Virtual Fire Control System(VFCS) in attack helicopter is developed. VFCS is comprised of multifunction display, store management computer, mission computer, target acquisition and designation system, mission planning system, weapon simulator and flight simulator. Weapon engagement process under the operational environment of helicopter was considered by using the VFCS. We considered hellfire missile, tow missile, unguided rocket and turret gun. The results of this study will be utilized efficiently on integrated fire control system SIL(System Integration Lab.) in attack helicopter.

In naval gun firing, firing accuracy comes from the combination of each component's accuracy in CFCS (Command and Fire Control System) like tracking sensors and gun. Generally, battery alignment is done to correct the error between gun and tracking sensor by using boresight telescope on harbor and sea. But normally, the battery alignment can compensate only the static alignment error and ignore dynamic alignment error which is caused by own ship movement. There was no research on this dynamic alignment error until now. We propose a new way to analyze dynamic arrangement error by using image of boresight telescope. In case of the dynamic alignment error was due to time delay of own ship attitude information, we propose the way to compensate it.

과학 기술의 발전과 함께 함정에 탑재되는 무기와 각종 장비들은 컴퓨터 시스템에 의해 통제, 조작되는 형태로 변하고 있다. 다수의 장비들에 대한 모니터링 정보를 비롯한 다수의 메시지와 이를 조작하는 다양한 프로세스들을 관리해야 할 필요성이 증가하고 있다. 대규모의 실시간 메시지와 분산 환경의 감시의 일관성을 위해 해외에서는 기술표준화 작업이 진행되고 있으며, 이는 DDS(Data Distribution Service)를 기반으로 구성되고 있다. 본 논문에서는 컴퓨터 시스템에 대한 통제를 위해 OMG의 DDS(Data Distribution Service) 통신 미들웨어와 공개 프로젝트인 Fuse를 이용하여 분산 환경의 모니터링 및 파일 복제 서비스를 제공하는 전투 체계 관리 소프트웨어인 CSIMS를 설계, 구현한다.

본 논문에서는 OBS 망의 에지 라우터에서 소비되는 에너지를 절감하기 위한 통제 기반 동적 버스트 어셈블 알고리즘 (Constraint based Dynamic Burst Assemble algorithm : CDBA) 을 제안한다. 기존의 버스트 어셈블 알고리즘은 망의 성능 및 QoS (Quality of Service) 만을 고려한 고정된 버스트 어셈블 임계값을 사용하였으나 제시한 알고리즘은 에지 라우터에서 발생하는 에너지 소비율을 감소시키면서도 버스트 길이 및 패킷 지연과 같은 지표를 일정 수준이내로 유지함으로써 망의 성능을 보장한다. 제시한 알고리즘 평가를 위해 OPNET Modeler 를 사용하여 시뮬레이션을 수행하였으며, 에너지 절감율 및 패킷 지연 시간 관점에서 기존의 버스트 어셈블 알고리즘과 성능을 비교, 분석하였다.

Since there are differences in the content, structure and functions of interpersonal communication during the practice of school science classes, it needs to articulate the difference of the modality of pedagogical practice in order to understand science teaching in detail. These characteristics of science teaching can be investigated by further insightful analysis on language in the science classroom. In this study, classroom discourse language codes using Bernstein's code theory were analyzed in the case of a middle school science class on the unit of minerals. The discourse language code was identified by the value of classification, which revealed power relations to the contexts of discourse and participants of discourse. It was also identified by the value of framing, which showed hierarchical relation between teacher and students as discourse subjects, and discursive control on the initiative of discourse. The results addressed that six types of discourse language codes were constructed and that those language codes reflected diverse modalities of science teaching from student-centered instruction to teacher-centered instruction in relation to classroom discourse. The modality of science teaching according to the transition tendencies of discourse language code showed dynamic variations of 'controlled student-centeredness inducing teaching' - 'positional student-centeredness permissive teaching' - 'controlled students' participation permissive teaching' - 'controlled student-centeredness facilitative teaching' - 'student-centeredness enhancing teaching'. In addition, results released that discursively and hierarchically weak control of discourse is necessary for enhancing student-centeredness of science teaching. Moreover, teaching practice enhancing student-centeredness can be accomplished by the harmony of a teacher's perception of discourse language code and his/her orientation to constructivist teaching and student-centered teaching.

