This article indicates grounds of establishing the plan, characteristics and problems of the plan. Following is the principal contents which are treated in the article; 1st, strategy of constructing opened and combined land axis, 2nd, competency intensifying strategy by areas, 3rd, constructing health and pleasant national environment,4th, strategy for organizing express transportation and information network through the whole land, 5か, special features related building basis of cooperation interchange between North and South Korea. In the conclusion, although there were some problems through 3 times national comprehensive planning, this plan should be helpful to develop nation keeping balance for which construction and preservation would be harmonized appropriately.

Many of logistics-related research in automobile industry has focused on inbound logistics and procurement. Research into outbound logistics is relatively few. As a starting research into outbound logistics in automobile industry, this paper examined its logistics network problems with three aspects - location strategy, inventory strategy and transportation strategy. We proposed alternatives of logistics network design resolution, and presented three practical scenarios based on those alternatives. Based on interview, on-site visit and internal data collection processes, we identified major domestic outbound logistics problems such as redundant logistics bases, inefficient delivery policy, insufficient inventory capacity, inventory stock quality deterioration, inefficient transportation system, and etc. In order to cope with those problems, we proposed such strategic alternatives as introduction of hub-and-spoke system, integration of logistics bases, introduction of (automatic) parking building, diversification of transportation mode, and etc. At the same time, we constructed three practically executable scenarios based on those ideas. The first is "Center Hub" scenario, the second is "Metropolitan Hub" scenario. The third and last scenario is "Regional Consolidation of Warehouses (distribution centers)".

In this paper, I applied grounded theory in exploring how Twitter became the battlefield for China's public diplomacy campaign. China's new move to global social media platforms, such as Twitter and Facebook, has been a controversial strategy in public diplomacy. This study analyzes Chinese Foreign Spokesperson Zhao Lijian's Twitter posts and comments. It models China's recent diplomatic move to Twitter as a "war of words" model, with features including "leadership," "polarization," and "aggression," while exerting possible effects as "resistance," "hatred," and "sarcasm" to the global community. Our findings show that by failing to gage public opinion and promote the country's positive image, China's current digital diplomacy strategy reflected by Zhao Lijian's tweets has instead constructed a polarized political public sphere, contradictory to the country's promoted "shared human destiny." The "war of words" model extends our understanding of China's new digital diplomacy move as a hybrid of state propaganda and self-performance. Such a strategy could spread hate speech and accelerate political polarization in cyberspace, despite improvements to China's homogenous network building on Twitter.

BIM could be used for integrating project information through life cycle of building facilities. Also it could improve the accuracy and work efficiency through data interoperability with other disciplines. However, these benefits from adopting BIM could not be attained easily in real project cases. In order to make the most use of BIM and get the maximum benefits from it, the environments such as standards, guidelines and the related technologies are also could be supported. Therefore many countries are developing or already developed the technology roadmap for BIM. In this study, we tried to analyze the BIM technology status and develop the strategy for improve usability of BIM in Korea.

As eco-friendly and sustainable architecture is becoming more popular, the interest in Korean traditional wooden buildings (Hanok) has also been increasing. The building technologies of the wooden construction have been actively developed in all over the world through the diversification of new materials and construction methods. On the other hand, the growth rate of wooden construction market is still slow in Korea. In an attempt to promote the Korean traditional wooden buildings, a comprehensive research project has been conducted. This R&D project is developing standard designs, new materials, and methods for modernized Hanok including houses, public buildings, long-span structures, and even high-rise buildings. To this end, the purpose of this study is to formulate a technological strategy for popularization of modernized Hanok. Influencing variables and issues are analyzed and defined first. At the same time, the five keywords have examined in the perspective of dissemination of modernized Hanok technology. Finally, a technology road map for strategic development of modernized Hanok is proposed through casual diagrams.

The Ministry of National Defense of the Republic of Korea is showing a lot of interest in net zero-energy buildings (NZEBs) to reduce energy consumption of military facilities and to promote green growth policy in military sector. The application of building passive technologies and renewable energies is essential to achieving NZEBs. This paper analyzed energy performance and energy cost on the conventional heating and cooling system (baseline scenario) and three different alternative scenarios (ALT 1, ALT 2 and ALT 3) applied in a hypothetical military building. A building modeling and simulation software (DesignBuilder V6.1) with EnergyPlus calculation engine was used to calculate the energy consumption for each scenario. Overall, when the GSHPs are applied to both space airconditioning and domestic hot water (DHW) production, Alt-2 and Alt-3, the amount of energy consumption for target building can be greatly reduced. In addition, when the building envelope performance is increased like Alt-3, the energy consumption can be further reduced. The annual energy cost analysis showed that the baseline was approximately 161 million KRW, while Alt-3 was approximately 33 million KRW. Therefore, it was analyzed that the initial construction cost increase could be recovered within about 6.7 years for ALT 3. The results of this study can help decision-makers to determine the optimal strategy for implementing GSHP systems in military buildings through energy performance and initial construction cost assessment.

Remodeling for an aged building is emerging as a potential alternative towards the future of the building industry. It is a more effective method than the new construction in environmental friendly view. Most of remodeling were aimed at the improvement of the function of the deteriorated finishing materials. But, at the early stage of remodeling process, energy performance of a building can be improved by adopting passive design solutions such as daylighting and natural ventilation. The purpose of this study is to explain the passive design strategy in remodeling process and to suggest a application of LT method. LT method is an energy-design tool which responds to parameters available early in design development. It provides an output of annual primary energy for lighting, heating, cooling and ventilation in non-domestic buildings. LT method basically uses the concept of passive zone and non-passive zones and should be used to evaluate the energy performance of a number of options and to make comparisons. In this paper, the process of LT method is introduced and investigated an applicability in our office building.
