The administrative ship, Chuja-ho, is the only mode of transportation between manned islands in the Chuja-do, Jeju. Chuja-ho is a 25-year-old age, which is identified to pass the persisting period (25 years) for public ships, and there is an urgent need for a replacement. The residents of the island are also requesting that the new administrative ship be outfitted with medical functions because there is no sea transportation system for medical emergencies in Chuja-do. The purpose of this study is to examine the required functions of a new administrative ship outfitted with medical functions and to suggest a conceptual design. In order to review the necessity of an emergency patient transport system, user requirements were surveyed and analyzed, and the ship's condition assessed by ship experts who carried out an on-site survey and analysis of ship survey data. Thereafter, a conceptual design for a new administrative ship with medical functions was presented. The results of this study can be used during a review of a new budget plan and for basic ship designs during the replacement project by the local government. It is also expected to improve the safety and medical environment of Chuja-do residents.

Currently, the global climate change response paradigm has been changed to a universal response system in which all nations, not the developed countries, participate. Korea has also set a target of 25.9 million tons of transportation greenhouse gas reduction targets by 2030. Korean society is expected to enter the super aging society in 2026. In this study, to reduce the greenhouse gas emissions in public transport and to improve the convenience of transportation vulnerable, we estimate the willingness to pay(WTP) and social benefits assuming that the existing feeder buses are replaced with medium-sized low floor electric buses. To this end, survey was conducted on bus users in the metropolitan area and WTP was estimated by using contingent valuation method(CVM), which is one of the non-market value evaluation methods. As a result of estimation of WTP, the average WTP is 51.4 (won / time person), estimated the economic benefits were 50 million won on weekdays and 40 million won on weekends in Gyeonggi Province in 2014.

영국에서는 농촌문제의 심각성과 범정부적 대책 마련에 대한 부처간 인식 공유가 증가함에 따라 2000년 "농촌백서"에 '농촌서비스 표준화(Rural Services Standard, RSS)'를 제정하였다. RSS는 농촌 주민의 삶의 질 제고와 복지 서비스 향상을 위해 달성할 주요 서비스의 National Minimum을 의미한다. 매년 RSS 운용에 대한 지속적인 모니터링을 통하여 내용을 매년 업데이트 하고 있다. 교육 및 아동서비스, 광대역 통신, 사회적 돌봄, 우체국 서비스, 보건, 인터넷 접속, 긴급 서비스, 교통의 8개분야 13개 서비스 기준을 설정 제시하고 있다. 우리의 경우도 농촌 주민의 삶의 질 향상을 위한 범정부적 투자가 이루어져 왔지만 농촌지역의 사회서비스 기준을 도시와 비교해 보면 아직도 부족한 부분이 많이 있다. 농촌 인구가 감소되고 있는 상황에서 지속적인 하드웨어 중심적 투자에 대한 의문제기와 함께 농촌 주민들이 최소한의 공적 서비스를 활용할 수 있는 기반이 되어야한다는 의견이 대립되고 있는 가운데 그 해결책을 찾기 위하여 '농촌 서비스 기준'을 설정하자는 논의가 추진되고 있다. 이에 본 연구에서는 인구 5만 이상 군지역에 속하는 경상북도 울진군 기성면 척산리를 중심으로 농촌 정주지원 서비스 요구사항을 분석하였다. 척산리에는 총가구 187호 363명이 거주하고 있으며 지난 3년간 인구 이동이 전혀 없었다. 주민들의 연령대는 50~60대가 가장 많으며 척산 3리가 가장 고령화 되어 있는 것으로 나타났다. 교통 환경은 좋은 편이었는데 기성공용버스 정류장에 10곳 이상의 차편이 있고 7번 국도가 있어 타 지역으로 이동도 용이하였다. 마을에 보건/의료를 담당하는 곳은 보건진료소뿐이었으며 잦은 외근과 구급약 부족 등으로 불편을 호소하고 있었다. 응급상황 발생시 수송 가능한 응급체계는 갖춰져 있지 않았고 노인들이 가장 많이 이용하는 물리 치료실은 일주일에 3번 개방하기에 불편하다고 하였다. 3층 건물의 복지회관이 있으나 장날(5일장; 1일, 5일)만 개방되어 이용에 한계가 있었고 마을주민을 위해 운영되는 프로그램은 없었다. 논농사 중심의 경제생활이었고, 부녀회와 청년회 등은 면단위 또는 행정리로 묶어서 운영하고 있었다. 주민들은 울진군 면소재지 중 척산리에만 약국이 없어 불편한 사항이 많기에 약국, 물리치료실의 상시 개방을 필요로 하였으며 장날을 이용한 노인대상 영화상영, 강연회 등 다양한 문화프로그램 운영을 희망하였다.

