This study conducted to investigate incidence rate and association of serum lipid profiles with incidence of ischemic heart disease. Study subjects consisted of 417,642 adults aged 30 years and over, who underwent physical examination and responded to questionnaire from health examination center of 19 university general hospitals. Hazard ratio of risk factor for ischemic heart disease (IHD) were calculated by Cox's proportional hazard regression model adjusted for ages, BMI and lifestyle (drinking, smoking and exercising). For TC/HDL ratio, hazard ratio of IHD in male increased from 1.21 times to 1.84 times increase with TC/HDL ratio, and that in female also increased from 1.26 times to 1.86 times. For TG/HDL ratio, hazard ratio of IHD in male increased from 1.17 times to 1.49 times increase with TG/HDL ratio, and that in female also increased from 1.42 times to 1.97 times. For LDL/HDL ratio, hazard ratio of IHD in male increased from 1.26 times to 1.82 times increase with LDL/HDL ratio, and that in female also increased from 1.26 times to 1.68 times. In conclusion serum lipid indexes are the significant risk factors for cardiovascular diseases. The higher the concentration of TC, LDL and TG is, the lower the concentration of HDL is, hazard ratio for IHD increased. Ratio of TC/HDL, TG/HDL and LDL/HDL were also verified to be significant risk factors for IHD.

The purpose of this study was to obtain the serum lipid levels according to the lifestyles, and examine the influence of lifestyles on the serum lipid levels among adults who examined the health checkup in an university hospital. The subjects for this study were 4,112 adults who underwent medical examinations at the health center of a university hospital in Daejeon city from Jan 2012 to Dec 2013. The lifestyles and serum lipid levels of study subjects were obtained from self-recorded questionnaires and medical examination charts of the hospital. As a result, the mean values of the serum lipid levels (TC, HDL-C. LDL-C and TG) and atherogenic index (AI) of the study subjects showed a significantly difference according to the lifestyle, such as age, alcohol consumption, smoking, regular exercise, overeating and meat consumption in both sexes. The TC, HDL-C. LDL-C, TG and AI showed a positive correlation with age, AUDIT score, but the HPI score showed a negative correlation in both sexes. In the age-adjusted odds ratio, the risk ratio of an abnormality of TC, HDL-C. LDL-C, TG and AI increased significantly because there was an increase in the group of everyday overeating and meat consumption, smoking group, no exercise group, and low HPI group than their respective counterparts in both sexes. The above results suggested that the serum lipid levels of the subjects was closely related to increasing age, and lifestyles, such as alcohol consumption, smoking, regular exercise, overeating, and meat consumption.

BACKGROUND/OBJECTIVES: Chewing difficulty is a factor contributing to a poor nutritional status in the elderly. The aim of this study was to examine disparities in food and nutrition intakes among Korean elderly people with and without chewing difficulty. SUBJECTS/METHODS: This study utilized data from the sixth Korea National Health and Nutrition Examination Survey conducted in 2013. The study subjects included males and females over 65 years of age who were not required to adhere to a special diet due to disease or sickness. They were divided into groups according to their chewing ability. Those who found chewing "very difficult" or "difficult", were combined to form the chewing difficulty group. Similarly, those who found chewing "moderately difficult", "easy", and "very easy" were combined to form the normal chewing group. RESULTS: Of the 999 subjects, 47.7% had chewing difficulties and the prevalence of chewing difficulty was higher in females than in males (P = 0.03) and higher in those 75 years of age and over than in younger individuals (P < 0.001). The chewing difficulty group had a significantly lower intake of fruits and vegetables (P < 0.05) and lower vitamin C and potassium intake than those in the normal group. Comparison of the percentages of Dietary Reference Intakes for Koreans (KDRIs) in the two groups indicated that the intake of most nutrients (energy, vitamin C, thiamin, riboflavin, niacin, calcium, phosphorus, sodium, potassium, and iron) were significantly lower in the chewing difficulty group than in the normal group. In particular, calcium intake was inadequate (51% of KDRIs) in the chewing difficulty group. CONCLUSIONS: The results indicate that chewing difficulty is closely related to food and nutrient intake in the elderly and can result in vitamin and mineral intake deficiencies. It is evident that the care of elderly subjects with chewing difficulty is essential for maintaining a healthy lifestyle.

Disease of patient who visited the hospital can cause different symptoms of the disease, depending on the environment and lifestyle. Recent medical services offered in patients has changed in the environment that can be selected for treatment by analyzing the patient according to the disease symptoms. In this paper, we propose an efficient method to manage disease control because the treatment method may change at any patients suffering from the disease according to the patient conditions by grouping the different treatments to patients for disease information. The proposed scheme has a feature that can be ingested by the patient big disease information, as well as to improve the treatment efficiency of the medical treatment the increase patient satisfaction. The proposed sheme can handle big data by clustering of disease information for patients suffering from diseases such as patient consent small groups. In addition, the proposed scheme has the advantage that can be conveniently accessed via a particular keyword, the treatment method according to patient disease information. The experimental results, the proposed method has been improved by 23% in terms of efficiency compared to conventional techniques, disease management time is gained 11.3% improved results. Medical service user satisfaction seen from the survey is to obtain a high 31.5% results.

