This paper aims to study the influence of environmental attitudes on the choice of non-professional investors. It highlights the role of environmental performance assurance on investment judgments. This choice is due to the motivation and importance that investors place on the disclosure of environmental information. The main purpose of the research is focused on the empirical approach justified by the use of a questionnaire addressed to 200 non-professional investors. The results show that attitudes towards the environment do not correlate with the importance that gives this category of investors to the environmental information.. Subsequently, the results prove that the disclosure of an environmental assurance report has a positive impact on investment judgments independently of their appreciation of the environmental information concerning that of financial order.

In the field of education in Korea, University Information Disclosure System was conducted forcibly in December 2008 by Ministry of Education, Science and Technology. As a result, information quality provided to the user has been improved dramatically. Based on the preceding studies of information success model, the purpose of this study was to prove empirically three facts on the organization's performance, user's attitude, and gaps between two factors by improvement in the quality of information. To accomplish the purpose, literature review and statistical analysis were done using the university evaluation data published by JoongAng Daily from 2007 to 2011. The results of this study showed that the information quality had positive effect on organization's performance, user's attitude like a reputation, and the gaps between two factors. The results of this study had a great expectation for the role of offering useful insight and information in the field of information system and education.

The purpose of this paper is to analyze the stock market performances CAR of reorganized firms and study the disclosure effect of completion of reorganization to examine whether there exists significant economic merit for the institutionalized continuation of unprofitable firms. The main results of this paper can be summarized as follows. First, the average stock market performances for +12 months after the completion of reorganization compared to those for -6 months before the proposal of reorganization show consistently negative returns. Second, to see whether there exist significant differences between the stock market performances of reorganized firms and those of normal firms with similar characteristics, CAR's measured from -6 months before the proposal of reorganization to +12 months after the completion of reorganization are statistically tested, which results in significantly negative values starting +5 months after the completion of reorganization. Finally, to see the disclosure effect of the news of completion of reorganization, daily CAR's are measured and tested, which shows positive values only for -20 days and -19 days before the disclosure, and shows negative values for the whole periods up to +20 days after the disclosure. The results of the paper imply consistently that the reorganized firms have no better performances compared to the similar normal firms, and the performances do not improve even after the completion of reorganization, which casts serious doubts upon the current forms of the institutionalized continuation of unprofitable firms.

Purpose: To urge the necessity of disclosure by identifying the relationship between the disclosure status of greenhouse gas emissions from domestic business sites and other indirect emissions to total emissions. Method: The 2021 emission data disclosed in the Carbon Disclosure Project (CDP) was collected by industry and emission category for comparative analysis. Result: The more companies that calculated and disclosed emissions by category within Scope 3, the more active they were in responding to or disclosing evaluation factors other than disclosure of emissions, and those companies were able to obtain higher grades in CDP and ESG evaluations. The number of Scope 3 calculations and disclosures was found to be high. In addition, there was a significant difference in the correlation between the number of Scope 3 disclosures by industry and the share of each scope out of the total in some manufacturing industries. Conclusion: As the number of Scope 3 disclosures, corporate ratings, and total emissions are proportional, it was confirmed that the higher the number of Scope 3 disclosures and GHG emissions, the higher the level of Scope 3 management. Based on Scope 3 emissions calculation and disclosure, effective emissions management and reduction activities are required.

Objectives: By comparing and examining how important issues concerning industrial health information for workers are viewed in other advanced countries, it is intended to ascertain problems in the approach found in Korean legislation and obtain legal and policy implications. Methods: The results of a survey were introduced and analyzed through a comparative method for each case after investigating in detail what and how important issues surrounding workers' right to know industrial health information are reflected in the legislation of Germany, the U.S., the U.K., and Japan. Based on the results of this comparative analysis, theoretical and policy implications and legal policy improvement tasks were drawn to strengthen workers' right to industrial health information for each case in Korea. Results: For access to industrial health information, most of the other advanced countries clearly stipulate a right to access for current and past workers and/or their representatives. As a result, workers or their representatives do not need to use the Information Disclosure Act to access exposure records, and there is no debate over the Information Disclosure Act. In other words, industrial health information is focused on ensuring free access to workers or their representatives and is not interested in reporting it to the government. Conclusions: In order to strengthen workers' right to know about industrial health, it is most important to address the legal issues related to this right, which is considered insufficient by comparative law. This should start with a concrete and effective definition of what and how to guarantee workers' rights to industrial health, such as the right to freely access industrial health information, including for retired workers and bereaved families of deceased workers.

