I_2 O_2법에 의한 연탄연소 가스중 CO의 정량분석
정기호,李源國 陸軍士官學校 1976 한국군사학논집 Vol.16 No.-
Analytical determination of carbon monxide cantent in the anthracite flue gas was carried out with the method of iodine pentoxide. This flue gas contains about 1 to 2 volume percents of CO, in general, 8 to 9% of CO_2 15% of O_2, 75% of N_2 and an trace(less than 0.04%) of H_2 on dry basis. Temperature(above 100℃) of the iodine pentoxide was not a sensitive factor of carbon monxide oxidation when working with anthracite flue gas.
Insider Trading Regulation and Market Quality: Evidence from American Depositary Receipts
정기호,Hao Zhang 한국증권학회 2010 Asia-Pacific Journal of Financial Studies Vol.39 No.3
We investigate the relation between insider trading law enforcement and stock market quality using a sample of American Depositary Receipts (ADR) over the period from 1998 to 2006. We show that ADR from countries that have enforced insider trading laws have better market liquidity and lower information asymmetry than ADR from countries that have not enforced insider trading laws. In addition, ADR from countries with insider trading law enforcement have greater price efficiency. Our results are robust to different estimation methods and alternative model specifications. We interpret these results as evidence that the enforcement of insider trading laws can effectively deter insider trading and enhance both market liquidity and price efficiency.

Geometric circle and rectangle, often found in the history of Design in Architecture, Town planning and Landscape Architecture, are related in general to symbolistic environment of religious matter or absolute monarchy. A case of this study, an old city Karlsruhe in south German, may be one of the typical examples. Another case of German rural settlement in circular form(Rundling) may be found to stand out of symbolic fashion, if it was studied in its formal development. Thus, the geometric form must be studied out not only terms of aesthetic fashion but also in its matter of life and process of formal development in history.
택리론의 경관론적 고찰 : 복거총론 "산수"를 중심으로
정기호 한국조경학회 1993 韓國造景學會誌 Vol.21 No.3
This paper is a preliminary study to interpret method of landscape evaluation of "Taek-li-ji", and old Book of Settlements in korea, of which concept would be based on 'li' and 'qi':'substance of the earth'(地理) and 'its transform'(生利) as well as 'substance of human being and its transformed human mind'(人心). The 'Landscape' (山水) of Taek-li-ji, character of case study, might be built on practical landscape sources. Concept and theoretical basis of evaluation of Taek-li-ji, mentioned in this paper, and the second intention of Taek-li-ji, which is done in may previous work, can be earned good result, for an interpretation method of rural landscape of Taek-li-ji, and will be proposed continued case studies about real landscapes of the settlements of the 'Landscape' in Taek-li-ji.
전통조경의 조형론적 고찰 -전통 조형물의 형태분석을 중심으로-
정기호,전미경 한국조경학회 1994 韓國造景學會誌 Vol.22 No.1
Until now, Many studies on the traditional landscape architecture were approached to the interpretation of meanings and symbolism in terms of the traditional ideology and the view of nature. The purpose of this study was to research the principle of form included in the space planning by the analysis of the drawing figure. The principes of figure were presented in the space planning as the field of art. In the pavillion and square pond, drawing figure, based on the principle of simple proportions, shall be assured the value of being as a role of functions for planning first of all. Such principles of the functional aspect are in hormony and balance by proportion and thus a visual and structural aesthetic will be abled to refer.
Investment Duration and Corporate Governance
정기호,이영주 한국증권학회 2015 Asia-Pacific Journal of Financial Studies Vol.44 No.1
In this study we analyze the relation between institutional investment duration and corporate governance using a new metric of investment duration that accounts for firm-specific invest- ment durations of each institution. We conjecture that institutional investors that hold a firm’s shares for a longer duration have greater incentives and ability to influence the firm’s governance structure. Consistent with this conjecture, we find that a broadly defined index of corporate governance increases with the duration of institutional ownership. We also show that the relation between investment duration and corporate governance varies across differ- ent types of institutions and across firms with different stock market liquidities.
비수치적 평가 모형에의한 정보기술 프로젝트의 선정 방법
정기호 가야대학교 1999 가야대학교 논문집 Vol.8 No.-
일반적으로 미래기술에 기반한 IT(정보기술)프로젝트들은 미래 상황에 대한 예측과 함께 우선 투자 대상으 선별해야 하는 일련의 작업 과정이다. 그런데 미래기술에 대한 예측뿐만 아니라 미래상황의 프로젝트의 중요성 평가 또한 전문가들의 견해를 따를 수 밖에 없는 상황이다. 이 과정에서 전문가들은 미래상황의 프로젝트에 대한 평가에 계량적인 평가치를 제시하는 것이 매우 부담스런 요소로 인식되며 오히려 언어적으로 모호한 표현을 사용함을 더 선호한다. 이에 본 논문에서는 비수치적 평가로 기술 프로젝트를 선정 할 수 있는 대안적 접근법을 개발하여 제시하고 있다
택배 서비스 네트워크에서 영업소 기반의 전략적 제휴 모형에 대한 연구
정기호,노재정,고창성 대한산업공학회 2008 대한산업공학회 춘계학술대회논문집 Vol.2008 No.5
Recently, the demand for the direct shipment of purchased goods by express couriers has increased as the result of an explosive growth in e-tailing, telemarketing, and TV home-shopping industries. However, since too many express courier companies have been emerging over the last several years, competitiveness for market share is very severe among them. This study suggest a network design model for strategic alliance in order to overcome the circumstances in hot express courier service market. We propose an integer programming model and a solution procedure based on maxmin criterion. To demonstrate practicality and efficiency of the proposed model and solution procedure, a numerical example is derived and tested.
