본 논문에서는 급속 열처리 공정에서 필수적인 빠르고 정밀한 웨이퍼의 온도제어기법을 제안하였다. Bang- Bang/PID 제어기법은 빠른 온도상승률을 만족하고, 오버슈트와 정상상태 오차를 줄이도록 한다. 즉 초기에 허용 가능한 최대전력을 공급하는 일종의 Bang-Bang 방식의 제어를 하고, 설정온도와 출력에서 측정되는 온도와의 차이가 어느 정해진 범위보다 작을 때 PID 제어를 수행한다. 또한 PID 이득을 정하기 위해 ARX 모델로 식별된 플랜트에 Kappa-Tau 동조법이 사용되었다. 개발된 제어기는 실험용 RTP 장비에 적용하여 그 성능을 평가하였다.

Experience on the construction of several 100-plus-story skyscrapers including Guangzhou West Tower, Guangzhou East Tower, and Shenzhen's KK100 is described considering the increasingly strong development trend of 100-plus-story skyscrapers in China. Difficulties in the construction of 100-plus-story skyscrapers are investigated. Four innovative construction technologies receive detailed descriptions: intelligently and entirely-jacked work platforms, formwork and suspension scaffolding systems ("jacking and formwork systems"), multi-function low-carbon concrete, 5D-BIM ("five-dimensional building information modeling"), and safe and rapid vertical transport, as they have found successful applications in actual projects. Popularized systematically as technical achievements, these technologies will significantly influence the construction of similar projects in the future, and produce more social and economic benefits.

프로토타이핑 시스템 설계에서 프로토타이핑은 실제 모델과 같은 초기 모형을 뜻하는 것으로 개발 초기에 시스템의 모형을 간단히 만들어 사용자에게 제시하여 사용자로 하여금 실제 작동시켜 기능의 추가, 변경 내지 삭제를 요구하도록 하여 시스템을 점차적으로 개선시켜 나가도록 하는 방식을 말한다. 가상 프로토타이핑은 임베디드 소프트웨어 개발 초기단계에서 사용자 혹은 의뢰자의 요구사항들을 효과적으로 추출할 수 있도록 고안된 시스템 요구 및 제약조건 추출 방법론이다. 본 논문에서는 가상 프로토타이핑 기법을 이용하여 멀티미디어 플레이어의 다양한 기능을 시뮬레이션 할 수 있는 가상 프로토타입을 설계 및 구현한다.

Objectives : The purpose of present study was to investigate the effect, safety and tolerability of risperdal sachet(oral solution) with lorazepam tablet versus intramuscular haloperidol and lorazepam injection for management of acute psychotic symptom in the elderly with organic mental disorder. Methods : Total 37 patients who have dementia, medical or physical diseases, associated with acute psychotic symptom were randomly assigned to oral treatment with 1mg of risperdal sachet(oral solution) plus 1mg of lorazepam(N=17) or to intramuscular treatment with 2.5mg of haloperidol plus 2mg of lorazepam (N=20). The change of CGI scores was used for the evaluation of efficacy. Results : Mean score improvements at 15, 30, 60, and 120 minutes after treatment were statistically significant at each time point in both groups(p<0.001) and were similar in both groups(p=0.189). Conclusion : A single oral dose of risperdal sachet(oral solution) plus lorazepam was as effective and tolerable as parenterally administered haloperidol plus lorazepam for the rapid control of acute psychotic symptom in the elderly with organic mental disorder.

To understand the role of small heat shock protein (sHSPs) in rice plant response to various stresses such as the heat and oxidative stresses, a cDNA encoding a 24.1 kDa mitochondrial small HSP (Oshsp24.1) was isolated from rice by rapid amplification of cDNA ends (RACE) PCR. The deduced amino acid sequence shows very high similarity with other plant small HSPs. DNA gel blot analysis suggests that the rice genome contains more than one copy of Oshsp24.1. High level of expression of Oshsp24.1 transcript was observed in rice seedlings in response to heat, methyl viologen, hydrogen peroxide, ozone, salt and heavy metal stresses. Recombinant OsHSP24.1 protein was produced in E. coli cells for biochemical assay. The protein formed oligomeric complex when incubated with Sulfo-EGS (ethylene glycol bis (succinimidyl succinate)). Our results shows that Oshsp24.1 has an important role in abiotic stress response and have potential for developing stress-tolerant plants.

