The purpose of this study was to examine how the relationship with grandparents and intergenerational integration program influences the children's attitudes toward elderly. Data for the study were collected from 132 elementary school students who attended the regional children's centers or social education centers that conduct intergenerational integration programs. The respondents reported positive attitudes toward elderly and perceived elderly as kind, likable, bright, clean and happy. A multiple regression analysis was conducted to identify the variables that affect children's attitudes toward elderly. While frequency of contact with grandparents, perceptions about grandparents, and frequency of intergenerational integration programs had strong effects on the children's attitudes toward elderly, experience of living with grandparents, perceptions about the intergenerational integration programs, and helpfulness of the intergenerational integration programs did not show significant effects on children's attitudes toward elderly.

This paper presents a new design method of the 1 generation wheel bearing unit using a numerical optimization technique in order to increase bearing fatigue life. For calculating the fatigue life, a method of load analysis is studied on the automotive wheel bearing system. The design variables selected are ball size, initial contact angle, number of balls, pitch diameter, pre-load, and distance between ball centers. The method of feasible directions in ADS (Automated Design Synthesis) is utilized to automatically find the optimum design variables. To validate the design method, a computer program is developed and applied to a practical passenger car model. The optimum design results demonstrated the effectiveness of the proposed design method showing that the system life of the optimally designed wheel bearing unit is enhanced in comparison with that of the initial ones within the given available design space.

This study was carried out to investigate the effect of changes in child care technology on mother-child contact by using all sorts of literature such as diaries, documents or statistical data. Child care technologies began to change during the 1960's. Diverse goods and services such as baby dry milk, paper diapers and child care centers have made child care easier and saved a great deal of time. This has also allowed women to participate in labor markets easily despite rearing children. But maternal contact with children have declined due to new goods and services and this trend is especially prevalent in early childhood. It could be supported that the convenience of rearing rather than the needs of children like as attachment to maternity primarily was considered in technological change. From this results it was suggested that we should develop the alternative child care technologies which better reflect children's needs.

A numerical model to obtain the temperature distribution in a radiation shield of cryogenic systems was proposed. Conformal mapping was used to transform the eccentric physical region of the upper plate to the concentric numerical region. The effects of the thickness of the radiation shield, the emissivities of the vacuum chamber and the radiation shield, and the eccentricity between the centers of the upper plate and the contact area with a cryocooler on the maximum temperature difference in a radiation shield were shown.

In this paper, we describe various efficient optimization algorithms for obtaining an optimal customer allocation in the telephone call center. The main advantages of the proposed algorithms are simple, fast and very attractive for massive dataset. The proposed algorithms also provide comparable performance with the other more sophisticated linear programming methods. The proposed optimal allocation algorithms increase the customer contact, response rate and management product and optimize the performance of call centers. Simulation results are given to demonstrate the effectiveness of our algorithms.

The disaster preparedness system in Korea has been developed in spite of many obstacles, but there are still many problems especially on actual preparedness including disaster drill and disaster medical system. Disaster drills performed by wide regional emergency medical centers for one years were analyzed based on the disaster drill report and additional compensation of incomplete data by direct contact with the participating institutions. On the disaster medical drills in Korea, it is necessary to emphasize drills on various types of disaster, active participation of medical personnels, drills combined with various types of related institutions, process of disaster medical aspect.

Knowledge, as a source of firm's competitive edges, has been drawing attention, while numerous enterprises are investing huge amount of assets to foster the right environments for executing knowledge management (KM). As a practical way of such KM, knowledge management systems (KMS) support the creation, diffusion, and utilization of knowledge, which are the tools for practicing such management style. Recently, the customer centers which make the closest contact with the customers are being concerned about the establishment of KMS. Considering the characteristics of real-time problem solving in customer centers during the consultation with the customers, the importance of KMS is paramount to the centers. This study analyzes major factors influencing the success and utilization of the customer center KMS's reestablishment, as an exploratory case study of the reestablishment of KMS in the customer center of K insurance company. First, the characteristic differences between the customer center's KMS and the traditional KMS are discussed, and the triangulation technique is applied to secure objectivity of this case study's findings. Major results of the case study state that, for the success of KMS and improvement of utilization, the followings should be considered preferentially: excellent system quality (accessibility, user convenience, easy searching, speed/menus); high information quality (accuracy, usefulness, timeliness, task-relevance, diversity, degree of specification); appropriate operation strategy and process for the utilization of system (education, training opportunity, appropriate personnel, speed and procedure of approval, compensation/evaluation); and change management via the support from the CEO's level (concern and participation of CEO, will to propel the project, investment, advertisement, etc.). This study provides practical suggestions with respect to factors which should be more carefully dealt with, since still many customer centers have hard time establishing and operating KMS due to lack of previous studies.

