This study identifies the factor structure of sociocultural attitudes toward appearance, appearance management attitudes, fashion behaviors, and the effects of sociocultural attitudes toward appearance and appearance management attitudes on fashion behaviors. Questionnaires were administered to 255 college students living in Daegu Metropolitan City and Kyungbook province. The data collected were analyzed using frequency, factor analysis, multiple regression, and t-test. The findings were as follows. Sociocultural attitudes toward appearance were composed of two factors (body internalization and appearance recognition). Appearance management attitudes were composed of four factors (shape management recognition, weight management, appearance satisfaction, and health care). Fashion behaviors were composed of six factors (convenience, fashion following, self-satisfaction, attractiveness, pursuit of change, and pleasure). Gender of college students showed a distinction between the sub-variables of sociocultural attitudes toward appearance factors (body internalization) and appearance management attitudes (weight management) and fashion behaviors (convenience, fashion following, self-satisfaction, and pleasure). Women had more desire to have a similar looking body of TV celebrities than men. The effects of sociocultural attitudes toward appearance and appearance management attitudes on each fashion behavior variables (convenience, fashion following, self-satisfaction, attractiveness, pursuit of change, and pleasure) were explained by the factors of body internalization and appearance recognition, and weight management, appearance satisfaction, and health care. College students produced fashion appropriate to the situation. Strategies of fashion marketing based on these results are as follow. Through mass media, advertisers help university students realize a healthy outlook and create a social atmosphere that can promote healthy body attractions.

This study is to seek methods for optimum management of foodservice system for elementary schools in Korea through surveying and analyzing the current status of the "common-management foodservice system" and certain important factors relating to its operations. For the survey of the current status of the "common-management foodservice system", questionnaires are prepared as against schools adopting "common-management system"("Common Schools") as well as schools adopting "conventional management system" ("Conventional Schools") in Kyungsangbookdo ("Kyungbook") area. The survey items are composed of general items, items concerning tasks of dietitians, items concerning purchasing activities and items concerning level of recognition and job-satisfaction of the dietitians. Total 46 dietitians from Common Schools and 65 dietitians from Conventional Schools in Kyungbook region responded the questionnaires. The results of this study are as follows: 1. Information Concerning Dietitians Average age of the dietitians: 26.6 yrs Ratio of two years or less of experiences as school dietitian: Dietitians from Common Schools: 59.1％ Dietitians from Conventional Schools: 50.8％ 2. Types of the Foodservice In both schools, rural type are prevalent; however, between urban types and islands types, the ratio of urban types are larger than the ratio of islands types in Conventional Schools, and the opposite is true in Common Schools. 3. Decision of Suppliers The ratio of dietitian＇s participaion in the decision making reaches only 38.3％, indicating the possibility of problems in quality control and hygienic aspects of the food supply. 4. Factor Analysis of the Foodservice Duties Food supply and general affairs administration work was carried out very well (4.2), while personnel management and operational improvement work (2.8), nutritional education work (2.3), and information related work were poorly carried out. No significant differences were found between the two types of the foodservice management systems. 5. Job Satisfaction scores of Dietitians Dietitians were more satisfied with the works (50.0), supervision (50.5) and co-workers (46.9) than pay (18.0) and promotion (22.3).

The dissociation constants of ${\beta}$-alanine and ${\gamma}$-aminobutyric acid were measured in the temperature range from 20 to $40^{\circ}C$ and pressure up to 2,500 bar by conductometric method. The both dissociation constants of respective amino acid increase with temperature increase but pressure effect is not same as the temperature. The $K_1$ increases as pressure increases but $K_2$ decreases. The properties of these amino acids were discussed in terms of the thermodynamic properties of the dissociation reaction. A relationship between the dissociation constants and the distance between substituted groups of amino acid was discussed. The substituted effects of the reaction were deduced from Hammett reaction and substituted constants which were calculated from the measured dissociation constants.

The purpose of this study is to classify the appearance concern into groups and analyze the differences of the attitude toward plastic surgery and clothing behavior by groups. Questionnaires are administered to 206 female adults in their 20's-50's living in Deagu and Kyungbook areas from $10^{th}$ July to $19^{th}$ July, 2013. Frequency, factor analysis, reliability analysis, correlation analysis, cluster analysis, ANOVA, Duncan-test and ${\chi}^2$-test were used for data analysis. The appearance concern is categorized as follows: appearance harmony focus and body focus. The attitude toward plastic surgery was found as risk tolerance, image improvement/surgery desire and keeping the secret of surgery. Clothing behaviors are found as individuality focus, other focus, convenience and luxury ostentation. The appearance concern shows a significant correlation with the sub-variable attitude toward plastic surgery and clothing behavior. One test in the groups is determined by demographic variables like occupancy and monthly income. Appearance concerns are classified into three groups as follows: appearance concern group, low appearance concern group and body concern group. The groups show a significant difference in the attitude toward plastic surgery and clothing behavior. This difference indicates that the 20's show a high body focus on their appearance concern, an attitude of image improvement/surgery desire toward plastic surgery and another individuality focus on clothing behavior while 50's care more about convenience in their clothing behavior.

