This study is a smart tourism research based on face recognition applied system that manages individual information of foreign tourists to smartphone. It is a way to authenticate by using face recognition, which is biometric information, as a technology applied to identification inquiry, immigration control, etc. and it is designed so that tourism companies can provide customized service to customers by applying algorism to smartphone. The smart tourism system based on face recognition is a system that prepares the reception service by sending the information to smartphone of tourist service company guide in real time after taking faces of foreign tourists who enter Korea for the first time with glasses attached to the camera. The smart tourism based on face recognition is personal information recognition technology, speech recognition technology, sensing technology, artificial intelligence personal information recognition technology, etc. Especially, artificial intelligence personal information recognition technology is a system that enables the tourism service company to implement the self-promotion function to commemorate the visit of foreign tourists and that enables tourists to participate in events and experience them directly. Since the application of smart tourism based on face recognition can utilize unique facial data and image features, it can be beneficially utilized for service companies that require accurate user authentication and service companies that prioritize security. However, in terms of sharing information by government organizations and private companies, preemptive measures such as the introduction of security systems should be taken.

Cyber defamation is the act of damaging the reputation of the other person on the Internet, and the act of attacking by the commenting the article through a word or blog. The reason why punishment is stronger than general contempt is that the nature of crime about defamation is worse than contempt. Also, punishment intensity is higher than defamation because the nature of cyber information spreads widely. Honor is not only a question of self-esteem or identity, but also a function that economically reduces the cost of seeking information or socially trustworthy. Through these two functions, it has been developed as a legal system to protect the honor as well as asking the legal sanction for defamation. However, although honor is used in various meanings in everyday life, the honor of legal level is understood in a more limited sense. It is because the law cannot actively lead and protect all honor feelings for one's feelings or mood occurred by hurt. However, if the social evaluation of a group or individual is undermined through a certain distortion of the truth, the law will actively intervene. However, due to the ambiguity of the legal sanctions standards and the identification of the parties involved in the defamation of cyberspace, it was difficult to solve the problems related to defamation in fact. Therefore, this paper will try to find out the problems of civil legal remedy due to the cyber defamation, and seek a solution for civil legal remedy.

This discovery-oriented study explored 31 social workers' perceptions of discrepancies between explicit and implicit rules in their work places that are supposed to affect the quality of social work services, and identified eight categories of dilemmas: (a) confused accountability or purpose, (b) ambiguous principle, (c) improper authority, (d) confused role of social workers, (e) conflict between ideal and reality, (f) confused work ethics, (g) confused boundary of workers' rights, and (h) binds. These eight categories revealed the real philosophy and purposes of social work agencies, work ethics and values prevalent among social work agencies, agencies' orientation toward clients, and the conditions of social support from the society in large. Instead of searching for discrete variables as separately responsible for inefficient social work services, this approach probed malfunctioning implicit rules in a holistic context to see if inefficient or ineffective provision of social work services is a logical response to a much larger and deeper nexus. Insight into discrepant rules does not solely ensure the improvement of social work practice in the field, particularly if their identification is simply used as another opportunity to blame and avoid self-responsibility. However, such discrepancies between implicit and explicit rules are real enough to the staff workers and agency administrators that they may want to begin the dialogue of contradictory rules as a way of sanctioning discussion of previously forbidden topics. This study provided the ground-work for the dialogue.

SNS is developing rapidly along with diffusion of smartphone. However as useage of SNS became excessive, SNS addiction became a social problem. Meanwhile the problem that users leavning SNS because of negative perceptions about SNS became issue. As both SNS addiction and continuance are important when using SNS, this study examines factors affecting Facebook addiction and continuance. We derive three personal traits, which is autonomy, competence, relatedness as variables that affect Facebook addiction and continuance to use Facebook. The authors' structural equation model using data, collected from 204 Facebook user, showed that autonomy and competence significantly affected Facebook addiction. Also, autonomy, competence and relatedness significantly affect Facebook continuance.

