The study was carried out to establish buffer zone for the protection of the non-target organisms by aerial pesticide application. The two pesticide combination of 3-way tank-mixing of three pesticides for aerial application, ferimzone tricyclazole SC + BPMC EC + validamycin-A SL and hexaconzole EC + isoprothiolane EC+phenthoate EC were selected for the simultaneous control of key pests on paddy rice as blast, sheath blight, brown planthopper and moth. Aquatic organisms including killifish and loach in the paddy field and nearby water reservoirs were not affected by aerial application of the pesticides. However, all the water flea were killed, when they were exposed 10 m from the aerially sprayed site, while the water flea exposed in 30 m away from the site were not affected. Honeybees within 50 m in the wind direction and 20 m in the opposite wind direction showed a mortality of $7{\sim}100%$. Residues concentration of the pesticides in paddy water were not detectable level after six days from aerial application. Drifting distance of aerially sprayed droplet from the target area was within 30 m in the wind direction and 20 m in the opposite direction. Consequently, it was the buffer zones in the aerial pesticides application for the protection of the non-target organisms should be at least 50 m for aquatic organisms and 100 m for honeybees.

Demand for UAM (Urban Air Mobility) aircraft is rapidly increasing in countries around the world due to the problem of traffic congestion in urban areas. Through research and development, various e-VTOL aircraft concepts are being prepared for commercialization, for which airworthiness certification is required, since it is a manned transportation mode for people to board. Factors that pose a fatal threat to the safe operation of UAM aircraft include lightning strikes that can cause damage to structures and disturb the navigation system, as well as icing that impairs flight stability. Since the current UAM aircraft-related lightning and icing certification technology development is insufficient, there is need to develop appropriate airworthiness certification guidelines. In this study, after analyzing the laws and regulations related to aircraft by the FAA and the EASA, we tried to incorporate the lightning and icing certification guidelines for the UAM aircraft. We also analyzed the effects of lightning and icing on UAM aircraft using computational simulation, and presented the basis for establishing practical guidelines for the certification of UAM aircraft to be adopted in the future.

Commerce enriches human life enriched and within commerce, transportation of cargo is arguably the most important in business transactions. Traditionally, marine transport has been major commercial transaction, but carriage cargo by air is on the increase. While the fare for freight in comparison with that of ocean is higher, air freight has many benefits that justify the higher shipping fee; lower insurance premium, packing charges, inventory control, cost management and especially speed. Therefore, air freight transport is accumulating gradually. An air waybill(AWB) is needed in the air transport flow. It is a nonnegotiable security, so the holder cannot transfer of a right to a third party. Some scholars suggest that a negotiable AWB is needed. However, it seems nearly impossible to do so; an e-AWB use shows a gain in numbers, even if it has not met expectations. Going forward, it would appear reasonable to conduct a follow-up study on the utility and legal problem for e-AWB. After sending goods, the consignor has the right of disposition of cargo in some cases, and more research is necessary, because it is related to change of ownership and a trade settlement. According to WATS (World Airlines Transport Statistics), the Korean Air took third place in international freight in 2014, and fifth in total, domestic and international to great acclaim. However, there is a lack of research supporting the business showing. It is hope that more studies on e-AWB, stoppage in transit, and a risk of outstanding amount, etc. connect to develop Korean air freight industry.

