The purpose of this study was to analyze the image, perception, and preference type of high school students of Hanbok and examine the differences according to gender and participation in Hanbok classes. For this purpose, a survey was conducted with 438 high school students in Busan. Frequency analysis, chi-square test, t-test, and F-test were performed using the SPSS and the results were as follows. Firstly, for most high school students, Hanbok has an elegant image, but it was also confirmed that they perceive Hanbok to have a splendid image due to its exposure in mass media and SNS. The image of Hanbok differed by gender and participation in Hanbok classes. A higher percentage of male students than female students perceived Hanbok to have rustic image. Secondly, the type of hanbok that high school students prefer was traditional Hanbok, followed by fusion Hanbok, casual Hanbok, and fashion Hanbok. Hanbok preference type differed by gender and participation in classes. Group participating in hanbok classes showed a higher preference for fashion Hanbok than those who did not. Thirdly, high school students' perception of traditional Hanbok was above average. By subcomponents, it was shown in the order of 'esthetics', 'sustainability', and 'practicality'. It was found that there were statistically significant differences in traditional Hanbok perception according to gender and participation in Hanbok classes. Female students evaluated more positively for traditional Hanbok than male students and students who participate in Hanbok classes evaluated traditional Hanbok more positively than non-participating students.

An interest in 'ordinary things' has been increased because public things become issues as the influence of mass media including mass production has been increased in the 1950s. And this phenomenon drew an art style of pop art in the world of art. Media art means that the fine arts are expressed by means of media such as TV and monitors because media has been developed in the modern society. It started emerging through the artists such as Nam June Paik, Bill Viola, and others in the 1960s. Recently, it can be easily accessible not only at the art museum but also in everyday life such as cafe, park, fashion show, performance, and etc. This study analyzed that how many different techniques of pop art were borrowed by especially Nam June Paik media art and how they influenced it. Accordingly, this study respectively analyzed expressive techniques and characteristics of both pop art and Nam June Paik's media art and then searched for their similarities based on the analysis. Both Nam June Paik's media art and pop art extended media by using various ordinary things in everyday life neglected previously as a material. Next, the characteristic of pop art shown in Nam June Paik's media art is participation with audience. While the arts in the past were high-level culture that only certain people could understand and enjoy, pop art or Nam June Paik's media art is an art trend that has led the popularity of fine arts and audience participation in order to let diverse classes enjoy without any specific knowledge.

In general, quantitative chemical analysis in various areas including food, the environment, in vitro diagnostics, etc., requires traceability in order to increase the reliability of the measurements. Measurement traceability is a property of an unbroken chain of comparisons relating an instrument's measurements to SI units. Purity analysis is the first process for establishing traceability to SI units in chemical measurements. The purpose of this study is to develop and validate a method of purity assignment for establishing the traceability of $17{\beta}$-estradiol measurements in an in vitro diagnostics field. The establishment of this method is very important as it can be applied to the development of CRM and to the analysis of the purity of other hormones. The method of assignment of the purity of $17{\beta}$-estradiol was developed using the mass balance method and was validated through participation in an International comparison. In the mass balance method, impurities are categorized into four classes as follows: total related structure impurities, water, residual organic solvents, and nonvolatiles/inorganics. In this study, total related structure impurities were characterized by a gas chromatography-flame ionization detector (GC-FID) and a high-performance liquid chromatography-ultraviolet (HPLC-UV) detector, water content was determined by a Karl-Fisher coulometer, and total residual solvents and nonvolatiles/inorganics were checked simultaneously by thermogravimetric analysis (TGA). The purity of the $17{\beta}$-estradiol was 985.6 mg/g and the expanded uncertainty was 2.1 mg/g at 95% confidence. The developed method can be applied to the development of certified reference materials, which play a critical role in traceability.

The purpose of this research is to study characteristics of Korean adults in the cultural consumption in the first decade of the early 21st century based on . The whole course of the cultural consumption of Korean adult from 2000 to 2010 has been steadily on the upswing. For Korean adults, the first decade of the early 21st century is the time when mass culture had been generalized in their cultural consumption, regardless of any generations. Besides, the twenties have been proved to be the core generation of the cultural consumption in Korean society.

