A systematic educational program evaluation system for continuous quality improvement in undergraduate medical education is essential. Monitoring and evaluation (M&E) are two distinct but complementary processes referred to in an evaluation system that emphasizes formative purpose. Monitoring involves regular data collection for tracking process and results, while evaluation requires periodic judgment for improvement. We have recently completed implementing an educational evaluation using the M&E concept in a medical school. The evaluation system consists of two loops, one at the lesson/course level and the other at the phase/graduation level. We conducted evaluation activities in four stages: planning, monitoring, evaluation, and improvement. In the planning phase, we clarified the purpose of evaluation, formulated a plan to engage stakeholders, determined evaluation criteria and indicators, and developed an evaluation plan. Next, during the monitoring phase, we developed evaluation instruments and methods and then collected data. In the evaluation phase, we analyzed results and evaluated the criteria of the two loops. Finally, we reviewed the evaluation results with stakeholders to make improvements. We have recognized several problems including excessive burden, lack of expertise, insufficient consideration of stakeholders' evaluation questions, and inefficient data collection. We need to share the value of evaluation and build a system gradually.

본 연구에서는 산업체에서 대체 세정제를 객관적이고 체계적으로 선정하는데 도움을 주고자 여러 가지 세정성 평가방법을 실험을 통하여 비교 평가하였다. 세정성 평가방법으로는 중량법, OSEE (optically simulated electron emission)법, 접촉각법과 FTIR, UV-VIS, HPLC와 같은 정밀분석기기를 이용한 분석법을 사용하여 flux, solder, grease 등의 오염물질에 대한 세정성 평가를 수행하였다. 그 결과 중량법은 쉽고 간단하게 세정제의 세정효율을 측정할 수 있었지만 중량측정의 한계로 정밀측정이 어려웠다. 반면에 OSEE법은 세정제의 세정성 평가를 빠르고 정밀하게 수행할 수 있었다. 접촉각 측정법은 피세정물 표면에 오염물질과 세정제에 의한 얇은 친유성 막의 형성으로 인하여 접촉각 변화에 영향을 주기 때문에 세정성 평가에 특별한 주의가 요구되었다. 중량법으로 수행하기 어려운 정밀세정성 평가의 경우 UV-VIS, FTIR, HPLC와 같은 정밀분석기기를 이용하여 피세정물에 잔류한 flux, solder, grease 등의 극미량의 오염물을 특수 용제로 추출하여 아주 작은 농도의 오염물을 정량분석할 수 있었다.

Background: An appropriate use of hospital beds can improve productivity of hospital significantly. The authors' previous study revealed that approximately one third of Korean hospital bed days and one sixth of admissions were inappropriately used, when it was measured by Appropriateness Evaluation Protocol(AEP) and Delay Tool modified into Korean situation by the authors. This study aims to evaluate applicability of the instruments in a new hospital. More specifically the study aims to measure appropriateness of the instruments used by newly trained nurse reviewers at a new hospital setting. Methods: In order to evaluate applicability of these instruments, agreement rates of the scores recorded by newly trained nurse reviewers with by skilled nurse reviewer and also compared with the scores recorded by physician's implicit decision were assessed. Agreement rates were derived from concurrent application of AEP and Delay Tool to 52 admissions and 104 patient days from internal medicine, pediatrics, and general surgery of one university hospital. Overall agreement rate, specific nonacute agreement rate, and kappa statistics were used to indicate level of agreement. Results: Overall agreement rates on appropriateness between newly trained nurse reviewers and skilled nurse reviewer were 100% in admission and 98% in bed days. Overall agreement rates on reason for inappropriateness between newly trained nurse reviewers and skilled nurse reviewer were 96% in admission and 91% in bed days. Overall agreement rates between newly trained nurse reviewers and physician reviewer were 86% in admission and 87% in bed days. Conclusion: Results indicated that AEP and Delay Tool were applicable to a new hospital in detecting inappropriate utilization of beds and reasoning of the inappropriateness. These instruments could contribute to enhance efficiency of hospital use, through continuous monitoring of level of inappropriate hospital use at national or individual hospital level.

