  • 지속적인 고속도로망 확충과 고속철도 개통 등에 따라fr개선 항공수요가 계속 감소하고 있다. 이러한 상황에서 각 공항과 지방자치단체에서는 지방공항을 살리기 위한 대책 마련에 심혈을 기울이고 있다. 이런 측면에서 본 연구는 고속철도의 등장으로 인한 대구국제공항의 현황을 분석하구 공항의 활성화를 위한 방안을 도출하고 대구공항개발에 대한 장 중단기간의 역할에 대한 로드맵을 제시하여 대구국제공항의 활성화를 통한 경쟁력을 확보할 수 있는 실질적인 이행방안을 제시하였다. 이런 관점에서, 대구시에 대구국제공항의 활성화를 위한 전담기구를 조직하여 일관적인 수요진작을 위한 지역 여행사지원, 대구국제공항을 주요항공 기지로 사용할 항공사의 지원, 일본의 지방도시에서 새롭게 개장하고 있는 공항에 대한 우선적 노선 개설, 중화권으로의 노선개설 및 확대 등을 적극적으로 추진할 것을 제안하였다. 건설교통부 차원에서는 인천국제공항의 허브화 지원만을 주요공항정책의 수단으로 삼고 있으나, 인천국제공항은 국가를 대표하는 공항으로 하되 수요의 흡수는 광역 수도권으로 하고, 향후 서해안권과 영남권의 거점 공항을 육성 할 필요가 있다. 국내 지방공항의 항공수요는지역인근의 자체 기종점 수요를 기반으로 하고 있어서 다거점 (1강 2중과 제주)으로 육성 할 필요가 있다는 견해를 제시하였다.

  • Recently, Intense competition is expected to bring about continuous change with the rapid global aviation industry. In particular, domestic passenger demand has been steadily increasing over the past five years, with domestic and international shipments growing at a CAGR of 8.4% and 10.0%, respectively. In addition to the economic value of the airport, social interest due to greenhouse gas emissions is also rising. In this study, we analyzed the efficiency of airport operation by using DEA model(Directional Technology Distance Function) considering undesirable output for 14 airports in Korea. As a result of analysis, all airports except Gimhae, Yangyang, Cheongju and Yeosu were analyzed as efficient airports. However, only Gimpo, Gimhae, Jeju, Muan, Daegu and Gwangju were analyzed as efficient airports considering the undesirable output.

  • 인천국제공항 버스 노선망의 형성과 그 요인을 밝히기 위하여 사회 경제적 관점에서 분석한 결과는 다음과 같다. 수도권과 충청도, 전주 익산을 배후지로 한 김포국제공항의 노선버스는 인천국제공항이 개항되면서 강원도와 광주, 나아가 영남지방의 주요 도시와도 노선이 개설되고 수도권도 노선망이 더욱 확충되었다. 인천국제공항 버스운행은 단독 또는 복수의 사업체가 노선을 개설했는데, 공동운행을 하는 경우는 수익성이 불확실하거나 지역연고의 노선을 확보하기 위함이다. 항공기여객밀도와 버스 편도 운행회수와의 분석에서 강서구를 제외한 서울시와 서울시의 위성도시인 수원 성남 안양 군포 구리 오산시는 운행회수를 감소시키고, 나머지 시 군 구는 운행회수를 증가시켜야 할 것이다. 수도권의 경우 노선버스와 지하철(전철)과의 운임과 최단소요시간을 비교해 보면 노선버스의 운임은 비싸지만 소요시간이 짧고, 또 환승의 불편이 없기 때문에 이용객이 지하철(전철)보다 많이 이용한다고 할 수 있다. 한편 비수도권에서는 남동부 주변지역에 공항이 분포한 지역은 국내항공기가 노선버스보다 우위에 있으나 대구와 공항이 입지하지 않는 지역은 노선버스가 우위를 나타내고 있다는 점이 밝혀졌다.

  • Characteristics of urban wanning phenomenon were studied using degree days for three big cities(Seoul, Busan, Daegu) adjacent to airport. Time variation of the cooling and heating degree days was analyzed using the daily mean air temperature data measured at the six meteorological observatory for long-term periods(25~43years). The results for the big cities are as followings: 1) It was found that the heating degree days trended to decrease from year to year. 2) The cooling degree days were nearly unchanged during the same analysis periods. 3) The number of days calling for air-heating also tended to decrease as time passes. 4) Those of air-cooling were nearly unchanged during the same time. It suggests that the change of air-heating condition owing to urbanization came in evidence in the winter season, but that of air-cooling condition was slight in the summer season. On the other hand, the long-term trends of degree days were very small in airport areas except for Kimhae airport. Hence, the gaps of degree days between big cities and rural airport areas are increasing.

