Fermented foods have been recognized as functional foods that provide health benefits, including the modulation of intestinal microbiota. Therefore, the aim of the present study was to examine the effects of coffee beans fermented with Lactobacillus plantarum and Bacillus amyloliquefaciens on healthy human gut microbiota. Fermentation increased the content of beneficial substances (i.e., flavonoids and polyphenols). The consumption of fermented coffee increased the occurrence of beneficial microorganisms such as fiber degraders and short-chain fatty acid producers, although no significant microbiota shifts were observed after the coffee consumption. The analysis of metabolic activities also showed no difference after the coffee consumption. Our study demonstrates that the consumption of the fermented coffee may increase some beneficial bacterial while remaining the gut microbiota and its activities.

Health of a nation is quite often represented by the statistics such as infant death rate and maternal mortality rate. It is indisputable that maternal child health(MCH) is the basis of health of a nation. MCH is also one of the cardinal component of primary health care. The importance of MCH is conspicuous especially in the developing countries. In Korea, People in the rural communities still have high access barrier to basic health care needs, including MCH services. Access to quality care during pregnancy and delivery seems to be the crucial factor in preventing deaths in women and children. The beneficial effects of prenatal and postnatal care on the outcome of pregnancy for mother and child, and those of health professional-attended institutional delivery on the health of mother and child have been well documented in many studies. Recognizing these effects, the government of Korea received IBRD loan of $30 million in 1979 for th purpose of constructing 89 rural MCH centers. The construction is complete now and all 89 MCH centers are under operation ti imporve primary health care for mothers and children in Korea. However, it has been observed over time that overall performance of public MCH centers is declining. The decline has been attributed partly to low quality services by public MCH centers, poor management by health center mangers, competition with for-profit private clinics, and to the development of national health insurance. This study investigates the utilization by rural communities in Korea of MCH services provided by public sector health centers deemed to be physically and financially accessible to the community but suboptimally used. It seeks also to determine the factors that influence people's utilizations. This study sets out to discover a desirable form of MCH center from among alternative forms of centers, thereby to construct a MCH model.

One of the most powerful health management practices is the use of antibiotics, but their use is being restricted because of health safety issues. The swine industry has been looking for various alternatives to antibiotics and increasingly considers the use of dietary factors like feed ingredients, feed additives, feed formulation practices, or feeding methods, instead of using antibiotics to improve pig health and performance. Among other alternatives to antibiotics, spray-dried plasma may be a candidate. Spray-dried plasma is a blood product that provides bioavailable nutrients and physiologically active components such as immunoglobulins, glycoproteins, growth factors, peptides, etc. It is an excellent protein source with balanced and highly digestible amino acids. Several beneficial physiological activities depend on components of spray-dried plasma, such as immune competence (antibacterial activity), modulation of microbiota and/or immune system, integrity of intestinal barrier function, etc. These beneficial effects can contribute to improvement of pig performance and health by modulation of microbiota in the digestive tract and/or immune system. Therefore, it is suggested that spray-dried plasma has great potential as an antibiotics alternative.

Purpose. Tai Chi exercise, an ancient Chinese martial art, has drawn more and more attention for its health benefits. The purpose of the study was to identify the effects of a Sun-style Tai Chi exercise on arthritic symptoms (joint pain and stiffness), motivation for performing health behaviors, and the performance of health behaviors among older women with osteoarthritis. Methods. Total of 72 women with the mean age of 63 years old were recruited from outpatients clinic or public health centers according to the inclusion criteria and assigned randomly to either the Tai Chi exercise group or the control. A Sun-style Tai Chi exercise has been provided three times a week for the first two weeks, and then once a week for another 10 weeks. In 12 weeks of study period, 22 subjects in the Tai Chi exercise group and 21 subjects in the control group completed the posttest measure with the dropout rate of 41 %. Outcome variables included arthritic symptoms measured by K-WOMAC, motivation for health behavior, and health behaviors. Results. At the completion of the 12 week Tai Chi exercise, the Tai Chi group perceived significantly less joint pain (t = -2.19, P = 0.03) and stiffness (t = -2.24, P = 0.03), perceived more health benefits (t = 2.67, P = 0.01), and performed better health behaviors (t = 2.35, P = 0.02), specifically for diet behavior (t = 2.06, P = 0.04) and stress management (t = 2.97, P = 0.005). Conclusion. A Sun-style Tai Chi exercise was found as beneficial for women with osteoarthritis to reduce their perceived arthritic symptoms, improve their perception of health benefits to perform better health behaviors.

