We consider the question of efficiency of the Bayes sequential procedure with respect to the optimal fixed sample size Bayes procedure in a simple vs. simple testing problem for data coming from a general nonregular density b(.theta.)h(x)l(x < .theta.). Efficiency is defined in two different ways in these caiculations. Also, the minimax sequential risk (and minimax sequential stratage) is studied as a function of the cost of sampling.

Sensory analysis of milk and milk products is widely appreciated, and there is a demand for experts with these skills in the dairy industry. To this end, it is important to understand the basic principles of sensory analysis and impart training to facilitate the development of dairy food industry. This paper addresses the ISO 22935/IDF 99 guidelines on the methodology of sensory analysis of milk and milk products, training procedures and monitoring of selected assessors, and criteria for sampling and preparation of dairy samples and their assessment.

We consider Bayesian models allow multiple grouping of parameters for the normal means estimation problem. In particular, we consider a typical Bayesian hierarchical approach based on thepartial exchangeability where the components within a subgroup are exchangeable, but the different subgroups are not. We discuss implementation of such Bayesian procedures via Gibbs sampling. We illustrate the proposed methods with numerical examples.

This paper presents a design method for PID controller using optimal control theory. The procedures of the applied method consist of (1) sampling the system response to the test signal, (2) processing the sampled data using RPE method to identify the parameters of the plant, (3) calculating the optimal value of the PID controller parameters using LQ theory. This controller is implemented on the digital computer and applied to real servomechanism, yielding satisfactory result.

Some rank score tests are proposed for testing the equality of all sampling distribution functions against ordered location-scale alternatives in k-sample problem. Under the null hypothesis and a contiguous sequence of ordered location-scale alternatives, the asymptotic properties of the proposed test statistics are investigated. Also, the asymptotic local powers are compared with each others. The results show that the proposed tests based on the Hettmansperger-Norton type statistic are more powerful than others for the general ordered location-scale alternatives. However, the Shiraishi's tests based on the sum of two Bartholomew's rank analogue statistics are robust.

In this paper, we consider a Bayesian forecasting method for the analysis of repeated surveys. It is assumed that the parameters of the superpopulation model at each time follow a stochastic model. We propose Bayesian prediction procedures for the finite population total under dynamic generalized linear models. Some numerical studies are provided to illustrate the behavior of the proposed predictors.

This study was designed to find the characteristics and patterns in subjectivity of an attitude on the degree of importance of professional nursing for advancing nursing image. Q-methodology was used as a research design and the research procedures were as follows. Q-sampling has been derived from the literature review and interview. Its credibility and validity were also tested by nursing professors. Total of 34 statements were selected. P-sampling has been drawn and 32 samples were selected. Based on 9 point scale. the selected respondents rated their operant definition on the degree of importance of professional nursing for advancing nursing image. The results of above procedures were analyzed by PCQ program. The attitude about the degree of importance of professional nursing for advancing nursing image were analyzed based on the typical array. extreme comments. and the demographic information of study subjects. The results revealed that there were four types of attitude about the degree of importance of professional nursing for advancing nursing image. The four types were named as follows; 1) The first type. agree of problem-solving perspectives. was consisted of 8 subjects. They emphasized that the nurse should solve a patient's problem promptly and precisely for advancing nursing image. 2) The second type. agree of kindness perspectives. was consisted of 5 subjects. They insisted that the nurse should be kind to patient and his family for advancing nursing image. 3) The third type. agree of love and service perspectives. was consisted of 4 subjects. They emphasized nursing spirit based on love and service for advancing nursing image. 4) The fourth type. agree of professional knowledge perspectives. was consisted of 6 subjects. They emphasized that the nurse should construct of professional nursing knowledge for advancing nursing image. As a result. this study discovered three types of the degree of importance of professional nursing for advancing nursing image. By identifying the nature of each of four types. this study can be useful to develop efficient strategies for advancing nursing image.

This study was carried out to find out any inherent problems occurring in the sampling and analytical procedures, and to suggest the relevant solutions to the problems. In addition, an optimal condition of clean-up process was developed, which was based on a method using silica glass column. As a result of experiments to test any artificial contamination of blank samples such as glassware and collection media, artifacts of DBP and DEHP appeared to be detected in various kinds of laboratory tools and apparatuses used in the sampling and analytical works. Therefore, it is necessary to investigate a degree of contamination before laboratory works by conducting a prior check any possible contaminations in all experimental tools and apparatus. It is also necessary to devise a method to avoid a tool, if possible, or to use a substitute of phthalate free. If the use of any plastic tool to cause contamination is inevitable, it should be properly corrected with a blank level, as is equally treated as the sample. The clean-up process demonstrated in this study can give us a significant benefit in terms of the quantity and quality of a target compound by GC/MS analysis.

This study was designed to find the characteristics and patterns in subjectivity of an attitude on the induced abortion before marriage in women for a university student. Q-methodology was used as a research design and the research procedures were as follows. Q-sampling has been derived from the literature review and interview. Its credibility and validity were also tested by nursing and methodology professors. Total of 34 statements were selected. P-sampling has been drawn and 49 samples were selected. Based on 9 point scale, the slected respondents rated their operant definition on the induced abortion before marriage in women. The results of above procedures were analyzed by PCQ program. The attitude about the induced abortion before marriage in women were analyzed based on the typal array, extreme comments, and the demographic information of study subjects. The results revealed that there were three types of attitude about the induced abortion before marriage in women. The three types were named as follows ; 1) The first type, agree of conservative perspectives, was consisted of 15 subjects. They emphasized the sanctity of human life and the right of life that will never allow the killing fetus and prevention of induced abortion. 2) The second type, agree of liberal perspectives, was consisted of 10 subjects. They insisted the right to choice for women to control their body, so women have appropriate reason, they could choice induced abortion. 3) The third type, agree of compromise perspectives, was consisted of 7 subjects. They emphasized prevention of induced abortion but allowed under social permission. As a result, this study discovered three types of the attitude about the induced abortion before marriage in women. By identifying the nature of each of these types, this study can be useful to develop efficient strategies for preventing induced abortion.
