We know that the all of warfare system has been becoming complex and variety in warfield thru the Gulf-War. The all of warfare electronic systems is designed to inter-operate by networks in recently. Especially Warfare Equipment systems of Men-of-War(War ship) as like KDX(Korea Destroyer, Experimental), FF(Frigate), PCC(Costal Patrol Craft), Submarine are connected by Combat System Databus to the Command system(C2 System), so C2 system can control all of equipments in ship. In this view, the status of network(Combat System Databus) is very critical parameter in war field. So In this paper, we propose the method of Network Management System construction for War ship, and especially propose the architectural design of network management system for DX(Destroyer, Experimental) equipments using SNMP(Simple Network Management Protocol). And Link Utilization is monitored by simulation.

Recently, the Open-Development-Tool-Environment becomes a basic requirement of RTOS (Real Time Operating System) for embedded systems with restricted memory and CPU power in order to develop applications effectively. A remote interactive shell is one of the basic software components which makes users develop, test and control softwares without burdening target systems. In this paper, we have implemented the remote interactive shell with the following functions : loading object modules, spawning and manipulating tasks facilities thru a remote host. Comparing information reference methods with nonredundant overhead, we have achieved the system with easy maintenance. The shell has been developed with Q-PLUS RTOS under ARM EBSA285 target board and NT host.

One of the criteria provided by the law to spatially determine the zones to levy the so-called development impact fee requires that the increase rate of the development permit should exceed that of the entire locality by more than 20 percent. Since the permits are issued to scattered parcels, however, it renders significant difficulties in accurately figuring out the finite local areas that exceed such legal criteria. This study, in this context, tries to join the development permit time-series data with the Korea Land Information System (KLIS) so that, with the aid of the landform layer and existing infrastructure layer, it could pinpoint the local area where the development activities are concentrating. Taking a sector in Yangpyong County as the case, the study demonstrates the methods to designate the zone by processing the permit information data.

RFID middleware is the system software that converts EPC data collected from RFID reader devices into meaningful data, that users want, and transfers the result to the users with a variety of protocols. ALE specification, the RFID middleware specification proposed by EPCglobal that is a leading group of do facto international standards with respect to RFID, can handle only EPC code. Meanwhile, a new code system which is called KKR was proposed by NIDA in order to represent RFID tag data in a specific manner and cultivate the domestic RFID industry. In this case, the existing RFID middleware can not process KKR code system because of inherent attributes of the system. In this paper, we proposed a method of KKR code conversion to properly process KKR code in ALE middieware, implemented our method in real, and adopted it into existing ALE middleware. Also, we proposed a new URN format for RFID tag data to manipulate KKR code in ALE middleware. By using the proposed method, the existing ALE middleware conforming to international specification can handle KKR code effectively, and the integration among RFID middleware and legacy systems can be easily supported also.

This study was done to identify the perception of cancer pain among nurse and 4th grade medical school and to apply it to the development of systematic educational program. The subjects were 258 nurses and 211 4th grade medical school students. The results of the analysis using the SPSS WIN 18.0 statistical program showed statistically significant differences in the next question between the two groups ; "Cancer patients don't get addicted to painkillers the more often they use them.", "Cancer pain can occur regardless of age.", "Injections or neurotheraphy are not temporary, but effective over a long period of time when cancer patients have pain.", "Cancer patients are not easily addicted to painkillers compared to other patients." Therefore, it is necessary to establish the educational direction and related education programs for the theory and practice of systematic cancer pain in both groups.

High Level Architecture(HLA) for modeling and simulation is an international technical standard to achieve simulation interoperability and reusability. Building federation through the interworking of federates is being used in various fields and is being used in KR(Key Resolve), UFG(Ulchi-Freedom Guardian) as a representative in domestic military. Currently, United States Department of Defense emphasizes the HLA compliance test, which confirms the compliance of Federate by using HLA. However, due to the limitations of testing tools, an HLA compliance test of DoD is not able to perform some of the functional tests on HLA/RTI services such as federation storage/recovery services and also exclude inspection of exchange data between federates. To solve these problems, this paper proposes an HLA compliance testing system of ROK suitable for domestic situations. This will enable effective HLA compliance testing and improve interoperability between federates.

As the portion of modern weapons systems equipped with electronic components increases, the presence of embedded software has also increased, subsequently drawing interest in quality management and development methods. Unlike mechanical systems, software is logically intangible, hard to troubleshoot, and hard to reuse, making it hard to utilize limited resources when exposed to failures. The United States had successful results in establishing the Capability Maturity Model (CMM) by studying and applying separate processes for development and quality management of defense software. South Korea has also established, and utilizes, a standard of development and quality management for defense software based on international standards. However, some say those standards still remain at a basic level, and should be modified along with the progress in software. If the standard stays at a basic level, compared to software progression, the cost to reuse and restore resources will increase exponentially. This paper discusses improvement in the test processes for defense software through the Test Maturity Model-integration (TMMi)-derived from the CMM-and presents a blueprint for defense software quality management.

Recently, Chat GPT artificial intelligence (AI) is of keen interest to all governments, companies, and military sectors around the world. In the existing era of literacy AI, it has entered an era in which communication with humans is possible with generative AI that creates words, writings, and pictures. Due to the complexity of the current laws and ordinances issued during the recent national crisis in Korea and the ambiguity of the timing of application of laws and ordinances, the golden time of situational measures was often missed. For these reasons, it was not able to respond properly to every major disaster and military conflict with North Korea. Therefore, the purpose of this study was to revise the National Crisis Management Basic Act, which can act as a national tower in the event of a national crisis, and to promote artificial intelligence governance by linking artificial intelligence technology with the civil, government, military, and police.

In order to monitor the growth environment of new varieties of crops, it is necessary to build the agricultural production infrastructure and strengthen the agricultural resource management system using popular smart sensor tag technology. In addition, the infrastructure for improving high-quality new varieties of crops using IoT technology and the monitoring system must be strengthened. In other words, widespread smart sensor (RFID UHF Sensor Tag) technology for environmental monitoring required for improving new crop varieties is desperately needed in the smart farm environment. Therefore, in this paper, we implemented an integrated sensor that can implement smart tag functions based on heterogeneous integrated sensors. In addition, we developed a technology that can manage crops in real time through the implemented smart integrated tag and smartphone linkage. For this purpose, an integrated antenna capable of RFID and Bluetooth communication was constructed. In addition, a communication method that allows information to be collected directly from the smartphone through the Bluetooth function was used.
