Even though nonhomogeneous Markov Decision Processes subsume homogeneous Markov Decision Processes and are more practical in the real world, there are many results for them. In this paper we address the nonhomogeneous Markov Decision Process with objective to maximize average reward. By extending works of Ross [17] in the homogeneous case adopting the result of Bean and Smith [3] for the dicounted deterministic problem, we first transform the original problem into the discounted nonhomogeneous Markov Decision Process. Then, secondly, we transform into the discounted deterministic problem. This approach not only shows the interrelationships between various problems but also attacks the solution method of the undiscounted nohomogeneous Markov Decision Process.

Since the heat exchange system, such as the boiler of power plant, gas turbine, and radiator require a high rate heat efficiency and the efficiency of these systems is depended on the control methods. However, it is important f3r operator to understand control system of these systems. In order to properly apply control equipment to these process control systems, such as boiler, any other heat process, or process control system it is necessary to understand the basic aspects and operation principle of the process that relate control, interrelationships of the process characteristics, and the dynamics that are involved. Generally, PID controllers are used in these systems but it is difficult for engineer to understand the complex dynamics and the tuning method because of the coupling action and disturbance in the system loop. In this paper, we design an effective experimental system fur automatic control education and analyze its characteristics through experimental system and industrial plant control software to study how they can team automatic control system by experiments.

Since the heat exchange system, such as the boiler of power plant, gas turbine, and radiator require an application of intelligent control system for a high rate heat efficiency and the efficiency of these systems is depended on the control methods it is important for operator to understand control system of these systems and intelligent control technologies. In order to properly apply control equipment and intelligent technology to these process control systems, it is necessary to understand fuzzy, neural network, genetics, and immune as well as the basic aspects and operation principle of the process that relate control, interrelationships of the process characteristics, and the dynamics that are involved. Generally, since PID controllers are used in these systems it is difficult far engineer to understand both the complex dynamics and the intelligent control method. In this paper, we design an effective experimental system for the intelligent control education and analyze its characteristics through experimental system and each intelligent method to study how they can learn intelligent control system by experiments.

Let X and Y be random vectors in R$^{n}$ . A random vector X is 'more associated' than Y if and only if P(X $\in$ A ∩ B) - P(X $\in$ A)P(X $\in$ B) $\geq$ P(Y $\in$ A ∩ B)-P(Y $\in$ A)P(Y $\in$ B) for all open upper sets A and B. By requiring the above inequality to hold for some open upper sets A and B various notions of positive dependence orderings which are weaker than 'more associated' ordering are obtained. First a general theory is given and then the results are specialized to some concepts of a particular interest. Various properties and interrelationships are derived.

This paper is intended as a basic study in which the purpose is to provide understanding of the workings of man in relation to his information resources. Such understanding would prove of value in formulating the policies of an inoformation center serving the fields of science and technology. The information problem of the scientific community was assessed in the lights of the characteristics of the information (cumulativeness, currency versus obsolescence, volume versus redundancy, interrelationships, and foreign literature)and the flow of information and communication patterns covering the use of the variety of media and the information gathering habits of scientists. What can be done to ease the problem was sought in the improvements and innovations which call the attentions of the scientists and the technologists as producers and users of the information, of the professional organizations of various disciplines and of government.

This study was undertaken to understand the interrelationships among customer's perceptions of service encounters, customer value, and behavioral intent in a family restaurant. Based on 331 samples obtained from empirical research, we reviewed the reliability and fitness of a research model and verified three hypotheses using a structural equation model. The results showed that physical environment (${\beta}$ = .418) and a customer interaction with the service provider (${\beta}$ = .265) had a significant effect on the customer's hedonic value. Additionally, physical environment (${\beta}$ = .126) and customer interaction with service providers (${\beta}$ = .264) had a significant effect on customer utilitarian value. Customer's hedonic (${\beta}$ = .538) and utilitarian value (${\beta}$ = .382) triggered by service encounters had a significant effect on their behavioral intent. Limitations and future research directions are discussed.

In recent year, animal welfare is more and more attracted public concern. Many countries have legislated animal welfare laws especially in EU. Now, it is appearing as an international issue in livestock product trade area because of animal welfare standard differences. The concept of animal welfare is not scientific but Ideological. In relation to consumer quality, animal welfare was defined confidential quality attribute. Therefore it is hard to approach to technical quality characteristic. This article reviewed interrelationships of animal welfare and product quality included in animal welfare as a quality factor, the mechanisms of determined quality influenced by animal welfare, relations of the type of animal welfare and quality profiles, and global perspectives.

Software architecture serves as a framework for understanding system component and their interrelationships. Software architectures can be reusable assets to achieve low costs, high productivity, and consistent quality. We have developed a software architecture design environment, called Happy Work. In this paper, we would like to present the structure and functions of Happy Work. Happy Work has two main functions. First, it provides a graphic editor for modeling of software architecture diagram. Second, it provides an ADL, called HWL(HappyWork language). HWL is a language that describes software architecture.

Although there is a little concern about wife beating, the problem is in very serious level. Especially many community workers in urban poor areas reported that they often wittnessed wife abuse cases and most battered women have no place to ask help. However, there is not many systematic analysis on wife abuse in those areas. The purpose of this study are (1) to more accurately estimate the incidence of wife abuse in poor families; (2) to examine the interrelationships of socio economic status, stress and alcohol consumption of wife abuse. The results show that almost 1 out of 3 husbands in urban poor areas carried out 1 or more physical violence acts against their wives during the last year and that social stress has statistically significant relationship with wife abuse in the urban poor families.

The Early Life Problems Scale consisting of 5-point rating for each item was prepared from the results of a questionnaire of 163 items with two sub scales constructed on the basis of Diagnostic Classification: 0-3. Respondents were 361 parents with newborn to 3-year-old children (197 boys and 164 girls). Hypothetical constructs of mental and developmental problems were identified by exploratory factor analysis. The resulting 22 factors explained 58.5% and 72.9% of the common variance for scales I and II, respectively. The rotation procedure yielded 134 items of which 118 had factor loadings of more than .30. Face validity was obtained on the basis of 18 items. The coefficients of correlation between and within factors suggest that there are interrelationships. The reliability of total scales by Cronbach's Alpha was relatively high.
