The results of this study can be summarized and compared the primary examination with the secondary test of greater than $10^{\circ}$of Cobb's Angle were obtained as follows; 1. Indirect Examination were conducted to find idiopathic scoliosis amomg total 2.787 subjects, 257 subjects (9.2%) who showed positive sign greater than $10^{\circ}$in the Cobb's Angle ; below age of thirteen (132 subjects), between fourteen and sixteen (52 subjects), seventeen and eighteen (35 subjects), nineteen and twenty four (38 subjects). The $x^2-test$ analysis of Indirect Examination showed no statistical significant difference association between the age range and $10^{\circ}$Cobb's Angle of spinal curve(P>0.059). 2. The numbers of idiopathic scoliosis of greater than $10^{\circ}$Cobb's Angle of spinal curve in the primary examination were observed in 147 subjects (57.2%) at the Thoracolumbar region, 81subjects (31.5%) at the Thoracic region, 20 subjects (7.8%) at the Cervicothoracic region, 7 subjects (2.7%) at the Lumbar region, 2 subjects (0.8%) at the Cervical region. So, the large numbers were Thoracolumbar region, 183 participants (71.2%) showed the right side curve of scoliosis and 74 participant (28.8%) showed the left side curve of scoliosis. 3. The main region of the pain in one's own self more than $10^{\circ}$ Cobb's angle of spinal curve were no pain 219 subjects (85.2%), 18 subjects (7.0%) at the Lumbar region, 9 subjects (3.5%) at the Cervical region, 7 subjects (2.7%) at the Thoracic region, 2 subjects (0.7%) at the shoulder girdle region, 1 subjects (0.39%) at the pelvis and whole body region. There was statistical significant difference association between the Cobb's Angle of spinal curve and the main pain region of one's (P<0.006). This study may be significant to an early stage investigate of the prevalence rate of idiopathic scoliosis in the juveniles using 100 mm Mirror Camera radiation indirect examination units. The results of this study help that the students in a stage on growth the basis of data early discovery and therapy of idiopathic scoliosis.

The purpose of this study was to examine the perception of health-related majors in their third year of college about the image of a dental hygienist as prospective dental personnels. The findings of the study were as follows: 1. Concerning perception of the image of a dental hygienist by geographic region, the college students from large cities gave 89.07 to that, and the college students from small and mid-sized urban areas gave 85.03. The former gave higher marks to the image of a dental hygienist, and the gap between the two was statistically significant. By department, the students who majored in physical therapy gave the highest score of 88.93, dental technology and radiology gave the second highest score of 86.91. The clinical pathology gave the third highest score of 83.28, and the gaps among them were significant. 2. As for their perception of the four subfactors(qualifications, roles, social participation and interpersonal relationship) of the image of a dental hygienist by geographic region, there were statistically significant gaps in their way of looking at the qualifications, roles and interpersonal relationship of a dental hygienist. By department, the physical therapy majors gave the highest marks to all the four subfactors. 3. When they were asked to give one or more answers to the question what affected their image building about a dental hygienist, the largest number of the students that accounted for 67.9 percent replied that the looks of dental hygienists whom they saw in dental clinics or hospitals impacted on their image of a dental hygienist.

The decrease of bone mineral density gives rise to the outbreak of osteopenia and makes the possibility of a bone fracture. It makes health problems in society. It's very important to prevent osteopenia in advance. Also it's critical to prevent and take care of it in adolescent because it's the most developing period comparing to middle ages because that bone mineral density decreases. There are genetic, physical and enviromental factors that affect bone mineral density. Recently, a lifestyle and eating habits are also changing as the society atmosphere is gradually doing. This study have shown that 134 women and 75 men was chosen and responded to the survey of measuring bone mineral density and investigating a lifestyle. The measure of bone mineral density is to use Dual energy X-ray absorptiometry(DEXA) and check femoral neck and lumbar spine. Also questionaries was required to pre-made survey about their lifestyles. Analysis of data was done with SPSS program. Multiple regression analysis was used for the relation of bone mineral density, the heigths and BMI. The sample of Groups are checked for drinking, smoking or excercising about differences by t-test. The results of the experiments were; first, there is statistically significant differences in the comparisons between BMD and BMD. But there isn't any special correlation between drinking, smoking and BMD. Secondly, bone mineral density becomes low related to an intake of caffeine. Particularly, this is statically significant on women. Also there is statically significant correlation between femoral neck and quantity of motion for both men and women. Third, there is significant relation between eating habits and bone mineral density on women's lumbar spine. However, there is no significant relation between men's lumbar spine and women's one. Therefore, to prevent osteopenia, it's good to abstain from intaking caffeine within an hour after a meal. In addition, it's helpful to walk or run regularly and have a balanced meal.

