This study was performed to evaluate soft tissue cephalometric norms for Korean adults which can be implemented in surgical orthodontic treatment planning using selected horizontal reference plane especially for Koreans (Male: $SN-7.5^{\circ}$, Female: $SN-9.0^{\circ}$) and a simplified analytical method. 70 males and 70 females consisting of freshmen of Yonsei University from 1996 to 1997 and students from the Dental College of Yonsei University were chosen according to clinical examination and cephalometric analysis. The samples had normal profiles, normal anteroposterior skeletal relationship(ANB angle of $0^{\circ}\;to\;4^{\circ}$ and Wits appraisal of -4.0mm to 0mm), and Class I molar and canine relationship. They had no missing or supernumerary teeth and had no experience of orthodontic or prosthetic treatment. After the selection of 15 soft tissue landmarks and the construction of horizontal and vertical reference lines, 25 measurements were taken. These consisted of vertical and horizontal linear measurements and angular measurements. The results were as follows. 1. Mean and standard deviation of the measurements were calculated in males and females. 2. Vertical measurements were comparably bigger in males than females whereas anterior facial height ratio(sN-Sn/Sn-sMe) and lower anterior facial height ratio(Sn-Stms/Stmi-sMe) showed no significant difference between sexes. 3. Most of the horizontal measurements in relation to the vertical reference line(G-perpendicular) showed no significant difference between sexes. 4. Nasofacial angle, columellar angle, nasolabial angle and facial contour angle showed no significant difference between sexes. 5. The upper and lower lip were positioned about $-1.0{\pm}2.0mm$ and $+1.0{\pm}2.0mm$ in relation to the Ricketts' esthetic line in both sexes. In this study, soft tissue cephalometric norms of Korean adults for orthognathic surgery were obtained.

This study was performed to evaluate hard tissue cephalometric norms for Korean adults which can be implemented in surgical orthodontic treatment planning using selected horizontal reference plane especially for Koreans (Male: $SN-7.5^{\circ}$, Female: $SN-9.0^{\circ}$) and a simplified analytical method. 70 males and 70 females consisting of freshmen of Yonsei University from 1996 to 1997 and students from the Dental College of Yonsei University were chosen according to clinical examination and cephalometric analysis. The samples had normal profiles, normal anteroposterior skeletal relationship(ANB angle of $0^{\circ}$ to $4^{\circ}$ and Wits appraisal of -4.0mm to 0mm), and Class I molar and canine relationship. They had no missing or supernumerary teeth and had no experience of orthodontic or prosthetic treatment. After the selection of 23 landmarks and the construction of horizontal and vertical reference lines, 22 skeletal and 12 dental measurements were taken. These consisted of vertical and horizontal linear measurements and angular measurements. The results were as follows. 1. Mean and standard deviation of the measurements were calculated for males and females. 2. Most of the skeletal vertical measurements, and maxillary and mandibular length were bigger in males than females. Whereas anterior facial height ratio(N-ANS/ANS-Me) as well as maxillary and mandibular antero-posterior position in relation to the vertical reference line(N-perpendicular) showed no signigicant difference between sexes. 3. Maxillary and mandibular dental antero-posterior position in relation to the vertical reference line(N-perpendicular) showed no significant difference between sexes. 4. The upper incisor show(U1-Stms) was $2.1{\pm}1.7mm$ in males and $3.3{\pm}1.7mm$ in females. In this study, hard tissue cephalometric norms of Korean adults for orthognathic surgery were obtained.

This study was to find out whether MBT shoes were more effective than general sporting shoes on the kinematic physiology. We comparatively analyzed energy consumption, heart rates, rating of perceived exertion, lactic acid density in blood and muscle activity with EMG. The subjects were 10 regular students of K Univ.(5 male and 5 female). They wore the general sporting shoes for stage 1(group 1), the MBT walking shoes for stage 2(group2) under the same conditions. There was one week interval between stages. 1. There was no significant difference in the energy consumption and the heart rates between two groups. Group 1 showed a higher energy consumption and heart rates than Group 2 under the speed of 4.0 mph. On the other hand, Group 2 showed higher ones over the speed of 4.0 mph. 2. There was no significant difference in the rating of perceived exertion and lactic acid density in blood between two groups. But Group 2 showed a lower fatigue strength than Group 1. 3. Group 2 showed a higher muscle activity with EMG than group 1, especially at the speed of 2.0, 2.5, 3.0, 3.5 mph in quadratus lumborum muscle and at 4.0mph in tibialis anterior muscle. In conclusion, we are less tired in MBT shoes than in general sporting shoes. Also, we can dorsiflex better in the ankle joint, straighten the lumbar region well and walk erect in MBT shoes. Specially, when it walks slowly, it is favorable in an erection walk and when it walks quickly, we have advantage of obesity management.

