This is the evaluation report of clinical competence of undergraduate medical students in Plastic Surgery field using OSCE(Objective Structured Clinical Examination) executed in three years. OSCE comprises of assessment of subject, choice of clinical stations sampling, identification of components of clinical competence to be evaluated, the level of performance required, development of specification table, editing of OSCE presentation page and assessment of practicability and results exploitation. About fifty students were examined annually. Seven station stimuli with simulated patient participation were carried out. The mean OSCE score was $82.3{\pm}6.19$. The reliability of the total station was 0.72. The examination shows a positive response to the OSCE. Our experience shows OSCE's feasibility for Plastic Surgery during the initial course of education. Referring to our experiences, the Korean Society of Plastic and Reconstructive Surgeons (KPRS) applied the OSCE test for Korean Plastic Surgery Board Certification

The purpose of this study was to find out the present condition of clinical practice and to develop a scheme on the efficiency of clinical practice for nursing education in junior college of nursing in korea. This study was conducted by 2 sections. Ist section was to find out the present condition of clinical practice to 42 directors of nursing collegd and data were collected July 8 to September 30, 1988. 2nd section wat to develop a scheme on the efficiency of clinical practice for nursing education and subjects were nursing professors 258: and clinical nurses 223 in 42 junior nursing colleges their clinical settings in korea. So total subjects were 481. Data were collected july 8, 1988 to June 30, 1988 and were analysed to get the mean, standand deviation, frequency, percentage, t-test, x-test used by SPSS - pc. Major findings were as follows: 1. The present condition of clinical education in junior college of nursing in Korea. 1) 32 colleges (76.2%) were managed by a-yeas system. 2) 25 colleges (59.5%) were performed by individual practice for each subject. 3) 4 weeks interval between class education and clinical education was a major type among total colleges(36.6%, J5 colleges) 4) 30 colleges (71.4%) provided clinical education for all subjects that should be practiced. Nursing administration wes not practiced in 5 colleges (41.9%) among the remainder(12 colleges). The main cause that all practice subjects were not practiced was the lack or absence of suitable clinical settings(8 colleges. 66.7%) 5) 18 colleges (42.9%) responded that a clinical educator was, subject-charged professor. 6) 12 colleges (29.3%) responded that a clinical instructor was in charge of 6~10 students. 7) The evaluation ration ratio(professor to head nurse) by each evaluator was mostly 50% to 50 % and 60% to 40%, respectively 11 colleges(27.5%) The most common evaluation methods were evaluation by head nures, report, presence, conference (11 colleges, 27.5%) 8) The field carrier of professor was mostly 2 years (79 persons, 20.7%) and mean was 3.2 years. The education carrier of a professor was mostly over than 6 years (261 persons, 66.4%) and mean was 9.2 years. The charge hours per-week of a professor were mostly 16-18 hours (16 persons, 131.8%) 9) 34 colleges (82.9%) approved that clinical practice hour was class hour and 18 colleges (43.9 %) counted that 2 hours of clinical education equaled 1 hour of class education. 2. A study 'on the efficiency of clinical practice for nursing education. L) general characteristics of subjects were as follows: kung-sang province (145 persons, 30.5%), 30-34 years (190 persons, 39.8%), graduated degree (245 persons, 51.5%), 6-10 years of carrier (199 persons, 41.4%) were the majority. 2) suitable clinical setting was responded the systematic ward with responsible clinical educator by 210 persons(43.8%) The response by working field of subjects showed a significant difference (p< 0.01) 3) 259 subjects (54.0%) responded that the desirable qualfication of clinical instructor was 3-5 years of clinical experience with master degree or higher. 4) The mean score of desirable quality degree of clinical instructor was 3.43 professors, score (3.54) was significantly higher than clinical nurses' (3.28) (p<0.01) 412 subjects (86.0%) responded that the insufficient guality of instructor was improved by continuing to seek more new information in reference. 5) 196 subjects (41.4%) responded that desirable qualification of head nurse was more than 2 years of head position among 5 years of clinical experience. The response by working' field of subjects showed a significant difference (p<0.05) 6) The mean score of desirable quality degree of head nurse was 3.18 Clinical nurses' score(3.38) was significantly higher than professors' (3.01) (p<0.01) 419 subjects (87.8%) responded that the insufficient of head nurse was improved by continuing relationship with instructor and being responsible from planing of clinical education. 7) The mean score of performance level of the desirable clinical education guide incollege was 2.91 Professors' score (2.96) was significantly higher than clinical nurses' (2.84) (p<0.01) 340 subjects (71.1%) responded that the possible resolution for poor performance was the more specified syllabus of clinical education and the satisfiable orientation for students. 8) The mean score of performance level of the desirable clinical education guide in hospital was 3.03 9) 141 subjects (29.6%) responded that the desirable clinical evaluator was the group of professor, head nurse, staff nurse. Response by working field of subjects was a significant difference (p< 0.05) 10) The mean score of performance level of the evaluation content needed in clinical education was 3.50 Clinical nurses' score (3.56) was significantly higher than professors' (3.45) (p<0.01) 11) 433 subjects (90.2%) responded that6 desirable evaluation method for clinical education was the presence. 12) The mean score of performance level about how personal difference among clinical educators was minimized was 2.89 and response by working field of subjects was not significant. The cause of poor performance was too much workload at clinical settings and too many students st colleges by 386 subjects (81.1%).

