Because passenger seat is one of the most important parts in the determination of passengers' satisfaction for train, it is absolutely important to design the passenger seat so that train passengers can satisfy. So, in the seat design it is necessary to consider passengers' characteristics, requirements, and dissatisfactions. However, passengers' dissatisfactions for the seat of Mugunghwa-ho train have been often raised through various routes. It is necessary to resolve their dissatisfactions to provide comfortable trip to passengers. So, we designed a new seat of Mugunghwa-ho train that resolved passengers' dissatisfactions. Our focusing design parts were the seat pan and the backrest of passenger seat. We investigated passengers' dissatisfactions for the seat of Mugunghwa-ho train through various methods and the human factors design guidelines through literature survey. We designed a new seat on the basis of investigated results. For newly designed seat, we evaluated comfort and sensible satisfaction in comparison with the existing seat. An experimental method and subjective methods were used in this evaluation. In all aspects, the new seat was superior to the existing.

본 연구는 실제 공항에서 수집되는 여객 데이터를 활용하여 공항 내 여객의 체류 시간을 분석한 연구이다. 여객의 체류 시간은 공항 터미널 설계, 공항의 수익성에 영향을 주어 중요한 여객 특성으로 간주되어 왔지만 실제 여객 데이터 수집의 어려움으로 그에 대한 분석이나 실시간 공항 운영에 활용하기가 어려웠다. 하지만 스마트 공항의 일환으로 세계 유수의 공항에서 방대한 양의 여객 데이터를 수집하고 있고, 축적된 데이터를 활용하여 공항 내 여객 체류 시간 분석이 가능해졌다. 본 연구에서는 인천 국제 공항에서 수집된 여객 데이터를 활용하여 여객 체류 시간 분석을 수행하였으며, 방대한 양의 자료를 효율적으로 처리하기 위해 데이터 마이닝 기법인 클러스터링을 활용하여 여객을 체류 시간에 따라 구분하였다. 분석 결과 인천 국제 공항 출발 여객은 체류 시간에 따라 1) 체류 시간이 짧고 대부분의 시간을 에어사이드에서 보내는 여객, 2) 평균 3 시간 정도의 체류 시간을 갖는 여객, 3) 총 체류 시간이 압도적으로 긴 여객 등 크게 3 개의 클러스터로 구분할 수 있는 것으로 나타났다.

An experimental method and a subjective method were used in this evaluation. In all aspects, new seat was superior to the existing.

In urban railways operated by 10 cars or 8 cars per trainset, passengers split up and board a train. On-board passengers for each car are not aware of congestion level of other cars of the train. Passengers waiting at stations can not predict congestion rate of the car which they get on. Therefore, the number of passengers is not equally distributed. The cars with a relatively low congestion level and the ones with a high level coexist in the train. The objective of this paper is to enhance passenger convenience and improve train operational efficiency through operational headway adjustments according to congestion level of each car. It also aims to spread passengers out evenly and assess the degree of congestion on each car by measuring the weight of each car including passengers during peak and off-peak hours.

The volume of transfer passengers now faces a crisis because the number of Chinese and Japanese passengers, the majority of transfer through Korea, is decreasing. This paper is analyzing the their air travel behaviors as well as characteristics of their transfer behaviors at airport. According to the research, it is suggested that transfer passengers perceive the importance of duty-free stores but their satisfaction of using duty-free stores during their transfer at Icheon airport was proven to be low. Considering the characteristics of transfer service quality at Incheon airport, waiting time of transfer is important but not satisfactory for them. Moreover, information of free transfer tour to city downtown and paid-in transfer tour for medical tourism is not known very well among North East Asian passengers. Thus, it is necessary to do detailed research of North East Asian transfer passengers, who have transferred through Incheon airport more than twice a year, to find out their exact needs of transfer tour in Korea.

