Suk‐Joon Yang,Young‐Eun Huh,Sung‐Hoon Park 한국국제경영관리학회 2005 국제경영리뷰 Vol.9 No.2

COO(원산지 효과)에 대한 많은 기존의 연구들이 이루어졌음에도 불구하고, 대부분의 기존의 연구들은 주로 전자제품 등의 공산품을 중심으로 또한 선진국-고품질 제품, 개발도상국 - 저품질 제품의 틀 속에서 연구가 주로 이루어져 왔다. 또한, COO를 통한 전반적인 마케팅 전략의 수립보다는 마케팅 프로세스의 일부분에 COO가 미치는 영향을 연구한 단편적인 연구가 대부분이었다. 이에 본 연구에서는 기존 연구와는 달리 선진국인 미국과 일본 시장을 대상으로 한국의 고품질 농산품인 “고려인삼”의 마케팅 전략의 수립이라는 전체적 측면에서 COO에 대한 기존 이론들을 검토하고 이를 실증하였다. 연구의 결과 고려인삼은 미국과 일본시장 모두에서 원산지 효과가 있는 것으로 나타났다. 하지만, 시장 세분화를 위한 가설인 고연령 - 저학력의 사람들에게 원산지 효과가 보다 유용하다는 가설은 기각되었다. 이는 과거의 연구와는 달리 개발도상국-고품질 제품의 조합이라는 제품 특성 때문인 것으로 보인다. 또한, 마케팅 전술을 세우기 위한 특정 유통 경로가 원산지 효과에 영향을 미친다는 가설은 미국과 일본시장에서 모두 지지되었으며, 제품에 대한 정보 원천이 원산지 효과에 영향을 미친다는 가설은 미국에서만 지지되고 있음을 확인하였다. 또한, 이러한 결과를 바탕으로 토의 부분에서 한국의 고품질 농산품인 고려인삼의 효과적인 미국과 일본시장에서의 마케팅 전략을 제시하고 있다. Most of the previous studies concerning American or Japanese market have focused on the difference in COO effects between indigenous product mostly with positive COO effect and foreign products mostly with negative COO effect. and, the previous COO research has concerned with the electric home appliances like TV or automobiles while there has hardly been research concerning the COO effect and its application strategies on agricultural products. But, our exploratory research on the agricultural product extends the product categories regarding COO effects and our study is concerned with foreign product which has positive COO effects in American and Japanese market. We can observe that there exists the COO effect on ginseng in American and Japanese market. but we can find some results which are not consistent with the previous research - especially, in demographic factors of america and information source of Japan. We explain the reason of this results and suggest new strategy of COO. Also, we suggest the marketing process to make use of the COO effects, which can be applied various product categories.

College of Engineering, Dankook University, Cheonan 330-714 and Bioproducts Research Center of Yonsei University, Seoul 120-749, Korea - From the soil collected form provincial area of South Korea, a microorganisms which have been shown good growth in the minimal poultry feces extract medium was isolated. Supplement of glucose to the poultry feces extract medium helped the complete degraded during the microbial growth. Maximum cell growth (3.8×10^9 CFU/ml) obtained at 36 hours of incubation after inoculation. Uric acid was degraded faster in minimal medium that in the glucose complement medium. VFA (volatile fatty acid), which are known as major compounds of poultry feces odor, were almost removed from the minimal poultry feces extract medium. Glucose supplement to the minimal medium enhanced the growth of microbial cells. Addition of 4% of glucose and 4% of neopeptone to the minimal poultry feces extract medium helped the maximal growth of cells.

