As a recent dominant web trend, mobile first strategy has been emphasized, and interests with respect to responsive web that provides effective methodology to various mobile devices and their display resolution are also increasing. However, it is an early adoption stage in web mapping for geo-spatial applications. This study is to present some practical examples of layouts using responsive web technologies linked to geo-spatial open platform. Suggestive consideration points for further application of responsive web to geo-spatial services are presented. On test implementing, HTML5, JavaScript, and CSS3 were used, and web mapping processing using OpenLayers was performed. It is expected that responsive web applications for contents derived from geo-spatial information or location data increase.

정부는 국내산 풀사료의 경쟁력을 강화하기 위해 풀사료용 기계장비 및 제조비 등의 지원에 해마다 1,000억 이상의 예산을 사용하고 있다. 이에 수반한 보조금의 공정한 집행을 위한 절차와 서류는 매우 복잡하기 때문에 집행 및 정산에 상당한 행정비용이 발생하여 국내 생산 확대의 걸림돌로 적용하고 있는 실정이다. 또한 풀사료는 생산시점의 환경(습도, 온도 등), 수분함유량, 압축압력, 풀사료 품종 등에 따라 품질이 달라지는데 품질기준이 미흡해 유통활성화에 걸림돌이 되고 있다. 풀사료 생산이력 정보 수집에 필요한 센서, IoT 통신기술 등은 상용화 수준에 도달했으나 풀사료 생산현장에 적용하기 위해서는 풀사료 수확기 등과의 통합이 필요하고, 데이터에 기반한 과학적 정책 입안을 위한 기반 데이터 축적이 필요하다. 이를 위해 본 연구에서는 국내산 풀사료의 생산량 증대 및 유통 활성화를 위한 IoT 기반의 풀사료 생산이력관리 시스템을 개발 중으로, 우선 관리 기준이 되는 표준 데이터를 정립해 DB화(化) 하고, 풀사료 수확현장에서 필요한 데이터를 확보하기 위한 생산이력 생성장치 및 생산이력 수집장치와 이를 IoT망을 활용해 전송하기 위한 생산이력 송신장치를 개발하며 수집된 데이터를 통합 데이터베이스화(化) 하여 다양한 사용자에게 유무선 인터넷을 활용해 정보를 제공하는 웹/앱을 개발 중이다. 개발을 위한 핵심 기술로는 풀사료 수확기에 부착된 다양한 센서에서 생성되는 압력 등의 데이터를 실시간으로 취득하는 기술, 제어용 컨트롤러 설계 기술, 센서 데이터 가공 기술, IoT망을 이용한 실시간 전송 기술, 풀사료 통합 DB 구축 기술, Full Stack JavaScript 기술 등이 있다. 본 시스템를 풀사료 현장에 적용하면 풀사료 현장 조사 시간 및 비용 절감, 풀사료 생산/유통/보조 업무 전반의 효율화 및 투명화, 생산이력제 정착으로 풀사료 온라인 유통 활성화 및 물류비 절감, 센서, 측정장치, 표기장치 판매 및 유지보수 등 농업분야 신규사업 창출이 가능하다.

NMS (Network Management System) is a system that is used for a small or large networks management. As the size of network becomes larger and the configuration information become complicated, it becomes more difficult to grasp the network status and it takes much time to diagnose the failure of the network equipment. In this paper, to alleviate the problems of NMS we implement web-based network topology automatically using JavaScript, Python, HTML5 based TWaver. The detailed implementation of the system include the automatic collection of the connection information based on the equipment information registered in the NMS system, the implementation of the web-based network topology and the remote fault diagnosis. In the network topology, we can expect to improve the quality of the NMS system through structured data management by adding the configuration management, fault management and performance management functions in a comprehensive manner.

