Java applet, executed in user's web browsers which is via proxy server on web sever, can approach client files or resources, so it is necessary to secure against malicious java applet. Currently, the previous security countermeasures against malicious java applet use two ways: one is making a filter system to detect malicious java applet hewn in proxy, the other is that establishes another security java virtual machine. However, the first one can not detect unknown malicious java applet, and the other one nay increase loads, because it decides whether there is malicious or not after implementing java applet on proxy server. In this paper, after inserting monitoring function to java applet on proxy server using java-methods substitution and transfer it to user to detect malicious java applet, we propose a technique for detecting malicious java applet that can detect the unknown malicious java applet with reducing loads

Java Card has several applets running on card, and applet can be added easily. Each applet supports different application programs, and includes file system for data management. This paper presents design and implementation of the file system API based on Java Card for the efficient data management in need of the applet. We referred the smart card international standard ISO7816-4 for the file system and used API supported at Java Card. Results show that it is easy to design and operation of file systems during the applet development, also show lighting of applet's source codes and improved access times.

World Wide Web has potential possibility of infrastructure for parallel computing environment connecting massive computing resources, not just platform to provide and share information via browser. The approach of Web-based parallel computing has many advantages of the ease of accessibility, scalability, cost-effectiveness, and utilization of existing networks. Applet has the possibility of decomposing the independent/parallel task, moving over network, and executing in computers connected in Web, but it lacks in the flexibility due to strict security semantic model. Therefore, in this paper, Web-based parallel computing environment using mobile agent, Aglet (Agile applet) was designed and possible implementation technologies and architecture were analyzed. And simple simulation and analysis was done compared with applet-based approach.

본 논문은 자바 에플릿(Java applet)을 이용하여 보존모형과 비보존모형의 온도에 따른 손상확산(damage spreading)의 특성을 분석하였다. 보존모형인 아이징(Ising)모형과 비보존 모형인 격자기체(lattice gas) 및 Driven Diffusive System(DDS)을 다양한 전이확률(transition probability)을 사용하여 온도에 따라 물질내부에서 손상확산이 어떻게 발전하는지를 자바 에플릿 프로그램을 이용하여 시각화하여 손상확산을 명확히 이해하고자 하였다.

As multi-application smart cards have become very attractive mobile devices, card users are able to add and to remove card-applets after card issuance. However, because of constrained memory on a smart card, it is necessary to manage card-resident applets. In this paper, we propose an adaptive applet management algorithm in order to recommend card-resident applets which can be removed. This algorithm's goal is to select card-resident applets in a way minimizes the number of applet downloads. To serve this purpose, our algorithm identifies the applets that are most likely to be executed again, and based on that, decides which should be kept in the memorY and which can be discarded.

많은 중소기업들이 업무를 진행하는데에 있어서 수기로서 작업을 하기도 하고 아니면 간단한 프로그램를 사용하든지 아니면 중소기업형 ERP를 사용하기도 한다. HomePage의 경우에도 있는 경우도 있고 존재하지 않는 경우도 있다. 더구나 WEB으로 업무를 처리하는경우는 상당히 미흡하다. 개발을 하려고 하여도 WEB 기반으로 프로그램을 개발하는데는 Servlet 기반의 방식이 대다수 이다. 이 방식은 중소기업에서 개발하기에는 너무나 많은 개발비용과 유지비용이 들게되고 또한 네트워크 환경의 열악성 때문에 투자대비 효과를 얻기가 힘들다. 본 논문에서 제안하는 시스템은 Applet을 이용하여 중소기업업무 프로그램을 WEB 기반으로 구축하여 자료의 사용을 Internet 또는 Intranet등에서 가능하게 하고 네트워크의 영향역시 AWT기반으로 Applet으로 제작하여 만들어지는 파일의 크기를 작게 구현해서 네트워크의 영향을 최소화 하게 구현을 하고, 프로그램을 클래스화시켜 재사용이 가능하게 하여 개발기간의 단축과 유지보수를 용이하게 하여 비용을 줄이도록 한다.

The purpose of this study is to design and implement a courseware that makes possible interaction between man and computer in the internet. For this, We select the contents of learning and designe a courseware with text, graphic data. HTML, Java script and Java applet. Some advantages of the courseware are as follows. Interactions between man and computer are possible by giving diverse feedback to input-response in the web. And it is possible to access the courseware regardless of time and space when the network environment of user's computer is suitably equipped. Finally, on operator's part, the revision of the courseware becomes easier and on client's part, the system resources are less required.

The World Wide Web provides new opportunities for cyber education over the Internet. The web, when combined with other network tools, can be used to provide useful educational information to learners. Thus, the objective of this paper is to develop Java applet for understanding the concept of Fuzzy Logic Controller (FLC) on the Internet. The developed Java Applet is composed of four frames: fuzzifier, rulebase, inference engine and defuzzifier. Since data transmission can be achieved from one frame to other frames, users can easily observe and understand the process of FLC. The results of this paper can be used to improve the efficiency of lectures in the cyber university.

In this paper, the simplification procedure of Karnaugh Map, which is essential to design digital logic circuits, was implemented as a web-based educational tool by Java applet. The learners can make virtual experiments on the simplification of the digital logic circuit by clicking on some buttons or filling out some text fields. The proposed simplification procedure was implemented as a Java applet which is based on the Modified Quine-McCluskey algorithm. Thus, the implemented Java applet will enable the learners to enhance the learning efficiency as a auxiliary educational tool.

Recently, IoT applications are being deployed in Smart TVs, and these IoT applications are using smart TVs as application platforms rather than broadcast platforms. With the advent of Hybrid broadcast technologies, now it becomes available to develop IoT applications which are coupled to the broadcast information. However, the existing IoT services are not suitable for Hybrid broadcast application since they are built on cloud and require various protocol implementations. In this paper, a Fog Computing-based architecture for hybrid broadcast application is proposed. Instead of accessing IoT services from hybrid broadcast app directly, the proposed architecture places Fog Applet Server between them and distribute loads of hybrid broadcast app to the Fog Applet. The proposed architecture is implemented as a service to control IoT device with hybrid application.
