This study is conducted to examine how purchase behaviors of consumers have affected by the promotion of coupons in internet shopping mall. This study was conducted with the purpose of identifying the differences In purchase behavior based on consumer's perception and experience of internet shopping mall coupons, and based on consumers' perception of cost and value of coupons, using a theoretic framework presented in previously conducted studies. The results of this study can be summarized as follows. First, based on the perception of coupons, there were significant differences in intent to use and intent to re-use at the time when coupons are offered, and at the time when coupons are offered, no significant differences were found between the level of interest and the importance of coupon at the time of visiting the shopping mall; however, significant differences were found in the overall purchase behavior based on perception of coupons. Second, when overall differences In purchase behavior based on experience in coupon use was observed, having experience in using coupons showed a higher average than did having no experience in using coupons, showing a significant difference. It was found that compared to those without experience in using coupons, those with experience with coupons had higher intent to use at the time when coupon is offered, intent to re-use at the time when coupon is offered, and higher level of purchase behavior In the importance of coupons at the time of visiting the shopping mall. Third, when relationship between purchase behaviors, cost of coupon, and perception of convenience was observed, a clear static relationship was found. This suggests that as the cost and perception of convenience of coupon increases, purchase behavior also increases. Such result suggests that there is a difference in purchase behavior based on experience in coupon use. When relationship of purchase behavior by variables of cost of coupon and perception of convenience is observed, it has a positive relationship with the perception that the use of coupon includes saving money, financial help, enjoyment of use, habitual use, has a short effective date, and has a negative relationship with the perception that it saves little money and is a waste of time. Therefore, it can be seen that purchase behavior has the highest relationship with enjoyment of coupon use and habitual coupon use. Such results suggest that purchase behavior will be significantly influenced based on cost of coupon and perception of convenience.

This study aims at investigating the effect of heat treatment conditions on the dry sliding wear behavior of thermally sprayed Ni-based self-flux alloy coatings. Ni-based self-flux alloy powders were sprayed onto a carbon steel substrate and then heat-treated at 700, 800, 900 and $1000^{\circ}C$ for 30 minutes in a vacuum furnace. Dry sliding wear tests were performed using sliding speed of 0.4 m/s and applied load of 6 N. AISI 52100 ball(diameter 8 mm) was used as counterparts. Microstructure and wear behavior of both as-sprayed and heat-treated Ni-based self-flux alloy coatings were studied using a scanning electron microscope(SEM), energy dispersive X-ray spectroscopy(EDX), electron probe micro-analysis(EPMA) and X-ray diffraction(XRD). It was revealed that microstructure and wear behavior of thermally sprayed Ni-based self-flux alloy coatings were much influenced by heat treatment conditions.

This study was a descriptive research to investigate the health promotion behavior and health status based on Korean adult's constitution. The subjects for the study were 96 adults who were the residents either in Seoul or Taegu city. The instruments used for this study included a survey of general characteristics, health promotion behavior and health status. The data were analyzed using t-test, ANOVA, Pearson correlation coefficient and Scheffe method as post hoc test. The results of this study were summarized as follows : 1) There was no significant difference on the health promotion behavior and health status by constitutions. But, in the relationship between five factors of the health promotion behavior and constitution, there was significant difference on health responsibility by constitutions(F=3.31. P=.041). According to the scheffe test, Taeumin group performed better behavior for the health promotion than soyangin group. 2) Health promotion behavior was significantly related to health status (r=-.24, P=.025), suggesting that the person with high health promotion behavior get higher health status scores. 3) In the relationship between general characteristics variables and health promotion behavior, there were significant differences in education(F=3.12, P=.031), economic status(F=4.09, P=.021), religion (F=3.12, P=.031). The level of health promotion behavior of high educated persons and high economic status persons was high. The persons who believe in Catholicism performed better behavior for the health promotion than the persons who don't get religion. Based on these results, to determining and fully understanding client's constitution are the foundations of Eum-Yang and personal character. Therefore, we have to consider the constitution when we provide nursing care. When we consider the differences of health promotion behavior according to constitution, we can provide the client with the kind of nursing care and health education to satisfy their demands.

In line with network technology development and smart device penetration, the social network service (SNS) has expanded its influence. The SNS which is a service based on communication and sharing among people, has grown based on users' voluntary engagement and participation and its influence has appeared beyond the cyberspace into the overall areas of domestic and foreign culture and society. In particular, SNS-based real-time communication during diverse disasters, can help prevent further damage. By sharing information on social donation activities and environmental campaigns, people have used SNS as a tool to change the society in a more positive way. Such series of activities functioning as a power to change the society have been made much faster and wider through the help of a new media called SNS. To better understand such trends, we are required to study about the SNS and its user relationships first. In this context, this study sought to identify the effects of people's desire to build friendships through SNS on the voluntary and society-friendly activities of people. This study considers online pro-social behavior and proposes online citizenship behavior. Citizenship behavior has been examined in organization context. That is, organizational citizenship behavior explains an employee's pro-social behavior in an organization context. Organizational citizenship behavior is characterized by the individual's helping others and promoting the functioning of the organization. By applying organizational citizenship behavior to an online context, we propose online citizenship behavior, an individual's pro-social behavior in an online context. An individual's pro-social behavior, i.e., online citizenship behavior, could be considered as a way for the better management of online community and society. It also needs to examine the development of online citizenship behavior. This study examined online citizenship behavior from the friendship desire. Because online society or community is characterized by online relationships between members, the friendship between members would lead to pro-social behavior, i.e., helping others and promoting the functioning of the online society, in such online context. This study further examines the antecedents of friendship desire in terms of SNS interactivity with its four factors. The findings based on the survey from real SNS users explain that the three factors of SNS interactivity (connectivity, enjoyment, and synchronicity) increases online friendship desire which then increases online citizenship behavior significantly. This study contributes to the literature by examining the key role of online friendship desire in leading to online citizenship behavior and identifying its antecedents in terms of SNS characteristics. The findings in this study also provide guidance on how to manage online society and how to promote the effective functioning of SNS.

