Objectives: The purpose of the study was to examine the influencing factors of oral health-related quality of life in adults. Methods: A self-reported questionnaire was completed by 300 adults in Seoul and Gyeonggido from June to July, 2015 by convenience sampling method. Except 19 incomplete answers, 281 data were analyzed by t test, one way ANOVA, Pearson's correlation coefficient analysis, and multiple linear regression analysis using SPSS 18.0 program. The questionnaire consisted of general characteristics of the subjects, health-related characteristics, whole body dry symptoms and subjective perception of dry mouth. The oral health-related quality of life was measured by Likert five points scale, and a higher score indicated a lower quality of life. Results: The oral health-related quality of life in adult varied by age, systemic diseases, oral health status, missing tooth, stress, decayed tooth, gingival disease. The oral health-related quality of life had positive correlations with the subjective perception of dry mouth and whole body dry symptoms. The subjective perception of dry mouth(${\beta}$=0.245) had the influence on the oral health-related quality of life, oral health status(${\beta}$=-0.209), gingival disease(${\beta}$=-0.151), and decayed tooth(${\beta}$=-0.146) in order. Conclusions: The oral health-related quality of life was closely related to the subjective perception of dry mouth and the oral health status. It is necessary to develop the quality of life improvement programs including oral health prevention and care program in the adults.

Urticaria is a common dermatopathy, coming under "eun-jin(隱疹) in Korean Oriental medicine. We researched sixty-two patients of urticaria who had visited the Dept of Dermatology Oriental medical hospital Dongeui universty from January 2002 to April 2004 and had taken the Oriental herb medicine as Sungmagalguntanggamibang (SGT, 升摩葛根湯加味方) for verification of voluntariness of Korean Oriental medical treatment. In our time, urticaria is tending upwards, consequently the air pollution by industrialization, patronizing of convenience food by simplification of dietary life, stress and an abuse of medicine. Especially in case of chronic urticaria we're under going hardships in elimination of it's symptoms, because it's prognosis is inferior. We inspect the effects of SGT from various viewpoints and meet with following results. Results: 1. AS amount of taking the SGT increase, the effect in taking SGT period and the condition of present time become more satisfactory. 2. As continuous Time of urticaria decrease, the effect in taking SGT period become more satisfactory. 3. Etiology of urticaria is classified into the deficiency both of qi-blood(氣血兩虛), the moisture-heat of spleen-stomach(脾胃濕熱), the heat of blood(血熱), The wind-cold(風寒), The wind-heat(風熱), spleen-stomach accumulated heat(腸胃實熱) ect. The SGT is available in this order. 4. The effect in taking SGT period connects the quality of life of after treatment and the quality of life of after treatment is improved comparing with that of before treatment. The above results demonstrate that SGT effectively suppresses recurrent, pruitus and erythematous urticaria.

Objectives : Childhood is a critical period involving various developmental tasks that need to be accomplished. Childhood depression has overall negative implications for certain areas of development, including cognition, emotion, social skills, academic achievement, and ability to cope with stress. Yet, because depression can be "masked" by accompanying behavioral problems, early detection and diagnosis of childhood depression is somewhat challenging. In this study, using the Korean version of the Child Behavior Checklist (K-CBCL), we evaluated the association between children's self reports on depression and parents' assessment of children's behaviors. Methods : Subjects were recruited from the S city, a cohort comprising a non-random convenience sample of 226, 10-year-old ethnic Koreans in their fourth year of elementary school and their parents. All participants underwent several tests, including Children's Depression Inventory (CDI) and K-CBCL. Results : A total of 226 children, including 166 boys (73.5%) and 60 girls (26.5%), participated in the study. The average CDI for the participants was 14.57 (SD=7.54). Two items on the K-CBCL, total scale of adjustment scale and social withdrawal problems, showed a close association with the CDI. Conclusion : Although much remains to be elucidated, after controlling for covariates, the results of this study suggested that behavioral problems observed in children may be closely associated with depression.

This study was carried out to describe and analyze experimental studies conducted in graduates nursing degree. Of 170 experimental studies conducted during the past three decades between 1962 and August 1991, 150 studies were available, including 124 master’s and 26 doctoral theses. This study examined their general characteristics and detailed research methods using percentiles. The results were as follows 1. Most of the studies adopted a quasi-experimental design. 2. The subjects of the studies were chosen by convenience sampling except for two studies whose subjects were drawn by randomization. Studies comparing experimental and control groups were in the highest proportion and the most frequent sample sizes of each group were 21 to 30 for both experimental and control groups. 3. As to measurement, physiological measures were most frequent followed by psychsociological measures and active report questionnaires. Each study, on average, adopted two kind of measurement tools. Studies in which the data collection period was of 1~2 months were in the highest pro-portion. 4. All doctoral theses and 67.0% of master’s theses examined specific research hypotheses. Of these studies, the results of 92.5% supported the hypotheses. 5. Parametric statistics were the major analytical methods. In particular, t-test was used most frequently followed by Chi square, F-test, and Pearson Correlation Coefficients. 6. Patients were the most frequent study subjects. Frequent nursing interventions were information and education followed by support, distraction, and nursing treatments. 7. With regards to the dependent variables, “feelings” such as anxiety, pain, and depression were most frequent. In addition “exchanging” such as restoring, metabolism, cardiopulmonary function, infection and vital signs were adopted as the dependent variables in 29.1％ of the studies examined, while 12.3% of the studies selected “choosing” such as stress, health behavior, or role performance.

