The purpose of this study was to investigate the changes of kinetic and kinematic parameters in obstacle gaits after 12 weeks of an aquatic exercise program. Eight female elders walked in four different heights of obstacles(0, 2.5, 5.1, & 15.2cm) on their self-selected speed. The ROM of hip was significantly increased after the aquatic exercise program. Swing and Stance duration were decreased. The step length was significantly increased and the step width was decreased. After the exercise program the clearance between the right foot and the top of obstacle(except 15.2cm) increased and the crossing speed was increased. The braking force, propulsive force, braking impulse, and propulsive impulse were significantly changed after the aquatic exercise program. The 12 weeks of the aquatic exercise program resulted in lower body strength and balance gains in female elders. The improvements were associated with changes in kinetic and kinematic parameters leading to an obstacle-crossing speed and a safer lower-limb control. The aquatic exercise program is suggested as an effective intervention to promote gait ability and prevent fall-related to the injuries.
Falls associated with tripping over an obstacle can be dangerous, yet little is known about the strategies used for stepping over obstacles in older Parkinson disease. The purpose of this study was to investigate the lower extremity muscle activity on the obstacle gait according to obstacle height in older Parkinson diseases. The obstacle gait of 7 older Parkinson disease was examined during a 5.0 m approach to, and while stepping over, obstacles of 0, 25, 52, and 152mm. Seven pairs of surface electrodes(Noraxon MyoResearch, USA) were attached to the right-hand side of the body to monitor the adductor longus(AL), gluteus medius(GME), gluteus maximus(GMA), biceps femoris(BF), rectus femoris(RF), gastrocnemius(GA), tibialis anterior(TA). Electromyography data were filtered using a 10Hz to 350 Hz Butterworth band-pass digital filter and normalized to the maximum value in the analyzed phases. A one-way ANOVA for repeated measures was employed for selected electromyography variables to analyze the differences of the height of four obstacles. The results showed significant differences between 0.0mm and 25, 52, and 152mm obstacle height in TA and GA activities during the second phase(swing phase). But the more increase obstacle height, the more not increase the muscle activities. This means that the Parkinson disease stepping over obstacle inefficiency. To prevent and reduce the frequency of falls, elderly Parkinson disease maintained and improved their balance, muscular strength, neuromuscular control and mobility.
This survey was conducted to investigate the relation of children's obesity index to their mothers' food habit during the October in 1995. The survey covered a total of 492 mothers whose children were in the fifth grade of elementary schools in Cheju City area. The results are summarized as follows: 1.The surveyed children's average WLI(Weight-Length Index) is 107.08. WLI shows that 16.1% of them are overweight, 16.1% obese and 49.8% ideally weighted. The mothers' average BMI(Body Mass Index) is 22.4. 21.8% of them are underweight and 69.4% normal. The children's obesity index is significantly correlated to their fathers', but not significant to their mothers'. 2.As to the food habit I (balance of nutrients intake), 58.4% of the mothers have 'excellent' or 'good' food habit and the mean score is 14.95 out of maximum possible score 24.0. Concerning to the food habit II (intake of sugar, fat and salt etc.), 87.4% of mothers have 'good' or 'fair' food habit and the mean score of is 13.34 out of maximum (possible score) 20.0. The mothers' food habit I and II, as a whole, have no significant effect on the children's obesity index, but in some items the significant relations are founded. The children's chesty index is significantly related to the intake of eggs (P<0.05) and pan-broiled or fried foods (P<0.05). The amount of mothers' food intake is significantly relevant to their obesity index (P<0.001), but not significantly to their children's. The food habit of mothers who have taken midnight snack almost every day are significantly related to their children's chesty index (P<0.05). The findings of the study emphasize the importance of the nutrition education to ensure health and better physical fitness for children and their mothers.
This study was taken to induce either anaesthesia or sedation for the purpose of applying to transport of live fish safely. 7 species of fish in addition to Tilapia mossambica were exposed to 250 ppm concentration of the anaesthetic quinaldine to determine the safe level for handling and transportation of these species. The results obtained are as follows ; 1. The time taken to lose balance increased with a decrease on the concentration of the anaesthetic. 2. Anaesthetization must be carried out under temperature lower or higher rather than optimum temperature. 3. The longer the length of the fish, the longer the anaesthetization time and recovery time of fish. 4. Coefficient of recovery period and body length is 0.78. 5. At 10-15 min. after anaesthetization, the serum levels of glucose, ALP and SGOT were at peat. 6. LDH of the anaesthetized fish is much more increased than that of the unanaesthetized. 7. In the more 250 ppm treatment, the pyknosis of the brain and spleen tissue appeared.

