The worldwide improvement of the safety, efficiency and rationality in the field of aircraft operation environment and certificate management of aviation personnel has been proceeded cheerfully as a part of each country's globalization movement. Considering the importance of aviation transportation industry supporting nation's international trading has the competition among the airlines regarded possibly as that among the countries. In order to make Korean Government and Airlines more competitive in this race, the standardization and generalization of aviation regulations are required. On this study, some amendments are recommended to improve regulations and systems for pilot's certification management and operation environment by comparison analysis of regulations of ICAO, FAA and Korean aviation law.

The study proved the fitness between competitive strategy and service operation strategy of service companies. The competitive strategy of a corporation is a major strategy playing the role of bridge linking both corporate strategy and functional strategy. And it is a choice of method how to win competitors in given area. There have been such a specific methodologies for acquiring competitive advantage as Porters competitive strategy, Miles and Snows adaptive strategy, and Life cycle strategy. But, many scholars have pointed that its more important for high corporate performance to determine the competitive strategy of a corporation fitting the external environment and internal structure. So its needed for successful cost-leadership or differentiation strategy to differentiate organizational function, resources, and various organizational factors. But there have been no methodologies or practical guidelines fitting competitive strategy, corporate structure, and external environment in sprite do service corporations growth. So, the study proved the fitness between competitive strategy and service operation structure in Airlines after selecting service structural elements necessary for strategic management.

The number of airline passengers in China has rapidly increased, so understanding the relationship between brand equity of airlines in China and ticket purchase intention of Chinese passengers is important for airline business success in China. Using the structural equation modeling, this study explores the relationships among determinants of brand equity as well as the relationships between brand equity, transition cost, and purchase intention. The major findings are: brand equity of airlines directly influences purchase intention; transition cost directly influences brand equity; and transition cost indirectly influences purchase intention in China. In addition, the results show that marketing strategies using the airline brand can be more effective for certain customer groups, including high income customers, married customers, government servants, and businessmen.

Risk Based Oversight is a way of performing oversight, where planning is driven by the combination of risk profile and safety performance. Risk Based Oversight enables prioritization and allocation of State's safety management resources commensurate with the safety risk profile of each service provider. This paper presents the concept of Risk Based Oversight and applies it to the current Korean aviation safety oversight process. In particular, this study presents a method for generating operating profiles, one of the key concepts of Risk Based Oversight. Operations Specifications of Part 121 Airlines can generate operating profiles. In this study, a practical study was conducted to generate the operating profile and scoped DCTs using Part 121 Airlines's Operations Specifications.

This research aims to investigate the relationship between safety climate and safety perception and safety behavior. Safety perception of the relationship is considered to have a mediating effect. Previous literature has tended to regard safety perception as an independent variable at the same level as the safety climate, which can be said to depend on behavioralism to approach the causal relationship to an one-way perspective. The survey was administrated through full- service carries in Korea such as Korean Air and Asiana Airlines, and low-cost carriers such as JeJu air, Jin air, and Air Pusan. It can identify a mediator of safety perception between safety climate and safety behavior. There are significant indirect effects of each value, which means mediators values of safety perception of safety climate variables and safety behavior. The study highlights that airlines should focus on the importance of their psychological aspects to strengthen the safety behavior of flight attendants and the value of organizational efforts to mature safety perceptions, suggesting some implications of theoretical and practical aspects.

There has been a lot of researches on the major motivation of consumer's choice for airlines. Due to the competition in airline industries, most of airlines offer a various level of benefits to customers such as a frequent traveller bonus, a schedule, services in flight including a meal and an entertainment program, a discounted fare and an intangible part of personal service. However, it is very difficult to measure the performance of the customers' benefit and to identify the weight of each factor being considered on the airline choice. In this paper, we focus on the airline choice process for the business travellers. The AHP is applied to evaluate the factors reflecting the business travellers' choice for airlines. This study will be useful to build a marketing plan for the business traveller's market.

Influence of Ag nanoparticles on optical and photovoltaic properties of, silicon substrates, silicon solar cells and glass have been investigated. Silver nanoparticles have been fabricated by evaporation of thin Ag layers followed by the thermal annealing. The surface plasmon resonance peak was observed in the absorbance spectrum at 470 nm of glass with deposited silver nanoparticles. It is demonstrated that deposition of silver nanoparticles on silicon substrates was accompanied with a significant decrease in reflectance at the wavelength 360-1100 nm and increase of the absorption at wavelengths close to the band gap for Si substrates. We studied influence of Ag nanoparticles on photovoltaic characteristics of silicon solar cells without and with common use antireflection coating (ARC). It is shown that silver nanoparticles deposited onto the front surface of the solar cells without ARC led to increase in the photocurrent density by 39% comparing to cells without Ag nanoparticles. Contrary to this, solar cells with Ag nanoparticles deposited on front surface with ARC discovered decrease in photocurrent density. The improved performance of investigated cells was attributed to Ag-plasmonic excitations that reduce the reflectance from the silicon surface and ultimately leads to the enhanced light absorption in the cell. This study showed possibility of application of Ag nanoparticles for the improvement of the conversion efficiency of waferbased silicon solar cells instead of usual ARC.

In this study, what effects corporate culture of airlines' flight attendants has on job satisfaction was analyzed and the following results were derived. First, it showed that flight attendants of airlines feel job satisfaction with the ability of handling works by themselves before supervisors order something, with the faith of supervisors that subordinates will be able to work well, and with being able to talk about difficulties of the company open-minded. Second, flight attendants inairlines showed different levels of recognition about corporate culture based on age, married or not, position and how long they have worked in the company. Especially, it showed a big difference by their positions. Third, looking into the effect demographical characters have on job satisfaction, it indicated that the higher the positions were, the higher job satisfaction was, and especially, compared that job satisfaction of flight attendants having 4-7 years' careers is low, that of the flight attendantsmore than 8 years is high.
