Purpose: This study was aimed to develop a tool for evaluating nurses' performance by using Balanced Score Card (BSC) in hospital units. Methods: Preliminary survey was done in 10 hospitals to investigate evaluation criteria for nurses' performance. For the main study, each of 14 nursing managers evaluated 2 nursing units (total of 28 nursing units) to verify the sensitivity of the tool criteria. The evaluation result drawn from the preliminary BSC tool was analyzed to verify the sensitivity and validity of the tool. Results: As a result, nurses' performance evaluation tool consisted of 4 categories, 8 objectives, and 14 criteria was developed. Conclusion: The BSC tool for nurses' performance evaluation provides meaningful data in evaluating nursing performance in hospital units.

Web sites on the internet are excellent information resources for the consumers to gain health care knowledge. Especially web sites related to child-care more increase recently. But a concern has emerged for the quality of contents contained on the child-care web sites. Lack of evaluation criteria have led to inaccurate and misleading child-care related publications on the Internet. For evaluating the quality and reliability of child-care related information on the Web, rating tool should be provided and developed. So, this article reviewed and investigated the elements to evaluate child-care sites on the internet. On the basis of the review of articles and the validity test about the contents, 16 preliminary items including purpose, contents, authority, feedback, design developed. Through the pilot study that apply the preliminary evaluating criteria to 20 evaluating criteria for child-care web sites developed. This evaluating criteria have 24 items and that were categorized to purpose(2 items), detail of contents(16 items), authority(2 items), feedback(2 items), design(4 items). The result of this study suggest that the evaluation criteria for child-care web sites may be useful for evaluating the quality of child-care web sites.

Method: The data was gathered from April 15, 2002 to June 14, 2002. The tool proceeded in six steps according to Bloch's framework. Result: The results of this study are as follows: 1) The quality evaluation tool for neurosurgery ICU consisted of 25 standards and 138 criteria. The quality evaluation tool for ward consisted of 27 standards and 144 criteria.; 2) The content validities of the tools for neurosurgery ICU and ward were 0.96 and 0.98, respectively.; 3) The Pearson coefficients for evaluating the interrated reliability of the tools for neurosurgery ICU and ward were r=0.9106 (p<0.1) and r=0.8807 (p<0.1), respectively.; 4) The ranges of corrected item-total correlations for evaluating the construct validity of the tools for neurosurgery ICU and ward were 0.0279~0.9354 and 0.0174~0.9682, respectively.; And 5) The ranges of Cronbach's ${\alpha}$ reliabilities for evaluating the internal consistency reliability of the tools for neurosurgery ICU and ward were 0.6040~0.8554 and 0.6212~0.9584, respectively. Conclusion: The tools developed in this study seem useful in evaluating the quality of nursing care for aneurismal subarachnoid hemorrhage patients at Hunt & Hess Grade I-III.

이 연구는 교육서비스 관점에서 MOOC의 질 평가를 위한 잠재모형을 도출하고 신뢰롭고 타당한 MOOC 질 평가도구를 개발하고 타당화하는 데 목적이 있다. 연구목적을 달성하기 위해 선행 연구결과에 기초해서, MOOC 평가 잠재모형(4개 요인과 8개 하위요인)을 도출하였다. 이 잠재모형을 토대로 18개 예비 평가문항을 개발한 후, 대학 원격수업 경험이 있는 학습자 138명을 대상으로 문항중요도 설문을 실시하였다. 수집된 136개의 자료를 활용하여 탐색적 요인분석 결과, 수집된 데이터에서 4개의 요인(체제적 학습 경험, 가치 경험, 가치 경험의 공동 창조, 고차원 학습경험)과 7개의 하위요인(실제성, 신뢰성, 확신성, 반응성, 조직환경 체계성, 프로그램 체계성, 학습자 지지의 체계성, 공동주도성)으로 추출되었다. 신뢰도 분석결과, 선정된 문항들은 각 척도를 구성하는 문항으로서 높은 내적합치도를 보였다. MOOC에 대한 평가도구는 타당하고 신뢰할 수 있다는 결론을 내릴 수 있다.

