Purpose: To identify the degree of users' satisfaction with Nursing Information System. Methods: The study is a survey of users' satisfaction with Nursing Information System. The subjects of the study are 300 nurses who use the Nursing Information System at least for 6 months or longer; data was collected from August 26th to September 1st, 2005. The collected data was analyzed on SPSS 12.0. Results: The results showed that there are noticeable differences in the degree of satisfaction among the users using the Nursing Information System depended on the subjects' marital status, working department, job title, types of computer training and other facts, such as individual's ability of using the system finding necessary references. Nursing records (including administration and prescription of medicine) was chosen to be the priority for the recognition of the Nursing Information System; for motivation on establishment of Nursing Information System was the efficiency of work; and for any problems or troubles with the Nursing Information System was the delayed work due to the system-suspension. Conclusion: The study implied that Nursing Information System have improved and effective Nursing practice.

By the effect of globalism and information the workplace environment is complicated and diversified little by little. The job stress due to the life style, the idea and culture, and the automated facility system etc. is to a tendency which compared to increase more. It will not be able to prevent a industrial accident basically because the oriental and western life style is different. Therefore this paper presents the Korean life change unit model through statistical testing in order to minimize industrial accident with the proposed life change unit factors on the workers living In the middle area. Finally, the analytical result of this paper can be easily used in order to minimize the industrial accidents by the job stress with the worker and the occupational safety & health manager in real fields.

Lot-streaming is the process of splitting a job (lot) into a number of smaller sublots and then scheduling these sublots in order to accelerate the completion of jobs in a multi-stage production system. Anew genetic algorithm (NGA) is proposed for an-job, m-machine, equal-size sublot lot-streaming flow shop scheduling problem with delivery windows in which the objective is to minimize the mean weighted absolute deviation of job completion times from due dates. The performance of NGA is compared with that of an adjacent pairwise interchange (API) method and the results of computational experiments show that NGA works well for this type of problem.

In this paper, we consider a planning problem arising from printed circuit board manufacturing industries. Given a set of several types of PCBs, component feeders and surface mounting machines in series in a PCB assembly line, the problem is to define the feeder allocation and job sequence with the objective of minimizing the total operation time of the line. We formulate the problem as a mathematical model. And, the problem is proven to be NP-hard, so a genetic algorithm is developed. Finally, we give test results to evaluate the performance of the genetic algorithm.

In this paper load redistribution algorithm to allow fault-tolerance by redistributing the workload of n failure nodes to the remaining good nodes in distributed systems are investigated. To evaluate the efficiency of the algorithms a simulation model of algorithms is developed using SLAM II simulation language. The job arrival rate service rate failure and repair rate of nodes and communication delay time due to load migraion are used as parameters. The result of the simulation shows that the job arrival rate failure and repair rate of nodes do not affected on the relative efficiency of algorithms. If the communication delay time is greater than average job processing time algorithm B is better. Otherwise algorithm C is superior to the others.

Under the current wave of globalization, engineering programs in Korea are determined to adopt an Accreditation System for Engineering Education, which is inevitable to acquire competitiveness in the world market. To meet the needs of engineering students to pursue their career as internationally qualified engineer, a development of tailored English course for them is needed. I tried to develop a Technical English syllubus as an ESP(English for specific purpose) course for engineering students based on the job description provided by O'NET(Occupational Information Network). O'NET describes and defines what kinds of abilities are needed for various workers, including engineers. Mechanical Engineer type is selected for research and 17 abilities are listed to be the most needed abilities which are over 50% in importance score and 6 language related abilities are listed among them, which shows the importance of language abilities in the engineering job sites.

Workforce information is important in production planning because production planning requires matching a production unit's capacity to loads of assignments. However, tracking and managing workforce information such as skills and accident history is not an easy job. This paper describes a prototype database system for a workforce database system that employs RFID technology. This system tracks daily workforce production capacity on sites. A pilot project is described to explore the benefits and possibility of using radio-frequency identification (RFID) to track and manage workforce information, and is followed by the results of a survey to identify benefits. In addition to the survey identifying the benefits of the database system, the paper also presents a list of challenges through a series of interviews.

Autonomous mobile robot provide many functions such as sensing, processing, and driving. For more intelligent jobs, more intelligent functions are to be added and the existing functions may be updated. To execute a job autonomous mobile robot has a information of surrounding environment. So, robot uses sonar sensor, vision sensor and so on. Obtained sensor information is used map generation. This paper is focused on map generation using stereo vision system.

빠른 웹 정보의 변화에 잘 대응하기 위해서는, 사실과 지식이 실제로 유효한 시간과 장소들도 함께 표현하고 그들 간의 관계도 추론할 수 있도록 웹 기술의 확장이 필요하다. 본 논문에서는 그동안 소규모 지식 베이스를 이용한 실험실 수준의 정성 시간 추론 연구들에서 벗어나, 웹 스케일의 대규모 지식 베이스를 추론할 수 있는 병렬 정성 시간 추론기인 MRQUTER의 설계와 구현을 소개한다. Hadoop 클러스터 시스템과 MapReduce 병렬 프로그래밍 프레임워크를 이용해 개발된 MRQUTER에서는 정성 시간 추론 과정을 인코딩 및 디코딩 작업, 역 관계 및 동일 관계 추론 작업, 이행 관계 추론 작업, 관계 정제 작업 등 몇 개의 MapReduce 작업으로 나누고, 맵 함수와 리듀스 함수로 구현되는 각각의 단위 추론 작업을 효율화하기 위한 최적화 기술들을 적용하였다. 대규모 벤치마킹 시간 지식 베이스를 이용한 실험을 통해, MRQUTER의 높은 추론 성능과 확장성을 확인하였다.
