A survey was conducted to investigate housewives' perception and consumption of Korean fermented foods marketed in Taejon. Most subjects know how to prepare Kimchi(seasoned and fermented vegetables), 65-67% can make Kochujang(fermented red pepper soybean paste), Toenjang(Korean style soysauce) and Jang-atchies(pickled basic side dishes), 56% can make Kuk-ganjang(Korean style coysauce), 45% can make Chonggukjang (fermented soybean) and 34% can make Jot-kals(salt-fermented fish products). With decreasing age(p<0.0001), not many other subjects could make other fermented foods besides Kimchi. The percentages of subjects buying fermented foods were 71.5% for Chin-ganjang(Japanese style soysauce), 51.7% Jot-kals, 27.1%Kochujang, 25.7% Chonggukjang, 20.1% Jang-atchies, 10.4% Toenjang, 5.9% Kuk-ganjang, and 3.8% Kimchi. the uounger in age, the higher the tendency to buy marketed Kimchies(p<0.05) and Kochujang(p<0.01). The resons for purchasing fermented foods were convenience (52.9%), lack of preparation knowledge(17.5%), lack of time for preparation(12.5%), and lack of space for food storage(8.2%). Subjects indicated that their reasons for mot buying were as follows : use of additives or unreliability with regard to manufacturing dates(45%), bad taste(21%), unsanitary treatment(16%) and to keep their indigenous taste(14%). They cosidered expiration dates, taste, crpteria and safety as the important standard in selecting marketed foods. Younger subjects insisted on the improvement of sanitary condition and partial change of taste to increase the consumption of fermented foods. However, older subjects thought it best to keep the taste original for more utilization of fermented foods.

This study was designed and undertaken to find out the degree of powerlessness, self-esteem and family support of elderly home residents and to determine the relationship between powerlessness, self-esteem and family support. The data were collected from October 1st to 20th, 1998. The subjects in this study were 271 elderly home residents over the age 60 living in Taejon city. The study tool for measuring powerlessness was developed by S.E.Chung(1998), the other for measuring self-esteem, was a self-esteem scale developed by Rosenberg, and the tool for measuring family support was developed by Choi(1983), Cobb(1976) and Kang(1984). Data were analysed for percentage, mean, t-test, ANOVA and Peason-correlation coefficients using the SPSS program. The results of this study were as follows ; 1. The degree of powerlessness, self-esteem and family support was scored avove the median. 2. The relationship between powerlessness and self-esteem revealed a no significant inverse correlation, but powerlessness and family support, showed a significant inverse correlation, and self-esteem and family support, registered a very statistically significant correlation. 3. The general characteristics showing the differences of the elderly' powerlessness were sex, one' s health of state compared to other elderly' and living expense load. These yielded statistically very significant results. 4. The general characteristics showing the differences of the elderly' self-esteem were sex, state of ownership of a house, age, religion, one's health of state compared to other elderly'. Among these, sex and state of ownership of a house revealed statistically very significant differences, also age, religion and one's health of state produced statistically significant differences. 5. The general characteristics showing the differences of the elderly' family support were sex, state of ownership of a house, having some diagnosed diseases or not and one's health of state compared to other elderly' health. These also showed statistically significant differences. In conclusion, the factors influencing the elderly' powerlessness, self-esteem and family support generally were age, sex, their economic independence and health of state(which included especially having a diagnosed disease). Also, the family support was needed to reduce their powerlessness and to have their self-esteem highly.

The purpose of the present study was to evaluate the relationship between the amount of cuspal deflection and linear polymerization shrinkage in resin composite and polyacid modified resin composite. For cuspal defelction and shrinkage measurement, Dyract AP, Compoglass F, Z100, Surefil, Pyramid, Synergy Compact, Heliomolar and Heliomolar HB were used. For measuring polymerization shrinkage, a custom made linometer (R&B, Daejon, Korea) was used. The amount of shrinkage among materials was compared using One-way ANOVA analysis and Tukey's test at the 95% of confidence level. For measuring cuspal deflection of teeth, standardized MOD cavities were prepared in extracted maxillary premolars. After a self-etching adhesive was applied, cavities were bulk filled with one of the filling materials.Fifteen teeth were used for each material. Cuspal deflection was measured by a custom made cuspal-deflection measuring device. One-way ANOVA analysis and Tukey's test were used to determine differences between the materials at the 95% of confidence level. Correlation of polymerization shrinkage and cuspal deflection were analyzed by regression analysis. The amount of polymerization shrinkage from least to greatest was Heliomolar, Surefil < Heliomolar HB < Z100, Synergy Compact < Dyract AP < Pyramid, Compoglass F (p < 0.05). The amount of cuspal deflection from least to greatest was Z100, Heliomolar, Heliomolar HB, Synergy Compact Surefil < Compoglass F < Pyramid, Dyract AP (p < 0.05). The amount of polymerization shrinkage and cuspal deflection showed a correlation (p < 0.001).

PURPOSE: The aim of this study was to determine the relationships between weather and calendar variables and the admission volume at the emergency center in Daejon city. PATIENTS AND METHODS: Daily patient volume from January to November 2003 was matched with calendar and weather variables. Calendar variables included season, day of the week, holidays, and the day after a holiday. Weather variables included daily maximum, minimum, and average temperatures and other factors such as snowfall and rainfall. RESULTS: The average daily admission volume was 282 +/- 54 persons (187~605), and the most highly significant calendar and weather variables related with admission volume were holidays and maximal temperature, respectively. A regression model was calculated as follows: the daily patient volume = 214 + 2 x (maximal temperature) + 113 x (holiday) + 26.8 x (day after a holiday). This equation could estimate about 62.6% of the daily patient volumes. CONCLUSION: This study suggests that the temperature and a holiday may influence the number of visiting patients. Thus, the staffing level should be set appropriately by considering the estimated patient volume.

The purpose of this study is to investigate the concentration of plasma choline of Korean and to clarify the relationship between plasma choline concentration and choline intake. Plasma choline concentration of 30 young adults (15 males, 15 females) aged 20 - 30 years living in Deajeon metropolitan city are analyzed and their dietary choline intake. Choline content of one day meal was directly analyzed with the use of enzymatic method. Plasma choline concentration from more than 12 hr fasting blood was analyzed by using HPLC-MS. Choline intakes of male subjects were in the range of 253.51 - 1724.14 mg and those of female subjects were in the range of 240.85 - 938.06 mg. Mean intakes of choline were 634.53+/-353.68 mg in male subjects and 473.99+/-183.76 mg in female subjects. Plasma choline concentration of total subjects was in the range of 5.08 - 14.01 micro mol/L. Mean plasma choline concentration was 9.19+/-2.05 micro mol/L in male subjects and 8.11+/-1.70 micro mol/L in female subjects. Plasma choline concentration did not show significant correlation with choline intake in male and total subjects, but showed positive correlation with choline intake in female subjects (p<0.05). This result shows that more studies on large scaled samples are needed.
