Nowadays, the user-centric application based web 2.0 has replaced the web 1.0. The users gain and provide information by interactive network applications. As a result, traditional approaches that only extract and analyze users' local document operating behavior and network browsing behavior to build the users' preference profile cannot fully reflect their interests. Therefore this paper proposed a preference analysis and indicating approach based on the users' communication information from MicroBlog, such as reading, forwarding and @ behavior, and using the improved PersonalRank method to analyze the importance of a user to other users in the network and based on the users' communication behavior to update the weight of the items in the user preference. Simulation result shows that our proposed method outperforms the ontology model, TREC model, and the category model in terms of 11SPR value.

The purpose of this study was to investigate influences on wives' financial management behavior economic instability and coping behavior of urban household. Economic instability was constructed with an objective economic status and perceived economic instability. And, Financial management behaviors were constructed with four dimensions : investment, income/expenditure, risk, and debt management behavior. The subjects of this study were 225 housewives. Factor analysis, Cronbach ${\alpha}$, and multiple regression were performed for data analysis. The results show that, coping behaviors of searching and using information and perceived economic hardship related to debt influenced housewives' investment management behaviors. The coping behaviors of searching and using information, expending in the range of planned budget, using debt, perceived economic hardship related to debt, income insufficiency, and selective expenditure influenced the consumption-expenditure management behaviors. Perceived economic hardship related to essential expenditures and coping behaviors of searching and using information influenced the risk management behaviors. Coping behaviors of searching and using information, using debts and purchasing and using economically, and perceived economic hardship related to essentials influenced debt management behaviors.

NFPs support a sustainable society and they rely on contributions from donors. Donor behavior is a kind of consumer behavior that influences fundraising by NFPs. In order to make fundraising functional under a principal-agent relationship, NFPs must construct trust through proper provision of accounting information. For donors, financial statements are main source of accounting information. Edelman revealed that the level of trust in Japan's NFPs is the lowest in East Asia, because of a lack of transparency and accountability. Some researchers had investigated donor behavior as a kind of consumer behavior and had provided supportive results that accounting information influences donor behaviors, before this research was conducted. This research investigates this background by conducting questionnaire-based survey. Main questions of this questionnaire were created according to criteria that BBB are using for NFPs in the U.S. The results of this survey revealed the lack of reliability of basic accounting information in Japan and that education in higher educational institutions can improve this situation. This survey also revealed that a rating agency like BBB, which evaluates accounting information of NFPs, could improve trust on NFPs. The implications of this study can apply to the other countries and regions where trust in NFPs is insufficient.

Fashion store patronage behavior includes, in broad, choosing of a store and strong preference of a certain store called store-royalty. Thus, in order to achieve successful business in sales, a retailer must continually analyze why target consumers choose particular stores and patronize them. This study identified the relevant factors of the patronage behavior of female college students residing in Seoul. Thus, this study can achieve its goal of enabling retailers to predict use information sources used by the target consumers, so that help retailer to establish new positions of their shops to differentiate them from others and, also, to reposition existing stores. The aims of this study were to classify information sources used by female college students and identify the relationships between them and fashion store patronage behavior. Relationship between the factors of information sources and patronage behavior were identified by use of Tukey's test, Duncan test and ANOVA. As a result, it showed significant differences among patronage groups according to nearly every factor of information sources used by female college students. As based on the results, this study is expected to assist that retailers can establish effective sale strategies in order to make continuously consumers' patronage behavior of a store.

Emerging attacks aim to access proprietary assets and steal data for business or political motives, such as Operation Aurora and Operation Shady RAT. Skilled Intruders would likely remove their traces on targeted hosts, but their network movements, which are continuously recorded by network devices, cannot be easily eliminated by themselves. However, without complete knowledge about both inbound/outbound and internal traffic, it is difficult for security team to unveil hidden traces of intruders. In this paper, we propose an autonomous anomaly detection system based on behavior profiling and relation mining. The single-hop access profiling model employ a novel linear grouping algorithm PSOLGA to create behavior profiles for each individual server application discovered automatically in historical flow analysis. Besides that, the double-hop access relation model utilizes in-memory graph to mine time-sequenced access relations between different server applications. Using the behavior profiles and relation rules, this approach is able to detect possible anomalies and violations in real-time detection. Finally, the experimental results demonstrate that the designed models are promising in terms of accuracy and computational efficiency.

The purpose of this study was to develop strategies and policies for smoking prevention that are tailored to the characteristics of different groups of smokers. The structured survey was conducted with regular smokers. The results were as follows: It has been demonstrated that Risk Perception Attitude framework can be used as a major research framework to predict behavioral changes related to the prevention of smoking. The smokers were divided into four attitude groups based on perceived risks and self-efficacy: indifference, proactive, avoidance, and responsive. The smoker groups showed significant differences in information seeking, information avoidance, prevention behavior and addiction degree. Especially, the difference in prevention behavior depended on the self-efficacy when the perceived risk level was high. Information avoidance was the lowest when the perceived risk level was high and the self-efficacy was low. Information seeking was lowest when the perceived risk level was low. When the level of self-efficacy was high, if the perceived risk level was high, prevention behavior was actively performed. Therefore, the self-efficacy was related to preventive behavior, and the perceived low-risk played a role in hindering information seeking. Smoking prevention strategies are important to raise awareness of the risk of smoking and to improve the positive willingness of smokers to quit smoking through self-efficacy.

The purposes of this research are, first, to investigate the present condition of indoor thermal environment in winter. Second, to find out how residents' knowledge, consciousness, and behavior changed after provided with education and information of indoor climate. Finally, to reveal how this changes make alteration to their indoor environment. Thirty apartments were collected, and then divided into three groups as Control Group, Education Group, and Edu-information Group in order to conduct the purposes. Provided education and environmental information turn out to have a positive effect to residents' knowledge, consciousness, and behavior, and consequently, it leads residents to control their indoor environment more actively in some cases. Thus, it is important to provide residents with environmental education and information, and it should be conducted regularly in order to maximize the positive effect of education since it tends to decrease as time goes by.

The purpose of this study is to evaluate consumer use of unit price information introduced in Korea 1999. A total of 571 observations were analyzed by frequency, percent, and paired t-test using SPSS. The main findings are (1) consumers use unit price information to make better purchase decisions, (2) consumers with higher than average attentiveness in purchase behavior utilize unit price information to make better buying decisions, and (3) consumers with higher than average knowledge utilize unit price information to make better buying decisions. (4) Also if either attentiveness in purchase behavior or consumer knowledge is lower than average, unit price information helped consumers make better purchase decisions. (5) However, there was no difference among those consumers with below average or above average attentiveness and knowledge.

When a SAR system operates in a full-polarimetic mode, the amount of the information one can extract is so complex that the effective presentation of the information is important. However, the information acquired from the polarimetric SAR data is often difficult to interpret by itself, because it is consisted of both the amplitude information and the phase information. Polarimetric parameters are the good way of representing the polarimetric SAR information in a quantitative manner. Also they can characterize the scattering behavior of the ground scatterer. In this research, extraction of polarimetric parameters, evaluation and interpretation of the scattering behavior of the ground with respect to polarimetric SAR signal are carried out. Using the NASA/JPL AIRSAR data, we estimated the polarimetric parameters and compared them in terms of the ground features. In general, extracted parameters well represent the characteristics of the different features on the ground.
