Any Hausdoroff space on a set which has at least two points a regular closed Boolean algebra different from the indiscrete regular closed Boolean algebra as indiscrete space. The Sierpinski space and the space with finite complement topology on any infinite set etc. do the same. However, there is $T_{0}$ space which does the same with Hausdorpff space as above. The regular closed Boolean algebra in a topological space is isomorphic to that algebra in the space with its open extension topology.

A definition of finite automaton (DFA and NDFA) with intuitionistic fuzzy (final) states is proposed. Acceptance of intuitionistic fuzzy regular language by the finite automaton (DFA and NDFA) with intuitionistic fuzzy (final) states are examined. It is found that the finite automaton (DFA and NDFA) with intuitionistic fuzzy (final) states is more suitable for recognizing intuitionistic fuzzy regular language than earlier model. The paper also gives an idea of intuitionistic fuzzy regular expressions through possible definitions.

A ring $R$ is called semiregular if $R/J$ is regular and idem-potents lift modulo $J$, where $J$ denotes the Jacobson radical of $R$. We give some characterizations of rings $R$ such that idempotents lift modulo $J$, and $R/J$ satisfies one of the following conditions: (one-sided) unit-regular, strongly regular, (unit, strongly, weakly) ${\pi}$-regular.

We will construct several types of semi-regular tilings of a hyperbolic unit disk model by defining geometric features of the definition of distance in a hyperbolic plane, area of triangle, and isometry of inversions. We researched the method of regular tilings and semi-regular tilings of hyperbolic unit disk model and wrote an semi-regular tiling construction algorithm using Cabri2 program and Cinderella program. Lastly, We want to make a product related to traditional heritage cultural patterns using Photoshop, so we'll model the advertising photos of cites; Seoul, Gwangju.

We consider the ordered ${\Gamma}$-semigroups in which $x{\gamma}x(x{\in}M,{\gamma}{\in}{\Gamma})$ are left elements. We show that this $po-{\Gamma}$-semigroup is left regular if and only if M is a union of left simple sub-${\Gamma}$-semigroups of M.

The paper refers to ordered semigroups in which $x^2 (x \in S)$ are left ideal elements. We mainly show that this $po$-semigroup is left regular if and only if S is a union of left simple subsemigroups of S.

The purpose of this study was to investigate the of regular worksite health exercise program participation on related fitness. Subject for study were 34 middle-aged women in Kwangju-city. To achieve this, body composition, cardiopulmonary function, physical fitness of every subjects were measured before and post regular health exercise program participation during 12 week. The results of this study were as follows: 1. Regular health exercise program participation result from improving the body composition, but there is not significant different statistically(p〈.05). 2. Significant differences were observed in the cardiopulmonary function(vital capacity, VO$_2$ max) after regular exercise program during 12 week(p〈.05). 3. Significant differences were observed in the flexibility(sitting trunk flexion), abdominal endurance(sit-ups), power (standing high jump), agility(trunk reaction time) after regular exercise program during 12 week(p〈.05).

본 연구는 유아교육기관에서 정교사 2인 공동담임제의 현실적인 탐색을 통해 현장적용을 실천하는데 도움이 되고 이를 통해 전문성을 갖춘 교사체제를 정립함으로써 교사간의 협력적인 능력 창출과 운영에 대한 기초연구가 되고자 한다. 이를 위해 2017년 4월부터 7월까지 약 3개월간 경기도 소재의 K유치원에서 교사 16을 대상으로 반구조화 된 개인 및 집단면담 13회, 현장관찰 8회, 참여관찰 4회에 걸쳐 수집한 자료를 분석하였다. 자료의 분석은 질적 자료 분석 방법인 키워드 분류, 유목화, 소주제 발견 단계로 진행 되었다. 그 결과, 정교사 2인 공동담임제의 협력적 운영에 대해 '업무 수행', '어려움', '기관의 지원', '변화'로 범주화하여 기술하였다. 이러한 연구결과를 통해, 정교사 2인 공동담임제를 도입하여 전문성을 갖춘 2인 교사가 협력적 운영의 과정, 변화를 통해 교육의 질을 향상시키는 데 기반이 될 것으로 기대한다.

영재학생에게 적합한 세분화 교육의 방안을 모색하기 위하여 학교, 학원, 영재원에서 이루어지는 과학 수업에서의 세분화 현황을 파악하였다. 서울 지역의 특정 대학부설 영재교육원에서 교육을 받는 중학교 2학년 학생 90명이 세분화 경험을 묻는 설문지에 응답하였으며 문항별, 장소별로 교차 분석한 결과는 다음과 같이 나타났다. 영재원에서는 다양한 자료를 활용하여 수업 받은 경험 있는 반면 학교에서는 주로 교과서를, 학원에서는 자습서를 활용하여 수업을 받고 있었다. 또한 학교나 학원에서 형성평가를 자주 치르는 것으로 나타났으며, 학습 속도가 빠른 학생들이 학습과 관련 없는 활동이나 복습 및 문제풀이에 시간을 보내고 있었다. 영재학생들은 주로 학교 과학 수업을 통해 스스로 흥미를 탐색하는 경향이 나타났지만 흥미를 바탕으로 집단을 구성하는 노력은 영재원에서 우세하게 나타났다. 학습 활동에 대한 학생의 선택과 수업 내용을 미리 익힌 학생을 위한 교사의 준비에 대한 응답률은 가장 낮게 나타났다.

Notwithstanding Korea and P. R.China are located in the neighborhood each other geographically, the break of diplomatic relations of them continued a long term, and the difference of ideology and social structure of two countries was acting as a barrier to understand each other in many fields. Two countries established formal diplomatic relation in 1992, and then the interchange and mutual cooperation between both countries are being performed rapidly, but the field of fisheries education and research system is continuing in the early stage yet. It can be easily expected that the interchange and mutual cooperation in the field of fisheries through the ocean contribute not only to the international friendship, but to the rational management of fisheries resources. In accordence with the necessity mentioned above, the author considered the general situation of fisheries education and research system in P. R. China. P. R. China runs two kinds of fisheries education system which are regular and irregular system. The regular education system is the principal means of cultivating fisheries scientists and technicians. And there are three grade levels in regular education : the tasks of which are undertaken by the fisheries universities, fisheries colleges and fisheries high schools. Adult education system in fisheries are of the following types : fishery cadet training courses, evening schools, correspondence courses and broadcasting or TV programs. The fisheries research in P. R. China is undertaken by the research institutes under the Bureau of Aquatic Products, and the basic research of oceanography is undertaken by the oceanographic institutes under the Chinese Academy of Science.
