Using superoxide dismutase (SOD)-deficient mutants of Saccharomyces cerevisiae, the oxygen toxicity induced by paraquat was studied. In aerobic culture condition, yeasts lacking MnSOD (milochondrial SOD) showed more significant growth retardation than CuZnSOD (cytoplasmic SOD)-deficient yeasts. However, not so big differences in growth pattern of those mutants compared with wild type were observed under anaerobic condition. When exposed to paraquat, the growth of yeasts lacking CuZnSOD was severely affected by higher than 0.01mM of paraquat in culture medium. By the analysis of several cellular components ivolved in free radical generating and scavenging system, it was found that, under aerobic condition, the content of lipid peroxides in cell membrane as well as cellular activity of glutathion peroxidase of CuZnSOD-deficient mutants was increased in the presence of paraquat, although significant decrease of catalase activity was observed in those stratns. In MnSOD-deficient yeast, however, increment in cellular activity of glutathion peroxldase and catalase by paraquat was observed without any deterioration of membrane lipid. It implies that the lack of mitochondrial SOD could be compensated by both of glutathion peroxldase and catalase, but that only glutathion peroxidase might act for CuZnSOD in cytoplasm. In contrast, all of SOD-deficient mutants showed a significant decrease in catalase activity, but slight increase in the activities of glutathion peroxidase, when cultivated anaerobically in the medium containing paraquat. Nevertheless, any significant changes of lipid peroxides in cell membranes were not observed during anaerobic cultivation of SOD-deficient mutants. It suggests that a little amount of free radicals generated by paraquat under anaerobic condition could be sufficiently overcome by glutathion peroxidase but not by catalase.

The purpose of the present study is to analyze thematically everyday lives (food, clothing, shelter, spending, and leisure) of single women in their thirties or forties. As a result of the analysis, everyday lives of single women could be grouped into five main categories of themes which may be labeled as 'Self', 'Relationship', 'Survival', 'Preparation for the future', 'Freedom and hidden side of the freedom'. As for the first category of themes 'Self', three sub-themes have been found including "Only for me", "Perfection of self", "My own style". Next, as for the second category 'Relationship', two sub-themes have been found including "With her family (For her family, still under the protection of her family)", "With other people (Pleasures with people, Comfortable with single friends, Communicating with the world)". As for the third category 'Survival', three sub-themes have been found including "Health", "Safety", "Practice of living alone", As for the fourth category 'Preparation for the future', three sub-themes have been found including, 'Good spending', 'Savings for later life', 'Leisure in later life'. And finally, as for the fifth category 'Freedom and hidden side of the freedom', two sub-themes have been identified including "I am free because I'm alone (Freedom from bondage of my family, Compensation for being alone)", "Hidden side of the freedom (Fear, dislike feeling and insecurities due to being alone, Overcoming loneliness or solitude)". In all, there are eighteen sub-themes to consider. On the basis of these results, we presented some conclusions on the Everyday Lives of Single Women in their thirties or forties. We also presented some implications of these results on population education and future research.

The purpose of this study was to provide fundamental information for success factors of techniques through kinematic analysis including coordination of lower extremities and landing stability according to the success and failure of $540^{\circ}$ Dwihuryeochagi in Taekwondo. Twenty Taekwondo athletes: ten success group (S, age: $22.3{\pm}1.8$ yrs, height: $172.1{\pm}5.4$ cm, body mass: $64.4{\pm}4.2$ kg) and ten failure group (F, age: $22.3{\pm}1.8$ yrs, height: $172.1{\pm}5.4$ cm, body mass: $64.4{\pm}4.2$ kg) participated in this study. Three-dimensional motion analysis using a system of 3 video cameras with a sampling of 60 fields/s was performed during the competition of $540^{\circ}$ Dwihuryeochagi. Motions were divided into five events: pivot foot landing (E1), pivot foot toe off (E2), COM max height (E3), kick impact (E4) and landing (E5). At E1, the stride width was greater for S than for F (p<.05) while the time was greater for S than for F during P4 (p<.05). At E4, knee angle was greater for S than for F (p<.05). At E5, hip angle was greater for S than for F (p<.05) while kick distance was greater for S than for F (p<.05). Furthermore, at P3, the time would be related to kicking velocity (p<.05), while at P4, the time, range of hip angle and knee angle would be related to kick distance (p<.05). At P1, COM horizontal velocity would be related to COM vertical velocity of P1 and P2 (p<.05). Based on the findings, success factors of $540^{\circ}\acute{y}$ Dwihuryeochagi were COM horizontal velocity of P1, COM vertical velocity of P2, the time, kick distance, velocity, angle of lower extremities and coordination of P3-P4.

