  • 2010년 3월 11일 대한민국 동해를 건너 위치한 일본에서 강진과 해일로 인하여 후쿠시마원전이 중단되고 폭발하여 방사능물질이 누출되었다. 한 국가에서 발생한 사고지만 누출된 방사능 물질은 해류와 기류를 타고 전 세계에 확산되었다. 국내에도 사고 이후 방사능비가 내린다는 공포심에 혼란이 있었고, 사고 발생 1년이 지나도 방사능오염에 대한 문제는 해결되지 않고 있다. 즉 이웃나라의 원전사고는 국내에도 큰 위협이 되는데 일본 뿐 만 아니라 서해 건너 중국해변에도 원자력발전소가 위치하고 있다. 이웃나라의 원전사고 위협이외 군사적 대치를 하고 있는 북한은 세계3위의 생화학무기 보유국이며 2010년 11월에는 연평도 포격도발을 하는 등 언제든 남한에 생화학물질을 살포 할 수 있는 상황이다. 본 연구는 이러한 위협에 대응하는 전략으로 기상조절기술인 인공강우기술을 접목해 보았다. 원전사고시 방사능물질과 북한의 생화학무기는 기상조건에 따라 농도가 달라 질 수 있으므로 인공강우기술만으로 완벽하게 위협을 제거할 수 없지만, 심리적 측면과 피해저감을 위한 방법으로 시도해 볼 가치가 있다. 국민안전확보를 위한 국가의 안보측면으로서 인공강우기술을 사용하기 위해서는 ADD와 같은 연구기관에서 상시적이고 적극적으로 기술연구개발을 해야 할 것이다.

  • Purpose: This study was aimed to identify the difference of the self-efficacy and the health promoting behaviors between obese and normal-weight middle school students. Method: Data were collected from a convenient sample of 360 middle school students (180 normal-weight students and 180 obese students) in Pusan from November 22nd to December 20th. 2000. based on self-report questionnaires. The following instruments were used in the study after being reconstructed by the researcher with the consultation of experts and the literature review: General Self Efficacy Scale(Sherer et al.. 1982). and Health Promoting Lifestyle Profile (Walker. Sechrist & Pender. 1987). The data were analyzed with descriptive statistics, chi-square test. and t-test and Pearson's correlation coefficient. Results: 1. There were significant differences in father's obesity (p=.014) mother's obesity (p= .007), sibling's obesity (p=.00l), and school record (p=.001) between obese and normal-weight students. 2. There were statistically significant differences in the score of self-efficacy between the obese and normal-weight students (p=.0001) 3. There were statistically significant differences in health promoting behavior (p= .000) and in six sub-i terns: personal relationship (p =.000), exercise (p=.001), responsibility for health (p=.003), stress management (p = .015), self-actualization (p =.043) between the obese and normal weight students. 4. There were very statistically significant negative correlations between obesity and the self-efficacy (r=-.19. p<.001), health promoting behavior (r=-.18. p<.001), specifically personal relationship(r=-.20. p<.001), stress management (r=-.12. p<.05), responsibility for health (r=-.15. p<.01), and self-actualization (r=-.14. p<.01). Conclusion: According to the above results it is concluded that self-efficacy and health promoting behavior influence the obesity of middle school students. Therefore I recommend adding programs that can lead to improve self-efficacy and health promoting behavior to the obesity prevention programs for middle school students.

