  • The purpose of this study was to identify differences in cognitive function according to the presence or absence of apraxia and the tasks most relevant to the cognitive function among the various types of tasks in the apraxia test. The subjects were 42 community residents who participated in a cognitive rehabilitation program related to dementia in a Chungbuk area. MMSE-K and BCoS(Birmingham Cognitive Screen) apraxia test were administered to all subjects. The apraxia test includes three types of tasks, gesture production tasks that make meaningful movements according to verbal instructions, gesture recognition tasks that display behavior after make sense of meanings, and meaningless imitation task. Apraxia group(n=30, MMSE-K mean score: 25) showed lower cognitive function than group without apraxia(n=12, MMSE-K mean score: 28). All tasks in the apraxia test showed a significant correlation with cognitive function, but the meaningless imitation task had a negligible correlation. The apraxia test is a good way to assess cognitive function, and it may be more effective to use meaningful behavior to replace cognitive testing.

  • The purpose of this study was to examine the feasibility and validity of the Application of Cognitive Function Scale as developed by Lidz and Jepsen (1997). Data were collected from 4 to 5-years-old children. The analysis for item adequacy indicated that the passing rate increases according to age. Futhermore the analysis for test adequacy indicated that internal consistency reliability was .85 in the pre-test and .80 of post-test in terms of the cognitive function scale, and .90 of pre-test and .93 in the post-test in relation to the behavior observation scale. In conclusion, our analysis of the ACFS shows sufficiently high scores in terms of both validity and reliability, so as to indicate that this test is an appropriate way to measure the cognitive function and non-intellective function of young Korean children.

  • Purpose: We investigated the effects of transcranial stimulation and task-oriented training on upper extremity and cognitive function in chronic stroke patients. Methods: A total of 30 patients were randomly divided into transcranial stimulation and task-oriented training groups (TT) and task-oriented training groups (TO). The TT group performed 30 min 5 times a week for 4 weeks in task-oriented training combined with transcranial direct current stimulation. The TO group performed 30 min 5 times a week for 4 weeks in task-oriented training. To measure upper extremity function, the Jebsen-Taylor Hand Function Test, Manual Function Test, and Cognitive Function Test were performed using the Stroop Test and the Trail Making Test. Results: There was a significant difference (P < 0.05) before and after training in both groups, and the TT group showed significant improvement in both groups. Conclusion: In this study, we confirmed transcranial stimulation and task-oriented training in upper extremity function and cognitive function in patients with chronic strokes.

  • Objective : The purpose of this study is to report that patient diagnosed as drug-induced liver injury treated with herbal and western medicine improve liver function test. Methods : We treated the patient diagnosed as drug-induced liver injury caused by antibiotics with Hepatotonics and Cheonggan-tang Gagam(淸肝湯加減). Then, We followed up the result of liver function test. After the result of liver function test improved, we diagnosed the patient with Korean medical methods, and evaluated the symptom of Cerebral infarction and liver function test treating the patient with Jihwangumja (地黃飮子). Result : After our treatment, Liver function test and symptoms of Cerebral infarction result improved. Conclusion : Use of Western medicine with herbal medicine can improved liver function test of drug-induced liver injury effectively and herbal medicine do not disturb the liver function.

  • The causes of liver disease in children and abnormal liver function test are more diverse than those in adult. Therefore, the first step to evaluate the liver disease is the understanding the liver disease and interpreting the appropriate liver function test in children. The characteristics of each test and various conditions which we encounter in outpatients settings will be discussed in this article, especially focused on elevation of aminotransferase level without identifiable causes.

  • Purpose: The purpose of this study was to identify the effects of an exercise program on frontal lobe cognitive function in seniors. Methods: The participants were 42 seniors using a health center in Seoul (experimental group) and 28 seniors using a facility for elders in Seoul (control group). The exercise program was carried out for 16 weeks from April to August 2007. The frontal lobe cognitive function, which includes short term memory, attention, immediate memory, delayed memory, verbal fluency and motor function, was measured by the Digit Span Forward test, Trail Making test, Immediate recall words test, Delayed recall words, Controlled oral word association test and Finger tapping test. The collected data were analyzed by Fisher's exact test, Chi-square, t-test, and ANCOVA using the SAS program. Results: The major findings of this study were as follows: Attention (p=.009), immediate memory (p=.005), delayed memory (p=.009), and verbal fluency (p=.004) improved after the exercise program. Conclusion: In this study, the exercise program was effective in improving frontal lobe cognitive function in elders. So it provides basic information for further nursing education on exercise programs which will be effective for prevention of early cognitive function decline in normally aging elders.

  • Objective : The purpose of this study was to investigate the reliability and concurrent validity of the computerized cognitive function test system (called CNFT) for evaluating the cognitive function and to provide its normative data. Methods : For this purpose, 140 normal adults participated in a investigation to provide the normative data of CNFT. 40 normal adults participated in an evaluating experiment to verify the reliability and validity. CNFT consists of attention, memory, sensori-motor coordination, and frontal lobe & higher cognitive function domains. Because CNFT is a computerized evaluation tool, all results and operations are processed consistently and automatically. Results : In the results, as the age of subjects increased, the average accuracy decreased and response time increased. Additionally, memory and frontal lobe & higher cognitive function was lower than other domains. Test-retest reliability of 2 weeks interval was highly correlated (r=.48~.85) and there is no significant difference between test and retest scores. CNFT was highly correlated with computerized neurocognitive function test (r=.67~.79; p<.05). Conclusion : Normative data of CNFT were obtained, and the guidelines for the interpretation were provided. A reliable and valid clinically applicable computerized cognitive function test was developed.
