  • Purpose of this study is to clarify the effect of creative science writing for interest of biology and scientific attitude on high school student. Creative science writing is a learning method to enhance comprehension and expression of thinking of science contents related to daily life. 148 students were recruited and divided into two groups, experimental group were experience creative science writing lessons. On the other hand, contrary group were applied interest enhancement lessons excepted creative science writing activity. To investigate the effect of creative science writing, interest check of biology was used, and scientific attitude test was used to understand changes in student's scientific attitude. Experimental group had taught using creative science writing and their awareness of the instruction was analyzed with questionnaire. As a result of this study, the class based on creative science writing was effective in improving high school students' interest in biology and in particular it was helpful in promoting interest in biology and learning of biology. It suggested that the class based on creative scientific writing used a new teaching method unlike existing methods, caused them to have interest in the instruction by making them express their daily life freely not to memorize learning contents, applied learning contents to daily life through many kinds of writings and then enhanced their interest in biology. Indeed, the class based on creative science writing had the positive influence on changes in the scientific attitude of high school students. Since creative science writing is writing one's own idea through extensive thinking based on learning contents, it was effective in arranging the process of thinking and changing their scientific attitude into positive one. Consequently, it was concluded from the above results of the research that the teaching using creative science writing was available as the effective teaching methods to improve high school students' interest in biology and change their scientific attitude into positive one.

  • The etiology and pathophysiology of delayed inflammatory reactions caused by hyaluronic acid fillers have not yet been elucidated. Previous studies have suggested that the etiology can be attributed to the hyaluronic acid filler itself, patient's immunological status, infection, and injection technique. Hyaluronic acid fillers are composed of high-molecular weight hyaluronic acids that are chemically cross-linked using substances such as 1,4-butanediol diglycidyl ether (BDDE). The mechanism by which BDDE cross-links the two hyaluronic acid disaccharides is still unclear and it may exist as a fully reacted cross-linker, pendant cross-linker, deactivated cross-linker, and residual cross-linker. The hyaluronic acid filler also contains impurities such as silicone oil and aluminum during the manufacturing process. Impurities can induce a foreign body reaction when the hyaluronic acid filler is injected into the body. Aseptic hyaluronic acid filler injections should be performed while considering the possibility of biofilm formation or delayed inflammatory reaction. Delayed inflammatory reactions tend to occur when patients experience flu-like illnesses; thus, the patient's immunological status plays an important role in delayed inflammatory reactions. Large-bolus hyaluronic acid filler injections can induce foreign body reactions and carry a relatively high risk of granuloma formation.

  • The purpose of this study is to investigate the effects of science classes using smart devices that combine augmented reality (AR) and virtual reality (VR) on the scientific attitude of middle school gifted students. In addition, it is intended to find out the perception of science classes using these smart devices. In addition to actual experiments, a science class program that allows students to experience science experiments virtually using AR and VR was applied to 15 middle school gifted students. Before and after the application of the program, the questionnaire is to investigate the interest in scientific classes, the attitude toward science exploration, and the professional interest in science, and the recognition of classes that combine AR and VR. In addition, through in-depth interviews, the perceptions of gifted students was accurately investigated. As a result of this study, the content of science classes and instructors showed high class satisfaction, but the smart devices and applications used during the science classes showed lower class satisfaction than others. As a result of comparing and analyzing the pre-post of gifted students, interest in science class, attitude toward science inquiry, and professional interest in science increased significantly among the sub-areas of the scientific attitude test. As a result of analyzing free responses and indepth interviews, gifted students responded with the advantage that classes using smart devices that combine AR and VR can be tested quickly and safely for a short time compared to actual experiments. On the other hand, they responded with low completeness of the application and dizziness when operating virtual reality. Based on this, implications for the development of applications and instructional programs using advanced technologies that can experience realistically limited scientific experiments such as experimental preparation, class time, and risk factors were obtained.

