Generally, a software development process is composed with requirements analysis, design, coding, test and maintenance. However, some changes of the design step are difficult to complicate the next step in the development process. It always causes the disagreement between design and implementation step. In this paper, we have developed a tool which can generate an application program. The tool can reduce the disagreement between system design and implementation and recognize the business logic to develop the software rapidly and flexibly In addition, we proposed a non-program-based application program system approach was proposed, In. We can generate and modify an application program with this method which can edit the meta data of a system design by the dynamic method for the execution time.

In this paper, we implement a navigation software of a Global Navigation Satellite System (GNSS) receiver based on a commercial purpose GNSS software receiver platform and verify its performance by performing experimental tests for various GNSS signals available in Korea region. The SX3, employed in this paper, is composed of an application program and a Radio Frequency (RF) frontend, and can capture and process multi-constellation and multi-frequency GNSS signals. All the signal processing procedure of SX3 is accessible by the receiver software designer. In particular for an easy research and development, the Application Programing Interface (API) of the SX3 has a flexible architecture to upgrade or change the existing software program, equipped with a real-time monitoring function to monitor all the API executions. Users can easily apply and experiment with the developed algorithms using a form of Dynamic Link Library (DLL) files. Thus, by utilizing this flexible architecture, the cost and effort to develop a GNSS receiver can be greatly reduced.

The COMS flight software is implemented by ADA language and the high level application program language (APL). The APL is used to implement the Interpreted Program (IP) functions which are running on the processor. The IP functions have been developed for the payload management and monitoring with the automatic on-board operational procedure. The IP allows an easier re-programming if necessary. The ground can load or unload IP separately from ADA code in the RAM flight software. The uploaded IP is interpreted and executed by the Interpreted Program Environment (IPE) which is one of the functions implemented in the RAM flight software. In this paper, we introduce the IP and IPE function.

This Paper makes an attempt to suggest a process of automatically generating application software based on the Entity-Relationship model 1. The designer develops an E-R model of an real-world system. 2. The designer inputs the entity and relationship types, and attributes shown in the E-R model, and also the basic operations of the application system to the software generator. 3. The application generator produces database schema and link information between application programs, and then automatically generates a stereo-type application system. In order for the automated application generator to build the application system in a systematic way, four basic program generation rules have been suggested. A set of computer programs have been developed in order to show the applicability of the automated software generation process suggested in this paper. By following each rule with the generator, the designer can build an application in an efficient manner compared with traditional (manual programming) approaches. It has been demonstrated from the case study that the idea of applying an automated generator in systems development based upon the E-R model is feasible.

The technology suggested in this study is the method to contain executable software in a portable storage devices like the USB and install an application program to operate it in any client devices. To solve this problem, we can store pre-scanned information on the above client's files, registry, and services in the device before installing the proper application program to be installed using the scanning method and manage in the USB the resources that generated and changed by post-scanning the information after installing the above application program in the client's device. After that, necessary files in the client to be used can be copied for using, and after use, related files are deleted, and it also includes the process to return to the previous system environment. This method is advantageous in that once any sort of application programs needed to be installed gets to be installed in an external portable storage devices like the USB, the application program installed can be operated in any computer not raising any issues like illegal copy.

Software-Defined Networking (SDN) offers several advantages in dynamic routing, flexible programmable control and custom application-driven network management. However, the programmability of the data plane in traditional SDN is limited. A network operator cannot change the ability of the data plane and perform complex packet processing on the data plane, which limits the flexibility and extendibility of SDN. In the paper, AP-SDN (Action Program enabled Software-Defined Networking) architecture is proposed, which extends the action set of SDN data plane. In the proposed architecture, a modified Open vSwitch is utilized in the data plane allowing the execution of action programs at runtime, thus enabling complex packet processing. An example action program is also implemented which transparently encrypts traffic for terminals. At last, a prototype system of AP-SDN is developed and experiments show its effectiveness and performance.

Recently, the computer software technology is not keeping pace with the increasing demand of application software development and rapid changes in business environment. To overcome this "software crisis", many researchers have studied the methodologies to improve the productivity in software development and the flexibility of software usage. Among these methodologies, the most promising and intensively studied methodology is the Object-Oriented Approach The purpose of this study is, therefore, to examine the applicability of the Object-Oriented Approach for improving productivity and flexibility in Management Information Systems development. For an application, we selected a financial planning model, especially focusing on the budgeted income statement. In this thesis, we identified relevent objects in the budgeted income statement, and represented them in the object models. By implementing these object models using C++ language, we evaluated their adaptability in the budget-making process, and showed, by comparing them with the existing Planning '||'&'||' Modeling Languages such as IFPS(Interactive Financial Planning Saystem), their practicability in Management Information Systems. The results of this study are as follows: First, the same object models can be used in making the budgeted income statement both in the department level and in the corporate level. Second, the object models provide the flexibility and extensibility of an application program in case of the changes in business environment. Third, the Object-Oriented Approach is a practical methodology to improve the productivity and cut down the maintenance cost of application software development.t.
