본 연구에서는 제조업 분야에서 보편적으로 활용되어 온 제약이론을 바탕으로 강교 제작공장의 생산성을 향상시키기 위한 자원할당 방법론을 제안한다. 이를 위해 도장 공정을 병목공정으로 정의한 후, 공정 전용 자원할당(OSRA), 제품 전용 자원할당(PSRA), 범용 자원할당(GRA) 등 3가지의 자원할당 방법론을 개발하였다. 강교 공급사슬 시뮬레이션 모델을 활용한 성능평가 실험 결과, GRA 방법론이 재공재고수(NWIP)와 대기시간(WT) 측면에서 가장 우수한 성능을 보였다. 특히, 강교 제작공장의 부하와 부하 변동성이 증가할수록 다른 두 전용 자원할당 방식과의 성능 격차는 더욱 커졌다. 평균적으로 GRA는 NWIP과 WT를 OSRA 대비 36.2%, 34.6%, PSRA 대비 71.0%, 70.4% 감소시켰다. 재공재고수와 대기시간의 감소는 병목현상의 완화를 의미하며, 이는 결국 강교 제작공장의 생산성이 향상되었음을 의미한다.

The purpose of this study is to present a practical class design model that applies the problem-based learning (PBL) method to the subject of home economics. To begin with, a specific class model example was developed by conducting thorough document research and expert consulting. Two modules, named "Click! Global Leisure Environment" and "Happy Leisure Product Launching" were presented as the PBL questions. The case study focused upon in this research is an elective course called "Leisure Culture and Life Management". The 21 students enrolled in this course were considered in this study. Two teaching methods, namely a face-to-face teaching method and a web-based system "Snowboard" teaching method, were used to run the class. The research results are as follows: first, theoretical research and program development and demonstration were practiced with five different age groups: childhood, adolescence, university student, middle age, and senescence. Then, selfevaluation, peer evaluation, and group evaluation were conducted to motivate the students. Finally, a class evaluation was conducted by questioning the lecturer, who ranked well, scoring higher than or equal to 4.0 points out of 5.0 on all the questions. Through the PBL method, students showed an improved study attitude with more proactive participation in the class, they strengthened their communication skills and created a synergy with their team members. This study has significant meaning because it is the first research to apply the PBL method to home economics. Therefore, we expect other curricula to apply PBL and fully utilize this teaching method as well in the future.

The response behavior of a fish school to an approaching vessel was observed using scanning sonar. The evaluation using six parameters, which signify characteristics of school shape and behavior by sonar image processing, was proposed. Ten fish schools were analyzed and among them, three fish schools were identified for their changing shape, swimming direction, and swimming speed. Moreover, by tracing fish schools on stack of sonar images, these fish schools were seen to exhibit an apparent change of school shape and behavior. Therefore, the evaluation method of fish school behavior using six characteristic parameters indicating fish school shape and behavior by sonar image processing is useful.
