  • Objective: This study aims to characterize airborne radon and thoron levels ($Bq/m^3$) generated from working environments in three subway stations in Seoul. Method: A radon and thoron detector (EQF3220) was used to monitor real-time airborne radon and thoron levels ($Bq/m^3$) and their daughters ($Bq/m^3$) every two hours. They were monitored not only in the driver's cabin of seven circulation lines, but also three offices, platforms, and water pump reservoirs in the three stations. Results: The average levels of radon and thoron were $67.9Bq/m^3$ (range; $7.2-619.4Bq/m^3$) and $44.4Bq/m^3$ (range; $4.3-819.2Bq/m^3$), respectively. Notably, higher than legal airborne radon levels ($600Bq/m^3$) were frequently monitored in the driver's cabin of seven circulation lines. Airborne radon levels monitored in the platforms and administrative offices were found to be over $100Bq/m^3$. The average equilibrium factors (F) were 0.12 and 0.06, respectively. The percentages detected were found to be 84.9 for radon and 72.4 for thoron, respectively. Conclusions: Significant airborne radon and thoron levels were frequently found to be generated in subway facilities including water reservoirs, platforms and driver's cabins. Further study is necessary to thoroughly investigate airborne radon and thoron in all subway stations and to devise proper measures.

  • Air passengers may be compensated for damages based on the above agreement when the passenger suffers an accident to the extent that they are recognized as an accident under Article 17 of the Montreal Convention in 1999. If a flight or cabin crew and passengers both undergo an accident, passengers are subjected to compensation under the Montreal Convention however flight cabin crews will be compensated by the Labor Law, which is the governing law in the labor contract with the airline. The flight or cabin crew boarding the aircraft work is on a work contract, not a passenger transport contract. Therefore, if the flight or cabin crew on the aircraft is injured due to an accident, and the air carrier is liable for default due to a labor contract, the Labor Law, workers or survivors claim damages due to illegal acts against the employer. In which case, civil law will apply. In this regard, if a Chinese cabin crew working for a Chinese airline dies due to an accident in the Republic of Korea, whether the family of the deceased claims damages against the Chinese airline or not has international court jurisdiction in the Republic of Korea, which is the place of tort. We examined whether it is the law of the Republic of Korea or whether it's the Chinese law, the law applicable to the work contract, is applied. Also, Seoul District Court 1995.5.18. The sentence 94A 14144 was found that if the injured crew during the flight work was not satisfied with the insurance compensation under the Labor Standards Act and the Industrial Accident Compensation Insurance Act, he could claime to damage under the civil law against an air carrier or third parties responsible for the accident. This law case shows that you can claim a civil damage as a cause. In case of death due to an existing illness while on the way to work, the Korea Workers'Compensation and Welfare Service did not recognize the death of the deceased as an occupational accident, and the trial was canceled by the parents of the deceased for the survivor's benefit and funeral expenses. (Seoul Administrative Court 2017.8. 31. Although the sentence was judged as an occupational disaster in 2016, the 2016 8816 Decision), it was defeated in the appeals court (Seoul High Court 2018.7.19.Sentence 2017 No. 74186) and I criticized the judgment of the appeal by analyzing the deceased's disease and related the cause of it to workload. Sometimes, a flight or cabin crew is on board not for the flight duty such as transferring to another flight or returning to the home base or lay-over place after their scheduled flight, this is called "Deadheading". If the crew who is not considered the same as a passenger, but is not on duty, is injured in an accident, does the crew claim compensation for damages under the labor contract or whether the Montreal Convention is applied to the passenger. In conjunction with the discussion, there was a similar case, In re Mexico City Aircrash of October 31, 1979, 708 F.2d 400 (9th Cir. 1983), Demanes v. United Airlines, 348 F.Supp. 13 (C.D.Cal. 1972), Sulewski v. Federal Express Corp., 749 F.Supp. 506 (S.D.N.Y. 1990) and reviewed by the European Court of Justice (CJEU) at Wucher Helicopter GmbH and Euro-Aviation Versicherungs AG v. After examining several acts in several countries it's undeniably crucial to clearly understand the definition of "passenger" as stated in the Fridolin Santer case.

  • To meet the demand increasing passengers in railway vehicles, railway transportation service companies are increasing the numbers of cars per train-set. Two solutions, Variable train-set formations and Multiple train-set operation, are common way to increase the transportation capability. These kind of long distance train-set can effect train-set command and control system, and sometimes the digital signals using train line from master cabin can not reach to the systems located the other extremity slave car. This is so called Voltage Drop. This phenomenon is originated from the electrical power consumption and electrical cable resistance, and cause to the equipments or cars located end of the electrical cable way, malfunction or abnormal operations. This voltage drop happens not only in train lines but also Battery Power Lines. The purpose of this investigation is to design high reliability railway vehicles by clarifying the possibility of happening these events case by case, by analyzing the reasons, and finally by finding the best solutions.

  • This research aims to analyze the importance-performance among airline selection attributes using foreign tourists. For this purpose, data were collected from Japanese and Chinese tourists to Korea. Of the various airline selection attributes, four factors were deduced that includes: transport service, accompany service, cabin service and basic service using exploratory factor analysis. This study estimated how important airline selection attributes are and how much are they performed. Also, this study analyzed the ranking among each selection attributes using T-test. The importance-performance analysis showed 'Concentrate Here' in quadrant I, 'Keep up the Good Work' in quadrant II, 'Low Priority' in quadrant III and 'Possible Overkill' in quadrant IV. Quadrant I specifically showed low performance in terms of the following specific attributes: communicative convenience, flight attendant's friendliness, seating preference. As these attributes are deemed significant, airline managers should focus along these areas.
