An aircraft, its engine and propeller are certified in processes of design, production, and operation respectively. Type Certificate is issued if the aviation authority finds that the design of aircraft, engine, or propeller complies with applicable airworthiness standards and environmental standards. The ICAO(International Civil Aviation Organization) prescribes the international standards and recommended practices of type certification for the contracting states. The FAA(Federal Aviation Administration) and the EASA(European Aviation Safety Agency) established their regulations and procedures applicable to type certification. In this paper, we compared the differences among the ICAO, the FAA, and the EASA regulations, and on this comparison, we proposed the rulemaking items to improve type certification regulations in Korea.

The purpose of this study was to examine the relation between level of income, perceived parental behaviors, and ego-identity of school-aged children. The subjects were 356 children in the 6th grade selected from six elementary schools in Seoul and Keunggi-Do. The subjects were asked to complete the questionnaire on ego-identity and perceived parental behaviors. The data was analyzed by Mean, SD, Cronbach's α, Pearson's correlation and Multiple Regression. The major findings were as follows: 1. The level of income(antecedent variable) was significantly related with perceived parental behavior(mediator) and ego-identity of school-aged children(dependent variable). 2. The effects of level of income on ego-identity of school-aged children became lower after control of the effects of perceived parental behaviors. In other words, perceived parental behaviors partially mediated the effects of level of income on ego-identity of school-aged children.