목적: 본 연구는 2개 대학 병원에서 폐결핵으로 진단 받고 치료 받았던 학동기 소아와 청소년들을 대상으로 임상 양상과 접촉 병력을 파악하고 접촉자 검진 실태에 대하여 알아보고자 하였다. 방법: 2008년부터 2012년까지 부산대학교어린이병원과 부산대학병원에서 활동 폐결핵으로 진단 받고 치료 받은 10-18세, 54명의 환자를 대상으로 하였다. 환자들의 의무기록을 통하여 진단 당시 임상 양상, 추정 감염 경로, 감염원과의 관계와 미생물학적 검사, 영상학적 검사, 접촉자 검진의 여부, 잠복결핵감염 치료 여부, 노출 후 결핵 발병까지의 기간 등을 후향적으로 조사하였다. 결과: 연령 중앙값은 16세였으며, 10-14세가 11명(20.4%), 15-18세가 43명(79.6%)이었다. 54명 중 35명(64.8%)은 전염성 결핵 환자와 접촉력이 없었고, 19명(35.2%)에서 접촉력이 있었다. 19명 중 가족 접촉자 군은 10명(52.6%)였고, 비가족 접촉자 군은 9명(47.4%)으로 학교 급우였다. 결핵 노출 후 접촉자 검진을 받은 환자는 가족 접촉자 군에서 10명 중 1명 이었고, 비가족 접촉자 군에서 9명 중 6명 이었다. 접촉자 검진을 받은 7명 중 3명이 활동 폐결핵, 1명이 잠복결핵감염, 3명은 결핵 감염의 소견은 없었다. 활동 결핵 환자와 노출 후 폐결핵으로 진단되기까지의 기간은 가족 접촉자 군에서 중간값이 2년, 비가족 접촉자 군에서 중간값 0.23년이었다. 결론: 학교 내 접촉자 검진과 같이 접촉자 검진이 적절하게 시행된다면 청소년 결핵을 조기에 발견하고 치료할 수 있게 되며, 이는 결핵의 확산 방지에 도움이 될 것이다.

2011년부터 중앙행정기관을 포함한 148개의 공공기관이 지방으로 이전하고 있다. 2012년 9월 14일에는 중앙행정기관 중에서 국무총리실이 첫 번째로 세종시 이전을 시작하였고, 연말까지 국무총리실을 포함한 6개 중앙행정기관과 6개 소속기관이 세종시 이전을 완료할 예정이다. 공공기관의 지방 이전과 관련하여 기록공동체 영역에서는 기록관 이전 문제를 고민해야 한다. 현재 대부분의 공공기관 기록관이 시설, 인력, 장비 등을 제대로 갖추고 있지 않은 현실을 감안할 때, 자칫 기록관 이전이라는 당면과제를 충분히 해결할 수 있을지 의문이다. 본고는 지방 이전 기록관의 현황분석을 통하여 이전 시 발생할 수 있는 대표적인 문제점을 파악하고자 하였다. 분석 대상 기록관은 이전을 완료하였거나 2012년에 세종시로 이전 예정인 중앙행정기관으로 하였고, 해당 기록관에 정보공개청구 및 개별접촉 방법을 통하여 필요한 자료를 확보하였다. 수집된 자료를 분석하여 기록관 이전에 따른 문제점을 확인하였고, 기록관 이전을 계기로 기존의 기록관 환경보다 개선된 사례가 있는지 확인하였다. 또한 기관 이전을 계기로 우리나라 기록관 체제의 현실적인 한계(전담인력 부족 및 미확보, 시설 공간 예산 부족 등)를 개선할 수 있는 방안을 제안하였다.
