Metabolic syndrome is a risk factor for cardiovascular and type 2 diabetes. This study was conducted to examine the relevance between nutrition intake, meal quality, and high-sensitivity C-reactive protein in Koreans with metabolic syndrome. The 2,536 subjects, aged 19~64, who participated in 2015 National Nutrition Survey were included in this study. The 24-hour recall method was employed to analyze nutrition intake and dietary quality. Subjects were grouped into either the non-metabolic syndrome group (n=1,938) or the metabolic syndrome group (n=598). Total males and females were divided into 3 groups according to the high-sensitivity C-reactive protein (hs-CRP) level to study its relationship to metabolic syndrome and its components, including odds ratio (OR) and confidence interval (CI). Results showed the homeostasis model assessment of insulin resistance (HOMA-IR) value was higher in the metabolic syndrome group (3.37) than non-metabolic syndrome group (1.57) (p<0.001). In the Index of Nutrition Quality, males in the non-metabolic syndrome group showed higher niacin (p<0.05) than males in metabolic syndrome group. Females in the non-metabolic syndrome group had higher vitamin B1 (p<0.01), vitamin B2 (p<0.001), niacin (p<0.05), calcium (p<0.001), and phosphate (p<0.01). Female in the high hs-CRP group showed high OR in blood glucose component (OR 2.488, 95% CI: 1.269~4.879) and metabolic syndrome risk (OR 2.856, 95% CI: 1.292~6.314). Females in the middle hs-CRP group had high triglycerides component (OR 2.956, 95% CI: 1.920~4.551), compared to the low hs-CRP group. The study showed females with higher hs-CRP had a higher risk of metabolic syndrome.

This study was conducted to develop the unique native local foods of Namwon and to provide basic data needed to reinvigoratethe tourist industry and local economy. Perception and satisfaction with native local foods of Namwon were surveyed in 483 tourists (246 men and 237 women 53% visiting Namwon for the first time). Of the participants, 41.2% did not stay or eat in Namwon. Most tourists visited with other family members and spent approximately 20,000 won per capita on food. Of the foods sampled for the first time, preferred foods were (in order of preference and intention to order again) Chueo-tang, Hanjeongsik, wild edible greens-jeongsik, and black pork. The degree of food satisfaction was relatively favorable (3.54±0.08 points on a 5-point satisfaction scale), with taste being the most important factor affecting the degree of satisfaction for 92.9% of the subjects. However, willingness to revisit Namwon on the basis of the local foods was not as high as the degree of satisfaction with the foods. Insufficient information and publicity concerning Namwon local foods were cited as impediments, and suggested improvements included taste, sanitation and food-based tourism. The degree of satisfaction was higher in men than in women. Age, residence, and occupation were not related to the degree of satisfaction. But, the willingness to revisit Namwon to sample local foods was related with gender (men more willing) and occupation (public service personnel, business owners, salaried employees, professionals, and housewives more willing, in order). Women in general and housewives in particular were most critical in food assessment.

The changes in the volatile organic compounds in plum after its electron beam irradiation and storage were determined using the simultaneous distillation extraction method and gas chromatograph-mass spectrometry. There were 44, 46, 45, 47, and 38 volatile compounds in the 0-, 0.25-, 0.5-, 0.75-, and 1 kGy irradiated samples, respectively. Also, the volatile flavor components of the plum that was stored for 30 days were identified as 48, 40, 40, 39, and 40 components. The compositions of the volatile compounds of the control and irradiated samples showed a similarity after the storage. Especially, the more important volatile flavor of the plum was identified as hexanal of the C6compounds, (E)-2-hexenal and (Z)-3-hexenal. In particular, hexanal, (E)-2-hexenal, and (Z)-3-hexen-1-ol increased in all the doses, where as hexanol and (E)-2-hexen-1-ol decreased. Among the lactone compounds, γ -hexalactone, γ-octalactone, and γ-decalactone were identified during the storage period in the raw samples. Hexanonic acid and 2-hexenoic acid were not identified during the storage of the samples, and 2-methylprrole was detected only when the storage samples were irradiated at a dose higher than 0.5kGy. Therefore, it was shown that there was no effect on the variation of the volatile organic component suntil 1 kGy in the plum was irradiated with an electron beam.
