인플레 豫測에 있어서 媒介指標의 役割

朴俊佑 상명대학교 논문집 1984 상명대학교논문집 Vol.14 No.-

In many economic theories expectations about the future values of economic variables play an important causal role(s), since economic outcomes are influenced by the perceptions of various economic agents as to future economic state. Unfortunately the mechanism by which economic agents form their expectations, in general, is not known. This unobservable feature of the expectation mechanism has led many attempts to find a good proxy or model for the expectation mechanism. The traditional approach to this matter has been the use of current values rather than expected values of economic variables, based on the very unrealistic and simple hypothesis of convention that the current state of affairs continue indefinitely. Dissatisfaction with this naive view has led two opposing approaches. The purely extrapolative expectation hypothesis seeks the rationality of the expectation mechanism in the learning process of the public through experience with past inflation rates, concluding that the monetary authority or government can conduct effective countercyclical policies, since inflationary expectation is solely a function of the past inflation series and so changes in economic policy variables play no effective role in the inflationary expectation by the public. The rational expectation hypothesis, on the other hand, looks for rationality from various other pertinent aspects apart from the learning process involving past inflation experience and insist that changes in economic policies have a very effective role in influencing the inflationary expectations. This, in effect, precludes the possibility that the monetary authority or government could control the course of inflation. The purely extrapolative expectation hypothesis can be perceived to be a naive approach in view of the increasing array of other information which is made available, the accessibility of modem computer devices, and the role of the professional economic analysts. Achieving the optimal rationality of the expectation by the public, however, is still hampered by the constraints of the real time and information and computational costs of the expectation behaviour and also by what H. Simon refers to as the relativeness of the memorial power of human mind. In this paper it has been attempted to reformulate the propositions of the rational expectation hypothesis in order that it can embody these aspects of the expectation mechanism of the economic agents and to conduct a hypothesis test. The result offers an empirical support for the hypothesis that the information contained in the intermediate indicators is intensively used in addition to the past inflation series through the sequential exploitation behavior of the public and so the changes in economic policy variables most-likely have indirect effects on the intermediate inflationary indicators. And it also provides an ecletic view that the countercyclical policies formulated according to a formulated rule or system do have some control over the course of inflation though their effects are not as potent as suggested by the purely extrapolative expectation hypothesists.

E-beam Lithography를 이용한 3차원 Air-bridge 구조의 제작기법

박준우,정희준 한양대학교 이학기술연구소 2008 이학기술논문지 Vol.12 No.-

본 실험에서는 E-Beam lithography 기술을 이용해서 3차원 구조물인air-bridge를 제작해 보았다. wafer에 서로 다른 민감도를 지닌 PMMA를 다층구조로 쌓아올린 후 다양한 dose 값의 노광을 통해 bridge 형태의 구조를 제작하였다. 또한 설계된 디자인으로 patterning후에 한번의 Au, Cr 증착을 통해 bridge를 완성하였다. 본 연구에서 사용된 제작 방법을 통해 기존의 방법보다 빠른 진행과정으로 보다 신뢰성 있는 air-bridge를 완성하였으며 다양한 형태의 복잡한 구조물에 응용 가능함을 알게 되었다. In this study the three-dimensional air-bridge structures are fabricated using Electron Beam Lithography. A bridge structure is formed by projecting electrons to PMMA multi-layers with varying dose values. Each PMMA layer is differently reacted to incident electrons. The air-bridge structures are fabricated with patterning and evaporating gold (Au) and chrome (Cr). Our fabrication method can be applied to various complex nano-scale structures. Likewise we are known that our process is faster than the previous method and is more reliable for fabricating air-bridge structures.

Comparison of Binocular Function and Surgical Outcomes of Tenacious Proximal Fusion and High Accommodative Convergence/Accommodation Ratio Types of Intermittent Exotropia

박준우,이수정 대한안과학회 2018 Korean Journal of Ophthalmology Vol.32 No.6

Purpose: To compare the characteristics and surgical outcomes in patients with tenacious proximal fusion (TPF) and high accommodative convergence/accommodation ratio (AC/A) types of intermittent exotropia. Methods: This study retrospectively enrolled 40 patients with intermittent exotropia, 23 with TPF and 17 with high AC/A. Binocular function was evaluated by Worth’s 4-dot test. Patients underwent lateral rectus recession, and surgical outcomes were compared. Surgical success was defined as less than ±10 prism diopters (PD) at 12 months postoperatively. Results: The proportion of diplopia at near, evaluated by Worth’s 4-dot test, was significantly higher in patients with high AC/A than in those with TPF (35.3% vs. 4.3%, p = 0.029). The mean preoperative angles of deviation in TPF and high AC/A types were 28.3 ± 4.4 and 28.8 ± 4.5 PD at distances, and 14.7 ± 4.2 and 15.1 ± 4.1 PD at near. Twelve months after surgery, the mean angles of deviation in TPF and high AC/A types were 2.9 ± 9.8 and 1.2 ± 9.6 PD, respectively, at distance and 1.7 ± 7.7 and -1.3 ± 11.3 PD at near. The surgical success rates were similar in the TPF and high AC/A types (74.0% vs. 64.7%). Five (21.7%) patients with TPF and 2 (11.8%) with high AC/A type experienced recurrence, with consecutive esotropia occurring in 1 (4.3%) patient with TPF and 4 (23.5%) patients with high AC/A. Conclusions: The proportion of diplopia at near was higher in patients with high AC/A type than in those with TPF intermittent exotropia. However, the surgical success rates were not significantly different between the types.