본 연구는 환승승객을 대상으로 전체 서비스 수준을 평가 분석하는데 초점을 두고 수행되었다. 환승승객은 기존의 출발 도착승객들과는 다른 서비스 기대를 가지고 있으며, 공항에서의 환승객에 대한 중요성이 증가함에도 불구하고 아직까지 많은 연구가 이루어 지지 않고 있다. 이에 4년 연속 공항서비스 세계 1위인 인천국제공항의 환승승객의 서비스 수준을 평가하고자 가장 많은 환승 비율을 차지하는 일본과 중국 승객들을 중심으로 설문조사를 실시하여 환승승객들의 서비스평가에서 중요한 요인들을 고찰하고 각 서비스 요인들이 승객들의 만족도에 미치는 영향을 분석하고자 한다.

As the use of public transportation is increasing, a service considering the convenience of passengers is being launched utilizing the Internet (IoT) data collected through the bus information system. However, the bus information system only provides limited information such as the current location of the bus (GPS) and the expected arrival time at the stop. Additional IoT sensor information is needed to provide various services for the safety and convenience of passengers. In this paper, to improve the safety and convenience of passengers, we have added the boarding doors imaging sensor, temperature and humidity sensors, and sensor for measuring the number of passengers. The proposed IoT bus system can attach various sensors to buses to provide high-quality safety services to passengers.

As can be seen by the fact that 96% of foreign visitors to Korea travel by air, governments across Asia are aware of the importance civil aviation has in a country's economical developlment, and are fiercely investing in infrastructure and systems which could help set the ground for a hub strategy, catching the profits generated from air travel. In the case of Incheon Internation Airport (IIA), Chinese passengers have outnumbered Japanese passengers using IIA. Considering the potential growth of the Chinese air transport market, there is the growing need for thorough research regarding Chinese passengers. Surveys for the following study were distributed between September 2015 and October 2015, which includes Chinese holidays. Surveys were distributed to Chinese transfer passengers, with questions related to airport service and facility usage.

A self-administrated non-malignant respiratory symptoms questionnaire was sent to 1,099 citizens who take subway running in Seoul city. Symptom prevalence rate was high: 70.6% of subjects reported 'chest tightness', 43.4%, 'dysphnea'; 76.2%, 'dry cough'; 49.5%, 'runny nose'; 94.4%, 'drowsiness' when they take subway. The groups responding significant higher respiratory and drowsiness symptoms were 'young passengers' (vs elderly passengers), 'the female' (vs male), 'using subway everyday' (vs often), 'using subway for rush-hour time' (vs other than rush-hour), 'using transfer subway' (no transfer), 'using underground track' (vs ground track). Logistic. regression model was employed to find personal and subway characteristics affecting non-malignant respiratory symptoms. This study concluded that respiratory diseases history such as asthma, rhinitis, sinusitis, hypersensitivity pneumonitis significantly affect 'dry cough' and 'runny nose'. Thus, passengers with respiratory diseases history shows 2.8 times greater 'dry cough' than and 3.4 times greater 'runny nose' than those passengers without respiratory diseases history felt. This results indicated that several measures have to take to protect sensitive groups such as passengers with respiratory diseases, children and elderly people. Also passenger who use to transfer shows 1.7 times higher runny nose symptoms than that passenger who do not transfer felt.

This paper tried to find out what the main factors are to impact on satisfaction level of transit passengers at Incheon airport. Incheon airport has made lots of transit facilities and services to attract transit passengers from neighboring airports to increase transit rate as high as advanced foreign airports such as Heathrow, Schiphol and Hong Kong. A survey was performed on 450 transit passengers resting at airport transit lounge in airside area. According to the result, it was found out to be significant factors affecting satisfaction of transit that convenience of security screening, price of duty-free product, a direction board & signage and terminal orientation among Chinese transit passengers. On the other hands, it seemed that Japanese transit passengers thought diversity of airline routes, convenient transfer flight schedule, total transit time and terminal orientation are major variables affecting their satisfaction. Considering the effect of demographic factors, Chinese passenger's satisfaction was more affected by age, travel purpose, the number of travel per year and flight destinations. However, Japanese transit passenger's satisfaction was only affected by the flight destinations, especially willing to travel to North America and Europe.
