신공공관리론 기반의 정부개혁 패러다임에 따라 공공부문이 전문화되어 행정의 역할이 확대되고 그 기능이 세분화하면서 고도의 전문성과 자격을 요구하는 직무 수요가 증가하고 있다. 한편 정보통신기술의 급속한 발달에 따라 공공행정업무를 통해 생산되는 데이터도 큰 폭으로 증가하여 공공부문 데이터 관리 분야가 확장되고 그 중요성 또한 커지고 있다. 하지만 데이터 관리직무에 대한 개념화 및 체계적 연구가 매우 부족한 현실이며 관련 법령에서도 직무의 구체적 정의나 담당 인력에 대한 구체적 자격 요건을 찾아보기 어렵다. 본 연구는 공공부문의 전문화와 이에 따라 요구되는 직무의 전문성에 대한 선행연구 검토를 통해 전문성의 개념적 차원을 확인하고 이를 토대로 공공부문 데이터 관리 직무의 유형과 자격 요건을 분석하였다. 공직 전문화에 토대를 둔 전문성의 하위 차원 중 전문직 기반 인사관리와 통제에 초점을 두고 관련 법령 및 업무 지침, 채용 공고에 나타난 직무의 내용을 분석한 결과 첫째, 공공부문 데이터 관리직무에 대한 책임자 및 실무담당자의 직무 역할 및 책임의 한계 구분이 모호한 것으로 나타났다. 둘째, 업무 지침 및 실무 매뉴얼에 데이터 생애주기의 각 단계별 직무 내용이 균등하게 반영되지 않고 사후 품질관리단계에만 중점을 두고 있었다. 셋째, 공공부문 데이터 관리직무 및 담당 인력에 대한 자격 요건의 구체적 정의가 확립되지 않았다. 따라서 법령 및 지침에 직무와 담당자의 역할 및 책임 수준과 데이터 생애주기의 단계별 내용을 구체적으로 반영하고 장기적 관점에서 직무 전문성 제고를 위한 직무분석 및 평가가 선행되어야 할 것이다.

This study aims to provide public sectors with eco-efficiency information. To implement the purposes of the study, environmental and economic variables of Eco-Efficiency were identified through decision tree model, then the relative Eco-Efficiencies of 243 public sectors were evaluated through input-oriented DEA (Data Envelopment Analysis) model. Specifically, the amount of public purchasing per a staff and the amount of energy use per a staff were considered as input factors. Sales per a staff was considered as output factor. The result shows that most of the public sectors (94.2%) were evaluated as "inefficient" taking into consideration of average value, 0.501 from market-based public corporations, 0.288 from local public corporations, 0.28 from quasi-market-based public corporations, 0.269 from fund-management-based quasi-governmental institutions, 0.09 from non-classified public institutions, and 0.078 from commissioned-service-based quasi-governmental institutions. Furthermore, it is possible to establish a plan for internal Eco-Efficiency improvement based on information of the reference set. In order to improve the Eco-Efficiency in the public sectors in the long term, environmental impacts of the overall public sectors' operations (e.g., energy saving, water saving, waste reduction, and purchasing of green products) needs to be properly proposed in consideration of BSC (Balanced Scorecard) indicators of public sectors.

Purpose : The purpose of this study is to understand the experiences of nursing students in clinical practice at a public health center through their self- reflections. Subjects : The 110 students in the 3rd year, practice at two public health centers in city P and city K. From the110, 53 male and female university students who practice in city K were selected to participate : 11males (20.8 %) and 42 females (79.2 %). Methods : The data analyzed were the self-reflections regarding the clinical practice. Results : These data indicate that : most of the participants now believe that public health centers provide many more services to the community than they previously knew about. They rate the public health center's programs highly, and want to be community health nurses. For the first time, they realize that the work of public health nurses is very important. In particular they note that their emotions while at the public health center differ significantly from when they work at the other. The environment in the public health center makes them feel more comfortable and less stressed. Generally, they are satisfied with their practice at the public health center. Conclusion : On the basis of these findings, the following recommendations can be made. Experience at public health centers is an important part of nursing students' education. I suggest that research on nursing students' experiences while practicing at the public health center should expand to include research methods other than the analysis of their reflection journals, In addition a follow-up study of experiences while practicing at the public health center should be attempted of self-reflections.

