Objectives : This study was carried out with the aim of utilizing it as basic data in a plan for oral health promotion by analyzing oral-health awareness in high school students of some districts in our country, and by analyzing physical, mental and social influential factors in oral health, through using OHIP(Oral Health Impact Profile). Methods : It surveyed by carrying out self-administered questionnaire research targeting 536 boy & girl high school students in the 1st and the 2nd grade at 3 high schools in some districts of Gyeonggi Province. Results : 1. As for experience of having not visited dental clinic, a case of having not visited accounted for 32.5%. On the other hand, a case of having visited accounted for 67.5%. As for the appearance of oral health education, only 2.8% responded as saying of having experience. 97.2% responded as saying of having not taken oral health education. 2. As for oral health state perceived by oneself, the response as saying of 'thinking it to be healthy' and that 'there is something wrong' showed the distribution of 34.1% that is the same ratio. As for oral health interest, a case of having a little interest(58.4%) or of being so much interested(12.5%) showed 70.9%. A case of having no special interest(24.8%) or of having no interest at all(4.3%) showed the level of 29.1%.3. As for oral health knowledge, the toothbrushing knowledge was the highest with 4.54 marks out of 6-point perfection. The toothbrush knowledge(4-point perfection) showed low point with 2.05 marks. 4. By gender, a case of men was high in OHIP(Oral Health Impact Profile) for the functional restriction and physical pain. On the other hand, in the remaining sphere, women were indicated to be high in OHIP. The statistically significant difference was indicated in the spheres such as physical pain, psychological discomfort, a drop in psychological ability, a drop in social ability, and social separation. 5. According to oral health state perceived by oneself, a case of thinking it to be healthy was indicated to be high in OHIP for every sphere. A case of thinking it to have gum disease was indicated to be low in OHIP for every sphere. The statistically significant difference was indicated in every sphere except the sphere of functional restriction. 6. As for a factor of having influence upon OHIP according to oral health knowledge, it was indicated that the higher toothbrush knowledge leads to having more influence upon OHIP. Conclusions : It could be known that the oral health knowledge and OHIP are varied as well according to the oral health interest level. Also, the oral health education proper for subjects is not being performed. Even as for frequency of visiting the dentist, a regular visit is failing to be made. In consideration of these points, the diversified and effective educational program is likely considered to be necessarily developed and improved that subjects can have more interest in oral health.

90년대 이후 전 세계적으로 지식경영(Knowledge Management : KM)에 대한 관심이 고조되고 있다. 특히 기업의 시장가치 중 지식자산이 차지하는 비중이 높아짐에 따라 한국의 건설 분야도 90년대 중반부터 대기업을 중심으론 지식경영을 도입하고 있다. 그러나, 중소${\cdot}$전문건설업체의 경우에는 기업의 재무 및 조직적인 이유로 지식경영에 대한 이해와 정보화에 뒤쳐지고 있는 실정이다. 더욱이, 건설 분야에서 중소${\cdot}$전문건설업체가 차지하는 비중이 매우 높게 나타나기 때문에 이들의 기술 수준이 건설공사의 품질과 직결된다고 해도 과언이 아니다. 따라서, 본 논문에서는 회사의 가치와 경쟁력 향상을 위해서 중소${\cdot}$전문건설업체들의 여건에 적합한 지식경영 전략 즉, 지식경영 도입 방안을 제시하고자 한다.

Fat consumption has decreased since the 1950's in the United States, and coronary heart disease mortality rates have gradually declined as well. These changes might be associated with changes of attitudes due to increased information about the relationship between fat consumption and hear disease. The purpose of this study was to determine whether knowledge and attitudes concerning fat and foods high or low in fat had an impact on peoples' actual fat consumption. for this study, the data of fat consumption and knowledge/attitudes of people came from the 1989-1991 Continuing Survey of food Intakes by Individuals/Diet and Health Knowledge Survey (CSFII/DHKS), conducted by USDA. It was found that women 65 years ed older tried to avoid more fat and consume more vegetables than those aged 25-64 years ; in fact, the actual fit consumption of those over 65 years was lowest among all age categories. However, the elderly did not have as much nutrition knowledge as people aged 25-64 years. Attitudes concerning vegetables and health were a better predictor of fat consumption than those concerning fat itself. However, low-fat milk consumption was influenced by nutrition knowledge as well as attitudes about fat intake people with better knowledge and attitudes concerning fat intake consumed more low-fat milk. This could be resulted from the reason that low-fat milk is a good substitute for whole milk. The conclusion of this study is that there are two essential elements in healthy eating patterns： a) good attitudes towards fat and vegetable consumption, and b) correct nutritional knowledge concerning the fat-content of foods and the availability of alternatives.

We present an axisymmetric model containing only one chimney to study how convection affects the flow in a steady state chimney. We find that the mass fraction of solid in a mush and the depth of a mush when the strength of convection is given. We use the knowledge of the variables in the mush to find the fluid flow in the chimney Our procedure employs the von $K{\acute{a}}rm{\acute{a}}n$-Pohlhausen technique for determining chimney flow and makes use of the fact that the radius of the chimney is much less than the thickness of the mush.

