          해부실습에서 동료평가에 대한 의과대학생들의 인식과 필요성

          조정준,강성우,이승준,정수정,이재호 대한체질인류학회 2019 대한체질인류학회지 Vol.32 No.3

          Peer review in dissection is a good evaluation method that allows students not only to recognize professional behavior of peers, but also to look back on themselves. The purpose of this study is to analyze the recognition and feelings of students about peer review in dissection and to use peer review more effectively. In this study, it was to examine the reflection on grades of peer review, the improvement on attitude of dissection by peer review, and the reliability of peer review, also, additionally necessary subjects, the method of peer review, the emotions of students during the peer review. As a result of the questionnaire survey, the necessity about reflection of peer review (48, 67.6%), the improvement on attitude of dissection (41, 57.7%) and the reliability of peer review (30, 44.1%) were positive. Moreover, many students asked additionally necessary subjects not to be required except for anatomy (42, 67.7%). In the questionnaire on the method of peer review, to select students who have been good and bad in the practice is best (34 students, 57.6%). In the questionnaire for emotions of students during the peer review, “bad” was the most common (25, 39.7%), and the average value was about 2.7 in the 5 scale. There is a limitation to utilize peer review as an evaluation method of anatomy education. Therefore, much more effort is needed to improve the utilization of peer review and the professor should support the emotions of students during the peer review. 해부실습에서 동료평가는 학생들이 자신과 동료들의 행동을 되돌아보게 하는 좋은 평가 방법이다. 본 연구의 목적은 해부실습에서 동료평가에 대한 학생들의 인식과 감정을 분석함으로써 향후 동료평가를 보다 효 과적으로 사용하고자 한다. 본 연구에서는 2018학년도 K대학교 의과대학에 재학 중인 본과 1학년 학생 72명 을 대상으로 동료평가의 성적 반영, 실습 태도의 개선 효과, 평가 신뢰도와 동료평가 시행이 추가적으로 필요 한 과목, 동료평가 방법, 동료평가 시 학생들의 감정에 대한 총 6개 문항을 설문하였다. 설문 조사 결과, 동료평 가의 성적 반영의 필요성 (48명, 67.6%), 실습 태도의 개선 효과 (41명, 57.7%)와 평가의 신뢰도 (30명, 44.1%) 는 긍정적인 반응을 보였다. 그리고 해부학 외 동료평가가 필요한 과목은 없다 (42명, 67.7%)는 의견이 많았다. 평가방법에 대한 설문에서는 해부실습에 성실히 참여한 학생과 성실히 참여하지 않은 학생 모두를 평가하자 는 의견이 가장 많았다 (34명, 57.6%). 그리고 평가 시 감정에 대한 설문에서는 나쁨 (25명, 39.7%)이 가장 많았 으며, 평균값은 5점 척도에서 약 2.7로써 나쁨과 보통 사이였다. 아직 해부학 교육의 평가 방법으로 동료평가를 활용하는 데에는 많은 한계가 있기 때문에 동료평가의 활용도를 높이기 위해서는 평가 시 학생들의 감정을 잘 조절할 수 있도록 많은 노력이 필요하다.

          선반용 고속주축계의 동특성 해석

          조정준,김석일,최대봉 한국정밀공학회 1994 한국정밀공학회지 Vol. No.

          고속절삭을 통해서 가공능률과 가공정밀도의 향상을 도모할 수 있기 때문에, 최근에는 공작기계용 고속주축계가 많은 주목을 받고 있다. 본 연구에서는 주축 선단부에 무거운 척과 공작물이 위치하는 선반용 고속주축계의 동특성을 해석하기 위해서 유한요소법을 도입하였다. 특히 세장비가 비교적 작은 주축은 Timoshenko 이론으로, 폭이 유한한 베어링은 반경방향 외에도 모멘트방향의 강성 및 감쇠특성을 가지고 있는 것으로 모델화하였다. 그리고 선반용 고속주축계의 고유진동수와 감쇠비에 대한 주축회전수, 베어링의 지지특성, 베어링의 간격, 주축재료의 내부감쇠율 등의 영향을 고찰하였다.

