The purpose of this study was to investigate the dietary intakes of preschool children in rural areas and to develop programs of nutrition education, offering the mothers an appropriate advice for the improvement of the dietary practices corresponding to the modernization of the agriculture. The daily food intakes of 118 preschool children, randomly selected from the farm household, were studied by means of three-day records during summer season of 1972. The results showed that the dietary intakes of food groups such as meats and fishes, beans and the products, milks and small fishes, fruits, fats and oils were below 50 per cent of the recommended level-especially in that of milk. Therefore, the diet was generally below the recommended dietary allowances for protein with good quality, fat, calcium, vitamin A, thiamine, reboflavin and ascorbic acid. The dietary data revealed that most of preschool children in rural areas consumed rice and barley, almost every day. Other foods eaten less frequently were soybean paste, gimchi, potatoes, flour, and summer squash. The use of cereals should be curtailed some what and the use of milks, fishes, poultry, meats and protein extenders should be increased.

The stressful physiological and environmental conditions around weaning often promote the proliferation of pathogens in the digestive tract of piglets resulting in diarrhoea and reduced daily weight gain. Typical dietary practices to maintain growth performance and health have led to an increased use of antimicrobial growth promoters. Due to the advanced ban of antibiotics in pig production, new concepts have been developed to secure animal health and growth performance, feed efficiency, and product quality as well. Several naturally occurring compounds seem to beneficially affect the composition and activity of the microflora in the gastrointestinal tract (GIT) of pigs. These are, among others, organic acids, probiotics, prebiotics, and enzymes. Organic acids are already widely used, especially in pigs, due to their positive effects on GIT health and growth performance. Probiotics have been shown to be effective against diarrhoea though effects may be dependent on diet composition and environmental conditions. Prebiotics may influence composition and activity of the intestinal microflora. Additionally, pre- and probiotics may exert positive influences on immune response, whereas enzymes may enhance feed digestibility by breaking down anti-nutritional factors. In the following, the focus will be directed to the role of organic acids, probiotics, prebiotics, and feeding enzymes as potential modulators of GIT health.

This study was described as midwife's role and obstacle of midwife's role expansion. Midwife as primary medical personal who practices for a mother and infant health care and promotion of mother infant interaction. As the trend of increasing natural childbirth, midwifery has to provide childbearing care those who want delivery in a midwifery center. This study conducted to survey for 44 midwives who work at the midwifery center. The results of the study as fellows. 1. Most of the midwives role was care of pregnancy, delivery, postpartum women and babies. Another role was conducted educational classes childbirth, breast feeding, contraception and sexual education. 2. Some midwives role perform breech, vaccum delivery, episiotomy and suture, pitocin induction and augmentation, ultrasonogram, giving medication, anesthesia, collecting specimen from Pap smear and vaginal discharge. Midwife perform these roles without medical law support. 3. Most of the obstacles of the midwife role was the medical law limitation. Midwives want revise medical law to perform simple treatment for childbearing women and babies. 4. Half of the midwives refer cases to medical doctor in case of complication of women and newborns. 5. Current frequency of home birth rate is slightly higher than before and me cases like to have delivery under water. Finally, midwife and midwifery have to prepare to meet childbearing woman, baby and family's need. For activation and expansion of midwife's role, every midwife has to be aware of medical law accurately and they must know what practice they can do and what practice they can not do.

Due to increased number of women workers in Indonesia in the last decade, numbers of women living as a worker and a housewife have increased. This also increases the potential risk of breastfeeding discontinuation. Three months of maternal leave policy and inadequate lactation promotion support in workplace have been identified as factors that hinder lactating practices. The World Health Organization recommendation of 6 months of exclusive breastfeeding and joined regulation of three Indonesia ministers (Ministry of Health, Ministry of Labour, and Ministry of Women Empower) have failed to improve the exclusive breastfeeding rate among female workers in Indonesia due to the lack of a standardized guideline on lactation promotion at workplace. In addition, very limited or no studies have been conducted to evaluate the impact of workplace-based lactation intervention programs on exclusive breastfeeding rate among female workers. This is because the relationship of lactation with working performance and productivity could not motivate employer to invest in workplace-based lactation promotion facility or program.

The passenger pigeon (Ectopistes migratorius) was a species of pigeon that was once the most common bird in North America. According to some ornithologists, the number of passenger pigeons is estimated as many as five to six billions at the time when the first Europeans arrived there. But this species became extinct in 1914. There were a multiplicity of causes in the extinction; first, the extension of telegraph lines and railroads into the Middle West of the USA beginning in 1850s, second, the loss of vast feeding, nesting, and roosting sites of the passenger pigeon due to the massive deforestation, third, the rapid population growth of the USA during nineteen century, fourth, the commercial exploitation of the species, and finally, the infirm and weak protective efforts. Some important lessons can be learned from the extinction of the passenger pigeon. First, it shows how much critical the public interest is for a successful conservational movement. Second, it illustrates the need for strong laws and practices in the protection of an endangered species from going extinct. Third, the fate of the passenger pigeon proves a very important principle in conservational biology. That is, for each species (bird or other animal) there is a minimum population to sustain the species. Ecologists generally believe that the extinction of the passenger pigeon was due to the loss of their numbers below the minimum owing to overexploitation.

