This study aims to investigate the effect that local government's information release range on Covid-19 patients' contact trace on consumer sentiment in the region. One hundred twenty-eight residents of Gangnam-gu and Seocho-gu participated in the study. The results showed that when ambiguity of information increased perceived anxiety on Covid-19 patients' contact trace, which in turn led lower intention to visit the commercial district near the Covid-19 patients' contact trace. Based on the findings, several suggestions was proposed for future research, including longitudinal studies covering even the "long-term" changes in consumer sentiment, the effect of implicit anxiety, and the behavioral difference between residence and non-residence.

Although concerns about the opinion shopping have been continuously raised in the audit market, there has been little research on empirical evidence on the existence of audit opinions. For this reason, this study empirically confirmed whether the opinion shopping exists. At first, we measured thresholds of audit opinion issuing of two groups(changed or not-changed auditors). After that, the difference analysis was conducted to verify whether the thresholds of the audit opinion issuing was significant difference between two groups. As a result of the study, there was no significant difference in the thresholds of audit opinion issuing between two groups. This result can be interpreted that the audit opinion shopping is not a general phenomenon in the external audit market. The contribution of this study is to empirically confirmed that audit opinion shopping does not exist in the external audit market.

SaaS at a cloud computing is a framework to provide a software as a service. Depending on the difference of the tenant and the use, if the service provider re-establish a service, they are required resources In terms of costs and managerial. So we propose a technique for analysis of software structure using the process algebra to reuse existing software. A process algebra analyze the structure of the software, express in different languages and verify that it can be reused. CCS in a process algebra is useful to convert the business process or XML, by using this, we structure a process as process view and propose meta storage for comparison and management a structured document.

Global commerce is apparently here to bind Korean firms as well as Koreans. The advertising, buying and selling of goods and services recognizes no borders. As a result, enforcing territorially based trademark rights has become ever more challenging. Remote trademark owners who peacefully coexisted in a time before the internet and increasing globalism are now bumping heads. The internet also has made it easier for unscrupulous operators to deceive consumers and divert customers from established businesses by misappropriating trademarks on web-sites and in domain names. U.S. federal courts have been willing to help American businesses halt trademark infringements that reaches outside the United States. This is particularly true for e-business, via the internet, and the trend toward enforcement seems to be in favor of the trademark owner. This article discusses this trend as well as the extraterritorial enforcement of trademark rights by U.S. courts under the Lanham Act. It also offers suggestions for protecting valuable trademark rights worldwide. This paper will contribute to global Korean firms and Koreans who carefully read arguments in this valuable literature.

Korean service industry has been rapidly growing so far and economic trends in korea is shifting to service economy. However Information Communication Technology (ICT) investment and use in service sector are still relatively low in comparison with US. Keeping the current state of the service industry in mind, this paper is to review the potential productivity growth of service industry empirically by analyzing the effect of ICT on total factor productivity after investing the ICT using outlook of Korean service industry. The results show that service sectors, with more using ICT, show high productivity growth and stable TFP change during the financial period. Sectors with lower using ICT are more sensitive to changes in the business environment when compare to sectors with highly using ICT. Concerning the period of 1997-1999, the TFP growth of most of sectors slowed down and turned to recovery immediately afterwards, 2000-2002.

Given social problems of technology addiction such as games and mobile messenger services (MMSs), it have become important to understand theoretical mechanisms to generate technology addiction. In this vein, this study examined key antecedents of technology addiction in the MMS environment. We posit technology habit and user satisfaction as key predictors of technology addiction. In addition, the impacts of social interaction and flow on use's technology addition formation were investigated The research framework was tested by using survey data collected from 278 Kakaotalk users who have used more than 6 months. The analysis results found that both technology habit and user satisfaction play an important role in generating technology addiction in the MMS context. The findings of this study indicate that social interaction and flow significantly affects technology habit and user satisfaction. The analysis results help government and MMS providers establish policies or strategies to induce healthy MMS use.

This paper analyses whether change in corporate dividend policy affects the new issue announcement effects. By conducting an event study using 683 new equity announcements data from year 2000 to year 2009, we find firms paying more dividends experience relatively negative announcement effects of seasoned equity offerings comparing with firms paying less dividend. The cross sectional regression analysis results confirm our findings. These results indicate that corporate dividend policy change may interact with forthcoming new equity announcement decision, which may result in a negative signal to the capital markets.

Advances of digital device technology such as digital cameras, smart phones and tablets, provide convenience way for people to take pictures during his/her life. Photo data is being spread rapidly throughout the social network, causing the excessive amount of data available on the internet. Photo retrieval is categorized into three types, which are: keyword-based search, example-based search, visualize query-based search. The commonly used multimedia search methods which are implemented on Smart TV are adapting the previous methods that were optimized for PC environment. That causes some features of the method becoming irrelevant to be implemented on Smart TV. This paper proposes a novel Visual Query-based Photo Retrieval Method in Smart TV Environment using a motion sensing input device known as Kinect Sensor. We detected hand gestures using kinect sensor and used the information to mimic the control function of a mouse. The average precision and recall of the proposed system are 81% and 80%, respectively, with threshold value was set to 0.7.

In our country, the real estate information system is operated by public and private institutions to trade real estate effectively from the 1990s. The purposes of this study is as follows: First, this study is aimed to examine how the system quality, information quality and service quality of the real estate IS is related with the system use and user satisfaction. In addition real estate practitioners and real estate non-practitioners is to investigated how different. Regression and t-test analysis was carried out as statistical analysis and survey data was used. The result is as follows: First, in the real estate non-practitioners group, system quality has significant negative impact on the user satisfaction. Second, information quality has significant impact on the user satisfaction in the real estate non- practitioners group. One limitation of this study is that it is limited to the real estate agents among various groups that use the IS. Thus, in the future studies, the target group should be extended to other various groups and more specific IS among various ones should be studied in a more practical way.
