Objectives: The purpose of this study was to investigate the relationship between the level of subjective stress recognition and oral symptom experiences including toothache, gum diseases, and oral soft tissue diseases in the Korean adolescents. Methods: The subjects were 68,043 adolescents recruited using a web-based survey, National Korean Youth Risk Behavior in 2015 by the Korean Center for Disease Control. For statistical analysis, SPSS 21.0 for Windows was used. Descriptive analysis and a Chi-square test were conducted to determine the factors associated with general characteristics, health behaviors, oral health behaviors, and level of subjective stress recognition. Finally, to investigate the relationship between the level of subjective stress recognition and oral symptom experiences, logistic regression analysis was performed. Results: Toothache related subjective stress recognition level was significantly higher in the moderate group with the score of 1.59 (95% CI; 1.49-1.68), and was greater in the high group with 2.38 (95% CI; 2.24-2.53) compared to the low group. Gum disease related subjective stress recognition level was significantly higher in the moderate group with 1.41 (95% CI; 1.32-1.51), and was greater in the high group with 1.99 (95% CI; 1.86-2.13). Oral soft tissue disease related subjective stress recognition level was significantly higher in the moderate group with 1.59 (95% CI; 1.45-1.74), and was greater in the high group with 2.55 (95% CI; 2.33-2.79). Bad breath related subjective stress recognition level was significantly higher in the moderate group with 1.48 (95% CI; 1.39-1.57), and was greater in the high group with 2.10 (95% CI; 1.97-2.25). Conclusions: Higher subjective stress recognition level was found to affect the oral symptoms experienced. Therefore, the stress management plan should be prepared through the cause identification of the main stress in the adolescents. Practical and systematic education is needed for oral health management in the schools.

The purpose of this study was to provide information on the development of an oral-health promotion program geared toward office workers. The subjects in this study were 240 employees at the headquarters of S construction company. After a survey was conducted in July and August 2008, the answer sheets from 208 respondents were gathered, and 191 answer sheets were analyzed except 17 unanalyzable ones. The findings of the study were as follows: 1. In regard to subjective oral health status, the largest number of the participants that accounted for 37.2% found their mouth to be neither healthy nor unhealthy. The greatest number of them that represented 58.1% had never visited a dentist's office to receive preventive treatment. 2. Regarding relationship between toothbrushing education experience and toothbrushing frequency, the most common toothbrushing frequency was three times a day( 46.5%) among the company employees who had ever received that education. In the event of the office workers without that experience, the most prevalent frequency was three times(63.6%). The toothbrushing frequency was statistically significantly different according to the toothbrushing education experience(p<0.05). As to the relationship of toothbrushing education experience to tooth- brushing method, the largest number(48.2%) of those who had ever received that education brushed their upper and lower teeth along with the gums by rotating the toothbrush downward from the top and upward from the bottom respectively. In the event of the office workers without that experience, 49.4 percent brushed their teeth and gums by rotating the toothbrush up and down. Thus, whether they had ever received education about toothbrushing made a statistically significant difference to their toothbrushing method(p<0.05). 3. As a result of evaluating their oral health belief by utilizing a five-point scale, they got a mean of 2.95. In each area of oral health belief, they got the best marks in benefit(3.66), salience(3.42), barrier(2.84), susceptility(2.58) and seriousness(2.23). Given the above-mentioned finding of the study, two sorts of oral health beliefs, which are benefit and salience, should be stressed in the development of oral health education programs that cater to company employees. And sustained research efforts should be channeled into finding out the relationship between oral health and actual oral health care.

The purpose of this research is to investigate the attitudes of students, who are used to study at the Library of Duksung Women's University, concerning about the loss and mutilation of books, articles and other research materials m a university library, and to take measures for preventing the library materials from being lost and mutilated. This study made the surveys of student's recognition about the immoral behaviors like larcenous and mutilating acts, the causes of such destructive works and effective preventive measures to keep library materials in good condition, including student's opinion about library services. The investigations were conducted in two times with the same questionnaire on randomly selected 480 students and 540 students of 1989 and 1994 respectively. The sample size is estimated to reach each $10\%$ of the total number of students of 1989 and 1994 in Duksung Women's University. And then, the students were divided into two groups. The one is a group that has had experiences stealing and mutilating the materials from the Library of the University. The other is another group which has done none of them. Thereafter the responses of the two groups are analyzed to compare the differences of the students' behaviors between 1989 and 1994, and thereby finding out important factors inviting the loss and mutilation and accordingly improving effective checks to deter the students from stealing and mutilating the library materials. Some of the research findings suggested in this paper are pointed out as follows: 1) The students who has experienced neither stealing nor mutilating the library materials visited the library more frequently and are more serious about such destructive behavior as stealing and mutilating. 2) The attitudes of the students about services and equipments supplied by the library are slightly different among the students who experienced such immoral activities or not. For example, the experienced students had more preference about an application of self-help duplicating machine being able to use card. 3) To prevent the students from stealing and mutilating the library materials, the non-experienced students demanded an education for them to duly recognize the public interest of the library and also suggested to keep more duplicate materials ready in the library, meanwhile, the experienced students indicated strongly such proposals as strict regulations against stealing and mutilating behaviors, having a correct understanding of costing a lot of time and money to restore the damaged materials to their original state and keeping many duplicates ready in the library. 4) It appears to be that there were different between the experienced and non- experienced students concerning causes invited stealing and mutilated behaviors. 5) Over all, the number of the non-experienced students is more increased in 1994 than that of 1989.

