For the development of a good rainfall-runoff model, the estimate of the parameter of Storage-Function Model(SFM) and HEC-1 are compulsory. It is concluded that SFM can consider model for the real-time control of a multi-purpose reservoir in case of storm event on subbasin area. For the parameter of SFM and HEC-1 on 3 watersheds In Hapchen dam. It has been computed to calibrate by the iteration method using the observed data of the storm event and the discharge at 1998 year. The value of the estimated parameter on HEC-1 was analyzed by the linear regression analysis of computed and observed discharge. The results obtained in this paper are summarized as follows; 1) SFM is good for the hydrograph on subbasin in Hapchen dam by the linear regression analysis of computed and observed discharge which has been 8 storm events. 2) The coefficient of determination and standard error of the parameter of SFM are about 0.88∼0.99, 0.16∼5.12. The lag time(TI) and ratio of runoff are about 1∼2hr, 50%. 3) For comparison with the value of the coefficient of determination, HEC-1 is lower then SFM on the peak of computed and observed discharge. 4) The parameter value of K, TI of HEC-1 are about 4.01∼19.13, 5.73∼21.81 in Gechang-Ⅰ, 7.17∼20.82, 7.94∼20.78 in Gechang-Ⅱ, 0.52∼18.34, 4.62∼19.11 in Jisan.

新古典學派의 分配理論에 대한 批判的 考察

李容旭 대구효성가톨릭대학교 1978 연구논문집 Vol.20 No.1

There are three important problems in the marginal productivity theory. (1) the so-called 'adding-up' problem. (2) the problem of the definition of factors of production. (3) the assumption of perfect competition. The first problem is settled b assuming the constant resurn to scale. The first and the third are brought forward in the context of whether they have any relevance to economic reality. But as for the second, particularly it is assocated with whether we can difine the quantity of capital independent of income disribution. This article is a study on how this second problem shakes the fundamental postulates of the Neo-classical theory and its theory of distribution. It is necessary clearly to appreciate the reason why the Neo-classical macro-distribution theory ends with failure to provide us with a testable theory of the national income into usch large aggregates as profits and wages over historical time. The marginal productivity theory is merely and extension of the profit-maximisng theory of the firm and the macro=distribution theory is constructed by analogy with the corresponding micro-distribution theory. The profit maximising theory of the firm corresponds to the utility maximisng theory of the consumer. But in the classical theory, the value theory is to provide us with a consistent measure of the surplus to be distributed and to explain what determines the relative exchange value. In the Neo-classical theory, the theory of surplus to be distributed is integrated to the theory of relative value by reducing the theory of surplus distribution to the theory of pricing factors of production. The theory of pricing factors on market is based on the theory of the demand for and supply of the factors of production. The reason for the failure of the Neo-classical of macro-distribution lies just in identifying the theory of value with the theory of relative value and averting from the aspect of the absolute measure of value in the theory of value. This identification brings to restrict the subject of the economics to the problem of rational choice among alternatives. To put in another way, it wrenches the value theory from the macro-economic scope to the micro-economic sphere. Such a kind of wrench again appears in constructing the macro-distribution theory of the Neo-classical economics by analogy with micro-theory. From this point of view, here it is examined how the Neo-classical theory of distribution meets difficulties. Here the difficulties mean the problem of measuring capital, the meaningless of distinction between shifts of and movements along a aggregate production function, the so-called "reswitching" of the same technique and the capital reversing. In particular, we examine the critical meanings of Sraffa's system to the Neo-classical theory distribution. What this article shows amounts to this, that (1) the problem of measuring capital is not simply a kind of index problem, or of aggregating problem, but is associated with the social relation which is characteristic of capitalist economy, (2) the distinction between shifts of and movements along a aggregate production function is meaningless, (3) Sraffa's system with one degree of freedom indicates that there is no meaning in defining the quantity of capital independent of income distribution , so it means that the marginal product of capital is meaningless, (4) the 'reswitching possibility conflicts with a fundamental postulate of the Neo-classical theory, namely an association between lower rates of profits and higher values of capital per man employed. The difference between Sraffa's system with one degree of freedom and the Walrasian system with zero degree of freedom is not simply concerned with the difference in each its own assumptions about each model. Rather it has a concern with which paradigm they each represents. Sraffa's system contains the aspect of the rule of capitalism but the Walrasian system represents the exchange economy in general. In the Walrasian system, the price of each good is regarded as representing the degree of scarcity and demand plays a critical role in determining the price system. But in contrast with the Walrasian system, the demand has no role in determing the relative price system in Sraffa's system and the price system depends upon the distribution of national income into profits and wages. In the Neo-classical theory, the theory of distribution is simply and extension of the Neo-classical theory and the distribution as such is a matter of concern. But in the classical theory, the distribution theory is considered as a most important key to understanding the historical progress of capitalist economy, and is closely related to other branches of economic theory, such as value and growth. In this context the Neo-classical macro-distribution theory ends with failure. There fave a few attempts to provide the new theories of macro-distribution. They can be represented by M. Kalecki and M. Kaldor. Kalecki attempts to explain the distribution betwee profits and wages in terms of the degree of monoploy. Kaler attempts to apply the Keynesian effective demand theory to the theory of distribution at full employment. Robinson tries to make the Kalecki's theory compatible with Kaldor's theory by introducing "Inflation Barrier". On the other hand. Pasinetti attempts to modify the Kaldor's theory by distinguishing the functional distribution of income into wages and profits from the class distribution of income between capitalists and labors. Pasinetti shows that the rate of profit is determined by the rate of growth and capitalists propensity to same in steady-state growth path. In short, it is expected that we can find the distribution theory of capitalist economy in the Post-Keynesian distribution and growth theory.

