  • This study investigated how external environmentally-friendly factors adopted to improve the quality of outdoor spaces have been designed and used in the construction of apartment complexes. The goal of this study is to determine what areas should be improved through environmentally-friendly ways to create natural outdoor spaces in apartment complexes and enhance their availability and usefulness. For this study, 21 environmentally-friendly factors were chosen and a checklist by specific item was prepared. This study examine how these items were applied to basic planning, detail design, and construction in 4 target areas. As a result, it was found that the development of environmentally-friendly residential areas was an ultimate goal of the project during basic planning and design. All target areas focused on developing an inner greens network, eco-pond, brook, and pedestrian track as well as the growth of a variety of plants. Some differences have been observed, however, in terms of method. Furthermore, due to economic and technological problems and poor construction site conditions, green walls/green roofs/pedestrian tracks/use of rainwater have not been properly promoted. These kinds of problems must be improved through the development of environmentally-friendly construction methods and materials, the expansion of natural grounds areas, economic support, a satisfactory repair and maintenance system.

  • Technology growth curve methodology is commonly used in technology forecasting. A technology growth curve represents the paths of product performance in relation to time or investment in R&D. It is a useful tool to compare the technological performances between Korea and advanced nations and to describe the inflection points, the limit of improvement of a technology and their technology innovation strategies, etc. However, the curve fitting to a set of survey data often leads to model mis-specification, biased parameter estimation and incorrect result since data through survey with experts frequently contain outlier in process of curve fitting due to the subjective response characteristics. This paper propose a method to eliminate of outlier from a technology growth curve using M-estimator. The experimental results prove the overall improvement in technology growth curves by several pilot tests using real-data in Defense Science and Technology Survey reports.

  • Animation has been developed as a part of artistry, and maintained a correlation with other various genres such as art, film and music to bring changes in form and to seek new things. Recently, technological advancement also has supported digitalization of producing process with variety in its method. Basic unit of animation production is a frame. A set of frames which has an image of producer's intention comes to life as animation when constructed, connected and transformed. A producer usually goes through a series of trouble when deciding how to express one's intention in images. Framing in animation is a kind of visual information which reflects producer's visual perception. A producer does not simply characterize matters into geometrical figures or give circumstantial explanation, but does framing work that relies on expression. Artistic psychology based on Gestalt Theory does not concentrate on abstract artistic philosophy with conventional beauty as its center, but pursues ambiguity and coherence of formative arts to support on accepting systematic order. Therefore, the purpose of this study is to find theoretical assistance which may be fundamental part in framing of animation. First, ten elements of Rudolf Arnheim centering on Gestalt Theory shall be redefined as concepts. Based on its ground, I will attempt to analyze shape-quality of framing of conventional animation, and make an approach with my personal experimental project. From this research project, I intend to analogize systematic aspect of framing in animation and to make framing of animation possible to assist in actual production of animation.

  • The current focus of domestic car industry is moving from technological development to reducing greenhouse gas. This study investigates and measures the HVAC system and indoor air condition of highway buses, which is conducted to develop a HVAC system using natural energy in the future. The measurements show that thermal balance is not fulfilled because heating sources are randomly placed, and relative humidity is in the 20 percent range both in HVAC and non-HVAC systems, which is far below 40%, or the highest thermal comfort level. CO2 concentration was found to be an average of 1500 ppm, but not more than 2522 ppm with 15 persons on board, and with 29 persons on board, an average of 2053 ppm, but not more than 3066 ppm, both of which far exceed allowed CO2 concentration level, or 1000 ppm. Generally, highway buses drop by rest stops and open doors for 15 to 20 minutes for getting in fresh air. But its air improvement effect is temporary, and it exacerbates indoor air condition.

  • The objective of this study is to increase bio-diversity by developing more efficient methods to created habitats and applying them in introducing prototypes of forest, grassland, and marsh which are found in natural ecosystem, to urban environment. In this context, in creating man-made marsh in Seoul Engineering High School, firstly, philosophical framework to create man-made marsh to restore urban nature and conceptual system to create a region considering life and ecosystem were established. Secondly, by applying the philosophical framework and the conceptual system, water quality section, plantation section, and techniques to create habitats to increase bio-diversity were introduced. Lastly, when the creation is completed, maintenance of the marsh will continue with participation and education of students and residents. This study presents how natural environment can be restored and created in urban areas. This may be viewed as modest beginning. I expect this study proves to be effective in increasing bio-diversity, fulfill its role as an experiment station for restoration and creation of natural environment and natural educational center for students and community as well as habitats for wild life, and open a new chapter in developing a society seeking co-existence of humankind and life. Therefore, when technological guideline on restoration and creation of man-made marsh in urban area is developed based on the outcome of this study, expansion of the project to nationwide including metropolitan cities like Seoul is recommended.

  • Over the last half-century, computer science has revolutionarily changed the landscape of humanities research. This digital shift in research methodology has reached from the brainstorming process to preserving, constructing, collecting, visualizing, and even analyzing materials. Such transformation has brought about the birth of the new field of study: Digital Humanities (DH). DH undeniably has saved much of the physical chores and provided a new angle to interpret the text, thereby making its meteoric rise as a promising future of the humanities. Based on such innovation, electronic circuitry can seem to replace the imagination that detects relationships and significances of research data with ever-improving interfaces. However, despite hitherto technological development, the thousands-year-old essence of traditional liberal arts-human creativity-remains the heart of humanities research and always will. This paper starts by proving this proposition in the way of comparing the old and new liberal arts research methods, focusing on literary studies. Meanwhile, it thoroughly investigates how digitalized bibliographies, search engines, databases, and digital projects provide the most useful data preservation and virtual experience of browsing in the library, along with their limitations due to the intrinsic quality of humanities research data. Also, it probes the differences between traditional and digital data analysis in current methods of literary studies, ultimately presenting the ideal direction for humanities development in the era of digital convergence.

  • The current GPS constellation consists of 32 Block IIA/IIR/IIR-M satellites including 12 Block IIA satellites on service over 15 years. The satellites in poor space conditions may suffer from anomalies, especially influenced by aging atomic clocks which are of importance positioning and timing. Recently, the IGS Ultra-rapid predicted products have not shown acceptably high quality prediction performance because the Block IIA cesium clocks may be easily affected by various factors such as temperature and environment. The anomalies of aging clocks involve lower performance of positioning in the GPS applications. We, thus, describe satellite clock behaviors and anomalies induced by aging clocks and their detection technologies to avoid such anomalies.