컴퓨터 법에 있어서의 책임에 관한 연구

This paper, coauthored by Chin-Se Chung, as well as other 5 faculty members at Hong-Ik University Department of Law (Jea-Hwang Jeong, Suk-Ho Bang, Tae-Hoon Ha, Seong-Deog Yi and Bong-Chul Choi), deals with liability issuses surrounding constitutional law, administrative law, civil law (contracts, torts), commercial law, criminal law, international law and philosophy & law. Professor of Law Jea-Hwang Jeong makes a comparative analysis of privacy protection and disclosure of information legal issues, appeared at current Korean law and draft of law in case of the latter one. He suggestes some desirable ways of legislation through revision process and operation of legal rules at his paper. Professor of Law Suk-Ho Bang makes a brief survey of civil liability issues arising out of contracts and torts in English and American law, first. He tries to show that many Parts of arguments in such legal world are attributed to Statute of Frauds tradition, unique to such legal world. New developments in the area of torts, including computer malpractice and computer virus, are shown and analysed in terms of application possibility under our current law. But, as even the Anglo-American courts are found very reluctant to accept those arguments as new grounds for torts liability, it seems more plausible and practicable to refer to contractual approach, basically, rather than to torts approach even under English American law. Professor of Law Chin-Se Chung suggests in his paper on EFT that the allocation of liability under EFT be made under the new and most relevant principle, working for useful transmission way of fund, not solely under traditional legal principles. If such new principle works with high return of risk to users, it makes imminent problems against the goats of consumer protection, and eventually will be hardly refered to. Conversely, if it requires too much sacrifice from the side of banks, then the convenience in such system will not be utilized. So, it may be natural that EFT be discarded even without proper functioning under market system. In conclusion, Professor Chung points out that, only when banks fond that the economy out of cost-saving at tasks outweighs the risk undertaken by the banks, the banks will operate the system. But, if this system makes more return of benefits to the banks with the burden of users, it is against the idea of equity. Consequently, the banks should bear the aggeviated risks in return for the cost saved under this system Professor of Law Tae-Hoon Ha focuses his research paper on criminal liability under EFT. He draws his conclusion out of current criminal statutes that illegal fund transfer under automatic teller machines, cash cards and information system can not be penalized due to lack of proper statutory provision. So, the criminal provision on computer crime, newly made on December of 1995, can be positively appreciated. But, he anticipates that the question whether such new provision will be successful in regulating all illegal activites at fund transfor system without any operation defects in criminal code, or will cause new problem in interpretation of criminal code remains unsolved. Professor of Law Seong-Deog Yi examines the international legal issues which may be given rise to by direct satellite broadcasting. In his paper, the issue of national jurisdiction in relation to direct satellite broadcasting is firstly dealt with. Secondly, the possible ways in which direct satellite broadcasting is regulated by international law are examined with special emphasis of two different approaches, that is, freedom of information approach and state sovereignty approach. In this context, many international conventions concerning direct satellite broadcasting in Particular, and international regulatory regime of outer space in general are broadly reviewed. Thirdly, the types of activities which may be a violation of international legal regime of direct satellite broadcasting are suggested and the possible lethal remedies for these violations are proposed with the traditional international state responsibility law in mind. Professor of Law Bong-Chul Choi explores the relations of computerized society to its laws throughout his paper as a kind of conclusion of this whole paper. Computerized society is one that the technical, scientific, informational knowledge prevails. With correspondence to the structural change in knowledge, the law of such a society has suffered transformation, and the knowledge and techniques distributing and computing legal responsibility has also changed. However, he does not insist that the diffusion of technical knowledge is the sole factor of the transformation of legal responsibility. It is only one of the various factors. Moreover, he does not deny the continuation between the classical techniques distributing legal responsibility and the contemporary ones. In this era, the law realizes fairness and community values at the expense of singularities. In addition, he proposes that legal scholars take the diagnosis of law from the perspective of the technology/knowledge shifts seriously.

Hur, Sung‐,Taek,Lee, Bo Ram,Gim, Min‐,Jun,Park, Kyung‐,Won,Song, Myoung Hoon,Choi, Suk‐,Won WILEY‐VCH Verlag 2013 ADVANCED MATERIALS Vol.25 No.21

<P>A liquid‐crystalline blue‐phase laser with a tunable photonic bandgap (PBG) of over 150 nm and a wide temperature range is demonstrated by Myoung Hoon Song and Suk‐Won Choi on p. 3002. A lasing peak shift of more than 100 nm is realized due to the large PBG shift of the liquid‐crystalline blue phase. The shift in the lasing wavelength was reversible during repeated temperature changes over the entire stability range of the liquid‐crystalline cubic blue phase. </P>

윤석영,홍민표,김은호,공광훈 중앙대학교 기초과학연구소 2000 基礎科學硏究所 論文集 Vol.14 No.-

Alcohol dehydrogenase from Thermomicrobium roseum was purified to electrophoretic homogeneity approximately 77-fold with a 38% activity yield by adenosine 5'-monophosphate and Mono Q column chromatography. The molecular weight of the enzyme was determined to be approximately 43,000 by SDS-polyacrylamide gel electrophoresis and 88,000 by gel chromatography, indicating a homodimeric structure. The Km and Vmax values of the enzyme for ethanol were 24.2 mM and 12.8 ㎛ol/min/mg, respectively. Pyrazole notably inhibited the enzymatic activity. Ca2+ ion activated the enzyme activity, but Cu2+ inhibited. The activity of the enzyme was optimal at pH 10.0 and 60℃.

(Li_(0.5)Ln_(x)La_(0.5-x))TiO₃(Ln=Nd, Sm, Gd, Ho)계에서의 리튬 이온 전도 특성에 미치는 결정구조적 인자에 관한 연구

정훈택,명승택,연석주 東新大學校 工業技術硏究所 1997 工業技術硏究 Vol.3 No.-

We investigted lithium ionic conductivity in the (Li_(0.5)Ln_(x)La_(0.5-x))TiO₃ system (Ln=Nd, Sm, Gd, Ho), and found that the ionic conductivity increased with the increase of the atomic number in lanthanide system from Nd to Ho. We conducted our experiment in x=0.05 region in which no second phase and lattice parameter change were observed. Therefore, we concluded that the change of conductivity by A-site substitution is not due to the change of lattice parameter but other factors.

