Objectives: We investigated the associations of sarcopenia-defined both in terms of muscle mass and muscle strength-and sarcopenic obesity with metabolic syndrome. Methods: Secondary data pertaining to 309 subjects (85 men and 224 women) were collected from participants in exercise programs at a health center in a suburban area. Muscle mass was measured using bioelectrical impedance analysis, and muscle strength was measured via handgrip strength. Sarcopenia based on muscle mass alone was defined as a weight-adjusted skeletal muscle mass index more than two standard deviations below the mean of a sex-specific young reference group (class II sarcopenia). Two cut-off values for low handgrip strength were used: the first criteria were <26 kg for men and <18 kg for women, and the second criteria were the lowest quintile of handgrip strength among the study subjects. Sarcopenic obesity was defined as the combination of class II sarcopenia and being in the two highest quintiles of total body fat percentage among the subjects. The associations of sarcopenia and sarcopenic obesity with metabolic syndrome were evaluated using logistic regression models. Results: The age-adjusted risk ratios (RRs) of metabolic syndrome being compared in people with or without sarcopenia defined in terms of muscle mass were 1.25 (95% confidence interval [CI], 1.06 to 1.47, p=0.008) in men and 1.12 (95% CI, 1.06 to 1.19, p<0.001) in women, which were found to be statistically significant relationships. The RRs of metabolic syndrome being compared in people with or without sarcopenic obesity were 1.31 in men (95% CI, 1.10 to 1.56, p=0.003) and 1.17 in women (95% CI, 1.10 to 1.25, p<0.001), which were likewise found to be statistically significant relationships. Conclusions: The associations of sarcopenia defined in terms of muscle mass and sarcopenic obesity with metabolic syndrome were statistically significant in both men and women. Therefore, sarcopenia and sarcopenic obesity must be considered as part of the community-based management of non-communicable diseases.

Purpose: Dyslipidemia was a known risk factor for cardiovascular disease and was a leading cause of mortality in worldwide. This study aimed to determine the factors associated with prevalence and medication treatment of dyslipidemia in Korean adult population. Methods: In this study, based on the criteria set by the Korean Society of Lipidology and Atherosclerosis, the factors associated with prevalence and medication treatment of dyslipidemia was evaluated in a population of 12,506 people ($age{\geq}20$), who participated in the Korean National Health and Nutrition Examination Survey (2013-2015). The findings were tested by using multivariate logistic regression. Results: Dyslipidemia prevalence rate was 36.5%. Among populations with dyslipidemia, 17.5% were treated with lipid-lowering drugs. In the multivariate logistic regression model, male, increase in age, lower education level, non-drinker, current smoking, less physical activity, increase of body mass index, hypertension, and diabetes were associated with an increased odd of dyslipidemia. Female, increase in age, higher income, excess fat intake, hypertension, diabetes, myocardial infarction, and angina were associated with an increased odd of medication treat. Conclusion: The results of this study could be used to screen patients at the high risk for dyslipidemia or to predict medication adherence.

Objective: This study evaluated the change and function of the pancreas, and small intestine in relation to growth performance of broilers on diets supplemented with raw soybean meal (RSBM) and protease. Samples of test ingredients and diets, after mixing and prior to being used were also assessed on contents of anti-nutritional factors. Methods: A $3{\times}3$ factorial study was used, with three levels of RSBM (commercial soybean meal [SBM] was replaced by RSBM at 0, 10%, or 20%) and protease (0.1, 0.2, or 0.3 g/kg). Each treatment was replicated six times with nine birds per replicate. Birds were housed in cages, in climate-controlled room and fed starter, grower and finisher diets. Results: Levels of trypsin inhibitors in the diets, containing varying levels of RSBM ranged between 1,730.5 and 9,913.2 trypsin inhibitor units/g DM. Neither RSBM nor protease supplementation in diets significantly affected (p>0.05) the body weight of broilers in the entire periods (0 to 35-d). Increasing the level of RSBM in diets increased the weight of the pancreas at d 10 (p<0.000), d 24 (p<0.001), and d 35 (p<0.05). Increasing levels of RSBM in the diets reduced the apparent ileal digestibility of crude protein (CP), and amino acid (AA) at d 24. Increasing level of RSBM in the diets decreased (p<0.01) pancreatic protein content, but this was increased (p<0.05) when protease was added to the diets (0 to 10-d). Increasing the level of protease improved the pancreatic digestive enzymes, including trypsin (p<0.05), chymotrypsin (p<0.01), and general proteolytic enzymes (p<0.05). Conclusion: The commercial SBM could be replaced at up to 20% by RSBM for broilers. Although protease supplementation slightly improved the digestive enzymes, and the ileal digestibilities of CP and AA, the CP and AA were negatively affected by increasing RSBM.