Since its first release in 2007, the National Institute of Food and Drug Safety Evaluation (NIFDS) has provided pharmacogenomic and comparative information specific to Koreans to allow regulatory reviewers and researchers to adapt their working practices to pharmacogenomics. The highlights of this year's additions include "Drug Information", "Gene Information" and "Pharmacogenomic information in the drug labels" sections. These new additions provide information on 737 genes, 719 drugs and pharmacogenomic data of the labels or relabels of 253 approved drugs as of November 2008. The latest version of the Korean Pharmacogenomic Database (KPD, release 2.0) has expanded significantly since its previous release. More SNP and haplotype information has been added to the database with the latest version of the KPD containing approximately four times as many SNPs and haplotypes than the previous version (719 vs. 152, and 30 vs. 7 respectively). Through the "SNP" and "Haplotype" sections, the KPD provides unique Korean SNP and haplotype information as well as comparative information of other populations (Japanese, Chinese, European, African) to offer a range of pharmacogenomic data that can help reviewers and the public understand pharmacogenomic information. The quality and quantity of information in the KPD has also been improved considerably. This data can be found at: http://www.nitr.go.kr/nitr/contents/m134700/view.do/.

The purpose of this study is to evaluate and compare the quality of digital X-ray imaging system. The image quality evaluation was conducted By using Modulation transfer function indicating the quantitative resolution of the image and the noise power spectrum showing the noise characteristics. Using a IEC61267 radiation quality was applied to the geometry to be used in clinical and geometry presented in IEC62220-1 and Additional filter, grid, the clinical dose and the MTF value of edge phantom was measured. Result of the MTF corresponding to each item(Grid, Filter, SID, kVp, mAs), the clinical condition 100cm, 180cm, measurements of the spatial frequency of the MTF IEC62220-1Geometry 150cm became similarly apparent, rather spatial frequency was also the case high in clinical conditions 100cm. NPS results, as the dose(mAs) is increased, NPS showed that reduced. The image quality evaluation using IEC61267 the Radiation quality, Image quality of the video using the clinical conditions Geometry than image quality evaluation using IEC62220-1Geometry was better. It shows that MTF and NPC in IEC and clinical condition were not significantly different. In order to apply the evaluation method of image quality applied with clinical conditions rather than the future method, to be presented evaluation of IEC standard, based on the results of the image characterization studies in this paper, the methods that shows good quality of spatial resolution and decrease NPS value as the least dose, used suitable parameters for whether or not using added filter, grid, change SID and clinical quality(kVp), dose(mAs) etc should be found. then It is believed to be able to properly maintain the actual quality of the image of the digital radiographic imaging system in clinical.

In clinical trials with repeated measurements, the time-averaged difference (TAD) may provide a more powerful evaluation of treatment efficacy than the rate of changes over time when the treatment effect has rapid onset and repeated measurements continue across an extended period after a maximum effect is achieved (Overall and Doyle, Controlled Clinical Trials, 15, 100-123, 1994). The sample size formula has been investigated by many researchers for the evaluation of TAD in two treatment groups. For the evaluation of TAD in multi-arm trials, Zhang and Ahn (Computational Statistics & Data Analysis, 58, 283-291, 2013) and Lou et al. (Communications in Statistics-Theory and Methods, 46, 11204-11213, 2017b) developed the sample size formulas for continuous outcomes and count outcomes, respectively. In this paper, we derive a sample size formula to evaluate the TAD of the repeated binary outcomes in multi-arm trials using the generalized estimating equation approach. This proposed sample size formula accounts for various correlation structures and missing patterns (including a mixture of independent missing and monotone missing patterns) that are frequently encountered by practitioners in clinical trials. We conduct simulation studies to assess the performance of the proposed sample size formula under a wide range of design parameters. The results show that the empirical powers and the empirical Type I errors are close to nominal levels. We illustrate our proposed method using a clinical trial example.

