Until Montreal Convention was established in 1999, the Warsaw System is undoubtedly accepted private international air law treaty and has played major role on the carrier's liability in international aviation transport industry. But the whole Warsaw System, though it was revised many times to meet the rapid developments of the aviation transport industry, is so complicated, tangled and outdated. This thesis, therefore, aim to introduce the Montreal Convention by interpreting it as a new legal instrument on the air carrier's liability, specially on the passenger's, and analyzing all the issues relating to it. The Montreal Convention markedly changed the rules governing international carriage by air. The Montreal Convention has modernized and consolidated the old Warsaw System of international instruments of private international air law into one legal instrument. One of the most significant features of the Montreal Convention is that it sifted its priority to the protection of the interest of the consumers from the protection of the carrier which originally the Warsaw Convention intended to protect the fledgling international air transport business. Two major features of the Montreal Convention adopts are the Two-tier Liability System and the Fifth Jurisdiction. In case of death or bodily injury to passengers, the Montreal Convention introduces a two-tier liability system. The first tier includes strict liability up to 100,000SDR, irrespective of carriers' fault. The second tier is based on presumption of fault of carrier and has no limit of liability. Regarding Jurisdiction, the Montreal Convention expands upon the four jurisdiction in which the carrier could be sued by adding a fifth jurisdiction, i.e., a passenger can bring suit in a country in which he or she has their permanent and principal residence and in which the carrier provides a services for the carriage of passengers by either its own aircraft or through a commercial agreement. Other features are introducing the advance payment, electronic ticketing, compulsory insurance and regulation on the contracting and actual carrier etc. As we see some major features of the Montreal Convention, the Convention heralds the single biggest change in the international aviation liability and there can be no doubt it will prevail the international aviation transport world in the future. Our government signed this Convention on 20th Sep. 2007 and it came into effect on 29th Dec. 2007 domestically. Thus, it was recognized that domestic carriers can adequately and independently manage the change of risks of liability. I, therefore, would like to suggest our country's aviation industry including newly-born low cost carrier prepare some countermeasures domestically that are necessary to the enforcement of the Convention.

Recently, the number of road construction is increasing by industrial development. According to this industrial tendency, the number of traffic accidents are consistently increasing due to increasing number of vehicle on the road. This is mainly because traffic accidents are occurred by various parameter such as negligence of driver, vehicle defects, state of unstable road, natural environment etc. Lane department of vehicles from guardrail is occurring frequently. This type of accident is caused by vehicle performance improvement and shape of vehicle, weak guardrail installation and maintenance. Guardrail has the purpose on prevention such as prevention of traffic accident and prevention of deviating out of road, minimizing damage of driver and vehicle by collision as well as entry into the road through guardrail. Stability evaluation test of guardrail verifies the behavior of guardrail through the crash of truck. At this time, the crash condition has 100 km/h of velocity and $15^{\circ}$ of impact angle. In the case of ground condition, filling slope condition has relatively high bearing capacity of infinite ground towards the test. Guardrail is generally installed on road of shoulder in fill slope in korea. It is possible for stability problem to deteriorate ground bearing capacity in Guardrail in fill slope. The existed study towards stability of guardrail has been carried out in the infinite ground. However, the study on the behavior of fill slope with guardrail is not performed by vehicle collision. Therefore, In this study, the numerical analysis using LS-DYNA was executed for verification on behavior of fill slope with guardrail through vehicle collision. This numerical analysis was carried out with change of embedded depth on installed guardrail post in shoulder of fill slope by vehicle collision and 8 tonf truck crash providing at NCAN (National Crash Analysis Center). As the result, displacement and stress on fill slope are decreased in accordance with the increase of embedded depth of guardrail post. Ground bearing capacity is deteriorated at depth of 450 mm form shoulder of road on fill slope.

Medium to large post structures installed along the roadside without proper protection can lead to serious vehicle damage and occupant injury at the impact. In North America and Europe, splitting systems such as slip base or breakaway device are used to reduce impacts. But the system has the risk of secondary accident when the splitted post falls down to the traffic or pedestrian. Sliding Post have been proposed as a way to solve this problem. By studying the crash test results of the 1.3ton and 0.9ton vehicle with 60 km/h and 80 km/h to a Rigidly Fixed Post (RFP) and Sliding Post (SP), danger of the conventional RFP and crashworthiness of the SP have been proven. While collision analysis only from the acceleration measured at the center of the vehicle assumes the motion of the post is the same as that of the vehicle, in this paper, by adding high speed film data to the analysis with vehicle acceleration could have separate the post motion from the vehicle motion. It gives better explanations on the movement of post and vehicle in each distinctive time step and provides basics to the crashworthy post design.

