  • A practical model for predicting the risk of fatigue failure of steel highway bridges is developed in this study. The proposed model is derived from fatigue reliability methods by incorporating various factors which may affect the fatigue life of bridges. The fatigue reliability function is assumed to follow the Weibull distribution. The computational form of the Weibull is adopted from Ang-Munse's approach that includes all the statistical uncertainties of the fatigue life of steel members and the stress ranges under variable amplitude loadings. The model accounts for the variation in ADTT, the change in stress history and the effects of inspections, which may occur during the serivce life of bridges. Stress range histograms are collected from the random stress spectra based on the field measurements of an existing bridge, and, thus, the resulting stress range frequency distribution is modelled with a beta distribution. The results of applications of the proposed fatigue analysis methods to an existing bridge show that the proposed models with the computer program developed for numerical computations can be used as a practical tool for the fatigue rating or for the predictions of the remaining fatigue life of deteriorated existing steel bridges.

  • In our country, nation-wide forest road works are being carried out as one of the efforts to bolster the international competitiveness of agriculture, however such environmental problems as sediment discharge and water quality degradation accompany such efforts more often than not. Hence, in this research report, we compile and analyze the Japanese sources dealing with the "research direction of the forest road construction", "environmental impact assessment upon the watershed of the forest road construction", "environmentally-sound forest road construction and its research method" in consideration of the fact that natural environment of Japan is similar to that of our country and Japanese forest road works has a long history. We hope that this report be useful to the reasonable watershed management and the environmentally-sound forest road works.

  • Well organized design based education is the one of the best way to develop the abilities needed for the engineer such as the recognizing and formulating a problem and then solving it creatively and systematically. In order for this, we prepared a course named 'Introduction to the Engineering Design' for the first-year students, which aims at developing creativity and ability to promote a project. Experiment-design mixed courses and theory-design mixed courses, where students have to solve various design problems, are provided for the higher grade students. In this paper, we are focused on the experiment-design mixed course for the second-year students which has been operating from two years ago. Here we show how the teamwork ability is improved. We also present how to operate the course in detail so that anyone can easily get the way to reach the outcomes needed for the engineers.

  • This study proposed to assess courses which are currently offered in the Department of Library and Information Science, and to explore directions for improvement. Based on field librarians' needs and opinions about the courses, we suggested separating the required, core, and elective courses. We proposed six courses including 'Internship', 'Introduction to Library and Information Science', 'Cataloging and Classification', 'Library Management', and 'Information Retrieval' as required courses, and 5 courses including 'Practice in Cataloging and Classification', 'Information Resource and Service', 'Collection Development', 'Digital Library System', 'Introduction to Bibliography' and 'Records Management and Archives' as core courses. Finally, the remaining courses were recommended as selective courses which each department could select depending on their circumstances and faculty. The important components for substantial LIS courses are as follows: timeliness of training topics, expertise of educational contents, professionalism and qualifications of faculty, specialized educational materials, and increasing the major correlation between courses and professors.

  • The importance of business ethics has been increased as time goes on. However, there are lacks of education and research in business ethics, domestically and internationally. Especially, in Korea, there are not many universities which teach business ethics as formal curriculum and there are not sufficient researches on business ethics. Also, the level of education of business ethics is only restricted to the type of case discussion and research of business ethics is focused only on one topic, corporate social responsibility which is only one of various and important topics in business ethics. Accordingly, as a qualitative research, this paper presents some directions that are essential to education and research in business ethics, discusses what has been educated and researched in business ethics, and proposes what are necessary for the future of education and research in business ethics. Based on this research, various researches which investigate various topics in business ethics are possible in the future.