외국인투자자가 재무성과와 기업가치에 미치는 영향

박준우 한국기업경영학회 2011 기업경영연구 Vol.18 No.2

Since Korean Capital Market has been opened to foreign investors, they have had a big impact on Korean Stock Market. Therefore, researchers has been interested in this subject. Many scholars make affirmative evaluation with the their roles. This study attempts to examine how foreign investors might affect the performance and value of Korean companies. Followings are more specific goals of this study. (1) to investigate how the holding share of foreign might affect the financial performance(measured by OROA, operating return on asset). (2) to inspect whether the holding share of foreign might affect firm’s value(measured by Tobin’s q). (3) Foreign investors are divided into the two groups that have share over 5% or below 5%, and then execute above (1) and (2). As the results of these analysis, the author find that foreign investors have a positive(+) effect in financial performance and firm’s value. This finding means that because they carry out the role as the monitor of firms, might affect the financial performance and firm value. According to the analysis by holding share, the author find that two groups all have a positive(+) effect in financial performance and firm value. However, in firm value, the group that hold share over 5% has a positive(+) result,and the group that has share below 5% has negative(-) effect. From the empirical evidence it might be inferred that the foreign investors would affect positively helping to make companies more profitable and valuable. 국내 자본시장이 완전 개방된 이후 외국인투자자의 역할은 매우 중요하다. 외국인투자자의 역할에 대한 논란에 대해 최근 국내외의 연구에서 대체적으로 긍정적인 평가를 내리고 있으나, 다양한 접근에서의 연구가 요구되는 시점에 있다. 본 연구는 외국인투자자의 지분소유가 국내기업의 재무성과 및 기업가치에 어떠한 영향을 미치는지를 동시에 살펴보았다. 분석결과, 대체적으로 외국인투자자는 국내기업의 재무성과와 기업가치에 유의한 양(+)의 영향을 미치는 것으로 나타났다. 이는 외국인투자자가 국내기업들에 대해기업경영의 감시자 역할을 수행하여 기업의 재무성과 및 기업가치의 증대를 가져오는 것으로 해석할 수 있다. 외국인소유지분별 분석결과를 살펴보면, 외국인소유지분율 5% 이상인 기업과 5% 미만인 기업 모두 재무성과에 양(+)의 영향을 미치는 것으로 나타났다. 기업가치에 있어서, 외국인 소유지분율이 5% 미만인 경우에는 기업가치에 음(-)의 영향을 미치는 것으로 나타났으나, 외국인 소유지분율 5% 이상인 기업은 기업가치에 양(+)의 영향을 미치는 것으로 나타났다. 결론적으로, 외국인투자자는 국내기업의 경영 및 기업가치에 대체적으로 긍정적인 역할을 수행하는 것으로 평가할 수 있으며, 이들의 역할에 대해서는 외국인투자자의 유형을 좀 더 다양하게 분류하여 연구할 필요가 있다고 판단되어진다

SRI지수 편입기업과 주가행태

박준우,곽세영 韓國生産性學會 2012 生産性論集 Vol.26 No.4

This study is about to empirically investigate the stock prices and volumes effects associated with addition to the SRI index. Using the 89 listed firms in the stock market from 2009 to 2011, the author analyze the stock prices and volumes by an event study. The results are summarized as follows. Firstly, it has come out that the informations on addition to the SRI index can positively affect in the market, but the price rollback has been founded at the next day after the change-day. This results may support the price pressure hypothesis. Secondly, it was observed that the excess volumes of the firms incorporated into the index were the high level in a short term, but these were not lasted on in a long term. Thirdly, the change rates of volume were higher than those of the disclosure days, but not in a long term. Consequently, the author are able to embrace the price pressure hypothesis, and furthermore the liquidity hypothesis can be also adopted because the stock prices rose up and the volumes increased for a short period of time. However the stock prices were not rising up for a long time so that it can be not adopt the downward-sloping demand curve hypothesis and the information hypothesis.
