Normal operation when deeply submerged is a relatively easy task, and human operator control can often provide adequate performance. Near surface depthkeeping, on the other hand, is difficult to both man and machine. Because of the inherent limitation of the human operator, manual control may prove inadequate for near surface depthkeeping in some sea state. This paper describe the control algorithm of an automatic depth control system for submerged body that can be used for both near surface and deeply submerged depthkeeping operations. The computer simulations demonstrate the excellent depthkeeping performance of the controller under seaway effects.

Many studies on safety issues of human-machine interaction are being conducted, especially taking emergency situations into consideration. In light of this view, the importance of objective and reliable measurement of users' reactions under emergency situations is becoming more important than ever in reflecting such issues in the design of everyday things. However, despite the need to consider the human-machine interactions and human performances at the design stage, there were few studies which considered human performances and behaviors under emergency situations. This study is about an evaluation method and design guide to include such human performances under emergency situations during human-machine interactions. This is achieved through an experiment where operators are instructed to press the emergency button at an experimentally designed location under a random emergency situation. By analyzing the results in a human factors perspective, the response time and the accuracy of the operators' behaviors are explained. Analysis revealed that in designing the center fascia for automobiles, there is a tradeoff between response time and accuracy, and the optimal size of buttons differ in each part of the center fascia. This method is expected to be applicable to industrial situations to derive optimal position for emergency buttons.

This paper reports on a study that examined the longitudinal and concurrent effects of the home literacy environment(HLE) on first grade language performance, and the effect of language performance on school adjustment. Study subjects were 469 first graders of 6 elementary schools. The parents' and teacher's reports were used to investigate the subjects' language performance, school adjustment, and the HLE before and after the elementary school entry. Findings from the study show that there is an association between the HLE during the preschool period and the HLE in first grade, and the HLE in first grade positively affects children's language performance. Also the children's language performance had a positive influence on their school adjustment. Therefore, it can be concluded that the HLE during the preschool period is a significant feature that lingers to affect children's language performance and school adjustment.

The main purpose of this study is to examine the impact of intellectual capital disclosure (ICD) on firm performance in the pharmaceutical and chemical industry of Bangladesh. In this study, 21 listed pharmaceutical and chemical companies have been selected as sample for 2016 and 2017. This study used the intellectual capital disclosure index developed by Rahman, Sobhan, and Islam. Return on assets and return on equity have been used as the proxy variable of firm performance. In this study, content analysis is performed to assess the level of disclosure regarding intellectual capital and pooled cross-sectional analysis is used to assess the relationship between ICD and firm performance. The study has found a positive and significant relationship between ICD and firm performance. Besides, an in-depth analysis of this study shows that all the components of ICD namely internal capital disclosure, external capital disclosure, and human capital disclosure are also positively and significantly associated with firm performance. The study suggests the development of an intellectual capital disclosure framework by the regulatory authority for mandatory compliance. This will improve the quality and quantity of ICD in the annual reports. Besides, firms should more emphasize on ICD which will help to improve their performance.

Purpose: This study was conducted to identify factors that affect nursing performance; Those factors are personal characteristics, sub-categories of empowerment and job satisfaction of clinical nurses. Methods: Data were collected from November 24, 2012 to March 11, 2013, and participants were 451 hospital nurses in 6 hospitals. Descriptive statistics, t-test, one-way ANOVA, Pearson correlation coefficient, and stepwise multiple regression were used for data analysis. Results: Nurses who were older, married, highly educated, in the position of charge nurse, and with longer clinical careers showed relatively higher empowerment, higher job satisfaction, and higher nursing performance than others. Also, there were strong correlations between nursing performance and empowerment (r=.576)/job satisfaction (r=.617). Factors predicted nursing performance were relationship with coworkers (${\beta}=.398$), duty (${\beta}=.181$), promotion system (${\beta}=.134$), and turnover intention (${\beta}=-.109$). Factors predicting job satisfaction were competency of empowerment (${\beta}=.249$), and clinical career (${\beta}=.151$). These 6 factors explained 55.2% of the variance in nursing performance (F=93.37, <.001). Conclusion: Regarding human resource management, relationship with co-workers is a changeable factor. Therefore nursing organizations should apply these factors in human resource management to enhance nursing performance and achieve organizational goals.