RI-Biomics is a promising radiation convergence technology that combines radiation with bio science as new growth power technology. Many developed countries are focusing active support and constant exertion to dominate the RI-Biomics market in advance. In order to achieve global leadership in the RI-Biomics field, we need more highly advanced technologies and professional manpower. In fact, we have less manpower compared to technology we currently hold. In this study, we established a basic infrastructure to train professional manpower in the RI-Biomics field by developing/operating optimum training program through expert interviews and survey. The developed program has four organized sections to understand overall procedure of RI-Biomics. To evaluate our training program, we performed test operations with eight students who have a major related to RI-Biomics for three weeks in KARA (Seoul) and KAERI (Jung-eup). In detail, radioisotope usage and safety management were conducted for one week as basic course, RI-Biomics application technology was conducted for two weeks as professional course. To verify performance results of training program, we conducted to journal research, daily reports, and survey on participants. The results show a high level of satisfaction with training programs and continuous intention of involvement in our program. We also need to develop an intensive course to train high-quality human resources and to operate training program continuously. This training program will be used as basic materials for the development of RI-Biomics curriculum for university. Hence, we will expect that our training program contributes in training a professional manpower and develop RI-Biomics technology.

This study was conducted to provide fundamental data on the awareness of radiation, specifically the differences between general awareness, psychological state and harmful effects. Data was collected from 334 University students in the Chungbuk region through a self-administered questionnaire. According to the results of the reliability and factor analysis, the awareness of radiation was 2.80, with a Cronbach alpha coefficient of 0.815 and KMO of 0.798. Factor analysis extracted three components of the awareness of radiation, which we named general awareness (factor 1), psychological state (factor 2), and harmful effect (factor 3). There were significant differences in the general awareness of natural radiation and radiation-containing foods (p<0.05), whereas no significant differences were found in the general awareness of radiation food supply (p>0.05). Also, the psychological state showed a significant difference in exposure inspection, future exposure, and radiation-containing food (p<0.05), whereas no significant differences were found in the refusal of radiation inspection (p>0.05). The harmful effects showed a significant difference in the rejection of radiation (p<0.05), but no significant differences in the cancer and genetic effects, diseases and physical harmfulness (p>0.05). A significant positive result (p<0.05) was found for the psychological state according to the harmful effects of radiation. Based on this study, detailed and continuous education must be accomplished by increasing the awareness of radiation and the acceptance level, conveying a proper understanding of radiation and assisting subjects with receiving the information they desire through various educational mediums.

This study was to find out the correlation between abdominal surface temperature and abdominal fat areas. CT and MRI methods have been used to assess abdominal fat area. Abdominal surface temperature according to abdominal fat area was also measured by DITI. 20 college students were selected as the subjects for the study. The results, showed that there were statistically different significance in abdominal fats measured by CT and MRI according to weight groups. Abdominal surface temperature gap were measured by DITI and there was a statistically significant difference in only T12 region. temperature gaps between weight groups were over $0.7^{\circ}C$. In conclusion, CT method is the most accurate method to measure abdominal fat. However, weak points are radiation exposure and high cost for study. The correlation between abdominal surface temperature and abdominal fat areas were strong. Therefore, DITI may be considered as useful convenient method to evaluate the abdominal obesity and clinical usefulness.

