This study seeks to provide a framework for understanding differential access to medical care. The framework is provided by Anderson Model, a model of health services utilization which suggests a sequence of predisposing, enabling, illness-morbidity characteristics that determine the number of times people will visit a physician. The framework in this study is composed of two models, one is for Adults and the other is for Non-Adults. Models are operationalized using stepwise multiple regression analysis and path analysis. The data come from a national health survey conducted in 1983. The findings of the analysis can be summarized as follows : First, the causal models used in this study are able to explain only a small amount of the variance in medical care utilization(Adjusted $R^2$ is .144 in the Model for Adults and .243 in that for Non-Adults). This finding suggests that we reconsider the utility of such existing model using the predisposing, enabling, and illness-morbidity characteristics in light of their poor correspondence with these data. Second, while small amount of the valiance in medical care utilization is explained, most of the explained variance is due to the illness-morbidity characteristics. The path coefficients of study variables except illness-morbidity variables show these characteristics to be substantially unrelated to medical care utilization, and the indirect effects of the predisposing and edabling characteristics on medical care utilization are also negligible. This casts doubt on the importance of the predisposing and enabling characteristics in explaining medical care utilization. Third, among the predisposing and enabling characteristics, Medical Security variable is the only one having significant direct effect on medical care utilization in both models for Adults and for Non-Adults. Fourth, the amount of the variance explained in the Model for Non-Adults is more than in the Model for Adults. This suggests that medical care utilization of adults is more influenced by behavioral factors than that of children.

The purpose of this paper is to decompose the effect of resources of natural parks(NP) on user's satisfaction to answer the research question: What are the causal effects of resources of natural parks on user\ulcorner After reviewing the literature, classification of resources of NP, various approaches and analysis methods employed, we constructed the conceptual framework and have formulated the hypothesis of this research. We had obtained data through a questionnaire, which surveyed 414 visitors at 6 of the 73 NP in Korea in 2001, based on a stratified sampling method. We have analyzed the data using descriptive statistical methods, Pearson's correlation analysis, and a path analysis method. We found that 1) While the indirect effect of topographical feature and valley(TFV), socio-cultural resources(SCR), and climate, sound, and scent(CSS) turned out to be 2.75, 1.20, and 2.00 times higher than that of wild animal and plant(WAP), the direct effect of TFV, SCR, and landscape turned out to be 2.95, 2.88, and 2.64 times higher than that of CSS, 2) The magnitude of causal effects of the three exogeneous variables of TFV, WAP, and SCR and two intervening variables of CSS and landscape on User's satisfaction turned out to be 0.403, 0.048, 0.323, 0.188, and 0.243, respectively, 3) Total direct effect of the exogeneous and intervening variables on user's satisfaction is 0.871, while that of indirect effect is 0.334, and 4) Causal effect of tangible resources is 1.80 times higher than that of intangible while total effect of tangible resources are 1.36 times higher than that of intangible. The research results suggest that 1) Criteria for designation and maintenances of NP and results of previous studies on resources turned out to be unreliable and distorted, 2) In the criteria of planning and maintenance of NP, intangible resources must be included, 3) Remedial directions to increase user's satisfaction should be focused on maintenance of TFV and landscape in NP, and 4) The approach and path analysis adopted by this research is valid and highly useful for other resource based recreation area. It is recommended that more empirical study on seasonal variation of resources in NP based user's preference be performed in the future.

The purpose of this study was to measure the effects of restaurant service quality dimensions on service value, satisfaction, and behavior intention. A total of 273 questionnaires were completed. A structural equation model was used to measure the causal effects. The results of the study show that the confirmatory factor analysis model presented an excellent model fit. The unrestricted model yielded a significantly better fit to the data than the two restricted models. In the unrestricted model, the effect of reliability on service value was statistically significant. The effects of tangibles and empathy on satisfaction were also statistically significant. As expected, empathy had a significant effect on behavior intention. Moreover, empathy had a significant indirect effect on behavior intention through service value and satisfaction. Restaurants should devote themselves to factors such as reliability in order to improve service value. Also, attention must be given to another important factor, empathy, since this influenced not only satisfaction, but also behavior intention.

