  • Objectives : The purpose of this study is to introduce and examine the possibilities of infrared (IR) imaging, biophoton detection and gas discharge visualization(GDV) as diagnostic tools in Korean Medicine. Methods : To review the basic mechanism and measurement methods of three modalities, concepts in physics were introduced. Physical backgrounds of IR, biophoton and GDV were briefly explained based on recent research papers. Simple electronics was employed for relevant detectors. In order to find the relation between Korean Medicine and these methods, papers on their applications were reviewed. Opinions from the experts on each modality were obtained from their papers and private communications. Results and Conclusions : IR imaging has been used as an auxiliary diagnostic tool but there are some rooms for the improvement for clinical applications. Experimental confirmation of the meridian activation by a moxa cigar is necessary for its verification. Biophoton is not correlated with human skin temperature but it has a circadian rhythm. Biophoton and GDV have a negligible relation if any. Therefore there are no correlations among three modalities in terms of basic mechanisms. But their clinical relations are yet to be scrutinized. Biophoton and GDV need more rigorous clinical tests before they can be used as diagnostic tools.

  • Purpose: The purpose of this study was to compare professional self-concept, clinical nursing competence, and practicum satisfaction between nursing students with and without pediatric nursing clinical preceptorship. Methods: This study used a comparative research design. A total of 85 junior nursing students participated in the study, and data from 76 students were analyzed using SPSS WIN 20.0. Among them, 44 students experienced pediatric nursing clinical preceptorship. Results: The students with clinical preceptorship showed a significantly higher score in nursing skill related items of professional self-concept and the confidence in knowledge of injection preparation and administration compared to the counterpart students. Practicum satisfaction was also significantly higher in the students with clinical preceptorship than in the other students. There were significant positive correlations among professional self-concept, performance confidence, and practicum satisfaction. Conclusion: The study findings suggest that clinical preceptorship is an effective educational method to teach clinical practicum of pediatric nursing. The use of clinical preceptorship needs to be considered to motivate nursing students actively involved into the clinical practicum. The roles of clinical preceptors should be clearly identified in clinical education.

  • Purpose: A network meta-analysis was conducted to assess the comparative effects and ranks of repositioning for pressure ulcer prevention in adults. Methods: A network meta-analysis was performed in a frequency method, using the "netmeta" package of R software version 4.1. The effects of repositioning intervention were confirmed by the odds ratio. The comparative ranking of the repositioning effects was confirmed using the cumulative probability (P-score). Results: Seven intervention studies were included in this study. Based on the P-score, the use of the repositioning system was ranked as the most effective among all interventions (P-score 78.7%). Next was 3~4-hour repositioning combined with memory foam mattress use (P-score 77.2%), use of wearable sensor (P-Score 61.4%), 2-hour repositioning combined with memory foam mattress use (P-score 59.1%), 2-hour repositioning combined with powered air pressure redistribution mattress use (P-score 18.0%), and 4-hour repositioning combined with powered air pressure redistribution mattress use (P-score 18.0%). Conclusion: This study provides information on the relative comparative value of various repositioning interventions to prevent pressure ulcers using network meta-analysis. This is expected to be useful for nurses' decision-making when applying repositioning interventions in clinical practice

  • Purpose: The purpose of this study was to explore preceptees' experience among nursing students in the Clinical Nursing Practice program as integral practice. Specific aims were to identify problems students face as preceptees at a clinical practice and how they interact with preceptors and others. Methods: Grounded theory methodology was utilized. Data were collected from interactive field notes and transcribed notes with individual in-depth interview from 12 senior nursing students who had experiences as a preceptee in the Clinical Nursing Practice. Results: Through constant comparative analysis, a core category emerged as "Being refined while taking a firm stand with lack." The process of "Being refined while taking a firm stand with lack" consisted of four phases: sailing phase, adaptation phase, achievement phase and wistful returning phase. Conclusion: The findings of the study indicate that there is a need for nursing students to understand the limitations and strengths to learning experiences in preceptorship. In addition, the Clinical Nursing Practice as an integral practice program is needed to improve nursing capacity and for proper adaptation to real clinical environment among graduating students.

  • Objective: First-in-human dose estimation is an essential approach for successful clinical trials for drug development. In this study, we systematically compared first-in-human dose and human pharmacokinetic parameter estimation approaches. Methods: First-in-human dose estimation approaches divided into similar drug comparison approaches, regulatory guidance based approaches, and pharmacokinetic based approaches. Human clearance, volume of distribution and bioavailability were classified for human pharmacokinetic parameter estimation approaches. Results: Similar drug comparison approaches is simple and appropriate me-too drug. Regulatory guidance based approaches is recommended from US Food and Drug Administration (FDA) and European Medicines Agency (EMA) regarding no-observed-adverse-effect level (NOAEL) or minimum anticipated biological effect level (MABEL). Pharmacokinetic based approaches are 8 approaches for human clearance estimation, 5 approaches for human volume of distribution, and 4 approaches for human bioavailability. Conclusion: This study introduced and compared all methods for first-in-human dose estimation. It would be useful practically to estimate first-in-human dose for drug development.

