As environmental problems accompanied by industrialization have emerged worldwide, solar and wind energy have entered the stage of commercialization, especially in Korea. In addition, research on improving aesthetics using solar cells is being actively conducted. Examples include developing a transmissive solar cell and developing a solar cell with flexibility and color. Therefore, in line with the upward trend of solar cell development and solar cell-based public facility installation, we will present guidelines for designing public facilities using solar cells to improve aesthetics. First of all, components were derived to increase the suitability of solar cell application through literature surveys on solar cells and case studies on public facilities using solar cells. Next, through prior research on public facility guidelines, we established evaluation principles and drafted design guidelines. Based on this, a Delphi survey was conducted on a group of experts to verify its validity. Design guidelines for solar cells application measures to improve the final public design aesthetics were derived. The goal is to improve the public facilities using solar cells, through Accessibility and cognition, Usability, Shape and aesthetics, Sustainability and energy efficiency, Continuity with the urban landscape. And it is expected that this data will be used to improve the aesthetics of public design using solar cells in the future.

Currently green growth and energy saving are major issues and solution using low-power LED lighting devices are gaining popularity. There are a few standards to control these LED lighting equipment and DMX512 protocol is a typical communication control standard used. DMX512 lighting control protocol is one of standard protocols widely used in various fields which include mainly stage lighting and landscape lighting. But in DMX512 protocol, line is to be connected to a wired connection. Advantage of wired connection is stable data transfer operation but it adds complexity and certain constraints as well in wired connection. To solve this problem, wired connection can be replaced efficiently with a wireless connection but for wireless, problem of data loss and two way communications arises. In this paper, these problems of wireless communication for DMX512 have been addressed and solutions for two way communications and data loss problem have been proposed.

This research is intended to suggest some reference materials for the future planning of floating hotel, by reviewing the concept of floating hotel and analyzing the realized and planned ones through the search of related documents and homepages. Floating hotel can be defined as a building for living/recreation/work/entertainment with floating system on water, but without navigation tool. In terms of sequence, the River Kawi Jungle Rafts Resort was built in 1976, Four Seasons Hotel in 1988, and Salt & Sill in 2008. Floating hotels are various in scale(height) and size(room numbers), and have basic, cultural, health & marina facilities. Architectural characteristics of sample facilities can be summarized as self-supporting of the facilities, environmentally friendly architectural planning, utilization of renewable energy, introduction of new plastic composite material, and provision of same view from all bedrooms by rotating the building.
