Asia's cruise industry is growing rapidly with the number of tourists increasing every year. This growth has encouraged intense competition among leading port cities in Asia to retain cruise tourists and cruise lines. The purpose of this study is to analyze the development of the cruise industry around Busan as a hybrid port city and propose new strategies for improving Busan's competitiveness. To achieve these goals, factor analysis and Importance-performance analysis (IPA) are used. The analyses results suggest that the development possibility of Busan as a cruise center is dependent on the improvement of certain factors, including the variety of inland tour options, unique experience, direct service infrastructure, tourist attractions, wide accessibility to other modes, and strong connection to attraction. In addition, the city needs to meet other requirements, including developing various tours, tourist products, and fly & cruise packages and hosting international festivals that can represent Busan and cater to potential cruise customers. Moreover, the city desperately needs to expand its commercial and cultural space by redeveloping its cruise terminals.

The purpose of this paper is to measure the clustering change and analyze empirical results. Additionally, by using k-means, hierarchical, and mixed models on Asian container ports over the period 2006-2015, the study aims to form a cluster comprising Busan, Incheon, and Gwangyang ports. The models consider the number of cranes, depth, birth length, and total area as inputs and container twenty-foot equivalent units(TEU) as output. Following are the main empirical results. First, ranking order according to the increasing ratio during the 10 years analysis shows that the value for average linkage(AL), mixed ward, rule of thumb(RT)& elbow, ward, and mixed AL are 42.04% up, 35.01% up, 30.47%up, and 23.65% up, respectively. Second, according to the RT and elbow models, the three Korean ports can be clustered with Asian ports in the following manner: Busan Port(Hong Kong, Guangzhou, Qingdao, and Singapore), Incheon Port(Tokyo, Nagoya, Osaka, Manila, and Bangkok), and Gwangyang Port(Gungzhou, Ningbo, Qingdao, and Kasiung). Third, optimal clustering numbers are as follows: AL(6), Mixed Ward(5), RT&elbow(4), Ward(5), and Mixed AL(6). Fourth, empirical clustering results match with those of questionnaire-Busan Port(80%), Incheon Port(17%), and Gwangyang Port(50%). The policy implication is that related parties of Korean seaports should introduce port improvement plans like the benchmarking of clustered seaports.

Recently, It became possible to transport freights and energy resources via Northern Sea Route(NSR) as global warming has been accelerated. As a result, all countries of the world and Korean local governments have had a struggle to take the advantageous position first in NSR development. However, this extreme competitions might have a negative effect on the national port industry and cause unnecessary social costs and economic losses. Therefore, the main target of this study is to find the most suitable port for NSR using AHP analysis. Most of the data was gained from previous literatures and public statistics and the weight of each factor was calculated by the result of expert survey. As a result, Busan port has the biggest competitiveness, followed by Yeosu Gwangyang, Ulsan and Incheon. From the result, this study suggested 3 possible scenarios. The first scenario specializing Busan port in NSR focuses more on developing the related businesses such as repair of ships, refueling, ship stores trade than attracting the more cargoes. the second is a strategy to make Ulsan port as a hub for energy resources, especially liquid cargo on NSR. the last is a mixed one to assign suitable roles to the ports according to their competitive capabilities.

The purpose of this paper is to analyze the efficiency of integrated management strategy between Busan and Gwangyang ports through considering the integrated management strategy of ports in China and Japan. The reason we selected Busan and Gwangyang ports is that these two ports are a major port which is possible to be an Asia hub port by the policy of Korean government, but these two ports are concerned that they are able to lose their competitiveness by excessive competition. Therefore, we attempted to analyze the integrated management strategy of China and Japan and then we examined the effectiveness of integrated management between Busan and Gwangyang ports. For empirical study, we assumed that the co-management of these two ports will enhance the port performances. And a comparative study has been conducted with 25 Asian ports by using Data Envelopment Analysis (DEA) method. We also tried to compare the efficiency between before integrated management and after integrated management of these two ports. The result of analysis indicates that the port performance of these two ports has been increased slightly in integrated management system, but the efficiency of these two ports is still lower than other competitors such as Chinese and Japanese ports. It means that there exists inefficiency in management of these two Korean ports because Korean ports are already reached into the economies of scale. Therefore, the strategies for improving of port performances are required to survive against competition.

Nowadays, small and medium-sized earthquakes occur frequently in the west coast of Korea. The earthquake induced damages on the harbor structure such as quay wall possibly make a severe impact on national economy. Therefore, not only a seismic design for the structures but warning system for seismic damage right after the occurrence of earthquake should be developed. In this study, seismic fragility analysis was performed to be given to earthquake damage prediction system for quay wall structures in Busan and Incheon harbor. Four types of structures such as pier-type, caisson type, counterfort type, block-type were analyzed and fragility curves of functional performance level and collapse prevention level based on displacement criteria were found. Regression analyses by using the results of the two ports were done for possible use in other port structures.

프리캐스트 세그멘탈 교량의 3차원적인 선형관리를 수행할 수 있는 S/W로서 GEOCON이 개발되었다. GEOCON은 기본적으로 제작장에서 세그멘트 제작관리를 통한 선형관리를 실시하고, 그 결과로서 자동적으로 계산되는 제작선형은 가설시 선형관리에 활용된다. 본 논문에서는 실제 현장에서 나타날 수 있는 검측오차등으로 인하여 수치계산상으로는 마치 정확한 선형관리가 이루어지는 것으로 나타날 수 있는 상황들을 방지하기 위해 GEOCON에서 채택하고 있는 기술적인 특징들에 대하여 논하고 있다. 또한 실제 현장적용을 통하여 GEOCON의 효용성을 검증하였다. GEOCON을 통하여 선형관리된 부산항 배후도로 현장은 총 길이 2109m의 프리캐스트 세그멘탈 교량구간을 포함하고 있으며 고임판의 사용없이 허용 관리치 내에서 매우 정확한 선형관리가 이루어졌다.

The purpose of this study is to propose a ventilation corridor management plan to improve the thermal environment for Busan Metropolitan City. To this end, the characteristics of hot and cool spots in Busan were identified by conducting spatial statistical analysis, and thermal image data from Landsat-7 satellites and major ventilation corridors were analyzed through WRF meteorological simulation. The results showed the areas requiring thermal environment improvement among hot spot areas were Busanjin-gu, Dongnae-gu, industrial areas in Yeonje-gu and Sasang-gu, and Busan Port piers in large-scale facilities. The main ventilation corridor was identified as Geumjeongsan Mountain-Baekyangsan Mountain-Gudeoksan Mountain Valley. Based on the results, the ventilation corridor management strategy is suggested as follows. Industrial facilities and the Busan Port area are factors that increase the air temperature and worsen the thermal environment of the surrounding area. Therefore, urban and architectural plans are required to reduce the facility's temperature and consider the ventilation corridor. Areas requiring ventilation corridor management were Mandeok-dong and Sajik-dong, and they should be managed to prevent further damage to the forests. Since large-scale, high-rise apartment complexes in areas adjacent to forests interfere with the flow of cold and fresh air generated by forests, the construction of high-rise apartment complexes near Geumjeongsan Mountain with the new redevelopment of Type 3 general residential area should be avoided. It is expected that the results of this study can be used as basic data for urban planning and environmental planning in response to climate change in Busan Metropolitan City.
