The main purpose of this study was to investigate the elements which influence the symbolic consumption in clothing. Materialism and agent of socialization have been studied and the affect of these two are also developed. The theoretical study and survey methods were used. The survey was administered to 426 women in their twenties living in Seoul and Kyungki region. SPSS packages were applied to find out the results of ANOVA Duncans multiple range tests, means, standard deviation, factor analysis, and regression analysis. The major findings of this study could be summerized as follows; First, the subordinate parts of symbolic consumption was divided into these three parts; fashion oriented consumption, brand oriented consumption, hedonic consumption. The average of hedonic consumption was higher than other subordinate parts of symbolic consumption. Second, symbolic consumption was seemed to have the differences according to materialism and its subfactors. The higher materialism indicated, the higher symbolic consumption was. Third, symbolic consumption was proven to have the differences according to agent of socialization such as reference group and mass media. The higher the influence of the reference group and mass media was, the higher symbolic consumption was. Fourth, according to the results of the regression analysis examing the relative influences of variables affecting symbolic consumption in clothing, the influence of the reference group was the most important variable. The influence of mass media and materialism was related positively to the symbolic consumption.

This study adopts organismic integration theory (OIT) to classify and contrast the predominant roles of five motivations (i.e., economic incentives, self-presentation, information acquisition, altruism, and enjoyment) in fostering three levels of behavioral engagement on brand-related social media content. This study further examines the moderating effect of personality (thinkers vs. feelers) on these relationships. The results of PLS-SEM reveal the greater impact of autonomous motivations on content consumption (enjoyment and information acquisition) and content contribution and creation (altruism and information acquisition), compared with controlled motivations (self-presentation and economic incentives). This study also finds that thinkers mostly engage on brand-related content for information acquisition and economic incentives, whereas feelers are mostly driven by enjoyment for content consumption and by altruism for content contribution and creation. This study addresses the inconsistency in prior research findings and provides practical implications to social media marketers.

The purpose of this study is to identify trends and potential themes of research on consumption of children and adolescents for 20 years by analyzing keywords. The keywords of 869 studies on consumption of children and adolescents published in journals listed in Korean Citation Index were analyzed using text mining techniques. The most frequent keywords were found in the order of youth, youth consumers, consumer education, conspicuous consumption, consumption behavior, and character. As a result of analyzing the frequency of keywords by dividing into five-year periods, it was confirmed that the frequency of consumer education was significantly higher betwn 2006 and 2010. Research on ethical consumption has been active since 2011, and research has been conducted on various topics instead of without a prominent keyword during the most recent 5-year period. Looking at the keywords based on the TF-IDF, the keywords related to the environment and the Internet were the main keywords between 2001 and 2005. From 2006 to 2010, the TF-IDF values of media use, advertisement education, and Internet items were high. From 2011 to 2015, fair trade, green growth, green consumption, North Korean defector youths, social media, and from 2016 to 2020, text mining, sustainable development education, maker education, and the 2015 revised curriculum appeared as important themes. As a result of topic modeling, eight topics were derived: consumer education, mass media/peer culture, rational consumption, Hallyu/cultural industry, consumer competency, economic education, teaching and learning method, and eco-friendly/ethical consumption. As a result of network analysis, it was found that conspicuous consumption and consumer education are important topics in consumption research of children and adolescents.

The purpose of this study is to analyze the conspicuous consumption propensity of middle schoolers and to develop effective consumer education programs which help improve consumer socialization. Empirical data were collected by using a questionnaire for 500 middle schoolers who reside in the city of Daegu. The results of this study are as follows: First, significant differences in materialistic propensity can be found. It results from the difference in parents' educational background, amount of monthly pocket money, influence of mass media and friends, and the consumer education hosted by schools. Second, significant differences in the conspicuous consumption propensity can be found. It comes from the difference in materialistic propensity and control of purchasing behaviors. Third, the variables affecting the middle schoolers' propensity of conspicuous consumption include influence of mass media and friends, control of purchasing behaviors, influence of materialistic propensity, amount of monthly pocket money, and mother's educational background. Lastly, this study helps develop consumer education programs for the teenagers. The program should use statistics data, Internet, presentation materials, putting higher priority on experience activities, survey, analysis, discussion, and presentation rather than theoretical education.

