박용찬,Takeo Kajishima 한국자원공학회 2010 Geosystem engineering Vol.13 No.4
Traditionally, the gas-lift pump has been used to lift corrosive or toxic liquid due to its simple structure and maintenance. It is also considered as a technically feasible system for the development of deep-ocean minerals and as a means to sequestrate CO2 gas into the ocean. Donor-cell scheme or Forward-Time and Backward- Space (FTBS), which is commonly used in solving advection equation such an air-lift system, is very stable but causes numerical diffusion. In order to reduce numerical diffusion or dissipation by the first-order upwind scheme, CIP (Cubic-Interpolated Propagation/Constrained Interpolation Profile) has been applied to bubble and slug flows in a gas-lift pumping system. The GLAD (Gas-Lift Advanced Dissolution) model using CIP method were validated by comparison with gas-liquid two-phase experiments and the effectiveness of the CIP method over the typical one has been demonstrated from the simulation of gas-liquid two-phase slug flow.

박용찬 대구대학교 (한사대학) 사회복지연구소 1980 社會福祉硏究 Vol.8 No.-
In realizing a sound welfare state, industrial accident insurance occupies an important function and is essencial to our present social insurance system. The first objective of industrial accident insurance is to insure the laborer, while at the same time, reducing the financial risk to the industrialist, and, in addition, attempts to increase productivity. This paper concerns the significance from the social security view, deals with the development process of industrial accident compensation according to its historical background, and views the position that industrial accident compensation now holds. Then this essay concerns the industrial accident insurance system and social insurance and researches their present conditions. Finally, in this study, an attempt is made to grasp the problems, and research into some effective management plans.

Pluralism과 Elitism의 理論的考察 : 한국에 적합한 理論的模型의 모색
朴庸燦 서울市立大學校 1985 論文集 Vol.19 No.2
The meaning of pluralism can be condensed into two phrases, that is, "the inferplay of diverse political groups" and "diffusion of power". The classical pluralist structure is a tri-level arrangement in which a congeries of voluntary associations stand between the masses and the state. Modern version of pluralism is elite-pluralism, in which the need for political elites to make societal decisions at some distance from the masses is recognized. The validity of the pluralist model is questionable on several grounds. The fundamental premise of the elite model of societal power is the prevalence of rule by the few. Classical elite theorists Pareto and Mosca explain the development of elite rule as inevitable. But radical elitists don't see elites as either inevitable or necessarily functional. The power elite is viewed as retaining its power manipulation of the masses. Despite its compelling thesis, elite theory leaves certain questions unanswered. These questions are related to elite inevitability, elite cohesiveness, elite-mass relations, and the place of the masses. In spite of these questions, elite theory remains a forceful description of political structure and behavior in modern societies. This article is designed to apply the theory of elitism and pluralism in Korean society. In conclusion, elitism may be suitable for Korean society, particulary, concept of Mills' power elite and Mosca's elite change.

朴庸燦 서울市立大學校 1991 論文集 Vol.25 No.-
Welfare Policies are closely related and influenced by social values on which a society is built up. The current study first explores the relationship between welfare policies and efficiency-equity, and then seeks to find the view on efficiency and equity revealed in Korea's welfare policies. Without analyzing social values preferred by a specific society, it is hard to make any welfare policy effective and also hard to achieve the fundamental goals of the welfare policy. Chapter 1 explains purposed and boundaries, chapter 2 explores the relationships between social welfare policies and efficiency-equity. Most of all, this study focuses on competing social values, all of which are important in making welfare policies. Chapter 3 discusses social values-economic efficiency versus social equity-with regard to welfare policies. A literature review of the trade-offs among competing values is presented. Chapter 4 empirically analyzed the trade-offs between efficiency and equity found in a variety of Korean welfare policies, Chapter 5 summarizes the characteristics of Korean welfare policies. This study reveals that the level of welfare in Korea not anly falls behind that of developed countries but also does behind the welfare in the countries whose economic environments are similar to those in Korea. This might be a result of Korean national policies which have been putting more weights on the economic development policies than on the welfare policies. In other word, it is resulted from the fact that Korean government puts more values on economic efficiency than on social equity.

The Clean Development Mechanism (CDM) established under the Kyoto Protocol is one of the cooperative mechanisms to assist GHG (Green House Gas) reduction and promote environmentally friendly investment into developing countries from industrialized country governments and businesses. The purpose of this paper is to provide an overview of the CDM methodologies in mining sector and a way to use CDM in the country and overseas. Then CCS (Carbon capture and storage) project will be introduced which is a hot issue where it can be considered as CDM at the Conference of the Parties to the Climate Change Convention. 교토의정서에 명시된 청정개발체제(CDM)은 선진국 정부 및 기업들이 개도국에 투자함으로서 온실가스 저감 및 환경친화적 투자를 촉진하는 협력 메커니즘의 하나이다. 본 논문에서는 CDM 사업영역 중 채광분야(mining sector)에서 우선, 승인된 CDM 방법론과 국내 산업동향 및 활용방안을 살펴보고 다음으로 기후변화당사국회의에서 CDM 사업으로 인정하는 문제에 대해 논의중인 CCS 사업에 대해 소개하고자 한다.서 론
