Diurnal variation in faecal chromic oxide levels was estimated from 4 hourly faecal sampling of 56 wethers allotted to one of six different feeding patterns. Sampling occurred on days 6 and 7 (Period 1) after a controlled release device was administered, and was repeated on days 14 and 15 (Period 2) following re-randomisation of the wethers to the feeding patterns. Increasing the frequency of feeding tended to be associated with higher faecal chromic oxide levels (p < 0.05), particularly in wethers fed thrice daily at 8 hour intervals. There was no interaction between feeding pattern and period, sampling day or time within-day. There were significant period x time within-day (p < 0.05) and day x time within-day (p < 0.001) interactions, indicating that variation in faecal chromic oxide between sample times was not consistent. This implies that sampling at any time of day is unlikely to result in a biased estimate of pasture intake, providing sufficient samples are collected. Significant period (p < 0.001) and period x day (p < 0.01) effects were associated with slow faecal chromic oxide equilibration in period 1. Equilibration did not occur until after day 7, indicating a need for caution when commencing sampling.

This study was to confirm the mechanism through which the career preparation behaviors are determined by identifying the structural relationship between influential variables on the career preparation behaviors of college students majoring in security service, and to offer proposals for promoting their career preparation behaviors based on the research results. With this aim, the study analyzes the effect of career decision-making autonomy, satisfaction with a major, and satisfaction with martial arts training on career identity, as well as the influential relationship concerning the effect of career identity on career preparation behaviors. For this, the study set as a population college students majoring in security service in the Gyeonggi region. As a subsequent sampling method, the study selected 300 students through purposive sampling. Then, excluding 13 copies of which the answers were insincere, 263 copies were used for data analysis. The detailed results include the following. First, regarding career decision-making autonomy, it was discovered to have a positive (+) effect on career decision-making self-efficacy. Second, whereas satisfaction with a major had no significant effect on career decision-making self-efficacy, it had a negative (-) effect on career preparation behaviors. Third, satisfaction with martial arts training was found to have a positive (+) effect on career decision-making self-efficacy. Fourth, career decision-making self-efficacy had a positive (+) effect on career preparation behaviors. Fifth, career identity had a negative (-) effect on career preparation behaviors.

The purpose of this study was to examine the moderating effect of attitude toward green brand on green brand positioning and repurchase intention of environmentally friendly products, product knowledge on attitude toward green brand and the effect of green product knowledge on green repurchase intention. This study uses a structural equation approach with a sample size of 175 and uses an eight-point Likert scale. The data collection technique used purposive sampling. The criteria for respondents are to use environmentally friendly cosmetic products and the respondents live in Central Java and have consumed more than two times. Online sampling using google form. Data were analyzed using statistical software AMOS 22. The results showed that green brand positioning has a significant effect on repurchase intention. Attitude toward green brand has a positive effect in mediating the relationship between green brand positioning and repurchase intention. Similarly, green brand knowledge has a positive effect on attitudes, although green knowledge has no positive effect on repurchase intention. Product positioning in the minds of consumers is important in shaping attitudes. It is important for companies to continue to develop environmentally friendly products so that product positioning can be distinguished from competitors' products.

This study investigates the effect of job satisfaction as a mediator of job placement on employees' organizational commitment in the Sumatra-Indonesia energy sector. Permanent personnel of a PGU unit power plant in Sumatra, Indonesia, made up the population and sample. The sampling technique used was saturated sampling of 129 employees. The research model and hypotheses were tested using multiple regression analysis. This study indicate that job placement has a significant positive effect on job satisfaction. Simultaneously, job placement does not have a significant positive effect on organizational commitment. Secondly, job satisfaction has a significant positive effect on organizational commitment and finally, job satisfaction mediates the relationship between job placement and organizational commitment. The results of this study indicate that job placement has a significant positive effect on job satisfaction. Therefore, the right job placement will lead to employee job satisfaction. Another finding is that job placement has a positive and insignificant effect on organizational commitment. Furthermore, job satisfaction has a significant positive effect on organizational commitment. The results of this study indicate that the higher the job satisfaction of the PGU unit employees in the Sumatra area, the higher the level of employee organizational commitment will be.

Recently, the active interaction control (AIC) system was proposed as a semi-active control system. The AIC system consists of a primary structure and an auxiliary structure. The objective of the AIC system is to control the response of the primary structure through engagement and disengagement between the primary and auxiliary structures. Previous switching control algorithms have been shown to be effective in reducing the response of the primary structure. However, they have the main drawback of requiring an excessive engagement-disengagement frequency and high interaction force. In this paper, the regions in which the switching is activated and the regions in which the switching is deactivated are described separately, to effectively determine the engagement or the disengagement. The general relationship between the switching regions and the deactivated switching regions selected according to the engagement-disengagement conditions is described within the newly-developed comprehensive switching framework. The proposed engagement-disengagement conditions are designed within a comprehensive switching framework, to reduce engagement-disengagement frequency and interaction force. Furthermore, the effect of a control sampling period on the AIC system is explained in terms of the engagement-disengagement frequency. The effectiveness of the proposed algorithms and the effect of the control sampling period are considered for a single degree of freedom model under free vibration. It is observed that increasing the duration of stay by using a large control sampling period prevents the AIC system from activating the possible chance of switching. The proposed algorithms are shown to be effective, both in restricting ineffective switching and in reducing interaction force.

An empirical Bayesian approach is discussed for estimation of characteristics from the two-way balanced rotation sampling design which includes U.S. Current Population Survey and Canadian Labor Force Survey as special cases. An empirical Bayesian estimator is derived for monthly effect under presence of two types of biases and correlations It is shown that the marginal distribution of observation provides more general correlation structure than that frequentist has assumed. Consistent estimators are derived for hyper-parameters in Normal priors.

This paper deals with a mixed logit model for vaccination data. The effect of a newly developed vaccine for a certain chicken disease can be evaluated by a noninfection rate after injecting chicken with the disease vaccine. But there are a lot of factors that might affect the noninfecton rate. Some of these are fixed and others are random. Random factors are sometimes coming from the sampling scheme for choosing experimental units. This paper suggests a mixed model when some fixed factors need to have different experimental sizes by an experimental design and illustrates how to estimate parameters in a suggested model.

Skip-Lot sampling plan is formulated in terms of renewal process. This approach facilitates studying the average outgoing quality in a short production run of length t, AOQ (t). By numerical studies it is found that the long-run average outgoing quality (AOQ) greatly overestimates AOQ (t) for short runs.
