Although assessing outdoor environment and green space in terms of sustainability and environmental performance is perceived as an important issue, most existing green building certification systems are more focused on buildings and indoor environment. Recently, the Sustainable Site Initiatives (SITES) has been developed by American Society of Landscape Architecture in order to evaluate sustainability of site development and outdoor environment. Separate from LEED, the SITES are increasingly receiving attentions as a reliable certification system in the United States. As a preliminary study to develop the items of outdoor environmental assessment, the present study is purposed to analyze the assessment items, grading system and applicability of SITES for better understanding on the system. Also it was compared to existing green building certification criteria, including G-SEED, LEED-NC, and LEED-ND in order to investigate similarities and discrepancies. The results would provide insights and basic data to improve assessment items for outdoor environment of G-SEED.

United Nations Framework Convention on Climate Change(UNFCCC), an international treaty to prevent the regulation and global warming, has passed through the General Assembly for 17 times from 1992 to 2011. To create a performance plan specific, such as the Kyoto Protocol, it is to promote the reduction of energy consumption and greenhouse gases worldwide. In South Korea, Korea Infrastructure Safety and Technology Corporation(KISTEC) is working and supporting for developing method of green remodeling policy. Among several solutions, "Remodeling" ensures to increase the energy efficiency of buildings and to reduce the emissions of greenhouse gases, and consequently it could maintain buildings high efficiency. For remodeling projects, it is most important to determine construction plan including remodeling scopes and methods, while the plan has been determined by the engineer's background and experience. Therefore, this study aims at developing a method for selecting optimal skin system which has remarkable influence to energy performance of the buildings.

The United States is constructing Missile Defense System to defend from elevated ballistic missile threat of Russia, China and North Korea. U.S. MD system is consists of IAMD concept by MDA centralized, and U.S. Navy takes charge detection, tracking and intercepting on the sea. In this paper, it is reported that concept, current state and plan of U.S. Navy Aegis Ballistic Missile Defense.

Artificial intelligence and robot technology have been received attention as core technologies of the 4th industrial revolution. This paradigm change of science technology raises the importance of unmanned technology field. This paper categorizes unmanned technology as unmanned ground system, unmanned maritime system, and unmanned aircraft system, And it analyzes 557 cases of open patents and classifies each sort of specific technology elements. After then patent information, which were classified by technology, by patent assignees, and by IPC codes, covers unmanned technology maturity, development direction of research and core technology trends. This research provides directions of unmanned technology research and diverse field technology development through cooperation with various perspectives of quantitative analysis of patents.

On the internal based search, the big data inference, which is failed in the president's election in the United States of America in 2016, is failed, because the prediction method is used on the base of the searching numerical value of a candidate for the presidency. Also the Flu Trend service is opened by the Google in 2008. But the Google was embarrassed for the fame's failure for the killing flu prediction system in 2011 and the prediction of presidential election in 2016. In this paper, using the virtual vote algorithm for virtual election and data mining method, the election prediction algorithm is proposed and unpacked. And also the WEKA DB is unpacked. Especially in this paper, using the K means algorithm and XEDOS tools, the prediction of election results is unpacked efficiently. Also using the analysis of the WEKA DB, the smart election prediction system is proposed in this paper.

A performance-based design of smoke management systems for semiconductor fabrication facilities is described in this paper. The example of one such facility is discussed. Performance criteria for smoke control systems were established, effective smoke removal system features were identified and optimal system exhaust capacity requirements were developed by applying engineering tools including Fire Dynamic Simulator model. Considering the fact that the absence of relevant design guide, codes for consensus standards for semiconductor smoke design in Korea and United States this performance based approach can and should be applied to other fabrication facilities designs.

Construction industry is the biggest employer as a single sector, however, that needs better job quality and working conditions due to problems such as lack of job stability, aging worker, late disbursement of wages, and so on. In order to deal with fundamental issues of construction skilled worker's wages, this paper performs comparing the wage system of the construction industry in South Korea and the United States, and analyzes the characteristics about wage structure and determination. As a result of this study about U.S. case, it requires all stakeholder's exertions through technical competitiveness and management ability, not price war by reducing laborer's wages.

Railway signal interlocking device with the reverse unit control device which is most important from country season, the subway and the high-speed railroad back, electric relay boarding and lodging accomplishes the master and servant and it comes and before from the Japanese back and an electronic interlocking device, a zone one interest in updated technology introduction Great Britain, Germany, Sweden and the United States, it quarrels about under developing it puts to practical use even from our country it shows. About reasoning lower our country subway or the country closing up shop stem there is not a possibility of throwing away the impression where the exhibition hall of foreign nation signal system is being turning out. Consequently is enormous a system well expense at the foreign corporation about under paying Oh!, it understands, with difficult always it is exposed to it is an actuality in the accident which is dangerous. In like this point of view first piece which is important securing safety of system from electronic anger of electronic interlocking device.

The Republic of Korea has a close cooperative relationship with NATO, of which the United States is a member. NATO is encouraged to follow UHF coalition waveforms for military air operations(SATURN) as defined in STANAG 4372. SATURN is a high-speed frequency hopping waveform with enhanced anti-jamming and security functions. Plans to improve the performance of existing military aircraft with air to ground radios to which SATURN function is applied. IFF case analysis and MRT evaluation plan were established to present an efficient test and evaluation plan for air to ground radios.
