  • 그람 음성균의 감염에 의한 만성 염증질환인 치주염이 동맥경화를 동반한 허혈성 심장질환 (협심증이나 심근 경색)을 일으킬 수 있는 위험인자로 작용할 수 있다는 보고가 있었다. 그러나, 그 기전에 관해서는 명확하게 알려져 있지 않다. 작용기전의 하나로서, 치주염에 의해 치주조직에서 국소적으로 생긴 염증성 싸이토카인(IL-1${\beta}$, IL-6, $PGE_2$, TNF-${\alpha}$)이 혈행을 따라 이동하여 심혈관에서 동맥경화를 일으킬 수 있다는 가설이 제시되고 있는데, 이 가설을 검증해 보고자 한다. 서울대학교 병원 순환기 내과에 불안정 협심증이나 심근경색으로 입원한 환자 및 과거 이 질환의 병력을 갖고 있거나 검진 목적으로 내원하여 관상동맥 조형술을 받은 환자들 중 동맥경화로 진단받은 사람을 실험군(24명)으로 하고, 동맥경화로 진단받지 않은 사람을 대조군(12명)으로 하였다. 치주질환의 활성도를 나타내는 치은 지수, 치태 지수, 치주낭 깊이, 부착 상실을 측정하였다. Paper strip을 실험대상 치아(Ramfjord's teeth)들 중에서 가장 깊은 치주낭을 가진 두 개의 치아를 택하여 각 치아의 가장 깊은 치주낭에 30초간 삽입한 후 밀폐된 plastic tube에 넣고 ELISA kit를 이용하여 IL-1${\beta}$, IL-6, TNF-${\alpha}$, $PGE_2$의 농도를 측정하였다. 환자의 plasma에서도 동일한 싸이토카인의 농도를 측정하였다. 설문조사를 통해 동맥경화의 위험 인자로 간주되어온 고혈압, 당뇨, 가족력, 심근경색이나 협심증의 기왕력, 흡연의 유무를 기록하였다. 혈액검사를 하여 total cholesterol, triglycerides, LDL cholesterol, HDL cholesterol, WBC, CRP (C-reactive protein)의 농도를 측정하였다. 치주조직에 대한 임상 검사 결과 치은의 염증상태를 나타나는 지표인 치은 지수에서만 실험군이 대조군에 비해 유의할 정도 (p=0.0174)로 높게 나타났고, 만성적인 염증의 결과로 인한 치조골의 사실 정도를 나타내는 치주낭 깊이나 부착 상실에서는 유의할 만한 차이를 보이지 않았다. 치주낭에서 측정한 염증성 싸이토카인 중 IL-1${\beta}$, $PGE_2$가 실험군에서 유의할 만한 차이 (p=0.005, 0.022)를 보이며, 더 높은 농도로 나타났고, TNF-${\alpha}$는 대조군에서 유의성 있게 (p=0.009) 높게 나타났다. 그러나, plasma의 싸이토카인이나, serum lipid/lipoprotein, C-reactive Protein, WBC는 유의할 만한 차이를 보이지 않았다. 또한 치은열구액내의 싸이토카인과 이에 상흥하는 싸이토카인 간에 상관관계는 관찰되지 않았다. 다변량 로지스틱 회귀분석 결과, 치은열구액내의 IL-1${\beta}$와 TNF-${\alpha}$ 만이 동맥경화와 유의성 있는 관련성을 보였고, 특히 IL-1${\beta}$와 교차비는 273으로 상당한 관련성을 보여주었다. 결론적으로, 치주조직에서 국소적으로 생긴 염증성 싸이토카인이 그대로 혈행으로 이동하여 혈장내의 싸이토카인 농도를 높이는 것은 아니다. 그러나, 치주염으로 인해 치은열구내액내에 국소적으로 증가된 염증성 싸이토카인은 동맥경화와 상당한 관련성을 가진다.

