  • In this paper we present 3-D Navigation View, a three-dimensional visualization of indoor environment which serves as an intuitive and unified user interface for our developed indoor location tracking system via Virtual Reality Modeling Language (VRML) in web environment. The extracted user's spatial information from indoor location tracking system was further processed to facilitate the location indication in virtual 3-D indoor environment based on his location in physical world. External Authoring Interface (EAI) provided by VRML enables the integration of interactive 3-D graphics into web and direct communication with the encapsulated Java applet to update position and viewpoint of user periodically in 3-D indoor environment. As any web browser with VRML viewer plug-in is able to run the platform independent 3-D Navigation View, specialized and expensive hardware or software can be disregarded.

  • Photocatalysis is a photochemical catalytic reaction which is a highly promising tool for the environmental cleanup process. It is very effective in treatment of environmental pollutants by its unique redox property. It has wide applications in the treatment of atmospheric pollutants (e.g., nitrogen dioxide, trichloroethylene, volatile organics, hydrogen sulfide, benzene, etc) through oxidative removal and by disinfection (aeromicro flora). In this research, the fundamental aspects of photocatalysis are described with respect to the composition of catalysts, experimental conditions (e.g., temperature, duration, etc), and interfering factors (e.g., catalyst deactivation).

  • Eco-friendly architecture, generally speaking, is considered as the activity of planting more and designing ponds, therefore many clients and constructors prefer to avoid building so due to initial construction costs. This paper aims to examine the cognition of environmental equipment systems and the applicability of echo-friendly building constructions. We examined the designer's demands of building equipment systems and eco-friendly environment and tried to deduce desirable suggestions for the system. We should solve the fundamentals of economical problems in the construction of eco-friendly buildings and we better think that government should make it a policy to advertise it and to reform the taxation system regarding environment friendly buildings.

  • It has used buoy for efficient domestic farm operations and fishermen fish. Buoy uses IoT-based communication to transmit water temperature, salinity, humidity, wind speed, etc. to fishers in real time. In this paper, we utilize LoRa, which enables communication in the marine environment, to construct a network and apply it to an actual buoy for monitoring. The implemented LoRa uses the 900MHz band to configure the network. The sensor consisted of a sensor that can monitor the atmospheric environment and a sensor that can monitor the marine environment. In addition, the information received in real time will be provided to the fishing village host. The fishermen were fully aware of this and took appropriate measures to conduct sea trials.

  • [Purpose] Recently, skyscrapers have sharply increased throughout the world, including South Korea. Although a skyscraper has its own merit such as the landmark of a city, it also has various problems like massive energy consumption. This study is aimed to establish the concept of environment-friendly skyscraper and propose a plan to realize skyscraper after analyzing the architectural, facility and environmental friendly elements of skyscrapers. [Method] This study lists up skyscrapers over 40 floors and 200 meters high. Upon 10 constructed buildings, it analyzes their basic plans and the green building technologies applied to them and suggests effective and environment-friendly architectural plan. [Result] This study examined the distinctions of the layout, shape, facade, and floor plan plane of 10 skyscrapers and found out specific techniques to be used for the use plan of natural energy, plan for saving resources and reducing wastes and a plan for environmental architecture and system.

  • Regarding to the ecotourism for environmental conservation, tourists's consciousness and attitude on environment should be dealt with importantly more than the mass tourism. The purpose of this study is to identify the effects of the tourist's environmental consciousness on the ecotourism attitudes. As a result, it was analysed that the more people had interested in environmental problems, positive activities in the environment, the more people had the ecotourism attitudes. This suggested that for development of the ecotourism, it were needed to change tourist's attitude to friendly environment, to make higher consciousness about environmental conservation.

  • Nowadays environmental education is getting important. So, it is necessary to teach for students to realize the protection environment. Self-direct homepage was developed for 'Ecology & environment' environmental education. This homepage was made for sharing searched data and can be interactive each other on the internet. Therefore, in this study, environmental teaming was planned and practiced for high school 'Ecology & environment' class by e-PBL. Self-directed teaming, collaborative teaming and performance assessment are emphasized in the 7th educational curriculum. The PBL is efficient learning model for them. This study designed for a teaching and teaming method and strategies using PBL based upon the theories and practices. This study will also develop an e-learning. As a result, it is indicated that the teaching and learning method using PBL has the positive effects on learning that the development of self-directed learning and collaboration teaming Is observed by reflect journal and presentation of students. e-PBL is a teaming model for learning-centered that adapted many school and subject. Therefore e-PBL makes full use of be 'Ecology & environment' class and environmental education.

  • In recent days, it is usual case to extend the dwelling area to the balcony which is provided by service area. But the use of the extended area can be arisen discomfort with a view point of thermal environment by excessive heat accumulation in summer and excessive cold draft in winter. In this study, the skills were reviewed to improve the thermal environment of the extended area and evaluations were carried out. Additional heat supply by heat-convector installed at the lower end of the curtain wall can improve the thermal environment of the extended area and also arise surface temperature of the curtain wall surface. And aluminum plate installed under the floor could not improve the thermal environment but it was effective to shortening the initial heating time.

  • Environment friendly architecture, which will reduce shortcomings of current architectural culture, can be achieved by using natural energy and environment friendly building materials together with their environmental architecture techniques. Particularly, even though the overall building system is perfect, it cannot be considered as comfortable architectural space if the materials are polluted, harmful to human bodies and producing wastes. Therefore, in order to build environment friendly architecture, the selection of the materials is very important and necessary from the planning stage with careful reviews and concern. This study tries to define what the environment friendly materials we, to investigate and to classify them, in order to provide some guidelines for selecting them at plans to build. For examples, the materials can be classified into natural materials, continuously usable materials, recycled materials from wastes, and less polluting materials mixed with natural materials. Finally, this study reviews the existing products in the market and proposes to develop new ones in the future. It will present the circulation of resources in the 21century through recycled and reused materials.
