남창우,Sungjin Shin,Woojin Lee,Jae Ik Kim,Dae-Ryong Jung,Jongmin Kim,Seunghoon Nam,Sujin Byun,박병우 한국물리학회 2013 Current Applied Physics Vol.13 No.2

Transparent and conductive Ga-doped ZnO (ZnO:Ga) films were post-annealed after sputter deposition, and their structural and electrical properties were investigated. Post-annealing led to an improvement of crystallinity along the [001] direction, but did not change lateral grain size. Therefore, carrier concentration and electron mobility of films were analyzed as a function of crystallinity. The electrical parameters were obtained with both optical reflectance based on the Drude free-electron model and the Hall method, and similar tendencies were observed within the two methods. Even though the lowest resistivity was demonstrated by the film annealed at 550 ℃, the optimum values for carrier concentration and mobility were observed in films with different post-annealing temperatures.

남창우(Chang Woo Nam)(南昌祐),이명숙(Moung Suk Lee)(李明淑) 한국지방공기업학회 2007 한국지방공기업학회보 Vol.3 No.1

The purpose of this study is to examine the actual conditions of performance management in public sector and to suggest thereby the proper ways in applying the BSC, was originally developed for private firms, to performance management of public sector in Korea. First of all, customers of public sectors are hard to define. therefore, Customer perspective replace to performance perspective can be useful for policy making agencies. Second, structure perspectives, it requires that the application of the BSC is focused to program departments or sub-departments. Third, we propose that public organizations use flexibly and practically BSC approaches and their performance indicators according to characteristics of affairs and organizational independence. Fourth, the institutional setting requirements for the BSC should be made. The BSC should be harmonized with other existing tools for performance management. Especially, it need to integrate of information systems and link to existed evaluating systems. Lastly, We must consider the preconditions of the BSC and design the framework and the procedure as appropriate to public sector. 본 연구는 본래 민간부문에서 개발된 BSC 모형을 공공부문에의 도입 및 실천적 적용에 있어서 고려되어야 할 요인을 비판적 논의를 중심으로 살펴보고, 성공적 적용을 위한 시사점을 도출하는데 그 목적이 있다. 먼저, BSC 도입과 활용은 재무관점과 고객관점에서 적용상의 난제가 있다. 따라서 비교적 고객의 개념이 명확한 공기업이나, 집행기관의 경우에는 고객관점을 유지할 필요가 있으나, 정책형성을 주로 담당하는 공공부문의 경우에는 고객관점을 엄격히 적용하기 보다는 고객관점을 성과관점으로 대체하는 것이다. 둘째, 공공부문의 BSC 도입은 조직구조적 측면에서 이질적인 업무 및 종합적인 행정을 추진하는 대규모 조직보다는 동질적인 업무를 수행하는 사업조직 중심으로 확대될 필요가 있다. 셋째, 업무측면에 있어서 각 기관별, 사업별 BSC 도입목적을 명확하게 하고, 그 도입목적에 따라 계량적으로 측정할 수 있는 성과지표의 개발을 위한 충분한 연구가 선행되어야 한다. 넷째, 제도적 환경측면에 있어서 공공부문 BSC 구축은 공공부문 성과관리 과정과 조화를 이루어야 한다. 특히, 정보시스템과의 통합 및 기존 시스템과의 연계가 이루어져야 한다. 마지막으로 공공부문에 대한 BSC 도입은 이론적 차원과 실용적 차원에서 존재하는 괴리만큼 충분한 시간을 두고 검토과정을 거치면서 점진적으로 이루어질 필요가 있다.

