지진해일은 대규모 인명피해는 물론 가공할만한 파괴력으로 해안시설물, 즉 원자력발전소, 항만시설물, 연안공항 등을 파괴시킬 수 있다. 따라서 해안에 국가기간시설물을 건설할 때는 반드시 급습 가능한 지진해일을 설정하여 예기치 못한 지진해일의 급습에 대하여 안전한가 여부를 검토해야 한다. 본 연구에서는 부산광역시에 건설 예정인 가덕도 신공항에 대하여 지진해일 급습 가능성을 예측한다. 기존의 수치모형을 이용하여 공항부지에 영향을 끼칠 가능성이 높은 지진해일을 설정하여 수치해석을 수행하고 안전 여부를 검토한다. 본 연구에서 고려된 지진해일은 기 발생한 역사 지진해일과 발생 가능한 지진해일, 즉 가상 지진해일 등이며, 수치모형은 우리나라에서 많이 사용되고 있는 전파모형과 범람모형인 HYCEL-NAMI와 HYCEL-RUNUP을 결합하여 사용한다.

The purpose of this study is to find out what factors influence lawmakers' voting decisions in the plenary session. In particular, the study examines causes and characteristics of waffling and strategic waffling, which express opposition or abstention in a discharge petition or a vote at the plenary session despite participating in a bill sponsorship. The study on waffling is meaningful because it has not been covered in previous literatures. To this end, the Gadeokdo New Airport Special Act, which the National Assembly passed in February 2021, was set as an analysis target. The study examined the factors that affected legislators' voting decisions and participation in bill sponsorship and who were related with waffling. Statistical results showed that the age variable influenced the motion of the bill while seniority and party affiliation had an effect on the participation of the bill. Likewise, the study found that party affiliation and district had an influence on the approval of the bill. In addition, the analysis of waffling showed that lawmakers with higher seniority tended not to participate in the vote. It could be interpreted that lawmakers with more legislative experience judged that they would benefit from strategic waffling. There is a limit to understanding lawmakers' decision-making and waffling through a limited analysis of the Gadeokdo New Airport bill. However, given that lawmakers tend to choose avoidance strategies in ambiguous situations, and given the high intelligence of lawmakers who know better than anyone about the future impact of a new bill, the decision-making shown by lawmakers in each stage of the situation is a prudent judgment gained from their experience. It indicates that it is necessary to research the legislative activities of lawmakers in various ways.

It is anticipated that Gadeok New Airport will be constructed, and the entity responsible for its operation will be a new airport authority, not the existing airport corporation, as the Ministry of Land, Infrastructure and Transport has announced its plan to establish the Gadeok New Airport Construction Authority. Based on the precedents of existing airport corporations, it is expected that the future authority will undergo organizational changes to become an airport corporation. This study seeks to establish criteria for selecting overseas airports for benchmarking when researching the entity that will operate the newly established Gadeok New Airport authority. To provide a specific basis for selecting overseas airports for the future operation of Gadeok Airport, the Delphi survey method will be used to derive criteria. Currently, when examining the participation of local governments in regional airports, Gimhae International Airport is operated solely by the Korea Airports Corporation, receiving criticism for the lack of participation by the local government, such as Busan City, in decision-making related to airport operation and local reinvestment. Therefore, it is deemed necessary to provide early direction for improvement in this regard.

Conflicts in the construction of large public facilities carried out as national projects are crucial issues we have to deal with. There are growing concerns for and oppositions to large construction projects in terms of environmental deterioration and the dissolution of local communities. In the case of projects that promise the creation of jobs and investment, the competition and disputes are increasing and being intensified. Therefore, there is a considerable amount of study on the competitions and conflicts between regions. Previous studies have focused on the procedures of public policy, governance structure, the role of local media. Contrary to the previous studies, this study investigates the spatial ways of constructing conflicts. Based on the analysis of the project of "Southeastern New International Airport", there is a mismatch between the spatial boundary of cost/benefit and agents (regions) of disputes. The agents of conflicts also show the politics of multiple scales by constructing alliances and breaking the network in the process of the airport project. The findings suggest that the conflicts on regional development should be understood as the construction of dynamic regional politics on regional development rather than as the by-product in the practice of policies.

The Nakdong Delta can be identified by two different geomorphic units. The first one is the upper delta. This is mostly composed of inter-distributary islands that are largely influenced by fluvial processes and attributed to the development of these islands along the river. The other one is the lower delta which is mostly composed of beach ridges. Barrier islands are largely effected by wave processes promoted by the development almost at a right angle to the river. Influenced by the longshore current which flows to the same direction, barrier islands located in the Nakdong river estuary are developing from east to west direction. As a result, the eastern end of the barrier islands are growing toward the north-west direction effected by tidal current which moves toward the same direction. Barrier islands include the Sinho Island, the Jinwoo Island, the Daema deung, the Janga Island, the Baghap deung, the Sae deung, and the Chulsae deung(Doyeo deung). They have orderly emerged from the sea since 1861. Since 2008, a new Deung, a sand dune growing under sea, has been developing rapidly from Chulsae deung to the Dadaepo beach. It made the sailing of small fisher boats impossible. Tidal currents transported a lot of sand and silt around the barrier islands. The landscape of Nakdong river estuary where many barrier islands are distributed will change rapidly affecting land environment.

The purpose of this study is to understand the effect of airport staff's attachment and participation to Incheon International Airport on satisfaction through mediating effects of development support and negative perception. This paper surveyed airline staff who worked at airport and conducted an empirical analysis based on survey results. This is because the effect of community members' attachment on satisfaction has been reviewed quite substantially. However, there has been insufficient research on the effect of attachment and participation on satisfaction through mediating effects of development support and emotional perception. According to empirical analysis, it was found that the participation of airport staff had a significant positive effect on satisfaction. In addition, support for development projects has also been proven to have a mediating effect. Following the empirical research results, this paper suggested implications for the 5^th development project at Incheon International Airport.
