Vibration analysis of through-the-width-split beams for predicting buckling load is investigated based on Euler-Bernoulli beam theory. In split region, each segment is considered as a solid beam. In this region, recurrence equations relating integration constants for adjacent interior regions are established by satisfying continuity conditions at junctions of interior regions. The results of present study are compared with those of experiment and their results give good agreement with each other. From the result, it was shown that local buckling phenomena could appear in fundamental mode, however, there exists load carrying capacity after this phenomena.

Effects of noise from air transporation in Kimhae airport area were evaluated by noise measurement and questionaire. More than 50% of responses showed the complains of speech interference, hearing loss, headache, and loudness interpretation by the time varying noise. The results indicate that the actual location of the measurements is very important in determining the intensity of the noise at a particular distance from the source.

An noise analysis from industrial plants was performed at 450 locations in Pusan and Kyungnam Area. The locations of measurement were divided by the land use of the affected area (e.g., industrial, semi-industrial, agricultural, and green belt area). Nois levels from 158 locations(35%) exceeded the environmental noise standards. The equivalant sound level(Leq) calibrated by background sound level was recorded as 59.89dB(A), 58.93dB(A), 58.59dB(A), and 54.41db(A) at Kimhae-Gun, Buk-Gu, Ganseo-Gu and Saha-Gu, respectively. High levels of noise is generated because the noise from industry is not controlled within its plants and annoyances from the noise that imparts to t he environment is not concerned. An environmental noise standards should be set forth to regulate not only existing industrial plants but additional construsction as well.

This paper is presented of the stress-strain, volumetric strain characteristics of the Pocheon weathered residual granite soil under drained conditions. A series of consolidated drained triaxial compression tets and isotropic compression tests on specimens were performed. All material parameters of Lade's single work hardening and double work hardening model were determined by using the result tests. Most aspects of the soil behavior measured in the triaxial compression tests were reproduced with good accuracy by the constitutive models. Therefore two medels has been shown to be applicable to weathered residual granite soil.

In recent years there has been a surge of interest among linguists in the phenomenon of presupposition. The definition of presupposition has been attempted to make through the semantic account or the pragmatic account. In terms of the pragmatic accounts, the writer will try to analyze the presupposition of a sentence, with reference to the context in which the speaker and the hearer have a common belief. Finally, the following definition was made: "An utterance A pragmatically presupposes a proposition B iff A is appropriate only if B is mutually known by participants." The idea was to suggest that they can only be appropriately used if it is assumed in the context that the propositions indicated by the presupposition-triggers are true. After the survey of the presupposition-triggers, it can be inferred that the proposition carried by the triggers must belong to the common belief between the speaker and the hearer, and then can represent the old information features. In addition, the common belief was also classified in (56) in this paper. Refering to the cooperative principle and the discourse strategy, the presuppositions of various sentence structures were accounted for, with advantages of presupposition-trigger, within the pragmatic theory. In chapter V, the pragmatic account of presupposition was applied to the proposition carried by the Korean particles [-nun] and [-to], which indicates that the fact can be well explained that the particles [-nun], [-to] and others accompany the presuppositonal features and some of contextual features. In conclusion, it was investigated that the pragmatic account of presupposition is simpler and more inclusive than any other accounts.

中學校 外國 地理學習을 爲한 適正地名의 硏究

徐贊基 慶北大學校 1965 論文集 Vol.9 No.-

It is necessary for geography teachers to choose and teach the important place names from the present texts of foreign geography for junior high school, because these texts are in the tendency of containing too much place names in them. But the teachers are in difficulties in teaching students, not only they do not know the optimum numbers of place names, but also they don't know which the important Place names are. This thesis is a study for the solution to these problems. 1. First: After the examination of all the present texts in use, the list of the average rate of frequency was made. (There are 13 kinds of geography texts.) Second: The questionnaire was sent to the geography teachers who are serving in 500 junior high Schools, and the written opinions necessary to decide the optimum numbers of place names could be synthesized. 2. These results showed that about 500 place names are necessary for the students to learn from the texts in junior high school. 3. These about 500 place names were classified into 3 classes: A class, B class, C class. From these classes, 316 place names contained in A and B class are called basic place names. 4. The analytical study was given to the about 500 place names selected as the optimum numbers, in the order of frequency and claass and kind in their structure.

All the controller design problem for linear time invariant dynamic system boils down to proper selecting the characteristic polynomials and numerator polynomials for concerned input-output relations. The propel selection of the characteristic polynomial is not so difficult, if only stability and response are to be satisfied, but it becomes complicated when robustness issue is added. The CDM could be a solution to this problem. CDM which is developed by Lipatov's conditions for stability and Kessler's standard form is easy to process of the controller design, especially it is more useful when the specifications are the settling time, rising time and overshoot. In this paper was used CDM design a simple but robust controller of the ball and beamsystem. The ball and beam system is highly nonlinear system. And it's linear transfer function used to design the controller. But CDM proved to be a solution to design even if there are some uncertainties like this linearized ball and beam system by simulations.
