Smartphone and its applications (i.e. apps) are increasingly penetrating consumer markets. According to a recent report from Korea Communications Commission, nearly 50% of mobile subscribers in South Korea are smartphone users that accounts for over 25 million people. In particular, the importance of smartphone has risen as a geospatially-aware device that provides various location-based services (LBS) equipped with GPS capability. The popular LBS include map and navigation, traffic and transportation updates, shopping and coupon services, and location-sensitive social network services. Overall, the emerging location-based smartphone apps (LBA) offer significant value by providing greater connectivity, personalization, and information and entertainment in a location-specific context. Conversely, the rapid growth of LBA and their benefits have been accompanied by concerns over the collection and dissemination of individual users' personal information through ongoing tracking of their location, identity, preferences, and social behaviors. The majority of LBA users tend to agree and consent to the LBA provider's terms and privacy policy on use of location data to get the immediate services. This tendency further increases the potential risks of unprotected exposure of personal information and serious invasion and breaches of individual privacy. To address the complex issues surrounding LBA particularly from the user's behavioral perspective, this study applied the privacy calculus model (PCM) to explore the factors that influence the adoption of LBA. According to PCM, consumers are engaged in a dynamic adjustment process in which privacy risks are weighted against benefits of information disclosure. Consistent with the principal notion of PCM, we investigated how individual users make a risk-benefit assessment under which personalized service and locatability act as benefit-side factors and information privacy risks act as a risk-side factor accompanying LBA adoption. In addition, we consider the moderating role of trust on the service providers in the prohibiting effects of privacy risks on user intention to adopt LBA. Further we include perceived ease of use and usefulness as additional constructs to examine whether the technology acceptance model (TAM) can be applied in the context of LBA adoption. The research model with ten (10) hypotheses was tested using data gathered from 98 respondents through a quasi-experimental survey method. During the survey, each participant was asked to navigate the website where the experimental simulation of a LBA allows the participant to purchase time-and-location sensitive discounted tickets for nearby stores. Structural equations modeling using partial least square validated the instrument and the proposed model. The results showed that six (6) out of ten (10) hypotheses were supported. On the subject of the core PCM, H2 (locatability ${\rightarrow}$ intention to use LBA) and H3 (privacy risks ${\rightarrow}$ intention to use LBA) were supported, while H1 (personalization ${\rightarrow}$ intention to use LBA) was not supported. Further, we could not any interaction effects (personalization X privacy risks, H4 & locatability X privacy risks, H5) on the intention to use LBA. In terms of privacy risks and trust, as mentioned above we found the significant negative influence from privacy risks on intention to use (H3), but positive influence from trust, which supported H6 (trust ${\rightarrow}$ intention to use LBA). The moderating effect of trust on the negative relationship between privacy risks and intention to use LBA was tested and confirmed by supporting H7 (privacy risks X trust ${\rightarrow}$ intention to use LBA). The two hypotheses regarding to the TAM, including H8 (perceived ease of use ${\rightarrow}$ perceived usefulness) and H9 (perceived ease of use ${\rightarrow}$ intention to use LBA) were supported; however, H10 (perceived effectiveness ${\rightarrow}$ intention to use LBA) was not supported. Results of this study offer the following key findings and implications. First the application of PCM was found to be a good analysis framework in the context of LBA adoption. Many of the hypotheses in the model were confirmed and the high value of $R^2$ (i.,e., 51%) indicated a good fit of the model. In particular, locatability and privacy risks are found to be the appropriate PCM-based antecedent variables. Second, the existence of moderating effect of trust on service provider suggests that the same marginal change in the level of privacy risks may differentially influence the intention to use LBA. That is, while the privacy risks increasingly become important social issues and will negatively influence the intention to use LBA, it is critical for LBA providers to build consumer trust and confidence to successfully mitigate this negative impact. Lastly, we could not find sufficient evidence that the intention to use LBA is influenced by perceived usefulness, which has been very well supported in most previous TAM research. This may suggest that more future research should examine the validity of applying TAM and further extend or modify it in the context of LBA or other similar smartphone apps.

