Recently, as human-centered design and humanization of space accelerates, the concept of physical space is changing to user-centered space. In particular, in the case of exhibition space to utilize digital media, visitors' actively experiencing exhibits and participating exhibition are regarded as an important factor, thus affordance design serves as a crucial factor to afford satisfaction with exhibition space to the visitors. Accordingly, the study is to understand the concept of the affordance and the digital media exhibition environment and to analyze the preference for each affordance design factor in the digital exhibition environment. The survey is conducted to people in the twenties who inhabit Seoul and the metropolitan area, familiar with the digital media. The results of the survey show that the most important role of the digital media in the exhibition environment is to create the atmosphere for concentration and complexity is the most preferable among interactivity, network ability and complexity, the feature of the digital media. Additionally, the results reveal that cognitive affordance presenting the feature of design to help the user when he/she want to know something is the most preferable among sensory affordance, physical affordance, cognitive affordance and functional affordance and as the time exposed to the digital media increases the importance of the affordance design is high. As the digital environment is common now in many fields, it will be regarded as a crucial factor to the visitors of an exhibit hall from now on whether affordance design is used.

대용량 멀티미디어 파일의 증가와 개인의 디지털 정보의 중요성이 날로 증가하면서 저장장치는 고용량화, 고집적화 되는 방향으로 발전하고 있다. 따라서 저장장치에 발생되는 물리적인 오류는 단순히 작은 영역의 손상이 아닌 매우 넓은 영역에 대한 정보 손실로 이어진다. 이를 방지하기 위해서는 시스템을 사용하기 전에 물리적인 오류에 대한 시스템의 강인성과 대처 수준을 검증하고 사용해야 한다. SOAR(Storage Reliability Analyzer)는 검증의 핵심이 될 수 있는 물리적인 오류 발생 기능과 복구 기능을 가지고 있으며 이것은 시스템에 대한 신뢰성과 강인성을 검증 할 수 있는 유용한 도구이다. 이 기능을 보다 편리하게 사용하기 위해서 SOAR는 3가지의 특수한 오류 적용 기법과 파일시스템에 특화된 2가지 기법을 가지고 있다. 본 논문에서는 SOAR를 이용해서 어플리케이션부터 파일시스템까지 물리적인 오류에 대한 검증을 실제 수행하고 결과 분석을 진행하였다. 그러므로 SOAR는 물리적인 오류에 대한 시스템의 많은 문제점을 발견하였고 동시에 그 기능을 증명하였다.

The drug therapy for rheumatoid arthritis must be maintained constantly or for the whole life but is apt to induce the adverse effects in gastrointestinal or renal system. Therefor, newer methods are paid attention to reduce adverse effects. The thirty-two rat female separated into seven groups depending on the therapy or Freund's adjuvant applied: Normal group(n=8) not received anything, Positive control group(n=8) only received adjuvant, USC group(n=8) received continuous US, USP group(n=8) received pulsed US. The physical and radiological findings by thermal and non-thermal effects of ultrasound were evaluated in groups with continuous mode at 1 MHz, $0.5\;W/cm^2$ for 6 minutes and with pulsed mode (duty cycle 1:9) at 1 MHz, $0.5\;W/cm^2$ for 6 minutes. The result summarized followings. 1. Swelling of forepaw and hindpaw was significantly reduced in USP. 2. Arthritis indices in USP group were significantly reduced than those in PCG. 3. In naked eye and radiologic findings, swelling was significantly prevented in USP group but not in PCG. The change of swelling, arthritis index, gross feature in naked eye, radiologic finding were significantly improved in all groups except for USC group, taking care for using its continuous mode.

This study is to investigate the conditions closely related to the establishment of vegetation in the riparian zone: the soil condition, an important factor along with climate and light. Especially, the soil structure of the microtopographical formations in the specific area known as the riparian microtopographical zone investigated. In addition, the effect of the riparian microtopographical features on the ground water level, soil moisture content, and vegetation was studied. The results of this study are as follows; 1) At all sample sites, below the sand layer, a gravel layer is always present. This is the result of past floods. 2) Although Salix koreensis experiences frequent disturbances such as increase in river level and floods, this vegetation establishes itself in the most secure are in the microtopographical zone. 3) The growth of Phragmites japonica is closely related to the underground water level. 4) It is clear that Miscanthus sacchariflorus grows concentrated in dry areas. 5) The soil accumulation conditions differ according to the soil moisture content of each microtopgraphical feature. Accordingly, the moisture content of the soil is clearly different within the microtopographical zone. The continuous and long-term investigation and research on the relation of riparian reproduction and the relevance with location surrounding factors are necessary in the future.

