In this paper, we consider multi-item inventory management. When managing a multi-item inventory, we coordinate replenishment orders of items supplied by the same supplier. The associated problem is called the joint replenishment problem (JRP). One often-used approach to the JRP is to apply a can-order policy. Under a can-order policy, some items are re-ordered when their inventory level drops to or below their re-order level, and any other item with an inventory level at or below its can-order level can be included in this order. In the present paper, we propose a method for finding the optimal parameter of a can-order policy, the can-order level, for each item in a lost-sales model. The main objectives in our model are minimizing the number of ordering, inventory, and shortage (i.e., lost-sales) respectively, compared with the conventional JRP, in which the objective is to minimize total cost. In order to solve this multi-objective optimization problem, we apply a genetic algorithm. In a numerical experiment using actual shipment data, we simulate the proposed model and compare the results with those of other methods.

The sanitation inspection is the most frequently used procedure to protect foods prepared in foodservice establishments. In order to enhance foodservice inspections and to improve post-inspection remedial measures, more practical evaluation methods for sanitation are required. The HACCP approach is based upon factors which contribute to foodborne disease rather than of factors which relate to aesthetics. Contributing factors for foodborne diseases from food service establishments reported in USA, Candada, and England were analyzed to identify potential hazards during practical foodservice operations. Hazards were classified at critical control points by risk ranking, Twenty-two observable practical indicators relating to each contributing factor were selected and adjusted to standardized procedures and hazard determiners at critical control points, The weights for each inspection item were ranked as 1, 2, 3, 4, or 5 according to the risk level of contributing factors. And also application for the inspection item in different 6 types of work procedures were suggested for the use of specialized foodservice establishment and cafeteria, and of manager's self inspection in each establishment.

Objectives : The purpose of this study is to confirm severe problem caused by using a modified RUCAM scale than that officially recognized to diagnose liver injury induced by herbal medicine. Materials and Methods : Cases with liver injury induced by herbal medicine received to a related institute from January 2004 to December 2007 were collected and evaluated by the original scale and modified scale. Results : 1. Based on this study, we couldn't clinicaly confirm that the case was not excluded by the relieved first item basis of modified RUCAM scale which has to be excluded by the first item basis of orginal RUCAM scale. 2. By modified 6th item, one score was added to the total score. 3. By adding 8th item, it gaind one point to the whole the total score. Conclusions : In this study, we can clinically confirm that the modified RUCAM　application to case with liver injury induced by herbal medicine is a severe problem.

많은 학습시스템이 학습자의 학습효율을 높이기 위하여 학습 난이도를 평가 및 적용하고 있다. 그러나 대부분의 적용방법들은 학습 전 또는 학습 후 학습결과를 분석할 때 산출되어 학습자가 학습도중에 난이도를 변경하면서 학습 콘텐츠를 제공받기 어렵다. 본 연구에서는 학습자의 수준을 학습 과정 중에 적용하고, 이 수준에 맞는 학습 콘텐츠를 다음 학습에 바로 적용시키는 방법을 제시하였다. 이를 통해 학습자는 사전 검사를 통해 설정된 난이도에 따라 다음 학습 콘텐츠를 제공 받을 수 있어 학습향상에 도움이 될 수 있도록 하였다.

The purpose of this research is to analyze the difference of Structural Equation Model which shows the path between BRQ and its performance variables according to purchase product types-fashion brand types, clothing item groups. The subjects were women in their 20s to 40s living in Seoul and Metropolitan areas, and 482 copies of questionnaire were analyzed. Multi-Group Analysis of AMOS 5.0 Package was used to investigate structural equation model according to fashion brand types and clothing item groups. The results of this study were as follows. As for fashion brand types, there appeared to be significant differences between high price brand type and medium-low price brand type for three paths, namely brand satisfaction to brand loyalty, BRQ to brand attitude, and brand attitude to brand loyalty. However the verification of structural equation model according to clothing item groups showed no significant differences between formal wear and informal wear. Consequently, BRQ was proved to affect brand satisfaction and brand loyalty, and brand satisfaction was the important intermediate variable between BRQ and brand loyalty. As consumers were likely to show the difference of structural equation model according to the price of purchase goods, differencial marketing strategy would be suggested.

The age unit knit wear twenties meaning item preference from, thirties and forties appeared with the item which pullover prefers most, fifties selected a cardigan case, an ensemble and the jacket and it prefers with the fact that. It appeared with the style which it prefers most from case P1, P2 all twenties of pullover, the cardigan proposal case appeared with the style which it prefers most from C1, C2 all fifties. From the jacket it appeared with the style which the J1 prefers from fifties-forties. Each age especially the F/W season knit wear the result which examines the wearing objective against, twenties become popular, thirties expression of individuality, forties convenient of activity, fifties for the convenient of activity complement of activity the knit wear with the fact that it wears.

This study was conducted to evaluate the consumers' preferences and perceptions on the salad and its dressings, via a total of 401 subjects in the Taegu area on the basis of 5-point Likert scale. Anthropometric data included the total subjects consisted of 66 females and 335 males: categorized by age, 20's (103), 30's (135). 40's (83), over 50's (80), The average size of family was 4.2 persons. According to BMI, 64.8% of the subjects belonged to the normal group. The age group that liked salad most was the 20's group, which was also the group that ate salad most frequently. The salad was perceived as food item which is convenient to eat(3.83), healthy(3.63), easy to prepare(3.73) and delicious(3.61) but rarely as a expensive item(2.44). The ingredients, used for salad preparation included fruits and vegetables(3.19) such as tomato and cucumber. Among the salad dressings, the fruit dressing was preferred the most(4.59), while the mayonnaise the least(3.59). The mayonnaise was perceived as an item with highest calories(4.1), and hardly perceived as a luxury item(2.78). The preference for the fruits dressing was highly correlated with the degree of education(p<0.05), age(p<0.001) and BMI(p<0.001). The higher the degree of education, the lower the level of age group, and the lower the BMI, the higher preference for the fruit salad dressing was demonstrated.

The purpose of this study was to design a reliable and valid Likert-type scale to measure nuclear energy attitudes of various groups. 8 tests were applied to the construction of a 26-item long form, a 12-item middle form, and a 6-item short form of the scale. Three scales were field tested on 760 respondents representing a diverse range of subjects. The 26-item scale appeared to be reliable, content valid and construct valid. Scale reliability and homogeneity were evidenced by 0.95 coefficient alpha and positive interitem correlations ranging from 0.18 to 0.74. The results of factor analysis and known-groups comparison revealed that this scale had high validity. Reliability of the middle form and short form were evidenced by coefficient alpha of 0.92 and 0.90 respectively. The long and middle forms were strongly correlated, r-value of 0.98 and the long and short forms were also highly correlated, r-value of 0.93. Consequently, long form, middle form and short form scales were evidenced very reliable and valid in measuring nuclear energy attitudes of various groups in general. They can be used for a variety of purpose of measuring and testing nuclear energy attitude.