The presence of implant-prosthesis misfits can cause various complications. It is very important to detect misfits to prevent such complications. There are various evaluation methods for misfit assessment including clinical methods and laboratory in vitro methods. The clinical misfit evaluation includes radiographic analysis, visual observation, probing, Sheffield test, evaluation with disclosing materials, and screw resistance test. The laboratory in vitro evaluation method includes indirect modelling evaluation and direct metrological visualization. Of the indirect modelling methods, photoelastic stress analysis, finite element analysis, strain gauge analysis, and microbial colonization analysis were reviewed. Of the direct metrological visualization, microscopic analysis, 3-D photogrammetric analysis, coordinate measuring analysis, and radiographic analysis were reviewed. In this review, the characteristics, advantages and disadvantages of each method were evaluated.

A descriptive-explanatory design was employed in this study. The purpose of this study was identify the level of assertiveness and clinical stress and the relationships between assertiveness and clinical stress in nursing students. A convenient sample of 143 nursing students was used for the study. The results of this study are as follows : 1) The level of assertiveness of nursing students was 3.65 in domain of contents, 3.68 in domain of voice, and 4.13 in domain of body language. Thus the level of asertiveness of nursing students was higher in body language. 2) The level of clinical stress of nursing students was 3.73 in domain of clinical education and evaluation by professors, 3.59 in domain of nurses, 3.32 in domain of human relationships, and 3.30 in domain of environment. Thus the level of clinical stress of nursing students was higher in clinical education and evaluation by professors. 3) The assertiveness of nursing students was found significantly related to human relationships. 4) The clinical stress of nursing students was found significantly related to satisfaction of nursing, satisfaction of clinical practice and priority of candidate for nursing. 5) The assertiveness of nursing students was not found significantly related to clinical stress in nursing students.

Purpose: The COVID-19 pandemic has increased the importance of nurses' clinical performance, and accordingly, nursing educators have emphasized students' clinical practice and performance. This study developed a Clinical Practice Self-Efficacy Scale for nursing students and examined its psychometric properties. Methods: The authors reviewed instruments for selecting items for the scale in the areas of clinical skills, communication, infection control, safety, and nursing process. After preliminary items were selected, ten experts consisting of nursing professors and clinical nurses reviewed the items considering Korean clinical and educational situations. The data for the psychometric evaluation was collected from 257 nursing students in their 2nd, 3rd, and 4th years and then analyzed. Results: The confirmatory factor analysis showed that the goodness of fit of this scale with five factors represented by 40 items was appropriate. The significant positive correlations with general self-efficacy indicated sound construct validity. The senior nursing students showed higher scores than others, as we expected. Cronbach's alpha was .94. Conclusion: The Clinical Practice Self-Efficacy Scale is appropriate for measuring Korean nursing students' self-efficacy of clinical practice. It is expected to act as a good tool to measure the effects of clinical practice education.

Objectives: With more and more health economic evaluations being performed in many countries, the question of whether the results from the foreign studies can be transferred to other country is becoming important. The objective of this study was to conduct a case study using three transferability diagnosis tools for economic evaluation on rheumatoid arthritis. Methods: Three diagnosis tools were used to assess transferability: Welte's tool, Boulenger's and Urdahl's. Five researchers who have experience on economic evaluation made consensus on the evaluation through the semi-delphi method. Results: With Welte's tool, absolute and relative prices in healthcare, practice variation, health-status preference, productivity and work-loss time were evaluated as biased. The transferability information score by Boulenger's was 85.9%, which means qood quality reporting. In case of Urdahl's, research questions were well defined and reporting was transparent and explicitly stated. However, both the relevance of data inputs to Korea and robustness of model were relatively low. In conclusion the UK study on rheumatoid arthritis could be partially transferable to Korea, and will need modeling-based adjustments.
