Overall purposes of neuropsychological tests are summarized as follows: 1) Indentifying brain damage in individuals who have symptoms of uncertain etiology; 2) Assessing the extent and nature of deficits for forensic purposes and planning appropriate intervention; 3) Evaluating the effects of intervention or rehabilitation; 4) Examining the effects of various types of brain damage across different populations; and 5) Testing theoretical propositions about brain-behavior relationship. Of the neuropsychological tests, the Luria-Nebraska Neuropsychological Battery(LNNB) is easily transportable, relatively inexpensive, and performable by trained technician. The Korean version of LNNB is now being designed and will be used clinically in the near future. Localization and equipotential theories of brain function had been prevalent until Luria's theory of brain function. Brain, composed of three brain units in the theory, is the functional system in which each brain area has specific function and produce the function-related behavior. LNNB consists of 11 clinical scales, 5 summary scales, 8 localization scales, and 28 factor scales.

Orthostatic dizziness is feeling dizzy or lightheaded when standing up. Hemodynamic orthostatic dizziness can be caused by autonomic dysfunction such as orthostatic hypotension or postural tachycardia syndrome. The interpretation of the autonomic function test results in patients with orthostatic dizziness is crucial for diagnosing and managing the underlying condition. The head-up tilt and Valsalva tests are especially important for evaluating adrenergic function in patients with hemodynamic orthostatic dizziness. However, it is important to note that autonomic function tests do not cover the entire diagnostic process, since their findings need to be considered along with the detailed history and physical examination results of the patient because various differential diagnoses exist for orthostatic dizziness. Ensuring appropriate treatment by interpreting the autonomic function test results can help to determine the improvement of and prevents falls from orthostatic dizziness.

Hot-smoke testing in Australia has progressed to the stage where there is an Australian Standard for these tests. The purpose of such tests is twofold: firstly they can validate computer modeling predictions for smoke movement, and secondly they can demonstrate that the smoke control systems and associated fire safety systems function satisfactorily. Hot-smoke tests were carried out in March 1997 at two of Sydney's underground railway stations, namely St James and Museum. The purpose of the tests was to demonstrate that the smoke control systems performed their functions as intended. Tests were carried out in the concourses and on the platforms, and trains ran during the tests so that the effect of moving trains on smoke movement could be observed. A total of five tests were carried out and video recordings were taken of each. This is the first time that hot-smoke tests have been carried out in an underground station with trains running. The paper discusses some of the interesting observations and the problems identified by the tests.

In this paper, we consider the permutation tests for the multivariate data under the two-sample problem setting. We review some testing procedures, which are parametric and nonparametric and compare them with the permutation ones. Then we consider to try to apply the permutation tests to the multivariate data having the continuous and discrete components together by choosing some suitable combining function through the partial testing. Finally we discuss more aspects for the permutation tests as concluding remarks.

The actual power performance of historical structural change tests are compared under various alternatives. The tests of interest are F, CUSUM, MOSUM, Moving Estimates and empirical distribution function tests with both recursive and ordinary least-squares residuals. Our comparison of the structural tests involves limiting distributions under the hypothesis, the ability to detect the alternative hypotheses under one or double structural change, and smooth change in parameters. Even though no version is uniformly superior to the other, the knowledge about the properties of those tests and connections between these tests can be used in practical structural change tests and in further research on other change tests.

본 연구는 생물경제학(bioeconomics)분석에 있어서 중요한 위치를 차지하는 생물학적 성장모델에 대한 계량적 접근을 시도하였다. 세계적으로 어류에 관한 생물학적 성장모델은 여러 연구자들에 의해 추정된 바 있으나, 갑각류나 패류와 관련된 적정 성장함수의 추정은 어류에 비해 크게 연구되어 있지 않은 실정이다. 이에 몇몇 연구자들에 의해 사용된 공통된 성장함수들(Linear, Log reciprocal, Double log, Polynomial, Linear with Interactions)을 생산방식과 지역별 환경요인을 감안하여 한국 참가리비(Patinopecten yessoensis)의 성장을 추정하는 데 응용해 보았으며, 가장 적절한 모델은 계량적 분석을 통하여 도출하였다. 분석결과 Log reciprocal 형태의 성장함수가 참가리비류에 가장 적합한 모델로 선정되었으며, 본 결과는 경영자의 최적 생산시기를 결정하는 데 이용되는 생물경제학 모델에 유용하게 응용될 수 있을 것으로 사료된다.

The purpose of this study was to investigate effect of robot-assisted hand rehabilitation(Amadeo(R)) on hand motor function in chronic stroke patients. This study used a single-subject experimental design with multiple baselines across individuals. Three chronic stroke survivors with mild to sever motor impairment took part in study. Each participants had 2 weeks interval of starting intervention. Participants received robot-assisted therapy(45min/session. 3session/wk for 6wks). Finger active range of motion(AROM) was assessed by Range of Assessment program in Amadeo(R), and test-retest reliability was verified using Pearson correlation analysis. To investigate effect of Amadeo(R), finger AROM was measured immediately after each sessions and Fugl-Meyer Assessment of Upper extremity, Motor Activity Log, Nine hole peg board test and Jebsen-Taylor hand motor function test were assessed at pre-post intervention. Results were analyzed by visual analysis and comparison of pre-post tests. The test-retest reliability of Range of Assessment was good(r=.99). After robot-assisted therapy, finger AROM of participant 1, 2, and 3 was respectively improved by 18%, 3.6%, and 6% each. Hand motor function of participant 1, 3 was improved on all four tests, but not effect in participant 2. Robot-assisted hand rehabilitation could improve finger AROM and effect on hand motor function in chronic stroke patients.

Objectives: There are some controversies over the safety of herbal medication in relation to liver function. This report, therefore, aimed to analyze the safety issue of herbal medications by scrutinizing the liver function tests (LFT) results of 82 psoriasis patients on herbal medications for 3 months at an oriental medical clinic. Methods: We tested psoriasis patients' liver function periodically with Reflotron Plus of Roche during the herbal medication. Then we statistically analyzed the LFT results to see if there was any negative change. Results: Statistical analysis on the LFT results of 82 psoriasis patients showed no meaningful change caused by herbal medication over 3 months. Conclusions: From this result we conclude that herbal medication for 3 months does no harm to patients' liver function.

Purpose: The purpose of the study was to assess the effects of proprioceptive neuromuscular facilitation (PNF) training and respiratory muscle endurance training on pulmonary function and activity in chronic stroke patients. Methods: The participants were 25 chronic stroke patients. They were assigned to two groups: a PNF and respiratory muscle training group (experimental group; n = 12) and a conservative training group (control group; n = 13). The experimental group completed 50 minutes (30 minutes of conventional physical therapy, 10 minutes of PNF training, and 10 minutes of respiratory muscle endurance training). The control group also completed 50 minutes (30 minutes of conventional physical therapy and 20 minutes on a full-body workout machine). Pulmonary function and activity were measured before and after the intervention, using Cosmed to analyze pulmonary function and 6MWT as clinical evaluation indicators. Results: Both groups showed significant within-group differences on all tests before and after the intervention; the experimental group showed greater improvement on all tests. Conclusion: The findings confirm that PNF training and respiratory muscle endurance training have a positive effect on pulmonary function and activity index in chronic stroke patients.
