This study conducted surveys on perception and utilization of Korean soybean paste targeting 493 women from their 20s to 60s residing in Daegu. Most subjects married (75.3%), were part of a nuclear family (84.8%), had more than a high school diploma (95.8%), had a career (47.9%), lived in an apartment (68.4%), had a total household income of 5 million won or more (38.1%), and had monthly food expenses more than 0.5 million won and less than 1 million won (42.2%). Regarding perception, 'rich nutrition' was the most commonly held perception in subjects in their 60s (4.4), followed by 'good taste' in subjects in their 40s (4.3). Regarding reasons for consumption 'healthy' was highest in subjects in their 60s (47.3%) and 40s (45.6%) and 'delicious' in subjects in their 20s (56.1%). Regarding how to make it, subjects in their 60s responded 'know for sure' (57.1%), while only 2% of 20s responded the same. Subjects in their 50s and 60s had a higher ratio of answering 'know' while 20s and 30s 'don't know', For preparation methods, subjects in their 20s (53.1%) and 30s (41.4%) answered 'buy at the market', subjects in their 40s (68.9%) 'get from family or relatives' and subjects in their 60s (47.3%) 'make by one's own'. For preservation method, subjects in their 20s and 30s answered 'preserve in refrigerator', the 60s tend to answer 'preserve in jangdokdae'. Buying at the market was most common in subjects in their 20s (36.1%) and 30s (28.5%) and the reason was 'convenient' (39.6%). The place of purchase was 'in large supermarket or department store' (78.5%). For the future consumption pattern, 'increase in consumption of commercialized product (44.0%)', subjects in their 60s answered 'keep making at home' while subjects in their 30s and 40s answered 'keep making at home or buying product half and half'. According to the above study results, women living in Daegu region were aware of excellence of traditional soybean paste. However, due to changes in residential circumstance and lack of knowledge about the recipe, they did not make. They receive soybean paste t from family, relatives or bought in the market, which indicates the continuous decrease in home-made soybean paste. Therefore, due to the expanding social participation of women, the product market is expected to increase. I think it is important to develop traditional commercial soybean paste in the traditional way to improve the traditional flavors.

The purpose of this study was to provide basic data for nutritional education for juveniles' desirable vegetable intake by analyzing their vegetable intake, dietary habit and nutrient intakes according to gender of middle school students in Chungnam. The average age of the subjects was 15.0, height was 162.5 cm, weight was 53.5 kg and their average BMI was $20.1kg/m^2$. The frequency of eating supper in girls was lower than that in boys. Many respondents answered that a meal-time was 10~20 minutes. Without gender difference, more than 90% respondents thought that vegetables were good for health. As for the preference of vegetable, subjects responded, "I am in the middle", "I like them", "I dislike them", "I like them very much", and "I dislike them very much" in order, without gender difference. The frequent eaten leaf vegetable was Chinese cabbage, the frequent eaten fruit vegetable was cucumber, and the frequent eaten root vegetable was radish. The favorite leaf vegetable was lettuce, the favorite fruit vegetable was corn, and the favorite root vegetable was sweet potato. The preference degrees of taro and ginger were very low. The reasons why they liked a vegetable were that it was delicious and they ate it at home often. In addition, the reason why they disliked vegetables was that they are untasty in flavor or texture and it showed that many students had a prejudice that vegetables were untasty. The intakes of plant protein, dietary fiber, ash and INQs of dietary fiber, calcium, vitamin C, folate, vitamin E in the group with high preference of vegetables were significantly higher than those of low preference group. The study results indicate that intake frequency and preference of root vegetables in juveniles are low and the major reasons of these results are taste and eating experience of vegetables. In addition, the intake amounts of dietary fiber and folate are poor in the subjects with low preference of vegetables. Therefore, families and schools should make efforts that juveniles can recognize the importance of vegetable intake and select various vegetables properly through the development of cooking methods and systematic nutrition education.

Physicochemical and sensory characteristics of turnip pickle prepared with different pickling spices were investigated. Turnip root slices(4${\times}$1${\times}$0.5 cm) were salted with NaCl and CaCl$_2$, and then soaked into pickling solution added to commercial (pickle P) or manufactured (pickle M) pickling spice, and then stored at 2$0^{\circ}C$. Throughout the whole storage periods, the acidity, pH, saltiness and reducing sugar content of two pickles were 3.1∼3.5%, 1.4∼1.7, 0.2∼0.6% and 25.2∼30.4 mg/mL, respectively. There were no significant differences between two pickles in saltiness, anthocyanin, reducing sugar content, color(Hunter L, a and b value) and hardness. However, acidity of pickle M was higher than that of pickle P throughout the storage time. Sensory results showed that the best edible time was the 14th day of storage, and at that time, scores of pickle M was higher in 리avor(7.3 and 6.9), taste(7.8 and 5.4) and over-all preference(8.0 and 6.1) than those of pickle P, and pickle M maintained good sensory qualities until 28th day of storage, compared to pickle P(p<0.05).

