PURPOSE: The purpose of this study was to test the validity of a modified clinical performance examination (CPX) for preclinical students in nursing. METHOD: 70 nursing students in their second semester of the junior year at C University participated in CPX. Scenarios and checklists were developed by our research team from September to October 2005. Six stations were organized. Evaluation included physical examination of a patient with lung cancer, education on usage of a metered dosage inhaler, and lobectomy postoperative care. Students were randomly assigned to a station. RESULT: There was a difference in the CPX scores according to stations. The agreement of scoring between trained faculty members and SPs was more than moderate (r=.647). The correlation between the CPX score and the average grade in the previous semester and between the CPX score and the average grade of a paper and pen test of the pulmonary system of adults was low (r=.276; r=.048). CONCLUSION: Traditional CPX is generally recommended, however, modified CPX is appropriate for preclinical students in the current Korean Nursing school setting if there are additional scoring systems to balance the testing level at each station.

A modern development of ambulatory ECG monitoring gave great advances in the diagnosis and evaluation of various cardiac conditions. Fifteen cases of ischemic heart disease, 11 cases of nonischemic heart disease, 5 cases of noncardiac disease and 9 cases of normal healthy subjects were studied from January 1980 to July 1981 in national Medical Center, with the following results: 1) The heart rate was decreased during night time, with less decreasing tendency in patients with ischemic heart disease. 2) Among 30 cases, including 12 patients with ischemic heart disease, who didn't show arrhythmia on routine 12 lead ECG, 12 cases, including 6 patients with ischemic heart disease, showed arrhythmia on Holter monitoring. 3) Among 5 cases with ischemic heart disease who showed premature ventricular contraction on day time monitoring, 2 cases didn't show premature ventricular contraction on nigh time monitoring. 4) The S-T segment and T wave were changed during night time in 2 cases with ischemic heart disease and in 2 normal subjects. From these results, we could assert that Holter monioring or ambulatory ECG tracing would be a good method for diagnosis and evaluation of ischemic heart disease, and other cardiac conditions. Several another studies with this equipment have to be performed and would give more distinctive outcomes.

PURPOSE: The purpose of this study was to investigate the effects of preclinical clinical performance examination (CPX) on nursing students' confidence in their nursing skills and critical thinking competence. METHODS: The design of this research was one-group pretest-posttest, and the participants were 112 nursing students. The preclinical CPX consisted of a clinical examination, patient-nurse relationship, oral test of related knowledge, written test of the nursing process, and debriefing using comprehensive scenarios based on real patient cases. The confidence of nursing skills consisted of an 8-item NRS and the critical thinking competence consisted of a 12-item 4-point scale developed by researchers and measured in both the pretest and posttest. The collected data were analyzed using paired t-tests, ANOVA, and Pearson correlation coefficients. RESULTS: The score for confidence in nursing skills (t=10.60, p<.001) and that for critical thinking competence (t=7.03, p<.001) increased significantly after preclinical CPX. CONCLUSION: This study showed that preclinical CPX was effective in improving nursing students' confidence in their nursing skills and critical thinking competence. Therefore, preclinical CPX is expected to be utilized in nursing practice education. Additional studies including those on control groups are recommended to compare differences between the preclinical CPX group and control group.

