  • Extreme sports refers to sports activities with a high level of inherent danger, such as extreme skiing, snow-boarding, mountain biking, motocross bicycling, aggressive in-line skating, wake-boarding, and paragliding. This study investigates the characteristics of extreme sports participants as group identities through an examination of the differences between extreme sports participants and traditional sports groups in lifestyle and sportswear benefits sought. We composed a total 108-item lifestyle profiles characterized by six lifestyle dimensions (dress, diet, home, recreation, consumption, and sense of values); in addition, we developed 32 items for sportswear benefits sought. The surveys targeted 422 sports participants living in Korea (216 men and 206 women, aged 15-23): 119 extreme sports participants and 303 traditional sports participants. All items were evaluated on a 5-point Likert scale, and SPSS 17.0. was used for data analysis. Exploratory factor analysis was conducted to confirm the substructure of each lifestyle dimension and sportswear benefits sought. The results of the factor analysis on each lifestyle dimension are as follows: 5 factors in dress dimension, 4 in diet, 3 in home, 6 in recreation, 5 in consumption, and 6 in sense of values. Six factors of sportswear benefit sought were identified. A t-test revealed that there were significant differences between the two groups in lifestyle dimensions and sportswear benefits sought. This study reveals that the lifestyle characteristics of extreme sports participants are more likely than traditional sports group to be more self-expressive, more distinctive, more fashion-oriented, more conspicuous, and more brand-oriented, while preferring more active sports, more dynamic leisure, and a more sensible life. Another finding is that extreme sports participants seek the distinctive, conspicuous, and latest sportswear benefits.

  • With globalization, national image has become more important. As national competitiveness is stressed, the Olympics is considered as an opportunity to show host country's general capabilities. Positive national image can be built through successful Olympic Games and Olympic emblem is a core element of visual identity to make such Olympic Games successful. This study researches on Olympic emblem based on the fact that emblem is an important visual medium to show national identity. Examples of national identities reflected in the Olympic emblems were reviewed and then categorized by motifs and expression. Trend of such categories has been analyzed from inner-oriented and external-oriented point of view, and characteristics important for those emblems were studied. This study would be able to be used to understand types of national identities reflected in the Olympic emblems, and used as a basic data to effectively establish strategies on national identity.

  • At present, GEOBIA (Geographic Object-based Image Analysis), heir of OBIA (Object-based Image Analysis), is regarded as an important methodology by object-oriented paradigm for remote sensing, dealing with geo-objects related to image segmentation and classification in the different view point of pixel-based processing. This also helps to directly link to GIS applications. Thus, GEOBIA software is on the booming. The main theme of this study is to look into the applicability of geo-spatial processing open source to GEOBIA. However, there is no few fully featured open source for GEOBIA which needs complicated schemes and algorithms, till It was carried out to implement a preliminary system for GEOBIA running an integrated and user-oriented environment. This work was performed by using various open sources such as OTB or PostgreSQL/PostGIS. Some points are different from the widely-used proprietary GEOBIA software. In this system, geo-objects are not file-based ones, but tightly linked with GIS layers in spatial database management system. The mean shift algorithm with parameters associated with spatial similarities or homogeneities is used for image segmentation. For classification process in this work, tree-based model of hierarchical network composing parent and child nodes is implemented by attribute join in the semi-automatic mode, unlike traditional image-based classification. Of course, this integrated GEOBIA system is on the progressing stage, and further works are necessary. It is expected that this approach helps to develop and to extend new applications such as urban mapping or change detection linked to GIS data sets using GEOBIA.

  • To manage, sort, and grade fishery resources, it is necessary to measure their morphometric characteristics. This labor-intensive task involves performing repetitive operations on land and on a research vessel. To reduce the amount of labor required, a vision-based automatic measurement system (VAMS) for the measurement of morphometric characteristics of flatfish, such as total length (TL), body width (BW), and body height (BH), has been developed as part of a database management system for fishery resources management. This system can also measure the mass (M) of flatfish. In the present study, we describe a morphological image processing algorithm for the measurement of certain characteristics of flatfish. This algorithm, which involves preprocessing, edge pattern matching, and edge point detection, is effective in cases where the flatfish being measured has a deformed tail and is randomly oriented. The satisfactory performance of the proposed algorithm is also demonstrated by means of experiments involving the measurement of the BW, TL and BH of a flatfish when it is straightened (BW : 117mm, TL : 329mm, BH : 24.5mm), when its tail is deformed, and when it is randomly oriented.