This study presents a methodology that efficiently evaluates and interprets the end-user computing capability in a total perspective in a computing environment. The evaluation system has an evaluation tool, evaluation method and process, and an interpretation system. The validity and reliability of the developed tool construct was verified by factor and reliability analysis with the application of SPSS software. The application and utilization of the developed system was confirmed by applying it to evaluating the computing competency of 316 workers in an enterprise and presenting its evaluation results. This will contribute to developing a methodology for totally evaluating and interpreting the end-user computing capability and improving their computing capability in industrial fields.

In this study, a new adhesion evaluating equipment and data processing methods were developed to overcome some limitations of existing evaluating equipment. Nano-diamond coated tool is a specimen of experiment. When applying frictional force and shear force on the specimen by a rotating polishing pad, delamination occurs at a moment. During each experiment, the vibration, load, and torque is obtained by accelerometer, loadcell and torque s+ kpensor. Frictional force and coefficient of friction are obtained by calculating torque and load. Based on FFT transformation, acceleration is processed and analyzed. As a result, the moment of delamination and the load at that time can be detected by the new developed equipment and measurement system. Finally, we call this load as an Adhesion force.

This paper gives an attempt to build a decision support tool linked with a simulation software called ARENA for evaluating and comparing the performance of the push and pull material driven strategies operating in the flow shop environment with a bottleneck resource as the shop's constraint. To be fair for such evaluation, the comparison must be made fairly under the optimal setting of both systems' operating parameters. In this study, an optimal-seeking heuristic algorithm, Genetic Algorithm (GA), is employed to suggest a systems' best design based on the economic consideration, which is the profit generated from the system. Results from the study have revealed interesting outcomes, letting us know the strength and weakness of the push and pull mechanisms as well as the effect of each operating parameter to the overall system's financial performance.

Background: The purposes of this study were to examine whether “Berg Balance Sale(BBS)” had influence on the improvement of stroke patient's balancing ability, and to identify whether the effects had significant differences to these three groups that different frequency of BBS evaluation. Subjects were divided into three groups, a daily evaluating group (n＝12), weekly evaluating group (n＝12), and group that evaluating when admit and discharge (n＝12). Methods: All patients were treated general neurorehabilitative physical therapy for daily during 4 weeks. All patients of these groups were evaluated balance function by using of BBS balance testing tool. Results: At the first week and after 4 weeks, balance function that of these groups was improved significantly (p<,05). Especially, daily evaluating group was improved the most. In the comparison differences between 3 groups, daily evaluating group and weekly evaluating group, daily evaluating group and group that evaluating when admit and discharge were exhibited differences significantly. But there was no significant difference between weekly evaluating group and group that evaluating when admit and discharge. Conclusion: According to the results as presented above, testing method, BBS is effects on stroke patient's balancing ability considerably. And if BBS which can apply evaluate balance function properly apply with conventional neurorehabilitative physical therapy, stroke patients would obtain significant effects on the improvement of balancing ability.

Recently, as the demand of small-sized precision parts is rising in precision industry such as mobile, automobile, optic. etc. the requirement of small-sized machine tool is increasing. Desktop machine tool define small-sized machine tool that is able to install in table. According to diminishing in size, Desktop machine tool is able to economize production cost by reducing work area and consuming electric power. But Desktop machine tool generates vibration in acceleration and deceleration modes by inertia force of moving part. Also vibration is generated when it move simultaneously two axis or three axis. Such generating vibration situation is reason of declining stiffness of machine tool structure because of smallizing in size. And this vibration has a large effect on precision of machining products. Therefore, evaluating of the control characteristic is necessary for minimizing vibration of machine tool as much as possible to accomplish precision machining of small-sized parts
