박강,김정국,박재현,Park Kang,Kim Jung-Kuk,Park Jae-Hyun 한국공학교육학회 2000 공학교육연구 Vol.3 No.2

한국공학교육인증원이 발족되어 각 프로그램에 대한 인증작업이 시작되었으나 이를 준비해야 하는 교수진들은 인증 준비절차에 대한 실무적인 사례가 부족하여 많은 어려움을 겪고 있는 실정이다. 본 논문은 전체 인증 준비과정 중에서 프로그램 교육목적과 학습성과를 선정하는 과정을 구체적으로 제시하고자 한다. 프로그램 교육목적은 교육수요자들의 요구, 교육기관의 교육목적 및 특성, 프로그램별 특성을 반영한 구체적이고 평가 가능한 목적이어야 한다. 프로그램 학습성과는 한국공학교육인증원이 제시한 12가지 학습성과에 프로그램의 특성에 맞는 학습성과를 추가하여 완성하였다. 프로그램 교육목적과 학습성과는 각 과목의 교육목적 및 교육기관의 교육목적들 간에 서로 연관성이 확보되어야 하므로 상관관계분석표를 통하여 연관성을 확인하였다. Even though Accreditation Board of Engineering Education in Korea (ABEEK) started its accreditation procedures, the faculty still have difficulties in preparing the accreditation because there are little practical examples of the preparing procedure. This paper explains the practical procedure to determine the educational objectives and the outcomes, which is the first part of the accreditation preparing procedure. The educational objectives of the program should be expressed by the specific and assessable sentences and their contents should comply with the demands of the educational community, the objectives of the educational institute, and the characteristics of the program. The program outcomes consist of 12 outcomes from ABEEK and additional outcomes that reflect the characteristics of the program. Since the educational objectives and the outcomes should have the full connection among the objectives of the institute and the course objectives, the relationships among them should be checked using the relationship analysis matrix.

This paper aims to compare the effects of two teaching methods, the discovery-observational(DO) and the expository-observational(EO) instructions, on students learning interest in the life cycle of fruit fly. The subjects, 463 third-graders from two elementary schools in Changwon City, were divided into two groups, the DO group and the EO group. After the instruction on the life of the flies in two different teaching ways, a questionnaire with 13 items was devised regarding the students` interest, and the subjects were asked to respond to it. The results reveal that the general mean score of the DO group is higher than that of the EO group. Also, the DO group obtains the higher mean score in each item, except two items about knowledge learning. The differences of the mean scores of the two types, general as well as item-individual, between the two groups are statistically significant. This suggests that the class about the life cycle of living creatures easily getatable and observable, such as fruit flies, should be student-centered investigatory one, where students themselves collect them and observe the process of their growth and whole cycle.

박강은(Kang Eun Park),정화숙(Hwa Sook Chung),송승달(Seung Dal Song),노광수(Kwang Soo Roh),송종석(Jong Suk Song) 한국식물학회 1995 Journal of Plant Biology Vol.38 No.4

The effects of 0.5 and 1.0 ppm of ozone on the developing chloroplast of barley (Hordeum vulgare L.) seedling during greening were investigated by PSⅠ and Ⅱ activities, chlorophyll fluorescence, and the contents of chlorophyll. Etiolated barley seedling was treated 0.5 and 1.0 ppm ozone for the first 4 h during greening. In 24 h greening experiment, the contents of chlorophyll were decreased by increasing ozone concentration from 0.5 ppm to 1.0 ppm. In 24 h greening experiment, Fo, Fv, Fm and qE were greatly decreased as the concentration of ozone was increased, but those were not considerably decreased in 48 h greening experiment. In another experiment, the developing barley seedling was treated with 0.5 and 1.0 ppm ozone for the last 4 h during greening period, which was 24 h or 48 h. In both experiments the PS Ⅱ activity was decreased as the concentration of ozone was increased, but not in PS Ⅰ activity. Fv, Fm and Fv/Fo were also decreased as the concentration of ozone was increased. qP and qR were strikingly decreased as the concentration of ozone was increased in both experiments.

시금치 엽록체의 광합성 전자전달 활성에 미치는 Cd2+ 의 저해 효과

박강은(Kang Eun Park),정화숙(Hwa Sook Chung) 한국식물학회 1994 Journal of Plant Biology Vol.37 No.2

The effect of Cd^2+ on the electron transport rate of PSⅠ and PSⅡ was investigated in isolated spinach chloroplasts. In photosystem Ⅱ, the rate of electron transport was decreased as the concentration of Cd^2+ was increased from 1 to 100 μM. The inhibitory effect of Cd^2+ was reduced when diphenylcarbazide was added to the reaction medium, indicating that Cd^2+ affects primarily PSⅡ oxygen evolving complexes of thylakoid membrane. The inhibitory effect of Cd^2+ was reduced when Mn^2+ and Ca^2+ were added to the reaction medium, but the inhibitory effect was not fully relieved. Although the activity of PSⅡ was decreased significantly by the treatment of 50 μM Cd^2+, Fv/Fm was decreased slightly. However, the treatment of 100 μM Cd^2+ resulted in the marked decrease of Fv/Fm. In hotosystem Ⅰ, the rate of electron transport decreased as the concentration of Cd^2+ was increased from 0.2 to 3.2 mM. The inhibitory effect of Cd^2+ was decreased when the chloroplast treated with Cd^2+ was washed by centrifugation.

This paper proposes a hybrid visual servoing algorithm for the object tracking by a mobile robot with the stereo camera. The mobile robot with the stereo camera performs an object recognition and object tracking using the SIFT and CAMSHIFT algorithms for the hybrid visual servoing. The CAMSHIFT algorithm using stereo camera images has been used to obtain the three-dimensional position and orientation of the mobile robot. With the hybrid visual servoing, a stable balance control has been realized by a control system which calculates a desired angle of the center of gravity whose location depends on variations of link rotation angles of the manipulator. A PID controller algorithm has adopted in this research for the control of the manipulator since the algorithm is simple to design and it does not require unnecessary complex dynamics. To demonstrate the control performance of the hybrid visual servoing, real experiments are performed using the mobile manipulator system developed for this research.

The purpose of this study was to investigate elementary and middle school student's misconception on magnetic field of interaction of two bar magnet. A survey was conducted of total 250 including 154 3rd and 6th grade elementary students and 96 3rd grade middle school students in February when learning about the unit of the magnet was completed. The models were provided deciding the classification standard by investigating the conception of the magnetic field in case two magnets are put according to Anderson's classification standard the misconception of the magnetic field about two bar magnets. We compared the types and the levels of the misconception of the magnetic field by each grade. We divided the model of the misconception of the magnetic field into 4 models including partial distribution model, pole separation model, homogeneous distribution model and field model and then the sub-model was prepared to represent the model. The response rate of each model had differences depending on disposition of the magnet. The response rate of homogeneous distribution model was highest, and appeared in the order of field model, partial distribution model, and pole separation model. For the response rate by each academic grade, in case of partial distribution model, elementary 3rd graders were highest, and it appeared in the order of elementary 6th graders, and middles school 3rd graders. In pole separation model, mainly elementary 6th graders appeared highest. In homogeneous distribution model, elementary 6th graders appeared highest and it appeared in the order of elementary 6th graders, and middles school 3rd graders. In field model, middles school 3rd graders were highest, and it appeared in the order of elementary 3rd graders, and elementary 6th graders. In the response rate of field model by each academic grade, elementary students were remarkably lower than middles school 3rd graders.
