Background and Objectives: Mild cognitive impairment (MCI) is a disorder that usually occurs in the elderly, leading to dementia in some progressive cases. The purpose of this study is to examine the utility of central auditory processing tests as early diagnostic tools for identifying the elderly with MCI. Subjects and Methods: This study was conducted on 20 elderly patients with MCI and 20 healthy matched peers. The speech perception ability in a quiet environment and in the presence of background noise and also temporal resolution were assessed by using Speech Perception in Noise (SPIN) and Gap in Noise (GIN) tests, respectively. Results: The results indicated that the ability to understand speech in a quiet environment did not differ significantly between the two groups. However, SPIN at the three signal-to-noise ratios and the temporal resolution scores were significantly different between the two groups (p<0.001). Conclusions: Individuals with MCI appear to have poorer speech comprehension in noise and a lower temporal resolution than those of the same age, but without cognitive defects. Considering the utility of these tests in identifying cognitive problems, we propose that since the GIN test seems to be less influenced by intervening factors, this test can therefore, be a useful tool for the early screening of elderly people with cognitive problems.

This study was aimed at identifying the factors of creative ability influencing problem-solving skills for University students majoring in nursing science. A descriptive study was conducted with a sample of 248 students enrolled in a 4-year undergraduate academic program for nursing in one University located in an urban area of Korea. This study used: (a) 25 items of Process Behavior Survey, and (b) 35 items of the Integrative Creativity Scale. The data were collected from Nov. 8th toward Nov. 26th, 2010; the research was conducted through voluntary participation after an explanation about the research. The data were also analyzed with SPSS 18.0 program, using Pearson correlation and stepwise multiple regression methods. Mean score of the level of problem-solving process was 3.62(${\pm}.448$). Problem-solving process was significantly related to creative ability(p<.01). Problem-solving process was significantly influenced by flexibility and elaboration in account for 42.4%. These results imply that in order to foster problem-solving ability, nursing professors need to develop nursing students' creative ability and its factors.

Previous researches on the effect of programming learning upon logical thinking ability have used a standardized test to measure logical thinking ability in the general and comprehensive aspect after programming learning. Considering that the areas of intelligence are separated from one another and work independently, the existing standardized tool to measure general and comprehensive logical thinking ability has a limitation in measuring a logical thinking ability required at specific areas. Thus this study extracted logical thinking and its sub-factors related to computer programming and suitable for the level of cognitive development through analyzing standardized test sheets at home and abroad, and developed logical thinking test I and II of the same form according to a development procedure model. The result of verifying the developed logical thinking tests proved that the two tests are logical thinking tests of the same form. The developed tests can be utilized in identifying the effect of programming learning upon logical thinking and its sub-factors.

The purpose of this study was to analyze the ability to control variables and the ways by which variables are controlled. First, the assessment criteria for evaluating the students' ability to control variables were developed for 8th grade students. Second, the ways variables are controlled were classified from student activity reports. These students' answers were categorized into six types (type A~ type F). Type A is defined as the group that excelled in recognizing the importance of controlling variables, eliminating unnecessary variables and identifying manipulated, dependent and controlled variables. Third, the scores of ability to control variables (CV score) and the classroom test of scientific reasoning (Lawson SRT) scores were measured. The results indicated that the CV score was highly correlated with Lawson SRT scores (r=.67, p<.01). Therefore, the assessment criteria developed in this study was used to evaluate the ability to control variables (CV score) and to measure the students' scientific reasoning.

This study investigated how elementary students with different spatial ability constructed spatial thinking process about on volcanoes and earthquakes with GeoMapApp-based materials. Students' spatial thinking process was analyzed in terms of spatial concept recognized, tools of spatial representation, and their spatial reasoning to construct topographic structure. The student group with high-scored spatial ability showed the spatial reasoning based on internal representation of building mental images through sectional division of horizontal distance, directly connected with spatial concept, or distorting spatial concept. The student group with low-scored spatial ability built the spatial reasoning directly connected with spatial concept instead of transforming into internal representation, and partially recognized spatial concept on either distance or depth. Based on the results, we argued identifying spatial concepts such as distance, height, or depth from the GeoMapApp data would be funda- mental for the better spatial thinking.

