  • The purpose of this study is to investigate the effect of social capital on Goendang(relatives) culture, which is a traditional local community culture, and local development as a positive factor. In order to evaluate the effect of social capital, a survey targeting 600 Jeju residents was conducted and 594 returned questionnaires were interpreted for the final analysis. Descriptive analysis, T-test, ANOVA analysis, and multiple regression analysis were conducted on the collected data, using SPSS 18.0. As a result, firstly, the levels of social capital of the surveyed appear as follows: network (average score 4.01), trust (average score 3.80), norms (average score 3.43), cooperation (average score 3.00), and participation (average score 2.80). Secondly, there are differences in social capital among the surveyed groups based on urban-rural areas, administrative districts, and average monthly income. Finally, among the dimensions of social capital, as the relative importance of network and participation increases, the surveyed think that they need Goendang culture more. Also, i t turns out that as the relative importance of norms and participation increases, Goendang culture can exert influence on local development as an important influence factor. Therefore, based on the analysis, this study shows that nurturing social capital can allow people to utilize Goendang culture for local development as a positive community culture.

  • March-June 2010 I hospitals and N of 22 patients in the hospital by DXA and QCT BMD measured at the same object were compared, statistical methods SPSS for Windows program (version 12.0) using the frequency analysis and t-test with a bone age, height, weight, the correlation analysis results were as follows. The distribution of study subjects 19 cases were male and 3 female patients, total 22 patients, 37 years of age ranged from 28 years of age. The mean age of 32.14 years old, and their average height is 170.59 cm, with the average weight was 69.41 kg. In addition to DXA and QCT of how the L2-L4 BMD in level average correlation coefficient was 0.378 with a significant quantitative correlation. Analysis by age rather than the QCT method to DXA showed that 10.8% more valuable, than height level analysis to DXA, QCT method showed 3.4 percent more useful, weight level analysis to DXA is more useful than the 1.2% QCT method was. More results from this study to measure bone density in the DXA method is useful in the age and height and weight by some in the QCT method proved to be useful. Therefore, bone mineral density in patients' age, height, weight, depending on the selection of accurate measurement is considered to be considered.

  • Attention deficit hyperactivity disorder (ADHD) students' intellctual defects, learning problems, and poor academic achievements seem to be due to significantly lower intelligence compared to the normal students, but rather the characteristic of inability to pay attention at a given time can be seen as the more attributing reason. In this study, a comparison between the ADHD students and the normal students will be performed using a fMRI analysis in order to differentiate the brain function between the two groups during a working memory task performance and to assess the difference in the activated regions of the brain. Clinical survey examinations and fMRI measurements were performed for a group of 26 elementary students from the Incheon area. The stimulus of fMRI was a working memory. Cartography statistically analyzed parameters and the Statistical Package of Social Sciences using single-sample t-test, two-sample t-test, were analyzed by multiple regression analysis, the statistical significance level was p<0.05 in, respectively. The disproportionate developments could be seen in the ADHD students group such as the frontal cortex, parietal cortex, thalamus, and caudate nucleus, among others. In addition, as some students felt the increase in the difficulty of working memory task performance, the orbitofrontal cortex and the hippocampus were activated, which seems to be the result of an effort for looking for an answer. More types of ADHD students needs to be secured as research subjects, and more stimulations for fMRI experiments should be considered as it would be useful in the overall evaluation of brain function.

