Data is the most important asset in the financial sector. On average, 71 percent of financial institutions generate competitive advantage over data analysis. In particular, in the card industry, the card transaction data is widely used in the development of merchant information, economic fluctuations, and information services by analyzing patterns of consumer behavior and preference trends of all customers. However, creation of new value through fusion of data is insufficient. This study introduces the analysis and forecasting of consumption trends of credit card companies which convergently analyzed the social data and the sales data of the company's own. BC Card developed an algorithm for linking card and social data with trend profiling, and developed a visualization system for analysis contents. In order to verify the performance, BC card analyzed the trends related to 'Six Pocket' and conducted th pilot marketing campaign. As a result, they increased marketing multiplier by 40~100%. This study has implications for creating a methodology and case for analyzing the convergence of structured and unstructured data analysis that have been done separately in the past. This will provide useful implications for future trends not only in card industry but also in other industries.

The random utility theory and the multinomial logit model (including a more recent variant--the mixed multinomial logit) derived from it have constituted a back bone for theoretical and empirical analyses of various travel demand features including mode choice. In their empirical applications, however, it is customary to specify random utilities which are linear in modal attributes such as time and cost, and in socio-economic variables. The linearity helps easy derivation of important information such as value of travel time savings by calculating marginal rate of substitution between time and cost. In this paper the author focuses on the very linearity of the random utilities. Taking into account the fact that the mode chooser is also labour supplier, commodity consumer as well as leisure-seeker, the author sets up a maximization model of the traveller, which encompasses various economic activities of the traveller. The author derive from the model the indifference curve defined on the space of modal attributes, time and cost and investigate under what conditions the random utility of the traveller becomes linear. It turns out that there exist the conditions under which the random utility is really linear in modal attributes, but the property does not hold when the traveller has a corner solution on the space of modal attributes, or when the primary utility function of the traveller is directly affected by labour provided and/or the travel time itself. As a corollary of the analysis, a random utility is suggested, approximated up to the second order of the variables involved for empirical studies of the field.

This study is aimed to analyze the concept of media consumer and legal principles for consumer movements protection. Based on the concept and legal principles, this research is to review the characteristics of the advertisement boycott campaign. Article 124 of the Constitution prescribes that the state should guarantee the consumer protection movements. According to the Article 4 of the Framework Act on Consumer, consumers have the fundamental right to obtain proper compensation for damages sustained due to use of goods and etc. according to prompt and fair procedure. The type of boycott can be classified into two pattern on the basis of boycott's target or object. They are primary boycott and. secondary boycott. Consumer's boycott independent of primary or secondary, are under the protection of the consumer's right. Media consumers use scarce resources to satisfy their wants and needs to acquire news information and advertising information. Their resources are time and money. Therefore, ads boycott campaign or media boycott campaign is the primary boycott. Consumer's right should be guaranteed to the maximum. The Constitution and consumer protection law should protect the practice of consumer's right, especially consumer's boycott campaign.

This study deals with the rent-seeking behavior that exist in cultural voucher from the viewpoint of culture and arts management. Art organizations open to consumers, producers and governments of the arts are dependent on the internal and external influence of an open system. Researcher has found rent-seeking in the course of introducing policies and legalization of the cultural voucher business which has been promoted in the direction of democratization of culture or cultural democracy. Cultural voucher business is a legal term. Although the government has increased the budget or tried to change the policies of the cultural voucher business, the implementation of the cultural voucher business has been opposed to the diversity of consumption and equity as the consumption of genre and the concentration of the capital region have increased. These results were structurally related to the process of legalization and rent-seeking behavior in bureaucracy. This study reaffirms that the efficient operation standard of the cultural voucher business is a balance between the choice of the beneficiary, the competition of the supplier, and access to the cultural voucher. And the theory of rent-seeking was applied as a criterion to analyze this balance. Thus, it is suggested that the criteria of evaluation and improvement to check the conservativeness of bureaucrats are needed to establish a legal system applied to the purpose of 'cultural democracy' and 'democratization of culture' ideology and to guarantee individual creativity and autonomy.