Purpose This study aims to investigate the factors that influence decision making in relation to providing personal information on the internet with respect to the integration of the privacy calculus theory and protection motivation theory based on the dual-calculus model proposed by Li(2012). Design/methodology/approach The privacy calculus theory and protection motivation theory have been applied to explain privacy behavior to a certain degree but few studies have been conducted to explain privacy behavior based on the integration of these two theories. Although Li(2012) proposed the dual-calculus model, he only proposed its framework and did not carry out an empirical study. Therefore, this study proposes a research model that integrates these two theories and examines the relationship between the two theories through an empirical study. Findings According to the results of empirical analysis, it was found that all relations have statistically significant explanatory power except the relation between coping appraisal and privacy risk in the risk calculus process. Thus, the results verify that external threat played a decisive role in increasing the risk level of a consumer's privacy. It can be discussed the ways to enhance the privacy behavior of consumer on the internet through these findings.

Recently, rapid innovation of Smartphone is changing the paradigm of our daily life. Smartphone users, opinion experts more than 99 percent of the economically active population is using, it has reached the saturation past the early stages of formation. Smartphone is equipped with a general purpose OS possible the implementation of high performance environment similar level as a personal computer. Also, it is a mobile communication terminal scalable which can be removed or installed various applications. Such extensibility, it is possible to use different applications through the Apps store. In addition, it is also possible various services which are location based service. However, these services also benefit many but it also has a disadvantage of invasion of privacy and disclosure of personal information. In this research, we aim to analyze factors influencing on perceived value and risk in location based service of Smartphone. In addition, we aim to analyze the causal relationship with perceived value and risk in satisfaction and recommendation intention. This study suggests practical and theoretical implications based on the results.

The purpose of this study was to examine the effect of donation expenditure details and the shift in awareness as a result of disclosure of donation expenditure details in order to promote constant donation by nonprofit organizations in the course of marketing activities. The first experiment was configured through $2{\times}2$ intergroup element design based on 2(feedback on donation expenditure details: available vs. unavailable) ${\times}$ 2(donation awareness: expenditure vs. exchange), and furthermore, MANOVA was performed. The results showed that the satisfaction with donation was higher when the donation expenditure details were disclosed(M=5.125, SD=0.437) and that the relation maintenance intention was higher(p<0.01) when the donation expenditure details were disclosed M=5.328, SD=0.459). In addition, the main effect was validated by using the bootstrapping method. The results of overall model validation showed that satisfaction & trust(=0.843, p<0.01) and satisfaction(=0.267, p<0.01) and trust(=0.691, p<0.01) had a positive(+) relationship. Based on aforesaid results, donors are expected to have greater trust if nonprofit organizations make effort to ensure transparent and detailed disclosure of information on expenditure of donations made by donors. Succeeding studies would need to investigate the effect that might vary depending on the type of feedback methods, etc.

We analyze the information asymmetry in the capital market by examining the long-term performance by the insider's trading behavior in the companies that made investment announcements for the construction of the new office building. The results are summarized as follows. On average, the long-term abnormal returns on share prices of sample firms represent a significant positive value. The regression analysis confirmed that there is a statistically significant positive correlation between the factor of the change in equity of large shareholders and the long-term performance. On the other hand, negative correlation was observed between change in equity of small individual investors and long-term performance. These results mean that an insider can determine the authenticity of a manager's private intention. In other words, it supports that the insider is in a position of information superiority. In addition, it is expected to provide practical usefulness to investors in that the change in equity can be used as a predictor of long-term performance.

As the disclosure of privacy information has grown steadily, concerns about mobile services based on the personal information also increased. We aspired to reveal factors influencing the use of Location-Based services(LBS) App and analyse how the perceived risk affected between these factors and the use of LBS App. Results showed that usefulness and social influence influenced on the use of LBS App. We also found that the group who highly recognized the perceived risk was highly affected by usefulness and the group who lowly recognized the perceived risk was highly affected by social influence. Findings show that the company's strategy should be different depending on the level of consumers' perceived risk.