The objective of this study was to investigate the developmental level of Rural Women Leaders Federation(RWLF) which is one of the major rural women`s association in Korea. The writers designed organization measurement tool based on the reviews on the related studies and gather data from 191 memberships of RWLF through the mail questionnaire and interviews. The major findings were as follows; First, the findings shows us this organization as transition period from identification stage to expanded growth stage in developmental stage of rural women's organizations. Second, this organization focus on share of members decision making and leadership style rather than organization`s vision, strategy or organization level. In other words, this organization focus on human relations aspect rather than internal aspect of organization system. Third, this organization has high level of social evaluation of the organization, even if it has low level of personal compensation or individua's social performance. In conclusion, as long-term view-point, it is needed to help them to promote their self-control of survival ability to improve organization's vision, strategy, differentiation for achieving organizational goals. And it also needed to prepare educational programs to increase Rural Women's leadership capability understanding of organizational characteristics and its operation abilities.

The purpose of this study were to examine the effect of consumer-brand relationship of fashion luxury product on brand loyalty and the mediating effect of consumer satisfaction. The questionnaire developed through the literature search and a survey was conducted both in on-line and off-line questionnaire simultaneously. Finally 227 data from women who had a buying experience of fashion luxury products were analyzed using frequency, factor analysis, ANOVA, t-test, regression analysis by SPSS for WIN program. The results were as follows. First, the consumers' brand identification was composed of three factors; self-connection, interdependence, attachment. Second, the consumer-brand relationship significantly influenced on the brand loyalty. Third, the consumer-brand relationship significantly influenced on the consumer satisfaction. Fourth, the consumer satisfaction significantly influenced on the brand loyalty. Fifth, the consumer-brand relationship had both direct and indirect effects on brand loyalty mediated by consumer satisfaction. The results indicated that causal relationship was existed among these three variables.

In this paper, a sliding mode and proportional plus integral (SM-PI) control combined with self-sustained phase shift modulation (SSPSM) for LLC resonant converters is presented. The proposed control scheme improves the transient response while preserving good steady-state performance. An averaged large signal model of an LLC converter with the ZVS modulation technique is developed for the SM control design. The sliding surface is obtained based on the input-output linearization concept. A system identification method is adopted to obtain the transform function of the LLC resonant converter, which is used to design the PI control. In order to reduce the inherent chattering problem in the steady state, the combined SM-PI control strategy is derived with fuzzy control, where the SM control is responsive during the transient state while the PI control prevails in the steady state. The combination of SSPSM and the SM-PI control provides ZVS operation, robustness and a fast transient response against step load variations. Simulation and experimental results validate the theoretical analysis and the attractive features of the proposed scheme.

Conventional methods for pathogen detection and identification are labor-intensive and take several days to complete. Recently developed biosensors have shown potential for the rapid detection of foodborne pathogens. In this study, an impedimetric biosensor was developed for rapid detection of Salmonella typhimurium. To develop the biosensor, an interdigitated microelectrode (IME) was fabricated by using semiconductor fabrication process. Anti-Salmonella antibodies were immobilized based on either avidin-biotin binding or self assembled monolayer (SAM) on the surface of the IME to form an active sensing layer. To evaluate effect of antibody immobilization methods on sensitivity of the sensor, detection limit of the biosensor was analyzed with Salmonella samples innoculated in phosphate buffered saline (PBS) or food extract. The impedimetric biosensor based on SAM immobilization method produced better detection limit. The biosensor could detect 107 CFU/mL of Salmonella in pork meat extract. This method may provide a simple, rapid, and sensitive method to detect foodborne pathogens.

In this paper, we propose Neuro Fuzzy Polynomial Networks(NFPN) based on Polynomial Neural Network(PNN) and Neuro-Fuzzy(NF) for model identification of complex and nonlinear systems. The proposed NFPN is generated from the mutually combined structure of both NF and PNN. The one and the other are considered as the premise part and consequence part of NFPN structure respectively. As the premise part of NFPN, NF uses both the simplified fuzzy inference as fuzzy inference method and error back-propagation algorithm as learning rule. The parameters such as parameters of membership functions, learning rates and momentum coefficients are adjusted using genetic algorithms. As the consequence part of NFPN, PNN is based on Group Method of Data Handling(GMDH) method and its structure is similar to Neural Networks. But the structure of PNN is not fixed like in conventional Neural Networks and self-organizing networks that can be generated. NFPN is available effectively for multi-input variables and high-order polynomial according to the combination of NF with PNN. Accordingly it is possible to consider the nonlinearity characteristics of process and to get better output performance with superb predictive ability. In order to evaluate the performance of proposed models, we use the nonlinear function. The results show that the proposed FPNN can produce the model with higher accuracy and more robustness than any other method presented previously.
