  • The main purpose of this study was to speculate how psychological state of adolescent students has changed their school uniform style. For the study, the distinctive characteristics during adolescence stage were theoretically examined. Through the examination, this study found four interests in fashions and school uniforms. For the purpose, this study conducted interviews with grade 2 students in a total of six coeducation secondary schools in Seoul, Gyeongki and Gwangju using a questionnaire. The survey period ranged from December 15 2008 to December 24 2008 and a total of 1196 were used for a final analysis. This study extracted factors as Principal Components Analysis and used Varimax for orthogonal rotation analysis. To measure confidence, it used Cronbach's a test to item internal consistency. For data analysis, it used SPSS WIN 12.0 and for hypothesis analysis, frequency analysis, cross analysis, independent t-test, and one-way ANOVA were conducted. For posterior analysis, it used Sheffe test. The results are as follows: First, the interests in fashion and school uniforms differed depending on their own tastes, but these interests were more influenced by environment around school. Secondly, the boy subjects were more aggressive towards repairs their uniforms than the girls, which suggested that boys had stronger desire to show themselves to others and more satisfaction from repairs their uniforms than the girls. Based on the results, this study concluded as follows: We should pay attention to preventing deformation in original design of school uniforms while expanding options to have variable designs or to change detailed part of design. So, there will be no additional uniform mending expense and financial loss to parents, and students will be more satisfied with their school uniforms.

  • The estimation of pile bearing capacity is important since the design details are determined from the result. There are numerous ways of determining the pile design load, but only few of them are chosen in the actual design. According to the recent investigation in Korea, the formulas proposed by Meyerhof based on the SPT N values are most frequently chosen in the design stage. In the study, various static and dynamic formulas have been used in predicting the allowable bearing capacity of a pile. Further, the reliability of these formulas has been verified by comparing the perdicted values with the static and dynamic load test measurements. Also, in most cases, these methods of pile bearing capacity determination do not take the time effect consideration, the actual allowable load as determined from pile load test indicates severe deviation from the design value. The principle results of this study are summarized as follows : As a result of estimate the reliability in criterion of the Davisson method, t was showed that Terzaghi & Peck >Chin>Meyerhof > Modified Meyerhof method was the most reliable method for the prediction of bearing capacity. Comparisons of the various pile-driving formulas showed that Modified Engineering News was the most reliable method. However, a significant error happened between dynamic bearing capacity equation was judged that uncertainty of hammer efficiency, characteristics of variable, time effect etc... was not considered. As a result of considering time effect increased skin friction capacity higher than end bearing capacity. It was found out that it would be possible to increase the skin friction capacity 1.99 times higher than a driving. As a result of considering 7 day's time effect, it was obtained that Engineering news, Modified Engineering News, Hiley, Danish, Gates, CAPWAP(CAse Pile Wave Analysis Program) analysis for relation, repectively, $Q_{u(Restrike)} / Q_{u(EOID)} = 0.98t_{0.1}$ , $0.98t_{0.1}$, $1.17t_{0.1}$, $0.88t_{0.1}$, $0.89t_{0.1}$, $0.97t_{0.1}$.

  • The purpose of this study is to develop HTE-STEAM program using natural disasters for high school students and to verify their attitude and satisfaction with STEAM. We developed the HTE-STEAM program utilizing natural disasters and tested the effectiveness of 243 students from G High School and N High School. For data analysis, a single group pretest and post response t-test were conducted to verify the effects on attitudes and satisfaction with STEAM. The research results are as follows. First, we developed STEAM education programs for high school students by selecting the topic of "natural disasters" in the area of earth science and flying drones as lifesaving drones. The six-hour program was designed to give students the experience to solve problems by applying essential knowledge related to natural disasters and drones, and what they learned in other situations. Second, there was a significant statistical test result in the t-test of the corresponding sample by the difference between the pre and post score of the STEAM attitude test (p <.05). The drone-based HTE-STEAM program had a significant improvement in the overall attitude toward STEAM education, which consists of seven subfactors. Third, in the HTE-STEAM satisfaction test, the average value of the lower job offer was 3.64 ~ 3.76, which showed a positive response overall. It is judged that the students' satisfaction is improved through the students' understanding of the problem situation and the design of creative convergence and production process.

