The education of arts has been known to have positive impacts on not only general public but also for groups that have low self-satisfaction or that feel a sense of alienation. For example, there are research reports that confirm that there was a change in the sense of accomplishment and self-effectiveness on the students in industrial high schools that have less self-assurance and faith in their own identities compared to the academic high schools after taking art classes. Also, it has been discovered in another study on juvenile delinquents that how they spend their leisure time affected the rate of second convictions. In addition, in the , it has been shown that the juveniles preferred the cartoon and animation field the most among different art fields. The purpose of this research is developing a learning-teaching curriculum that can be used in the youth detention center schools based on above research results. The goal of the arts education in the youth detention center must be in increasing the inner control factors such as self-esteem and self-confidence rather than raising professional technicians for employment. Therefore, the researcher will understand the environmental particulars of the youth detention center which is closed and in which group works take the most proportion to develop and propose a teaching-learning curriculum most appropriate for such environment to conduct cartoon and animation education.

The aim of this study is to characterize the optical properties of white light-emitting diodes lighting modules and then to evaluate the sensitivity of students and teachers in reacting to the optical properties of these modules. For the sake of this study, each of 5 lighting modules was introduced to the 5 test cabinets. The 5 test cabinets were evaluated and analyzed the student and teacher's sensitivity reaction. We have selected If questions on sensitivity of the lighting and evaluated these questions with semantic differential method. To verify the reliability and objectivity of the questions, the feasibility survey was carried out by a preliminary test. As a result of the test, the sensitivities on the test cabinets were classified the 4 factors, namely, activity as the first factor, stability as the second one , potency as the third one and sensitive image as the fourth one respectively. By the evaluation of student and teacher's sensitivity on the correlated color temperature, they preferred the cabinet with the higher color temperature in view of the activity and potency. And they preferred the cabinet with the lower color temperature in view of the stability factor. In the sensitive image, they preferred the 5800K, bluish white lighting regardless of the color temperature. By the evaluation on the color rendering index, they preferred the cabinet with the higher color rendering index in view of the activity, stability and sensitive image. In the potency factor, they preferred the white lighting with the middle color rendering index.

School violence is now considered not only as a problem for a victim and a offender themselves, but also as a social problem that requires responsibilities of school, home, society, and even nation. Crimes and risk factors are various inside and outside of school. In terms of solving those problems, this study examines the actual condition of school violence among students. In addition, it is considered what efforts are conducted by police to establish a safe school environment and the problems that derive from it. Futhermore, this study aims to discuss the ways of using the private security with regard to dealing with school violence. In this society, the expectation of security service from the police is increased as time passed. However, police has limited resources, thus it is beyond their practice. Policing has changed from being monopolized by government to cooperating with various security agents. Community is not considered as the subject for enforcing the law anymore, but as the cooperator for effective policing. With regard to the limitation of police force, using the private security is an effective alternative. Therefore, it is required that private security should be assigned legal authority and shared information with schools in order to patrol the blind spot. Finally, school violence prevention efforts should be conducted by applying physical and electronic security.

The purpose of this study was to investigate gender-specific changes of plasma MDA, SOD, and lymphocyte DNA damage during high intensity exercise. In this study, 17 healthy male and 18 healthy female college students ran on a treadmill at 85%$VO_{2max}$ until the point of all-out. Blood-collecting was carried out five times (Rest, Ex-Exha, R0.5h, R4h and R24h), and with the collected blood, plasma malondialdehyde (MDA), superoxide dismutase (SOD), and lymphocyte DNA damage were analyzed. Plasma MDA and SOD concentration increased significantly at the Ex-Exha (p<0.05), and there were no significant differences in gender. For the degree of lymphocyte DNA damage, all %DNA in the tail, tail length and tail moment increased significantly at the Ex-Exha (p<0.05), and %DNA in the tail and tail length were significantly higher in the male group than in the female group (p<0.05). These results suggest that acute high intensity exercise not only causes oxidative stress but also brings about lymphocyte DNA damage. In addition, it was found that males showed higher DNA damage than females in terms of oxidative stress subject to high intensity exercise. Nevertheless, further subsequent studies are required in order to better understand the mechanism behind DNA damage varying with gender, in a way that takes into consideration physical fitness, hormonal level, exercise intensity and duration - additional factors which might affect DNA damage.

