Korean Journal of Family Medicine 2017;38(6):315-321
A prescriptive model approach in decision making could help achieve better diagnostic accuracy in clinical practice through methods that are less reliant on probabilistic assessments. Various prescriptive measures aimed at regulating factors that influence heuristics and clinical reasoning could support clinical decision-making process. Clinicians could avoid time-consuming decision-making methods that require probabilistic calculations. Intuitively, they could rely on heuristics to obtain an accurate diagnosis in a given clinical setting. An extensive literature review of cognitive psychology and medical decision-making theory was performed to illustrate how heuristics could be effectively utilized in daily practice. Since physicians often rely on heuristics in realistic situations, probabilistic estimation might not be a useful tool in everyday clinical practice. Improvements in the descriptive model of decision making (heuristics) may allow for greater diagnostic accuracy.

PURPOSE: The purpose of this study was to explore changes in the test items in the preparation book for the national qualifying examination. Test items which developed in the year 2000 and 2004 through nationwide faculty workshop in Fundamentals of Nursing were examined. METHOD: Test items for the national qualifying examination for 2000 and 2004 in Fundamentals of Nursing were analyzed using frequencies and percent. RESULTS: The test items for the national qualifying examination for 2004 in Fundamentals of Nursing showed an increase in the number of test item over the year 2000. According to McGuire's taxonomy, domains of the test items in 2000 were recall(65.1%), interpretation (22.0%), and problem solving(12.9%) in that order. In 2004 items for the recall domain(74.7%) increased 9.6% above the level of 2000, and interpretation and problem solving domains showed a slight decrease. With regard to type of test items, the proportion of A type in 2004 was the same with 37.6% as 2000, and that of K type(61.5%) increased by 0.7% over the year 2000(60.8%). CONCLUSION: The test items for the national qualifying examination of 2000 and 2004 were not different except for the increase in the number of test items.

Environmental pressures from such sources an economic condition, the government and inter-institutional competition create managerial challenges. Economic pressures may be forcing dietetic dept, in hospital to utilize cost, benefit analysis to assist them in their problem solving. Cost, benefit analysis have been widely used in business, industry and many other fields with only limited application to foodservice. Due to the lack or this information the purposes of this study were to identify use of cost, benefit analysis in hospital foodservice system to evaluate the economic efficiency of alternatives, and to make recommendation for operation system change. Using the cost?benefit method, cash flows are separated into cost and benefits. For an alternative to be selected, indicators, such as NPV, benefit-cost ratio (B/C ratio) with 5% discount rate per annum. The sensitivity analysis was also conducted with difference rate 3%, 7% respectively and reduced employee payroll change. The result of this study can be summarized as follows : 1. The total cost of investment for operation system change was 390,570 thousand won and the total benefit through operation system change was 865,808 thousand won. 2. Net present value(NPV) for 5 years was 475,239 thousand won and benefit-cost ratio was 2.22. 3. In sensitivity analysis with different discount rate 3%, 7%, benefit-cost ratio was 2.25, 2.18 respectively, with total reduced employee payroll change, benefit-cost ratio was 2.86. In conclusion, total benefits were exceeded total costs. Therefore, the project of operation system change in hospital foodservice was found to be economically efficient.

PURPOSE: The purpose of this study was to identify the relationship among hesitation factor of questions, critical thinking disposition, and problem solving. METHODS: Data were collected from 370 students at a university in D city using a structured questionnaire from April 1 to April 15, 2015. It was analyzed with frequency analysis, descriptive statistics, t-tests, ANOVA, and correlation analysis. RESULTS: Subjects scored an average of 2.62+/-.52 for hesitation factor of questions, 3.53+/-0.42 for critical thinking disposition, and 3.44+/-0.44 for problem solving. There were significant differences in the three variables according to satisfaction with major, self-expression, and interpersonal relationships. In addition, hesitation factor of questions exhibited a significant difference between genders. Hesitation factor of questions had a negative relationship with critical thinking disposition (r=-.23, p<.001) and with problem solving (r=-.34, p<.001). In addition, there was a statistically significant positive correlation between critical thinking disposition and problem solving (r=.69, p<.001). CONCLUSION: In order to improve critical thinking disposition and problem solving, we need to generate a lot of questions to the student's inside. We also need to develop appropriate teaching methods so that this can be expressed by the actual question coming from the control hesitation factor of questions.