The main propose of this research is to examine the performances in ERP introduced enterprises by utilizing BSC model proposed by Kaplan and Norton [1992], to realize this goals, a theoretical review on ERP, BSC, and other related issues is performed in advance, accordingly, research model was generated. In conceptual model analysis, we focused on casual relationships among four performance measurement indicators after introduction of ERP proposed by Kaplan and Norton [2000]. To test the model, structural equation modeling is employed to analyze data collected from 164 enterprises which have introduced ERP for more than 1 year. Survey respondents were confined within the representatives of each enterprise's ERP. Hypotheses proposed in our research are tested by covariance structure model, results are listed as follow : First, learning and growth performance is significant factors for improving both internal process performance and customer performance; second, process performance has a positive impact on customer performance third, despite that customer performance is positively related to financial performance, no direct relationship is found between internal process performance and financial performance, an indirect relationship is built through intermediate medium of customer performance. Based upon these results, we discuss implications at the latter part of paper. Meanwhile, we also provide research limitations, and future research in the final section.

The purpose of this study was to measuring the effects of health involvement, attitude, perceived behavioral control (PBC), behavioral intention on seafood consumption. A total of 235 questionnaires were completed. Structural equation model was used to measure the causal relationships among constructs. Results of the study demonstrated that the structural analysis result for the data also indicated excellent model fit. The direct effect of health involvement on attitude was statistically significant. The direct effects of health involvement, attitude and PBC on consumption were statistically significant. As expected, attitude, PBC and behavioral intention had significant direct effects on consumption. Moreover, health involvement had a significant indirect effect on behavioral intention through attitude and PBC. Health involvement also had a significant indirect effect on consumption through attitude, PBC and behavioral intention. Attitude and PBC had significant indirect effects on consumption through behavioral intention. In conclusion, based on structural analysis, a model was proposed of interrelations among health involvement, attitude, PBC, behavioral intention and seafood consumption. Other variables(sensory variable, habit, norm etc) may be incorporated to form models that consist of new antecedent and consequence pairs.

Government R&D grants for SMEs have risen to three trillion Korean won a year, placing Korea second among OECD nations. Indeed, analysis results have revealed that government support has not only expanded corporate R&D investment and the registration of intellectual property rights but has also increased investment in tangible and human assets and marketing. However, value added, sales and operating profit have lacked improvement owing to an ineffective recipient selection system that relies solely on qualitative assessments by technology experts. Nevertheless, if a predictive model is properly applied to the system, the causal effect on value added could increase by more than two fold. Accordingly, it is important to focus on economic performance rather than technical achievements to develop such a model.

Objectives: This study developed a causal relationship model of herb use from observational data and analyzed the direct and indirect effects of herb use on health according to the model. Methods: A cross-sectional study was conducted with 400 participants aged 26-59 years, selected through multistage random sampling. The instruments used for data collection included demographic information, herb use, health literacy (HL), perceived social support, societal values, and attitudes toward herb use. The conceptual model, hypothesized based on prior evidence, was tested using confirmatory factor analysis through structural equation modeling. Path coefficients were estimated using the maximum likelihood method. Results: The final model utilized empirical data, which showed that perceived social support had the most significant impact on herb use. This was followed by HL, positive attitudes toward herbal remedies, and societal values, with coefficients of 0.31, 0.18, and 0.16, respectively. When analyzing variables that indirectly affected herb use, it was clear that positive attitudes, perceived social support, and societal values significantly influenced herb use through HL, with influence coefficients of 0.08, 0.16, and 0.04, respectively. Together, these variables accounted for 68% of the variance in herb use. Conclusions: The findings from this study can be utilized to develop and implement strategies that guide the use of herbal products, ultimately aiming to improve human health.

The purpose of this study was to examine causal model of resources and demands, family financial management and subjective financial security among urban households based on system theory. For this purpose, the data were collected by the questionnaire sheets. 455 housewives participated this survey in Seoul. And the data were analyzed by various statistical methods such as Frequency, Percentile, ANOVA, F-test, Pearson's correlation analysis, Multipe Regression Analysis, and Path Analysis. The results of this research were as follows: 1. There were significant differences in the Subjective Financial Security according to resource variables and demand yariables. Those variables were such as housewive's age, education, occupation, househead's occupation, per capita income, aspiration, expectancy, perception of financial progress and relative deprivation. 2. The higher family financial management level, the higher level of Subjective Financial security. And the higher family financial management plan·implement level, the higher level of Subjective Financial security. 3. The lower debt/asset ratio, the higher level of Subjective Financial security. 4. Aspiration, per capita income an financial managemant variables showed direct effect on Subjective Financial security among all variables affecting the urban households' Subjective financial security. While housewive's education level, aspiration, per capita income and husband's occupation affected indirectly on the Subjective Financial security through family financial managemant.
