Aproximación teórica a las incoherencias grafo-corporales en los procesos de recogida de muestras en pericia caligráfica / Theoretical approach to grapho-corporal inconsistencies in the processes of sample collection in handwriting expertise / Abordagem teórica das inconsistências grafo-corporais nos processos de coleta de amostras em perícias de caligrafia

La recogida de muestras indubitadas al momento de elaborar un cuerpo de escritura a una persona, es un proceso de suma importancia en la pericia caligráfica. Existen parámetros por los que se rigen los peritos calígrafos al confeccionar dicho cuerpo de escritura, que se centran de forma general en la posición del escribiente, la velocidad escritural, la espontaneidad, cantidad de muestras, entre otros. Sin embargo, el escribiente puede intentar alterarlo o manipularlo de diferentes formas, normalmente intentando dificultar la labor pericial. Así, existen diversos elementos que indican a un experto en grafística que se está intentando modificar la escritura o firma durante este proceso desde el punto de vista técnico. En este sentido, el objetivo de este estudio es resaltar la importancia de recopilar un cuerpo de escritura con todas las garantías para que pueda tratarse como un documento incuestionable, además de destacar la relevancia de que el perito tenga la capacidad de confirmar la sinceridad del escribiente, tanto mediante el análisis de su escritura (grafología) como a través del análisis de su comunicación no verbal en el momento de escribirlo. Se ha utilizado una metodología cualitativa, usando la técnica de información documental, mediante la recopilación de información para su estudio y análisis, así como de monografías, manuales de estudio y artículos científicos.

The collection of indubitable samples when a corpus of handwriting is taken from a person is an extremely important process in handwriting expertise. There are parameters by which handwriting experts are governed when making such a writing corpus, which generally focus on the position of the scribe, writing speed, spontaneity, number of samples, among others. However, the scribe may try to alter or manipulate it in different ways, usually in an attempt to hinder the expert's work. Thus, there are several elements that indicate to a handwriting expert that an attempt is being made to modify the handwriting or signature during this process from a technical point of view. In this sense, the aim of this study is to highlight the importance of compiling a handwriting corpus with all the guarantees that it can be treated as an unquestionable document, as well as highlighting the importance of the expert having the ability to confirm the scribe's sincerity, both through the analysis of their handwriting (graphology) and through the analysis of their non-verbal communication at the time of writing. A qualitative methodology has been used, using the documentary information technique, by means of the collection of information for study and analysis, as well as monographs, study manuals and scientific articles.

Can learning outcomes in cognitive domain be assessed effectively using multiple choice questions? A study in an undergraduate pharmacy curriculum

Background: The widespread use of multiple choice questions (MCQ) in examinations is attributed to its logistical advantage and broad coverage of content within a short duration. The end-of-semester examinations for several modules in the pharmacy programme previously employed a combination of written examination tools including MCQ, short answer questions (SAQ) or essays for assessing learning outcomes in the cognitive domain. Concerns regarding assessment fatigue and subjectivity in marking have led to a review of the assessment formats in the examinations. Various types of MCQ were consequently introduced as the only assessment tool. This study was conducted to evaluate the performance of students in the examinations as a result of the change. Methodology: Analyses were carried out on the end-ofsemester examination results of two cohorts of students for each module, one based on a combination of MCQ, SAQ or essay and the other based on MCQ alone. The class means were compared, and t-test was used to determine the difference between the performances. Results: Although the difference in the mean scores of the two groups is statistically significant in 13 of the 20 modules, the difference is less than 5% in 10 modules. Conclusion: The findings provide evidence that wellconstructed MCQ can effectively assess cognitive skills.