5.Usability of Extended-matching Type Items in the Korean Medical Licensing Examinations (2002, 2003) .
Korean Journal of Medical Education 2004;16(2):219-226
PURPOSE: In 2002, extended-matching type (R-type) items were introduced to the Korean Medical Licensing Examination. To evaluate the usability of R-type items, the results of the Korean Medical Licensing Examination in 2002 and 2003 were analyzed based on item types and knowledge levels. METHODS: Item parameters, such as difficulty and discrimination indexes, were calculated using the classical test theory. The item parameters were compared across three item types and three knowledge levels. RESULTS: The values of R-type item parameters were higher than those of A- or K-type items. There was no significant difference in item parameters according to knowledge level, including recall, interpretation, and problem solving. The reliability of R-type items exceeded 0.99. With the R-type, an increasing number in correct answers was associated with a decreasing difficulty index. CONCLUSION: The introduction of R-type items is favorable from the perspective of item parameters. However, an increase in the number of correct answers in pick 'n'-type questions results in the items being more difficult to solve.

In an effort to evaluate the usage of preceptorship in a department of family medicine, we analyzed the data which gathered during 10 months, from July 1990 to April 1991. The analyzed results were as follows ; 1. The number of precepting per preceptor was 3.5 during one day. 2. In the clinical learning, the residents needed instruction most frequently in the process for diagnosing the problems of their patients. 3. For the purpose of evaluating the teaching behavior of preceptors, we asked to 21 residents and 8 preceptors of the department who experienced the preceptorship for responding a questionnaire, which contained 30 questions. Residents perceived that the most contributable teaching behavior was "deals with students in a friendly, outgoing manner". Preceptors answered that behavior as "emphasizes problem solving approaches rather than solution per se". About the least contributable teaching behavior, residents and preceptors agreed that it was "emphasis on his/her personal research". For further improvement in clinical instruction and its evaluation, it would be necessary to develop a collaborative methodology for clinical instruction and to organize an ongoing professional communication.

PURPOSE: This study was done to analyze core competencies affecting critical thinking ability of student nurses. Core competencies investigated in this study were problem solving ability, communication ability and self-directed learning ability. METHOD: Data were collected from a convenience sample of 322 student nurses in 2 provinces during the period from May 21 to June 8, 2007. Critical thinking, problem solving ability, communication ability and self-directed learning ability were measured using the Disposition towards Critical Thinking Scale by Park (1999-a) and the Core Competencies Scale by Lee (2003). Descriptive statistics and correlation coefficients with the SPSS WIN 12.0 program were used to analyze the data. RESULTS: There were significant differences in the critical thinking according to grade, type of high school, experience with PBL, preference for lecture-based learning, preference for discussion and perceived logicality. The score for critical thinking showed significantly positive correlations with scores for problem solving ability (r=0.54, p=0.00), communication ability (r=0.56, p=0.00) and self-directed learning ability (r=0.54, p=0.00). CONCLUSION: The results of this study suggest that problem solving ability, communication ability and self-directed learning ability are significant factors affecting critical thinking in student nurses.

BACKGROUND: To this date, efforts to develop effective methods for the education of diabetic patients have been limited. The important goal of self-management and weight control for diabetic treatment can not be attained without long and intensive period of education. This study was undertaken to assess the effectiveness of an intensive educational program, of behavior and diet control, which was carried out on subjects with type 2 diabetes, on an out-patient basis. We compared the effectiveness of an intensive education programme with that of a conventional education programme for the self-management of type 2 diabetic patients. METHODS: Subjects with type 2 diabetes were randomly selected, and allocated to one of two groups. One group received a conventional education programme of self-management(the CE group), and the second group received an intensive education programmes for three months, after which the effectiveness of the programmes were evaluated. RESULTS: 1) The levels of fasting blood sugar(FBS), postprandial 2 hour blood sugar(PP2h) and HbA1c were significantly lowered in both groups following the intervention(p<0.05). In the IE group, the FBS declined from 12.4nmol/L to 7.7nmol/L, PP2h declined from 20.3nmol/L to 10.9nmol/L, and the HbA1c showed a similar decline from 9.4 to 7.0% after intervention(p<0.05). In the CE group, the FBS declined from 10.9 to 9.4nmol/l, the PP2h decreased from 17.1 to 14.6 nmol/l, and the HbA1c also decreased from 8.5 to 7.3% after intervention(p<0.05). The decrease in the FBS and HbA1c following the educational intervention was more pronounced in the IE group than the CE group (p<0.05). 2) The effectiveness of the education programmes in promoting appropriate dietary behavior in the diabetic subjects was assessed by a scoring system in three parts: a regularity score, a balance score and an attitude score. From a comparative study of the three scores, the patients attitudes were observed to be much improved in both the groups following the intervention compared to before the programmes, but the balance and total scores were significantly higher in the IE group than the CE group(p<0.05). CONCLUSION: We can conclude that the intensive diabetic education programme is more effective than a conventional programme, not only in improving the patients' levels of glucose, HbAlc, and dietary score, but also the diabetic patients self-control abilities, promoting behavioral change, and prompting problem solving capabilities in respect to the everyday problems that they have to face throughout their lives.