This paper evaluated the performance of passenger vehicles with an AEB(Autonomous Emergency Braking) for various pedestrian-vehicle collision situations. The experiment was conducted at a speed of 30-60km/h on a 2017 3,000cc vehicle using a range of collision scenarios. The results showed that the test vehicle stopped before crashing a pedestrian dummy under all scenarios at 30km/h. The test vehicle reduced the speed but crashed the pedestrian dummy in all scenarios at 40-60km/h. From the paired t-test, there was a speed difference from the AEB system at a significant level of 0.05. In addition, the percentage of speed reduction was quite different for each scenario tested. It was concluded that the current AEB system can prevent pedestrian collisions at speed of 30km/h, but cannot prevent collisions with pedestrians at speed of 40-60 km/h.

우리나라는 2004년 4월 경부고속철도개통을 앞두고 마지막 준비를 하고 있다. 1964년10월 고속철도를 가장 먼저 개통한 일본을 비롯한 프랑스, 독일 등은 이미 고속철도가 철도교통의 중심은 물론 각국의 교통수송에 높은 비중을 차지하고 있다. 2001년에 일본이 경우 1일 773,951명을 수송하고 있으며, 프랑스는 228,714명을 수송하고 있다. 세계적으로도 고속철도는 2000년 현재 유럽이 15,350km, 아시아는 2,152,9km를 운영 중에 있는데 이는 2010년에는 유럽은 41,350km, 아시아는 4,755.7km로 증가될 전망이다. 특히 아시아는 2005년 10월 개통예정인 대만의 타이페이와 카오슝의 345km를 비롯하여, 중국은 상해~북경의 1,330km를 2008년 ㅂ구경올림픽에 맞추어 개통을 준비하고 있다. 일본, 프랑스, 독일 등 고속철도의 운영국가들은 고속철도수송의 수송량이 급격하게 증가하고 있다. 프랑스는 인기준으로 1996년에 비해 2001년에 49.3%, 독인은 1996년에 비해 2001년에 70.1%의 증가치를 보이고 있다. 철도수송에서의 고속철도의 비중도 높아 인${\cdot}$km기준으로 일본은 29%, 프랑스는 48.3%, 독일은 15.9%를 차지하고 있다. 이러한 고속철도가 발전한 요인은 항공기와도 경쟁이 될 정도의 빠른 속도와 안전, 높은 사회경제적 효과에 기인하고 있다. 고속철도의 비중이 높은 일본의 경우는 개통 이래 현재까지 약 62억명을 수송하고 있는데 사망사고는 한건도 없었다. 또한 1개 열차의 정시도착 오차는 24초에 불과하고, 항공기와도 경쟁력이 될 정도의 속도와 수송능력을 보유하고 있다. 실제로 500~700km구간에서 항공기와 고속철도이 경쟁이 치열한데 고속철도의 분담율이 67%를 차지하고 있다. 이러한 고속철도 발전으로 철도수송의 증가율에도 큰 영향을 미치고 있다. 프랑스와 독일의 경우는 자동차수송보다 철도수송이 최근 4년간 약 10%이상 증가하고 있는 것도 고속철도의 영향에 기인하고 있다. 고속철도의 또 다른 특징으로는 높은 유발수요효과로 일본의 신간선개통전후를 비교해 보면 예상치보다 약 6%~23%의 높은 수요유발효과를 보이고 있다. 이 결과 각궁의 고속철도는 매우 높은 수익성을 기록하고 있는데 일본은 개통 후 3년째 흑자를 기록하였고, 중국도 개통 후 7년에 단년도 흑자를 예상하고 있다. 이러한 고속철도의 발전에 기초해 유럽을 비롯하여, 아시아 등에서 고속철도의 건설이 더욱 가속화 될 것으로 예상되는데, 이러한 새로운 변화의 고속철도시대에 대비하여 우리나라도 장차 건설계획수립, 해외수출, 고속철도의 상호운영 등을 지금부터 계획을 수립하여 집행해야 할 것이다.

Objectives To explore the traffic injury patients' experience on health care utilization of Korean Medicine (KM) practice and perception of health care system for developing a Korean medicine clinical practice guideline (CPG) of traffic injuries by survey method. Methods Two hundred ten patients in suffering from traffic injuries were surveyed from September 1st, 2019 to January 31th, 2020 at 2 University Hospitals (Pusan National Korean Medicine Hospital and Kyung Hee Korean Medicine Hospital at Gangdong) and 1 Spine Specialty Hospital (Jaseng Hospital of Korean Medicine). A structured questionnaire of experience on health care utilization of KM practice and perception of health care system of was distributed to responders by visits and all data were statistically analysed. Results Survey results showed high satisfaction of patients with the experience of KM treatments in order of daoyin exercise (7.8±2.3), chuna manual therapy (7.7±4.0), pharmacoacupuncture (7.4±3.0) etc. Safety concerns were reported in 9.1% subjects and 205 (97.6%) patients answered that collaboration with KM and western medicine is necessary for patients with traffic injuries. For the patients' requirement for extending insurance coverage, the most required therapy was chuna manual therapy (57.5%) and pharmacoacupuncture (42.0%). Conclusions This study presented the realistic patient-centered perception of KM practice and health care system in Korea. These results will provide basic data to be reflected in the process of adaptation for the revision of Korean Medicine CPG for traffic injuries.