  • In recent years, video detection systems have been implemented in various infrastructures such as airport, public transportation, power generation system, water dam and so on. Recognizing moving objects in video sequence is an important problem in computer vision, with applications in several fields, such as video surveillance and target tracking. Segmentation and tracking of multiple vehicles in crowded situations is made difficult by inter-object occlusion. In the system described in this paper, the mean shift algorithm is firstly used to filter and segment a color vehicle image in order to get candidate regions. These candidate regions are then analyzed and classified in order to decide whether a candidate region contains a license plate or not. And then some characters in the license plate is recognized by using the fuzzy ARTMAP neural network, which is a relatively new architecture of the neural network family and has the capability to learn incrementally unlike the conventional BP network. We finally design a license plate recognition system using the mean shift algorithm and fuzzy ARTMAP neural network and show its performance via some computer simulations.

  • There have been recently introduced new types of urban metro vehicles called LRT (Light Rail Transit) running on elevated guideway such as Uijeongbu VAL(which stands for V$\acute{e}$hicule Automatique L$\acute{e}$ger: Automatic Light Rail Vehicle) system, Yong-In LIM(Linear Induction Motor) system, Incheon international airport MAGLEV(Magnetic Levitated Vehicle) system and Daegu monorail system. Most of accidents by the vehicles are bound to happen on elevated guideway. Therefore, it is of vital importance to analyze hazards related to vehicles running on elevated guideway and study emergency evacuation scenarios applicable in case of accidents on elevated guideway so as to secure the safety of the new types of urban metro vehicles. In this study, FTA(Fault Tree Analysis) model was developed to identify all possible hazards, and all possible evacuation scenarios were studied. It was also confirmed that each hazard can be corresponded to one or more evacuation scenarios. This result shows that passengers can be evacuated according to one of the scenarios identified in this study in case of an accident of "Train Stranded on Elevated Guideway".

  • 2010년 아이슬란드 화산재로 인해 유럽 전역에 항공대란과 많은 경제적 피해가 발생한 일이 있다. 최근 학계에서는 백두산의 화산폭발 가능성이 높다고 경고하고 있는데, 만약 백두산 화산이 폭발한다면, 특히 운항중단으로 인한 항공산업의 경제적 피해가 우려되고 있다. 본 연구에서는 백두산 화산재 확산 시나리오를 기반으로 시간과 위치에 따른 화산재 PM10 농도를 분석하고, 항공운항 기준에 따른 공항의 피해범위를 예상하였다. 항공산업의 경제적 피해액을 예측하기 위해 국내 항공사 및 공항공사의 매출규모를 항공사·공항·월 단위로 분류하고, 항공기 운항이 중단될 경우 항공사 및 공항공사의 직접피해액을 계산하였다. 그리고 산업연관분석을 통해 항공산업의 피해로 인해 발생되는 연관 산업의 생산·수입·부가가치에 미치는 파급효과로 인한 간접피해액을 계산하였다. 연구결과, 화산폭발지수가 VEI 1에서 VEI 5일 경우 공항의 직접피해는 나타나지 않았다. 그러나 VEI 6일 경우 강원도의 양양공항은 화산재 PM10 농도가 비행금지구역(NFZ)에 해당하여 항공기 운항이 전면 금지되며, 경상도의 김해공항, 울산공항, 포항공항은 시간제한구역(TLZ)에 해당되어 항공기 운항이 부분적으로 중단될 것이다. 만약 VEI 7일 경우에는 화산재가 강원도, 경기도, 충청도, 경상도 지역으로 확산되어 양양 공항, 김해공항, 대구공항, 울산공항, 포항공항은 항공운항이 전면 금지되며, 이때 항공사 및 공항의 총 경제적 피해액은 81억 원(직접피해액 35.5억 원, 간접피해액 45.7억 원)이 발생하는 것으로 예측되었다. 특히, 김해공항의 피해액이 92%를 차지하고 있어 화산재로 인한 피해가 가장 높은 공항으로 나타났다.

  • This study was concentrated on the development of the effective noise environmental education program(NEEP) for elementary student. And through this program, the student who is remaining as a spector or has not active attitude for noise problems will be encouraged to solve the troubles spontaneously. The object of this study was the two classes in H elementary school where is near to the Daegu international airport. One class that is a group for experiment has five NEEP lessons during five weeks in the time for the creative discretional activities. The other class, which was compared with the experimental group was given no lessons. NEEP was made on the bases that are the contents related with noise in 7th elementary education policy and the data developed by previous researchers. This program is containing basic concepts for noise and the effects of noise problems on human body or studying in class. And after using NEEP, students became more sensitive for noise environments than previous. And also students showed the positive attitude for solving noise troubles. It was meaningful in the level of p<.001 that the result of noise knowledge and awareness in the pre-post test within experiment group. However, all of the results in comparison group didn't represent statistically meaningful difference. And there were meaningful differences between experiment and comparison group after carrying out NEEP. In the area of noise knowledge and awareness, there were clearly meaningful results in the level of p<.001. Although the difference in noise attitude was a little, it was analyzed to have not a meaningful result. What suggested for researches in future are as follows. First, because until now the concrete research for the elementary student who exposed to noise and experienced a difficulty in hearing is deficient, many studies are needed. Second, NEEP with more lessons is required because the change of effective attitude needs long term. Third, due to the student who exposed to noise generally has low ability for concentration, NEEP compensated with activities is needed.
