This study was conducted to detect the allelopathic effect of water and ethanol extracts from 4 plant species (Lactuca sativa L., Ambrosia elatior L., Oenothenra odorata Jasp., Ginkgo biloba L.) on germination and growth of lettuce seeds. A little bit higher inhibitory effect was obtained in ethanol extracts rather than water extracts. Allelopathic effects varied in the source of extracts and concentrations of 4 plant species and the highest allelopathic effect appeared in 10% solution, regardless of plant species.

복부 X선 촬영에 있어서 피폭 선량경감에 관한 연구

承健男 대구보건대학 1984 대구보건대학 論文集 Vol.8 No.-

복부 X-선 촬영시에 환자에 대한 피폭선량을 경감시키기 위하여 감도별 증감지와 관전압을 이용하여 실험하였으며 그 결과 다음과 같은 결론을 얻었다. 1. 증감지의 감도는 관전압이 증가됨에 따라 증가되었으며 증감지별로서는 special speed증감지가 우수하였고 special speed 증감지를 사용함으로서 medium speed 증감지 비해서 7.8배로 감도를 증가시킬 수 있었다. 2. 선예도는 관전압의 상승과 증감지의 감도에 반비례하였다. medium speed 증감지를 사용했을 때 감도와 선예도를 각각 100으로 기준을 잡으면 관전압 100 kv에서 special speed 증감지는 257로 증가되는데 비해서 선예도는 67.2로 나타났다. 3. 피폭선량을 표면선량으로 비교할 때에 비해서 100 kv에서 special speed증감지에서는 많은 피폭선량 감소를 보였다. 표면선량이 가장 적은 것은 관전압 100 kv에서 special speed 증감지를 사용할 경우로서 64 mR이고 다음은 역시 special speed증감지를 사용하여 120 kv에서 74 mR으로 나타났으며 medium speed 증감지와 80 kv에서는 663 mR로서 많은 피폭선량을 보여주고 있다. 그러므로 복부 X-선 촬영에서 가급적 고감도의 증감지를 사용하고 관전압은 100 kv이상으로 한다면 환자의 피폭선량을 경감시킬 수 있다는 실험결과를 얻었다. An experimental study for the reduction of exposure dose rate in abdominal vital organ roentgenography in plain film exposure with different screen was implemented and results were as follows : 1. With increasing volts in electricity the sensitivity of intensifying screen was increased accordingly therefore special high speed intensifying screen was the best quality for the reduction of dose rate in comparison of 80 kvp medium speed to 120kvp high speed which is more increased sensitivity in 7.8 times. 2. Sharpness was inversely proportional to the increased volts and sensitivity response to the intensifying screens. As of comparison in 100 of medium speed screens high speed screens become 69.2. 3. Exposed skin doses were resulted in 1/10 of reduction in skin dose in special speed high intensifying screens 100 kvp or more compare to the 8okvp medium speed one. From these results reducing skin dose rate in abdominal exposure of plain Roentgenogram should be utilized more in 100 kvp or more of high voltage and super sensitive hi& speed screens of intensification of exposure dose in abdomen.

