Grounwater level applied on dredged and reclaimed clay layer was assumed to be the same value under design criterion as field test one, but actually differences are found through the monitoring test. In this study, a case study of measuring residual groundwater level is performed in ground improvement construction of Gwangyang container terminal and hinterland. With priority given to residual groundwater level measured during construction and management period of 9 years, it is investigated that residual groundwater level (R. GWL) could be applied reasonably to the design, construction, and use stages of the container harbor and land development.

진해 용원 인근 해역은 부산신항 개발사업으로 추진된 북컨테이너부두 조성사업 및 항만 배후 단지 조성사업으로 전면 해역이 매립되어 원활한 해수흐름이 차단되었고, 인공적인 해양구조물 및 시설물로 인해 해안선 지형 및 단면 변화가 발생하고 이로 인해 수역의 해수순환이 점진적으로 변화하는 지역이다. 인근 어판장으로의 선박의 출입이 차단되면서 발생된 민원으로 인해 송정천 하구 지점의 북쪽 통로를 이용한 선박이동만이 가능한 좁고 긴 수로형태를 가진 폐쇄성 수역으로 변형되었다. 한국에서는 찾아볼 수 없는 이례적인 형태의 용원수로는 폐쇄성 수역이 형성되면서 수로 내로 유입되는 오염물질은 수로 내에 체류되어 수질을 악화시킬 수 있다. 이러한 폐쇄성 수역이 형성되면서 발생하는 다양한 수질영향을 장기간 평가하는 것은 매우 중요하다고 볼 수 있다. 이에 본 연구에서는 용원수로의 시 공간적인 수질변동 양상을 분석하기 위해 2003년부터 2017년까지 선정된 수질측정 지점에서의 주요수질항목에 대한 수질분석을 실시하였으며, 용원수로로 유입되는 토구를 전수조사하고, 비강우시 및 강우시 토구 모니터링을 통해 육상에서 기인하는 오염원을 분석하였다. 또한, 용원수로 내에 유입된 오염물질 거동 분석을 위해 추적자 실험을 통해 용원수로로 유입된 오염원 거동을 예측하여 용원수로의 수질변화 분석에 대한 연구를 실시하였다.

This research examined the mediation effect of Workforce Agility (WA) on the relationship between environmental uncertainty and operational performance. We manipulated the control variables that are known to be affected by employment flexibility. Employment flexibility is caused by idiosyncratic characteristics of Korean port system. The analysis was tested by Baron & Kenny's method. The result indicates that each path of the proposed model is significant. Furthermore, the mediation effect was checked with the Sobel Test. The research revealed that environment uncertainty poses an indirect effect on operational performance. Both supply/demand uncertainty and technological uncertainty affected operational performance through the mediation effect of WA. Most of the distribution centers located in Busan Newport Distripark are operated in a bimodal labor (human resource) system which includes both permanent employees (workers) and temporary employees (workers). This empirical research provides theoretical and managerial implications by suggesting ways to increase efficiency in distribution center operation through WA enhancement, and to improve the unloading labor system.

This study assesses Incheon Metropolitan City's potential as a global logistics hub amid intensified competition since the 2000s. Utilizing Importance-Performance Analysis(IPA), it evaluates competitive factors for logistics hub cities and Incheon's current positioning. The research identifies world-class infrastructure development and global city connectivity as key competitiveness factors. While Incheon, with its international airport and port, currently functions as a logistics hub, areas for improvement emerge. Recommendations include developing specialized cargo infrastructure for cold-chain and e-commerce, expanding the global network through multimodal transportation, and addressing gaps in smart and eco-friendly logistics. These suggestions encompass professional training, information platform establishment, and sector-wide decarbonization initiatives. The study's significance lies in its IPA-driven evaluation of competitiveness factors and Incheon's status, providing actionable recommendations for strategic planning to enhance the city's position as a global logistics hub.

In this study, the in-situ model test has been conducted and used to estimate and analyze consolidation behavior of the ground by using the miniature test that reconstructs economically geotechnical behavior of in-situ full scale structure. To analogize the relation among effective stress, void ratio and coefficient of permeability at the self-weight consolidation stage, the low stress seepage consolidation test has been conducted and the involution function of constitutive equation had been obtained from the result of the curve fitted seepage consolidation test result. As a result of the numerical analysis that had been conducted on the representative section using a constitute equation, final settlement was similar with those of self-weight consolidation of the centrifugal model test. But, it was more or less smaller. It seems that these trends are caused by the difference between estimated values.