  • The purpose of this study was to examine the use of dentifrice among children in a bid to provide information on dentifrice including its function to children's parents, the major consumers of dentifrice for child. And it's additionally meant to offer useful information on the production of toothpaste for kid. The subjects in this study were parents with children, who dwelled in Seoul and Gyeonggi province. After a self-administered survey was conducted for about three months from May to July 2007 to gather data on their use of dentifrice for child, a comparative analysis was implemented. The findings of the study were as follows: 1. Concerning the state of the use of their children's dentifrice, the largest number of the children(58.1%) started to use toothpaste at the age of one or down, and the most common first toothpaste they used was dentifrice for preschooler(86.8%). As for whether to use fluoride-containing toothpaste, the largest group of the parents(58.1%) gave an affirmative answer. Regarding the form of the toothpaste in use, the majority of their children used toothpaste of cream type(86.2%). The greatest group of the children used the amount of toothpaste that was as large as the three-tenths or four-tenths of the bristles(35.9%). 2. As for the state of the use of dentifrice for kid, the greatest group used that kind of toothpaste(81.4%). In the event of those who didn't use it, the last time when their children used toothpaste for kid was when they were at the western age of 3(33.9%) and 4(33.9%). Concerning the reason why they replaced toothpaste for kid with one for adult, the largest group of the parents did that on their own judgment(58.1%). As to the right time for replacing toothpaste for kid by one for adult, the greatest group considered it advisable for children to start using toothpaste for adult at the western age of 4 or 5(43.2%). 3. In relation to the state of the purchase of toothpaste for their children, the largest group was under the moderate influence of the children when they bought it(45.2%). The greatest group attached importance to the ingredients of toothpaste(41.6%), and the most preferred ingredient was fluoride(56.3%). 53.0 percent took consideration on the content of ingredients or the instructions. 4. In regard to priorities for the choice of toothpaste for their children, they gave top priority to brand(16.7%), followed by quality(14.6%) and ingredients(13.5%). The age of the parents made a statistically significant difference to the children's age when they started using toothpaste, and how they started to do that and whether they used fluoride-containing toothpaste were statistically significantly different according to that as well(p < 0.01). In regard to the impact of the occupation of the parents, the use of fluoride-containing toothpaste was more common among the stay-at-home mothers(p < 0.01).

  • This research was conducted to evaluate the operational performance of landfill facility and landfill gas energy facility from the questionnaire survey. In order to evaluate overall operational performance, three types of weighting methods were applied to each technical, economical, and environmental item. There was no significant difference between an equal weighted method, a weighted method of 40% for technology, 30% for economy, and 30% for environment, and a weighted method of 30% for technology, 40% for economy, and 30% for environment. In technical performance, large and middle scales of landfill facilities showed higher scores of 14.8 ~ 19.7 and 14.3 ~ 19.0 than 9.8 ~ 13.0 of small scale one. In environmental performance, large, middle, and small scales of landfill facilities showed 21.3 ~ 23.7, 17.6 ~ 19.6, and 20.8 ~ 23.1 scores, respectively. However, in economical performance, there was significant difference between them with scale. Large and middle scales of landfill facilities showed higher scores of 22.0 ~ 29.3 and 20.5 ~ 27.3 than 6.0 ~ 8.0 of small scale one. As a result of evaluation for landfill gas energy facility, large scale facility showed 19.2 ~ 25.6 and 17.8 ~ 23.7 scores in technical performance and 23.1 ~ 25.7 and 21.3 ~ 23.7 scores in environmental performance, respectively. However, in economical performance evaluation, large scale of landfill gas energy facility showed relatively higher of 27.8 ~ 33.3 score than 18.8 ~ 25.1 of small scale one. From these results, it was shown that economy evaluation heavily effect on the operational performance of landfill facility and landfill gas energy facility compared to technology and environment evaluation.