  • This study based on the digital innovation of the fashion industry has researched digital-based face design that already has many users all over the world through social media and has influenced the fashion industry. The purpose of this study is to present the future vision of the direction of the fashion industry by classifying representative cases of augmented reality-based digital face design and deriving the oriented value that penetrates them. It was needed to analyzing 3D designer's works that provide digital filter-based face design to the public through Instagram and Facebook. As a result of observing the oriented value of digital face design from the point of view of modern fashion through case exploration, three trends were drawn: experimental formativeness orientation, playful experience orientation, and future technology orientation. This study limited the scope to digital-based face design, but the conclusions presented through these are applicable to all areas of fashion. Therefore, it is supposed to expect to study new phenomena related to fashion design and fashion communication based on digital augmented reality beyond the scope of face design in the future.

  • Aspect Oriented Programming(AOP) is a relatively new programming paradigm and has properties that other programming paradigms don't have. This new programming paradigm provides new modularization of software systems by cross-cutting concerns. In this paper, we propose a regression test method for program evolution by AOP. By using JoinPoint, we can catch a pointcut-name which makes it possible to test the incorrect pointcut strength fault and the incorrect aspect precedence fault. Through extending proof rules to aspect, we can recognize failures to establish expected postconditions faults. We can also trace variables using set() and get() pointcut and test failures to preserve state invariant fault. Using control flow graph, we can test incorrect changes in control dependencies faults. In order to show the correctness of our proposed method, channel management system is implemented and tested by using proposed methods.

  • LED illumination has been developed from simple illumination to human oriented multi-functional system depending on the IT convergence trends. Thus, the convergence of IT technology such as various types of sensor and communication functions with application software can make saving of energy, and there are also several needs about the tailor-made illuminations requirements for the diverse users who want to take their own colors, strengths of the light. For the adaption of these kinds of intelligent system illumination, user oriented sensor and control should be possible. The LED lighting control system transmits and receives data via the Bluetooth mesh network and provides functions such as LED lighting control, LED lighting condition monitoring, energy usage monitoring, and energy peak point management. Therefore, in this paper, we suggest wireless communication platform and control system for the LED illumination control. We can expect life extension of LED illumination, and energy saving through this suggested system.

  • Today linear algebra is one of compulsory courses for university mathematics by virtue of its theoretical fundamentals and fruitful applications. However, a mechanical computation-oriented instruction or a formal concept-oriented instruction is difficult and dull for most students. In this context, how to teach mathematical concepts successfully is a very serious problem. As a solution for this problem, we suggest establishing original concepts in linear algebra from the students' point of view. Any original concept means not only a practical beginning for the historical order and theoretical system but also plays a role of seed which can build most of all the important concepts. Indeed, linear algebra has exactly two original concepts : geometry of planes, spaces and linear equations. The former was investigated in [2], the latter in the present paper.

  • Modern Chinese Literature, the so-called 'feminist' is a very modern and the traditional criticism and took an important position in the double action. Because a woman's freedom from the bondage of traditional ethics of restoring the social status equal to men but to women does not give, that compared to men and women just the dimension of the problem of isolation is not just. It is dominated by yugajeok worldview by streamlining the whole Chinese society to build a modern society and the country was a critical task. However, multi-cultural life of Lin, Hui-yin and Ling, Shu-hua in the history of the world's attention to the shrine was worried attention to soils, rather than East-West dualism law by taking a mixture of both women in modern Chinese literature and Western literature from the center of efforts to overcome the traditional point hayeotdaneun feminist literature that may be different. Lin, Hui-yin and Ling, Shu-hua to overcome the Western-oriented culture really the true dream of China's globalization and localization could be regarded. She naesewotdeon the banner of feminist literature in the traditional 'anti feudal', 'free personality' silcheondoen under such slogans as well as women's liberation from traditional, male-oriented perspective away from the women's unique experiences and new understanding of the value of the superiority the concept of a woman, and was to create. In particular, the femininity of these women who traditionally associated with women and the unique culture - the creation of a new consciousness, a re-evaluation of traditional feminine skills and talents was to try to.

  • In the IoT environment, event data from sensors is continuously reported over time. Event data obtained in this trend is accumulated indefinitely, so a method for efficient analysis and management of data is required. In this study, a data stream segmentation method was proposed to support the effective selection and utilization of event data from sensors that are continuously reported and received. An identifier for identifying the point at which to start the analysis process was selected. By introducing the role of these identifiers, it is possible to clarify what is being analyzed and to reduce data throughput. The identifier for stream segmentation proposed in this study is a semantic-oriented data stream segmentation method based on the event occurrence of each stream. The existence of identifiers in stream processing can be said to be useful in terms of providing efficiency and reducing its costs in a large-volume continuous data inflow environment.
