The purpose of this study is to investigate the effects of through thickness on the mechanical properties and microstructural features in Mod. 9Cr-1Mo steels for RPVs. The microstructures at all locations were typically tempered martensite, but small amount of delta ferrite was observed at the center region. The prior austenite grain size increased with the depth from the surface. The yield strengths of center and 1/4T location were higher than that of surface by 30MPa. The impact toughness of center was low compared to those of other specimens. Also, upper shelf energy was low at the center. The toughness deterioration in center might be caused by larger size of the prior austenite grains and existence of the delta ferrite.

The effect of take-up velocity on the fine structure and properties of PBT fibers are investigated using WAXD, density, birefringence, DSC, dynamic viscoelasticity, TMA, tensile test, etc. An increase in take-up velocity caused an increase in both the density and the birefringence. In the results of WAXD equatorial profiles, the increase in the take-up velocities resulted in the formation of (010) and (100) reflections of $\beta-crystal$ and the reflection peak became sharper at the take-up velocity of 6 km/min. The initial modulus of the fiber increased when the g' fraction increased, the tenacity depended more on fractions of $\alpha-crystal$, i.e. the total crystallinity. The thermal properties of high speed spun PBT fibers were measured with DSC, dynamic viscoelasticity, TMA, etc. Endothermic curves became sharper with increasing take-up velocities, and endothermic melting peaks are shifted to high temperatures. Therefore, crystal structure was well developed in the fiber obtained at high take-up velocities. The $tan\delta$ peak is shifted and the intensity is decreased with temperature. That is, the packing density of the PBT fiber is high when the take-up velocity and orientation of amorphous region is increased. The shrinkage has a tendency to decrease with increasing take-up velocity.

Objectives: This study aims to investigate the factors related to Korean physicians' trust in the government. Methods: We used structured questionnaires that were composed of multidimensional scales for each of the various categories. Results: The recognition levels of trust of the government by Korean physicians were not high, and they ranged from 3.6 to 4.8 for ten scales. The factors related to trust in the government were categorized into seven factors on the basis of a factor analysis. On the regression analysis, a positive relationship was found between "the individual propensity to trust" and trust in the government, while a negative relationship was found between "the recognition level regarding the government as an authoritarian power" and trust in the government. "Confidence about participation in the policy process" as internal efficacy and "belief in governmental ability and motivation toward public demand" as external efficacy also showed a strong positive relationship with trust in the government. Conclusions: From these results, we can draw the conclusion that making efforts to improve the recognition level of trust in the government among physicians is an important policy task. To increase the trust level, participation of physicians in the policy process in various ways and open communication between the physicians' associations and the government should be facilitated.

Objectives : This study was performed to explore customer royalty and the related factors. Methods : 900 households(a 1% sample) were randomly selected from the total population of K city located in Kangwon province. An interview survey was performed with using a structured questionnaire for the subjects(923 persons) who had used medical service during the year before the survey, and the survey was done September, 2002. Results : When comparing the relating factors related with customer royalty according to the sociodemographic characteristics, the older group showed a significantly higher level of recognition for service quality, service reputation, internal customers' attitudes and switching cost. The lower income group showed a higher level of recognition for service quality, service image and switching cost. The lower educated group showed a higher level of recognition for service reputation, service image and internal customers' attitudes. The higher educated group showed a higher level of recognition for perceived risk, and seeking variety. In addition, the expert group or the service and manufacturing workers group showed a higher level of recognition for service involvement. On multiple regression analysis, internal customers' attitudes, service image, service reputation, service quality, switching cost, and substitutability showed significant relations with customer loyalty. Conclusions : This study showed that customer loyalty was significantly influenced by service factors like internal customers' attitudes, service image, service reputation, and service quality, and by market factors like switching cost, and substitutability. The results of this study can be used as a baseline for developing strategies to create and keep customers with high loyalty.

