The present study aims at identifying the nature of the organizational patterns for serial management and thus providing an assitance for decision-making in regards to how the serials in an individual library be processed. The premise of the paper is that effective management is ensued from adopting proper organizational arrangement. In the first part. attempts are made to bring to the fore the problems inherent in serial management and the efforts made for possible solutions. The main portion of the paper eximines the two outstanding patterns; namely, the decentralized arrangement patterned after the traditional functions of a library and the centralized one integrating such functions as acquisition, cataloging and information service. Both are examined in light of nature, development, applicability, strengths and weeknesses. Automation is viewed as a strong force for a change in organizing serial work as it has already brought about organizational change in some large libraries. The general conclusion is that a large collection(5,000 active titles or more) has much to benefit from a separate, specialized department. which integrates the related functions; and the smaller collection can be effectively treated like the rest of the library materials, assigning a specific unit responsible for serial work and promoting an informal communication activities which would bring about coordination and coorperation for the free flow of serial work.

In order to predict the dispersion of a thermal discharge with strong turbulent and buoyant effects, the development of a numerical model using turbulence model and its application are significantly increased. In this study, a 3-dimensional steady-state model for the surface discharge of heated water into quiescent water body is developed. For the model closure of turbulent terms the 4-equation turbulence model is used. For economic numerical simulation, the elliptic governing equations are transformed to the partially parabolic equations. In general, the simulated results by the present model agree well to the experimental results by Pande and Rajaratnam. The model characteristics are presented in comparison with the predicted results of the 2-equation turbulence model by McGuirk and Rodi. Applying the 4-equation turbulence model to the Korea nuclear unit 1 at Kori site, feasibility and efficiency of the present model are validated.

A novel supramolecular network containing binuclear copper unit $[Cu(phen)_{2}({\mu}-ID\;A)Cu(phen){\cdot}(NO_{3})](NO_{3}){\cdot}4(H_{2}O)$ (1) was synthesized through the self-assembly of iminodiacetic acid ($H_2IDA$) and 1,10-phenanthroline (phen) in the condition of pH = 6. It has been characterized by the infrared (IR) spectroscopy, elemental analysis, single crystal X-ray diffraction, and thermogravimetric analysis (TGA). 1 shows a 2-D supramolecular structure assembled through strong and unique $\pi-\pi$ packing interactions. Density functional theory (DFT) calculations show that theoretical optimized structures can well reproduce the experimental structure. The TGA and powder X-ray diffraction (PXRD) curves indicate that the complex 1 can maintain the structural integrity even at the loss of free water molecules. The magnetic property is also reported in this paper.

Electroluminescence(EL) devices based on organic thin films have attracted lots of interests in large-area light-emitting display. Recently, many EL researcher have interested a new emissive organic material. In this study, light-emitting organic electroluminescent devices were fabricated using Langmuir-Blodgett(LB) technique with new emissive organic material. This new emissive organic material were synthesis by our teams and we called PECCP [poly(3,6-N-2ethylhexyl carbazoly cyanoterephthalidene)] which has strong electron donor group and electron acceptor group in main chain repeat unit. This material has good solubility in common organic solvent such as chloroform. THF, etc. and has a good stability in air. In here, the new emissive material is applied to Langmuir-Blodgett(LB) method because our new material has a good stability in air. Optimum conditions of film deposition were examined by a surface pressure-area( $\pi$ -A) isotherms with various factors. The LB film were deposited on a indium Tin Oxide(ITO) glass. We were investigated by measuring current-voltage(I-V) characteristics. Also we were measured the UV/visible absorption at about 410nm and PL spectrum at about 530nm. We are attempt to the electroluminescence device properties of the new emissive material by Langmuir-Blodgett(LB) technique.

Fisheries resources living in inland have continuously reduced due to over-fishing and development thoughtless for the environment. Inland fisheries that target the fisheries resources have been also confronted by several problems such as insufficiency of inland fisheries management systems, inconsistent fisheries management system, inferior infrastructure of inland fisheries, and decreasing fishermen's real income. These problems have demotivated fishermen who want to focus on fishing and farming activation. Therefore, this paper provides alternatives of reorganization for turning to sound and healthy inland fisheries industries by reviewing Korean inland fisheries management systems. The reorganization should be preferentially granted resource management by water system considering geographical conditions, seed release, and establishment of fisheries order for maintenance of sound and healthy inland fisheries. Also, the reorganization should be moved toward the competitive strengthening of "company unit" for inland fisheries, the nourishment of fisher-oriented fisheries management system, strong relationship among inland fishermen, the systematic management of inland fisheries, the strengthening of guidance service for inland fisheries, the extension of infrastructure related to fisheries production, the development of inland fisheries policy including public people, and the improvement of inland fisheries system and law reflecting various users of inland fisheries.

Purpose. Nursing has evolved as a unique and independent field over the last decades. Unfortunately, many nurses in Korea express concern that they lack appropriate background knowledge in bioscience necessary to practice nursing competently. To determine the reasons of their concerns, we examined the perceptions of RNs regarding bioscience courses in their undergraduate (Baccalaureate and 3 year diploma program) and their perceived relations to the practice of nursing. Methods. The structured questionnaires were sent to 3 university-affiliated tertiary hospitals in Seoul, Korea. Results. The responses given by the nurses in the two groups were similar. The nurses in this study reported that the bioscience courses they took as undergraduates had little relation to their professional tasks. This lack of link between bioscientific knowledge and nursing practice may be partly due to the fact that the courses are taught by non-nursing faculties who are not familiar with nursing tices. It also appears that bioscience knowledge deficit was most prominent during nursing assessment regardless of the program they attended or the unit they are currently working. Conclusion. Bioscience courses should be integrated into the nursing curriculum properly and taught by nursing faculty who have a strong background in biological sciences.