The aim of this study was to evaluate the effect of kale (Brassica oleracea acephala) juice supplementation on serum lipid levels and phospholipid (PL) fatty acid compositions in hypercholesterolemic men. Thirty-two men with hypercholesterolemia (>200 mg/dl) were recruited among the faculty and staff at Y University after annual health examinations. The subjects consumed 150 ml of kale juice per day for a 12-week intervention period. Dietary and anthropometric assessments were performed before and after supplementation, respectively, to ensure that the subjects maintained their usual diet and lifestyle throughout the intervention. Serum concentrations of HDL-cholesterol and the ratio of HDL-cholesterol to LDL-cholesterol were significantly increased (p<0.001) after intervention. Serum LDL-cholesterol concentration and atherogenic index were significantly reduced (p<0.001). Levels of 12:0, 14:0, $18:1{\omega}9$, $18:3{\omega}6$, and sum of monounsaturated fatty acids (MUFA) in serum pholspholipid (PL) were significantly increased, while $22:4{\omega}6$ level was significantly reduced (p<0.05). It can be speculated that kale juice, containing large amounts of antioxidant nutrients, contributes to changes of serum-PL-fatty acid compositions and the improvements of serum lipid profiles. This study demonstrates the supplementation of regular meals with kale juice may favorably affect serum lipid profiles and serum-PL fatty acid compositions and, hence, could lower the risks of coronary artery disease in men with hypercholesterolemia.

The purpose of this study was to examine the effects of a cheonggukjang diet and aerobic exercise on lipid metabolism and antioxidant enzyme activity in rats. Thirty-two Sprague Dawley rats were randomized into a cheonggukjang diet with aerobic exercise (A), aerobic exercise (B), cheonggukjang diet (C), and control group (D). The cheonggukjang diet group consumed 20 g of 20% cheonggukjang a day with their normal diet. Exercise training consisted of treadmill running (25~40 min, 5 day/wk) and the exercise intensity was gradually increased. The results are as follows: T-C was significantly lower (p<0.05) in A compared to B and C. TG was significantly lower (p<0.001) in A compared to D. B and C were significantly lower than D. HDL-C was significantly higher (p<0.05) in C compared to D. LDL-C was not statistically different across the groups. Additionally, TBARS were not statistically different in the control or experimental groups. SOD was significantly lower (p<0.05) in A compared to D. C was significantly lower (p<0.05) that of D. CAT and GPx failed to reach the statistical difference between experimental and control groups. The major findings of this study were that aerobic exercise with a chenggukjang diet intervention improved lipid profiles and antioxidant capacity in this animal model. Therefore, a cheonggukjang diet and aerobic exercise will help to improve antioxidant capacity and prevent lifestyle related diseases.

Fermented milks have been recognized as healthy foods since ancient times, but those using intestinal bacteria such as Bifidobacterium and lactic acid bacteria (LAB) are even more valuable from the standpoint of view of maintaining health. They have also now come to be recognized as important in the field of preventive medicine. Although advances in the medical sciences in the last 50 years have significantly increased the human lift span, an unfortunate fact is that many of us are now living long enough to experience chronic disorders such as coronary heart disease, hypertension, osteoporosis, diabetes and cancer. In recent years there has been renewed interest in health promotion and disease prevention by incorporating probiotic bacteria into foods to counteract harmful bacteria in the intestinal tract. Therefore, there are now a wide variety of commercial products containing prospective probiotics that claim health-promoting effects, such reductions in large botvel carcinogens and mutagens, antitumor properties, cholesterol-lowering effects, increased lactose digestion, relief from con-stipation, stimulation of immunocomponent cells and enhancement of phagocytosis. Two well-known representative probiotic is LAB and Bifidobaclerium. Traditional probiotic dairy strains of LAB which have been designated as GRAS (Generally Recognized As Safe) bacteria have a long history of safe use and most strains are considered comestible microorganisms with no pathogenic potential. Accordingly, there is considerable interest in extending the range of foods containing probiotic organisms from dairy foods to infant formulas, baby foods, and pharmaceuticals. In addition, the ingestion of probiotics, prebiotics, and symbiotic as wll as combinations of pro- and prebiotics has recently aroused renewed interest as enhancing the beneficial relationship between the host and intestinal microflora in both healthy and diseased indivisuals. Non-communicable chronic diseases such as cancer, cerebral hemorrhage, is chemic heart disease, and diabetes mellitus has recently been recognized as adult diseases in Japan as well as other countries. and are considered to be inevitably associated with aging. These diseases occur as a result of individual life styles. The Japanes Government. Ministry of Health, Labor and Welfare has proposed substituting the term 'adult diseases' with 'lifestyle-related diseases'. It has emphasized the importance of prevention rather than treatment. since the well-known increase in the elderly population in Japan is predicted to result in a variety of socioeconomic problems. n this lecture on the Present status of fermented milk products in Japan, I will report a strategy for the development of fermented milk products in Japan from the standpoint of view of research in Japan on LAB and Bifidobacteria. They could play an important role in preserving human health by controlling intestinal microflora capable of producing toxic effects on the host.

The demand for small-sized housing has been increasing due to the recession of real-estate price and the increase of small-sized households. Especially, the demand for affordable housing has been increasing since the style of housing and the location fits the lifestyle of small-sized household. In addition, many investors have been buying it because it has advertised as an investment property holding high-return ratio. However, an empirical analysis about the selling price and the return ratio has not been done yet. Therefore, the purpose of the research is having the empirical analysis based on the selling price and return ration by examining the affordable housing in Seoul. The urban-life housing more than 50 generations of the Seoul was irradiated for the analysis. And the linear regression analysis and PLS(Partial Least Square Regression) analysis was used for the empirical analysis. The result of analysis, based on the linear regression analysis, showed that factors including neighboring housing price and subway catchment area have a significant effect to the determinant factors of housing price. The analysis for return ratio showed neighboring housing price, subway catchment area and amenities affects the ratio. Especially, the fault of using small sample was covered by using the partial least square regression in this research.
