  • This paper presents a construction method of logic-based switching control system which operates in widely changing environments. The logic-based switching controller is composed of a family of candidate controllers together with a supervisor. The system does not require any identification schemes of environments. Switching from one candidate controller to another is carried out based on monitoring the output of the system. The basic ideas of adaptation are as follows: (1)each candidate controller is prepared for each environment in advance; (2)the supervisor applies a sequence of speculative controls to a plant with candidate controllers just after the control has started and just after the change of the environment has been detected. It is important that each candidate controller can keep the system stable during a sequence of speculative controls, and the most appropriate candidate controller for the environment to which the system is exposed can be selected before the last speculative control is ended. An application to an antiskid braking system clarifies the effectiveness of the proposed method.

  • This paper aims for a study on the theory that mind is Li(principle). The method of research is laid emphasis on searching for the historical development of the perception Theory in late Cho-Sun. First of all, I investigated a meaning of the perception theories of Ho-Rak school, that were criticized in the Cho-Sun academic world. The next, I investigated the theory of Li-ju-Ki-ja that was raised by Yi Sang Jung. He thought that Li is supervisor and Ki is assistance. And he put a construction on the Perception Theories of Toegye school. Yi Jin sang's theory of perception is the result of criticism against Ho-Rak school, and a fresh and in-depth construction of Yi Sang Jung's perception theory. His viewpoint was contradiction to the theory of Sim si Ki(the theory that Mind is made of Ki). And he rediscovered the human conscience that was born endowed from Heaven.

  • Eventually so as to realize the construction safety, 1 found out the cause of accident and specificities of the construction industry. This study presented to several situations and problems on construction safety. As a result of this study, the below matters must be improved for more effective the construction safety management system. 1. It need to introduce the total construction safety management system. Because there is not effectiveness in the current safety management to the first on the construction field. a. We must consider the safety in the whole parts of the process of the construction and constructors of each part must devide responsibility of the construction safety as a CDM(The Construction Designed Management) used in UK. b. It is desirable to proceed control of safety in the whole parts of the construction to introduce the total safety coordinator that can consult the matters of safety as a law accepted in EU. c. Like management of the construction safety in USA, direction of the construction safety must be made to work exactly by code or manual. d. To improve the organization of the construction safety on the construction field unefficient, it must be introduced safety supervisor, safety coordinator or institutionalization of safety consultant. 2. The law of the construction safety not only have wasteful element but also decrease efficiency by overlapping of regulation, The Ministry of Labour and The Ministry of Construction & Transportation, So laws related with safety must be instituted. a. To realize total safety management, The Ministry of Labour must legislate the basic law about safety management in whole field. b. To legislate the construction safety under one law, and improve efficiency of the overlapping of regulation and the similar law by The Ministry of Construction & Transportation. c. It must be made the law of construction safety that can proper to change of situation in construction. d. The standard of safety must be instituted belong to international level and improved by year. e. We must improve irrational regulation to realize activity of safety self regulating for progress competition in construction industry

  • The government has established various policies focusing on accident prevention to reduce the accident rate in the construction industry, but the effect is still insignificant. These results allude that there are still many problems in terms of usability. Although construction safety accidents usually have characteristics that occur during construction, the laws and systems should include the pre-construction cycle (plan/order - design - construction business management- construction) to eliminate risk factors in advance. The purpose of this study is to analyze the performance evaluation of the construction safety system before construction rather than during construction. In the pre-construction phase (plan/ order-design-constuction business management), we intend to investigate and analyze measures to prevent safety accidents and identify a system that lacks the ability to implement. Specifically, we analyzed what to focus on as precautionary measures in the planning, ordering, designing, and supervising. To improve them, we made a questionnaire based on the role related to construction safety for each subject, and seek implications for lack of performance through interviews. Based on the results, some ways to improve the safety system were proposed.

  • In order to maintain and protect professionalism in color planning, the present study examined the process at the time of realization of color through color inspection and supervision in the actual construction site and suggested plans for improvement. Reflecting the characteristics that the governing body of the construction site is not a private person but an organization, the present study aims to provide institutional measures so that the supervisor of color construction at the actual site of construction can propose concerns related to proper construction at the right time, and the matters cannot be decided from the perspective of a layman. The institutional measures are proposed through the case of application of a process at the construction stage of the color planning at the construction site of Muju Taekwondo Park. First, the process clarified where the responsibility lies by specifying special conditions concerning color inspection on the field guide and color contract. Second, the sample for building materials was selected after obtaining it from a company capable of supply and is appropriate for the planned unit cost so that it could play an important role in realizing colors at the stage of basic design. Third, the process of construction was ensured not by temporary selection of colors but by continuous approval of colors in consideration of the conditions of construction site through letter of approval of color at each stage and point of time. Fourth, coordination of various color elements of other fields including landscape, interior, and electricity ensured construction of the whole structure in one color concept. Fifth, color inspection through the mock up of the site will minimize erroneous construction and reconstruction and prevent decrease in productivity. Sixth, this study also suggested more comfortable and positive color environment through evaluation by experts and users. The researcher of this study expects that color experts actively participate in the stage of construction to contribute to improvement of the color environment.

  • The Dismantlement and Construction of the buildings have the characteristic of floating change with repetition within a Time Schedule which has fixed resources, that is, Manpower, Materials and Equipments, and involve many disaster factors in performing each processes. But as these factors are variable, a work supervisor should be able to understand data analysed distinctive factors of each activities systematically, organizationally, and scientifically, and diagrammatic information media so that he can control any complex and situation beyond forecast. Thus this study is intended to be a barometer of weighing if the existing process schedule has taken security into consideration by making the characteristics of organization and action of Work package per process in a building field with more factors like these into a network system and is intended to minimize construction disasters by systematizing this into a Transformational Network.
