The escalating demand for organized information resource management within organizations necessitates increased investment in information security (IS), as a single error can lead to information exposure incidents, underscoring the importance of IS compliance by insiders. The research aims to elevate IS compliance within the organization by examining the influence of the shared goal of information security policy (ISP), perceived ISP value and individual's fits on an insider's intention to comply with the ISP. Antecedent research in organizational behavior and IS led to a proposed hypothesis, tested using 366 obtained samples. The ISP shared goal's positive influence on ISP compliance intentions was evident from the test results, primarily through the perceived ISP value. Furthermore, the person-organization and demand-ability fit moderated the antecedent factors associated with ISP compliance intentions. Our findings suggest the methods for sustaining organizational IS levels by examining the requisite conditions from the viewpoints of the organizational environment, ISP values, and fits.

(Estimating Compensation for Personal Information Infringement) As the value of personal information increases, personal information infringements is more likely to happen. The compensation for personal information infringements needs to be calculated in the process of infringement remedy. However, as personal information is regarded as non-market goods with no exchange price and calculating the remedy for mental sufferings from infringements has no guideline, it is not easy to determine the compensation amount. In this study, we adopt Contingent Valuation Methods (CVM) to analyze Willingness to Accept (WTA) of each type of personal information. Also, this study attempts to examine a standard model for calculating compensation by applying JNSA JO Model of Japan, which is not prepared in Korea. This study does not simply present a plan of estimating compensation. By measuring the value of personal information, it could awaken companies and organizations to the importance of personal information security.

The identity of a subject could be established by justifying the educational value of the subject from various angles. Despite the huge necessity of information subject as one of basic disciplines, it cannot be said that the subject is considered valuable as a school subject. Even though that is selected as part of the revised curriculum and has textbooks of its own, it's actually disregarded in school education. The purpose of this study was to discuss the value of information literary subject as part of academic education in conjunction with computer science education, and to shed light on the value and objects of it as a school subject based on the characteristics of computer science education.

Although there have been cases of evaluating the value of specific companies or projects which have centralized on developed countries in North America and Europe from the early 2000s, the system and methodology for estimating the economic value of individual technologies or patents has been activated on and on. Of course, there exist several online systems that qualitatively evaluate the technology's grade or the patent rating of the technology to be evaluated, as in 'KTRS' of the KIBO and 'SMART 3.1' of the Korea Invention Promotion Association. However, a web-based technology valuation system, referred to as 'STAR-Value system' that calculates the quantitative values of the subject technology for various purposes such as business feasibility analysis, investment attraction, tax/litigation, etc., has been officially opened and recently spreading. In this study, we introduce the type of methodology and evaluation model, reference information supporting these theories, and how database associated are utilized, focusing various modules and frameworks embedded in STAR-Value system. In particular, there are six valuation methods, including the discounted cash flow method (DCF), which is a representative one based on the income approach that anticipates future economic income to be valued at present, and the relief-from-royalty method, which calculates the present value of royalties' where we consider the contribution of the subject technology towards the business value created as the royalty rate. We look at how models and related support information (technology life, corporate (business) financial information, discount rate, industrial technology factors, etc.) can be used and linked in a intelligent manner. Based on the classification of information such as International Patent Classification (IPC) or Korea Standard Industry Classification (KSIC) for technology to be evaluated, the STAR-Value system automatically returns meta data such as technology cycle time (TCT), sales growth rate and profitability data of similar company or industry sector, weighted average cost of capital (WACC), indices of industrial technology factors, etc., and apply adjustment factors to them, so that the result of technology value calculation has high reliability and objectivity. Furthermore, if the information on the potential market size of the target technology and the market share of the commercialization subject refers to data-driven information, or if the estimated value range of similar technologies by industry sector is provided from the evaluation cases which are already completed and accumulated in database, the STAR-Value is anticipated that it will enable to present highly accurate value range in real time by intelligently linking various support modules. Including the explanation of the various valuation models and relevant primary variables as presented in this paper, the STAR-Value system intends to utilize more systematically and in a data-driven way by supporting the optimal model selection guideline module, intelligent technology value range reasoning module, and similar company selection based market share prediction module, etc. In addition, the research on the development and intelligence of the web-based STAR-Value system is significant in that it widely spread the web-based system that can be used in the validation and application to practices of the theoretical feasibility of the technology valuation field, and it is expected that it could be utilized in various fields of technology commercialization.

This study examines information efficiency of financial information on the firm value for the listed manufacturing companies in Korea stock market in terms of timing pattern of information. We set 3 different test periods based on the financial statement released years - the current year, 90 days before financial statement announcement and the next year. We introduce using the stepwise regression method to examine the effect of financial variables on the stock returns. The financial variables include profitability ratio, growth ratio, stability ratio, activity ratio and market valuation ratio. The results of the study showed that both growth and profitability ratio affected the current year stock returns, while stability and activity ratio affected the next year stock returns. Growth rate of total asset affects both current year and next year stock returns. Our findings imply that the period in which financial information is reflected in the firm value, could vary with the characteristics of financial information.

This research suggested a new patent index based on patent citation technique using cited information, For this purpose, comparison research on library and patent information related citation database providing citation index was done. The information quality and meaning on the impact factor of JCR and the technology factor of CHI were reinterpreted. The former emphasizes the quality of continuous publication using relative citation frequency. The latter only emphasizes the information itself because it assesses the quality of patent characteristics. To overcome these difficulties, the latter re-authorized a relative quality to the organization possessing the patent using technology impact factor. Three new patent index were proposed on the basis of cited information to complement this. However, the comparative object was limited to American patent information that presented cited information of patent applied cases, and the comparison and research of domestic patent information could not be done.
