Economic transformations have led to an increase in the role of creative assets and their central role in public life. Changes in creative activity have led to a change in the organization of the work of institutes engaged in the training of specialists, in particular teachers of labor education. Methods and approaches to training determine the development of creative industries, being the basis for models of professional training of future teachers of labor training. The purpose of an article was to develop a modern model of professional training of future teachers of labor training based on the concept of creative economy. The methodology is based on the concepts of holistic craft and creative economy. Based on the integration of pedagogical learning models "Craft as design and problem-solving", "Craft as skill and knowledge building", "Craft as product-making" and "Craft as self-expression" developed and experimentally confirmed the conceptual model of professional training of future teachers of labor training. The proposed model forms a practitioner with professional, technical, digital and creative skills who is able to transfer the experience to students. The training course "Creativity and creative thinking" has been developed. The model provided for the development of a course based on the strategy of developing professional creativity, flexibility, improvisation, openness, student activity, joint practice, student-oriented approach. The practical value implies the adaptation of the developed model of professional training of future teachers of labor education during the training of teachers in higher education, which is confirmed in the experiment.

The construction craft workers have been getting older and have become drained, in spite of the vital factor that it directly affects productivity and quality as a final producer. This situation in the construction industry is ultimately due to evasion of performances by young craft workers. Therefore, the aim of this study is to propose the certification and level system of construction craft workers and to extract young craft workers from the market for construction craft workers so as to supply and demand high quality of craft workers. First of all, the present status and problems of the domestic construction craft workers are considered in this study. Furthermore, the appropriate way to establish its certification and level system is suggested from the Interview with experts, as well as references of German and Australian case. The revitalization of certification and level system provided in this study is expected to ensure that the craft workers are not simple laborers, but are required the professional knowledge and skill. Besides, it will lead to strengthen specificity and to break from aging, by taking young and qualified craft workers into the construction industry. Also, it will promote an employment stability by connecting the social security system.

A space system refers to a network of sensors, ground systems, and space-craft operating in space. The security of space systems relies on information systems and networks that support the design, launch, and operation of space missions. Characteristics of space operations, including command and control (C2) between space-craft (including satellites) and ground communication, also depend on wireless frequency and communication channels. Attackers can potentially engage in malicious activities such as destruction, disruption, and degradation of systems, networks, communication channels, and space operations. These malicious cyber activities include sensor spoofing, system damage, denial of service attacks, jamming of unauthorized commands, and injection of malicious code. Such activities ultimately lead to a decrease in the lifespan and functionality of space systems, and may result in damage to space-craft and, lead to loss of control. The Cybersecurity Adversarial Tactics, Techniques, and Common Knowledge (ATT&CK) matrix, proposed by Massachusetts Institute of Technology Research and Engineering (MITRE), consists of the following stages: Reconnaissance, Resource Development, Initial Access, Execution, Persistence, Privilege Escalation, Defense Evasion, Credential Access, Discovery, Lateral Movement, Collection, Command & Control, Exfiltration, and Impact. This paper identifies cybersecurity activities in space systems and satellite navigation systems through the National Institute of Standards and Technology (NIST)'s standard documents, former U.S. President Trump's executive orders, and presents risk management activities. This paper also explores cybersecurity's tactics attack techniques within the context of space systems (space-craft) by referencing the Sparta ATT&CK Matrix. In this paper, security threats in space systems analyzed, focusing on the cybersecurity attack tactics, techniques, and countermeasures of space-craft presented by Space Attack Research and Tactic Analysis (SPARTA). Through this study, cybersecurity attack tactics, techniques, and countermeasures existing in space-craft are identified, and an understanding of the direction of application in the design and implementation of safe small satellites is provided.

CE RCD (Recreational Craft Directive) is a certification for the design and construction of small vessels, including pleasure yachts, which are widely used not only in the countries within the European Union, but also in Japan and Southeast Asia. Recently, South Korean leisure craft shipyards have developed interest in exporting to foreign leisure craft markets such as Europe; however, they have encountered difficulties because of the CE RCD regulations, which are relatively complex and difficult to understand. The requirements for buoyancy and stability, which are essential properties that must be understood within the early stage of ship design, are defined based on ISO 12217. However, preparing this assessment according to ship classification regulations is an exceedingly complex task, even with knowledge of naval architecture. In this research, we have developed design support tools to systematically support assessments and preemptively define design information so that buoyancy and stability assessments based on ISO 12217 can be systematically prepared. Our research results were applied to actual examples of yacht design to confirm validity. We believe that the improved yacht design process presented in this research can act as a foundational reference for enhancing the effectiveness and systematic buoyancy and stability assessments.

