오피스 및 과학 분야의 문서 작업 등에서 XML의 사용이 보편화되고 협업이 요구됨에 따라 효과적인 XML 문서 병합 방법이 필요하다. 이에 대한 해결 방안으로 본 논문에서는 동일 원본 문서에 대한 다수 사용자의 편집 작업들의 병합을 위한 이론적 틀을 제시한다. 문서들의 병합시 문서 자체를 병합하는 기존의 방법들과는 달리, 사용자의 편집 작업을 원본 문서에 적용되는 일련의 편집 연산들, 즉 편집 스크립트로 표현하고 다수 사용자의 편집 스크립트들을 병합하고 원본 문서에 적용하여 문서의 병합 효과를 이루고자 한다. 이를 위해 삽입과 삭제연산으로 구성된 편집스크립트를 전제로 정적 편집 스크립트, 편집 스크립트의 간섭 및 충돌 등의 개념들을 정의하고 편집 스크립트들의 충돌 조건과 병합시 편집 스크립트 조정기법을 제안한다. 이 방법은 분산 환경에서 네트워크 부하를 줄이며 각 편집 작업의 의미가 보존되어 버전관리에 효과적이다.

Objective: The aim of this study is to investigate the roles and human resources of service design. Background: The definition of service design is not clear yet, also did not define in this study. I studied the components of service design which are roles and human resources. That is helpful to understand the definition of service design and to clarify the works in service design. Method: I compare the service design with user experience design. I empirically define the roles and human resources of service design. Results: The roles of service design are service strategy, research, service concept design, service specification, service architecture design, integrated communication design, integrated system design, integrated operation design, service evaluation, launch, operation, and knowledge management. Conclusion: We defined who works and what works in service design. Application: The results of this study help the clarification of service design.

Research on the development of key technologies of social work protection and content mashup tools has been carried out as an R&D project granted by the Korea Copyright Commission from 2013. The research aims to provide efficiency of the production environment of the secondary work of the digital contents as well as a systematic solution to the regulation-related problems. The essential features of the distribution management system for cooperative works developed though this study are the decision of the selling prices reflecting various license fee factors and the transparent distribution of the license fees. This paper represents a model which can automatically calculate the amount of the license fee in each derivative stage, independently of the license fee policies on each of the subsidiary contents when N-th works are producted on the basis of a previously approved first work.

In steel works, Locomotives and torpedo ladle cars are used to convey the smelted iron that comes out Blast Furnace to the steel-making mill. Above conveying vehicles are operated in all steel works area. And to trace their positions, after partitioned their areas, Automatic Vehicle Identification(RF-ID method) is installed on the railroad and identifies vehicle numbers. But AVI facilities have many problem that means that are too expensive, cost too much maintenance fee and inefficient management. This paper is to revamp those inefficient operations and state the status of operations of train positioning system, get to know what the problem is. And also when we use GPS to monitor and trace the vehicle position ...

Current domestic safety training in building demolition works are heavily relies on the limited number of experienced people and thus, it implies the demand of preparing the systematic program and stricter yardstick is soaring. Questionnaire survey and in-depth interview results with demolition engineers were analyzed adopting AHP methodology. Analysis results reveal that the most urgent items which required improving current safety training system are to increase investment level, prepare more structured training system and secure experts, and so on. In addition, field labors and managers strongly requested the improvement of environment-related safety matters. Based on the evaluation results, guidelines were suggested for the improvement of safety training system in building demolition works.

In the case of aviation maintenance work, several kinds of shift works are performed during day and night, and a lot of works are performed on the ramp due to the characteristics of the aircraft flight schedule. Maintenance workers are often exposed to the sun or in cold temperatures for aircraft maintenance works. The fatigue risk of the maintenance workers will be weighted. In particular, the work at night shift under normal biological rhythms can make maintenance workers feel sleepy during daytime work. It can also affect the safety of aircraft and individual workers. Accordingly, this study will consider fatigue-related previous researches in the field of aviation maintenance, review the effects of shift work, and how fatigue affects aviation mechanics during the day/night shifts. Considering these factors, we tried to present a plan that can minimize the fatigue of aviation workers through this study.

As construction projects are gradually getting larger and focusing on building skyscraper with the development of construction technology and the concentration of population in cities, the choice of the soil sheeting works is very important in terms of securing safety and economic feasibility. Further research is planned on the developed concrete guide-based continuous over lap pile method through the introduction of a system that automates vertical management, continuous improvement and supplementation so that the basement soil sheeting wall can be utilized as a building structure.

In this paper, we propose bandwidth management scheme to efficiently guarantee the QoS of various services on ATM based IMT-2000 networks. The proposed bandwidth management scheme consists of the call admission control to reduce a handoff failure probability and the scheduling scheme to efficiently allocate a time slot based on the QoS requirements in wireless links. The simulation results show that the proposed bandwidth scheme has better performance than the previous works in terms of the handoff failure probability and packet delay time.