Objectives: The purpose of the study was to investigate the influences of job performance of dental hygienists on emotional labor evaluation. Methods: A self-administered questionnaire was completed by 203 dental hygienists working at dental hospitals and clinics in Gyeongnam and Busan from May 2014 and March 2015. The study instruments comprised general characteristics of the subjects (9 items), job performance competency (44 items), and emotional labor evaluation (29 items) by Likert 5 point scale. Data were analyzed by SPSS 21.0 program and AMOS 18.0 program. Results: Those who had turnover intention showed higher scores in the dental treatment cooperation category and overall job performance than those who had not. Higher job performance was shown in those who had more work experience and higher salary. The scores of emotional labor evaluation were higher in the group of higher salary and team and department leaders. The job performance had a significant impact of the emotional labor evaluation. Conclusions: The job performance of dental hygienists had a significant influence on the emotional labor evaluation. Psychologic stress by work caused the dental hygienists to have depression and lower quality of life.

This paper introduces the environmental economic studies in Korea, focused especially on the environmental regulation policy and valuation of environmental resources in Korea. It can be seen from this survey that the Korean environmental economists have had most of their interests in socially hot issues such as the evaluation and alternatives of the existing environmental policy instruments, and the impacts of both the environmental regulation and greenhouse gas reduction policies, as well as economic valuation of environmental assets including air, water, and ecosystem. We need more intensive research on issues of the evaluation of individual public investment, enforcement, transaction costs and income distribution and inter-generational equity. More attention should also be paid to the valuation methods and environmental data.

Purpose: The purpose of this study was to describe the degree of perceived health status, depression and quality of life(QOL) and to examine the relationships among these factors in breast cancer survivors. Methods: The subjects were 105 women with mastectomy after breast cancer diagnosis who were in the out-patient department of surgery at SNUH in Seoul. Data was collected using self-report instruments. The instruments included 1-item for perceived health status, Chae and Choe's QOL scale for Korean breast cancer survivors, and Beck Depression Inventory(BDI) as well as socio-demographic and medical information. Data were analyzed with SPSS WIN 10.0 program. Results: The levels of perceived health status and QOL were moderate. Mild depression was found on the BDI. QOL and depression showed a negative correlation(r= -.598), whereas QOL and perceived health status was correlated positively(r=.370). Depression, perceived health status, and time since diagnosis accounted for 47.4% of variance of the QOL. Depression was the most significant predictor of QOL in breast cancer survivors. Conclusion: Breast cancer survivors may experience depression and alteration in QOL. Future nursing research should be directed toward the implementation and evaluation of interventions that promote QOL and decrease depression in breast cancer survivors.

Purpose: This study was designed to explore and compare the self efficacy, social support, and quality of life between middle-aged Korean and Chinese women. Methods: The sample included 430 (Korean: 220, Chinese: 210) middle-aged women. Study instruments were the Self Efficacy Scale developed by Shere et al (1982), the Social Support Scale modified and based on Interpersonal Support Evaluation List (ISEL) developed by Cohen and Hoberman (1983), and The Quality of Life Scale (SF-36) developed by Ware and Book (1981). Data were analyzed by SPSS/WIN 16 version. Results: Korean women reported more self efficacy and better quality of life than the Chinese women. The quality of life scores between middle-aged Korean and Chinese women showed a statistical significant difference. Self efficacy and quality of life scores reported by middle-aged Korean and Chinese women were below the reported standards of the instruments. In contrast to the other scores, Chinese women reported more social support than Korean women. Conclusion: The findings add to the body of literature about Chinese and Korean middle aged women. Additional research is needed to explain the differences among the two groups but the findings can inform the practicing nurse who works with these populations.

Objective: This study was to resolve the limitations of the experimental environment and to solve the shortcomings of the method of measuring human gait characteristics using optical measuring instruments. Design: A cross-sectional study. Methods: Fifteen healthy adults without a history of orthopedic surgery on the lower extremities for the past 6 months were participated. They were analyzed gait variables using the smart guide and the 3D image analysis at the same time, and their results were compared. Visual-3D was used to calculate the analysis variables. Results: The reliability and validity of the data according to the two measuring instruments were found to be very high; gait speed(0.85), cycle time(0.99), stride time of both feet(0.98, 0.97) stride legnth of both feet(0.86, 0.88) stride per minute of both feet(0.99, 0.96), foot speed of both feet(0.90, 0.91), step time of both feet(0.77, 0.71), step per minute(0.72, 0.74), stance time of both feet(0.96, 0.97), swing time of both feet(0.93, 0.79), double step time(0.81), initial double step time(0.84) and terminal step time(0.76). Conclusions: In the case of the smart insole, which measures human gait variables using the pressure sensor and inertial sensor inserted in the insole, the reliability and validity of the measured data were found to be very high. It can be used as a device to replace 3D image analysis when measuring pathological gait.