The main objective of this research is to investigate whether the RFM (recency-frequency-monetary value) information of a customer's redemption behavior of loyalty points can improve the prediction of future value of the customer. The conventional measurement of customer value has been primarily based on purchase transactions behavior although a customer's future behavior can be also influenced by other interactions between the customer and the firm such as redemption of rewards in a loyalty program. We theorize why a customer's redemption behavior can influence her future purchases and thereby the customer's total value based on operant learning theory, goal gradient hypothesis, and lock-in effect. Using a dataset from a major book store in Korea spanning three years between 2008 and 2010, we analyze both purchase transactions and redemption records of over 10,000 customers. The results show that the redemption-based RFM information does improve the prediction accuracy of the customer's future purchases. Based on this result, we also propose an improved estimate of customer lifetime value (CLV) by combining purchase transactions and loyalty points redemption data. Managerial implications will be also discussed for firms managing loyalty programs to maximize the total value customers.

The purpose of this paper is to compare seafarers' behavior according to traffic conditions of a road and an onshore locations. Behaviors are classified into three categories: Skill-, Rule- and knowledge-based mode. Experimental data were collected using the questionnaires for navigators, working in a merchant ship. To compare the behaviors, we used the four analysis method; the degree of frequency, reliability test, correlation and linear regression. As a result of the study, it was found that Skill-based behavior shows more higher in the road traffic than the maritime traffic, and rule-based behavior shows more higher in the maritime traffic than the road traffic. Also, the behavior in the navigation situation showed statistical significance. Especially, in the case of Rule-based behavior, a high correlation between road and maritime was found. This study can be expected to apply to complementary system utilization between error management system of onshore and maritime traffic.

The 5G Core Network (5GC) is an essential part of the mobile communication network, but its security protection strategy based on the boundary construction is difficult to ensure the security inside the network. For example, the Network Function (NF) mutual authentication mechanism that relies on the transport layer security mechanism and OAuth2.0's Client Credentials cannot identify the hijacked NF. To address this problem, this paper proposes a trust model for 5GC based on NF interaction behavior to identify malicious NFs and improve the inherent security of 5GC. First, based on the interaction behavior and context awareness of NF, the trust between NFs is quantified through the frequency ratio of interaction behavior and the success rate of interaction behavior. Second, introduce trust transmit to make NF comprehensively refer to the trust evaluation results of other NFs. Last, classify the possible malicious behavior of NF and define the corresponding punishment mechanism. The experimental results show that the trust value of NFs converges to stable values, and the proposed trust model can effectively evaluate the trustworthiness of NFs and quickly and accurately identify different types of malicious NFs.

This study investigated creative behavior, one of organizational effectiveness, needed to survive in the rapidly changing circumstances. So, transformational leadership was setting as independent variables consist of ideal influence, intellectual stimulus and individual consideration, and affect-based trust and cognition-based trust was setting as mediating variables. For this study, 211 of the respondent, who are attending various companies, answered this questionnaire. This study shows that ideal influence, intellectual consideration and individual consideration of transformational leadership have positive(+) direct impact to creative behavior, and in affect-based trust, transformational leadership has impact on the creative behavior, as fully positive(+) mediating effects. In cognition-based trust, trust has impact partly as mediating effects. Namely, transformational leadership is based on affect-based trust will be heightened after all creative behavior. Impact of control variables is more larger in man, under 30 age, public workers.

Objectives: This study was to develop a measurement scale that explains aggressive regulation behavior of middle school student, based on Ajzen's Theory of Planned Behavior (TPB) and verify its validity and reliability. Methods: The basic items were modified by selecting 41 items of middle school student aggressive behavior measurement scale. Through the content validity test, 63 first preliminary question items and 42 second preliminary question items were developed. The participants were 286 middle school students. The collected data were analyzed using content validity, correlation coefficient, exploratory factor analysis, confirmatory factor analysis, reliability and Cronbach α. Results: In this study, it was proved that the most important variable showing aggressive regulation behavior was aggressive regulation intention. This study was composed of 4 factors for direct measurement(attitude toward the behavior, subjective norm, perceived behavioral control, behavior intention) and 5 factors for indirect measurement(behavioral beliefs, outcome evaluation, normative beliefs, motivation to comply, control beliefs). The total variance was 65.4% and 67.6%, respectively, and the reliability was .90, .82. Finally, 42 questions were developed. Conclusion: We found the questionnaire used in this study was valid and reliable as a measure scale to explain the aggressive regulation behavior of middle school student based on TPB. Therefore, it is concluded that the aggressive regulation behavior scale could be a useful scale for the measurement of the aggressive regulation behavior of middle school student.