장애인고용정책의 문화이론적 분석

이곤수 한국장애인고용촉진공단 고용개발원 2006 장애와 고용 Vol.16 No.2

이 연구는 장애인고용정책의 설명을 위해 Douglas와 Wildavsky의 문화이론을 도입하여 문화적 분석을 시도한 것이다. 이는 사회적 가치와 신념 및 구성원들 간의 사회적 관계를 혼합하여 문화에 관한 체계적 유형론으로 정립된 문화이론은 장애인차별 및 고용문제와 같은 문화적 민감성이 높은 정책이슈들에 내재하는 가치 갈등의 문제를 설명하는데 유용하기 때문이다. 연구는 장애인고용정책의 문화론적 접근의 필요성과 가능성을 검토하고, 운명주의· 계층주의· 평등주의· 개인주의의 4가지 삶의 양식으로 구분되는 문화유형에 따라 장애인고용의 정책논리와 양상을 살펴보고, 한국의 장애인 고용과 정책에 대한 문화론적 분석으로 이루어졌다. 분석결과를 통해 장애인고용문제는 운명주의와 계층주의적인 삶의 양식, 형식적 평등주의와 실질적 계층주의의 정책, 그리고 개인주의적 삶의 유형이 혼재하는 평등주의 지향의 장애인운동 속에서 가치갈등을 내포하고 있음을 보여주었다. 이를 토대로 장애인차별을 해소하고 평등과 사회통합을 실현하는 바람직한 장애인고용저책을 위해서는 직업재활과 개인적 서비스 공급에 한정되는 계층주의를 극복하고 적극적 고용정책을 처방하는 평등주의적 삶의 양식의 실질적 확립을 위한 문화변용자로서 역할 수행이 필요함을 시사하였다. This study aims to explain the process of the employment policy for people wlth disabilities by applying cultural theory developed by Douglas and Wildavsky. Cultural theory proposes four ways of Iife as culture types wlth the two dimensions of group and grld. Those four ways of Iife are hierarchy, fatalism, egalitarianism, and indivldualism. Using thls analysing lens of cultural theory, in this article, I attempt to provide cultural interpretations on the disable's way of Iife, a way of Iife Iied at the basis of the employment policy for the disabled, and the way of Iife intended by the emerging disability movement. This research shows that issues of the disabled employment take a value conflict situatlon which it is mixed characteristics of fatalistic or hierarchic way of Iife in labor market and features of hierarchic or egalitarian way of Iife in area of pubic policy for people with disabilities. The paper concludes with a proposal for a cultural view of publc policy as a catalytic agent for acculturation and asserts that the civic movement and public policies for people with disabilities should be focused in the intervention toward the egalitarian way of Iife.

외국의 지적재산권 보호가 한국의 FDI에 미치는 영향에 관한 연구 : 국가특성과 산업특성을 중심으로

박건영 한국관세학회 2007 관세학회지 Vol.8 No.1

The main purpose of this research is to empirically examine the effects of foreign intellectual property rights(IPRs) protection on the FDI volume of Korea. In the empirical analysis, I have applied the gravity model to the FDI data of Korea from 2001 to 2003, divided by host countries and industries. As the results, I have found that foreign IPRs protection has negative effects on Korea FDI volume, which means that the high level of foreign IPRs protection should not result in increasing Korea FDI volume on average. The effects of IPRs, however, differ with trading partners and industries. Specially, there are the negative effects of IPRs in the FDI of manufacturing industries to developing countries. From these results, I have concluded that the effects of foreign IPRs protection differ with the characteristics of host countries and industries and these differences must be considered in policy related with foreign IPRs.

不動産의 正常價格과 最有效使用에 관한 硏究

李建世 건국대학교 1987 論文集 Vol.24 No.1

Development and progress in real estate appraising depends heavily on the knowledge of economics which accumulates throughout history Value theory and practice as taught by leading appraisal societies today are largely a synthesis of the important ideas and economic concepts developed by leader of the Classical, Austrian, Historical, Neoclassical and Modern schools of Value Theory. Market value may rightfully be designated as the heart of all real Estate Value. Market Value is the price which a property will bring in a competitive market under all conditions requisite to a fair sale, which would result from negotiations between a buyer and a seller, each acting prudently, with knowledge and without undue stimulus. But, some appraisers, real estate experts, and economists maintain that technically it is impossible to estimate the market value of real estate according to the assumptions contained in the standard definitions as given above. This view is advanced by Dr. Richard U. Ratcliff, who objects to the legal definition of market value since it refers to hypothetical buyers and sellers who bargain under hypothetical market conditions. This interpretation views the value estimate not as an interpretation of what would happen under ideal condition, but what will happen under actual circumstances. Fundamental to the concept of market value is the Principle of Highest and Best Use. Highest and Best Use is logically defined as "that possible and legal use or employment which will preserve the utility of the land and yield a net income flow that forms, when capitalized at the proper market rate of interests, the highest present value of the land." But, The Principle of Highest and Best Use Contains similar problems in its unrealistic assumptions. The following are the principal objections raised to The Highest and Best Use concepts by those who advocate a Most Probable Use. - There can be more than one highest and best use for a property. - The highest income does not necessarily represent the highest and best development of the property, for two reasons ① The use may involve depletion of the property ② The income may entail a high risk factor, resulting in lower value. In the context of most probable sales price another appropriate term to reflect highest and best use would be most probable use. In the context of investment value an alternative term would be most profitable use.
