We construct a general bi-basic inverse series relation which provides extension to several q-polynomials including the Askey-Wilson polynomials and the q-Racah polynomials. We introduce a general class of polynomials suggested by this general inverse pair which would unify certain polynomials such as the q-extended Jacobi polynomials and q-Konhauser polynomials. We then emphasize on applications of the general inverse pair and obtain the generating function relations, summation formulas involving the associated polynomials and derive the p-deformation of some of the q-analogues of Riordan's classes of inverse series relations. We also illustrate the companion matrix corresponding to the general class of polynomials; this is followed by a chart showing the reducibility of the extended p-deformed Askey-Wilson polynomials as well as the extended p-deformed q-Racah polynomials.

Under recent educational and social backgrounds, alternative education schools are increasing continuously, to compare Japanese example that experience of similar circumstance given before with the investigation of general present condition, specialized education contents, facilities and utilization of 5 schools of Tokyo area, I could know following contents ; First, free schools of Tokyo area were operated by individual education type that consider each student's special quality maximum comparing with Korea's alternative schools which seek community education type. Second, there were not many schools which prescribe school personal allowance per division or class comparing with our cases that operate divides step by equal class with general school and prescribes personal allowance by class, and whole students are generally about $20{\sim}30$. Third, comparing with our cases that are located in mountain and rural area according to profitable locational conditions for environment and experience studying, it was general which islocatedin downtown for the purpose of free attending school of non attending school students. Fourth, usually, comparing with our that unused schools in mountain and rural area are general for alternative school and there were a lot of cases that uses small building of downtown such as lease office, unused warehouse and factory for free school of Tokyo area.

The purpose of this study is to find the reason why the National Mourning Dress System of the Joseon Dynasty had been established although the General Mourning Dress System had exist through research of three things; differences of each social class, changes of the National Mourning Dress System by the age and differences between the National one and the General one. The methodology which is adopted for this study is comparative analysis by social class, period and age from the Annals of the Joseon Dynasty and the Orye-e. And this study is focus on the women's dress. The results of this study is as follows; Firstly, some mourning dress items had been different or not used by class. Secondly, although there had not been a great change, some dress items had been disappeared or used irregularly. And Naemyoungbu Naekwan's mourning dress had been changed by the age. Thirdly, The National one was more extensive in wearing and applied differently by class compare to the General one. Also it had an additional rule according to the period, duty and place to Naemyoungbu-Naekwan and Naemyoungbu-Goongkwan. The National one had been established by ruling class of The Joseon Dynasty who had tried to keep the Confucian standard and perfect social status system. And it is supposed that the National Mourning Dress System had not been a great change because the ruling class' will had not been changed.

Purpose: The purpose of the study was to determine the general characteristics of students in dental technology departments; the correlations among their immersion in learning, class satisfaction, and academic achievement; factors influencing online learning experience; ways to improve students' class satisfaction; and basic data for designing effective online courses. Methods: A total of 300 questionnaires were produced and distributed to dental technology students from September 29 through October 8, 2020. The outcome was analyzed using IBM SPSS Statistics ver. 25.0. A significance level of α=0.05 was used for reliable verification. Results: Immersion in learning, class satisfaction, and academic achievement were relatively high among students who studied on a regular basis, and class satisfaction and academic achievement were relatively high among students who studied with almost no interruption. Concerning the correlations between academic achievement, immersion in learning, and class satisfaction in online learning, the correlation between academic achievement and class satisfaction was the highest at r=0.862. Class satisfaction was the largest factor that influenced academic achievement, and the higher students' immersion in learning and class satisfaction were, the higher their academic achievement was. Conclusion: The research is a case study that investigated the general characteristics of dental technology department students and the correlations among their immersion in learning, class satisfaction, and academic achievement. The study outcome could be used in determining factors that influence online learning and designing effective online courses that improve learner satisfaction.

Course evaluation serves as helpful information to improve the quality of college education and improve lectures. This study derived the factors through preceding research and FGI to explore the factors that constitute course evaluation and identified the relative importance and priority of the factors through the Analytic Hierarchy Process (AHP). For this, it derived five factors and 15 evaluation items as follows. To secure expertise and fairness in the factor development of course evaluation, the researcher conducted a questionnaire surveying students and teachers and collected a total of 20 valid data. The weight of each evaluation item was calculated based on the data that had been verified for consistency. The analysis concluded that students rated class content, class method, class operation, class evaluation, and class plan as the critical factors in the order of importance, while teachers evaluated class content, class operation, class method, class evaluation, and class plan as important, in that order. Based on the results of this study, I hope that various analyses and studies will be conducted to improve the efficiency and reliability of course evaluation for the quality management of college education.

This study analyzed the teacher's perception for influence of behavioral characteristics of scientifically-gifted students on general students in elementary school science class. To do this, we selected the eight elementary school teachers who were conducting the regular science classes including scientifically-gifted students belonging to the gifted education institutes in Seoul and conducted individual in-depth interviews. The analysis of the results reveal that the teachers mentioned seven behavioral characteristics of scientifically-gifted students in general elementary school science classes.: 'excellent in designing and performing experiments', 'playing a leading role in experiments', 'expressing their abundant prior knowledge frequently', 'attempting their tasks with curiosity and persistence', 'displaying scientific creativity', 'often asking scientific questions in detail', and 'expressing their opinions logically'. These behavioral characteristics of scientifically-gifted students had positive effects on general students, such as 'providing them with a successful experience in conducting experiments', 'improving understanding of science class contents', 'developing scientific thinking and reflective thinking', and 'improving their students' positive experiences about science'. However, the excessive learning-driven behaviors of scientifically-gifted students had negative effects on general students, such as 'limiting opportunities for general students to participate in classes', 'conducting passive exploration centered on results', and 'causing conflicts with general students'. Educational implications of these findings are discussed.

Purpose: The objective of our study was to figure out costs of nursing services in general nursing units based on the PCS in order to determine an appropriate nursing fee schedule. Method: The data were collected from 8 hospitals from September 9 to October 8, 2002. The costs of nursing services in general nursing units was analyzed by nursing hours based on the nursing intensity. The inpatient in the general nursing units were classified by Park's PCS tool(2000). Results: The distribution of patients by PCS ranged from class I to Class III in general nursing units. The higher PCS in general nursing units consumed more nursing hours. As a result, the higher nursing intensity, the more the daily average nursing costs in general nursing units. Conclusion: We found that the higher PCS, the more the daily average nursing costs in general nursing units. In conclusion, our study provides the evidence to refine the current nursing fee schedule that it does not differentiated from the volume of nursing services based on the nursing hours.

A general class of two-point optimal fourth-order methods is proposed for locating multiple roots of a nonlinear equation. We investigate convergence analysis and computational properties for the family. Special and simple cases are considered for real-life applications. Numerical experiments strongly verify the convergence behavior and the developed theory.

This paper extends the existence proofs of a Nash equilibrium to a more general class of differentila game models with constraints on the control spaces. With the assumptions of continuity, convexity, and compactness, the existence is proved using Kakutani Theorem and via a path-following approach. Furthermore, the proof for a period-by-period optimization of multi-period problems provides an insight to a numerical solution algorithm to differential game models with constraints.
