As advanced information technology has been developing rapidly, libraries are moving from an ownership-centered information service toward information access service. Consequently, integrated automation systems of information centers that give not only cataloging information of their own collections but also various electronic information have appeared. In this study, a model of integrated automation system of an information center is suggested in terms of information types and cost, by taking case studies of some domestic and foreign libraries. Furthermore, the MIPOS Information & Resource Center System of POSCO Group is introduced as a good example of integrated automation systems in Korea.

The purpose of this study is to develop the algorithm applicable to the integrated production inventory model under quantity discount. To achieve this purpose, the integrated production inventory model which unifies the inventory problem of raw materials and the finished product for a single product manufacturing system is considered. The product is manufactured in batches and the raw materials are obtained from outside suppliers but some of the raw materials are discounted according to the purchasing quantity. The intergrated production inventory problem considered in this study is formulated by the non-linear mixed integer programming model, and the optimal solution is obtained by using the algorithm developed by Goyal. Then, the algorithm developed by this study is applied to the quantity discount problem, and the optimal solution is revised by this results. The quantity discount algorithm of the integrated production inventory model developed by this study gives a systematic procedure to obtain the optimum policy to minimize the total cost in any case. The numerical example involving 20 raw materials and 5 raw materials among them are discounted according to the purchasing quantity is given to verify the mathematical model and the algorithm developed in this study.

Christian records are greatly diversified as they are scattered in various institutions inside and outside of the church, which include records of Christian organizations, individuals, and the media. Given this, their management methods also vary. Because of this diversification of methods, it is difficult for people to access and make use of these records. This study aims to develop rules for the archival description of Christian historical records to provide a foundation that will allow users to have an integrated system where they can access all Christian records from different institutions including the church. For this purpose, the rules for archival description of the National Archives of Korea and the Korea Democracy Foundation, and those of the Presbyterian Church in the United States were compared, and from this comparison, features of each institution were identified. Using the features based on ISAD(G) (General International Standard Archival Description) and Christian historical records, the rules for the archival description of Christian historical records were developed.

Fine particles ($PM_{2.5}$) were collected and analyzed from December 2005 through December 2009 in Chuncheon, Korea to investigate the long-term trend of $PM_{2.5}$ concentrations. Also $PM_{10}$ concentrations were collected from Environmental Monitoring System operated by Ministry of Environment. Average concentrations of $PM_{2.5}$ and $PM_{10}$ were 30.5 and 58.2 ${\mu}g/m^3$, respectively. Both $PM_{2.5}$ and $PM_{10}$ were significantly affected by meteorological factors including wind speed, wind direction and precipitation. They generally decreased as wind speed increased (p=0.000), and increased when there was a prevailing westerly wind. Low concentrations of $PM_{2.5}$ were observed during rainy days while high concentrations were shown when fog, mist and/or haze occurred.

The Korean government has actively accepted private investments in building expressways to improve its financial status. As of 2012, 422km of 9 private expressways are under operation, and until 2016 additional 15 are planned to be built with private investments. However, on average, each private expressway is at most 37km long, which works against economies of scale in maintenance and thus leads to inefficiencies such as traffic jams, driver inconveniences, and the increase in operating costs. To resolve these problems, the present study suggested that the maintenance and tolling system should be unified across each private operator. Unifying the operation of private expressways was expected to reduce user travel times and tolls, and save operator maintenance costs. These economic effects were expected to be tantamount to hundreds of billions of dollars. The shared toll collecting system will also reduce user's delays by removing main line tollgates. This can save another hundreds of billions of dollars by ensuring driver's convenience and safety.

This study is to identify factors affecting public relations(PR) activities through newspapers among hospitals. 53 acute hospitals with more than fill beds were surveyed by telephone interview, and hospital-related articles on 4 major daily newspapers were searched in KINDS(Korea Intergrated Newspapers Database System). Hospitals' PR scores were evaluated by weighting the directoin and the number of hospitals mentioned in an articles. The scores were analysed as the outcome of PR activities by some general characteristics. The mean of PR score was 4.64, most hospitals(22, 41.5%) fell on the group scored more than 0 and less than 5. Hospitals with score under zero were 7(13.2%) and the hospitals scored over 20 point were 3(5.8%). The number of beds and area, two general characteristics of hospitals, had decisive effect on PR activities. Analysis showed hospitals over 1000 beds scored 17.06 point and this group accounted for the highest. Hospitals from 600 to 799 beds scored 2.86, with 800 to 999beds scored 1.93 and with 500 to 599 beds scored 0.59. Along with area, hospitals in Seoul scored 11.50 point, in Kyong-Ki and Incheon scored 1.50 and in the other areas scored -0.23 point. Department for PR and the number of workers in PR activities made hospitals active in PR. Hospitals with PR department scored 7.05 point, without PR department scored 0.98. Hospitals with workers who is whole responsibility over 5 scored 13.67, from 3 to 4 scored 6.54, from 1 to 2 scored 1.02, and the hospitals without workers who is whole responsibility scored 0.53. Among the characteristics related with PR activities, the assignment of a report in individual hospital had significant effect on the outcome of PR. Hospitals with assigned reporters scored 8.31 point, without them scored 1.89. Finally, the factors affecting PR score were identified by multiple regression analysis. The number of beds and the area(Seoul) were significantly associated with the score in positive direction.

Recently, it has become necessary to consider climate change when managing multi-purpose river functions. However, in terms of domestic rivers, the management of national and local rivers is separated and the river information cannot be integratedly handled. Especially, it is not sufficient to collect and update information by recycling reports for design and construction. In addition, the basic information of the rivers is dependent on the GIS-based RIMGIS system, but the reliability of the information is deteriorating due to the construction of spatial information using the river basement planning results. The purpose of this study is to investigate the current status of the information system with regard to the maintenance and operation of the river facilities. Through the verification of actual cases, the optimal solution was suggested from the point of view of practical information. As a result, we constructed an information system for the reliable maintenance of river facilities and examined the integrated information management plan. The results of this study can be used to improve the existing information and technical and institutional procedures for the integrated maintenance and operation of river facilities. It will be helpful to introduce the BIM as well as solve to the information gap with other fields through the establishment of an information framework to improve the information construction of river areas.