This is to establish a model of the standardization of shelving, chairs, tables and card cabinets for college and university libraries in Korea. The size of furniture was measured on the base of the analysis of the human factors, such as the standard size of human bodies of the college students in Korea, the scope of work area, the moving degree of muscles, the limit of the visual field, etc. The results of this study are as follows: 1. It is desirable that the standard shelf length should be 800mm. and the maximum . shelving height should not exceed 1,803mm. And it is desirable that the bottom shelf has a ground clearance of about $210\~390mm$. 2. It is advisable that the sloped shelving has the slope from about 1,000mm, or 930mm, and the gradient should be $19^{\circ}$ from the above mentioned sloping position and the bottom of each shelf. And it is desirable that the slope height of each shelf should be 77mm. 3. It is advisable that the seat area for users should be $410\~420\times420mm$, and the seat height should be $390\~0400mm$. 4. It is desirable that the table size per user should exceed $490\times880\~890mm$, and the table height should be $680\~690mm$. 5. It is advisable that each tray of the card cabinet should hold about 740 cards, and the depth should exceed 430mm. And it is desirable that the maximum height of card cabinets should be as follows: 60du(drawer units)-$1,400\~1,460mm$, 30du-1, 300mm, 15du-1,100mm. In addition, it is advisable that the 30du cabinet should accomodate 5 trays vertically and 6 trays horizontally for avoiding the worst working position rather than 6 trays vertically and 5 trays horizontally. 6. It is desirable that the height of sliding reference shelves in card cabinets, or consultation tables should be 900mm. But in the case of the sliding shelves, it is desirable to be as follows: 15du-900mm when the card cabinet height is more than 1,100, mm, but unnecessary when less than 1,100mm high, 30du-1,000mm, or 1,100mm in the case of $5\times6du$, but 900mm in the case of $6\times5du$, $60du-900\~950mm$ when the card cabinet height is $1,400\~1,460mm$.

Urinalysis is considered to be easier and simpler than other tests. It has been known to cause no burden to patients, while offering important information on diagnosing, treating, and determining the prognoses of kidney and urinary tract diseases. Urinary sediments are usually performed by microscopic examination of centrifuged urine by technologist. The guidelines proposed by the Korean Association of External Quality Assessment Service are actually different from those actually practiced by medical institutions and taught to biomedical students in textbooks. Therefore, we verified whether different sediment preparation methods lead different test results. Specimens that tested positive from the occult blood and leukocyte esterase in the urine dipstick test were randomly selected for a microscopic examination. The differences in the urine sediment preparation affected the sediment concentrations, which influenced the cell grade and cell number per HPF. The first factor in determining the sediment concentration is the centrifugal force. Many medical institutions use 1,500 rpm as the centrifugal speed without considering the radius of the centrifuge; such a value may not be accurate for 400 G. Consequently, there were differences in urine concentrations, which influenced the results. The second factor is the amount of sediment in urine. Different amounts of the remaining supernatant led to different sediment concentration factors, again, causing different results. Furthermore, not only by using a pipette to obtain an accurate amount as stipulated, but also by roughly obtaining a drop, the microscopic examination using such a volume of sediment examined affected the results. Therefore, this study highlights the importance of standardization of urine sediment preparation procedures to promote consistency and accuracy across institutions.

The purpose of this study was to examine the Structural Equation Model (SEM) of scientific problem finding ability based on science related attitude, motivation and self-regulation learning strategy of the gifted in science. A total of 153 scientifically gifted students were selected from a university-based Sifted education center The instruments used for the study were Test of Science-Related Attitudes, Motivated Strategies for Learning Questionnaire (MSLQ), and Science Problem Finding Test. In order to examine Structural Equation Model (SEM) of scientific problem finding ability, we assumed scientific problem finding model related to science inquiry, model I (domain specific), and scientific problem finding model related to creativity, model II (domain general) The results of this research are as follows. First, the correlations between science related attitudes and MSLQ were significant; motivation and self-regulated learning strategy as sub factors were positively correlated to science related attitudes. Only scientific attitude as a sub factor of science related attitudes was significantly correlated to elaboration of creativity category in scientific problem finding ability. In other hand, self-regulated learning strategy was significantly correlated to elaboration, inquiry motivation and inquiry level in scientific problem finding ability. Second, as the results of SEM analysis, we confirmed model I and model II were the best adequate through the indices of best fit (TLI, CFI>.90, RMSEA<.08); scientific problem finding ability was directly influenced motivation and self-regulated learning strategy but science related attitudes indirectly influenced scientific problem finding ability through motivation and self-regulated learning strategy. Based on the results, the implications for science gifted education were discussed.

