        A hierarchical algorithm for the optimal control of large scale discrete tune systems with time-delays is proposed The proposed algorithm which is based on the interaction prediction method can be applied to a large scale time-delay systems with general structure by extending the dimensions of coupling matrices. A numerical example illustrates the algorithm.

        배수관 내시경 조사를 통한 간접적인 관 노후도 평가방법의 적정성 연구

        최태호,강신재,최재호,구자용 대한상하수도학회 2012 상하수도학회지 Vol.26 No.5

        The water supply pipes are buried across wide range of areas, so it is hard to spot them using excavation and takes a large amount of expense. Thus, there is a high risk for direct research and application, accompanying many difficulties in implementation of them. Therefore, it is more economical and convenient to use indirect evaluation variables than direct evaluation of the buried pipes in assessing the degree of pipe deterioration. To assess the degree of pipe deterioration using the indirect evaluation variables, it should be done first to identify how and to what extent they affect the degree of deterioration. This study measured the evaluation variables for pipe deterioration using the pipe endoscope and analyzed the measurement results and the degree of impact on the pipes. In addition, this study attempted to evaluate the adequateness of the pipe deterioration evaluation using the indirect variables based on the analysis results. The evaluation variables measured through the pipe endoscope were the thickness of sediments, size of scale, degree of desquamation and condition of connections. For the indirect evaluation variables, the data such as the property data from GIS pipe network map as well as the material, diameter, age and pipe lining material of the pipe, road type, leakage frequency, average water velocity and water pressure using the leakage repair records was collected. Using the collected data, this study comparatively analyzed the indirect evaluation variables for the degree of pipe deterioration and the results from the pipe endoscope to choose appropriate variables for pipe deterioration evaluation and calculated the weights of the indirect variables on the degree of deterioration. The results showed that the order of the impact of indirect variables on deterioration was pipe age > pipe lining material > road type > leakage frequency > average water velocity with their weights of 0.45, 0.20, 0.15, 0.10, and 0.10, respectively. Conclusively, the results suggest that the measures of sediment thickness, scale size, degree of desquamation and condition of connections are appropriate for the evaluation of pipe deterioration and sufficient for the analysis of the impact of the indirect variables on deterioration.

        외식 O2O 서비스 품질이 신뢰와 지속적 이용의도에 미치는 영향:배달 어플리케이션을 중심으로

        최태호,이명철,김동섭 (사)한국조리학회 2020 한국조리학회지 Vol.26 No.7

        The purpose of this study is to examine the relationship between the impact of O2O quality of service on trust and the intent of continuous use. In order to achieve the purpose of this research, residents in their 20s and 40s or older living in Seoul and Gyeonggi-do were selected for the survey and conducted from June 1 to July 5, 2020. The collected data were analyzed using SPSS 22.0. The results of this study show that first, the lower factors of O2O service quality: in-convenience, immediate access, stability, economics, and empathy have a significant positive influence on trust. Second, the lower factors of O2O service quality were convenience, immediate access, stability, economics, and empathy, which had a significant positive influence on the intent of continuous use. Third, trust has been shown to have a significant positive influence on the intent of continuous use. We examined how the quality of delivery application service, which is being used most actively among O2O services, affects consumer behavior, and based on this, we planned to develop a plan for improving the quality of delivery application and to increase the consumer's continuous use.

        한국어 교사 양성제도 및 지도방법 연구

        최태호 한국국어교육학회 2009 새국어교육 Vol.0 No.82

        본고는 제2언어로서 한국어 교육의 교수 방법과 교사 양성과정 및 교재에 관해 분석적으로 연구하였다. 많은 교수법이 있었지만 언어교육에 있어서 왕도는 없다고 본다. 단지 필자가 그 동안 해 왔던 교수법을 통합적 개인교수법이라는 이름으로 文法飜譯式 敎授法과 相談, 個人敎授法 등을 통합하여 실시하고 있는 방안을 체계적으로 정리하였고, 교사 양성과정에 있어서는 현재 대학원중심으로 한국어 교사를 양성하고 있는 것을 보고 학부 중심의 교육이 필요함을 피력하였다. 학부보다 대학원에서 교사를 양성하는 기형적인 제도를 보완하여 정비하고 학부과정을 심도 있게 할 것을 고찰하여 제도적 장치를 완비해야 함을 밝혔다. 다문화 가정에 대한 한국어 교사의 문제를 지적하였다. 아울러 한국어 교재의 경우 유학생 중심으로 되어 있는 교재를 분야별로 다양하게 만들어야 하는 필연성을 고찰하였다. 근로자를 위한 교재나 여성결혼이민자를 위한 교재가 이직은 초보 단계에 있음을 보고 교재 개발의 중요성을 고찰하였다. This study aims to make a method of Korean as a second language, and analysis to textbook for intermediate learners. And the purpose of this study is to provide some principles of immigrated women's Korean language textbook. There are many teaching method, Grammar translation method, Audio - lingual method, Communicative Approach and so on. But I discussed from a different point of view, it was a unitive tutorial method.. The point of unitive tutorial method is all previous educational method plus Confucius tutorial way. Second, KSL(Koeaan as a second language) teacher have to educated by university major part. Because they need a high level knowledge.(language, culture, history and so on). And it is the time of Multi- culture. So many women who came from many nations live in Korea. The teachers who teaches immigrated women are almost volunteers, so they not professional KLS teacher. Therefore we have to make institutional equipment.
