Today’s ever-increasingly competitive shipbuilding market makes it essential for a shipbuilding company to have more efficient production processes and higher productivity as well as better design ability to obtain its competitiveness. A well-established production execution schedule plays an indispensable role to achieve this goal. Most shipbuilding companies carry out an evaluation on their mid-term plan once it is established. However, no evaluation activity exists for a production execution schedule, because practically all the companies depend on the field workers for the production execution scheduling. In this study, a prototype of a ship production execution schedule evaluation system is developed based on the component based design (CBD) methodology. This system enables one to make a production execution schedule that reflects upto- date shipyard situation and to validate whether the schedule is feasible or not by running a production simulation according to the schedule. Users can also make use of the system as a decision supporting tool that compares several different execution schedules and evaluates which one is the best execution schedule.

제조업에서는 최근 고객의 요구사항 변화로 인해 생산계획에 필요한 데이터 및 제약상황에 대한 정보가 매우 복잡하며 유연한 생산계획을 수립하는 것이 매우 중요해졌다. 신속한 생산계획을 수립해야 하는 상황에서 제조관리자는 복잡한 조건을 모두 고려하여 수립하여야 한다. 이러한 기능을 수행하는 생산계획 시스템을 구축하고자 한다면 복잡한 관련 데이터 및 프로세스에 대한 체계적인 분석은 반드시 필요하며 그렇지 않는다면 시스템을 구축하는데 시간과 비용의 낭비가 초래될 것이다. 본 논문에서는 데 프로세스 분석, 개체선정, 개념 데이터 모델 설계, 논리 데이터 모델 설계, 자료흐름도 작성으로 이루어지는 데이터 모델 설계 절차에 따라 사출성형 생산계획을 위해 필요한 논리 데이터 모델링을 수행하고, 이를 바탕으로 생산계획시스템과 생산계획 검증시스템 데이터 구성을 도출해 보았다. 이를 통해 생산계획 시스템 및 검증시스템을 구축한다면 데이터의 정확성을 높이고, 시스템 구축에 소요되는 시간적 측면에서 도움이 될 뿐만 아니라 데이터 설계도를 구축해 둠으로써 향후 유지 보수 측면에서 큰 도움이 될 수 있을 것으로 판단된다.

This analysis attempts to improve pedagogical approach toward general physical education by means of statistic analysis of the questionaire by 800 students (male 500, female 300) of Chungnam National University on their interests in it; what they most want to be taught, what they are not concerned about, suggestions on instructor's teaching of techniques and on teaching aids, class-hours, class-size, 400m track-running at the beginning of each class, and what their favorite sports are.

In order to collect basic data concerning with the frequencies and the patterns of substance use among Korean juvenile delinquents (for the proper guidance of substance using juvenile delinquents), questionaries were given to 757 Korean juvenile delinquents, from randomly selected 4 houses among 11 juvenile institutions using census method. Their age range was between 12 and 21. The actual number of cases put into the analyses was 571 including 521 boys and 50 girls. These collected data were computerized, using SPSS program and statistically analysed by chisquare method. The results of the study were as follows. 1. Among 521 juvenile delinquents, 253 cases (male 226 cases, Female 27 cases) had experienced substance use and one of every five of the subjects was shown to use substances habitually. 2. The frequencies of substance use did not significantly correlate with age groups, criminal records, types and objects of delinquency respectively. 3. The mean age of initial substance use was 15.67±2.09 years and 62.0% of 253 substance users appeared to have initially experienced. it between 15 and 17 years. 4. Most commonly used substance was psychostmulants, but inhalants were also used by growing numbers of the subjects. 5. The female, middle age group of juvenile delinquents had easier access to the substances than the male, earlier age group. 6. Male juvenile delinquents tended to use single substance, while the female tended to use multiple substances. 7. The motivation of substance use was peace-seeking (52.2%), adventure-seeking (30.6%), power-seeking (9.1%), friendship-seeking (5.5%), sex companion seeking (1.6%), and transcendence-seeking (0.4%). With increasing age, they tended to seek more peace or adventure and less power or friendship. 8. After the intake of the substances, male subjects tended to have experiences pleasure, while females displeasure.
