During the 1980s, Textile design achieved a remarkable growth in creating aesthetic effect and in establishing its standing by responding to demands of the time effectively and seeking changes proactively. This was a period when Textile design constructed its modern concept as it was attempting a qualitative improvement through advanced technology, high class, and differentiation. The advent of advanced materials through the development of textile engineering, employment of craft techniques to further cultural and artistic orientation, and restoration of decorativeness in pursuit of sensitivity, all these developments of the 1980s contributed to the rise of above characteristics. In this study, attempts are made to grasp the new trend of Textile design during the 1980s and to review diverse methods of aesthetic creation and plastic possibility which this trend presented for the Textile, and thus to recognize the role of Textile design and its importance in a new light. The new trend of Textile design during the 1980s can be summarized as follows: 1) An appreciation of the creative aspect of the Textile. As attempts are made to emphasize visual and sensitive aspects of the medium, Textile tended to become an object of art itself. 2) A new awareness of the representative and plastic capacity of the fiber material. As attempts are made to develope the creative potential of the Textile, representation of the material tended to become more diversified. 3) A recognition of the Textile as a proper means to deliver the spirit of the time. As the medium accommodates and fuses diverse cultures including traditional culture, more emphasis was place on cultural contents of the Textile. In the process of pursuing these changes, Textile design of the 1980s has also contributed to the creation of new values, laying the groundwork for its emergence as an advanced high value-added industry.

This study explores of the lowest social class segregation in the residential area of Yao city of the Osaka Prefecture. The Buraku people, who constitute a social class that was the object of societal discrimination and exclusion since the beginning of modem times, formed a segregated residential area of their own. During the process of an organized struggle against discrimination that was institutionally recognized, communal consciousness among the constituents was consolidated. Moreover, in the Yao city, Korean immigrants in Japan, another discriminated group, as well as Vietnamese refugees and Chinese, who are also social minorities, increased in number. Also, activities by the Buraku people and Korean immigrants in Japan to defend human rights and the rights of social minorities began to unfold. Recently, the number of small scale factories in the Buraku's Douwa District decreased due to relocation of manufacturing companies elsewhere throughout Japan and to the effects of depression. New non-Buraku houses began to appear one by one on the site where factories started to disappear. While the spatial separatism of Yao city, as part of the isolated Douwa District, is weakening, the struggle based on communal consciousness among the social minorities and continued human rights activity is exerting great influence upon the administrative policy of Yao city. In the case of Yao city, while the visual appearance of spatial segregation is weakening, the communal consciousness among the regional residents remains. From this perspective, it can be said that this case represents a modified form of isolated space or the social pattern of segregation which is in the stage of extinction.

Seoul is an ancient city with a long history but there is hesitancy over referring to as a historic city due to the lack of traceable historic urban landscape elements which resulted from numerous invasions and general destruction. From a diachronic perspective, the nature which was survived the influence of development, could be the key element that links the past with the city's radically changed image in modern times. Although "old big trees" may be not a dominant influence with regards to the historical authenticity of the city, they are objects which contribute towards the historical authenticity by providing a sense of place in terms of connected narratives, as well as their natural image. However, the protection policy for an "old big tree" would place too much emphasis on the aspect of the ecological value rather than its cultural value. Generally, trees have been protected by installing a fence and a signboard around them as well as receiving additional care. However, it is difficult to find that surrounding space around the "law-protected tree" is connected with its original historical and cultural values. Even though the space around trees are no longer utilized in the same way as was so in the past, they still have high-potential in terms of cultural utilization. Therefore, the subject of this study is the "old big tree" as a natural object which contributed to the historical authenticity of Seoul. The current status of these "old big trees", aged between 100 and 800 years old, currently indicate that there are 215 trees designated as "law-protected tree" by the Seoul metropolitan government. This study aims to investigate the status of protection and utilization of the existing "law-protected trees" in the city of Seoul and find a way to increase both ecological preservation and cultural utilization for the high-potential "law-protected trees" within the city itself. In order to achieve this, previously researched papers shall be reviewed and surveyed pertaining to present usage patterns of the 215 "law-protected trees". In addition, five cases have been reviewed which focus on a few of utilizing the "protected trees" and their surrounding spaces. The results of the research indicate that 21 "old big trees" have high-potential in terms of cultural utilization as well as ecological value. However, it was revealed that there are limitations to pursue the value of preservation and utilization simultaneously throughout current regimental management. In order to cope with the current situation, it is pointed out that management facilities should be designed and installed by creative and flexible methods of organizing with consideration to the surrounding space and context. Even though in the case where there may not be a connecting history or legendary stories, the "old big trees" can serve as the fundamental features of small scale parks -dependent on their location, condition and environment- which will be of value to the local communities. This study could serve as a practical reference for the management and utilization of "old big trees" nationwide with numbers reaching 12,300 besides the city of Seoul.

