Bifunctional catalysts metals on supported on Y zeolite exchanged by rare-earth ion (RE*), have high catalystic activity for the synthesis of adamantane from tetrahydrocyclopentadiene(TCD) in the presence of hydrogen and hydrogen chloride. These catalysts were prepared by the impregnation of metal salts with RE-Y zeolite. Their activity was measured by the batch reactor system. The TCD conversion consists of two reactions, the rearrangement of TCD to adamantane and hydrocracking to ring opening products(C??H?? isomer). No tarry materials were produced in the TCD conversion over bifunctional catalysts in the presence of hydrogen. The activity of metals supported on RE-Y for hydrocracking of TCD varied in proportion to the %d character of the metals. While for the rearrangement, it was independent of the %d character of the metals. In the case of a binary system of platinium and Rhenium the maximum activity for both reaction was observed at Re/(re+Pt) = 0.24. Furthermore poisoning by atomic sulfure on a bifunctional catalyst, the activity for the hydrocracking of TCD was depressed.

공무원 핵심역량강화를 위한 민·관의 교육훈련 협력방향

김판석 한국정책학회 2002 韓國政策學會報 Vol.11 No.1

본 논문의 목적은 정부의 경쟁력을 향상시키기 위해 공무원의 역량을 강화하는 차원에서 민·관의 교육훈련 협력방향을 모색하는데 있다. 따라서 본 논문은 공무원교육훈련 전반에 관한 것이 아니고, 교육훈련을 통해 공무원의 역량을 강화하기 위한 하나의 방안으로서 민·관의 교육훈련기관간의 상호 유익한 협력방향을 제시하는 것이 주된 목적이다. 공무원 교육훈련과 관련된 여러 이슈를 한정된 원고에서 모두 다루기는 어렵다. 따라서 본 원고에서는 공무원의 역량에 대한 개념과 외국사례 등을 정리하여 다소 비중을 두어 소개한 후에 본 논문의 주제인 민·관의 교육훈련기관간 협력현황과 문제점 그리고 개선방향들을 차례로 고찰해보기로 한다. The purpose of this paper is to promote cooperation between governmental and corporate training institutions for improving the competence of government employees. This paper does not intend to discuss the overall training issues in general. This paper cannot deal with all the relevant issues in human resource development due to various limitations. Instead, it attempts to promote cooperation building between governmental and corporate training institutions as well as competence building. Up until now, governmental training institutions have received serious criticism both from practitioners and academics for their lack of effectiveness in training. Recently, competence building has gained attention from both government and business as an alternative framework for human resource development. So this paper first will discuss the concept and characteristics of competence in a comparative perspective. After that, facts and problems of cooperation between governmental and corporate training institutions will be reviewed, followed by discussion on promotion strategies through competence building and cooperation between government and business.

金大中政府의 政府改革過程 硏究

김판석 서울대학교 행정대학원 2000 行政論叢 Vol.38 No.2

본 논문에서는 공공부문개혁(public sector reform)의 주요 과제 중에서 공기업과 재정개혁을 제외한 정부개혁의 과정 (government reform process)을 연구대상으로 하였으며, 개혁과제는 공공부문 중에서도 중앙정부와 지방자치단체에서 추진되었던 것들을 중심으로 연구하였다. 개혁의 성패와 관련하여 설문조사를 통한 계량적 평가방법을 자주 활용하지만, 본 연구는 그러한 방법을 택하지 않고, 개혁과정자체를 중심으로 연구하였다. 따라서 본 연구는 그 동안의 개혁방향, 과제선정, 과제추진, 개혁추진체계, 개혁제약요소, 개혁관리, 개혁추진전략, 개혁 제약요소, 그리고 향후 추진방향 등을 중심으로 가능한 한 객관적 시각에서 살펴보고 개혁관리상의 정책적 함의 등을 제시하는 순서로 연구를 진행하였다.

MnO_4^--(COOH)_2 redox system에 의해 개시된 methyl methacrylate의 중합을 질소 분위기에서 35±0.2℃의 aqueous media내에서 연구하였다. 중합속도는 낮은 활성제 농도(2.0×10^-3-7.5×10^-3M)에는 무관하지만 그 이상의 높은 농도에서는 속도가 감소함을 알 수 있었다. 중합의 개시속도는 낮은 촉매농도(0.5×10^-5-2.0×10^-5M)에서는 반응차수가 1차이었으며 높은 촉매 농도(4.0×10^-5-3.2×10^-4M)에서는 대략 0.5차 임을 알았다. 또한 개시속도는 낮은 단량체 농도(2.0×10^-2-10.4×10^-2M)에서는 비례하여 증가하나 10.4×10^-2M농도 이상에서는 오히려 감소하였다. 온도가 30∼45℃ 범위 내에서는 온도가 상승함에 따라 개시속도는 증가하지만 최대 중합율은 감소하였고, 25∼45℃의 온도 범위에서 총괄 활성화 에너지는 8.2Kcal/mole임을 알았다. 유기용매인 알콜과 Salts의 첨가는 중합속도를 감소시켰으나 MnSO_4는 개시속도를 증가시키는 반면에 EDTA는 최대 중합율을 상당히 증가시켰다. 그리고 FeCl_3·6H_2O와 CuCi_2·2H_2O는 중합 억제력이 아주 크다는 것을 알 수 있었다. The polymerization of methyl methacrylate initiated by permanganate-oxalic acid redox pair has been studied in aqueous media at 35±0.2℃ in nitrogen atmosphere. The rate of polymerization is independent of activator concentration (2.0×10^-3 to 7.5×10^-3M), but the further increase of the concentration decrease the rate. The initial rate of polymerization has been found to be proportional to nearly the first power of low catalyst concentration (0.5×10^-5 to 2.0×10^-5M) and 0.55 power of high catalyst concentration (4.0×10^-5 to 3.2×10^-4M). The initial rate increases linearly at low monomer concentration (2.0×10^-2 to 10.4×10^-2M) but decreases at higher monomer concentration (above 10.4×10^-2M). The initial rate increases as the temprature increases from 30℃ to 45℃, while the maximum conversion decreases. The overall energy of activation has been found to be about 8.2 Kcal/mole within the temperature range 25-45℃. Organic solvent (alcohols) and salt (KCI) decrease the rate of polymerization but MnSO_5 increases the initial rate and complexing agent EDTA increases the maximum conversion to a considerable extent. FeCl_3·6H_2O and CuCi_2·2H_2O have been found to be polymerization retarders.

