In traditional inventory models, purchase prices of raw materials are assumed to be fixed and have no effect on the optimal choice of inventory policies. However, when purchase prices fluctuate continuously over time, inventory costs are heavily affected by purchasing prices. Risk-averse inventory model decides order quantity and ordering time by considering not just purchase prices but also the risk from the discrepancy between estimated prices and realized prices. In this paper, we propose a myopic inventory policy which incorporates price risk into deciding ordering time and quantities. While the existing risk-averse model has no mechanism to reallocate inventories already purchased for a specific future period, the revised one reallocates initial inventories of each period to other future periods so that it can avoid purchasing raw materials at high prices. Experimental results demonstrate that the revised model outperforms the existing one in respect of total cost and variability.

Conclusions - We find the dynamic effect of the EPU indexes in the US and China on the macroeconomics returns in Korea. This study has an empirical evidence that the economy market in Korea is influenced by the EPU index of the US rather than it of China. The higher EPU, the more risky the economy of in Korea.

Male respondents present high mean scores on external involvement items, emphasizing social roles of clothing. Two involvement factors generate three market segments: high involvement group(32.4%), external involvement group(44%), and low involvement group(23.6%). Second, high involvement group shows higher mean scores on purchase intention of seven clothing items than low involvement group. Third, department store attributes are identified into four factors, product assortment, quality per price, service, and symbolic image, while internet shopping mall includes assortment & convenience, quality per price, and symbolic image. High involvement group again presents higher mean scores on each retail attribute factor than low involvement group. Finally, quality per price is the most significant variable to explain the purchase intention at department store among three market segment, whereas assortment & convenience and quality per price are important predictors to increase purchase intention at internet shopping mall.

The research questionnaires selected from the pilot study were administered to 547 female subjects in the age of twenties. The dissatisfaction factors identified as a result of the factor analysis were as follows: (1) 'price' factor ($21.6\%$ of the total explained variance), (2) 'product assortment' factor ($21.5\%$), (3) 'purchase decision-making' factor ($19.9\%$), (4) 'quality' factor ($18.6\%$), (5) 'informa­tion and service' factor ($18.4\%$). By these five factors, the $34.7\%$ of the total variance were explained. The factors were validated by the multiple regression analysis. The purchase decision­making factor has the greatest explanatory power suggests that psychological aspects are more important to clothing dissatisfaction than any other objective aspects. The relationships between the dissatisfaction factors and the selected variables were found to be as follows: 1) The higher clothing importance scores, the higher product assortment related dissatisfac­tion score. 2) The higher the purchase price, the lower the price related dissatisfaction, but the higher the product assortment related dissatisfaction scores. 3) The department store and the national brand chain store shoppers had higher product assortment related dissatisfaction compared to the small retail store and discount store shoppers.
