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.

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

나노소자의 noise 특성을 측정하기 위하여 저온에서 작동이 용이하고 고주파특성을 지닌 cryoamplifier를 제작하였다. 저온에서의 current noise를 측정하기 위해서는 여러 조건이 필요하다. Cryoamplifier는 이런 조건을 만족시켜주기 위해 실험 소자와 같은 조건인 극저온에서 선택적인 영역의 증폭을 수행한다. Multisim과 ExpressPCB를 통해 회로도를 구성하고 HEMT와 각종 filter를 사용하여 cryoamplifier를 제작하였다. 본 연구에서 제작된 cryoamplifier는 5 kHz 이하의 영역과 2 MHz 영역을 filtering하고 77K에서 -6.0 V/V 의 증폭률을 가지도록 설계되었고 실험에 필요한 조건하에서의 테스트결과를 알아본다. To measure noise characteristics of nano devices, we fabricated cryoamplifiers, having high frequency characteristic and good operation ability at low temperature. Cryoamplifer is used to amplify a selected frequency domain at same temperature with test devices. Schematic diagram of cryoamplifier is drawn by Multisim and ExpressPCB. The cryoamplifier is composed by a HEMT and various filters. Homemade cryoamplifiers m this project have two filtering domains and gain, below ∼5 kHz, around 2 MHz and -6.0 V/V respectively. We demonstrate corresponding test results under experimental conditions in detail.

CEO교체의 결정요인에 관한 연구

박준우 한국산업경제학회 2007 산업경제연구 Vol.20 No.4

본 연구는 2000년부터 2005년 사이에 유가증권시장에 등록되어 있는 비금융기업을 대상으로 CEO교체에 따른 경영성과의 변화와 CEO교체에 영향을 미치는 요인을 조사하였다. 주요한 조사결과는 다음과 같다. 첫째, CEO교체 후에 경영성과가 증가하였음을 확인하였다. 둘째, 로지스틱 회귀분석 결과, 경영성과를 나타내는 산업조정ROA는 CEO교체에 통계적으로 유의한 부(-)의 관계를 보여 경영성과가 저조할수록 CEO교체가능성이 높은 것으로 나타났다. 셋째, 광고비/매출액은 CEO교체에 유의한 정(+)의 관계를 보여 광고비지출액이 높을수록 CEO교체가능성이 높은 것으로 나타났다. 넷째, 부채비율과 CEO교체와는 유의한 정(+)의 관계를 보여 부채비율이 높을수록 CEO교체가능성이 높은 것으로 나타났다. This paper investigates the determinants of CEO turnover in Korea. And I examine firm's performance from year -3 to year +3 around CEO turnover. I measure the performance with ROA and industry-adjusted ROA. In this study, 2,490 firms are used as our sample from 2000 to 2005. The results of the study are as follows: First, I find that firm performance increases post-CEO turnover. Second, Industry-adjusted ROA is significantly negative(-) with a turnover dummy. This result means that poorly performing firms' CEOs are more likely to be replaced. Third, Advertising Expenses/Sales is significantly positive(+) with the turnover dummy. It means that poorly performing firms' CEOs increase the advertising expenses to improve their performance. Fourth, Debt ratio is significantly positive(+) with the turnover dummy. It means that the higher debt ratio is more likely to be replaced.

Optical Properties of NiO Thin Films Grown by Using Sputtering Deposition and Studied with Spectroscopic Ellipsometry

박준우,Hosun Lee,Kwan Soo Chung,Kwang Nam Choi,Seoung Ho Baek 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.52 No.6

