다양한 전자제품의 조작법을 빠르고 정확하게 학습하는 것은 일상적이고 중요한 과제가 되었다. 특히 소프트웨어는 여러 제품들의 통제 및 조작에서 핵심적인 지위를 차지하고 있다. 본 연구는 기존 학습연구에서 중요한 변인으로 연구되어온 학습방법, 학습계획, 과제난이도가 소프트웨어 학습에 미치는 영향을 검증하였다. 실험1에서는 2 (학습방법: 경험적 vs. 언어적) ${\times}$ 2 (학습계획: 간격 vs. 덩이진) ${\times}$ 2 (난이도: 쉬움 vs. 어려운)의 피험자간 요인설계를 사용하여 각 조건에서 참가자들이 윈도우 무비메이커를 사용하여 파일을 조작하는 방법을 학습하는 실험을 실시하였다. 그 결과 학습계획에 따른 수행의 차이는 발견할 수 없었으나, 언어적 학습보다 경험적 학습에서 참가자들은 더 빠르게 평가과제를 완료하였다. 특히 과제난이도가 높아질 경우 참가들은 언어적 조건에서 경험적 조건보다 두드러진 수행저하를 보였는데, 이는 과제가 어려워질수록 경험적 학습이 효과적인 학습방법이 라는 것을 시사한다. 즉 소프트웨어 학습에서 간단한 조작의 경우에는 매뉴얼 혹은 지시문의 형태로 구성된 언어적 학습으로 충분하지만 어려운 과제의 경우에는 체험 프로그램이나 투토리얼 모드를 통해 학습하는 것이 효과적일 것이다. 추가실험에서 난이도 증가에 따른 언어적 학습의 선형적 이득을 확인하기 위해 난이도를 3단계로 세분화하여 검증하였으며 (실험 2) 학습계획의 효과를 확인하기 위해 학습시행간 간격을 증가시켰으나 (실험3) 유의미한 결과를 발견하지는 못했다.

This study proposes JPT(Job-Pair Tardiness) that choose operation to be expected to generate better schedule consequence in comparing schedulable operation sets in pair to minimize total tardiness evaluation function in performing scheduling. In result of comparison with existing assignment rules. JPT generates better solution than most other rules in all kinds of problems. So it is anticipated that this is used for initial solution of heuristic and is used for finding more improved solution.

This study develops a dynamic scheduling model for parallel machine scheduling problem based on genetic algorithm (GA). GA combined with discrete event simulation to minimize the makespan and verifies the effectiveness of the developed model. This research consists of two stages. In the first stage, work sequence will be generated using GA, and the second stage developed work schedule applied to a real work area to verify that it could be executed in real work environment and remove the overlapping work, which causes bottleneck and long lead time. If not, go back to the first stage and develop another schedule until satisfied. Small size problem was experimented and suggested a reasonable schedule within limited resources. As a result of this research, work efficiency is increased, cycle time is decreased, and due date is satisfied within existed resources.

Recently the technical advances and complexities have generated much of the difficulties in managing the project resources, for both scheduling and costing to accomplish the project in the most efficient manner. The project manager is frequently required to render judgments concerning the schedule and resource adjustments. This research develops an analytical model for a schedule-cost and risk analysis based on visual PERT/CPM. We used a three-step approach: 1) in the first step, a deterministic PERT/CPM model for the critical path and estimating the project time schedule and related resource planning and we developed a heuristic model for crash and stretch out analysis based upon a time-cost trade-off associated with the crash and stretch out of the project. 2) In second step, we developed web-based risk evaluation model for project analysis. Major technologies used for this step are AHP (analytic hierarchy process, fuzzy-AHP, multi-attribute analysis, stochastic network simulation, and web based decision support system. Also we have developed computer programs and have shown the results of sample runs for an R&D project risk analysis. 3) We developed an optimization model for project resource allocation. We used AHP weighted values and optimization methods. Computer implementation for this model is provided based on GUI-Type objective-oriented programming for the users and provided displays of all the inputs and outputs in the form of GUI-Type. The results of this research will provide the project managers with efficient management tools.