Yogurt base was prepared from whole and skin milk added with $0.5{\sim}2.0%\;(w/v)$ of cultured ginseng ethanol extract and fermented with lactic acid bacteria (Streptococcos thermophilus : Lactobacillus bulgaricus=1:1) at $37^{\circ}C$ for $24{\sim}30\;h$. Quality characteristics of the yogurt were evaluated in terms of acid production, number of viable cells, viscosity, and sensory property during lactic acid fermentation. Total contents of amino acids and some organic acids were analyzed. Addition of cultured ginseng extract stimulated the growth of lactic acid bacteria, and enhanced acid production and viscosity of yogurt. Total contents of amino acids of 0.5% cultured ginseng-added yogurt were higher than control group before fermentation, whereas glutamic acid, cysteine, valine, and phenyalaine contents increased after 30 h incubation. Contents of lactic, citric, and formic acids of 0.5% cultured ginseng-added yogurt increased during fermentation for 24 h. whereas decreased thereafter. Sensory scores of yogurts added with 0.5 and 1 % cultured ginseng extract were significantly higher than other groups in taste and overall acceptability. When cultured ginseng yogurt was kept at $5^{\circ}C$ for 15 days, its quality-keeping property was relatively good.

Brewer's yeast extract can be used as a good substrate for the culture of Lentinula edodes Mycelia(LEM). We found that it was better to filter the extract through three kinds of sieves and then to heat for hydrolysis and concentration at $90^{\circ}C$ prior to use. Also the maximum condition for the growth of LEM was investigated. We found that addition of inorganic salts such as calcium enhanced the growth of LEM. On the other hand, addition of carbon and nitrogen sources to the medium did not affect, and even inhibited under certain conditions, the growth of LEM. The maximum temperature for the growth of LEM was around $25^{\circ}C$. Also, it grows better when agitated by shaking at 100 rpm for airration. The appropriate concentration of the extract to use was 10%. Under these conditions, LEM could reach to the confluency after cultivation of 12 days. Our extract formula seems better than other available media for LEM growth, producing higher crude protein content and better taste.

The purpose of this study was to describe the way of life (such as smoking habits, alcohol consumption, exercise, duration of sleep, eating habits etc.), physical. psychological and overall health complaints and to identify the relationship between the way of life and health complaints of the nursing students. Data was collected with the self-administered OMI( Okayama Medical Index Health Questionnaire, devised Cornell Medical Index) from 766 nursing students and was analyzed. For data analysis, descriptive statistics and an ANOVA with an SPSS/PC+ program were used. The results were as follows: 1. The mean age of subjects was 21.0557(2.7618) years old in their 1st, 2nd, 3rd and 4th year-classes of nursing departments and college students in 4 regions of Korea. 62.1% of subjects were of the proper body weight, 2.0% were overweight, and 28.3% were underweight. Most subjects did not have a past history of disease, but 1.8% of subjects had experienced a blood transfusion. 2. 28.3% of the subjects had averaged 7 hours of sleep, 98.5% were nonsmokers, 91.2% were nondrinkers, 74.7% of subjects had milk intake sometimes, 53.7% of the subjects had an average salt intake, 49.6% of the subjects usually had a green vegetable intake, 45.4% of the subjects sometimes had fatty food intake, 64.8% of the subjects had good taste, 29.5% of the subjects enjoyed physical exercise. 3. The highest percentages of 'yes' among physical. psychological and overall health complaints were observed in the question 'Do you have gastric pain?'(60.2%), 'Are you confused of disorderly?' (37.2%), 'Physical body was burdensome and fatigued.'(57.3%). 4. The total O.M.I. score ranged from 1 to 89 with an average of 22.91(SD=12.10). A statistically significant difference was observed for the physical. psychological complaints for alcohol consumption. and for the psychological complaints for salt and fatty food intake. These conclusions should provide grounds for future studies of strategies for health promoting lifestyle for nursing students and their health concerns. Further research is required to investigate the life environmental and psychological factors affecting the way of life for nursing students and their health status, to analyze the health behavior of nursing students related with their culture and consciousness. Also epidemiologic research methodology, such as prospective cohort study should be considered to explore the performing process of nursing student's health behavior related with the occurrence of diseases.

Yogurt base was prepared from whole milk and skim milk added with 0.2∼1.0% (w/v) of Saururus chinensis(Lour.) Bail water extract (SCe) and fermented with lactic acid bacterias (the mixed strain of Streptococcas themophilus and Lactobacillus bulgaricus) at 37$\^{C}$ for 24 hr. Quality characteristics of the yogurt were evaluated in terms of acid production, number of viable cells, viscosity and sensory property during lactic acid fermentation. The composition of organic acids was also measured by HPLC. Addition of SCe stimulated the growth of lactic acid bacteria and remarkably enhanced the acid production. The viscosity and lactic acid content of yogurt were also increased by addition of SCe. The sensory score of yogurt added with 0.4% of SCe was significantly higher than other groups in taste and overall acceptability The storage abilities of yogurts added with SCe were relatively good at 5$\^{C}$ for 15 days.

For the effective use of the conger eel by-products, such as head and frame, Tang, which is the Korean-type soup, from conger eel by-products (TCEB) was developed and its food component characterization was compared with that of commercial Chueotang, loach Tang. According to the results of viable cells and coliform group of TCEB heated at $115^{\circ}C$ for various times, the reasonable $F_0$ value was 8 min. The proximate composition of TCEB was 90.7% for the moisture, 4.8% for the protein, 2.6% for the lipid, and 1.5% for the ash. The extractive-nitrogen content of TCEB was 243.1 mg/100 g, which was higher than that of commercial Chueotang, 208.0 mg/100 g. The total amino acid content of TCEB was 4,310 mg/100 g and its major amino acids were glutamic acid (637.3 mg/100 g, 14.8%), glycine (409.1 mg/100 g, 9.5%) and alanine (404.4 mg/100 g, 9.3%). TCEB was not felt in the sensual fish odor and its sensual taste was good. The health functional properties for health of TCEB were 1.29 as a PF (protection factor) for antioxidative activity and 39.4% for angiotensin Ⅰ converting enzyme (ACE) inhibiting activity.
