In this study, the effects of corn peptide consumption on plasma lipid profiles were investigated in high cholesterol diet-fed rats. Male Sprague-Dawley rats (n = 21) were fed with corn peptide-free (control) diet, diets containing 2% or 5% com peptide for 5 weeks. Hypercholesterolemia was induced by adding l% cholesterol and 0.5% cholic acid to all diets. No difference was found in food intake and body weight gain among groups. The corn peptide treated groups showed significant improvement in the plasma level of HDL-cholesterol (p<0.05) compared to the control group, while the plasma total cholesterol and LDL-cholesterol were not affected.5oio corn peptide supplemented diet reduced plasma level of triglycerides (p<0.05) The atherogenic index was decreased in the corn peptide treated groups. These results suggest that consumption of corn peptide may lead to an amelioration of metabolic syndrome as well as a reduction of cardiovascular disease and hyperlipidemia through increasing the level of HDL-cholesterol, and decreasing the level of triglycerides in plasma.

We proposed a new cross-coupled level shifter circuit using low temperature poly-Si(LTPS) TFT. The proposed level shifter can operate on low input voltage in spite of low mobility and widely varying high threshold voltage of LTPS TFT. Also, the proposed level shifter operates at high frequency and reduces power consumption for having fast rising and falling time and shortening period flowing short-circuit currents.

It is necessary to determine the current and future energy consumption by farm households for the rational specification of energy related policy in the Korean agricultural sector. Especially, It is important to identify the consumption by source of energy and by the crops. On the other hand, the world has tried to reduce the production of greenhouse gases and, in line with this, the Korean government established related legislations to contribute to this reduction (30% reduction in emissionsby 2020). The reduction target of the agricultural sector is specified as 5.2% of the national total. This study focuses on sampling design to determine the energy consumption and emission of greenhouse gases, and suggests several alternatives to improve the confidence level and to make a dent survey and estimation errors. The population for the energy consumption survey of the agricultural sector was derived from agricultural census data. In the case of commodities with high skewness, we cut the sample range to within the statistical significant range. The number of samples in each class is specified using the Neyman allocation method and 95% significance level. The estimation results are compared with the population to verify the statistical significance and several management methods of sampling errors are suggested.

In the real world, there exist various products in terms of price and quality, and it can be expected that a product with lower price and higher quality than others is better. Hence efficiency of consumption behaviour can be measured by the level of goodness in terms of price and quality attributes of that product. The purpose of this research is to define consumption efficiency in terms of price and quality, and to measure consumption efficiency of IT and electronic products in South Korea. From the results, many consumers have purchased inefficient products m air-conditioner, TV, digital camera, MP3 player, computer markets. On the other hand, consumers have purchase efficient products in refrigerator and washing machine markets relatively. In addition, we analyze the relationship of consumption efficiency, information channel, and electric power consumption. This research may provide meaningful information for consumer's behaviour by measuring consumption efficiency quantitatively.

We surveyed 837 students attending elementary schoolchildren in Korea for health functional foods (HFF) consumption and significant variables for their HFF consumption including demographic characteristics, parental health concern on offsprings, food eating frequency of subjects and beliefs on potential efficacy of HFF by subjects. The consumption prevalence of HFF was 45.9%, and among all types of HFF, nutritional supplements were taken most frequently, followed by apricot extract-fermented products > lactic acid bacteria containing products > EPA/DHA containing products > red ginseng products. HFF consumption was higher in subjects had parents of high education level (p < .05) and those from families with a high socioeconomic status (p < .01) in comparison to each corresponding group. Health concern on offsprings by parents (p < .001) and consumption ratio of HFF by family (p < .001) was higher in consumers than in nonconsumers of HFF. Total score of dietary assessment was higher in consumers than in nonconsumers of HFF (p < .01), and consumers had a more positive view concerning the potential efficacy of HFF than did nonconsumers (p < .001). Most consumers of HFF took HFF when they were healthy (42.5%), and they did not feel special effects through HFF consumption (47.7%). Most consumers of HFF got the information on HFF from family and relatives (24.8%), and most of them purchased HFF at pharmacy or oriental medicine clinics (53.9%). HFF consumers preferred multi-vitamins and Ca-supplements most among the vitamin mineral supplements belonged to HFF. Given the widespread consumption of HFF by elementary schoolchildren, the reasonable consumption of these products for the contribution to their overall health and well-being should be emphasized through nutrition education for them and their family.