The purpose of this study was to examine the oral health care aware-ness of pregnant women and their actual oral health care in an effort to provide information on how to assist pregnant women to have the right knowledge on oral health and improve their oral health care. The subjects in this study were pregnant women who used obstetrics and gynecology hospitals or participated in pregnancy/child-rearing programs in the region of P. After a self-administered survey was conducted in July and August 2008, the following findings were given: 1. As for the best case of oral health care, the largest number(77.2%) of the pregnant women investigated brushed all the teeth, gums and tongue when they did toothbrushing. The smallest number of the women(6.8%) spent three minutes or more brushing their teeth. 2. As to dental treatment experience during pregnancy by age, 27.0 percent of the age 26-30 group had ever received dental treatment during pregnancy, which was higher than the rates of the other age groups with the same experience. 3. Regarding the necessity of oral health education geared toward pregnant women, 94.1 percent of the age 26-30 group and 96.3 percent of the group of age 31 and up felt the need for that, which were significantly higher than 72.7 percent of the age 20-25 group who agreed to the necessity of that education. 4. As to connections between oral health status and oral health care, the women who were in good oral health got 6.60 on oral health care. They scored significantly higher than those who were in a moderate state of oral health and who were in bad oral health, as the latter two groups respectively got 5. There was a significant correlation between oral health state and oral health care and between oral health knowledge and oral health care. The better oral health status led to better oral health knowledge, and the better oral health knowledge was followed by better oral health care. 6. As for factors affecting oral health care, oral health knowledge had the largest impact on that, followed by age, oral health status, experience of receiving oral health education for pregnant woman, dental treatment experience during pregnancy, monthly income and stress caused by oral diseases. Given the findings of the study, oral health education should be provided in light of the special physical and mental state of pregnant women. They should be encouraged to receive possible dental treatment during pregnancy if necessary, and they should learn about how to cope with a dental disease in case of develop it.

Background: Insufficient training in infection control and occupational health among healthcare workers (HCWs) in countries with high human immunodeficiency virus (HIV) and tuberculosis (TB) burdens requires attention. We examined the effectiveness of a 1-year Certificate Program in Occupational Health and Infection Control conducted in Free State Province, South Africa in an international partnership to empower HCWs to become change agents to promote workplace-based HIV and TB prevention. Methods: Questionnaires assessing reactions to the program and Knowledge, Attitudes, Skills, and Practices were collected pre-, mid-, and postprogram. Individual interviews, group project evaluations, and participant observation were also conducted. Quantitative data were analyzed using Wilcoxon signed-rank test. Qualitative data were thematically coded and analyzed using the Kirkpatrick framework. Results: Participants recruited (n = 32) were mostly female (81%) and nurses (56%). Pre-to-post-program mean scores improved in knowledge (+12%, p = 0.002) and skills/practices (+14%, p = 0.002). Preprogram attitude scores were high but did not change. Participants felt empowered and demonstrated attitudinal improvements regarding HIV, TB, infection control, and occupational health. Successful projects were indeed implemented. However, participants encountered considerable difficulties in trying to sustain improvement, due largely to lack of pre-existing knowledge and experience, combined with inadequate staffing and insufficient management support. Conclusion: Training is essential to strengthen HCWs' occupational health and infection control knowledge, attitudes, skills, and practices, and workplace-based training programs such as this can yield impressive results. However, the considerable mentorship resources required for such programs and the substantial infrastructural supports needed for implementation and sustainability of improvements in settings without pre-existing experience in such endeavors should not be underestimated.

Purpose: This study was to identify the relationship between knowledge, self efficacy, and self care behavior regarding foot care among elderly diabetes mellitus (DM) patients. Methods: The subjects consisted of 146 elderly with DM. The data collected from February to October 2008 were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression. Results: The mean scores of knowledge ($13.21{\pm}1.99$), self efficacy ($2.23{\pm}0.54$), and self care behavior ($2.29{\pm}0.51$) regarding foot care were moderate. The level of knowledge was significantly different according to education about DM (p = .012) and drinking (p = .007). Self efficacy was significantly different according to gender (p = .019), educational level (p = .014), spouse (p = .048), disease period (p = .000), admission of DM (p = .000), complication of DM (p = .001), education of DM (p = .023). Self care behavior was significantly different according to educational state (p = .003), disease period (p = .039), and other disease (p = .000). Significant correlations were found between knowledge and self care behavior (p = .001), self efficacy and self care behavior (p = .000), knowledge and self efficacy(p=.012). Knowledge and self efficacy were a predictor of self care behavior (18.2%). Conclusion: These findings indicate that perceived knowledge and self efficacy may be necessities to improve self care behavior regarding foot care among elderly DM patients. The above mentioned results will be reflected in developing patient educational programs.
