iA-Canvas is HMI program which is the industrial automation application developed based on the Java language, and can run on any OS such as Windows, UNIX, Linux. The iA-Canvas is built on object-oriented open structure and consider network functionality and user experience as a system of centralized management and distributed management. iA-Canvas is composed of several components such as Builder, IO Server, Viewer, and Web Service Module and provides a GUI control environment. This paper explains design and implementation of iA-Canvas that is a tool for development of integrated management system, and shows practical examples of integrated management system that use iA-Canvas.

In this paper, we propose CANVAS (Creative ANalytics enVironment And System), an analytics system of the National Research Data Platform (DataON). CANVAS is a personalized analytics cloud service for researchers who need computing resources and tools for research data analysis. CANVAS is designed in consideration of scalability based on micro-services architecture and was built on top of open-source software such as eGovernment Standard framework (Spring framework), Kubernetes, and JupyterLab. The built system provides personalized analytics environments to multiple users, enabling high-speed and large-capacity analysis by utilizing high-performance cloud infrastructure (CPU/GPU). More specifically, modeling and processing data is possible in JupyterLab or GUI workflow environment. Since CANVAS shares data with DataON, the research data registered by users or downloaded data can be directly processed in the CANVAS. As a result, CANVAS enhances the convenience of data analysis for users in DataON and contributes to the sharing and utilization of research data.

In order to investigate the shearing efficiency of the Danish sein net using in the sea area of korea, the autors carried out a models of prototype net, and the nets on which the canvas attached to the rear part of the square and to the extension wing of the prototype net, respectively. The model net is made of scale of 1/35 according to Tauti's Law of similarity on fishing gear. The result obtained are as follows: 1. The hydrodynamic resistance increased the maximum 30% in case of the canvas attached to the square, and decreased the maximum 35% in case of the canvas attached to the extension wing in comparison with prototype net. 2. The height of net mouth increased the maximum 12% in case of the canvas attached to the square, and decreased the maximum 5.8% in case of the canvas attached to the extension wing in comparison with prototype net. 3. The width of net mouth decreased the maximum 4% in case of the canvas attached to the square, and increased the maximum 8.4% in case of the canvas attached to the extension wing in comparison with prototype net. 4. The projective area of net mouth increased the maximum 13.6% in case of the canvas attached to the square and increased the maximum 11.8% in case of the canvas attached to she extension wing in comparison prototype net.

Recently, it is not sufficient that contemporary firms satisfy customers to be really successful, they must create new value. To do so, many firms focus on the blue ocean strategy. The blue ocean strategy proposed the strategic canvas as a main tool for identifying the opportunities for value differentiation. It is easy to understand and for the use, but has weakness that is a unclear procedure to make it done. To complement its weak point, this study proposes a refined strategic canvas based on the concept of the business evolution that comes from a discontinuous evolution trend of 5 stages known as customer expectation.

A vast amount of research has been carried out for executing compute-intensive applications on resource-constrained mobile devices. Computation offloading is a method in which heavy computations are dynamically migrated from a mobile device to a server, exploiting the powerful hardware of the server to perform complex computations. An important issue for offloading is the complexity of reconciling the execution state of applications between the server and the client. To address this issue, snapshot-based offloading has recently been proposed, which utilizes the snapshot of a web app as the portable description of the execution state. However, for web applications using the HTML5 canvas, snapshot-based offloading does not function correctly, because the snapshot cannot capture the state of the canvas. In this paper, we propose a code generation technique to save the canvas state as part of a snapshot, so that the snapshot-based offloading can be applied to web applications using the canvas.

The purpose of this study is to seek ways to enhance sustainability by understanding the business model of social ventures that should be accompanied by social and environmental missions as well as economic missions. To achieve this purpose, We seek to enhance sustainability by analyzing the business model of social venture entrepreneurs. The analysis tool used TLBMC (Triple Layered Business Model Canvas). It is extended from a business model canvas that is widely utilized and recognized in economical terms. The TLBMC is proposed by Alexandre & Raymond (2016) to help achieve a holistic view with horizontal and vertical associations. Based on the TLBMC, we found that each of the social ventures needed additional factors or unnecessary factors, and that they were approaching a different meaning from the beginning to stabilizing phase. And social entrepreneurs have concluded that using TLBMC to provide stakeholder and staff basic understanding of economic, social, environmental and environmental factors, enabling rapid and accurate communication and collaboration. This study will help people who prepare and study social ventures to have economic, environmental, and social perspectives. t could also be used to redefine the direction and value of entrepreneurs operating social ventures, such as vision and mission to help clarify the roles of the organization.

An active stimulating method for juvenile fishes to drive escaping from mesh of the codend was examined by shaking canvas in the bottom trawl followed by shrimp beam trawl. Field fishing trials by a bottom trawl were carried out between the Geomoondo and Jejudo in west of South sea, Korea by conver-net methods to examine the effect on the reduction of juvenile fish as a discard catch by generating a shaking movement of the codend using two pieces of asymmetrical semi-circular canvas. The mean period of the shaking motion with the round canvas was 10-15 s, and the range of amplitude as a vertical depth change was up to 0.4-0.6 m when towing speed 3.4-4.3 k't as estimated by peak event analysis. The escape rate of juvenile fish in conver-net by total juvenile bycatch (codend and cover-net) in 14 trials increased from 20% in a steady codend to 34% using a shaking codend in the bottom trawl, while the marketing catch or total bycatch was similar between steady and shaking cod ends. There was no difference in the body size of the fish and species composition between the steady and shaking cod ends. Above results demonstrate a new method for bycatch reduction actually up to 18% using an active stimulating device, although further experiments are needed to increase an effective shaking motion of the codend in amplitude and period for more bycatch reduction.

An active stimulating device, such as a fluttering net or canvas attached to the end of a cod end generating a shaking motion, could help to encourage the escape of juvenile fish positioned passively near the net. Field fishing trials using a shrimp beam trawl were carried out to examine the effect on the reduction of juvenile fish or other discard catch by generating a shaking movement of the cod end using an unbiased cap-like round canvas. The mean period of the shaking motion with the round canvas was ~14 s, and the mean amplitude was 0.4 m as measured by peak event analysis and the global wavelet method. The bycatch of juvenile fish in 14 trials decreased by ~30% and by ~25% using a steady cod end for the total bycatch using a shaking cod end in the shrimp beam trawl, while the marketing catch was similar between steady and shaking cod ends. There was no difference in the body size of the shrimp or fish and species composition between the steady and shaking cod ends. Above results demonstrate a new method for bycatch reduction using an active stimulating device, although more detailed studies are needed.
