As a basic study to elucidate nutritional physiology and composition of synthetic medium of red rotting bacteria, Erwinia carotovora, of ginseng, the effects of hydrogen ion concentration, various kinds of carbon sources, nitrogen source, micrometallic salts and it's concentration on the gorwth of the bacteria were investigated and the results were as follows. Optimal pH in the basal medium for the growth of the bacteria was 6.5. After incubation the pH in culture media was neutralized. Among the various kinds of carbon sources, sucrose, glucose mannitol, but organic acids were not utilized effectively as nutrients. After incubation the pH turned acidic. Alanine as organic nitrogen sources nad ammonium sulfate as inorganic nitrogen promoted the growth, but L-valine and sodium nitrite were the least effective. Ferric chloride 1.0mg/dl and ferrous sulfate 100mg/dl were the most effective as micrometallic sources. Control and boric acid were the least effective. New synthetic medium based on the above results was follows ; Alanine 1.0g, $KH_2PO_4\;1.0g, \;sucrose\;30.0g, \;MgSo_4{\cdot}7H_2O\;0.5g, \;FeCl_3{\cdot}6H_2O\;1.0mg\;thiamine\;200{\gamma}g$, and distilled water 1000ml, pH6.5.

This study was conducted to evaluate the necessity and development of a therapeutic diet manual which contains basic nutritional science concepts that refer to nutritional management of patients in clinical settings. One hundred and fifty-four medical doctors, forty dietitians, and sixty-three students majoring in nutrition participated. The survey included questions about nutritional knowledge, nutrition-related concerns, and nutrition counseling in medical practice. The knowledge score of medical doctors was 47.7%. Lower percentages occurred in the amount of sodium allowed in the sodium restricted diet and the food sources of vitamin B1 were 16.9%, 31.2% respectively. Seventy-four percent of doctors strongly urged nutrition counseling for patients. Seventy one percent of doctors agreed that the present medical-nutrition education was inadequate in medical school curricura. Most doctors (79.2%) agreed that a therapeutic diet manual would be helpful and necessary. The average percentage of nutritional knowledge test scores for dietitians and students majoring in nutrition were 76.0% and 68.3%, respectively. Over ninety percent of dietitians working and their prescriptions. The result of this study strongly suggests that the development of a comprehensive therapeutic diet manual is necessary, especially for medical doctors.

This study was conducted to investigate the relationship of calcium intake , serum calcium level to calcium supplementation and the effect of nutritional education in middle-aged women. The age distribution of the subjects was 49-55 years. Daily nutrient intakes and dietary sources of calcium were analyzed by convenient method and food frequency questionnaire. At the same time, fasting blood samples were collected and serum calcium and magnesium concentrations were measured before and after nutritional education. The BMD of subjects were measured by Dual Energy X-ray Absorptiometry(DEXA). Serum calcium and magnesium concentrations were significantly(p<0.05) different between pre and post nutritional education. After nutritional education, nutrient intakes were significantly increased(p<0.05), especially calcium. This results suggested that dietary calcium intake as well as nutritional education seem to be important in preventing in middle-aged women.

The dietary intake of nutritional elements by Koreans as determined by the Ministry of Health and Welfare's National Nutrition Survey have been reported for $1969{\sim}1993$. But these data were based on not dish but food. Therefore, the purpose of this study was to compare dish sources of energy and macronutrients (carbohydrate, fat, protein) in the diets of three area (large city, small city and rural). Dish sources were evaluated from two-day record obtained in the secondary analysis of the 1993 Korean National Nutrition Survey. The result, large city and small city had higher fat and protein intake than did rural. Otherwise, carbohydrate intake among rural was higher than those among large and small city (p<0.05). The primary dish source of energy and macronutrients was cooked rice for all area. The percentage of cooked rice in daily carbohydrate intake was 52.64% for nationwide, 48.40% for large city, 50.52% for small city, 61.79% for rural. The cumulative percent of top 10 dish sources to carbohydrate for large city, small city, rural were 78.02%, 81.16%, 85.69%, respectively. These was higher than cumulative percent of other macronutrients. The milk as good protein source ranked 3 for large city, 6 for small city, 22 for rural. The major dish sources to fat were cooked rice and pork that prepared by various cooking way. These results show that the major dish sources of energy and macronutrients were cooked rice based of Korea traditional consumption pattern. The most of nutrient intake consumed some dishes for all area. The dish consumption pattern was generally similar between large and small city. But rural was different from other area. Threfore, nutrition educations and interventions should be targeted to each area and should be attended with studies that comparision of dish sources to nutritional elements by specific age-sex groups.

