For this purpose, the authors proposed and proved usefulness of the modified mean skin temperature which is integrated mean radiation temperature and the effect of floor contacted heat conduction. The mean radiation temperature is applied form factor between half cross-legged human body and surrounding wall of indoor. In addition the floor contacted heat conduction is applied heat transfer coefficient of half cross-legged human body. Eight Korean young men were targeted for the experiment. From the experiment the authors excerpted physiological reaction and psychological reaction in Ondol environment which is combined physiccal environmental factor of artificial climate chamber, air and floor temperature. As a result of the experiment it is confirmed that heat conduction has more impact than heat exchange from existing research for the heat exchange between half cross-legged human body and surrounding wall in Ondol thermal environment. Thereby, it is proved the effectiveness of the modified mean skin temperature which is added floor contacted temperature to the Ondol thermal environmental evaluation index.

This study was carried out to evaluate the usefulness and the effectiveness of the nutrition education website 'ifood(http://ifood.or.kr)', for children. A total of 262 children (5th and 6th graders) participated in the self-education program using the website which consisted of 4 sessions every two weeks. In each session, they were asked to answer some questions on the comprehensiveness of each topic while navigating the website. Nutrition knowledge (20 items), dietary attitudes (7 items), and dietary behaviors (10 items) were evaluated using questionnaires before and after the education. After the education, the usefulness and readability of the website was also evaluated. Most (97.2%) of the responders reported that the education using this website was helpful, 97.3% thought that the contents were reliable, 90.1% responded that the contents were easy to understand, and 88.8% answered that they would revisit 'ifood'. The menus they liked best were 'Interesting games' for 35.8%, 'How can I cook?' for 17.8%, 'How can I become slim' for 16.4%. This website might be more attractive by providing a 'greater variety of contents in detail', 'more music, motion pictures and images', 'more interesting games'. After the education, there was a significant increase in nutrition knowledge scores from 10.9 to 13.1. Although the total scores of dietary attitudes and dietary behaviors did not improve, there was a significant increase in each of some questions. These results showed that 'ifood', a nutritional education website, was desirable in reliability, aesthetics and enjoyability, and was effective in improving nutrition knowledge and some of dietary attitudes and behaviors in children.

Purpose: Many patients are injured by trauma. And some of them expire due to severity of trauma. Various scoring systems have been introduced in grading severity and predicting mortality of trauma patients. This study is to evaluation the usefulness of factors for determining the severity and predicting the prognosis of the trauma victims. Methods: Data on the patients who visited our Emergency departments from January 2010 to December 2011 were retrospectively reviewed using electronic medical records. The patients were activated severe trauma team calling system. The patients were categorized as survivors and non-survivors. Univariated associations were calculated, and a multiple logistic regression analysis was used to determine variables associated with hospital mortality. Results: Two hundred sixty two(262) patients were enrolled, and the mortality rate was 25.6%. By multivariate analysis, lower respiration rate, lower Glasgow Coma Score, higher International Normalized Ratio and emergency transfusion within 6 hours were expected as severity and prognosis predict factors (each of odds ratio were 24.907, 14.282, 2.667 and 16.144). Conclusion: As predict factors, respiration rate, Glasgow Coma Score, International Normalized Ratio and emergency transfusion, are useful determining the severity and predicting prognosis of trauma victims.

Objectives: This study was performed to examined the effectiveness evaluation of peer education program on smoking prevention and cessation for elementary school students. Methods: Data were collected from 60 students in a rural area through self-administrated questionnaires. Child-leaders participated the peer education program to assist their friend, parent, and adult in community to quit the smoking for 4 weeks. Results and Conclusions: Major conclusions were as follows : 1. The peer education program on smoking prevention and cessation for elementary school students was reinforce to increasing the tobacco knowledge and the cessation skill, learning the communication skill, and improving the empowerment. 2. Image of tobacco, intention of smoking in future, recommendation for smoking cessation, pro of smoking. con of smoking, and level of assert in post-test were higher than those in pre-test. 3. There were significant differences in image of tobacco, con of smoking, and level of assert by grade between the pre-test and the post-test of peer education program. But intention of smoking in future, recommendation for smoking cessation, and pro of smoking were not related to effectiveness of peer education program. 4. Child-leaders for smoking prevention and cessation performed the their task to 1.4 persons per student. 5. Participating students were satisfied with the contents of program, the usefulness of educational materials, and preference of parents, but they were not satisfied with the usefulness of task note, learning time, and lecture room.

