  • This paper represents the multiple sensor fusion algorithm for the deep-sea unmanned underwater vehicles (UUV), composed of a remotely operated vehicle (ROV) 'Hemire' and a depressor 'Henuvy'. The performance of underwater positioning system usually highly depend on that of acoustic sensors such as ultra short base line(USBL), long base line(LBL) and altimeter. A practical sensor fusion algorithm is proposed in the sense of a moving window concept. The performance of the proposed algorithm can be observed by applying the algorithm to the Hemire sea trial data which was measured at the East Sea.

  • Unmanned Aerial Vehicles(UAVs) require collision avoidance capabilities equivalent to the capabilities of manned aircraft to enter the airspace of manned aircraft. In the case of Visual Flight Rules of manned aircraft, collision avoidance is performed by 'See-and-Avoid' of pilots. To obtain those capabilities of UAVs named as 'Sense-and-Avoid', sensor-system-based intruder tracking and collision avoidance methods are required. In this study, a multi-sensor-based tracking, data fusion, and collision avoidance algorithm is designed by using a model-based design tool MATLAB/SIMULINK, and validations of the designed model and code using numerical simulations and processor-in-the-loop simulations are performed.

  • Sensor networks consist of sensor nodes with small-size, low-cost, low-power, and multi-functions to sense, to process and to communicate. Minimizing power consumption of sensors is an important issue in sensor networks due to limited power in sensor networks. Clustering is an efficient way to reduce data flow in sensor networks and to maintain less routing information. In this paper, we propose a multi-hop clustering mechanism using global and local ID to reduce transmission power consumption and an efficient routing method for improved data fusion and transmission.

  • This study was conducted to identify college students' supportive attitude toward the elderly and their awareness of the socialization of care for the elderly, since they will have the responsibility for and the support of the aged society in the near future. This study was also conducted to analyze the factors which affect the socialization of elderly care, and to contribute to building a care system which promotes ahealthy and happy lifestyle for the elderly. After conducting a survey of 1,100 students from13 universities around the entire country, I have analyzed 1,089 data forms, and omitted 11 data entries which had errors or were not answered. 1. Those surveyed are 1,089 students from 13 universities around the entire country. Regional distributions are as follows : 263 students from 4 universities in Daegu and Kyongsangbuk Do(24.2%), 291 students from 3 universities in Busan and Kyongsangnam Do(26.7%), 272 students from 2 universities in Jeolla Do(25.0%), 263 students from 4 universities in Seoul and Gyeonggi Do. Males are 51.7% and females are 48.3% of these students. 2. Instrumental supportive sense level is high in men and emotional supportive sense level is higher in women. Also emotional supportive sense is higher in groups of those having more family members and coming from agricultural regions. 3. The sense of living with aged parents is higher in those living with grandparents than those living separate. The sense of living with sons and daughters after aging is stronger in the students from the Science and Engineering Departments than in the Social and Human Sciences Departments; also higher for men than women. 4. Recognition of elderly care socialization is higher in those from Social and Human Sciences Departments than from Science and Engineering Departments; higher in the case of upper classmenand aged groups, groups having fewer family members than more family members, and in the case of living separated from grandparents. 5. The factors affecting the sense of living with grandparents were family cohesion and instrumental supportive sense. The factors affecting the sense of elderly care socialization were family cohesion, instrumental supportive sense, and emotional supportive sense. From the results it is concluded that to insure a healthy and happy lifestyle for aged people, elderly care socialization offered by society and the country must provide desirable, appropriate care services based on the centralized support system of the family. In order to do this, we propose that elderly care needs inter-family and inter-generational fusion programs to improve family cohesion and care recognition. Also, elderly care is in urgent need to build a strong Family and Health Welfare System for care socialization.

  • Recently 'convergence' and 'communication' have been keywords in many areas. Artists and engineers have begun to communicate each other through collaboration based on new technologies. One of the exemplary technologies of this era of convergence is a technology of fusing five senses used by both Internet Art and industrial technologies such as car navigation systems and the iPhone. Sommerer and Mignonneau's Internet Art $\ll$Riding the Net$\gg$,$\ll$The Living Room$\gg$, and $\ll$The Living Web$\gg$ implement the Internet and the five-sense fusion technology to translate not only sound into visual images but also tactile senses into tempo-spatial representations. Likewise, industrial technologies such as car navigation systems and the iPhone employ the five-sense fusion technology of speech recognition, which leads to the expansion of the realm of senses in technology as seen in Internet Art. As examined in this study, the development of art and technology through their convergence will open up a new dimension of digital art and culture technology industry.

