The purpose of this study was to obtain a fundamental data for developing a policy concerning women and child rearing and a parent education program for young parents who are around their childbirth, a period crucially important both for the parents in terms of the role adjustment, career management, and family finance, and for the infants in terms of its physical and psychological well-being. The subjects were 509 mothers before and after childbirth currently living in the Metropolitan City of Daejeon. Data were obtained through questionnaires and interviews in two major areas of pregnancy-delivery-childcare and parent education. Data were analyzed using SAS, mostly through frequency analysis, percentiles, t-tests, and F-tests. Results of descriptive analyses were organized along the following areas and issues: Pregnancy(family planning, regular check-ups, difficulties, prenatal education, costs, etc.); delivery(type of delivery, delivery related experience, costs, clinic/medical institute of choice, worries/problems, help/supports, etc.); postpartum care(place, kinds of help and helper, costs, postpartum care facilities, etc.); childcare circumstances(place, carer, time schedules, childcare centers or facilities feeding and weaning, etc.); husband's attitudes and involvement in the overall process; working mothers(maternity leave, temporary retirement for child rearing, etc.); and, parent education(family planning, pregnancy, delivery, postpartum care, child rearing, areas or issues needing parent education, facilitative and hindering factors to ideal parenting, etc.). Differences between groups of pregnant mothers and postpartum mothers, working- and non-working mothers, groups of different income levels, mothers and fathers of different educational levels, mothers of first pregnancy(or childbirth) and experienced mothers were also analyzed. Several conclusions with suggestions were drawn in relation to the need for strong implementation as well as developing of policies on women and childcare and for developing a new parent education program for parents before and after childbirth.

토지이용실태에 관한 자료는 국토계획이나 지역계획을 수립하는데 있어서 필수적인 기초자료의 하나이다. 그러나 현재로서는 토지이용실태를 그대로 반영하고 있는 정확한 자룔르 구득하는 일이 그렇게 쉬운 일만은 아니다. 이러한 물리적 토지이용실태에 관한 자료들은 지리정보시스템기법과 원격탐사자료의 영상처리기법등을 적절히 잘 활용함으로써, 적은 비용으로도 신속하게 관련 정보를 추출할 수 있다. 이러한 동기에서 이 연구는 인공위서에서 감지한 수도권의 원격탐사자료(1979년 MSS자료와 1991년 TM자료)를 이용하여 첫째 착도권의 토지이용실태를 분석하고 둘째 지난 12년간 착도권내 도시지형의 확산모습과 토지용이변화과정을 그림과 통계로 정리함으로써 수도권 정책을 평가하는데 필요한 기초자료를 생산하며, 셋째 향후 국토계획이나 지역계획 수립시 인공위성 원격탐사자료를 적극 활용할 수 있는 연구토양과 분위기를 조성하는데 연구의 목적을두고 있다.

Purpose: The aim of this study was to evaluate the efficiency of community visiting health service units using DEA and to compare the results with those of traditional evaluation methods. Methods: Data were collected using 2008 annual reports of 10 districts in one city. Input variables were number of staff and operational budget per year and output variables were number of managed household per nurse, rate of controlled hypertension, and diabetes mellitus. EMS Window version 3.1 was used to measure efficiency score and bootstrapping Chi-square test was applied to identify differences between efficient and non-efficient unit by organizational factors. Results: The average efficiency score of 10 community visiting health services was about 66%. Only two of the units operated program efficiently. The career of the staff was one among other factors associated with efficiency. The evaluation results from the traditional method and DEA were totally different. Conclusion: These results indicate that, evaluation methods have very important and significant effects on the evaluation results of community visiting health service units. The DEA method is recommend as an alterative method for evaluating community visiting health service.

Present status of school lunch service and satisfaction on it were surveyed by questionnaires with 636 elementary school students in Inchon city. School lunch service was considered positive in 68.3% of the objectives. Most of the students thought the amount of rice and side dishes appropriate. And the ratios of students feeling the food taste fair and good were 36.6% and 56%, respectively. When dislike-foods were served, 58.3% still ate forcedly and 30.4% ate partly. Reasons for not eating up foods were dislike foods(46.7%), too much amount(20.3%), and bad taste(17.5%). Colors and appearance of foods were thought to be fair and good(93.8%). Warm foods were thought to be served warm as they should be(51.5%) and a little colder than they should be(43.5%). 65.4 percent of the students responded to be served cold foods cold enough as they should be. Dining hall was preferred as an eating place(61.4%). Half of the students occasionally washed their hands and 35.0% always did.

