Seosan-Daesan Port is the sixth largest port in Korea, and it promotes port infrastructure expansion, regular route development, overseas marketing, and port incentive systems for continuous growth. In addition, the port is planning to open a regular car ferry line to Weihai, China. This study aims to provide useful research data for effective decision making by analyzing the feasibility of opening the Chinese (Weihai) car ferry route of Seosan-Daesan Port. Currently, some car ferry routes that operate between Korea and China are open at Incheon Port, the Port of Pyeongtaek-Dangjin, and the Port of Gunsan. In order to estimate the volume of cargo that will be created when the car ferry route from Seosan-Daesan Port to Weihai opens, this research analyzes the domestic cargo volume from the Chungcheongnam-do region, where Seosan-Daesan Port is located, to each of the regions where the other ports are located. We estimated the volume of cargo that can be transported on the car ferry from Seosan-Daesan Port to Weihai. As a result, by 2020, about 76,000 passengers and about 50,000 tons of cargo could be created. Suggestions were made for policy strategies that would revitalize passenger numbers and secure the cargo volume of the car ferry, along with a discussion of and the port incentive system.

Yeosu Gwangyang Port, along with Busan Port, Incheon Port, Ulsan Port, and Pyeongtaek Dangjin Port, serves as Korea's top five ports for trade on the southern coast. It is the second largest port in Korea after Busan Port, and the largest port in terms of import and export volume. Yeosu Chemical Industrial Complex, the world's largest chemical industrial complex, has continued to grow rapidly, but recently, the increase in volume has been decreasing. Therefore, this study sought to find major development strategies for the development of Yeosu Gwangyang Port and to derive the priorities of the strategies. To this end, the development strategy of Yeosu Gwangyang Port was divided into three major categories: operation revitalization, infrastructure construction, and policy support using the AHP analysis technique and analyzed again in two aspects: short, medium, and long term. As a result of the analysis, 'integrated operation of container docks and strengthening competitiveness' were considered the most important in short- and medium-term policies. It is believed that it will be necessary to integrate container operators, establish routes in preparation for entry of super-large ships, and install large cranes. In the long-term policy, the most important thing was to foster high value-added industries based on local industries. It is believed that strategies are needed to attract companies from outside regions through the settlement support system. The results of this study are expected to be used to establish development strategies for Yeosu Gwangyang Port and to establish investment priorities.

The significance of PNT information in the fourth industrial revolution is viewed differently in relation to the past. Autonomous vehicles, autonomous vessels, smart grids, and national infrastructure require sustainable and reliable services in addition to their high precision service. Satellite navigation system, which is the most representative system for providing PNT information, receive signals from satellites outside the earth so signal reception power is low and signal structures for civilian use are open to the public. Therefore, it is vulnerable to intentional and unintentional interference or hacking. Satellite navigation systems, which can easily acquire high performance of PNT information at low cost, require alternatives due to its vulnerability to the hacking. This paper proposed R-Mode (Ranging Mode) technology that utilizes currently operated navigation and communication infrastructure in terms of Signals of OPportunity (SoOP). For this, the Nationwide Differential Global Navigation Satellite System (NDGNSS), which currently gives a service of Medium Frequency (MF) navigation signal broadcasting, was used to validate the feasibility of a backup infrastructure in domestic maritime areas through simulation analysis.

In recent years, the development of GPS navigation system (GNSS), which has been developed not only by US GPS but also by major countries, is entering its final stage. It is time to change the infrastructure and technology system to correct each satellite system. To do this, we analyze the performance of the differential information provided by National Maritime PNT Office for GLONASS currently operating in its normal orbit, and present the its feasibility.

Tourism is one of the largest and fastest growing industries in the world, and is a major industry in many developed and developing countries. It is an increasingly important source of income, employment and wealth in many countries. However, its rapid expansion has also had detrimental environmental and socio-cultural impacts over many regions. Like tourism, the rapid growth in cruise tourism has also put greater pressures on environmental and cultural resources in cruise-ship ports of call. Through this paper, we would like to argue that more emphasis should be given to minimize national and international environmental impacts originated from cruise tourism with preparing infrastructures for sustainable tourism.

과거 3-4년 전까지 위성전파항법시스템의 백업 시스템으로 유일하게 논의되고 있었던 현실적 대안은 eLoran이었다. eLoran은 기존에 활용성이 낮아져 서비스가 점차 중단되고 있는 로란-C 시설을 개선하여 보다 높은 PNT 성능을 제공하도록 고안되었다. 기존에 로란-C 시설이 있는 국가나 지역에서는 위성전파항법시스템의 백업 시스템으로 eLoran을 효과적으로 확보할 수 있는 것이다. 그러나 기존 로란-C 시설을 이미 철거하였거나, 로란-C 시설을 가지고 있지 않았던 국가 입장에서는 eLoran을 확보하기 위해 로란-C 시설을 보유한 국가보다 더 많은 시설구축 비용이 필요하게 된다. 반면에 R-Mode는 현재 해상에서 활용되고 있는 전파신호를 이용하므로 신규 전파항법 인프라 구축에 따른 큰 투자 없이 적은 비용으로 위성전파항법시스템의 백업 시스템을 구현할 수 있다는 장점을 갖는다. 대한민국은 세계에서 유일하게 국가안보적 측면에서 GPS 전파간섭의 위협을 받고 있는 국가이다. 대한민국이 직면한 GPS 전파간섭은 해외에서 보고되고 있는 좁은 지역에서의 개인적 소규모 전파간섭과는 차원이 다르다. 특히 지난 2016년 3월 말, 우리나라는 약 엿새간 수도권과 강원지역 등이 동시에 GPS 전파간섭의 영향권 안에 든 바 있다. 이때 GPS 전파간섭은 과거에 발생한 GPS 전파간섭보다 더 넓은 지역에 영향을 주었고, 어선과 같은 소규모 선박의 조업까지 방해하는 피해를 안겼다. 본 논문은 대한민국이 하루 속히 해결해야 할 현안으로 인식되고 있는 위성전파항법시스템의 백업 시스템으로 중파 비컨 R-Mode를 적용할 필요가 있는지 논하고자 한다.

Because the existing BIM platform is based on user services, the focus is on the development of SaaS (Software as a Service), which provides business services online. However, since a harbor is a security facility, the harbor BIM platform is preferably provided in a private form, rather than relying on the infrastructure environment provided by external cloud providers. Therefore, this study analyzes and reviews the main functions to be provided as SaaS services of the harbor BIM platform. The goal is to build a cloud-based harbor BIM platform that can provide this service to users. To this end, we built IaaS (Infrastructure as a Service) environment of the harbor BIM platform based on the open source Open Stack and integrate and develop PaaS environment with Open Shift applied with IaaS. We applied the GPU to the harbor BIM platform to verify the performance of the harbor BIM platform, and found that the rendering and loading times are improved. In particular, it is expected to reduce the cost of introduction and provide it as the basic cloud environment of similar BIM platform for infrastructure facilities.
