Hydrosilanes possessing reactive Si-H bond are used in synthesizing various types of polysilanes by dehydrocoupling under the influence of various organometallic promoters. Catalytic Si-Si/Si-O coupling of hydrosilanes with hydrosilanes, alcohols, and lactones to silicon-based polymers are described in this article as selective examples of our recent research developments. These silicon-containing polymers can be used as a precursor to prepare useful functional materials for fabricating electronic devices.

김명희,주수종,Kim, Myung-Hee,Joo, Su-Chong 한국정보처리학회 1997 정보처리논문지 Vol.4 No.11

This paper presents an analysis on the optimal partitioning configuration of cache (memory) for meeting deadlines of periodic and aperiodic real-time task set. Our goal is not only to decrease the deadline missing ratio of each task by minimizing the task utilization, but also to allocate another tasks to idle spaces of cache. For this reason, we suggest an algorithm so that tasks could be allocated to cache segments. Here, the set of cache segments allocated tasks is called a cache partitioning configuration. Based on how tasks allocate to cache segments, we can get various cache partitioning configurations. From these configurations, we obtain the boundary of task utilization that tasks are possible to schedule, and analyze the cache optimal partitioning configuration that can be executed to minimize the task utilization. 본 논문은 실시간 시스템에서 주기 및 비주기적 태스크들의 마감시간 만족을 위한 캐쉬(캐쉬 메모리)의 최적 분할 형태를 분석한다. 연구 목적은 태스크들의 가용비용을 최소화하여 태스크들의 마감시간 위반율을 줄일 뿐 아니라 캐쉬의 유휴공간을 다른 태스크에게 할당시키기 위함이다. 이를 위해 캐쉬의 분할공간에 태스크들을 할당시키기 위한 캐쉬 분할공간 할당 알고리즘을 제시한다. 여기에서 태스크들이 할당된 캐쉬 분할공간들의 집합을 캐쉬 분할 형태라고 한다. 태스크들이 분할공간에 어떻게 할당되는가에 따라 다양한 캐쉬 분할 형태들을 얻을 수 있다. 이러한 캐쉬 분할 형태들로부터 스케쥴링 가능한 태스크들의 가용비용의 한계범위와 태스크들이 최소 가용비용으로 실행 할 수 있는 캐쉬의 최 적 분할 형태를 분석한다.

이 연구는 청소년의 자율 협력적 독서실행 모형을 제시하고 협력적 독서방식이 청소년의 독서유효성에 미치는 효과를 검증하였다. 이를 위하여 전국 8개 지역, 61개 중 고등학교에 68개 독서클럽을 조성하고 연구집단을 독서미흡집단, 독서양호집단, 독서혼합집단으로 구분하여 청소년의 자율 협력적 독서실행을 4개월 동안 실시하였다. 독서유효성의 설문지를 제작하여 사전과 사후검사를 실시하고 SPSS 통계 프로그램을 통해 분석하였다. 연구 결과, 청소년들의 독서유효성은 긍정적으로 향상되었으며 독서미흡집단이 가장 효과적인 것으로 나타났다. 또한, 청소년의 독서행동에도 긍정적인 변화가 나타났으며 독서유효성의 변화는 독서행동에 영향을 미치는 것으로 파악되었다. This study was to present a model of cooperative reading practice and verify reading effectiveness on youth. For this purpose, 68 reading clubs were established in 61 districts and 8 high schools. The research groups were classified as the poor reading group, the good reading group, and the mixed-skill reading group. The cooperative reading groups were carried out for four months. We developed a questionnaire on Reading effectiveness conducted it pre- and post-test, and analyzed the results through the SPSS statistical program. We found that there was a positive change in the reading effectiveness of youth and overall-the highest effectiveness was found in the poor reading group. In addition, there was a positive change in the reading behavior of youth. The change of reading effectiveness was found to affect reading behavior.

