The library of elementary schools, which plays a role in the basic education to grow a responsible social member in an information society and to develop ability for collection, selection, summary, and utilization of various information, could be considered as new educational center. It should be changed to the establishment of informational education for preparing the information society in 21st century through the functional extension of the conventional library as reading and bookstand. Furthermore, it is necessary of trials that converts to the support system for interchange between establishment and student, for preparing educational system of teaching or studying, and for opening establishment to local communities in the future.

A content analysis revealed how marriage affected their clothing choices, types of communication conveyed with their spouses about clothes and shopping patterns. The primary result indicated that individuals take their spouses' clothing preferences into consideration. Couples exhibited varying frequencies of communication about clothing choices and developed a variety of shopping patterns. As a result of the findings from this study, future research directions are suggested.

In electic railway, 25kV is applied to AC sections of overhead contact lines and pantographs of Korea Train eXpress(KTX) make contact at speeds of 300km/h. Thus, there is a need to utilize wireless, optic, contact-less sensors to implement condition monitoring systems. This paper is based on describing and analyzing the condition monitoring system implementation technologies for efficient catenary current ratio characteristic assessment. The conclusion of this paper should be widely applied to design, diagnosis, completion of construction, current collection status, fault diagnosis, and selection of contact wires and suspension wires.

Purpose - The aim of this study is to evaluate the effectiveness of a corporate training program. The case study of HCL Technologies was used to investigate how training programs improve the performance of employees on the job, as well as to identify unnecessary aspects of the training for the purpose of eliminating these from future training programs. Research design, data, and methodology - An exploratory research design was used to conduct the study. The research sample size included 50 HCL employees. The sampling technique for the data collection was convenience sampling. Results - Training is a crucial process in an organization and thus needs to be well designed. Specifically, the training programs should provide adequate knowledge to all employees, ensure correct methods are used for the selection of trainees, and avoid any perception of biasness. Conclusions - Employees were not fully satisfied by the separation of the training program into two parts, on the job and off the job training, but if sufficient data is provided to employees in advance, this could help them during the training process.

This research was designed to find decision factors through color assortment planning process by Korean women's clothing merchandisers and to look for if there exists difference with American women's clothing merchandisers. A merchandise assortment is a collection of various quantities of styles, colors, sizes, and prices of related merchandise, usually grouped under one classification within a department. The subjects were 20 women's clothing merchandisers who work for clothing retail stores from 5 to 22 years in US and Korea. The authoring process was done for qualitative data analysis. The decision factors of color assortment planning were identified with four stages; information search, qualitative evaluation, quantitative evaluation, and selection. There were differences of color assortment decision factors due to different business types, business sizes, fashion-ability, sourcing ways, and merchandise turnover. Noticeable color assortment decision factor differences caused by country difference were not found except considering the target market ethnicity and skin color in US market. Korea merchandisers seem to be more sensitive to present sales data usages and spot order availability in color assortments because of more local production use than American merchandisers.

본 논문은 통합 검색에서 이질의 정보원으로부터 정보를 검색할 때 주어진 질의에 대해 가장 적합한 정보원 선택에 대한 새로운 알고리즘을 제안한다. 제안된 알고리즘은 질의어와 검색에 참여한 정보원간의 관련성 분포 정보를 사용하였다. 이때 관련성 분포 정보는 질의어와 정보원 사이의 관련성 정도를 말하며, 이에 대한 평가는 질의에 대해 정보원으로부터 임의의 크기 N 만큼 검색 문서를 수집한 후에 이들을 평가하여 추정하였다. 본 논문에서 제안한 관련성 분포 정보는 검색 문서의 재평가 값, 관련 문서의 순서 정보, 정확도 등으로 평가한다. 또한 제안된 알고리즘은 정보원 평가에서 검색 인덱스 정보가 필요 없으며, tf, df, N등의 메타 데이터로만 평가할 수 있는 장점이 있어, 동적인 환경에 적용하기가 매우 쉽다.

One of the objectives of any task design is to provide a safe and helpful workplace for the employees. The safety and health module may include means for confronting the design with safety and health regulations and standards as well as tools for obstacles and collisions detection (such as error models and simulators), Virtual Reality is a leading edge technology which has only very recently become available on platforms and at prices accessible to the majority of simulation engineers. The design of an automated manufacturing system is a complicated, multidisciplinary task that requires involvement of several specialists. In this paper, a design procedure that facilitates the safety and ergonomic considerations of an automated manufacturing system are described. The procedure consists of the following major steps. Data collection and analysis of the data, creation of a three-dimensional simulation model of the work environment, simulation for safety analysis and risk assessment, development of safety solutions, selection of the preferred solutions, implementation of the selected solutions, reporting, and training. When improving the safety of an existing system the three-dimensional simulation model helps the designer to perceive the work from operators point of view objectively and safely without the exposure to hazards of the actual system.

Various types of oil response equipments and oil recovery vessels are being developed in Korea from the 1990s to respond nil spill accidents. It should be considered prior to the selection of the oil skimmers to make the oil recovery system more efficient at early stage of oil spill accidents. Rotating baldes of vortex skimmer beneath the water surface concentrate oil and draw it into the weir, where it flows to a collection sump. In this study a recently developed Vortex-Disc skimmer(model : VDS-50) is introduced and the performance test results for the skimmer are discussed.

The aim of this study is to collect driver's psychophysiological signal under various road condition and to select and quantify psychophysiological variables for diagnosis of road-driver compatibility. A 4x4 vehicle with measuring devices was developed to collect driver's psychophysiological signal and collected driver's psychophysiological signal under various road conditions. The collected data were analyzed by the temporal pattern of signal overtime. Thirteen bio-signals with consistent pattern were selected and quantified in terms of slope and amplitude of the signal. These quantified values could be used as a part of tool to diagnose the road-driver compatibility.
