Calligraphy contents(shortly called, CalliContents) depict the feature of communication media with artistic sentences or drawings before being processed into digital contents to become printed advertisement, visual design and entertainment products. As a fast growing business model, they can be applied to every single scope of all fields these days and each application case presented excellent effects to grab consumers' attention immediately. In this paper, we designed and produced an emotional bi-directional recommendation DIY calligraphy contents platform to consume created cultural contents and boost personalized contents industry that meets consumer's needs through both wired and wireless-based software with convergence of artistic and emotional calligraphy contents and ICT. For this works, we established for DIY calligraphy consumers a foundation of a virtuous circle of the CalliContents where various CalliContents are provided in on and offline environment and a third party target is opened at the CalliContents platform

With the rapid development of deep learning and artificial intelligence, generative models have achieved remarkable success in the field of image generation. By combining the stable diffusion method with Web UI technology, a novel solution is provided for the application of AI painting generation. The application prospects of this technology are very broad and can be applied to multiple fields, such as digital art, concept design, game development, and more. Furthermore, the platform based on Web UI facilitates user operations, making the technology more easily applicable to practical scenarios. This paper introduces the basic principles of Stable Diffusion Web UI technology. This technique utilizes the stability of diffusion processes to improve the output quality of generative models. By gradually introducing noise during the generation process, the model can generate smoother and more coherent images. Additionally, the analysis of different model types and applications within Stable Diffusion Web UI provides creators with a more comprehensive understanding, offering valuable insights for fields such as artistic creation and design.

최근 일반인을 위해 악기를 다루지 못하더라도 앱이나 웹에서 마치 놀이를 하듯이 연주하는 방법이 각광받고 있다. 그 이유는 자연스러운 우연성(randomness)의 연주 형태를 지니고 있기 때문이라고 판단된다. 따라서 관조적 관람객을 유인시키고 능동적으로 변화시키는 '우연 작동법'을 런치패드를 활용하여 이론적 배경과 사례분석을 통해 영상시스템을 개발, 제시하였다. 스텝시켄서 개발은 외부 프로그램으로 연결시켜 영상시스템을 스텝시켄서로 구현하는 방법과 모션 클립(Clip)들로 만들어 런치패드의 키(Key)마다 배치하여 실행시키는 키보드 런치형으로 구분하여 2가지 타입으로 개발하였으며, 최종 영상시스템을 통해 파생된 최적화 문제점과 해결책을 제시하였다.

As the mobile devices have powerful CPUs and memories, it is possible to carry the large volumes of design drawings, such as DXF files, on mobile devices. However, since the format of a DXF file is the ASCII, it has the shortcoming where the size of a file is larger than a binary formatted file and it is difficult to display the entities of drawings quickly on mobile devices. In this paper, we design the DXF manager system on a smart phone. To speed up the rate of the display and panning, the DXF manager hires the spatial index, the fixed grid file. We also implement the system on the Samsung Omnia-1$^{(R)}$ to exploit the Windows Mobile$^{(R)}$ operating system.

본 논문은 유니버설 디자인 원칙을 바탕으로 키오스크의 사용성을 높여 모든 사용자가 편리하게 사용하기 위한 키오스크 디자인 개선 방향을 연구하는 것이 목적이다. 키오스크 사용과 관련한 나이별 설문조사와 분석결과를 검증하는 추가 설문조사를 통해 필수 개선점을 도출하여 디자인 개선 방향을 연구하였다. 연구결과는 다음과 같다. 키오스크 화면 배경과 디자인 요소 간 높은 대비, yellow 계열의 색상, 아웃라인화 한 디자인 요소의 사용으로 가독성을 높인다. 그리고 10pt를 기준으로 폰트의 축소와 확대가 가능하도록 한다. 또한, 휠체어 탑승자를 고려하여 하단부 설계가 불가능한 영역과 키오스크가 낮추어져야 할 최소 높이를 도출하였다. 향후 키오스크 디자인 시에는 개인의 특성에 따라 키오스크의 기능이 다변화할 수 있도록 하는 디자인과 시스템이 필요하며 유니버설 디자인의 적용에 중점을 두어 디자인해야 한다. 본 연구는 연구대상이 한정적이므로 다양한 표본을 대상으로 한 추후 연구가 필요하며 색상과 가독성에 관련한 검증 연구도 추후 진행할 계획이다.

In this paper, we determined the driver's stress and fatigue level through physiological signals of a driver in the connected car environment, accordingly designing and implementing the architecture of the connected cars' platforms needed to provide services to make the driving environments comfortable and reduce the driver's fatigue level. It includes a gateway between AVN and ECU for the vehicle control, a framework for native applications and web applications based on AVN, and a sensing device and an emotion estimation engine for application services. This paper will provide the element technologies for the connected car-based convergence services and their implementation methods, and reference models for the service design.

The objective of this study is to investigate patent trends of Daegu city which tries to introduce environment friendly energy and to develop new technology or new industry sprung from technology convergence on smart decentralized energy technology and other technologies. After applying network analysis to corresponding groups of technology or industry convergence, strategy for future energy convergence industry is provided. Patent data applied in Daegu city area are used to obtain research goal. The technology which contains several IPC codes (IPC Co-occurrence) is considered as a convergence technology. Path finder network analysis is used for visualizing and grouping by using IPC codes. The analysis results categorized 13 groups in energy convergence industry and reclassified them into 3 cluster groups (Smart Energy Product Production Technology Group, Smart Energy Convergence Supply Technology Group, Smart Energy Indirect Application Technology Group) considering the technical characteristics and policy direction. Also, energy industry has evolved rapidly by technological convergence with other industries. Especially, it has been converged with IT industry, and there is a trend that energy industry will be converged with service industry and manufacturing industry such as textile, automobile parts, mechanics, and logistics by employing infrastructure as well as network. Based on the research results on core patent technology, convergence technology and inter-industry analysis, the direction of core technology research and development as well as evolution on decentralized energy industry is identified. By using research design and methodology in this study, the trend of convergence technology is investigated based on objective data (patent data). Above all, we can easily confirm the core technology in the local industry by analyzing the industrial competitiveness in the macro level. Based on this, we can identify convergence industry and technology by performing the technological convergence analysis in the micro level.

Many distributed applications build overlays on top of the Internet. Several unsolved issues at the network layer can explain this trend to implement network services such as multicast, mobility, and security at the application layer. On one hand, overlays creating basic topologies are usually limited in flexibility and scalability. On the other hand, overlays creating complex topologies require some form of application level addressing, routing, and naming mechanisms. Our aim is to design an efficient and robust addressing, routing, and naming infrastructure for these complex overlays. Our only assumption is that they are deployed over the Internet topology. Applications that use our middleware will be relieved from managing their own overlay topologies. Our infrastructure is based on the separation of the naming and the addressing planes and provides a convergence plane for the current heterogeneous Internet environment. To implement this property, we have designed a scalable distributed k-resilient name to address binding system. This paper describes the design of our overlay infrastructure and presents performance results concerning its routing scalability, its path inflation efficiency and its resilience to network dynamics.
