Purpose: This cross-sectional study aimed to document the dietary behaviors, dietary changes, and health status of female marriage immigrants residing in Gwangju, Korea. Methods: The survey included 92 female immigrants attending Korean language class at a multi-cultural family support center. General characteristics, health status, anthropometric data, dietary behaviors, and dietary changes were collected. Results: Mean age of subjects was 31.3 years, and home countries of subjects were Vietnam (50.0%), China (26.0%), Philippines (12.0%), and others (12.0%). Frequently reported chronic diseases were digestive diseases (13.2%), anemia (12.1%), and neuropsychiatry disorder (8.9%). Seventeen percent of the subjects was obese ($BMI{\geq}25kg/m^2$). Dietary score by Mini Dietary Assessment was 3.45 out of 5 points. Dietary scores for dairy foods, meat/fish/egg/bean intake, meal regularity, and food variety were low, and those for fried foods and high fat meat intake were also low. Thirty-three percent of subjects answered that they have changed their diet and increased their consumption of fruits and vegetables after immigration. Length of residence in Korea was positively associated with BMI and waist circumference. Length of residence tends to be positively associated with dietary changes and obesity as well as inversely associated with disease prevalence. Conclusion: The study shows that length of residence is inversely related to disease prevalence. However, this association is thought to be due to the relatively short period of residence in Korea and thus the transitional phase to adapting to dietary practices. As the length of residence increases, disease patterns related to obesity are subject to change. Healthy dietary behaviors and adaptation to dietary practices in Korea in female marriage immigrants will not only benefit individuals but also their families and social structure. Therefore, varied, long-term, and target-specific studies on female marriage immigrants are highly needed.

This study was designed to compare the lipid components between wild and cultured snakehead, Channa argus. The lipid components of cultured snakehead were analyzed and compared with that of wild snakehead. In both edible portion and viscera, the lipid content in cultured, snakehead was higher than that in wild one. In the fatty acid composition of neutral lipid in edible portion, percentages of $C_{14:0},\;C_{16:0},\;C_{18:1},\;C_{20:5},\;C_{22:5}\;and\;C_{22:6}$ in cultured snakehead were higher than those in wild one, while percentages of $C_{18:0},\;C_{16:1},\;C_{18:2},\;C_{18:3},\;C_{20:4}\;and\;C_{22:4}$ lower. In the case of phospholipid in edible portion, percentages of $C_{16:0},\;C_{18:1}\;and\;C_{22:6}$ in cultured snakehead were higher than those in wild one, while percentages of $C_{16:1},\;C_{18:2},\;C_{18:3},\;C_{20:4},\;C_{22:4}\;and\;C_{22:5}$ lower. The unsaturation (TUFA/TSFA) and w3 highly unsaturated fatty acid content (w3 HUFA) of neutral lipid in cultured snakehead were higher than those in wild one, while those of phospholipid lower. The essential fatty acid contents (TEFA) of both neutral and phospholipids in wild snakehead were higher than those in cultured one. In the ratio (A/B) of fatty- acid content (A) in cultured snakehead to that (B) in diet, the A/B ratios of $C_{18:2\;w6},\;C_{18:3\;w3},\;C_{20:5\;w3}\;and\;C_{22:6\;w3}$ were 0.3 to 2.5 times, and it is considered to be related to the biosynthesis of polyenoic acids and growth rate of cultured snakehead.