In this paper, we analyze the procedure of the design manager for the enhancement of the hull production design process by use of the simulation method. Normally, design manager assigns design jobs according to various methods and estimates the corresponding results. When the construction drawing which is the output of the detail design where a design is dealt by zones, the design manager identifies blocks and analyzes their work difficulties, and assigns jobs to design engineers who are different in capabilities. These processes including the design engineer who can be modeled with man-hours evaluation model are represented in detail as a simulation model. As the high-level modeling for the discrete-event system, we use Event Graph model. And we implemented the simulation using Simkit which is open simulation engine for the discrete-event system. We made the simulation scenario to be written by a user in the scenario generator which is separated from the simulation model, and made the simulation result to be visualized in the form of Gantt chart in a Web. In the scenario of the irregular issuance for various construction drawings which contain different numbers of blocks, we performed the Monte-Carlo simulation according to various assignment methods to find the assignment result that satisfies the mid-term schedule.

In Korea, telemedicine is still under the beginning stage, but we expect that the developing 'Information Highway' will make this technology more common place and more easily used in coming soon. Currently, three hospitals are providing telemedicine services with their subsidiary hospitals which are far away from their remote place. However, the fee schedule of telemedicine services are not well-settled down, of course not reimbursed through current health insurance system. This study aims to develop new payment system for medical services provided through telemedicaine system. To design appropriate fee schedule for telemedicine services, we, first, review the current insurance payment system and telemedicine system both in domestic and foreign countries focusing on its payment system. A framework of telemedicine payment system is proposed in following steps based on information we acquired from this stage. Second. We decide the span of cost items which should be covered by telemedicine payment scheme. In hear, we suggest payment method for telemedicine services should be designed as dual structure which are telemedicine fee that should be reimbursed through payment scheme and any costs related to capital investment that should not be covered by payment system. Which is, payment system for telemedicine services should cover only service-related costs and any costs related to capital investment should be generated through third party such as government, health insurance association, etc. Finally, we suggest new fee schedules for telemedicine services. The key issues on developing telemedicine fee schedules are related with the determination of appropriate additional rate($\alpha$). The reasonable additional rate($\alpha$) must determine through careful evaluation of any additional efforts(e. g. : additional work hours which are related to providing telemedicine services). This study shows the process of how to determine appropriate additional rate($\alpha$).

To curb a rapid increase in expenditures for pharmaceuticals, the Korean government introduced a positive list system and a negotiation process for drug prices at the end of 2006. Economic evaluation of pharmaceuticals has begun to have a pivotal role in the listing and pricing of drugs for the Korean National Health Insurance. There are some points to discuss regarding the use of economic evaluation in the listing and pricing in the context of the Korean system. First, the listing and pricing processes have been fragmented, evoking complaints from pharmaceutical companies and delaying the access of new drugs to patients. Second, there is a concern that the positive list system may limit the range and availability of drugs for patients to choose for treatment. Third, the time schedule for de-listing of existing drugs may not be realistic. Fourth, it is not always easy to provide reliable evidence of cost-effectiveness due to a lack of materials. Fifth, there is no consensus on the range of the ICER (incremental cost-effectiveness ratio) acceptable to the Korean society. In conclusion, in the near future, it will be necessary to evaluate the achievements that the economic evaluation has provided to the Korean society.

This research examined the work performance by consumer counselors, evaluations of their counseling work, the level of their satisfaction, and willingness to sustain consumer counseling work among Consumer Agencies and also identified the variables influencing the evaluation scores on those. The results were summarized as follows. First, the evaluation scores on the work performance of consumer counseling were generally high and they turned out to be generally satisfied with their work. On the other hand, most counselors responded that they would continue their counseling work. Second, there were differences in evaluation scores about speed and specialized area of counseling among Consumer Agencies. Counselors who worked for the Korea Consumer Protection Board recorded high scores in those both criteria. There were differences in the willingness of counselors to continue their counseling work among Consumer Agencies, too. Third, the evaluation scores in six areas of counseling tasks were high when the degree of satisfaction of counselors were high or when agencies treated the counseling important. Fourth, when counselors earned more salaries and owned the experience of in-firm training and when the Consumer Agencies highly valued counseling as consumer tasks, the degree of satisfaction among counselors increased. Finally, when counselors were old, major in consumer science, and held regular work-schedule, they exhibited high degree of satisfaction in their counseling work and they showed greater willingness to sustain their counseling work.
