Authors: Et. al. Netty Huzniati Andas, 
Published: April 2021

Speaking is the art of conveying ideas and feelings by generating and sharing meaning through oral contact. Pow-Tega is a speaking skill teaching technique that combines a power teaching technique with a game to allow students to practice their speaking skills. Students' focus and excitement in speaking are developed using the power teaching technique. Students were inspired to study while playing the game because the classroom environment was more colorful. Researchers used a quantitative method by assigning pre-experimental studies with one group pre-test and post-test to determine the impact of the Pow-Tega technique on students' speaking performance. This study included 33 students as participants. The researchers used a spoken test and video recording to gather data. Before beginning treatment, researchers gave all of the samples a pre-test, then began treatment by using the Pow-Tega Technique for six meetings, and eventually, researchers gave all of the samples a post-test. The results revealed that the mean post-test score (3,93) was higher than the pre-test score (3,39). Furthermore, at the significant stage of 0,05 and degree of freedom -19, the ttest (6,75) was higher than the ttable (2.093). H0 has been refused, while H1 has been accepted. That means there was a significant effect of students’ speaking ability after they were taught by using Pow-Tega.
Kazakh sports culture: theory and practice
Authors: Et. al. Sapanov S.Zh, 
Published: April 2021

T Important theoretical aspects are considered in this article: the origin and essence of the Kazakh controversial culture. Sport competitive culture is the only part of the general agonistics, which includes various other kinds of competitions: poetic, musical etc., and Kazakh controversial culture is a part of the universal human culture.
The questions of sports culture and philosophy, especially its agonistic context, seem to be the most complex, interesting and relevant. However, deep theoretical development is required to understand the essence of agon in the world and national sports culture, as one of the most socially demanded and the most developed variety of culture.
Agonistics as a cultural phenomenon attracts the attention of the world scientific community: culturologists, philosophers, art historians, economists, teachers, etc. We have taken the Kazakh example, the method of comparing the world's agon with the Kazakh tradition: its ancient sources, its national-specific characteristics, its organic connection with the initial bases: martial arts, rituals and sports games of ancient Turkic peoples to identify the essence, origin, forms of agon. Such a national-theoretical approach sheds light not only on the specifics, but also on the general laws of the development of a sport-competitive culture, on the common origins and the universal essence of adversarial (agon) in its various manifestations and not only sports. The article explores theoretical approaches, interpretations of foreign, Kazakh philosophers and culturologists. This scientific theoretical and methodological base is of fundamental importance for studying the essence and genesis of world sports and sports phenomena.

Particles pre - equilibrium spectra and angular distribution are calculated by usingFeshbach-Kerman- Koonin (FKK) model with PRECO-2006 code. The angular distribution of the nuclei of nuclear reactions between the nucleus of a target (90Zr) and the tapline of light particles wascalculated by using reactions of the multistep compound (MSC) and of multistep direct (MSD).Isospin, the finite well depth, and shell effects are considered. Byusing [(_40^90)〖Zr〗_50 ] as target material the cross section of [90Zr(n,n)90Zr], [90Zr(n,p)90Y], [90Zr(n,D)89Y], [90Zr(n,T)88Y], [90Zr(n,3He)88Sr] and [90Zr(n,4He)87Sr] reactions were estimated. Values of cross sections estimated are 550, 371, 16.3, 4.55, 0.271 and 2.35 mb/MeV respectively. Also the angular distribution of same nuclear reactions were estimated, and the values of angular distribution are 850, 392, 4.55, 4.55,0.27 and 2.35mb/sr.MeV respectively.
Real Distance Measurement Using Object Detection of Artificial Intelligence
Authors: Et.al Jae Moon Lee 
Published: April 2021

Artificial intelligence technology is developing rapidly in recent years. The purpose of this paper is to measure the distance to an object using this. In order to measure the distance, two separate pictures from same angles of the object will be taken. It extracts sizes for the same object in two pictures. In order to do this in real time, object detection technology of Artificial Intelligence on mobile phone was used. In this paper, a method for measuring the distance from two pictures is presented. The proposed method was implemented as a prototype on iOS. In order to measure the performance of distance measurement, experiments were conducted in various environments. In the experiments, the empirical data yielded some discrepancies with the actual measurement. This was a result of errors occurring in the object detection process where the actual size of the object was calculated. Despite these discrepancies, this method of object detection may be widely used in instances where accurate measurements are not necessarily required such as guidance systems for the visually impaired.

