Librarian certification in Korea is issued by the LIS Departments, the Academy of Librarianship, and the Academic Credit Bank system; however, it has been pointed out that there is a limit to how much these nurture high quality librarians, because the education quality and contents varies from education institutions and there is no verification method for certification issued by educational programs. Therefore, this study investigated certification systems of academic or training programs that are conducted at home and abroad, analyzed how the certification systems are oriented, what the purpose and criteria of the certification systems are, and what the content of assessment is. As a result of this investigation, several areas needing change were identified which if adopted can improve the system. These included making amendments to the library laws related to the certification system, substantially revising the relevant enforcement ordinance, making changes to the selection of the Certification authority, establishing certification standards and procedures, developing contents related to document examination and due diligence audits, rating the effects of the certification system, and setting standards. Improving the Librarian Certification System has been discussed over the past 20 years and should not be delayed any longer because of the university structural reform of the current government, the rapid rise of the qualified librarians, decreasing employment due to the human resources supply and demand imbalances, all of which has resulted in a survival crisis of four-year Department of Library and Information Science.

This research aims at measuring images density of according to DAP(dose area product), and suggesting the need to quality control of exposure dose. When tube voltage was fixed as 80 kVp and tube current was set as 1, 25, 50, 80, and 100 mAs, with the increase of DAP from 25 mAs to 50 mAs, the dose also rose 1.88 times as much as before, and with the increase from 50 mAs to 100 mAs, it got 2.05 time higher than before. However, the images density obtained as film grew as much as 48% with the increase from 25 mAs to 50 mAs, and 29% with the increase from 50 mAs to 100 mAs. In addition, it has been found out that the higher the DR images density got from 25 mAs to 50 mAs, the bigger it became by 12%, and that it got bigger by 30% with the increase from 50 mAs to 100 mAs. In other words, the differences in the image density by the increase of the dose with the digital imaging equipment in a proper condition was proved to be less than in the film images. Based on the results of this research, medical institutions using a digital imaging equipment are expected to be able to reduce exposure dose of each region of interest than now through the quality control of radiation dose.

Digital imaging for general rediography has many advantages over the film/screen systems, including a wider dynamic range and the ability to manipulate the images produced. The wider range means that acceptable images may by acquired at a range of dose levels, and therefore repeat exposures can be reduced. Digital imaging can result in the over use of radiation, however, because there is a tendency can be reduced. Digital imaging can result in the over use of radiation, however, because there is a tendency for images to be acquired at too high a dose. We investigated the actual exposure dose conditions on general radiography and a questionnaire survey was conducted with radiotechnologiest at medical institutions using digital radiology system. As a results, the dose of exposure was not controlled with patient's figure and dose optimization but was controlled by worker's convenience and image quality. Radio-technologiests often set up the exposure dose regardless of patient figure and body part to be examined. Many organizations, such as the International Commission on Radiological Protection, recommend to keep the dose as low as possible. In addition, they strongly recommend to keep the optimal but minimal dosage by proper training programs and constant quality control, including frequent patient dose evaluations and education.

The importance of knowledge and information is ever increasing. The ingredients of the customer value of the information offered for free by the public information organizations are different from those of the ordinary products or services. This study aims to identify the factors which affect the information customer value and the job performance of the R&D managers who use national R&D information service(NTIS). The results show the quality of information service and the perception of services organizations have significant positive effect on customer value. In addition, the customer value have significant influence on the job performance. Meanwhile, the perception of information organizations have not effect on the job performance. Regarding the moderating effect of the information using environment, the results are as follows: the information using environment moderates the relationship between the information service quality and between the customer value and the perception of information organizations, and the relationship between the customer value and the job performance, but does not moderate the relationship between the perception of information services organizations and the job performance. According to the research results, we proposed several implications to foster the customer value management in the field of public information as well as future research directions.

In the context of open science, data sharing and reuse are becoming important researchers' activities. Among the discussions about data sharing and reuse, data journals and data papers shows visible results. Data journals are published in many academic fields, and the number of papers is increasing. Unlike the data itself, data papers contain activities that cite and receive citations, thus creating their own intellectual structures. This study analyzed 14 data journals indexed by Web of Science, 6,086 data papers and 84,908 cited references to examine the intellectual structure of data journals and data papers in academic community. Along with the author's details, the co-citation analysis and bibliographic coupling analysis were visualized in network to identify the detailed subject areas. The results of the analysis show that the frequent authors, affiliated institutions, and countries are different from that of traditional journal papers. These results can be interpreted as mainly because the authors who can easily produce data publish data papers. In both co-citation and bibliographic analysis, analytical tools, databases, and genome composition were the main subtopic areas. The co-citation analysis resulted in nine clusters, with specific subject areas being water quality and climate. The bibliographic analysis consisted of a total of 27 components, and detailed subject areas such as ocean and atmosphere were identified in addition to water quality and climate. Notably, the subject areas of the social sciences have also emerged.

