It is important to understand the amount of time required to execute an emergency procedural task in a high-stress situation for managing human performance under emergencies in a nuclear power plant. However, the time to execute an emergency procedural task is highly dependent upon expert judgment due to the lack of actual data. This paper proposes an analytical method to estimate the operator's performance time (OPT) of a procedural task, which is based on a measure of the task complexity (TACOM). The proposed method for estimating an OPT is an equation that uses the TACOM as a variable, and the OPT of a procedural task can be calculated if its relevant TACOM score is available. The validity of the proposed equation is demonstrated by comparing the estimated OPTs with the observed OPTs for emergency procedural tasks in a steam generator tube rupture scenario.

Procedural generation methods based on physical-based materials generate data by algorithms rather than manual through combinations with artist-generated assets based on computer-generated randomness algorithms. For this reason, the procedural generation method is mainly used to produce textures of 3D models in the field of computer graphics because it is easy to obtain the desired quality with little data. This study is a study on physical-based materials and procedural generation methods based on them. Physical-based materials are divided into Metallic/Roughness workflows and Specific/Glossiness workflows. These two methods produce the same results, which are more accurate based on the law of conservation of energy. The procedural generation method allows a natural texture to be obtained very quickly by texturing through a combination of a computer-generated random algorithm and an artist-generated asset based on various maps.

The purpose of this study is to verify the mediating effect of pay satisfaction on the relation between procedural justice and organizational commitment. A survey was conducted to examine the mediating effect of pay satisfaction on the responses of 529 employees. The study chose sex, age, education, position, job type and career as control variable, and the regression model which treated procedural justice as independent variable and organizational commitment as criterion variables were set. A pay satisfaction was supposed as mediating variable of these relationships. The data analysis was conducted by SAS 9.4ver and LISREL 8.80. The results of this study confirm underneath the followings. First, the relation of procedural justice and organizational commitment are significantly unique. Second, procedural justice are positively related to pay satisfaction. Third, pay satisfaction is significantly positively related to organizational commitment. Fourth, the pay satisfaction is partially mediated on the relationship between procedural justice and organizational commitment. This means that the pay satisfaction mediates the relation of procedural justice and organizational commitment. These results are different from the prior researches which had treated pay satisfaction as mediating variable of procedural justice and organizational commitment. Based on the findings of the study, this study presented managerial implications and suggestions for future studies.

The purpose of this study includes: Firstly, to examine the effects of procedural justice and job significance on value of work, psychological ownership, and job satisfaction. Secondly, to examine the mediating effect of the value of work, psychological ownership on the relationship between procedural justice, job significance and job satisfaction. For the study, the data was collected from convenient sample of 273 nurses at university hospital in a city to test theoretical model and its hypotheses. All data collected from the survey were analyzed using with SPSS 18.0 and AMOS 18.0. This study reports findings as followed: first, the relationship between the procedural justice and the value of work is positively related. Second, there was also a positive correlation between the procedural justice and the psychological ownership. Third, there was also a positive correlation between the job significance and the value of work. Fourth, the relationship between the job significance and the psychological ownership is positively related. Fifth, there was also a positive correlation between the value of work and the psychological ownership. Sixth, there was also a positive correlation between the procedural justice and the job satisfaction. Seventh, the relationship between the job significance and the job satisfaction is positively related. Eighth, there was also a positive correlation between the value of work and the job satisfaction. Ninth, there was also a positive correlation between the psychological ownership and the job satisfaction. Finally, the value of work and psychological ownership played as a partial mediator on the relationship between procedural justice and job satisfaction. Also, the value of work and psychological ownership played as a partial mediator on the relationship between job significance and job satisfaction. Based on these findings, the limitations of the study and some directions for future studies were presented.

The purpose of this study is to investigate the impacts of distributive and procedural justice on job satisfaction and organizational commitment among hospital nurses. The samples of this study consisted of 353 nurses from 8 general hospitals located in Seoul and Youngnam area in Korea. Data were collected with self-administered questionnaires and analyzed using hierarchical regression technique. Contrary to the predictions of the interaction, main effect or cultural model, the results of this study show that both distributive and procedural justice have significant positive impacts on job satisfaction and organizational commitment among hospital nurses, and the former has stronger effects than the latter. The results imply that hospital administrators should take measures to establish procedural and distributive justice to increase job satisfaction and organizational commitment among hospital nurses.

Isik & K$_1$l$_1$c (1998: Mathematics Education and its Appraising in the Primary School Teacher Certificate) found that many prospective mathematics teachers for primary schools who attended at newly established certificate programs made significant misconception on mathematics education because they were not graduates of education faculties. The levels of conceptual knowledge and procedural knowledge of students from a secondary school in Erzurum, Turkey were investigated in order to reveal how serious misconception the teachers have been made so far. The conceptual knowledge is very important to students, however in this research, it was found that procedural knowledge was much more important than conceptual knowledge.

ISO 10303-112 is an integrated application resource of ISO 10303, commonly known as STEP, and specifies the procedural_sketch schema. The ISO 10303-112 provides general resources for the representation of modeling commands for the exchange of procedurally represented 2D CAD models. Procedural models have the advantage of being easy to edit, simply by changing values of parameters of their constructional operations. Such models are said to embody design intent, in the sense that modifications to them conform to the method of creation used by their original creator, and they also comply with any constraints implied by the particular constructional operations used. This paper introduces the development and standardization process of the ISO 10303-112, and describes the concept of procedural 2D CAD modeling, the way to represent the procedural 2D CAD models in STEP and the harmonization with other STEP resources.

For elementary school children, learning the standard multiplication algorithm with accuracy, clarity, consistency, and efficiency is a daunting task. Nonetheless, what should be our expectation in procedural fluency, for example, in finding the product of 25 and 37 among fifth grade students? Collectively, has the mathematics education community emphasized the value of conceptual understanding to the detriment of procedural fluency? In addition to examining these questions, we survey multiplication algorithms throughout history and in textbooks and reconceptualize the standard multiplication algorithm by using a new tool called the Multiplication Aid Template.

Purpose: This study was performed to measure the justice of compensation (distributive justice, procedural justice) and the intention of turnover perceived by nurses, and to identify the relationship between these two variables. Method: This study was a cross-sectional survey. From May 26 to June 30, 2008, data were collected from the 300 nurses working at 6 general hospitals in 5 cities, Korea. Result: The score of compensatory justice was 2.47(distributive justice was 2.46, procedural justice was 2.48), and the score of turnover intention was 3.39. The Pearson Correlation Coefficient between these two variables was -.496. The perceived compensatory justice(distributive justice, procedural justice)by nurses, their age and working periods were the affecting factors on their turnover intention, and the power of explanation of these affecting factors was 43.4%. Conclusion: According to the results, procedural justice is the most powerful factor among these affecting factors. Therefore, it is concluded that to decrease nurses' turnover intention, nursing or hospital managers have to fairly operate their compensation system, especially procedural justice, in their organization.
