본 연구는 인천국제공항에서 근무하는 항공사 종사자 대상으로 그들이 승객에게 서비스를 제공하는 동안 종사자 사이에 안전문화가 제대로 정착되어 승객들에게 안전에 대한 기본사항이 제대로 전달되고 있는 지 실증 분석하고자 하였다. 항공사 종사자들이 인식하는 안전문화가 그들이 공항이용객에게 제공하는 서비스품질 인식에 어떠한 영향을 미치고 이러한 서비스품질이 궁극적으로 직원의 서비스 제공 행동(서비스 효능감)에 어떠한 영향을 미치는 지 검증하는 연구를 수행하고자 하였다. 연구자는 이상의 연구 목적을 바탕으로 항공사 직원들의 안전업무역량을 통해 궁극적으로 항공서비스의 품질도 향상시키고 항공사의 접점 서비스 직원들을 관리할 수 있는 관리자적 시사점을 제공하고자 하였다. 항공사 종사자들을 대상으로 한 실증분석 결과 안전문화 구성요인들인 보고/학습 문화와 공정문화 중 공정문화는 항공사의 서비스 품질 향상과 항공사 종사자들의 서비스 효용성 증대에 매우 긍정적인 기여를 하는 것으로 나타났다. 반면에 보고/학습 문화는 오히려 공항에서 서비스 품질 향상을 저해하고 종사자의 서비스 효용성 의지를 약화시키는 요인으로 작용할 수 있음이 파악되었다. 비록 현장에서 직원의 서비스 실수가 있더라도 필수적인 안전정보를 제공하는 행위였다면 이를 배려하고 심지어 보상까지 해주는 문화가 정착될 때 서비스 품질향상에 대한 동기부여가 될 수 있을 것이다.

국제민간항공기구, ICAO(International Civil Aviation Organization)에서는 CNS/ATM(Communication Navigation Surveillance/Air Traffic Management)을 21세기 표준항행시스템으로 채택하기로 결의하였다. 이에 따라 ICAO 회원국은 관련 기술개발 및 인프라 구축에 박차를 가하고 있다. CNS/ATM의 항공 감시분야에서는 ADS-B(Automatic Dependent Surveillance-Broadcast) 시스템과 더불어 Multilateration이 구축되고 있다. Multilateration은 레이더 설치 및 운용이 곤란하거나 항공기 감시 사각지대를 보완하기 위해 설치하는 시스템으로 TDOA(Time Difference Of Arrival)를 이용하여 레이더에 비해 매우 정확하다. 본 논문에서는 레이더 시스템에 널리 사용되는 IMM(Interacting Multiple Model) 필터를 Multilateration에 적용하여 보다 정확한 항공기 위치 획득을 가능하게 하였다. 성능분석 결과, IMM 필터를 적용한 Multilateration이 기존의 Multilateration에 비해 공항 인근에서는 38.37%, 공항 10마일 부근에서는 20.86% 정확한 것으로 분석되었다.

Simultaneous parallel approaches in all weather conditions should be applied to manage efficiently increasing volume of air traffic flow and solve the problem of delayed arrivals. But All of the airports which have closely-spaced parallel-runways in Korea don't meet the interval-standards for IFR parallel approaches. In that regard, more accurate and safer System should be applied for the Korean airports. GNSS was adopted as an international standard of the next-generation navigation system and many studies and master plans have been activated by stages in Korea. In this paper, the current state of the domestic airports will be analyzed focusing on the interval of parallel runways and future specification of both flight operation system and air-side management will be recommended.

This paper proposes arrival scheduling and advisory generation algorithms which can be used in the terminal airspace with Point-Merge procedures. The proposed scheduling algorithm consists of two steps. In the first step, the algorithm computes aircraft schedules at the entrance of the Point-Merge sequencing legs based on First-Come First-Served(FCFS) strategy. Then, in the second step, optimal sequence and schedules of all aircraft at the runway are computed using Multi-Objective Dynamic Programming(MODP) method. Finally, the advisories that have to be provided to the air traffic controllers are generated. To demonstrate the proposed algorithms, the simulation was conducted based on Jeju International Airport environments.

The purpose of this study is to compare the characteristics of hospital websites across four nations(e.g., South Korea, Singapore, Thailand and India). We selected English websites of 58 hospitals with JCI accreditation. For the analysis of websites, we developed assessment tool with four domains(e.g., contents, convenience, design, interactivity). The results showed that Korean hospitals provided more channels for appointment on the website compared to other countries. In contrast, foreign hospitals used actively SNS(e.g., Facebook, Twitter or Youtube) on the websites. They also provided more information on diverse services(e.g., airport pickup services, treatment costs, consultation services).

Situation to develop Kyonggi Province area to universal tourist attraction area keeping in step with national large size event holding such as sun of Korean visit with opening a port of the In-chon International airport, the world ceramics Expo, World Cup was made up. Growth possibility is big to culture tourism resources and representative tourist resort of the Korea that use view of nature photon circle properly such as ceramics that target area possesses. Area development plan through growth possibility should be arranged to international ceramics production complex and distribution complex. Therefore, plan analyzing future district theme establishment and strength in priority via past and present of target area.

This provided a basic frame to analyze the investment effect on the road, railroad, airport and port as a national dimension but it still has a limitation to analyze the specific economic and financial validities to consider the characteristics of the traffic facilities within the area. Conclusively, the aims of this study provide the reasonable evaluation guidelines effectively to the local automatic groups, especially Chungju in the frame of the present evaluation guidelines. We provide the adaptive alternatives on the present systems which are difficult to adapt to the present investment evaluation guidelines; the estimation method of the social economic index and the estimation method of the traffic demand. Additionally, we discuss the research method of the passage actual state for a reasonable estimation of the traffic demand. The result of this study will be activated for the validity check and construction plan of the reasonable traffic investment plan of Chungju city.

Project Financing(PF) was introduced from the way of banks' conditional financing that take buried oil as security and offer required money to oil explores which have weak loaning ability in the U.S. 1930s. After that PF has developed with financial market and it has been activated in the market of Korea since 'An Institution about Private Financing Invitation Promotion' was established. Started with I-Hwa Ryoung tunnel project, PF has been used in the Metropolitan Area Airport Highway and etc. But because of the risk that occurred by PF's complexity and uncertainty, PF has not been used fully and there are only few practical examples. The purpose of the present study is to investigate how to decrease, identify and extract the risky factors of project that being planned by PF.

This research is a literature survey on the Supply chain security. International organization and governments have build security regulations to improve the security in the shipment through supply chain. The researches on supply chain security were increasing during last 10 years. We were surveyed 53 research including Korean and international papers. ills study was classified by research subjects, security regulation, and research methods. Korean researches were focused to introducing and reviewing on the security regulation, but the researches on specific security reinforcement were very rare. International researches were concerned with the subject of the airport security scanning problem, transportation security problem, port selection problem.