A fixed biofilm reactor system composed of anaerobic, anoxic(1), anoxic(2), aerobic(1) and aerobic(2) reactor was packed with synthetic activated ceramic (SAC) media and adopted to reduce the inhibition effect of low temperature on nitrification activities. The changes of nitrification activity at different wastewater temperature were investigated through the evaluation of temperature coefficient, volatile attached solid (VAS), specific nitrification rate and alkalinity consumption. Operating temperature was varied from 20 to $5^{\circ}C$. In this biofilm system, the specific nitrification rates of $15^{\circ}C$, $10^{\circ}C$ and $5^{\circ}C$ were 0.972, 0.859 and 0.613 when the specific nitrification rate of $20^{\circ}C$ was assumed to 1.00. Moreover the nitrification activity was also observed at $5^{\circ}C$ which is lower temperature than the critical temperature condition for the microorganism of activated sludge system. The specific amount of volatile attached solid (VAS) on media was maintained the range of 13.6-12.5 mg VAS/g media at $20{\sim}10^{\circ}C$. As the temperature was downed to $5^{\circ}C$, VAS was rapidly decreased to 10.9 mg VAS/g media and effluent suspended solids was increased from 3.2 mg/L to 12.0 mg/L due to the detachment of microorganism from SAC media. And alkalinity consumption was lower than theoretical value with 5.23 mg as $CaCO_3$/mg ${NH_4}^+$-N removal at $20^{\circ}C$. Temperature coefficient (${\Theta}$) of nitrification rate ($20^{\circ}C{\sim}5^{\circ}C$) was 1.033. Therefore, this fixed film nitrogen removal process showed superior stability for low temperature condition than conventional suspended growth process.

Objectives: The effect of meat consumption on cardiometabolic risk has been continuously studied, but their associations are not conclusive. The aim of this study is to examine the association between the consumption of meat or red meat and carotid intima-media thickness (IMT) in healthy Korean adults. Methods: This study evaluated 2374 community-dwelling adults (933 men and 1441 women) who were free of cardiovascular disease or cancer, living in a rural area in Korea. Total meat and red meat intakes were assessed with a validated 103 item-food frequency questionnaire. Carotid IMT was evaluated ultrasonographically, IMTmax was defined as the highest value among IMT of bilateral common carotid arteries. Results: After adjustment for potential confounding factors, the mean IMTmax tended to increase in higher meat consumption groups in both men and women with metabolic syndrome (p for trend= 0.027 and 0.049, respectively), but not in participants without metabolic syndrome. Frequent meat consumption (${\geq}5$ servings/week) was significantly associated with higher IMTmax in men with metabolic syndrome (by 0.08 mm, p=0.015). Whereas, the association was not significant in women (by 0.05 mm, p=0.115). Similar but attenuated findings were shown with red meat intake. Conclusions: Our findings suggest that a higher meat consumption may be associated with a higher carotid IMT in Korean adults with metabolic syndrome. The frequent meat consumption (${\geq}5$ servings/week), compared with the others, was associated with a higher carotid IMTmax only in men with metabolic syndrome. Further research is required to explore optimal meat consumption in people with specific medical conditions.

In mobile ad hoc networks(MANETs), all the nodes in a network have limited resources. Therefore, communication topology which has long lifetime is suitable for nodes in MANETs. And MANETs are exposed to various threats because of a new node which can join the network at any time. There are various researches on security problems in MANETs and many researches have tried to make efficient schemes for reducing network power consumption. Power consumption is necessary to secure networks, however too much power consumption can be critical to network lifetime. This paper focuses on energy efficient monitoring node distribution for enhancing network lifetime in MANETs. Since MANETs cannot use centralized infrastructure such as security systems of wired networks, we propose an efficient IDS node distribution scheme using minimum spanning tree (MST) method to cover all the nodes in a network and enhance the network lifetime. Simulation results show that the proposed algorithm has better performance in comparison with the existing algorithms.

The purpose of this study is to suggest that cultural consumption practices are changing with social and media changes and re-conceptualize 'cultural consumption' beyond attendance or exposure to high culture genres. We look at four types of musical consumption - news reading, posting a review, amateur participation, interaction with others - as expanded musical consumption. We expect expanded musical consumption to be closely associated with cultural capital than with attendances at musical events since high-culture events gets popularized, musical information abundant and cultural interaction easier. We explore the question of the relationship between inherited cultural capital and cultural consumption using recent survey data. More evident are positive relationships between cultural capital and production than attendance.