The purpose of this study is to analyze the pattern of tenant layout for selected cases of five different Urban Entertainment Center(UEC) in Seoul. This research deals with the process of gaining tenant layout pattern of 40 different types. It is composed of three combination unit with tenants of the same or different consumption mode, which is divided into four different functions of retail, entertainment, dining, and service. Then, every tenant of research cases is classified as one of the fabric type, and the data is analyzed to gain its frequency rate with SPSS 14.0 program. The following is the overall explanation of the result for this research. The frequency of tenant layout pattern between the same consumption mode shows the high rate when compared to the other patterns with different consumption mode. For example, the frequency rate of tenant layout pattern which retail and dining consumption mode are placed side by side like RRR and DDD is high. Interestingly, the frequency rate of RRR type of tenant layout pattern that sells the similar products shows especially high level. It can provide the effective environment for shoppers to compare retail goods in many different stores as producing synergic effects when they are located near each other, so this strategy should be considered when planning tenants in UEC environment. Moreover, in case of dining tenants, when they are clustered together in the UEC environment it can play a role as an anchor tenant. Tenant layout pattern of dining-retail and dining-service consumption mode shows the high frequency rate than other layout pattern with other consumption mode. Besides, entertainment consumption tenants combined with dining or retail tenants show the high frequency rate when compared to the pattern combined with service consumption mode.

This paper is to analyze the past and present consumption pattern of fishes aquacultured in marine waters and thus to draw the policy direction to enhance the competitiveness of marine fish aquaculture in Korea. At present, the volume of meat consumption is surveyed to be more than that of marine fish, but it is revealed that fish consumption will become more increasing in the future according to the rise of the income. The survey shows that the consumption of fish is highest in the fall, and among the various patterns of consumption, live fish, so-called susi, is surveyed to be highly dominant. It is revealed that fish is enjoyed because of the special savor, diverse nutrients, and the prevention of adult diseases. Natural fish Is revealed to be more preferred to aquacultured one due to the sticky flesh quality and the low probability of the remained after the production process antibiotics, so that it is necessary to enhance the taste quality and make a clean cultivation to capture more market demand. Consumption of high-quality fish seems to become high in more than middle class and consumption of fish are estimated to increase in the future, more than that of meat if income level of the people increases. Also, if we try to make our high-quality fish become popular among the public and competible with the imported fish from abroad, it is recommended that they must lower production price by cost reduction and try to differentiate it by taste and environmental safety, etc. It was revealed that the significant factor in demand function for fish is income and it is almost the only factor affecting that demand. Also, it was revealed that the most significant factor affecting preference of fish is income and it Is almost the only factor affecting the preference. Therefore, we can ascertain that if proper goods can be distributed, demand for and preference of fish may increase according to the increase of income in the future.

BACKGROUND/OBJECTIVES: This study aimed to assess the current mean daily intake of 10 food groups, analyze the sociodemographic factors associated with food consumption, and determine the associations between food consumption/dietary intake and the prevalence rates of obesity, type 2 diabetes (T2D), and hypertension (HTN) in Jakarta, Indonesia. SUBJECTS/METHODS: A total of 600 participants aged 20-85 yrs were included in this cross-sectional study. Food consumption and dietary habits were assessed using a food frequency questionnaire. To determine the association between food consumption/dietary habits and the abovementioned diseases, logistic regression analysis was performed. RESULTS: The average vegetable and fruit intake was lower, while sugar and salt consumption were higher than that recommended by Indonesia's national dietary guidelines. A high intake of ultra-processed foods (UPFs) was associated with young age, men, "single" status, a high education level, and employment with a high monthly income. Obesity and T2D were positively correlated with high intakes of cereals and tubers, UPFs, sugars, fats, and oils. Conversely, an inverse association was found between legume, vegetable, and fruit consumption and obesity risk. An inverse correlation was also observed between vegetable consumption and T2D risk. Moreover, a high salt intake was inversely correlated with fruit consumption in terms of HTN risk. Non-indulgence in habitual late-night snacking and refrainment from consuming more than one dish at each meal were also negatively related to the prevalence of obesity, T2D, and HTN. Inverse correlations were also observed between the prevalence rates of T2D and HTN and abstaining from adding sugar to beverages. CONCLUSION: Foods high in fat, sugar, and sodium were strongly associated with the risks of obesity, T2D, and HTN. Additionally, poor eating habits were also associated with disease development.
