  • Effect of sodium deoxycholate and sodium dodecyl sulfate on Rhizopus oryzae were investigated. Morphological change was obtained by supplement of these surfactants into culture media during the sumerged culture. In accordance with morphological changes, composition of phospholipid was changed. In case of surfactant-free culture, phosphatidylcholine, phosphatidylethanolamine, and phosphatidylserine were measured more than 95% of total phospholipid. But cardiolipin and phosphatidylinositol were conspicuously increased by treatment of both sufactants. Presence of phospolipase A, C, and D were detected from mycelium. Phospholipase A and D were activated by supplement of sodium deoxycholate and C was activated by sodium dodecyl sulfate. These results were interpreted in respect of polymorphism of phospholipid and membrane stability against solubilization effect of surfactants.

  • This paper describes an approach of composing music with multiple AI composers. This approach enriches more the creativity space of artificial intelligence music composition than using only one composer. This paper presents a simple example with 2 different deep learning composers working together for composing one music. For the experiment, the two composers adopt the same deep learning architecture of an LSTM model trained with different data. The output of a composer is a sequence of notes. Each composer alternatively appends its output to the resulting music which is input to both the composers. Experiments compare different music generated by the proposed multiple composer approach with the traditional one composer approach.

  • The chemical media composition and culture conditions were optimized for mycelial growth of Phellinus igniarius 26005. The method of solid-state fermentation, cultivation of basidiomycetal strains in various grains, was developed. Media composition for optimal growth of Phellinus igniarius 26005 was made of 7.0% malt extract, 0.3% bacto soytone, and 0.2% yeast extract. The optimum condition for mycelial growth was $28^{\circ}C$ and pH 7.0, respectively. For the mass cultivation of mycelia, the hydrated grains with cold water, were put into the plastic bottle. The mycelial growth rate in the bottled grains was high in the early stage with inoculation of homogenized mycelium. The activity of mycelium was maintained by adding sterilized water in the middle of cultivation. The glucosamine content which determins the mycelial growth rate in solid material was in the order of job's tears>barley>black soybean>wheat>malt soybean>brown rice>sorghum>glutinous rice.

  • IoT (Internet of Things) systems are based on heterogeneous hardware systems of different types of devices interconnected each other, ranging from miniaturized and low-power wireless sensor node to cloud servers. These IoT systems composed of heterogeneous hardware utilize data sets collected from a particular set of sensors or control designated actuators when needed using open APIs created through abstraction of devices' resources associated to service applications. However, previously existing IoT services have been usually developed based on vertical platforms, whose sharing and exchange of data is limited within each industry domain, for example, healthcare. Such problem is called 'data silo', and considered one of crucial issues to be solved for the success of establishing IoT ecosystems. Also, IoT services may need to dynamically organize their services according to the change of status of connected devices due to their mobility and dynamic network connectivity. We propose a way of dynamically composing IoT services under the concept of WoT (Web of Things) where heterogeneous devices across different industries are fully integrated into the Web. Our approach allows developers to create IoT services or mash them up in an efficient way using Web objects registered into multiple standardized horizontal IoT platforms where their resources are discoverable and accessible. A Web-based service composition tool is developed to evaluate the practical feasibility of our approach under real-world service development.

  • We have experienced a great deal of change and development in CTS(Computerized Typesetting System) since the prepress market used the phototypesetting machines. The CTS has so many advantages - the shortening of processing time, the versatility of layout, the easy of changing layout style and the absence of pollutional source- as HT(Hot Plate Type) hasn't. Hut, as newspaper is faced with the new circumstances which is the emergence of competitive media and the expansion of economy theory, etc, the newspaper offices have solved the problems using the reduction and closing down of revision department for economizing expense account, the direct composition by editor this paper describes the vital point for direct composition and the design for the descriptive markup-based CTS.

  • Multi-view video has recently gained much attraction from academic and commercial fields because it can deliver the immersive viewing of natural scenes. This paper presents multi-view video processing being composed of intermediate view reconstruction (IVR), graphics composition, and multi-view video viewer. First we generate virtual views between multi-view cameras using depth and texture images of the input videos. Then we mix graphic objects to the generated view images. The multi-view video viewer is developed to examine the reconstructed images and composite images. As well, it can provide users with some special effects of multi-view video. We present experimental results that validate our proposed method and show that graphic objects could become the inalienable part of the multi-view video.

  • Zoogloea ramigera produces an extracellular polysaccharide called zooglan, which adsorbs heavy metals. In the current study, Zoogloea ramigera was cultured in media containing various carbon sources. When different carbon sources were included in the cultivation medium, there was a change in the composition of zooglan that is mainly composed of glucose, galactose, and pyruvic acid. The various zooglan compositions were analyzed by HPLC, and changes in the heavy metal (lead (II) and cadmium) adsorption characteristics relative to a change in the composition were examined using an atomic absorption spectrophotometer. A high adsorption capacity was observed at a pH higher than 3.0. The adsorption of metal ions was the highest at $35^{\circ}C$, and a higher adsorption was obtained with a lower flow rate. Changes in the zooglan composition did result in changes in the heavy metal adsorption characteristics. Furthermore, it was also found that the pyruvic acid content was more important than the glucose or galactose content for heavy metal adsorption.

  • Coworking space is the ideal concept of small companies, freelancers, startups, and entrepreneurs operating out of a shared office space while working independently of one another. The coworkers share the core values of coworking: collaboration, openness, accessibility, sustainability, and community. Little academic research has been completed on the composition of coworking spaces and the businesses that use them. The purpose of this study is to examine the organization and characteristic of coworking space based on domestic and international cases for providing basic data on the coworking space plan. This study examined existing academic literature, media, online sources to assess the environmental background of worldwide coworking space, the current status, conceptualization, and membership plan that can be appled coworking spaces. The case study for coworking space is limited to the space where there is web site that is showed floor plan. Coworking spaces are designed to be environmentally friendly, offering common area with many facilities to encouraging community and collaboration. For creating ideal coworking space, the concept of coworking space must be recognized as a community space for interaction and creativity between people and space. Based on the result of this study, the appropriate zoning, circulation and specific floor plan of coworking space is needed for the next research.

  • 최근 높은 품질의 비디오 서비스에 대한 사용자 요구 증가로 UHD(Ultra High-Definition) 서비스가 등장하였고 여러 방송사에서 UHD 서비스를 제공하기 위해 노력하고 있다. 하지만 아날로그에서 디지털로의 전환이 이루어진지 얼마 지나지 않았고 사용자 대부분은 HD(High-Definition)급 수상기를 가지고 있기 때문에 현재로서는 HD 서비스와 UHD 서비스가 공존해야 하는 상황에 있다. 이를 위해 스케일러블 영상 기술과 차세대 멀티미디어 다중화 전송 표준인 MMT(MPEG Media Transport)가 대두되었다. 사용자 인터페이스로 정의된 MMT CI(Composition Information)를 이용해 계층 부호화 비디오 서비스하려고 하지만 계층 간의 의존성이 높기 때문에 구현상에 어려움이 있다. 이러한 문제점을 해결하기위한 방법으로 본 논문에서는 사용자가 계층 부호화된 비디오 서비스를 제공 받을 수 있는 독립적인 사용자 인터페이스 설계 기법을 제안한다.