  • The purpose of this study was to assess the relationship that adolescent stress perception level has with dietary habits and oral health behaviors in high school students. A survey of high school students in some areas of the Jeollabuk-do province of South Korea was conducted. Five hundred fourteen survey responses were used in the final analysis. As a result of the questionnaire survey, the following conclusions were obtained. The highest stress type was indicated to be academic stress (mean${\pm}$standard deviation [SD], $3.09{\pm}0.89$). The next was shown to be home (family) stress (mean${\pm}$SD, $2.85{\pm}0.84$). The possibility of using a dental clinic was indicated to be less in girls than boys (p<0.001). Regarding subjective oral health behavior, the possibility of visiting a dental clinic was low in those who thought that their own oral health condition was not good or moderate (p<0.05). Also, it was shown that the higher stress led to the higher possibility of visiting a dental clinic (p<0.01). Students with higher grades had a in the upper ranks were indicated to have high possibility of having a regular meal (p<0.01). Higher stress led to the significantly higher possibility of eating cariogenic food (p<0.01). Students with median grades had a high possibility of eating cariogenic food (p<0.01), while students with higher grades had a low possibility of eating cariogenic food (p<0.05). These resultss show that stress perception level influences dietary habits and oral health behaviors. Thus, there is a need to develop a program in high scholls to promote the physical and mental health of students to relieve stress. Substantial and systematic oral health education is thought to be likely needed to develop desirable dietary habits.

  • The high dental treatment cost has been considered as one of the major reasons for inappropriate dental treatment in Korea. The aim of this study was to investigate the opinions of expansion of National Health Insurance (NHI) in dental treatment fields not covered with NHI and buying private dental insurance. This survey was carried out targeting 266 adults from their 30s to 50s with convenience sampling. The higher orders in stress of dental treatment cost were orthodontic treatment, dental implant, prosthodontic treatment, and caries treatment not covered with NHI. The higher orders in needs of expansion of NHI were caries treatment not covered with NHI, prosthodontic treatment, and orthodontic treatment. The agreement percentages with age restriction in NHI were scaling 57.1%, denture 23.3%, implant 14.3%, respectively. The subjective oral health had impact on the stress of dental treamtent cost and expansion on NHI. Although only 8.3% subjects had private dental insurance, 68.4% of the subjects had positive opinions buying private dental insurance. The correlation coefficients between stress of dental treatment cost and buying private dental insurance were implant 0.408, caries treatment not covered with NHI 0.404, denture 0.394, crown and bridge 0.375, and orthodontic treatment 0.313. Expansion of NHI in dental treatment and development of private dental insurance was suggested to treat dental disease in appropriate time.

  • This study was conducted to develop a plan for emotional labor of clinical dental hygienists by understanding the factors affecting their emotional labor. Self-administered questionnaires were distributed to 293 dental hygienists who worked in dental hospitals and clinics located in Busan and Gyeongsangnam-do from June to September in 2013. The questionnaire items used in this study consisted of 5 items of general characteristics, 2 items of characteristics related to turnover, and 9 items of emotional labor. t-test, ANOVA, and multiple regression analysis were performed using the SPSS Statistics ver. 17.0 for Windows program for data analysis. The average level of the study subjects was $69.85{\pm}12.82$. With regard to the emotional labor according to the general characteristics, the frequency of emotional expressions (p<0.037) showed significant differences in the marital status. The workplace showed significant differences in the frequency of emotional expressions (p<0.001), attentiveness of emotional expressions (p<0.002), emotional dissonance (p<0.032), and total (p<0.001). The turnover intentions showed significant differences in the frequency of emotional expressions (p<0.001), attentiveness of emotional expressions (p<0.001), emotional dissonance (p<0.001), and total (p<0.001). As a factor affecting emotional labor, turnover intention (p<0.001) and workplace (p<0.001) had an effect on emotional labor. The results showed that turnover intention and workplace were associated with the emotional labor of dental hygienists. There is a need to develop an emotional education program to make it possible to effectively manage emotional labor of dental hygienists for providing high-quality medical services of dental institutions.