PURPOSE: The purpose of this study was to investigate the effects of the 8.5seconds cut-off of the 8-foot up-and-go test as a predictor of falling and a good discriminator of fallers and non-fallers in women in their 60s to 80s. METHODS: The final subjects of this study were 98 elderly women from six senior centers of B metropolitan city. The 8-foot up-and-go test evaluated agility and dynamic balance. The chair-stand test measured the muscle strength for of the lower body. Ankle dorsiflexion and plantar flexion were measured to assess the ankle mobility of the subjects in this study. RESULTS: The below 8.5seconds group showed significantly low values in age and high values in chair-stand (times/30 s), plantar flexion ($^{\circ}$), and K-MMSE (score) compared to the over 8.5seconds group. This group was significantly faster compared to the over 8.5seconds group. In the below 8.5seconds group, only plantar flexion ($^{\circ}$) of all the items showed significantly higher values among those in their 60s compared to those in their 70s and 80s. CONCLUSION: The 8.5seconds cut-off on the 8-foot up-and-go test as a good discriminator and predictor of falling showed differences among fall risk factors (age, lower extremity strength, cognition, and ankle mobility) in women in their 60s to 80s without having regular exercise and a fall experience over the past ones year.
The purpose of this study was to extract the spiritual characteristic factors of the security martial arts qualitatively which are emphasized in guard situation. To get the purpose of this study, 216 people who are students majored in security service, security service professionals, specialists of practical and theoretical security martial arts were selected as participants for this study. The results of this study were as follows. There were divided 4 sub-factors and 20 detailed factors. The spiritual characteristics of the security martial arts were named psychological spirit which was consisted of concentration, self-confidence, self-management, flow, and self-esteem, ethical spirit which was consisted of sacrifice, justice, royalty, peace, and sense of duty, martial arts' spirit which was consisted of courtesy, toughness, defense, balance of mind and body, and bravery, and practical spirit which was consisted of responsibility, cooperation, modesty, determination, and professionalism.
This research was carried out to determine the effect of dietary calcium(Ca) levels(low : 0.29, medium : 0.65 and high : 1.07%) on the digestibility, excretion and retention of nitrogen(N) phosphorus (P) in pigs fed diets supplemented with phytase(750U/kg). Twelve growing-finishing pigs(average body weight: 35kg) were divided into 3 groups and these pigs were reared in metabolism cage. After 10 days adaptation period, N and P balance experiments were carried out for 4 days. The results were summarized as follows ; 1. The High-Ca group was lower than the others in digestibility of P(Low-Ca and Medium-Ca group). 2. The amount of daily excretion of urinary N were 19.6g in Low-Ca group and 16.7g in high-Ca group. The High-Ca group was the lowest(22.71%/d) in the total N excretion. 3. The High-Ca group was the highest and the Low-Ca group the lowest in fecal P excretion. The urinary P excretions per day were 1.90g in Low-Ca group and 0.04g in High-Ca group. The medium-Ca group showed the lowest total P excretion(4.57g/d). 4. The N retention of the High-Ca group(20.50g) was greater than that of the Low-Ca group and Medium-Ca(5.02)g was the highest and the Low-Ca groups(3.92g) was the lowest in the P retention. These results indicate that dietary Ca level was an important factor influencing N and P utilization in pigs.
Circadian rhythmicity (e.g. secretory pattern of hormones) plays an important role in the control of reproductive function. We hypothesized that the alteration of feeding pattern via meal time shift/restriction might disrupt circadian rhythms in energy balance, and induce changes in reproductive activities. To test this hypothesis, we employed simple animal model that not allowing $ad$$libitum$ feeding but daytime only feeding. The animals of $ad$$libitum$ feeding group (Control) have free access to food for 4 weeks. The day feeding (=reverse feeding, RF) animals (RF group) have restricted access to food during daytime (0900-1800) for 4 weeks. After completing the feeding schedules, body weights, testis and epididymis weights of animals from both group were not significantly different. However, the weights of seminal vesicle (control : RF group = $0.233{\pm}0.014g$ : $0.188{\pm}0.009g$, $p$<0.01) and prostate (control : RF group = $0.358{\pm}0.015g$ : $0.259{\pm}0.015g$, $p$<0.001) were significantly lower in RF group animals. The mRNA levels of pituitary common alpha subunit ($C{\alpha}$; control : RF group = $1.0{\pm}0.0699$ AU : $0.1923{\pm}0.0270$ AU, $p$<0.001) and $FSH{\beta}$ (control : RF group = $1.0{\pm}0.1489$ AU : $0.5237{\pm}0.1088$ AU, $p$<0.05) were significantly decreased in RF group. The mRNA levels of ACTH were not significantly different. We were unable to find any prominent difference in the microstructures of epididymis, and there were slight alterations in those of seminal vesicles after 4 weeks of reversed feeding when compared to control samples. The present study demonstrates that the shift and/or restriction of feeding time could alter the pituitary gonadotropin expression and the weights of seminal vesicle and prostate in rats. These data suggest the lowered gonadotropin inputs may decrease androgen secretion form testis, and consequently results in poor response of androgen-dependent tissues such as seminal vesicle and prostate.

