This paper is to find out a possibility that, adapting article 81 of regional finacing law, the community develops community facilities such as gymnagiums, swimming pools, and parking facilities in school site. The study requires an agreement about managements between the mayor and the superintendent of education. This paper also surveys community's needs with respect to use of school facilities before and after class, willingness to pay for the school use, and use of school facilities by private institutions. This paper adopts two experimental case studies to find a feasibility of community building construction in school sites. It also adopts dscriptive analysis of the statistics to find out the degree of willingness to use by community people. It is found, first, that regional finacing law permits community facilities' development in school sites and an agreement between the mayor and the superintendent of education about usage and profits should be made by the rate of construction fee and land cost. The second is that 65.8% of community people want to use school facilities such as gymnasium and school ground. And favorite series of physical exercise is swimming, baminton, tennis in order. The third is that 66.4% of community people have willingness to pay for the use of school facilities. The fourth is that school facilities such as class room, special class room, and computer room can be used by private institutions. 75% of community people agree to use school facilities by the private institutions. Favorite series on these are classes for reviewing the lessons, language classes, classes for playing musical instruments in order.

In this paper, we investigate the $\mathbb{R}$-complex Hermitian Finsler spaces, emphasizing the differences that separate them from the complex Finsler spaces. The tools used in this study are the Chern-Finsler and Berwald connections. By means of these connections, some classes of the $\mathbb{R}$-complex Hermitian Finsler spaces are defined, (e.g. weakly K$\ddot{a}$hler, K$\ddot{a}$hler, strongly K$\ddot{a}$hler). Here the notions of K$\ddot{a}$hler and strongly K$\ddot{a}$hler do not coincide, unlike the complex Finsler case. Also, some kinds of Berwald notions for such spaces are introduced. A special approach is devoted to obtain the equivalence conditions for an $\mathbb{R}$-complex Hermitian Finsler space to become a weakly Berwald or Berwald. Finally, we obtain the conditions under which an $\mathbb{R}$-complex Hermitian Finsler space with Randers metric is Berwald. We get some clear examples which illustrate the interest for this work.

Several different classes of antidepressants(ADs) with newer drugs becoming available have been used for the phamacological management of a broad spectrum of mental disorders, among which depressive disorder is most commonly indicated. Successful clinical use of ADs requires a complete understanding of the psychopharmacological properties of ADs and on accurate knowledge of patients, characteristics based on clinical experience and theoretical framework. This paper aims at providing some practical information on the clinical use of ADs to assist clinicians in treating patients with major depression. The author describes (1) different classes of ADs and their presumed mechanisms of action, (2) clinical characteristics of ADs focusing on side-effect profiles, (3) some issues arising during the treatment course such as : a) pretreatment tasks, b) choice of ADs, c) therapeutic drug dose and monitoring of drug concentration, d) three stages of treatment and e) strategies in refractory depression and (4) ADs in special patient groups.

We consider $M_1,M_2/M/1$ retrial queues with two classes of customers in which the service rates depend on the total number or the customers served since the beginning of the current busy period. In the case that arriving customers are bloced due to the channel being busy, the class 1 customers are queued in the priority group and are served as soon as the channel is free, whereas the class 2 customers enter the retrical group in order to try service again after a random amount of time. For the first $N(N \geq 1)$ exceptional services model which is a special case of our model, we derive the joint generating function of the numbers of customers in the two groups. When N = 1 i.e., the first exceptional service model, we obtain the joint generating function explicitly and if the arrival rate of class 2 customers is 0, we show that the results for our model coincide with known results for the M/M/1 queues with smart machine.

In this paper, we introduce and explore suggested notions of 'above', 'below' and 'between' in general groupoids, Bin(X), as well as in more detail in several well-known classes of groupoids, including groups, semigroups, selective groupoids (digraphs), d/BCK-algebras, linear groupoids over fields and special cases, in order to illustrate the usefulness of these ideas. Additionally, for groupoid-classes (e.g., BCK-algebras) where these notions have already been accepted in a standard form, we look at connections between the several definitions which result from our introduction of these ideas as presented in this paper.

