On July 6, 2017, President Moon Jae - in attended the Hamburg G20 Summit in Hamburg, Germany, and presented the basic directions for North Korea policy through the Korean Peninsula Peace Initiative. In this paper, the Information needs of North Koreans are very strong, and the party Officials also listened to the fact that they listened to the North Korean broadcasting and watched the drama of South Korea. The broadcasting and communication sector aimed at enhancing the role of broadcasting in preparation for reunification in the light of the fact that physical contact can be excluded even in the presence of distrust of the North and the South. Therefore, it describes the cooperation plan through broadcasting against unification.

Effort to reduce energy consumptions or CO2 emissions is global trend. To follow this trend, spatial studies related to characteristics affecting energy consumptions or CO2 emissions have been conducted, but only with the focus on spatial dependence, not on spatial heterogeneity. The aim of this study is to investigate spatial heterogeneity patterns of CO2 emission based on socio-economic factors, land-use characteristics and traffic infrastructure of Seoul city. Geographically Weighted Regression (GWR) analysis was performed with 423 administrative district data in Seoul. The results suggest that population and employment densities, road density and railway length in most districts are found to have positive impact on the CO2 emissions. Residential and green area densities also have the highest positive impact on CO2 emissions in most districts of Gangnam-gu. The resulting model can be used to identify the spatial patterns of CO2 emissions at district level in Seoul. Eventually it can contribute to local energy policy and planning of metropolitan area.

Purpose: The purpose of this study is to analyze the economic ripple effect(ERE) of logistics industry by construction of Trans-Korea Railway (TKR) and present policy measures to minimize the economic loss of South Korea (SK). Research design, data and methodology: As the analysis method, exponential smoothing was used for demand forecasting, Input-Output analysis was used to estimate the economic ripple effect coefficient, and scenario analysis was used to an efficient way to invest in TKR to minimize SK's economic losses. Results: 1) the production(logistics fares) of TKR for 10 years after its completion is about 11.42 trillion won in positive relations, and 26.89 billion won in negative relations. 2) the ERE of SK in positive relations is 24.32 trillion won in production inducement effect, 8.1 trillion won in value-added inducement effect, 3.54 trillion won in import inducement effect, and 70,930 persons in employment inducement effect. But the ERE was insufficient in the negative relations. 3) SK's efficient investment method is providing materials and equipment by SK and building the TKR by North Korea in positive inter-Korea relations. Conclusions: For the successful operation of TKR, international cooperation, legalization and stable peace settlement on the Korean Peninsula are required.

With accommodation of a population of many young people and families due to Hangang River New Town Housing Project and development of railway station spheres, a need is increasing to improve the quality of public libraries service for Gimpo citizens and to establish more libraries. This study thus analyzed the book lending data of Gimpo City libraries, and the city's libraries-related social media big data in an effort to forecast the users, and thus to propose four library service improvement measures. First, in terms of book gathering and book development policy plans, a proposal was made to expand good books for children and youth, and to expand general original-language books related to learning of English, and English books for children. Second, in terms of the establishment of additional libraries or specialization strategy, a proposal was made to establish exclusive children's libraries or English libraries, and to establish library specialization strategy with a focus on children and English themes. Third, in terms of library culture programs, a proposal was made to provide library culture programs in relation to children education and to expand weekend library culture programs. Fourth, in terms of library facilities, considering the convenience of parking facilities, a proposal was made to establish libraries near apartment complexes.

As the Kyoto protocol and Bali road-map, our country is expected to be included to the emission reduction controlled country of greenhouse gas, so we are now urgent situation to take an action in the level of government. In this research, environment friendly rail logistics and combined transport were treated to meet with the green growth policy of our government. Major problems of Ui-wang ICD suggested in this research are short of yards, unutilized public CY, inconvenience use by non-share holders. It is necessary to improve rail logistic infrastructure, that is, additional expansion of yard, direct operation by KORAIL and regular unloading system are needed. such improvement can not be solved just by the endeavor of business body. Rail logistic infra & Integrated freight terminal has a tendency of SOC, which require tremendous amount of investment, so there are some limit in doing by private sector itself, now it's time to do by the government level. The improvement of rail logistic infrastructure in the level of government is possible by the policy of environment friendly green logistic support which is related with Logistic Policy Basic Law, so government should prepare detailed directives to activate Integrated freight terminal.

