It is necessary for lower grade students to study the correct usage of tools as a base of the technical education for dismantling and assembling various machines. However, enough understanding has not been obtained though the usage of these tools when training first grade students. So, we started to develop a teaching text and materials within the students' practice curriculum based on the dismantling and assembly of all-terrain vehicle [ATV]'s, which is a very motivating for lower grade students. This practice makes the student learn both how to use the tools and the steering mechanism of cars through the dismantling and assembling of the ATV. It is possible to not only have the student learn about the knowledge obtained through the practice, but also they also acquire wider and deeper knowledge through making the text and teaching materials for the practice. The textbook and secondary educational materials of this practice curriculum were created in cooperation with a fifth grade student as part of their graduation research. As a result, an effective teaching and learning text and secondary educational material regarding manufacturing practice could be developed from the student's point of view. Making a teaching text and materials is effective for promoting the study and experience of engineering.

This is on the dance costume of ancient Greece. The present study classified the characteristics of Greek dance and dance costume according to the silhouette, quality of material, color and ornaments. Materials of the study are the pictures and figures presented in literatures, sculptures, crockeries, murals, coins. The dances of Greece can be classified into religious dance, educational dance, recreational dance, dramatic dance and various forms of dance on each dances were developed. Especially, it is the greatest character that Greeks gave dances educational value and created composit art including song, lines and dance. As dance costume, Himation, Chiton, Chlamys which Greeks generally wore were widely worn. Also, the beauty of dance costume was maximized by the changes of basic costumes and development of various ways of wearing. Especially, professional dancers wore costumes shorter than knee-length ones forming a A-line silhouette different from a cylindrical one. Thin cloth revealing body silhouette such as fiax hemp, linen, silk were used as materials of dance costumes. As for colors, white was mainly used, But orange, blue and green were used, too. They wore band, scarf, bonnet on the head and seldom used any ornaments except for fibula. They wore the same sandals which Greeks wore, Crepis, front-heeled shoes which is thought to be the origin of modern ballet shoes for the technique of toe in dance. As mentioned above, as the dance costume of Greece were mainly worn as the similar forms of the dance costume of Greeks, various forms of costumes were worn with the development of dance and bold ways of wearing and silhouette were developed unlike the costume of common people.

The school library plays an important role to improve the student's mental activity and cultivate the formation of character and emotion. Especially in the information society, the students must collect, select and utilize the necessary information themselves. The school library has to collect, put in order and keep the book, audiovisual material and necessary information beyond it about the entire education and to offer the students and teachers them for the general school education. The school library has to be a center of school education and drive forwards the spontaneous and subjective learning activity as well as progress the education process. The school library must be the place to preserve the student's subjective study ability, that is, consolidate the materials as the study center and be composed of proper study materials for the solving-problem and research. Also to be perfect in the role of the information center, the school library has to be consolidated in accordance with development of various information softwares and ways including the newspaper, magazine, video, CD, laser disk and computer.

Outcome-Based education (OBE) is reviewed from the institutional perspective. The demand for and international trends in OBE are briefly examined and several term related to OBE, especially educational objective and program outcomes (POs), are introduced. It is stressed that systems for continuous quality improvement and quality assurance should be established to ensure the maintenance of the OBE system. Because the criteria for accreditation contain a criterion regarding the quality assurance related to program outcomes, several critical issues are considered regarding the POs themselves and the reduction of the POs. The core value of OBE is not only to provide appropriate education services to students to prepare them with the minimum skills and abilities for advancing their professional service, but also to guarantee the quality of graduates. In addition, the educational program should be continuously improved by employing the evaluation results acquired during the operation of the OBE systems. It is certain that an OBE system is one important aspect of student-centered education.

Any place where exercise is common, such as a club, sports hall, or school, is considered a place for teaching sports. When doing sports, a very safe environment for sports should be chosen. The athlete should consider the safety of sports facilities and equipment, and if there is a defect, he should refrain from exercising in these places. The safety of sports facilities is very effective in creating people's sports activities, with the benefits of staying away from physical harm, enjoying sports, and having mental peace. Everyone has the right to participate in sports and recreation and to ensure that they enjoy a safe environment. The ability to manage and solve issues that may arise plays the most critical role in creating a safe environment. The quality of construction materials used for the construction of sports facilities is of great importance. In this work, the resistance and water repellency of concrete constituents for the construction of sports buildings have been investigated by nanoscience. Nano-concrete material solves the main problem of concrete surfaces, i.e., the entry of water and humidity into the structure. It also gives it a self-cleaning ability with its water repellency. Nanoparticles are placed between pores and cover the cracks, which causes roughness in the surface structure of concrete. The high roughness of the surface of the coated concrete caused its super-hydrophobicity. In hydrophobic surfaces, the higher the contact angle, the more hydrophobic the surface will be. In order to investigate the hydrophobic properties, silica nanoparticles, silica nanoparticles, and fly ash were prepared on concrete, and their properties were analyzed.

This study presents a paper on the implementation of a Raspberry Pi-based educational smart farm system. It confirms that in a real smart farm environment, the control of temperature, humidity, soil moisture, and light intensity can be smoothly managed. It also includes remote monitoring and control of sensor information through a web service. Additionally, information about intruders collected by the Pi camera is transmitted to the administrator. Although the cost of existing smart farms varies depending on the location, material, and type of installation, it costs 400 million won for polytunnel and 1.5 billion won for glass greenhouses when constructing 0.5ha (1,500 pyeong) on average. Nevertheless, among the problems of smart farms, there are lax locks, malfunctions to automation, and errors in smart farm sensors (power problems, etc.). We believe that this study can protect crops at low cost if it is complementarily used to improve the security and reliability of expensive smart farms. The cost of using this study is about 100,000 won, so it can be used inexpensively even when applied to the area. In addition, in the case of plant cultivators, cultivators with remote control functions are sold for more than 1 million won, so they can be used as low-cost plant cultivators.

Several studies have attempted to test students' misconceptions of physics and to provide teaching strategies in order to repair them. The results from these studies have revealed that the diagnosis of students' misconception is crucial, although they often failed to grasp the practice of its implementation. In terms of being a type of methodology for science education, the Internet allows large-scale surveys and investigations to be carried out in a relatively short period of time. This paper reports the results of the development, implementation, and evaluation of a WEb-based SYStem for TEsting students' Misconceptions in physics (WEBSYSTEM) aimed at three groups (science educational researchers who study students' physics conceptions using the system as a detector, school science teachers who practice it as an instructional material, and students who benefit from it for their self-directed learning). The web-based testing system is based on a review of the instructional development strategies of ADDIE (Gustafson, Branch, 2002; Rha, Chung, 2001). Results showed that WEBSYSTEM could work effectively as a multi-purposed tool for the three target groups with a further partial revision, providing educational researchers with resourceful data to study students' misconceptions in physics. Issues of administrative strategies, reexamination of questionnaires, and international collaboration via WEBSYSTEM are discussed.
