본 논문은 적시학습을 위한 집단지성 기반 오답노트 시스템의 필요성과 개념을 제시하고 활용도 및 만족도를 보인다. 기존 오답노트 시스템은 평가문항에 대한 정답 여부를 체크하여 응답 결과가 오답인 문항에 대하여 일괄적인 정답 해설을 제공하는 특징을 갖고 있다. 이러한 특징은 학습자가 평가문항을 잘 이해하지 못하고 운 좋게 맞은 문항과 개별 학습자들의 오답 선택 과정에 대한 오류를 적절하게 피드백 받지 못하기 때문에 오답분석과 피드백 측면에서 많은 개선을 필요로 하고 있다. 본 논문에서는 이러한 '점수의 오류'를 개선하여 학습자의 취약점을 보완하는 새로운 방법인 SERO(Stability Emergency Risk Opportunity) 오답노트를 제안한다. SERO 오답노트는 자신이 풀어낸 평가문항들을 4가지 유형(S유형, E유형, R유형, O유형)으로 분류하고, 정답 해설 뿐만 아니라 집단지성을 이용한 다양한 오답노트 해설들을 제시하여 학습의 만족도를 높인다.

The purposes of this study were to develop the standard indicators to evaluate the food and nutrition systems in hospitals and to test the validity of those items scientifically. The results were as follows: First, the conceptual validity was examined with recognition degrees of importance from the hospital nutrition department managers. All of the hospital nutrition department's operation evaluation standards and the indicators' conceptual validity tested were in the range of 3.71~4.93 out of 5.0, and the mean score was 4.36. Therefore, the conceptual validity was verified. Second, to verify the factor validity of the items of the standards and indicators for the hospital nutrition department's operation evaluation, the standards and indicators were analyzed as key-factors. Key-factor analysis after vertical rotation showed that four factors appeared and were composed of (a) facilities management, (b) sanitation management, (c) operation & foodservice management, and (d) nutrition management. Third, the reliability of the standards and indicators for the hospital nutrition department's operation evaluation was analyzed and resulted in a score of 0.98, which showed good internal consistency. Fourth, the discriminative power of each item of the standards for the hospital nutrition department's operation evaluation was tested by checking the differences between groups with first quartile and forth quartile of total evaluation scores. The indicators having low distinction power were modified into obligatory items or eliminated for better differentiation.

Background : Eight-Constitution Medicine (ECM) devides the human body into eight constitutions. Up until now, checking the pulse types is only way to classify the eight constitution. Recently we try to make a questionnaire that is based on the Eight-Constitution characters and analyze the answer from patients who were classified into one of the eight constitutions according to their pulse types and their responses to constitution-acupuncture therapy. Objective : This study intends to analyze each answer of the Eight-Constitution Questionnaire with independent sample t-test. Methods : Participants of this study were outpatients in ECM clinics located in Korea. The resources were collected from 925 patients who were classified into one of the eight constitutions according to their pulse types and their responses to constitution-acupuncture therapy. SPSS 13.0 for Windows was used for independent sample t-test. Results and Conclusions : 1. The proportion of participants' constitutions is in the order of Pancreotonia (28.0%), Colonotonia (17.3%), Pulmotonia (18.1%), Hepatonia (18.1%), Vesicotonia (8.5%), Cholecystotonia (7.0%), Renotonia (2.6%) and Gastrotonia (0.4%). 2. Eight-Constitution Questionnaire consists of 5 parts; Appearance, Character, Body reaction, Physiology & Pathology and Food reaction. 3. 18 items were chosen among 81 question about Character. 4. Due to the deficiency of Gastrotonia examples, useful items have to be given up. If we can gather Gastrotonia examples, we can use meaningful items more than 18.

Purpose: This methodological study translated, adapted, and validated the evidence based guideline of RNAO (Registered Nurses Association of Ontario) in Canada, for acute stroke care to domestic circumstances. Methods: Quality of the RNAO guideline was evaluated using AGREE tool. Then the guideline was translated into Korean and a preliminary guideline was established After checking content validation by an expert group, the Korean version of the guideline was applied to clinical settings to see its applicability. Results: The RNAO guideline in Korea was deemed appropriate. The Korean version of the guideline was drawn up with 56 items in 3 areas in stroke system related nursing, nursing of acute stroke inpatients, and stroke nursing assessment. A questionnaire survey was performed on appropriateness, enforceability, and applicability of those recommendations. A total of 54 recommendations were finalized after deleting 2 items below CVI 0.7 and correcting 3 items by taking professional advices. After trial application of the guideline to 40 stroke patients hospitalized at a ward of a hospital in Seoul, its performance was improved but was not statistically significant. Conclusion: This guideline is expected to contribute to improving nursing quality by offering it as a guide to evidence based practices for acute stroke care in Korea.

Purpose: The objective of the present study was to develop and evaluate a legal communicable diseases (LCDs) electronic system for infection control. Method: The system was developed through the procedure of analysis, design, implementation, application and evaluation, and was applied within an OCS (order communication system). Results: As indicated by the main menu, the present system is composed of an improved perception system for enhancing perception of LCDs, LCDs identification system, and improved efficiency in the report system. Detailed items included in the main menu are introduction and log-in screen, pop-up window for checking the outbreaks of LCDs, decision making icon, electronic signature icon, electronic report form, email system, etc. The total number of reports was greater after the application of the system (n=99) than before (n=80), and the adequacy of report time was statistically significantly higher after application of the system (P<0.05) Conclusion: The present system suggests a new method for LCDs report and infection control, and is expected to be adopted by other medical institutions in the future.

The purpose of this study was to investigate the impacts of managerial behaviors on the satisfaction with management. The data were collected by means of questionnaire distributed to a stratified sample of 560 housewives in Seoul. The questionnaire consisted of 107 items was developed by the researchers. Frequency, percentile, mean, and stepwise multiple regression were used to analyze the data. The results of stepwise multiple regression analyses indicate that the wives who had more reality in planning and higher standards tended to more satisfy with managerial behaviors. The elements of inplementing such as facilitating conditions and checking behaviors were positively related with managerial satisfaction. The recommendations for the ways to increase satisfaction with management and future research were suggested.

The purpose of this study is to explain the importance of Vibration Monitoring Device by introducing an example of Predictive Maintenance System using Condition Monitoring System of Hydro-turbine generator. Confirming vibration of generation equipment is commissioning procedure during equipment completion for checking guaranteed items. Data from Generator output range are used to determine output band to continue the performance of equipment. The Vibration Monitoring System is not absolute method of maintenance, but if it is used well with expert, it will be visible, data-analyzed, scientific maintenance more than others. And also, Condition Monitoring System is very important for remote controlled small hydro-power plant although most of it is installed in Large hydro-power plant.

Background: Although school footpaths must guarantee pedestrians’ safety and pleasantness, even facilities installed according to standards provided in “Rules on the Designation and Management of School Zones” are not maintained and managed properly and as a result they are not effective for securing the safety of school footpaths. Purpose: The present study surveyed the physical environment of elementary school footpaths and investigated problems posed by the absence of facilities. Methods: First, the current state of street structure was investigated using maps as well as field surveys, and the current state of street furniture was surveyed by checking if it has been installed and photographing it. In addition, traffic characteristics were investigated by measuring traffic safety while children’s going to school and home, and children’s behaviors on school footpaths were surveyed by observing their behaviors when going to school and home. Result: This study surveyed the installation and state of safety facilities on school footpaths around elementary schools in B City, analyzed items to be improved, and presented materials for reducing accidents among elementary students.