  • This study aims to investigate the impact of science classes employing creative science drama on elementary school students' academic achievement and attitudes toward science during the final step of elementary science classes. The creative science drama used in this study is a class-closing activity wherein the teacher provides a basic script for the learning topic and then allows students to complete the rest of the story using their assignment. It devised a creative science drama class based on the research of Yoon (2016), and the contents of this study were centered on the use of magnets and the appearance of the Earth in the first semester of third grade. Students in their third year at H Elementary School in Gyeonggi-do were the subject of this study. The results showed that scientific achievement through science drama in the experimental class was improved, with a statistically significant difference. However, ANCOVA analysis revealed no statistically significant differences in attitudes toward science. Moreover, there was no statistically significant difference in scientific drama perception. Interviews with students in the experimental class applying science drama revealed that students found difficulty in writing science drama scripts and that coordinating and reaching a mutually acceptable opinion in group activities required the most discussion and cooperation. However, many of them stated that the experience of scientific drama was enjoyable and informative, and since what they learned was transformed into a scientific drama, they remembered the lessons longer.

  • This study researched the concepts that elementary school students have after having learned volcano and earthquake. The reacher collected and adjusted the journals related to this study, and sampled the concepts included in Chap. One "Moving Earth", the first term of the elementary school sixth year. The students' descriptive responses were analyzed after subjective questions on the basis of above were developed and put into. After the contents described in the answer sheets were categorized by key words and the types of concept were made out by qualitative analysis, it was showed what was differences between the sexual, regional and achievement levels. The results of this study were as follows; first, though the types of concept about volcano and earthquake were found variably, it was showed that wrong preconception was not corrected, especially the exact understanding about terms not attained to, which led to the trouble in conceptual readjustment of students. Second, though the response rate about the types of scientific concept was found high that volcano was made out of explosion and eruption of magma and lava, there were also children who described not the interior factor of globe but the surface factor. Third, according to the results divided into the interior factor of globe and the surface factor and analyzed about earthquake, there were a great number of children who responded as the surface factor though most of the students responded to the interior factor of globe. Fourth, through some types of concept, it was found that the formation of concept was much influenced by experience of children's life, curriculum, and the method of study. Fifth, In the most test question, the scientific concept was found that boys were higher than girls in the distinction of sex, the children of cities than those of town and island, and the upper group than the lower group in the achievement levels.

  • Objective : To find a collaboration strategy between western medicine and traditional Korean medicine (KM), this study aims to figure out the changes in the perception and attitude of medical doctors toward KM through systematic review. Method : Systematic literature searches were performed on six Korean databases. Studies were categorized according to the respondents and question items and analyzed by the context of questions, similarity of respondents and measurement scale. And we analyzed the changes of response regarding to medical doctors' and medical students' perspective and attitude to KM. Results : Eighteen survey studies including attitude of medical doctors and medical students toward KM were selected, which were conducted from 1993 to 2011. Although the attitude toward KM did not show any positive change, medical doctors have had more interest in acupuncture than herbal medicine and appreciated KM's treatment effect for musculoskeletal disease. In spite of little KM education experience, they had intentions for acupuncture education at least. Many medical doctors have listed the unscientific aspect as a major reason why they cannot trust KM. Medical doctors working for cooperative practice showed more positive attitude than other medical doctors and medical students had more positive attitude in general than medical doctors Conclusion : Though the growth of KM service and cooperative practice since 1990s, medical doctors' attitude toward KM seems to become more negative. To improve their attitude, making scientific evidences for KM is required as well as giving more education and treatment experience.

  • Despite the fact that the sourcing process in B2B e-Marketplaces is one of the most important tasks, the evaluation and selection process of suppliers have been ad-hoc based and mainly dependent on the experience of sourcing managers' subjective knowledge. To remedy the problem, we developed a decision support System (called Wise - I) that helps sourcing managers evaluate suppliers in a more systematic way. The system reflects company's strategy and know-how by adopting company enforced weighted scores for different factors and employing a more scientific method of considering factors other than price and on-time delivery rate, utilizing the AHP method. This paper reports the effectiveness of the system as well as the detailed description of the system. To investigate the effectiveness of the system, we collected information through interview and questionnaire survey. The information was also augmented through the firm key index system, which monitors average delivery lead time and on-time delivery rate. The result indicates that the system leads to the efficiency of purchasing section and the transparency of buying process, therefore reduces delivery time and cost.
