct culture contents. Therefore, this study is a preliminary study on the means of fostering core personnel in the culture contents industry through linkage with the education system.

지금까지 국내에서의 수질개선을 위한 노력은 점오염원에 대한 저감만을 중심으로 진행되어 왔기 때문에, 보다 획기적인 수질개선을 위해서는 비점오염에 대한 연구와 관리가 진행되어야 한다. 그러므로 본 연구에서는 도시지역, 농촌지역, 임야지역의 토지이용특성이 다른 3유역을 대상으로 현장연구를 실시하여 비점오염물질의 발생특성 및 유역별 비교를 실시하였다. 측정은 도시지역의 가장 큰 오염원인 CSOs(Combined Sewer Overflows)에 대하여 측정을 실시하였고, 농촌지역 및 임야지역의 경우 각 유역의 출구 지점에서 측정을 실시하였다. 강우특성이 다른 15개의 강우사상을 대상으로 유량 및 SS, TCOD, TN, TP의 항목에 대하여 한 강우사상당 $15\~20$회의 측정을 실시하였다. 각각의 강우사상에 대하여 EMCs(Event Mean Concentrations)를 산출하여 도시지역, 농촌지역, 임야지역의 각 유역에 대한 확률별 EMCs를 산정한 결과 3개 유역의 EMCs는 도시지역>농촌지역>임야지역 순으로 나타났다. $EMC_{TCOD}$는 도시지역과 농촌임야지역간에 가장 큰 차이를 보이는 것으로 나타났으며, $EMC_{TN}$에서 가장 작은 차이가 나타났다. 각 유역별 EMCs의 로그-정규 확률그래프의 분산계수를 비교한 결과 농촌임야지역은 도시지역에 비하여 오염물질의 농도 변화가 강우특성에 따라 보다 큰 변화를 보이는 것으로 나타났다. 연구유역에서 $EMC_{TN}$의 발생확률 $50\% 값이 도시지역은 17.0mg/L, 농촌임야지역은 4.5mg/L로 나타났으며, 이는 유사한 유역특성을 나타내는 타 지역에서의 연구자료를 분석 값과 매우 유사한 크기를 가지는 것으로 나타났다.를 분석하였다. 실험을 수행하여 보다 정밀한 공식으로 개선할 수 있었다.$10,924m^3/s$ 및 $10,075m^3/s$로서 실험 I의 $2,757m^3/s$에 비해 통수능이 많이 개선되었음을 알 수 있다.함을 알 수 있다. 상수관로 설계 기준에서는 관로내 수압을 $1.5\~4.0kg/cm^2$으로 나타내고 있는데 $6kg/cm^2$보다 과수압을 나타내는 경우가 $100\%$로 밸브를 개방하였을 때보다 $60\%,\;80\%$ 개방하였을 때가 더 빈번히 발생하고 있으므로 대상지역의 밸브 개폐는 $100\%$ 개방하는 것이 선계기준에 적합한 것으로 나타났다. 밸브 개폐에 따른 수압 변화를 모의한 결과 밸브 개폐도를 적절히 유지하여 필요수량의 확보 및 누수방지대책에 활용할 수 있을 것으로 판단된다.8R(mm)(r^2=0.84)$로 지수적으로 증가하는 경향을 나타내었다. 유거수량은 토성별로 양토를 1.0으로 기준할 때 사양토가 0.86으로 가장 작았고, 식양토 1.09, 식토 1.15로 평가되어 침투수에 비해 토성별 차이가 크게 나타났다. 이는 토성이 세립질일 수록 유거수의 저항이 작기 때문으로 생각된다. 경사에 따라서는 경사도가 증가할수록 증가하였으며 $10\% 경사일 때를 기준으로 $Ro(mm)=Ro_{10}{\times}0.797{\times}e^{-0.021s(\%)}$로 나타났다.천성 승모판 폐쇄 부전등을 초래하는 심각한 선천성 심질환이다. 그러나 진단 즉시 직접 좌관상동맥-대동맥 이식술로 수술적 교정을 해줌으로써 좋은 성적을 기대할 수 있음을 보여주었다.특히 교사들이 중요하게 인식하는 해

The efficiency of a catalytic converter depends on the flow distribution across a system's chemically active substrate. If irregularities or non-uniform flow patterns exist, the system's conversion efficiency decreases, whereas the manufacturing cost increases. Therefore, it is important to analyze the internal flow of a catalytic converter. In this study, flow pattern measurements along the minor axis were recorded at the mid and exit planes of a ceramic honeycomb catalytic converter at flow rates of 37.8 l/s and 94.4 l/s. Flow distributions of the measurement plans were compared with an automotive company's computed velocity profiles. Measurements along the minor axis showed uneven velocity profiles. The ${\upsilon}$-velocity components between the honeycomb bricks were small but somewhat erratic opposite the intake side of the converter, however, they became flatter in measurements recorded near the intake entrance. For almost all velocity values, the computer model suggested velocities greater than the measured values.

