IoT 환경에서 센싱 정보의 활용을 위해서는 센서로 부터 생성된 정보의 가공 및 처리를 위한 효율적인 소프트웨어 아키텍처 설계가 필수적이다. 특히 IoT 환경에서 사물은 인터넷에 연결되고 각종 센서를 탑재한 디바이스간 통신이 가능하여야 한다. 그러나 MapReduce 기반의 Hadoop과 Twister은 데이터의 배치 처리에 적합하지만, 스트리밍 센서 자료의 이동중 처리에는 제약점을 갖는다. 전통적인 스트리밍 데이터 처리 방법인 MOM 기반의 메시지 큐 시스템을 이용해 메시지 스트림을 처리하는 방식은 프로그래머가 메시지 흐름의 복잡도를 고려해야 상세한 처리를 프로그램 함으로써 유지보수 및 확장성을 갖기 어려움이 있다. 이 논문에서는 IoT 환경에서 수집된 센싱 자료의 처리를 위한 소프트 웨어 아키텍처를 설계하였다. 또한 설계된 소프트아키텍처를 기반으로 오픈소스 프레임워크인 Storm의 응용 구성을 기술한다. 구성응용은 센서게이트웨이(Sensor Gateway)를 통해 자료를 수집한 후 실시간 스트리밍 데이터를 파이프-필터 스타일로서 변환한다.

Scribble methodology is developed from the modernist's effort of pursuing the free expression and painterlyness And in modernism period usual abstract mode is made by simple plastic ingredients. One of them is Scribble way. In the period of postmodern, the Scribbling is confused with destructive methodology like Iconoclasm, Vandalism and scribbling. Lucio Fontana and Robert Raushenberg had developed these methodology and made new direction in $1960\sim1970$. After 1980, there had been graffiti movement similar to scribbling in germany. There had been developed many kind of scribble methodology, in each artist and be prolonged destroy the price of our usual concept. These Styles are able to discerned as follows. Firstly, in case of Cy Twombly, he used very allusive signifier, which contain different motives come from the ancient ruins or myths. The methodology follows multi-codified meaning relationship. Secondly, the methodology was developed by Jean Michael Basquait as the type of Hispanic scribbling for ebony peoples and by Keith Harring as the type of Cartoon image of Mass-media based on technology. Thirdly, the multi-meaning style was developed by David Salle as the type of destructive methodology which are the ambivalent images conjoined difference time and term and by Gigmar Polke as the type of mixture of abstract and realistic shapes together which are based on the aesthetics which is based on pessimistic sight for contemporary civilization. It means the methodology is based on the multi-codification of postmodern semiotics. So the scribbling mode is subjected as important as the changedness of late 20th century painting developments.

The purpose of this study is to form a calculation formula of the mean skin temperature on the human body in a heated room by the use of floor heating system. Korean traditional floor heating system is a long way from being defunct. The floor heating systems based on hot water have been coming into wide use mainly in the apartment house. However, it is considered that the design process and evaluation method for the floor heating systems in the standpoint of human being are not established so far. In the floor heating systems, air temperature as well as floor temperature should be considered as physical factors which affect the sensation of human body. Furthermore, extremely few studies have been performed on the sitting with legs crossed posture sedentary which is the typical dwelling life style of residents from the ancient times in Korea, while a large number of studies on the influence of the floor heating systems on the human body in standing and sitting on a chair sedentary have been carried out. Especially, it is essential to elucidate how mean skin temperature on the human body is affected by thermal conduction in the contact area between the sitting with legs crossed posture sedentary human body and floor including thermal radiation due to the combination of air temperature and floor temperature, but the studies dealt with such issues have hardly been performed. Based on the above statements, the influence of the environment condition due to the combination of air temperature and floor temperature is discussed in the present investigation through theoretical of mean skin temperature on the human body in the floor heating systems.

This paper presents some quasi-static tests for 4 mixed columns composed of CFST column and RC column. The seismic performance and failure mode were studied under low-cyclic revised loading. The failure mode was observed under different axial compression ratios. The hysteretic curve and skeleton curve were obtained. The effects of axial compression ratio on yield mechanism, displacement ductility, energy dissipation, stiffness and strength attenuation were analyzed. The results indicate that the failure behavior of CFST-RC mixed column with archaized style is mainly caused by bending failure and accompanied by some shear failure. The axial compression ratio performs a control function on the yielding order of the upper and lower columns. The yielding mechanism has a great influence on the ductility and energy dissipation capacity of specimens. Based on the experiment, finite element analysis was made to further research the seismic performance by ABAQUS software. The variable parameters were stiffness ratio of upper and lower columns, axial compression ratio, yielding strength of steel tube, concrete strength and rebar ratio. The simulation results show that with the increase of stiffness ratio of the upper and lower columns, the bearing capacity and ductility of specimens can correspondingly increase. As the axial compression ratio increases, the ductility of the specimen decreases gradually. The other three parameters both have positive effect on the bearing capacity but have negative effect on the ductility. The results can provide reference for the design and engineering application of mixed column consisted of CFST-RC in Chinese archaized buildings.

