Delayed repair to the failure of weapon system can cause enormous damages to military operation. Various materials like diagnostic equipment, general and special tools, technical manuals(maintenance manual and illustrated parts breakdown) and drawing documents are required for maintenance. For existing weapon systems the distributed environment of these various materials reduces the maintenance effectiveness of maintenance crew. In this paper, to provide the information of maintenance procedures and supply to the maintenance crew we develope a digital interactive electronic technical manual of the technical documents which can be used easily in computer through question and answer method and improve maintenance effectiveness and minimized repairing time.

With the recent global trends in environmental preservation, the importance of sustainable construction is being highlighted in Korea. In particular, the trend is being discussed about life cycle of the apartment houses in various aspects. However the Korean construction market and housing policy have been increasingly focusing on supplier. Structures become progressively obsolete after a certain period, but their durability can be extended with proper maintenance management. Accordingly, if maintenance management on the structures is made efficiently, waste of construction energy and damage to the environment and economic loss due to early demolition and reconstruction can be effectively prevented. Therefore, this study aims to suggest the user manual design for the efficient maintenance in apartment housing

군용 항공기에 대한 모든 정비작업은 항공기 정비매뉴얼의 내용을 기반으로 수행되고 있다. 많은 정비 작업 가운데 특히 부품의 교환작업은 정비작업 가운데에서도 그 비중이 가장 높다. 부품의 교환작업에서는 부품의 형상 파악과 부품간의 체결관계 및 작업절차에 대한 정확한 이해가 대단히 중요하다. 그러나 군은 물론 민간에서 사용되는 정비매뉴얼은 모두 정비작업절차를 간단한 설명과 개략적인 그림으로 표현하고 있어 정확한 작업절차는 물론 부품의 형상을 이해하는데도 어려움이 있다. 반면에 항공기 부품을 3D 모델로 제작한다면 부품을 자유로운 방향에서 관찰할 수 있을 뿐만 아니라 3D 모델링 SW에서만 가능한 강력한 가시화(visualization) 기능을 통해 내부형상이나 체결관계도 쉽게 확인이 가능하다. 특히 정비작업을 3D 애니메이션으로 제작하면 실제와 동일한 순서로 정비작업을 3D 영상으로 관찰할 수 있어 작업절차를 직관적으로 파악하는데 도움이 될 것이다. 이에 본 연구에서는 3D 모델링 SW인 Solidworks를 활용한 3D 정비매뉴얼 개발방법을 제안하고 이에 따라 B747 항공기의 통합구동발전기 교환작업에 대한 3D 정비매뉴얼을 개발하였다. 또 개발된 3D 정비매뉴얼을 기존매뉴얼과 비교하여 그 장단점을 파악하였다. 정비매뉴얼에서 부품 교환에 대한 내용은 기종에 관계없이 비슷하므로 본 연구에서 제안된 방법은 군용항공기용 정비매뉴얼 개발에도 충분히 적용이 가능할 것으로 기대된다.

To collection of field data for development of maintenance manual of Han-ok, we investigated defects which occurred in members of Han-ok by field investigation. The noticeable defects were wood cracks, gaps that developed between wood pillar and wall or wood window frame and tenon joints. The most common biological defect was blue stain which was created in log. The mold generation was observed on exterior wood and wall which get wet by precipitation. The gaps between members of Han-ok pointed out as defect that is urgently improved by residents of Han-ok. The reason is mainly due to poor of insulation in winter by bad confidentiality. The maintenance work of defect such as gap was conducted personally. As a result, the repair parts were ugly for unfamiliar repair work.

This paper presented a literature review and investigation analysis results of total 19 present guide book and provisions of maintenance and management system in existing railway bridges to development of urban maglev track structures inspection manual. This research carried out a cooperated research subject 3-1, development a design code and maintenance and management inspection manual for urban maglev track structures, of the Center for Urban Maglev Program. Three types of track structures were includes as a major analytical parameter together with railroad, high speed railroad, subway and light rail transit. Bridges were analyzed a general rules, investigation, evaluation, repair and strengthen method as a key aspect. And rail were analyzed examination and maintenance also. This analysis results show that the track structures evaluation are based on the test and examination results, and repaired or strengthened consideration of deterioration, track irregularity and materials according to provision requirements.