The Accommodational missionary method adopted by the Jesuit missionaries who came to China in the late Ming and early Qing dynasty is called the Accommodation and Naturalization and is based on the Poetry. The terms they borrowed were 'Di(Emperor Above)' and 'Tian(The heaven)', the key terms of Confucianism. Although 'Di' was a new transcendent concept, its status was downgraded in the political upheaval, and 'Tian' was rather elevated. However, both of these concepts gradually transformed into philosophical concepts that directly affect real life. The two terms borrowed to express the priesthood could not contain the uniqueness of Christianity, and Christianity was interpreted as an extension line of Confucianism thinking, reduced to an adjunct of Confucianism, and was not indigenous to the depth of ideology. A rational philosophical inquiry could not have played a full role in guiding the Chinese into the true Christian 'faith' unless it is paired with the great teachings of revelation. It is necessary to analyze these results soberly to find problems and to try various studies to explore ways to open up new horizon for Christian missionary work.

Safety is one of the key issue in the regulation of cosmetics. Cosmetic Act deals with it in Korea. The guidance for the testing cosmetic ingredients and their safety evaluation are prepared by Korea Food and Drug Administration. Ultraviolet radiation could Induce skin damage, edema, erythema, photoaging, immune dysfunction and skin cancer. Ultraviolet radiation is classified as Group 2A(probably carcinogenic to humans) by International Agenry for Reaserch on Cancer(IARC). The in vitro methodologies for evaluating the toxic potential of ingredients reported in the literature have not yet been sufficiently validated for use in areas other than the study for mutagenicity/genotoxicity, for pre-screening for severe irritancy, for screening of phototoxicity and for evaluating the percutaneous absorption. The 3T3 neutral red uptake photoxicity test (3T3 NRU PT) was accepted as OECD toxicity guideline in 2002. The 3T3 NRU PT is an in vitro method based on a comparison of the cytotoxicitv of a chemical when tested in the presence and in the absence of exposure to a non-cytotoxic dose of UVA/visible light.

The GTL(Gas to Liquids) technology, manufacturing synthesized oil from natural gas, had been developed about 1920 for the military purpose by Fischer and Tropsch, German scientists. And 1960, Sasol company had started commercializing the FT(Fischer-Tropsch) synthesis technology, for the transport fuel in South Africa. Until a recent date, the commercialization of GTL technology had been delayed by low oil price. But concern about depletion of petroleum resources, and development in synthesizing technology lead to spotlight on the GTL businesses. Especially, Qatar, which has rich natural gas fields, aims at utilizing natural gas like conventional oil resources. Therefore, around this nation, GTL plants construction has been promoted. There are mainly 3 processes to make GTL products(Diesel, Naphtha, lube oil, etc) from natural gas. The first is synthesis gas generation unit reforming hydrogen and carbomonoxide from natural gas. The second is FT synthesis unit converting synthesized gas to polymeric chain-hydrocarbon. The third is product upgrading unit making oil products from the FT synthesized oil. There are quite a little sulfur, nitrogen, and aromatic compounds in GTL products. GTL product has environmental premium in discharging less harmful particles than refinery oil products from crude to the human body. In short, the GTL is a clean technology, easier transportation mean, and has higher stability comparing to LNG works.

As media and product became variety, the propensity of the people is be coming various. From diversity, there we could search for some popularity is called 'the mania.' When Mania takes shape, the product will being longer even masses in these days only have short-term life. Also there are hundreds of animations that has short-term life whom people forgot everyday they watch. However, the animations could lasting its value which has the Mania. This thesis is a studies on the constitution of Mania from animation 'Fullmetal Alchemist's Character The BONES had made. We can learn that the audience were not just like the animation, but get crazy for it by comparing Japanese animation industry in those days; before it has been shrinking and manufacturing various contents from Fullmetal Alchemist means there is enough consumtions. There are many reasons to form Mania group, but specially the character symbols at the works as a whole. From this study is to know a cause of how the animation 'Fullmetal Alchemist' made huge Mania group, and significance value of the work those group left.
