The purpose of this thesis is to analize the investment behavior of the corporations and point out so ne methodobegical problems in the empirical analysis of investment behavior. Generally speaking, we have a tendency hitherto that in the normative theory of investment decisions in financial management we used to dilt with solely the evaluation process of investment proposals or equity value without considering on the investment motives or purposes and the process of plannings. In order band, in the analysis of investment behavior in economics, they used to dilt with mainly the factors of investment demands with the view points of national economic growth or business cycle. But, I think, if we want to understand wholely the investment behavior of the corporations and its investment decisons, we have to analize the investment motives or purposes and the planning process as well as its valuation and the normative theory should be complemented with the empirical study. we have analized some empirical studies on investment behavior of the corporations and point out some methodological problems as follows. 1. The differences between normative theory of investment decisions and the positive or empirical methods of investment behavior 2. The inter-relations of investment beharior of the corporations and acceteration principles 3. Profit motive investment behavior of the corporations 4. The effects of internal finance or residual funds to investment decisions(the analysis of marginal cost of funds) 5. The analysis "acceleration-residual funds hypoihesis" in empirical study on investment beharior by Meyer. J.R. and Kuh. E. 6. The key factors of investment behaviors of the corporations and some methodological problams in empirical study.

The purpose of this thesis is to analize the fuctions of the Cost of capital and capital structure in business enterprise. The problems of the cost of capital in financial uncertainly requires to deal with the optimal financial structure. Recent Contributions in the field of financial management have made the subject broder and more analytical. As E. Solomon indicates, "The advantage of having on optimal financial structure, if such an optimum does exist, is two-fold : it maximeges the value of the comapany and hence the wealth of its ownes : it minimizes the company's cost of capital , whcih in turn increase its ability to find new wealth-creating investment oppertunities" it is said that in analytical process of the cost of capital which is characterizel with "Uncertainly" there must be a new approach which is different from that of so-called neo-classical investment theories. The latter, repreented by Lutz. F and V, is characterized with two propositions; the one is the certainly in forecasting the future, for exapmle, the profit , the other is the perfect capital markets with constant rent. But, as J. Lintner pointed, we could not assume such a "idearized neo-classical markets" in practical management circustances. Accordingly, The formulations of the fuctions of the cost of capital and the optimal finaicial structure differs from that of classical ones. As we knew, there are two ways of approach to analyzing the reasons why the cost of funds differs: in traditional approiach, they insist on that the caures of it due to the imperfect capital markets, effects on taxation. debts etc. The others insist on, as J.Lintner, that the causes due to the aversion toward the risk or uncertainty of investors. which is correct? In this thesis, I have followed the traditional patterns. I have dealt with general and interrelated issues, which affect on capitalization rate under conditions of uncertainity.

