This study attempts to identify the difference of consumer’s preference of rewards divided by image of country of origin. And to investigate the moderating role of consumer’s effort in country of origin effect. In the experiment, participants showed the highest preference when rewards which has positive image related to country of origin were offered, followed by rewards of neutral image, and ones of negative image. In addition, the difference of preference between rewards of positive image and ones of negative image was strongly influenced by a lower degree of consumer’s effort compared to a higher degree of it. Lastly, after controlling rewards of neutral image, the difference of preference between this and rewards of positive image was strongly influenced by a degree of consumer’s effort. But the difference of preference between that and rewards of negative image was not influenced by it. The results indicate that extrinsic cue, country of origin, which is the new concept on research of rewards program is the important factor for drawing consumer’s responses effective for company.

Temperature is one of the most important variables in thermal-hydraulic system. Many methods like, thermo couple, thermistor, semi-conduct sensor and so on have been divised for the temperature measurement. Recently optical method has attracted much interest due to its insensibility to electromagnetic environment. When liquid crystal film is attached to an object, its color changes sensitively as according to the temperature of the object. If a specific light is flashed on the film, the amount of light reflection depends on the color of the film. The purpose of this study is to develop an optical temperature measuring system using liquid crystal film.

Fin-tube type(Fin-type) heat exchanger has been tested in order to replace the heat exchanger of parallel flow type(P.F-type) which is now widly used in automobile air conditioning system. The following conclusions are drawn by the comparison of the characteristics of the heat exchangers. Evaporator and condenser capacities and COP(Coefficience of performance) were varied as with the compressor speed, outdoor air temperature and air flow rate changed, which much influenced on the characteristics of the air conditioning system. Evaporator and condenser capacities were increased with increasing compressor speed and outdoor air temperature. Evaporator and condenser pressures of Fin- type were decreased by 7% and 5% respectively compared with those of P.F-type. The COP of Fin-type was decreased with increasing outdoor air temperature and compressor speed. The COP of P.F-type was decreased by 14% compared with that of Fin-type.

The authors describe two cases of unusual intracranial metastatic adenoid cystic carcinomas. A 42-year-old woman had a right pariental epidural metastatic mass. presumed hematogenous. spread from a primary tumor in the parotid gland. In second case, a 32-year-old man had a intracranial metastatic adenoid cystic carcinoma mimicking calcified psammomatous meningioma on CT scans. We present these unusual cases with a review of relevant literature and a discussion of possible pathogenesis.

This paper discusses a real time multi-tasking system model and a development environment for an elevator control system. Recently, as the elevator systems become large-scaled and operate with high speed, there are lots of software tasks to be processed with time constraints. Thus, the control systems are designed with distributed control structure and characteristics of typical real time systems. For structural design of such real time system, we introduce a multi-tasking model based on a real time operating system model and an software development environment based on virtual prototyping which simulates real system operation in the cross development environment. The developed system model and the development environment are successfully applied to development of a new elevator system with distributed control structure and its system reliability can be verified through numerous field tests.

In this study, we have measured scintillating light generated in a fiber-optic dosimeter by high energy photon and electron beams using a charge-coupled device. The intensity of Cerenkov lights are also measured and characterized as functions of incident angles and energies of the high energy beams from a clinical linear accelerator. To minimize or remove Cerenkov light, a simple subtraction method using a background optical fiber and wavelength discrimination method using optical filters are investigated. Also, the intensities of Cerenkov light induced by high energy photon and electron beams are compared.

The survey was carried out to investigated the contamination of streams by the acid mine drainage originates from abandoned coal mines and coal refuse piles. The physico-chemical characteristics such as pH, sulfate and elements concentrations of waters and sediments in streams were analyzed, and the microbial activities in the sediments were evaluated by measuring dehydrogenase activities. In sites contaminated by the acid mine dranage, the pH of waters adn sediments declined to acid from neutral due to the accumulation of sulfate. Dehyfrogenase activities ranged from 12 to 170 ㎍-TPF·g-dry soil-¹·24h-¹in the contaminated sites, whereas teh uncontaminated sites had activities of 1,176-4,259 ㎍-TPF·g-dry soil-¹·24h-¹. Dehydrogenase activities were significantly affected by low pH of sediments, indicating that high strength of sulfate inhibited microbial activities. The concentrations of heavy matals such as Pb and Fe in contaminated sediment (37-46 ppm Pb; 46,000 ppm Fe) were much higher than those in the uncontamnated sediments. concentration of Al in the contaminated water acidfied by the abandoned coal drainage was in range of 11 to 42 ppm. compared with those in the uncontaminated sediments, the concentrations of Mn, Mg and Ca in contaminated sediments were low because of the leaching of them from soil to water by acidfied stream water.

강원도 태백시 황지의 폐탄광과 폐광석 더미에서 유출되는 산성 광산배수의 유입으로 인한 주변 하천의 오염 실태에 대하여 조사하였다. 하천의 오염도를 알기 위해 하천수와 하상퇴적물의 pH, 황산염이온 농도 및 무기원소 농도를 측정하였으며 하상퇴적물에 서식하는 미생물의 활성을 탈수소효소활성(DHA)으로 측정하였다. 폐탄광과 폐광석 더미의 배수가 직접 유입되는 지천에서는 산성 배수의 유입으로 인해 하천수와 하상퇴적물의 pH 가 중성에서 산성으로 감소하였다. 또한 산성 광산배수가 유입되지 않은 청정지역에서 하상퇴적물의 DHA는 1,176∼4,259g-TPF·g-dry soil()·24h()이었으나 유입되는 지천은 12∼170g-TPF·g-dry soil()·24h()로 매우 낮았다. 청정지역과 비교하여 오염된 지역의 하상퇴적물 중에서 Pb와 Fe의 농도는 각각 37∼46ppm과 40.600∼464,000ppm으로 매우 높았다. 폐탄광 배수의 유입으로 산성화된 하천수에서는 11∼42ppm의 높은 농도의 Al이 검출되었다. 또한 오염된 지역에서 하상퇴적물중의 Mn, Mg 및 Ca의 농도가 청정지역과 비교해서 현저하게 낮았고, 반면에 하천수 중의 농도는 높았다. A survey was carried out to investigate the contamination of streams by the acid mine drainage originated from the abandoned coal mines and coal refuse piles. The physico-chemical characteristics such as pH, sulfate and elements concentrations in the water and sediment in streams were analyzed. Microbial activity in the sediment was evaluated by measuring dehydrogenase activities. At sites contaminated by acid mine drainage, the pH of the water and sediment declined to acidic range from neutral due to the accumulation of sulfate. the dehydrogenase activity ranged from 12 to 170㎍-TPF·g-dry soil()·24h() at the contaminated sites, whereas uncontaminated sites had activities of 1.176∼4.259㎍-TPF·g-dry soil()·24h(). The dehydrogenase activity was significantly affected by low pH of the sediment, indicating that high concentration of sulfate inhibited microbial activity. The concentrations of heavy metals such as Pb and Fe in contaminated sediment (37∼46ppm Pb: 46,000∼464,000 ppm Fe) were much higher than those in the uncontaminated sediment. The concentration of Al in the contaminated water acidfied by coal mine drainage was in the range of 11 to 42 ppm. Compared with those in the uncontaminated sediment, the concentrations of Mn, Mg, and Ca in contaminated sediment were low because of the leaching from soil to water by the acidfied stream water.
