물발자국은 EU가 추진하고 있는 자원효율적인 유럽을 위한 로드맵(Roadmap to a Resource Efficient Europe)을 바탕으로 제시된 친환경제품 시장통합정책(Single Market for Green Product initiative)의 중요한 구성요소이다. 2014년 7월 EU 회원국의 주도로 물발자국 산정 국제표준(ISO 14046)이 제정되었으며 우리나라도 한국산업표준(KS I ISO 14046)으로 2015년 4월 부합화를 완료하였다. 국제표준(ISO 14046)에 기반을 둔 인증제도가 도입되는 경우, 기반을 갖추지 못한 인도, 베트남 등의 개도국에게는 수출시 무역장벽이 될 수 있으므로 우리나라는 이를 역이용하기 위한 전략을 수립해야 한다. 한편, 물발자국은 전과정평가(LCA)를 적용한 유사 발자국(예, 탄소발자국)인증과 비교할 때 국지적(Local) 환경영향을 고려하도록 되어 있어, 우리나라에서 생산 및 제조되는 제품들은 우리나라 수역에 미치는 영향을 고려해야 한다. 따라서 물발자국 산정방법은 국내외 호환을 위해 표준에 적합해야 하며, 우리나라의 물 환경을 고려하기 위해서 우리나라 적합한 물발자국 산정계수들의 도출이 필요하다. 이를 위해 이 연구에서는 국제표준을 바탕으로, 현재 국내 외에서 진행된 물발자국 산정연구를 검토하고 국내 기존 물 자원 관련 통계자료 분석을 통해 물발자국 방법론의 국내 적용 가능성을 확인하였다. The water footprint is an important component of the Single Market for Green Product initiative based on the EU's Roadmap to a Resource Efficient Europe. In July 2014, the EU has established the International Standard for Water Footprint (ISO 14046) and Korea has complied with the Korean Industrial Standard (KS I ISO 14046) in April 2015. If a certification system based on the international standard (ISO 14046) is introduced, developing countries such as India and Vietnam, which are not equipped with bases, can become a trade barriers in exporting, so Korea should establish a strategy to reverse them. On the other hand, water footprints are designed to take into account local environmental impacts when compared to similar footprints (eg, carbon footprint) using LCA, so that products manufactured and manufactured in Korea will have an impact on domestic waters Should be considered. Therefore, the method of the water footprint should conform to the standard for compatibility with other countries. In order to consider the domestic water condition, it is necessary to identify suitable indicator or factor for estimating water footprint on Korea. For this purpose, this study analyzed the water footprint estimation study conducted at domestic and foreign based on international standards and through the analysis of statistical data related to domestic water resources, we confirmed the applicability of the water footprint methodology in Korea.

As mentioned in Part I all groupware products have been categorized into three areas which include cooperation/document management systems(CMS), collaborative writing systems(CWS), and decision-making/meeting system(DMS). This study deals with a comparative analysis of the last two areas, which is added to the first. It turns out that DMS has a higher market share than CWS. However. since effective collaboration requires the functions inherent to these two systems. they should be integrated somehow. The systems' functions that have been implemented in response to design issues have been described. Each group of the functions has been divided into three parts which consist of basic function, quasi-basic function. and others. Such a decision has been made according to the frequency rate of the functions provided in the products. While the basic functions in CWS include collaboraive writing beyond restriction of time and place, group awareness. version control. and others, in DMS realtime collaboration. brainstorming. presentation. various task support. policy formation. document management, multimedia, subgroup communication. topic commenter, categorizer, screen capture and various rile transfer. The basic functions are merged into the integrated functional model which was proposed in Part I. Since the model is so flexible that it can partially include the quasi-functions in addition to the hasic functions. a large number of products may stem from the modification of the functional model.

The purpose of this study is to analyze the stress variation according to Hitler’s residence using EEG data. Hitler"s residence, one of the most monumental buildings, is designed as a grand and overbearing space, giving the visitor a sense of psychological pressure when moving from a high space to low space. Based on the above background, this paper constructs Hitler"s residence using virtual reality and measure the changes of the beta waves which are known to be related with stress when the floor level moves from high to low space in Hitler"s residence built in virtual space. The results of the experiment are as follows; when moving from high to low space, the subjects" stress was high and at the same time brain waves variation was increased greatly due to changes in space.

The purpose of this study is to implement an artificial intelligence-based real estate price estimation web using Tensorflow.js. Public data was used for data analysis, and insufficient data was collected using Web crawling techniques. An artificial neural network-based regression analysis is conducted to estimate the sale price of apartments. The analysis process and result data were visualized and presented. As a result, users were able to analyze data using deep learning without expertise and extract analysis process and result data.
