In this paper, we propose goodness of fit test statistics based on the estimated Kullback-Leibler information functions using the data from three step stress accelerated life test. This acceleration model is assumed to be a tampered random variable model. The power of the proposed test under various alternatives is compared with Kolmogorov-Smirnov statistic, Cramer-von Mises statistic and Anderson-Darling statistic.

Kolmogorov-Smirnov (K-S) statistic has been widely used for testing homogeneity of two distributions in the credit rating models. Joseph (2005) used K-S statistic to obtain validation criteria which is most well-known. There are other homogeneity test statistics such as the Cramer-von Mises, Anderson-Darling, and Watson statistics. In this paper, these statistics are introduced and applied to obtain criterion of these statistics by extending Joseph (2005)'s work. Another set of alternative criterion is suggested according to various sample sizes, type a error rates, and the ratios of bads and goods by using the simulated data under the similar situation as real credit rating data. We compare and explore among Joseph's criteria and two sets of the proposed criterion and discuss their applications.

Objectives: The purpose of this study is to identify factors related to unmet dental care needs among Korean youth, enhance the utilization of dental services by adolescents, furnish basic data for youth-oriented dental projects, and improve access to medical care. Methods: The analysis utilized combined data from the basic and oral databases from the 6th (2013-2015), 7th (2016-2018), and 1st year of the 8th (2019) National Health and Nutrition Examination Survey. Results: The factors influencing unmet dental care needs were gender, age, household income level, and health insurance. Statistically significant results were observed in relation to the type of dental clinic, recent visits to a dental hospital, experiences of toothache within the past year, subjective oral health status, occurrences of permanent dental caries, and engagement in orthodontic treatment. Conclusions: When formulating future national policies and projects, it is imperative to consider the factors and underlying reasons for the unmet dental care needs of adolescents. It is also necessary to establish oral health policies and institutional measures tailored to the dental care of adolescents.

Two methods for analyzing interaction between shaped charge jets and targets are taken in AVEAM-MT (ADD Vulnerability and Effectiveness Assessment Model for Materiel Target), which is a model for vulnerability analysis of materiel targets and being developed by ADD. One is an empirical method improved from the Fireman-Pugh technique for rapid penetration calculation into target components. The other is ADD-TSC(ADD Tandem Shaped Charge), which is a physics-based model extended to be applicable for shaped charge jets from the Walker-Anderson penetration model for higher fidelity analysis. In this paper, the two methods are briefly described, and the empirical technique is compared to the physics-based model in the prediction of residual penetration capacity. The latter is also compared to experimental results found in literature in predicting penetration capacity. These comparisons show that both methods can be used for fast calculations or higher fidelity calculations in vulnerability analysis models like AVEAM-MT which is required to perform a considerable amount of iterative simulation for damage analysis.

This study is designed to demonstrate risk factors of unmet medical care for people with cerebrovascular disease. To do this, statistical analysis was performed by using hierarchical logistic regression analysis with SPSS/WIN24.0 program using Korean Medical Panel data in 2014. In the final model of the hierarchical logistic regression analysis, which is based on Anderson's Model, adjusted for the factors of the predisposing and enabling factors, the explanatory variables affecting the unmet medical development are gender, economic activity, income level, the experience of lying in a sickbed, restriction on activity, subjective health condition, and the number of chronic diseases. Based on the results of this study, the practical and policy implications for the effective management and treatment of cerebrovascular disease should be included in the countermeasures for cerebrovascular disease, a strategy to reduce the unmet medical incidence of cerebrovascular disease, in order to meet the medical needs, the necessity of comprehensive measures considering various dimensions of variables and the influential variables of unmet medical emergence have been suggested for the necessity of making a detailed service manual that can improve accessibility to medical services.

This study was conducted to find a practical implication regarding efficient and smooth service utilization including care burden reduction of family caregivers by empirically analyzing the factors influencing the dementia patient home care intention of family caregivers, based on Anderson's behavior model. For this study, the subjects and characteristics suitable for the study purpose were selected using the source data of "A Survey on the Dementia Recognition and Needs" targeting 26 cities and countries in Gyeonggi-do and then secondary analysis was conducted. This study targeted 539 dementia families, and based on Anderson's behavior model, variables related to predisposing factors, enabling factors and need factors were inserted, and hierarchical regression analysis was applied. The analysis result showed that at a significance level of 5%, the home care intention was high when family caregivers were not living in cities, they were spouses or children and their economic level was high as predisposing factors, and the dementia-related attitude was positive as a enabling factor, and the degree of dementia was mild and care burden was low as need factors. Moreover, need factors were relatively important variables among the three factors mentioned above. These findings demonstrate that for improving the home care intention, there is a need to construct a support strategy, which considers the degree of dementia and economic characteristics and develop diverse counseling and education programs for a positive attitude towards dementia and a differentiated strategy depending on regional and family characteristics.

A wide range of health professionals have interest in changing the health behavior of individuals. To intervene effectively and to make informed judgements about how to measure the success of such interventions, health professionals must have an deep understanding of health behavior. This paper provides an overview of the thories of health-related behaviors and the strength and weakness of each, how the theories relate to others, and how they can be used in practice. The theories reviewed include Suchmann's stages of illness experience, Health belief model, Attribution theory, Fishbein's theory of reasoned action, Multiattribute utility models, Consumer information processing, and Anderson's models. Finally, this paper introduces the reader to interesting research findings in our country.

It has been routine practice in regression analysis to check the validity of the assumed model by the use of regression diagnostics tools. Outliers and influential observations often distort the regression output in an undesired manner. Jang and Anderson-Cook (Quality and Reliability Engineering International, 30, 1409-1425, 2014) proposed a graphical method (called a firework plot) so that there could be an exploratory visualization of the trace of the impact of the possible outliers and influential observations on individual regression coefficients and the overall residual sum of the squares measure. This paper further extends a graphical approach to a multi-response surface methodology problem.

While there are many successful cases where application of the TQM model has reaped substantial benefits (Corcoran, 1996; Hayday, 1996 and Massey, 1996), there is little attempt to further develop the TQM model to meet organisations' development needs. The purpose of this paper is introduce the process of development of a fit-for-purpose management system model to meet the development needs of the MTR Corporation Limited, a metro company of Hong Kong. The new management system model is formulated based on the previous research results, on TQM but comprises a new approach to bridging their pitfalls. The formulation of the TMS elements is based on the common factors of four National Quality Awards (Japan, USA, Europe and Australia) and the critical factors developed by seven studies. These studies include those of Saraph et al. (1989), Flynn et al. (1994), Anderson et al. (1995), Powell (1995), Handfield and Ghosh (1995), Black and Porter (1996), and Ahire et al. (1996).

A modified Anderson and Hauck(1983) test for analyzing a two-sequence two-period crossover design in bioequivalence trials is proposed when some observations at the second period are missing. It is based on the maximum likelihood estimators of average bioequivalence model and designed for handling missing at random(MAR) situation. The performance of the proposed test is compared to other tests using Monte Carlo simulations.