Objectives : The SERVQUAL scale is based on gap theory, which suggests the difference between consumers' expectations and the quality of the medical service actually received. However, problems in the implementation of the SERVQUAL scale have been identified by several researchers. Some researchers have proposed a simple performance-based measure (SERVPERF) or au exportation-controlled performance-based measure(Non-Diff) as alternatives to the SERVQUAL scale. On the basis of the theoretical concerns discussed, we examined the capability of each of the three scales(SERVQUAL, Non-Diff, SERVPERF) to explain variations in consumer satisfaction. Methods : Data was gathered from a self-administered questionnaire in a 430 bed hospital. Questionnaires evaluating medical services were distributed to 180 ambulatory patients. A total of 167 usable questionnaires were gathered. The questionnaire was composed of 10 expectation, performance and expectation-controlled performance items. In addition, overall satisfaction and purchase intention were measured. Results : Compared with the SERVQUAL scale, the Non-Diff and SERVPERF scales better explained the observed variations in consumer satisfaction(SERVOQUAL, $R^2=0.29;\;Non-Diff,\;R^2=0.51;\;SERVPERF,\;R^2=0.48$) and purchase intention(SERVQUAL, $R^2=0.22;\;Non-Diff,\;R^2=0.33;\;SERVPERF,\;R^2=0.34$). Conclusion : The maier conclusion from our study is that the Non-Diff and SERVPERF scales are more efficient in assessing consumer satisfaction than the SERVQUAL scale. Therefore we suggest that consumer satisfaction he measured by the Non-Diff or SEVPERF scales.

Nylon 6-ran-nylon 4 (100/0), (80/20), (70/30) films were prepared by using melt pressing methods. The (N6- ran-N4) films were annealed in the silicon oil bath at 50, 75, 100, 125 and $150^{\circ}C$. The film properties were examined by WAXD, DSC, DMTA and moisture regain. The crystal structure in (N6-ran-N4) films increases the annealing temperature. This is very similar to the alpha phase of nylon 6. The thermal property of (N6-ran-N4) films annealed under high temperature exhibits an increase in the melting temperature and enthalpy. The moisture regain of (N6-ran-N4) films decreased when the annealing temperature was increased.

With the inauguration of a new government, expectations for policy changes are also rising. In the hope that this will serve as an opportunity to improve health care policy, I would like to outline the principles strategies. First, considering the growing socioeconomic impact of the health care sector, the government's policy priorities should be notably increased compared to the past. Second, policy improvement measures based on evidence should be sought instead of dwelling on presidential pledges. While easing regulations, we should improve the quality of regulatory approaches. Therefore, it is a time when efforts are needed to strengthen the stability of policies in response to economic crises.

Objectives : To assess the impacts of implementing case payment system (CPS) to Medical Aid (MA) hemodialysis patients on the frequencies and expenditure of dialysis. Methods : Fifty-eight clinics and 35 tertiary care hospitals were identified as having a minimum of 10 hemodialysis patients for each of the MA and Medical Insurance (MI) programs, who received hemodialysis from the same dialysis facilities for both periods of July 2001 and July 2002. From these facilities, a total of 2,167 MA and 2,928 MI patients were identified as the study subjects. Using electronic claims data, the changes in the total number of monthly treatments and charges for outpatient hemodialysis treatments for each patient after the introduction of the CPS were compared between the MA and MI patients. Multiple regression analyses were performed to examine the independent impact of the CPS on the utilization and expenditure of dialysis treatments among the MA patients. Results : There was a significant decrease in the total charges for the hemodialysis treatments of the MA patients, 3.4% (p<0.05), whereas a significant increase was observed for the MI patients, 2.5% (p<0.05). For both the MA and MI patients, the frequency of the monthly hemodialysis treatments were significantly increased, 5.5 (from 12.1 to 12.7) and 7.8% (from 11.6 to 12.5), for the MA and MI patients, respectively. However, a multivariate regression analysis showed no significant difference in the changes in the total number of monthly hemodialysis treatments between the MA and MI patients after implementation of the CPS. Another regression model, regressing on the changes in the monthly claims of dialysis treatments, showed a significant negative coefficient for the MA ((=-70725, p<0.05). Conclusion : The significant decrease in the total charges for hemodialysis treatments among MA as compared to MI patients suggests that there was a cost reduction in the MA program following the introduction of the CPS.
