Objectives: The aim of this study was to assess how nutrient intakes are related to risk factors for metabolic syndrome according to dietary patterns in the middle-aged adults. Methods: The subjects (n = 187; 47 men, 140 women) consisted of middle-aged adults over 30 years old in Ilsan area. The metabolic syndrome was diagnosed according to the data collected from each subject, including anthropometric measurements and blood analyses. The dietary patterns were derived from the average of two-day dietary intake data. Results: Factor analysis identified three major dietary patterns which were "Meats and alcohol", "Mixed grains, vegetables and fruits", and "Rice, Kimchi and fish & shellfish". The daily intakes of energy, protein, and sodium increased across quartiles of "Meats and alcohol" pattern scores (p < 0.05), whereas the intakes of carbohydrates, potassium, calcium, and fiber increased across quartiles of "Mixed grains, vegetables and fruits" pattern scores (p < 0.001). The "Meats and alcohol" pattern scores were positively correlated with protein and sodium intakes but inversely correlated with carbohydrates, fiber and potassium intakes which were adjusted for age, sex and energy (p < 0.05). The highest quartile pattern score of "Meats and alcohol" pattern had elevated odds ratio of abdominal obesity and metabolic syndrome (p < 0.05). The risk of hypertriglyceridemia decreased in the highest quartile of "Mixed grains, vegetables and fruits" pattern (OR 0.35, 95% CI 0.12-1.00). Conclusions: Our results suggested that reducing the consumption of meat and alcohol along with increasing fruits, vegetables and mixed grains would be helpful for preventing the metabolic syndrome and chronic diseases.

Purpose: Terminal cancer influences on patients as well as their family members. This research was performed to evaluate the quality of lift of primary family caregivers and to investigate the influencing factors. Methods: The results of survey were collected from 81 family caregivers who were taking care of hospitalized terminal cancer patients at an oncology department of university hospital in Daejeon from March 2005 to January 2006 with questionnaires. The questionnaires were consisted of the general characteristics of the subjects, and 36-items short-form Health Survey (SE-36) Korean version to evaluate the quality of life of family caregivers, the characteristics of patients and family caregivers' caring trait. Results: Family caregivers' mean (${\pm}SD$) SF-36 score was 47.9 (${\pm}20.7$). Influential factors on family caregivers' life quality were daily raring hours, economic burden, type of treatment; only supportive care, caring duration, sex, the numbers of ADLs (activity of daily livings) items that patients needed help in order by stepwised multiple logistic regression analysis (overall $R^2=0.639$, P=0.044). Conclusion: Daily raring hours and economic burden were two influential modifiable factors on family caregivers' quality of life. Therefore, social supportive systems are required to reduce family caregivers' daily caring hour and economic burden.

This study was carried out to survey the degree of the recognition and necessity of wedding food to include $Ph{\grave{a}}ebak$ and Ibaji foods prepared by bride's parents and sent to the bridgroom's. The participants of the survey were 293 housewives of 20 years old or more residing in Seoul area. The questionnaires used in this research consisted of 10 questions. The findings could be summarized as follows: 1. As to the degree of the recognition of $Ph{\grave{a}}ebak$ food, 55.2 percent of the participants perceive it as 'the food sent to the bridegroomvs house to be used when the newly-weds greet groom's relatives, whereas 35.8 percent regarded the practice as 'a traditional custom from the ancient times,' which is, in fact, correct and exact. As to its importance, 10.2 percent regarded $Ph{\grave{a}}ebak$ food very important, while 48.5 percent, 'important,' and 11.9 percent, 'not important.' 2. As for the items for $Ph{\grave{a}}ebak$ dishes, 77.5 percent answered their preferences for 'jujube prop-nut,' followed by 'ricecake,' 'liquor' and 'Korean cookies,' in descending order. 3. As for the meaning of Ibaji dishes, 48.2% understand them as 'a set of dishes prepared by the bride's parents to be sent to the bridegroom's'; and as for their willingness or necessity of sending the Ibaji dishes, 15.5 percent indicated that they might prepare them, whereas 78.7 percent said that they would prepare them if the situation required. On the other hand 5.8 percent did not feel the necessity. The overall result is that most females surveyed recognized the two types of food important and were inclined to prepare them when the occasion demanded.

This paper presents the optimum dimension of 89 ton class stow-net vessel with stern-fishing. The model of basic design is developed by using the optimization techniques referring to objective function and numerous constraints as follows; speed, fishing quantity, fishing days, catch per unit effort(CPUE), and weight/ratio of main dimensions, etc. Thus, the basic design of stow-net fishing vessel is built up by using the optimization of the design variables called the economic optimization criteria, and the objective function represents the criterion which is cost benefit ratio(CBR). The main conclusions are as follows. 1. S/W for decision of optimum hull size is developed in 89 ton class stow-net fishing vessel which is constructed with optimization of the design variables called the economic optimization criteria. 2. For optimum ship dimensions in 89 ton class stow-net fishing vessel, the hull dimensions can be obtained in the range of L= 27.3m, B = 6.6m, D = 2.80m, Cb = 0.695, T/D = 0.80, $\Delta$(displacement)=281.7ton with 10 knots.