최근 건설분야에서는 시설물의 사용을 극대화하기 위한 유지관리분야에 많은 관심이 집중되고 있는 추세이며, 특히 여러 시설물 중 교량과 같은 경우는 일반인의 사용빈도가 많으므로 시공상의 결함이 발생할 경우, 치명적인 피해는 물론 많은 경제적인 손실이 예상되는 부분이라 할 수 있다. 본 연구에서는 교량 시설물의 안전한 사용과 품질향상을 위해 국내 중소규모 교량에 대한 유지관리 현황 및 교량 관리시스템을 분석하여 새로운 형태의 유지 관리시스템인 BF\_IETM (Bridge Facility\_Interactive Electronic Technical Manual)을 제안하여 그 활용효과를 살펴보았다. $BF\_IETM$은 그 이름에서 알 수 있듯이 일반 IETM의 기능과 역할을 포함하고 있는 것으로, 기존의 종이 기반의 건설기술문서를 컴퓨터를 이용한 전자문서체계로의 전환을 이룸과 동시에 첨단의 정보기술매체를 통한 시설물의 유지관리 업무 활동을 지원할 수 일도록 구성된 시스템이라 할 수 있다.

Port structures are one of the important infrastructure of the nation. To ensure safety and extend lifetime of the existing port structures, it is necessary to develop proper maintenance program. In this study, port inspection manual for pier type structure are developed. The flow of inspection program is designed and defect type for each component of wharf is classified. Also systematic method of rating and evaluation is developed together with conceptual design of port maintenance data base system.

In this paper, the maintenance training manual of EV vehicle was produced by utilizing digital twin technology and various sensors such as IR-based light house tracking and head tracker. In addition, through digital twin technology and VR to provide high immersiveness to users, sensory content creation technology was secured through animation and effect realization suitable for EV vehicle maintenance situation. EV vehicle maintenance training manual is 3D engine programming and real-time creation of 3D objects and minimization of screen obstacles and selection of specific menus in virtual space in the form of training simulation. In addition, automatic output from the Head Mount Display (HUD), EV vehicle maintenance and inspection, etc., user can easily operate content was produced. This technology development can enhance immersion to users through implementation of detailed scenarios for maintenance / inspection of EV vehicles" and 3D parts display by procedure, realization of animations and effects for maintenance situations. Through this study, familiarity with improving the quality of education and safety accidents and correct maintenance process and the experienced person was very helpful in learning how to use equipment naturally and how to maintain EV vehicles.

Purpose: This study examined the effects of manual lymph drainage (MLD) on edema and the quality of life (QOL) of lymphedema patients in the maintenance phase. Method: Forty five lymphedema patients, who had completed intensive decongestive therapy, were enrolled in this study. All subjects were assigned randomly to two groups: Experimental (MLD) group (n=23) and control (self-MLD) group (n=22). MLD by a specialist was applied with a comfortable pressure for 40~60 minutes in the experimental group and self-MLD was carried out by the control group 5 times a week for 2 weeks. The % edema and a SF-36 questionnaire were used to measure the decrease in edema and the QOL. A paired t-test was used to compare the period, and an independent T-test was used to compare experiment and control groups. Result: The % edema was significantly lower in the experimental group after MLD (p<0.05). The physical, vitality, and mental health scores of the experimental group was significantly higher than those of the control group (p<0.05). Conclusion: TMLD by a specialist in the maintenance phase is effective in reducing the % edema and enhancing the QOL of lymphedema patients. Further studies will be needed to determine if there are differences in the effects of many types of treatment methods in the lymphedema treatment.
