  • The prolonged and heavy East Asian summer precipitation in 2020 may have been caused by an enhanced Madden-Julian Oscillation (MJO), which requires evaluation using forecast models. We examined the performance of GloSea6, an operational forecast model, in predicting the East Asian summer precipitation during July 2020, and investigated the role of MJO in the extreme rainfall event. Two experiments, CON and EXP, were conducted using different convection schemes, 6A and 5A, respectively to simulate various aspects of MJO. The EXP runs yielded stronger forecasts of East Asian precipitation for July 2020 than the CON runs, probably due to the prominent MJO realization in the former experiment. The stronger MJO created stronger moist southerly winds associated with the western North Pacific subtropical high, which led to increased precipitation. The strengthening of the MJO was found to improve the prediction accuracy of East Asian summer precipitation. However, it is important to note that this study does not discuss the impact of changes in the convection scheme on the modulation of MJO. Further research is needed to understand other factors that could strengthen the MJO and improve the forecast.

  • Domestic and overseas information with regard to harmful substances are analyzed. From the results, environmental-derived hazard chemicals, which show relatively low recognition, and hazard chemicals that occur unavoidably in food manufacturing process are selected as target harmful substances. Thus, educational leaflet contents were developed based on these substances. To find the effects of education with the above contents, this study surveyed 120 female college students living in Seoul. The purpose of the survey is to analyze the change in recognition, attitude and behavior on hazard chemicals in foods. The survey found that the recognition on harmful substance in foods increased; from 31.5~78.0% before education to 98.8% after education. It also indicates that vague anxiety in which the harmful substances may damage their health decreased by approx. 25.0%; from 77.8% before education to 52.8% after education. For the question of what they would do when government promotes to reduce harmful substances in foods, 12.3% of respondents said that they would actively follow the suggestions and 73.5% of them said that they would do their best before an education. However, 56.1% of them said that they would actively follow the suggestions after the education. It indicates that the ability to recognize harmful substances changed after the education. With regard to consumer behavior, when they knew about the harmful substances in foods, 49.6% of them said that they would select foods after investigating relevant information before the education, while 77.4% of them said that after the education; which is an increase of 27.8%. Further, 45.4% of them said that they would not purchase relevant foods before the education, while 20.9% of them said that after the education; which is a decrease of 24.5%. Therefore, it is considered that vague anxiety of consumers can be eliminated by providing persuasive information on harmful substances. To expand on the communication channel with consumers for food safety, contents development and educational promotion should be enhanced for providing food safety related information.

  • Problem Based Learning (PBL) is one of methods which has been developed to promote student-centered learning and to pursue self-directed learning for life-long learning. The purpose of this study is exploring the possibility of Problem Based Learning (PBL) in college Earth science course. The participants of this study were fourteen students attending an Earth science class at Sookmyung Women's University in Seoul. PBL was implemented in the form of group project with utilizing Web-based course tool. We provided questionnaires and conducted interviews to figure out students' perception about PBL. The findings were as follows: Through a given experiences, (1) students participated more actively than LBL (Lecture Based Learning), (2) more students were engaged with self-directed learning, and (3) students made higher cognitive efforts. LBL seemed to be more efficient way to acquire factual knowledge. In the meanwhile, PBL did not seem to affect the improvement of communication skills. Students could not make use of Web-based course tool effectively in communicating with other team members. In this study, we found that college student participants preferred problems related to everyday life, environmental issues and interesting but unusual incidents. On the other hand, they felt difficult in open-ended problems, especially when they were asked to provide their own evaluation. On the basis of PBL experiment in this paper, we present one method of successful implementation of PBL and suggest topics which should be studied in the future.

  • This study was conducted to evaluate the necessity of clinical nutrition education in the medical school curriculum. One hundred and eighty five medical school students, residents, nurses, and forty undergraduate students majoring in food science and nutrition were involved in this study. The survey included questions about nutritional knowledge, necessity of nutrition counseling, necessity of clinical nutrition and nutritional attitudes. The nutritional knowledge scores of the subjects in medical school and residents were significantly lower than those of the students majoring in food science and nutrition. Subjects of 91.3% strongly agreed to the necessity of nutrition counseling for patients ; 78.9% agreed that the present nutrition education in medical schools was inadequate. Most subjects (94.1%) agreed that clinical nutrition was an important field in the treatment of diseases. The medical profession is facing the challenges of the 1990s with the shift to outpatient care and preventative services. Clinical nutrition is an essential element in the process of curriculum change. The nutrition educator will be expected to take a leading role in integrating clinical nutrition into medical school curriculum.

  • This study aims to develop STS modules which consider the local concerns of Korean society and their authentic evaluation instruments. Their titles are as follows: 'Health-Aiding Foods, are they necessary?', 'Competition between Alien and Native Species', 'Living Lesson of Lake Shihwa', and 'Problems of food wastes; Would you like to throw them away, if they are money?' All of them deal with issues unique to Korean local situations. Each module consisted of two versions; a student worksheet and a teachers' guide. Students' activities were categorized into six processes such as group activities, investigation, discussion and presentation, experiments, field trip, and multiple intelligence activities. Various assessment tools and abilities for the decision-making in their STS classes were also included. In order to validate these modules, 24 teachers who have been teaching science, biology and environmental science in the secondary schools reviewed these modules and provided feedbacks about their validity and usefulness. We expect that the various rubrics included in each module will provide teachers creative and flexible assessment methods for students' understandings and their decision-making abilities toward the issues.

  • The purpose of this study is to find out the differences (if any) and the causes of preferences for science between elementary school boys and girls. Another purpose of this study is to find out when such differences in preference begin and what their causes we. Fourth, fifth and sixth grades from elementary school A in Gyeongg-gi Province participated twice in research surveys on preference levels in science with education, career course and personal experience taken into account. A total of 997 survey responses, (excluding no responses or half-hearted ones) were selected for comparative analysis. The analysis methods used were frequency analysis, cross stabs and one-way ANOVA Analysis which depended on survey items. The results of this study show that preference levels in science are 61.7% and the difference of preference levels in science between boys and girls are 31.2% and 30.5% with boys showing higher percentages in science preference levels than girls(p<.01). Moreover, the results also show that the point in which changes in preference level in science emerges is from fifth and sixth grades. Therefore, the gender difference in preference levels in science begins with fifth grade students, with science being slightly more favored by boys. finally, the main causes in gender differences seems to be the experiment participants' levels, scientific education textbook preference level, interests in science class, and plans for the future that are related to field of science. Among these causes, interests level in science class and preference levels in science are closely related.

  • Constructivism has had a great influence on science education over the last two decades. The purpose of this article is twofold: First, to describe the characteristics of constructivism and, second, to suggest an ideal forms of science education in Korea as implied in constructivism. A review of the literatures in the first area shows that constructivism is philosophical/psychological view which believe in the social nature of the construction of scientific knowledge and its learning. And the analyses of a few schools of constructivism suggest decision-making as a goal of science education, learning as the active construction of meaning through interaction between learner and learning environments, and discussion and cooperation as appropriate teaching strategies. At the same time, the results necessitate teaching ethical aspects of science in the secondary schools, and also imply that performance assessment must be emphasized in evaluation of science education.
