This study was conducted to provide basic data for prioritization of family support services by examining the importance and performance of family support for parents of children with special education. To achieve the purpose of the study, a questionnaire survey was conducted with 220 parents of children from special education nationwide. As a result of the study, the importance of all 29 family support service items was rated high, but the performance level was low, and statistically significant differences were found. In addition, as a result of analysis of importance and performance, family support services related to physical and physical well-being and disability-related support were evaluated as high-priority, low-practice services, and it was a task that should be presented as a priority in family support services. On the other hand, it was found that family support services in the areas of family interaction support or emotional well-being were considered to be services that should be avoided due to their low importance but high performance. Based on the results of these studies, the direction for the operation of family support services for children with special education needs to be suggested in the future.

Production planning is one of the most important activities in shipbuilding enterprises. Shop-floor supervisors and planners still do not have enough information to effectively analyze shop operations because of the difference between production planning and shop-floor scheduling. In this paper, process analysis was conducted between production planning and shop-floor control to clarify the difference, and the necessity of the manufacturing execution system(MES) was derived in a shipyard. Therefore, the simulation-based ship production execution system(SPEXS) was defined by analyzing characteristics of MES. The architectural functions of the system were deducted from the process of requirement analysis. The SPEXS' framework was constructed on the basis of the architectural functions. This framework will provide more reliable production schedules and allow engineers to plan and control shop operations in real-time.

The Java programming language is designed for developing effective applications in a heterogeneous network environment. Major problem in Java is its performance. many attractive features of Java make the development of software easy, but also make it expensive to support ; applications written in Java are often much slower than their counterparts written in C or C++. To use Java`s attractive features without the performance penalty, sophisticated optimizations and runtime systems are required. Optimising Java bytecode has several advantages. First, the bytecode is independent of any compiler that is used to generate it. Second, the bytecode optimization can be performed as a pre=pass to Just-In-Time(JIT) compilation. Many attractive features of Java make the development of software easy, but also make it expensive to support. The goal of this work is to develop automatic construction of code optimizer for Java bytecode. We`ve designed and implemented a Bytecode Optimizer that performs the peephole optimization, bytecode-specific optimization, and method-inlining techniques. Using the Classfile optimizer, we see up to 9% improvement in speed and about 20% size reduction in Java class files, when compared to average code using the interpreter alone.

This study was conducted to evaluate the association between knowledge of Coronavirus disease 2019 (COVID-19), perception of infection control and practice of infection control among dental hygienists. The questionnaires consisted of 9 demographic questions, 10 questions about COVID-19 knowledge, and 36 questions about perception and practice of infection control. The study analyzed 120 participants' data gathered from May 1 to May 31, 2021. For data analysis, T-test, ANOVA, and Pearson correlation were used. As a result, COVID-19 knowledge was 6.59 out of 10, the perception of infection control was 3.57 out of 4 and the practice of infection control was 3.55 out of 4. The COVID-19 knowledge(r=0.485) and perception of infection control(r=0.614) were significantly positively related to practice of infection control. To improve the practice of infection control in the dental field, education of infection control should be mandatory for dental hygienists. Also, the practice of infection control following "Dental Infection Control Standard Policy & Procedure" must be mandatory.

The formal specification methods with probability have been demanded in the area of fault real-time systems, in order to specify the uncertainty that the systems can encounter during their execution due to various environmental factors. This paper presents a new formal method with probability. namely Probabilistic Abstract Timed Machine (PATM), in order to analyze and predict system's behavior in dynamical environmental changes, This method classifies the factors into two classes: the variable and the constant. The analysis of system's behavior is performed on the probabilistic reachability graph generated from the ATM specification for the system. The analysis can predict any possibility that the behavior may not satisfy some safety requirements of the system, indicate which variable factors cause such satisfaction, and further recover from this unsatisfying fault state by fixing the variable factors. Consequently the reliability to the fault real-time systems can be improved.

This study analyzed the impact on entrepreneurship, passion, and start-up execution willingness to start a business for 200 prospective start-ups in Jeollanam-do. As a result of this study, it was found that there was an effect at the statistically significant level (p<.05) in the relationship between the start-up support program and start-up willingness. In the mediating effect analysis of passion for entrepreneurship support programs, it was confirmed that passion played a complete mediating role in the relationship between mentoring and start-up willingness and a partial mediating role in the relationship between the start-up support fund and start-up willingness. In the analysis of the mediating effect of passion on entrepreneurship, it was confirmed that passion played a partial mediating role in the relationship between initiative and start-up execution willingness, and also in the relationship between risk sensitivity and start-up execution willingness. This shows that when proper initiative and risk tolerance are recognized, passion enhances the start-up willingness to run into the start-up market. Based on these results, we suggested theoretical implications and policy support directions to increase the willingness of prospective founders to implement.