Objectives : The purpose of this study is 1) to explore the general tendency of the herbs or herbal formula for acne treatment in clinical practice 2) and to provide a basis for explaining the principles of acne treatment in Korean Medicine in order to make patients understand more easily based on pharmacological mechanism by analyzing the herbs or herbal formula using for acne treatment in clinical practice. Methods : In the domestic databases (Oriental medicine Advanced Searching Integrated System-OASIS, Korean Traditional Knowledge Portal-KTKP, National Discovery for Science Leader-NDSL, Research Information Sharing Service-RISS), we selected among the papers published using search terms related to "acne". Reports related to sasang constitutional medicine were excluded and a total of 23 papers were finally selected. Results : 29 prescriptions were retrieved from 23 papers. Chungan-tang (淸顔湯) notified formulas ranked first by Cheongsangbangpung- tang (淸上防風湯), Hwangnyeonhaedok-tang (黃連解毒湯), Dangguijakyaksan (當歸芍藥散) and Bipachungpe-eum (枇杷淸肺飮). Commonly used herbs are Forsythiae Fructus (連翹), Scutellariae Radix (黃芩), Gardeniae Fructus (梔子), Ligustici Rhizoma (川芎), and Angelicae Gigantis Radix (當歸). In most patients with inflammatory lesions or excessive flushing, exterior-releasing medicinal (解表藥) and heat-clearing medicinal (淸熱藥) were mainly prescribed for acne treatment, while in patients with acne accompanied hyperkeratinization, Excess sebum secretion, Dysmenorrhea or indigestion, qi-tonifying medicinal (補氣藥) or blood-tonifying medicinal (補血藥) were mainly used. KAGS (Korean Acne Grading System) was the most commonly used method for acne severity assessment. Conclusions : These findings suggest that the herbs or herbal formula for acne treatment in Korean Medicine is prescribed differently according to the cause and symptoms of acne in a unique way for control the whole body balance. Also, our findings could provide a basis for explaining the principles of acne treatment in Korean Medicine in order to make patients understand more easily based on pharmacological mechanism in clinical practice.
The progress of environmental science and technology in the developed countries has been rapid in recent years. Particularly remarkable has been the advancement of various pollutant control measures, which have brought the pollution of inorganic factors such as air and water under control. In contrast, diversity of the ecosphere, of which man is a part, is being steadily impoverished and the biological community is getting unvaryingly uniform. These phenomena were brought about by the expansion of artificial environment such as new industrial complexes, transportation facilities and urban development. Man has constructed uniform and artificial environment, believing in the premise of confrontation with nature, to such a scale that the natural environment and biological community have lost their balance. This will increasingly endanger the soundness of the biotic environment of nature, which constitutes the potential foundation both for the survival environment of man as biological entity and for the development of human civilization. In order to guarantee the soundness of man's body, intelligence and sensitivity as wholesome gene pool on the earth and for the future of man, primarily important environmental education is the understanding of how man can everlasting exist in and with the survival environment. In view of this reality, it is vitally important to create ecologically diverse and well-balanced environment with living materials, i.e., vegetation in order to secure lasting survival environment for man. This task is urgently required in highly artificial environment where non-biological materials have forced the impoverishment of the biological community. Therefore, environmental education for the future should not be totally oriented to technology as that in the past nor it is limited to the medical aspect where well-being of human is the sole object of concern. That is to say, environmental education for the future should be one that provides knowledge that human can understand his place based on the ecological concept and thereby make him to have ethical consciousness that he can control his behavior within the reasonable level for ecological niche who he is located.