The Correlation between the Scores of Written Examination, the Clinical Clerkship Examination, the Clinical Skill Assessment, and the Graduation Examination of the Medical Students / 한국의학교육

PURPOSE: The aim of this study was to investigate correlations between medical student scores on 4 examinations: the written examination, clinical clerkship examination, clinical skill assessment, and graduation examination. METHODS: Scores for 51 students who entered Daegu Catholic Medical School in 2005 on the written examination, clinical clerkship examination, clinical skill assessment, and graduation examination were included. Correlations between the scores were analyzed statistically. RESULTS: The scores on the written examination showed a strong correlation with those of the clinical clerkship assessment (0.833) and graduation examination (0.821). The clinical clerkship assessment scores correlated significantly with graduation examination scores (0.907). In addition, clinical skill assessment scores correlated with the written examination (0.579), clinical clerkship examination (0.570), and graduation examination (0.465) scores. CONCLUSION: Overall, the correlation between the scores on the clinical clerkship examination and the written examination was more significant than the correlation between scores on the clinical clerkship examination and clinical skill assessment. Therefore, we need to improve the evaluation method for the clinical clerkship examination and clinical skill assessment.

The Correlation between CPX and Written Examination Scores in Medical Students / 한국의학교육

PURPOSE: The purpose of this study is to analyse the gap between what medical students learn in theory and their clinical performance in reality. The hypothesis is that students with high written examination scores will also perform better in the Clinical Performance Examination (CPX). METHODS: 128 Catholic University medical students in year four took the CPX on 24th, September 2005. 40 standardized patients (SPs) were involved as assessors. Each student performed five CPX cases. The students' written examination scores of year three, SPs' assessment scores were used as instruments. Students were divided into two groups (A and B) and each group consisted of 64 students. Correlation between the written examination scores and the CPX scores, CPX case scores and related written examination scores were analysed. RESULTS: Overall, there was no significant correlation between the CPX score and the written examination scores in total, but significant correlations were shown in family medicine CPX scores of both groups A and B (pearson=.308, p=.199; pearson=.258, p=.051). From the analysis of the CPX cases and related written examination scores, group A showed significant correlation in three out of the five cases. No significant correlation seen in group B. CONCLUSION: It can be concluded that large gaps still exist between theory and practice. Some suggestions are given to minimize these gap.

Correlation of CPX Scores with the Scores of the Clinical Clerkship Assessments and Written Examinations / 한국의학교육

PURPOSE: Recently, the clinical performance examination (CPX) using standardized patients has been introduced to several Korean medical schools. The purpose of this paper is to evaluate the correlation of CPX scores with the scores of other clinical clerkship assessments and written examinations. METHODS: We evaluated the correlation of the scores of CPX, which was administered to third-year medical students (n=230) at Seoul National University College of Medicine in January 2005, with the scores of a slide examination in internal medicine, an objective structured clinical examination (OSCE) in pediatrics and obstetrics/gynecology, and the written examinations in internal medicine and general surgery. RESULTS: CPX scores showed a mild correlation with the scores of the slide examination in internal medicine and OSCE in pediatrics and obstetrics/gynecology (r=0.19, 0.28, 0.30). CPX scores were also mildly correlated with written examination scores in internal medicine but not associated with those in general surgery. CONCLUSION: Considering the mild correlation of CPX scores with scores of other clinical clerkship assessments and written examinations, CPX should be affirmatively considered as an examination complementary to previous examinations.

A Correlation between the Year Five Medical Students' Scores on Written Examinations of Clinical Sciences and the Scores on OSCE / 医学教育

Recently, as the practical training for clinical skills are extensively introduced in the curriculum of medical schools, the objective structured clinical examinations (OSCEs) is taken to assess the clinical skills of trainees. However, there have been very few papers mentioned about correlation between scores on a written examination of the clinical sciences and those on OSCE in Japan. In this study, to compare these of two kinds of examinations in year five medical students of Yamaguchi University, their scores of the stations of OSCE and those of the written examinations of clinical sciences which seemed to correlate stations of skill's examinations were studied statistically. As a result, there were no statistical significances in each scores between skill's evaluations and written tests. This results that these two examinations estimated the different abilities of students on the taxonomy of medical education. Moreover, OSCE is reconfirmed to be identical as an evaluative method of clinical skills. Now, new medical educational systems should be introducted for the training of skills and attitude for students.
