The purpose of this study was to analyze the effects of internal organizational culture attributes on job performance and job satisfaction. Data collection was conducted from December 8, 2014 to December 20, 2014 through a self-enforced questionnaire at 500 general hospitals in Gyeonggi-do. First, the organizational cultural attributes of hospitals had a statistically significant effect on job performance. Second, organizational cultural attributes had a statistically significant effect on job satisfaction. Third, job performance had a statistically significant effect on job satisfaction. For communication, organizational development and the future of the organization as well as organizational attributes and systems of the organization were shown to increase job performance and job satisfaction, communication with seniors and colleagues, roles, and responsibilities between departments. Organizational culture had more organizational attributes than individual ones, which affects the work and behavior of the organization members. Therefore, in order to survive competition, hospitals require accurate diagnosis of hospital organization culture, maximize effectiveness of organization culture, and a desirable hospital culture. In addition, management should provide employees with a clear mid- to long-term vision to ensure that the objectives of the hospital and the goals they pursue are consistent.

With the aid of the increasing interests of Context-aware Augmented Reality Agent (AR Agent), various researches of AR Agent have been performed to explore the possibility of the agent as novel interface and the entity responding autonomously by user's input. However, in previous works, AR Agents are lack of specific method for using various contextual information. To revolve around those problems, we propose the Behavior Generation System for Context-aware AR Agent using layered architecture. Based on Belief-Desire-Intention (BDI) model and Hierarchical Task Network (HTN) searching, the sequence of agent behavior has been selected in behavior planning layer. Then, the agent evaluates appropriateness of behaviors using previous behavior and the type of input before activation. This behavior generation system can be applied for edutainment, game, and assistant agent, which need intuitive and effective behaviors to convey information. Through this research, we expect that the Context-aware AR Agent could support for not only information delivery, but also the capability of effective communication for user.

Collaborative programs are tools designed to support multiple people working together, enhancing collaboration and communication efficiency, improving productivity, and overcoming the constraints of time and place. In the endemic era, many companies and individuals prefer using collaborative programs. These programs often handle sensitive information, such as work content, documents, and user data, which can cause significant damage if leaked. Exploiting this, various attack scenarios have emerged, including malware attacks disguised as collaborative programs, exploiting vulnerabilities within these programs, and stealing internal tokens. To prevent such attacks, it is essential to analyze and respond to potential threats proactively. This paper focuses on Notion, a widely used collaborative program, to collect and analyze artifacts related to user information and activities in both PC and Android environments. Based on the collected data, we categorize critical information, discuss potential threats, and propose countermeasures.

This study presents the design and manufacture of a self-contained breathing apparatus SCBA wireless communication module with a multipoint simultaneous full-duplex communication system to enable communication between team members wearing the SCBA system. It is necessary for fire-fighters to wear the SCBA system during extinguishing and rescue work at the fire site. Evaluation of the team communication module confirmed the feasibility of communication over more than 500 m in the test condition based on the line of sight. By implementing the Ad-hoc function, it was confirmed that the communication distance could be extended to 128 m by automatic routing up to 3 hoc. The vertical distance inside the building for successful communication was up to the 5th floor in the open staircase and up to the 3rd floor in the partitioned staircase. Furthermore, the performance testing of the communication module assuming a fire situation, confirmed that five team members correctly recognized the standard abbreviation of fire and wireless communication without a separate PTT key operation. In addition, the flame resistance was verified by exposing the module to a flame at 950 ± 50 ℃ for 5 s and then immediately extinguishing the flame.

Since quality assurance and enhancement (QAE) raises the fundamental issue of the survival of higher education institutions and national competitiveness, guides on quality assurance (QA) are popular both domestically and worldwide. Despite the focus in many countries on trying to establish and implement QA systems, no clear investigation has been conducted on what actually happens in the institutions. Therefore, the present study examines the quality control system of the UK at an institutional level by focusing on the case of Scotland QAE. As Scottish QAE especially emphasizes student engagement and quality culture, this study investigates the present QAE situation in the institution and current ideas for better future practices by analyzing the perceptions of internal stakeholders' from the University of Edinburgh, School of Education, based on the stakeholder theory and implications for other contexts. The stakeholder analysis results demonstrate the successful application of QAE with a high level of understanding and stakeholder interest. However, the current strategy is missing certain opportunities for staff and students. Therefore, further information disclosure, formative evaluation, better communication and administrational supports are required for improved practice.

The Intersection is inner traffic facilities and the space where the roads are intersected and connected. And also, the Intersection is the decision-making section for drivers to select the route according to the geometric structure and operation method. However decision-making section cause to raise car accidents rate because it imposes a heavy burden on drivers. In that reason, many countries such as Europe use the Roundabouts to reduce the numbers of decision making and collision. In Korea, the kinds of method are just introduced and it is using now but there are no exact standards. Hence, this study suggests the process to evaluate and determine the types of Intersection which are based on the traffic flow (congestion) and traffic safety (accidents). Firstly, this study presents the number of accident at each Intersection which is depended on the traffic volume. Secondly, this study calculates and analysis the accident at signalized Intersection, non-signalized Intersection and Roundabout by TSIS-NETSIM program. Thirdly, this study concludes the best suitable Intersection type through the materials which are mentioned before.

The objective of this research is to investigate how implementation of smart factory systems(SFS) effects management accounting(MA). The results based on data collected from 108 Korea small and medium enterprises(SME) confirmed that SFS implementation caused significant MA changes. Estimated regression models revealed that the most important SFS characteristic were the analytical capabilities since it positively influenced MA changes in four dimensions: internal reporting, budgeting, application of modern accounting techniques and MA employee's job. In the segment of budgeting, the quality of implementation of specialized bedgeting software had significant and positive influence. The only negative correlation founded was the one between the uncertainty of business environment and adoption of modern accounting techniques. Results from this study provide that SME should put special focus on implementation of business analytics modules in order to achieve comprehensive benefits in MA prctices.
