ABSTRACT Introduction: Taekwondo is one of the main events of the Olympic Games. It mainly uses hands and feet for fighting or confrontation and the competition is extremely fierce. Therefore, Taekwondo is more prone to muscle, bone, and joint sports injuries. Objective: To understand the characteristics of taekwondo sports injuries. Methods: Using the literature and questionnaire survey methods, mathematical statistics is used to investigate the sports injuries of young Taekwondo athletes. Results: Among 100 young Taekwondo athletes, 93individuals had different degrees of sports injuries, accounting for 93%, and 7had no sports injuries, accounting for only 7%. The total number of injuries was 160 or 1.6injuries per capita. Conclusions: Athletes should improve their ideological understanding and training level and pay attention to the timely treatment of acute injuries, which can effectively reduce sports injuries. Level of evidence II; Therapeutic studies - investigation of treatment results.

The book traces major concepts including: the creation of the visual effects of accuracy through careful action and training; the development of visual judgment and connoisseurship; the role of a network in the production of knowledge; balancing readers’ expectations with representational conventions; and the effects of acts of collecting on the creation and circulation of knowledge. On the one hand, this study uncovers that approaches to knowledge production were different in the seventeenth century, as compared with in the twenty-first century. On the other, it reveals how the early modern struggle to sort through an overwhelming quantity of visual information - brought on by major changes in image production and circulation - resonates with our own.

The Generative Models have gained considerable attention in unsupervised learning via a new and practical framework called Generative Adversarial Networks (GAN) due to their outstanding data generation capability. Many GAN models have been proposed, and several practical applications have emerged in various domains of computer vision and machine learning. Despite GANs excellent success, there are still obstacles to stable training. The problems are Nash equilibrium, internal covariate shift, mode collapse, vanishing gradient, and lack of proper evaluation metrics. Therefore, stable training is a crucial issue in different applications for the success of GANs. Herein, we survey several training solutions proposed by different researchers to stabilize GAN training. We discuss (I) the original GAN model and its modified versions, (II) a detailed analysis of various GAN applications in different domains, and (III) a detailed study about the various GAN training obstacles as well as training solutions. Finally, we reveal several issues as well as research outlines to the topic.

Batam is the third most visited city of foreign tourists due to the strategic location that closes to Singapore and Malaysia. It becomes a distinct advantage with the number of tourists visiting. In addition to marine tourism and shopping tourism, Batam has agro-tourism in the islands around Batam Island. Cafe Zore in Rempang Island's dragon fruit plantation is often visited by domestic and foreign tourists. Foreign tourists often experience difficulties in communicating with English because the employees could not speak English. It is aimed to develop employees' English skills through methods of community education and training with lecturing, discussion and demonstration techniques. The result of this training was the improvement of the English spoken ability. To sum up this PkM activity is that English communication skills are very important to welcome foreign tourists visiting and support the government to develop tourism in Batam

With the current outbreak of the corona virus, all sectors must start to improve so that they can survive during a pandemic, including the education sector. The teaching and learning process carried out during a pandemic situation like this is carried out using an online system and distance learning. Teachers must be able to provide facilities so that students can absorb the material optimally. Another problem that arises is that not all teachers are able to implement the distance learning system and also using the applications or technologies that support distance learning system. To solve this problem, the school needs to get the training of how to make a distance learning system media and in this case the school cooperates with STMIK STIKOM INDONESIA (STIKI) for the training. The training materials provided are google classroom training, google form and training on making the learning videos. The results of the analysis were obtained from the pretest and posttest questionnaires which were described descriptively. After receiving the training, most of the teachers will switch to use the Google Classroom media instead of WA social media, because 100% of the teachers stated that Google Classroom is very helpful in supporting online learning. In addition, according to the posttest questionnaires, 8.3% of the teachers understand very well about the features contained in Google Classroom, 41.7% understand it well and 50% are understand it quite well, meaning that most of the teachers understand the use of Google Classroom. The training also received a good responses from SDN 2 Kawan School and it will be applied  to support their distance learning system.

Research relevance: socialization includes all the processes of communication with upbringing, education and culture, thanks to which a person gets the opportunity to participate in public life and social character. The whole environment of a person is involved in the process of socialization: family, neighbors, peers in children’s institutions, schools, the media, etc. Research objectives: specialized psychiatric or suicidal methods are medical and psychotherapeutic methods of treatment aimed at treating mental and behavioral disorders that lead to suicidal behavior and preventing the onset and recurrence of suicidal activity. Research materials and methods: psychological forms of prevention of suicidal behavior include the formation of anti-suicidal behavior, changes in personal attitudes, self-esteem, level of motivation, etc. includes targeted psychocorrection programs. Research results: reconstruction of the education system and public education will be successful only if it is the work of the whole society. Conclusions: it is important to focus all social life, social-cultural environment, education and training system on the younger generation.