In order to ascertain the attitudes of residents to their health and the National Health Promotion Law, surveyors interviewed 1,220 subjects, 1% of men and women in Kyungsan city, who were twenty-year-old or more. The major findings are as follows: Men and women were 48.2% and 51.8%, respectively. The recognition rate of enacting and enforcing this law is 59.2% of men and 51.3% of women. With regard to the behavioral attitude to the health in the distinction of sex and age, current smokers are 31.2% of the interviewees, 61.6% of the men and 3.3% of the women. Current drinkers are 35.1%, 59.5% of the men and 12.3% of the women, but on the other hand there is little significance in the distinction of age. The acknowledgement proportion of enacting and enforcing this law is 59.2% of male and 51.3% of female. In terms of the recognition rate of the contents according to the general characteristics of interviewees, it appears that the indication of a warning expression on a packing paper of cigarette case and a liquor bottle is 92.4% and also the designation of a smoking free area in public facilities is 94.8%. Prohibition of cigarette-sale to the teenagers who are under 19, is 96.0%. Considering these facts, the recognition rate is high. On the contrary, 48.8% is accounted for encouraging a medical check-up before marriage which is in a low position. As a result of multiple behavior as a independent educational level, marital significant variables. In case of having undergone a periodic medical examination the recognition rate was high whereas frequent exercise led to the low recognition rate. Concerning the details of the undertaking in accordance with each factor of general characteristics, the greater part of them have been appraised successfully whether it is recognized or not. On the other side, no effect got answered about the result of the undertaking subjects to general and peculiar behavior attitude towards health was in effect or not. A great majority approved of more reinforcement of legal regulation about smoking and drinking regardless of whether they perceived the details of the law of promotion of National Health Promotion Law or not. Additionally there was significant difference in reinforcing legal regulation of smoking and drinking in compliance with the attitude of the substance of this law. With regard to education, public relations and evaluation about national health through public health centers by our government, the younger and the higher in education they are, the more deficient they feel. First of all, those who were aware of the enforcement of this law as well as plenty of scarcity answered that better service of disease prevention had to be expanded than ever. In consideration of the above-stated results, the education to public health and the business of public relations should be reinforced and a practical campaign for health life should also spread out for the purpose of encouraging to practise healthy life-style.

Quality characteristics of mash of takju prepared by wheat flour nuruks (conventional and improved style) were investigated during fermentation. Those were cultured with wild microorganism on whole and crushed wheat (wheat nuruk), wheat flour and mixture of rice and wheat flour, and nuruk cultured with Aspergillus oryzae on wheat flour. Ethanol content reached maximum of 10.6-17.4% after 14 days of fermentation. And the ethanol contents of takju were high in order of wheat nuruk, wheat flour nuruk, Aspergillus oryzae nuruk and mixture of wheat flour and rice nuruk. No difference of pH was among the treatments while the wheat flour nuruk cultured with wild microorganisms contained higher amounts of acids than the others. The amount of total sugars ranged from 16.22-17.74% on the starting day of fermentation, and decreased to 4.28-6.10% after 14 days. The amount of total sugars in mashes brewed with wheat flour nuruk cultured with Aspergillus oryzae was measured to be highest at the beginning stage of fermentation. Afterwards no difference was found among the types of nuruks. Glucose was in the range of 2,735-7,842 mg% at initial period of fermentation, afterwards it was rapidly decreased. The total amounts of free sugar for control and the wheat flour nuruk was higher than other treatments. The total amounts of organic acids were the highest in wheat nuruk to 690-2,241 mg% and the contents of lactic acid and succinic acid were high in mixed rice nuruk to 183-1,293 mg%. The contents of lactic acid and succinic acid were higher than those of the other kinds of organic acids in takju.