The purpose of the convergence study is to provide basic data for improving job satisfaction of speech and language therapists by identifying the relationship between personal characteristics, empathy ability, and job satisfaction of speech and language therapists, especially between cognitive and emotional empathy ability and job satisfaction. The subjects of the study were 111 people of speech and language therapists working in Daegu and Gyeongbuk. For data analysis, t-test, ANOVA, and correlation analysis were performed using the SPSS/PC 21.0 statistical program according to the purpose of the study. As a result of the study, the relationship between empathy ability and job satisfaction was found to be high, and there was a high correlation between cognitive and emotional empathy ability, which is a sub-factor of empathy ability, and job satisfaction. Therefore, follow-up research is needed to identify the empathy and job satisfaction about nationwide speech and language therapists for implementing various education programs and improving empathy skills in the future.

Purpose : This study aimed to provide basic data for developing strategies to improve the nursing performance of nurses working in the intensive care unit by identifying the degree of their communication ability, job satisfaction, organization commitment, and nursing performance, and the relation between each of these variables in the intensive care unit by examining the factors affecting nursing performance. Methods : The participants comprised of 150 nurses working in the intensive care unit in two advanced general hospitals. Data were collected using structured questionnaires and analyzed using a t-test, ANOVA, the Scheffé test, Pearson's correlation coefficients, and multiple regression analysis using the SPSS/WIN 25.0 program. Results : Nursing performance of the participants was positively correlated with communication ability (r=.64, p<.001), job satisfaction (r=.26, p<.001), and organization commitment (r=.29, p<.001). Factors significantly influencing the participants' nursing performance included academic background (𝛽=.16, p=.032) and communication ability (𝛽=.50, p<.001). The explanatory power of these variables for nursing performance was recorded at 49.9% (F=19.04, p<.001). Conclusion : The use of various programs in the hospital and the development of effective communication ability with medical staff and other departments among nurses will help improve nursing performance, cooperation with other departments, and patient care.

Purpose: Mid-upper-arm circumference (MUAC) is considered an alternative screening method for obesity. The aims of this investigation were to examine the ability of MUAC to correctly identify children with elevated body mass index (BMI) and to determine the best MUAC cutoff point for identification of children with high BMI. Methods: Anthropometric measurements (height, weight, and MUAC) from a cross-sectional sample of 7,921 Pakistani children aged 5-14 years were analyzed. Pearson correlation coefficients between MUAC and other anthropometric measurements were calculated. Receiver operating characteristic curve analysis was used to determine the optimal MUAC cutoff point for identifying children with high BMI. Results: Among 7,921 children, the mean (${\pm}$standard deviation) age, BMI, and MUAC were 10.00 (${\pm}2.86years$), 16.16 (${\pm}2.66kg/m^2$), and 17.73 (${\pm}2.59cm$), respectively. The MUAC had a strong positive correlation with BMI. The optimal MUAC cutoff points indicating elevated BMI in boys ranged from 16.76 to 22.73, while the corresponding values in girls ranged from 16.38 to 20.57. Conclusion: MUAC may be used as a simple indicator of overweight/obesity in children, with reasonable accuracy in clinical settings.

Currently, there are some aptitude test systems for older drivers in Korea. However, there are no methods and systems to evaluate the real driving ability for older drivers based on filed driving test. This study was conducted to investigate the availability to use the driving course test used for driving license for identifying difference in driving ability of older and non-older drivers. For the research purpose, filed experiments were conducted using the real driving course test site and evaluation times used in the field. In particular, driving behavior data that obtained from the experiments for two driver groups, older and non-older drivers, were analyzed and compared. From several statistical analyses of driving ability and vision and cognitive ability, it was found that the currently used driving course test site and evaluation times were not appropriated to identify driving ability deficiency of older drivers. To solve the problem, this study developed five evaluation items to identify driving ability deficiency of older drivers using the currently used driving course test site. It was also found that the developed five evaluation items have statistically significant correlation with vision and cognitive ability.