Sensitive internal information has been transmitted in a variety of services of Internet environment, but almost users do not know what internal information is sent. In this paper, we intend to develop a new filtering system that continuously monitors the sensitive information in outbound network packets and notifies the internal user whether or not to expose. So we design a filtering system for sensitive information and analyze the implementation results. Thus users visually can check whether disclosure of the important information and drop the corresponding packets by the proposed system. The results of this study can help decrease cyber threats various targeting internal information of company by contributing to prevent exposure of sensitive internal information.

Epidemiological survey is an important means for the prevention and control of infectious diseases. Due to the particularity of the epidemic survey, 1) epidemiological survey in epidemic prevention and control has a wide range of people involved, a large number of data collected, strong requirements for information disclosure and high timeliness of data processing; 2) the epidemiological survey data need to be disclosed at different institutions and the use of data has different permission requirements. As a result, it easily causes personal privacy disclosure. Therefore, traditional access control technologies are unsuitable for the privacy protection of epidemiological survey data. In view of these situations, we propose a black box-assisted fine-grained hierarchical access control scheme for epidemiological survey data. Firstly, a black box-assisted multi-attribute authority management mechanism without a trusted center is established to avoid authority deception. Meanwhile, the establishment of a master key-free system not only reduces the storage load but also prevents the risk of master key disclosure. Secondly, a sensitivity classification method is proposed according to the confidentiality degree of the institution to which the data belong and the importance of the data properties to set fine-grained access permission. Thirdly, a hierarchical authorization algorithm combined with data sensitivity and hierarchical attribute-based encryption (ABE) technology is proposed to achieve hierarchical access control of epidemiological survey data. Efficiency analysis and experiments show that the scheme meets the security requirements of privacy protection and key management in epidemiological survey.

The purpose of this study was to explore relations between college students' dating violence perception and professional help-seeking attitudes and other factors that affect professional help-seeking attitude and their effect size. 508 students from a college in Chungcheong region responed to self-report questionnaires. Data were analyzed by Partial correlation coefficients and regression analysis using the SPSS 22.0 program. As a resullt, self-disclosure and anticipated utility on self-disclosure had positively effect on professional help-seeking attitudes. In contrast, violence perception, perceived social support, risk on self-disclosure and barriers to seeking help had negative effect on professional help-seeking attitudes. The total effect size was 46.1%, and the effect size of anticipated utility on self-disclosure was the largest, followed by risk on self-disclosure and barriers to seeking help. This study contributed to the broading of dating violence research topics and provided the directions to the endavour to increase the use of professional services among college students

A conflict of interest (COI) places people in ethical dilemma when providing consultation in a field of business, medical/pharmaceutical industry, research etc. Disclosure is a commonly adopted strategy for the adverse effect of COI, but previous studies have reported inconsistent results. This investigated whether individual differences in pursuing self-interest influence differently on consultation behavior during voluntary- or no-disclosure of COI conditions. A total of 190 adults participated in an on-line experiment which consisted of two tasks. On the 1^st task, participants were divided into either a role-oriented group or a self-interest group depending on their consultation choice on the task. On the 2^nd task, participants were required to choose whether to disclose COI to his/her virtual partner and provided consultation to them. No group differences were found in frequency of choosing voluntary disclosure. For the role-oriented group, the voluntary disclosure group provided unbiased information to the virtual partners than the no disclosure group. However, no group difference between voluntary- and no-disclosure group in the self-interest group. Implications and limitations are further discussed.

The purpose of this study is to investigate the role of interaction privacy management behavior (Use of IPCs), which has received relatively little attention. To this end, this study proposes an integrated model that theorizes the relationship between the main variables of the privacy calculation model and interaction privacy management behavior. Empirical analysis of this model shows that the use of IPCs lowers risks, increases benefits, and in turn promotes increased self-disclosure. These results have implications for expanding the theoretical logic of the privacy calculation model because users' self-disclosure includes not only the limited exposure proposed in the model but also unrestricted exposure through the use of IPC.