Part of public arts, environmental builforms not only enhance the beauty of a building, but also serve to stabilize the citizen's psychology and as a landmark having intimate values with the city environment and symbolic meanings. Thus they do have sociocultural values as an original formative artwork. The purpose of this study was to suggest evaluation and review methods and an evaluation framework for environmental builtforms, which had legal binding under the building decoration system, to a local government to improve the quality level of urban environment. It will be such a distant goal of creating a desirable urban environment as long as environmental builtforms are merely regarded as an object to follow a vogue and a mandatory passage procedure. It's important to take a perspective of an expert to set up and suggest an evaluation system in the public aspects. In the study a consideration was made of the current systems and review criteria of environmental builtforms, which was followed by the development of a theoretical research model and of a framework for statistical evaluation by a group of experts. The questionnaire designed based on the theoretical research model was tested for validity and reliability. Its pilot test results were then analyzed to verify the hypotheses. The questionnaire collected twice were statistically analyzed in exploratory and confirmatory factor analysis with the SPSSWIN 11 program. All the analysis results were used to come up with a final evaluation framework.

A time-series database is a set of time-series data sequences, each of which is a list of changing values of the object in a given period of time. Subsequence matching is an operation that searches for such data subsequences whose changing patterns are similar to a query sequence from a time-series database. This paper addresses a performance issue of time-series subsequence matching. First, we quantitatively examine the performance degradation caused by the window size effect, and then show that the performance of subsequence matching with a single index is not satisfactory in real applications. We argue that index interpolation is fairly useful to resolve this problem. The index interpolation performs subsequence matching by selecting the most appropriate one from multiple indexes built on windows of their inherent sizes. For index interpolation, we first decide the sites of windows for multiple indexes to be built. In this paper, we solve the problem of selecting optimal window sizes in the perspective of physical database design. For this, given a set of query sequences to be peformed in a target time-series database and a set of window sizes for building multiple indexes, we devise a formula that estimates the cost of all the subsequence matchings. Based on this formula, we propose an algorithm that determines the optimal window sizes for maximizing the performance of entire subsequence matchings. We formally Prove the optimality as well as the effectiveness of the algorithm. Finally, we perform a series of extensive experiments with a real-life stock data set and a large volume of a synthetic data set. The results reveal that the proposed approach improves the previous one by 1.5 to 7.8 times.

In this essay I aimed to analyze the concept of cultivation in east asian aesthetics. Most people regarded traditional asian paintings as an artwork that was obviously an artwork by artists. Moreover, they emphasized the cultivation of artists in their creation and used to accept the concept of cultivation which means cultivating one's mind. Generally speaking, to cultivate one's mind meant enlarging one's ethical behavior and he or she became a better person. And in creation, it meant considering all things more deeply. In this point of view, it was too vague to notice the meaning. What is an accurate meaning of cultivate artist's mind? What was the relation between creation and cultivation? In confucian philosophy, the concept of cultivation had two meanings. One was to enlarge one's ethical behavior and the other was to improve one's knowledge about things. The knowledge implied all of the one's experiences about things. Thus, the knowledge meant what he communicated with under his surroundings and created. In this perspective, to analyze the case of "Dohwaguenmungi" and "Limchungochi", cultivation was related to 'you(游)' and 'jing(精)'. It implied all of the artist's efforts to make communication with his objects deeper and wider, at last, he created his own meaning about object that he experienced. Therefore, I suggest that when we use the concept of cultivation in the context of creation, it should be used as the meaning related with improving one's knowledge about things.