Liquid chromatography/mass spectrometry using isotope dilution method has been established as a primary method for the measurement of cortisol in human serum. Verification of this method was accomplished by the participation in Consultative Committee for Amount of Substance-Metrology in Chemistry (CCQM) pilot study. Two levels of cortisol certified reference materials were prepared and certified by the established method. They were used as sample materials for the proficiency testing. The expanded uncertainty in the measurement of cortisol in human serum was approximately 1.2% at 95% confidence level. The results of the proficiency testing showed a good precision among the participants, but some bias to the certified values. This means that commercial field laboratories should keep traceability chain to SI unit through available reference measurement procedures and/or available reference materials.

There are severl types of Eco-village developed in abvanced countries including urban, suburban and rural style. For the establishment of Eco-village in Korea, it was focussed to introduce the rural style which has been developed inyersively in European countries such as Denmark, England and Germany. As a key cencept for Eco-villge it was explained briefly and discussed on the renewable energy(wind power park, bio-mass and solar energy collector and heating system), eco-architure, methane gas device, living machine (wastewater treatment facility) and organic farming. It was also discussed how important the basic standard and guidelines for organic agriculture to run essential for the system. For this reason major principles of international applicable standard(draft) for organically grown foods by FAO/WHO Codex alimentarius was shortly desidered. as one of very suitable type for Environmental Agriculture Districts Program which Korean govenment is going to establish in the near future. In conculusion it was also suggested that positive participation of organic famers, enthusiastic eneagement of inhabitans and support strategy of govemment /NGO groups might play very important role for successful managment of Eco-village ecologically sustainable after establishment.

The mechanisms and metabolic products involved in the degradation of an organophosphate insecticide, diazinon, were studied in submerged paddy soil under the laboratory condition at $30^{\circ}C$. Diazinon abatement in non-sterilized soil was more rapid than indicating microbial participation in diazinon in soil. One-half of the original applications was lost in 2 days and less than 5% remained after 7 days. During the same period, dizinon applications increased tha microbial populations in accordance with the monooxygenase and esterase activities in soil. These results suggest that the microbiological factors develop in soil following diazinon application. The esterase and monooxygenase-catalyzing degradation products of diazinon were isolated and tentatively identified by mass spectrometryas 2-isopropyle-6-methyl-4-hydroxy pyrimidine, diazoxon, hydroxydiazinon, and sulfotep.

Purpose: The purpose of this study was to examine the effect of a walking program on body mass index (BMI), blood pressure, cholesterol, and blood glucose in community-dwelling older adults. Method: A quasi-experimental research design (one group pretest-posttest) was employed. Participants were recruited in Seoul and a total of 57 community-dwelling older adults completed the 10-week walking program. Descriptive statistics and paired t-tests were used in the data analysis by SPSS WIN 14.0. Result: The participants showed lower BMI, systolic blood pressure, diastolic blood pressure, cholesterol level, and blood glucose level after than before participation in the walking program. Body mass index significantly decreased (t= 2.911, p= .005) after completing the walking program. There were, however, no significant changes in blood pressure, cholesterol, and blood glucose after completing the walking program. Conclusion: Findings of this study indicated that the 10-week walking program had favorable effect on BMI. Future research needs to target various older adult groups during a long-term period.

The main focus of this study was to investigate effects of lumbar central posteroanterior (PA) mobilization on isometric knee extension (IKE) ability and patellar tendon reflex amplitude (PTRA) in healthy university students. University students aged 19-26 (male; 10, female; 10) without any neurological disorders participated voluntarily and excluded the subjects with abnormal reflexes. The participation had an average body mass of $64.25{\pm}13.52kg$, an average height of $1.66{\pm}0.08m$, and an average Body Mass Index (BMI) of $23.07{\pm}3.21$. Every student was randomly assigned to be received squatting exercise and PA mobilization sequentially with 5 days of wash out period. IKE and PTRA were not significantly different between the two groups after the intervention. All the outcome measures were arranged into two data groups; PA mobilization and squatting exercise data group. In the PA mobilization data group, IKE and PTRA significantly increased after the intervention, however, these aspects were decreased in the squatting exercise group. These findings suggest that IKE and PTRA increase immediately after PA mobilization, therefore PA mobilization could be a valuable topic for controlled clinical trials.
