Purpose: A study of university students was conducted to explore their prejudice toward AIDS, social interaction with AIDS patients, and intention to practice AIDS preventive measures. Method: This study used a cross-sectional descriptive survey design. A self-reported questionnaire was completed by 145 university students. Data were analyzed using descriptive statistics, t-test, and ANOVA with SPSS 11.5. Result: The mean score for prejudice toward AIDS was 23.54, implying a low level of prejudice toward AIDS by the subjects. The mean score for social interaction with AIDS patients was 20.92, indicating a moderate level of intention for social interaction with AIDS patients. The mean score for intention to practice AIDS prevention was 24,74, assuming a strong intention to practice AIDS prevention. Those who had higher mean scores for AIDS Knowledge showed significantly higher mean scores for social interaction with AIDS patients and intention to practice prevention than those who had lower scores. Conclusion: Research findings showed that university students had a low level of prejudice toward AIDS, a moderate level of social interaction with AIDS patients and a high level of intention to practice AIDS prevention. Therefore, a specially designed AIDS education program is needed for university students so as not to provoke fear or stigma toward AIDS patients and to support AIDS patients.

Interaction requires dynamic relationship between objects. In ubiquitous computing environment, interaction between human and the environment is implied. Tactile interaction has so far been less addressed, while tactile sensation should be an important topic in the field of multimedia study. This paper describes development of a novel PVDF (Polyvinylidene Fluoride) dynamic tactile sensor and associated experiments. PVDF dynamic tactile sensors detect touch events applied to the sensor skin by low frequency components of the signal. Rubber skin-covered sensing material was mounted on the bones. Robust performance with low noise was figured out in our robotic experiment. Whereas most conventional sensors are interested in measurement, our dynamic tactile sensor is sensitive to change of state, which could be a key for economic understanding of happenings in the dynamic world. We note that dynamic sensing uses motion as a part of sensing modality We suggest that dynamic sensing be understood in technological terms in the perspective of interactive media and ubiquitous computing.

The purpose of this study is to compare the difference in the interactions between beginning language learners and heritage learners on their forms based on the interaction hypothesis. In this study, three types of information gap activities were used to analyze Language Related Episodes (LREs) while investigating the interaction patterns in language use between four pairs (eight learners) of foreign learners and four pairs (eight learners) of English-speaking heritage learners. The result indicated that foreign learners had a high focus on form during interaction. In particular, they had a tendency to focus on vocabulary rather than grammar, and they conducted self-repair by examining and mostly adjusting their speech to postposition and tense. However, in the problem-solving process, they showed a limited ability in interaction, and thus directly asked others to settle the problem or resorted to using English due to their lack of ability to employ various communication strategies. However, heritage learners had a relatively low focus on form compared to foreign learners. Yet, they also focused more on vocabulary rather than grammar and conducted self-repair in interaction, especially for vocabulary. In addition, they were skillful at using various communication strategies such as indirect expressions, use of alternative words, evasion, and delaying, to expand speech and prevent communication breakdown. They focused less on grammar and mostly did not provide negative feedback in interaction.

In this study, a position and force simultaneous trajectory tracking control algorithm is proposed for a driving apparatus that consists of two pneumatic cylinders connected in series. The controller applied to the driving apparatus is composed of a non-interaction controller to compensate for interaction between cylinders and a disturbance observer aimed to reduce the effect of model discrepancy that cannot be compensated by the non-interaction controller. The effectiveness of the proposed control algorithm is proved by experimental results.

Use of low bandgap polymers is the most suitable way to harvest a broader spectrum of solar radiations for solar cells. But, still there is lack of most efficient low bandgap polymer. In order to solve this problem, we have synthesised a new low bandgap polymer and investigated its interaction with the ILs to enhance its conductivity. ILs may undergo almost unlimited structural variations; these structural variations have attracted extensive attention in polymer studies. In addition to this, UV-Vis spectroscopy, confocal Raman spectroscopy and FT-IR spectroscopy results have revealed that all studied ILs (tributylmethylammonium methyl sulfate [$N_{1444}$][$MeSO_4$] from ammonium family) and 1-methylimidazolium chloride ([MIM]Cl, and 1-butyl-3-methylimidazolium chloride [Bmim]Cl from imidazolium family) has potential to interact with polymer. Further, protic ILs shows enhanced conductivity than aprotic ILs with low bandgap polymer. This study provides the combined effect of low bandgap polymer and ILs that may generate many theoretical and experimental opportunities.