A cyclodextrin glycosyltransferase-producing bacterium was newly isolated from soil using alkaline pH medium containing 1% $Na_2CO_3$. The isolated strain was identified as Bacillus brevis by morphological and biochemical characteristics, and fatty acid composition and designated Bacillus brevis CD162. The strain showed the best enzyme production of 0.9 unit/ml after 96 hrs of culture at $30^{\circ}C$ in a medium of 2.0% soluble starch, 0.75% yeast extract, 0.5% bacto peptone, 0.2% $K_2HPO_4$ 0.05% $MgSO_4{\cdot}7H_2O$, and 1.5% $Na_2CO_3$ at initial pH 10.2. Cyclodextrin glycosyltransferase 생산균주를 토양으로부터 분리하여 형태학적, 생화학적 그리고 균주의 세포벽 지방산 조성분석에 의해 Bacillus brevis로 동정하였고, Bacillus brevis CD162로 명명하였다. 또한 배지조성에 따른 cyclodextrin glycosyltransferase의 최적생산조건을 검토한 결과, 2.0% soluble starch, 0.75% yeast extract, 0.5% bacto peptone, 0.2% $K_2HPO_4$, 0.05% $MgSO_4{\cdot}7H_2O$, 1.5% $Na_2CO_3$ (pH 10.2)의 배지 조건에서 $30^{\circ}C$에서 96시간 배양하였을 때 가장 높은 효소생산인 0.9 unit/ml을 얻을 수 있었다.

The applications developing in distributed object computing enviroments are faced with the difficulties for managing various lots of distributed objects. Also, because the most multimedia service, like video, audio, and so forth, must be satisfied itself with real-time constraints, the users also are feeling with necessary to apply real-time mechanisms to distributed multimedia services. The goal of this paper is to solve the problems for managing distributed objects, and to be easy to develop complex applications that can provide real-time services. To do this, we designed and implemented a real-time object group platform that can be placed between applications and CORBA. This platform is extended the existing object group model[13,14] added to the scheduler and timer object components for supporting real-time concept. We designed the components for platform by using James Rumbaugh object modeling technology that consists of object, function, and dynamic model. And then we described the detailed interfaces of the components by IDL, and implemented our real-time object group's platform using OrbixMT 22 which is the IONA Technologies' ORB product. Finally, we showed the execution procedures of the schduler object of each components in a real-time object group platform.

Objective : The study was designed to identify the factors related to depression of the elderly patients in geriatric hospital. Method : The subjects consisted of 198 old people who admitted in three geriatric hospital located in Daegu City. The Data was collected through interview with questionnaire from July 16 to August 16, 2012. Results : The general characteristics which significantly affected depression was perceived health status(F=18.158, p=.000). There was a slightly negative correlation between activity daily living & depression(r=-.378,p=.000) and strongly negative correlation between life satisfaction & depression(r=-.573, p=.000). Among the factors related to depression of the subjects, life satisfaction had highest expanatory power of 32.8%. Conclusion : The finding of this study provide useful information for constructing an intervention program and care for the elderly patients in geriatric hospital with depression.

The research was carried out to investigate the contamination of stream water by the acid mine drainage originated from the abandoned coal mines and coal waste rock in Keumsan, Chungnam. The pH, sulfate and chemical compositions in the stream water were analyzed. At the polluted sites, the pH of stream water was the strong acid, ranging from 3.46 to 4.29. The pH shows negative correlations with sulfate, manganese, copper, zinc, iron and magnesium concentrations. Sulfate concentrations of the polluted stream water, 236.73 - 310.53㎎/ℓ, had 10 times more than those of the non-polluted stream water. The concentrations of heavy metals, Mn and Fe, in the polluted water were 0.56 - 0.83㎎/ℓ and 5.89 - 10.58㎎/ℓ, respectively. The Mn concentrations were 20 times higher than those of the non-polluted stream water. Compared with those in the non-polluted stream water, the Mg and Ca concentrations in the polluted stream water were high because of leaching from rock and soil to water by the acidifications. Calculated AMDI(Acid Mine Drainage Index) values are low in the polluted stream water, relative to those of the non-polluted water.
