      • 投資行動의 實證的分析方法에 관한 硏究

        李聖淳 弘益大學校 1976 弘大論叢 Vol.8 No.-

        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.

      • 노발리스의 서정시에 나타난 종교성

        이성순 한국헤세학회 2003 헤세연구 Vol.9 No.-

        In der vorliegenden Studie will ich die Religiositat in den Gedichten von Novalis untersuchen. Die Grundlage der Poetologie von Novalis basiert auf zwei Erlebnissen: dem Sophienerlebnis und den philoso- phischen Studien. Er erlebte den Tod seiner jungen Braut Sophie im Jahre 1797 und mußte ihren Tod als seinen eignen Tod geistlich erleiden und die erneute Einsamkeit und Verlorenheit uberwinden. Der Tod ist fur ihn kein realistischer Tod in seiner Dichtung, sondern neues Leben, Dasein mit Sophie verwoben. Dabei offenbart Sophie sich als die Bilder Christus und Marias und dadurch konnte Novalis den Tod im Glauben an die ewige, unwandelbare Liebe uberwinden. Novalis hat 『Hymnen an die Nacht』, Geistliche Lieder mit der Ursache dieses religiosen Erlebnis geschrieben. Darum sollen diese Werke nicht nur als poetischen Erlebnisdichtung betrachtet werden, sondern auch als poetische Summe inneren Entwicklung, die der Dichter bis zum Romantikertreffen im Jenakreis durchgemacht hat. Die 『Hymnen an die Nacht』 sind das Dokument eines freien Christen, dessen Schrift den Schreiber selbst verwandelte. Sie sind in Form einer Dichtung, was fruhere Maler in Bildern eines “Kreuzwegs” gemalt und in die Kathedralen des Mittelalters gestellt hatten. Die vierte Hymne erscheint ja ganz deutlich bis auf die einzelnen Wortlaute hin als eine “Kreuztragung”, als eine Wallfahrt zum heiligen Grab. Das Schlußgedicht der vierten Hymne empfindet den Tod auf Golgatha in individuellster Wortform. Die Bilder der funften Hymne empfinden Grablegung und Auferstehung nach, und die sechste Hymne schildert ihrem Charakter nach eine Himmelfahrtsszene, denn das Grundmotiv ist nicht “Sehnsucht nach dem Tode”, sondern Ruckkehr zum Vater. 『Geistliche Lieder』 ist eine Lobeshymne fur Maria und Christus. Diese Lieder rufen in ihren siebenstufigen Aufbau gleichsam die Stunden eines individuellen Erweckungstages aus. Die Lieder singen von den Festen eines gemeinschaftlichen Jahres. Novalis nannte die Gedichte Christliche Lieder und wollte ihnen fur die Veroffentlichung im Athenaeum, die nie zustande kam, den Titel Probe eines neuen geistlichen Gesangbuches geben. Friedrich Schlegel und Ludwig Tieck nahmen nun aus beiden Uberschriften ein Wort heraus und veroffentlichten die Dichtung nach dem Tode in der Ausgabe seiner Schriften unter dem Namen 『Geistliche Lieder』. In Novalis lebte Ankunftsstimmung eines Zeitalters, das sich mit ihm in Augenblicken des Sehertums zur Gewißheit der Christus-Gegenwart steigerte. Erst allmahlich hat er in unserem Jahrhundert Heimstatt gefunden. Als ein Kommender wird er in das kunftige Jahrtausend eingehen. Seine Wirkung wachst in die Weite der Welt.

      • 국제투자신탁의 운용성과평가에 관한 연구 : 외국인전용수익증권과 Country Fund 를 중심으로 With Special Emphasis on On-Shore Trust and Country Fund

        李聖淳,金仁培 홍익대학교 경영연구소 1999 경영연구 Vol.24 No.-

        The purpose of this study is to analyze the efficiency of information and the difference of their management ability, to investigate the characteristics of the investment behavior of foreign investors and domestic investors, and to analyze the efficiency of securities market, also to analyze the relationship of the net asset value fluctuation of country fund and the trading price fluctuation of country fund listed on the stock exchange. The methodology of empirical study is as follows. The subject of analysis period is established for ten years, that is divided two times rising periods ad two times declining periods. The object of analysis fund is seven on-shore-trusts and three country funds, which are established before 1987. As the object of analysis period is from the beginning of 1987 to the end of 1996, to compare KOSPIs rate of return with funds rate of return, funds are established before 1987 are selected. To evaluate performance of funds this study is used criteria three traditional model, namely Sharpe, Treynor, and Jensen Measures. Also market excess rate of return, risk and determination coefficient are used. Treynor-Mazuys quadratic term regression model is used with Jensen model to evaluate fund managers management ability. For relationship analysis the fluctuation of net asset value and the fluctuation of market price on Korea Fund groups average difference analysis(t - test), methods of correlation analysis, and Kendall, Spearman correlation analysis and factor analysis are used. The following is the result of empirical analysis. First, it could not be confirmed that the management rate of return of international investment trust is higher than the market average management rate of return market. It means that it is difficult to judge that markets are inefficient. Second, through entire period, the rate of return of international investment trust in our country is similar to markets rate of return in terms of stability. And through the entire period, the international investment trust of our country has done a defensive asset management, and it shows that when market rising, defensive management has been done and when declining, aggressive asset management has been done. Third, under any market situations, the rate of return fluctuation of net asset value of international investment trust can be explained in general by the market rate of return. Fourth, through the entire period of international investment trust, Sharp index shows the negative value and Treynor index and Jensens alpha shows the positive value. During the rising period, all show positive value, but during the declining period, both Sharp index and Treynor index show negative value, and Jensens alpha shows positive. Fifth, through the entire period of analysis object, all funds θ_p has negative value in market timing ability and so it is appeared that fund manager of international investment trust don't have market timing ability or are in shortage of it. And through the entire period of analysis object, it is appeared that the total average of market ability by Jensen model decomposition has negative value and so the fund managers of international investment trust don't have market timing ability or are in shortage of it. Consequently, it has not been discovered that the fund managers of international investment trust have market timing ability. Sixth, through the entire period of analysis object, we have not been able to discover the proof that though the most fund in stock selectivity ability by Treynor - Mazuy model show positive α, but it is not significant statistically and the fund managers of international investment trust have the stock selectivity. And through the entire period of analysis object, as a result of the regression analysis by model, Jensen's average α is showing positive average. This statistical volume is turned to be having no significance and so it has been appeared that they don',t have any stock selectivity or are in shortage of it. This means that there is no proof saying that our markets are inefficient. Seventh, though non-significance by the phenomena appeared, in view of size, the management ability of foreign fund managers who manage country fund shows a little higher than the domestic fund managers who manage on-shore-trust in excess rate of return, risk, Sharpe index and Treynor index. But it can be confirmed that there is no difference between the management ability of foreign fund managers who manage country fund and the management ability of domestic fund managers who manage on-shore-trust by the result of t - test between two groups. Eighth, as a result of analysis, the fluctuation of the net asset value of country fund affects the trading price fluctuation of country fund listed on the stock exchange, On the other hand, the limit point of this study can be summarized as follow as a whole. The period of analysis being overextended, the analized as fund reached the number of 10, the generalization of the result has difficult limit. And it may have chances that the result of analysis might face small sample bias.

      • 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.

      • 이동 물체의 에지를 이용한 변위 추정

        이성순,김형종,한승조 조선대학교 동력자원연구소 1997 動力資源硏究所誌 Vol.19 No.1

        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.
