Recently the attention of the trace elements in arisen to the biochemical importances and the biochemical significances have been discussed and shown by several workers. And also UN-narcotic Committee has shown that geographical difference of Optimum based on the produced area, would be significant on its contents of trace elements. The problem of Rice in Korea is urgently important on the nutritional and agricultural view points for the soil improvement of its production and for the betterment of health program. In order to check the adaptability of cultural problems to the different qualities of the with regards to the kinds of rice spieces and in order to know the comsumption of trace elements through rice, the contents of trace elements on 40 samples of the polished rice sampled from the different areas consisting in 8 kinds of rice species are studied on contents of Al, MN, Ni, Zn, Co, Cu and Fe in this paper. Though the further wide spread studies should be carried out. It seems that Al, Fe and Ni contents show little differences by the kinds of rices species and Cu, Al, Mn, Zn, and Ni contents show geographically little differences. But these differences are not significant statistically. The Co was not detected from the rice samples. It is not clear whether Co content in rice is a undetectable amount or the Co is absent in rice at all.

Purpose: The purpose of the study was to identify the amount of calcium intake during late pregnancy and breastfeeding and compare the differences in the amount of calcium by subjects' characteristics. Methods: With a descriptive survey design, 121 Korean breastfeeding women were recruited in a community setting. The list of foods and drinks with calcium extracted from the study of Song and So (2007) was used to measure the amount of calcium intake during pregnancy and lactation. The subjects' characteristics were collected to identify differences in the amount of calcium intake. Results: Mean age of the women was 31 years old. Amount of calcium intake was 568mg per day during late pregnancy and 431mg per day during breastfeeding. These amounts were quite lower than a recommended dose that adult women should consume a daily minimum of 1,000mg of calcium. Women who had higher household income and attending experience for nutritional education took more calcium during breastfeeding and late pregnancy, respectively. Conclusion: More than a half of the breast-feeding women do not consume the recommended dose of calcium. Education for proper calcium consumption during pregnancy and lactation should be an additional subject in the prenatal and breastfeeding education program for women's bone health.

The egg's interior quality is one of the most important criteria for commercial producers and consumers. Internal quality is complex, including aesthetic factors such as taste, freshness, nutritional and processing values, and the genetic influences upon these upon these factors ranges from none to considerable. The rate of cholesterol synthesis in the hen is very high compared to other animals and humans. Genetic selection, diet drugs and other chemicals can alter cholesterol concentration in the plasma of laying hen, but attempts to manipulate the cholesterol concentration in the egg yolk are generally unsuccessful since the cholesterol can only be changed to a small extent. Factors which may affect the degree of pigmentation of the yolk include the type of xanthophyll and its concentration in the feed, the feed composition, and the health of the hen. Several feed ingredients interact with carotenoid pigment to improve or reduce their deposition rates in yolks. Egg weight is determined by genetics, body size prior to first egg housing density, environmental temperature, lighting program, total feed consumption, calcium, phosphorus, niacin, water, methionine, total sulfur amino acids, energy, linoleic acid, fat and protein levels. Eggs need to be promote levels. Eggs need to be promoted a versatile commodity and new processed egg items need to be developed. Organic eggs are laid by hens which were raised in chemical and drug frdd environments. There are still difficulties in producing these eggs due to the availability of organic poultry feeds and cost of organic grains.

Morning sickness during pregnancy is a very common functional problem with different kinds of symptom, but little data are available concerning the nutrition intervention program fur pregnant women in local area. A total of 152 pregnant women who had experienced morning sickness were surveyed to investigate the relationships between morning sickness, nutrient intakes and pregnancy outcome. The results showed that prevalent symptoms were nausea (68.4%), heartburn (59.2%), morning sickness (48.7%), vomiting (42.1%), and constipation (44.7%). The onset of the symptom occurred during the first 3 months (9.3 $\pm$ 2.3 weeks) ; 21.1% of the subjects was experienced two symptom at the same time. This significantly correlated with vomiting (p < 0.01), nausea (p < 0.001), morning sickness (p < 0.001), and heartburn (p < 0.01) with pregnancy weight. There were also correlations between the four symptoms and nutrient intakes. Mean birth weight of 21 newborns was 3.06 $\pm$ 0.42 kg, and the one and five minutes of Apgar scores were 7.74 $\pm$ 0.99 and 8.84 $\pm$ 0.69, respectively. There were negative correlations between vomiting and pregnancy outcomes (p < 0.05). Our data support that morning sickness, especially vomiting during pregnancy is associated with Apgar score and body weight of newborn. (Korean J Community Nutrition 8(2) : 138~148, 2003)