In motivation: ① As Hawthorne recognizes, after taking an examination, the importance of the informal organization on the human relationship, and he intends to inspire the will of the labor by a new method. ② As the individual behavior is decided by his strong needs, the administrator must understand what the employee's important needs are. ③ It is necessary that the administrator must enrich one's effort to motivational factor for manifesting employee's working willingness. ④ If human is given a just motivation, he can achieve the goal finely by his effort to face for achiveing the organizational goal. ⑤ To achieve the Organizational goal, there is need for individual to unify to the Organigation. B. In leadership : ① It is Necessary to regard the employee's willness as important, for the employee to achieve the Organizational aim. ② A figure of new manager to achieve the goal is leader who is interested in human and production, and also the interesting degree is owed to both manager and employee. ③ to recognize the higher officials' influence and independence for the forming and maintaining the effective group is become to a good leadership of administrator and superior. ④ The administrators' function is as a leadership of vocational function to meet a need of social situation, it must be displayed when it is faced to a important problem for maintaining the organization.

密貿易의 厚生效果와 最適政策에 관한 硏究

金永春 제주대학교 1990 논문집 Vol.31 No.1

This study attempts to explore the traditional theory of international trade with smuggling which take explicit account of the risk and uncertainty associated with the illegal trade. This paper treated both the Bhagwati-Hansen type of illegal trade through illegal entry points and the Pitt type of illegal trade through legal entry points. The particular model considerd by the simultaneous existence of smuggling, legal trade, and price disparity. Theoretic approach to modelling smuggling places the smuggling literature on a firmer microeconomic foundation. It enables the inclusion of smuggling cost and also allows consideration of the positive and normotive implication of changes in the degree of enforcement. It provided not only an analysis of enforcement, but also of the effects of changes in tariff rates. The main results in this paper may be summarized as follows; First, assuming the probability of being defected smuggling depends positively on the ratio of illegal to lgeal trade an negatively on the real costs of smuggling, the domestic price of the import goods will be lower than the tariff inclusive world price. This result reflects the price disparity in Pitt, Second, although the domestic price ratio is endogenously determined, it depends exclusively on the supply side variables. The same is also true of the read smuggling costs per unit and the ratio of illegal to legal imports, although the absolute quantities of both types of imports do depend on all other parameters in the economy. Third, a more vigorous policy towards the enforcement of laws against smuggling raises real per unit smuggling costs and the domestic price of the importables and lowers the absoluted quantity as well as the share of ilgal imports in total imports. Fourth, the effect of such a policy on the other variables in the economy are ambiguous. Specifically, legal imports and welfare may either rise or fall as the government adopts a tougher policy against illegal trade. Fifth, an increase in the tariff raises the domestic price of the import goods and the ratio of illegal to legal trade. while reducing per unit sumggling cost. Its effect on the absolute quantity of illegal imports is ambiguous.

Project risk management is a management technique of identifying, analyzing and responding latent risk factors in project life cycle. To date, the importance of risk management has been overlooked in the Korean construction industry. The industry's practice of risk management are limited to and concentrated on the construction stage, which cannot propely assess potential risk factors during the project life cycle. Moreover, the research and systematic development efforts on the subject have been very few in the industry. The Purpose of this study is to improve current construction scheduling practices by providing as probabilistic scheduling model that can be utilized during early construction stage.

Counter-Movement Drop Jumping에 있어 落下높이의 影響

裵永相,裵正幸 啓明大學校 生活科學硏究所 1995 科學論集 Vol.21 No.-

The purpose of this study was to examin changes in mechanical power generation at each joint of lower limb during the counter-movement drop jumping at different heights. Eight skilled female dancers were instructed so as to drop jumping on a force platform with their both legs at four different heights (15, 30, 45, 60cm). They were filmed from side with a high speed camera (100fps). The power developed at the ankle, the knee and the hip joint were computed by taking the product of moment of force and joint angular velocity. The mechanical power generated at the knee joint during the counter-movement drop jumping was somewhat larger than that at the ankle and hip joint. The knee extensors and the ankle plantarflexors were the dominant muscle grop during the downward and push-off phase of drop jumping. And the hip extensors were the dominant muscle grop from 10% of the elapsed time to 90% of that. The mechanical work of the hip extensors was observed to increase with dropping height, and the highest mechanical work of hip extensors was found during dropping height of 0.60m. The energy which was produced by a concentric contraction of the knee extensors and the ankle plantarflexors during the push-off phase of the drop jumping was used to extend the ankle and knee and to drive the body upward for the high jump.