The writer obtained a Conclusion through this thesis as follows: First : There a n.0, ppeared that users, Cognition degree for librarian's Social status is very high. As it were, response for questioning about librarian's scholarly attainments and business type is almost accurate that we anticipate the expectation value for the librarian is very high. Second : The satisfaction degree of information services acquired by the users through public library was very skeptic. Due to the poorness of information media that we wish, and deterioration of data, it losed its qualification as a creation organization for the true information, but lots of people emphasized their opinion it only role as a "study room". Third : A questioning about librarian"s assiduity in the public library, there are lots of users Complain. Main factor of that dissatisfaction is Unkindness, and business like(duplicated) assiduity. Not only this but main desire to the public library in pusan down town by the users is also a n.0, ppeared as Kind Service. Fourth : General Controversial points in public libraries in pusan area indicated by the users who responded to the subjective questions are poor data, lack of kind service attitude and poor facilities.oor facilities.

Every year governments spend their national budget on public health in order to reduce financial burden of individuals on health. Although it has been widely believed that the increase of public expenditure on health decreases private health expenditure, it has not been proved by analysis with real data. For better understanding, we conducted an empirical study on the real data of 17 OECD countries-Australia, Austria, Canada, Denmark, Finland, Germany, Iceland, Ireland, Japan, Korea, New Zealand, Norway, Portugal, Spain, Sweden, the United Kingdom, and the United States. The panel Granger-causality test is used to verify the cause-and-effect relationship between the two expenditures. As a result, public expenditure on health has a 3 to 4 year-lagged negative effect on private health expenditure in the cases of the 16 countries except for the United States.

The purpose of this study was to identify the changes in transportation expenditure patterns of urban households during 1985-19o8. The data were drawn from 'Annual Report on the family Income and Expenditure Survey' by National Statistical Office, Republic of Korea. For data analysis, frequency, percentile, mean, and multiple regression analysis were utilized by the SAS window program. The results of this study were as follows; Frist, the levels of public transportation expenditure showed increasing trend, whereas the portions of public transportation expenditure have showed decreasing trend during 1985-1998. And both the level and the portion of private transportation expenditure showed increasing trends during 1985-1998. Second, the marginal propensities to consume of public transportation have decreased, whereas the marginal propensities to consume of private transportation have increased during 1985-1998. Third, income elasticities of public transportation showed decreasing trend during 1985-1998, impling that consumers have less demand public transportation with increasing income. And income elasticities of private transportation showed increasing trend till 1993, and then showed decreasing trend till 1998, impling that consumers have perceived the car as one of necessary goods rather than luxury goods gradually since 1993.

Assessing local government performance has become a crucial issue in recent years. This paper addresses the satisfaction level of local government public service, which is defined as a degree of the results or the impacts of the local government public service delivery on the citizen's needs, demands and expectations. The satisfaction level of local government public service can improve decisions made by local government managers, and enhance accountability of local government to the citizens they serve. This study focuses especially on the various aspects of administrative systems in a local government and developed a systematic survey for their performance. Explanations for the evaluation items and the analysis of survey are discussed throughout the paper.

In this paper, a new asymmetric public key cryptography based on the modified RSA algorithm is proposed by using logic-based optical processing. The proposed asymmetric public key algorithm is realized into an optical schematic, where AND, OR and XOR logic operations are implemented by using free space digital optics architecture. Schematically, the proposed optical configuration has an advantage of generating the public keys simultaneously. Another advantage is that the suggested optical setup can also be used for message encryption and decryption by simply replacing data inputs of SLMs in the optical configuration. The last merit is that the optical configuration has a 2-D array data format which can increase the key length easily. This can provide longer 2-D key length resulting in a higher security cryptosystem than the conventional 1-D key length cryptosystem. Results of numerical simulation and differential cryptanalysis are presented to verify that the proposed method shows the effectiveness in the optical asymmetric cryptographic system.
