This study was to investigate the concept of ISNI and to find its availability in authority control, realizing importance of ISNI as the bridge identifier including all the information media content industries. ISNI is needed for global and comprehensive name authority control as the bridge identifier for the identification of public identities of parties involved throughout the information media content industries in the creation, production, management and content distribution chains. First of all, it was to inquire ISNI concept, goal, terms and definitions, structure and syntax, allocation of ISNI, administration of the ISNI system, and metadata. Next, it was to suggest the applicability of ISNI in authority control. First, it should be needed to consider in applying ISNI for cooperative authority control. It is possible to interactively use the authority data created in library and other information industries area by constructing KISNI system. Second, it is possible to construct linked data by linking various identifier through ISNI identifier as bridge identifier. Third, it is needed to develop KORMARC for describing ISNI identifier in KORMARC bibliographic and authority record.

For preliminary structural analysis of superstructures on very large floating structures(VLFS), superstructures are analyzed considering elastic deformations of barge type lower-structures subjected to wave loads. In this case, to consider the effect of wave loads on the superstructure, initial displacements at the support points of superstructures are evaluated as input data for the analysis. However, the evaluation and application of displacement loads are tedious and very time-consuming processes. Therefore, this paper proposes a simplified static analysis method to analyze the structural behaviors of superstructures on very large floating structures subjected to wave loads. In this study, the member forces due to the variation of beam span and the amplitude and period of wave load are analyzed by using an example 4 span -3 story structure and the amplification factors for beam moments are represented by the specific regression equation.

The fundamental issue of information retrieval in the Internet-based society is closely interrelated with the characteristics of language selected. The McCune-Reischauer Romanization system is not only considered as the international standard for romanizing Korean language, it is also familiar to the majority of the Korean material users internationally. McCune-Reischauer system is adopted by the ISO, UNGEGN, ALA, LC, British PCGN, BL, and the relevant agencies in Europe, Canada and Australia etc. Encouraging for switching to the new Romanization system(2000) would result in complications among the library's catalogs and online databases, causing confusion for both staffs and readers. This paper analysed that the international efforts and rules for Romanizing Korean language materials and recommended direction for bibliographical issues.

The purpose of this study is to analyze cooperative relationship and information needs using the interlibrary loan (ILL) service data of the academic libraries. This study interprets the ILL service data as information source that including unsolved information problems. Also, this study normalizes the ILL service data using the collaboration index. The results of this study have three aspects. First, col hs-index can be useful tool for analyzing ILL service relationship between different sizes of libraries. Second, this study find out the information needs and the collection characteristics of each library after analyzing ILL data by subjects. Third, by applying col hs-index, we could analysis more objective ILL data and found out possibility of bibliographic index.

A plane field and a sloped field located at low-land plane and alpine areas, respectively, were monitored with respect to runoff, water quality and fertilizer uses from March to December, 2008. Runoff volume and Non-Point Source (NPS) loads were estimated and analyzed with respect to fertilizer uses. Total TN and TP loads from the sloped field were higher than those from plane field because of larger chemical uses in the alpine field than in the plane field. Organic matter load from plane field was higher than that from sloped field because more organic compost was applied to plane field than to sloped field. Event Mean Concentration (EMC) of measured water quality indices were relatively higher in both fields. Organic matter load per 1 mm rainfall were higher in plane field and TN and TP loads per 1 mm rainfall were higher in sloped field than those in respective comparing field. It was concluded that the type and application method of fertilizer could play an important role in the estimation of NPS pollution loads and the development of Best Management Practices (BMPs). However, it was recommended that long-term monitoring is necessary to better describe the relationship between fertilizer uses and water quality from agricultural fields because numerous natural and management factors other than fertilizer also affect runoff quality.

A silica mine monitoring was conducted from March to December in 2008 to measure rainfall, runoff amounts and pollution loads. A total of 13 rainfall-runoff events were measured and analyzed with respect to runoff ratio, pollutant concentration and load, and initial flush. Over rainfall-runoff events, 95% confidence range of SS concentration was 942.5~2,056.2 mg/L. Other measured water quality indices also showed relatively large variation. This wide concentration variation was thought to be caused by the bare working ground of the mine that was used to store, process and transport the mined silica. Total pollution load of the 13 rainfall-runoff events was SS 17,901 kg/ha, $COD_{Cr}$ 160.9 kg/ha, $COD_{Mn}$ 111.24 kg/ha, BOD 79.6 kg/ha, T-N 13.8 kg/ha, T-P 3.5 kg/ha, and TOC 39.3 kg/ha. Initial flush was not well observed except SS. Very high SS concentration and load was occurred when rainfall was large. Therefore, it was recommended to manage the bare ground not to discharge excessive pollutants during wet days by covering the ground or constructing runoff treatment systems such as a sediment basin.

Using artificial rainfall simulator, the soil loss, which is deemed as the most cause of muddy water problem among Non-point source (NPS) pollutant, was studied by the analysis of direct runoff, groundwater discharge, and soil water storage properties concerned with rainfall intensity, slope of area, and land cover. The direct runoff showed increasing tendency in both straw covered and bared soil as slope increases from 5% to 20%. The direct runoff volume from straw covered surface were much lower than bared surface. The infiltration capacity of straw covered surface increased, because the surface sealing by fine material of soil surface didn't occur due to the straw covering. Under the same rainfall intensity and slope condition, 2.4~8.2 times of sediment yield were occurred from bared surface more than straw covered surface. The volume of infiltration increased due to straw cover and the direct runoff flow decreased with decrease of tractive force in surface. To understand the relationship of the rate of direct runoff, groundwater discharge, and soil water storage by the rainfall intensity, slope, and land cover, the statistical test was performed. It shows good relationship between most of factors, except between the rate of groundwater storage and rainfall intensity.

This study aimed to develop a method to optimize residual chlorine concentrations in the process of providing water supply. To this end, this study developed a model capable of optimizing the chlorine input into the clearwell in the purification plant and the optimal installation location of rechlorination facilities, and chlorine input. This study applied genetic algorithms finding the optimal point with appropriate residual chlorine concentrations and deriving a cost-optimal solution. The developed model was applied to SN purification plant supply area. As a result, it was possible to meet the target residual chlorine concentration with the minimum cost. Also, the optimal operation method in target area according to the water temperature and volume of supply was suggested. On the basis of the results, this study derived the most economical operational method of coping with water pollution in the process of providing water supply and satisfying the service level required by consumers in the aspects of cost effectiveness. It is considered possible to appropriately respond to increasing service level required by consumers in the future and to use the study results to establish an operational management plan in a short-term perspective.
