본고는 코로나19 사태로 인해 갑작스럽게 시행한 2020년 1학기 한시 전공 온라인 수업 방식을 되돌아보고 개선방안을 모색하였다. 필자는 온라인 원격수업은 대면 수업과 달리 학생들의 반응을 현장감 있게 확인할 수 없고, 학생들과의 의사소통에 제한이 있으며, 각종 프로그램의 활용을 위한 노력이 필요하다는 점을 체감했다. 그 과정에서 무엇보다도 온라인 원격수업에서 학생들을 집중시키는 방법이 중요함을 느꼈다. 이에 본 연구를 통해 온라인 원격수업에서도 학생들의 능동적이고 자기주도적인 학습 참여, 교수자와 학생들 간의 원활하고 활발한 의사소통, 주의력과 흥미를 높이는 학습 콘텐츠 활용 등이 학습능률을 높이는 수업의 핵심요소임을 확인할 수 있었다. 특히 한시는 음악적 요소(운율)와 회화적 요소(심상)가 돋보이는 문학 장르라는 점에서 다양한 디지털 자료들을 적극적으로 활용한 수업 방법은 학습효과를 높여주었다. 이를 통해 학생들이 한시 를 흥미롭게 느끼고 그 정서적 요소(분위기)까지 공감하게 되면, 의미적 요소(주제, 생각, 사상 등)에 대해서도 이해력이 깊어짐을 실감할 수 있었다. 또한 온라인 원격수업에서도 학생들이 작품을 직접 번역해 보고, 적극적으로 느낌과 감상을 얘기해 보고, 그것이 나의 삶과 오늘날 세상에 어떤 의미가 있는지 생각해 보고, 이러한 학습활동을 학생 간에 나눌 수 있도록 교수자가 도와주는 것이 중요하다는 점을 알 수 있었다. 따라서 이와 같은 점들을 고려하여 온라인 원격수업을 한시 교육 방법의 창의적인 전환의 계기로 삼는다면, 한시의 풍부한 예술성과 다양한 문학 콘텐츠들이 오늘날 대학생들에게 더 가까이 다가갈 수 있으리라 기대한다.

The improvement of resistance performance for the 4.99 ton class fishing boats was shown. The 4.99 ton fishing boats are the most commonly used one in the Korean coastal region. The evaluation of resistance performance was estimated by the Computational Fluid Dynamics (CFD) analysis. The CFD simulation was performed by the validation for various types of bow shapes on the hull. The optimized hull form from the simulation was selected and showed the best resistance performance. This hull type was tested on the towing tank in the National Institute of Fisheries Science (NIFS). The effective horsepower (EHP) was estimated by the resistance test on the towing tank with the bare hull condition. The drag force on the three service speed conditions was obtained for the resistance analysis to power prediction. The measured drag forces are compared with the results from the CFD simulation with one another. As results of the model tests, it was confirmed that the shape of the bow is an important factor in the resistance performance. The effective horsepower decreased about 30% in comparison with the conventional hull form. Also, the resistance performance improved the reduction of required horsepower, which especially contributed to the energy-saving for the fisheries industry. In the CFD analysis, the resistance performance improved slightly. In this case, the ratio of the residual resistance (CR) in the total resistance (CT) was high. Therefore, the CFD analysis was not enough to satisfy with reflection for the free surface and wave form in the CFD procedure. Both model test and CFD calculation in this study can be applied to the initial design process for the coastal fishing vessel.

This study investigated the effect of cooking class on improvement of eating behaviors and satisfaction with cooking activities in children. The questionnaires developed for this study were distributed to 380 mothers during June to August, 2011. A total of 286 questionnaires were used for analysis (81.7%), and frequency analysis, ANOVA, and χ2-test were completed using SPSS (version 14.0) software. The children with cooking experience (52.7%) showed more improvement of eating habits than children with no cooking experience (36.4%). Both types of children showed an ‘unbalanced diet’ with respect to eating habits. The overall satisfaction level was an average of 3.84±0.62. The effects after cooking activities varied for different aspects of improvement of eating habits: ‘Correcting unbalanced diet’ was 4.26±0.66, ‘nutrition knowledge’ was 4.06±0.70, ‘dining etiquette’ was 4.09±0.63, and ‘regular meals’ was 4.15±0.73. There was a significant difference between genders with regards to correcting unbalanced diet with vegetables (p<0.01). Ages from 10 to 12 were able to improve unbalanced diet with ‘grains’ (p<0.001), while ‘Kimchi’ (p<0.05) and ‘paste’ for ages from 10 to 12. In conclusion, cooking activities are regarded as effective in correcting unbalanced diet and eliciting positive changes in eating behavior.

A series of model tests carried out at the CWC of WJFEL for the purpose of prediction of resistance for the performance and improvement of resistance by attaching appendage for the ship of 50 knots class planing hull. The resistance performance evaluation has been carried out for the bare hull and for the appendage hull with two different depth of vertical type wedges. In the bare model test, trim and sinkage is calculated for the planing hull and the resistance is calculated. For minimizing the resistance, wedge appendage is attached and tested. Analysis and tests shows that for a 12.5mm wedge, resistance is minimum and overall power tallied to 5636ps.

This study was carried out at the CWC of Chosun university for the purpose of resistance performance improvement of planing hull, and the results of the tests were confirmed cooperatively with WJFEL. G/T 100 ton class planing hull form was selected, and the improvement of hull form including appendages were performed by using some model test techniques. The model test scope comprises resistance relative tests including wave profile observation, trim and sinkage measurement and flow visualization tests at full load and trial conditions for one bare hull and for two appended hulls. The final wedge and spray strip combined with improved hull form showed about 1.0 knot speed improvement at both of full and trial conditions, and outstanding improvement for fore wave phenomena.

이 연구는 어느 교사의 학교 차원의 수업개선 경험을 통해 교육개혁에 대한 시사점을 찾아보는데 목적을 두고 있다. 먼저 수업개선에 관심을 가지게 된 개인적 배경을 살펴본 다. 다음으로 개인적인 차원에서 수업개선을 위해 노력해 온 과정을 살펴본다. 그런 다 음 학교 차원의 수업개선을 해오는 과정에서 경험한 답답함과 딜레마, 그리고 자신에 대 한 반성과 변화된 점을 나눈다. 나아가 이 연구는 교사들의 참여와 협력을 교육개혁 성 공의 전제조건으로 본다. 이를 위해 교사들에게 ‘가르치는 자의 마음’을 불러일으킬 수 있는 시간을 마련해주고 학교를 수업중심으로 운영할 것을 제안한다.
