  • In spite of the rapid development of the public network, the variety of network-based developments currently raises numerous risks factors regarding copyright violation, the prohibition and distribution of digital media utilization, safe communication, and network security. Among these problems, multimedia data tend to increase in the distributed network environment. Hence, most image information has been transmitted in the form of digitalization. Therefore, the need for multimedia contents protection must be addressed. This paper is focused on possible solutions for multimedia contents security in the public network in order to prevent data modification by non-owners and to ensure safe communication in the distributed network environment. Accordingly, the Orthogonal Forward Wavelet Transform-based Scalable Digital Watermarking technique is proposed in this paper.

  • 본 논문에서는 H공공도서관의 도서관 온라인 열람목록(OPAC) 시스템에 구축되어 있는 장서와 대출기록 및 이용자 데이터를 수집하여 이를 분석하고 그 결과를 공공도서관 운영에 적용할 수 있는 방안을 제시하였다. 수집된 자료는 H도서관에서 소장하고 있는 대출이 가능한 단행본 총 57,927권의 서지데이타와 11,871명의 이용자 데이터, 대출기록 27,145건이었다. 대출기록 분석 데이터에서 관계변수로 장서유형, 대출빈도, 대출권수와 대출횟수, 출판년도, 이용요인을 추출하여 상관계수와 비모수검증법 등의 다양한 통계적 기법으로 분석하였다.

  • 국가도서관통계시스템에서 요구하는 통계항목들은 이론적 견지에서 보면 도서관평가 또는 도서관운영 정책수립을 위해 필요한 데이터를 기반으로 한 항목들이라고 할 수 있다. 그러나 국가도서관통계시스템에서 요구하는 통계항목과 공공도서관현장에서 일반적으로 수집될 수 있는 통계항목들과는 차이가 있음을 알 수 있다. 따라서 공공도서관 평가로 활용되고 있는 국가도서관통계가 신뢰할 수 있는 또는 타당성이 있는 객관적 데이터인지를 알아보기 위하여, 공공도서관 현장에서 통계를 수집할 수 있는 근거자료인 도서관 업무(운영)일지의 항목들을 분석하고 아울러 통계의 자동수집이 가능한 도서관리 프로그램에 대한 공공도서관에서의 사용 현황을 조사하였다. 이 연구의 분석 자료는 향후 공공도서관 업무(운영)일지의 표준안 마련을 위한 기초 자료로 활용될 것이다.

  • Purpose: We present improvements to the Korean home visiting healthcare service based on analysis of Korean home visiting healthcare services considering recent sociodemographic changes and demands for healthcare services. Methods: This is a review study in which the results are derived through a literature review and data analysis. We collected data through a search of electronic databases, Google Scholar, and governmental websites. Results: Changes in Korean home visiting healthcare services are classified into four stages: 'introduction (1990-2000)', 'pilot project (2003-2006)', 'nationwide expansion (2007-2012)', 'various types (2013-2018)'. Korean home visiting healthcare service based on public health centers has achieved outcomes such as improved health behavior and health management, increased health management ability, and establishment of comprehensive healthcare infrastructure. Conclusion: In the future, the demand for home visiting healthcare service will increase steadily because of deepening social polarization, rapid aging of the population, and increases in chronic diseases. To improve health management and health equity, we suggest that Korean home visiting healthcare service will expand to all the people as a core public health service. It is necessary to establish a management team for various types of home visiting healthcare service in the public health center.

  • The purpose of this study is to define the difference in the self-concepts between the public and the private primary school students. The data were collected from March 16 to 20 in 1994. The objects of this study are the 5th graded primary school students, total 193, from the public (94 students) and private (99 students) schools located in Chong Ju city. The tool used for this study is SDQ (Self Description Questionnaire). The SDQ is a multidimensional instrument designed to measure seven aspects self-concept hypothesized in Shavelson's hierarchical model. The collected data were analyzed using descriptive statistics, chi-square test, t-test and 2-way ANOVA. The results of the study are as follows: 1. Between the public students and the private students there were no significant differences in the self-concept. 2. 2-way ANOVA using sex (male vs. female) and type of school (public vs. private) were performed. The boys had substantially higher self-concepts in physical ability and the nonacademic self concept. The girls tended to have higher self-concepts for the academic factors (except for Mathematies). 3. 2-way ANOVA using social stratification (upper vs. lower) and type of school (public vs. private) were performed. The upper classes tended to have higher self-concept for the academic factors. The social stratification and sample interactions were statistically no significant.

  • This study starts off by stating that the lack of awareness in the importance of reasonable and systematized layout in management facility is essentially working against building a quality public library. And that there is a merit in studying the spatial elements, its density, amount of needed space, and the likes to efficiently deal with present workings of the library which are becoming more dynamic and complicated. This paper seeks to embark on this study and also to provide a foundational data for research on management facility of the public library. The paper bases its research on 10 public libraries which are located in Seoul City and in Gyeonggi province, and are built after the year 2000. The paper focuses on the spatial distribution by section and allotment of management facility space in the library. Consequently, to find solutions or to suggest improvements on problems encountered, the paper introduces Japan's cases (4 recently-built public libraries) as a foreign case study. With foregoing domestic and foreign library case analyses, and the survey results of managerial staffs' demands, the paper seeks to provide basic data about management facility space and its floorplan of the public library. The paper bases its research on pubic libraries' management facilities, and expects to contribute to the efficient building of the public library in the future.

  • Purpose: The public sectors including government and public organizations have put an efforts to improve the quality of people's lives by providing enhanced services. The purpose of this paper is to investigate the factors that affect job attitude, job satisfaction, and job performance in the public sector, that are rarely examined by previous studies. Research Design, data, and methodology: The following research questions have been proposed: i) how do payroll system, personnel management system, cooperative working environment, and self-efficacy affect job attitude?; and ii) how does job attitude affect job satisfaction and performance? This paper used a survey through an online platform and collected data randomly from five classified public institutions. This study applied regression analysis and ANOVA. Results: This study found that cooperative working environment and self-efficacy had significant impacts on job attitude, while payroll system and personnel management system did not affect job attitude. Overall job attitude affected both job satisfaction and performance. Conclusions: The results provide policy implications to the public sector which factors should be considered to improve job attitude, job satisfaction, and job performance. The results also provide managerial implications how such efforts ultimately improve service quality to the citizens.

  • This paper empirically studies the effect of public procurement on small and medium-sized enterprises (SMEs) in the Republic of Korea using firm-level data. Public procurement, the purchase of goods and services from private firms by the public sector, is regarded as an important policy measure for providing support to firms, particularly SMEs. This study uses establishment-level panel data of the mining and manufacturing sectors from the Korean National Bureau of Statistics (Statistics Korea) and procurement history from the Korean Public Procurement Service to empirically estimate the effects of public procurement on firms' productivity (total factor productivity) and survivability. Using a propensity score matching estimation method, we find that participating firms showed higher productivity than non-participating ones in the control group only for the year of participation, that is, 2009. After two years, in 2011, they exhibited significantly lower productivity. In contrast, establishments that participated in public procurement for SMEs in 2009 were more likely to survive than those that did not do so in 2011. These results can be interpreted as the negative consequences of government intervention. The market's efficiency enhancement is hindered if underserving companies survive owing to government intervention but fail to improve efficiency.
