Bellows is a familiar component in piping systems as it provides a relatively simple means of absorbing thermal expansion and providing system flexibility. In routine piping flexibility analysis by finite element methods, bellows is usually considered to be straight pipe runs modified by an appropriate flexibility factor; maximum stresses are evaluated using a corresponding stress concentration factor. The aim of this study is to develop a bellows finite element, which similarly includes more complex shell type deformation patterns. This element also does not require flexibility or stress factors, but evaluates more detailed deformation and stress patterns. The proposed bellows element is a 3-D, 2-noded line element, with three degrees of freedom per node and no bending. It is formulated by including additional 'internal' degrees of freedom to account for the deformation of the bellows corrugation; specifically a quarter toroidal section of the bellows, loaded by axial force, is considered and the shell type deformation of this is include by way of an approximating trigometric series. The stiffness of each half bellows section may be found by minimising the potential energy of the section for a chosen deformation shape function. An experiment on the flexibility is performed to verify the reliability for bellows finite element.

「金鰲新話」의 創作動機 究明을 위한 一試論 : 「題金鰲神話」의 記號論的 分析을 中心으로 The Motive of the Writing of 'Kumo Shinhwa' based on Semiotic Analysis of 'Jae Kumo Shinhwa(題金鰲神話)'

The object of this study is to try to reveal the motive of the writing of 'Kumo Shinhwa' by considering space as a language of secondary modelling system and analyzing how it functions in the text of 'Jae Kumo Shinhwa'. In order to verify the practicability and effectiveness of this study, I tried to realize what the connotative meaning of those key words in-moon, lamp, perfume, window, plum tree, pine tree-which the author most frequently used by tracing the transformations of their codes from priamry language to secondary. The basis of Semiotics lies in the 'differences' deriving from binary oppositions. I surveyed the dimensions of space using this system and found that they divide vertically and horizontally, and they again divide into oppositions by double-breakdowon-above, middle, below or inside, frontier, outside. And I noticed that such a space can be related to pluralized concepts-sacred and profane, physical and mental, present and transcendent or positive and negative in value-system. Through this study I have reached the conclusion that 'Jae Kumo Shinhwa' is the presentation of artistic life of the author who, in dilemma between real and ideal, sacred and profane world, tried to move from downward space to upward, and I think he wrote 'Kumo Shinhwa' to lead such artistic life of his even in fiction.

A strengthening technique for reinforced concrete beams using external unbonded reinforcement offers advantages in speed and simplicity of installation over other, established, strengthening techniques. The purpose of this paper is to investigate the capabilities of a new retrofitting technique, namely external prestressing(Bow), for flexural strengthening of beams. The paper provides a general description of structural behavior of beams strengthened using the technique. Results of 2 physical tests on strengthened reinforced concrete continuous beams are reported and compared. It is shown that the technique can provide greater strength enhancement to lightly reinforced sections and that provision of deflectors enhances efficiency.

The purpose of this study is to develop appropriate science teaching models which can be applied effectively to relevant situations. Five science teaching models; cognitive conflict teaching model, generative teaching model, learning cycle teaching model, hypothesis verification teaching model and discovery teaching model, were identified from the existing models. The teaching models were modified and in primary and secondary students using a nonequivalent pretest-posttest control group design. Major findings of this study were as follows: 1. For teaching science concepts, three teaching models were found more effective; cognitive conflict teaching model, generative teaching model and discovery teaching model. 2. For teaching inquiry skills, two teaching models were found more effective; learning cycle teaching model and hypothesis verification teaching model. 3. For teaching scientific attitudes, two teaching models were found more effective; learning cycle teaching model and discovery teaching model. Each teaching model requires specific learning environment. It is strongly suggested that teachers should select a suitable teaching model carefully after evaluating the learning environment including teacher and student variables, learning objectives and curricular materials.

「法人稅와 所得稅의 統合課稅方案에 관한 硏究」

This study investigates quantitatively the problems which the current corporate income tax system of our country has. It analyzes, reviews them, and attempts to depict the method of integrating taxation of the corporate income tax and personal income tax as a more advanced method. As the problems which all the current income tax has are investigated, mathematical verification model is set up. Next, tax effect on corporate income is measured and reviewed according to the tax rate structure and tax method of the current corporate income tax and personal income tax. As a result, it is clear that the inequitable and unreasonable income tax burden takes place among the different income classes. In other words, the low-income stockholders are receiving relatively more dual taxation than the high-income stockholders. The high-income stockholders are imposed relatively lower income tax burden than the low-income stockholders. The higher the income is, the lower the rate becomes, Therefore, this results in lower income tax burden than the corporate income tax doesn't tax, and it would be undertaxation. According to the current tax system, tax revenues shortage phenomena happen more than the corporate income tax system is put into operation, and national budget will become undesirable. These phenomena lead to back the income tax system ideal that equilibrium taxation which should be taxed ability to pay principle is realized. Consequently, the current corporate income tax and personal income tax system is contrary to the income tax system ideal, and it should be cultivated. Now, writer shows the method of integrating taxation of the corporate income tax and personal income tax as an improved method. Among those methods, writer would like to point out two methods; 1) paper-distribution-of-corporate-profits approach 2) corporation-tax-credit approach. The one is unitary integrating taxation method, the other is two stages integrating taxation method. These two methods are the same in real contents, but they can be differentiated nominally or formally. When these two methods of integrating taxation are carried out, there are differences in the convenience of tax payment fund or in the time of tax burden. In order to solve such problems, corporate-tax-credit approch is better than paper-distribution-of corporate-profits approach. That is to say, when the corporate income tax and personal income tax are integrated, two stages integrating taxation method is more favorable than unitary integrating taxation method.

