In this paper, we proposed the automatical recognition algorithm of bar-code using a vision system, which can be used in the industrial application(code 93). The proposed algorithm extracts the pixels which consist of the bar-code modules unrelated to rotation, then that obtains the elements which consist of bars and spaces. After the obtained elements are divided by nine group, the value of bar-code is recognized. The performance of proposed algorithm is verified through the simulation. The proposed one has good performance.

With the steady rise in global popularity of the Korean music group BTS, the South Korean government and surrounding industries have swiftly begun utilizing their image and international recognition for specific nation branding purposes. While K-pop soft power strategies are not novel to the South Korean state, what is new is the rapid speed at which BTS have become a beacon for South Korean culture, language, and symbolism in the international arena. However, few scholarly works have sought to investigate the role fans have played in this heightened position for the group as state representatives, with minimal research conducted into the work fans do within the framework of ARMY fan culture. This paper will thus aim to fill the gap in scholarship on ARMY as an organized labour network, focusing on the role fans play as labourers in online spaces that work to promote, disseminate, and cultivate wider recognition for BTS as artists. Through the conjunct engagement of a political economy framework and theories of participatory culture, this paper will explore the manner through which the free labour of ARMY, premised on affect, has constructed the fandom as active agents of soft power alongside BTS themselves.

The studies of document recongnition have been focused mainly on Korean documents. But most of documents composed of Korean and other characters. So, in this paper, we propose the document recognition system that can recognize the multi-size, multi font and mixed type characters. We have utilized a large scale network model, "CombNET" which consists of a 4 layered network with combstructure. And we propose recognition method that can recognize characters without discrimination of character type. The first layer constitutes a Kohonen's SOFM network which quantizes an input feature vector space into several sub-spaces and the following 2-4 layers constitutes BP network modules which classify input data in each sub-space into specified catagories. An experimental result demonstrated the usefulness of this approach with the recognition rates of 95.6% for the training data. For the mixed type character documents we obtained the recognition rates of 92.6% and recognition speed of 10.3 characters per second.

Object recognition is a technology that detects and identifies various objects in images and videos. LBP is a descriptor that operates robustly to illumination variations and is actively used in object recognition. LBP considers the range of neighboring pixels, the order of combining the neighbors after the comparison operation, and the starting position of combining. In particular, the starting position of the LBP becomes the "most significant bit"; it dramatically affects the performance of object recognition. In this paper, based on the N starting positions, the data most similar to the input data are searched in each of the N feature spaces. Object recognition is performed by the confidence measure that can compare different results of each feature space under the same criterion and select the most reliable result. In the experimental results, it was confirmed that there is a difference in performance depending on the starting position of LBP. The proposed method showed a high performance of up to 12.66% compared to the recognition performance of the existing LBP.

The finger language is the part of the sign language, which is a language system that expresses vowels and consonants with hand gestures. Korean finger language has 31 gestures and each of them needs a lot of learning models for accurate recognition. If there exist mass learning models, it spends a lot of time to search. So a real-time awareness system concentrates on how to reduce search spaces. For solving these problems, this paper suggest a hierarchy HMM structure that reduces the exploration space effectively without decreasing recognition rate. The Korean finger language is divided into 3 categories according to the direction of a wrist, and a model can be searched within these categories. Pre-classification can discern a similar finger Korean language. And it makes a search space to be managed effectively. Therefore the proposed method can be applied on the real-time recognition system. Experimental results demonstrate that the proposed method can reduce the time about three times than general HMM recognition method.

