This study is evaluation of shift-workers’ sleep and social life related to hospital workers’ performance and health. We researched shiftworkers’ sleep, sleeping quality and social relations using a questionnaire method to shiftworkplace scattered Daejeon and Chungnam province. The results of shiftworkers’ sleep are differ from habitual sleep. Social participations of shiftworkerse are interfered partially because of shiftwork. In preference, shiftworker preferred health to others because of physical load of shiftworks. Through result of this study about sleep and social life style, we hope to derive reduction methods of shift work fatigue and education for improvement of employers, for example an physiological and psychological accordance method, an health problem solving method and an social accordance method, etc.

본 연구는 스트레스가 있는 대학생들을 대상으로 CST therapy를 통해 스트레스가 경감되는지 LAXTHA QEEG-8 기기를 통해 뇌파를 측정하였다. CST의 주요 기법으로는 CV4 기법을 사용하였고, 실험군과 대조군으로 나누어 실시하였으며, 통계분석은 SPSS Ver.19 for Window(Kor)를 사용하여 대응 표본 평균검정에서 비모수 분석을 실시했다. 그 결과 CST를 실시한 실험군의 1,2,6채널에서 스트레스가 감소된 것으로 나타났는데, 특히 전두부와 측두부쪽에 효과가 있는 것으로 나타났다. 대조군에서의 스트레스 변화는 일어나지 않았다. The purpose of this study was to investigate the change of stress and EEG through the CST. Methods This study measured EEGs through QEEG-8 equipments whether stress is reduced to university students who stress is through CST. CST's main technique used CV4 technique, Divide into experimental group and control group carried out. Statistical analysis SPSS Ver.19 for Window(Kor) used and conducted Nonparametric analysis on the Paired sample t-test . Result, stress reduced at 1,2,6 channel of experimental group that carry out CST. especially, There was effect of the frontal area and temporal area. Stress change in control group did not happen. Conclusion According to our results, CST is effective in reducing stress.

This study is provide information in the development of energy conservation technologies by means of technological demand survey covering energy market and industrial field among energy-related technologies. For this purpose, we check both the present state of energy technologies and trends of social change in Korea, and then combine social needs with major, bottleneck, and essential technologies required for the future. The range of this study covers the field of industry, kiln, furnace, metal, building, transport, and electricity. For case study, valid 120 companies among the 500 companies selected randomly in the energy data-base of Korea institute energy research (KIER) are considered.

본 논문에서는 카메라 영상으로부터 사각형 형태의 마커를 검출하고 인식하는 방법을 제안한다. 본 논문에서는 사각형 형태의 마커 검출을 위하여 입력 영상을 이진 영상으로 변환하고 객체들의 윤곽선을 추출한 다음에 윤곽선을 선분으로 근사화 한다. 근사화된 선분으로부터 기하학적 특징을 이용하여 사각형을 찾는다. 마커의 사각형 영역을 찾은 다음에는 워핑 기법을 이용하여 사각형 마커 영상을 정사각형 형태로 정규화한다. 마커 영상을 정규화한 다음에는 주성분 분석을 통하여 마커 영상으로부터 특징 벡터를 추출하고 표준 마커에 대한 특징 벡터와의 최소 거리법에 의해 마커의 종류를 인식한다. 인식 실험 결과 마커의 종류가 50개일 때에 최대 98%의 인식률을 얻을 수 있었고 입력 영상에 11개의 마커가 있는 경우에 초당 11.1 프레임의 수행 속도를 얻을 수 있었다. In this paper, we present a method for the detection and recognition of rectangular markers from a camera image. It converts the camera image to a binary image and extracts contours of objects in the binary image. After that, it approximates the contours to a list of line segments. It finds rectangular markers by using geometrical features which are extracted from the approximated line segments. It normalizes the shape of extracted markers into exact squares by using the warping technique. It extracts feature vectors from marker image by using principal component analysis. It then calculates the distance between feature vector of input marker image and those of standard markers. Finally, it recognizes the marker by using minimum distance method. Experimental results show that the proposed method achieves 98% recognition rate at maximum for 50 markers and execution speed of 11.1 frames/sec for images which contains eleven markers.

Purpose The Purpose of this study was to investigate the effects of additional limitations during walking on cardiopulmonary functions. The results can be used as basic value for studying of relative on lower extremity problem. Methods Ten healthy female college students, none of whom had gait abnormality, were participated in this experiment. Subjects walked on a treadmill at comfortable walking speed(3.62km/h) under three conditions. Three conditions were First group is without a knee immobilized and crutches(N;normal gait), Second group is with a knee immobilized(C;cast), and Third with a knee immobilized and crutches(CC;cast+cruch). RER, VO2, Kcal, VE was measured by K4b2 and body composition by Inbody 570. The effect values were used mean value of that SPSS(ver. 18.0) in performance of all statistical analyses, statistical significance was set at 0.05. Results Measures increased under three conditions, but significant differences existed in VO2, Kcal. Also, Significant differences existed in CC group compared with N group and C group. Conclusion Knee immobilization and using crutches increase energy expenditure during level walking at comfortable walking speed(3.62km/h) than knee immobilization and normal. Therefore, This fact must be considered during gait training and exercise.
