Purpose: Several studies have proven that EGCG, the primary green tea catechin, and glucosamine-6-phosphate (PGlc) reduce triglyceride contents in 3T3-L1 adipocytes. The objective of this study is to evaluate the combination effect of EGCG and PGlc on decline of accumulated fat in differentiated 3T3-L1 adipocytes. Methods: EGCG and PGlc were administered for 6 day for differentiation of 3T3-L1 adipocytes. Cell viability was measured using the CCK assay kit. In addition, TG accumulation in culture 3T3-L1 adipocytes was investigated by Oil Red O staining. We examined the expres-sion level of several genes and proteins associated with adipogenesis and lipolysis using real-time RT-PCR and Western blot analysis. A flow cytometer Calibar was used to assess the effect of EGCG and PGluco on cell-cycle progression of differentiating 3T3-L1 cells. Results: Intracelluar lipid accumulation was significantly decreased by combination treatment with EGCG $60{\mu}M$ and PGlc $200{\mu}g/m$ compared with control and EGCG treatment alone. In addition, use of combination treatment resulted in directly decreased expression of $PPAR{\gamma}$, $C/EBP{\alpha}$, and SREBP1. In addition, it inhibited adipocyte differentiation and adipogenesis through downstream regulation of adipogenic target genes such as FAS, ACSL1, and LPL, and the inhibitory action of EGCG and PGlc was found to inhibit the mitotic clonal expansion (MCE) process as evidenced by impaired cell cycle entry into S phase and the S to G2/M phase transition of confluent cells and levels of cell cycle regulating proteins such as cyclin A and CDK2. Conclusion: Combination treatment of EGCG and PGlc inhibited adipocyte differentiation through decreased expression of genes related to adipogenesis and adipogenic and cell cycle arrest in early stage of adipocyte differentiation.

The purpose of this study is to evaluate the effect of Dulegil in Bukhansan National Park in dispersing peak climbing hikers, characterize each section of Dulegil and suggest ideas of improvement. This study was conducted based on the survey completed by visitors in all 21 sections of Dulegil. After the construction of Dulegil, the number of visit to Dulegil grew and it was analyzed that Dulegil attracted new visitors given that the rate of young people(aged 19~30) who visited for the first time was quite high. Regarding the frequency of peak climbing, 7.6% of the respondents said "decreased" and 46.2% said "increased", showing that Dulegil's effect to disperse peak climbing hikers is nominal. Seven qualities were evaluated regarding Dulegil's level of satisfaction. Out of those seven, the quality of recreational place and taking a walk achieved high scores of 3.74 and 3.61 respectively. The quality of culture and history scored the lowest with 3.09. The analysis on the characteristic of each section of Dulegil, reason of visit, and the visitors' level of satisfaction showed that Dulegil is now regarded as a place where they can improve their health through light exercise and walking. In addition, a positive effect can be expected for a long time since there are different ways of utilizing the resources of the National Park, such as getting in touch with nature, preserving ecology, learning history and enjoying beautiful landscapes. If infrastructure and programs specific to each section of Dulegil were improved in a long-term perspective, it would be effective to encourage peak climbers and enjoy the lower parts of the mountain.

Natural products has been occasionally used in place of growth regulators to control lateral root formation and growth of soybean sprouts. The study was done to measure the effects of treatment concentration of hard rubber tree (Eucommia ulmoides Oliver) leaf extract on lateral root formation, growth and morphological characters of the sprouts. Seeds of three cultivars, Pungsannamulkong, Sowonkong and Junjery, were imbibed for 5 hours into water, its 5 and 10% solutions immediately before 6 day culture. The cultured sprouts were classified into 4 categories to calculate their composition rates on the base of hypocotyl lengths; >7 cm (A),4 to 7 cm (B),<4 cm (C) and not germinated (D), and their morphological characters, fresh and dry weights were measured. Rate of A was decreased with increased concentrations, while that of C showed reverse result compared to A. Regardless of concentrations, the former rate was less in cv. Junjery than in cv. Pungsannamulkong and Sowonkong than in cv. Junjery although the latter rate was truly opposite to the former one. In 10% treatment concentration, lateral roots were less formed in cv. Junjery although nearly formed in cv. Pungsannamulkong and Sowonkong. In all the 3 cultivars, lateral roots per sprouts were decreased with increased treatment concentration. shorter and thicker sprout was observed in cv. Junjery than in the other cultivars, and in increased concentrations compared to relatively lower ones. Total fresh weight was the greatest in cv. Sowonkong due to mainly increment of its hypocotyl, but was reduced with increased concentration due to mainly decrement of hypocotyl in all the cultivars.

