Purpose: It is to survey old men's utilization status of dental clinic and temporary-binding dentures and then to provide basic data to make a program for manufacturing old men's dentures and their teeth health education. Methods: Random selection was made on old men living in Daejeon and Chungnam, and a survey was conducted from April 15 to May 20, 2011. 500 questionnaires were distributed and 420 questionnaires were collected. Using spss 18.0 program, final analysis was made on 363 questionnaires except for 57 questionnaires which had missing value or showed some doubts about the unreliability. Results: 1. With respect to number of natural teeth as per the age, the upper/lower jaws had meaningful differences (P<.001), which means that the older the person is, the smaller number of natural teeth is. In the meantime, there was no meaningful difference according to sex. 2. With respect to kind of prosthetics installed in a mouth as per the age, there was meaningful difference in the upper jaws (P<.05) but there was no meaningful difference in the lower jaws. It was found out that the older the persons are, the more they use removable dentures while the younger the persons are, the more they use fixed partial dentures. 3. With respect to mouth health condition recognized by oneself, it showed bad (44.4%) and good (10.3%),which means recognition as bad is greater, and the age when prosthetics were first used is dispersed variously from below 40 to over 70. 4. Dental care institutions which they mainly used are hospital and clinics (91.5%), and 66.4% of them visited dental clinics lately. Preferential treatment if they go to dentists is as follows in the order of prosthetics (33.9%), gum treatment (24.2%) and pain treatment (14.9%). 5. 68.4% of them revisited dentists after installation of dentures and the reason for revisit is as follows in the order of poorly fitted dentures (35.1%), painful gum 25.9%, regular check-up 25.4% and difficult chewing 9.6%. Conclusion: As our country enters into an aging society, mouth health problem of old men has come to a serious issue, and therefore, a survey was conducted on some old men with respect to their utilization status of dental clinic and removable dentures in order to provide basic data for improvement of quality of their life, maintenance and enhancement of their mouth health. The study result shows that the older they are, the higher the loss rate of teeth as well as needs for prosthetics are, and thus it is thought the study will help to develop mouth health education program which may improve quality of old men's life by recovery of mouth functions declined due to loss of teeth and by regular check-up, education for mouth health control and following-up control of dentures.

Purpose: This study conducted a survey on the elderly of 65 years and over with physical debilities and ones capable of living at home residing in Jeju Special Self-Government Province to compare and analyze demo-sociological characteristics and factors influencing on oral health related living quality. And also this study intended to provide basic data for developing effective public medical policies and health promotion programs to increase oral health related living quality of the elder. Methods: The elderly of 65 years and over living in Jeju Special Self-Government Province were interviewed individually from 7 February 2011 to 18 April and interview results of a total of 220 subjects were analysed for this study. Results: Current status of the elderly including ones with & without physical debilities influenced functional limitation and behavioral aspects of GOHAI criteria used in this study. The elderly with physical debilities experienced less limitation in food chewing and swallowing, and pronunciation than ones capable of living at home. On the analogy of the previous study(by Park, N. G., 2010) in which oral health related quality and satisfaction of life of the elderly with physical debilities were different due to their physical, circumstantial and psychological limitations, the former's oral health conditions are worse than the ones capable of living at home and because of medical care accessability limitation they suffer from deteriorated oral condition. By the comparison of factors influencing on the living quality relating to the oral health of the elderly with physical debilities and ones capable of living at home, 2 factors, age and living area, were meaningful factors commonly influencing on the oral health related living qualities of both. The elderly of 75 years and over were more affected by psychological and behavioral aspects of oral health related living quality than the ones of 65-74 years, and the ones living in country suffered from functional limitations, pains and discomfort more than ones in city. Additionally, being different from the elderly capable of living at home, the ones with physical debilities were influenced by the factors of average monthly income and medical security type. Conclusion: Improvement of programs and systems to increase oral health related quality of life needs to be carried out preferentially for the elderly of 75 years and over, and dwelling in country. Also this study suggests that the policy of paying the denture insurance allowance in 2012 need effective planning considering the elderly's current status, age, living area, medical security type.

This study examined the oral health-related quality of life of the elderly using the oral health index and dental prosthesis status, and explored methods to improve the oral health status. The data collected from 'The fifth Korean national health and nutrition examination survey 2010' were analyzed. The subjects were 2273 elderly people, aged 65 years or older, who had completed an oral examination, health questionnaires and nutrition examination. Statistical analysis was done using the SPSS 22.0 for Windows. Frequency analysis, multiple regression analysis and structural equation model were used for statistical analysis. The general characteristics, oral health index and dental prosthesis showed differences in the subjective oral health status associated with as age, ST, FS-T, T-Health, maxillary crown needs, maxillary denture needs, mandibular denture needs, chewing status associated with the income level, FS-T, maxillary crown needs, maxillary denture needs, mandibular denture needs, speaking status associated with the ST, T-Health, maxillary implant status, and maxillary denture needs. In conclusion, both the oral health index and dental prosthesis needs affect the oral health related quality of life of the elderly. Governments should implement a variety of oral health programs and dental prosthesis policies to improve the quality of life related oral health of the elderly.