It's been a common knowledge that Indonesia has a multicultural nature which produces a rich civilization, traditional textiles is one of the examples. Indonesian textile is one of the earlier/oldest artefacts being studied. The wide range of its selections also a proof that Indonesia already had an advanced culture. In Indonesia, textile isn't just a mere cloth; it also used to refer your social statuses, a ritual complements aspect, and many other symbolic purposes. Celebes textiles just a small example how rich this country culture is. The purpose of this study was to convince people that Indonesian traditional textile has a potential to stand in same ground with any modern textile produced around the world.

Tuban area in East Java, Indonesia, has a role as one of international ancient trading ports since 11th century. For that role, Tuban has accepted many foreign cultures that are brought by other nations, such as Tionghoa and Gujarat. The improvement of Tuban that involves international relationship clearly influences the forms of tradition and culture that is shown in Tuban nowadays. It is believed that from those tradition and cultures owned by people of Tuban, producing cloth is one of the oldest tradition maintained by the people. Those clothes, as one of traditional products, have unique identity that differ them to other regions. It is because the uniqueness of people's knowledge about cosmology concept, and skill owned by the people that passes through generations. This research explains the condition of traditional cloth tradition of Tuban society with fundamental ground data and explains elements that intervenes the tradition, and forms resulted from it.

In a rapidly changing fashion design world, creative ideas are always required. Knowledge has been created as an art, exhibiting a new imagination that surpasses reality, while being visualized from the past. The purpose of this study is to derive types of visualization of knowledge for continuous creation of fashion design. The study consists of literature and empirical studies. ATTA, a creativity evaluation method made by Torrance applied for analyzing of Gucci fashion design collections from 2016-2017. Creativity of the Gucci collection by ATTA evaluation items are that first, a vivid idea was revealed through collection history, myths and animal and plants, second, conceptual incongruity is in the composition of the garment, third, provocative questions are the symbolism of the meaning of the text, fourth, different perspectives derive a new formative beauty through the synthesis of twisted elements, fifth, abstraction is a symbolic expression of animals and plants, sixth, synthesis is a mixture of various materials and techniques by plural inspiration, seventh, context, it is developed as a design accompanied by stories of history and myth and eighth, fantasy is fictitious animals and animals and detail. In addition, formativeness of fashion design by visualization of this knowledge was extracted with contamination, symbolism, enjoyment and fabrication. Visualization of the knowledge is expected to be used as a strategy to attract ongoing ideas for creative fashion designs.

With the expansion of the Russian Empire southward in the nineteenth century, connoisseurs, art historians, and scholars in Russia began to pay attention to carpet traditions in the new territories of the Russian Empire in Turkestan. In journals and other specialty publications, they underscored a need to establish claims to authority over the knowledge of the traditional craft. They were highly attuned to parallel accounts of carpet weaving from regions that had a longer history of research and collecting of carpets. In contrast to the situation in Western Europe or the United States, commentators bemoaned the fact that the public and even professed experts in Russia did not properly appreciate carpets from the Caucasus and Central Asia. These scholars articulated a need to establish authority over the carpet weaving traditions of Russia's colonial possessions, resulting in a push toward a serious study of carpet weaving as a legitimate field of inquiry. This paper uses published sources on early carpet scholarship from the late nineteenth and early twentieth centuries to examine how carpet weaving traditions in Central Asia entered an imperial discourse of knowledge. It argues that attempts to understand and categorize carpet weaving as an art form occurred along two fronts. Intellectuals and scholars attempted to wrest control over the locus of knowledge from experts in the West as well as from local weavers. In the process, they established a distinctly imperial vision of carpet weaving in contrast to competing imperial discourses and over traditional forms of knowledge.

Recently, reinforcement learning combined with deep neural network technology has achieved remarkable success in various fields such as board games such as Go and chess, computer games such as Atari and StartCraft, and robot object manipulation tasks. However, such deep reinforcement learning describes states, actions, and policies in vector representation. Therefore, the existing deep reinforcement learning has some limitations in generality and interpretability of the learned policy, and it is difficult to effectively incorporate domain knowledge into policy learning. On the other hand, dNL-RRL, a new relational reinforcement learning framework proposed to solve these problems, uses a kind of vector representation for sensor input data and lower-level motion control as in the existing deep reinforcement learning. However, for states, actions, and learned policies, It uses a relational representation with logic predicates and rules. In this paper, we present dNL-RRL-based policy learning for transportation mobile robots in a manufacturing environment. In particular, this study proposes a effective method to utilize the prior domain knowledge of human experts to improve the efficiency of relational reinforcement learning. Through various experiments, we demonstrate the performance improvement of the relational reinforcement learning by using domain knowledge as proposed in this paper.