The weight of pig is one of the main factors in determining the health and growth state of pigs, their shipment, the breeding environment, and the ration of feed, and thus measuring the pig's weight is an important issue in productivity perspective. In order to estimate the pig's weight by using the number of pig's pixels from images, acquired from a Top-view camera, the posture determining and the head removal from images are necessary to measure the accurate number of pixels. In this research, we propose the fast and accurate method to determine the pig's posture by using a fast image processing technique, find the head location by using a fast deep learning technique, and remove pig's head by using light weighted image processing technique. First, we determine the pig's posture by comparing the length from the center of the pig's body to the outline of the pig in the binary image. Then, we train the location of pig's head, body, and hip in images using YOLO(one of the fast deep learning based object detector), and then we obtain the location of pig's head and remove an outside area of head by using head location. Finally, we find the boundary of head and body by using Convex-hull, and we remove pig's head. In the Experiment result, we confirmed that the pig's posture was determined with an accuracy of 0.98 and a processing speed of 250.00fps, and the pig's head was removed with an accuracy of 0.96 and a processing speed of 48.97fps.

This paper is a study to check the flow of how addiction to media services has been studied from a long-term perspective, and to identify variables that can be the basis for future addiction research. Researchers noted the addiction of media services in adolescents in particular, and identified a combination of factors depending on the background of the times. Addiction variables were largely aggregated into four properties: adolescent properties, personal properties, media properties, and media-dependent properties. Addiction variables belonging to the attribute were influenced by major media and divided into four periods. During the study period, the frequency of variables was most related to personal attributes, followed by media attributes, adolescent attributes, and media-dependent attributes. Also Individual attribute variables gradually shifted from object-relationship to individual psychological factors. Variants in media attributes were influenced by the introduction and spread of new media. Variations in adolescent and media-dependent attributes have been weak in studies that observe teenagers' motivations for media use or are related to addiction, and no papers have been published since 2020. Although addiction research on media services is important in terms of industry, there has been an emphasis on social aspects, based on the results of this study, we hope to continue to study the variables of service users who can be used in terms of industry.

This paper examines discussions surrounding cognitive liberty, neuro-privacy, and mental integrity from the perspective of Neuro-rights. The right to control one's neurological data entails self-determination of collection and usage of one's data, and the right to object to any way such data may be employed to negatively impact oneself. As innovations in neurotechnologies bear benefits and downsides, a novel concept of the neuro-rights has been suggested to protect individual liberty and rights. In Oct. 2020, the Chilean Senate presented the 'Proyecto de ley sobre neuroderechos' to promote the recognition and protection of neuro-rights. This new bill defines all data obtained from the brain as neuronal data and outlaws the commerce of this data. Neurotechnology, especially when paired with big data and artificial intelligence, has the potential to turn one's neurological state into data. The possibility of inferring one's intent, preferences, personality, memory, emotions, and so on, poses harm to individual liberty and rights. However, the collection and use of neural data may outpace legislative innovation in the near future. Legal protection of neural data and the rights of its subject must be established in a comprehensive way, to adapt to the evolving data economy and technical environment.

An on-going creative process was the major principle of Kantor's artistic endeavors. Kantor's emphasis on process grew out of his frustration with the experience of creation being isolated from the audience in the present time, during the moments of encounter. At the same time, however, Kantor was always aware of the fact that the first night of each and every performance that he made was the last point of his creative intervention. Despite being performed live in the present time, Kantor saw theatre essentially as an end product. This does not mean that Kantor abandoned the concept of on-going process, for process was for the artist a means to reject the idea of a finished work of art and to denounce the feeling of satisfaction derived from the traditional denouement in representational theatre. For him, theatre that dominated his time isolated the audience from the art work and the artist, and from this perspective his continual emphasis on process should be understood as an aesthetic principle in order to open up and expand the dimension of art into the realm of the spectator so that the experiences of both the artist and spectator may coexist. The heaviest barrier that separated the artist and his work from its audience was the creative structure that governed Western art. In theatre it was the dramatic structure that was the main object of his series of severe challenges. Not only did it fail to represent reality but it distorted reality, creating nothing but artificial illusion. Under this condition, all that was permitted to the audience was mirages. However, Kantor never completely discarded illusion from his theatre. The point for him was always to created a circumstance where the illusory reality of drama comes to exist within the dimensions of our reality. It was Kantor's belief that instead of a total denial of illusion, his theatre should strategically accommodate illusion which comes from reality. And, the aim of Kantor's theatrical experiments was to invite the audience into this ambience and transform the experience of his audience into a much more participatory one. This paper traces the ways in which Kantor transgressed the dominating conventions of representational, literary theatre, and how such attempts induced an alternative mode of spectatorship. The study will begin from an investigation into Kantor's attitude towards illusion and reality, and then move onto a closer inspection of how he spatially and dramaturgically materialized his concepts on stage, giving special focus on Wielopole, Wielopole.
