  • The purpose of this study was to investigate the effects of clinical characteristics of chronic stroke patients on physiological cost index (PCI) during walking. Fourteen stroke patients participated in this study. To investigate the clinical characteristics, Fugl-Meyer score (FMS), gait velocity (GV), muscle strength of the knee extensor, modified Ashworth scale (MAS) of ankle plantar flexor, devices, and gait patterns during walking were measured and analyzed. The results were as follows: Firstly, use of devices and high MAS of the ankle plantar flexor significantly increased PCI. Secondly, PCI was significantly correlated with the FMS and MAS of the ankle plantar flexor. In conclusion, inhibition of spasticity of the ankle plantar flexor is considered to reduce PCI during walking for chronic stroke patients.

  • A tactile stimulator array using stacked PZT is fabricated and evaluated in this paper. The purpose of this research is the development of a tactile stimulator to represent the obstacle information for the visually disabled. As a first step of this research, we investigate the physiological characteristics of tactile stimuli and design a tactile stimulator based on the investigated results. Also we evaluated a fabricated tactile stimulator. The prototype of tactile stimulator which has 2x2 tactor elements with 3mm spacing is fabricated using stacked PZT actuator. In order to evaluate the characteristics of this tactile stimulator, physiological experiments are carried out. In the experiment, the threshold of tactile stimulus intensity within a frequency range of 5-500Hz and at various stimulus amplitudes are investigated. According to the obtained experimental result, the input signal of tactile stimulator for the transfer of obstacle information is determined. Also physiological experiments of multi-stimuli recognition such as shift and rotation are carried out.

  • Steady and physiological flows of a Newtonian fluid and blood in the bifurcated arterial vessel are numerically simulated. Distributions of velocity, pressure and wall shear stress in the bifurcated arterial vessel are calculated to investigate the differences between steady and physiological flows. For the given Reynolds number physiological flow characteristics of a Newtonian fluid and blood in the bifurcated arterial vessel are quite different from those of steady flows. No flow separation or flow reversal in the bifurcated region in the downstream after stenosis appears during the acceleration phase. Also, no recirculation region is seen for steady flows. However, during the deceleration phase the flow began to exhibit flow reversal, which is eventually extended to the entire wall region.

  • Objectives: The purpose of this study was to assess the characteristics of body weight perception and physiological index in young adult women. Methods: Subjects were 283 Korea women. Data was from the 2005 Korean National Health and Survey. Three groups-low normal and overweight-were based on Body mass index(BMI). General characteristics, health status perception, weight control behavior and physiological index such as BMI, total cholesterol, high-density cholesterol (HDL), low-density cholesterol (LDL), triglyceride, systolic and diastolic blood pressure, and waist circumference were compared. Data were analyzed by t-test, $x^2$-test and ANOVA using SPSS program. Results: Of the normal weight group, 28.7% of subjects perceived themselves as overweight. Of the low weight group, 30.3% regarded their weight as normal weight. Of the overweight subjects, weight control was attempted by exercise (50.1%) and food reduction (77.1%). Significant group-related differences were evident in HDL, LDL, triglyceride, systolic blood pressure and waist circumference among three groups. Conclusions: Perception and attitude regarding body weight can be inaccurate. A weight control program should consider the relation of physiological index and weight based on BMI.

  • Background: Somatic cell nuclear transfer (SCNT) is a prominent technology that can preserve superior genetic traits of animals and expand the population in a short time. Hematological characters and endocrine profiles are important elements that demonstrate the stability of the physiological state of cloned animals. To date, several studies regarding cloned camels with superior genes have been conducted. However, detailed hemato-physiological assessments to prove that cloned camels are physiologically normal are limited. In this study, We evaluated the hemato-physiological characteristics of cloned male and female dromedary camels (Camelus dromedaries). Methods: Therefore, we analyzed variations in hematological characteristics and endocrine profiles between cloned and non-cloned age-matched male and female dromedary camels (Camelus dromedaries). Two groups each of male and female cloned and non-cloned camels were monitored to investigate the differences in hemato-physiological characteristics. Results: All the animals were evaluated by performing complete blood count (CBC), serum chemistry, and endocrinological tests. We found no significant difference between the cloned and non-cloned camels. Furthermore, the blood chemistry and endocrine profiles in male and female camels before maturity were similar. Conclusions: These results suggest that cloned and non-cloned camels have similar hematological characteristics and endocrine parameters.