Purpose: To compare normal weight children with obese children in terms of family factors, eating habits, and sociocognitive factors. Method: This study compared 217 obese children with 231 normal standard weight children of 4th-6th graders from 7 elementary schools in Kangwon province. The study also surveyed 817 their parents using questionnaires in which familial factors, eating habits, and sociocognitive factors such as dietary self-efficacy, locus of control and self-esteem were included. Result: Obese children had more obese family members, more family members with chronic metabolic disease, and lower breast-feeding rate than normal weight group. Dietary self-efficacy was positively correlated with eating habits and locus of control while no correlation was found with obesity index.. Self-esteem was negatively correlate with obesity index. Both the parents and the childrens eating habits showed significant positive correlation to the obesity index. Conclusion: These results implied familial factors, eating habits, and sociocognitive factors influenced childhood obesity. Thus, further research targeting to positive attitude toward familial dietary practices combined with significant sociocognitive factors, may lead to prevention and effective management of childhood obesity.

In Korea, several national cross-sectional surveys monitor the diet, nutritional status, and health status of children. This continual dedicated national surveillance system contributes to the identification of nutritional and health issues, establishment of public health policies, and development of nutrition recommendations. This paper provides recent information about the Korea National Health and Nutrition Examination Survey and the Korean Youth Risk Behavior Web-based Survey and describes key nationwide survey findings published in the last 5 years on infant feeding practices and the dietary intake and nutritional status of Korean infants, children, and adolescents. There have been increasing trends in children, and teenagers who skip breakfast, eat fast food, consume sugary drinks, have vitamin D deficiency, and are obese. This review will inform pediatricians, nutritionists, and other health care practitioners who track children's growth and development. It may also help researchers and policymakers identify diet-related policies and strategies for chronic disease prevention in Korean infants, children, and adolescents.

Hemipteran bugs, which were previously considered as secondary pests, have currently become important pests of numerous crops. Among them, Riptortus pedestris (Fabricius) is a major species that occurs in Korea, Japan, China, and South Asian countries. Riptortus pedestris infests leguminous crops like soybean, vetches, and red clover; fruit trees like persimmon and yuju; and grains like barley, foxtail millet, broomcorn, and sorghum. Riptortus pedestris causes the greatest damage to soybean, as it is the most suitable host for the bug. Feeding damage during pod formation significantly reduces the yield of soybean. Currently, 17 insecticides, including diazinon and etofenprox, are registered for the control of hemipteran bugs in Korea, and growers apply insecticides two to three times on a regular basis. Aggregation pheromone traps are widely used as a monitoring tool and partial control measure. The aggregation pheromone of R. pedestris attracts conspecific adults and nymphs and is used for food exploitation rather than sexual attraction. In addition, the pheromone serves as a kairomone for egg parasitoids such as Gryon japonicum (Ashmead) and Ooencyrtus nezarae Ishii. As a new method of pest management, nonviable host eggs were included in the pheromone trap to catch R. pedestris and propagate parasitoids. As a part of cultural practices, resistant soybean varieties with specific color and size of pod and control of flowering time through the alteration of planting date can be used. For the effective management of R. pedestris in the near future, development of cultural practices that can support natural control factors and the use of multiple control tactics are needed.

Milk urea nitrogen (MUN) determination is being used an indicator of the protein-energy balance in dairy herds. A faulty balance can be corrected to optimize milk production and animal health. This parameter is regarded as a potential tool to evaluate suboptimal feeding practices and reproductive disorders. Therefore, the purpose of this study was to investigate the response of milk composition by regular feeding analysis and to compared the relationship between MUN and milk protein(MP) and fertility at the insemination period in Holstein dairy cows. Total of 355 artificial insemination (AI) for 150 Holstein cows in the herd were used to examine the relationship between MUN and MP content and conception rate. The AI occured for the cows 50 to 150 day in milk, and MUN and MP concentration were determined using automated infrared procedures. The mean${\pm}$standard deviation of MUN and MP concentration in the herd were $15.6{\pm}2.1mg/dl$ and $3.23{\pm}0.38%$, respectively. MUN contents of bulk milk were increase by elevated crude protein intake. The conception rate was lower in the cows in which the level of MUN was lower than > 8.0mg/dl (10.0%) or > higher than 25mg/dl (15.4%) relative to the cows in MUN content of 12.0~17.9 mg/dl (36.7%) at the time of insemination. Also, lower MP than 3.0% or higher MP than 3.25% were associated with a lower conception rates. Consequently, MUN and MP analyses may be used serve as a monitoring tool of protein and energy nutritional balance to improve reproduction efficiency in Holstein dairy cows.

The use of antibiotics in Korean swine production has been changing to a restricted use of in-feed antibiotics. These antibiotics, which are also growth promoters, are powerful for disease control. Due to this issue, the swine industry is consistently looking for any kind of alternatives to antibiotics such as new feed ingredients, feed additives, feed formulation practices, or feeding methods to improve pig health and performance. In general, dietary factors provide bioavailable nutrients and/or affect physiological activity to modify the physiological condition, immune system, or microbial population of pigs to improve their performance and health. Thus, it is suggested that dietary factors may be important components in the growth and health management of pigs. Using an alternative grain feed such as rice, barley, and oats, low protein diets or low-high energy diets can be used as solutions to manage the effect of stress factors that cause growth and health problems at specific time points during the stages of pig production. Several studies support that these alternative feeds and dietary factors may improve pig growth and health by changes in intestinal conditions, immunity, or other physiological conditions compared with typical feed ingredients and diet management in pig production. Therefore, feed ingredients, low protein levels, and different energy contents in swine diets were reviewed to better understand how these dietary factors can contribute to improved pig performance and health under different physiological conditions.