Demand for appropriate health care has gradually increased in Korea. In addition, developments of community- and school-based oral health programs have also focused oral health care for the oral health promotion. Especially, school-based oral health programs are the underpinnings of promoting oral health and preventing oral diseases among schoolchildren. School-based oral health programs have had three major components: oral health education, oral health services, and a healthful environments. These included oral health education(one-to-one communication, group communication, and use of mass communication), oral examination, fluoride mouthrinsing, pit-and-fissure sealants, fluoride gel application, mechanical plaque control, and chewing xylitol candy. In this study, we evaluate the effects of oral health programs among primary schoolchildren by comparing the oral health knowledge, oral health behaviors, and perception of caries prevention procedures. Data for this study were obtained from 699 primary schoolchildren at the two primary school in Daegu, Korea. One is experimental group, N primary school, that was established school-based oral health center under supervision of Nam-gu Public Health Center, the other is control group, N' primary school, that was yet to establish school-based oral health center. We surveyed children's oral health knowledge and behaviors, and perception of caries prevention procedures using self-administrated questionnaire and then analyzed differences of each item among two groups. The brief findings of this study were summarized as follows. There are several advantage to a comprehensive school-based oral health program. (1) School-based oral health programs facilitate and increase the effectiveness of teaching oral health subjects. (2) Schoolchildren are available for prevention or treatment procedure. (3) School-based oral health center may be less threating than private dental clinic. (4) With comprehensive school-based oral health programs the decayed, missing, and filled teeth(DMFT) of schoolchildren should demonstrate a substantial and steady decrease over time(Choi et al, 2004). In conclusion, treatment is not the answer to solving children's oral health programs; rather primary prevention is the key. Many countries and communities are focusing on hoe millions of underprivileged children can be provided with health care. Schoolchildren gain the knowledge and behaviors to attain and maintain good oral health in schools. For these reasons, the role of school-based oral health center is not only important but also a necessity.

Objectives: Diazinon is an insecticide which acts as a contact stomach and respiratory poison, and used throughout the world to control a wide range of sucking and chewing insects and mites on a range of crops. In this study, the airborne diazinon levels were measured for farmers, pest control operaters, landscapers, and agricultural chemicals sellers, and an assessment of the health risk to the workers was presented. The exposure scenario was based on the route of inhalation and skin absorption. The "OSHA Method No. 62" was used to sample and measure the airborne diazinon levels. The skin wipe method was applied to measure the level of the diazinone exposure through the skin. For the determination of exposure scenario, the exposure factors were surveyed for the daily average inhalation rate and the exposure period and frequency and time of diazinone as well as the body weight and lifetime of the workers. The median values of exposure frequency and exposure time were selected after evaluating the validity of those. Methods: The highest level of the diazinon exposure in the air was $107.21ug/m^3$ in farmers, followed by $93.53ug/m^3$ in landscapers, at $31.40ug/m^3$ in pest control operators, and $1.04ug/m^3$ in agricultural chemical seller. The amount of skin absorption was the highest in farmers at 63.39 ug/day, followed by landscapers at 10.47 ng/day, pest control operaters at 4.26 ng/day, and agricultural chemicals sellers at 0.34 ng/day. The hazardous indices calculated using toxicological reference value were 2.79 for pest control operaters, 0.41 for landscapers, 0.07 for agricultural chemicals sellers, and 0.06 for farmers. Conclusions: While the farmers were exposed to the high levels of diazinon through the air and skin, the pest control operaters, landscapers and agricultural chemicals sellers have more the diazinon hazards than the farmer based on the risk assessment in this study.

Since the Korean apple industry needs to expand its export market in Southeast Asia, this study investigates the attributes of Korean apples affecting consumer preference in Indonesia, Malaysia, Singapore, and Thailand. Based on an Importance-Preference analysis, the results are summarized as follows. First, price is the most important determinant for purchasing Korean apples by Southeast Asian consumers, except in Malaysia. Second, managing the intrinsic(sweetness and chewing texture) and extrinsic(surface and color) factors needs to be well maintained. Third, the priority of the marketing factor(wrapping) should be lowered. Fourth, while the importance of extrinsic factors(shape and size) is low, satisfaction is high, so these factors need to be managed to avoid overkill. Overall, Korean apples should have their own merits with an appropriate proper price, while maintaining a high quality. The results of this paper may provide suitable strategies for promoting apple exports to Southeast Asia.