Purpose: University students happen to be in a transitional period at the beginning of one's adult life and thereby establish the basis for their health care. The negative lifestyles followed by students during this period can also affect their reproductive health. The purpose of this study was to identify lifestyle, reproductive health, gender differences and relationships between lifestyle and reproductive health in university students. Methods: We used a descriptive cross-sectional design. A total of 300 subjects were enrolled. Data were collected using structured questionnaires between October 11 and 25, 2017 and analyzed using SPSS 25.0. Subjects agreed to undergo a face-to-face interview, including administration of the Health Promotion Lifestyle Profile II (HPLP-II) and reproductive health (knowledge, attitude, and behaviors). Results: The mean age of the subjects was 21.4 years. HPLP-II and reproductive health behaviors were significantly different between the genders. The scores of physical activity and nutrition in females were significantly lower than males. The scores of safe sex and sexual responsibility in females were significantly higher than males, and the score of genital health management was significantly lower in females than males. High HPLP-II score was observed to be in correlation with high reproductive health attitudes and behaviors. Conclusion: The result revealed differences in lifestyle and reproductive health between both the genders. For improvement of reproductive health of university students, provision of lifestyle intervention including healthy nutritional habits and physical activity is imperative.

시대정신을 함유하고 사회와 역사를 통해 인간을 고찰하며 삶과 현 세대를 자각케 하는 예술적 완성도가 높은 영화의 구성과 상징표현 그리고 스타일 등을 분석하여 그 내적 의미와 철학의 표현을 분석하는 것은 대중예술로서 영화에 있어 매우 뜻 깊으며 가치 있는 연구 일 것이다. 영화 로마는 절제하고 감추고 생략함으로써 대중들의 마음 속 빈틈을 파고들고 절제되었으며, 흑백영화로써 색감도 감췄다. 인종, 자본, 사회적으로 억압된 역사와 가정부로 살아가는 일상의 아이러니한 메시지를 표현하는 상징적 이미지를 통한 미학적 시도를 많이 발견할 수 있다. 많은 대조를 통한 상징적 표현과 사물을 통한 상징적 표현을 영화 속에 그려내며 자신만의 작가주의적인 영상언어를 구사하고 있음을 알 수 있다. 이러한 예술적 가치를 함유한 상업 영화의 분석은 예술영화의 나아갈 바에 대한 척도와 작가주의적 표현기법의 선례로 향후 작품 제작에 있어 도움을 줄 것으로 기대된다.

Hangang Artpark construction is an enterprise founded in 2018 that involved installing public artworks created by 37 different people (teams) in Hangang Park located in Yeouido and Ichon Park. An iconic public space in Seoul, Hangang Park is turning into an even better public space due to the efforts to change the park into an eco-friendly, cultural-artistic space in tandem with the change in times. The objective of the Hangang Artpark construction business is to augment the environmental and scenic value of Hangang not only to provide a space for leisurely activities but also to revive it as a cultural-artistic area. This is a study of the concept and the design and installation processes of "Thinking of each other", a project by the Hangang Artpark construction business. This art piece has been installed in the wetlands and it trails along Ichon Hangang Park, which was created during the environmental recovery project. The piece consists of sculptures molded into animal shapes that are unique to the location and ecology of the area, displayed in harmony with the park's street furniture. By showing the coexistence of animals that existed in Hangang in the past along with the current inhabitants and the natural enemies of these inhabitants, the piece displays an ecofriendly scene. Moreover, by incorporating this piece into the street facilities of the park, such as gazebos, streetlights, surveillance cameras, and perches, the piece exhibits a different kind of street view compared to the installation style of other conventional environmental artworks. The various sculptures are installed along with the street facilities throughout the trail, rather than in a specific location intended for artworks, thereby achieving harmony with the park scene. In so doing, the piece elicits in the beholder an environment-friendly way of thinking, and at the same time, gives them a sense of calm and pleasure. Further, the paper researches the methods of safely installing art pieces in public spaces and of maintaining these installations.