Objectives The purpose of this study is to get the basic information from patients how much they understood about their medication and also to know whether patients are making reasonable drug choice between Health Functional Foods and Herbal medicine. Methods 500 questionnaires were handed out to the parents of students in two elementary schools located in OO, Junlabukdo province. 421 questionnaires were completed to be evaluated. Results Among 421 subjects, 53.0% were female, and 47.0% were male. The percentages of the subjects consuming Health Functional Foods and herbal medicine were67.7% and 67.8%, respectively. Among those people who consumed Health Functional Food, 44.1% were using nutritional supplements, red ginseng or ginseng products (26.9%), chlorella products (11.5%), and plum extract products (7.7%). As for the reason to consume Health Functional Foods were varied, but 'in order to be healthy, although currently displaying no illness.'(43.0%) were the most responses among the given choices. On the other hand, the reason for consuming herbal medicine was 'In order to grow taller'(26.1%), 'In order to cure weak physical state frequently displaying common illnesses',(25.9%), and 'In order to cure diseases.'(23.3%). For the questions about effectiveness after consumption,the 69.9% subjects said that it seemed to be effected, and that % was slightly higher than that of subjects with consuming Health Functional Foods(64.4%). For question concerning preferences between Health Functional Foods and herbal medicine, 57.5% chose herbal medicine, and this percentage was higher than that of Health Functional Foods(42.5%).As for the reasons of additional consumption of the Health Functional Foods, subject answered as 'Easy to consume.'(41,6%), which was the most common among the subjects consuming Health Functional Foods. On other hand, the subjects of herbal medicine answered as that herbal medicine is 'more effective'(45.7%), and 'more trustworthy in preventing side-effects.'(40.3%). After consumption of the herbal medication, only 3.9% of the subjects consuming either Health Functional Foods or herbal medicine had side-effects. The most common side-effects were 'dermal reaction' which is normally caused by Health Functional Foods and 'indigestion' problems caused by herbal consumption. Conclusions According to the 421 subjects those involved in study, the percentages of consuming Health Functional Foods(67.7%) and herbal medicine(67.8%) were similar. The most commonly consumed products were a type of Health Functional Foods which were the nutrition-supplying products. Ginseng or red ginseng products were the next commonly used products. Health Functional Foods were commonly consumed for preventing illness and maintaining health rather than any other purpose. In contrary, herbal medicines were more commonly consumed for purposes such as for growth or treating certain type of disease. As a result of consumption, more than half of both subject replied as 'satisfied'. As for the side effects, dermal reaction was the most common problem for those with consuming Health Functional Foods, while indigestion was the most common side effect from the subjects with consuming herbal medicine.

Purpose: The aims of this study are to examine clinical characteristics, patterns of medical care utilization, and factors which determine medical care utilization of elementary school children with recurrent abdominal pain (RAP), to find posssible factors influencing the onset and the course of the disorder. Method: We performed questionnaires in Kwangju on children from two primary schools from June,1 1998 to June 30 and carried out statistical analysis. Result: 1) Total number of questionnaires were 1417. 715 were male and 702 were female and the ratio of male to female was 1.02:1. Average age was 10.3 years. 2) 268 children had RAP (18.9%), boys 132 (18.4%), girls136 (19.2%). 3) The duration of the pain within 10 minutes was 68.5%. 178 children with RAP (66.3%) visited the doctor. The utilization pattern of medical facilities of the pupils with RAP; the most frequently utilized medical facility was pediatrics (35.2%) and the order ran as internal medicine (31.5%), and pharmacy (29.25). The utilization pattern of medical facilities for the older students; the utilization rate of pediatrics decreased, but internal medicine increased. The major factors affecting the selection of the medical facility were geographic accessibility, kindness of the personnel, good results and traffic convenience. 4) Symptoms which were accompanied with abdominal pain were headache (44.5%), chest pain (28.2%), dizziness (26.6%), vomiting (9%), and 119 children (44.5%) had no accompanied symptoms. 5) In 95 children (35.3%) abdominal pain, occured at postprandial time, in 55 children (20.5%) before meal and in 39 children (14.7%) at school. The highest incidence rate of RAP was observed on Monday (21.4%), and the lowest on Saturday (8.7%). 6) The most frequent involved part of the abdomen was periumbrical area (38%) and the order ran as epigastrium and suprapubic area. The most frequent characteristics of abdominal pain were burning pain (36.9%) and the order ran as dull, cramping and colicky pain. Conclusion: RAP is a frequent disease entitiy in children. Too many times children with RAP are treated by other departments instead of Pediatrics. A child has a peculiar growth and development which is different to those from an adult with advancing years. So, it is necessary to choose special medical care and an adequate medical facility.

