This paper describes on the selection of materials to reduce the environmental impacts and the role of the designer in the selction of the material in the design stage and the problems faced by the designers for environmental performance. For the designer it is a privilege of selecting material which is an integral part of the design. Today the main reasons for selecting materials in unscientific process are due to the lack of standards and not compatible contribution from the industry. So there is always a need for the production industries to establish a standard methodology which scientifically evaluate according to the perspective of environment credentials. In this paper through the comparison analysis it is to produce a better picture and indicate profits and shortcomings for the tools as a group; thus providing important cognisance for potential decision-makers as well as further research and development of this group of tools.

This study proposes a $CO_2$ emission reduction method through correlation analysis of a sample building. First, energy saving factors of heating, cooling, lighting were determined for the correlation analysis and $CO_2$ emission contribution rate of the design parameters have been analyzed. Then optimal combination of each design parameter has been drawn. Heat transfer coefficient of walls and windows, air permeability, windows area ratio, and shading devices were selected as applicable energy saving factors of the sample building. Also computer simulation was conducted using experimental design by Orthogonal Arrays of the statistical method. And the contribution rate was estimated by Analysis of Variance-ANOVA. As a result, the $CO_2$ emission in heating was reduced to 51.9%; in cooling to 16.8%; and in lighting to 2% compared to the existing building. The majority of the reduction was presented by heating energy.

This study is related with the energy saving of factory buildings, and automotive factory building are targeted for the study. Thus, energy saving strategies of factory buildings have been derived, being focused on automotive factory building, and then the energy saving factors that can be applied to the target factory buildings, have been selected. And then the energy consumption of heating, cooling and lighting, and total energy consumption have been calculated. Through this, the optimal combination by energy, has been derived and each integrated saving model has been proposed.

최근 들어 모바일 디바이스의 발전으로 인해 생성되는 데이터의 종류는 다양해지고, 양은 방대해지고 있다. 이렇게 생성된 방대한 양의 데이터를 빅데이터라고 한다. 빅데이터들은 기존의 데이터 처리 방법과 다른 방법으로 처리되어야한다. 빅데이터 처리의 대표적인 방법인 관계형데이터베이스시스템(RDBMS)와 NoSQL 방법 중 대표적인 방법인 MySQL과 MongoDB의 데이터를 모델링한다. 설계된 데이터를 바탕으로 보다 편하고 알맞게 데이터베이스시스템 성능평가를 수행한다.
