This study was performed to develop a scale of maternal conflict based on already established scales and the literature review. The major purpose of this study was to develop a scale of which contains difficulties which mother can feel to rearing her child and can be applied to mothers at home or employed mothers. 68 items were developed. For content validity test, the items were examined by 7 experts panel with Likert 4 scale. The 39 items were selected as high validity from 86% of the experts. The item number of each area and the misunderstanding words were corrected by advices of experts. 10 mothers again examined 39 items in order to correct the misunderstanding words and the long sentences. For reliability and factor analysis of 39 items, 496 mothers participated. 34 items were chosen because 5 items that corrected item-total correlation coefficient were lower than 0.2 were excluded by the result of reliability analysis. Factor analysis was done with 34items. 6 factors were classified higher than eigen value 1.0, 28 items were chosen because 6 items that factor loadings were lower than 0.4 were excluded. These factors were named as employment and caring for child(6 items), child education(5 items), support system for caring for child(4 items), interaction with mother and child(4 items), view of maternal role(5 items) and me as human being(4 items). Reliability analysis was done with 28 items. 1 item(36 number of factor 1) was excluded because corrected item-total correlation coefficient were lower than 0.2. Therefore, 27 items were chosen. Maternal Conflict Scale was contained 27 items. The corrected item-total correlation coefficient of 27 items were ranged from .2345 to .5240 and Cronbach alpha coefficient of those was .8207 by the results of reliability analysis. It can be evaluated that this scale had a high validity and reliability because of passing through an objective process of test.

Since the establishment of the national medical licensing examination board in 1992, the medical licensing examination system has changed enormously and this has had a number of impacts on examination services. All those reforms were aimed at improving the relevance and reliability of the test. Several attempts of the testing system have appeared in the new examination service, and which have also brought about the changes in the medical school curriculum such as introducing integrated courses instead of traditional subjects, using test scores as a reference to the post-graduation selection test. Some examples of changes in the examination system are as follows: 1) choosing three integrated test subjects and outlines of their reference content instead of 15 academic subjects, 2) adjusting the ratio of multiple choice question items to focus more on the problem solving level, 3) introduction of 'one-best answer' single set and 'extended matching type items, 4) item construction based on real clinical cases and real clinical materials. Recently, a clinical skill test system has been introduced to measure examinees' basic clinical skills competencies. Despite continuing efforts, the examination system still has many issues remaining to be solved. These problems include the differential weighting of test items, appropriate threshold for passing, and practicality of pre-testing to stabilize the passing rate and avoid the hazards of newness and undesirably difficult test items.

An investigation was carried out on a basis of the examination with a view to detecting the degree of microbial contamination for the 82 samples collected from the locally-sold liquid preparations. The results obtained are summarized as follows ; 1. Total viable Bacteria(TVB) per ml. in test sample shows min. 0 and Max. $8.0{\times}10^5$. Among the test samples, 2 items of Herb medicines have shown the highest bacterial contamination degree. 2. The number of unsuitable products are 9(11.0%) of the 82 items tested. Comparing with the study of 1971 (18 or 23.4% of 77 items), this fact suggests that the more than 50% decreasing tendency has come from the technical preventive efforts on bacterial contamination. 3. E. coli, Staph. aureus, and Pseudomonas aeruginosa could not be detected with the test sample. 4. The number of confirmable mycotic contamination in the test samples has been revealed as 17 items (20.7%). 5. Chiefly, the causative organisms of the contamination are proved to be bacilli and fungi broadly distributed in nature. 6. Generally, the neutrality of the pH had greatly increased the number of products unsuitable on the specification of TVB. pH >7.0 No. of unsuitable items 0/4 (0.0%) pH 6.0-7.0 No. of unsuitable items 4/9 (44.4%) pH 4.0-6.0 No. of unsuitable items 5/45(11.1%) pH <4.0 No. of unsuitable items 0/24(0.0%) 7. The viability of general bacteria has shown a rather decreasing tendency in time.

Objectives : The evaluation of academic achievement is pivotal for establishing accurate direction and adequate level of medical education. The purpose of this study was to firstly establish innovative item analysis technique of Item Response Theory (IRT) for analyzing multiple-choice test of herbology in the traditional Korean medicine education which has not been available for the difficulty of test theory and statistical calculation. Methods : The answers of 390 students (2012-2018) to the 14 item herbology test in college of Korean medicine were used for the item analysis. As for the multidimensional analysis of item characteristics, difficulty, discrimination, and guessing parameters along with item-total correlation and percentage of correct answer were calculated using Classical Test Theory (CTT) and IRT. Results : The validity parameters of strong and weak items were illustrated in multiple perspectives. There were 4 items with six acceptable index scores, and 5 items with only one acceptable index score. The item discrimination of IRT was found to have no significant correlation with difficulty and discrimination indices of CTT emphasizing attention of professionals of medical education as for the test credibility. Conclusion : The critical suggestions for the development, utilization and revision of test items in the e-learning and evidence-based Teaching era were made based on the results of item analysis using IRT. The current study would firstly provide foundation for upgrading the quality of Korean medicine education using test theory.

The pilot aptitude test so far has been conducted with a dichotomous concept of cognitive factor and non-cognitive factor, so it was not easy to explain concrete factors about pilot aptitude. Therefore, an integrated approach is needed to construct pilot aptitude test including all factors that can predict pilot aptitude. In previous study, we developed questionnaire items for the Pilot Aptitude Personality Test(PAPT) which can predict the flight training achievement through personality and personal characteristics. And those items were categorized as personality, cognition, and motivation factors. The flight training grades were correlated with all the test factors of the items, and the cognitive factors were high. As a result of the regression analysis, the total score of the three factors together accounted for 16% of the flight training grades. The results of the ANOVA showed that the cognition factors and motivation factors had significant effects on the completion of the flight training. The factors of PAPT predicted not only the completion of the flight training but also the flight performance. This is because the existing paper-pencil pilot aptitude test can only discriminate the flight training completion status. This is also a result of the fact that the introductory flight training consists of various factors including not only basic cognition but also personality and motivation.

The aim of this study is to evaluate the clinical competence of medical student using short case test items. Development of short case test items with definition of an assessment of subject, choice of clinical stations sampling, identification of components of clinical competence to be evaluated, and assessment of practicability and results exploitation. For the last three years 28, 48 and 30 topics were developed annually. Among them 20, 23 and 23 topics were selected. About 50 students were examined annually. The mean score was 72.7, 57.1, 64.3 respectively. The mean preparation time of the students for the examination was 9.8 hours. About 60% of the students prepared the test in small group activity. Our experience suggests that short case test items be feasible for evaluation of student learning in Plastic Surgery. This method should be considered as a useful tool to assess medical student's competence or even an examination for board certification.
