Data stored in hospital information systems has a great potential to improve adequacy assessment and quality management. Moreover, an establishment of a data warehouse has been known to improve quality management and to offer help to clinicians. This study constructed a data mart that can be used to analyze antibiotic usage as a part of systematic and effective data analysis of infection control information. Metadata was designed by using the XML DTD method after selecting components and evaluation measures for infection control. OLAP-a multidimensional analysis tool-for antibiotic usage analysis was developed by building a data mart through modeling. Experimental data were obtained from data on antibiotic usage at a university hospital in Cheonan area for one month in July of 1997. The major components of infection control metadata were antibiotic resistance information, antibiotic usage information, infection information, laboratory test information, patient information, and infection related costs. Among them, a data mart was constructed by designing a database to apply antibiotic usage information to a star schema. In addition, OLAP was demonstrated by calculating the statistics of antibiotic usage for one month. This study reports the development of a data mart on antibiotic usage for infection control through the implementation of XML and OLAP techniques. Building a conceptual, structured data mart would allow for a rapid delivery and diverse analysis of infection control information.

Background : Quality of professional nursing care is the most essential factor for survival and growth of nursing profession. Then, nursing professionals have responsibility for the evaluation of quality of professional nursing care. The purpose of this study was to develope an evaluation tool of nursing care for patients received gastrointestinal surgery with general anesthesia. This study was a primary work for the developement of a computer program for the evaluation of nursing care. Methods : This study was done through some consecutive steps. They were (1) Developement of items for the tool (2) Developement of an evaluation tool of nursing care quality for the G-I surgery patient (3) Test of reliability and validity of the tool. Two groups of experts and expert pannels who had much experience of the QA and the care of G-I surgery patients participated for developement of the items. 85 nursing records were used for the test of reliability and validity of the developed tool. The evaluation tools were developed with two types of scoring, norm-referenced tool and criterion-referenced tool. Results The system of items for tool was evaluation area evaluation item-indicator. There were 7evaluation areas which contained 32evaluation items which contained 7lindicators. Evaluation areas 1, 2, 3, 4 were for the evaluation of process and 5, 6, 7 were for the evaluation of outcome of nursing care for G-I surgery patient. For the test of interrator reliability, correlation coefficients of each scores of items and intragroup correlation coefficients were calculated. The average correlation coefficients between two rators were 0.65, 0.54 and the intragroup correlation coefficient were 0.99 and 1.00 by the types of scoring. The Cronbach alpha coefficients of the tools were 0.54 and 0.46 by the types of scoring. The average content validity index of the items was 0.95 from 4 pairs of experts. Because there were significant differences between some scores of quality of nursing care of 3 general hospitals regardless of the types of scoring, the tools could be thought to have some construct validity. And also, there were significant correlations between some scores of quality of nursing care and admission days and admission days after surgery regardless of the types of scoring, the tools could be thought to have predictive validity. Conclusion In this study, the evaluation tool of nursing care was developed for the very specified group of patient, G-I surgery patient. And the items were developed and tested by the experts of nursing practice. Because of these reasons, it was supposed that the tool could be used effectively in nursing pratice. And the procedures for the development and the test of the evaluation tool of nursing care in this study were supposed to be used for the developement of other tools.

Patients' evaluation of hospital care is one of the most important aspects of quality assessment. Survey allows patients to judge sujectively the events that occur during their hospital visit if performed properly. This study describes the result of a research effort to develop outpatient questionnaire that has sufficient validity and reliability to be used to measure patients' perception of satisfaction in Korea and to investigate influencing factors on patients' satisfaction. Self-administered questionnaire was developed for outpatient and the survey was conducted covering 827 outpatients in a tertiary hospital. It was confirmed by factor analysis that patients evaluate several components of ambulatory care distinctly ; hospital environment, administration and ancillary services, and medical care. We found strong evidence of construct validity and internal consistency for the above three dimensions of hospital process. On the contrary, reliability of overall outcome measures was low. It suggests that three items concerning overall outcome measures have some different meanings in patients' perception. Using logistic regression analysis it was found that previous health status, cost evaluation, and improvement in health status have significant influences on the level of patients' overall satisfaction and that patient's sex, experience of previous visit, expectation for improvement, cost evaluation, and improvement in health status are strongly related with intention to recommend hospital. In spite of some limitations the results of this study can be used helpfully as baseline informations for developing self-administered questionnaire and for exploring the influencing factors on patients' satisfaction. Further comprehensive research efforts should be made on the measurement of ambulatory patients' satisfaction and its related factors in current Korean situation.

In this paper, we analyzed the misconceptions and errors incurred during factorization learning. We also examined whether online individualization classes had a positive effect on students' mathematical achievement. The experiment was conducted for 4 weeks (16 times in total) on middle school juniors in rural areas of Gyeonggi Province, where the influence of private extra education was small. In the class, the 'Google Classroom' was used as a LMS, the video lecture was uploaded to YouTube, and the teacher interacted with the students through "Zoom" and "Facetalk". In the online class situation, students' assignments and test answers were checked in real time through 'Google Classroom', and immediate feedback was provided to the experimental class group's students. However, for the control group students, feedback was provided only to those who desired. A total of 7 achievement evaluations were conducted in the order of pre-test, formative evaluation (5 times), and post-test to confirm the change in students' ability improvement and achievement. Through the formative evaluation analysis, it was possible to grasp the types of errors and misconceptions that occured during the factorization process. Students' errors were divided into four types: theorem or definition distortion error, functional errors such as calculation, operation, and manipulation, errors that do not verify the solution, and no response. As a result of ANCOVA, the two groups did not show any difference from the 1st to 4th formative assessment. However, the 5th formative assessment and post-test showed statistically significant differences, confirming that online individualization classes contributed to improvemed achievement.

This study was a systematic review and meta-analysis comparing the effects of aquatic exercise and land-based exercise in the treatment of knee osteoarthritis. 7 studies (n=449) met selection and exclusion criteria out of 287 potential studies obtained from the literature search via Ovid-Medline, Cochrane Library CENTRAL, CINAHL, RISS and KISS. The overall risk of bias of selected studies using SIGN (Scottish Intercollegiate Guidelines Network) checklist for randomized controlled trials (RCT) was regarded as low. As a result of meta analysis, Standardized Mean Difference (SMD) for pain was -0.26(95% CI -0.49, -0.03, p=0.03, $I^2=14%$), which implies that aquatic exercise groups had significant less pain than land-based exercise groups. On the other hand, there was no significant difference between aquatic exercise groups and land based exercise groups for flexion Range of Motion (ROM) (-0.12, 95% CI -0.51, 0.27, p=0.53, $I^2=0%$), extension ROM (-0.04, 95% CI -0.55, 0.48, p=0.89, $I^2=43%$), physical function (-0.12, 95% CI -0.44, 0.19, p=0.44, $I^2=0%$), Quality of Life (QOL) (-0.15, 95% CI -0.54, 0.24, p=0.46, $I^2=0%$). This study has some limitations due to few RCTs comparing aquatic exercise groups and land-based exercise groups in the treatment of knee osteoarthritis. Therefore, further RCTs should be conducted along with long-term outcomes.
