By means of the statistical data which has been collected with newly revised QSCC made use of the outpatient group examined at Kyung-Hee Medical Center and an open ordinary person group, the author proceeded statistical analysis for the validation study of the revised questionnaire itself. First, check the accurate discrimination rate by performing discriminant analysis on the statistical data of the patient group. And next, sought T-score by applying the norms gained in process of standadization of the open ordinary person group to the Sasang scale score of the outpatient group and investigated the distinctive feature between the subpopulations which was devided in the process of multivarite cluster analysis. The result was summarized as follows ; 1. The validity of the questionnaire was established through the fact that the accurate discrimination rate the ratio between predicted group and actual group was figured out 70.08%. 2. At the profile analysis the response to the relevant scale showed notable upward tendency in each constitutional group and therefore it seems to be pertinent in the field of constitutional discrimination. 3. In the observation of the power of expression through the profile analysis of each constitutional group the Soyang group demonstrated the most remarkable outcome, the Soeum group was the most inferior and the Taieum group revealed a sort of dual property. 4. What is called the group of seceder out of three subpopulation of each constitutional group distinguished definitely from the contrasted groups at the point of the distinctive profile feature and the content is like following description. (1) The seceder group of Soyang-in showed considerably passive disposition differently from general character of ordinary Soyang group and an appearance attracting the attention is that they demonstrated comparatively higher response at Soeum scale (2) The seceder group of Taieum-in gained low scores in general that informed the passive disposition of the group and the other way of the general property of Taieum group which showed accompanied ascension in Taiyang-Taieum scales they demonstrated sharply declined score at Taiyang scale (3) The seceder group of Soeum-in demonstrated distinctive property similar to the profile feature of Soyang group and it notifies that the passive property of Soeum group was diluted for the most part. According to the above result, the validity of newly revised questionnaire has been proven successfully and the property of seceder groups could be noticed to some degree through the profile analysis on the course of this study. The result of this study is expected to use as a research materials to produce next edition of the questionnaire and it is regarded that further inquisition about the difference between the seceder group and the contrasted group is required for the promotion of the questionnaire as it refered several times in the contents of the main discourse.

Introduction The aim of this study, personal trait and their dental care based on experience level of dental fear is to analyze the differences. Catastrophizing is an irrational belief that something is far worse than it actually is. Because it makes it possible to analyze patients' anxious thoughts and tendencies. Methods The Dental Fear Survey(DFS) and Anxious Thoughts and Tendencies(AT&T) were used as measuring tools, and the independent sample t-test and ANOVA were performed on the basis of the mean value of the summated scale scores and the standard deviation. On the factors to dental anxiety, the multiple regression analysis was performed. Results Demographically, the total DFS score was higher in women($25.73{\pm}8.27$) than in men. Also, AT&T was higher in women($31.01{\pm}7.05$) (p<0.05). Dental fear was intense in the group of patients who visited dental clinics only problems($25.29{\pm}8.57$) than in those regular visited($22.29{\pm}7.78$). In relation to dental experiences, the DFS score was significantly higher in children. In many cases, patients experienced therapeutic pains in children($26.40{\pm}9.54$) (p=0.004). Also in many patients, dental anxiety began to occur in adolescence(44.3%). The multiple regression analysis result, it was found that dental treatment pain and their AT&T wielded great influence upon dental fear.

This study was conducted to investigate dietary factors, bone status, and bone loss in postmenopausal women in rural areas. A total of 189 women participated in the follow-up study after two years. Radius, Tibia, and Phalanx SOS (Speed of Sound) was measured on two occasions 2 years apart by ultra-sonic-metry, and % body fat was measured by bioelectrical impedance analysis at the baseline and after 2years. Dietary intake data were collected 4 times at different season by 24-hour recall method, and then calculated as average. Bone density of radius decreased by 4.2% during the two year period. When the subjects were divided into three groups, by bone decline level during two years, the lowest bone loss group had higher potassium and vegetable intake than other groups. Age and calcium intakes showed significant correlation with bone decline rate at tibia. In multiple regressions, the baseline SOS, vitamin A, vegetables and eggs intakes were found to be significant factors for tibia bone decline. In conclusion, dietary factors, such as higher vegetable intake, seem to affect the changes in bone mineral density in more favorable way. Therefore, efforts are needed to enhance the access to nutritional care for rural elderly postmenopausal women.

Purpose: This study aims to provide baseline data on children's health care and household safety management in one region and to support implementation of customized visiting health care services for children. Methods: 51 children and their caregivers from socially vulnerable group and 69 children and their caregivers from general group are selected as research participants. Data were collected through home visiting survey by 10 professional nurses. Results: Children from socially vulnerable group are at higher risks of poor health care and safety accidents in households than general group. Rates of taking developmental screening tests, medical check-up remain considerably low in vulnerable social group. Regarding home safety, vulnerable children are more likely to be exposed to unsafe conditions. Conclusion: These results indicate that in order to promote health care and safety conditions for vulnerable children, it is necessary to implement customized visiting health care programs which actually can reach vulnerable households and meet their demands. These findings can be used as baseline data to develop customized visiting health care programs for children.

In construction sites, many accidents occur without supervisors during night work, early work, and lunchtime work outside of regular working hours. The purpose of this study is to measure the safety level of workers and to provide basic data for preventing accidents during vulnerable times by analyzing the opinions of expert groups on working conditions. Working conditions were divided into four areas: basic conditions, physical environment, social environment, and physiological factors. After examining the correlation between the priority considerations determined by Analytic Hierarchy Process (AHP) and the safety level of workers investigated in advance, management plans for each factor was derived.

The purpose of this study is to classify the subtypes of perpetrators of school violence based on their psychological characteristics. In order to classify the students, questionnaires/interviews which consist of 6 factors (Cognitive Impulsivity, Unplanned Impulsivity, Depression, Anxiety, Peer Conformity, and Self assertion) and 19 questions were administered to 86 perpetrators of school violence. Then, a two-step cluster analysis was performed with the survey results of 74 perpetrators. As a result, three clusters were identified and named as follows: 1) Impulsive Vulnerability, 2) Emotional Vulnerability, and 3) Social Vulnerability. Scrutinizing the detailed characteristics of each cluster, the first cluster, Impulsive Vulnerability, showed higher scores on Cognitive Impulsivity and Unplanned Impulsivity, compared to the other two clusters, while Depression and Anxiety scores were lower. The second cluster, Emotional Vulnerability, showed higher scores on Depression and Anxiety, while Cognitive Impulsivity and Unplanned Impulsivity scores were lower. The third cluster, Social Vulnerability, showed the highest score on Peer Conformity among the three clusters. However, Self assertion scores were the lowest in this cluster, and Cognitive Impulsivity, Unplanned Impulsivity, depression, and anxiety scores were lower than in the others. This study will provide a useful insight for facilitating teachers and parents' understanding of the psychological characteristics of school violence perpetrators and thereby contributing to effective intervention.

Effective and efficient estimation of camera poses is a core method in implementing augmented reality systems or applications. The most common one is using markers, e.g., ARToolkit. However, use of markers suffers from a notorious problem that is vulnerable to occlusion. To overcome this, this paper proposes a top-down method that iteratively estimates the current camera pose by using particle swarm optimization. Through experiments, it was confirmed that the proposed method enables to implement augmented reality on severely-occluded markers.
