Nursing students experienced anxiety and fear of building relationships with psychiatric patients due to lack of professional knowledge about metal illness and skill to take care of the patients. The simulation education is known as an effective teaching-learning method since being performed in a non-threatening environment similar to clinical setting. The purpose of this nonequivalent quasi-experimental study was to identify the effect of simulation on anxiety and self-confidence about the psychiatric-mental health nursing practice. The third year nursing students at a three year nursing program were participated in this study. For the experimental group (N=28) the simulation education using the standardized patient based on the scenario for patients with schizophrenia was performed, and for the control group (N=18), the debated education applying the case study same as for the experimental group was made in the class. Using SPSS, t-test and ANCOVA were analyzed to compare the anxiety and self-confidence between the experimental and control groups. As a result of the study, the anxiety score on psychiatric-mental health nursing clinical practice of the experimental group significantly decreased, compared to that of the control group, but the self-confidence score for the performance of psychiatric nursing care showed no significant differences between the groups. Accordingly the simulation education can be an effective educational method to reduce anxiety about psychiatric-mental health nursing clinical practice for nursing students.

Link reduction algorithms such as pathfinder network are the widely used methods to overcome problems with the visualization of weighted networks for knowledge domain analysis. This study proposed NetRSQ, an indicator to measure the goodness of fit of a link reduction algorithm for the network visualization. NetRSQ is developed to calculate the fitness of a network based on the rank correlation between the path length and the degree of association between entities. The validity of NetRSQ was investigated with data from previous research which qualitatively evaluated several network generation algorithms. As the primary test result, the higher degree of NetRSQ appeared in the network with better intellectual structures in the quality evaluation of networks built by various methods. The performance of 4 link reduction algorithms was tested in 40 datasets from various domains and compared with NetRSQ. The test shows that there is no specific link reduction algorithm that performs better over others in all cases. Therefore, the NetRSQ can be a useful tool as a basis of reliability to select the most fitting algorithm for the network visualization of intellectual structures.

TIMSS (Trends in International Mathematics and Science Study) aims to produce reliable and internationally comparable indicators of student achievement. The TIMSS science achievement scale summarizes student performance on test items designed to measure a wide range of student knowledge and proficiency. This study analyzed Korean middle school students' science achievement at the advanced and high international benchmarks of the four benchmark levels of the benchmarks classified in TIMSS 2003 in light of science content areas (physics, chemistry, biology, earth science, and environmental science) and item characteristics. The average percent correct on items at the advanced benchmark by Korean students was highest in physics followed by earth science, biology, chemistry, and environmental science, whereas internationally the order was earth science, chemistry, biology, physics and lastly environmental science. Korean students performed relatively better in physics yet somewhat worse in chemistry than other top-performing countries. According to item analysis, Korean students reaching the advanced international benchmark understood some fundamentals of scientific investigation, but demonstrated weakness in written explanations of scientific principles, abstract science concept comprehension, and application of scientific concepts to solve quantitative problems. In addition, Korean students reaching the high international benchmark demonstrated relative weak conceptual understanding of ecology compared with other countries.

The Korean Science Education Standards (KSES) were developed to support the establishment of a domestic national science curriculum to respond to future social and environmental changes as an action plan to improve scientific literacy in the context of science education. In this study, we analyzed the relationship between KSES and the 2022 revised middle science curriculum focusing its learning contents and learning objectives and sought effects of the successful implementation of the curriculum. As a result, the content system of the 2022 revised middle science curriculum was highly related to the categories of knowledge in KSES. Attempts to deal with the content related to the nature of science was also confirmed through content elements in science and society domains. In the case of achievement standards, it was focused on some areas of the performance expectations in KSES, but the level of statement of the achievement standards closely matched the level of middle school students as suggested by KSES. From these results, it was possible to confirm the high relationship between the 2022 revised middle science curriculum and KSES, as well as the possibility of using KSES as an international indicator for establishing future science education plans.

We conducted this study to identify factors that influence college students' willingness to perform CPR. The subjects of the study were 229 college students from J City and D City. A URL was distributed to those who agreed to the study and a non-face-to-face survey was conducted using a questionnaire form. The research results were analyzed using SPSS/WIN 23.0. 155 out of 229 people (67.7%) responded that they would perform CPR if they found a patient suffering from cardiac arrest. Factors that differences between the CPR performing group and the non-performing group include gender, grade, experience of practice, number of CPR training, period of last CPR training, Have a CPR certification, and knowledge of CPR, Confidence of CPR. There was a statistically significant difference(p<0.05). Factors affecting the willingness to perform CPR include those who have actual experience of CPR, those who have CPR certification, and the higher their confidence in CPR, the higher the willingness to perform CPR. Accordingly, in order to increase confidence in CPR, we emphasize the importance of realistic performance experience and propose the development and application of various educational methods to increase the implementation rate through sufficient simulation learning.

