본 연구에서는 GUI환경을 제공하는 SIMULINK를 이용한 터보제트 엔진의 성능모사 프로그램을 새로이 제안하였다. SIMULINK 성능모사 프로그램에 의한 성능해석 결과는 기개발된 FORTRAN 성능모사 프로그램의 결과와 비교하였다. 비교결과 SIMULINK 프로그램과 FORTRAN 프로그램에 의한 결과 사이에 다소 큰 차이를 보이는데 이는 구성품간 조합방법의 차이에 기인한 것으로 추정되며, 추후 개선을 할 예정이다.

This study was a quasi-experimental study to confirm the effects of a memory training program using efficacy sources. The purpose was to develop an effective memory training program for elderly people and to identify the effects of the memory training program. This study was carried out between February 24 and July 18, 1999 and the subjects of the study were 102 elderly people who were participants at a welfare institute in Seoul. The experimental group (51) and the control group (51) were assigned by means of participation order. The control group was matched to the experimental group and was selected considering age, sex, and religion. The experimental group participated in the memory training program. The memory training program was based on the literature of Fogler & Stern (1994), Wang & Lee (1990), Lee (1991) and Lee (1993). The memory training program was given twice a week for two weeks with each program lasting two hours. Task centered memory self-efficacy was measured using the Memory Self-Efficacy Scale developed by Berry & Dennehey (1989) and Meta Memory was measured by the MIA developed by Dixon et al. (1988) Memory performance was measured by the word list developed by Cho Sung Won (1995) and the face recognition task (Face Recognition Task developed for this study). Data were analyzed by SPSS PC and the results are described below. 1. The experimental group which participated in the Memory Training Program showed higher task centered memory self-efficacy scores as compared to the control group (t=4.354, P=.0001). 2. The experimental group which participated in the Memory Training Program showed higher metamemory scores as compared to the control group (t=4.733, P=.0001). 3. The experimental group which participated in the Memory Training Program showed higher memory performance scores as compared to the control group (t=7.500, P=.0001). The memory performance involved an immediate word recall task, a delayed word recall task, a word recognition task, and the face recognition task. 4. In the experimental group, there was significant correlation between the task centered memory self-efficacy scores and the metamemory scores (r=.382, P=.006), but the correlation between the task centered memory self-efficacy scores and the memory performance scores and between the metamemory scores and the memory performance scores were not significant. The results showed that task centered memory self-efficacy, meta memory and memory performance improved following the Memory Training Program including the memory process, changes in memory with aging, and appropriate use of memory strategies. Memory Training Program is an effective nursing intervention for improving memory in elderly people and, also, in people with complaints of memory loss.

Purpose: This study was designed to determine visiting nurses' job performance and self confidence by career and number of visiting households. Methods: The subjects were 120 visiting nurses fully in charge of the visiting health care program working in 18 community health care centers, who were checked for 5 domains of visiting nurses' job, 39 tasks of job performance and self confidence. ANOVA test, Scheffe test and Pearson correlation coefficient were used for data analysis. Results: The level of job performance and self confidence indicated highest in understanding of the visiting health care program among 5 domains of visiting nurses' job. The level of job performance and self confidence indicated lowest in community resource connection. When nurses were classified by a career with approximately 5 years of working experience, nurses with a career of more than 5 years were highly significant. Job performance and self confidence were positively correlated. Conclusion: Based on the result of this study, it is recommended that the education program for newly hired nurses should be differentiated from that for visiting nurses with a career in order to improve quality of the visiting nursing program and capacity of residents' health care.

A genetic improvement program in Korea was implemented to improve the performance of Hanwoo cattle by generating livestock with genetically desirable economic characteristics. In particular, in response to external changes, such as the expansion of Free Trade Agreement (FTA), the livestock genetic improvement program has increased farm income by improving the productivity and quality of Hanwoo cattle. Using production cost data from Statistics Korea, the total input and output indices of Hanwoo feeding cattle from 2008 - 2021 were estimated and the growth and productivity changes were analyzed. The productivity change measures results were used to estimate the cumulative effects of the Hanwoo genetic improvement program on quality improvement, another purpose of the program, using a finite distributed lag model. The average annual increase in output (market weight) of Hanwoo was 0.9%. However, total input increased by 1.6%, resulting in a 0.6% decline in total factor productivity. In contrast, the Hanwoo genetic improvement program contributed significantly to the production of high quality beef, rather than contributing to improved productivity of the cattle. Hanwoo carcass weight, which is used as a performance indicator for the livestock genetic improvement program, has significantly improved and is projected to increase at a slower rate. The collective findings indicate the need for new performance indicators that can comprehensively indicate the performance of the genetic improvement of Hanwoo.
