Objectives: The purpose of this study is to study the personality traits and cognitive characteristics of the Sasang constitution by comparing the Personality Test and Neuropsychological Test. Methods: A total of 121 subjects were analyzed with the results of a Two Step Questionnaire for the Sasang Constitution Diagnosis (TS-QSCD). Among them, the Personality Tests (SPQ, EPQ, TCI) and the Neuropsychological Tests (A-VLT, CPM, Stroop-CWIT, WCST) were processed and analyzed for Soyangin, Taeeumin, Soeumin. Results: 1. In the results of the SPQ, the Soyangin showed a significantly higher score than did the Taeeumin and Soeumin in Behavior, Emotionality, Cognition, as well as the Total Score. The SPQ-C score and SPQ-T were significantly higher for Soyangin, Soeumin and Taeeumin, in that order. 2. In the results of the EPQ, the Soyangin showed a significantly higher score than did the Taeeumin and Soeumin in Extraversion - introversion. Soeumin showed a significantly higher score than did the Soyangin and Taeeumin in Neuroticism. Soyangin also showed a significantly higher score than Taeeumin in Venturesomeness. 3. For the results of the TCI, the Soyangin showed a significantly lower score than did Taeeumin and Soeumin in Harm-Avoidance, but a significantly higher score in Persistence and Self-Directedness. Soyangin and Taeeumin showed a significantly higher score than did Soeumin for the total score of Self-Directedness+Cooperativeness. 4. The results of the Computerized Neuropsychological Tests (A-VLT, CPM, Stroop-CWIT, WCST) showed no significant differences between the Sasang constitution. Conclusions: The EPQ, TCI score showed significant differences between the Sasang constitution. But the Computerized Neuropsychological Tests developed to evaluate cognitive abilities did not show differences between the constitutional individuals and showed limitations as a research tool. Further studies are needed to devise a research method for ascertaining the cognitive behavioral characteristics of the Sasang constitution.

Computerized spirometer was developed in a form of proto type system. The system consisted of pneumotachometer, flow measurement unit, fan ventilator unit, and software program. Patient's respiratory flow signal was first converted to corresponding pressure drop signal by a screen type pneumotachometer, sensed by a differential pressure transducer, amplified and low pass filtered, and digitized at a rate of 100 Hz, then fed into a PC thru RS-232C serial port. Customized application software controls data acquisition followed by computation of test parameters. The fan ventilator unit dries and eliminates microorganism in the pneumotachometer after each test. The system performs conventional spirometic tests and manages the test results in a database for retrograde research. The proto type system was fully developed and the commercialized system is currently being built up.

Purpose: The aim of this study was to evaluate the effects of a computerized cognitive training on older adults affected by mild cognitive impairment (MCI) in terms of cognitive function, depression, self-esteem, and activities of daily living (ADL). Methods: This study used a non-equivalent control group non-synchronized design. A total of 53 older adults who reside in long-term care facilities were recruited, 26 subjects for an experimental group and 27 subjects for a control group. A computerized cognitive training was performed for 20~40 minutes/day, three days/week for ten weeks. Data were analyzed using SPSS/WIN 21.0 with $x^2$ test, Fisher's exact test, and t-test. Results: Scores of MMSE (t=3.30, p=.002), depression (t=-2.15, p=.036), and self-esteem (t=2.76, p=.008) were significantly better in the experimental group than the control group. However, the difference in ADL (t=-1.01, p=.316) was not significant between the two groups. Conclusion: These findings suggest that the computerized cognitive training can be used as an effective nursing intervention to improve cognitive function and self-esteem and lower depression among older adults with MCI.

Objectives: This study was conducted in order to develop and obtain the nonnative data of the computerized Comprehensive Attention Test(CAT) in Korean children and adolescents. It also aimed to evaluate the reliability and validity of the CAT. Methods: We developed the computerized CAT which includes the selective attention task, the sustained attention to response task, the flanker task, the divided attention task, and the spatial working memory task. We investigated the test-retest reliability and the construction validity of this computerized version by using the data from 21 children, and gathered the nonnative data of 9l2 subjects, aged 4 to 15 years, dwelling in the Metropolitan Seoul area in 2008. Results: No statistical differences between means of the tests and retests of the CAT were observed. The mean of the correlation coefficient of the test-retest scores was 0.715. The results from the factor analyses explained 51.7% of the cumulative variance. In addition, the nonnative data for all of the CAT subtests were obtained. Conclusion: The computerized CAT can be used as a reliable and valid tool in both clinical and research settings for Korean children and adolescents with or without neuropsychiatric conditions such as attention deficit.

Objective: This study is to examine the validity and reliability of Computerized Neurocognitive Function Test among normal children in elementary school. Methods: K-ABC, K-PIC, and Computerized Neurocognitive Function Test were performed to the 120 body of normal children(10 of each male and female) from June, 2002 to January, 2003. Those children had over the average of intelligence and passed the rule out criteria. To verify test-retest reliability for those 30 children who were randomly selected, Computerized Neurocognitive Function Test was carried out again 4 weeks later. Results: As a results of correlation analysis for validity test, four of continues performance tests matched with those on adults. In the memory tests, results presented the same as previous research with a difference between forward test and backward test in short-term memory. In higher cognitive function tests, tests were consist of those with different purpose respectively. After performing factor analysis on 43 variables out of 12 tests, 10 factors were raised and the total percent of variance was 75.5%. The reasons were such as: 'sustained attention, information processing speed, vigilance, verbal learning, allocation of attention and concept formation, flexibility, concept formation, visual learning, short-term memory, and selective attention' in order. In correlation with K-ABC to prepare explanatory criteria, selectively significant correlation(p<.0.5-001) was found in subscale of K-ABC. In the test-retest reliability test, the results reflecting practice effect were found and prominent especially in higher cognitive function tests. However, split-half reliability(r=0.548-0.7726, p<.05) and internal consistency(0.628-0.878, p<.05) of each examined group were significantly high. Conclusion: The performance of Computerized Neurocognitive Function Test in normal children represented differ developmental character than that in adult. And basal information for preparing the explanatory criteria could be acquired by searching for the relation with standardized intelligence test which contains neuropsycological background.