The purpose of this study is to examine the effect of TSJ-JSM (Job Stress Management) program, which was developed for improving interpersonal relationship and mitigating job stress among social workers through convergence methods with biomedical and social scientific measurements. In order to achieve the purpose, utilizing quasi-experimental design with non-equivalent control group design was applied. Participants were recruited among social welfare residential facility workers with volunteer intention, and 21 participants divided into three groups randomly: experimental, comparison, and control groups consisted of 7 workers respectively. TSL-JSM program consisted of 12 sessions were implemented to experimental group, on the other hands, other employee assistant program with 12 stages was applied to comparison group. Data analysis for verification of TSL-JSM program was conducted with SPSS 25.0. Both social scientific and biomedical scientific measures show that TSL-JSM program has most strong effects on enhancing interpersonal relationship skills and allaying level of job stress by levels of increased HRV SDNN and decreased Corisol.

The future battlefield operation concept does not focus on advanced and complete weapon systems, but requires a new battlefield operation concept that can effectively demonstrate offensive power by combining a large number of low-cost, miniaturized weapons. Recently, research on the autonomous application of major technologies that make up the mission control system is actively underway. However, since the mission control system is still dependent on the operator's operating ability when operating multiple robots, there are limitations to simply applying the automation technology of the existing mission control system. Therefore, we understand how changes in operator capabilities affect multi-robot operation and propose an adaptive mission control architecture design method that supports multi-robot integrated operation by adjusting the level of autonomy of the mission control system according to changes in operator capability.

Rapid globalization process is applying to Science field in Korea. Until now, most researches and government's announcement used to examine the scientific level of Korea by using the number of publications in the SCI Journals. I investigate other aspects of the scientific globalization: a scientific collaboration trend, participations of foreign researchers, and the national level of collaboration networks. There are increasing patterns in collaboration and foreign researchers' participation, and the Impact Factors of the Journals were preceded by inflating trend in the participations of foreign researchers. Also, the breadth and the density are different from each science fields in the national level of collaboration networks. These findings are related to the process of globalization in the Korean science journals and the science fields.

과학과 정보통신 관련 기술 교육은 그 교육적 잠재력이 무한하고 이에 따른 열의 또한 높아지고 있다. 그러나 기초과학 교육의 산실이라 할 수 있는 초등학교 과학 실험 환경은 매우 열악하여 학생들은 각종 위험 상황에 노출되어 있고 교사들은 학생들을 각종 안전사고에서 보호하기 위해 실험 환경을 과도하게 통제하게 되어 학생들은 기본적인 활동에 상당한 제약을 받아 과학에 대한 의욕과 흥미가 저하되는 문제가 발생하게 되었다. 본 연구에서는 이러한 문제점들을 해결하기 위하여 최근 유비쿼터스(Ubiquitous)컴퓨팅 기술로 주목을 받고 있는 RFID(Radio Frequency IDentification) 기술을 이용하여 실험 약품에 고유의 전자태그를 부여하고 Mobile RFID 리더기가 장착된 PDA를 이용하여 약품의 개별 정보와 관련 과학실험 방법을 비롯하여 실시간으로 안전교육을 받을 수 있는 시스템을 통해 안전 조건이 미비한 실험실의 물리적 환경 개선을 통해 보다 능률적이고 심도 있는 과학 실험 환경을 구축할 수 있는 시스템을 설계하였다.

무기체계가 국내개발로 생산되었다 하더라도 이 무기체계의 핵심이 되는 기술 및 부품을 외국에 의존하여 개발하였다면 완전한 우리의 무기라 할 수 없고, 외국이 기술에 대한 통제력을 행사 한다면 그것은 곧 기술종속을 의미한다고 볼 수 있으며 예측할 수 없는 국제안보 환경하에서 기술종속은 곧 안보종속이 될 수 있기 때문에 주요무기체계의 핵심기술 확보는 국가안보를 위해 중요한 것이다. 그러므로 향후 우리 나라의 경우 국제협력연구개발 필요성은 증대될 것으로 전망된다. 그것은 주요 무기체계 개발을 위한 국내의 국방과학기술 수준을 볼 때 핵심기술이 미흡한 분야가 상당하므로 외국과의 협력을 필요로 하기 때문이다.