  • A GEN TEST of the auxiliary power unit of a T-50 series aircraft is performed as part of the operational test of its emergency power system on the ground before flight. At this time, the auxiliary power unit should be automatically turned off via the response signal of the ECU when power is not normally supplied to the emergency power system. If the correct operation of the emergency power system cannot be confirmed on the ground, it is not possible to proceed with the flight. This kind of defect is a major factor causing the operation rate of the aircraft to be decreased. The defect code identified by the ECU was confirmed as a defect in the inverter. However, the same defect was found after replacing the inverter. This report presents an improved method of identifying the cause of the defect by analyzing the response characteristics of the ECU and emergency power system and allows the ECU to be recognized as the cause of the defect if the inverter does not generate a voltage within a certain time. Also, the application of the improved method confirmed that it can satisfy the output request time of the emergency power system and effectively prevent the auto-shutdown of the auxiliary power unit.

  • The aim of the present study was to evaluate the bioequivalence of two talniflumate preparations. We used Somalgen tablet (Kun Wha Pharmaceutical Co., Korea.) as a reference drug for bioequivalence of Crimain tablet (Samjini Pharmaceutical Ind. Co., Korea), and performed this whole study according to the guidelines of Korea Food and Drug Administration (KFDA). Twenty four healthy male volunteers, $22.8{\pm}2.2$ years in age and $64.6{\pm}5.3\;kg$ in body weight, were divided into two groups and a randomized $2{\times}2$ cross-over study was employed. After one tablet containing 370 mg of talniflumate was orally administered, blood was taken at predetermined time intervals and the concentrations of talniflumate in plasma were determined using HPLC method with UV-detector. The analysis system was validated in specificity, accuracy, precision and linearity. These items of the analysis condition in this study conform to the guideline of KFDA. The pharmacokinetic parameters such as $AUC_t\;and\;C_{max}$ were calculated using the analysis condition we established and ANOVA test was utilized for the statistical analysis of the parameters using logarithmically transformed $AUC_t$ and Cmax. $Mean{\pm}SD$ of reference drug and test drug in $AUC_t\;and\;C_{max}$ value were $1.27{\pm}0.58\;({\mu}g/ml{\cdot}hr)\;and\;0.27{\pm}0.13\;({\mu}g/ml)$ and $1.14{\pm}0.46\;({\mu}g/ml{\cdot}hr)\;and\;0.26{\pm}0.10\;({\mu}g/ml)$ respectively. The 90% confidence intervals using logarithmically transformed data were within the acceptance range of log(0.8) to log (1.25) for $AUC_t\;and\;C_{max}$, respectively. These results indicate that Samjin talniflumate tablet is bioequivalent to reference drug, Somalgen tablet.

  • Purpose: This study analyze the correlation between elections and wild Fire to provide information necessary for formulating wild fire prevention and response policies. Method: Data of the Forest Service and the Meteorological Administration were used to compare the occurrence and burned area of wild fires in election and non-election years. Statistical significance between the two groups was analyzed with an independent sample t-test, and MANOVA(multivariate analysis of variance) was used to evaluate the effects of temperature and humidity. Result: There was no statistical significance in the occurrence and burn area of wild fires between election and non-election years. However, analysis of the raw data indicated significantly greater damage in election years. MANOVA revealed that election status, temperature, and humidity did not significantly impact the occurrence and burn area of large wild fires. Conclusion: Wild fire occurrence and burned area were higher election years than non-election years, possibly due to election-related social factors. Thus, enhancing wild fire prevention and response policies in election years and considering weather factors and social activites is necessary.