This paper presents numerical results of static structural stability analysis in development of a vertical transfer device of a PRT(Personal Rapid Transit) vehicle. The vertical transfer of a fully occupied vehicle operating on a road network is the first attempt, which is expected to contribute to overcome the limitations of conventional 2-dimensional operation mode. In particular, the vertical transfer apparatus designed based on vertical circulating conveyors is capable of continuous transfer without time delay so that it enables to accommodate a high traffic density. This system has been frequently used in a logistics field; however, it is essential to assess a structural integrity because an external force by a vehicle weight is exerted on the conveyors in the form of a concentrated load unlike a conventional logistic transport. In this study, prior to the production process, the structural performance of the pilot design in an early stage is numerically evaluated using the commercial finite element method (FEM) solver (i.e., $Ansys^{(R)}$).

The first successful sustained powered flight by Wright Brothers was further extended to the rapid development of aviation technology, that led to transpacific flights, the invention of supersonic planes, and enabled hundreds of people to travel in the space, in addition to the fact that around 10 people had stepped on the moon, all of which were made possible within the very same century. However, on the back side of this most wondrous human technology, the vulnerableness to the aviation accident has been constantly accompanied with, right from the very beginning stage of the aircraft development. Moreover, the development of future aircraft is being focused on the aircraft performance, the increment of the number of passengers aboard and also its speed. In proportion to these phenomena of mega sizing the aircraft, the development of new technology and the increment of air traffic volume, the number of aviation accident is expected to augment, resulting in the enormous loss of human lives and properties. In order to prevent the disastrous aviation accident as such, it is essential to conduct the accident investigation in a specialized, systematic and scientific manner. In search for the method to attain the effective function of the aviation accident investigation organization, in this study, issues were examined as follows: The full-time Board Members and the establishment of an integrated investigation agency, The systematized security of status as an accident investigator, Inclusion of a human factors specialist in the investigator group organization, liability limit of an accident investigator Stipulation of the definition and the investigation scope of an accident and serious incident, along with the main body of conducting the investigation into the accident involving both civil and public aircraft, in the regulations related to the accident investigation.

In recent years, unexpected bridge fire accidents have increased because of augmenting the number of traffic volumes and hazardous materials by the increment in traffics and distribution business. Furthermore, in accordance with the effort of using the under space of bridges, the ratio of occupied by combustible materials like oil tanker or lorry has been increased. As a result, the occurrence of bridge fire has been growing drastically. In order to mitigate the accident of bridge fire, risk assessment of bridge fire has been studied, however, practical risk models considering safety from users' viewpoints were scarce. This study represented quantitative risk assessment model applicable to national road bridges in Korea. The primary factors with significant impacts on bridge fire accidents was chosen such as clearance height, materials of bridges, arrival time of fire truck and fire intensity. The selected factors were used for Fire Dynamics Simulation (FDS) and the peak temperature calculated by FDS in accordance with the fire duration and fire intensity. The risk assessment model in bridge fire reflected the FDS analysis results, the fire damage criteria, and the grade of fire truck arrival time was established. Response plans for bridge fire accidents according to the risk assessment output has been discussed. Lastly, distances between bridges and fire stations were calculated by GIS network analysis. Based on the suggested assessment model and methodology, sample bridges were selected and graded for the risk assessment.

