The purpose of this study was to compare nutrient intake, health-related factors, and risk factors for metabolic syndrome and to investigate the prevalence odds ratio according to fruit and vegetable intake among middle-aged Korean men. Subjects included 1,677 men aged 40 - 64 years. The average intake of fruits and vegetables was $578.48{\pm}5.90g/day$. Forty-nine percent of the subjects were categorized into the deficient group based on the intake of fruits and vegetables, and the other subjects were categorized into the adequate group. There was a significant difference in the nutrient density per 1,000 kcal of energy, minerals, vitamins, and dietary fiber between the fruit and vegetable intake groups (p<0.001). In terms of health-related factors, only the current smoking rate in the deficient group (57.9%) was higher than that in the adequate group (45.4%) (p<0.001). There was no significant difference in the risk factors for metabolic syndrome between the fruit and vegetable intake groups. Proportion of serum triglycerides (42.6%) was the highest at a rate that exceeded the criteria for risk factors for metabolic syndrome, but systolic blood pressure (21.7%) showed a very low rate. The fasting blood glucose, serum triglycerides, and diastolic blood pressure were significantly higher in the deficient group than in the adequate group (p<0.05). Prevalence of metabolic syndrome was 31.2%. OR for prevalence of metabolic syndrome related to fruit and vegetable intake was 1.270 times higher in the deficient group than in the adequate group (p<0.05). Also, when the daily fruit intake was increased by 100 g, the prevalence of metabolic syndrome was reduced by 0.948 times but it was not related to the vegetable intake. The results of this study can be used as the basic data to establish the guidelines for fruit and vegetable intake for prevention of metabolic syndrome in middle-aged men.

Sample presentation, which means how to set samples to an NIR instrument, is very important in Near Infrared (NIR) Spectroscopy. When sample presentation is not suitable for the samples that you use, very good spectra can not be obtained even if you use a sophisticated NIR instrument. In my presentation, various NIR sample presentations for agricultural products such as intact fruits, single grains, vegetable juice and the others will be explained. In case of peaches with thin peel, the fiber optics of Interactance can be used. However, the fiber optics are not suitable for oranges with relatively thick peel. In this case, transmittance method is useful. As for a small sample such as single grains, a specially designed cell is needed. The cell in transmittance mode has been developed and then applied to single kernels of rice and soybean. In this case we also used the fiber optics. As regards liquid type of sample, a cuvette cell made of quartz in transmittance mode is popular. However, it is time-consuming to wash and dry it. In order to compensate this disadvantage the sample presentation using normal test tubes as sample cells have been developed and applied to milk, rumen juice and urine of a milking cow. An individual test tube can be used for each sample if you use the calibration equation with sample cell compensation. The test tube cell has also been applied to spinach juice for determination of undesirable constituents. It is concluded that sample presentation is most important for NIR Spectroscopy.

In the 21^st century, the demand for eco-friendly leather, such as eco-leather and vegan leather, is steadily increasing. This study examines the influence of eco-friendliness on consumers' purchasing intentions and the possibility of eco-friendly changes in the fashion accessory market, which is dominated by leather material and leather substitutes. This study administered a questionnaire survey to 227 males and females between 20 and 60 years of age in Korea. With a 5-point Likert scale, data were collected on evaluation criteria when purchasing shoes and bags and purchasing intention of various leather substitute materials according to the democratic variables. The eco-friendliness attitude was divided into eco-consciousness and green behavior. As the eco-friendly attitude increased, most purchasing standards increased, but the purchasing criteria, such as trends, brands, and prices, did not correlate with the eco-friendly attitude. The eco-consciousness of a consumer had a high correlation with the design evaluation criteria, while the green behavior of the consumer aligned with durability and comfort criteria when purchasing a bag. There was a preference for recycled leather, vegetable leather, synthetic leather, and chemical leather, and the fabric type was ranked as natural fiber, biodegradable fiber, and synthetic fiber. Consumers with both green behavior and eco-consciousness are more likely to purchase biodegradable textiles and vegetable leather for the material of shoes and bags.

Response surface methodology was used to study the effect of egg albumen (5-15 g), vegetable oil (5-15 g), and corn bran (5-15 g) on sensory and textural (firmness and toughness) quality of chicken nuggets cooked by the oven, steam, and microwave methods. The egg albumen and vegetable oil had a positive linear effect but corn bran had a negative linear effect at p<0.01 on sensory overall acceptability scores of nuggets. Firmness and toughness scores were increased significantly (p<0.01) with the increase in corn bran level in the formulation. The optimum level of egg albumen, vegetable oil, and corn bran were obtained and validated. Cooking methods also affected the sensory and textural quality of nuggets. Steam cooked nuggets had higher values of sensory scores than oven and microwave cooked nuggets. Oven cooked nuggets showed higher values of firmness and toughness than steam and microwave cooked nuggets. Results of this study suggest that emulsion based meat products can be enriched with dietary fiber source like corn bran without compromising the sensory and textural quality of the products.

This study was conducted to analyze dietary fiber content of 113 common Korean foods. Content of total dietary fiber(TDF) in vegetables, mushrooms, fruite, and seaweeds was determined by enzymatic-gravimetric method developed by Prosky et al. and adopted by AOAC. The average TDF content of the foods analyzed was 3.62$\pm$2.09% for green vegetables, 5.90$\pm$7.61% for light vegetables, 14.27$\pm$18.11% for mushrooms, 3.02$\pm$4.48% for fruits, and 11.39$\pm$12.68% for seaweeds. The foods containing the highest TDF values in the food groups were boiled radish leaves(10.84%) in green vegetables, dried braken(38.36%) in light vegetables, dried juda's ear(18.18%) in mushrooms except dried manna lichen(52.87%), dried persimon(17.73%) in fruits and dried sea mustard(37.77%) in seaweeds. Dried Seaweeds such as sea mustard (37.77%), sea tangle(29.30%), and laver(31.36%) were good sources of dietary fiber. When we consider the health and therapeutic benefits of dietary fiber, it is recommended to continue to consume traditional Korean diet which are mainly composed of vegetables rather than animal foods and to increase consumption of dried mushrooms and seaweeds which contain high content of TDF.
