Purpose: Human body have biological rhythmic pattern in a day, which is affected by internal and external environmental factors. We investigated whether respiratory function was fluctuated according to the influence of time-of-day (around at 9 am, 1 pm, and 6 pm) in health subjects, using pulmonary function test (PFT). Methods: Eighteen healthy volunteers (8 men, mean ages; $22.4{\pm}1.6$, mean heights; $166.61{\pm}9.60$, mean weight; $59.3{\pm}10.3$) were recruited. Pulmonary function test (PFT) was measured at three time points in day, around 9 am, 1 pm, and 6 pm in calm research room with condition of under 55dB noise level, using a spirometer (Vmax 229, SensorMecis, USA). Forced vital capacity (FVC), forced expiratory volume at one second (FEV1), FVC/FEV1, and peak expiratory flow (PEF) were acquired. Results: In comparison of raw value of PFT among three time points, subjects showed generally better respiratory function at 9 am, than at other points, although no significance was found. In comparison of distribution of ranking for respiratory function in each individual, only PEF showed significant difference. In general, distributional ratio of subjects who showed best performance of respiratory function in a day was high. Conclusion: These findings showed that circadian rhythm by diurnal pattern was not detected on respiratory function throughout all day. But, best performance on respiratory function was observed mostly in the morning, although statistical significance did not exist.

Purpose: This study was to identify predictors of sexual function in gynecologic cancer patients. Methods: The participants were 154 patients treated at a university medical center in A city, Korea. The data collection was performed through a structured questionnaire from July to December, 2010. The instruments used in this study were Female Sexual Function Index (FSFI) perceived health status scale, Eastern Cooperative Oncology Group (ECOG) performance status, body image, and depression. Data were analyzed using descriptive statistics, Mann-Whitney test, Kruskal-Wallis test and stepwise multiple regression with the SPSS 18.0. Results: The mean score of perceived health status was 8.42 and sexual function was 8.42. The lowest score among sexual function was lubrication. The scores of sexual function was significantly different by age, job, marital status, period after diagnosis of cancer and diagnosis. There were significant correlations between sexual function, perceived health status, ECOG performance, body image and depression. In multiple regression analysis, predictors were identified as ECOG performance, age, diagnosis and period after diagnosis of cancer (Adj.$R^2$=.28). The most powerful predictor of female sexual function was ECOG performance (19.0%). Conclusion: The above findings indicate that it is necessary to develop a more effective and personalized sexual function improvement program for gynecologic cancer patient.

PURPOSE: This study examined the changes in the handgrip strength, dexterity, and hand function according to the presence or absence of gloves and types of gloves. METHODS: Seventy-six adults in their twenties (male: 24, female: 52, mean age 21.04 years) were the subjects of this study. The handgrip strength, dexterity, and hand function were evaluated with bare hands without gloves, poly gloves, and latex gloves. The handgrip strength was measured using a dynamometer, and three pinch strength tests were performed: tip pinch, lateral pinch, and three-jaw pinch. The hand dexterity was evaluated using the Minnesota manual dexterity test, and the hand function was evaluated using the Jabson-Taylor hand function test. RESULTS: There was no difference in the grip strength depending on whether the gloves were worn. The hand grip, dexterity, and hand function showed significant differences according to the type of glove. Regarding the handgrip, dexterity, and hand function, the latex glove had the best function, and the poly glove had the lowest function. CONCLUSION: There was a difference in dexterity among the hand functions but no difference in grip strength according to the type of glove. The results suggest that the use of latex gloves in daily life be recommended.

Objectives The aim of this study was to investigate the effects of Cannabis Fructus on exercise capacity and cognitive function in chronic hypoperfusion induced vascular dementia rat model. Methods Vascular dementia rat models were induced by chronic cerebral hypoperfusion through bilateral common carotid arteries occlusion (BCCAO). All rats were randomly divided into 4 groups: normal group; control group; CF I group (feeding Cannabis Fructus 100 mg/kg); CF II group (feeding Cannabis Fructus 300 mg/kg). In order to study the effects of oral administration of Cannabis Fructus on vascular dementia rat models, corner turn test, hole board test, radial arm maze test, passive avoidance test were taken and Acetylcholine (ACh) activity, Acetylcholinesterase (AChE) activity, serum of Vascular endothelial growth factor (VEGF) protein level were measured. Also histological findings of the liver, kidney, brain and the change of Tau immunoreactive neurons in hippocampus were observed. Results CF I and CF II showed significant improvement in corner turn test, hole board test, radial arm maze test, passive avoidance test, Acetylcholine (ACh) activity, Acetylcholinesterase (AChE) activity, the serum of Vascular endothelial growth factor (VEGF) protein level and the change of Tau immunoreactive neurons in hippocampus. CF I showed more significant effect than CF II in these tests. However in histological observations of the liver and kidney both CF I and CF II showed glomerular injury and hepatotoxicity. Conclusions These results suggest that Cannabis Fructus was helpful in improving exercise capacity and cognitive function on Chronic hypoperfusion induced Vascular Dementia rats. However Cannabis Fructus affects the liver and kidney, therefore suggest that this is an area for further study.

We introduction some properties for fuzzy power function of performance of a test. First we define fuzzy type I error and type II error for the probability of the two types of error. And we show that an fuzzy error probability of one kind can only be reduced at cost of increasing the other fuzzy error probability.

Objective: The purpose of this study is to ob serve effects of CPM(Continuous Passive Motion) on hand functional and upper-extremity muscular strength rehabilitation for stroke patients. Method: Objects of this study, three patients have the symptoms of hemiplegia due to stroke. These are acute patients, within a 18 months after treatment and correspond in Brunnstrom stage 4~6. This study used single subject (A-B) design for three patients with a stroke and the effect of CPM was measured using Jebsen-Taylor hand function test, Purdue Pegboard test, hand muscular strength test. They received CPM for 3 weeks, 2 per day, 30 minutes for each, total 30 times. Results: Two patients' results of fingertip grip test in hand strength measurements did not change. Results of Jebsen-Taylor hand function test, Purdue Pegboard test and other hand muscular strength test were improved. To validate statistical results nonparametric statistical method, Wilcoxon signed ranks test was performed. P-Values are greater than 0.05 so difference between be fore and after treatment is not statistically significant result. Conclusion: Despite of limitation of short program period and fewer participants, CPM which has been conducted for stroke patients showed the effect on improvement of hand function and muscle strength. This study shows that CPM which is mainly used to treate lower-extremity rehabilitation can be use to improve performance of hand function and strength for patients with stroke.