Gender diversity policies aim to reduce institutional discrimination in a male-dominated society and the underutilization of women in terms of the economy. Extant gender diversity literature has focused on gender diversity policies premised on women being treated as a minority. However, since women-centered occupational groups do exist, women cannot be considered an absolute minority. Therefore, we explored the gender difference in job seekers' reactions to a diversity policy favorable to men. The experiment divided participants into 2 (Gender: Male, Female) × 2 (Diversity: Favorable, Unfavorable), canvassing 329 college students (156 male, 173 female). Participants evaluated the organizational justice and organizational attractiveness of the virtual company by looking at the diversity cues presented in the job posting seeking new employees. As a result, it was confirmed that if the diversity cues presented in the job posting were favorable (vs. unfavorable) to the individual, the organization's distribution justice and procedural justice perceptions were generated differently according to the gender of the job seeker. Moreover, female job seekers perceived distribution justice and procedural justice as higher than male job seekers when they encountered diversity cues that were favorable (vs. unfavorable) to them. In addition, the relationship between diversity cues and organizational attractiveness was mediated by the perception of organizational justice, and this mediating effect was moderated by gender. For women, on the one hand, the mediating effect through the perception of distributive justice and procedural justice was significant in the relationship between diversity cues and organizational attractiveness. On the other hand, the mediating effect alone through the perception of procedural justice was significant for men. Our findings suggest that identical diversity managements are distinguished by individuals' social status or affiliation and may even result in differentiated behaviors.

The survey on dental health condition and eating habit of local residents in Daegu and Kyungbuk had been conducted. Through the analysis of influence of dental health condition on eating habit I could get the following result. The number of subjects of survey is 630. The period of survey is from June 2006 to September 2006. 1. General quality of subjects is that forty-four point four percent of subjects are male and fiftyfive pointsix percent are female. The age of thirty point one percent of subjects is between 20 and 29. Fifty-six point two percent of subjects are married. Fifty-one point four percent of subjects have above bachelor degree. Monthly income of forty-four point eight percent of subjects is less than one million won. Twenty-four point four percent of subjects are students. Fifty-five point seven percent of subjects are living in big cities. 2. Forty-seven point seven percent of male and fifty-one point eight percent of female answered their subjective dental health condition is bad. Marital status, age and academic background have relationship with answer. Forty-three point nine percent of married subjects and forty-one point five percent of divorced or bereaved subjects said they have bad dental health condition. The older he is or the lower academic background he has subjects think they have bad dental health condition. Forty-seven point four percent of non-educated subjects answered their dental health condition is bad. Forty-six percent of self-employed subjects and subjects who live in the country have tendency to think their dental health condition is bad. 3. About eating habit knowledge, male's knowledge of 2.03$\pm$0.20 is lower than female's of 2.08$\pm$0.21. This shows there is statistically significant difference(p<0.01). 4. There is significant relationship between subjective dental health condition and health condition of subjective. This means subject who has better health condition has also better dental health condition(37.5%). About subjective dental health condition, subject who eats restoratives has worse dental health condition. This shows there is a relationship between dental health condition and eating restoratives(p=0.004) and subject who works out steadily has better dental condition. 5. About relation between dental health condition and eating habit, subject who eats vegetables has worse dental health condition by fifty point seven percent. As cross tabulation result, p-value is 0.002. In level of significance of 0.05, there is statistically significant difference in eating habit. 6. It seems that eating habit has an effect on marital status, age, academic background, income and also on dental prosthetic treatment situation. Many subjects think their dental health condition is bad. About eating habit, subjects who eat meat have better dental health condition. Subjects who drink green tea and fruit juice has better dental health condition than who drink coffee and Balanced diet is good for dental health condition. As eating habit is important for developing dental health, government should make a proper program. Dental health education program especially for elderly, low-eduacted, residents in the country and poor people should be developed. Government, dental health organization, dental health specialist, associated research institution and people work in the press should be concerned and devote to improve quality of life. Primary prevention education will help for dental health.

