Purpose: The purpose of the study was to understand and describe the hospital workers' experience related to the hospital evaluation program implemented in Korea between 2004 and 2009. Methods: During 2010, data were collected using focus group interviews. Four focus group interviews were held with a total of 28 hospital workers participating. All interviews were recorded and transcribed as they were spoken, and data were analyzed using qualitative content analysis. Results: Nine themes emerged from the analysis: 1) Positive change in the necessity of the evaluation; 2) Improvement in the hospital system, facilities, and human resources; 3) Unity through cooperation among departments; 4) Nursing work overload; 5) Lack of physicians' awareness and responsibilities; 6) Unfair and unrealistic evaluation items; 7) Lack of credibility of the outcome; 8) Shifting responsibility for negative outcomes to the workers; 9) Lack of pragmatic utility. Conclusion: The results of the study demonstrate that the hospital evaluation program played a key role in improving some work environments and communication among departments. At the same time, they show various negative themes resulting from the context of very authoritarian hospital systems and a connection-oriented society in Korea.

Based on the research of the Public Welfare Games 'Mountaineering LightsUp', which is the main theme of helping the disadvantaged in society, this study uses the questionnaire method to obtain user data, and collects the data by using AMOS analysis for the effect of game interest elements on the experience of players. The results showed that the interesting elements (goal, obstacles, sense of belonging, atmosphere, story, information, and player to player communication) of the game were positively influenced by the experience of the game. And the questionnaire showed that the game still had problems such as playing simple, difficulty, lack of popularity, lack of feedback, and lack of storytelling. This paper also puts forward some proposals for these deficiencies. In future research, the research sample will be expanded, the research content will be improved, and the future Public Welfare Games will be designed and developed.

In recent years, there have been tries to open public data from various government agencies along with publicization of public information for the public interest. In other words, various kinds of electronic data generated and collected by the public institutions as a result of their work are opened in the public portal sites. However, users who use it are limited in their use of big data due to lack of understanding of data format, lack of data processing knowledge, difficulty in accessing and managing data, and lack of visualization data to understand collected and stored data. Therefore, in this study, we propose a big data collection, storing and visualization platform that can collect big data provided by various public sites using data set URL and API regardless of data format, re-process collected data using XML structure.

Online video conferencing systems such as Zoom and Discord are mainly used for non-face-to-face work due to their good accessibility and lack restriction of space. However, most online video conferencing systems are difficult to interact in both directions, and problems such as difficulty in communication and lack of immersion are emerging in participants who use them. On the other hand, Metaverse, which has attracted attention with the development of spatial computing, enables smooth interaction like the real world in the three-dimensional virtual world by utilizing hearing, visual, and touch information. In this paper, we propose a method of utilizing the metaverse platform to improve the problem of lack of immersion in the existing online video conferencing system. Through the proposal method, platform users can share and check each other's work screens in a virtual space and exchange various data. In order to improve participants' of immersion, the environment and improvement plan of the metaverse platform were constructed and compared with the existing online video conferencing platform.

In this research, we investigated the support system and professional development in teaching practices of beginning science teachers through instructional consulting. Using open-ended interviews with the participating teachers and group discussions taking place on a regular basis to analyze and compare classes of six beginning teachers, we analyzed beginning teachers' professional development efforts centering around their teaching practices. The group discussion consisted of 6 beginning teachers and another 6 experienced teachers, they discussed and cross-analyzed beginning teachers' 9th lessons on middle school science unit, 'Work and Energy.' The characteristics of beginning science teachers' professional development drawn from this research are: (1) beginning teachers' teaching practices they were taught, (2) lack of reflection on their teaching practices, (3) no guidance for beginning teachers regarding ways to teach, (4) lack of communication between teachers about teaching science, and (5) lack of time for instructional preparation due to other heavy workload. Suggestions for ways to improve and support beginning teachers' professional development are discussed with experienced teachers. Required conditions for an effective induction program are also discussed.

Purpose : This study sought to explore intensive care unit (ICU) nurses' perceptions regarding the disclosure of patient safety incidents (DPSI) and identify the relationship between the perception of DPSI and communication barriers. Methods : This study used a descriptive research design. A total of 110 ICU nurses from a tertiary hospital were surveyed online between September 14 and October 5, 2022. The mean DPSI score ranged between 1.0 and 4.0, with a higher score indicating a higher perception of DPSI. Results : The mean score for ICU nurses' perceptions of DPSI was 2.92 (SD=0.37). Among the characteristics of ICU nurses, differences were observed in perceptions of DPSI according to gender, age, total work experience, and ICU work experience. Communication barriers among ICU nurses were negatively correlated with negative results as a sub-factor of perceptions of DPSI. Ambiguity in the nurse's position, lack of confidence, differences in perspectives with patients, and inadequate nurse-patient relationships as sub-factors of communication barriers exhibited a negative correlation with negative results as a sub-factor of perceptions of DPSI. Conclusions : ICU nurses' perceptions of DPSI and the sub-factors related to communication barriers are negatively related to DPSI. To improve ICU nurses' perceptions, open and non-punitive circumstances, staff education, practical guidelines, and support systems are required.

Users may experience a sub-type of motion sickness, called cybersickness, when interacting with virtual reality (VR) applications in the state of wearing head mounted display (HMD) devices. Although the root cause of cybersickness is still unclear, it is believed to result from a sensory mismatch between visual and vestibular systems. However, there is a lack of studies developing data collection and analysis systems to measure cybersickness. In this paper, therefore, a system is designed that collects electroencephalography (EEG) and physiological data from a user wearing a VR HMD device through an internet of things (IoT) platform and decides whether a user experiences a symptom of cybersickness, namely dizziness, or not by using a decision threshold. Experimental results showed that the proposed system achieved about 92% accuracy of a dizziness detection when considering 14 participants.

Wireless communication system for firefighters has an important role as the last communication method between the commander and the firefighters in disaster sites like fire. But the operation of Gyeongnam wireless communication system is installed, and maintained and controlled without criteria for the selection of a transmitting station and the analysis of propagation environment because of the lack of budget and the absence of professional personnel. To improve the performance of the radio station, this paper theoretically calculated free space loss of UHF 400 MHz band used by all firefighters in Gyeongnam and diffractions caused by single and multiple obstacles and computed the error after comparing the results of the actual measurement to those of simulation with FRAS operated by KFL. In the results, Deygout model was the most consistent with the actual measurement for 400MHz band in Kimhae site.

Currently, the management system of wastewater treatment facility has magnified due to the stringent regulations for the protection of the environment. However, wastewater treatment system is insufficient in wastewater quality monitoring technology in specialized. Above all it aim one-to-one data transmission instead of one-to-n data transmission through sensor and network. And then, it lack compatibility toward communication system between different. Mainly it has observed detecting system of manual system. In this paper, we studied protocol technology about efficient data transmission between sensor and integration interface of water quality detecting interface for automated sensor network integration interface in water restoration facility. Therefore, we proved the possibility of efficient data transmission from communication system of different type through monitoring implementation of sensor network integration interface.