Background and purpose : Drug abuse is one of the most serious problems among the Korean adolescents today and has been associated with delinquent behavior in adolescents. The number of adolescents who abuse drugs is increasing yearly. Solutions to the problem, however, have not been well developed. The purpose of this study was to determine the effectiveness of a drug use prevention program which was developed by researchers. The program was a modified DARE(Drug Abuse Resistance Education) program for Korean adolescents. Methods: This study used an experimental, one-group pretest-posttest design with a convenience sample of 122 middle school students who were at one middle school located in Seoul. Data were collected using a self-administered questionnaire where ‘knowledge and attitude about drug use’, ‘social skill’, and ‘self-esteem’ were measured. The program had 12 sessions to improve knowledge and attitudes towards drugs, decision making skills, social resistance skills, management of stress and self-esteem of students. Teaching strategies for each session were varied lectures, group discussion. role-playing, question-and-answer sessions and audiovisual materials. Paired t-test was used to analyze the differences between the pre- and post-test scores on knowledge of and attitudes towards drug use, social skills, and self-esteem. Results : There were significant differences in knowledge and attitudes about drug use between pretest and post-test (p＜.05), but no significant differences in social skill and self-esteem(p＞.05). Conclusion: Our results showed that the drug use prevention program was not effective in promoting social-skill and self-esteem of Korean adolescents. These findings might be due to the respondents being in the period of early adolescence (puberty) and not being good at group discussion. So, further study is needed to develop a drug use prevention program appropriate to students 9 and 10 years old, and to encourge small group discussion.

This study was to explore demographic, psycho-social and clinical characteristics and the influencing factors on alcohol use of person with severe mental illness in the community. Cross-sectional descriptive design was used to recruit a convenience sample of 176 participants from four community mental health centers in Korea. The collected data were analyzed using t-tests, $x^2$-test, and logistic regression. Depending on the alcohol use (AUDIT-K), participants were divided into the problem alcohol use group (n=54, 30.7%) and normal group (n=122, 69.3%). The problem alcohol use group was significantly more smoking, anxiety, stress, suicidal thought, and had a lower age of onset, phase of rehabilitation, self-efficacy, and others' support. In logistic regression analysis, factors influencing on alcohol use were smoking, age of onset, phase of rehabilitation and others' support. The findings may provide useful information to develop strategies for prevent from alcohol induced the problems in this populations.

In this study the mechanical performance of the new wave dissipating block is evaluated through experiment and numerical analysis. Also, by selecting adequate reinforcement, the improvement of the structural performance is examined. The reinforcement is designed by predicting the amount of tensile force and the location where the tensile stress develops in the new wave dissipating block through numerical analysis. The new wave dissipating block is reinforced with the ordinary steel bars and the fiber reinforced plastic(FRP) bars which have advantages in ocean environment in terms of corrosion and fatigue. The test result shows that the fracture resistance of the un-reinforced concrete block is 350 kN which is about 6.2 times that of the weight of the block. All the test blocks which are reinforced by either steel of FRP bars show strength capacity of over 900 kN which is the maximum load of the test equipment. Although the single reinforcement with larger-diameter bars has advantage in terms of construction convenience, it is recommended to use multiple number of smaller-diameter bars in order to reduce the crack width.

Purpose: In recent years, the problem of runaway youths, which is rapidly increasing and worsening in nature, has emerged as a serious problem to individuals, home and the society as a whole. Against this back drop, this study was designed to illuminate the danger signals through extensive analysis of factors influencing the running away of middle-school students and, on this basis, build a forecast model on runaway middle-school students. Method: The subjects of this descriptive survey on the causal relation were 592 subjects enrolled in middle schools selected through convenience sampling. The data collected from June 19 to July 19, 2003 were analysed through the SPSS 10.0 program. The differences between the runaway group and the non-runaway group were determined through chi-square and t-test. Also logistic regression analysis was conducted on the basis of the purposeful selection method for constructing the forecast model. Result: The findings are as follows: Individual-related factors predicting runaway middle-school students were smoking experience, delinquent experience, psychosomatic symptoms and stress. A home-related factor was attachment to family. A society-related factor was the number of delinquency friends. Conclusion: The findings of this study suggest that a broad intervention program should be provided to middle-school students' culture related to runaway group. It is also recommended that a variety of individual, home and society-related programs should be developed for the runaway group.

Nowadays, there are many attempts to develop domestic medical-equipments. In this study, it is performed to developed a new vertebral fusion device. The basic models are a rectangular-frame type and a screw type which are generally used for the patients. The main purpose of the development of a new device is to reduce the amount of bone taken out for the insertion of a device to vertebral disc and this paper is focused on th concept of a new device shape. In the results, two types are devised. One is a folding type and the other is a separate-push-in type device both are in primitive stage. However, in a folding type there are mechanical pins and the analysis of pins and the lock system is still in study and needs some time. Therefore a separate-push-in type is introduced in this study mainly and a prototype and 3-D finite element model are made and experimented and stress analyzed. From the results it is considered that it is stable for the basic loading condition of vertebra, however, it is required to develop a supporting operational equipment for the convenience of the operation in practice.
