우리나라 대부분의 대학들이 강의평가를 하는 첫째 목적은 수업개선이고, 둘째 목적은 교수업적평가의 기초 자료로 활용하기 위한 것이다. 많은 대학들이 참여율을 높이기 위해서 온라인을 이용한 강제적인 강의평가를 실시하고 있다. 그 결과 90% 이상인 높은 참여율은 얻었으나, 강의평가결과 중 51.4%는 10개 문항에 대하여 모두 같은 번호로 무성의하게 응답하는 결과를 초래하게 되었다. 이런 무성의한 자료를 제거하거나 보정하지도 않은 채, 모든 문항의 점수를 합한 절대 점수를 가지고 강좌를 서열화하고, 교수업적을 평가하고, 시간강사 재임용 여부 등에 기초 자료로 활용하고있다. 강의평가 자료를 통계분석하기 전에 학생들이 얼마나 성실하게 응답한 자료인지 먼저 확인해 보아야 한다. 대학 행정 당국은 양질의 강의평가 자료를 얻기 위하여 강제적인 현행 강의평가를 즉시 중지하고 전면적인 강의평가 제도 개선 방안을 강구해야 할 것이다.

In this paper, we evaluated educational effects of H-STEAM group play contents(a course) and tried to suggest a convergent model for college liberal art curriculum. We opened a mixed course(math, art, engineering, and humanities) with team teaching for this purpose. For the test, we collected data from survey, K-W-L sheet, and reflection paper from 23 students who enrolled in this course. Students should do a team project during the course, propose a new group game, and write K-W-L sheet at the end of each session and reflection paper at the final stage. As a result, it is said that H-STEAM group contents had an effect on students' satisfaction and achievement. During the course, students made academic efforts and were able to construct convergent knowledge from the four fields. From this study, we are sure that H-STEAM contents can play a substitute role for the traditional liberal arts program and innovate the curriculum for the knowledge convergence society.

Purpose: Colorectal cancer is becoming an increasing concern in the middle-aged population of Iran. This study aimed to compare the preliminary results of short-course and long-course neoadjuvant chemoradiotherapy treatment for rectal cancer patients. Materials and Methods: In this clinical trial we recruited patients with rectal adenocarcinoma located from 5 cm to 15 cm above the anal verge. Patients in group I (short-course) received three-dimensional conformational radiotherapy with a dose of 25 Gy/5 fractions in 1 week plus concurrent XELOX regimen (capecitabine 625 mg/㎡ from day 1-5 twice daily and oxaliplatin 50 mg/㎡ on day 1 once daily). Patients in group II (long-course) received a total dose of 50-50.4 Gy/25-28 fractions for 5 to 5.5 weeks plus capecitabine 825 mg/㎡ twice daily. Both groups underwent consolidation chemotherapy followed by delayed surgery at least 8 weeks after radiotherapy completion. The pathological response was assessed with tumor regression grade. Results: In this preliminary report on complications and pathological response, 66 patients were randomized into two study groups. Mean duration of radiotherapy in the group II (long-course) was 5 ± 1 days (range, 5 to 8 days) and 38 ± 6 days (range, 30 to 58 days). The median follow-up was 18 months. Pathological complete response was achieved in 32.3% and 23.1% of patients in the shortcourse and long-course groups, respectively (p = 0.558). Overall, acute grade 3 or higher treatment-related toxicities occurred in 24.2% and 22.2% of patients in group I and II, respectively (p = 0.551). No acute grade 4 or 5 adverse events were observed in either group except one grade 4 hematologic toxicity that was seen in group II. Within one month of surgery, no significant difference was seen regarding grade ≥3 postoperative complications (p = 0.333). Conclusion: For patients with rectal cancer located at least 5 cm above the anal verge, short-course radiotherapy with concurrent and consolidation chemotherapy and delayed surgery is not different in terms of acute toxicity, postoperative morbidity, complete resection, and pathological response compared to long-course chemoradiotherapy.

It has been often reported that a water-jet propelled high speed vessel lost the course keeping ability in seaway. In this study, model tests of a high speed vessel were performed to measure the running attitude and to check the course keeping ability. The model ship may lose the course keeping ability due to bad running attitudes such as bow drop. So model tests were carried out to improve the running attitude by changing the position of longitudinal center of gravity and using appendages at the bow and the stern of a model. The position of lateral center of pressure moved toward stern and the course keeping ability was improved by modifying the transom wedge angle.

Yaw-checking and course-keeping ability in IMO's ship manoeuvrability standards are reviewed from the viewpoint of safe navigation. Three kinds of virtual series-ships, which have different course instability, are taken as test models. The numerical simulation on Z-test is carried out in order to examine the correlation between known manoeuvrability in spiral characteristics and various kinds of overshoot angle. Then simulator experiments are executed with series-ships in a curved, narrow waterway by six operators(five active pilots and one ex-captain) in order to examine the correlation between known manoeuvrability and degree of manoeuvring difficulty. IMC criteria for yaw-checking and course-keeping ability are discussed and revised criteria are proposed.

The study investigated the effects of differences in some electronic course designs on university students' Computational Thinking Skills (CTS). Towards this end, the researcher adopted the experimental research design of a quasi-experimental of two experimental groups. The first group was taught an e-course designed in a sequential pattern, and the other group's course was designed according to the holistic model. A CTSs test was prepared to collect the relevant data, and the data were analyzed statistically using these tests- Pearson correlation Mann Whitney and Alpha Cronbach. Results revealed statistically-significant differences at the level α=0.05 between the mean scores of the first and second experimental groups in favor of the latter in the CTS test. The findings gave ground to put forward some salient recommendations, including the need to expand computational thinking in universities' educational process. It also recommends urging faculty members to enhance e-courses in the educational process and provide technical support to students and faculty members.

This paper is about a case study of an interdisciplinary and intercultural collaborative design project course that has been offered for six years. The distinct characteristics of this course lie in that its students consist of those in two different disciplines, mechanical engineering and industrial design, and also in two different countries, Korea and Germany. The themes of the design project have been selected differently over the years, but always were related to transportation and, particularly, personal mobility devices. The paper first delineates the course and illustrates examples of the outcomes. Then, unique aspects and challenges of the course that have been observed through the six runs and that are associated with the intercultural and interdisciplinary nature are indicated and discussed. The author is convinced that this course has been successful in helping prepare the students for globally-operating manufacturing companies in the future. It is hoped that the findings from this course and the discussions contained in this paper would help those who plan to offer similar courses.

This study tracked the changes of preservice biology teachers' pedagogical knowledge along with science teaching efficacy throughout sequentially developed science methods course I and II over two consecutive semesters. Two courses, science methods course I and II, aimed these preservice teachers to discuss the notion of science teaching with teaching and learning theories, to learn science instructional models, to design lessons utilizing science instructional models, and to eventually implement microteaching. The preservice teachers were mainly engaged in cooperative instructional planning activities through science methods course I, and engaged in cooperative microteaching activities through the science methods course II. This study revealed that preservice teachers successfully developed pedagogical knowledge and science teaching efficacy after two science methods courses. The science methods course I where cooperative instructional planning activities occurred helped the preservice teachers to improve pedagogical knowledge but not science teaching efficacy. Based on their pedagogical knowledge development, then, these preservice teachers increased science teaching efficacy belief after completion of the science methods course II.