Therefore the purpose of this study was to identify consumer preference by gender in two segmented group; $20{\sim}34$ aged group and $35{\sim}49$ aged group toward men's apparel consumers, considering target customers and female influences on men's wear purchasing. We used questionnaires that were distributed to 600 males and females aged in their 20s to 40s, using stratified sampling method. Only 547 reliable questionnaires were selected for statistical analysis. Chi-Square and t-test were used to analyze the data, using SPSS program. We obtained the following results: 1. We found that there was a significant association between segmented age group and the preference of men's jacket style. Specially $20{\sim}34$ aged group had a significant association with styles of formal jacket, casual t-shirts, casual pants, but $35{\sim}49$ aged group had formal pants style. Looking at the general percentage, semi-formal jacket, slim fit t shirt, straight casual pants were the most favored styles. 2. Age has an significant effect on the preferences of formal menswear fabric patterns and shirt patterns. The results of t-test showed that there found to be significant by gender in character and check pattern of shirts. 3. In design details, the number of button had not significance by gender, and 2 buttons was th most favored by both age groups. The number of gather at the waist had an significant association in $34{\sim}49$ age group. $20{\sim}34$ age group prefer high waist of pants, while $35{\sim}49$ age group prefer low waist of pants. 4. For on time outfit, formal wear and tie ensemble was the most favored with significant difference by age and gender. Formal wear and no tie ensemble favored by about one third of respondents, and more favored by the younger group. For off time outfit, casual jacket and casual pants ensemble was the most favored.

  • In a situation where the recognition of archival services remains minimal, an evaluation of archival information services by users could provide a better understanding of users' practical needs and present helpful information for improved services. A service evaluation by users using questionnaires was conducted in university archives, which can similarly categorize their user groups and have frequent interactions with the users for the provision of services. Questionnaires suitable for the evaluation of university archives were developed based on the review of the evaluation tools in archival information services. From April to October 2015, 113 users' evaluation results were collected from 13 university archives. As a result of goodness of fit tests, the users' service evaluation items were categorized into four parts: Use Results, Provision of Information on Archives, Accessibility to Archives, and Interaction. For those four parts, evaluation by descriptive statistics, T-test, correlation analysis, and regression analysis were conducted. Users evaluated Interaction parts highly while they were less satisfied with Provision of Information on Archives. T-test results showed that university archives with search engines and with electronic records management systems were evaluated higher than archives without such technology. In the regression analysis, the Interaction and Provision of Information on Archives parts were found to have an influence on the Use Results part.

  • This study aimed to extract the priority safety improvement factors for coastal passenger ships and analyze the perception gap between groups. To extract the improvement factors, we formed an expert group with maritime safety supervisors, passenger-ship safety inspectors (PSIs), and captains of passenger ships, and then conducted a Delphi survey. We found, using a hierarchy process, that the improvement factors were divided into three factors in Level 1 and ten factors in Level 2. For the relative importance analysis using the AHP (Analytic Hierarchy Process) model, we also formed two groups: an inspector group with maritime safety supervisors and PSIs, and an examinee group with safety managers, captains, and crews. Consequently, the factors of designation of public transportation for passenger ships and supporting the welfare of the crew were evaluated as the most important among the extracted factors. We conducted a t-test for the analysis of the perception gap between the two groups. Three perception gaps were found: increasing the inspection personnel, strengthening the qualification of the inspection personnel, and expanding the safety operation center. The result of this study will be useful for improving the safety policy of coastal passenger ships.

  • We(Hansol EME Co. Ltd.) proceeded anaerobic digestion test for domestic food wastewater applying to two operating method for increasing of OLR. The methods are as follows. One was the rapidity operating method which was increasing the OLR continuously and rapidly and the other was the terraced operating method which was increasing the OLR having adaptation period for each step. As a result of this tests, the ratio of VFA/Alkalinity of the process was very unstable under the rapidity operating method then the volume of produced biogas was dramatically decreased. However the process was shown stable performance under the terraced operating method maintaining the ratio of VFA/Alkalinity less than 0.4. Also, the process was performing the biogas recovery of $0.8Nm^3/kgVS_{rem}/d$ and the VS removal ratio of 85%. T-RFLP analysis about the community of bacteria and methanogen is also conducted to check the change of the microbial community according to the methods of OLR increasing operation. The microbial community was changed by the methods of OLR increasing operation according to the result of T-RFLP analysis. Although the anaerobic digestion test was executed by same pilot plant, the reactivity and the tolerance of microbial community for surrounding environment could be considerably changed by the operating method for the process.