The classes of Reverse Jacket matrix [RJ]$_{N}$ and the corresponding Restclass Reverse Jacket matrix ([RRJ]$_{N}$) are defined;the main property of [RJ]$_{N}$ is that the inverse matrices of them can be obtained very easily and have a special structure. [RJ]$_{N}$ is derived from the weighted hadamard Transform corresponding to hadamard matrix [H]$_{N}$ and a basic symmertric matrix D. the classes of [RJ]$_{2}$ can be used as a generalize Quincunx subsampling matrix and serveral polygonal subsampling matrices. In this paper, we will present in particular the systematical block-wise extending-method for {RJ]$_{N}$. We have deduced a new orthorgonal matrix $M_{1}$.mem.[RRJ]$_{N}$ from a nonorthogonal matrix $M_{O}$.mem.[RJ]$_{N}$. These matrices can be used to develop efficient algorithms in IMT2000 signal processing, multidimensional subsampling, spectrum analyzers, and signal screamblers, as well as in speech and image signal processing.gnal processing.g.

The main purpose of this study is to examine housing norm of the middle classes, housing norm and normative housing deficits by independent variables(socio - economic variables, family characteristic variable sand housing characteristic variables).There are two major findings of this study as follows :1. In the housing norm, housing space is 99.Om2, the number of rooms is 3.0, housing structure type is apartment, the maintenance cost is 13 thousand won, and housing tenure is home ownership. And housing qualify is classified into 5 dimensions, and neighborhood environment is classified into 3 dimensions.2. This thesis is to conform Morris et aL.(1984)`s hypotheses that cultural norm is homogeneous in culturally unified society and if it appears heterogeneously, It is the subject`s reporting error of the subjects confusing cultural norm with family norm.

The characteristic aspects of learning a foreign language require special resources and tools for online learning. Criteria for choosing educational platforms depend on key elements of an academic subject area. Microsoft Teams (hereafter, MT) educational platform is competitive one because it meets most of the needs that arise during the formation of a secondary linguistic persona. Due to the large number of corporate programs, there are a successful acquisition of language skills and the implementation of all types of oral activities of students. A significant MT advantage is the constant analysis and monitoring of the platform of participants' needs in the educational process by developers. The article highlights MT advantages and disadvantages. The attention is drawn to individual programs, which, in the authors' opinion, are the most successful to learn writing, reading, speaking, listening, as well as organize classes that meet needs of modern foreign students.

The purpose of this study was to analyze the cases of verbal interactions occurring during the mathematics lessons taught in middle school special classes in order to examine the elements and types of verbal interactions that occur between the teachers and students. Data were collected and analyzed for the sessions on geometric units that formed part of the mathematics lessons routinely implemented in the special classes. The analysis showed that the teachers initiated 237 (84.1%) of the 291 instances of verbal linguistic interactions. A total of 240 teachers' questions were analyzed, and questions in the area of knowledge occurred the most frequently, at 160 times (66.7%). A total of 617 student responses were analyzed, and short answers occurred the most frequently, at 367 times (59.5%). Teacher feedback occurred 581 times in total, and correct/incorrect (simple) feedback occurred the most frequently, at 234 times (40.3%). A total of 237 verbal interactions were observed between the teachers and children, and the I (RF) type (one teacher question, one student response, and one instance of teacher feedback) occurred most frequently, at 83 times (35.0%).

Special skills and aptitude education which cultivates special skills and aptitude of students in widely implemented in elementary schools as a part of extracurricular activities after classes. This research is designed to find out improved operations in elementary schools' special skills and aptitude education activities by examining and analyzing the current situation. A survey of teachers and students was conducted on the teachers' interests in the special skills and aptitude education as well as on the participation level of students. In order to systematically operate and to vitalize the special skills and aptitude education, there should be full support and continuous interest from the Ministry of Education. In addition, hosting school's interests such as interlinking with other schools and attending exhibitions are important to maximize the effect of student's computer skills and aptitude education.
