  • The purpose of this study was to develop a STEAM-based science education program for children and to verify its effectiveness. An S-STEAM-based science education program for young children was developed through careful analysis of prior research on science education for young children and S-STEAM. The participants were 29 four-year-old children from daycare centers located in Seoul (an experimental group of 14 and comparative group of 15). The S-STEAM program was applied to the experimental group, while the control group went through a general science education course provided by the government. TTCT of Creative Thinking (TTCT: Figures A and B) was used as a research tool, and a multiple intelligence test tool was applied to teachers of the groups. Afterwards, analysis of covariance was implemented to find the S-STEAM program's effects. First, the results showed positive effects on overall creativity, as well as in fluency, originality, abstractness, elaboration, and openness components of creativity. Second, the results showed positive effects on overall multiple intelligences and its components of linguistic, musical, spatial, logical/mathematical, physical exercise, interpersonal, and naturalist intelligence.

  • Our educational system clearly places much greater value on left hemisphere learning. Students who process information in other ways are at a serious disadvantage and may not be learning efficiently. Since mind mapping emphasizing visual and spatial language, it helps students to use the whole brain and promotes more effective comprehension. The purpose of this research was to determine the effects of the instruction using mind map on the science achievement of students. A pretest-posttest control group design was employed. Subjects were 153 male and female, first grade students in a middle school. A control group of 83 was instructed with a traditional teaching method, and an experimental group of 70 was instructed by using a mind mapping strategy. Two groups were treated for 50 hours during 17 weeks. Tolerance's 'Style Of Learning And Thinking(SOLAT)' was used to assess students' lateralization preferences. A 30-item multiple choice posttest was used to assess students' achievement. To analyze the data, we used an analysis of covariance(ANCOVA) and i-tests. It was found that 21.6% of students was left brain dominant, 31.4%, right brain dominant and 47.1 % was integrated style. There was no gender difference in hemispheric dominance. Significant differences existed between the test scores when they were taught by using a mind map. Mind mapping turned out to be a valuable learning technique for the right brain students, helping them to achieve the same level of subject mastery as left brain students. There was a significant difference between males and females in relation to mind map application. Female scored significantly higher than males.

  • This study presents strategic implications for enhancing the competitiveness of the comprehensive health examination center through the study of its impact on the switching barrier with medical service value and medical service satisfaction as parameters. In order to achieve the purpose of this study, a total of 324 questionnaires were analyzed for customers who received health examinations at the general examination center. Covariance structure analysis was performed to test hypotheses and causal relationships. The results showed that the physical environment had a significant effect on the medical service value and medical service satisfaction. The value of medical service also had a significant effect on medical service satisfaction. The value of medical service was found to affect the transition barrier, but the satisfaction of medical service did not affect the transition barrier. The implications of this study are that physical environment has a significant effect on medical service value and medical service satisfaction. Therefore, modern medical equipment should be equipped with the latest medical equipment to minimize accurate examination and misdiagnosis through modernization of medical examination center. In addition, since the value of medical service has a significant effect on the switching barrier, it is necessary to establish a plan to enhance the value of medical service. We need to promote sustainable customer retention and creation of new customers through differentiated screening items and cost advantages over competitors. In addition to check-up services, efforts should be made to enhance the value of services such as strengthening medical communication and medical complex cultural spaces, and at the same time, establish an organizational culture of customer-first examination centers through the placement of excellent personnel and continuous education.

  • This study analyzed the differences in parents' perceptions toward children's adjustments after grade skipping and early graduation. Parents of an early entrancer to K university(n=43) and parents of a non-early entrancer to K university(n=12) responded two kinds of questionnaires, one is for parents' perceptions towards children's needs for grade skipping and early graduation, and the other is for parents' perceptions toward children's adjustments to university experiences. Parents' responses were analyzed by MANOVA and MANCOVA. Results indicated that there was the significant difference in parents' perceptions for 'information about early graduation.' That is, parents of an early-entrancer had more 'information about early graduation' than their counterparts. However, there was no significant difference in parents' perceptions, after the effect of 'information about early graduation' on parents' perceptions toward children' academical and social-emotional adjustments. Thus, parents having more 'information about early graduation' considered more seriously the needs of grade skipping and early graduation in their children and worried less about their children's adjustments to university experiences.