  • The purpose of this study was to examine the relationships between mothers' childhood experiences, satisfaction as a parent, spousal support in parenting and their children's perception of their child-rearing practices. The subjects were 321 fifth and sixth graders from two elementary schools in Seoul and their mothers. A revised version of the Mother-Father Peer Scale (MFPS; Epstein, 1983) was used to assess the mothers' child experiences. To measure parental satisfaction, the Parent Satisfaction Scale (PSS; Duke, Rose, & Halverson, 1997) was revised and used. A modified version of the Teamwork of Parenting Alliance Inventory (PAI; Abidin, 1988) was used to assess spousal support in parenting. A modified version of the Child-rearing Behaviors Questionaire (Park, 1995) was used to assess the mothers' child-rearing practices. The data were analyzed with descriptive statistics and a t-test. The results of this study were as follows. 1) Mothers who received a greater degree of independence encouragement and acceptance from their fathers tended to show more warmth/acceptance in their child-rearing practices than those who received a lesser degree of independence encouragement and acceptance from their fathers. Mothers who received a greater degree of independence encouragement from their own mothers tended to show more warmth/acceptance of their children but less permissiveness/nonintervention and rejection/restriction in their child-rearing practices when compared to those who received a lesser degree of independence encouragement from their own mothers. The mothers who received a greater degree of acceptance from their own mothers tended to show more warmth/acceptance of their children but less rejection/restriction in their child-rearing practices when compared to those who received a lesser degree of acceptance from their own mothers. 2) Mothers who had a greater degree of satisfaction as a parent tended to show more warmth/acceptance but less rejection/restriction in their child-rearing practices than those who had a lesser degree of satisfaction in parenting. 3) Mothers who received a greater degree of spousal support in parenting showed more warmth/acceptance in their child-rearing practices than those who received a lesser degree of spousal support.

  • Objectives : The growing elderly population and social changes have fueled a rapid increase in demand for elderly care facilities, but health care services for the elderly, especially oral health services, have long been overlooked. The purpose of this study was to examine the oral health care of elderly residents in elderly care facilities in an effort to provide some information on the elderly's oral health care and the development of dental care programs geared toward institutionalized elderly people. Methods : The subjects in this study were 230 elderly people who were in elderly care facilities in Jeolla Province. An individual interview was held, and they got a dental checkup. As for data analysis, t-test and ANOVA were utilized, and Scheffe post-hoc test was employed. Results : 1. In relation to the subfactors of the quality of life related to oral health, the elderly people investigated got a mean of 4.58, 4.47, 4.38, 4.09, 3.94, 3.91 and 3.76 respectively in activity disorder, mental disorder, social disorder, mental inconvenience, functional disorder, physical pain and physical disorder. 2. Concerning the overall quality of life related to oral health, there were statistically significant gaps in this aspect according to gender, age, presence or absence of systemic disorder, presence or absence of eating difficulties, subjective health status, subjective oral health state and oral health concern. 3. The presence or absence of root caries had a significant relationship to physical pain and social disorder among the subfactors of the OHIP-14, but that had nothing to do with functional disorder, mental inconvenience, physical disorder, mental disorder and activity disorder. Conclusions : The oral health indexes of the institutionalized elderly people in Jeolla Province were measured, and what factors affected the subfactors of oral health was checked. As a result, there appeared a close relation ship between oral health and the quality of life. Therefore effective oral health plans that cater to the elderly should be carried out to improve elderly people's quality of life related to oral health who stay in long-term elderly care facilities. In the future, prolonged research should be implemented from diverse angles for the sake of institutionalized elderly people.

  • Objectives : The purpose of this study was to examine the eating behavior of patients in a bid to facilitate the improvement of their eating behavior, as eating behavior seemed to affect oral health and dietary habits. Methods : The subjects in this study were 235 patients who visited the dental hygiene practice lab at C college in South Jeonla Province. After a survey was conducted, the collected data were analyzed with the statistical package SPSS 12.0. Results : 1. When their self-awareness of dietary habits and oral health was checked in consideration of eating behavior, those who thought they had very good dietary habits and were in good oral health had meals three times a day. Their eating time was very irregular, and they took 15 to 20 minutes to eat. Their overeating frequency was three or four times a week, and their frequency of eating between meals was once or twice a week. 2. On the contrary, the daily eating frequency of the patients who found themselves to have very bad dietary habits and to be in bad oral health was not fixed, and their eating time was neither regular nor irregular. They spent less than 10 minutes having a meal, and their overeating frequency was once or twice a week. Their frequency of having a snack was three or four times a week, and as for food preference, they had a liking for meat. 3. The patients considered themselves to be in better health when they had balanced meals and good eating behavior, namely good dietary habits. And they rated their own dietary habits higher when they were in a good oral state, had no experiences to feel pain in the mouth and didn't receive any dental treatment, namely when they were in good oral health. Conclusions : This study attempted to investigate the influence of eating behavior on oral health awareness. Another limitation of this study is that the geographic scope was just confined to an urban community in South Jeonla Province without checking any possible regional gaps. However, it's quite evident that eating behavior exerts an influence on oral health awareness, and it seems worth doing to examine a larger number of subjects by utilizing objective oral health guidelines.