BACKGROUND: After the World-Wide-Web(www) appeared, history has abruptly fallen in the new era of the Internet. In Korea, after the first medical internet site appeared, there was a major development in the WWW. But the quality and quantity of the web-page remains in infancy. Therefore, through the analysis of the Korean medical internet sites on present status, directions for development of Korean medical internet sites can be made. METHODS: From April 1st, 1999 to June 30th, 1999 in the Korean web sites, we visited 1044 sites. They included "Medmark Korea" representing medical search engine, "Eulji medical library" in the Eulji Medical College Hospital, and the medical sites of the "Yahoo Korea", "naver.com", and "simmani.com". Through this internet search, the information about locations, first publication year, classification by characteristics of homepage, speciality, web service form was obtained. Among these sites, acquireing from insufficient source further, questions were sent to the webmasters of 143 websites by e-mail. The questions included 7 items on the characteristic of webmasters, 8 items on the general characteristics of internet sites, 8 items on the contents, and their own comments. RESULTS: The occupation of webmasters was as follows: were physicians 94.4%, were male. According to age distribution, those in their thirties was 48.2%, and forties, 33.3%. Amone the 521 websites confirmed, there were 44 sites in 199 151 in 1996, 237 in 1997, and 79 in 1999. According to the distribution of location, metropolitan areas including Seoul, Inchon, Kyonggi occupied 68.9% among total. The main portion of the intentional visitors was ordinary people comprising 39.2%, members 9.8%, and physicians 7.7%. Concerning the purposes of publication, 38.7% of websites intended for health education to citizens, 31.0% for publicity of hospital or organizations, and 15.5% for exchange of information between members. For the most significant contents, 26.6% focused on the common-sense health issues, 35.7% on exchange of special medical information, 8.4% on education data for medical students, and 13.3% on publicity of hospitals. For the update interval, 22.0% renewed their sites within 1 week, 22.7% in 1 month, 23.4% in 3 months, and 20.6% in 6 months. For the effectiveness of homepage, the rate of `good' and `very good' response was 52.8%. CONCLUSION: Our investigation, showed that medical internet sites are lead by those in their thirties and forties. Web sites was concentrated to metropolitan areas where informational infrastructure was well developed. It is emphasized that efforts to informationalization by are needed by, governmental medical database systems should be established, and that the guidelines which enables validity of medical information should be set forth.

Background/Aims: We explored whether high sodium intake, assessed by urinary excretion, determines the risk of sarcopenia and nonalcoholic fatty liver disease (NAFLD). Methods: We analyzed 10,036 adult participants with normal kidney function from the Korea National Health and Nutrition Examination Survey (2008–2011). NAFLD was identified using the fatty liver index, and the muscle mass was evaluated using dual X-ray absorptiometry. The dietary sodium intake was estimated using Tanaka’s equation. Results: The mean 24-hour urinary sodium excretion was 144.2±36.1 mmol/day (corresponding to 3.3 g/day Na) in the total population. The 24-hour urinary sodium excretion showed moderate accuracy in predicting NAFLD (area under the receiver operating characteristic, 0.702; 95% confidence interval [CI], 0.692 to 0.712). A cutoff value of 99.96 mmol/day (corresponding to 2.30 g/day Na) for urinary sodium excretion in predicting NAFLD showed 76.1% sensitivity and 56.1% specificity. The results of multiple adjusted models indicated that the participants with the highest urinary sodium excretion had a significantly higher risk of NAFLD (odds ratio, 1.46; 95% CI, 1.27 to 1.66; p<0.001) and sarcopenia (odds ratio, 1.49; 95% CI, 1.28 to 1.73; p<0.001) than those with the lowest urinary sodium excretion. The association between a higher 24-hour urinary sodium excretion and NAFLD was independent of sarcopenia. Conclusions Participants with a high sodium intake, as assessed by sodium excretion, had a substantial risk of NAFLD and sarcopenia

The purpose of this study was to identify the effect of social support revealed in the time duration of sick role behavior compliance on the patients with hypertension using Quasi- experimental research design. Data collection was made through the interview survey technique from the hypertensive patients who received social support intervention (experimental group, n=41) and from those who were not exposed to the intervention(control group, n= 34). The subjects were registered in the cardiovascular outpatient clinic at the Chonnam National University Hospital from June 3, 1996 to November 30, 1997. X2-test or t- test, Repeated measures ANOVA were utilized in the data analysis. The results were as follows: 1. The effect of social support intervention on sick role behavior compliance was significant in 1 month(F=69.17, p=.000), 6 months (F=11.51, p=.001), and 12 months(F=.07, p=.789) and between two groups(1 month; F=153.70, p=.000, 6 months; F=13.94, p=.000, 12 months; F=6.72, p= .011). 2. The effect of social support intervention on blood pressure was not significant through all the periods of time (F=1.21, p=.274) between the two groups(F=.12, p=.732). In conclusion, it was showed that social support had an effect on sick role behavior compliance and the effect of social support continued for twelve months(F= 10.03, p=.002) However, the score of compliance tends to decrease after 6 months of intervention. Therefore, this study indicated that social support re-intervention would be needed between six and twelve months.