This study investigated the effects of silkworm droppings (SWD) added diet feeding on quality characteristics of pork loin meat Pigs were divided into 7 treatment groups (10 pigs/group) and subjected to one of seven treatment diets $(0,\;1\%,\;2\%\;and\; 3\%\;SWD\;for\;4 weeks,\;1\%\;2\%\;3\%$ SWD for 8 weeks, SWD diets; total fed diets) before slaughter. Pork loin were collected from the animals (110kg body weight) slaughtered at a commercial slaughterhouse. Pork loin meat were packaged aerobically and then stored at $4^{\circ}C$ for 2, 5, 8, or 12 days. Samples were analyzed for general composition, texture characteristics and physico-chemical properties. pH value was not significantly different between the control and SWD treatment groups. pH of control and SWD treatment groups were increased as the storage period passed General composition, cooking loss and texture was not significantly different between the control and SWD treatment groups. WHC of SWD treatment group was higher than that of control group. WHC of control and SWD treatment groups were significantly decreased as the storage period passed (p<0.05). Meat and fat color (CIE $L^{\ast}$, $a^{\ast}$, $b^{\ast}$) were no significant differences between the control and SWD treatment groups. $L^{\ast}$ and $b^{\ast}$ value of meat color were decreased as the storage period passed There was a not significantly difference in shear force value among control and SWD treatment groups. Shear force value was decreased significantly during storage in all treatment groups. In all results, dietary SWD-supplementation was not affected in general components, texture characteristics and physico-chemical properties. It is suggested that dietary SWD-supplementation could produce of high quality pork.

Objectives : This study was peformed to identify the risk factors related to the development of hypertension in a rural area. Method : Total of 3,573 subjects in Chung-Song County were interviewed and examined in 1996. The study cohort comprised 2,580 hypertension-free subjects aged above 20. One-year follow up was completed for 1,781 subjects(69.0%) in 1997. General characteristics(age, gender, education level, economic status, marital status), the family history of hypertension, diet, alcohol, smoking, coffee, stress, past history of oral contraceptive and menopausal status in female, height, weight, waist and hip circumference, baseline blood pressure, and serum total cholesterol were considered as risk factors. Results : Multivariate analysis using logistic regression model indicated that age(RH=1.50, 95% CI; 1.15-1.96), the family history of hypertension(RR=2.11, 95% CI; 1.04-4.26), waist-hip ratio(WHR) (RR=2.09, 95%, CI; 1.15-3.79), and baseline systolic blood pressure(130-139/<120mmHg)(RR=3.34, 95% CI; 1.47-7.60) were significant risk factors associated with the development of hypertension above the borderline level in male. In female, age(RR=1.06, 95% CI; 1.03-1.09), change in menopausal status$(no{\rightarrow}yes/no{\rightarrow}no)$ (RR=3.32, 95% CI; 1.01-10.87), baseline systolic blood pressure(120-129/<120mmHg: RR=2.00, 95% CI; 1.02-3.90)(130-139/<120mmHg: RR=2.64, 95% CI; 1.34-5.20) and baseline diastolic blood pressure(85-89/<80mmHg)(RR=4.09, 95% CI; 1.86-8.96) were identified as risk factors. Conclusions : Age and high normal blood pressure were significant risk factors for the development of hypertension above the borderline level. In addition, the family history of hypertension and WHR in men, and the change of menopausal status in women might be significant risk factors in Korea.

The effects of diet composition, reproductive condition and ketonuria and ketosis on the composition of rumen volatil fatty acids(VFA) and the blood lipid concentration were investigated in Holstein dairy cows. Six healthy cows(Group I), 9 ketonuric cows (Group II) and 8 ketotic cows(Group III) were examined at days 13-15 pre-partum(PRP) and at day 15 post-partum(POP). The ratios of concentrated feed supplied at PRP and POP were 0% and 15%, respectively, in Group I, 25% and 67% in Group II, and were 30% and 46% in Group III. The fulfillment rates of total digestive nutrient(TDN) and digestive coarse protein(DCP) increased at POP in each group. Although total VFA concentrations were lower at POP than at PRP in each group, the concentrations at PRP and POP were higher in Group I than in Groups II and III. The molar ratio of acetic acid decreased at POP in Group I, while the ratio increased at POP in Groups II and III. The molar ratio of propionic acid increased at POP in Group I, while it decreased in Groups II and III. Blood total cholesterol, free cholesterol, cholesterol esters, HDL-cholesterol, phospholipid and free fatty acid concentrations decreased at POP in all three groups, but these levels were low in Group I, high in Group III and intermediate in Group II at PRP and POP. Triglyceride concentration decreased after parturition in these three groups, but the decrease was most striking conspicuous in Group III.

