  • Anti-HIV-1 activities for the extracts (buthanol, hexane, chloroform, and water) of medicinal plants widely used in the folk medicine were evaluated for screening of anti-AIDS agents. The activities of the extracts to inhibit HIV-1 replication were also analyzed. The 50% effective concentration (EC50) of inhibition activity of the p24 production for chloroform extract of Saphora flavescens, chloroform extract of Herba ephedrae, and hexane extract of Pachyma hoelen Rumph showed 5.8, 29.9, and 37.3 2g/ml, respectively, as good activities. Hexane extract of Sophora flavescens, buthanol extract of Tulipa edulis, hexane extracts of Tulipa edulis, Herba ephedra, and Pachyma hoelen Rumph in the 50% cytotoxic concentration ($CC_{50}$) in inhibition activities of recombinant HIV-1 RT showed 12.9, 19.5, 11.6, 12.0, and 36.8 % at concentration of 200 ${\mu}g$/ml, respectively, as good activities. From these results, chloroform extract of Saphora flavescens, chloroform extract of Herba ephedrae, and hexane extract of Pachyma hoelen Rumph were very effective against HIV-1 among all extracts tested. Therefore, we expect these plants will be a useful for anti- HIV-1 therapeutics in future.

  • This research aims to examine the predictive power of multiple online stock message boards, namely, NAVER Finance and PAXNET, which are the most popular stock message boards in South Korea, in stock market activities. If predictive power exists, we then compare the predictive power of multiple online stock message boards. To accomplish the research purpose, we constructed a panel data set with close price, volatility, Spell out acronyms at first mention.PER, and number of posts in 40 companies in three months, and conducted a panel vector auto-regression analysis. The analysis results showed that the number of posts could predict stock market activities. In NAVER Finance, previous number of posts positively influenced volatility on the day. In PAXNET, previous number of posts positively influenced close price, volatility, and PER on the day. Second, we confirmed a difference in the prediction power for stock market activities between multiple online stock message boards. This research is limited by the fact that it only considered 40 companies and three stock market activities. Nevertheless, we found correlation between online stock message board and stock market activities and provided practical implications. We suggest that investors need to focus on specific online message boards to find interesting stock market activities.

  • Purpose: This study was intended to identify the impact of awareness of patient participation culture on patient safety nursing activities among nurses in small-to-medium-sized hospitals. Methods: A total of 181 nurses working in G Metropolitan City were selected. Data were collected from August 7 to September 30, 2023, and analyzed using an independent t-test, one-way ANOVA, Pearson's correlation, and multiple regression. Results: The mean scores for awareness of patient participation culture and patient safety nursing activities were 2.95±0.95 and 4.50±0.41, respectively. A significant correlation was found between awareness of patient participation culture and patient safety nursing activities (r=.51, p<.001). As subcategories of awareness of patient participation culture, nursing practice environment (r=.36, p<.001), information-sharing activity (r=.38, p<.001), and attitudes toward patient participation (r=.47, p<.001) were also significantly correlated with patient safety nursing activities. Patient safety nursing activities were influenced by nursing practice environment (β=.24, p=.001), information-sharing activity (β=.15, p=.044), and attitudes toward patient participation (β=.28, p<.001). The explanatory power was 28.0% (F=24.10, p<.001). Conclusion: This study recommends the development of 1) training programs to enhance nurses' awareness of patient participation culture and 2) interventions to encourage patient participation in safety practices.