This investigation grasps the level and relevant elements of performance of health promotional activities for the elderly in Korea. It provides fundamental data on health promoting projects targeting the elderly population from farming villages. Hence, this study gropes for an effective approach and measures of health promoting programs. The program needs to be developed with a focus on elderly people from farming villages. In addition, it was carried out in order to provide basic data for development of health projects for local communities. Data gathering was based on survey data targeting patients from the free clinic service. Service was rendered for the residents of farming villages, and conducted at the Offices of CheonBuk Province from October 2000 to December 2000. Analytical results were used to examine the health promotional method for the elderly in the aspect of Oriental Medicine. SPSS 9.0 version as well as T-test and ANOVA were used for survey data analysis. Piersons correlation coefficient was utilized for the relationship for each area, obtaining the following analytical results. 1. The average score for the activities of health promotion was 2.28. Looking at each subcategory, stress management was the highest at 3.65; interpersonal relationship, 3.00; nutrition, 2.55; health responsibility, 2.15; self-realization, 2.03; and exercise was the lowest at 1.89. 2. With respect to lifestyle of the health promotion secondary to general features of elderly people from farming villages, the level of activities of health promoting lifestyle was shown to be higher for males than that of females. Self-realization area was high among males in detailed particulars while the level of execution was high as age decreases in the stress area. 3. Regarding health promoting life style secondary to socioeconomic characteristics, the level of execution was higher for the individuals with a higher level of education and further utilization of spare time. With respect to occupation, the level was highest for people from the fishery. The level decreased in the order of other occupations such as trade, unemployed and agriculture, which was shown to be the lowest. In detailed particulars, it revealed that higher the individuals educational level, the higher the self-realization and stress management areas. The level of interpersonal relationship was the highest among people with little or no education. With respect to self-realization area, the level was highest among the cases where one paid living expenses along with their children. The lowest level of living expenses was seen in the cases where an individual pays for living expenses by himself/herself. There were significant results in all areas except for nutrition areas depending on occupation. The fishery was shown to be the highest. The level of activities was higher as one utilizes more spare time in all areas except for the area of interpersonal relationship.

The consumption of KimChi, which Korean are a favorite food, has dramatically increased by changes of life style and waste as by-products in KimChi factory. This study was conducted to evaluate an effect of compost of caster oil cake (COC) mixed with waste from KimChi factory (KWF) and its growth effect of lettuce. Treatments were consisted of 4 treatments as COC compost (60% COC+40% sawdust) as control, control+35% KWF (K-1), control+50% KWF (K-2), and control+65% KWF (K-3). Temperature, pH, O.M. and microbial phase of COC composts blended various ratios of KWF or free were unaffected. It was appeared that nitrogen content of KWF treatments was higher, but the ratio of organic matter and nitrogen was lower than the control. Although KWF treatments were acceptable compost under the guideline of Korean, NaCl content of K-3 was 1.91%, and it was very higher than that of others. In comparison with fresh weight and dry weight of lettuce, K-1 and K-3 were similar to control. These results indicated that the waste from KimChi factory was possible to use the composting raw blended materials below 35% mixtures.