스팬 30m 이상을 갖는 건축물로 한정하여, 1960년대 이후 건립된 국내 공공 대공간 건축물의 발달과정과 건립특성에 대하여 연구하였다. 국내 대공간 건축의 용도와 규모의 현황을 살펴보고 구조방식이 건립된 건축물에 미치는 영향을 살펴보고자 한 것이다. 연구결과, 1980년대-90년대에는 스팬 40-70m 규모의 체육시설이 집중적으로 건립되었으나 2000년 이후에는 용도가 다양화되면서 대규모의 컨벤션센터 건립이 다수 이루어지고 있는 것으로 나타났다. 또한 초기 독특한 구조형태와는 달리 80년대에는 입체트러스가 보편적으로 활용되었고, 2000년 이후에는 형태효과를 고려하여 구조체를 고안하거나 새로운 구조시스템을 활용하는 시도가 보여지고 있다.

Sanduleak's star is a suspected symbiotic binary located in the Large Magellanic Cloud. It is known that it has a giant jet with physical size ~ 14pc. Its spectrum shows two strong emission bands at $6825{\AA}$ and $7082{\AA}$, which are originated from Raman-scattering of O VI by neutral hydrogen atoms. We present the high-resolution spectrum of Sanudleak's star obtained with MIKE at the Magellan-Caly telescope to investigate the O VI emission region based on the profiles of the two Raman features. In this spectrum, it is noted that the Raman $6825{\AA}$ feature exhibits a single broad peak profile, which is in high contrast with a clear triple peak profile of the Raman $7082{\AA}$ feature. In our analysis we suggest that the O VI emission region consist of three main emission parts: an accretion disk, a bipolar outflow and an optically thick, compact component surrounding the white dwarf. By performing Monte Carlo simulation we constrain the representative column density of the H I scattering region N_HI ~1${\times}$10^23 cm^-2, which is in accordance with the observed flux ratio in the two Raman features F(6825)/F(7082) ~ 4.5.

This paper describes a method for achieving a novel design within a class of 3D objects that would create a preferred impression on users. Physical parameters of the 3D objects that might strongly contribute to their visual impressions are sought through computational investigation of the impression ratings obtained for learning samples. "Car body" was selected as the class of 3D objects to be investigated. A morphable 3D model of car bodies that describes the variations in appearance using a smaller number of parameters was obtained. Based on each car body's rating for the impression of speediness obtained by paired comparison, the visual impression was transformed by manipulating the parameters defined in the morphable 3D model. The validity of the proposed method was confirmed by psychological experiments. A new scheme is also proposed to properly re-sample a novel object of a peculiar shape so that such an object could also be represented by the morphable 3D model.

We propose an individual identification method using a single-lead electrocardiogram signal. In this paper, lead I ECG is measured from subjects in various physical and psychological states. We performed a noise reduction for lead I signal as a preprocessing stage and this signal is used to acquire the representative beat waveform for individuals by utilizing the ensemble average. From the P-QRS-T waves, features are extracted to identify individuals, 19 using the duration and amplitude information, and 16 from the QRS complex acquired by applying Pan-Tompkins algorithm to the ensemble averaged waveform. To analyze the effect of each feature and to improve efficiency while maintaining the performance, Relief-F algorithm is used to select features from the 35 features extracted. Some or all of these 35 features were used in the support vector machine (SVM) learning and tests. The classification accuracy using the entire feature set was 98.34%. Experimental results show that it is possible to identify a person by features extracted from limb lead I signal only.

The purpose of this study was to examine the awareness of racial features, racial in-group classification and preference by Korean children. The study participants comprised 89 children aged 3-5 years. The children performed photograph description and choice tasks. The major findings were as follows: First, older children were significantly more likely than younger children to use racial feature and less likely to use general physical feature to describe the stimuli. Second, children tended to select the South-Asian person speaking in Korean language as a Korean, rather than the Korean person speaking in English. Third, children tended to select the person of Korean appearance speaking in English as a playmate. The result revealed the developmental features of racial awareness. Furthermore the correspondence of language plays an important role on the children's in-group classification whereas the correspondence of appearance plays an important role on the children's preference.