Recently mountain tourism has been promoted and introduction of railroads with utilizing mountain resources is being planned. With the government policies to increase the share of eco-friendly transportation on railroad, national double-tracking of single rail and improvement projects are on going. However, the eco-friendly railroad policy suggests the environmental impact assessment items only on air quality, water quality, geographical/geological features, fauna/flora, natural/environmental resources, noise/ vibration, and recreation/landscape. And for fauna/flora and natural/environmental resources, confirming the presence of environmental protection zone is enough to satisfy legal requirement. This study suggested to evaluate environmental/ecological values with quantitative data. Evaluation indices and evaluation items have been selected to provide the data. Each of the subject map and railroad network was overlapped. The study selected naturalness and diversity as major indicators and calculated weight values of the items under the indicators, which are to be usd for the selection of the sites for railway development. This assessment method could be applied to the environmentally friendly construction of railroads in the future.

In this paper the TRMS (Tilting Rolling-stock Maintenance System) that applies the concept of RAM (Reliability, Availability, and Maintainability) and RCM (Reliability Centered Maintenance) to Preventive and Corrective Maintenance Policy for TTX (Tilting Train Express) will be discussed. We will briefly introduce the RCM concepts and discus show these concepts and procedures are implemented in the TRMS S/W. In the TRMS S/W there are four modules, System and Operations Information Module, FMECA(Failure Modes, Effects, and Criticality Analysis)module, RAM Information Module, and RCM Analysis Module. The System and Operations Information Module provides the user interface for collection of systems and operations related data and the FMECA module provides a groundwork for the RCM analysis. The algorithms to calculate the reliability and failure rate for Weibull distribution and formulae to calculate the task intervals and task costs are proposed in the RAM and RCM Analysis Module respectively. There is a good possibility of applying RCM to other rolling stock maintenance systems if the benefit that RCM can brings to the maintenance world is fully recognized.

Due to the continuous expansion of the highway, the opening of the high-speed railway(KTX), etc, the demands of domestic air transport decreasing. In the circumstances, airports and local governments are spending themselves in taking a measure to activate local airports. In this aspect, this study seeks the smooth flow of human movement through the activation of Daegu International Airport by analyzing the present condition of Daegu International Airport in relation to the appearance of the high-speed railway, deducing plans for activating airports, and presenting the roadmaps for long-, mid- and short-term roles for the development of Daegu Airport, and Presents substantial fulfilling plans to secure the competitive power of Daegu International Airport by speeding up the flow of air goods of the area for the long run. It is suggested in the study that by setting up an organization exclusively responsible for activating Daegu International Airport in the city of Daegu, supporting local travel agencies to promote consistent demands, supporting aviation companies to employ Daegu International Airport as a major air base, establishing airlines with priority for airports that open newly in local cities of Japan and establishing and expanding airlines in China areas be promoted actively. Ministry of Construction & Transportation makes it a means of main airport Policy to only support Incheon International Airport to be a hub. However not only Incheon International Airport should be an amok representing the country, but also the wide Metropolitan area should supply the demands, and airports based in the West and East Coast areas need to be developed in the future. It is suggested that since air demands of domestic local airports are based on the demands of the of gin destination in neighboring region, multiple bases need to be developed. It is suggested that by developing not 1 in mega hub (Incheon International Airport) but 1 in mega hub. 2 in regional hub (the West and East Coast) and Jeju foy the tourism hub in our developing airports system.

It is over 12 years since the launch of Korea Train eXpress (KTX) services. Demand for the KTX has been on the increase continuously but few studies have been produced related to this phenomenon. KTX passenger demand has been constantly increasing due to influencing factors such as the expansion of network, rise of oil prices, etc. In this study, our main focus is to verify that there are other types of elements that are causing an increase in KTX demand; our approach looks at changes in social and psychological aspect that have occurred due to the reduction of travel time and cost, as well as the imposition of a five-day workweek. In other words, we considered diffusion theory in the marketing area, which affects product selection and purchasing attitudes, as a key factor that is causing passenger demand to increase. That is to say that it is hypothesized that the demand for travel on the KTX has increased due to the train's utility, which is spread by the diffusion effect Therefore, the Bass diffusion model was applied to explain the dramatic increase in KTX passenger demand. Based on this foundation, it was also discussed how certain marketing strategies that incorporate the diffusion effect should be considered variously for sustainable management of rail transportation, while considering a steady passenger demand.