  • The aim of this study was to examine whether health promoting behavior was dependent on perceived health status and health attitude in adults, and whether health concern mediated the relationships among these variables. Structural equation modeling was applied to test a model in which perceived health status and health attitude were considered as exogenous variables while health concern as a mediating variable. The participants were 292 adults aged from 20 to 59 and completed the self-report measures. The results of the structural equation model showed that perceived health status and health attitude were positively associated with health concern and health promoting behavior. Health concern mediated the relationships between perceived health status and health promoting behavior, and also health attitude and health promoting behavior. The findings suggest that enhancing health attitude may play important roles to promote health promoting behavior in adults, and the development of various health education for adults in schools, work place, and health and medical organization might promote positive health attitude and health concern. Health education program in connection with preventive health examination also might contribute to activate health promoting behavior.

  • This study aimed to identify appropriateness and efficiency in the DRG payment system by analysing the hospital length of stay and changes in fees before and after the application of DRG payment system. The subjects of the study were a total of 398 patients consisting of 204 for the fee for service system and 194 for the DRG payment system. They received surgery in the Obstetrics and Gynecology (OBGY) department of a general hospital in G metropolitan city between January and December 2013. The mean hospital length of stay was significantly decreased after application of the DRG payment system(p=0.013). Total fees, insurance charges, and deductions increased significantly(p<0.001), and non-payment charges and total deductions decreased significantly(p<0.001). Application of the DRG payment system reduced length of stay, non-payment charges and total patient's cost sharing and increased out-of-pocket, insurance charges, and total fees.

  • There are two types of clinical research to figure out risk factor for disease using collected data. One is prospective study to approach the subjects from the present time and the other is retrospective study to find the risk factor using the subject's information in the past. Both approached and study design are different but the purpose of the two studies is to identify a significant difference between two groups and to find out what the variables to influence groups. Especially when comparing the two groups in clinical research, we have to look at the difference between the impact clinical variables by group while controlling the influence of the baseline characteristics variables such as age and sex. However, in the retrospective study, the difference of baseline characteristic variables can occur more frequently because the past records did not randomly assign subjects into two groups. In clinical data analysis use covariates to solve this problem. Typically, the analysis method using the analysis of covariance of variance, adjusted model, and propensity score matching method. This study is introduce the way of equality adjustment between groups data analysis using covariates in retrospective clinical studies and apply it to the recurrence of gastric cancer data.

  • This study used the third wave of individual data of KReIs(Korean Retirement and Income Study) because the third wave of data only had the necessary variables which fit into this study. The data was collected in 2010 using national random sampling. The target population was adults who are older than 65 and the sample size of this study was 4,080. The factors of successful aging were compared by the recognition of old age (group (1): people who recognize they are not older adults(n=620); group (2): people who recognize they are older adults(n=3,460)). For comparison of each variable by the recognition of old age, t-test, chi-square test and ANCOVA were used depending on the types of variables. To test the effect on the life satisfaction of the factors of successful aging, hierarchical regressions were used for each group. 1) Except for the number of leisure activities, older adults who recognized they were not old(group (1)) had a higher level of factors composing of successful aging than older adults who recognized they were old(group (2)). 2) For group (1), age did not affect their life satisfaction in a statistically significant level, but for group (2) age negatively affected their life satisfaction. 3) The results indicated that cognitive and physical functioning were more important than avoiding disease and disability. 4) For group (2), IADL affected life satisfaction positively in a statistically significant level, but for group (1), IADL did not affect life satisfaction. 5) For group(2), whether they had a job or not affected the life satisfaction differently.

  • In order to establish B. tabaci control in paprika greenhouses a fixed-precision-level sampling plan was developed. The sampling plan consisted of spatial distribution analysis, a sampling stop line, and decision making. Sampling was conducted simultaneously in two independent greenhouses (GH 1, GH 2). GH 1 and 2 were surveyed every week for 22 consecutive weeks, using 19 sampling locations in GH 1 and 9 sampling locations in GH 2. The plant in both greenhouses were divided into top (180-220 cm from the ground), middle (80-120 cm from the ground) and bottom (30-70 cm from the ground) sections and B. tabaci adults and pupae were observed on three paprika leaves at each position and recorded separately. GH 2 data were used to validate the fixed-precision sampling plan, which was developed using GH 1 data. In this study, spatial distribution analysis was performed using Taylor's power law with the pooled data of the top and bottom position (B. tabaci adults), and the middle and bottom positions (B. tabaci pupae), based on a 1-leaf sampling unit. Decision making was undertaken using the maximum of action threshold in accordance with previously published method, and the value was decided by the price of the plants. Using the results obtained in the greenhouse, simulated validation of the developed sampling plan by RVSP (Resampling Validation for Sampling Plan) indicated a reasonable level of precision.
