Infanthood is a crucial period when mental and emotional developments take place along with physical growth. Adequate supply of nutrition is essential during this period and there is an urgent need for proper education and guidance on balanced nutrition. Therefore, this study was designed to assess to current status of lactation and to investigate mothers' perspectives on human milk and formular milk. As random samples for this study, a total of 352 mothers having infant under the age of 4 were surveyed. 27.3% of mother surveyed were breast-feeding, 38.0% were formula-feeding and 34.7% were mixed-feeding. According to the result of this study, the percentage of breast feeding was on the decrease, while the dependence on formular milk was on the rise. The main reason of formula-feeding was insufficient secretion of human milk on mothers part. The major factors that affect to select feeding method were employment status, degree of education, family income and age. Also, the interviewees desired the product fortified with special ingredients that are hot contained in formular milk currently available in the market. The most concerned problem of formula milk was indigestion and the interviewees wanted the formular milk to be improved digestibility.

The purpose of this study was to assess the hygiene status of 145 child-care foodservices, which were newly registered in the Center for the Children's Foodservice Management (CCFSM) in Changwon, Gyeongnam. Sanitary inspection checklist (40 food safety items) of Korea Food and Drug Administration (KFDA) was used by the CCFSM in Changwon, Gyeongnam. Average score from the total safety items in 145 child-care foodservices was 21.41 points out of 40 points. Score gaps between the lower group (71 foodservices, 13.92 points) and higher group (74 foodservices, 28.61 points) showed a significant difference (P<0.001). The top five priorities of sanitary measures needing corrective actions for child-care foodservices were as follows: 'provide hand washing and sanitizing tools, and supply manuals on how to wash hands properly', 'supply record form for access/inspection', 'conduct education for cooks on standards in the selection of sanitizer for raw vegetables and proper methods to wash and sanitize raw vegetables', 'provide a refrigerator and a freezer with installed thermometers and temperature record monitoring logs', 'encourage separation of contamination operating zone and clean zone or conduct training for cooks on ways to prevent cross-contamination by performing work separately by the hour'. For the higher group, most were national/public facilities (83.3%), whereas in the lower group, private facilities (62.1%) were more common than national/public ones (37.9%). Therefore, a significant difference (P<0.001) was detected in the two groups. These private facilities should be supported.

Early growth, the rate of yolk sac absorption, and nucleus size in liver parenchymal cells were correlated with the nutritional status of first feeding larval haddock, Melanogrammus aeglefinus. Larvae that successfully began exogenous feeding maintained high growth rates, delayed yolk sac resorption, and had larger hepatocyte nuclear sizes than starved larvae. At 10 days post hatch (DPH) the cumulative mortality in the starved larval haddock group was 100%. The area of the hepatocyte nuclei in starved larvae gradually decreased, reaching its lowest value by 9 DPH. Our results support the current practice of providing the first food supply at 3 DPH. Hepatocyte nuclear size can be used to assess larval haddock nutrition status, and may be a good criterion for assessing the success of transition from endogenous to exogenous feeding.

Finding alternative and renewable energy sources has become an important goal for plant scientists, especially with the demand for energy increasing worldwide and the supply of fossil fuel being depleted. The most important biofuel to date is bioethanol which is produced from sugars (sucrose and starch) found in corn and sugarcane. Second generation bioethanol is targeting studies that would allow the use of the cell wall (lignocellulose) as a source of carbon by non-food plants. Plant scientists, including breeders, agronomists, physiologists and molecular biologists, are working towards the development of new and improved energy crops especially, how to design crops for bioenergy production and increased biomass generation for biofuel purposes. This review focuses on: i) the current status of first generation bioenergy production, ii) the limitations of first and second generation bioenergy, and iii) ongoing research to overcome challenging issues in second generation bioenergy.

Korea's agriculture had many inherent problems. Korea is a mountainous country with only 22 percent farmland and less rainfall than most other neighboring rice-growing countries. A major land reform in the late 1940s and early 1950s spread ownership of land to the rural peasantry. Individual holdings, however, were too small or too spread out to provide families with much chance to produce a significant quantity of food. The enormous growth of urban areas led to a rapid decrease of available farmland, while at the same time population increases and bigger incomes meant that the demand for food greatly outstripped supply. The result of these developments was that by the late 1980s roughly half of Korea's needs, mainly wheat and animal feed corn, was imported. Korea's agriculture is facing a new round of difficulties from the inevitable process of market opening. Therefore, we have reviewed the agricultural status and soils in Korea how we can meet the coming issues with respect to production and prospect based on the government documents and articles published on the journals.

