Objectives : This study was to examine the effects of 3 types of BTS which were excluded talcum only or replaced talcum to Lonicera japonicae Flos or Kochiae Fructus on the DNCB-induced atopic dermatitis in mice. Methods : In this study, Balb/c mice were divided into five groups: normal, control, GBT(BTS except talcum), GBTG(GBT added Lonicera japonicae Flos), and GBTJ(GBT added Kochiae Fructus). And the effects on atopic dermatitis were evaluated by weight change, ear's thickness and weight, thickness of dorsal skin, severity scale of dorsal skin, histopathologic findings of dorsal skin by H&E and toluidine blue stain, proliferation of splenocyte and thymocyte in vitro, proliferation of splenocyte in vivo, IL-4, TNF-α, IgE in serum. Results : There were no significantly changes in body weight and effect of ear's weight in GBT, GBTG, and GBTJ group. The thickness of ear of GBT and GBTJ group showed significant decrease. And the thickness of dorsal skin of GBTJ group significantly decreased compared to the control, GBT, and GBTG group. All the treated groups significantly decreased in severity scale, histopathologically reduced epidermal thickness, and mast cell infiltration. In vitro, all the treated groups increased in the proliferation rates of splenocyte. However, in vivo study, it showed a falling tendency and GBT group significantly decreased compared to control, GBTG, and GBTJ group. In vitro study, GBTG group significantly decreased in the proliferation rates of thymocyte. There was no IgE contents chnage in GBT, GBTG, and GBTJ groups but IL-4 and TNF-α contents were significantly decreased. Conclusions : GBT, GBTG, and GBTJ are expected to improve symptoms of atopic dermatitis and further studies are needed for development of BTS's transformation.

This study, adopting the pretest-post test experimental study, is designed to find out how the functional electrical stimulation makes effect on the balance of a patient with spasticity of the ankle plantarflexor muscle caused by hemiplegic after stroke. The 46 subjects for this study were randomly sampled out of the patients who were hospitalized from September 1, 2003 to November 30, 2003 in H sanitarium in Yangpyung. The patients were with spasticity of the ankle plantarflexor muscle caused by hemiplegic after stroke and able to walk without supporting implements. The purpose of the study is firstly to analyze the change of ROM, FRTof a patient with spasticity of the ankle plantarflexor muscle when the functional electrical stimulation is applied and secondly to find out how the sex, age, height, weight, part of the diagnosis, duration of pain, experience of relapse and getting hurt from a fall of a patient make effect on the change. The experimental group for the study is divided into two to compare the differences of the effect. The exercising treatment only was performed for the conrtol group, and the functional electrical stimulation to the ankle dorsiflexor muscle as well as the exercising treatment was applied to the experimental group. The ROM test was performed to check the range of motion of the ankle with a double armed universal goniometer. The test was done 3 times to take an average. FRT were performed to check the balance. The statistical test was conducted using the SPSS 10.0/PC program by means of the following methods: χ2-test and t-test for testing homogeneity between the groups; paired t-test, independent sample t-test, F-test, and two-way ANOVA for analyzing the changes before and after the treatment. The levels of statistical significance of all the data were maintained at p<.05. According to the test, ROM has more decreased in experimental group than in control group when the functional electrical stimulation was applied only to the experimental group. However, the significant statistic difference was not shown (p=.059). FRT showed remarkable differences in the experimental group compared to the control group, showing the significant statistic difference (p=.000). On the one hand, the change of ROM, FRT related with the sex, age, height, weight, part of the diagnosis, and experience relapse was a meaningless minimum value. The change of ROM related to the duration of pain and the experience of falling down was also meaningless. However, FRT showed significant statistic difference (p<.05). According to the test above, the application of functional electrical stimulation to a patient with spasticity of the ankle dorsiflexor muscle caused by hemiplegic after stroke makes significant effect on the balance of a patient, but the result has nothing with the sex, age, height, weight, part of the diagnosis, duration of pain, experience of relapse and getting hurt from a fall of a patient. However, it is regarded to give contribution to the balance improvement of a patient. Therefore, this study expects to be a valuable clinical material for a patient with spasticity.

The purpose of this study was to compare GRF characteristics during walking wearing jogging and roller shoes. Twelve male middle school students (age: $15.0{\pm}0.0\;yrs$, height: $173.6{\pm}5.0\;cm$, weight: $587.6{\pm}89.3\;N$) who have no known musculoskeletal disorders were recruited as the subjects. Kinematic data from six S-VHS camcorders(Panasonic AG456, 60 fields/s) and GRF data from two force platform; (AMII OR6-5) were collected while subjects walked wearing roller and jogging shoes in random order at a speed of 1.1 m/s. An event sync unit with a bright LED light was used to synchronize the video and GRF recordings. GRF data were filtered using a 20 Hz low pass Butterworth. digital filter and further normalized to the subject's body weight. For each trial being analyzed, five critical instants and four phases were identified from the recording. Temporal parameters, GRFs, displacement of center of pressure (DCP), and loading and decay rates were determined for each trial. For each dependent variable, paired t-test was performed to test if significant difference existed between shoe conditions (p <.05). Vertical GRFs at heel contact increased and braking forces at the end of initial double limb stance reduced significantly when going from jogging shoe to roller shoe condition. Robbins and Waked (1997) reported that balance and vertical GRF are closely related It seems that the ankle and knee joints are locked in an awkward fashion at the heel contact to compensate for the imbalance. The DCP in the antero-posterior direction for the roller shoe condition was significantly less than the corresponding value for the jogging shoe condition. Because the subjects tried to keep their upper body weight in front of the hip to prevent falling backward, the DCP for the roller shoe condition was restricted The results indicate that walking with roller shoes had little effect on temporal parameters, and loading and decay rates. It seems that there are differences in GRF characteristics between roller shoe and jogging shoe conditions. The differences in GRF pattern may be caused primarily by the altered position of ankle, knee, and center of mass throughout the walking cycle. Future studies should examine muscle activation patterns and joint kinematics during walking with roller shoes.