The purpose of this study was to investigate the relationship between media richness, media usefulness, media experience and media decision in order to identify factors that determine the media of school library in solving performance evaluation tasks. For this purpose, 132 primary and middle school students were surveyed and their structural equation was set up by hypothesis setting, validity test, and causal model. As a result, it was confirmed that media experience of school library is a major factor in media decision. Also, media richness and media experience appeared to influence media decision through media usefulness. The analysis implies that school library is centered on teaching - learning process and evaluation, so information literacy education should be carried out in school curriculum and school library is required to provide students experience on media as the center of school education.

The tools that classify the severity of patients based on the prediction of mortality include APACHE, SAPS, and MPM. Theses tools rely crucially on the evaluation of patients' general clinical status on the first date of their admission to ICU. Nursing activities are one of the most crucial factors influencing on the quality of treatment that patients receive and one of the contributing factors for their prognosis and safety. The purpose of this study was to identify the goodness-of-fit of CPSCS of critical patient severity classification system(CPSCS) and Glasgow coma scale(GCS) and the clinical usefulness of its death rate prediction. Data were collected from the medical records of 187 neurological patients who were admitted to the ICU of C University Hospital. The data were analyzed through $x^2$ test, t-test, Mann-Whitney, Kruskal-Wallis, goodness-of-fit test, and ROC curve. In accordance with patients' general and clinical characteristics, patient mortality turned out to be statistically different depending on ICU stay, endotracheal intubation, central venous catheter, and severity by CPSCS. Homer-Lemeshow goodness-of-fit tests were CPSCS and GCS and the results of the discrimination test using the ROC curve were $CPSCS_0$, .734, $GCS_0$,.583, $CPSCS_{24}$,.734, $GCS_{24}$, .612, $CPSCS_{48}$,.591, $GCS_{48}$,.646, $CPSCS_{72}$,.622, and $GCS_{72}$,.623. Logistic regression analysis showed that each point on the CPSCS score signifies1.034 higher likelihood of dying. Applied to neurologically ill patients, early CPSCS scores can be regarded as a useful tool.

Purpose: The aim of this study was to testify whether clinical performance examination (CPX) was useful to evaluate comprehensive performance for nursing students just prior to graduation. Method: A cross-sectional descriptive study was designed to examine the usefulness. A total of 61 nursing students whose requirement credits were completed for graduation from a C University in G-city, at December, 5, 2007. Data were analyzed by Pearson's Correlation Coefficient and Spearman's rank Correlation Coefficient. Results: This study showed that both of the finals scores with paper and pens and the clinical practicum scores were not correlated with the CPX scores (r=-.031, p=.811; r=.028, p=.831). Consistency of scores between faculties and standardized patients was moderate (r=.752, p=.000). Conclusion: CPX was considered as a different and innovative evaluation from previous testing systems to test the various aspects of performance including knowledge, skill and attitude. Therefore, CPX under high raters' consistency was useful to test nursing students's final performance. Further study would be needed to develop the standard of CPX system.

The prognosis of maintenance hemodialysis (HD) patients is closely related to their nutritional status. It is important to develop and use of a reliable, useful and easy method of nutritional assessment scale for evaluation of nutritional status and progression of the patients. This study was initiated to evaluate the clinical usefulness of Instant Nutritional Assessment Scale(INAS) by cross-sectional and longitudinal studies. One hundred HD patients entered a continuing nutritional study and followed for 1 year. The results were as follow ; 1. 24% of patients was normal to mild, 43% was moderate and 33% was severe deficit of nutritional status. 2. The mean INAS score of the patients was 8.00(S. D.=2.83), and there didn't reveal any differences in INAS score by general characteristics. The mean transferrin score was 1.98, whih was the highest of 5 nutirtional parameters of INAS. Only 7 patients had within nomal range of transferrin concentration. 3. Within one year since this study was initiated, 10 patients died. Six of them were with severe deficit and one of them was normal to mild deficit groups. The death rate in severe deficit group was higher than that of normal to mild deficit group (P=.0640). 4. Occurrence of acute complication during HD in severe deficit guoup was higher than that of normal to mild deficit group(P=.001). 5. The number of consultation to the doctor and hospital admission in severe deficit group was higher than that of normal to mild deficit group(P=.0001). 6. INAS score was significantly correlated with occurrence of acute complications during HD and the number of consultation to the doctor. In conclusion, INAS based on the levels of body mass index, midarm circumference, triceps skinfold thickness, transferrin concentration and total lymphocyte count seems to be a reliable predictive nutritional index for prognosis. So nurses are encouraged to adopt INAS in care of the chronically illed patients. Recommendations for further research was suggested.