국유재산의 관리체계실태와 효율적 개선방안

남창우(Nam Chang-Woo) 한국도시행정학회 2010 도시 행정 학보 Vol.23 No.4

There are problems that have been raised; not only the state-owned properties have not been treated effectively and economically in its managements and operations, but also utilized for public purpose and improving public welfare rationally. Even in current, the cases, state-owned properties are in unauthorized private possession or remaining as the dormant land, occur frequently and furthermore it is true that in terms of the national land management, there are no clear objectives for how to use them. However, with recent changes in domestic and international economic conditions, the use of state-owned properties and increasing profits by utilizing them began to show great interest and because of this new shifts for the state-owned properties have been tried. In this context, the purpose of this study is focusing on reviewing and resolving these accumulated problems relating to state-owned properties, and simultaneously providing alternatives to respond actively and positively with changes of new conditions. First, a paradigm shift of management is needed. Second, when the state-owned properties are used, “the payment principle”has to be applied. Third, through improving the division of state-owned property, expanding its functions as a “Bureau”or establishing a new “Agency”has to be required. Fourth, however, in pursuing the efficiency of state-owned properties’management, unlike the private development project which is able to pursue the profitability only, the state-owned property development project has to pursue profitability and publicness at the same time.

본 연구는 대학입학전형 유형과 대학 신입생의 공교육 및 사교육 경험 변인이 어떠한 관계를 가지는지에 대해서 탐색하는 것을 목적으로 하였다. 이러한 연구목적에 따라, 첫째, 대학입학전형과 사교육간의 관계를 살펴보았으며, 둘째, 대학입학전형에 따른 고교 재학 중 공교육 경험 및 만족도, 마지막으로 대학입학전형별 사교육 경험, 필요성 및 만족도 간의 차이를 살펴보았다. 연구대상은 부산광역시 소재 4년제 A대학교 2016학년도 신입생 중 1,151명과 2017학년도 신입생 중 982명이었으며, 설문조사를 통해 회수된 자료를 토대로 비교·분석하였다. 주요 결과는 다음과 같다. 첫째, A대학교 2016학년도 및 2017학년도 신입생은 고교 재학 중 참여한 공교육 활동에 대해 비교적 만족하는 것으로 나타났다. 둘째, 2016학년도 및 2017년도 수시전형 신입생들은 모두 공교육 중 진로진학 서비스에 대한 만족도가 높은 것으로 조사되었다. 셋째, 입학년도와 관계없이 사교육은 대학진학에 효과가 있으며, 특히 수학능력중심전형(정시)에서는 더욱 그러하다는 것을 알 수 있었다. 넷째, 입학년도와 관계없이 응답자의 80%이상이 고교 재학 중 사교육(유형, 비용, 시간 등)을 경험한 것으로 조사되었다. 이러한 연구결과는 다양한 입학전형을 공교육의 테두리에서 충분히 준비할 수 있도록 적합한 프로그램이 다양하게 개발 및 보급될 필요가 있으며, 학생 및 학부모의 사교육 의존도를 줄여나가기 위해서 다양한 제도적 장치가 마련되어야 할 것임을 시사하고 있다. The purpose of this study was to explore the relationship between the types of college admissions and the changes in the experiences of public education and private experiences of college freshmen. For the purpose of this study, first, we explored the relationships between college admission and private education, and secondly, we investigated the differences between the experiences and satisfaction of public education in high school according to college admission types, and finally private education experience by college admission types, necessity and satisfaction levels. The subject were 1,151 out of 2016 freshmen at A University in Busan metropolitan city and 982 out of 2017 freshmen. The collected data were compared and analyzed. The main results of this study were as follow. First, freshmen at A University were found to be relatively satisfied with the public education activities they had participated in while attending high school. Second, freshmen in both 2016 and 2017 were found to be highly satisfied with career development services during public education. Third, it was found that private education, regardless of the entrance school year is effective in advancing to college, especially in the College Scholastic Ability Test (regular admission). Fourth, regardless of the entrance school year, more than 80 percent of the subject private experiences(types, cost, time, and etc.) while attending at high schools. These findings need to be developed and supplied in a variety of suitable programs to ensure that various admission programs are fully prepared at the confines of public education. In addition, various institutional mechanisms will need to be planned to reduce dependence levels of students and parents about private education.
