Domestic and international energy and eco-friendly companies take advantage of social media for image enhancement and product promotion. However, there were no in-depth empirical analysis to verify specific effectiveness of social media use in these sectors. The purpose of this study is to reveal the key factors that are considered to use social media effectively for energy and eco-friendly companies. For this purpose, we regarded the effectiveness of social media as Post Awareness and Word of Mouth. Characteristics of social media as a medium were measured separately, media richness and media genre, as independent variables of social media effectiveness. We investigated 413 posts in Facebook brand page of energy and eco-friendly companies and conducted a content analysis. As a result, post awareness of users was greater when post has richer media such as video. For media genre, word of mouth appeared to be greater when the posts provide information.

Many project (such ESCO or BRP) are being implemented for existing building energy saving. Most of medium or large building that use many energy being implemented this project. In the case of large or medium building must implement obligatorily Energy auditing. Therefore, They can be recognize their building energy consumption situation. But, In the case of small building don't need obligatorily energy auditing. Therefore, They can't be recognize their building energy consumption situation. As a result, Small buildings are difficult to participate in energy efficiency retrofit. In this research, Building owners of buildings energy load recognition and energy efficiency retrofit possible participation was analysis though survey. Survey results, Most building owners don't know building energy load. But they have a good mind to retrofit building energy efficiency. As a result, If they have energy load information, they will be participate energy efficiency retrofit.

This study explored and described the living spiritual experience and was attempted to gain an understanding of spirituality. This was done by eliciting participants′ verbal descriptions of their experiences. Method: Data was obtained from in-depth interviews with one cancer patient, one pastor, and three missionaries after obtaining informed consent from each. Interviews were tape recorded and transcribed verbatim. The transcripts were analyzed using Colaizzi′s phenomenological method. Sandelowski′s evaluation criteria for qualitative research, such as reliability, suitability and auditability, were also used to establish reliability and validity of this study. Result: The five major theme clusters that designated the essence of the spiritual experience, "spiritual awareness," "interconnectedness," "love," "tran- scendent energy," "purpose and meaning in life," emerged from the analysis. Conclusion: This study revealed that spirituality was activated by awareness through introspection and interconnectedness with a Supreme Being. The interconnectedness with a Supreme Being played an important role in harmonious relationships with others and self. It also resulted in revealing the other beneticial attributes of spirituality. Love, the core concept of the interconnectedness, worked as a transcendent energy. Also, the ability to see beyond reality and resulted in finding meaning in life and accomplishing well being.

The purpose of this study is to survey and analyze the environmental awareness and attitude of elementary school students, adapting the CHEAKS(Children's Environmental Attitude and Knowledge Scale) for Korean elementary students, which is the valid-tested tools for children's environmental awareness and altitude. The subjects are 580 students from 6 elementary schools. The differences of the environmental attitude are surveyed and analyzed by environmental education activities, such as environmental activities in school and “the school forest movement”, and environmental awareness and concern. The results are as followings: First, the subjects replied that the environmental problems are very serious, such as atmospheric pollution(37.6%), water pollution(22.2%) and food waste(16.3%), but they are relatively optimistic of the future environment. Second, the verbal commitment subdomain and the affect domain are evaluated higher than the actual commitment subdomain, and the environmental issues of water, energy and recycling are considered more importantly than other issues such as environmental generals, pollutions and animals. Third, the grade and the sex have little effect on the environmental attitude, but the environmental education activities have great positive effect, such as the experience of environmental camping, the education of saving resources, waste separation and the experience of raising plants and flowers. Fourth, the students with high awareness and concern about the environmental problems have high environmental attitude. Especially, the awareness and concern on the flowers and plants have very strong correlation with environmental attitude, regardless of the subdomains. Finally, the students from the school participating “the school forest movement” have relatively positive environmental attitude. Particularly, the participation of students and the positive approach of the school have positively great influence on the students' environmental attitude in all of 3 subdomains and 6 environmental issues.

In this paper, we design a middleware for context-awareness which provides compound contexts from diverse sensors on a mobile device. Until now, most of context-aware application developers have taken responsibility for context processing from sensing data. Such application-level context processing causes heavily redundant data processing and leads to significant resource waste in energy as well as computing. In the proposed scheme, we define primitive and compound context map which consists of relavant sensors and features. Based on the context definition, each application demands a context of interest to the middleware, and thus similar context-aware applications inherently share context information and procesing within the middleware. We show that the proposed scheme significantly reduces the resource amounts of cpu, memory, and battery, and that the performance gain gets much more when multiple applications which need similar contexts are running.

With the long-term use of fossil fuel, the whole world is suffering from serious abnormal changes in weather caused by global warming. For this reason, many countries are reducing greenhouse gas emissions out of obligation and the allowable emissions are assigned to each country. Korea is also putting much effort into reducing greenhouse gas emissions by 30 percent against BAU(Business As Usual) by 2020, and is pushing ahead with several projects such as 'Million Green Home' and 'Hatsal Gaduk Home' to expand the use of new renewable energy in house as part of its policy. This study was designed to come up with improvements and help to expand photovoltaic facilities, by investigating and analyzing the current state of photovoltaic facilities in the country and problems in installing them through an in-site reconnaissance and a survey in Jecheon area. As the result, it was found that residents in the area were inadequate to operate and install photovoltaic facilities, lacked awareness of them and felt burdened economically by managing and installing them, although they had a high awareness of solar energy and photovoltaic facilities are constantly increasing with governmental support. In conclusion, it is considered that as improvements, operational effects should be increased through development of techniques, factors to reduce the effects in operating them due to insufficient management and installation should be removed and awareness of residents need to be improved through long-term plans, political support and education of the government.

Awareness of resource conservation and pollution prevention has been continually increasing. The proven benefits from CFRP's unique combination of light weight and high strength compare to conventional material is well suited for minimizing fuel consumption during vehicle in particular rail operation. Responding the awareness, this work intends to study CFRP's recycling method that is not only technical performance but also environmental view point. According to prior work of technical performance test, this work aims at quantifying the footprint of energy and GHG derived from the two appreciated performance of pyrolysis and acids recycling methods. The streamline LCA is the concept for systematic assessment. The boundary is scoped at the recycling activity, consequently, the data in and out from the specific target activity are obtained under the gate to gate data collection. Its function is recovery carbon fiber. To count and compare function, functional unit is set at 60% of recycling rate. Korea database is mainly source for acquiring the footprint of both. The numerical results presented that the energy footprint of acids and pyrolysis is 164.95 and 1,199.88 MJ-eq., respectively. Meantime, the GHG footprint of is 1,196.22 and 5,916.08 g CO2 eq. for acids and pyrolysis. In summary, the acids recycling method is, in regarding the environmental performance, better than pyrolysis recycling method.