A total of 576 seven-day-old male Ross 308 broilers with an average initial BW of $180{\pm}1g$ were used in a 4 week feeding experiment which included a starter phase (7 to 21 d) and a grower phase (22 to 35 d). Birds were randomly allocated into 1 of 3 treatments with 12 replicates per treatment and 16 birds per pen. The treatments consisted of the following: T1, Control; T2, T1 + 0.1% Creamer (Dongsuh Foods Corporation, Incheon, Korea), and T3, T1 + 0.5% Creamer. The broilers were weighed by pen and feed intake (FI) and the number of living broiler chickens were recorded on d 7, 21, and 35. These information were used to calculate the body weight gain (BWG) and feed conversion ratio (FCR). As results of this experiment, there were no significant differences in the BWG, FCR and nutrient digestibility among the treatments. With regards to meat quality, no adverse effects were observed among the treatments. However, a higher score in redness was observed in T3 than in T1. In addition, the relative weight of breast muscle was reduced in T3 compared with T1. Regardless of the nondairy creamer (NDC) inclusion levels, no negative effects on growth performance and nutrient digestibility were observed. In conclusion, non-dairy creamer could be a kind of fat sources additive in broiler diets, further studies are needed to test the optimum levels of the NDC to be supplemented in broilers diet.

Synthetic oligodeoxynucleotides (ODNs) containing unmethylated CpG dinucleotides in particular base contexts are known to induce immunity in vertebrate cells. In insect, however, it was recent to find out that ODNs induces insect immunity as other immune inducer such as lipopolysaccharide. However, the finding was solely based on one lepidopteran insect, Bombyx mori, and the expression of insect immunity was neither dependent on numbers of CpG repeats nor methylation of CpG repeats within ODNs. Instead, foreignness of DNA has been suggested to be a key factor governing induction of antibacterial peptide. In this study, we expanded our previous understanding to the potentiality of ODNs as an immune inducer for antifungal peptide in Galleria mellonella and B. mori. To do this, a defensin-type antifungal peptide gene, reported from G. mellonella was cloned and partially sequenced from G. mellonella and B. mori successfully and utilized as a probe in the Northern blot analysis. We found out that ODNs also work as an immune inducer for antifungal peptide in the fat body and midgut of G. mellonella and B. mori larvae. Also, induction pattern of antifungal peptide was irrelevant to the numbers of CpG repeats within ODNs as previously reported on the induction pattern of antibacterial peptides.

We examined the obesity levels and dietary habits of 323 college students taking the course 'Health and Diet' as a part of their nutritional education. The average percentages of body fat, BMI and RBW for subjects in this study were 16.7%, $21.5kg/m^2$ and -1.2% in male students and 27.3%, $21.2kg/m^2$ and 1.0% in female students, respectively. BMI and RBW indicated fewer cases of obesity among female students than BIA did. The average intake of energy by subjects was lower than the RDA of energy. In particular, the average intakes of calcium, iron, and vitamin A by female students were much lower than the RDA of energy. In particular, the average intakes of calcium, iron, and vitamin A by female students were much lower than the RDAs of each of those nutrients. The percent RDAs of nutrient intakes of energy, protein, thiamin, and riboflavin were lower in under weight students than in students of normal and over-weight. Female students were found to skip meals and consume sweet foods more frequently than male students. The obesity levels of students related to the number of meals eaten per day as well as the frequency of consuming sweet foods. Although, it was not possible to determine statistically, the levels obesity also seemed to correspond to the speed at which meals were eaten as well as the frequency of eating salty foods. These results suggest that in order to assess obesity properly, more research that focuses on subjects' gender should be conducted. In addition, nutritional education should emphasize the importance of intakes of energy and phosphorus for male students, and the danger of iron and calcium deficiencies for female students. We should also educate students about dietary habits which contribute to obesity such as overeating and the intake of sweet foods.

