Objectives: The aim of this study was to analyze the change of lateral shift of Center of Pressure (CoP) according to the gait improvement in post-stroke hemiplegic patients and to investigate relationship between the change of motor grade and lateral shift of CoP. Methods: We measured the lateral shift of CoP and motor grade of eight post-stroke hemiplegic patients at the beginning of dependent gait and independent gait. Results: We found that CoP tended to be shifted to the non-affected side when patients started to walk independently. Furthermore, there was no relationship between the change of motor grade and lateral shift of CoP. Conclusions: This result may suggest it is more important to control the non-affected side than the affected side, at least until the beginning independent gait.

본 논문에서는 열간압연 ROT 공정에서 고강도 내후성강을 대상으로 압연 강판의 길이방향의 온도와 재질을 제어하기 위하여 독립냉각제어(ICC) 라는 새로운 제어개념을 제안하였다. ROT 공정을 전단냉각 및 후단냉각으로 분리하였으며, 각각의 독립공정에 대하여 온도제어 모델을 개발하였다. ICC 제어는 열간압연 공장의 온라인 데이터, 제어상의 문제점 및 내후성강의 TTT 선도로부터 도출하였다. 제안된 ICC 제어의 알고리즘은 변태발열에 의한 온도 외란을 이용하여 타당성을 검증하였다. 또한 열연공장에서 온라인으로 테스트 결과 강판의 온도제어 정도가 향상되었음을 입증하였다.

The purpose of this study was to review the current studies on community attachment and its related variables to suggest directions for community attachment studies in Korea. Specific objectives of the study were to search the current studies on community attachment, to search for the significant variables related to community attachment, and to draw implications for community development in Korea. The major findings of the study were as follows; 1) Current studies on community attachment used individual characteristic variables such as length of residence in the community, age, size of population and density as major independent variables. 2) Studies on community attachment used community participation, social and cultural environment as major dependent variables, however, both independent variables and dependent variables were used interchangeably in many cases. 3) Recent studied on community attachment employed community economic and cultural variables, however, studies on community attachment in Korea was relatively limited in terms of quantity as well as quality. 4) Further research on community attachment should be conducted by utilizing various independent and dependent variables in various communities to increase the community attachment in rural and urban communities to further strengthen community development in Korea.

According to U.S. NTSB, from 1989 to 1992, Situation Awareness(SA) was a major factor causing 80% of all aircraft accidents in scheduled airlines. Therefore, the prevention of accidents through effective training in SA became a pivot in aviation safety. Furthermore, during the past 10 years, since all helicopter accidents in Korea were caused by the factors related to SA, an appropriate countermeasure has been required. This study, which uses survey data, examines various factors related to SA that could affect helicopter pilots. Common characteristics of situation awareness factors are that the result from the independent variables which are flight time, duty period and age of a first officer is statistically significant with the result from the independent variables of an instructor pilot's. However, only experience is statistically significant independent variable for factors influencing decision making in emergency situations, but anxiety, expectation and comprehension are not significant.

We examined the associations between adiponectin or leptin and serum ICAM-1 levels in seventy-six hypercholesterolemic patients (mean age 59 yrs, 25 males and 51 females, LDL-cholesterol>=130mg/dL at screening). Blood lipid profiles and HOMA-IR derived from fasting glucose and insulin concentrations were determined. Serum levels of adiponectin, leptin and ICAM-1 were analyzed using ELISA The results showed that serum levels of leptin were positively associated with serum levels of ICAM-1 independent of age, sex and BMI (r=0.392, p<0.001). Serum levels of adiponectin were negatively associated with serum levels of ICAM-1 independent of age, sex and BMI (r=-0.343, p<0.005). Stepwise multiple linear regression analysis showed that serum leptin was an independent factor to be associated with serum ICAM-1 levels after adjusting for age, sex, BMI, alcohol intake, smoking status, blood lipids such as total cholesterol, triglyceride, HDL cholesterol and LDL cholesterol and HOMA-IR (p<0.001). With respect to adiponectin, its association with serum ICAM-1 was attenuated but still significant when further adjustments were made for age, sex, BMI, alcohol intake, smoking status, blood lipids such as total cholesterol, triglyceride, HDL cholesterol and LDL cholesterol and HOMA-IR (p<0.005). In conclusion, this study suggests that adiponectin and leptin are associated with endothelial derived inflammation.

A brain-computer interface(BCI) system is a communication channel which transforms a subject's thought process into command signals to control various devices. These systems use electroencephalographic signals or the neuronal activity of many single neurons. The presented study deals with an efficient analysis method of neuronal signals from a BCI System using an independent component analysis(ICA) algorithm. The BCI system was implemented to generate event signals coding movement information of the subject. To apply the ICA algorithm, we obtained the perievent histograms of neuronal signals recorded from prefrontal cortex(PFC) region during target-to-goal(TG) task trials in the BCI system. The neuronal signals were then smoothed over 5ms intervals by low-pass filtering. The matrix of smoothed signals was then rearranged such that each signal was represented as a column and each bin as a row. Each column was also normalized to have a unit variance. As a result, we verified that different patterns of the neuronal signals are dependent on the target position and predefined event signals.

최근 TFT-LCD (Thin film transistor liquid crystal display)패널의 수요증가에 비례하여 공정상 발생하는 LCD 불량의 수도 증가하고 있다. LCD 불량은 배경화면과 미세한 밝기대비 차이를 가지는 패널상의 불균등한 영역으로서 크게 정형과 비정형으로 나누어지며 사람의 눈에 매끄럽지 않게 보여진다. 이러한 불량은 배경과의 대비 차이가 미세하여 기존의 임계수준 검출이나 윤곽선 검출로는 불량을 검출할 수 없다. 본 논문은 비정형 LCD 불량을 독립성분분석, 적응 임계수준 검출 그리고 왜도를 이용하여 검출하는 방법을 제시한다. 본 검출방법은 잡음이 심한 영상에 대해서도 대응력이 뛰어나며, 생산라인에서 성공적으로 적용된다.