A survey was conducted to examine the knowledge and acceptance of food irradiation in order to provide baseline data required in the development of food irradiation education programs for college students. 150 students majoring in food and nutrition or food technology in the Chungnam National University were chosen for a survey. The results are as follows. First, college students' knowledge about food irradiation is scanty. Knowledge assessment showed that 56% of the participants had previously heard of food irradiation. 68% of the respondents thought that radioactivity remains in food after irradiation and 25.3% of them were not sure whether radioactivity remains in food after irradiation or not. Only half of the respondents thought that nutrient loss due to irradiation is equal to or lower than that due to cooking or freezing. Second, approximately 56% of the respondents showed that food irradiation is somewhat or strongly needed for meat or fish; whereas, over 60% of them showed that food irradiation is not needed for grain, vegetable and fruit. Almost 40% of the respondents were seriously concerned about irradiation of vegetables and fruits; whereas, they showed less concern about spice irradiation. More than half of the respondents were not willing to use irradiated food in all the six food groups. Third, the correlation analysis showed that the need of food irradiation is negatively correlated with concerning about the irradiated fish and fruits, but positively correlated with willingness to use irradiated food in all the five food groups, except in spices. Concern about the irradiated food is negatively correlated with willingness to use irradiated food from all the six food groups. Fourth, almost all the respondents (over 90%) agreed that the irradiated food labeling is required as well as the development of proper methods to identify irradiated foods.

A survey was conducted to examine the effect of food irradiation education on college students' knowledge and acceptance of food irradiation. The instrument for the knowledge and acceptance of food irradiation was administered before and after food irradiation education, to 150 students majoring in food and nutrition or food technology in the Chungnam National University. Before the education approximately 93% of the respondents did not know that radioactivity dose not remain in food after irradiation; whereas, after education half of them thought that radioactivity dose not remain in irradiated food. Knowledge about food irradiation has improved through education. The education significantly increased all the mean scores of need for food irradiation and willingness to use irradiated foods for the six food groups (p<0.01). The education significantly decreased the mean scores of concern about the irradiated food for all the six food groups (p<0.01). Although the responses to irradiated foods are, in general, negative or neutral even after education, the mean scores of acceptance of the irradiated foods have improved through education in all the six food groups (p<0.01). In conclusion, this study showed that food irradiation education may positively affect the college students' knowledge and acceptance of food irradiation, and that the development of both the appropriate detection methods to identify irradiated foods and the education programs to enlighten the college students are needed.

Objective: The purpose of this study was to evaluate the effects of malocclusion on the self-esteem of female university students. Methods: The subjects were composed of 67 female university students who showed Class 1 molar relation, no missing or supernumerary teeth and has had no orthodontic treatment experience. Each subject was evaluated with Rosenberg's Self-esteem Scale to measure the level of self-esteem and also evaluated the degree of anterior crowding and lip protrusion through model analysis and cephalometric soft tissue profile analysis. Results: The results showed that a protrusive profile and crowding of upper anterior teeth had significant reducing effects on the level of self-esteem. The protrusion and crowding groups showed no significant differences in self-esteem between groups. Conclusions: Malocclusion had significant negative effects on the self-esteem of female university students. Further research to investigate the negative psychological influence of malocclusion and the education of lay people about this influence is necessary.

The purpose of this study was to investigate food safety awareness, knowledge, and behavior in college students, to provide basic data for the increase in food safety awareness. Data were collected from 252 college students in Gyeonggi region, using a self-administered questionnaire. In results of concern about food safety, subjects responded 3.48 of 5.00 and have knowledge about food safety education revealing significantly higher awareness and concern than subjects without knowledge about food safety education. Food safety awareness of distributed food was 2.55, considered unsafe. Among reasons in perceiving food as unsafe, 62.3% of subjects expressed distrust about safety relative food production. As for risk factors relative to food safety, subjects responded that the highest risk factor was food additives (2.35), followed by heavy metal (2.38) and endocrine disrupters (2.38). Correlation analysis resulting in risk factors for food had positive correlation with each other, heavy metal revealed highest correlation with pesticide residue (r = 0.674), than with endocrine disrupters (r = 0.672). Also, genetically modified food revealed high correlation with radiation irradiated food. Regression analysis demonstrated that concern about food safety significantly influenced pro-actively engaging in food safety education. Meanwhile, 63.5% of subjects correctly responded to food safety knowledge items. The item 'the heavy metals are contaminated the most, in the roots of vegetables' revealed the lowest correct answer rate (38.1%). In food safety behavior, the item 'always wash hands before handling food and meal's revealed 3.85, and subjects with awareness and concern about food safety education, responded in significantly higher numbers than subject without awareness and concern about food safety. The most neglected concern was relative to frozen food thawed at room temperature. Together, students recognize that distributed foods are unsafe, and students with awareness and concern about food safety education showed higher knowledge compared to without awareness and concern experience about food safety eduction. So, systematic education using accurate and objective data is required to reduce anxiety and raise the level of awareness and concern about food safety.