  • With the rapid change in technology, it is important to create business opportunities from technology. Many leading companies have tried to improve their competence from capturing those opportunities, which is called TOD (Technology Opportunity Discovery) activities in this research, by identifying emerging technologies or assessing economic and market potential of technologies. Academics have also been interested in the TOD activities but most of the previous studies have focused on developing methodologies or guidelines for TOD. Little effort was given to understanding the current status of TOD activities, which is indispensible to develop effective methodologies for TOD. Therefore, this study aims to investigate the current states of TOD activities, particularly focusing on SMEs, which are the main actors of national innovation system. For the purpose of investigation, firstly, TOD process was defined, and then, based on the process, three main activities of TOD, which include identifying the motivation of TOD, collecting information for TOD, and analyzing the collected information activities for TOD, were examined using a survey method. Finally, the analysis results were used to understand the SMEs' needs and difficulties on TOD activities. Research findings are expected to provide useful information for the future studies on TOD and also can be used to develop a policy for SMEs.

  • The purpose of this study is to empirically analyze the impact that occurs when Korean organizations make practical use of various information technology tools and systems in the knowledge management process, such as sharing, learning and creating knowledge. Such a process is usually made through online and offline knowledge management activities. This paper also verifies how the externalization of tacit knowledge, and the internalization of explicit knowledge via the Internet and offline socialization activities have altered the mechanisms of knowledge transfers inside organizations. For the research, a survey was conducted on the satisfaction and usability levels of information technology, and the impact of IT usage on the results of knowledge management activities and knowledge transfers. 622 Korean organizations were surveyed, including major listed firms and public organizations. The results were examined as an online/offline integration process using SECI's Model proposed by Nonaka (1994, 1995). The analysis shows that information technology satisfaction and the usage of information technology help accelerate the pace of the knowledge flow and amplify the volume of the knowledge transfer by boosting the externalization and internalization processes-also known as knowledge management activities. However. there is no distinct correlation between information technology and socialization, an offline knowledge transferal activity. In particular, the quality of knowledge-an end result of knowledge transfer-does not improve merely by the externalization of online knowledge and instead requires the internalization of knowledge processes. Above all, the research reveals that offline socialization processes vastly contribute to the improvement of knowledge quality. This paper suggests that in order to ensure a transfer of quality knowledge, an organization or a company should focus on the use of information technology rather than the satisfaction level of information technology, and that knowledge transfers via the Internet has limitations in creating high quality of knowledge. For an organization to ensure the transfer of high-quality knowledge, the organization should not entirely hinge the transfer of knowledge online, as it is essential to have an offline method-a form of socialization such as a 'community of practice.'

  • This study focused on the concept of organizational learning as a prior variable of innovation activities, and reviewed the relationship between organizational learning, innovation and management performance. According to prior studies, the ability to perform these activities may be enhanced through organizational learning, as the success of the innovation requires activities to acquire and share knowledge within the organization. In other words, organizational learning is playing a role as a precursor to innovation. Therefore, in this study, the effects of organizational learning on management performance are to be verified through the mediation effect of product and innovation activities. Organizational learning provides various definitions and components for each scholar, but this study consisted of a series of knowledge acquisition, information distribution, information analysis and process memory using the framework of the learning ability analysis by Levitt and March(1988) and Huber(1991), Innovation was also divided into product innovation and process innovation, and measured with sub-variables such as presentation of new products and improvement activities to increase productivity. Management performance was measured as financial and non-financial performance. To verify the effects of the mediation, we used a three-step regression analysis procedure of Baron and Kenny(1986)'s and a sobel-test. Empirical studies show that organizational learning has a positive effect on management performance and that knowledge acquisition and information distribution, which are the early stages of learning activities in the lower variables, affect performance through product innovation. Based on the results of the above empirical study, the implications, limitations of the study and future research directions were presented.

  • The present study aims at a systematic access to EC information. EC information is the outcome of the complex organizations, the continuous changes in functions and the subsequent changes in policies. An attempt for an effective approach to the information requires the examination of the organizational structures and changes, the processes involved in formulating and implmenting the information policies, and the infrastucture for information. Information activities of the major organizations of EC have been examined with a special reference to the Commission of European Communities. The Commission is the EC institution from which the majority of the EC's documentation originates. The information functions of the Commission have been studied in such categories as information production and distribution, authorizing services, and information services to the public.
