We implemented the document DRM applying role based access control(RBAC) mechanism for preventing the information leakage of a document which is transmitted in network environment. It must prevent to access document not related to user role and duty, and must allow operation to document for improving security, considering user role and security level according to a document importance. We improved the security of document DRM by adding to the access control module applying RBAC for satisfying security requirements. Though the user access document, our system allows operation authorizations to document by the user's role & security level and the security attribute of RBAC. Our system prevents indiscriminate access to the documents by user who is not associated with the role, and prevents damage the confidentiality and integrity.

According to knowledge-based view, knowledge is an essential strategic resource for a firm to retain sustainable competitive advantage. As knowledge is created and disseminated throughout the firm, the firm can enhance its capability to respond to new and unusual situations. Thus, a lot of companies actively manage their knowledge and intellectual capital. Especially, knowledge management (KM) activities in R&D organizations play a critical role in enhancing R&D performances such as innovation capability. In this regard, this study develops a theoretical model to examine the effects of R&D KM activities on R&D performance. The research model posits KM participation, knowledge management system (KMS) use, and community of practice (CoP) as the main activities of R&D KM. This study proposes that R&D shared knowledge quality and R&D KM satisfaction play a mediating role between R&D KM activities and its performance. The proposed research model was tested by using survey data collected from 248 employees in an R&D department. PLS (partial least squares) was employed for the analysis of the data. The findings of this study showed that R&D KM activities play a significant role in enhancing R&D performance. The findings revealed that R&D shared knowledge quality is not significantly related to R&D performance, while R&D KM satisfaction significantly influences R&D performance. The theoretical and practical implications of the findings were described.

Despite the relationship between cash flow, financial management, and project performance, no study examined the mediating role of financial management on the relationship between cash flow and construction project performance, especially in Kuwait. The goal of this study was to examine the impact of cash flow fluctuations on construction project performance, as well as the role of financial management in mediating this relationship. To accomplish these goals, the researcher employed a descriptive-analytical method to create a questionnaire of 31 items. The study's sample was chosen at random and includes (181) project managers and firm owners from contractors' companies in Kuwait. The study found a statistically positive and significant effect of cash flow variation on project performance from the perspective of Kuwaiti contractors at the significance level (0.05), as well as a mediated role of financial management in the relationship between cash flow variation and project performance. The research came up with a number of recommendations based on the findings, including the need for contractors to have a better understanding of cash flow to arrange project activities correctly and efficiently. Further studies may be included into the effect of cash flow forecasting (planning) and financial management (control) on various construction activities.

In their role as stewards of organizational information technology (IT), IT managers participate in crisis management activities. While much has been said about the power of technology in improving preparation for emergencies, the behavior of IT managers in crisis situations is not well understood. This paper addresses IT manager actions during the crisis response effort, when appropriate actions need to be taken at short notice. Recognizing that few guidelines exist for IT managers in these situations, we use recommendations from the crisis management literature in analyzing five earthquake cases from Japan and Taiwan. We identify several recommendations from this set for IT managers, which are related mainly to communications and leadership behaviors, suggesting that the IT manager role is a vital one in crisis response. The research additionally shows that recommendations from the crisis management literature have value also when applied to IT managers. Finally, we conclude on several ways that our understanding of IT manager crisis response could be developed by future research.

Objectives : This study developed and validated the local clinic Medical Doctor Role Stress Scale(MDRS). Methods : The interviews were conducted with 12 local clinic medical doctors to develop final preliminary questions. The scale was developed using statistical item analysis, exploratory and confirmatory factor analysis surveys with local clinic medical doctors in Seoul, Busan, Daejeon, and Gyeonggi province. Results : The MDRS developed in this study consisted of 14 items and three factors. The factors were role conflict, role ambiguity and role overload. The three factors explained 56.71% of the total variance, and the internal consistency of this scale was .90. The internal consistency for each factor was .81 ~ .90. Confirmatory factor analysis through a separate sampling met the fit criteria (CFI = .941, TLI = .927, RMSEA = .079, SRMR = .069). Conclusions : The results indicate that this scale is a reliable instrument for assessing local clinic medical doctor role stress.

This study examined whether family-friendly policies at work moderate the association between fathers' gender role attitudes and their affectionate parenting behaviors. The data was derived from the Panel Study of Korean Children. The samples included 1,164 fathers who participated in the seventh and eighth panel studies. To analyze the data, Pearson's correlations, multi-regression, and simple slope analysis were conducted using SPSS 25.0 and PROCESS Macro. The key findings of the study were as follows: Among family-friendly policies, the paternity leave and a flexible work system moderated the association between gender role attitudes and affectionate parenting behavior. Such family-friendly policies strengthened fathers' affectionate parenting, and gender role attitudes tended to be egalitarian in this case. The results of the present study showed that fathers' affectionate parenting behavior reflected their egalitarian gender role attitudes and particularly emphasized the importance of the role of family-friendly policies in providing fathers with autonomous time use.
