천연흑연은 단위구조가 탄소육각망평면이 평행하게 배열된 층상으로 전기전도도 및 윤활성이 우수하나 소수성이 매우 강하며, 표면화학적 목성이 거의 없기 때문에 다른 물질과 흡착이 쉽게 일어나지 않아 분산이 매우 어려운 물질이다. 따라서 본 연구에서는 제타전위를 이용하여 흑연에 ABDM을 흡착시켜 표면특성을 소수성에서 친수성으로 변화시키고 수중현탁액 중에서 흑연입자의 분산 메커니즘을 DLVO이론을 이용하여 설명하였다. 흑연의 제타전위가 22.5mV가 되도록 ABDM의 흡착량 (20mg/g) 및 조건 (PH 10에서 12시간 흡착)을 만족시키면 분산안정성 (T$_{1/2}$) 이 44.5시간인 고분산성 흑연 현탁액을 제조할 수 있다. The surface of natural graphite has not only good electrical conductivities and lubrication properties but also has strong hydrophobicity. There are no functional groups and chemical properties on it. It is difficult to join with any other ions and to disperse in aqueous system. In order to increase dispersion ability throughout modification of surface property, it is necessary to let graphite have some function on its surface by the adsorption of surfactant molecules. In this study, using zeta potential adsorbed surfactant molecules(ABDM) on graphite surface and its surface Properties turn hydrophobic into hydrophilic. The dispersing mechanism of graphite particles in aqueous system has been explained using the DLVO theory, It is concluded that the high dispersable graphite suspension of which dispersing stability$(T_{1/2})$ is 44.5 hours at pH 10 and 22.5mV zeta potential can be produced.

新藥事法上의 醫藥分業의 法理

金丙坤(Kim Byeong-Gon) 동아대학교 법학연구소 2007 東亞法學 Vol.- No.39

My purpose in this article is to study the ideology and the mechanism regarding the separation of medical practice and pharmacy. The key ideology of the separation is to protect people from harmful effect of medicine as medicine is possibly dangerous substance. Additional intention of the article is that all medical supplies should be administered without a certain profit motive by the prescriber as the use of medicine is not decided by consumer but by physicians or pharmacists. If medical supplies were decided with profit oriented purpose, it surely does harm to patients. The Separation System has been schemed because of such a possibility. Under the system the right and duty of a physician as a prescriber and a pharmacist as a medicine supplier is respectively given. The success of this Separation System I think depends on policies which rule out interfering from physician and pharmacist each other in the course of administration. More important step is that the prohibition of twofold ownership of medical care organization and pharmacy. In this regard the separation means the independence from each part of medical organization and pharmacy. Once the prescription is opened to the public by the separation, the high quality of medical care will be possible due to the exact and careful prescription of physician. Consequently medical democratization will be settled through the freedom of treatment information given to patient himself or herself. The article would like to enumerate or prove the key appropriateness and additional opinion on the separation of pharmacy from medical practice as follows: Ⅰ. The concept of Separation System: The separation means not only separation between prescribing and dispensing but one between medical practice and pharmacy. Ⅱ. The classification of medicine They classify prescribed medicine and non-prescribed medicine in America which classification method is the same as that of Korea. I have maintained that three-divided classification method like in Germany and England should be adopted. Ⅲ. The important ideology of Separation System: The System not only prevents medical abuse of people but also controls over application of all drugs and medicines. The Separation System is fundamentally twofold security system. The Reason is that the separation of pharmacy from medical practice is intended to take care of individual health and at the same time to derive a resonable medical cost by checking abuse of medicine. Ⅳ. pharmacists and physicians should work in collaboration to get a good outcome of medicinal treatment which otherwise would result in worse and unsatisfactory treatment. Ⅴ. Harmonization in practice under the Separation System: In practice of health care occasional harmonization between pharmacist and physician is required. That means both prescribing by pharmacist and dispensing by physician do not counter to the purpose of the Separation System. Ⅵ. I suggest to set up a kind of collaborating organization like an association by regional unit(community) which consists of physicians (doctors) and pharmacists. In addition to separation of prescriber's duty from pharmacist's, mutual discussion and check between them will bring about high quality medicine services and be able to diminish trial and error because the possible incidence of side effects and compliances of medicines should be confirmed through the collaborating system. Ⅶ. New pharmacy law is to be interpreted newly. In the new law pharmacist should be appraised not so much as a mere salesman as a pharmacist who fills a prescription and as a counsellor who helps patient with much medicine information. At any rate, in light of the fact that because of many exceptional articles in the laws of Japan it was unable to achieve the original purpose of separation system, korean laws concerning the above mentioned separation laws I think are going the other way.

The purpose of this paper is to investigate the effects of the interrelationship between the ownership and capital structure on the corporate value using 2SLS(2 stage least squares) regression method. The samples of this study are 228 Korean listed companies on the end of the year of 2000 and the period of analysis is 4 years from 1997 to 2000. The used data sets are pooling data during the 4 years. For the 2SLS analysis, three structural equation models are applied: ownership structure equation, capital structure equation, and corporate value equation. And the control variables are included firm size, risk, firm age, profitability, fixed asset ratio, and institute ownership. The analyzed results are as follows. The results of 2SLS method suggest that (i) the ownership structure strategy and capital structure policy are interrelated. (ii) Their interdependence effects on corporate value, especially, the ownership structure has the negative effect on the corporate value. But I can not find the effect of debt ratio on the corporate value.

