The Patient Safety Act was enacted on July 26, 2016. Patient safety law is a method to prevent harm by collecting and accumulating various errors through the reporting system. Therefore, in order for this law to be successfully implemented, it is necessary to vitalize 'the autonomous reporting and reporting learning system of patient safety accidents'. And In order for this system to be activated, a large amount of reporting data accumulation is a prerequisite. Nevertheless, there were only two reports in about 17 months. In this paper, I will criticize the validity of the current autonomous reporting system and the two proposed amendments, I would like to propose the introduction of a partial obligation reporting system.

Purpose: This study aims to determine the status of dental technician's continuing education and licensing reporting and provide basic data that can aid in improving the operation of progressive continuing education and licensing reporting and development programs. Methods: This study included dental technicians nationwide who attended the 2023 Korea Dental Technology Expo & Scientific Conference and responded to an online survey from July 21 to July 23, 2023. In total, 180 copies were analyzed. The reliability of satisfaction with continuing education demonstrated a Cronbach's α of 0.924. IBM SPSS Statistics version 21.0 (IBM) was used to statistically analyze the collected data. Results: Satisfaction with continuing education for dental technicians was 2.78, 2.81, 3.21, 2.96, and 2.87 for the number of lectures offered, composition of major fields, lecture content, instructor level, and overall satisfaction, respectively. The average satisfaction with continuing education was 2.93, which was lower than the average (3 points). The investigation revealed that overall improvement was required. Conclusion: Measures for those who have not completed continuing education must be implemented within the government's legal influence by actively using the license reporting system. Strengthening verification of completion of continuing education, improving autonomous disciplinary rights, diversifying the content and learning methods of continuing education, linking with the license reporting system, improving institutional postevaluation, and introducing related policies should be conducted when opening a dental laboratory.

To monitor the world's oceans and understand the role of the oceans for climate change, an Array for Real-time Geostrophic Oceanography (ARGO) program has been carried out since year 2000. Autonomous profiling floats of about 820 are reporting the vertical temperature, salinity, and pressure profiles of the upper 2000 m underwater at regular time intervals. Meteorological Research Institute (METRI) of Korea Meteorological Administration (KMA) launched 45 floats at the East Sea and the western Pacific to understand characteristics of water properties and develop the global ocean observation system as a part of international cooperation project. In this study, we introduce ARGO program, METRI-ARGO and the features of APEX float itself and their data formats. We also describe the significant points to be considered for using ARGO data.

항공산업의 초창기에는 항공기 안전사고의 대부분이 기술결함으로 인하여 발생하였다. 그러나 항공기술의 발달로 인한 첨단화, 정밀화되면서 기술결함에 의한 사고는 대폭 감소하였지만 인적요인에 의한 사고는 일정한 수준 감소 이후 꾸준하게 유지하고 있다. ICAO따르면 인적요인의 70~80%가 재발 가능성이 존재하며 독자적인 원인이 아닌 위험요소의 복합적작용으로 발생한다고 기술하고 있다. 이를 방지하기 ICAO에서는 항공안전을 위협하는 사고(ACCIDENTS), 준사고(Serious INCIDENTS), 항공안전장애(HINDRANCES)등의 데이터를 수집, 공유, 분석을 통해 항공안전 위해요소를 사전에 제거, 차단할 수 있는 사전예방 시스템의 수립을 권고하고 있으며 이를 위해 국제사회를 중심으로 의무보고제도, 자율보고제도 등이 활발하게 운영되고 있다. 그러나 국내의 경우 운영시스템의 체계화 및 정부, 관련부처의 노력에도 불구하고 일부보고제도만이 정착되어있고 자율보고제도는 사회적 환경, 문화적 요건의 차이 등으로 인하여 활발하게 운영되지 못하고 있다. 따라서 국내 외 안전자율보고제도의 동향을 바탕으로 해당제도의 효율적인 정착 방안을 모색할 필요가 있을 것이다.

To ensure the safety of Advanced Driver Assistance Systems (ADAS) or autonomous vehicles, it is important to recognize the vehicle position, and specifically, the increased accuracy of the lateral position of the vehicle is required. In recent years, the quality of GPS signals has improved a lot and the price has decreased significantly, but extreme urban environments such as tunnels still pose a critical challenge. In this study, we proposed stable and precise lane recognition and tracking methods to solve these two issues via fusion of AVM images and vehicle sensor data using an extended Kalman filter. In addition, the vehicle's lateral position recognition and the abnormal state of RTK GPS were determined using this approach. The proposed method was validated via actual vehicle experiments in urban areas reporting multipath and signal disconnections.