The survey was carried out to obtain some fundmental data to improve the dietary life and to establish the nutritonal education and policy on inhabitants limed in isle area near by demilitarized zone in Korea. For this, 33 families in the area of Kyodong island located at Kanghwa-Gun, Kyungki province were randomly selected. Trained surveyors visited each house to survey the food and nutritional status in summer during 3 days in August, 1987. The results are summarized as follows ; The number of foods they were taking totalled 17 categories and 134 kinds of which 104 kinds were vegetable foods. The average amount of food intake was 1465.3g per person per day, animal food occupied 9.6% only. The intake amount of fruit among vegetable foods, and fishes, shells, milk and eggs among animal foods was lower than the national average. Each proportion of carbohydrates fat and protein to the total energy intake was 70.4%, 9.7% and 19.9%. The foods they used to take a lot were rice, potatoes. cucumbers, cabbage KIMCHIE and YULMOO KIMCHIE in order of their intake amount. The energy intake was 3064 Kcal which is higher than nutritional requirements, and the energy ratio of cereals to the total energy in take is 76%. If the amount of fat intake is fixed to 20% of total energy intake, the amount of fat intake is 68g, but the actual amount of fat intake was only 33g. With an increase of total energy intake, supply of calcium and vitamin A should be increased much more.

Objectives: This study was performed to investigate the effect of active nutrition care on feeding and nutritional status of elderly patients receiving long-term enteral tube feeding. Methods: Subjects included 77 elderly patients who had received enteral nutrition more than one week before admission. Nutrition care was provided to patients supplied less calories than required. Feeding intolerance was examined and managed every day and formula was adjusted to meet nutritional requirement during the first 3 months after admission. Patients were classified into under or over 80% of percent ideal body weight (PIBW) and medical records were used to compare changes in weight,, biochemical indices, and nutritional status during the study. Results: Weight, BMI, triglyceride and total cholesterol in blood, hemoglobin, and hematocrit levels were significantly lower in patients under 80% of the PIBW than in those over 80% of the PIBW at admission. The percentage of supply to required calories was also lower in patients under 80% of the PIBW. After 1 month of nutritional care, supplied volume of formula was significantly increased in patients under 80% of the PIBW. Weight, BMI, and PIBW were increased and there were no differences between groups after 6 months. In addition, the concentrations of triglyceride and total cholesterol in blood, hemoglobin, and hematocrit tended to increase in patients under 80% of the PIBW, leading to no difference between groups after 3 months. Conclusions: Personalized active nutrition care is effective to increase weight and improve feeding and nutritional status in underweight elderly patients receiving long-term enteral nutrition.

The use of local product foods and fresh-cut products, the dietitian's recognition, the required items and the quality for school foodservice was investigated to increase the consumption of high-quality agricultural products. Data from 578 elementary schools, 228 middle schools and 116 high schools were collected by school foodservice personnels in each regional Education Administration in Gyeong-gi province. The first criteria of buying food materials was reliability/safety for all school foodservice. The second criteria were the origin of the product and freshness/ripeness for elementary and middle schools and high school, respectively. The most important consideration for selecting a supplier was the quality of the material. The appearance/status of the food was the first factor for buying food materials. The origin and the seasonality were very important for buying farm products. Dietitians in Gyeong-gi province recognized the local products, and used them weekly. The advantages of using local products were the quick supply, freshness and safety. On the other hand, the disadvantages were the lack of information and the uncertainty of supply. Sixty eight percent of the subjects had experienced the high-quality agricultural products in school meals, but the frequency was low. The main reasons for not servicing high-quality agricultural products were the high cost and the lack of trust on the quality. Among fresh-cut products, seasonings and root vegetables were purchased most frequently, but leaf vegetables was 5.7% only. The purchase of fresh-cut products was not frequent, but usually satisfied. The advantages of fresh-cut products were the reduced workload and waste, but the reason for not using them were poor hygiene and the high price. The diverse supply system and the promotion of the local product foods would be necessary since the most food materials were purchased through suppliers. In addition, the problems related to the high cost and distrust should be resolved to expand the consumption of the high-quality agricultural products and the fresh-cut vegetables. The institutions for certifying the quality should be needed to increase the confidence of these products.

Infanthood is a crucial period when mental and emotional developments take place along with physical growth. Adequate supply of nutrition is essential during this period and there is an urgent need for proper education and guidance on balanced nutrition. Therefore, this study tried to set the direction for developing baby food by investigating the conditions of weaning status and mothers perspectives on weaning. According to the result of this study, the average period when interviewees began weaning of their infants is 4.1 months and finishing period of weaning is 14.2 months on average. The frequency of consuming commercial weaning food is once a week. As high as 88.4% and the fruit juice was mainly used as the starting weaning food. The consumtion rate, more than once a day, is as high as 60%, they use commercial weaning food for convenience, especially when they are out. The 65% of surveyed group show rather dissatisfactory view about the commercial weaning food, and wanted improvements and changes. Interviewees wanted to obtain the information on baby food sold in the market and how to prepare baby food through technical literatures, and they frequently relied on commercial baby food due to its convenience. The most desired type of baby food was semi-solid paste in a disposable package that can be stored at room temperature.