This study examines the universal meaning of the roof-end tile, our cultural property, and especially focuses on an ontological interpretation of the "Smile of Silla" roof-end tile. In addition, the problem of good and evil read here is considered in connection with the universal problem of philosophy. The issue of good and evil is a theme in philosophy, theology, religion, and culture that will endure throughout human history in both the East and the West. Augustine and Schelling inquired deeply into the source of evil and obtained an answer to this question based on their methods, but their answer is not universal or absolute, or an answer that applies to everyone. This is because the issue of good and evil possesses both a direct relationship with every human being and a characteristic that will remain unresolved. That is to say, the metaphysical question regarding the source of evil will always be one that is open. Nietzsche, however, repudiated the morals handed down through Socrates and Christianity, and urged that we reside "beyond good and evil." This brief review argues that good and evil exists in the form of a being in itself, whether it is within our grasp or not, and reveals that good and evil is more "this-worldly" than it is "other-worldly". The roof-end tiles with facial markings passed on to us also presuppose that evil is in full force in this world and exerts its influence. This review taps into several folk methods for coping with the existence of an invincible evil that surpasses human capability and contemplates the extraordinary and creative ideas of the Silla people through their "Smile of Silla" roof-end tiles with facial markings that were used to counter evil.

Hyang-Yack-Ku-Keup-Bang(鄕藥救急方) is our own, medical work written about the middle of the time of Korea Dynasty. I restored and researched this book because it needed to be illuminated about its medico-historic value and then I came to some conclusions as follows. 1. Hyang-Yack-Ku-Keup-Bang was published in Dae-jang-do-kam(大藏都監) of Kanghaw island(江華島) about the middle of Korea Dynasty. Choi Ja-ha(崔自河) republished it on original publication ground in Euiheung(義興) of Kyungsang-Province(慶尙道) in July, Taejong's(太宗) 17th year of Chosen Dynasty (A.D.1417) and this book was published again in Chungcheng Province(忠淸道) in Sejong's(世宗) 9th year(A.D.1427). The book published in Taejong's days was in the possession of books department of Kung-nae-cheng(宮內廳) in Japan and was the oldest medical book of existing ones. 2. Bang-Jung-Hyang-Yack-Mock-Cho-Bu(方中鄕藥目草部) of this book was originally intended to be adjusted in each division with the title of Bang-Jung-Hyang-Yack-Mock(方中鄕藥目). But Herb part(草部) only followed editing progress of Jeung-Lew-Bon-Cho(證類本草), the rest is not divided into each part and is together arranged at the below of Herb part with the title of Bang-Jung-Hyang-Yack-Mock-Cho-Bu. The Korean inscriptions on some drugstuffs in this book are different between Native Name(鄕名) of three volumes of provisions and general-spoken(俗云) of Bang-Jung-Hyang-Yack-Mock-Cho-Bu. In this, it is estimated that the publishing time and editor of tile volume of provisions and Bang-Jung-Hyang-Yack-Mock-Cho-Bu are different. I think Choi Ja-ha compiled this behind three volumes of provisions when he published. 3. This book picked some prescriptions which consisted of obtainable drugs with ease in Korea in the books of Chell-Keum-Yo-Bang(千金要方), Oi-Dae-Bi-Yo(外臺秘要), Tae-Peong-Sung-Hye-Bang(太平聖惠方), Ju-Hu-Bang(?後方), Kyung-Hum-Yang- Bang(經驗良方) Bo-Je-Bon-Sa-Bang(普濟本事方) Bi-Ye-Baik-Yo-Bang(備預百要方) and so on and got together our own prescriptions. On the whole Bi-Ye-Baik-Yo-Bang was a chief referrence book, On this, other books referred to and corrected. 4. In provisions quoted from Hyang-Yack-Jip-Sung-Bang(鄕藥集成方), there are seven provisions; leg-paralysis part, coughing part, headache part, obstetrics part, etc. don't show in this book. This is why Choi Ja-ha published only certain texts on Dae-jang-do-kam edition his own posession. So we can think the existing edition has a little misses compared with original edition. 5. This book recorded only names of drugstuffs in animal drug department like fowls, crab, goldbug, earthworm, etc. and didn't tell us ways of taking those. This is effect of Buddhist culture on medicine. This is efforts to practice 'Don't murder';one of Five Prohibition of Buddhism. 6. Beacause this book was published at the time, when our originative medicine would be set forth. This followed the Chinese ways in Theory, Treatment, Prescription and used 'Hyang Yack' in Medication out of theory of Korean medicine, which was a transitional form. So this is all important material which tell us aspects of development of 'Hyang Yack' the middle of Korea Dynasty.and this is also the beginning of originative, medical works like Dong-Eui-Bo-Kam(東醫寶鑑), Dong-Eui-Su-Bo-Won(東醫壽世保元). 7. There are few contents based on 'Byen-Jeung-Lon-Chi(辨證論治)'in this book. So we can see this book is not for doctors who study medical thoughts but for general public who suffer from diseases resulted from war. Because this book was written for a first-aid treatmeant, this is an index of medical service for the people those days. And this is also an useful datum for first-aid medicine or military medicine in these modern days. 8. Nowadays, parts of learned world of Korean medicine disregard essential theories and want to explain Korean medicine only by the theories or the methods of Western medicine. Moreover they don't adopt Chinese and Japanese theorys & thoughts about Oriental medicine in our own style and just view in there level. What was worse, there is a growing tendency for them to indulge in a trimming policy of scholarship and to take others' ideas. I think these trends to ignore our own medical thoughts involving growth of 'Hyang Yack' in the middle of Korea Dynasty, Dong-Eui-Bo-Kam and Dong-Eui-Su-Se-Bo-Won. So we, as researchers of Korean medicine, must get out of this tendency, and take over brilliant tradition and try to develop originative Korean medicine.

