The purpose of this paper based on the preliminary research is to dove)or the standard job models for children's service of public and children libraries in Korea. To do so, the author surveyed and analysed the perception of library staff of current jobs for children's service using the online questionnaire. And author proposed the standard models(importance difficulty, professionalism, and performance requirements) of library jobs for strengthening children's services. In addition, the this study suggested a plans to enhance professionalism of children's librarian and to introduce its qualification system.

The automatic forming sequence design system can determine desirable operation sequences even if they have little experience in the design of cold forging process. This system is proposed,which generates forming sequence plans for the multistage cold forging of zxisymmetrical solid products. Since the process of metal forming can be considered as a transformation of geometry, treatment of the geometry of the product is a key in planning processes. Forming sequence for the part can be determined by means of primitive geometries such as cylinder,cone, convex, and concave. By utilizing this geometrical characteristics(diameter,height, and radius),the product geometry is expressed by a list of the pnmitive geometries. Accordingly, the forming sequence design is formulated as the search problem which starts with a billet geometry and finishes with a given product one. Using the developed system, the sequence drawing with all dimensions, which includes the proper sequence of operations for the part, is generated under the environment of AutoCAD. The preliminary choice of some feasible forming sequences can verify by using the finite element simulation.

The Purpose of this study was to identify the sensibility elements and the evaluative dimensions of internet fashion shopping mall to supply optimal experience to the customer. First, association words for internet fashion shopping mall by open-ended method and sensibility-expression-adjective feeling as navigating personally 57 shopping mall dealing with fashion products were collected. Collected adjectives were ranked after making index by frequency and diversity. Then, correlation analysis was executed to extract independent adjective and their opposite words. Semantic differential scale was made for internet-fashion-shopping-mall-evaluation. After preliminary investigation with this scale, factor analysis was implemented. 12 sensibility evaluation words were extracted. Then, 200 subjects evaluated satisfaction degree for 8 selected shopping mall. To explain the hierarchy of internet fashion shopping mall, cluster analysis was applied. The understanding of sensibility element and evaluative dimensions of internet fashion shopping mall can be utilized efficiently as basic materials when marketer plans internet shopping mall design and makes marketing strategy.

This study is to present an engineering solution for the repair frequency and repair rates of a building. The existing data for the repair frequency and repair rates are used to draw the probability distribution for the generalized repair frequency and repair rate in a building. The suggested methodology can be widely used for most buildings to estimate the legal repair frequency and repair rates. Also, the methodology can be applied to resolve the risks on the maintenance costs in LC (Life Cycle) plans or LCC (Life Cycle Cost) analysis. As the future studies, there are the multiple regression analysis including the parameters on incurred costs and the decision methods on efficient repair and replacement.

This paper gives an account of teleoperated mobile robot system which is intended to operate in hostile environments where human access is limited or prohibited. A prototype mobile robot equipped with manipulator was designed and initial tests were made in laboratory environment. Test results, yet preliminary, have been encouraging for further research efforts. Future plans emerging from these initial results are also summarized.

Feasibility study has been accomplished to evaluate the effectiveness of the in-vessel core debris cooling through lower cavity flooding using two dimensional finite difference scheme. The volume of cerium pool and decay power rate generated in corium pool were evaluated as important parameters to the temperature distribution on the reactor vessel lower head through previous works. In this study, the corium volume based on the System 80＋ core structure and time dependent decay power rate are considered for feasibility evaluation. In addition, preliminary plans for the in-vessel core debris cooling through lower cavity flooding as severe accident management strategy, i.e. flooding timing, method and capacity, are suggested based on the result of the numerical study, international tendency related to in-vessel core debris cooling through lower cavity flooding.

In this study, through the development of the Survey questions for employments to increase employment rates which has 2 items in 23 questions and the analysis of the questionnaire based on the response results of 289 senior students who are finding their jobs. It has the effect that providing basic data about employment preparatory stance and giving counseling, discussions and future directions. So there are carefully proposed desirable increasement plans of employment rates by considering the regional characteristics and reality.

Recently, there has been growing interest in Gyongin Line demand estimation, because SMRT(Seoul Metropolitan Rapid Transit Corporation) Line 7 will be extended west by 9.8km from Onsu to meet the Gyongin Line at Bupyeong-gu Office. This study was designed to estimate the change of traffic demand in Gyongin Line before and after the completion year 2011, also provide against the economic loss caused by the derived demand from Gyongin Line to SMRT Line 7. In this paper we give preliminary results for the strategic plans for traffic demand estimation and train operating plan in Gyongin Line by analyzing transport performance of Seoul metropolitan subway, and an additional study on the transportation market and the urban development plan is needed for more accurate results.

This study aims to develop an educational program in using credit card for undergraduate students. In order to achieve this aim, a processor has been followed. first of all, a fundamental work to select the educational contents was Preceded with a survey of learners' needs, case studies of counselling at Consumer Protection Board, and preceding studies. After choice of educational contents, learners' demands on how to manage the educational program was executed in advance. Second, reflecting the above mentioned educational contents, a concrete educational program was built. Based on the constructed plans, both preliminary training and main training were proceeded. Third, to evaluate the effects of the educational program, the knowledge difference, behaviors and attitude changes were all diagnosed. The result suggested that the educational effect was significant in all evaluations section. At last, final program of using credit cards was completed.

Current plans for legacy nuclear wastes stored in underground tanks at the U.S. Department of Energy's Hanford Site in Washington are that they will be separated into high-level waste and low-activity waste fractions that will be vitrified separately. Formulating optimized glass compositions that maximize the waste loading in glass is critical for successful and economical treatment and immobilization of these nuclear wastes. Glass property-composition models have been developed and applied to formulate glass compositions for various objectives for the past several decades. Property models with associated uncertainties combined with composition and property constraints have been used to develop preliminary glass formulation algorithms designed for vitrification process control and waste-form qualification at the planned waste vitrification plant. This paper provides an overview of the current status of glass property-composition models, constraints applicable to Hanford waste vitrification, and glass formulation approaches that have been developed for vitrification of hazardous and highly radioactive wastes stored at the Hanford Site.
