In this paper we propose the network traffic monitoring system that can supported network and system operation, management, expansion, and design using network analysis and diagnosis to a network administrator. The proposed system consists of two parts: analysis server for collection and analysis of the network information. and supports real-time monitoring of network traffic, and client system shows user a graphical data that analyzed a returned result from the server This system implements web-based technology using java and contributes to enhance the effectiveness of network administrator's management.

자바 언어의 중요한 특징 중의 하나는 어떤 기계에서든지 실행될 수 있다는 점이다. 이러한 플랫폼에 대한 독립성은 자바 프로그램이 바이트 코드 형태로 배포되기 때문에 가능한 일이다. 바이트 코드는 특정 기계에 종속되지 않고 자바 가상 머신(Java Virtual Machine:JVM)를 지원하는 곳이면 어디에서든지 실행 가능하다. 그런데 바이트 코드로 번역된 코드에는 자바 소스 코드의 정보가 그대로 포함되어 있는데, 이로 인해서 바이트 코드에서 자바 소스코드로의 역컴파일(Decompilation)이 쉽게 이루어진다는 취약점이 있다. 본 논문에서는 자바 바이트 코드의 난독화 기법을 살펴보고, Code Encryption Algorithm을 이용해서 역컴파일 하기 어려운 형태로 만드는 기술인 코드 난독처리(Code Obfuscation) 기법을 제안하였다.

현재의 이동통신 단말기를 이용한 무선 인터넷 서비스는 단순히 텍스트 기반의 서비스로서 동적인 이미지나 그래픽을 보여주지 못하고 있다. 본 논문에서는 이동통신 단말기를 통해 무선 인터넷 컨텐츠의 다운로드와 삭제가 가능하게 하고 동적 그래픽과 도표 등을 보여줄 수 있는 J2ME(Java 2 Micro Edition) 기술을 분석하였다.

Recently, Web map service is actively accomplished in both private companies and public offices. As a platform, it exists variously from desktop to smartphone. The technology being used has a trend to develop continuously. Also, Web map system provides various open API for people who use geospatial service and data mashup. In this paper, RIA technology which is popularly used recently in web map service w ill be applied to introduce the functions different language map services are mostly using. Based on users' feeling about different web browser's speed, test and analysis have been accomplished. The result is that there are different characteristics according to different functions such as JavaScript, Silverlight, Flex. Actual test has been personally carried out on map service in Seoul GIS portal system. The comprehensive conclusion is that Silverlight has more outstanding function compared with other RIA techniques under the test environment.

The implementation of physical or social distancing during the Covid-19 pandemic has an implication on the shifting of conventional to online business activities. This study aims to explore how financial support, perceived benefits, external pressure determine social media marketing as well as understanding the role of internet and e-business technology (IEBT) that occurs in this relationship. This study adopted a quantitative study with Structural Equation Modeling (SEM)-based variance Partial Least Square (PLS), which aims to enhance understanding of the relationship between variables. The surveyed population of this study came from 123 small- and medium-sized enterprise (SME) owners in East Java of Indonesia, using an online survey and selected with the convenience random sampling method. The findings of this study indicated that the perceived benefits and external pressure have a positive effect on the adoption of IEBT. However, financial support failed in explaining SMEs' adoption of IEBT. This study confirmed that the adoption of IEBT has successfully mediated the influence of financial support, perceived benefits, and external pressure on social media marketing. Despite the samples solely collected from East Java, this study is the first step in research related to the social media marketing in SMEs in Indonesia.

In this paper, an example of implementation of a embedded system technology for web based monitoring and control system is presented. For it interfaces with target board as an embedded system was developed, which was applied to specific green room model and verified of its usefulness. We implemented client/server socket programs using Java classes, and web based green room monitoring and control system as an user interface using JavaApplet. The implemented system did send information of green room model to client programs well on TCP/IP and control signals from client to green room model well too.

Electronic commerce offers the opportunity to integrate and optimize the global production and distribution supply chain. Rapid response to changes in demand and customer preference, and the ability to exploit new technologies, are becoming critical. The computer of the various corporations communicate with each other to determine the price and the availability of the components, to place and confirm orders, and to negotiate delivery time scales. In this paper, We describe a trading system that is based on mobile agent technology, called aglet. Aglets for the buyer and sellers are dispatched to the various marketplace, where they negotiate autonomously orders and deliveries, returning to the buyer and seller with their best deals for approval. We show that the electronic commerce system is feasibly built by using the Java aglet technology to demonstrate for simulating a traditional retail marketplace.

This research investigates the role of entrepreneurial leadership in micro-enterprise development in the district of Majalengka in West Java, Indonesia. This study applied a qualitative content analysis method to understand the phenomenon of micro-enterprises comprehensively. The data of this research was collected using surveys, interviews, and a group discussion. The findings indicated that technological information adaptation plays a crucial role in the development of micro-enterprise development. Since the group of millennials dominated the leadership, it has provided more creativity by implementing technological information instead of the previous generation that faced difficulties in adopting the technology. This study noted that inadequate technology adaptation makes micro-business gradually lose customers, and the business was threatened to close. Meanwhile, the role of leadership drives the business development, sales have risen, the number of products has been increasingly diverse, and business capital and number of employees have grown. The establishment of an entrepreneur group could facilitate peer-to-peer contact, knowledge transfer, training, and intervention to enhance leadership and business development. This finding pointed out that the leadership will successfully influence business development when supported by several characteristics such as manage the business, capture opportunities, confidence, firmness, personal integrity, communication, and social and technical expertise.

RSA is the most widely used public key algorithms. Payment via the SSL communications, and user authentication using RSA secure shopping mall that can protect the user's valuable information in the process of building. SSL-based electronic signature technology and encryption protocols for this technology are electronic documents are delivered to the other party through a separate encryption process, the information sender to enter information on a web browser (user) and the recipient (the Web server of the site Manager), except you will not be able to decrypt the contents. Therefore, the information is encrypted during the transfer of electronic documents even if hackers trying to Sniffing because its contents can never understand. Of internet shopping mall in the user authentication 'and' Communications' SSL secure shopping mall built with the goal of the methodology are presented.
