The present study evaluated of regeneration effect of platelet rich plasma on the treatment of grade II furcation involvement, with coralline calcium phosphate bone in humans. 30 teeth with grade II furcation defect were selected and 15 teeth(control) were treated with coralline calcium phosphate bone, the others(test) were treated with coralline calcium phosphate bone and platelet rich plasma. Pocket depth, clinical attachment level, width of keratinized gingiva width were measured at baseline, postoperative 3, 6months. from cementoenamel junction to alveolar crest and fundus were measured at baseline, 6months(re-entry). Both groups were statistically analyzed by Wilcoxon signed Ranks Test & Mann-whitney Test using SPSS program(5% significance level). The results were as follows: 1. Pocket depth, clinical attachment level, keratinized gingva width, cementoenamel junction - alveolar crest, cementoenamel junction - fundus were not differ significantly in both groups at baseline 2. The change of pocket depth, clinical attachment level, keratinized gingva width, cementoenamel junction - alveolar crest, cementoenamel junction - fundus in both groups were decreased significantly at 3, 6months(p<0.05). 3. The change of pocket depth, clinical attachment level in test group decreased significantly than control at 3, 6months(p<0.05). 4. The change of keratinized gingiva width, cementoenamel junctional - alveolar crest, cementoenamel junction - fundus were not differ significantly in both groups at 3, 6months. 5. The pocket depth, clinical attachment level, keratinized gingiva width exhibited marked changes at 3 months in both groups. In conclusion, the results of this study suggest that platelet rich plasma have adjunctive clinical treatment effect to periodontal regeneration in grade II furcation defects.

This study aimed to understand the factors having effects on the satisfaction with clinical practice of nursing students. For the data collection, this study conducted a survey utilizing the questionnaire targeting 188 students(third & fourth year) of two nursing colleges located in a province, from September 1st to September 30th 2019. Using the SPSS WIN 21.0 Program for the data analysis, this study used the t-test, ANOVA, Scheffe test, Pearson correlation coefficient, and multiple regression analysis. In the results of this study, the satisfaction with clinical practice of nursing students had positive correlation with subjective happiness, and negative correlation with perceived stress. The factors having effects on the satisfaction with clinical practice were major satisfaction, gender, perceived stress, subjective happiness, and subjective health status, and the explanatory power of those variables was 21.9%. Based on such results of this study, it would be necessary to develop the complex educational programs considering the elements like decrease of perceived stress and improvement of subjective happiness at the same time, in order to improve the satisfaction with clinical practice.

Purpose: To identify the effects of clinical practicum reinforcement program on nursing student's clinical competency and satisfaction in the ICU. Methods: The study utilized a quasi-experimental pretest-posttest research design. The participant was 76 senior nursing students, who were engaged in two week-long clinical practicum in ICU at the C university hospital in a G city, Korea. The clinical practicum reinforcement program was applied to the experimental group (n=39), while the control group (n=37) was involved in the conventional practicum program. The collected data were analyzed using descriptive analysis, $x^2$/Fisher's exact test, and t-test, ANCOVA with SPSS/WIN 18.0 program. Results: After 2 weeks' clinical practicum, the experimental group showed a statistically significant increase in the clinical performance abilities by self evaluation, when compared to the control group. Clinical instructor's evaluation on the student's clinical performance revealed that the experimental group showed higher level in nursing activity than that of the control group (p<.001). However, there was no significant difference between the two groups in terms of the satisfaction on the clinical practicum program except the learning guidance and the evaluation. Conclusion: The clinical practicum reinforcement program is an effective one for improving the student's clinical competency.

Polysomnography is used to diagnose many types of sleep disorders including sleep apnea, periodic limb movement disorder, REM sleep behavior disorder, parasomnias, and narcolepsy. It is a comprehensive recording of the biophysiological changes that occur during sleep. The polysomnography monitors many body functions parameters including EEG, EOG, EMG, ECG, respiratory airflow, respiratory effort, and pulse oximetry during sleep. Multiple Sleep Latency Test (MSLT) is performed for diagnosing narcolepsy and excessive daytime sleepiness. It is usually to be done after an overnight polysomnography. The test consists of four or five 20-minute nap opportunities that are scheduled two hours apart.

PURPOSE: The Fukuda test can be used at home and in school to diagnose scoliosis at an early stage and prevent serious curvature of the spine. This study aimed to use the Fukuda test to detect scoliosis. An additional aim was to invoke the national interest in imbalanced postures and habits, which result in scoliosis, by providing data obtained in periodic assessments. METHODS: The study consisted of 35 idiopathic scoliosis patients (22 in right lumbar spinal region and 13 in the left lumbar spinal region). The distance of displacement and angle of displacement were measured following the Fukuda test. A correlation analysis was then used to examine the distance of displacement and angles of displacement and rotation with regard to the direction of the curve in scoliosis. RESULTS: There was a significant negative correlation (p<0.00) between the direction of the curve in scoliosis and the angle of displacement, but there was no correlation between the cobb's angle and distance of displacement or between the cobb's angle and angle of rotation. CONCLUSION: The Fukuda test did not capture changes in spinal curvature such as the cobb's angle, or subsequent changes in the muscles. Thus, the Fukuda test is not suited to examining the direction or status of the thoracic curve in scoliosis patients. Simple methods to objectively measure scoliosis need to be developed.

The most common sources of biological trace material which are found in crime scene are the human bloodstains. Reliable identification in the forensic casework is important as it provides crucial insights into crime scene reconstruction and can thus contribute towards solving crimes. Blood-stains are routinely tested in forensic practise using various methods including the leucomalachite green (LMG) test, Kastle-Meyer phenolphthalein test, tetramethylbenzidine test, orthotolidine test, or the luminol chemoluminescence test with the latter cleaning attempts. All these presumptive thus indicative but not identifying tests take advantage of the peroxidase-like activity of the heme unit of the hemoglobin molecule in human blood. Therefore, false-positive results can be caused by the presence of strong oxidants, such as chlorine-containing detergents or by true peroxidases (e.g., from plants). In this study, composition for Gum guaiac was evaluated for the forensic identification of bloodstain and compared with the LMG. The sensitivity and specificity of the composition for Gum guaiac were examined more stable in bloodstain. The positive of Composition for Gum guaiac shown even with the 100,000-fold diluted bloodstain, which was no difference in comparison with LMG test. It was shown that composition for Gum guaiac was very stable to resist boiling for 20 minutes and the effect of bacteria did not affect the genetic analysis as well. The above result of the crime scene investigation, composition for Gum guaiac is easily expected to help identifying bloodstain in the evidences.

Carotid Intima-Media Thickness (CIMT) testing is a test that precisely assesses cerebrovascular and coronary heart diseases. According to many previous studies, CIMT predicts atherosclerosis and is highly correlated to cardiovascular disease risk factors. It has also been reported that CIMT is an independent predictor of risk factors for myocardial infarction and stroke. Therefore, the purpose of this study is to investigate CIMT and other independent factors through a correlation study with the clinical laboratory test results of a blood test. As a result, this study could not prove the correlation between CIMT and risk factors of cardiovascular disease (TC, TG, LDL cholesterol, and HDL cholesterol) due to an insufficient number of subjects. Nevertheless, a positive correlation was demonstrated between CIMT and ALT (p<0.05), GGT (p<0.05), Uric acid (p<0.05), and CEA (p<0.05) at a statistically significant level, suggesting a continuation of the study.