  • Objectives : The purpose of this study was to examine the relationship of the work environments of dental hygienists to their occupational diseases in a bid to provide some information on their health care, health promotion and the prevention of occupational diseases. Methods : The subjects in this study were 300 dental hygienists who worked in Seoul, urban communities involving large cities and rural areas. One-on-one interviews and a self-administered survey were implemented with their consent. Results : The findings of the study were as follows: 1. 60 percent of the dental hygienists investigated replied that they had occupation-related physical symptoms. By the length of service, the dental hygienists who worked for six to 10 years had the most symptoms. 2. Out of the occupation-related symptoms, the most prevalent symptom was a pain in the shoulders and neck(41%), followed by a pain in the lower back, a pain in the legs, a pain in the wrists and skin diseases. The most painful parts of the body were hands and arms. 3. In regard to the relationship between the general characteristics and the intensity of pain, the highest group of the dental hygienists in Seoul replied that they had a severe pain, and the lowest number of those in the large cities gave the same answer. 4. Concerning the cause of occupational diseases, 65.7 percent cited the wrong posture. 5. As to relationship between the general characteristics and regular hospital-visit experiences for the prevention of pain during work hours, many of the dental hygienists who were in their 40s and 50s visited hospitals from time to time, and many of those in their 20s never did that. 6. In regard to links between the general characteristics and an opinion on the necessity of regular education, many of the respondents from Seoul and urban regions involving large cities considered it necessary to receive education on a regular basis. By daily work hours, the highest number of those who worked for eight hours or less considered that necessary, and lots of those who worked for 11 hours didn't consent to that. The gaps between them were statistically significant(p<0.05). Conclusions : Given the findings of the study, daily work hours and length of service were two integral factors to affect the regular hospital-visit experiences and pain, and the wrong posture was identified as the most common cause of occupational diseases. To ensure the successful prevention of occupational diseases, dental hygiene students should be taught the importance of occupational disease before they start to work, and supplementary education should be provided for dental hygienists to work in the right posture.

  • 쇼핑몰들의 상품 정보를 효과적으로 비교할 수 있는 비교 쇼핑(comparison shopping) 시스템에서 사용자가 찾고자하는 상품에 대한 정확한 지식이 없이 검색할 경우, 불필요한 검색 결과로 인해 시스템의 효용성을 떨어지고, 사용자는 많은 시간을 소비하게 된다. 이러한 문제를 해결하기 위해서 시맨틱 웹 기반의 이미지 검색을 이용한 비교 쇼핑 시스템(Comparison Shopping Systems using Image Retrieval based on Semantic Web)을 제안한다. 제안된 시스템에서는 각 쇼핑몰들의 상품 이미지들을 온톨로지(Ontology) 기반으로 주석(annotation)처리한 후, 주석처리 된 이미지들을 통해 쇼핑몰을 구축하게 된다. 사용자는 이렇게 생성된 쇼핑몰에서 복잡한 키워드 검색을 이미지 검색으로 대체하여, 자신의 요구사항을 반영하고, 보다 정확한 검색을 할 수 있게 된다. 제안된 시스템의 성능평가를 위해 기존의 키워드 검색 기반 시스템과 단순 시맨틱 웹 기반의 비교 쇼핑 시스템의 성능을 비교 평가하였다. 그 결과, 시맨틱 웹 기반의 이미지 검색을 이용한 비교쇼핑 시스템이 키워드 검색기반과 시맨틱 웹 기반의 비교 쇼핑 시스템보다 평균적으로 50%, 20% 향상된 성능을 보였다.
