Purpose: To identify the effects of clinical practicum reinforcement program on nursing student's clinical competency and satisfaction in the ICU. Methods: The study utilized a quasi-experimental pretest-posttest research design. The participant was 76 senior nursing students, who were engaged in two week-long clinical practicum in ICU at the C university hospital in a G city, Korea. The clinical practicum reinforcement program was applied to the experimental group (n=39), while the control group (n=37) was involved in the conventional practicum program. The collected data were analyzed using descriptive analysis, $x^2$/Fisher's exact test, and t-test, ANCOVA with SPSS/WIN 18.0 program. Results: After 2 weeks' clinical practicum, the experimental group showed a statistically significant increase in the clinical performance abilities by self evaluation, when compared to the control group. Clinical instructor's evaluation on the student's clinical performance revealed that the experimental group showed higher level in nursing activity than that of the control group (p<.001). However, there was no significant difference between the two groups in terms of the satisfaction on the clinical practicum program except the learning guidance and the evaluation. Conclusion: The clinical practicum reinforcement program is an effective one for improving the student's clinical competency.

Simulation of daylighting by computer program is a method to avoid unnecessary efforts in manufacture of its testing models, to reduce its measuring tolerances and be able to provide variations of various weather conditions as well. Many simulation programs on daylighting have been released freely or commercialized for selling, however, a demonstration of their availability and validity as a tool for evaluating daylighting performance is required since each one has its own characteristics. The objectives of this study lie in suggesting an application method of evaluation tools and demonstration of limits and characteristics so as to more easily determine the daylightingperformance in the very initial stages of planning for an arbitrary office space in which windows with daylight access are built. We produced scale model of the general light inducing type side lighting with lightshelfand ceiling, and the luminance (at 78 measuring points) and illuminance (at 84 measuring points) were measured in a clear sky. And a comparison of the measured values and the calculated values from a computer simulation using the Lightscape program was performed.

The performance evaluation technique of a heat exchanger is described by using a transient response analysis for the determination of an average heat transfer coefficient. The model using a finite difference method can accommodate arbitrary inlet fluid temperature as well as longitudinal conduction. Temperature histories are obtained from the experiments at the inlet and outlet of test core. Heat transfer coefficient and friction factor of the plate array are obtained in short times using the data reduction program of transient response analysis in the single-blow method. The results agree very well with theoretical results. It is shown that the rms deviations are very small and the performance evaluation technique gives rapid and accurate results.

A software developer can use a performance evaluation tool to elevate development speed and improve qualify of softwares. But, evaluation results that most performance evaluation tools offer are complicated strings. Therefore, a developer cannot intuitively understand the meanings of the results and must make much times and efforts in analysing the result. In this paper, we propose a report view generator that can transform and provide the text-based performance evaluation results for softwares with various graphic-based views. Our proposed generator consists of a screen generator that creates a structural XML document about the text-based performance evaluation results and a log analyzer that makes various report view through the created XML evaluation document. Because the XML evaluation result document can express the result information structured according to performance evaluation items for resources of softwares, it can have flexibility in offering and integrating the result information for the items. Through the suggested report view generator, developers can intuitively understand and analysis performance evaluation results of embedded software. And they can easily and quickly improve software quality and improve development efficiency of softwares.

Purpose: This paper presents the development process and the final contents of the sellf- management education program integrated with exercise training (Healthy Aging Happy Aging, HAHA program) for community residing older adults with chronic diseases. Methods: The program evaluation methodology was applied which is an interactive program development process based on needs assessment, formative evaluation, process evaluation and outcome evaluation. The program was developed and revised while the program was implementing to 22 hypertension (HT) and 32 diabetic (DM) participants. Results: The final program has two sub-programs for HT and DM participants utilizing self-efficacy resources. They share four common components; 1) health screening of exercise risks, 2) weekly 1-hour group self-management education classes, 3) biweekly 1-hour group exercise training and 4) a mid-term individual counseling. Both sub-programs were 12-weeks long but have different education and exercise contents. Participants-rated mean satisfaction scores were 3.47/4 and 3.61/4 for HT and DM program respectively. Attendance rate were 83.1% ~ 92.3% for the classes. Conclusion: The HAHA program developed by multidisciplinary team which reflected participants needs was accepted well by participants evidenced by high attendance rate and perceived satisfaction level.

The clinical practice program for home care nurses was implemented in June 1994, to help to set up a hospital-based home care system in the Kwangju City area as a collaborative work between the Department of Orthopedic Surgery at Chunnam University Hospital and Chunnam University School of Nursing. Under the developed clinical practice strategy, the eight week training was given to five licensed home care nurses who had completed Part I and II of the home health care nursing practicum from June 1994. The purpose of this descriptive evaluation study was to identify the effectiveness of the clinical practice program for home care nurses specialized in the area of patient care for people with musculoskeletal function impairment. As a method in data analysis, data triangulation was used in the five home care nurse case evaluations. The variety of data analyzed include confidence score by home care nurse self-evaluation, patient and family member satisfaction scores, and competency score by preceptor evaluation. The study findings revealed that an increase rate in nursing performance didrate necessarily coincide with an increase not in competency score and also, not with the patient /family member satisfaction scores. And an order derived from the clinical performance scores of five home care nurses corresponded to those from three measurements-competency score, patient satisfaction score, and family member satisfaction score. However, it differed from the order associated with the confidence score. Consistency derived from the three objective evaluation methods may lead to the possibility that the level of competency measured by educator can be further explained by the levels of patient/family member satisfaction. The salient finding of this study was that, in case of nurse A who have had little clinical experience in the orthopedic patient care, there was a significant increase in the level of confidence and competency in subscale of professional skill with the home care clinical practice. Therefore, the effect of the clinical practice program would be successful for nurses who have had little experience in the area of specialization. The study results suggest that there might be some time difference in the development of cognitive sense (confidence) in performance and actual clinical performance (competency). In future research, relationships between the confidence and competency score, and between the confidence score and the patient satisfaction score should to be measured in different time frame to achieve a better explanation power of the study outcome.