We deposited nickel-oxide thin films on silicon substrates at room temperature and 500℃ by using a nickel or a nickel-oxide target and DC and RF magnetron sputtering. We annealed the NiO thin films deposited at room temperature. By using spectroscopic eillipsometry, we obtained the refractive indexes, the extinction coefficients, the thicknesses, the band gap energies and the broadenings of the NiO thin films. In order to estimate the dielectric functions of the NiO thin films, we used the parametric optical constant model for the layer analysis. We obtained the band gap energy and the broadening values by using the standard critical point model for the second derivative spectra of the dielectric functions. \textit{We discussed the relations between the optical and the structural properties of NiO thin films as a function of processing parameters such as the thickness, the oxygen flow rate, the growth temperature and the annealing temperature.} We compared the dielectric functions of the NiO thin films with that of the bulk NiO single crystal. The NiO films deposited at 500℃ had not only larger refractive indexes (η) and extinction coefficients (k) but also better crystallinity than those deposited at room temperature. The peak of the refractive index (η) and the threshold of the extinction coefficient (k) became sharp when the films grown at room temperature were annealed. The changes in η and k as functions of the O₂ flow ratio are attributed to both free carrier effects and defects due to excess oxygen. In the case of no oxygen flow, the band gap energy decreased as the annealing temperature increased whereas the band gap energy increased with oxygen flow.

미국 연방저작권법의 저작인격권의 보호-Visual Artists Rights Act of 1990을 중심으로-

박준우 한국저작권위원회 2008 계간 저작권 Vol.21 No.4

The topic of this article is the protection of authors' right in the U.S. After the U.S. joined the Berne Convention for the Protection of Literary and Artistic Works in 1989, which provides the rights of integrity and attribution in article 6bis, it enacted the Visual Artists rights Act of 1990(‘VARA’). However, VARA does not provide rights of attribution and integrity for all authors, but only for visual artists. Therefore, this article clarifies the scope of the protection of VARA by examining its provisions with its legislative history and related cases. Specifically, this article deals with the definition of work of visual art, the test for determining whether plaintiff's work is work of visual art or not, the meaning of singleness, applied art, chart, technical drawing, model, advertising or promotional work, site-specific art, work of recognized stature, and etc. 미국은 베른협약에 가입함을 계기로 저작인격권의 보호를 위하여 ‘Visual Artists Rights Act of 1990’을 제정하여 연방저작권법에 삽입하였다. 그러나 법의 제목에서 알 수 있듯이 이 법은 모든 저작자에게 저작인격권을 부여하는 법이 아니라, 저작인격권의 부여대상을 시각예술저작자로 한정하였다. 또한 보호대상인 ‘시각예술저작물’의 범위도 상당히 제한적으로 정의하여 저작물의 원본만 보호하고, 상업적 저작물은 보호의 대상에서 제외하였다. 따라서 이 논문에서는 VARA의 규정의 내용을 관련 판례 및 입법이유서와 함께 살펴봄으로써 VARA에 대한 보다 정확한 이해를 하도록 하는 것을 그 목적으로 한다.

인터넷에서의 사진저작물의 보호와 부정경쟁

박준우 法務部 商事法務課 2009 선진상사법률연구 Vol.- No.46

이 논문은 타인의 사진작품을 허락 없이 자신의 광고·홍보 기타 영업에 이용한 경우에 저작권 침해가 주장된 사건을 논의의 대상으로 한다. 특히, 이 사건들에서 분쟁발생의 원인과 그 해결을 위한 법적 수단의 괴리를 지적하고, 이를 보완하기 위한 법리로 부정경쟁방지를 위한 불법행위법리의 사용을 논의한다. 이를 위해 우선 인터넷에서의 사진저작권 침해 관련 판례의 내용을 살펴보고, 대부분의 사건들에서 원고가 원하는 것은 저작권의 침해방지가 아닌 경쟁에 있어서의 무임승차의 방지이므로 부정경쟁의 방지를 위한 불법행위의 필요성과 인정요건, 그리고 그 한계를 논의하는 순서로 논문을 전개한다. 우리나라의 부정경쟁방지법이 한정적 열거방식을 취하고 있는 시점에서 민법 제750조를 근거로 한 불법행위법리의 이용은 저작권법을 보완하는 매우 유용한 수단이 될 수 있다. 이 논의는 결국 배타적 권리에 의해 보호되지 아니하는 상업적 가치가 있는 정보를 경쟁관계에서 이용함에 있어서 위법성이 있는 경우와 없는 경우를 구별할 수 있는 기준의 마련에 관한 논의가 될 수밖에 없다. 결국 경쟁관계에서의 위법성의 판단은 침해행위로 인해 얻는 이익과 침해된 이익의 비교형량을 통하여 상대적으로 판단할 수 밖에 없고 판결을 통한 영업이익침해의 유형화가 필요하다고 본다. This article deals with copyright cases, in which defendant uses plaintiff's photographs for advertisement of her website without consent. This article discusses on the tort doctrines to fill the gap between plaintiffs desire to prevent defendant from using her photographs for advertising purposes in the context of competition and the copyright tool to resolve the dispute. This article first introduces the facts and court decisions of related cases, and argues that though plaintiff claims defendant's copyright infringement, what plaintiff wants is not the return of her investment in creating photographs, but the prevention of competitors' free-riding. Therefore, this article argues that unfair competition approach is more appropriate than copyright approach in this context. However, the Korea Unfair Competition Prevention Act does not have a general provision prohibiting unfair competition, but provides an exhaustive list of unfair competition. Thus, development of tort doctrines to prevent unfair competition is necessary and at the core of the future discussion should be the test for the distinction of illegal competition from lawful one.

