The sensor network technology for core technology of ubiquitous computing is in the spotlight recently, the research on sensor network is proceeding actively which is composed many different sensor node. USN(Ubiquitous Sensor Network) is the network that widely applies for life of human being. It works out to sense, storage, process, deliver every kind of appliances and environmental information from the stucktags and sensors. And it is possible to utilize to measure and monitor about the place of environmental pollution which is difficult for human to install. It's studied constantly since it be able to compose easily more subminiature, low-power, low-cost than previous one. And also it spotlights an important field of study, graft the green IT and IT of which the environment and IT unite stragically onto the Network. The problem for the air pollution in the office or the indoor except a specific working area is the continuously issue since the human beings have lived in the dwelling facilities. Measures for that problem are urgently needed. It's possible to solve for the freshair of outside with enough ventilation but that is the awkward situation to be managed by person. This study is the system engineering to management for indoor air condition under the sensor network. And research for efficiently manage an option.

This study analyzed directions of the energy product efficiency improvement and Carbon Tax for the domestic building sector. In order to analyze GHG reduction potential and total cost, the cost optimization model MESSAGE was used. In the case of the "efficiency improvement scenario," the cumulative potential GHG reduction amount - with respect to the "Reference scenario" - from 2010 to 2030 is forecast to be $104MtCO_2eq$, with a total projected cost of 2.706 trillion KRW. In the "carbon tax scenario," a reduction effect of $74MtCO_2eq$ in cumulative potential GHG reduction occurred, with a total projected cost of 2.776 trillion KRW. The range of per-ton GHG reduction cost for each scenario was seen to be approximately $-475{\sim}272won/tCO_2eq$, and the "efficiency improvement scenario" showed as the highest in the order of priority, in terms of the GHG reduction policy direction. Regarding policies to reduce GHG emissions in the building sector, the energy efficiency improvement is deemed to deployed first in the future.

Recently, the value and the status of the digital archives that are built individually in the crossroads of oblivion and memory are due to big data has attracted attention globally is confusing. Video data that contains the cultural memory of the digital archive, such as culture, art, life, society, and social conditions of the time, it is a cultural heritage of national common expressed. Also, it remains a trace of history from the various media just like magazines, books, painting, photography, and film. Digital archive system is one of the best research results of media convergence and it has also a good opportunity to take full advantage of the new opportunities and cultural assets. The collection of infinite information of big data in perspective transient that exist at the same time compatibility of big data, it is trying to dismantle the cultural memory of us. It was asserted that must meet the criteria which can correspond to via the new digital era, will be applied to preserve the traditional media. The current image archive is necessary to accommodate proper two different directions.

The purpose of this study is to contribute to enhancing spiritual combat power as the core of intangible combat power in Korean armed forces through analyses and suggestions on Admiral Yi Sun-sin's leadership for four major sweeping victories based upon jointness which effectively integrates tangible and intangible combat power in armed forces to maximize the synergy of fighting power. As our armed forces has improved their military structure in the dimension of hardwares so as to enhance their efficiency, according to the results of analyzing the process to promote the jointness between our armed forces and our allied powers in the dimension of softwares supporting such hardware dimensions, it was necessary to innovate the system for reinforcing future-oriented spiritual combat power as well as all the tasks related to leadership as the core of intangible combat power jointly and harmoniously. In order to derive tasks about the leadership of Korean armed forces in the dimension of softwares which should be combined with military structural reform for strengthening spiritual combat power for national defense, this study selected research questions linked with jointness. That is, (1) what is the core of military leadership in Western advanced countries in the age of jointness? (2) What are the contemporary illuminations or implications of Korean leaderships through Admiral Yi Sun-sin's war history? Then, this study analyzed literature reviews, this author's field interviews in the time of war participation, and leadership war history focusing on Admiral Yi Sun-sin's leadership for four major sweeping victories. According to the results of these analyses, this study extracted (1) the strategic leadership to predict and prepare the future, (2) the leadership of integration to create synergy effects, and (3) the leadership of knowledge to be practiced focusing on combats. In addition, in order to reinforce spiritual combat power based upon jointness, (1) it is necessary to precede in-depth and substantial leadership diagnosis for enhancing jointness. (2) It is necessary to embody national defense reform as well as integration for jointness improvement after scientifically comparing and analyzing the differentiation and integration between the Ministry of National Defense, army-navy-air force leadership centers, and PKO centers. (3) It is necessary to promote the merger and abolition between institutions related to intangibale combat power under the Ministry of National Defense.