法人稅에 대한 重複課稅現象의 檢證

宣炳完 全北大學校 1980 論文集 Vol.22 No.-

It is cristal clear that in most countries a corporation income tax has been imposed on corporate profits, in combination with the individual income tax on the dividends paid from the same corporate profits. Nevertheless arguments pro and con concerning the present corporate income tax system have been discussed in detail. Argument against the present corporate income tax hold that it results in inequitable and undesireable dual taxation on the dividends paid out to stockholders on which the corporate tax has already been imposed. On the other hand, the arguments in favor of the corporate income tax is based on the Real Entity Theory. According to this theory, a corporation is entirely separate economic as well as legal entity independent of its individual components, viz, stockholders. Accordingly, the purpose of this research is to establish the mathematical research model in order to search for the above two theories and testify the double taxation-in terms of current corporation tax and income tax in Korea. The findings are : (1) Double taxation on corporate profit, in general, rather is smaller than are not taxed. Rather double taxation exists under specific condition, whole amount dividends system. As arguments against the corporate income tax, the opinion which corporate tax should be abandoned or arranged or combined in corporate income tax, is not realistic and inaccurate theory but only a theoritical idea, because corporation tax on corporate income and income tax on dividend after corporation tax reduction are overlaped. (2) The separate imposition of the corporation tax will cause double taxation for the lower income stockholders and the other hand higher income stockholder pay rather smaller amount of tax, as a result. Therefore the taxation is badly unfair in this case. Accordingly, a corporation in modern society is superior in terms of managerial organization, capital budget and managerial ability to individuals, and it is in the saddle. So the opinion of argument in favor of corporation tax sounds reasonable as shown, but it encompasses self-contradiction. How come? Even if Real Entity Teeory and corporation tax is reasonable, it is general and ideal income tax system to impose fair tax or impose taxes on a graduated scale according to principle of fair taxation to the people who receive corporate income as dividend. But dual corporation tax by current corporation tax system leads to the opposite results. (3) The argument against corporation tax based upon Finction Theory and the argument in favor of corporation tax based upon Real Entity Theory looks like two sides of coin. We can not take one side and abandon the other. (4) Corporation incme tax is imposed in West Germany, France, America, Canada, Japan as well as England now. Each country take into account of adjusting taxation system in an attempt to omena, double taxation. We have been based on Real Entity Theory. In the wake of this phenomena, double taxation is inevitable, but we, in Korea, have to arrange the taxation system. I urge to improve the current corporation tax and tax rate of income tax to be fair taxation and graduated taxation in accordance with different incomes of stockholders. As above, I tesified statistically double taxation phenomena in term of corporation income. I would like to argue to improve the problem and contradiction of current tax rate and tax system on corporate source income.

The study was designed to investigate the anxious and depressive trends in the wives of alcoholic patients. For the purpose of assessment of anxiety and depression, Zung's self-rating anxiety-(SAS) and depression scales (SDS) were applied to the fifty wives of alcoholics, the latter were admitted to the psychiatric wards of Taegu Catholic Hosp. and Kyungpook National Univ. Hosp. from Jan 1 '84 to Sep. 30 '85 and were diagnosed according to DSM- criteria. And the two scales were also applied to the fifty wives of social drinkers as a control group. The results were as follows; 1) The mean SAS scores were 53.06±9.66 in the wives of alcoholics and 38.64±8.75 in the control group and so the difference was significant in anxious trends (p<0.01) between two groups. 2) The mean SDS scores were 54.00±10.20 in the wives of alcoholics and 42.64±7.80 in the control group and so the difference was significant in depressive trends (p<0.01) too between two groups. 3) As for the frequency order of the SAS items in the wives of alcoholics, they were apprehension, insomnia, restlessness and fear. As for the frequency order of the SDS items in the wives of alcoholics, they were confusion, decreased libido, decreased appetite and psychomotor retardation. 4) As for the wife's attitude toward her husband, nagging and interfering attitude was commonest(46%) in the wives of alcoholics in contrast to the gentle and tender attitude(48%) in the wives of social drinkers. 5) 62% of wives of alcoholics were dissatisfied with their sexual life but the degree of dissatisfaction was low to 8% in the wives of social drinkers.