Purpose: This study was carried out to investigate the awareness of the weaning of food using questionnaires, and the relationship with the weight gain in young infants. Methods: From September 2005 to December 2005, we performed a survey on 141 guardians of young infants aged from 6 to 18 months, who visited the pediatric out-patient department at Dongguk University Medical Center. We calculated the total score for each responder from ten questions on the weaning of food and assessed the body weight percentile of each of the young infants. Results: The most commonly reported information source for weaning food was 'the friends around' by 62 respondents (44.0%); 54 (38.3%) responded that the definition of weaning food was the preparatory step before starting a solid diet. Most used a spoon (90.8%) to feed when weaning food with a thin gruel of rice (78.7%). The time for weaning of food was before breast or infant formula feeding (55.3%). Addition of cow's milk was around 12 months (77.3%). The mean score was 6.21; however this did not show a statistically significant correlation with weight gain in young infants. Conclusion: The overall awareness of weaning of food has improved; however, information from doctors has decreased. Although the relationship between the awareness of weaning of food and the growth of young infants was not statistically significant, further studies on weaning of food, with larger and controlled sample sizes may provide important information.

This study investigated the effects of silkworm droppings(SWD) added diet feeding on chemical composition of pork loin meat. Pigs were divided into 7 treatment groups(10 pigs/group) and subjected to one of seven treatment diets(O, 1 0/0, 2 0/0, 3% SWD for 4 weeks, 1 0/0, 2 0/0, 3% SWD for 8 weeks, SWD diets; total fed diets) before slaughter. Pork loin were collected from the animals(1l0 kg body weight) slaughtered at a commercial slaughter house. Pork loin meat were aerobic packaged and then stored at$4^{\circ}C$ for 2, 5, 8, or 12 days. Samples were analyzed for TBARS, sensory evaluation, myoglobin content, fatty acid composition, amino acid and mineral content. TBARS value was not significantly different between the control and SWD treatment groups. Myoglobin content of SWD fed group pork was significantly increased than that of control group(P<0.05). Marbling score and acceptability were increased in SWD fed pork compared to those in control pork. Na, Mg, Ca, Mn and Fe content of SWD fed group pork was significantly decreased than those of control group(P<0.05). P content was significantly increased than that of control group(P< 0.05). In the change of amino acid composition, the contents of aspartic acid, serine and tyrosine were decreased by dietary SWD-supplementation, whereas the SWD-supplementation resulted in the higher glutamic acid, alanine and isoleucine. As dietary SWD was increased in feed, the content of oleic acid was significantly increased, but stearic acid was significantly decreased(P<0.05).

This study was conducted to investigate the bioavailability of starfish calcium with substances enhancing calcium absorption. Three week-old young female rats (Sprague-Barley) were divided into 5 groups according to calcium sources and testing agents; calcium carbonate (C), starfish calcium (S), starfish calcium + casein phosphopeptide (S-CPP), starfish calcium+citrate-malate (S-CM), starfish calcium+isoflavone (S-ISO), and were fed experimental diets containing AIN-93G based Ca (0.35% w/w) diet with CPP, CM and ISO for 6 weeks. Blood, femur, urine and feces samples were collected. There was no significant difference among groups in terms of growth and food intake. Serum Ca concentrations were normal in all 5 groups. Serum P concentrations and ALP activities were not significantly different among groups. Ca absorption and retention were significantly increased both in S-CPP and S-CM groups compared to C group (p<0.05). p absorption was significantly higher in S-CPP group than in other groups. While the amount of soluble Ca of intestinal contents did not differ among groups, the amount of insoluble Ca was significantly lower in S-CPP, S-CM and S-ISO groups than in C and S groups. However, the weight, Ca and P concentrations of femur were not significantly different among groups. These results suggest that the addition of CPP and citrate-malate were more effective for enhancing the bioavailability, intestinal absorption and solubility of starfish calcium.

