This study was performed to verify the validity and utility of the Korean Behavior Rating Inventory of Executive Function-Preschool Version(BRIEF-P). The BRIEF-P is one of the most used instruments to measure Executive Function(EF) and a teacher-rating assessment method designed to measure the executive function of preschoolers(age 2-5). A total of 200 preschoolers(104 boys, 96 girls; recruited aged 3 to 5years) participated. Confirmatory factor analysis was carried out to evaluate the model structure. Correlation analysis was done to verify the concurrent validity. In the results, the model fit indexes were good with the five BRIEF-P subscales (that is, inhibit, shift, emotional control, working memory, plan/organize). The internal consistency of the BRIEF-P five subscales were supported. As a results, the Korean Behavior Rating Inventory of Executive Function-Preschool Version(BRIEF-P) was confirmed to be a reliable and valid assessment tool to measure executive function in preschoolers.

Electrical safety monitoring System (ESMS) is a critical component in modern power systems, which is characterized by large-scale access points, massive users and versatile requirements. For convenience of the information integration and analysis, the software development, maintenance, and application in the system, the cloud platform based ESMS is established and assessed in this paper. Firstly the framework of the system is proposed, and then the assessment scheme with a set of evaluation indices are presented, by which the appropriate cloud product can be chosen to meet the requirements of a specific application. Moreover, to calculate the weights of the evaluation indices under uncertainty, an improved interval AHP method is adopted to take into consideration of the fuzziness of expert scoring, the qualitative consistency test, and the two normalizations in the process of eigenvectors. Case studies have been made to verify the feasibility of the assessment approach for ESMS.

Purpose: Infant regurgitation is associated with other functional gastrointestinal disorders and signs and symptoms that have a major impact on the quality of life of infants and their families. This study evaluated the safety, tolerance, and real-world effectiveness of an anti-regurgitation formula containing locust bean gum (LBG), prebiotics, and postbiotics to alleviate digestive symptoms beyond regurgitation. Methods: This 3-month study involved infants with regurgitation requiring the prescription of an anti-regurgitation formula according to usual clinical practice. Outcomes included evaluation of the evolution of stool consistency and frequency; occurrence of colic, constipation, and diarrhea; and assessment of regurgitation severity. Infant crying, parental assessment of infant well-being, and parental satisfaction with the stool consistency were also evaluated. Results: In total, 190 infants (average age: 1.9±1.1 months) were included. After three months, stool frequency and consistency remained within the normal physiological range, with 82.7% of infants passing one or two stools per day and 90.4% passing loose or formed stools. There was no significant increase in the number of infants with diarrhea, whereas a decrease was observed in the number of infants with constipation after 1 month (p=0.001) and with colic after both 1 and 3 months (p<0.001). Regurgitation severity and crying decreased and parental satisfaction with stool consistency, formula acceptability, infant well-being, and sleep quality increased. Monitoring of adverse events did not reveal any safety concerns. Conclusion: Formulas containing LBG, prebiotics, and postbiotics were well tolerated and provided an effective strategy for managing infant regurgitation and gastrointestinal discomfort.

Objectives The Yin-Yang construct was shown to have stable internal reliability or consistency using Sasang Personality Questionnaire (SPQ) throughout the various ages, however the study of stability over specific period of time was only conducted using adults. The purpose of the study was to examine the stability across the time using middle school students whose physical and psychological characteristics were most rapidly changing. Methods The 122 middle school students (65 boys and 57 girls) completed the SPQ at 1st year and 2nd year with one-year time difference. Cronbach's ${\alpha}$ and Pearson's correlation analysis were employed in order to show the internal consistency and stability over one-year interval after considering sex difference. Results The internal consistency of SPQ-T, SPQ-B, SPQ-C, SPQ-E using Cronbach's ${\alpha}$ were .61, .72, .28, .28 in 2016 and .62, .72, .26, .46 in 2017. The one-year test-retest reliability of SPQ-T, SPQ-B, SPQ-C, SPQ-E using Pearson's correlation analysis were .56, .61, .31, .23 in boys and .58, .63, .64, .29 in girls. Conclusion The current study showed the stability of Yin-Yang temperament across the one-year time suggesting that the Yin-Yang temperament is quite stable and measurable concept and the SPQ would be considered as an objective and reliable personality assessment.

The basic structure for assessment of potential health risks from environmental chemicals is widely agreed upon, but many of the details of risk assessment procedures differ among practitioners. Government regulatory agencies typically have guidelines or standard procedures for their risk assessments, established to ensure consistency and comparability, to set standards for adequacy, and to embody underlying tenets. In setting and updating such guidelines, each agency takes into account not only the prevailing thinking about appropriate procedures, but also its own goals and responsibilities and the precedents it has set for itself in past analyses. This results in variations in methods, and consequently in characterization of risks, among regulatory assessments, even when they are based on the same data. As a result, adopting existing assessments from a variety of regulatory bodies needs to be done with caution. This paper examines some of the variants in risk assessment approaches among American federal regulatory agencies and relates them to the variations in regulatory responsibilities of those groups. Comparisons to international practices are also drawn. The impact on development of world-wide risk standards is discussed.