The protective effects of ethanol extracts from 5 seaweeds on the mutagenic and cytotoxic damage were evaluated. They were separately extracted using ethanol from dried samples at room temperature, and freeze-dried. The inhibition effects on the mutagenicity in Salmonella assay by Ames test and cancer cell inhibitory effect in HeLa cell, MCF-7 cell and SNU -638 cell by MTT assay were assayed. Seaweed fusiforme, sea tangle and green laver showed strong inhibitory effect against 2-nitrofluorene, sodium azide- or 2-anthramine-induced mutagenicities in Salmonella Typhimurium TA 98 and TA 100 at the level of 2.5 mg ethanol extract per plate. Cancer cell inhibitory effect was shown with all of the seaweed extracts. Green laver, sea mustard, sea tangle and seaweed fusiforme showed strong cytotoxicity against HeLa and MCF-7 cells, with inhibiting by $92\~93\%$ and $89\~92\%$, respectively. These data show that 5 seaweeds tested in this study might be potent functional foods for cancer prevention, and consumption of these seaweeds in adequate amount is recommended.

It is generally regarded a design system in post-industrial society, which products designed by in-house designers or design consultancy are manufactured in factory and distributed in market for the consumer. Although it is treated an old design system in traditional society, the traces of vernacular design has been remaining in the state of adopted to the periodical needs in these days, also proving the attribute of design culture to constitute human's material environment as well as existing design systems. There were discovered various design artifacts in daily surroundings vary from the established design in several manners, user modifications or manufactures in everyday lives formalized them. It was approached a case study that analyze the changes of artifact configuration and designer/user context and creation process of the non-professional design artifacts, Creativity Template Theory and ACM(Artifact Context Model) have been utilized for the analysis model. From the analysis result, It assume that the everyday artifacts may be ordinary but extra-ordinary including particular ideas and identity represented by everyday designers or users. Beside these characteristics induce the potentiality that reflect on creative motives for the designers or a complementary artifact generator filling up with drawbacks in established design system. The everyday design domain, various explorations and alternatives are made, is seems to be another design practice domain dissimilar to the one in the industry-based design. Moreover it provides an more easily accessability for the approaching user-friendly design, user customization because they conduct the reliable modeling of consumer and end-user. Finally, based on the exploratory study regarding interpretation of context and configuration in the everyday artifacts, new approach for the design process and design education through more detailed cognitive modeling of everyday designers will be a further study.

Augmented Reality, virtual reality in recently attracted attention throughout the world. and Mix them mixed reality etc., it has had a significant impact on the overall pop culture beyond the scope of science and technology. The world's leading IT company : Google, Apple, Samsung, Microsoft, Sony, LG is focusing on development of AR, VR technology for the public. The many large and small companies developed VR hardware, VR software, VR content. It does not look that makes a human a human operation in the cognitive experience of certain places or situations or invisible through Specific platforms or program is Encompass a common technique that a realization of the virtual space. In particular, out of the three-dimensional image reveals the limitations of the conventional two-dimensional structure - 180, 360 degree images provided by the subjective and objective symptoms such as vision and sense of time and got participants to select it. VR technology that can significantly induce the commitment and participation is Industry as well as to the general public which leads to the attention of colostrum. It was introduced more than 10 related VR works Year 2015 Sundance Film Festival New Frontier program. The appearance VR content : medical, architecture, shopping, movies, animations. Also, 360 individuals can be produced by the camera / video sharing VR is becoming an interactive tunnel between two possible users. Nevertheless, This confusion of values, moral degeneration and the realization of a virtual space that has been pointed out that the inherent. 4K or HUD, location tracking, motion sensors, processing power, and superior 3D graphics, touch, smell, 4D technology, 3D audio technology - It developed more than ever and possible approaches to reality. Thereafter, This is because the moral degeneration, identity, generational conflict, and escapism concerns. Animation is also seeking costs in this category Reality. Despite the similarities rather it has that image, and may be the reason that the animation is pushed back to the VR content creation. However, it is focused on the game and VR technology and the platform that is entertaining, but also seek new points within the animation staying in the flat Given that eventually consist of visual images is clear that VR sought. Finally, What is the reality created in the virtual space using VR technology could be applied to the animation? So it can be seen that the common interest is research on what methods and means applied.