經榮意思決定論의 諸 問題 : 意思決定論의 方法論的 考찰

李聖淳 弘益大學校 1971 弘大論叢 Vol.3 No.-

The purpose of this thesis is to analyze the differences between economical analysis approch and behavioral science approach to business decisions and to point out the problems in decision-making. I think there are two basic problems in decision-making. One is how we combine the economic factors and organizational factors in systematic framework of decision-making. The other is to formulate an intergrated method and theory in the area of strategic or non-programmed decisions which needs a new analytic view point. As we know, there are many kinds of decision-making theories because of the difference of methodological stand point: micro-economics or classical theory of the firm, managerial economics, operations research and system analysis, organizational decision-making theory or behavioral decision-making theory and others. But we can classify them into two categories; the first is normative decision theories which has been dealt with the economic side of business behavior exclusively and the second is descriptive or positive decision theory which has pursued the process of decision-making in organizations. It is generally pointed out that in normative decision theory repesented by micro-economics, as R.M. Cyert and others pointed, it is assumed that an organizational goal is given: organizations atempt to maximize profit. They assume that the goal is operational: orgaizations know when they are and when they are not fulfilling that goal and what course of action will satisfy the goal. We believe that this conception of organization goals are foundamentally wrong in some important respects, while the traditional theories of organizational decision making also have a shortage in the view point economic analysis. They used to analyze mainly the process and the general principles of organizational decision making which is adaptable to every kind of public organizations without economic analysis for business purpose. It should not be overlooked, however, that the organizational decision-making theories developed by Chester I. Barnard and H.A. Simon have a classical value on nowadays behavioral science methods of decision-making theory. R.M. Cyert and J.G. March, in their "Behavioral Theory of the Firm" Considered economic purposes of business behavior as well as organizational factors. In methodological stand point, they introduced heuristic problem-solving methods in formulating business model. Which has been developed by H.A. Simon and others in behavioral science, and analyzed the problems of production and price decision. Besides, C.P.Bonini's simulation model which is characterized by a total system is a meaningful study in behavioral science theory of decision-making. The conceptin of simulation model gives us a useful analytic tools both in decision theory and business practice. In current management practice, models are recieving increased attention as aids to decision-making. We have to study what models are, how they are constructed and how they may be used in handling decision problems. In strategic decisions, H.I, Ansoff showed a unique methodogy. At starting point of discussion, he pointed out that "A Beharioral Theory of the Firm" dealt with the area of operational decisions. And he emphasized the importance of strategic decisions and quasi-analytical methods for it which characterized by process oriented, sequential, analytical methods in behavioral sciences. In these methods he wanted to build up a more systematical approach than problem-solving methods. He pointed out that there are two important problems in strategic decision; One is the process of formulating business goals and the other is the rules of strategic decision criterion in which he analyzed synergy effects and competive traits of the business for diversifications. But, Ansoff's stratiegic decision theory, may be critiszed to be lacking in organic structure between the mechanism of organizational decision and the strategic decision model itself. On this point, A.D. Chandler's study has a meaningful conceptions. He investigated the changing strategy and structure of large industrial enterprise in the united states in the standpoint of comparative business history. His discussion is carried further by thesis that structure follows strategy and that the most complex type of structure is the result of concatenation of servreal basic strategies. It is fact that the behavioral science and its methods are widely accepted in management decisions. Especially in the area of strategic decisions, We should not deny its propriety of process oriented, sequential methods and logical positivism in the examination of thesis or models. But it must not overlooked that operations research, systems analysis have become useful methods in management practice. Thus, although we basically accept the behavioral science methods, it is valuable to utilize both of descriptive methods and nomative methods in formulating process of simulation models.

In this paper, we propose a contour-based motion estimation scheme. It is based on the observation that the most significant frame differences occur along moving object edges. It uses discontinuities in image brightness and frame differences to estimate displacements along edges, and avoids the difficult feature-matching problem. The proposed system transmits the contour motion information as overhead information to the receiver. But as only one motion vector per edge neighborhood needs to be transmitted, the overhead is relatively low, while achieving an impressive reduction in the motion compensated prediction error.

The purpose of this the thesis is to anaylize the capital structure and financing in Korean Business and to point out the problems to be considerd for improvement of its inadequacy. We have also studied the trend of changing aspects of capital structure in the other countries-America, Japan, etc.-for the advantage of comparison. In clarifing, it was seen that the capital structure in Korean business is characterized as follows; 1. The reason for the business failure is unbalanced financial structure with over whelming debt. 2. The reason for unbalanced financial structure is due to the failure of self-financing as well as overwhelming debt. 3. Especially the fact that the retained earnings and depreciation charges represent about 20% total financing resources is the one of the important factor for unsound capital structure. In order to facilitate the improvement of the capital structure and financing in Korea Business we can point out some important aspect as follows; 1. Owner's capital should be increased by sales of stock and by retained earnings from 30% at present to a rate 50% of total capital. 2. In order to facilitate the financial market should be enlarged in number of listed securities and the sun of issues. 3. In order to enforce the internal fund resources the accelerating depreciation charges should be applied to greater extent and the rate of taxation of assets ravaluation should be pulled down. The internal fund to the total fund resources should be increased to a 40%. 4. The equipment investment of business and its management should be faciiltated and rationalized for the purpose of the growth of the net worth and retained earning's. 5. Business firms need to have re-organization of financial management by introducing capital structure planning for capital financing and investment.