The Bombyx mori Microarray Database (BmMDB; http://silkworm.swu.edu.cn/microarray) provides information for tissue-specific gene expression by using the whole-genome oligonucleotide microarray in the silkworm. We analyzed the tissue-specific expression patterns in the silk gland, fat body, and midgut five days of fifth instar larvae during the development of B. mori. To verify the tissue-specific expression, analysis was conducted using quantitative Real-time RT-PCR and the highly expressed endogenous Actin RNA as an intrinsic reference. Finally, we confirmed five genes, (sw15872, sw00692, sw20990, sw05300,and sw2250), out of 18 candidates expressed in two different tissues, which was consistent with the data published by Dr. Xiang's group, thereby supporting the BmMDB. Further studies for promoter regions of candidate genes can be applied in creating transgenic silkworms as biomedical insects for use in producing biomaterials, and to serve as well-characterized models for understanding the mechanism for the genetic regulation of tissue-specific development.

This study was designed to compare the anti-carcinogenic effect of conjugated linoleic acid isomers on tumor incidence, cell proliferation and the levels of thromboxane (TX) B$_2$, prostaglandin (PG) E$_2$ and 1,2-diacylglycerol (DAG), and the related enzyme expression of cyclooxygenase (COX)-2 and protein kinase C (PKC) in colonic mucosa of 1,2-dimethy- lhydrazine (DMH) -treated rats. One hundred eight male Sprague Dawley rats were randomly divided into 3 groups depending on the types of CLA isomers, i.e. control group (no CLA contained), c9t11 group (cis-9, trans-11 CLA contained), and t10c12 group (trans-10, cis-12 CLA contained). The experimental diet was composed of protein at 20%, carbohydrate at 56.2%, and fat at 14.5% including 1.0% CLA isomers by weight. The experimental diet was fed for 30 weeks with the initiation of intramuscular injection of DMH, which was injected twice a week for 6 weeks to give total dose of 180 mg per kg body weight. Two CLA isomers (c9, t11, t10, c12) significantly reduced tumor incidence and cell proliferation by reducing the protein expression of COX-2 and PKC, and the level of TXB$_2$, PGE$_2$, and DAG in colonic mucosa. However, there was no significant difference in anti-carcinogenic effect between c9t11-CLA and t10c12-CLA.

This study investigated the correlations among the health consciousness, nutrition knowledge, dietary habits and nutrition attitudes of school teachers. The subjects of this study were 75 male and 152 female leachers in elementary and middle schools in Masan city. The survey was conducted by using a questionnaire. Even though the average body mass index (BMI) and the obesity index were normal in both male and female subjects, 33.3% of the male subjects were overweight/obese, while 18.5% of the female subjects were underweight, according to the obesity index. The food components of most concern during mealtime were (in order of importance) salt, MSG and cholesterol by male subjects, and salt, fat and MSG by female subjects. The subjects considered self-relaxation as the most important factor in maintaining optimal health status, followed by resting, bathing or use ova sauna, moderation in diet, exercise, decreasing alcohol intake, and no smoking. Newspapers/magazines and TV/radio were the primary sources of nutrition and health information of the subjects. As the degree of health consciousness increased, scores of the dietary habits and nutrition attitudes increased. Nutrition knowledge scores and nutrition altitudes scores increased with subjects'increased level of perception of the importance of acquiring nutrition knowledge and nutrition information. There was a highly significant correlation between the degree of health consciousness and dietary habit score (${\gamma}$ : 0.3, p<0.001). The degree of health consciousness was also significantly correlated (${\gamma}$=0.6, p<0.001) with nutrition attitudes scores. But the correlation between the degree of health consciousness and nutrition knowledge was not statistically significant. The degree of the perception of the importance of nutrition knowledge showed a positive correlation with nutrition attitude (${\gamma}$:0.4, p<0.001) and dietary habit (${\gamma}$:0.3, p<0.001). The degree of perception about the importance of nutrition knowledge and nutrition information was positively correlated with nutrition knowledge (${\gamma}$:0.2, p<0.001) and nutrition attitudes (${\gamma}$:0.3, p<0.001).