Objectives: This study was to evaluate the compliance of hypertensive patients and its related factors registered at Community Health Practitioner Post(CHCP). Methods: 304 patients were interviewed by trained nursing students during one month(June~July 2004). The questionnaire included general charactristics, knowledge of hypertension, health education experience, constructs of Health Belief Model, self efficacy and so on. Compliance group was defined "having regularly medication and good life style". Good life style included regular exercise, non-smoking, little alcohol, low salt diet, weight control. Results: In compliance group 90.3% of man and 93.3% of woman were regularly taking hypertensive medicine, and 45.2% of man and 56.4% of woman were having good life style (compliance group). In both man and woman, the group of higher education were more compliance group, but were statistically significant were in man(p<0.05). In woman, the compliance group have significantly higher score in knowledge of hypertension(p(0.05). The compliance group have significantly higher self-efficacy score in both man and woman (p<0.05). In Health Belief Model, susceptibility and benefit were statistically significant in man, seriousness, benefit and barrier in woman(p<0.05). In multiple logistic regression analysis, education level and self efficacy in man and knowledge of hypertension, self-efficacy and benefit in woman were significant variables (p<0.05). Conclusions: It is very important to evaluate and modify life-style adding to having regularly medication in hypertensive patients registered at CHCP. To this, health education programs about benefit to compliance and the methods to improve self-efficacy should be developed for this patients.

As rapid progress of population aging and strong interest in health, the demand for new healthcare service is increasing. Until now healthcare service has provided post treatment by face-to-face manner. But according to related researches, proactive treatment is resulted to be more effective for preventing diseases. Particularly, the existing healthcare services have limitations in preventing and managing metabolic syndrome such a lifestyle disease, because the cause of metabolic syndrome is related to life habit. As the advent of ubiquitous technology, patients with the metabolic syndrome can improve life habit such as poor eating habits and physical inactivity without the constraints of time and space through u-healthcare service. Therefore, lots of researches for u-healthcare service focus on providing the personalized healthcare service for preventing and managing metabolic syndrome. For example, Kim et al.(2010) have proposed a healthcare model for providing the customized calories and rates of nutrition factors by analyzing the user's preference in foods. Lee et al.(2010) have suggested the customized diet recommendation service considering the basic information, vital signs, family history of diseases and food preferences to prevent and manage coronary heart disease. And, Kim and Han(2004) have demonstrated that the web-based nutrition counseling has effects on food intake and lipids of patients with hyperlipidemia. However, the existing researches for u-healthcare service focus on providing the predefined one-way u-healthcare service. Thus, users have a tendency to easily lose interest in improving life habit. To solve such a problem of u-healthcare service, this research suggests a u-healthcare recommender system which is based on collaborative filtering principle and social network. This research follows the principle of collaborative filtering, but preserves local networks (consisting of small group of similar neighbors) for target users to recommend context aware healthcare services. Our research is consisted of the following five steps. In the first step, user profile is created using the usage history data for improvement in life habit. And then, a set of users known as neighbors is formed by the degree of similarity between the users, which is calculated by Pearson correlation coefficient. In the second step, the target user obtains service information from his/her neighbors. In the third step, recommendation list of top-N service is generated for the target user. Making the list, we use the multi-filtering based on user's psychological context information and body mass index (BMI) information for the detailed recommendation. In the fourth step, the personal information, which is the history of the usage service, is updated when the target user uses the recommended service. In the final step, a social network is reformed to continually provide qualified recommendation. For example, the neighbors may be excluded from the social network if the target user doesn't like the recommendation list received from them. That is, this step updates each user's neighbors locally, so maintains the updated local neighbors always to give context aware recommendation in real time. The characteristics of our research as follows. First, we develop the u-healthcare recommender system for improving life habit such as poor eating habits and physical inactivity. Second, the proposed recommender system uses autonomous collaboration, which enables users to prevent dropping and not to lose user's interest in improving life habit. Third, the reformation of the social network is automated to maintain the quality of recommendation. Finally, this research has implemented a mobile prototype system using JAVA and Microsoft Access2007 to recommend the prescribed foods and exercises for chronic disease prevention, which are provided by A university medical center. This research intends to prevent diseases such as chronic illnesses and to improve user's lifestyle through providing context aware and personalized food and exercise services with the help of similar users'experience and knowledge. We expect that the user of this system can improve their life habit with the help of handheld mobile smart phone, because it uses autonomous collaboration to arouse interest in healthcare.