Trauma to the primary teeth may have an effect on the successive permanent teeth. Thus, the treatment plans should be focused on safety of their permanent teeth. The degree of developmental disturbances in those permanent teeth depends upon many factors including the age of the children, developmental conditions of the affected teeth, types and severities of trauma and time interval from the moment of trauma to the initial treatment the patients received. The complications of the effected permanent teeth vary from the mild enamel hypoplasia to the premature finishing of teeth development. In this study, children whose ages were 33 months, 5 years, and 26 months presented the developmental disturbances to their permanent teeth, which resulted from the trauma to the primary teeth: the intrusion, the avulsion, and the subluxation. There showed a mild complication in the case of subluxation resulting in enamel hypoplasia, but, the more severe complication of the root dilacerations occurred in the case of intrusion. Furthermore, the 5-year-old patient whose primary dentition was near in transition period to the permanent one, the more complicated problem such as stop of root development of the permanent teeth was resulted from the avulsion. Thus, one should assume that the types of trauma and the age of the children at the moment of trauma have different effects on those successive permanent teeth. In conclusion, when the trauma that causes changes in the position of primary teeth happened, it is important to arrange an appropriate treatment procedure considering the types of trauma and the developmental conditions of the permanent teeth.

Trauma commonly leads to ankylosis for the tooth whose periodontal ligaments have been injured. In growing patients, an ankylosed tooth can disrupt alveolar development, resulting in infraocclusion of the affected tooth. Consequently, this causes aesthetic problems during adolescence, interferes with prosthetic treatment due to the inclination of adjacent teeth, and complicates orthodontic dental movement. When the infraoccluded ankylosed tooth is extracted, a considerable amount of alveolar bone is lost, especially in the maxillary anterior region. Moreover, depression of the thin buccal alveolar bone compromises aesthetic restoration. In order to prevent alveolar bone loss, the ankylosed tooth should be treated by decoronation. In the present study, the traumatically injured maxillary incisors of 9-year-old and 10-year-old patients that present infraocclusion accompanied by ankylosis were treated with decoronation procedures. Decoronation procedures were performed when the affected teeth were 2-3 mm below relatively to the adjacent teeth. Moreover, the patients were treated before they get to 16 years old considering the maximum growth peak of the korean adolescents. As the results, there are favorable clinical results associated not only with preservation of horizontal alveolar volume but also with increase in vertical alveolar height after decoronation in growing individuals.

Gastrodia elata Blume (GEB) is a traditional herbal plant that has been used in Asian countries for centuries as an anticonvulsant analgesic, and a sedative for treating general paralysis, epilepsy, vertigo, and tetanus. This study was designed to optimize conditions for ethanol extracts or GEB by analyzing and monitoring the extraction characteristics with response surface methodology. The extract was used for analysis of the effective components of GEB. The estimated optimal conditions were 63.62% in ethanol of 5.06 mL/g in solvent per sample, and 6.25 hr in extract time. The optimal extraction conditions for $ \gamma-aminobutyric$ acid, were 45.52%, 5.67 mL/g, and 6.04 hr, while those for $\rho-hydroxybenzyl$ alcohol were 62.73%, 5.02 mL/g, and 5.95 hr. Regression equation was generated for each variables and then superimposed them, such as soluble solid, $ \gamma-aminobutyric$ acid and $\rho-hydroxybenzyl$ alcohol content thereby resulting in superimposed values of extinction conditions like $45\sim65%,\;5\sim7mL/g$ and $5\sim7$ hr, respectively.

In order to reduce the damage of effective component during processing, we carried out hot-water extraction monitering in Gastrodia elata Blume by response surface methodology. The extraction con야tions for vanillyl alcohol, vanillin and coumarin were optimized at 91.07, 93.73 and $96.30^{\circ}C$, for 2.64, 2.58 and 3.84 hr, at the concentration of 15.16, 21.56 and 19.88 mL/g, respectively. The optimal condition for extraction of total phenolics was acheved at $98.14^{\circ}C$, 3.20 hr and 18.63 mL/g. This study elicited regression formula for each variable, and superimposed the total optimal conditions of extraction for effective compounds and optimal condition for antioxidant characteristics dividing processing factors. It is shown that the predicted result under the extraction condition as follows: extraction temperature for $90{\sim}100^{\circ}C$, extraction time for $3{\sim}4hr$, and solvent volume of $15{\sim}20mL/g$ of sample.

The Chunma (Gastrodia elata Blume) requires a simple pre-treatment, due to inconvenience or preservation, toxicities, and pungencies in intact state. Various drying conditions were examined to establish the physicochemical properties of Chunma by the response surface methodology (RSM). Weter activity and total phenolic acid contents of Chunma dried extracts were optimal at $79.56^{\circ}C$ and $79.64^{\circ}C$ for 7.17 hr and 8.74 hr, respectively, for their characteristics. Electron-donating ability and nitrite-scavenging activity were optimal at 79.79 and $7.99^{\circ}C$ for 8.57 and 8.07 hr. We generated a regression equation for each variable and then superimposed the optimal condition in acquiring values for each frying process factor, physicochemical properties, resulting in that the optimal drying condition was at $75{\sim}80^{\circ}C$ for $8{\sim}9 hr$.