Consumers purchase bakery products and evaluate them with various wants and needs when they need them. It shows that there are changes and improvements in quality factors like nutritional consideration rather than simply eating for survival. The purpose of this study was to research how well the consumers perceive necessary nutritional information, how nutritional information on bakery products affects the consumers' perceived risk and evaluation, and how consumers' perceived risk on bakery products affects their evaluation on them. The research was done through surveys for the people in the Busan Metropolitan area. 200 out of 250 answers were used in analyzing frequency, factor, and simple regression through SPSS Win 10. The findings were as follows; first, the more nutritional information consumers have, the less perceived risk they feel, i.e., positive nutritional information affects reducing the consumers' perceived risk. Second, as perceived risk gets reduced, consumers' evaluation on bakery products has meaningful influence on their perceived risk level. Third, these consumers' perceived risk affects their evaluation on bakery products meaningfully. The results of this study can be the meaningful base of information sources in establishing marketing strategies in bakery industry.

This study was conducted to investigate the effects of feeding different carbohydrate sources and garcinia cambogia extract(HCA) on body weight and lipid metabolism. Fifty 10-month-old male Sprague-Dawley rats weighting $635{\pm}6g$ were randomly divided into 5 groups and fed different experimental diets for 4 weeks. The carbohydrate(CHO) sources of each group were cornstarch(control group, 100% of CHO), fructose(F group and FH group, 25% of CHO) and sucrose(S group and SH group, 25% of CHO). FH group and SH group were fed diets containing 1%(W/W) of HCA. Food intake, body weight gain, and calorie efficiency were not significantly different among the groups. Perirenal fat pad weight of FH group was significantly lower than F group, but epididymal fat pad weight was not different among the groups. Fasting glucose level were not significant among the groups. Plasma lipid profile of FH or SH group was slightly lower than F or S group, respectively. The degree of difference of plasma lipid level was greater between F and FH group than those of between S and SH group. In liver, total lipid, triglyceride and total cholesterol level were slightly higher in F group than S group, and tended to be lower in FH group than F group, but tended to be higher in SH group than S group. Liver citrate lyase activity were not significant among the groups. These results suggest that HCA is potential material for reduction of body weight and improvement of plasma lipid profiles. But, there was no difference between fructose intake with HCA and sucrose intake with HCA in reduction of body weight and lipid metabolism.

Zinc is ubiquitous in all living cells. Structural and catalytic properties of cellular enzymes are zinc dependent. Zinc deficiency leads to a variety of pathological abnormalities with immune impairment. It is an established fact that nutritional status contributes to overall immune response of individuals. Outcome of zinc deficiency on immune system is so drastic that it is difficult to conceive at the first instance. Zinc supplementation has been advocated to prevent diarrheal disease in children with poor nutritional status. The bioavailability of zinc depends upon its sources. Moreover it varies between monogastrics and ruminants. Controversy still prevails between inorganic and organic sources of zinc with respect to their superiority in bioavailability. Zinc exerts immunostimulatory effects in various laboratory and farm animals. Animals having congenital zinc deficiency diseases like A46 lethal trait usually die due to impairment of the immune system unless treated with zinc. The immune mechanism of zinc and its effect on animals and man are discussed. Zinc has been considered as extremely safe at higher therapeutic doses, but does not provide any beneficial effect but rather may cause immunosuppression. More recently, zinc has been prescribed for immunodeficient hosts, to modulate the immune system so that to a certain extent it can combat against opportunistic pathogens.

A 6-week feeding trial was conducted to determine the nutritional value of various dietary animal protein sources in juvenile Koran rockfish. White fish meal (WFM), flounder muscle meal (FMM), blood meal (BM), casein & gelain (CG), egg white albumin (EWA) and squid liver powder (SLP) were used as the animal protein sources, Crude protein content and available energy of the experimental diets were 50% and 15.9 kJ/g, respectively. There were significant differences among all dietary groups in weight gain (WG), feed efficiency (FE), and protein effiency ratio (PER). WFM and FFM were the best animal protein sources among the dietary groups. FMM diet had significantly higher (P<0.05) WG, FE, and PER values than those of fish fed the WFM diet. WG, FE, PER, and specific growth rate (SGR) values of fish fed BM diet were significantly higher (P<0.05) than those of fish fed EWA diet. Significant differences were found in whole body composition, hemoglobin (Hb), hepatosomatic index (HSI), and hematocrit (Ht). These results showed that low-temperature processing of lyophilized flounder muscle meal resulted in superior performance of rockfish relative to the other evaluated animal protein sources.

The questionnaires answered by 832 college students were analyzed for nutrition knowledge, food habits, and the sources of nutrition information. The students had a high level of perceived knowledge(88%), that is the knowledge that each subject believed he had, but the accuracy of the knowledge was only 55%. The mean score of nutrition knowledge was 7.20 out of possible 15.0 points and the mean food habit score was only 3.90 out of possible 10.0 points. And 59% of the subjects belonged 'poor food habit' group. The female subjects showed higher scores than male students in the perceived knowledge, the accuracy of the knowledge, the mean nutrition knowledge score, and the food habit score. There was a high correlation between nutrition knowledge score and food habit score of the subjects. The male students ranked mass media, high school courses, and parents as their primary sources of nutritional information, while 78% of female subjects ranked high school courses as their first choice of nutritional information.