The working concept of the disadvantaged gifted is meant by those who hardly can have a chance to develop one's own gifts because of the environmental conditions and factors. The main purpose of this study is to explore the inherent trait of the music giftedness, which is composed of musical ability, creativity, and task commitment. Grounded upon the phenomenal research, this study purposefully samples ten disadvantaged students who participated in the arts gifted camp hosted by Korean National Research Institute for the Gifted in Arts. Thus, it explores the inherent traits of the disadvantaged gifted by coding, segmenting, and analyzing the interview with ten disadvantaged, and the evaluation reports of the expert group. The inherent trait of music giftedness of the disadvantaged gifted is shown as this: the inherent trait of the disadvantaged gifted in music is closely interrelated with one's own concept of giftedness. Whereas they show the high motivation and task commitment, they are hardly observed to have the creativity in their musical activities and learning. Finally, this study give a proposition for the strategy to stimulate and improve the inherent trait of the disadvantaged gifted in music: the importance of parents education and parent screening, meta-cognitive skills, the leaning-based creativity education, and the significant role of intrapersonal catalyst.

This study compared intake of vitamins and antioxidant nutritional status of smokers and nonsmokers, and the effect of supplementation of vitamin C and vitamin E on antioxidant system of smokers and nonsmokers. Subjects were 30 smokers and 30 non-smokers of male university students. They were divided into groups of 10 subjects each one with supplementation for 4 weeks, to investigate the effects of supplementation. Smokers were divided into vitamin C supplement group, vitamin E supplement group and vitamin C and vitamin E combination supplement group, and so were nonsmokers. The supplementation of vitamin C was 500mg and vitamin E was 400IU. There was no significant difference of antioxidant vitamin intakes between smokers and non-smokers, and plasma concentration of vitamin C in smokers was lower than non-smokers (p<0.05). Blood pressure was higher in smokers (p<0.05), with no difference in blood glucose levels, methemoglobin and TBARS, but SOD activity was significantly higher in non-smokers (p<0.001). Vitamin C supplementation resulted in a significant decrease of diastolic blood pressure (p<0.01), systolic blood pressure (p<0.001) and methemoglobin (p<0.001) in smokers. Also a significant decrease of diastolic blood pressure (p<0.05), systolic blood pressure (p<0.05), blood glucose (p<0.05), methemoglobin (p<0.001) and TBARS (p<0.05), with significant increase of SOD activity (p<0.001) were found in vitamin E supplement group. In vitamin C and vitamin E combination supplement group, there was a significant decrease of diastolic blood pressure (p<0.05), methemoglobin (p<0.01) and TBARS (p<0.05). In non-smokers, methemoglobins (p<0.001) of vitamin C supplement group and vitamin E supplement group decreased, and diastolic pressure (p<0.05), methemoglobin (p<0.01) and TBARS (p<0.05) significantly decreased in vitamin C and vitamin E combination supplement group. These results indicated better efficacy of antioxidant supplementation in smokers than in nonsmokers, suggesting that the supplementation of vitamin C and vitamin E might decrease the oxidative stress and various risk factors of smoking-related diseases.

Recently, according to increase in production of pond snails resulting from the widespread organic farming, organic farmers are showing a lot of interests in the promotion of consumption and extending the market of pond snails. This study was performed to suggest the process of product development of the ready-to-eat pond-snail Mandu as a health food, to show the results of market test of the pilot product, and to investigate the change of the sensory characteristics during storage periods. For the market test of pond-snail Mandu, the survey was developed and delivered to consumers. The questionnaire consisted of 3 parts such as respondents demographic characteristics, customer's perception of pond-snail Mandu before tasting, and customer's perception of that after tasting. And the market test was carried out with university students, welfare institution residents and apartment residents in the Seoul and Gyeonggi areas. As a result of the test, the most important purchasing factors were determined in the order of taste (49.5%), hygienic quality (12.5%), nutritional value (10%) and price (9%). And only 4.2% of respondents selected brand name as an important purchasing factor. After tasting pond-snail Mandu, consumers had suggested the better taste (t=6.986, p<0.000) and price (t=2.082, p<0.05) than those of before tasting. In response to favorable impression of pond-snail Mandu, 54.5% of total respondents evaluated positively. The favorable impressions came from iron-rich Mandu (27.6%), high protein and nutritious Mandu (24.4%), calcium-rich Mandu (17.9%), diet Mandu (13.3%), and delicious Mandu (12.5%) respectively. Sensory characteristics of pond-snail Mandu were evaluated by professional panels in terms of the softness of Mandu skin, chewiness, moistness, toothpacking, color, aroma, saltiness, and degree of plain, taste, and aftertaste. The evaluation of sensory characteristics on a 7-point scale, showed that softness of mandu skin (4.44) and aftertaste (4.11) got a low scores. The statistical difference of the tastes (p>0.05) was not founded by storage period of 7, 14, 21 and 28 days. Based on the result, the improvement of these characteristics are desired in developing the pond-snail Mandu. Research method applied to this study can be useful for developing a new product.
