본 연구에서는 메탄의 coupling 반응에서 Ca-Ni-K 산화물 촉매의 원소비 변화에 따른 촉매의 활성도 및 C₂에 대한 선택도를 고찰하였다. 또한 최적반응조건에서 물이 본 반응에 미치는 영향과 촉매표면의 산소에 의한 산화상태의 변화효과도 함께 검토하였다. 실험결과 Ca₄NiK_(0.1)OX 촉매가 탄화수소 선택도에 있어서 가장 우수한 것으로 확인되었으며 Ca₃NiK_(0.1)OX 촉매가 반응활성도에 있어서 가장 우수하였다. 반응물에 H₂O를 첨가하면 탄화수소의 선택도와 반응전화율을 함께 증가시킬 수 있었으며 촉매표면의 산화상태가 촉매의 활성도 및 선택도에 중요한 인자인 것으로 나타났다. In this study, catalytic activity and selectivity to C₂ hydrocarbons on oxidative coupling of methane over Ca-Ni-K oxide catalysts were studied by varying the atomic ratio of the catalyst. In addition, effects of water as an additive reactants and the effect oxidative pretreatment of surface on the catalysts performance were investigated. It was established that, for the methane coupling reaction Ca₃NiK_(0.1)OX proved to be a better catalyst in catalytic activity, Ca₄NiK_(0.1)OX was best among the catalysts tested. As far as hydrocarbon selectivity is concerned water as an additive reactant enhanced hydrocarbon selectivity and the reaction conversion simultaneously, and it was found that oxidation state of catalyst surface is an important factor for catalytic activity and selectivity of this reaction.

The effects of task characteristics on the relative efficiency of visual display dimension were studied using a simulated tele-robotic task. Through a conventional method of task analysis. the tele-robotic task was divided into two categories: the task element requiring focused attention (FA task) and the task element requiring global attention (CA task). Time-ta-completion data were collected for a total of 120 trials involving 10 participants. For the CA task. there was no significant difference between the multiple two-dimensional (20) display and the three-dimensional (3D) monocular display. For the FA task. however. the multiple 20 display was superior to the 3D monocular display. The results suggest that the characteristics of a given task have a considerable effect on the choice of display dimensionality and the multiple 3D display is better for human operators to effectively judge depth if the task requires frequent use of focused attention.

Loss of postural balance can possibly lead to increased risk of slips and falls in work places. Present study was performed to investigate the effects of noisy environments on postural stability during standing. It is known that a sound is characterized by the frequency and pressure level of the sound. Therefore, effects of the frequency and pressure level on postural stability were of primary concern. Ten male subjects participated in the experiment. Subject's center of pressure(COP) position was collected on a force plate while they were exposed to different frequency and pressure levels of the sound. Measured COP was then converted into the length of postural sway path in both anterior-posterior(AP) and medio-lateral(ML) axis. Results showed that the length of sway path in AP axis was significantly affected by the frequency of sound. The length of sway path was lowest at frequency level of 2000Hz and increased below and above this frequency range. The sound pressure level, however, did not significantly affect the postural sway length in both AP and ML axis. The results imply that industrial workers in noisy environments should be aware that their abilities of postural balance can be disturbed significantly.

The study was done in order to better understand the stress which physical therapist experience during clinical training. Clinical training was not confined to understanding training facts and concepts of physical therapist. The data were collected from November 1 to December 15, 2002 and 129 valid questionnaires were obtained and analyzed. They were analyzed by the percent, frequency, t-test, one-way ANOVA and Pearson Correlation Coefficient. The results of the study were as follows: 1. There were in satisfaction degree of major 42.6% of the subjects was revealed as "satisfied" and in satisfaction degree of clinical training 24.0% of the subjects was revealed as "satisfied". 2. There were much stress in relation of physical therapist was revealed as the most severe stress at a mean 15.98 and environment was revealed as severe stress at a mean 12.94. in role was revealed as the lessor stress at a mean 4.12. 3. The state anxiety degree which physical therapist students experience during clinical training was revealed as "moderate" anxiety. 4. There were significant difference between relation of physical therapist and satisfaction degree of clinical training (p<0.05), between ideal and values of physical therapist and health condition(p<0.05), between relation of tint and satisfaction degree of major(p<0.05), between education the characteristic which it will pull out and satisfaction degree of major(p<0.05), satisfaction degree of clinical training(p<0.05).

Geant4를 이용한 STEIN 검출기의 입자 분리 검출 모의실험 예비 결과 분석

박성하,김용호,우주,선종호,진호,이동훈,Park, Seong-Ha,Kim, Yong-Ho,U, Ju,Seon, Jong-Ho,Jin, Ho,Lee, Dong-Hun 한국천문학회 2012 天文學會報 Vol.37 No.2

지구 자기권에 존재하는 플라즈마 입자의 다중관측을 목적으로 개발된 초소형 탑재체 STEIN (SupraThermal Electron, Ion, Neutral) 은 경희대학교와 UC Berkeley가 공동으로 개발 중인 3대의 초소형 과학위성 TRIO-CINEMA (TRiplet Ionosphere Observatory - Cubesat for Ion, Neutral, Electron and MAgnetic fields) 에 탑재될 입자 검출기이다. 32개의 픽셀로 이루어진 STEIN 검출기는 2~300 keV의 전자, 4~300 keV의 이온과 중성입자(Energetic Neutral Atom: ENA) 를 분리 계측할 목적으로 설계되었으며, 하전입자가 정전장 편향기를 통과하여 서로 다른 검출기 픽셀에 도달함으로써 전자와 이온, 중성입자를 분리하여 계측할 수 있도록 하였다. 한편, STEIN 구조물에서 발생한 2차 입자의 검출을 방지하기 위해 정전 편향기 사이에 차단날(blade)을 설계하였다. 본 연구에서는 STEIN 모의실험 예비 결과로써 전기장에 크기 및 차단날에 의한 하전입자의 궤적과 이에 따른 분리 계측 성능을 알아보고자 Geant4 (GEometry ANd Tracking)를 사용하여 검출기 픽셀에 입사하는 전자의 초기 위치를 분석하였다. 전자의 입사 위치는 검출기로부터 5 cm 전방에서 6 mm * 20 mm 범위 내에서 무작위로 생성하여 검출기의 방향으로 수직 입사하였다. 분석 결과 전자들은 전기장의 방향에 따라 편향되는 결과를 보였으며, 저에너지 전자는 강한 전기장의 영향으로 차단날에 의해 차폐되어 검출되지 않았다. 따라서 전기장의 크기와 차단날에 따른 입자 분리 검출이 가능함을 본 모의실험을 통해 확인하였으며, STEIN 운용 시 입자 분리 검출 및 결과 분석 기반으로 본 연구 결과를 사용될 수 있을 것으로 기대된다.