  • Purpose: The purpose of this study was to provide basic data to establish effective clinical training programs by identifying various factors that influence the satisfaction of physical therapy students with those programs. Methods: The study subjects were 205 students from six colleges (two 4-year and four 3-year colleges) who participated in clinical training programs. The colleges have physical therapy departments and are located in Busan, Ulsan, and Gyeognam. A survey consisting of 75 questions was conducted between March and December, 2003. Survey responses were analyzed through a frequency analysis, descriptive statistics, and the multiple responses approach, and correlations among the questions were analyzed using a chi-square test. Results: The level of satisfaction with clinical training programs did not differ according to the school system or the size of the clinical training institution. However, several factors led to a higher level of satisfaction, including more active participation of students in the clinical training, more intensive instruction from school professors, a larger number of subjects to complete before the clinical training, and a higher level of student perception that their institution's clinical training program was systematic Conclusion: This study surveyed physical therapy students located in Busan, Ulsan, and Gyeongnam who attended selected schools and training institutions that have their own individual characteristics; therefore, this study may have limitations for comparative analysis. However, if more extensive studies are per formed regionally in the future using the approach taken here, clinical training programs could be developed that can satisfy both schools and the industry.

  • Objective : To observe the trend in clinical study on atopic dermatitis(AD) over the last 3 years in order to develop a study methodology of AD in Oriental Medicine. Methods : Using the Pub med on line site; search terms: atopic dermatitis, field as title/abstract, limitation as published in the last 3 years, only items with links to full text, Humans, Clinical Trial, English. I observed the study contents of all this research and focused on the classification of treatments. I also observed of AD clinical trials registered on a clinical trial site(www.clinicaltrial.gov) on 23rd of June, 2007: study contents, localization and study designs. Results : Through the Pub Med site, I found 169 articles. Classified according to study subject, the studies related to treatment were 114(67.5%); physiology, pathology and prevention 12(7.1%); Diagnosis and Evaluation(7.1%); psychological aspects including quality of life 10(5.9%); diet and management 10(5.9%); epidemiology 7(4.1%); and others 7(4.1%). However, the treatment study of herb-medicine as intervention showed only 1 article. Futhermore, it wasn't based on Oriental Medicine philosophy. In the clinical trial site, there were 31 studies in which patients were recruited or planned for the future. The study on efficacy and safety of the medicine produced 14 trials, 5 comparative trials, 2 phototherapy, 2 diagnosis, 6 physiology and pathology, and 2 epidemiology. The trial institutions were concentrated in U.S.A. Conclusion : I suggest we'd better try to make a good clinical guideline and standardization of diagnosis and herb-medicine in order to develop a clinical study methodology of AD as soon as possible in the future. Even though it 's very hard to find the study methodology, we should aim to achieve positive results and show the evidence of the efficacy and safety of herb-medicine treatment for AD using Oriental Medicine.

  • Objectives: This was to evaluate the current usage of three erythropoietin stimulating agents (ESA) and their efficacy for management of anemia in peritoneal dialysis (PD) patients with chronic kidney disease. Methods: It was a retrospective comparative study through review of electronic medical records of chronic kidney disease patients undergoing PD at a tertiary teaching hospital from January 1998 to June 2013. Results: Average administration frequency was 1.66 times/week in EPO group, 0.75 times/week in DA group, and 0.19 times/week in MPG-EPO group. At the first 4 weeks, there were significant differences in mean hemoglobin levels between EPO and DA groups ($9.25{\pm}1.28g/dL$, $10.02{\pm}0.95g/dL$ each, p = 0.018) and also in hemoglobin response rates (10.0%, 45.2% each, p = 0.008), but since after 4 week, there had been no significant differences. There also showed no significant differences in achievement of hemoglobin target between the two groups. When converted to MPG-EPO in EPO/DA groups, there showed a slight increase in hemoglobin levels of both groups. MPG-EPO was the highest compared with two other drugs by the average cost based on the average weekly dose. Conclusion: EPO, DA, and MPG-EPO showed similar effects in treatment of anemia of PD patients based on hemoglobin target range (11.0~12.0 g/dL) which NFK-K/DOQI guidelines suggest. Though the average cost of MPG-EPO was higher than the other two drugs, the number of PD patients using MPG-EPO has increased and it is thought that long half-life and low administration frequency of MPG-EPO have improved the compliance of PD patients who have to self-administrate.
