The quality of hospital services remains a concern of both the manager and the patient. The study aims to identify factors affecting outpatient satisfaction at private general hospitals in Ho Chi Minh City, establishing a scale for measuring them. Some 450 outpatients who were treated in five top private hospitals in Ho Chi Minh city (HCMC) in 2019 - An Sinh General Hospital, Hoan My General Hospital, Columbia Asia International Hospital, FV Hospital, and Vu Anh International General Hospital - were interviewed directly in the last quarter of 2019 to obtain the information. The SERVPERF model, plus the cost, together with the SPSS software, have been used to process information by Cronbach's alpha analysis, Exploratory Factor analysis, and linear regression analysis. The results show that there are five factors influencing outpatient satisfaction at private general hospitals in HCMC, in which four factors affects positively in the order of decreasing importance: treatment outcome, doctors and nurses' professional capacity, facilities and environment of the hospital, hospital care, and the treatment time factor affects negatively. The results of the study provide private hospital in HCMC managers with a number of suggestions to increase the level of hospital service quality, so that increase outpatients satisfaction.

A new operational concept for the CNS/ATM using the digital data communication technology and satellite navigation system is being implemented globally and the United States is the first country to apply UAT ADS-B system for general aviation. Korea also has plan to build ADS-B system for aeronautical surveillance to monitor low altitude flight of light aircraft and ultra-light flying device and the research to develop UAT ADS-B equipment is being carried out. This paper presents the application method of UAT ADS-B to support test operation with case study of foreign UAT ADS-B operation and survey of domestic environment.

Pilot and flight crew visual performance in general aviation aircraft operating is paramount for safe operation of the aircraft. Pilot compartment view, instrument and cockpit lighting forms an essential aspect of this visual performance, and therefore warrants guidance and standardization. This study introduces acceptable design criteria for pilot compartment view, instrument and cockpit illumination for general aviation aircraft.

조종사의 태도가 의사결정시 작용하는 중요 요인임은 많은 연구들을 통해 알려져 왔으며 특히 미국의 GAMA(General Aviation Manufactuer's Association)와 Transport Canada에서 수행한 의사결정에 관한 연구에서는 조종사 자신들이 자신의 태도를 진단할 수 있는 질문을 제시하였다. 본 연구에서는 이 설문지를 통해 비행교육을 받고 있는 학생들을 세가지 부류로 나누어 태도진단을 실시하고 부류별 그리고 부류간 차이점을 발견하기 위해 통계기법을 이용하였으며, 통계분석을 통해 도출되는 사항들에 대한 대안으로서 의견을 제시하였다.

This paper describes boundary analysis for modeling Aircraft Carrier Sortie Generation System(CVSGS). An aircraft carrier, as a super system, is a warship going into battle by operating a number of aircraft on deck and it should be lay down a definition about aviation operations interacting between aircraft carrier and carrier air wing in small deck area. For this reason this paper models common aviation support system for generating sortie basic unit of carrier aviation operations unlike to general warship and defines boundaries between this system and aircraft carrier and carrier air wing. This paper analysis activities of aircraft carrier and embarked carrier air wing in carrier aviation operations, and analysis and defines boundaries Aircraft Carrier Sortie Generation System(CVSGS) to perform core functions in interacting between aircraft carrier and embarked carrier air wing.

The terrorism threat against aviation industry is increasing after 9/11 incidents. As the way of preventing the future threat, this study is to review current status and make practical suggestions on Incheon International Airport security screening. The Library research method is utilized for this study. Chapter 1 is an introduction part and describes the general instruction. Chapter 2 describes the importance of aviation security and cases of aviation terrorism. Screening history is described in chapter 3 detailing operations and equipment. Status of IIAC(Incheon International Airport Corporation) security screening and prevention measures are described in chapter 4 and chapter 5 describes the final conclusion. In conclusion, if the introduction of state-of-the-art security equipment and modification of inadequate regulations come in first, whatever the threat exists, aviation terrorism can be prevented with the positive prevention efforts.

This study examines the history of Korean aviation industry and presents the investment strategy based on the evidence and the 4th industrial revolution. Looking at the evolution of the Korean aviation industry and its technological development will be a great help to support industrial and technological innovation in the future. The modern aviation industry is divided into stages of development, focusing on maintenance of equipment introduced in advanced countries, localization through license assembly, production of products based on technology, and international joint development. The development of aeronautics technology has been progressing towards a general improvement of economic efficiency, aircraft safety efficiency through environmental-friendliness, unmanned operation, and downsizing. The Korea Aerospace Research Institute has secured key technologies through development of several aircrafts such as Experimental Aircraft Kachi, EXPO Unmanned Airship, Twin-engine Composite Aircraft, Canard Aircraft, Multi-Purpose Stratosphere unmanned-airship, Medium Aerostats, Smart UAV, Surion, EAV-2H, KC-100, and OPV. The development strategy is discussed at the level of the evidence-based investment strategy that is currently being discussed, and so the investment priorities in aircraft is high. Current drone usage and development direction are not only producing parts using 3D printer, but also autonomous flight, communication (IoT, 5G), information processing (big data, machine learning). Therefore, the aviation industry is expected to lead the fourth industrial revolution.

TSA needs to be more transparent with the new passenger screening system and its functioning to build the citizen trust. The system is needed to be not only effective but supported by Congress and the general public. Until this occurs, skepticism will underlie any discussion about its effectiveness in balancing the protection from terrorism with respect to individual liberties. CAPPS II can be a viable system if it is developed appropriately. The objectives of the study are to introduce the security program in the U.S. aviation security policy and to discuss privacy problems when it applies. Korea also needs to study a harmonious plan with the basis of global approach mind in the case of considering the transferring of passenger information from other states for the purpose of security.

The coronavirus infectious disease-19 (COVID-19) pandemic has had a profound impact on the aviation industry. In order to overcome this crisis, airlines have made their efforts in various fields. Therefore, we tried to summarize these efforts of airlines. It is also essential to keep aircraft that have been in landing for a long time in optimal condition. In this paper, we tried to find out about efforts to maintain landing aircraft and maintenance of personnel. Through such constant care, airlines will be able to quickly respond to increasing aviation demand when the infectious disease situation is stabilized in the future. Finally, airlines and passengers must make several efforts to ensure that passengers are free from COVID-19 while traveling by air. These include general precautions to prevent infection, separation of airline personnel and passengers, changes in seat assignments and in-flight services, periodic aircraft disinfection, and prevention of in-flight infections.