진해 용원해역은 부산 신항 개발사업의 일환으로 추진된 북 부두조성 사업 및 항만 배후단지 조성사업으로 전면 해역이 매립되어 원활한 해수흐름이 차단되고 송정천 하구 지점의 견마도 북쪽 통로를 이용한 선박이동만이 가능한 좁고 긴 수로형태로 변형된 국내에서 이례적인 폐쇄성 수역으로 변형되었다. 용원수로의 평균 너비는 약 100 m, 길이는 3,600 m정도로 세장비가 아주 큰 수로에 해당되며, 용원수로의 조석 유입유출은 뚜렷한 일차원적 흐름으로 간주할 수 있으며 입구에서 용원수로 내부로 갈수록 조석유입은 점진적으로 감소하여 흐름이 정체되는 양상을 보이고 있다. 이로 인한 지형적, 물리적 특성 때문에 외해와의 해수교환이 제한되어 적은 양의 오염물질이 유입되어도 유입부하가 지속될 경우 수로 바닥에 축적될 가능성이 매우 크며, 이는 수질에 대한 악영향을 끼칠 수 있다. 따라서 폐쇄성 수역인 용원수로를 장기간 모니터링하고 수질에 끼치는 영향을 파악하여 적절한 관리방안을 마련하는 것이 중요하다고 볼 수 있으며, 본 연구에서는 과거 축적된 수환경 자료와 실제로 용원수로 내에서 측정된 자료들을 기반으로 수질변화에 대한 시 공간적인 양상을 분석하였다. 또한 용원수로로 유입되는 토구를 전수조사하고, 강우시와 비강우시 토구 모니터링을 통해 육상에서 기인하는 오염원을 분석하였으며, 용원수로 내에 유입된 오염물질 거동 분석을 위해 추적자 실험을 실시하였다. 특히 용원수로 내 오염도가 높은 내측지점에서 추적자 투입하여 드론 영상을 통해 그 거동을 분석하고, 수로 내로 유입되는 오염원을 조사하여 폐쇄성 정체수역에서의 수질영향을 분석하였다. 이를 바탕으로 용원수로 내 수질영향에 대한 관리방안을 모색하고자 하였다.

Wave overtopping rate is one of the most important design parameters for coastal structures. In this study, the physical model tests for measuring the wave overtopping have been conducted with the foreshore slope in front of the seawall. The bottom seabed for the coastal road area was fabricated at the wave flume for two areas in the East sea areas. The wave overtopping rate was measured for various water depths and wave conditions in each coastal area. In particular, the impulsive wave conditions were compared with the previous research and the similar trends of wave overtopping was observed. It could be known that the effect of foreshore slope was significant and should be concerned for applying theses formula like EurOtop.

The primary purpose of this study is to examine empirically the effect of foreign crew's cultural and organizational characteristics on their self-efficacy and organization commitment. Currently, the restrictions on the employment of the foreign crews are being eased in the Korean shipping industry and many problems are occurring consequently. However, specific and empirical studies on the relevancy of cultural characteristics to the crew's self-efficacy and organizational commitment on board the vessels with combined crews have not yet been carried out. To solve these problems, we examined how the cultural characteristics such as acculturation and accommodation of different culture related to the improvement of cultural homogeneity of vessels with combined crews influence on the self-efficacy, job satisfaction and organizational commitment of the foreign crews through SEM analysis. According to the results, hypothesis 1 and 2 were all supported with statistical significance. To conclude, this study suggests that foreign crew's cultural homogeneity and their self-efficacy should be firstly enhanced in order to improve organizational commitment on the vessel with combined crews. Furthermore, a study on self-efficacy of crew organization is urgently needed to enhance the effectiveness of an organization in a vessel with combined crews that has special environment. The result of this study will contribute a lot to the organization management of a vessel with combined crews.

The reclaimed land has peculiar characteristic of nature environment unlike midtown or inland and also, in comparison with inland, has bad weather condition, such as low temperature, strong wind, excessive sunshine, and moisture involved in a salt. Therefore the case of developing water front needs understanding characteristic of weather environment mused by reclamation in detail and proper development and organized maintenance. If development which doesn't investigate topographic and climate characteristic sufficiently is drove ahead, a rise of expense for energy and maintenance is going to be mused by deteriorating weather environmental, occurring a flaw of facility and calculating inaccurate capacity of facility. We looked into the weather state and drew up the standard weather data of the newport area in Busan which is reclaiming and developing now. In this research at the base qf the standard weather data, we calculate the dynamic peak loads for commerce, business and residence and then we utilize the results of the load calculation as basic information to determine facility capacity in the rear city of the newport area.