본 논문에서는 카페테리아 복리후생의 기본개념의 고찰과 함께 국내 및 국외에서 활용되고 있는 카페테리아 플랜에 대한 사례연구를 통해 A항공사(航空社)를 중심으로 새로운 종업원 복리후생제도 도입을 제시하고자 한다. 복리후생제도 도입방안은 다음과 같다. 첫째, 선택적 복리후생제도에 대한 종업원들의 공감대를 형성하는 것이다. 항공사는 대체로 노동조합이 잘 발달되어 있는 편이고 종업원들의 학력수준도 높은 편이다. 따라서 사내교육 등을 통하거나 노조 설명회를 통하여 전반적인 사회변화에 따른 다양한 선택적 복리후생제도의 효율성, 종업원 니즈에 대한 충족도의 우수성, 저가항공사의 난립에 따른 필연적 M&A 등이 발생할 경우를 대비하여 필요하다는 점, 종업들의 원가에 대한 이해(cost contiousness)가 높아질 수 있다는 점, 등에 대해 알리고 이해를 시킬 필요가 있다. 둘째, 기존에 일률적으로 제공되고 있는 우대탑승제도는 종업원마다 매년 일정한 한도가 부여되지만 티켓을 소비하는 횟수는 각각 다르다. 또한 항공업의 특성상 성수기로 인해 원하는 시간에 원하는 곳을 갈 수 없다는 큰 문제점이 발생하고 곧 니즈 욕구에 대한 불만족으로 직결 한다. 우대탑승 제도에 부여된 항공 티켓 지원은 비수기나 여유 있는 좌석상황에 따라 소비할 수 있기 때문에 종업원의 만족도는 높지 않게 나타난다. 따라서 종업원의 수혜수준을 종업원이 스스로 선택할 수 있게 함으로써, 사원 스스로의 니즈에 맞게 복리후생 계획을 세울 수 있게 하는 카페테리아플랜 즉 선택적 복리후생제도의 도입의 검토가 필요하다. 이런 선택적 복리후생제도는 종업원의 측면에서 좀 더 자신의 상황과 요구에 부합하는 복리후생을 수혜함에 따라 만족도가 증가하고, 스스로 복리후생을 선택함으로써 동기를 부여하는 측면의 의의가 있다. 그러나 현 기업의 능력과 종업원 의식에 대한 정확한 분석 및 이해가 없는 외부 성공사례의 도입은 지금까지 우리나라 많은 기업들의 경영기법 도입사례와 같이 일과성으로 끝나는 위험성도 크다. 따라서 보다 깊은 자기 성찰을 통한 제도의 수용과 이를 부분적으로 개선 및 보완하여 적용할 줄 아는 지혜가 무엇보다도 우선되어야 할 것이다.

To develop a crisis management for aviation safety, this study has defined crisis management includes risk management which is eliminates or lowers risks prior to accidents and emergency response after the accidents. This study takes a look at different kinds of crisis managements, risk managements and statistical methods of other nations and fields in order to develop a risk management model. Through surveys which have 102 risk factors that include air traffic control, maintenance and airport sectors, the weight of each risk factor was calculated and the probability was divided to develop a model for risk management. The risk management model of this study is conducted using four steps (risk management plan, risk factor identification, weight and probability analysis, decision making) and 4 standards of weight along with 5 standards of probability This study takes a look at Predictions through a quantitative method using a risk index for the risk management model An effective risk management model should have a wide and continuous collection of data and adopt various methods using this model. The crisis management could not be very effective only using a pre-active risk management. So it should also be conducted by using a pro-active response system to protect additional damage and to prevent accidents of the same nature. From the results, the most important points were the establishment of command and control accountabilities, and cooperation of related organizations.

The monetary penalties system inherently has efficiency as DNA. In the event that administrative measures to recover unfair profits from businesses that violate the law, deprive business licenses, or order to suspend business, infringe the interests of ordinary consumers, a system that can achieve the same effect through financial sanctions. It is a monetary penalties. In addition, it is convenient for the government because it takes effect only by the administrative agency's unilateral imposition order compared to the trial process, which takes a long time and huge cost to prove the illegality. However, it is questionable whether procedural legitimacy is well established in Korea's aviation monetary penalties. Compared to foreign legislation, Korea's aviation monetary penalties system need to be improved. This paper was for the purpose of studying the improvement direction of the monetary penalties system disposed of in the Korean aviation field. This study suggests the direction by examining the US system, which is an aviation advanced country, in the aviation safety area. The research was conducted with the intention of exploring the direction as follows: First, the characteristics of the Federal Aviation Administration (FAA) aviation administrative sanctions and the US aviation penalty system will be outlined. Furthermore, with the recent paradigm shift in aviation safety management, this paper tried to look at new trends that focus on autonomous reporting of aviation safety as a proactive and preventive measure in conventional post-airline accident management administration, focusing on various systems including ASAP. This article also reviewed the formal process for imposing monetary penalties adopted by the FAA. Based on the above review, this paper also looked at ways to improve the reporting system for aviation safety in Korea.