This study investigates the initiatives of Gangwon sea routes based on precedent studies on the North Pole route to suggest a multi-modal buildup of transport logistics network of Gangwon harbors for the strengthening of logistics efficiency in the Korean Peninsula. The findings were: First, the government should expand railway infrastructure in Gangwon. Second, harbors in Gangwon should each have one speciality to strengthen connection with other harbors by using railway oriented background transportation network. Third, the government should develop industries of EFEZ(East coast Free Economic Zone) in the East Sea Coast in Gangwon to connect resources from the North Pole Sea. Fourth, the government should invite the base of Araon Ho's polar research vessel to play the role of the North Pole Sea route in the near future. Fifth, the government should strengthen the role of the Samcheock LNG base under construction. SIxth, environment-friendly transportation technology should be introduced to reduce carbon emission as much as possible. Lastly, an optimum North Pole logistics route should be developed to connect the Metropolitan area(Metropolitan Economic Zone), Gangwon roads and railway, Gangwon habor, Trans-Siberian Railway and thw North Pole route, and Europe, to strengthen national foreign trade power in the near future.

The aim of this study is to determine factors that affect the competitiveness and the move-in environment of migration companies according to the recent change of location conditions of industrial complexes. The results of analysis show that productive factor and economic factor are related to the main factors that determine the location environment. The resident companies have a strong link to the economic characteristics factors, which seems to be related to the expectation and satisfaction for public support facilities, hospitals, educational institutions, and administrative agencies to be placed in the complex, encouraging companies to be located in the complex. In other words, if the existing economic factors and public support facilities were complemented, it can be inferred that the industrial complex promotion policies will be more effectively planned. Also, transportation and infrastructure facilities are analyzed as successful factors for resident companies. In addition, the economic and productive environments turn out to affect public support facilities and environmental factors of infrastructure as major factors. The results of this study are expected to be a useful guideline in determining the resident policy or external factors for the future industrial complex.

To cope with the increased demand on the intra-city transportation by urban rails, the introduction of the light rail transit (LRT) systems has been expedited in Korea due to the possible reduction of both the development and operation costs from adopting LRT systems. The LRT systems have so far been designed, constructed and operated based on the corresponding law and regulations. It has been conceived that fully complying with the existing guidelines may incur some extra costs on LRT. In addition, the present design of LRT stations seems to require unnecessarily long flow of passengers traffic, particularly for disabled people. In this paper, as an approach to solving the aforementioned issues, an introduction of 'LRT stops' has been studied where the stops are similar in concept to bus stops and are intended to replace the stations of a bigger scale in general. Specifically, necessary guidelines for design have been developed by modifying the existing ones to be fit with LRT stops. A design case was also presented to evaluate them. The effective use of the results reported here will provide an opportunity of cost reduction in connection with the construction and operation, and also let people benefit from convenient use of rails, thereby resulting in enhanced transportation welfare.

Recently, interest in supply chain management is rising along with the increasing oil prices and traffic congestion. In particular, people started studying the issue, but realized that advantageous strategies for suppliers and retailers are not always advantageous to a carrier. Therefore, in this study the atuhors set up a simulation scenario to understand delivery vehicle routing problems under various inventory policies, namely Economic Order Quantity (EOQ) and Periodic Order Quantity (POQ) and network configurations. First, the authors made a virtual supply chain. Then they analyzed characteristics of delivery vehicle routing under various inventory policies (EOQ and POQ) and network configurations. As a result, the POQ inventory policy decreases the number of vehicles, the number of drivers, and the service time of vehicles. Also, the centralized network increases the load factor of vehicles and decreases the service time of vehicles. In other words, the centralized network and the POQ inventory policy are better for the carrier. These results show a savings of 15,556,806 won ($13,389.10) in a month: a reduction of 17%.