Protamine has been widely used as a pharmaceutical product and natural food preservative. However, few studies have been conducted to assess the beneficial function of dietary protamine. This study examined the effects of dietary salmon protamine on serum and liver lipid levels and the expression levels of genes encoding proteins involved in lipid homeostasis in the liver of rats. Groups of male Wistar rats were fed AIN93G diet containing 2% or 5% protamine. After 4 weeks of feeding these diets, markedly decreased serum and liver cholesterol (CHOL) and triacylglycerol levels were noted. Increased activity of liver carnitine palmitoyltransferase-2 and acyl-CoA oxidase, which are key enzymes of fatty acid ${\beta}$-oxidation in the mitochondria and peroxisomes, was found in rats fed on protamine. Furthermore, rats fed protamine showed enhanced fecal excretion of CHOL and bile acid and increased liver mRNA expression levels of ATP-binding cassette (ABC) G5 and ABCG8, which form heterodimers and play a major role in the secretion of CHOL into bile. The decrease in triacylglycerol levels in protamine-fed rats was due to the enhancement of liver ${\beta}$-oxidation. Furthermore, rats fed protamine exhibited decreased CHOL levels through the suppression of CHOL and bile acid absorption and the enhancement of CHOL secretion into bile. These results suggest that dietary protamine has beneficial effects that may aid in the prevention of lifestyle-related diseases such as hyperlipidemia and atherosclerosis.

Purpose: The aim of this study is to examine the effects of egg consumption and suggest proper guidelines for consumption of eggs by determining the relationship between eggs and cholesterol. Methods: Literature review was conducted on the relationship between nutritional, functional properties of eggs and serum cholesterol, as well as cardiovascular disease. Results: Eggs, which are a good protein food with complete amino acid composition, contain vitamin A, riboflavin, vitamin $B1_2$, folic acid, vitamin D, vitamin E, vitamin K, calcium, iron, choline, selenium, ${\beta}$-carotene, lutein, zeaxanthin, etc. However the egg yolk has a high cholesterol content, which is associated with chronic diseases, including heart disease and hypertension. As a result, its intake is subject to regulation. Outbreak of heart disease by yolk intake can show different results depending on the characteristics of the subjects, amount of egg intake, and the implications of other foods eaten. It is difficult to determine whether eggs are beneficial, as they are the main supplying source for other major nutritive elements as well. Several research studies insist that when cholesterol intake increases by 100 mg, the level of serum cholesterol increases by 2.2~4.5 mg/dL and when serum cholesterol increases by 1%, the risk of heart disease increases by 2%. This indicates that a large intake of eggs can increase the risk of heart disease. Although the cholesterol of egg yolk and serum cholesterol are correlated, it is insufficient to conclude that only cholesterol and not other components are related to heart disease. In fact, other components in egg such as various unsaturated fatty acids and phospholipids could be related as well. Rather than concluding egg as a 'good' or 'bad' food according to its cholesterol content, it is important to define egg as a part of dietary patterns. Conclusion: Generalizing an indiscriminate and uniform amount of egg intake for all seems inadequate. However, patients with diabetes or heart disease should pay particular attention to the amount of egg intake. As for the norm, eating egg with vegetables as a substitute for other animal products seems beneficial.

Palm kernel expeller (PKE), a by-product of palm oil extraction, contains higher amounts of fiber than corn and soybean meal, but offers low energy density, protein value, and amino acid (AA) composition, limiting its use for swine. Recently however, it was reported that dietary fiber has a positive effect on the gut microbiota of the host, and therefore it is necessary to study the effect of PKE feeding on the intestinal microbiota of swine. In this study, we investigated the effects of supplementation with PKE in lactation diets on the gut microbiota composition of lactating sows and their litters. A total of 12 sows were randomly assigned to two dietary treatment groups in a completely randomized design. The treatments were a diet based on corn-soybean meal (CON) and CON supplemented with 20% of PKE. Sow and piglet fecal samples were collected before farrowing, on days 7 and 28 (weaning) after farrowing, and on days 7 and 28 (weaning) after farrowing, respectively, to verify gut microbiota composition by pyrosequencing analysis. The beta-diversity result showed a significant difference only in weaning-stage piglets, but dietary PKE altered the gut microbiota in sows by increasing the abundance of Lactobacillus compared with CON. In piglets, dietary PKE decreased the abundance of opportunistic pathogen Proteus and increased the abundance of potentially beneficial bacteria, such as Prevotellaceae and Prevotella. Our results can be helpful in developing feeding strategies and support the beneficial effects of dietary PKE to improve the gut health of animals.

The study aims to examine whether regular leisure activity of the elderly with active and passive types has a beneficial effect to enhance their health condition. The elderly subjects of 164 (82 of elderly who do active leisure and 82 of elderly who do passive leisure) aged over 60 years in Suwon area were employed. Survey questionnaires were administered to investigate general characteristics, life style, and health status along with anthropometric measurement. From the findings, the elderly who do active leisure were highly educated and better in living status. The elderly who do passive leisure showed higher drinking and smoking rates as well as higher obesity and overweight rates in comparison to the other counterpart. Furthermore, the elderly who do passive leisure were poor in health status. 'Painful knee and eye', 'lower back pain', and 'fatigue' were the most prevalent among subjective symptoms of the elderly. In conclusion, the elderly with active leisure activity seemed to have better life style and maintain good health status. Therefore, it is critically important to establish the health program combined with various leisure activity for the seniors to promote and energize the later years of life.
