기존의 전산 장비 관리 시스템은 전산실에서 문서로만 관리되던 장비 정보들을 전산화하여 관리할 수 있도록 만들어졌다. 하지만 문서로 정리된 장비들을 전산화하는 것에만 중점을 두다 보니 등록할 수 있는 장비에 한계가 발생하고 필요한 장비를 찾는데 어려움을 겪고 있다. 또한, 등록된 장비가 현재 사용하고 있는 장비인지 확인하는데 불편함을 초래하였다. 본 논문에서는 이와 같은 문제를 해결하기 위해 전산 장비 관리 시스템을 재설계하고 구현한다. 이를 위해 기존 전산 장비 관리 시스템을 전반에 걸쳐 면밀히 분석하였으며 시스템을 사용하는 공무원과 관리업체들의 의견을 반영하여 시스템을 개선할 수 있도록 설계 및 구현하였다. 성능평가에서는 기존 시스템의 장비 등록 수와 장비 검색 정확도를 비교하여 개선된 시스템의 효율성을 입증하였다.

The existing computer equipment management system is designed to computerize and manage equipment information that was managed only by documents in the computer room. However, the existing system focuses on computerizing the equipment arranged in the document, so there is a limit to the equipment that can be registered and it is difficult to find the necessary equipment. In addition, it caused inconvenience to confirm whether the registered equipment is currently used. In this paper, we redesign and implement the computer equipment management system to solve the problem. For this purpose, the existing computer equipment management system was thoroughly analyzed throughout, and the system is designed and implemented to improve the system by reflecting the opinions of public officials and management companies using the system. In the performance evaluation, the efficiency of the improved system is proved by comparing the number of equipment registrations and equipment search accuracy of the existing system.

DESIGNIN AND OPERATION OF DIGITAL EVIDENCE MANAGEMENT SYSTEM APPLYING COMPUTER FORENSICS AND ELECTRONIC CERTIFICATION Digital evidence will be used as a term, which means the electronic form of information which is necessary to confirm or prove the factum of all kinds of behaviors committed through the devices which have data processing ability including computer. It is expected that there will be the increase of legal conflicts surrounding electronic commerce activities as well as the increase of cyber crimes, as the number of Internet users are getting bigger. In order to solve the problems of conflicts derived from electronic commerce, the factum of electronic commerce activities must be confirmed. In order to confirm the factum of electronic commerce activities, the evidence is prerequisite. Almost all evidences relating to the electronic commerce activities exist in digital form. For the reason that the digital evidence can be easily damaged and changed, special management is required to collect, analyze, and preserve the digital evidence. In order to meet this requirement, this study proposes a basic model of digital evidence management system applying computer forensics and electronic authentication.

Inappropriate work postures in industry can cause musculoskeletal fatigue and strain, leading to work inefficiency, quality problems, and safety accidents. Therefore, a system capable of recognizing and intervening in dangerous postures during work in real time is needed not only for industrial safety but also for project performance management. This study proposes a 2-channel real-time work posture management system that combines RULA analysis based on frontal upper body images and REBA analysis based on lateral full-body images. The proposed prototype was implemented using synchronized frontal and lateral cameras and was preliminarily applied to three participants performing terminal connection tasks in an actual manufacturing environment under no-alarm and alarm conditions. The system records posture risks every second and generates an alarm sound if a dangerous posture persists in the same body part for more than 3 seconds. As a result of the preliminary application, the rate of adopting dangerous neck postures under alarm conditions decreased. The maximum time maintained in dangerous neck postures was also reduced. However, since this study was conducted with only three participants and a single task condition, these results should be interpreted as preliminary results demonstrating the applicability of the prototype rather than as general effects.

