  • Computational Geometry is concerned with the design and analysis of computational algorithms which solve geometry problems. Geometry problems have a large number of applications areas such as pattern recognition, image processing, computer graphics, VLSI design and statistics since they involve inherently geometric problems for which efficient algorithms have to be developed. Several parallel algorithms, based on various parallel computation models, have been proposed for solving geometric problems. We review the current status of the parallel algorithms in computational geometry.

  • Purpose: As the Act on Punishment of Serious Accidents came into effect in January 2022, it is becoming a big social issue in the labor and management circles. The purpose of this law is to analyze problems and suggest improvement plans so that the purpose of protecting lives and bodies by preventing major accidents can be met. Method: The main contents of the relevant law were identified, and the current application status of the currently enforced law and problems by law were analyzed. Result: Currently, more than 50 accidents have occurred and they have been classified as serious accidents, and no punishment has been imposed under the relevant laws. There are four major problems: 1) the issue of equity in the applied workplace, 2) the lack of clarity in some legal provisions, 3) the issue of entrusting the obligation to secure safety and health to private organizations, and 4) the issue of excessive punishment regulations. was analyzed as. Conclusion: As the law is in the early stages of enforcement, there are trials and errors, but revisions are necessary through the efforts of the labor and management circles to meet the establishment and purpose of the law.

  • Background: Cigarette smokers have their own motivation and justification to smoke. For example, smoking reduces their stress or enhances their pleasure. This study aimed to identify the (a) prevalence of cigarette smokers among undergraduates in Malaysia, (b) gender differences in nicotine dependence among current smokers, (c) differences in psychological problems (depression, anxiety and stress) based on the status of smoking cigarettes (current, former and non-smokers) and (d) extent to which precipitating factors (tension reduction, addiction, automatism, handling, social interaction, pleasure, and stimulation) predict the smoking behavior among current smokers. Materials and Methods: In this study 780 undergraduate students participated from a private university in Kuala Lumpur and Selangor state in Malaysia. The Depression, Stress and Anxiety Scale, Modified Reason for Smoking Scale and Fagerstrom Nicotine Dependence Test were used to measure psychological problems, predictors of smoking behavior and nicotine dependency among current smokers. Results: The results showed that 14.7%(n=106) of the students were smokers. Current smokers exhibited more psychological problems (depression, anxiety and stress) compared to former and non-smokers. Addiction, tension reduction, pleasure and automatism were predictors of smoking behavior among the current smoking students. Step wise regression analysis showed that smoking behavior was highly predicted by nicotine dependency or addiction. Smoking students were motivated to smoke cigarettes as they believed that it reduced their tension and enhance pleasure. Conclusions: Hence, there is a need for health promotion and anti-tobacco prevention as cigarette smokers experience more psychological problems. Nicotine dependency or addition was one of the major causes for smoking behavior among the student population in Malaysia.

  • The purpose of this study is to examine the management status of domestic presidential SNS records and to propose a management plan. Thus, the researchers examined cases of SNS records management in foreign countries, interviewed records officers in Presidential Archives, as well as conducted a status analysis of the presidential SNS records management status and the SNS accounts of former and current presidents. Based on the analysis, the current state of the domestic and international situations was analyzed. The researchers subsequently interviewed the staff in charge and found out what the problems in the current presidential SNS records management were. To solve the problems reflecting the characteristics of SNS records, a collection, management, and service plan was thus proposed. This study is meaningful in that it tried to discuss the management of the presidential SNS records and could be used as basic research of presidential SNS records.

  • In this paper are reviewed the current status of nuclear fuel management and reactor operational aid tools. In addition, we indicate deficiencies in current capabilities and what future research is judged warranted. For the nuclear fuel management review the focus is on light water reactors and the utilization of stochastic optimization methods applied to the lattice, fuel bundle, core loading pattern, and for BWRs the control rod pattern/core flow design decision making problems. Significant progress in addressing separately each of these design problems on a single cycle basis is noted; however, the outstanding challenge of addressing the integrated design problem over multiple cycles under conditions of uncertainty remains to be addressed. For the reactor operational aid tools review the focus is on core simulators, used to both process core instrumentation signals and as an operator aid to predict future core behaviors under various operational strategies. After briefly reviewing the current status of capabilities, a more in depth review of adaptive core simulation capabilities, where core simulator input data are adjusted within their known uncertainties to improved agreement between prediction and measurement, is presented. This is done in support of the belief that further development of adaptive core simulation capabilities is required to further significantly advance the utility of core simulators in support of reactor operational aid tools.
