  • It has come to attention that a risk-assessing organization, that will benchmark a company's safety department, is imperative, following an increase in large-scale SOC-business project, construction of higher-raised buildings, development of underground space; all that have increase accident rates. Having faced problems that arise in firms that demand diversity, complexity and instantaneity, the purpose of the thesis is to arrive at efficient and practical problem-solving means. In order to solve the problems that would surface theoretically during an actual risk assessment, the state of the operation systems of the top five national construction firms having a hazard rate of 0.25 times less than the average rate have been analyzed, while a hierarchal recognition research of the employees who not only function at the operating level but are the practice subjects of a firm, has also been conducted, bringing the main text.

  • 학문적인 연구를 위한 목적으로 사용되는 라반 동작분석법(Laban Movement Analysis)의 핵심은 움직임을 통한 개인의 심리 또는 정서 상태는 내적의도에 의해 외적인 움직임으로 표현되며, 그것은 내면 정서의 상징성을 띠고 있다는 것으로부터 출발한다. 또한 라반동작분석법은 움직임의 대상의 구조가 어떠했는지, 그 구조를 과거 또는 다른 구조와 비교 분석적으로 해석하는데 중점을 두며, 분석된 춤의 문법들은 궁극적으로 심리적·사회적·문화적인 다양한 측면에서 서로의 '관계성' 찾을 수 있는 단서를 제공한다. 또한 춤의 '순간성'으로부터 함의된 시스템용어로 기록의 자원을 제공하고, 그것은 다학적인 연구자료로서 교육적 가치를 지닌다.

  • Supervisory control is an approach based on formal language. it is used to model and control discrete event systems in which each discrete event process is represented as an automation. A supervisor is a generator that switches control patterns in such a way that a given discrete evenet process behaves in obedience to various constraints. A flexible manufacturing cell (FMC) is one of discrete evenet systems. Functions necessary for the operation of an FMC are characterized by operational components and informational compoments. The operational components can be modeled using the finite state machines and the informational components can be modeled using the abstract formalism which describes supporting operations of the cell controller. In this paper, we addressed function required for FMC control specification, software engineering aspects on FMC control based on supervisory control, a concept of event queue for resolving synchronization problem, and complexity reduction. Based on the mathematical model of an FMC. we synthesized the controller by integrating a supervisor for FMC with control specification that specifies event-driven operation of the cell controller. The proposed control scheme is stable mathematically so that the system always behaves on a controlled way even under the existence of uncontrollable events. Furthermore, using an event queue concept, we can solve a synchronization problem caused by the violation of instantaneity assumption of supervisory control theory in real life situation. And also, we can propotype a control software rapidly due to the modularity of the proposed control scheme.