Purpose: The purpose of this study is to grasp the concept of ethical consumption that is inevitably one of the behaviors of consumption and to find factors affecting ethical consumption. The most special idea of this study is including motive in the research model. And motive will influence the factors affecting the intention to behave. Research design, data, and methodology: Considering variables affecting ethical consumption, we first adopted the T theory of Planned Behavior. There are three variables of attitude, subjective norm, and perceived behavior control in the model. In addition to variables used in the Planned Behavior Theory, ethical duty, self-identity, motive, neutralization, ambivalence are included in the study. Questionnaires are made for survey, and investigation was conducted from 1th March to 11th of March. Total 360 copies are used for analysis. SPSS version 23 was used for analysis. Results: Study results show that first, the variables of attitude, subjective norm, perceived behavioral control, ethical duty, self-identity are turned to be statistically significant factors affecting ethical consumption intention. In this study, we defined the ethical consumption as voluntary, self-sacrifice needed, and additional efforts required behavior, therefore motive thought to be needed at fist for individual consumer to form intention. For neutralization and ambivalence, neutralization does not affect ethical consumption directly or indirectly, but we found ambivalence has moderating effect while motive affecting attitude, perceived behavior control, self-identity and has moderating effect while attitude, subjective nom, perceived behavior control, self-identity affects intention. Ambivalence means individual consumer's thought or preoccupation toward ethical consumption, in other words, consumer may have fiendly or unfriendly, positive or negative impression to it. Overall, motive and ambivalence are important factors for ethical consumption. Motive plays some role from the start influencing main factors affecting ethical consumption. Ambivalence also functions by moderating variables. Thinking of ambivalence taking account of essence of ethical consumption, some consumers may have pretext or justification for not doing ethical consumption which may again annoy themselves. Conclusions: In conclusion, for intention to ethical consumption to be formed motive should be activated beforehand and ambivalence should be considered. Negative ambivalence toward ethical consumption should be removed and positive ambivalence should be developed.

Game is the cultural product, which gives users high authority in usage process with its high interactivity. This study is about the user innovation based on customer empowerment, and the possibilities to change the game itself applying high activity of the game. Especially, game modification, which users transform the original game, is an example that the interactivity and changeability of game are maximized. However, these elements were not considered when constructing frameworks to investigate the competition and strategy in game industry. Therefore, this study is based on the customer empowerments of the game modification. Moreover, this study proposes the newly reorganized strategic group map in game industry, which is based on game user innovation and user evaluation.

A generation of rules or patterns for detecting attacks from network is very difficult. Detection rules and patterns are usually generated by Expert's experiences that consume many man-power, management expense, time and so on. This paper proposes statistical methods that effectively detect intrusion and attacks without expert's experiences. The methods are to select useful measures in measures of network connection(session) and to detect attacks. We extracted the network session data of normal and each attack, and selected useful measures for detecting attacks using relative entropy. And we made probability patterns, and detected attacks using likelihood ratio testing. The detecting method controled detection rate and false positive rate using threshold. We evaluated the performance of the proposed method using KDD CUP 99 Data set. This paper shows the results that are to compare the proposed method and detection rules of decision tree algorithm. So we can know that the proposed methods are useful for detecting Intrusion and attacks.

Enterprise's executives who believe methodologies the theories prescribe consideration of consumer as rational and reasonable behavior. However, by recent investigation, consideration of consumer can be defined behavior that is occurred by sensibility. These consideration of consumer affect to a process that purchase a product, consumer's purchase decision process. Consumer make a purchasing decision with sensible criterion, respective of quality after all rather than various rational criterion like price, efficiency and usefulness. Brand image has sensible value to thought in the mind about a product and affect to purchase products. Hence building brand image through positive sensitivity is significant point in strengthening. Research from this point of view makes a content advance with improving product process along storytelling method which kind of affective, sensible communication way as a factor of strengthening brand image.

This study applies a discrete-continuous choice model to a national survey data set of automobile uses to investigate the potential impacts of a bonus-malus system for new cars in Korea. Not only the impacts on the discrete choice of automobile type and class but also those on the continuous decision making of car operation are analyzed. The characteristics of automobiles and individuals that determine car choice and operation are identified. The simulation based on the estimation result shows that an appropriately designed bonus-malus system can induce a reduction in energy consumption and $CO_2$ emission substantially without additional government expenditure.

In this paper we design and implement a sensor network management framework(SNMF) for ubiquitous sensor networks(USNs). The SNMF employs the policy-based management approach for the autonomous and energy-efficient management of USNs. Moreover, a new light-weight policy distribution protocol called TinyCOPS-PR is designed and USN PIB for low-level policy is also defined. This allows the high-level policies defined by an administrator to translate into the specific low-level policies. The low-level policies are executed on sensor nodes so it can fulfill the proper management actions. The sensor nodes that receive some policies from an administrator perform local management actions according to those policies. SNMF can therefore realize small energy consumption and bring long network lifetime. It can also manage USNs automatically with a minimum of human interference.
