The Purposes of this study ar (1) to identify types and levels of channel conflicts between an apparel manufacturer and a franchised agency, (2) to investigate the effect of economic dependence on conflicts, and (3) to examine the effect of conflicts on satisfaction in a franchised agency's perspective in distributive channel of Korean apparel industry. For this study, questionnaires were administered to the owner or manager of 300 franchised agencies. Employing a sample of 209, data were analyzed by using means, factor analysis, pearson correlation and multi-regression analysis. Major findings are as follows: 1) Types of conflicts between apparel manufacturers and franchised agencies are identified as goal divergence, difference in perception, ineffective communication and lack of role clarity. The highest level of conflicts are lack of role clarity, followed by goal divergence, difference in perception and ineffective communication. 2) Economic dependence leads to channel conflicts in part. Greater levels of economic dependence foster greater conflicts such as lack of role clarity and lower conflicts such as ineffective communication. 3) With respect to effect of conflict on satisfaction, the greater the levels of conflict, the lower the degree of satisfaction with ole performance and with business decision and overall satisfaction.

The objective of this research was to study the optical illusion effect and the difference of image of textile pattern design. This research also tried to show the more useful method to make stimulus by computer simulation and to present quantitative data. For the experiment, 3 design variable were selected from design principal book as follows : size, arrangement and value harmony of motive. Size of motive variable was divided into 3 level so by use of check & dot pattern, arrangement of motive variable was manipulated to vias direction for check pattern and value harmony between motive & base color was classified into similar value harmony and contrasting value harmony. Visual stimuli which same model was wearing each design were created by ENVISION program. This photographs were given to evaluating panels, Then panels compared experiment design by slim effect and evaluated for 5-sementic differential scale expressing clothing image. The results were as follows : 1) There were significant difference is slim effect, clothing image as simplicity and boldness according to size of Motive. 2) Arrangement of motive for check pattern had significant effects on slim , clothing images as activity and attractiveness. 3) Case of low value base color and high value dot color has significant high score on slim effect, activity, attractiveness, boldness and youthful image.

Tensile residual stress happen by difference of coefficients of thermal expansion between fiber and matrix is one of the serious problems in metal matrix composite(MMC). In this study, TiNi alloy fiber was used to solve the problem of the tensile residual stress as the reinforced material. TiNi alloy fiber improves the tensile strength of composite by occurring compressive residual stress in matrix using shape memory effect of it. Pre-strain was added to generate compressive residual stress inside TiNi/A16061 shape memory alloy(SMA) composite. It was also evaluated the effect of compressive residual stress corresponding to pre-strains variation and volume fraction of TiNi alloy. AE technique was used to clarify the microscopic damage behavior at high temperature and the effect of pre-strain difference of TiNi/A16061 SMA composite. In addition, two dimensional AE source location technique was applied to inspect the crack initiation and propagation in composite.

Matrix-induced mass bias and its effect on the accuracy of isotope ratio measurements have been examined for a quadrupole-based inductively coupled plasma-mass spectrometer (Q ICP-MS). Matrix-induced mass bias effect was directly proportional to % mass difference, and its magnitude varied for element and nebulizer flow rate. For a given element and conditions in a day, the effect was consistent. The isotope ratio of Cd106/Cd114 under $200{\mu}g\;g^{-1}$ U matrix deviated from the natural value significantly by 3.5%. When Cd 111 and Cd114 were used for the quantification of Cd with isotope dilution (ID) method, the average of differences between the calculated and measured concentrations was -0.034% for samples without matrix ($0.076{\mu}g\;g^{-1}$ to $0.21{\mu}g\;g^{-1}$ for the period of 6 months). However, the error was as large as 1.5% for samples with $200{\mu}g\;g^{-1}$ U. The error in ID caused by matrix could be larger when larger mass difference isotopes are used.

This study is concerned with the mechanism of PTCR in $BaTiO_3$ ceramics doped by $Nb^{+5}$ Since the vacancy compensation layer at the grain boundary of n-type doped $BaTiO_3$ ceramics has been known as a major factor for surface state to give PTCR phenomena the dependence of PTCR on such vacancy compensation layer was attemped to be confirmed experimentally in this study. For the experiment quenching and annealing at various temperature after sintering were adopted to induce difference in the thickness of vacancycompensation layer so as to exihibit difference of PTCReffect eachother. The TEX>$Ba^{++}$ cocentration at the grain and grain boundary was measured by EDAX to confirm the formation of the vacancy compensation layer. It was found that i)either decrease in the temperature for quenching ii) or increase in the temperature for annealing improves the PTCR effect clearly iii)increase in TEX>$Ba^{++}$ concentration at the grain boundary results in the improvement of PTCR effect. It was concluded that all the experimental results gave the evidence for the dependence of PTCR effect on the vacancy compensation layer at the grain boundary which had been induced possibly by the $Ba^{++}$ diffusion by the heat treatment conducted.

Objectives : To identify potential correlation between patients' expectations and clinical outcome in a randomized control study of acupuncture. Methods : In a clinical trial of acupuncture for hypertension, 60 participants with pre and mild hypertension were randomized into an acupuncture group and a control group. After randomization, all participants were asked to rate their expectation for the intervention on a scale of 0 to 10. To analyze the effect of expectation on clinical outcome, change of blood pressure was compared between high and low expectation groups. Results : There was no significant difference of baseline blood pressure between low expectation group and high expectation group. Proportion of acupuncture group and control group was also not different between low and high expectation groups (p = 0.638). The change of systolic blood pressure was -1.55 mmHg in low expectation group and -3.07 mmHg in high expectation group, and it was not significantly different (p = 0.54). There was no significant difference in the change of diastolic blood pressure between two groups (p = 0.58), with -3.24 mmHg in low expectation group and -2.34 mmHg in high expectation group. Conclusion : In this study, the expectation of intervention (including acupuncture treatment) was not associated with the effect of intervention.