현재 기존 동상방지층 설계법에 따르면, 동상방지층은 도로 노상토의 동상특성이 아닌 온도에 따른 동결깊이에 근거해 일률적으로 결정되어 포장설계의 부실 또는 과다설계 우려가 있다. 도로는 다양한 재료와 단면으로 구성된 구조물이기 때문에 환경성과 재료 물성 뿐만 아니라 포장체 각 층의 구조적 적정성 또는 지지력을 파악하는 것이 무엇보다 중요하다. 따라서 본 논문에서는 대형 냉동고내에 실내모형토조를 구성하여 포장하부구조재료(노상층, 쇄석골재층)의 시간에 따른 온도와 동상량 변화, 동결융해에 따른 지반의 지지력 변화를 통하여 포장하부구조체의 역학적 관계를 분석하였다.

Purpose: To find the correlation between ambient temperature change and the efficacy of acupuncture on the postmenopausal hot flash. Methods: 52 patients entered a randomized clinical trial which was to verify the efficacy of acupuncture on postmenopausal hot flash. Participants were treated with optimal/minimal acupuncture in the course of 13 weeks. 34 of 52 visited for the temperature-rising period(Group 1), while 18 of 52 for the temperature-falling period(Group 2), 100mm hot flash VAS and average temperature were taken 18 times from each person. Linear mixed effects model was used to find the correlation between temperature and hot flash VAS score(p-value<0.05). Group1/2, optimal/minimal acupuncture, age, age of menarche, height, weight, percent body fat, BMI, waist-hip ratio, past history of hysterectomy and HRT were also examined. Results: Period of treatment had influence on the hot flash VAS. As time went by, hot flash decreased(p<.0000). Participants who underwent minimal acupuncture showed higher hot flash VAS(p=0.0479) and as waist-hip ratio rose, hot flash increased(p<.0000). As the temperature rose, hot flash VAS score became lower(p=0.0143) and it was because 34 of 52 participants were treated for the temperature-rising period. Group 1/2 had no interrelation with hot flash(p=0.5741). Conclusion: Hot flash diminished as participants were treated with acupuncture, independently of whether the ambient temperature rises or falls.

PURPOSE: This study examined the effects of Interactive Metronome training on the plantar pressure and fall efficacy in chronic stroke patients. METHODS: Twenty-two hemiplegic patients were allocated randomly to an experimental group and control group. The experimental group received conventional physical therapy and emphasized weight-bearing interactive metronome training, whereas the control group received conventional physical therapy. The training was performed three times per week, 40 minutes per each session, for a total of seven weeks. The plantar pressure was assessed using the contact area and contact pressure, whereas the fall efficacy was assessed using the FES (Fall Efficacy Scale), ABC (Activities-specific Balance Confidence scale) and FOFQ (Fear of Falling Questionnaire). RESULTS: After training, a significant increase was observed in the paretic side of the contact area and the paretic and non-paretic side of contact pressure in both groups (p<.05). The between-group differences in the changes before and after training were statistically significant in the paretic side of the contact pressure (p<.05). After training, both the FES of the between-group and ABC of the experimental group were increased significantly (p<.05), but the between-group differences in the changes before and after training were not statistically significant in the FES, ABC, and FOFQ (p>.05). CONCLUSION: Interactive Metronome training is considered an effective treatment for improving the contact pressure of the paretic side in chronic stroke patients.

In this paper, COP (center of pressure) during quiet standing and squat-and-stand movement was analyzed to compare the postural control of young and elderly subjects with special interest in the elderly females who were reported to have higher fall rate than the elderly males. Subjects include the young subjects (10 males: $21.8{\pm}2.6yrs$, 10 females: $20.4{\pm}0.3yrs$) and the elderly subjects (8 males: $75.5{\pm}4yrs$, 8 females: $72.3{\pm}3.5yrs$). Analysis parameters were the mean of the distance between the instantaneous COP and the average COP (COP distance) and the mean of the COP movement velocity (COP velocity) in both AP (anterio-posterior) and ML (media-lateral) directions. During quiet standing, the COP distance in ML direction of elderly females was significantly greater than that of elderly males and the COP velocity of elderly females in both ML and AP direction were significantly greater than those of all the other groups. During squat and stand movement, the COP distance of elderly females was not significantly different with that of the elderly males. However, the COP velocity of elderly females was significantly greater than that of all the other groups. The large lateral weight shift (COP distance) of elderly females during quiet standing may explain their greater fall rate. However, this does not apply to squat-and stand movement. In contrast, COP velocity results show that the elderly females' COP is rapidly trembling compared to that of elderly males during both quiet standing and squat and-stand movement. This results suggest that rapid trembling or postural sway may reflect the reduced postural control ability and the risk of falling.
