A trajectory-based scheduling system is proposed for air traffic management using next generation aviation data communication link. Based on the service concept of 4-dimensional trajectory data link (4DTRAD) using air traffic serveices (ATS) datalink Baseline 2, a procedure for trajectory-based operation of an en-route flight is established and described in detail. To mitigate air traffic controllers' workload which might be caused by various and complicated data utilization, a prototype of the scheduling system, which predicts the aircraft trajectory based on the flight intents received by air traffic service system and provides advisory information for air traffic control, was developed. The simulation environment for trajectory based operation was built to validate the scheduling functionality of the prototype.

Frequent false positives alarm from the Intelligent Selective Control System have raised significant concerns. These persistent issues have led to declines in operational efficiency and market credibility among agents. Developing a new model or replacing the existing one to mitigate false positives alarm entails substantial opportunity costs; hence, improving the quality of the training dataset is pragmatic. However, smaller organizations face challenges with inadequate capabilities in dataset collection and refinement. This paper proposes an automatic human pose data collection system centered around a human pose estimation model, utilizing camera-based sensor fusion techniques and edge devices. The system facilitates the direct collection and real-time processing of field data at the network periphery, distributing the computational load that typically centralizes. Additionally, by directly labeling field data, it aids in constructing new training datasets.

Since Alarm Monitoring Service was introduced in Korea in 1981, the market has been increasing and is expected to increase continually. Some factors such as the increase of social security need and the change of safety consciousness, increase of persons who live alone could be affected positively on Alarm Monitoring Service industry. As Alarm Monitoring Service come into wide use, the understanding of electronic security service is spread and consumer's demand is difficult, so consideration about new developmental plan is need to respond to the change actively. Electronic security system is consist of various kinds of element, so every element could do their role equally. Alarm Monitoring Service should satisfy consumer's various needs because it is not necessary commodity, also electronic security device could be easily operated and it's appearance has to have a good design. To solve the false alarm problem, detection sensor's improvement should be considered preferentially and development of new type of sensor that operate dissimilarly to replace former sensor is needed. On the other hand, to settle the matter that occurred by response time, security company could explain the limit on Alarm Monitoring System to consumer honestly and ask for an understanding. If consumer could be joined into security activity by security agent's explanation, better security service would be provided with mutual confidence. To save response time the consideration on the introduction of GIS(Global Information System) is needed rather than GPS(Global Positioning System). Although training program for security agents is important, several benefits for security agents should be considered together. The development of new business model is required for preparation against market stagnation and the development of new commodity to secure consumer for housing service rather than commercial facility service. for the purpose of those, new commodity related to home-network system and video surveillance system could be considered, also new added service with network between security company and consumer for a basis is to be considered.

The role of admissions officers in universities is to evaluate applicants from a comprehensive perspective on the basis of diverse bases and materials for evaluation that include not only quantitative, but also qualitative information about applicants. Therefore, the crucial key to ensuring the success of the admissions officer system is to ensure the fairness of admission-related decisions and the integrity of individual admissions officers by urging them to render impartial evaluations based on professionalism and avoidance of bias. This study selected the major realm of the ethical education for admission officers on the basis or experts' opinions, and documentary research, and tried to secure the validity of the composed educational contents through the in-depth interviews and discussions with the incumbent admissions officers. The program must handle subjects that are intimately related to the actual experience of many admissions officers, and must be capable of inducing voluntary compliance from the officers. Therefore, the program suggested by this study focuses on three core areas of ethics: that is, 'interaction with society,' 'ethics and responsibilities involved in admission,' and 'legal obligations and roles of admissions officers.' To this end, it provides twelve sub-topics and learning materials. Providing this kind of ethical education programs for admissions officers will help not only to enhance the professionalism and ethical commitments of admissions officers, but also broadly to establish a fairer and more reliable admissions officer system.

In the former aviation law, only the Ministry of Land, Infrastructure and Transport has to provide air traffic services, In the case of providing aviation transportation service from civilian, such as aviation special education institution, private airfield installer, it was possible to carry out only by receiving a private contract from the government. But at the time of private consignment, the fact that the government has to bear the cost through the contract act. It is pointed out that it is a factor that hinders efficiency in the operation sector. Accordingly, in Article 85 of the Aviation Safety Act, which was enforced in March 2017, legal grounds were established to provide air traffic services excluding the Ministry of Land, Infrastructure and Transport. At the same time, we have introduced the air traffic services operating certification system, which enables the air traffic services to meet the requirements set by the Ministry of Land, Infrastructure and Transport in order to secure the safety of air traffic. In this study, we examine the major issues and problems of the small private control tower operated by the private institute in Korea. The effect of introduction of the air traffic services operating certification system which can introduce all the institutions which do not belong to the control agency in the former aviation law into the institutional system and the operation plan were examined.

A regular aperture occurs between persons controlled and a person governing the society according to national formation and development. A ruler is subdivided into a king, the President, or the highest controller who can feel the uncertainty of ruler's position. To protect those people, it is called guard that used all possible means and ways to protect those people or remove the danger. An opening of guard was related to enhancement of royal authority or centralism. Firstly a military organization had acted for this, but the organization gradually became independent according to it's subdivision and systematization. During the period of the Three States and Unified Silla, the guard was needed new management system by enhancement of royal authority, expansion of the territory, and establishment of centralism. The new management system that organized the group of vassal and Siweebu take charge of guarding the king or serving as private soldiers. In the end of Silla, as a wide range of reformation of government organization, the organization of vassal like Jungsasung and Sunkyosung that developed as not only guard the king and prince but also hold the business writing.

선박에서 AIS 탑재가 확대는 해상에서의 전산 시스템 기술 발전에 큰 영향을 미치고 있다. AIS는 VTS가 선박의 식별, 트랙킹, 모니터링과 같은 일반적으로 알려진 기능을 제공하는 것뿐만 아니라 해상 교통 연구, 통계 분석, 학술 연구에 유용한 실시간 정보를 제공하기도 한다. 그러나 AIS 관측 자료의 신속한 축적은 이루어지고 있지만 VTS 플랫폼 측면에서 선박 위치 자료를 수집하고 분석하는데 한계가 있다. 이러한 관점에서 본 연구는 데이터 마이닝 기술과 GIS기술을 적용하여 AIS 자료를 분석하고자 한다. 이것은 해상 교통 관리 분야에 GIS 분석, 데이터베이스 관리 체계, 데이터 웨어하우징, 데이터 마이닝과 같은 잠재된 가치 정보를 도출하는 기술과 통합하는 시도이다. 현재 몇가지 제약사항이 있지만, 향후 VTS 관제 업무에 유용한 자원을 제공하는 새로운 방안이 될 것이다.