PSC 박스교에서 긴장재에 대한 조사는 체계적인 방법에 의해서 수행되어야 한다. 대표 긴장재 유형별로 위험 요인을 분석하고 장기적으로 위험도를 낮출 수 있도록 유지관리 계획이 수행되어야 할 예방적 유지관리 활동을 도출하는 것이 중요하다. 하지만 현 유지관리체계에서는 긴장재의 조사 및 보수보강을 위한 다양한 방법론이 연구되어 지고 있으나, 현실적으로 긴장재를 전수조사하는 것에는 어려움이 있다. 따라서 긴장재 선별에 대한 리스크 평가를 국내 PSC 박스교에 적용하기 위해 상태평가 및 유지관리체계에 맞춘 리스크 매트릭스 평가 지표를 제시하였다.

시시각각으로 변하는 시책 홍보 환경 속에서, 일선 공무원들이 무엇을 어떻게 해야 할지 몰라 홍보 업무에 어려움을 겪을 때가 많다. '홍보가 중요하다, 홍보가 문제이다.'라는 말을 가장 많이 하는 동시에 가장 많이 듣기도 하지만, 시민들이 시책을 인지하지 못한다면 그 시책은 무용지물이 될 수밖에 없다. 따라서 본 연구는 모바일 소통의 핵심인 소셜 미디어를 이용한 아산시의 시책 홍보 전략을 살펴보고자 한다. 특히, 모바일 소셜 미디어 서비스가 중요한 이유는 기존 소통 방식의 전환을 가져옴에 따라, 공공 차원에서도 서비스의 효율성 제고와 대국민 소통 강화에 적극 활용할 필요가 있기 때문이다. 시책 홍보를 이해하고 실행하는 데 있어서 원론적 매뉴얼이 아닌, 홍보 담당자들이 상황에 맞게 참고할 수 있는 시책 홍보의 실천적 가이드가 필요하다. 또한, 공공 기관의 소셜 미디어가 어떻게 운영되고 있는지를 살펴봄으로써 향후 공공 기관에서 시책 홍보 수단으로서 소셜 미디어를 활용하는 가이드라인을 제공해줄 수 있는 계기가 될 것이다. 아울러 긴급 정보 보호 사태를 맞이할 경우 소셜 미디어를 활용하면 보다 신속하게 정보를 알리고 효율적으로 대응할 수 있을 것으로 기대한다.

In this paper, experimental studies of the regrinding of tungsten carbide (WC-Co) tools for high-speed machining were conducted. Regrinding and a subsequent evaluation test were carried out for a flat endmill tool with diameters of 10 mm and 3 mm using a CNC five-axis tool grinder and a CNC three-axis machining center. Tool wear on the two types of endmill tools increased as the cutting length increased, and the tool wear was not influenced by the regrinding state. In case of the micro endmill with a tool diameter of 3 mm, the effective regrinding time was determined for a flank wear threshold of 0.3 mm considering the tool life according to cutting length. The tool lives of the 10 mm and 3 mm endmill tools were increased by 80% and 72%, respectively. This conclusion proves the Feasibility of the recycling of tungsten carbide materials in the high-speed machining of high-hardened materials for industrial applications.

This study is mentioning about basic information and guide related block types, through a comparison and an analysis of floor types which is shown as function in block types and public interior spaces. For the range of this survey, it is defind in the beginning of 1970' s to the end of 1990' s which was rapidly developed in hotel industry and also is chosen by 12 places in the first class hotels. On the purpose of this study is written by designing the basic information of architectures, new hotels which are built and managed in urban, refer to the survey and analysis of the characteristic in hotel. The following is conclusion by based on pre-survey of the analysis of a plan and a site in these hotels. First, as a result of analysis in block type, there are equally distributed in three types (in-type, combination type, close-type), except a atrium type exception, in 12 hotels(100%). Second, as a result of analysis of function type in public interior space, Con-course type is consist of 7(58%), Hall type is 5(42%) in the type of room in public interior space, in 12 hotels(100%). Third, the type in lobby on space plan are equally shown by the type of lobby in center(4PL.), of lounge in center(4PL.), and a compromising type(4PL.).