Korean foods sold restrant and hotel accompaines so many kinds of side dishes. The menues never considered on the nutritional standpoint nor the volume that can be eaten by customers. The purpose of this study is to simplify and improve the menu of Korean foods sold in restrant. To find out the problem and the method of the betterment Korean food sold in restrant. The survey study was made for 100 restrants in Seoul city. Ther average number of side dish of the restrant food was 23. The average amount number of the side dish was 31 and smallest number was 4. The average amount of food served was 979 grams and the average number of food taken by people was 698 grams. The average percentage of intake of food was 62%. Protein Content of the foods sold restrant was from 54% to 240% over the recommended dietary allowances. Protein intake also exceeded from 19% to 147% of recommended dietary allowances. Age of the customers were surveyed to set up the standard amount of the nutrients. About 68% of the customers were from 30 to 40 years of age in the day time (lunch), whereas about 72% were from 20 to 30 years of age in the evening (supper). From the results of the survey study, two nutritional standard were decided to be used. One is the recommended dietary allowences of 25 years of man (reference man), and the other is that of 45 years of man. The actual standards are as follows : Standard 1 (25 years of man) Calories-900~1000Cal Protein-25-30g Vegetables-200~250g (include yellow, green vegetable), Amount of food-about 800g Standard 2 (45 years of man) Calories-700~800Cal Protein-25~30g Vegetables-150~200g (include yellow, green vegetable) Amount of food-700g The kinds of food recommended to be sold in the restrant are as follows : 1. Pansang-is a formal method of korean table setting 3 types, 7 chup, 5 chup, and 3 chup were studied and made, 2. Table for the quest with drink-2 types of table setting, 9 kinds of food and 7 kinds of foods were studied. 3. free meal-in this table, one pig protein dish with kimchi, one vegetable, and one salty flsh will be served, 19 kinds of foods were studies. 4. One dish meal-in one large dish, rice will be served with side dishes soup and kimch will be accompanied, 10 kinds of foods were studied. 5. Cafeteria style foods-one serving of food will be served in small dishes Customers should select the food want to eat.

This experiment was carried out to investigate the fertilization and the size of mature female and male gametophytic parts of Pulsatilla koreana after artificial pollination. The size of pollen is $26.5{\mu}m$ at the time of anther dehiscence, that is, about $3{\sim}4$ days after pollination. Synergid nucleus, egg nucleus, and polar nucleus are 10.0, 15.0, and $32.5{\mu}m$ respectively at the time of completing egg apparatus formation, that is, about 2 days after pollination. Poller tubes germinate on stigma about 10 hours, passing lower part of style about 30 hours, penetrating into micropyle about 35 hours after pollination. Sperm nucleus penetrates into polar nucleus about 40 hours and egg cell about 48 hours after pollination. But, there seems to be different among the individuals. Multinuclei and multinucleoli are formed in egg cell, synergid, and polar nucleus about the time of fertilization. Proembryo is formed about 4 days, being changed to large globular form about $6{\sim}8$ days after pollination. Endosperm nuclei divide into free nuclei after fertilization and change to cotyledon in gymnosperm. There seems to be same phenomena in Pulsatilla koreana.

The current study was conducted to examine the effect of feeding and management practices on milk quality and dairy farm productivity in Korea. Fifty dairy farms in Gyunggi (11), Gangwon (22), Chungnam (17) provinces were surveyed to collect data on the herd size, housing style, feeding management, waste disposal, milking practices and milk yield. Milk tank samples from all farms under study were also collected to enumerate its composition and quality parameters. Large dairy herds are equiped with better housing, milking and waste control facilities than medium and small dairy herds. Higher concentrate feeding to lactating cows was noticed in small dairy herds (47.51 %) than in medium (32.59 %) and large dairy herds (31.82 %). The decrease in concentrate feeding to lactating cows with increase in number of cows per farm resulted in a simultaneous increase in the use of imported forages. Bacterial count in milk was affected by housing and milking facilities at dairy farms. Higher bacterial counts (Coliform and E. coli) in milk were observed in cows housed in stanchion than those under free stall with saw dust bedding. The bacterial counts were higher with bucket milking system than with pipe-line and parlour systems. The increase in the number of dairy cows per farm and thus better management and milking facilities resulted in a reduction in somatic cell score. Milk yield (per cow) was higher in herds with less somatic cell score. Average milk protein concentration was between 2.89 to 2.98 % and milk urea nitrogen was between 21.81 to 23.31mg/ml on surveyed dairy farms. This study concluded that large herd size with better dairy cow management facilities is crucial to produce quality milk with better dairy farm income.