공정이용법리의 기원과 의의 - 퍼블릭도메인의 확보를 위한 공정이용규정의 제안 -

박준우 전남대학교 법학연구소 2009 법학논총 Vol.29 No.2

The purpose of this article is to find out the theoretical background that explains why copyright shows more exclusivity than that of patent or trademark rights. Among various subjects in copyright area, this article focuses on the origin and historical developments of the fair use doctrine in the English and U.S. jurisdiction. For this purpose, Part II of this article introduces the facts and holding of the U.S. case that, for the first time, mentioned the fair use factors, that is, Folsom v. Marsh in 1841. Part III examines the historical developments of the two polar legal theories that justifies copyright: natural law theory and utilitarian theory. Based on the discussion in Part III, Part IV evaluates ‘fair use doctrine’ in Folsom as expanding the scope of copyright, rather than limiting it. Folsom ignored then established utilitarian approach of the Supreme Court, and became the cornerstone of natural law approach of the copyright jurisdiction. Part V evaluates article 107 of the 1976 Copyright Act from the utilitarian perspective. Finally, this article proposes a fair use provision to secure public domain

대학 청년 졸업자의 취업 성공 결정요인 분석 : 전국 5대 권역을 중심으로

박준우,여찬구 조선대학교 지식경영연구원 2022 기업과 혁신연구 Vol.45 No.4

본 논문은 전국을 5대 소재권으로 구분하여 2019년도 대학 청년 졸업자의 취업성공에 영향을 미치는 결정요인을 확인하였다. 그 결과 지역마다 상이한 점이 일부 발생하였지만, 개인적 특성인 나이, 부모의 소득은 취업성공에 정(+)의 영향을 미치는 것으로 나타났고, 부모의 자산은 유의하지만 취업성공에 부(-)의 영향이 나타나는 것으로 분석되었다. 전공의 경우 사회․공학․예체능 계열은 전공이 취업성공에 정(+)의 영향을 미치는 것으로 나타났지만, 교육계열 전공은 취업성공에 부(-)의 영향을 미치는 것으로 나타났다. 학교 유형에서 교육대는 취업성공에 정(+)의 영향을 미쳤으나 4년제 대학 및 국공립 대학은 취업성공에 부(-)의 영향을 미치는 것으로 분석되었다. 그 밖에 취업 준비 행동적 특성으로 직업 능력 향상 교육과 관련 전공 자격증 취득은 취업성공에 정(+)의 영향을 미치는 것으로 분석되었다. 반면 일반 자격증 취득은 취업성공에 부(-)의 영향을 미치는 것으로 분석되었다. 이는 취업 직종과 목표에 상관없이 단순히 ‘스펙 쌓기식’ 취업 준비는 취업에 부정적 영향을 준다는 것을 시사한다. 그 외 취업관련 활동 경험으로 SSAT, 공모전, 대외활동은 취업성공에 정(+)의 영향을, NCS, 외모관리는 부(-)의 영향을 미치는 것으로 분석되었다.