Recently an opportunistic incremental relaying (OIR) system has been studied for improving the performance degradation in fading channel. However there are few studies on power control in the system, and the studies are assumed perfect knowledge of the all channels at transmitters. The assumption that the source know all channel information is difficult in practical channels. Therefore, in this paper we assume that the source knows partial channel information and propose a modified truncated channel inversion (TCI) power control scheme for the OIR system. We derive the channel capacity of the proposed system and perform Monte Carlo simulation. It is noticed that the proposed OIR system has better capacity than that of the power controlled system with direct path only, and the capacity increases with the number of relays. The power controlled OIR system gained more capacity of 29.7%, 32.7%, and 33.5% than that of the system with direct path only for the number of relays of 1, 3, and 5, respectively. The results from this paper can be applied to the estimation of a theoretical capacity for the currently operating cellular systems when they adopt the IOR system.

Recently, accumulation of technology, transfer, absorption, and commercialization is being significantly recognized as a key factor for sustainable growth of the 21st century global economy. The government established "Technology Transfer and Commercialization Promotion Act" In order that the technology developed at public research institutions can be transferred to the private sector and commercialized; the technology developed in the private sector can be traded and commercialized. Also, the Article 14 of "Technology Transfer and Commercialization Promotion Act" is concerning technology transfer agents' registration, promotion, and support: it introduced the special status system of technology transfer agents and the government registers, manages, and supervises it. In most developed countries, the technology transfer agency is transferred to the private sector and it is referred as a technology transfer agent or technology broker. In the domestic market, despite the introduction of the above special status system and the building a various organization and transfer medium system for boosting the market's revitalization, some problems occurred; because the registration system of a technology transfer agent and legal basis and system about its following-up control fall short. For example, recently technology transfer-related performance exemption has brought the activation of technology transfer agent's registration, but there was the limit of selecting the expert above a certain level. Therefore, some countermeasures for this are urgent, In addition, through a compulsory training completion system before the technology trade agent registration is prepared, a short period of curriculum was not sufficient to provide applicants various specialized knowledge. In this research, it is considered about the reform of technology transfer agent through its comparative study in China and Korea. Some improvements are suggested for expanding the market of technology transfer commercialization, assuring the agents' service and strengthening the competitiveness.

User involvement in New Service Development(NSD) has attracted the limelight as a good method, but we still lack an empirical analysis of the effectiveness of user involvement. In addition, positive and negative determinants of user involvement in NSD have not often been dealt with in past research, and this deficiency has been identified as a barrier to the effective utilization and diffusion of user involvement in NSD. To our knowledge, this is the first study to empirically investigate the degree of implementation of user involvement in NSD, the effectiveness of user involvement, and the utilization strategy in the digital content industry. First, we reveal that ordinary user involvement is more effective for NSP performance than lead users or business partner companies. Second, we empirically demonstrate that the effectiveness of involving lead user and ordinary user in NSP is different according to the new service type and service development stage. Based on the results of our analyses, we suggest some strategic directions for the companies who want to newly adopt or improve their current level of user involvement in NSD. We expect that the implications of this study will be utilized for efficient diffusion of user involvement in NSD and will eventually contribute to tangible achievements for companies in the digital content industry.

The service that has been recognized as both a non-productive activity and auxiliary activity of manufacturing have become the driving force of the customers' demand with the 'service' itself. The service base is expanding and evolving rapidly. It is important to look at changes in service concepts to understand service systems. Because the service system itself has a cyclic nature based on the concept of service, it can help in the study and the "how" of service by looking at changing the system according to the evolution of the service concept. The ability to organize and utilize relationships is considered to be an important factor for managers in the service economy era. However, the attention of corporate is focused on their internal capabilities and they are familiar with external resources (knowledge and competence of customers). In this case study for each type of service, we analyzed the activities of interacting service providers-consumers in service relationship, and constructed a new service system model emphasizing intangible value and long-term outcome. This study is worth re-examining the role of customers in today's service economy era and actively utilizing a new service model for business performance.

Game industry, one of cultural-content industry which is considered as a typical knowledge-based industry and creative industry, is not like the overseas expansion of traditional manufacture, and has different strategy and performance of export expansion through product or project-based strategy. Therefore, it should be approached by each content unit, and necessary to look at the factors that make their decision makings of foreign market entry vary. This study focuses on discovering creativity, absorptive capacity and strategic orientation(market orientation and innovation orientation) which affect the difference of distribution's decision making of entry into foreign market in game industry This paper examined 252 cases of online games in order to investigate creativity, absorptive capacity and strategic orientations for each foreign market and what entry type(among licensing, joint distribution, exclusive distribution) they chose according to the products developed in team level. This helps us analyze the factors affecting market orientation and innovation orientation in the perspectives of creativity and absorptive capacity in comprehensive way, and notice the phenomena which use different foreign distribution strategy though there are company incorporated abroad and their results. This study supplements the limit of the existing Resource-Based View, Resource-Dependent View, and traditional international business theories such as Transaction Cost Theory or OLI Paradigm(Eclectic Framework), and proves how company could reduce asymmetry of uncertainty and information in creative industry and whether they accomplish successful overseas expansion according to strategic orientations.
