  • An intelligent robot, which has been developed recently, is no more a conventional robot widely known as an industrial robot. It is a computer system embedded in a machine and utilizes the machine as a medium not only for the communication between the human and the computer but also for the physical interaction among the human, the computer and their environment. Recent advances in computer technology have made it possible to create several of new types of human-computer interaction which are realized by utilizing intelligent machines. There is a continuing need for better understanding of how to design human/robot interface(HRI) to make for a more natural and efficient flow of information and feedback between robot systems and their users in both directions. In this paper, we explain the concept and the scope of HRI and review the current research trends of domestic and foreign HRL. The recommended research directions in the near future are also discussed based upon a comparative study of domestic and foreign HRI technology.

  • Orange carotenoid protein (OCP) of photosynthetic cyanobacteria binds to ketocarotenoids noncovalently and absorbs excess light to protect the host organism from light-induced oxidative damage. Herein, we found that mutating valine 40 in the α3 helix of Gloeocapsa sp. PCC 7513 (GlOCP1) resulted in blue- or red-shifts of 6-20 nm in the absorption maxima of the lit forms. We analyzed the origins of absorption maxima shifts by integrating X-ray crystallography, homology modeling, molecular dynamics simulations, and hybrid quantum mechanics/molecular mechanics calculations. Our analysis suggested that the single residue mutations alter the polar environment surrounding the bound canthaxanthin, thereby modulating the degree of charge transfer in the photoexcited state of the chromophore. Our integrated investigations reveal the mechanism of color adaptation specific to OCPs and suggest a design principle for color-specific photoswitches.

  • Local resources can be employed as an original resource for local revitalization. This study has investigated the local resource, and then categorized these to suggest the implication available to the industrialization. Local resources were classified into 5 categories(with 25 subcategories), including remains and ruins, ethnic custom, manners and customs, people, traditional food and the principal product, and the natural ecology environment. Three phases were carried out in this study. We made lists of local resources and analyzed applicable resources among the lists. Also, we selected the target resources for the survey in Gimpo, and also analyzed the application for industrialization. Of all these resources, 560 cases were first investigated, then 51 local resources were in-depth analyzed. Based on this result, the application plan was investigated, dividing the central resources and the connection resources.

  • During high speed economic growth period in Korea, our society has focused it's energy on the economic and social development based on the strategy of demolition and destruction of all our natural and man-made environment. In progress with that trend, our small cities in Korea also have just followed the metropolitan physical development pattern and considered that imitation of those metropolitan cities' or western cities' changes be the same meaning of "modernization". Therefore, our valuable urban and architectural heritages have been constantly destructed and that situation has been same in Anseong. Now in the new trend of environmentally sustainable urban design and at the new millenium period, we have to focus our attention on the retaining strategy of city's historicity as a city planner or an architect, and the first step for this strategy shall be to clarify the transition process of urban structure, especially of C.B.D. area of small cities since pre-industrial period.

  • The theory of Place is based on the relations of human being, environment and architecture in the view of the existentialism and phenomenology. A place has two respects, the one is Natural place as landscape and the other is Man-made place as city, public building , private house. These properties of place are appeared through axis , directions, boundaries, centers , enclosures that are basic elements in architecture . Therefore these elements embody sense of place as orientation , identification , identity. imageability, stabilitas loci, heirarchy. And these sensually compositional elements of poace concretize district, landmark, node, path, edge that ceate a setting into work and place in architecture & interior design.

  • The purpose of this study was to ascertain the prey composition and utilization of the Eurasian otter, Lutra lutra, in the ecosystem conservation region of the Seomjin River. The study was conducted for a 12-month period from March 2003 to February 2004 by spraints analysis and an investigation using artificial holts. We found seasonal variation in the number of spraints and composition of prey items. Fish were the main prey items throughout the period (82%), and other prey items included birds (14%), amphibians (2%) and arthropods (1%). In addition to prey identification, we investigated habitat utilization by otters through spraints distribution. The traces of otters were discovered in five of the six total artificial holts. However, the utilization of the artificial holts in the study area seemed to be limited as evidenced by the low frequency of traces in the holts.

  • Environment-friendly design becomes one of the main issues of the contemporary design. It has been developed with the advent of the organic view of the wend. It started as the environment-protective orientation and then enlarged its boundary including the designs which aims to revive the organic relationship between human and nature. Recent design approach in environment design emphasizes to be 'synchronized with the nature' and its basic attitude is the revival of the right relationship between man and nature. It also can be described as the design for Green Amenity. This paper researches on the concepts, types and the roles of the environmentally-friendly design. There are two basic concepts : one is environment-protective attitude and the other is the attitude which emphasizes the function of Green Amenity. This paper focuses on the latter approach. Through the analysis of the necessity and the function of the environmentally-friendly design, it aims to prove the fact that valuable human life need the design which connects human life aye with natural environment.

  • Bacterial cellulose (BC) is generated from citrus gel by Gluconacetobacter hansenii TL-2C. BC has good properties such as high-burst pressure, high-water contact and the ultrafine highly nanofibrous structure of mimic natural extracellular matrix (ECM) for tissue engineering. In this study, acrylic acid (AAc) was grafted onto BC surfaces under aqueous conditions using gamma-ray irradiation, and then immobilized gelatin onto AAc-g-BC. The characterization of scaffolds was performed by scanning electron microscopy (SEM), attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), toluidine blue O (TBO) assay. Morphology of gelatin and AAc incorporation onto BC nanofibers did not changed. Our study suggests that gelatin-immobilized BC nanofibers scaffold has a potentiality to fabricate 3D nanofibrous scaffolds for tissue engineering.

  • In this study, an experimental approach to measure a suite of low weight hydrocarbons was investigated with an emphasis on ethylene (EL) along with many others (ethane (EA), propane (PA), propylene (PL), n-butane (BA), acetylene (AL), methyl acetylene (ML)). Their concentrations were quantified using GC-FID system equipped with thermal desorption (TD) system. The TD-based analysis was conducted using both Link Tube/Thermal Desorber (LT/TD) method and Modified Injection through a Thermal Desorption (MITD) method. The results of these analyses were evaluated in a number of respects. The system allowed the detection of all compounds except methane with the mean response factor (RF) of 10.28 (EA) to 11.94 (PL). The method detection limits of target compounds were seen in the range of 0.027 (ML) to 0.146 ng (BA). The emission flux of some environmental samples (fruits), when measured using a small flux chamber system, fell in the range of 0.14 (AL: Kiwi) to $181ng{\cdot}g^{-1}{\cdot}hr^{-1}$ (EL: Apple Peel). The results of this study confirm that the experimental approach developed in this study allows to accurately measure emissions of low weight hydrocarbons (LWHC) like ethylene from various natural and man-made source processes.
