  • 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.

  • 오늘날 '컨버전스'와 '소통'은 모든 분야에서 키워드가 되고 있다. 예술가와 공학자는 새로운 기술에 기반을 둔 협업을 통해 그 동안의 상호단절에서 벗어나 점차 소통하고 있다. 컨버전스 시대에 예술 영역의 인터넷 아트와 기술 영역의 내비게이션과 아이폰에서 오감융합기술의 활용이 돋보인다. 소메라와 미뇨노의 인터넷 아트 $\ll$Riding the Net$\gg$, $\ll$The Living Room$\gg$, $\ll$The Living Web$\gg$은 음성인식을 통한 시각이미지와 촉각을 통한 시 공간 표현을 인터넷과 오감융합기술을 통해 구현하고 있다. 그리고 산업기술에서 내비게이션과 아이폰은 음성인식을 통한 오감융합기술을 적용하여 감성영역을 확장하여 인터넷 아트와 비슷한 기술을 선보인다. 이 연구에서 살펴본 바와 같이, 예술과 기술의 융합적 발전은 디지털 아트와 문화기술 산업의 새로운 지평을 열 것으로 보인다.

  • 본 연구의 목적은 아트메이크업과 초현실주의의 이론적 배경을 보다 심층적으로 살펴보고 초현실주의 데페이즈망에 근거한 창의적인 사고와 발상을 미술과 메이크업이 접목된 아트메이크업의 다양한 표현방식을 재조명하는데 있다. 연구방법은 선행연구와 전문서적, 인터넷 등을 토대로 초현실주의 데페이즈망 개념과 기법, 아트메이크업에 관한 이론적 배경을 이론적으로 고찰한 후 데페이즈망 기법의 특성을 이중적 이미지, 이질적 사물의 결합, 변형 및 변환, 공간의 변조로 분류하여 총 4작품을 제작한다. 이러한 연구 결과는 첫째, 미술과 메이크업의 접목을 통해 창의성을 기반으로 하는 표현영역을 창출해내어 미술과 메이크업분야가 서로 융합 활용될 수 있는 기반을 마련하였다. 둘째, 전혀 다른 공간에서 이미지를 창출해 내어 결합함으로써 보는 이들에게 신선함과 낯섦을 제공한다. 이로서 본 연구자는 창의적인 아이디어를 도출해내어 표현영역을 넓힐 수 있도록 방향성을 제시하였으며 아트메이크업이 단순히 미적수단에서 그치는 것이 아니라 예술의 한 장르로 자리매김하기를 기대해본다.

  • 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.