Recent development of novel techniques in systems biology have been used to improve and manipulate the rumen microbial ecosystem and gain a deeper understanding of its physiological and microbiological interactions and relationships. This provided a deeper insight and understanding of the relationship and interactions between the rumen microbiome and the host animal. New high-throughput techniques have revealed that the dominance of Proteobacteria in the neonatal gut might be derived from the maternal placenta through fetal swallowing of amniotic fluid in utero, which gradually decreases in the reticulum, omasum, and abomasum with increasing age after birth. Multi "omics" technologies have also enhanced rumen fermentation and production efficiency of dairy goats using dietary interventions through greater knowledge of the links between nutrition, metabolism, and the rumen microbiome and their effect in the environment. For example, supplementation of dietary lipid, such as linseed, affects rumen fermentation by favoring the accumulation of ${\alpha}$-linolenic acid biohydrogenation with a high correlation to the relative abundance of Fibrobacteriaceae. This provides greater resolution of the interlinkages among nutritional strategies, rumen microbes, and metabolism of the host animal that can set the foundation for new advancements in ruminant nutrition using multi 'omics' technologies.

Purpose: This study identified the effects of chronic disease number, quality of sleep and, serum serotonin concentration on the elderly's depression in order to provide basic data for the development of intervention program to effectively prevent and manage depression of the elderly living in the community. Methods: The study surveyed 207 people aged 65 or older living in the community. The general characteristics of the subjects, the number of chronic diseases, the quality of sleep (PSQI-K), the hematological test (Serotonin) and the depression (K-GDS) were statistically analyzed using SPSS/WIN 23.0. Results: It was shown that the elderly's depression differed significantly depending on the number of chronic diseases, the quality of sleep, and serum serotonin concentration, and that the variable that most affected depression was the quality of sleep. Next, the number of chronic diseases and serum serotonin levels were the variables affecting the depression of the elderly. Conclusion: In order to prevent and manage the depression of the elderly in the future, treatment and education for diseases and depression should be provided to the subjects. In particular, nursing interventions are needed to improve the quality of sleep for the elderly. Health care programs should also be provided, such as providing nutritional supplements to provide serotonin and increasing daytime activities.

Purpose: This study aimed to explore and understand the health promoting behaviors of low-income overweight and obese women in Korea. Methods: Data were collected from 10 low-income overweight and obese women working at a community self-sufficiency center through semi-structured in-depth interviews. Individual interviews were conducted and transcribed. Deductive content analysis was done, using the MAXQDA program. Results: The health promoting behaviors practiced by low-income overweight and obese women were affected by intrapersonal, interpersonal, and organizational/ community factors. Six categories were identified and two category clusters were derived that could best describe their health promoting experiences. As main category clusters, despite "feeling that the body and mind are not healthy" participants noted "difficulty maintaining a healthy lifestyle." Overall, the participants had poor nutritional status, lacked physical activity, experienced much stress in intrapersonal level, and faced intrapersonal-level barriers to health promoting behaviors. Moreover, participants had a lack of personal will, and lack of specific information to practice health promoting behaviors, a lack of time, and too many overall burdens to earn a living for their family while trying to maintain health promotion behaviors. Conclusion: Lifestyle interventions for nutrition management, encouragement of physical activity, and stress management are needed for overweight and obese low-income women. In addition, social support and policies are needed to improve their living environment.

The objectives of this study were to determine the recognition of food waste, school lunch leftovers and satisfaction toward school lunch in middle school students in Seoul. Four hundred students were surveyed beginning April, 2007. The results are summarized as follows. The primary means in which students learned about environmental pollution were 'video media' (54.7% males, 39.2% females) and 'by teachers' (23.2% males, 33.0% females). The primary effects on food habits after participating in the school lunch program were 'having a balanced diet' (23.3%) in the females, and 'decreased intake of junk food' (24.9%) in the males. The serving sizes for cooked rice, soup, and meat were higher in the females (3.46, 3.46, and 2,91, respectively) than the males (3.18, 3.29, and 2.73, respectively). The primary school lunch leftovers for one week were cooked rice (4.55), meat (4.35), kimchi (3.84), fish (3.60), vegetables (3.38), and soup (3.08). Importance-performance analysis of the school lunch meal indicated that good taste had high importance, but low performance. Nutritional balance, food safety, cleanliness of tableware and supplies, clean uniforms of employees, and cleanliness of the dining area had both high importance and performance.
