Currently, in Korea, to obtain a jet type rating, you must receive training on a small business jet model. The reason is because of the law in the Aviation Safety Act Enforcement Rules 『Appendix 4』 that states, "You must receive at least 2 hours of flight training." In the end, it is acquiring type rating as a small business jet aircraft with relatively low operating costs. The qualifications acquired in this way are different from those for aircraft operated by airlines. However, if you have an initial jet type rating, you can acquire an airline aircraft qualification just by training on a simulator, so airlines want you to have at least a small-jet type rating. However, in the United States and Australia, there is a system in place to acquire initial jet type rating through simulator training without actual flight training.

An airman licensing system is central to the establishment and management of a state's airman licensing which gives official privileges to a person to perform specific activities by evaluating applicant's knowledge and proficiency. In recent decades, the level of the domestic aviation industry continues to leap forward and state's airman licensing system has also been advanced. However, accidents caused by pilot human errors are still occurring. In particular, the pilot occupations require a lot of experience and knowledge and the student pilots receiving the initial flight training have formed their own flight habits based on knowledge, skill, training methods, procedures, etc learned from the flight instructor. This paper discusses possible ways on the improvement for the domestic flight instructor rating by analyzing domestic and international rules and procedures for a flight instructor rating.

The qualification test for robot technology is developed to provide a standard for evaluating professional knowledge on robotics and is currently under consideration to be one of the government-approved qualification tests. This test has a level to which elementary school students can apply, but is not recognized by most teachers in elementary school compared to so called "after school robot classes." This paper addresses and analyzes the current status of the test, in particular, the qualification standards, organizing committee, examples of problems used in the test, etc. It is suggested that the level of difficulty and contents covered should be properly adjusted. Moreover, it is essential to provide well organized supplementary material for students and wide range of contents on which a solid standard for evaluating robot technologies can be developed.

The Earned Income Tax Credit (EITC) is a policy that supports low-income households financially as well as provides an economic incentive to participate in the labor market. Thus, estimating the causal effect of the policy on the labor force participation rate of low-income households is critical for the policy evaluation. In this paper, we exploit the variation in the eligibility to the EITC and the size of the benefit over several reforms of the EITC in South Korea since 2008 and estimate the impact on the participation in the labor market. Using data from four major household surveys, we find that the results are mixed; in some samples and specifications, we find that the effect is positive and statistically significant, while it is insignificant in others. The estimated effect is more likely to be positive and significant when we restrict the sample to the period before 2014. It is an important topic of future research whether the EITC's effect gets weaker because it is extended to cover the self-employed and beneficiaries of the National Basic Livelihood Security.

Recently, the aviation leisure business has been legislated, and related industries have become active base with increasing the light sports aircraft within the legislation system. However, in the light sports aircraft safety problem, it is often mentioned that the flight is in violation of the regulations, the lack of safety consciousness of the operator and lack of ability, and the personal operators have a risk of accident of light aircraft such as insufficient safety management and poor maintenance. At present, the maintenance of light sports aircraft is carried out by the A & P mechanic in accordance with the relevant laws and regulations, but it is difficult to say that it is equipped with qualification and expertise. It is not a legal issue to undertake light sports aircraft maintenance work on the regulation system. However, the problem of reliability and appropriateness is constantly being raised because airplanes, light sports aircraft, and ultra-light vehicle are classified and serviced in a legal method. Although legal and institutional frameworks for light sports aircraft are separated, much of it is stipulated in the aviation law provisions. Light sports aircraft maintenance work also follows the current aircraft maintenance system. In the United States, Europe, and Australia where General Aviation developed, legal and institutional devices related to maintenance of light aircraft were introduced, and specialized maintenance tasks are covered in the light aircraft mechanics system. As a result of analysis of domestic and foreign laws and regulations, it is necessary to introduce the qualification system for maintenance of light aircraft. In advanced aviation countries such as the United States, Europe, and Australia, a light sports aircraft repairman system is installed to perform safety management. This is to cope with changes in the operating environment of the new light sports aircraft. This study does not suggest the need for a light aircraft repairman system. From the viewpoint of the legal system, the examination of the relevant laws and regulations revealed that the supplementary part of the system is necessary. It is also require that the necessity of introduction is raised in comparison with overseas cases. Based on these results, it is necessary to introduce the system into the light aircraft repairman system, and suggestions for how to improve it are suggested.