This study was undertaken to investigate the general characteristics of students, which include the degree of satisfaction, motives of admission, the recognition of advantages and disadvantages, opinion of students on self-directed learning, and planning and anticipatory effects after graduation. Data was collected through a questionnaire survey over a period of four months, from May 1997 to August 1997. The subjects used for this study consisted of 322 RN students sampled from six RN-to-BSN programs in Korea using the census sampling method. Statistical methods employed for this study included discriptive statistics, M ANOVA, and F-test. The results of the study are as follows 1. The RN students' motives of admission to RN-to-BSN programs were ‘for personal advancement’, ‘to earn a BSN degree’, and ‘for professional development’ in this order. 2. The RN students' responses to the advantages of RN-to-BSN programs were ‘acquisition of new knowledge and a BSN degree’ and ‘to gain professional thinking and a broader view’, while as the disadvantages of RN-to-BSN programs were ‘geographical isolation of institutions’, ‘limitation of information’, and ‘underdeveloped school environments’ in this order. 3. The survey based on opinions toward self-directed learning showed that there was a need of detailed guidelines for self-directed learning. Most agreed that it was a very effective learning method for a RN student, and the self-directed learning method Increases motives for learning. 4. The students' anticipatory effect after graduation were ‘self-achievement’, ‘development of professional skills’, and ‘admission to post-graduate school or programs to study abroad’. 5. The students were very satisfied with the quality of faculty members, and satisfied with the quality of lectures and teaching. However, students were unsatisfied with rented lecture rooms, and very unsatisfied with self-directed learning methods. 6. School nurses showed higher statistical significances in the need for teaching material and anticipatory effect after graduation than other RN students working in hospitals and public health agencies. Also, school nurses, public health nurses, and industry nurses showed higher statistical significances in motives of admission than RN students working in hospitals. Further more, staff nurses, school nurses, and industry nurses showed higher levels of satisfaction toward a RN-to-BSN programs than nurses in higher positions, such as administrators or directors of nursing. 7 City residents were more satisfied with RN-to-BSN programs than rural residents. Otherwise, the rural residents had higher motives for admission, a bigger need for teaching materials, and recognition of the disadvantages of RN-to-BSN programs than city residents. Finally, RN students who earned below a monthly income of ￦1,000,000 showed higher motivation for admission than those who earned more than ￦1,000,000.

The open data portal collects data created by public institutions and opens and shares them according to related laws. With the activation of the Fourth Industrial Revolution, all sectors of our society are demanding high quality data, but the data required by the industry has not been greatly utilized due to the lack of quantity and quality. Numerous data collected in the real world can be implemented in cyber physical systems to simulate real-world problems, and alternatives to various social issues can be found. There is a limit to being provided. Location intelligence is a technology that enables existing data to be represented in space, enabling new value creation through convergence. In this study, to present location intelligence of open data, we surveyed the status of location information by data in open data portal. As a result, about 60% of the surveyed data had location information and the representative type was address. Appeared. Therefore, by suggesting location intelligence of open data based on address and how to use it, this study aimed to suggest a way that open data can play a role in creating future social data-based industry and policy establishment.

This paper is the second part of a research which aims to look into the regional development process and the quality of life of Youngnam area. and to suggest a prospect and tasks for the future development of the region. All cities and regions including Youngnam area seem to be involved in a rapidly changing process of conditions for development, because of a recent economic and political transformation in the national and global scale. It can be thus said that, taking such a process into consideration seriously, each city or region needs to establish a long-term prospect and goal, and to set up and practicize its development plan. From this point of view, this paper reconsiders the changing process of conditions for development of Youngnam region, and suggests an alternative development plan. At the first, the changing conditions of regional development are investigated in economic, political, social, cultural and environmental aspects. Secondly, some actual planning practices in this regions are examined and their problems are pointed out. Thirdly, an alternative model for regional development is suggested and development tasks in each aspects are discussed in relation to each other. Finally some regional development strategies are provided in the spatial as well as the sectoral dimision. As a results of this research, it is argued that the development of Youngnam region should pursue both an improvement of socio-cultural and ecological institutions for ensuring humane life of dwellers within the region, and a enforcement of economic and political self-sufficiency in an organic relation between regions and to the whole society. This kind of argument can be applied to every city or region. But it would more significant for Youngnam region, because this region, which once experienced a rapid economic growth but now is fallen into a serious economic stagnation, tends to contrive material plans to redevelop regional economy, while ignoring social plans to improve quality of life.

This study assessed the nutrient consumption of children from lunch at day care centers and kindergartens. A total of 184 lunch plates were selected in two child day care centers and two kindergartens in Seoul. Weights of the menus in planned meals were measured and amount of served and consumed lunches were calculated using a digital photography technique. Nutrients of the planned, served, and consumed lunches were assessed using CAN-Pro 4.0 and the Index of Nutritional Quality (INQ) was calculated for each meal. Compared with the estimated energy requirement for lunch for 3-5 year old children, the planned meals of the child day care centers and kindergartens contributed 42.8% and 98.8% of the daily energy requirements, respectively. At a child day care center, a served meal provided more nutrients than a planned meal since some children requested more servings after eating the served meals. This showed that the planned meal did not meet children's needs as well as the nutrient requirements. At the other child care center, children were served less than the planned meal by 6.8%, which resulted in serving less energy, calcium, potassium, and vitamin C than the required nutrients for lunch. Kindergarten A served meals with the energy requirement for lunch of 101.8%, but Kindergarten B served a meal with the energy requirement of 83.5%. Since the served portions were too small to meet nutrient requirements of the children, they consumed almost all the food served, and their nutrient consumption was similar to the nutrients served. Even though they consumed all the food served, their nutrient consumption did not meet their nutritional requirements. When assessed by INQ, the quality of the meal was good; children could consume enough nutrients when served proper quantity. Teachers who are responsible for serving meals need to be educated on proper portion sizes and how to encourage children to practice healthy eating. To promote healthy eating among children, parents need to provide children with messages consistent with what they have learned at institutions and to be a good role model in daily dietary life.