  • The purpose of this study is to examine the theoretical background of art make-up and surrealism in depth and shed new light on creative thoughts coming through application of Depaysement and various kinds of expression realized through art make-up, where art and make-up are incorporated. The study method is to conduct prior research followed by a theoretical study of the concept and techniques of Surrealistic Depaysement and theoretical background of art make-up through specialized books and internet sources and then to create 4 artworks representing characteristics of Depaysement technique categorized in dual image, fusion of heterogeneous objects, modification and conversion, and change of space. This examination resulted in first, a foundational ground for fusion and use of art and make-up sectors by creating a realm of expression based on creativity through incorporation of art and makeup and second, a sense of freshness and unfamiliar-ness by creation of an image in a completely unfamiliar space. Therefore, the researcher sets a direction for ways to come up with new ideas and expand the realm of expression and hopes that the art-makeup does not just become an aesthetic tool but turn itself as an art genre.

  • This study reveals the aesthetic characteristics and formative characteristics of the converged images of romantic sportism by analyzing how sportism fashion and romantic images fuse together. As for research methods, this study examines the aesthetic and formative characteristics of sportism fashion and the aesthetic and formative characteristics of romantic styles after grasping the basic concept and background based on a literature study of romantic and sportism fashion. As for an empirical study, the styles of sportism fashion pictures of romantic images collected from 2010 S/S to 2016 S/S from www.vogue.com were analyzed. The study results showed that there are 4 aesthetic characteristics of romantic sportism in modern fashion that included 'non-oriented form visibility', 'non-boundary sensibility', 'multi-sense blend', and 'non-formal mixed usage'. The formative characteristics based on these aesthetic characteristics are also derived in accordance with design factors as well as analyzed through representative pictures.

  • An allocation of sensing and reporting times is proposed to improve the sensing performance by scheduling them in an efficient way for cognitive radio networks with cluster-based cooperative spectrum sensing. In the conventional cooperative sensing scheme, all secondary users (SUs) detect the primary user (PU) signal to check the availability of the spectrum during a fixed sensing time slot. The sensing results from the SUs are reported to cluster heads (CHs) during the reporting time slots of the SUs and the CHs forward them to a fusion center (FC) during the reporting time slots of the CHs through the common control channels for the global decision, respectively. However, the delivery of the local decision from SUs and CHs to a CH and FC requires a time which does not contribute to the performance of spectrum sensing and system throughput. In this paper, a super-allocation technique, which merges reporting time slots of SUs and CHs to sensing time slots of SUs by re-scheduling the reporting time slots, has been proposed to sense the spectrum more accurately. In this regard, SUs in each cluster can obtain a longer sensing duration depending on their reporting order and their clusters except for the first SU belonged to the first cluster. The proposed scheme, therefore, can achieve better sensing performance under -28 dB to -10 dB environments and will thus reduce reporting overhead.

  • The purposes of this study were to arrange and analyze the Oriental Mode in 20th century fashion and to clarify that Oriental dress and its ornaments appearing as the main subject of Occident fashion gradually The results were as follows : First, Oriental Mode in 1900-1950s was prescribed as the 'Orientalism' to be expressed Occidental imperialistic viewpoint. Therefore, the Orient was used as the simple recording mark of the imperialism product or commercial motive and it was reflected in fashion. Second, it was explained in 1960-1970s as the 'Folklore Orientalism' that focus was moved into the folklore costume of Orient. Third, in 1980s, 'Ethnic' was conspicuous that reflected the traditional costume in the area of non-christianity. Especially, it was the decade that the Middle East attracted attention. Fourth, Oriental Mode in 1990s appeared as the 'Fusion' that Oriental and Occidental elements were mixed and compromised on equal terms. Fifth, it was expressed as a word 'Zen' that had natural fiber, moderate color and silhouette to be most basic and concise about human body at the end of 1990s. This study could confirm that the center of fashion was being converted into the Orient gradually. This may be understood as the pluralistic culture phenomenon. Namely, eclectic principle to recognize mutual style and individualistic nature and to utilize and mix was made, and this brought the conversion into Oriental sense of value.