新羅 中古期 支配 集團의 政治 過程에 대한 새로운 理解 Ⅰ

김병곤(Kim Byeong-Gon) 한국사학회 2004 史學硏究 Vol.- No.76

Until now a study on politics process of the ruling class in middle Silla period has focused on the conflict between king and novel class. But r have emphasized on the welfare and peace for state.<br/> In this point of view, what Sa Ryun(舍輪), the second son of King Jin Hung(眞與王) took the throne is due to King Jin Hung's help. In addition, Sa Ryun had a legitimacy of succession to the throne. And Geo Chill Boo(居柒夫) who controlled politics on King Jin Ji(眞智王) era was a favorite retainer of King Jin Hung. So he could work as a assistance of King Jin Ji. Despite of Sang dae dung(上大等) Geo Chill Boo's help, King Jin Ji who was lack of political ability was dethroned by d}e noble(國人) because of incompetency and lewdness(政亂荒淫).<br/> After the dethrone of King Jin Ji, Baek Jeong(白淨), grandson of King Jin Jj acceded to the throne as King Jin Pyeong(眞平王). This work has understood as a challenge of royal authority. But this work can be understood as achievement of anti-King Jin Ji powers for the public peace, So in spite of young King Jin Pyeong's throne, King Jin Pyeong could reinforce his power and build new government office on the basis of his supporters, The study on the development of politics need approach of the various viewpoint in middle Silla period, Through this study, we can understand this period.

Recently, following the development of FinTech technology that combines finance and information and communication technology, the need and social demands for a block chain technology-based trading system have increased significantly. In this study, a research model was developed and hypothesized through literature research on the concept of block chain technology, the technology acceptance model, and the unified theory of acceptance and use of technology. The research theories were tested by collecting data through surveys and analyzing the collected data. This study conducted empirical research to identify the factors influencing the user acceptance intention and utilization behavior of the block chain technology in introducing the block chain technology. First, factors affecting the acceptance intention of the blockchain user were performance expectation, effort expectation, social impact, and blockchain transparency variables. Second, the facilitation conditions and stakeholder confidence variables were analyzed as factors that did not affect the acceptability of the blockchain users. Third, variables such as blockchain transparency, stakeholder trust and intention of acceptance are factors that affect the usage behavior of the blockchain. Fourth, it was confirmed that the acceptance intention had a very high explanatory power on usage behavior of Blockchain technology.

우리 나라 주식시장에서 투자지표로서 경제적 부가가치(EVA)의 유용성에 관한 연구

구맹회,김병곤,Gu, Maeng-Hoi,Kim, Byeong-Gon 한국재무관리학회 1998 財務管理論叢 Vol.4 No.1

미국의 증권시장에서는 EVA가 주요한 주자지표로 주목을 받고 있다. 그동안 주요 투자지표로 사용되던 EPS, ROA, ROE, PER 등의 회계적 이익지표들에 비해 EVA의 활용도가 점차 높아지고 있다. 우리 나라에서도 투자지표로서, 경영관리지표로서의 활용 가능성에 대해 관심이 증가하고 있다. 본 연구에서는 우리 나라 주식시장에서 EVA가 유용한 투자지표로 활용될 수 있는가를 살펴보고자 하였다. 1991년부터 1995년의 분석기간에 걸쳐 첫째, 주당EVA가 회계적 이익지표보다 주식수익률을 더 잘 설명하는가, 둘째, 주당EVA가 높은 기업이 더 높은 초과수익률을 실현하는가, 셋째, 주당EVA는 개별 종목 초과수익률의 선행지표로 활용될 수 있는가를 EPS, ROA, ROE, PER 등의 회계적 이익지표와 비교하여 분석하였다. 분석결과 첫째, 우리 나라 주식시장에서 주식수익률은 주당EVA보다 회계적 이익지표인 EPS, ROA, ROE가 더 잘 설명하는 것으로 나타났다. 둘째, EPS, ROA, ROE를 기준으로 포트폴리오를 구성하는 경우 유의적인 초과수익률을 획득할 수 있는 것으로 나타난다. 주방EVA를 기준으로 포트폴리오를 구성하는 경우에는 3월 이후에 포트폴리오간 유의적인 초과수익률 차이가 발생하여 초과수익률 획득이 가능한 것으로 나타났다. 셋째, 주당EVA, EPS, ROA 등은 초과수익률에 대해 동행적 투자지표로 유용하고, ROE는 동행적 지표와 선행적 지표로 모두 유용하고, PER는 선행지표로 유용한 것으로 나타났다. 이와 같은 분석결과는 우리 나라 주식시장에서 EVA는 회계적 이익지표인 EPS, ROA, ROE, PER보다 더 우월한 투자지표라고 말하기는 어렵지만, 회계적 이익지표와 보완적으로 활용하는 경우에는 유용한 투자지표로 활용될 수 있음을 나타내고 있다.
