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.

In this study various cleaning evaluation methods were tested and comparatively evaluated to help cleaning industry. In order to select alternative cleaning agents objectively and systematically, various cleaning evaluation methods such as gravimetric, optically simulated electron emission (OSEE), contact angle, and analytical instrument methods were employed for cleaning contaminants such as flux, solder and grease. The analytical instruments used in this work were Fourier transform infrared spectroscopy (FTIR), ultraviolet visible spectroscopy (UV-VIS) and high performance liquid chromatography (HPLC). The gravimetric method was able to measure cleaning efficiencies easily and simply, but it was not easy to analyze them precisely because of its limitation in the gravimetric measurement. However, the OSEE technique was able to measure quickly and precisely the clean ability of cleaning agents in comparison with the gravimetric method. The contact angle method was found to be necessary for taking special precaution in its application to the cleaning evaluation due to possible formation of tiny organic film on the substrate surface which might be generated from contaminants and cleaning agents. In case of precision analysis that cannot be done by gravimetric method, fine analytical instruments such as UV-VIS, FTIR and HPLC could be used in analyzing trace amount of flux, solder and grease quantitatively, which were extracted from the surface by special solvents.

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.

Instrument flight simulators are used for training the interpretation and operation techniques for all kinds of aircraft instruments, cockpit procedures, etc., in order that pilots cope with the situations which can be occurred in actual flight. However, the simulators developed so far are concerned about operating in same environment to actual aircraft. And little researches concentrate on developing systematic training system for basic tasks and takeoff-landing procedures, and automatic evaluation methods on the training results. Therefore, in this paper, we propose implementation and evaluation methods for flight tasks such as tasks in flight, takeoff-landing procedures and course flight.

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.
