IEC1131-3 Specification of Programming Controller is established in 1994 and consists of 3 graphical languages and 2 textual languages. It is used in PLC and small scale controller because of its uniformity and extensibility. This paper describes Soft Logic Designer which is a graphical and textual programming editor for IEC1131-3 programming languages. Soft Logic Designer is developed with Object Orient Language, C++ under Microsoft Windows 95. It has two graphic editors for Sequential Function Chart and Function Block Diagram and one textual editor for Structured Text. Users can efficiently write high-level programs with mouse and menu buttons.

Document summarization is an important task in various areas where the goal is to select a few the most descriptive sentences from a given document as a succinct summary. Even without training data of human labeled summaries, there has been several interesting existing work in the literature that yields reasonable performance. In this paper, within the same unsupervised learning setup, we propose a more principled learning framework for the document summarization task. Specifically we formulate an optimization problem that expresses the requirements of both faithful preservation of the document contents and the summary length constraint. We circumvent the difficult integer programming originating from binary sentence selection via continuous relaxation and the low entropy penalization. We also suggest an efficient convex-concave optimization solver algorithm that guarantees to improve the original objective at every iteration. For several document datasets, we demonstrate that the proposed learning algorithm significantly outperforms the existing approaches.

프로그래밍 언어 교육에서 일반적으로 학습자들은 블록 기반 프로그래밍 언어에서 텍스트 기반 프로그래밍 언어 순서로 학습한다. 블록 기반 프로그래밍 언어나 텍스트 기반 프로그래밍 언어는 여타의 프로그래밍 언어들과 마찬가지로 프로그래밍의 기본 논리는 동일하나, 형태, 언어적 특성 및 사용 등에 대하여 다소 차이가 있다. 따라서 본 연구에서는 학습자들의 블록 기반 프로그래밍 언어에서 텍스트 기반 프로그래밍 언어로의 유연한 학습 전이를 돕기 위한 프로그램의 설계 방안을 선행 조직자의 제시, 학습 콘텐츠의 체계화, 단순하고 직관적인 화면 구성으로 제시하였다.

The purpose of this research is to investigate Korean popular attitudes and social perceptions of 'sharing economy' terminology at the current moment from a creative or socio-economic point of view. In Korea, this study discovers and interprets the objective and tangible annual changes and patterns of sociocultural collective intelligence that have taken place over the last five years by applying text mining in the big data analysis approach. By crawling and Googling, this study collected a significant amount of time series web meta-data with regard to the theme of the sharing economy on the world wide web from 2010 to 2014. Consequently, huge amounts of raw data concerning sharing economy are processed into the value-added meaningful 'word clouding' form of graphs or figures by using the function of word clouding with R programming. Till now, the lack of accumulated data or collective intelligence about sharing economy notwithstanding, it is worth nothing that this study carried out preliminary research on conducting a time-series big data analysis from the perspective of knowledge management and processing. Thus, the results of this study can be utilized as fundamental data to help understand the academic and industrial aspects of future sharing economy-related markets or consumer behavior.

In the areas of CAE, CAD and CAO integration & automation technology, the word 'File Wrapping' means a virtualization of TEXT files that supports variables-based I/Os like variable assignments in programming languages. This File Wrapping process is one of the cornerstones of CAE, CAD and GAO integration & automation, and the performance of File Wrapping process, which is depending on the sire of a TEXT file to be accessed and the number of regions and their distribution, has a critical effect on the total performance of the CAE, CAD and CAO integration & automation systems. In this paper, we define TEXT File Region Management which generalizes the main functions of the File Wrapping process, and describe a prototype of TEXT file Region Management which is implemented as a Grid service. After that, the validity of the proposed model and the TEXT File Region Management service are discussed with evaluation results of the prototype.

In the previous research, we proposed a Kinetic typography font engine that can easily add motion to text with function call only. However, since it is aimed at constructing movements for a sentence, there is still inconvenience in the production of various kinetic typography motions in word or letter unit. We propose Kinetic Typical Extended Motion API(Application Programming Interface) that extends Kinetic Motion API. The extended Kinetic Typographic Font Engine aims to simplify the process of making kinetic typography in words and letters, including the kinetic typographic motion library provided as a function. In addition, various applications that can apply Kinetic typography A kinetic typography authoring interface is provided for facilitating the construction of a motion library for the robot.

There is a method to analyze the big data of the article and text mining by using Python language. And Python is a kind of programming language and it is easy to operating. Reaserch and use Python to creat a Web environment that the research result of the analysis can show directly on the browser. In this thesis, there are 100 article paper frrom Altmetric, Altmetric tracks a range of sources to capture. It is necessary to collect and analyze the big data use an effictive method, After the result coming out, Use Python wordcloud to make a directive image that can show the highest frequency of words.

Chatting room has become widely using technology and it is vulnerable to the internet attackers. We proposed a chatting system using a Purebasic programming language to communicate across networks system. Chatting room text is a form of instant messaging between two or group of people. A Communication experiment was designed and implemented to confirm the validity of the developed chatting system on a trusted platform.

In this paper, we study improvement of web accessibility of Korean Internet shopping mall websites. First, we analyze the criteria of Korean web accessibility, and then evaluate the web accessibility level of major Internet shopping mall websites in Korea. Based on the evaluation of web accessibility level, we propose and implement an alternative text enhancement method using Excel VBA to increase the rate of alternative text for improving web accessibility. Using the proposed method, even non-specialists of web programming can check and modify the alternative text of the image included in web pages, which can help improve the web accessibility compliance rate.

The conventional educational robots, which are commonly industrial robots or toy robots, use text-based programming to teach the students. Therefore, students have difficulty in studying robotics due to the difficulties of text based language. The developed robot in this study have a camera, which have the color tracking function, and it has various sensors and actuators. It supports the open hardware and uses graphic language based programming. The developed educational robot is programmed by Scratch, which uses graphic modular language. We also present a curriculum, which is based upon the developed robot and Scratch. We applied the robot and curriculum to the primary school students. We obtained satisfactory results comparing it with the conventional robot education. Furthermore, the imagination and execution ability of students showed enhancement in learning robotics. Thus, this fact means the validity and effectiveness of the proposed approach.