Objectives : The objective of this study is to find out the differences in psychopathology, temperament, and character factors between young adults with and without childhood attention-deficit hyperactivity disorder (ADHD) symptoms. Methods : The subjects consisted of 314 university students (male=72, female=242) in Gongju. They were divided into childhood ADHD group (N=54) and normal group (N=260) to the Wender-Utah Rating Scale. Participants were assessed using Korean Adult ADHD Scale, Beck Depression Inventory-II, Beck Anxiety Inventory, Kimberly Young's Internet Addiction Test, Barratt Impulsiveness Scale, Paranoia Scale, Korean-Schizotypal Ambivalence Scale, Lubben Social Network Scale, and Temperament and Character Inventory-Revised. Descriptive statistics, t-test, chi-square, spearman correlation, and stepwise multiple regression were applied to analyze the data. Results : Participants with childhood ADHD symptoms had high level of adult ADHD symptoms (p<.001), impulsiveness (p=.001), depression (p<.001), anxiety (p<.001), internet addiction (p<.001), paranoia tendency (p<.001) and low level of selfesteem (p<.001) compared to normal group. Self-directedness (p<.001) was lower, Harm avoidance (p=.001) and Self-transcendence (p=.029) were higher in the childhood ADHD group. In correlation and stepwise multiple regression, childhood ADHD symptoms were significantly associated with cooperativeness (r=-0.515 and ${\beta}$=-0.547, p<.001 respectively). Conclusion : This result showed that young adults with childhood ADHD symptoms had various forms of psychopathology and childhood ADHD symptoms were influenced by character such as cooperativeness. Therefore, more thorough evaluation regarding childhood ADHD symptoms is needed.

This research was performed to confirm the four emotional eating types and examine the differences in BMI, ego resilience, and the level of college adaptation among those types. The total of 485 Korean college students (male 249, female 236) participated in this study. The main results were as follows, First, the emotional eating types were divided into four types based on positive emotional eating and negative emotional eating, and the type of more - eating with positive emotion and less? eating with negative emotion was the largest one among all the types. Second, there were no significant distinctions on frequency between emotional eating types and BMI. Third, individuals with less - eating for both positive and negative emotions showed the highest ego resilience level, whereas those with more - eating for both positive and negative emotions showed the lowest. Fourth, individuals with less - eating for both positive and negative emotions showed the highest score in the level of adaptation in college whereas those with more - eating for negative emotion and less - eating for positive emotion showed the lowest. Limitations of the present study and suggestions for future research were discussed.

The purpose of this study was to evaluate the characteristics of craniofacial skeleton on orthognathic surgical cases with skeletal Class III malocclusion. For this study, 74 students at the dental college of Chosun University volunteered as a normal occlusion group. They had well-balanced faces and good occlusions with acceptable Class I molar relationship. They had not received orthodontic treatment and had no signs or symptoms of temporomandibular joint dysfunction. 45 malocclusion patients enrolled for orthognathic surgical treatment with skeletal Class III malocclusion at the Department of Orthodontics, College of Dentistry, Chosun University. On the basis of this study. the results of this study were as follows: 1. Skeletal Class III malocclusion was largely due to the overgrowth of mandible in man and the undergrowth of maxilla in woman. 2. The mandible was antero-inferiorly overgrown by large MP-HP angle and large genial angle in orthognathic surgical cases with skeletal Class III malocclusion. And also, upper incisors were severely labioversioned, but on the other hand lower incisors were linguoversioned. 3. In female, lower-third facial height was characteristically shortened in comparison with middle-third facial height and also, lower facial throat angle was small in male.
