Purpose: The concept of the Barrier-Free Design has steadily expanded into a basic principle of design, which can provide safe and convenient lives not only limited to the disables, elders, and pregnant women, but also to all members of the society. This is what we now know as the Universal Design. In other words, Barrier-Free Design for all is Architectural Approach of Universal Design. Thus, as a future-oriented alternative to school facilities according to social change, this study suggests basic direction of school building planning and concept of universal design considering school facilities characteristics. Methods: The characteristics of school facilities are understood from the perspective of Universal Design. In addition, a survey is conducted to identify the current state of school facilities. Result: Findings from this study are as follows. First, Universal Design of School Building is an integrated characteristic. Integration is intended to create and manage an integrated environment instead of an individual and one-time approach to installation and maintenance of convenience facilities. Second, It is a flexible characteristic to be sustainable. In other words, they aim to be selectable to respond to change. Third, It is a characteristic of accumulation of outstanding cases. This means that not only individual schools but also entire school spaces will be applied to Universal Design to form a virtuous circle of environment improvement. Implications: The results of this study may serve as a basic concept in the design of school buildings.

In this paper, we propose a method to detect concept drift by applying Convolutional Neural Network (CNN) in a data stream environment. Since the conventional method compares only the final output value of the CNN and detects it as a concept drift if there is a difference, there is a problem in that the actual input value of the data stream reacts sensitively even if there is no significant difference and is incorrectly detected as a concept drift. Therefore, in this paper, in order to reduce such errors, not only the output value of CNN but also the probability vector are used. First, the data entered into the data stream is patterned to learn from the neural network model, and the difference between the output value and probability vector of the current data and the historical data of these learned neural network models is compared to detect the concept drift. The proposed method confirmed that only CNN output values could be used to reduce detection errors compared to how concept drift were detected.

The IEEE std 738 and Cigre Electra documents are well known as the standard of calculating the ampacity of overhead conductors. Although these two standards use the same basic heat balance concept, they use different applicable methods to calculate ampacity ratings. This paper examines the concept of basic heat balance equation and the differences of each term of basic heat balance equation.

In order to educate future leaders of the new age, we should help students to increase their basic knowledge, thinking and problem solving ability. It is necessary that we should use multi-media, computer as well as old teaching-learning material to improve students' basic knowledge and to motivate their interest in mathematics in the small-sized Middle School situated on the agricultural and fishery village. In solving this problem, it is ultimately necessary that we should utilize CAI program on the learning achievement in mathematics for the students to understand basic concept, principle, law and to promote teaching-learning process considered on individual different abilities. Therefore, this study is on the effect of students' interest and learning achievement in mathematics when we develop CAI program focusing on the lesson statistics in the 3rd Grade Middle School Mathematics Textbook and explain the concept and principle of statistics through using exact and various techniques of computers

Purpose. The aim of this study was to provide Aromatherapist with analysis of the effect of natural aroma essential oil on middle school students' self-concept. Methods. In total, 20 students were recruited to answer a self-administered questionnaire in pre and post. The questionnaire was composed of questions about general self-concept, class self-concept, achievement self-concept, ability self-concept, social self-concept, family self-concept, emotional self-concept, physical self-concept. The natural aroma essential oil program was operational in a 90-minute once a week for ten weeks. Results. As a result, the score of emotional self-concept(t=-2.60, p<.05) is higher than pre the experiment post experiment. Conclusions. This study is to get a basic data of natural aroma should be applied to improve self-concept of middle school students.

Number concept is basic in mathematics education. But it is very complex and is not easy to understand real number concept, because of its infinity. This study tried to show that what percents of secondary school mathematics teachers in Korea understood the properties of real number, such as cardinality, continuity, relation with real line, and infinity, which were written by verbal language.

초등학교 수학에서 지도하는 기하 내용 중 중요한 것 중의 하나가 도형을 시각적인 외양만을 가지고 바라보는 것이 아니라 도형의 구성요소와 성질을 가지고 파악하도록 지도하는 것이다. 따라서 본 연구에서는 초등학교에서 평행과 평행선에 관한 고찰하여 보았다. 학생들이 평행선에 관하여 잘못된 개념 이미지를 갖게 된 이유 중의 하나가 교과서에 제시된 예들로 보이며, 두 직선이나 선분이 평행한지 여부를 판단하는 방법에 대한 지도가 미흡하며, 이를 개선하기 위해서는 두 선분이나 직선이 평행한지를 판단하는 방법이 필요하며, 특히 초등학교 수학에서는 모눈종이 위에 그려진 두 직선의 평행여부를 판단하는 방법을 지도하는 것이 필수적으로 필요함을 살펴보았다. 이를 바탕으로 두 직선이나 선분이 평행한지 여부를 판단하는 방법을 지도하는 구체적인 방안을 제시하였다.

Vibrations at different frequencies with a different intensity as well as a pressure pulsation with different parameters are two phenomena which can be observed at different water turbines. Due to the vibration and the pressure pulsation some restrictions of water turbine operation range are applied. Similar problems with the efficiency level in a wide water turbine operation range are the basic problems which are solved for ages. A theoretical and practical solution of the above mentioned problems is very much time and money consuming. The paper describes a new theoretical solution of the excitation and pressure pulsation decrease as well as extension of the operational range with high efficiency level. The new concept to decrease the vibrations and pressure pulsations is based on a heterogeneous runner blade geometry generation. The new concept of the runner geometry design was numerically tested at a low specific speed pump turbine, see Fig. 1, and basic points of the concept are presented in this paper.
