  • The effects of learning using Information Communication Technology(ICT) on the students' scientific inquiry ability and science-related affective characteristics were analyzed in Earth History and Crust Movement units of science textbook for eighth graders. For this study, two classes of middle school second students in Chung-nam were selected and taught for six week under different teaching methods. One class is the test class taught with ICT applied teaching materials and the other class is the control class instructed by a conventional method. One week before the experiment, both classes were given tests on scientific inquiry ability and science-related affective characteristics, and they were tested again after the experiment. The results of scientific inquiry test showed statistically meaningful differences in the experimental class and the control class. The experimental class showed statistically meaningful difference in scientific inquiry test. Science-related affective characteristics test showed no statistically meaningful difference in the experimental class. Among three scientific science-related affective characteristics, especially the one fields of interests showed statistically meaningful differences which suggest that learning using ICT has a positive effect on the expanding of students' science-related affective characteristics.

  • In this case study, we analyzed the processes of STEAM lessons conducted by preservice secondary science teachers. Three preservice science teachers at a college of education in Seoul participated in this study. After the workshop for STEAM education, they planned and practiced STEAM lessons. All of the teaching-learning materials were collected before lessons, and their lessons were observed and videotaped. Semi-structured interviews were also conducted before and after their lessons. The processes of STEAM lessons were analyzed while focusing on PCK and PDC. Their difficulties, needs, and views on STEAM education were also studied. It was found that they have taken much efforts to reflect the objectives and characteristics of STEAM education, and prepared teaching-learning materials by searching on the internet and arranging creative contents. Their great difficulty was to determine topics for STEAM lessons. While one preservice teacher satisfied with her lesson perceived STEAM education positively, the others perceived that it would be very difficult to practice STEAM lessons in school. For their STEAM lessons to be successful, the workshop needs to include some specific information on grades, proper topics for each grade, ways of making materials, and tips for effective STEAM lessons. In addition, it will be effective if the workshop is carried out after their study on constructivist learning theory and if they experience successful STEAM lessons.

  • The purpose of this study was to develop the customized diet education game (Roly-Poly 160) for type II diabetes and to test its effectiveness. The diet education game for type II diabetic is composed of three kinds of modules as Meal self-management, Card Game, and Quiz Game. Meal self-management was developed to manage the dietary information of each day and to observe changes in the 12-month period. Card game is to find a changed card based on the recommended meal menu during a limited time and Quiz game is to learn knowledge while solving the quizzes about diet. Data was collected from September 28th to October 28th, 2016 at C hospital and G hospital in G district, and 5 times for 1 hour for every 30 people with type II diabetes who applied for diabetic diet education. Knowledge of diabetes and 2 hour postprandial blood glucose were measured repeatedly before and after the experiment. After the Roly-Poly 160 experiment, the knowledge of type II diabetes was statistically significantly increased (p = 0.04), and the fasting blood glucose and the 2 hour postprandial blood glucose decreased statistically decreased (p <.05) and Roly-Poly 160 game clinical efficacy was verified.

  • This study was carried out to determine the factors affecting the trend and usage of Magnetic Resonance Imaging before and after the implementation of National Health Insurance. The research materials were the MRI Execution Data, Health Insurance Review Data, and Medical Expenses in the Health Insurance Data from a General Hospital located in Dae-jeon Metropolitan City from 2004 to 2013. The subjects of analysis were 3,754 people in 2004 (prior to the implementation of Health Insurance), and 4,107-8,603 people from 2005-2013(after the implementation of Health Insurance). In terms of analysis, a comparison of the use of MRI before and after implementation of the Health Insurance of User Characteristics and Provider Characteristics were taken as $X^2$, while factor analysis for the elements that affect MRI usage was carried out by Hierarchical Multiple Regression Analysis. According to the results of this study, the level of use decreased temporarily in the initial application stages of the national health insurance, but it soon increased. In particular, the inspection rates for women, the head and neck, those not subject to the application of the national health insurance, internal medicine, and the inpatients increased. The application of the national health insurance for MRI influenced the increasing inspection rates (P<.0001). As the inspection rate for the MRI increased, it is important to expand the application of the national health insurance to reduce the national health expenditure.

  • Proximate compositions of muscles and eggs between wild sweet smelt which were caught in Seomjin river and Miryang river, and cultured sweet smelt which were purchased from certain cultured farms in Hadong and Miryang, were compared. Proximate compositions of wild sweet smelt muscles were $76.7\~77.5\%$ for moisture, $18.4\~19.9\%$ for protein, $2.41\~3.47\%$ for lipid, and $1.04\~1.33\%$ for ash content and there were almost no differences between the fishes from Seomjin and Miryang river. Protein and ash content in the cultured fish muscles were similar to those of the wild fish muscles, while the former contained much more lipid and carbohydrate, and less moisture than the latter, especially lipid content differed greatly according to their cultured farms. This might be the result of their different diet compositions. Lipid, protein and carbohydrate content in eggs of the wild and cultured fishes were much higher than those in their muscles. There was a negative correlation between moisture and lipid content in all samples; y= -0.2715x+24.903 (r= -0.7253, p<0.001).

  • Anti-oxidant activity of 600 medicinal plants from Jeju was analyzed. Extracts from the leaves of Distylium racemosum have the highest anti-oxidant activity. D. racemosum is an oriental medicinal plant belonging to the Hamamelidacea and grows in the wild in Jeju. This study was conducted to evaluate the antioxidant and cell viability of different fractions (n-hexane, methylene chloride, ethyl acetate, buthanol, DW) from D. racemosum. Anti-oxidant activity was measured using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity test and total phenolic content. Cell viability was determined by 3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide (MTT) cell viability assay on HepG2 and A549 cells. Among various extracts, the ethyl acetate fraction showed the highest DPPH radical scavenging activity, reaching approximately 93% at 0.5 mg/mL, higher than that of quercetin used as a positive control. Ethyl acetate fractions showed the highest total phenolic content at 505 mg GAE/g. The phenolic content of each extract showed association with DPPH radical scavenging activity. The ethyl acetate extracts were resistant against hydrogen peroxide ($H_2O_2$) treatment in the MTT cell viability assay and showed a higher cell protective effect than other fraction extracts. These results suggest that the ethyl acetate fraction might be a source of anti-oxidants of D. racemosum.
