본 논문은 군과 경찰 등에서 수행하는 시뮬레이션 사격 훈련 중 스크린 사격과 VR 사격이 혼합된 복합 훈련 환경에서 사용할 수 있는 일체형 시뮬레이션 사격 서비스에 대해 연구하였다. 이 서비스는 스크린과 HMD에 투사되는 목표물에 대해 사격 훈련이 가능하도록 설계한 서비스로 하나의 가상공간에서 사용할 경우 스크린을 이용한 개인 사격 훈련과 VR을 이용한 팀 사격 훈련이 동시에 가능하다. 일체형 시뮬레이션 총기의 총구에 비가시 적외선 레이저 모듈을 장착하여 스크린 사격이 가능하도록 하고, 총열 상단에 HTC Vive Tracker를 장착하여 VR 사격에서 훈련자의 자세 및 위치를 인식하게 한다. 총열 하단에는 사용자의 행동을 제어하는 손잡이 형태의 인터페이스 모듈을 장착한다. 비가시 적외선 레이저 모듈과 인터페이스 모듈에서 발생한 신호는 일체형 시뮬레이션 총기의 총열에 장착한 무선 통신 모듈에 의해 블루투스 방식으로 통합 제어 장치로 전달되어 처리함으로써 혼합 환경에서 사용이 가능하다. 스크린 사격과 VR 사격이 동시에 가능한 혼합 환경에서 시험한 결과 운용이 가능한 것을 확인하였다. 일체형 시뮬레이션 사격 서비스는 기존 사람 중심의 훈련 서비스에서 자동차 또는 함정 등과 같은 조종 훈련 플랫폼과 연동하여 운용할 수 있는 기술 발전이 필요하다.

Currently, the accessibility of households for the visually impaired has increased compared to the past, but there are still many shortcomings in existing methods, and conversely, in the process of changing to a touch screen, there have been more situations that cannot be determined by hand. In this paper, we propose a method to increase the accessibility of blind people to refrigerators, one of the essential furniture, by changing people's action to voice with device linkage and server communication.

Purpose: Adequate public input and participation in environmental health research must be provided to ensure accurate results from studies involving human exposure to potentially hazardous substances. By addressing these ethical issues associated with environmental health research, this study can help reduce risks for individuals participating in studies and whole communities affected by their impactful findings. Research design, data and methodology: The current research should have followed the rule of qualitative textual research, searching and exploring the adequate prior resources such as books and peer-reviewed journal articles so that the current author could screen proper previous works which are acceptable for the content analysis. Results: The current research has figured out four ethical issues to improve environmental health study as follows: (1) Lack of Guidance for Collecting and Utilizing Data Ethically, (2) Insufficient Consideration Is Given to Vulnerable Populations When Conducting Studies, (3) Unclear Standards Exist for Protecting the Privacy Of Participant's Personal Information, and (4) Conducting Socially and Religiously Acceptable Research in Various Communities. Conclusions: This research concludes that future researchers should consider implementing anonymization techniques where possible so that findings are still accessible, but the risk posed by disclosing identifying information remains minimized during the analysis/publication stages.

This study is normal orientation technology of slit coating equipment to improve the quality of curved displays. Currently, the demand for curved displays is increasing significantly due to advantages such as screen immersion or design in various industries. Accordingly, changes in the display coating process are essential. In the curved display coating process, unlike the existing flat coating process, the nozzle must be rotated along the curvature of the curved surface to spray the coating solution. The coating solution must be applied while maintaining a uniform thickness. If the thickness of the coating liquid applied to the target surface is non-uniform, the quality of the product may be degraded such as image quality deterioration and light spreading. This paper presents technology and experimental results for keeping the nozzle of slit coating equipment perpendicular to the curved surface and is expected to contribute to the quality improvement of curved displays.

Purpose - This study aims to examine the role of contract law in mergers and acquisitions (M&A) and to examine whether or not contract law is necessary in M&A. The study also discusses how contract law can be utilized in M&A, as well as some of the problems that arise from the use of contracts in this area. Research design, data, and methodology - To minimize bias and errors, this study used only peer-reviewed articles and book excluding internet news articles, conference papers, and dissertations. For a well-organized screen and selection process, the author conducted the extraction procedure thoroughly to eliminate some duplicated resources. Result: This study indicates that complex deals carry a high risk but also have the potential to yield substantial revenue for stakeholders. Thus, contract law is essential to the success of M&A because it helps to define the (1) terms of the transaction, (2) reduces risk, (3) offers legal safeguards, and ensures that the (4) agreement is enforced. Conclusion - This study concludes that an understanding of contract law is essential to the profitable merging of two businesses. The application of contract law provides a mechanism for enforcing the agreement, which can increase the likelihood that the stipulations of the M&A will be satisfied.

Purpose: The present research encircled on a systematic view of leadership in sports, an area that can be used to boost the skilling of employees. Four specific managerial development tools have been formulated during this research based on relevant materials studied in the previous section. Research design, data and methodology: This research used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards to systematically search for, screen, and synthesize relevant past research on using sports leadership principles for team member development. Results: The findings in this research offer four staff leadership development program ideas that are unique and beneficial for firms looking to foster the development of strong leaders. By deploying sport-based principles and methodology, these approaches can solve the limitations of conventional leadership development programs. This will demonstrate how each plan can help HR managers develop the appropriate strategies for their companies. Conclusions: In sum, this research suggests that by incorporating time-honored principles of sports leadership, these models will provide HR managers with an excellent arsenal of tools for developing a generation of leaders endowed with the skills, mindset, and resilience required to ensure the organization's prosperity under the most adverse conditions.

Optical imaging systems that operate through atmospheric pathways often suffer from image degradation, mainly caused by the distortion of light waves due to turbulence in the atmosphere. Adaptive optics technology can be used to correct the image distortion caused by atmospheric disturbances. However, there are challenges in conducting experiments with strong atmospheric conditions. An optical phase plate (OPP) is a device that can simulate real atmospheric conditions in a lab setting. We suggest a novel two-step process to fabricate an OPP capable of simulating the effects of atmospheric turbulence. The proposed fabrication method simplifies the process by eliminating additional activities such as phase-screen design and phase simulation. This enables an efficient and economical fabrication of the OPP. We conducted our analysis using the statistical fluctuations of the refractive index and applied modal expansion using Kolmogorov's theory. The experiment aims to fabricate an OPP with parameters D/r₀ ≈ 30 and r₀ ≈ 5 cm. The objective is defined with the strong atmospheric conditions. Finally, we have fabricated an OPP that satisfied the desired objectives. The OPP closely simulate turbulence to real atmospheric conditions.

In this study, the function and purpose of the disposal cover, which is an engineering barrier installed to isolate the disposal vault of the near-surface disposal facility for radioactive waste from natural/man-made intrusion, and the design details of the demonstration facility for performance verification were described. The Demonstration facility was designed in a partially divided form to secure the efficiency of measurement while being the same as the actual size of the surface disposal facility to be built in the Intermediate & low-level radioactive waste disposal site of the Korea Radioactive Waste Agency (KORAD). The instruments used for measurement consist of a multi-point thermometer, FDR (Frequency Domain Reflectometry) sensor, inclinometer, acoustic sensor, flow meter, and meteorological observer. It is used as input data for the monitoring system. The 3D monitoring system was composed of 5 layers using the e-government standard framework, and was developed based on 4 components: screen, control module, service module, and DBIO(DataBase Input Output) module, and connected them to system operation. The monitoring system can provide real-time information on physical changes in the demonstration facility through the collection, analysis, storage, and visualization processes.