          터널 순응휘도와 경계부 휘도의 관계 연구

          원범,정준 한국도로학회 2014 한국도로학회논문집 Vol.16 No.3

          PURPOSES : This study has been performed with the objective to determine threshold zone luminance of adaptation luminance by target safety level in a vehicular traffic tunnel with design speed set at 100km/h . METHODS: The study made a miniature capable of portraying changes in luminance distribution within 2×10。conical field of view of the driver approaching to the tunnel for the test. Test conditions were set based on justifications for CIE 88-1990's threshold zone luminance used as a reference by domestic tunnel light standards (KS C 3703 : 2010). Luminance contrast of object background and object is 23%, object presentation duration is 0.5 seconds, and size of the object background is 7.3×11.5m2 RESULTS: Threshold zone luminance was set within adaptation luminance of 100~3,000cd/m2. Adaptation luminance and threshold zone luminance based on 50%, 75% and 90% target safety level all showed a relatively high linear relationship. According to findings in the study, it is not appropriate to specify the relationship between adaptation luminance and threshold zone luminance as luminance ratio. Rather, direct utilization of the linear relationship gained from the study findings appears to be the better solution. CONCLUSIONS : Findings of this study may be used to determine operation of threshold zone luminance based on target safety level. However, a proper verification and validity of test results are required. Furthermore, a study to determine proper threshold zone luminance level considering target safety level reviewed in this study and various decision-making factors such as economic conditions in Korea and energyrelated policies should be carried out in addition. Additional tests on adaptation luminance greater than 3,000cd/m2 will be performed, through which application scope of the test findings will be broadened.

          터널 경계부 휘도수준에 따른 운전자 연령대별 안전수준 비교

          원범,정준화,김도경,박원일 한국도로학회 2015 한국도로학회논문집 Vol.17 No.1

          PURPOSES : The purpose of this study is to suggest a basis for setting appropriate safety goals specifically related to the threshold zone luminance in a vehicular traffic tunnel. . METHODS: In the test, drivers were divided into two groups. One group consisted of all drivers (average drivers) group with an age ratio of drivers holding domestic driver's license and driver group by age to produce threshold zone luminance in the tunnel. The threshold zone luminance produced as a result was used to analyze how it affects the safety level of each driver group and provide a basis for setting an appropriate safety criterion that can be used to determine threshold zone luminance. We used test equipment, test conditions, and ananalysis of threshold zone luminance identical to that reported by ChoandJung(2014) but the values of adaptation luminance in our analys is were expanded to range from100 to10,000 cd/m2. RESULTS : Adaptation luminance and threshold zone luminance are found to be related by a quadratic function. The threshold zone luminance needed by older drivers to ensure a certain safety level is significantly higher than that for drivers of other age brackets when adaptation luminance increases. 56% of older drivers are at an increased risk of an accident at the same luminance for which the safety level of average drivers is 75%. The safety level that can be achieved for older drivers increases to above 60% when threshold zone luminance level is set with the goal of attaining a safety level of more than 85% for average drivers. The safety level that can be attained for average drivers is above 90% when the threshold zone luminance is high enough to ensure over 75% in the safety level of older drivers. Results of this study are applicable to highways and others whose designed speed is 100 km/h. CONCLUSIONS : Threshold zone luminance determined on the basis of drivers having average visual ability is of limited value as a performance standard for ensuring the safety of older drivers. Hence, safety level for older drivers should be considered separately from safety levels for drivers with an average ability to avoid risk. Upward adjustment of older drivers' safety level in the process of determining appropriate threshold zone luminance in a vehicular traffic tunnel may bring both tangible and intangible benefit as a result of reducing accidents. However, there is an associated dollar cost arising from installing and operating lights. As a result, the economic impact of these trade-offs should also be considered.