Maternal stress was one of the common symptoms that pregnant women could have experienced during pregnant period. The purpose of this study was to investigate the relation of maternal stress with maternal nutrients intake and pregnancy outcome. Subjects were 248 pregnant women and were recruited at two hospitals in Seoul area. Individual stress levels were divided by the stress scores (total 41 scores), as low stressed group (< 12) and high stressed group (${\geqq}12$). The social characteristics, nutrient intake, anthropometric measurements and pregnancy outcome were compared between low stressed group (LSG) and high stressed group (HSG) to recognize risk factor of maternal stress. We found that subjects experience stress by various factors which were concern about newborn (40.4%), concern about health (28.8%), economic difficulties (13.2%), depress (10.1%), family relationship (2.9%), concern of house work (2.5%), human relationship (2%). In HSG, unemployed rate (p < 0.05) and pre-pregnancy BMI (p < 0.05) were higher than in LSG. Family size in HSG was larger than that in LSG (p < 0.01). Doing regular exercise with the light activity level was significantly higher in LSG (p < 0.05). The nutrient intake in LSG was slightly higher than that in HSG, but not statistically significant. Pregnancy outcome was not significantly affected by the maternal stress. In conclusion, the risk of maternal stress may be related with a life style during pregnancy. Therefore, life style for maternal stress control, such as weight control and regular exercise is recommended to prevent maternal stress.

The risks of sanitary indicative bacteria, heavy metals and chlorinated derivatives in 94 cases of sanitary wet towels used in food services (39 from sanitary wet towel treatment business, 55 from food services) were assessed in the present study. Lead was detected in the range of N.D.~0.41 mg/kg (75 cases were not detected), N.D.~0.25 mg/kg of arsenic (93 cases were not detected), N.D.~0.01 mg/kg of cadmium (7 cases were lower than limit of quantitation; 87 cases were not detected), 0.003 mg/kg ~ 0.09 mg/kg of mercury. And chromium (VI) was not detected from all samples. The level of lead was the highest among the tested heavy metals, and the highest concentration of lead was 0.41 mg/kg. However, it was only 2.1% of legal limit (less than 20 mg/kg). The average moisture content of the samples was 61.9% (50.0% ~ 77.0%) and it showed no relevance to the detection of bacterial counts. Escherichia coli was not detected. Bacterial counts were detected 43 cases and among them, 24 cases were exceeded the legal limit. It was verified that the packaging conditions of sanitary wet towel (whether it is packed by a piece or not and sealed or not) are critical factors to cause the germ contamination and cross contamination in the wet towels. The chlorinated derivatives (chlorites and chlorates) were detected in 17 (19.3%) out of 88 cases. The results would be used as preliminary information to establish the programs of "Safety education for manufacturers and public policy of safety".

The purpose of this study was to examine the relationship between oral health habits and oral diseases in an attempt to raise awareness of the need for prolonged dental checkup projects and lay the foundation for oral health education and sustained oral health care projects. The subjects in this study were 2,643 workers from 76 workplaces in Siwha Industrial Complex in the city of Ansan, Gyeonggi province, who were at the age of 20 and up. The findings of the study were as follows: 1. Concerning the experience of visiting a dental clinic over the past year, 760 male workers (37.4%) and 237 females (38.9%) visited dental clinics in the past year. By age group, those who were in their 50s (54.0%) visited dental clinics the most, and the workers in their 30s (67.9%) paid a visit the least. The gap between the age groups was statistically significant (p < 0.001). 2. In regard to the time for toothbrushing by age group, the workers in their 20s (64.6%) made up the largest group that brushed their teeth before breakfast, and those who were in their 60s and up constituted the greatest group that did toothbrushing after breakfast. The workers in their 20s brushed their teeth the least, as the rates of the workers of this age group who did toothbrushing after breakfast and dinner respectively stood at 64.0 percent and 54.5 percent. The disparities between the age groups were statistically significant (p < 0.001). 3. As for scaling experience for the past year, 302(46.0%) out of the workers who got their teeth scaled in the past year had periodontal diseases, and 1,600(80.6%) out of those who didn't suffered from periodontal diseases. The gap between them was statistically significant (p < 0.001). 4. Regarding the relationship of subjective oral health state to dental caries among the workers without dental caries, the largest group that numbered 327(54.1%) considered themselves to be in good oral health. In the event of the workers with dental caries, the greatest group that numbered 708(75.5%) found themselves to have one or more carious tooth(teeth). The disparity between them was statistically significant (p < 0.001). 5. As for connections between dietary habits and dental caries, those who had dental caries (2.29) showed a greater preference for snack than the others who hadn't (2.21). The preference for snack made a bigger statistically significant difference to dental caries than the other dietary habits (p < 0.05).

The aim of this study was to examine the effectiveness of oral health promotion program in a group of 9~18-year-old children and adolescents living in four orphanages in Dong-gu, Daejeon. The program was based on oral disease prevention program including oral health education, fluoride application and scaling every six months. Oral health status of total 109 orphans was examined by one dentists who were trained in 2010 Korean National Oral Health Survey. Dental caries index, community periodontal index and modified patient hygiene performance index (M-PHP) were checked using dental unit chair. Child oral health impact profile (COHIP) and subjective oral health recognition survey were carried out. Compared with data of 2010 national sample, the mean of decayed, missing and filled teeth showed no difference between the subjects and test values, but the means of decayed teeth, decayed surface, toothbrushing frequency of the subjects showed to become worse with advancing years in spite of oral health promotion program. COHIP, subjective oral health status showed lower than test values, too. In M-PHP and Calculus index, the subjects showed better by periodic oral health education and scaling. We suggest that oral health promotion program for orphans include oral disease treatment program as well as preventive program to improve oral health of orphans efficiently. And, oral health promotion program has to be connected with psychological support for improving quality of life of orphans.