Objectives This survey study is designed to check the awareness and satisfaction of Korean herbal medicine in patients suffering from acute traffic accidents. Methods From May 1 to 20, 2020, patients who visited the hospital within 7 days after the accident and received prescription of Korean herbal medicine for the first-time symptoms were selected. Survey was conducted 10 days after the first visit to confirm the perception of Korean herbal medicine and expected to be used as a prior study to improve the quality of Korean medicine led by Korean herbal medicine. Results Most patients answered that they were aware of the prescribed Korean herbal medicine's dosage and treatment effects. 65% of the patients said they would like to receive other forms of prescription if possible. Most patients answered that portability is convenient and tastes better than normal. 48% of the respondents said that it was the first to time to take Korean herbal medicine, and 68% said that they were willing to take the Korean herbal medicine later. At the time of the first visit, the health condition assessed using EuroQol visual analogue scale (EQ-VAS) was 46.84, but 10 days after the treatment began, it increased significantly to 61.93. Conclusions The improvement of symptoms and high satisfaction with Korean medicine medical services contributed to the patient's willingness to visit the Korean medicine hospital again and to respond that they were willing to take further medication. EQ-VAS elevation suggests that overall patients' subjective health conditions have improved since treatment.

Objectives This study was aimed to evaluate clinical practice guidelines (CPGs) of traffic injuries, which has already been developed at domestic or outside of country, and to explore the Korean medical treatments included in the CPGs. Methods Twelve electronic databases (PubMed, Cochrane library, China National Knowledge Infrastructure [CNKI {Chinese Academic Journals, CAJ}], Research Information Sharing Service [RISS], Oriental Medicine Advanced Searching Integrated System [OASIS], KoreaMed, Korean Medical Guideline Information [KoMGI), National Guideline Clearinghouse [AHRQ], Core Outcome Measures in Effectiveness Trials Initiative Website [COMET], Turning Research into Practice [TRIP], The National Institute for Health and Care Excellence [NICE], and Medical Research Information Center [MedRIC]) up to July 2021 were searched. Only systematically developed CPGs for traffic injuries were selected and appraised. The appraisal was conducted by using Appraisal of Guidelines for Research & Evaluation (AGREE) II tool. Results Six CPGs were included and evaluated. All CPGs were appraised as highly recommended because they exceeded 60% in more than 4 among 6 domains of AGREE II, including domain of 'rigor of development', and 30% in the rest. Recommendations related to Korean medicine treatments such as on manual therapy related to Chuna were given in 6 CPGs, 4 for acupuncture, 1 for Qigong and 1 for Taping. Conclusions The 6 CPGs were developed up to now through a systematic development methodology and there were many recommendations for Korean medical treatments related to manual (Chuna) treatment, acupuncture and Qigong. However, the evidence for the side effects and risk factors of Korean medical treatments was scantly reflected in CPGs. Therefore, it is considered that balanced CPG with benefits and risks should be developed, covering Korean medical diagnosis, treatment and prognosis.

Objectives: To investigate the prevalence of acute stress disorder (ASD) and post-traumatic stress disorder (PTSD) in patients with traffic injuries. In addition, PTSD patients was classified using 'pattern identification for jing ji and zheng chong'. Methods: Questionnaires such as the primary care PTSD screen for DSM-5(PC-PTSD-5), Korean version of PTSD checklist-5 (PCL-5-K), and the instrument of pattern identification for jing ji and zheng chong were conducted on 195 patients within 3 days to 1 year after traffic accidents. Patients were recruited from six medical institutions. Collected data were used to determine the prevalence of acute stress disorder and post-traumatic stress disorder. Results: On PC-PTSD-5, the prevalence was 39.1% for ASD and 50% for PTSD. On PCL-5-K, the prevalence was 20.4% for ASD and 29.3% for PTSD. Satisfying both PC-PTSD-5 and PCL-5-K, the prevalence was 18.2% for ASD and 25.8% for PTSD. As a result of pattern identification for jing ji and zheng chong, 'weakness of heart and gall bladder type' accounted for the highest proportions in both ASD and PTSD groups. Conclusions: In this study, the prevalence was 39.1% for ASD and 50% for PTSD by PC-PTSD-5. Satisfying both PC-PTSD-5 and PCL-5-K, the prevalence was 18.2% for ASD and 25.8% for PTSD. Further large-scale prospective studies are needed to analyze the prevalence of ASD and PTSD, the rate of progression from ASD to PTSD, and the type of pattern identification.
