본 논문에서는 카메라-투영 시스템에서 비전에 기반을 둔 손동작 인식을 위한 새로운 알고리즘을 제안하고 있다. 제안된 인식방법은 정적인 손동작 분류를 위하여 푸리에 변환을 사용하였다. 손 분할은 개선된 배경 제거 방법을 사용하였다. 대부분의 인식방법들이 같은 피검자에 의해 학습과 실험이 이루어지고 상호작용에 이전에 학습단계가 필요하다. 그러나 학습되지 않은 다양한 상황에 대해서도 상호작용을 위해 동작 인식이 요구된다. 그러므로 본 논문에서는 인식 작업 중에 검출된 불완전한 동작들을 정정하여 적용하였다. 그 결과 사용자와 독립되게 동작을 인식함으로써 새로운 사용자에게 신속하게 온라인 적용이 가능하였다.

The objective of this numerical study is to investigate the effect of the shape and material of the blower blade for the electrified speed sprayer on the blowing performance. The shape of the blade was changed to the bonding angle, the number of blades, the width of the blade, and the blade length based on the existing model. In order to obtain the reliability of the numerical model, the analysis of the grid dependence was performed in the numerical analysis. The numerical analysis results were compared and analyzed in terms of the agricultural chemical penetration length characteristics, flow uniformity characteristics, and velocity distribution characteristics. Furthermore, the effect of material change on weight reduction and structural characteristics was also compared and analyzed. As a result of the analysis, it was found that the optimal condition was that the blade angle was 45º, the number of blades was 12, and the width was 115 mm, which was confirmed through a comparison of the inlet mass flow rate. As a result of the equivalent stress lower than the yield strength due to the material change from aluminum to steel compared to the existing steel, structural defects do not appear, and it is judged that the operation time compared to the battery capacity will be improved through the weight reduction of the blade.

In this present study, the long-term consolidation tests were performed using the remolded Kwang-Yang port clayey soil to clarify the effect of stress history and over-consolidation ratio (OCR) on the long-term consolidation characteristics of the soft clayey soil. For the over-consolidated state clayey soils, in case OCR exceeds 1.5, there are no great differences of secondary consolidation settlement and final settlement even if OCR increases from 2.0 to 3.0. Therefore, it has been understood that the value of OCR applied on the field site to reduce the secondary consolidation settlement and the final settlement is about 1.5. In addition, in order to investigate the relationship between the pre-loading period and the characteristics of long-term consolidation behavior obtained from the test results using the remolded Kwang-Yang port clayey soils, the influence on long-term consolidation behavior was not large though the pre-load was unloaded with the consolidation degree 70~80% exceeded.

This study sets it’s face to define effects of the various loading periods in normal consolidation area on clay’s compression and long-term consolidation characteristics through a laboratory test using homogeneous remolded clay. Moreover, by carrying out a long-term consolidation test which diversifies initial consolidation applicable to effective overburden loading in the various loading period. This study intended to suggest the method predicting the final settlementon the basis of loading periods by comparing and analyzing compression curve’s characteristics according to loading weight of each stage and increase in loading period when carrying out the standard consolidation test. From the testresults, the study shows that as of the soft clay’s compression characteristics on the basis of various loading periods, preconsolidation load has a tendency to be decreased slightly as the loading period is getting more and more longerat each step after initial consolidation load puts on the remolded clay which is caused by secondary consolidation’s increase in the latter part of each phase. And those effects have an weaker influence on compression index in normalconsolidation area at the same time as secondary consolidation brought out quasi-overconsolidation and stabilization of clay’s structure, have an influence re-compression index is increased in overconsolidation area on the other hand.

In this paper, we analyze the necessity of applying Electronic Stability control(ESC) based on the vehicle stability field of test for compact vehicle. As a result of the test, it was confirmed that the lateral acceleration and yaw rate were high when the ESC was not applied, resulting in inability to control the yaw rate and the lateral acceleration, which was insufficient to secure driving stability. Research on the application of the vehicle stability control system for compact vehicles should be continued, and based on the above test results, it is believed that research on establishment of suitable safety standards for compact vehicles should be conducted as soon as possible.