Effects of dietary cellulose and protein levels on nutrient utilization in chickens were investigated. Four experimental diets containing 5% (low cellulose) or 20% (high cellulose) cellulose in combination with 10% (low protein) or 20% (high protein) protein of 70 g/day were alternatively forced-fed to eight colostomized White Leghorn cockerels once a day to make $4{\times}4$ Latin-square design. The digestibilities of DM and energy decreased with the increase in cellulose level, but not affected by dietary protein level. Ether extract digestibility was higher in the high cellulose diets than in the low cellulose protein level. Ether extract digestibility was higher in the high cellulose diets than in the low cellulose diets. The digestibility of nitrogen free extract had the same trend with the digestibility of DM and energy. The digestibility of acid detergent fiber was not so much different among the diets, but the NDF digestibility was lower in the high cellulose diets than in the low cellulose diets, due to the low hemicellulose digestibility. The true digestibility of protein was influenced by both of the dietary protein and cellulose levels, and their interaction was found. The dietary protein level affected the biological value of protein but the dietary cellulose level did not, and consequently the biological value of protein in the low protein diets was lower than in the high protein diets.

The fluid induced vibration (FIV) phenomena of a 2-D.O.F airfoil system have been investigated in low Reynolds number incompressible flow region. Unsteady flows with viscosity are computed using two-dimensional incompressible Navier-stokes code. To validate developed Navier-Stokes code, steady and unsteady flow fields around airfoil are analyzed. The present fluid/structure interaction analysis is based on the most accurate computational approach with computational fluid dynamics (CSD) and computational structural dynamics (CSD) techniques. The highly nonlinear fluid/structure interaction phenomena due to severe flow separations have been analyzed fur the low Reynolds region (R$_{N}$ =500~5000) that has a dominancy of flow viscosity. The effect of R$_{N}$ on the fluid/structure coupled vibration instability of 2-DOF airfoil system is presented and the effect of initial angle of attack on the dynamic instability are also shown.own.

이 연구에서는 초등 예비교사를 대상으로 반성적 사고가 과학 수업에서 교사의 언어적 상호작용에 미치는 효과를 알아보았다. 연구를 위해 2명이 예비교사가 선정되었고, 각 예비교사마다 3차시의 과학 수업을 하였으며, 연구자가 매 차시 과학 수업을 녹화 녹음하였다. 녹음된 자료 중 1차시와 3차시의 자료만 교사의 언어적 상호작용을 분석하기 위해 전사하였다. 예비교사의 언어적 상호작용의 변화와 특징을 분석한 결과, 수업이 진행될수록 교사의 언어적 상호작용 빈도가 증가하는 것으로 나타났다. 그러나 상호작용 빈도의 증가는 예비교사의 과학 수업에 대한 관점과 수업 준비도에 따라 다른 패턴을 보였다. 또한 예비교사의 언어적 상호작용의 질적 변화를 분석한 결과, 수업이 진행될수록 학생들의 사고를 자극하거나 열린 사고를 유발하는 높은 수준의 상호작용이 증가하고, 학생들에게 닫힌 사고를 유발하는 낮은 수준의 상호작용은 다소 감소하는 경향을 나타냈다. 이러한 변화 역시 예비교사의 개인적 특성에 따라 다르게 나타남을 알 수 있었다. 따라서 과학 수업에서 반성적 사고를 통한 교사의 언어적 상호작용의 변화에 효과는 있었으나, 예비교사 개인의 특성 특히, 과학 수업에 대한 관점과 준비도에 따라 효과의 정도가 다름을 알 수 있었다.