Not only emotions affect physical sensations, but they also have an impact on physical movements. The responses to emotions vary depending on the type of emotional stimuli. However, research on the effects of emotional stimuli on the activation of bodily movements has not been rigorously examined, and these effects have not been investigated in Autonomous Emotion Recognition (AER) systems. In this study, we aimed to compare the emotional responses of 20 participants to three types of emotional stimuli (words, pictures, and videos) and investigate their activation or deactivation for the AER system. Our dependent measures included emotional responses, computer-based self-reporting methods, and bodily movements recorded using motion capture devices. The results suggested that video stimuli elicited higher levels of emotional movement, and emotional movement patterns were similar across different types of emotional stimuli for happiness, sadness, anger, and neutrality. Additionally, the findings indicated that bodily changes observed during video stimuli had the highest classification accuracy. These findings have implications for future research on the bodily changes elicited by emotional stimuli.

The monetary penalties system inherently has efficiency as DNA. In the event that administrative measures to recover unfair profits from businesses that violate the law, deprive business licenses, or order to suspend business, infringe the interests of ordinary consumers, a system that can achieve the same effect through financial sanctions. It is a monetary penalties. In addition, it is convenient for the government because it takes effect only by the administrative agency's unilateral imposition order compared to the trial process, which takes a long time and huge cost to prove the illegality. However, it is questionable whether procedural legitimacy is well established in Korea's aviation monetary penalties. Compared to foreign legislation, Korea's aviation monetary penalties system need to be improved. This paper was for the purpose of studying the improvement direction of the monetary penalties system disposed of in the Korean aviation field. This study suggests the direction by examining the US system, which is an aviation advanced country, in the aviation safety area. The research was conducted with the intention of exploring the direction as follows: First, the characteristics of the Federal Aviation Administration (FAA) aviation administrative sanctions and the US aviation penalty system will be outlined. Furthermore, with the recent paradigm shift in aviation safety management, this paper tried to look at new trends that focus on autonomous reporting of aviation safety as a proactive and preventive measure in conventional post-airline accident management administration, focusing on various systems including ASAP. This article also reviewed the formal process for imposing monetary penalties adopted by the FAA. Based on the above review, this paper also looked at ways to improve the reporting system for aviation safety in Korea.

Telemetry, satellite event and error information are used to check the satellite status in ground station. Different from telemetry which only informs the parameter value, event and error gives explicit information of a certain operation or status. Event also contains ground action information because every command execution is logged as event. Currently, those information is gathered and applied only for monitoring of the satellite. However, the load of the operation is getting grown because of the excessively increased information of the satellite with the number of satellite increasement. Also, the process of reporting problem to developer (or an expert) induce time delay for satellites fault management. In this paper, we propose a satellite operation assistant system which collects event sequence and stores in different group by its feature, and then recommends or executes an appropriate action for the identified abnormal state. This system is applicable to on board system for resolving LEO-satellite autonomous fault situation since is has limited contact time.

In this paper, we describe certificate policy and characteristics in cooperation condition with Cooperative intelligent transport system and autonomous driving vehicle. Among the authentication functions of the vehicle, there is a pseudonym authentication function. This pseudonymity is provided for the purpose of protecting the privacy of information that identifies the vehicle driver, passenger or vehicle. Therefore, the purpose of the pseudonym certificate is to be used for reporting on BSM authentication or misbehavior. However, this pseudonym certificate is used in the OBE of the vehicle and does not have a cryptographic key. In this paper, we consider a method for managing a pseudonym authentication function, which is a key feature of the pseudonym certificate, such as location privacy protection, pseudonym function, disposition of linkage value or CRL, request shuffling processing by registry, butterfly key processing, The authentication policy and its characteristics are examined in detail. In connection with the management of pseudonymes of the vehicle, the attacker must record the BSM transmission and trace the driver or vehicle. In this respect, the results of this study are contributing.

This study aims to analyze safety reports received through the recently added SMS safety self-report in the Air Force's "integrated air control management" system, identify hazards, present improvements by region (base), and lay the foundation for future data-based safety management. To identify risk factors, it was first classified by base based on data classified into 16 groups in the autonomous reporting system, and second classified in detail based on the type and description. Risk factors were analyzed for the most reported control cooperation (306) items, and improvements were derived by dividing risk factors into information sharing, regulations, procedures, education, training, and equipment items based on the analysis results. It was confirmed that risk factors and specific improvements vary by base (12), which is important data that can present statistical analysis and the direction of safety management in the flight control field by base (region). In addition, since there is no data-based risk factor analysis study for each specific base (region), it can be used in the future as basic research data for data-oriented safety management.
