The importance of utilizing an effective reward program has been emphasized as a tool for promotional strategies to acquire and retain customers. When consumers participate in a reward frequency program, they tend to focus more on points or mileage than the actual reward itself. This phenomenon is what Hsee, Yu, Zhang, and Zhang (2003) called "medium maximization." In this article, we hypopthesize that the medium effect may disappear when there is a close relationship between the product and the reward as it evokes the correlation of the two directly. The results of the current research show that the medium effect disappears in a strong relation condition while it does exist in a weak relation condition. Furthermore, we found that these results cannot be explained under an alternative "evaluability hypothesis" as Hsee, Loewenstein, Blount, and Bazerman (1999) and Hsee (1996) claimed. Even when we provided price range information as well as medium information, the medium effect still occurred. In this article, we explored boundary conditions for the medium effect and demonstrated the moderating effect of the relationship between products and rewards. Practical implications of the findings were also discussed for designing separate reward programs.

초음파 전파 매개물은 초음파의 손실 없는 투과력을 위한 1차적인 목적 이외에 피부위에서 탐촉소자의 부드러운 이동을 위한 부가적인 목적이 있다. 본 연구는 제형이 다른 진단초음파 전파매개물이 갖는 피부 윤활성, 피부 보습성, 건조속도 등의 초음파 매개물의 특징을 측정하고 비교하였다. 마찰계수는 점도가 높을수록 높았으며 제제의 건조속도는 고분자 수화젤이 가장 높았다. 오일 함유량이 많을수록 수분증발이 나타나지 않았다. 피부수분함량에서는 저점도 에멀전이 높은 수분함량을 나타냈으며 수분함량 감소 정도가 가장 완만히 나타났다. 오일성분을 적절히 사용한 에멀전 형태의 초음파 전파매개물은 피부 보습효과, 피부 유연작용의 피부 건강측면과 피부-탐촉소자간의 피부 윤활성면에서 효과적인 제형임을 알 수 있었다.

When diagnostic ultrasounds are used, an ultrasonic transmission media is used to effectively transmit the ultrasonic energy. Types of ingredients of polymer hydro gel, emulsion, and oil gel were compared with commercialized products by measuring characteristics of ultrasonic transmission media such as skin lubricity, skin moisturizing, and dryness speed which were contained in each different media. The mean friction coefficient measured to investigate skin lubricity showed high in the agent containing a large amount of oil, whereas the mean friction coefficient of the low viscosity emulsion did not show a significant difference with that of the polymer hydro gel. The moisture evaporation measured to investigate the dryness speed of the agent showed highest in polymer hydro gel. This showed that the larger amount of oil it had, the less moisture evaporation occurred. For skin moisture measured to investigate moisturizing characteristics of skin, low viscosity emulsion showed high in moisture content, whereas it showed slowest reduction in moisture content. As a type of emulsion appropriately containing water and oil is superior in skin moisturizing and skin tenderness, it is expected to serve as a dosage form of new ultrasonic transmission media.

The electrochemical reduction of (2,4-difluoro-phenyl)-(2-phenyl-1H-quinolin-4-ylidene)-amine was investigated in 0.1 M tetrabutylammoniumbromide in N,N-dimethylformamide at glassy carbon electrode (GCE) using the technique of cyclic voltammetry at the room temperature (290 K). The reduction of imines occurs in two successive steps, involving one electron in each. In this medium the first peak was observed at about -0.793 V (vs Ag/$Ag^+$) at the glassy carbon electrode surface, which is more stable and well defined as compared to the second peak. The diffusion coefficient ($D_0$) of imine in the investigated solvent media has been calculated using the modified Randles-Sevcik equation. The electron transfer coefficient ($\alpha$) of the reactant species has also been calculated.

본 연구에서는 다양한 동물 모델을 사용하여 Dioscorea daemona Roxb. 줄기 메탄을 추출물(DD)의 항염증 활성을 측정하였으며 DD가 생체내에서 항산화 체계의 변화를 유도할 수 있는지도 살펴보았다. DD를 200mg/kg용량으로 3주간 경구투여하였을 때 동물실험모델에서 항염증 및 type IV 알레르기 억제 효과를 나타내었으며 혈청의 Catalase 활성, 지질 과산화, TG 및 HDL cholesterol 수치가 영향을 받았다. DD와 이를 클로로포름과 부탄올로 순차적으로 분획하여 얻은 fraction이 lipopolysaccharide(LPS)로 유도한 RAW264.7 대식세포주의 nitric oxide(NO), prostaglandin $E_2(PGE_2)$, tumor necrosis $factor-\alpha(TNF-\alpha)$, interleukin 6(IL6)의 생성을 억제하는지도 연구하였다. DD와 그 분획물들은 $4\~100{\mu}g/mL$ 농도에서 세포 독성을 나타내지 않고 LPS가 유도한 RAW264.7 세포주의 NO, $TNF-\alpha$, IL-6 생성을 억제하였다. LPS가 유도한 $PGE_2$ 생성은 DD의 클로로포름 분획에서 유의적으로 감소하였다(p<0.05). 따라서 Dioscorea daemona 추출물은 대식세포의 염증성 매개물의 억제를 통하여 항염증 활성을 나타내는 것으로 사료된다.

경량소재로 사용되는 polyurethane은 난연화 및 강도유지를 위해 난연제, 섬유 및 무기충진제 등을 첨가하거나 고밀도화하여 사용하며 발포시켜 경량화하여 성형된다. Polyurethane 발포체는 자동차 내장재, 건축 구조재, 건축 내외장재, 가구재, 포장재료, 신발, 의류 제품, 단열재 등 다양하게 사용되고 있다. 이러한 polyurethane 발포체는 제조 및 가공의 편리함에 비해 화재발생시 연기발생량이 많고 연소가 용이하여 화재를 전파하는 매개물의 역할을 하여 피해를 더욱 가중시키는 취약점을 가지고 있다. (중략)

This study was carried out to effects of Allium victorials extract on lowering lipid, anti-oxidation and concentration of inflammatory mediators in rats fed high oxidized fat. Concentration of free fatty acid(FFA), triglyceride(TG), total cholesterol and LDL-cholesterol in plasma decreased in the Allium victorials extract groups and plasma HDL-cholesterol concentration revealed a tendency to increase in Allium victorials extract groups. Concentration of total cholesterol and TG in liver showed a tendency to decrease in Allium victorials extract groups. Concentration of thiobarbituric acid(TBARS) in plasma and liver showed a lower values in Allium victorials extract groups than that of control group. Activities of glutathione peroxidase(GSH-Px), superoxide dismutase(SOD) and catalase(CAT) in liver showed a tendency to increase in Allium victorials extract groups. Concentration of nitrogen oxide(NO), ceruloplasmin and ${\alpha}1$-acid glycoprotein in plasma showed a lower values in Allium victorials extract groups than that of control group. These results indicate that the Allium victorials extract have an functional material for lowering lipid, anti-oxidation and anti-inflammatory effect.

In this study, by combining a unique purpose and additional aspects of ultrasonic transmission media, a development potential on a new ultrasonic transmission media was sought. The rheological characteristics and the manufacturing cost for each manufactured formulation were compared and analysed with ready-made. An ultrasonic transmission media is to have different functional characteristics according to the following formulation, it was the best in rheological value, low viscosity emulsion with the oil gel. Polymer hydro gel is can be manufactured at low cost compared to other formulations. Emulsion which shows a sharp viscosity difference according to the components of oil and water had a big difference in manufacturing cost. This study can be utilized as the fundamental data on the ultrasound transmission media equipped with expertise in various areas of ultrasound.