In this study, the wrapper database description language and model is suggested to collect product reviews from Korean shopping malls with multi-layer structures and are built in a variety of web languages. Above all, the wrapper based web crawlers have the website structure information to bring the exact desired data. The previously suggested wrapper based web crawler can collect HTML documents and the hierarchical structure of the target documents were only 2-3 layers. However, the Korean shopping malls in the study consist of not only HTML documents but also of various web language (JavaScript, Flash, and AJAX), and have a 5-layer hierarchical structure. A web crawler should have information about the review pages in order to visit the pages without visiting any non-review pages. The proposed wrapper contains the location information of review pages. We also propose a language grammar used in describing the location information.

With the growth of Web services and the development of web exploit toolkits, web-based malware has increased dramatically. Using Javascript Obfuscation, recent web-based malware hide a malicious URL and the exploit code. Thus, pattern matching for network intrusion detection systems has difficulty of detecting malware. Though various methods have proposed to detect Javascript malware on a users' web browser, the overall detection is needed to counter advanced attacks such as APTs(Advanced Persistent Treats), aimed at penetration into a certain an organization's intranet. To overcome the limitation of previous pattern matching for network intrusion detection systems, a novel deobfuscating method to handle obfuscated Javascript is needed. In this paper, we propose a framework for effective hidden malware detection through an automated deobfuscation regardless of advanced obfuscation techniques with overriding JavaScript functions and a separate JavaScript interpreter through to improve jsunpack-n.

This paper presents the design process of an agricultural data sharing platform intended to address major challenges faced by the domestic agricultural industry. The platform was designed with a user interface that prioritizes user requirements for ease of use and offers various analysis techniques to provide growth prediction for field environment, growth, management, and control data. Additionally, the platform supports File to DB and DB to DB linkage methods to ensure seamless linkage between the platform and farmhouses. The UI design process utilized HTML/CSS-based languages, JavaScript, and React to provide a comprehensive user experience from platform login to data upload, analysis, and detailed inquiry visualization. The study is expected to contribute to the development of Korean smart farm models and provide reliable data sets to agricultural industry sites and researchers.

In this paper, we study the synchronization method of animated simulations and VRs for on-line virtual reality education system. To build the data of animated simulations and synchronization modules of VRML content, the media-synchronizing technology, HTML + TIME and scripts are used. The VRML control module ismade into Java applet using the Java EAI provided for the web and the interface for VRML contents. To control the animation of VRML contents, the node information is extracted, and an animation production template capable of controlling animation in inter-connection with VRML content is made. With evaluation of the animation control performance, processing speed, synchronization performance between media in the system built, more improved results are obtained. We would like to suggest a education system with easy system construction and various multi-medium applicability by realizing HTML + TIME media synchronization and VRML web 3D virtual reality creation techniques, and animated images and 3D animation controls according to time using Java through this study.

Recently, variety Web applications which is used Web2.0 are being developed and serviced. In this paper, we implemented Schedule Management Program for the individual and group based on Ajax applications, which apply the MVC design pattern with Java Servlet in order to complement Schedule Management Program which is developed with server-script languages. Also, we improved utilization of applications to provide various additional service through mash-ups built by combing APIs.

The purpose of this study is to develop an XML based GUI that can search for satellite image information which is converted to XML data format and stored in the database server on the web, and modify and reuse data. In order to implement these functions efficiently, we used a DOM interface of XML that increases the efficiency of accessing the document structure. We used HTML and Java script programming to facilitate this interface. The system was applied to the management system of satellite images in the Research Institute of SFC at Keio University. Our results confirmed the technical functionalities.

One of the most important factor while developing web application is to separate presentation and business logic lowering the maintenance cost. There are various web application development tools mainly categorized as script based such as Servlet, JSP, ASP.NET techniques and dynamic server page development frameworks such as Struts, JSF (Java Server Faces), Spring MVC etc. These tools provide web tier processing solution but not the complete separation of presentation and business logic. In this paper, we developed custom tog component that separate presentation and business logic, to process them we also developed container. In addition, DOM tree is applied to the developed container to manage the presentation effectively.