Received:11 november 2020; Accepted: 27 December 2020; Published online: 05 April 2021
Abstract: Drones are used in agriculture and external control, utilizing cameras, various sensors, and autonomous flight functions. However, it is difficult to fly for a long time because of flying with heavy equipment. Therefore, it is necessary to increase the flight time through lightening of the drone itself and efficient control of the BLDC motor. That is, it is necessary to improve the motor itself, which accounts for most of the energy consumption in drone flight. Stator fabrication of existing BLDC motors is done by winding copper wires through individual processes on the stator core through an automated process. However, in the case of an ultra-small BLDC motor, the stator core has a small size and is manufactured using a thin-diameter copper conductor, and thus has a lot of problems in the automation process. Therefore, in this paper, the multi-division coupling structure method of individual teeth of the stator was applied through a new type of BLDC motor stator design. That is, the cartridge type BLDC motor stator was applied to improve and reduce the BLDC motor stator method. Through this, the performance limit of the BLDC motor was improved by combining individual teeth with multiple cartridges. The cartridge type BLDC motor is manufactured by stacking several cartridges on each tooth. Therefore, various performances can be produced according to the connection state of the cartridges

Authors: Et.al Ye-Won Park 
Published: April 2021

Background/Objectives: Quality control can improve the quality of medical care along with the stability of diagnostic X-ray generator. Regular quality control provides reliable quality control of the machine and maintains consistency of general imaging using radiation for efficient diagnosis.
Methods/Statistical analysis: A phantom for quality control of diagnostic X-ray generator was produced using a 3D printer. Quantitative and qualitative evaluation of the phantom utility was conducted by modifying images acquired using S and D companies’ tools with Source to Image-Receptor Distance (SID) levels ranging between 130 cm and 180 cm. The evaluation indices were determined based on the analysis of field compliance, uniformity, low and high-contrast resolution, and linearity.
Findings: The evaluation was conducted by acquiring and changing the radiographic image to SIDs between 130 cm and 180 cm using the indigenous phantom. The field compliance of S and D companies in terms of quantitative evaluation indices was both appropriate within ± 1% according to the SID change. To ensure a uniform SID 130 cm, the internal and external means of S company were 893 and 943, respectively, while those of the D company were 228.1 and 261.4, respectively. At an SID of 180 cm, the internal and external means of the S company were 928.1 and 958.4, respectively, while those of the D company were 257.2 and 299, respectively. A characteristic of the DR system was identified to ensure linearity, altered exposure dosage according to the step wedge height, and the difference in SI values according to the characteristics of the equipment and linearity. The qualitative evaluation indices were determined by identifying the size of the hole under high-contrast resolution up to 0.8㎜ and the bar size up to 1.6 lp/㎜. The low contrast resolution was evaluated with a C-D pattern, and at SID 130 cm, the S company scored 124.6 points and the D company 116 points, and at 180 cm, the S company scored 111.4 and the D company 104.6 points.
Improvements/Applications: The utility of the homegrown phantom in quality control was confirmed for each index. The medical institutions are required to introduce quality control regulations for general image examination using radiation. It is helpful to efficiently manage old equipment and improve public health and medical care by linking with the health insurance fee.

Authors: Khodaei Mohamad , Valanezhad Alireza 
Published: April 2021

Introduction: Zirconium oxide or zirconia have been used for the fabrication of dental implants due to their biocompatibility, hardness, toughness, compressive strength and chemical stability. The aim of this study is investigating the effect of sintering time on the properties of zirconia dental implant.
Materials and Methods: In this research, which was performed at Department of Dental and Biomedical Materials Science, Nagasaki University, Nagasaki, Japan, at 2019, zirconia-yttria mol.% 3 powder was pressed and sintered at 1450°C at different times (5 samples for each condition) and the effect of time on the phase, structural and mechanical properties of the sintered samples was investigated. One-way ANOVA statistical analysis was performed with the 0.05 level of significance using Graph Pad Prism 6 software.
Results: The results of XRD phase analysis show that sintering time change has a significant effect on the phase changes of the samples and the Vickers hardness of the samples shows a significant increase with increasing sintering time due to shrinkage and decrease in porosity of the samples. But the 12 hour times of sintering caused phase changes in the samples which is not desirable.
Conclusion: Therefore, for the fabrication of zirconia parts with minimum porosity and optimum hardness, a moderate sintering time (6 hours) is recommended.