An electrohydraulic (EH) pump-driven closed-loop blood pressure regulatory system was developed based on flow-mediated vascular occlusion using the vascular occlusive cuff technique. It is very useful for investigating blood pressure-dependant physiological variability, in particular, that could identify the principal mediators of renal autoregulation, such as tubuloglomerular feedback (TGF) and myogenic (MYO), during blood pressure regulation. To address this issue, renal perfusion pressure (RPP) should be well regulated under various experimental conditions. In this paper, we designed a new EH pump-driven RPP regulatory system capable of implementing precise and rapid RPP regulation. A closed-loop servo-controlwas developed with an optimal proportional plus integral (PI) compensation using the dynamic feedback RPP signal from animals. An in vivo performance was evaluated in terms of flow-mediated RPP occlusion, maintenance, and release responses. Step change to 80 mmHg reference from normal RPP revealed steady state error of ${\pm}3%$ during the RPP regulatory period after PI action. We obtained rapid RPP release time of approximately 300 ms. It is concluded that the proposed EH RPP regulatory system could be utilized in in vivo performance to study various pressure-flow relationships in diverse fields of physiology, and in particular, in renal autoregulation mechanisms.

본 논문은 반도체 FAB공정의 수율개선 및 예측을 위해 데이터마이닝 기법을 적용한 사례를 소개한다. FAB 공정의 복잡성과 생산현장에서 수집되는 방대한 기술데이터로 인해 기존의 통계적 방법이나 엔지니어의 경험적 분석 방법만으로는 미처 파악하지 못하는 수율 저하 요인이 상당 수 존재한다. 본 논문은 먼저, FAB공정을 마친 웨이퍼에 불량 칩(chip)이 지리적으로 특정 위치에 집중적으로 발생하는 현상을 육안검사 대신 군집분석을 이용하여 데이터로부터 자동 판별할 수 있는 방법을 제안한다. 다음으로 연속패턴분석, 분류분석, RBF(Radial Base Function) 기법을 적용하여 수율 저하의 원인이 되는 문제 장비나 문제 파라미터를 신속, 정확하게 파악할 수 있도록 해 줄 뿐만 아니라 공정 진행 중인 제품의 미래 수율을 예측할 수 있도록 지원하는 방법을 제안한다. 또한 위 기법들을 반도체 FAB공정을 대상으로 국내 모 반도체 회사에서 정보시스템으로 구현한 Y2R-PLUS (Yield Rapid Ramp-up, Prediction, analysis ＆ Up Support) 시스템을 소개한다.

유비쿼터스 컴퓨팅은 우리의 생활양식을 빠르게 변화시켜가고 있다. 그러한 배경에는 IT 기술 고도화와 무선 통신기술 발달로 인한 센서 네트워크 환경이 있다. 유비쿼터스 환경 속 센서 네트워크 구축에 있어서는 기존 네트워크와는 다르게 정해진 규격의 동일 장비의 네트워크가 아닌 정해진 규격의 다양한 장비들 간의 상호교류 속에서 이루어진 다는 것이 다르다. 또한 무선을 통해 정보를 주고 받기 때문에 주변 환경에 따라서 통신을 위한 추가적인 경비가 더 소모되기도 한다. 본 논문에서는 이러한 센서 네트워크 환경 구축함에 있어 효율적인 방안을 제시하고 RapidPLUS를 이용하여 시뮬레이터를 구현한다.

Porphyromonas gingivalis (P. gingivalis) is a major bacterial pathogen that causes periodontitis, a chronic inflammatory disease of tissues around the teeth. Periodontitis is known to be related to other diseases, such as oral cancer, Alzheimer's disease, and rheumatism. Thus, a precise and sensitive test to detect P. gingivalis is necessary for the early diagnosis of periodontitis. The objective of this study was to optimize a rapid visual detection system for P. gingivalis. First, we performed a visual membrane immunoassay using 3,3',5,5'-tetramethylbenzidine (TMB; blue) and coating and detection antibodies that could bind to the host laboratory strain, ATCC 33277. Antibodies against the P. gingivalis surface adhesion molecules RgpB (arginine proteinase) and Kgp (lysine proteinase) were determined to be the most specific coating and detection antibodies, respectively. Using these two selected antibodies, the streptavidin-horseradish peroxidase (HRP) reaction was performed using a nitrocellulose membrane and visualized with a detection range of 10³-10⁵ bacterial cells/ml following incubation for 15 min. These selected conditions were applied to test other oral bacteria, and the results showed that P. gingivalis could be detected without cross-reactivity to other bacteria, including Streptococcus mutans and Escherichia fergusonii. Furthermore, three clinical strains of P. gingivalis, KCOM 2880, KCOM 2803, and KCOM 3190, were also recognized using this optimized enzyme immunoassay (EIA) system. To conclude, we established optimized conditions for P. gingivalis detection with specificity, accuracy, and sensitivity. These results could be utilized to manufacture economical and rapid detection kits for P. gingivalis.
