조가선 이상 장력 작용에 대한 전주의 영향 및 보호 대책 연구
오훈,Oh, Hun 한국조명전기설비학회 2006 조명·전기설비학회논문지 Vol.20 No.3
본 연구에서는 통신선 가설 보조 기구인 조가선에 이상 장력이 작용하였을 때 전주의 영향을 유한 요소 해석을 통하여 전주 보호 기구를 설계 해석하여 보호시스템을 개발하였다. 보호시스템은 일반하중 또는 풍압과 일반적인 불평형 하중에서는 조가선이 탈락되지 않고 일정강도 이상이 가해지면 조가선이 자동 탈락되어 전주의 절손 방지 역할을 한다. 이러한 보호시스템의 구조는 유한 요소 해석을 통하여 해석되어졌고, 실제 제품에 대한 인장강도를 측정함으로써 성능을 입증하였다. In this study, we analyzed the influence or electrical pole by FEM(Finite Element Method) and developed protective system by designing and interpreting protective system for electrical pole when abnormal strength worked on messenger wire. Protective system did not shed messenger wire under wind pressure and discontent load but did assign a part to preventing rupture of electrical pole through automatically shed messenger wire over fred strength. Structure of protective system analysis by FEM and prove property by measuring tensile strength for practical product.

In terms of income level and purchasing power, it is predicted that the elderly will emerge as a leading consumer class, not the underprivileged class of the past. This study attempted to find out how tourism constraints and tourist destination selection attributes affect tourism behavior through empirical analysis of elderly tourists aged 60 or older. To this end, a survey was conducted by 500 elderly people with travel experience within the last year, and 274 samples suitable for research purposes were used for analysis. Descriptive statistical analysis, frequency analysis, reliability analysis, exploratory factor analysis, regression analysis, and one-way variance analysis were used as analysis techniques. As a result of the analysis, it was found that there was a negative (-) causal relationship between internal and attractive factors among tourism constraints. In contrast, positive (+) effect on tourism behavior was discovered on both experiential and attractive factors among tourist selection attributes, and internal and personal constraints among tourism constraints. The implication of the study is that elderly tourists show different characteristics from ordinary tourists, so the differences between their constraints and optional attributes should be carefully reviewed when establishing elderly tourism policies.

It is needed to robust control for D.C. servo motor according to industrial automation. However, when a motor has an effect of disturbance and variable load, it is very difficult to guarantee the robustness of the system. as a compensation way of solving this problem, in this paper, a expert supervisory control method for motor control system is presented. Expert supervisory controller is designed by error and error change, and nth control input is decided by the addition of (n-1)th control input and inference amount of increase or decrease. Control input of expert supervisory control is transmitted to input, and the disturbance effect decrease remarkable by control input. The robustness of D.C. servo motor using expert supervisory control is demonstrated by the computer simulation.
