  • This study aims to provide distributors with several implications on the channel strategy by testing factors which influence on the offsetting investment. Medium-sized distributor facing a relatively inferior power can cause profit vulnerability from large manufacurer's opportunistic behaviors. At the same time, we tested the relationship commitment to the relation with manufacturer as another alternative strategy taken by medium-sized distributer. For this research, samples from dealers in oil-petroleum refinery industry were selected and the data was collected using mail survey. The data was analyzed utilizing validity test, reliability test, factor analysis, correlation analysis and LISREL. The major analyzed results are as follows: First, the offsetting investment of preventing loss from manufacturer's opportunism didn't affect medium-sized distributor's sales empirically. Second, the hypothesis that the more the medium-sized distributor's transaction specific assets which they invest in the transactional relationship with manufacturer, the more the safeguard against the expected opportunism of manufacturer was not supported by the results. Third, the more use of coercive power by the manufacturer, the more increase in the perception of expected opportunism of manufacturer by the medium-sized distributor, it make stimulates offsetting investment as safeguard by medium-sized distributor and it has negative effect on developing commitment. Finally, the large manufactures dealing with a medium-sized distributor firm which had a reputation of fairness didn't make offsetting investment as a response for distributor's opportunism.

  • Purpose: This study was conducted to identify the association of dietary intake levels with ante-natal depression among pregnant women. Methods: Secondary data analysis was done using Can Pro software (version 3.0) to evaluate the diet intake levels with 24 hour recall diary method with 130 pregnant women visiting a general hospital. Statistical analysis included descriptive statistics, t-test, Mann-Whitney U test and adjusted logistic regression using the SPSS/WIN program. Results: Whole dietary intake levels of pregnant women were insufficient according to Recommended Nutrient Intake (RI) with the except of phosphorus intake. There were significant differences in RI by gestation period and high risk pregnancies. Non-depressed women showed more intake in niacin (z=1.33, p=.018) and zinc (t=3.99, p=.048) than depressed women did. Niacin was a significant determinant of ante-natal depression (Exp (B)=5.88, p=.47, 95% CI [1.02~23.83]). Conclusion: Dietary intake assessment would be necessary during pregnancies for the screening of ante-natal depression. For ante-natal depression care, a tailored dietary intervention should be applied for women with insufficient nutrient intake.

  • The purpose of this study is to investigate and compare the validity and the reliability of the visual simulation method using the internet. For this. the evaluation of the artificial and natural landscape through the medium of color slides are compared with the internet survey. Data is analysed through the comparison of t-test between the two media by landscape type, and spatial image is analysed by factor analysis algorithm. Principle component analysis using Varimax Method is applied for extraction and factor rotation respectively. The results of this study can be summarized as follows; There are no statistical differences between the two methods with artificial and natural landscape in the total data that included second tests. Factors covering the spatial image are found to be \`aesthetic\`, \`spatial shape\`, and \`familiarity\`. Total variance is obtained as 66.4%. There are no statistical differences between the two methods in 2/3 of the cases. In the case of far view of artificial landscape, the results of the t-test show that the two methods are exactly the same. Especially in the case of the artificial far landscape shows no difference of all factors between two methods. There are no differences between first and second tests of the same media and the same landscape type. And it shows the reliability of this method. These results suggest that the probability that the internet can be used as a medium of landscape evaluation and gathering information on anyone\`s landscape image. Simulation techniques with the internet survey method should be further developed for practical application.
