This study aims to investigate the relationship between the variables of Current Ratio (CR), Return-on-Equity (ROE), Return-on-Assets (ROA), Debt-to-Equity Ratio (DER), and Firm Size (FS) on Dividend Policy (DP) in real estate and property companies listed on the Indonesia Stock Exchange in the period 2016-2019, looking at nine real estate companies in Indonesia. The research methodology uses an explanatory analysis approach and linear regression. Based on the eligibility and homogeneity of the data, the number of sample companies selected was nine companies. The company's financial statement data derived from primary data obtained on the Indonesia Stock Exchange, such as current ratio (CR), return-on-equity (ROE), return-on-assets (ROA), debt-to-equity ratio (DER) and firm size and dividend policy variables. The data analysis procedure is first to transform financial data from the original ratio data into interval data and, then, transform it to ordinal data. Furthermore, the validity and reliability process are ignored because the data is primary. Finally, regression testing is part of the hypothesis testing stage. The results of this study showed that the CR, ROE, and firm size had no positive and significant effect on dividend policy. In contrast, DER and ROA have a positive and significant impact on dividend policy.

The paper presents a study aimed at understanding some characteristics of an interior explosion within a room with limited or no venting. The explosion may occur in ammunition storage or result from a terrorist action or from a warhead that had penetrated into this room. The study includes numerical simulations of the problem and analytical derivations. Different types of analysis (1-D, 2-D and 3-D analysis) were performed for a room with rigid walls and the results were analyzed. For the 3D problem the effect of the charge size and its location within the room was investigated and a new insight regarding the pressure distribution on the interior wall as function of these parameters has been gained. The numerical analyses were carried out using the Eulerian multi-material approach. Further, an approximate analytical formula to predict the residual internal pressure was developed. The formula is based on the conservation law of total energy and its implementation yields very good agreement with the results obtained numerically using the complete statement of the problem for a wide range of explosive weights and room sizes that is expressed through a non-dimensional parameter. This new formula is superior to existing literature recommendations and compares considerably better with the above numerical results.

Purpose: The purpose of this study was to identify the conceptual structure of stressors experienced by nursing students during clinical practice. Methods: Ten men and 10 women nursing college students were interviewed. The results were 208 ideas. By synthesizing and editing these ideas, the final statement was trimmed down to 39 questions. The next step was to have the participants classify these 39 final questions. They were asked to rate stress scores using a five-point scale. Through multidimensional scaling analysis and hierarchical cluster analysis yielded dimensions and clusters. Results: Results of the study showed 2 dimensions which were classified as 'interpersonal relationship-practice system' and 'identity-practice environment'. It also yielded 8 clusters which were classified as 'role confusion', 'gender discrimination', 'attitudes of medical personnel and patients', 'comparison between fellow students', 'difference between theory and practice', 'disestablishing the role of practice guide', 'interference with training', and 'problems of the practice environment'. Further, stress factors and stress levels were differentiated depending on the gender of the student. Conclusion: The results of the study indicate that educators who are developing clinical practice programs and clinical practitioners should consider stressors during clinical practice and the educational implications to nursing students.

Over the years, probabilistic risk assessment (PRA) research activities conducted at the U.S. Nuclear Regulatory Commission (NRC) have played an essential role in support of the agency's move towards risk-informed regulation. These research activities have provided the technical basis for NRC's regulatory activities in key areas; provided PRA methods, tools, and data enabling the agency to meet future challenges; supported the implementation of NRC's 1995 PRA Policy Statement by assessing key sources of risk; and supported the development of necessary technical and human resources supporting NRC's risk-informed activities. PRA research aimed at improving the NRC's understanding of risk can positively affect the agency's regulatory activities, as evidenced by three case studies involving research on fire PRA, human reliability analysis (HRA), and pressurized thermal shock (PTS) PRA. These case studies also show that such research can take a considerable amount of time, and that the incorporation of research results into regulatory practice can take even longer. The need for sustained effort and appropriate lead time is an important consideration in the development of a PRA research program aimed at helping the agency address key sources of risk for current and potential future facilities.

This study examines the relationship between employee engagement and goal orientation toward competence. In addition, it also examines the relationship between competence and employee performance in financial institutions in Indonesia. Questionnaires were distributed to several employees who work at financial institutions in Aceh, North Sumatra, and Riau. The basis for selecting the research object was that most financial institutions have similar business products. The similarities are the marketing of home loan ownership products and multipurpose investments. The three study regions are located in western Indonesia's most central provinces and have a significant amount of trade. The sampling technique used was purposive sampling based on specific criteria for the respondents. 275 employees made up the research sample, and partial least squares data analysis methods were applied. In data analysis, initial testing was carried out on the components of the research statement items to see their validity and reliability. The results of this study indicate that employee engagement behavior can improve employee performance, which improves financial institutions' organizational performance. The study's findings offer suggestions for policies and guidelines that will encourage productive work behavior among employees and boost organizational performance. The fact that employees must think and act creatively to develop their competence and become superior employees is another distinctive feature of this research.

Occupational safety and health management expenses in the construction industry are statutory and separately included in the cost statement to prevent occupational accidents and health problems. The expenses are determined by multiplying the standard amount by the rate decided according to construction types and scales. However, the current expense appropriation method does not properly reflect the recent changes in the construction industry such as industry size, industry diversification, and social atmosphere about safety reinforcement. This study surveyed 1579 questionnaires in total and analyzed expense execution rate and proportion of each expense category. The expense execution rate was relative higher in complex construction (e.g., heavy construction = 126%, civil engineering = 125%) and long-period project (equal to or over 48 months construction = 133%) compared to general construction (98~116%) and short-period project (less than 48 months construction = 115%). The proportion of spending expenses was higher in the category of safety manager labor costs (25~52%), safety facility costs (22~40%), and personal protective equipment costs (10~25%). The analysis results of the study can be utilized in revising the standard expense appropriation method by reflecting the current usages of the occupational safety and health management expenses in the construction industry.