The aim of the study was to examine levels of satisfaction with health care in North Korea and to identify factors associated with it using a convenience sample of North Korean refugees in China. Data from the 2004 Survey of Health Seeking Behavior of North Korean Households conducted by the Center for Refugee and Disaster Response, Johns Hopkins Bloomberg School of Public Health were used. The study subjects were 273 North Korean refugees whose length of stay in China was less than 3 months. Factor analysis was used to extract factor dimensions from the 12 satisfaction items. Bivariate (t test and ANOVA) and multiple regression analyses were used in examining factors associated with satisfaction with health care use in North Korea Overall, satisfaction level was low ($2.36{\pm}0.36$, score range: 1-5). Of the three-factor dimensions, physician skills scored the highest $(2.93{\pm}0.36)$, followed by drug availability $(2.51{\pm}0.07)$ and general cleanliness $(1.66{\pm}0.55)$. In the multiple regression analysis, having a usual source of care was significantly associated with patient satisfaction. Respondents who identified primary care (section) doctors as their usual source of care tended to be less satisfied than those with the city or county hospital as their usual source of care. County residents tended to report a lower degree of satisfaction with general cleanliness than city residents. Among socioeconomic characteristics, the number of household assets positively predicted satisfaction with drug availability. North Korean residents appear to be dissatisfied with their medical care. It may reflect some inadequacies in the North's universal health care system to meet the healthcare needs of its people.

The present study was conducted to assess relative importance of hospital attributes considered by patients with spinal diseases in choosing specialty or general hospitals. A total of 230 patients hospitalized with spinal diseases in sampled study sites, including 2 specialty and 2 general hospitals, participated in a self-administered questionnaire survey from April 26 through May 8 2007. Patients were asked to rate the degree of agreement on each of the 15 attributes on a 5-point Likert-type scale (1 : strongly disagree, 5 : strongly agree) for which they chose the hospital because of that specific attribute. Based on a Factor analysis, the attributes were grouped into 4 : facility and environment, accessibility, interpersonal factor, and credibility. Both patient groups from specialty (mean scale score ; 3.75) and general hospitals (3.62) commonly considered 'credibility' to be the most important attribute, followed by 'facility and environment (3.05 and 3.21).' Logistic regression analysis showed that men(Odds ratio(OR)=0.333) and those with monthly income of $\geq$ 4 million won (OR=0.298) were less likely to choose specialty hospitals. Age groups of 30 to 39 years old (OR=5.140) and $\geq$ 60 years old(OR=4.761), and professionals (OR=5.207) tended to choose specialty hospitals. Patients expressing more importance on 'facility and environment' attribute were less likely to use specialty hospitals (OR=0.571), whereas those emphasizing 'accessibility' were more likely to use specialty hospitals(OR=1.487). The findings of significant difference in patient's demographic characteristics and consideration in hospital attributes would contribute to have a better understanding on patient's choice behaviour and to develop strategy to improve patient's satisfaction.

Accidents are important causes of death and disability in children. They also have enormous financial implications. Young children become an victim of accidents easily because of their physical fragileness and their coping behavior being vulnerable to any actions taken by accidents. Once they have a accident, the children whose not fully developed, suffer from devastating long-term after-effects. Lee, Lee, Kang and Han(1995) reported that ninety percent of accidents can be prevented. But there is no national system to manage, evaluate and analyse the information about child accidents, even though it is necessary for accident prevention policies and health promotion of the general public. The purpose of the study was to determine how often children have accidents and define the accident prevention strategies in children. The investigator conducted a descriptive study by performing the surveys, interviews, and workshops for the 2,458 young children, 10 teachers, and 1,494 parents. The data collection for the study began on September 2000 and completed on April 20, 2001. The analysis of the data was done with Window SPSS 10.0 for descriptive statistics. Among those children, 1,298 children(52.8％) injured from accidents. The children who had accident answered that they injured from traffic accident(27.3％), inside the home(26.3％), on the playground(17.0％), during playtime(13.6％), in the school(5.9％) and food poisoning(7.1％). To define accident prevention strategies for the school children, the parents and the teachers who had a special interest in this topic formed a special task force under the guidance of the investigator. The team was charged to prepare the basis of content materials by identifying the problems, setting standards for the program, prioritizing the process, and selecting the methods of implementation and evaluation. Eight issues and concerns identified by the team were: 1)allowing young children to learn undesirable habits and behaviors that would bother others without knowing; 2) not guarding young children from car accident; 3)unattended accident at playground; 4) considering home places safe; 5)unattended accident at school. These issues were found to be coinciding with the actual child accident cases occurred recent years in Korea. Greater efforts are required to reduce unnecessary deaths and disability from childhood accidents. This study gave a very useful and important data to prepare accident prevention educational program and to prepare accident prevention strategies.
