사회공학적 공격이란 인간의 심리를 이용하여 보안 위협 상황을 갖게 하는 공격을 말한다. 그렇기 때문에 사회공학적 공격을 막기 위한 보안 솔루션은 그 한계가 있기 마련이다. 그리하여 본 논문에서는 사회공학적 공격에 대비하는 보안훈련시스템을 제안한다. 스팸 및 피싱 이메일을 수집하여, 시그니처 기반 필터링을 이용하여, 최신의 사회공학적 공격 이메일을 분석한 후, 가상으로 사회공학적 이메일 공격을 실시하여 훈련대상자들이 최신의 사회공학적 공격에 대비하는 능력을 갖추게 하는 보안 훈련 시스템을 설계하였다.

The purpose of this study was to empirically examine what effects of education and training program factors such as content, method, environment and instructor on learning satisfaction, job satisfaction and organizational performance. The education and training program factors like content, method and instructor were found to significantly affect learning satisfaction and job satisfaction. But environment for that program had no significant effect on any of both the satisfaction.

본 연구에서는 MHEG을 기반으로 한 원격 교육/훈련 시스템으 설계한다. 설계하는 시스템은 코스웨어를 제공하고, 비동기모드로 브라우징하여 개별 학습을 지원하던 기존 시스템과는 달리 , 교육적 효과를 높이기 위해 비동기 방식과 동기 방식을 동시에 수용할수 있도록 설계하였다. 특히 동기 방식은 사용자 공동 작업 환경을 위한 세션 관리 모듈을 두어 실시간 화상 강의 응용에서 학습자 및 세션 제어에 대한 연산을 제공함으로써 학습 효율을 향상시킬수 있으며, MHEG 표준을 도입하여 학습자와의 실시간 상호 작용을 충분히 지원함으로써 훈련 시스템에서의 시뮬레이션 지원 능력을 극대화 할수 있도록 하였다.

A flight simulator is a device that allows pilots attain proficiency of various situations and a sense of flight, and as interest in scientific training increases in modern aviation, aviation training organization develop and operate simulators. Therefore, in this study, the process of developing a motion-based helicopter simulation Training Device using a commercial program. Citing previous studies, the specificity of helicopter flight education and the positive effect of motion simulators were confirmed. In addition, the design and program of the motion device were studied in the process of checking the configuration and current regulations of flight simulation training devices and developing a helicopter motion simulator. A motion program was set based on the system design and structural design of the flight simulator, and data received from the flight simulator was identified to confirm the expected operating shape. Through this study, we intend to create a positive expected effect on pilot training by completing a motion-based helicopter simulator.

In order to provide realistic traffic to the cyber warfare training system, it is necessary to prepare a traffic distribution plan in advance and to create a training data set using normal/threat data sets. This paper presents the design and implementation results of a method for creating a traffic distribution plan and a training data set to provide background traffic like a real environment to a cyber warfare training system. We propose a method of a traffic distribution plan by using the network topology of the training environment to distribute traffic and the traffic attribute information collected in real and simulated environments. We propose a method of generating a training data set according to a traffic distribution plan using a unit traffic and a mixed traffic method using the ratio of the protocol. Using the implemented tool, a traffic distribution plan was created, and the training data set creation result according to the distribution plan was confirmed.

This paper proposes a state machine design methodology in which an interactive robot that mimics discrete trial training (DTT protocol) can support social interaction training for children with autism. The robot applied to social interaction training uses the response to the provided training stimulus as a quantitative indicator by processing the data received from the sensors measuring the behavioral response of the child. In this process, the state machine is used as information that classifies the state of the acquired data and provides the subsequent stimulus for DTT protocol. Through the joint attentional training, it can be used as evidence-based treatment information by quantitatively classifying the data on the number of sustainable and DTT protocol and the child's response, as well as the current reaction status of the child to the observer performing remote monitoring. At the same time, it was confirmed that it is possible to properly respond to misrecognition situations.

Recently, the drone industry is rapidly expanding as it is suggested that it will be used in various fields. As the size of the drone market grows, interest in drone-related certificates is also increasing. However, the current drone-related qualification system and education system are insufficient. Thus this study, analyzed the necessity of drone training, the features of functional games, and the effectiveness of educational training using AR through related technical studies to solve the practical difficulties of drone educational training. Later, drone educational training game contents using AR were divided into practice mode and test mode based on the drone national qualification course practical test, and the result screen was displayed at the end of the curriculum so that players could learn by level and evaluate the results on their own. In addition, constructed a hybrid processing system and network and AR operation system for response rate and response speed, implemented drone training game contents utilizing AR based on the design contents. It is expected that the use of game content using AR presented in this paper for drone training will further alleviate environmental difficulties and improve the sense of immersion in play, which will lead to a more effective drone educational training experience.

Criticality prediction models that determine whether a design entity is fault-prone or non fault-prone are used for identifying trouble spots of software system in analysis or design phases. Many criticality prediction models for identifying fault-prone modules using complexity metrics have been suggested. But most of them need training data set. Unfortunately very few organizations have their own training data. To solve this problem, this paper builds a new prediction model, KSM, based on Kohonen SOM neural networks. KSM is implemented and compared with a well-known prediction model, BackPropagation neural network Model (BPM), considering internal characteristics, utilization cost and accuracy of prediction. As a result, this paper shows that KSM has comparative performance with BPM.

연안선은 중 대형선에 비하여 사고의 위험이 높고 작업 환경이나 안전에 대한 시스템적인 완성도가 매우 취약하다. 또한 바쁜 운항 스케줄과 승무원의 자질등의 여건으로 인하여 비상대응훈련이 잘 시행이 되지 않는 것이 현실이다. 여기에 현재 시행중인 훈련에 대한 시나리오도 중 대형선의 시나리오를 가지고 수정해서 사용하는 경우가 많고 본선에 적합하지 않는 훈련 시나리오를 가지고 훈련을 하는 경우도 많다. 본 연구는 이러한 문제점을 개선하고 연안선의 현실에 맞는 시나리오를 개발 및 자발적 참여유도를 통하여 연안선에서 시행되는 훈련의 효과를 증대시키고 나아가 안전한 해양문화에 이바지하는데 그 의의가 있다.