This study examined the factors that influence the smartphone user's decision to accept the personalized mobile advertisement. As a theoretical basis, we applied the privacy calculus model (PCM) that illustrates how consumers are engaged in a dynamic adjustment process in which privacy risks are weighted against benefits of information disclosure. In particular, we investigated how smartphone users make a risk-benefit assessment under which personalized service as benefit-side factor and information privacy risks as a risk-side factor accompanying their acceptance of advertisements. Further, we extend the current PCM by considering advertisement fatigue as a new factor that may influence the user's acceptance. The research model with five (5) hypotheses was tested using data gathered from 215 respondents through a quasi-experimental survey method. During the survey, each participant was asked to navigate the website where the experimental simulation of a mobile advertisement service was provided. The results showed that three (3) out of five (5) hypotheses were supported. First, we found that the intention to accept advertisements is positively and significantly influenced by the perceived value of personalization. Second, perceived advertisement fatigue was also found to be a strong predictor of the intention to accept advertisements. However, we did not find any evidence of direct influence of privacy risks. Finally, we found that the significant moderating effect between the perceived value of personalization and advertisement fatigue. This suggests that the firms should provide effective tailored advertisement that can increase the perceived value of personalization to mitigate the negative impacts of advertisement fatigue.

Objective: The purpose of this study is to find out the perception on childe abuse of pre-service childcare teachers who will become the closest witnesses to child abuse, and also whether they have the proper knowledge and attitude to report abuse. Methods: Surveys were conducted at five universities in Seoul and Kyonggi-province. We investigated students from child development major, and additionally students from other majors as a comparative group. Results: The results of this study are as follows: First, pre-service childcare teachers' level of abuse severity was significantly higher than other major students. They were more aware of child abuse reporting system and reporting obligations than other major students. Second, pre-service teachers had higher intention of reporting then other major students. However, both groups barely know about child protection institution, and have negative perception on the effect of reporting. Conclusion/Implications: In conclusion, this study suggests that pre-service teachers are more aware of child abuse and willing to report than other major students, however it is necessary to increase the reliability of report effectiveness. Also, it provide implications for future policy-making related to child abuse by suggesting that information transmission and promotion through mass media is necessary and efforts should be made to reduce the risk of disclosure of the identity of the complainant in reporting abuse.

The duty of utmost good faith is found in sections 17-20 of MIA 1906. Critics of the current legal regime on the pre-contractual duty from the viewpoint of the assured, have been concentrated on two points in particular. First, the scope of the duty is so wide that it imposes too high burden on the assured. The second criticism is directed at the remedy, prescribed by the MIA 1906, s.17, against breach of the duty. This article intends to analyse the legal implications of proposals in CP 2007 for reforming pre-contractual duty of utmost good faith of business assured in English insurance contracts law and the problems of proposals. The Law Commissions are proposing four fundamental changes to meet the long-standing criticism and the results of analysis are as following. First, the Law Commissions are proposing a change in the test of constructive knowledge in relation to the duty of disclosure so that a business assured will be obliged to disclose facts which he knows or a reasonable ought to know in the circumstances. Secondly, deviating from the current legal position, the Law Commissions are proposing that if a business assured has made a misrepresentation, but the assured honestly and reasonably believe what it said to be true, the insurer should not have any remedy due to the misrepresentation. The proposal is designed to protect the reasonable expectations of business assured at the pre-contractual stage. Thirdly, the Law Commissions are proposing to change the test for materiality by replacing the "prudent insurer" test by a "reasonable assured" test. The proposed test would focus on the question of what a reasonable assured in the circumstances would think what is relevant to the judgment of the insurer. Finally, the Law Commissions are proposing flexible remedies in case of the breach of the duty. The Law Commissions are proposing no remedy when an assured is acting honestly and reasonably, while avoidance in case of dishonesty. On the other hand, The Law Commissions seem to have an intention to introduce a compensatory remedy in case of negligent breach of the duty.
