The Decomposition of NO$_2$ (nitrogen dioxide), one of the Hazardous Air Pollutant (HAP), was studied by utilizing the SPCP (Surface induced discharge Plasma Chemical Processing) reactor so as to obtain optimum process variables and maximum decomposition efficiencies. Experimental results showed that for the frequency of 10kHz, the highest deco position efficiency of 84.7% for NO$_2$ was observed at the power consumptions of 20W. The decomposition efficiency of $NO_2$ was found to be: 1) proportional to the residence times, and inversely proportional to the initial concentrations of $NO_2$; 2) the maximum when the electrode diameter was 3mm; 3) influenced by the electrode material, decreasing in the order of W>Cu>Al; and 4) proportional to the $CH_4$ content, due to which the highest efficiency of 98% was obtained with almost all the $NO_2$ removed.

This study was undertaken to determine talc fatty acid intakes of lactating women and breast fed infants. Food consumptions of lactating women were measured at 3 4nd 9 days find 4, 8 and 12 weeks postpartum, respectively and diet samples were collected at the same time. Breast milk and blood samples were collected at 12 weeks postpartum. Fatty acid profiles of diet and breast milk were analyzed with GC. Total fatty acid intakes, fat percentage of energy, P/M/S and n-6/n-3 ratios of lactating women were 50.7 g/d, 20.9$\%$, 0.6/0.9/1 and 4.0/l, respect timely, over the first 12 weeks of postpartum and were not significantly different according to the lactating stages. Total fatty acid intakes and fat percentage of energy of the infects aged 12 weeks through the breast milk alone were 18.9 g/d and 44.8. This study shows that the linoleic acid percentage of energy intake in infants was 6.7$\%$, which was in optimum and/or high level to generally recommended guideline. DHA intakes of lactating women were positively correlated with those of infants from breast mil.

The purpose of this study was to find out the shopping motive factors of clothing and to classify consumer groups according to clothing shopping motives, and also to analyze demographic characteristics, conspicuous consumption and clothing purchase behavior among consumer groups. The subjects were 329 women in their twenties living in Seoul. For data analysis, mean, Factor Analysis, Cluster Analysis, $\chi$$^2$-test, ANOVA, Duncan test were conducted. The results are as follows; 1. Three factors of clothing shopping motives were identified: fashion/leisure pursuit, economic, and personal motive. Consumer groups are classified into the following four subdivisions: personalizing group, apathetic group, fashion/leisure pursuit group, economic group. 2. Among consumer groups, there were significant differences in demographic characteristics according to age, occupation of the subjects. 3. Among consumer groups, there were significant differences in conspicuous consumptions according to factors such as brand intention, status symbol intention. 4. Among consumer groups, there were significant differences in clothing purchase behavior according to use of information sources. Regardless of clothing shopping motives, consumer preferred department stores in purchasing formal dress, and preferred haberdashery.bonded store in purchasing casual wear.

This study investigates the effect of demographics and materialism on the consumers's attitudes and clothing purchase behaviors. The subjects compose of 302 college students living in Yunnam, China. The mean, ANOVA, factor analysis, Duncan test were used for statistics analysis. According to our results, the factors of materialism, symbolic consumptions, and attitude toward fashion luxury products are identified: three factors of materialism (success symbols, practical living, and happiness pursuing), three factors of symbolic consumption (conspicuous, hedonic, communication), and five factors of attitudes toward fashion luxury products (quality, involvement, ostentation, luxurious aspect, pleasure). Among the demographics, gender, income, social stratification, father's education and job influenced the symbolic consumption, and desire's fashion luxury products. In addition, gender, income, social stratification, father's education and job influence the clothing selection standards and the extent of using fashion informations. Lastly, symbolic consumption, attitudes toward fashion luxury products, and apparel purchasing behaviors all proven to be significantly different among the 3 groups of materialism.

A smart meter is one of the core components in Advanced Metering Infrastructure (AMI) that is responsible for providing effective control and monitor of electrical energy consumptions. The multifunction tasks that a smart meter carries out such as facilitating two-way communication between utility providers and consumers, managing metering data, delivering anomalies reports, analyzing fault and power quality, simply show that there are huge amount of data exchange in smart metering networks (SMNs). These data are prone to security threats due to high dependability of SMNs on Internet-based communication, which is highly insecure. Therefore, there is a need to identify all possible security threats over this network and propose suitable countermeasures for securing the communication between smart meters and utility provider office. This paper studies the architecture of the smart grid communication networks, focuses on smart metering networks and discusses how such networks can be vulnerable to security attacks. This paper also presents current mechanisms that have been used to secure the smart metering networks from specific type of attacks in SMNs. Moreover, we highlight several open issues related to the security and privacy of SMNs which we anticipate could serve as baseline for future research directions.

The purpose of this study was to compare the effects of soup temperature on hunger, energy, and nutrient intake. The hot meal consisted of 400 g of hot beef-vegetable soup (75$^{\circ}C$), Yubu Chobap, Bulgogi, cucumber pickle and radish pickle. The cold meal component were the same as the hot meal except 300 g of water (8$^{\circ}C$) and boiled vegctables (100 g), instead of the hot beef-vegetable soup ot the hot meal. Thirst, core temperature and blood pressure were also measured before and after consumption the test meals in a within-subjects, repeated measures design. 30 women consumed 17% more kilocalories, 13% more protein and lipid and 16% more carbohydrate in the cold meal than in the hot meal. The core temperature at the end of the test meal was higher in the hot meal than in the cold meal. Energy and nutrient intake were inversely correlated with the hunger scores within 1 hour after the hot meal, however those are not related with each other in the cold meal. So hunger feeling might be disturbed in the cold meal. It is concluded that energy and nutrient consumptions were higher in the cold meal, partly because of the distrubed hunger feeling in the cold meal.
