  • Meorological data have been collected to monitor the wetland area in Goheung bay since 2003 and four intensive observations were conducted to study effects of the atmospheric turbulence on the energy budget and the ecological changes. We improved an algorithm to estimate the sensible heat flux with routine data. The sensible heat flux estimated by gradient method was in good agreement with that measured by precision instruments such as surface layer scintillometer and ultrasonic anemometer. Diurnal variations of sensible heat flux showed analogous tendency to those of temperature gradient. When the vertical wind shear of horizontal wind components was weak, even though temperature gradient was strong, the gradient method underestimated the sensible heat flux. A compensation for the cloud will make this gradient method be a helpful tool to monitor the ecosystem without expensive instruments except for weak wind shear and temperature gradient.

  • The purpose of this study is to analyze the methods applied to educational facilities of Steven Holl's architecture, especially focusing on sensible elements in the public space. Steven Holl has realized distinct space by applying very specific and limited concept. such as perspective space, color, light and shadow, time duration and perception, haptic realm, and proportion & scale. Education facilities designed by Steven Holl, are influenced the sensible aspects of space, form, materials, patterns, and other various sensible elements. Beyond the limits of color and sculptural vocabulary, Steven Holl utilizes a variety of ways which shown in educational facilities design and is identified by the emotional phenomenology of perceptual experience. Various elements in the public space are reinforced through light and materials to make experiential space in the educational facilities. This study used a composition of space that combines various sensible elements, meanings, and senses to examine how Steven Holl's architecture can mediate and reproduce user' emotional experiences and discover the existential relationship between space and user in public space of educational facilities.

  • The essay discusses the way in which the aesthetic of Pre-Raphaelites reformulates the habitual system of knowledge in the Victorian age by adapting $Ranci{\acute{e}}re^{\prime}s$ concept of aesthetics. $Ranci{\acute{e}}re$ develops an original theory of aesthetics, a regime of knowledge which enables to perceive and reflect art as such. In this way, aesthetics turns to be the logical system by which the consensus idea of the beautiful comes to exist. For $Ranci{\acute{e}}re$, aesthetics is an agreed system of the sensible and reproduces the habitual knowledge of the world. Therefore, a new aesthetic movement means an attempt to break the given aesthetics and reorients the new distribution of the sensible. The important point of $Ranci{\acute{e}}re^{\prime}s$ argument is that he does not presuppose the dimension beyond the present unlike Frankfurt School. What $Ranci{\acute{e}}re$ claims is that there is no such the aesthetic which can correct the instrumental reason, but rather an indifferent moment in which a worker finds out himself as a creator who can give rise to the new regime of the sensible and feels free from what he must work for. From this perspective, the essay explores the aesthetic of Pre-Raphaelites and its meaning in nineteenth century Britain. Pre-Raphaelites was an artist group who railed against a so-called academic style of paintings and created a new aesthetic criterion to describe the truth of the natural world. The essay examines the interrelationship between Pre-Raphaelites and photography that would enable them to re-distribute the sensible and produce a new way of seeing the order of things. This is related to the birth of a modern gaze as in the case of landscape paintings. What is crucial is that the distribution of the sensible is always-already doubled with the political. In short, Pre-Raphaeltes is not only an aesthetic movement but also a political pursuit to achieve a disenchanted perception of nineteenth century industrial capitalism.

  • In this paper, a sensory effect authoring tool is introduced to effectively generate sensory effect metadata for sensible media. Sensible media manifests sensory effects in the media to real world by stimulating sensory organs of human. It is emerging as a new media to enhance the user's immersion towards media. For the successful deployment of the sensible media industry, an effective authoring tool is required to provide easy authoring of sensory effect metadata. The result of the authoring tool design and development based on MPEG-V(ISO/IEC 23005-3) International Standard is presented in this paper.

  • An experiment was carried out to investigate the effect of a coolant circuit arrangement on the heat transfer and air pressure drop of a fin-tube sensible heat exchanger with the corrugated fin surface. The air inlet temperature was set to $23^{\circ}C$,the relative humidity to 50% and the air inlet flow rate to 20, 22, $25m^3/min$, respectively. while the coolant temperature was set to $7^{\circ}C$, and the coolant mass flow rate to 10, 16, 22kg/min, respectively. Experiment showed that the exchanger having a diameter of 12.7mm with parallel circuit does better performance in sensible heat transfer and air pressure drop than those three of diameter of 12.7mm with a series circuit and that with diameter of 15.88mm with a parallel circuit.

  • Micrometeorlogical and upper air observation have been conducted in order to determine the atmospheric boundary layer depth based on data from satellite and automatic weather systems. Terra/MODIS temperature profiles and sensible heat fluxes from the gradient method were used to estimate the mixed layer height over a coastal region. Results of the integral model were in good agreement with the mixed layer height observed using GPS radiosonde at Wolsung ($35.72^{\circ}N$, $129.48^{\circ}E$). Since the variation of the mixed layer height depends on the surface sensible heat flux, the integral model estimated properly the mixed layer height in the daytime. The buoyant heat flux, which is more important than the sensible heat flux in the coastal region, must be taken into consideration to improve the integral model. The vertical structure of atmospheric boundary layer can be analyzed only with the routine data and the satellite data.

  • Bypass air conditioning systems are divided into three types; an outdoor air bypass, a mixed air bypass and a return air bypass system. What makes the return air by pass system more effective is that it directs all of moist outdoor air through the cooling coil. The bypass air conditioning system can maintain indoor R.H (Relative Humidity) less than a conventional CAV (Constant Air Volume) air conditioning system by adjusting face and bypass dampers at part load. When a design sensible load (the ratio of sensible load to total sensible load) is 70 percent (at this time, RSHF (Room Sensible Heat Factor) . 0.7), indoor R.H was maintained 59 percent by the return air bypass system, but 65 percent by the conventional CAV air conditioning system (valve control system). The bypass air conditioning system can also improve IAQ (Indoor Air Quality) in many buildings where the number of air change is high.

  • A sensible media simulation system for automobiles is introduced to open up new possibilities for an in-car entertainment system. In this paper, the system architecture is presented, which includes a virtuality-to-reality adaptation scheme. Standard data schemes for context and control information from the International Standard MPEG-V (ISO/IEC 23005) are introduced to explain the details of data formats, which are interchangeable in the system. A sensible media simulator and the implementation of a sensory device are presented to prove the effectiveness of the proposed system. Finally, a correlation between learning styles and sensory effects (that is, wind and vibration effects) is statistically analyzed using the proposed system. The experiment results show that the level of satisfaction with the sensory effects is unaffected overall by the learning styles of the test subjects. Stimulations by vibration effects, however, generate more satisfaction in people with a high tactile perception level or a low visual perception level.

  • This study explores the types of lifestyle of females living in urban areas, and examines the relationship between the types of lifestyle and the preference for interior design images. The research sample is 301 adult females in Kwangju City, Korea. The sample is divided into two groups by employment status. Based on eight lifestyles by related factors, four major lifestyle types are classified: traditional type, private and sensible type, passive and private type, and environment-oriented and sensible type. The portions of these types are 32.6% of passive and private type, 21.6% of environment-oriented and sensible one, 21.6% of active and sensible one, and 16.6% of traditional one. The research of the lifestyle types reveals that they differ by age, marital status, education, and dwelling types. There are negligible differences among four types in preference for three interior design images.
