The KHCM procedure is a micro level analysis at signalized intersections requiring a lot of input variables and complex computations. The research was to investigate the possibility of simplifying the analysis procedures by using the generalized or the combined variables that less influence on the adjusted traffic volume and through-car equivalents of left or right turns. It was also tried to make lane grouping into directional flow ratio(v/s) based on a field surveys. The maximum and minimum values of each variables were compared with each other through the KHCM analysis procedures in terms of control delay. The lane grouping and the synthetical influence of a simplified method was evaluated with the scenario built in prevailing maximum and minimum conditions. The study showed that the control delay was not significantly sensitive to the selected variables and the lane grouping and their synthetical influence as well.

This study aims to estimate the values of freshwater ecosystem services from demand and supply perspectives. From demand side, unit-values of ecosystem services are derived from Environmental Valuation Information System (EVIS) and aggregated to 5 main watersheds in Korea. The derived unit-values are based on the willingness to pay estimates per household from stated preference methods. The nation-wide average total values of water quantity supply, water purification, and natural disaster control are estimated as 501.2, 410.4, and 242.4 billion won/year, respectively. From supply side, we examine the direct and indirect public expenditures (or investment) in 2013 to improve freshwater ecosystem services by the government. The total sum of government expenditures corresponds to 8,882 billion won in 2013, where 12.9, 81.3, 0.3 and 5.3% are spent to improve provisioning, regulating, supporting and cultural services, respectively, indicating that most efforts are concentrated in enhancing regulating services.

The important of Smart City has been increasing on the driving force of 4^th industrial revolution and method to solve urban problems. Korea government introduced and implemented ubiquitous City as an intrinsic Smart City brand from the early 21^th century. Diverse types of Smart City projects were announced as national strategy by the spatial characteristics. National Test-Beds in Sejong city and Busan(EDC: Eco Delta City) are urban planning to be future city models for new town development. In the old towns in cities, various type of Smart City projects are support by government by urban growth stage; frontiers, stable or declining urban realm. 「3^rd Comprehensive Plan for Smart City(2019 ~ 2023)」 in Korea plans an important role to build innovative ecosystem and reinforce global competiveness by spreading of Smart Cities. For the successful Smart City as open and inclusive space, it is need that this space should be made by the cooperation of citizens, private sectors and local and central government.

Through the Broadcasting Act, Republic of Korea regulates the broadcasting system to remain neutral regarding particular party or candidate. However, as MBC and JTBC reports the issue of President Park's impeachment in bisected way - conservative and progressive - the controversy aroused. This research paper comparatively analyzed each broadcasting company's evening news by focusing on quantity aspect, reporting tendency regarding trend of public opinion and mass rally and the news frame. Our research showed that both JTBC and MBC had partially reported; JTBC on pro-impeachment rally's side which was called candlelight rally, and MBC on anti-impeachment rally's side, called Korean National Flag rally. Regarding the way how they reported the impeachment, JTBC reported much more in depth than MBC, and MBC reported the process emotionally, standing for President Park.

Recently, the social issue about harmful effects of nano-materials including nano-products to human body and environment have been raised, which were not expected in times past. To prevent the risks of nano-materials on the environment and human body, the regulatory policies are reinforced to ensure public health in world trends. In Korea, governmental department has prepared the policy for 'National nano-safety Management Master Plan' since 2011. However, it is very hard to manage all kinds of nano-materials, due to lack of nano-safety law and a wide range of nano-technology application. This study aims to analyze the current situation of the national policy related to nano-safety management and legislation, and also review the limitation of current system to propose improvement plan for nano-safety.

Algorithm which can analyze the slope failure behavior utilizing the comprehensive information of the dense point of joint poles and the joint set orientations, both of which are obtained statistically, and the defect pattern of pole distribution has been developed. This method overcomes the potential incorrectness of the hemispheric projection method utilizing the joint set orientations only and also enhances the reliability of slope failure analysis. To this end a method capable of calculating the joint dispersion index directly from the joint pole distribution, instead of contour map, has been devised. The representative orientations for the slope failure analysis has been determined by considering the number and orientations of cone angle-dependent joint sets as well as the joint dispersion index. By engaging these representative orientations to the hemispheric projection analysis more reliable slope failure examination has been carried out. Sensitivity analysis for the potentially unstable slope of plane failure mode has been performed. Significance of joint strength index and the external seismic loading on the slope stability has been fully analyzed.
