The present study is a descriptive study to investigate nurses’perception of barriers to research utilization. A total of 274 participants in this study consisted of registered nurses working in a large, urban and academic medical center. A questionnaire packet containing the Barriers Scale, and a demographic profile was distributed to nurses and they were asked to return the packet to a return-box in the Nursing Office after completion. The greatest barrier was insufficient time on the job to implement new ideas. Next was ‘implications for practice are not made clear'. Also the item of the English language in research articles was considered to be the ninth barrier. The greatest mean score of each of the sub-scales was the communication factor. The were followed by the organization, research, and nurse factors. Compared with the means from other studies, the mean scores of the communication and research factors were higher in this study. Nurses who had not taken a class of research methods found the communication and research factors as a higher barrier than those who did. Also, nurses who did not participate in a conference last year perceived the research factor as higher than those who did. It is recommended that English and research classes should be strengthened in educational nursing programs. The researchers should also describe the section of implication for practice as more detail and clearer for the understanding of nurses; Lastly journals in a libraries or online journal systems should be easily accessible.

Government R&D Project Management in Korea has had considerable difficulties because of the lack of project monitoring systems and insufficient communication. The National Program for Tera-level Nanodevices (TND Program) is a ten-year R&D program for commercialization in the area of nano technology. Collaboration and communication among the various participants such as business companies, universities, and government R&D institutes are key success factors in this R&D program. TND Program office has developed a Web-based project management system. This system consists of mostly four sub-management functions: (1) Milestones management of all R&D projects; (2) DR (Design Review) management as the mechanism for checking the performance against milestones; (3) Project activity management using the WBS (Work Breakdown Structure); (4) Budget management. Additionally, it also has many R&D supporting functions such as technology information bulletin board, community management, and visual summary of project progress and performance. This system is effective for monitoring research project as well as measuring project performance of the overall research program. This Web-based system has become the useful tool of R&D moving target mechanism and effective communication and collaboration tool. System features and adoption process of the system are also suggested.

Recently, it is difficult to communicate face-to-face during work due to corona. To solve this problem, various platform-type communication tools are being created. For this study, we surveyed office workers in the 2040 field to find out what tools they are using the most and what are the most difficult problems with their collaboration. According to the analysis, practitioners use familiar tools that they used frequently for their work, and during the collaboration, poor communication is the most difficult. In this study, we would like to identify the tools and uses that are currently being used by domestic designers and developers in collaboration, and suggest directions for solving problems.

A wide-band multiple-input multiple-output (MIMO) antenna with dual-band (2.4 and 5 GHz) operation is proposed for premium indoor access points (IAPs). Typically, an omni-directional pattern is used for dipole antennas and a directional radiation pattern is used for patch antennas. In this paper, both antenna types were used to compare their performance with that of the proposed $2{\times}2$ MIMO antenna. We simulated and measured the performance of the MIMO antenna, including the isolation, envelope correlation coefficient (ECC), mean effective gain (MEG) for the IAPs, and the throughput, in order to determine its communication quality. The performance of the antennas was analyzed according to the ECC and MEG. The proposed antenna has sufficient performance and excellent characteristics, making it suitable for IAPs. We analyzed the communication performance of wireless networks using the throughput data of a typical office environment. The network throughput of an 802.11n device was used for the comparison and was conducted according to the antenna type. The results showed that the values of the ECC, MEG, and the throughput have unique characteristics in terms of their directivity, antenna gains, isolation, etc. This paper also discusses the communication performance of various aspects of MIMO in multipath situations.

A local area network (LAN) is a computer network within a small geographical area such as a home, school, computer laboratory, office building or group of buildings. A LAN is composed of interconnected workstations and personal computers which are each capable of accessing and sharing data and devices, such as printers, scanners and data storage devices, anywhere on the LAN. LANs are characterized by higher communication and data transfer rates and the lack of any need for leased communication lines. Communication between remote parties can be achieved through a process called Networking, involving the connection of computers, media and networking devices. When we talk about networks, we need to keep in mind three concepts, distributed processing, network criteria and network structure. The purpose of this Network is to design a Local Area Network (LAN) for a BAEC (Bangladesh Atomic Energy Commission) Head Quarter and implement security measures to protect network resources and system services. To do so, we will deal with the physical and logical design of a LAN. The goal of this Network is to examine of the Local Area Network set up for a BAEC HQ and build a secure LAN system.

Purpose: This study examined the influence of nurses' communication competency, critical thinking disposition, and perception of patient safety culture on patient safety competency in armed forces hospitals. Methods: A crosssectional design was employed with a convenience sample of 204 nurse officers from four armed forces hospitals in South Korea. Data were collected through a self-administered questionnaire from August 10~23, 2019, and analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and multiple regression. All analyses were conducted using SPSS for Windows 21.0. Results: Patient safety competency scores were 4.35±0.40 for patient safety attitudes, 3.63±0.64 for patient safety knowledge, and 3.94±0.51 for patient safety skill. Communication competency, critical thinking disposition, and perception of patient safety culture were positively correlated with patient safety competency. Communication competency (β=.30, p=.002) and perception of patient safety culture (β=.24, p=.001) were identified as particularly important factors influencing patient safety competency. Conclusion: This study's results suggest that education programs to enhance communication competency and patient safety culture could increase patient safety competency among nurses in armed forces hospitals.

A majority of 4G Mobile communication manufacturers have launched separated-type base stations composed of DU (digital unit) and RU (ratio unit). DUs are usually installed in the central office, while RUs with antennas are installed on the top of building or pole. Therefore, the allowable distance between DU and RU is very important for cell planning. In this paper, we analyze the allowable distance between DU and RU induced by closed-loop MIMO (mulitple input multiple output) technology in 4G FDD (frequency division duplexing) mobile communication systems. In conclusion, the distance limit between DU and RU is dependent on the frequency of the wireless communication, and the allowable distance is about 11 km when assuming the operating frequency is 2 GHz.

Workplace bullying is becoming one of social issues. The aim of the present study was to investigate whether the contextual variables(communication climate, social climate) moderate the relations between the individual variables(trait anger, social avoidance) and workplace bullying victimization. The self-report data of 207 office workers(115 men, 92 women) in Seoul and Gyeonggi-do was analyzed. The results of hierarchical regression indicate that trait anger positively predicted men's workplace bullying victimization only when social climate is bad. Social avoidance positively predicted men's bullying victimization only when communication climate is good. There was no moderating effect of the contextual variables among women. Trait anger positively predicted women's workplace bullying victimization only when considering communication climate as a contextual variable. Social avoidance has no significant effect on women's workplace bullying victimization. However, both communication climate and social climate negatively predicted women's victimization. The implications and suggestions for prevention and intervention of workplace bullying were discussed.