Effects of root, stem and leaf extract of sancho (Zanthoxylum schinifolium) on the inhibition of lipid peroxidation in the hepatic microsome of rat, DPPH radical scavenging activity and activated partial thromboplastin times (APTT) were examined in vitro. The highest inhibition of hepatic microsomal lipid peroxidation was observed by ethyl acetate fraction than that of methylene chloride fraction of the root and stem extracts. The high inhibition of lipid peroxidation was determined in the leaf, the root and the stem in order. The DPPH radical scavenging activity of ethyl acetate fraction was higher than that of n-butanol fraction and it was similar to the root and the steam extract. It was similar to the inhibition of hepatic microsomal lipid peroxidation. The DPPH radical scavenging activity was the highest in 2.500 mg/mL of ethyl acetate fraction and it was 4.4 fold higher than that of h-tocopherol, as an antioxidant standard. The DPPH radical scavenging activity was dependent on the extract concentration in the range of 0.125 - 5.000 mg/mL. The thromboplastin times were higher than that of n-butanol fraction and it was similar to the root and the steam extracts. The leaf extract showed the highest antithrombogenic effect followed by the stem and then the root extract. The activated partial thromboplastin times were dependent on the extract concentration in the range of 0.100 - 2.000 mg/mL. Consequently, the effects of antioxidative, DPPH radical scavenging activity and antithrombogenic of Z. schinifolium was observed due to the inhibition of lipid peroxidation and the DPPH radical scavenging activity by methylene chloride, n-butanol and ethyl acetate fraction of the leaf extract.

OBJECTIVE: To evaluate the effectiveness of the modified constraint-induced movement therapy (CIMT) for inpatient rehabilitation of the stroke patients. METHOD: Twenty-four patients admitted by subacute or chronic stroke were enrolled and divided into two groups, experimental and control groups. The experimental group (n=13) received the CIMT five days a week for 2 weeks. Less affected arm was restrained for 14 hours a day, practicing purposeful activities with more affected arm for 6 hours a day in group setting. The control group (n=11) received conventional occupational therapy for the same period. The outcome was measured by Fugl-Meyer MotorAssessment (FMA), Brunnstrom stage, Jebsen hand function test, grip strength, Box and Block test, nine hole peg test, Functional Independence Measure (FIM), and Motor Activity Log (MAL). RESULTS: The experimental group showed significantly higher improvements (p<0.05) in FMA, Brunnstorm stage, Jebsen hand function test, grip strength, Box and Block test, FIM, and MAL. CONCLUSION: Modified CIMT delivered in group setting is considered to be an effective treatment to improve functional use of the hemiparetic arm of stroke patients in inpatient setting.

The aim of this study was to develop and evaluate a web-based learning program with multimedia ECG monitoring for clinical nurses. For this, we compared the self-directed, web-based learning method with the traditional lecture method. A quasiexperimental, nonequivalent control group pretest-posttest design was used, the data from 32 nurses(17 for experimental group and 15 for control group) were collected from October 1 to November 30, 2001, and analysed by SPSS program with x2 test, ttest, ANCOVA. The results were as follows : 1) There was significant improvement in the score on learning achievement of the experimental group compared with that of the control group(t=-2.739, p=.010). 2) There was no significant difference between the groups in learning motivation(t=-.054, p=.4785). In conclusion, it is suggested that a higher learning achievement was achieved in self-directed, web-based learning than in the traditional classroom style learning. There was also evidence that two educational styles had same effect in creating motivation. We propose to utilize a self-directed, web-based leaning method as a means to continue life-long education for nurses on a rotational duty system.