  • The purpose of this study was to investigate the differences in health belief related to vaccination among dental hygiene students, identify the factors affecting hepatitis B vaccination, and provide basic data for health education concerning hepatitis B prevention. Hepatitis B vaccination was positively correlated (r=0.179, p=0.003) with seriousness of believing that hepatitis B would affect psychological, physical, and social activities and negative correlation (r=-0.183, p=0.002) was also found between perceived barriers related to hepatitis B. As for the factors affecting hepatitis B vaccination, juniors were 0.39 times (95% confidence interval [CI]=0.21, 0.71) more likely to have it affected than seniors and those who were more serious, and who had greater barriers were more likely to have it affected-1.80 times (95% CI=1.29, 2.52), 0.61 times (95% CI=0.41, 0.90) respectively (p<0.05). It is therefore urgent to develop a program within a curriculum that can begin with freshmen along with specific education with the objective of obliging dental hygiene students to receive hepatitis B vaccination. It is also necessary to provide consecutive sessions of education rather than one-time education and to develop a specific plan for obligatory hepatitis B vaccination through correct and thorough education.

  • The purpose of this study was to examine the impact of the oral health status and health care of elderly people on their self-rated health(SRH). The subjects on this study were 479 senior citizens who were at the age of 65 and up and resided in the city of Busan. They got a dental checkup, and a survey was conducted by having an one-on-one interview. After the collected data were analyzed, the following findings were given: The senior citizens were diagnosed with a mean of 1.43 systemic diseases, and hypertension(51.8%) was the most prevalent disease among them, followed by diabetes(25.1%), arthritis(41.8%), oral diseases(75.6%), stroke(9.0%) and heart diseases(15.9%). Their self-rated health was better when they were male, when they were aged between 65 and 69, when there was someone with whom they lived, when they were better educated and when they owned their own houses. But their self-rated health was poorer when they felt more oral symptoms, when they had more missing teeth and when they needed both of maxillary and mandibular dentures. Their self-rated health was more positively affected when they were better educated($\beta$=0.894), when they owned their own houses($\beta$=4.220), when they got a dental checkup on a regular basis($\beta$=2.997) and when the rate of their functional tooth was larger($\beta$=0.081). And that was more negatively influenced when they had a denture($\beta$=-1.110), when they had more oral symptoms($\beta$=-1.590) and when they had more systemic diseases($\beta$=3.363). There is a close relationship between the oral health and self-rated health of elderly people. Therefore how to promote their oral health should carefully be considered.

  • With about 75% of the population of Korea criticizing the government's disaster policy and a failure to respond to large-scale emergency like the Sewol ferry sinking means that there is a deep distrust in the government. In order to prevent dreadful disasters such as the Sewol ferry sinking, it is important to secure a prime time with respect to disaster safety. Improving crisis management skills and managerial role of police officers who are in close proximity to the people is necessary for the success of disaster management. With disaster management as one of the most essential missions of the police, as a part of a national crisis management, a step by step strengthening of the disaster safety management system of the police is necessary, as below. First, at the prevention phase, law enforcement officers were not injected into for profit large-scale assemblies or events, but in the future the involvement, injection should be based on the level of potential risk, rather than profitability. In the past and now, the priortiy was the priority was on traffic flow, traffic communication, however, the paradigm of traffic policy should be changed to a safety-centered policy. To prevent large-scale accidents, police investigators should root out improper routines and illegal construction subcontracting. The police (intelligence) should strengthen efforts to collect intelligence under the subject of "safety". Second, with respect to the preparatory phase, on a survey of police officers, the result showed that 72% of police officers responded that safety management was not related to the job descriptions of the police. This, along with other results, shows that the awareness of disaster safety must be adopted by, or rather changed in the police urgently. The training in disaster safety education should be strengthened. A network of experts (private, administrative, and police) in safety management should be established to take advantage of private resources with regard to crisis situtions. Third, with respect to the response phase, for rapid first responses to occur, a unified communication network should be established, and a real-time video information network should be adopted by the police and installed in the police situation room. Fourth, during the recovery phase, recovery teams should be injected, added and operated to minimize secondary damage.