근래에 와서 치료방사선학 영역에서의 전산화가 급속히 이루어지고 있으나 그 전산화의 대부분은 치료계획용 계산에 치우쳐져 있고 환자정보관리, 퇴원환자의 추적검사, 환자관리사무에 있어서의 전산화에 필요한 프로그램 등 환자관리에 필요한 프로그램은 매우 적으며, 상업적으로 개발된 프로그램은 일반화하기에는 많은 문제점을 갖고 있다. 이에 저자들은 16비트 개인용 컴퓨터를 이용하여 환자 현황 관리 프로그램을 시험 제작하였다. 1. 환자정보의 입력은 특별한 부호나 숫자를 사용하지 많고 현재 우리가 사용하는 영어나 한글을 그대로 쓸 수 있었다. 2 환자정보의 분석은 간단한 명령이나 키 동작으로 이루어질 수 있으며 특히 환자 현황에 대한 도표를 즉시 묘출할 수 있었다. 3. 환자관리정보의 내용은 기존 프린터를 이용하여 쉽게 문서화할 수 있으며, 학술발표, 강의재료 및 교육자료로 사용할 수 있었다.

Currently, many computer systems are used in many areas of medicine including radiation oncology. For the most part, the computer system has proved to be useful in radiotherapeutic planning and dose calculation. There has been attempts to develop computer system including information management of patients, patient tracing, and office automation in radiation oncology department. But some of these available commercial systems have shortcomings. We developed a management system of patients in our radiation oncology department that integrated most of items for the evaluation of patents. In particular, the data were stored in a natural language (noncoded) and made themselves easily understandable by all clinical groups. In addition , the data could be isolated in files from which the computer could generate graphs and static data by the use of some simple commands. The system provided us with not only the functions of case review but functions of preparation of conferences, lectures and resident teaching.

컴퓨터 실습실에서 이루어지는 실습수업은 교실수업보다 학생들에게 체계적으로 교과 내용을 전달하기 어렵다. 그 이유 중 하나는 실습수업 중 학생들이 실습과 무관한 프로그램 사용 등으로 인해 수업의 집중력이 저하되기 때문이다. 이를 해결하기 위하여 학생 컴퓨터를 통제 제어하는 많은 시스템이 있으나 일선 학교의 교사들은 사용상의 불편성과 기능 부족으로 인하여 실습수업관리에 있어 도움을 주지 못하고 있다. 본 연구에서는 기존 실습실 관리시스템의 사용 중 발생하는 문제점을 분석하여 학교 현장의 컴퓨터 실습수업에서 학생들의 적극적인 수업 참여 유도와 교사의 효율적인 수업관리 기능을 제공하기 위한 컴퓨터 실습수업 관리 시스템을 설계하고 구현하였다. 또한 구현한 시스템을 실제 학교 현장에 적용하여 효과성을 검증하였다. 검증결과는 제안 시스템이 수업 집중력을 향상시켜 학습자들이 학업성취도가 향상되었다는 것을 보여주었다.

Generally, teaching in computer Labs is more difficult than teaching in a normal class for teachers to give students systematic learning. One of the reasons is that the students who participate in the class tend to use the programs that are not related to the practice included in the curriculum. Therefore, the students cannot focus on the subjects that they should do. To solve this problem, there are many kinds of systems that can control the students' computers. However, they cannot help teachers to manage the students and computers due to the inconvenience of usage and the lack of functions. In this study, we analyzed the problems in the computer-practice classwork and designed a new system to support that the students can participate in the computer classes with more attention. In addition, it is offered that the computer teachers can manage the classes and the students more efficiently with this new system. For these purposes, the effects mentioned were approved before in the real lab situations. Experimental results showed that the proposed system can improve the rate of the students attention, leading them to get better grades on the achievement test.

In nuclear power plants, nondestructive examinations(NDE) plays an important role in ensuring the integrity and reliability operation. As the number of plants and operational time increased, manual handling of voluminous data associated with PSI/ISI(preservice/inservice inspection) could result in many errors or mistakes in writing the examination plan or other reports. Several new approaches to process the data have been attempted and DBMS(Data Base Management System) has been well known concept with a faster and more accurate data processing. This paper proposes an application program, called NDTSYS designed with DBMS in micro computer. The program could be used for a tool to add new records to a data base, change existing records, delete records and request reports with the data base. It would be helpful to the user who manage the PSI/ISI data with minimal time and effort.