  • Purpose: This study was conducted to determine factors affecting workers' physiological somatic complain using the Job Stress Model proposed by the National Institute for Occupational Safety and Health (NIOSH). Method: Data were collected from the 1st to the 30th of December 1999. The subjects were 2.123 workers employed at 155 work sites. Collected date were analyzed through SAS/PC program. Result: According to individual characteristics, younger and women groups showed significantly higher physiological somatic complaint than elder men groups. By work condition, groups with higher physiological somatic complaint included workers of irregular shift work. Dark lighting, improper temperature in winter, improper ventilation, inappropriate humidity, unpleasant work environment and crowded work place were significantly related with physiological somatic complaint. By work-related factor, physiological somatic complaint was high in those with higher variance in work load, quantitative work load, role conflict, job burden, role ambiguity and future ambiguity. On the other hand, physiological somatic complaint was low in those with little underutilization of ability. As for the relationships between physiological somatic complaint and non-work related factors, physiological somatic complaint was high in workers who had a side job, were bringing up infants alone, cleaned the house alone, cared for the elderly and disabled persons, were studying, were volunteering at another organization, and were spending 5-10 hours in religious activities per week. Physiological somatic complain was in significantly negative correlations with overall social support, supervisory support and family support, but in significantly positive correlations with co-worker support. Conclusion: The main predictors of physiological somatic complain were gender, shift work pattern, overtime work, ventilation, role ambiguity, role conflict, future ambiguity, job control, variance in work load, overall social support, worker with side job, worker who cleans the house alone, worker who is studying. These predictors explained 19.10% of the total variance of physiological somatic complain.

  • Subject : The physiological characteristic of Eight Extra Meridians. Objective : This study research physiological characteristic of Eight Extra Meridians that differentiate from the physiological characteristic of Twelve Regular Meridians. Method : First, we researched the meaning of "There are Eight Extra Meridians and they don't be arrested by Twelve Regular Meridians" in Nanjing 27Nan compared with the contents of regular Meridians circulation in Huangdineijing. Second, we studied on the origin of Eight Extra Meridians and researched their route. Third, from these researches we drew some physiological characteristics of Eight Extra Meridians. Conclusion : In Huangdineijing, the regular Meridians circulation include the route of Governor Meridian, Conception Meridian, and Heel Meridian. So the sentence in Nanjing 27Nan is contradictory to the contents of Huangdineijing. The origin of Eight Extra Meridians could be found in Huangdineijing. The collateral Meridians of the Uterus and Epiglottis Meridian are specifically formulated to supplying for the Uterus or Epiglottis. Eight Extra Meridians have third qualities of Meridian, collateral Meridian, and the solid viscera keep the Essence Gi, so named 'Extra'. And they have an intimate association with Extraordinary Organs. They place at the middle axis of human body, thus do higher physiological function that control and regulate the function of Twelve Regular Meridians and Five Viscera & six Bowels for adaptation to the environment.

  • This paper documents a study of the physiology of the lung. The aim of this paper is to better comprehend the physiological function of lung. To this end, the relationship between the physiological function of the lung and the characteristics of the 'Keum Un Qi Hua'(金運氣化), and the functional changes of the lung and its surrounding physiological systems have been studied in their relationship to the concept of the organism as a whole. The results of this study are as follows; The function of the lung is comprehended as corresponding to the 'Keum Un Qi Hua'. In visceral phenomenon, the lung has specific relations with the large intestine(大腸), nase(鼻), skin and hair(皮毛), sweat gland(汗孔), nasal mucus(涕), spirit(氣魄), grief and melancholy(憂 悲), the lung channel of hand-taiyin(手太陰肺經), the large intestine channel of hand-yangming(手陽明大腸經). This is called ‘the physiological systems of the lung’, and because these mutual relations reflect the functional changes of the lung, it is applied as the elementary knowledge to diagnose and treat the lung. For instance, a deficiency of the 'Qi‘ of the lung brings on an unconsolidated defending energy whose manifestations are sweating spontaneously as well as being susceptible to the common cold due to a diability in fighting against external pathogenic factors. Invasion of the lung by external pathogenic factors blocks the movement of the 'Qi' of the lung, which results in nasal obstraction. watery nasal discharge and a hyposmia. So the physiological functions and pathological changes of the lung can be determined by observing ’the physiological systems of the lung‘ based on the precepts of oriental medicine. As a result, the function of the lung is to be understood based on the characteristics of the 'Keum Un Qi Hua'. Furthermore we can know that the physiological systems of the lung mirrors the functional changes of the lung.