The purpose of the study was to investigate nutritional status of chronic obstructive pulmonary disease (COPD) patients and to find out the differences according to the stages of disease. From March to October, 2006, 41 stable male patients of mild to severe COPD patients were recruited from Seoul National University hospital. The patients' of body weight and fat free mass were assessed by bioelectrical impedance analysis. The nutritional status of the patients was also assessed by 3-day recall, index of nutritional quality (INQ), dietary diversity score (DDS), dietary variety score (DVS), food group index pattern and dietary quality index (DQI). The total of 41 patients were classified into three groups, stage I, stage II and stage III groups according to the classification of Global Initiative for Chronic Obstructive Lung Disease (GOLD) standard. The mean age of the patients in each stage were 67.2-66.9 years showing no significant difference. The ratio of $FEV_1$/FVC were $57.5{\pm}7.3$, $46.9{\pm}7.6$ and $38.2{\pm}6.8%$, respectively showing significant differences according to the stages of disease. The fat free mass of the stage II ($48.2{\pm}4.7kg$) and III ($47.3{\pm}4.5kg$) was significantly lower than that of stage I ($53.1{\pm}6.9kg$) patients. There were significant correlation of fat free mass with $FEV_{1}$, and BMI (body mass index) with $FEV_{1}$/FVC ratio (p < 0.05). COPD patients showed the diet-related clinical symptoms of anorexia, dyspnea, dyspepsia, and chewing difficulty. Daily intakes of calorie, K, vitamin $B_2$ and folate of the patients were very low ($83.8{\pm}20.7%$, $58.9{\pm}14.4%$, $70.7{\pm}19.6%$ and $74.4{\pm}10.2%$, respectively) however, they did not significantly different according to the stages of disease. Daily intake of calcium was significantly lower in the stage III patients (p < 0.05). The mean scores of dietary variety score was significantly lower in the stage III patients (p < 0.001). Dietary quality index of the patients were not different among the stages of disease and the scores indicated poor quality of diet. As a summary, we found that body fat free mass, regularity of exercise, frequency of having snacks and dietary variety score were significantly associated with the severity of chronic obstructive pulmonary disease.

The purpose of this study was to examine the impact of stress on the habits of temporomandibular disorder in college students. The subjects in this study were 396 male and female students who were in their first to fourth years at five different colleges located in Jeollabuk-do. The findings of the study were as follows: As for the degree of bad oral habits, "sleeping on one side" was the most common bad oral habit, followed by "enjoying caffeinated beverages," "resting the chin on the hand or a thing" and "chewing food in one side of the mouth only." As a result of analyzing their stress by general characteristics including gender, there were significant differences according to gender in stress about school life problems, one's own problems and economic difficulties, and only stress about one's own problems statistically significantly varied with academic year. When the correlation of the factors was analyzed, perceived stress about school life problems and one's own problems had a significant positive correlation with bad oral habit scores. When a multiple linear regression analysis was made to determine the influence of general characteristics and perceived stress on bad oral habit scores, gender, academic year, self-rated oral health status, stress about school life problems and stress about one's own problems were identified as significant variables. The findings of the study illustrated that there was an organic relationship between the bad oral habits and stress of the college students.

Objective: We investigated visual marbling level (VML) influence on pork loin physicochemical traits, consumer palatability responses, VML liking, purchase intent, and their relationships. Methods: For each of five slaughtering dates, at 24-h postmortem, nine paired Duroc castrated male boneless Longissimus dorsi (LD) muscles were categorized into low (LM, score 1 to 2, n = 3), medium (MM, score 3 to 4, n = 3), and high (HM, score 5 to 6, n = 3) VML. Meat physicochemical quality traits and consumer responses (n = 389) on palatability and VML liking, and purchase intent were evaluated. The experiment was in randomized complete block design. Analysis of variance, Duncan's multiple mean comparisons, and correlation coefficients were determined. Results: VML correspond to crude fat (r = 0.91, p<0.01), but both were reversely related to moisture content (r = -0.75 and -0.91, p<0.01, respectively). As VML increased, ash (p<0.05) and protein (p = 0.072) decreased, pH and $b^{\star}$ increased (p<0.05), but drip, cooking (p<0.05) and thawing (p = 0.088) losses decreased. Among treatments, muscle fiber diameter, sarcomere length, total and insoluble collagen contents, $L^{\star}$, and $a^{\star}$ did not differ (p>0.05). Compared to the others, HM had lower collagen solubility percentage (p<0.05), but similar (p>0.05) Warner-Bratzler shear force (WBSF). No differences (p>0.05) were found in juiciness, overall flavor, oiliness, and overall acceptability, but HM was more tender (p<0.05) than the others. Based on VML, consumers preferred MM to HM (p<0.05), while LM was similar to MM and HM (p>0.05). Corresponding to VML preference (r = 0.45, p<0.01), consumers (83%) would (p<0.01) definitely and probably buy MM, over LM (74%), and HM (68%), respectively. Conclusion: Increasing VML in pork LD altered its chemical composition, slightly increased pH, and improved water holding capacity, thereby improving its tenderness acceptability. Marbling might reduce chewing resistance, as lower collagen solubility in HM did not impact tenderness acceptability and WBSF. While HM was rated as most tender, consumers visually preferred and would purchase MM.
