  • The purpose of this study is to identify the item characteristics that are supposed to affect item difficulty and to estimate the regression equations for predicting item difficulty of mathematics in the College Scholastic Ability Test(CSAT). We selected six variables related to item characteristics based on learning theories: contents, cognitive domain, novelty, item type, number of concepts, and the amount of computation. With data of the CSAT mathematics test administered in 2004-2006, item difficulty was regressed on the six variables, the location of an item, and the item writer's judgment on difficulty. The novelty of an item was found to be a statistically insignificant variable in explaining item difficulty. Four regression equations with different sets of independent variables could explain $70%{\sim}80%$ of the item difficulty variance and were validated as predicting item difficulty of the mock CSAT in 2006.

  • The study aimed at determining the identity of mathematics essay test in the university entrance examination. For this purpose, a document research was conducted for higher order thinking and mathematics essay ability and it analyzed the goal of assessment and the tendency of problem settings and looked into mathematics essay problems of twenty-five universities. As a result, the study found out that evaluation factors of mathematics essay test requires higher order thinking ability including mathematical knowledge and essay ability such as mathematical knowledge, understanding, problem solving, logical and critical thinking, creative ability, power of expression, argument skills. Also, problems from previous mathematics essay tests were set mainly to assess mathematical knowledge, understanding and problem solving. Based on the findings, the past mathematics essay tests in university entrance examination in Korea that require logical and critical thinking, creative ability, power of expression, argument skills were a rather small percentage of questions.

  • This study is the analysis of the concepts and the characteristics of the mathematics section of the College Scholastic Ability Test. The study starts with division of the history of the College Scholastic Ability Test into four periods. These are Introduction Period(school year 1994-1996), Adjustment Period(school year 1997-2004), Development Period(school year 2005-2011) and Conversion Period(up to present since school year 2012). The periodical division of the Mathematics section is considered as identical with that of the College Scholastic Ability Test. So we investigate the characteristics of the Mathematics section through the periodical classification. This study also proposes some tasks for the future Mathematics section of the College Scholastic Ability Test.

  • This study developed and evaluated a school adjustment program for children from multi-cultural families. The program was developed to enhance Korean language ability and adjustment to school for children from multi-cultural backgrounds. 14 preschool children (5 boys and 9 girls) participated in this program. The effect of this program was assessed through a preschool-children's receptive and expressive vocabulary test as well as through a reading ability test. Results showed there was a significant experimental effect (p<.05) in receptive and expressive vocabulary test scores. After the experiment, children showed higher scores in the receptive and expressive vocabulary test than before. Results of the program evaluation revealed this program was helpful for promoting Korean language ability in children and assisted their adjustment to school for children from multi-cultural backgrounds.

  • Purpose: The purpose of this study was to identify factors that affect nursing students' clinical practice ability. Methods: The data were collected from 303 nursing students who had more than 500 hours of experience in clinical practicum at 4 universities in Seoul and the metropolitan area. The instruments consisted of 27 items of critical thinking, 19 items of professionalism, 40 items of self reported leadership, 20 items of communication evaluation tool, and 61 items of nursing practice performance evaluation. Results: For the clinical practicum, most difficult for nursing students were cardiopulmonary resuscitation, fecal enema, stoma care, and blood transfusion. Clinical practice abilities were positively correlated with nursing professionalism(r=.26, p<.001), leadership (r=.16, p=.007) and critical thinking(r=.12, p=.031). Professionalism(${\beta}=.32$, p=.001) was the most significant factor influencing the clinical practice ability of nursing students. Critical thinking was the second largest factor but not significant(${\beta}=.16$, p=.058). Conclusion: The findings suggest that the nursing curriculum should include nursing knowledge and nursing skills as well as various case-based or field-based decision making training programs to cultivate professionalism, critical thinking and other abilities for clinical practice.

  • Purpose: The purpose of this study was to evaluate the educational outcome of applied integrated curriculum in a nursing college. In order to evaluate the educational outcome students' ability was surveyed for the four main elements of the curriculum. Four main elements were ability in application of nursing process, communication skill, critical thinking disposition, and competence in nursing profession. Method: The subjects were 97 nursing students who had been educated by the integrated curriculum for 4 years. Data were collected using self-report questionnaire on Dec. 6, 2006, and analyzed by using ANOVA, t-test, and pearson correlation coefficient.

  • The need for remanufacturing ships and various mechanical components continues to increase along with environmental problems. Research on remanufacturing is being carried out in various fields, but research on cleaning is quite insufficient. In particular, there is no research on the cleaning-ability of diverse mechanical components. In order to increase the life cycle of mechanical components, remanufacturing must be considered from the step of design. Particularly, it is also very important to evaluate the degree of easiness in cleaning to remove various pollutants generated by long-term use quickly as well as easily. In this study, the degree of easiness in cleaning is defined as cleaning-ability. In fact, remanufacturing components can be easily done only when cleaning-ability is set high from the step of design. The purpose of this study is to evaluate the cleaning-ability of ships and various mechanical components. The details of easiness in cleaning are cleaning and drying identification, accessibility to cleaning tools, convenience in cleaning, and convenience in drying. This study presents a quantitative procedure to evaluate cleaning-ability, derived various factors influencing each of the details of easiness and their ranges, and gave scores to the factors according to their ranges. The weight was also calculated for the details of easiness in cleaning and the factors. Lastly, this researcher suggests a scoring procedure to evaluate cleaning-ability quantitatively and the total weight of cleaning-ability.

  • The use of advanced electronic security system is growing quickly to protect properties and life. However, customers cannot select appropriate configuration of the system because there are no objective evaluation methods to measure the security ability of the system. Furthermore, the system suppliers cannot propose quantitative value of security ability of the system. This study suggests an objective evaluation and selection method that customers and suppliers can use to base his or her decision when choosing the most appropriate configuration of the system. Our method identifies 6 characteristics and 20 sub- characteristics of the electronic security system, calculates their weights, and decides the best configuration. We use AHP (Analytic Hierarchy Process) to assign the weights of characteristics. Finally, this paper gives an example to compare four alternative configurations of the system.

  • In this paper, we construct an automatic evaluation system of psychological feeling for corporate identity (CI) symbol mark based on a fuzzy neural network technique. The system is modelled by trainable fuzzy inference rules with several input variables (qualitative and quantitative design components of CI symbol mark) and a single output variable (consumer's feeling). The back propagation learning algorithm, which is a conventional learning method of multilayer feedforward neural networks, is used for parameter identification of the fuzzy inference system. The learning ability to train data and the generalization ability to test data are evaluated for the proposed evaluation system by computer simulations.