This study investigates the historical formation and characteristics of modern Korean consumption culture by reviewing previous literature about consumption spaces and conspicuous consumption in modern Korea. This study examined the historical formation and characteristics of three different periods of time: from 1876 to 1919, from 1920 to 1936, and from 1937 to 1945. In addition, the current study reviews previous literature related to advertising, poems, novels, historical events, and Orientalism. Based on this, the historical characteristics were also analyzed. The overall results were as follows: The first period from 1876 to 1919 was the beginning of modern Korean consumption culture, in which exotic goods such as foreign fabrics were preferred and consumed. In addition, clothing was simplified and westernized through modern reform. The second period of time, 1920 to 1936, was the development stage of modern Korean consumption culture that formed the foundation of modern consuming spaces where the recognition of the human form became more modern, and 'modern girls' styles appeared. The final period, 1937 to 1945, was the regression stage of Korean modern consumption culture, in which consumption decreased during the Sino-Japanese War and World War II. The results of this study' conclude that the leading-consumer items hold symbolic value as well as became signifiers within modern consumption spaces such as modern Korean department stores and that women were recognized as modern leading-consumers as shown by the dramatic increase in the number of products that targeted women.

In the architectural space of modem age, expanding to the vertical and horizontal direction for the interaction between space and space is becoming an indispensable factor, and in this expansion, ramps are being positioned as one of the important factors. With an increased use of ramps, they show a variety of changes in types, functions and even concepts. The space where modem ramps are used exhibits a phenomenon that accommodates and expands many functions as well as the confined function of moving people, and is widening the scope of recognition on the functions of ramp. In addition, this phenomenon can be seen as an architectural reflection on the complexation trend of the modem society, the components comprising a ramp contact the body of experiencers closely and thus have a direct effect on their behavior or feeling, and owing to this, it is a space where new functions and meaning are highly likely to be derived. In this study, spaces where ramps are used stay away from an element of uniform vertical movement but have an independent environment within the entire space, thereby being used as a space dominating the nature of the building, not a subsidiary element of it. In this study, therefore, it could be known that spaces in which ramps are used are different in their meaning according to the patterns, not as an element of uniform vertical movement. In addition, these conclusions are the results by analyzing the patterns of ramps taking place in modem spaces and are thought to be helpful in understanding spaces where ramps are used.

In light of the recent increase in new independent spaces within the field of artistic production, this study seeks to examine the daily experience and art practice of agents in such spaces. In-depth interviews were conducted with fifteen emerging artists, who manage new independent art spaces and participate actively in related activities, and the significance of their activities was analyzed. An important theoretical foundation of this study is Bourdieu's concept of the field of cultural production. According to Bourdieu, in order to understand a specific field, the habitus of agents must be studied together with the structure of the field. This study found that individuals belonging to the same or a close generation exhibit similar attitudes to life based on shared experiences, and they can be connected to their art practice. Most agents of new spaces did not have high expectations for success, and chose to practice art independently while bonding with their peers and enjoying the moment rather than wait for recognition or funding from external sources. Their self-fulfilling habitus is condition-specific and can be regarded as a form of flexible art practice. Given the poor conditions of today's field of artistic production, this is likely to serve as an advantage in entering the field and in position-taking. The social significance of this study lies in the fact that the aforementioned characteristics of the agents of independent production spaces not only reflect the current field of artistic production but also other fields of cultural production at large in our society.

This paper proposes an efficient method of object identification and localization for image recognition. The new proposed algorithm utilizes correlogram back-projection in the YCbCr chromaticity components to handle the problem of sub-region querying. Utilizing similar spatial color information enables users to detect and locate primary location and candidate regions accurately, without the need for additional information about the number of objects. Comparing this proposed algorithm to existing methods, experimental results show that improvement of 21% was observed. These results reveal that color correlogram is markedly more effective than color histogram for this task. Main contribution of this paper is that a different way of treating color spaces and a histogram measure, which involves information on spatial color, are applied in object localization. This approach opens up new opportunities for object detection for the use in the area of interactive image and 2-D based augmented reality.

The objective of this paper is to evaluate most useful feature vector space using the angle, velocity and location features from gesture trajectory which extracted hand regions from consecutive input images and track them by connecting their positions. For this purpose, the gesture tracking algorithm using color and motion information is developed. The recognition module is a HMM model to adaptive time various data. The proposed algorithm was applied to a database containing 4,800 alphabetical handwriting gestures of 20 persons who was asked to draw his/her handwriting gestures five times for each of the 48 characters.