한국의 지방정부는 행정수요의 변화에 능동적으로 대처하고, 높은 생산성과 세계경쟁력을 갖춘 정부로의 변화를 요청 받고 있다. 특히 지방분권화에 따른 내부역량 강화 차원에서 지방 정부는 인력관리의 효율성 제고와 유연하고 탄력적인 인력관리를 위하여 인력관리 부문의 개혁을 지속적으로 추진하는 과정에 있다. 행정서비스의 효율적인 운영의 주체는 사람이므로 지방정부의 생산성 향상을 위한 지방공무원의 전문화, 능력발전, 인사교류 등 '사람을 다루는 인사관리'가 주요한 개혁과제로 인식되고 있다. 국가적 차원에서 한정된 인적자원을 보다 효율적으로 운영하기 위해서 정부간 또는 정무-민간부문간에 보다 활발한 인적자원 교류의 필요성이 대두되고 있다. 그러나 민선자치단체장 이후 지방정부의 인사교류가 활발하게 이루어 지고 있지 않아 국가 전체적인 측면에서 인력활용의 극대화를 도모하지 못하고 있는 실정이다. 지역할거주의와 자기조직제일주의 그리고 동류집중(inbreeding) 등을 줄이기 위해서는 교류를 촉진해야 한다. 따라서 본 연구의 목적은 지방자치단체간 인사교류의 현황과 문제점을 살펴보고, 지방자치단체간 인사교류의 활성화를 위한 개선방안을 모색하는데 있다. In the last decade, Korea has undergone considerable socio-political change. The Korean citizen is now exercising newly gained democratic freedoms including making demands upon Korean local governments are further compelled to reform systems and practices in order to improve the nation's overall global competitiveness. This paper will argue that the primary focus of improving local governments should be to improve the competencies of human capital. For example, local governments need to improve the efficiency and flexibility of human resource management through professionalization of the work force and structured human resource development including personnel exchanges. In order to promote mobility and flexibility of human resources, this paper examines personnel exchange practices in Korean local governments. There might be various reasons for underdevelopment of personnel exchange in Korea, but one reason for the fact that personnel exchange has not been practiced actively is that since the mid-1990s the chief executive officers of Korean local governments have become elected positions. Therefore, newly elected mayors and governors have been reluctant to deploy their most competent employees to other regions for fear the services upon which their re-election hopes depend might deteriorate. This study first reviews existing problems of personnel exchange in Korean local governments, and then suggests possible policy alternatives in order to promote personnel exchanges between the local governments and even suggest exchanges from other sectors.

Experiments on forced convection of air for the cylindrical pin-fin arrays were performed for a Reynolds number range of 210.5 to 1052.6. The effect of interfin spacing, ?//d×??/d=2×2 and 3×3, was investigated for in-line and staggered pin-fin arrays. Data were also obtained for changing of the pin-fin height. The experimental data were utilized to compare with the values calculated for the tube banks. The results were as follows; 1) The average heat transfer coefficients for staggered array are higher than those for in-line array. Those for both pin-fin arrays more affected are more affected in Reynolds number than tube banks, and lower pin-fin arrays. 2)The heat-transfer rate for staggered array in the same interfin spacing are higher than those for in-line array, and the heat transferred increases as the spacing of pin-fins becomes narrow. 3)The fin efficiency of pin-fin arrays decreases as the Reynolds number increase, and this situation is more in lower pin-fin arrays. The fin efficiency for in-line arrays is higher than that for staggered arrays.

Over the past 20 years, research on students' conceptual development of science concepts has begun to inform educators about the roles that prior knowledge and experiences play in the development of conceptual understandings. Whereas many initial studies focused on identifying and cataloging naive of misconceptions, more recent research has focused on how student concept development research can inform teaching practice and curriculum design. In this study, we investigated children's (ages 11∼12) spontaneously constructed or naive understanding of the particulate nature of matter prior to any formal instruction in the domain. Thirty students were interviewed concerning their understanding of the macroscopic and microscopic properties of the states of matter(solid, liquid, and gas), as well as their macro/microscopic understanding of phase changes and dissolving. Children expressed ideas about states of matter which were categorized as macrocontinuous, macroparticulate, or microparticulate. Furthermore, a substantial number of the children provided explanations of properties and processes which were consistent with those beliefs. These children's beliefs about matter were not fully and consistently developed across the spectrum of substances from continuous solids to particulate solids to liquids to gases. We speculate that children first develop local frameworks particular to different classes of substances and then slowly expand these frameworks to include a wide range of substances and their properties as well as such processes as melting and freezing.