Low-viscosity composite resins may produce better sealed margins than stiffer compositions (KempScholte and Davidson, 1988; Crim, 1989). Flowable composites have been recommended for use in Class V cavities but it is also controversial because of its high rates of shrinkage. On the other hand, in the study comparing elastic moduli and leakage, the microfil had the least leakage (Rundle et al. 1997). Furthermore, in the 1996 survey of the Reality Editorial Team, microfills were the clear choice for abfraction lesions. The purpose of this study was to evaluate the microleakage of 6 composite resins (2 hybrids, 2 microfills, and 2 flowable composites) with and without load cycling. Notch-shaped Class V cavities were prepared on buccal surface of 180 extracted human upper premolars on cementum margin. The teeth were randomly divided into non-load cycling group (group 1) and load cycling group(group 2) of 90 teeth each. The experimental teeth of each group were randomly divided into 6 subgroups of 15 samples. All preparations were etched, and Single bond was applied. Preparations were restored with the following materials (n=15) : hybrid composite resin [Z250(3M Dental Products Inc. St.Paul, USA), Denfil(Vericom, Ahnyang, Korea)], microfil [Heliomolar RO(Vivadent, Schaan, Liechtenstein), Micronew(Bisco Inc. Schaumburg, IL, USA)], and flowable composite[AeliteFlo(Bisco Inc. Schaumburg, IL, USA), Revolution(Kerr Corp. Orange, CA, USA)]. Teeth of group 2 were subjected to occlusal load (100N for 50,000 cycles) using chewing simulator(MTS 858 Mini Bionix Ⅱ system, MTS Systems Corp., Minn, USA). All samples were coated with nail polish 1mm short of the restoration, placed in 2% methylene blue for 24 hours, and sectioned with a diamond wheel. Enamel and dentin/cementum margins were analyzed for microleakage on a sclale of 0 (no leakage) to 3 (3/3 of wall). Results were statistically analyzed by Kruskal-Wallis One way analysis, Mann-Whitney U-test, and Student-Newmann-Keuls method. (p=0.05) Results: 1. There was significantly less microleage in enamel margins than dentinal margins of all groups. (p<0.05) 2. There was no significant difference between six composite resin in enamel margin of group 1. 3. In dentin margin of group 1, flowable composite had more microleakage than others but not of significant differences. 4. There was no significant difference between six composite resin in enamel margin of group 2. 5. In dentin margin of group 2, the microleakage were R>A=H=M>D>Z. But there was no significant differences. 6. In enamel margins, load cycling did not affect the marginal microleakage in significant degree. 7. In dentin margins, load cycling did affect the marginal microleakage only in Revolution. (p<0.05)

신동훈,서성일,서석권 大韓産業醫學會 1999 대한직업환경의학회지 Vol.11 No.3

Objectives : This study was performed to investigate effects of cadmium and zinc on IL-6 secretion using human monocyte in a culture system. Methods : We have used trypan blue dye exclusion methods to examine the effect of cytotoxicity of CdCl₂, ZnCl₂in THP-1 cells. IL-6 was measured by the ELISA method in the cell culture supernatants and the expression of IL-6 mRNA was examined by reverse transcription-polymerase chain reaction. Results : IL-6 production by THP-1 cells were decreased at 0.1 mM cadmium concentration (p<0.05) and increased as zinc concentration increased. Zinc prevented cadmium-induced suppression of IL-6, and the addition of a chelating agent, EDTA, restores IL-6 secretion. The expression of IL-6 mRNA decreased at 0.08 mM and 0.1 mM cadmium concentrations. Conclusion : This results suggest that cadmium depressed production and gene expression of IL-6 in stimulated human monocytes, and zinc prevented cadmium-induced suppression of IL-6.

Price elasticity analysis of domestic air service supply is substantial to governments to establish civil air transport policy and to industries, both of carriage and manufacture, to determine production level. Considering the consistency of raw data and occupancy ratio of the routes to the total demands, three trunk lines (Seoul-Cheju v.v., Seoul-Pusan v.v., and Pusan-Cheju v.v.) are studied and the study period is for the 19 years between 1969, when airline were privatized, and 1987 when airline were discontinued to be monopoly. Price and cost elasticities of supply both of Seoul-Cheju v.v and Pusan-Cheju V.V. route are less than unitary. It means, first, air trips from and to Cheju include same properties of the demand for the commodities which are necessary in daily life and, second, the airline W e r s some costs partially to her international routes. Because there are various competitive and substitutive ground transports, the price and cost elasticity Q supply of Seoul-Pusan v.v. route are very high. Theses analyses implement governments to establish air transport policy : first, government renovates current air navigation and control system to decrease any cancellations and pauses af operations from the bad weather Cheju area Second, government keeps current occupancies o f carriages of each transport means between Seoul and Pusan.
