This study investigates the effects of wear training on blood pressure and blood lipid profiles. For the purpose of this research, 'wear training' refers to the alternating stimulation of temperature while using specific clothing under controlled situations ($18.8{\pm}0.2^{\circ}C$, $38{\pm}3%RH$). The participants alternated between two different garments producing a $1.5^{\circ}C$ difference in the innerest microclimate temperature over a period of 4 weeks. The experiments in this study were conducted in a comfortable environment after sufficient rest. The results were as follows. The systolic blood pressure and mean arterial pressure were lower in the post test than in the pre test (p<.05). The atherogenic index (AI) was also reduced and the LDL-C/HDL-C ratio increased (p<.05) in the post test. These results demonstrated that wear training positively affected improvement in vascular stiffness.

Objectives : To investigate the role of Meridian flow on acupuncture effect, we observed the therapeutic effects of electroacupuncture (EA) after Meridian blocking with pressure in arthritic rats. Methods : To make reliable and local monoarthritis, $40{\;}{\mu}l$ complete Freund's adjuvant was injected into the tibio-tarsal joint. EA was applied on acupoint GB30 while 5 Pascal pressure was added to the middle of the Gall bladder Meridian around GB31 between acupoint GB30 and arthritic foci (ipsilateral meridian blocking: IB) or opposite part of IB (contralateral part blocking: CB). To observe the change of arthritis, extension and flexion pain scores and circumferential differences were evaluated once a week. Results : EA stimulation without blocking reduced arthritic pain significantly. IB abolished the acupuncture effects and there was no statistical difference with the arthritic control group, whereas the CB group still showed the therapeutic effects of acupuncture. Conclusions : This finding strongly supports that the Meridian blocking with local pressure reduced the therapeutic effect of EA.

Pressure pain thresholds are routinely used in orofacial pain research to evaluate the response of deep orofacial tissues to mechanical stimulation. Like other psychophysical measurements, however, this technique must stimulate cutaneous tissues before stimulating deeper tissues. This study aimed at evaluating the influence of the cutaneous hypoesthesia on the pressure pain threshold in 30 healthy volunteers. PPTs were determined with electric pressure algometry over masseter, temporalis anterior, sternocleidomastoid, and trapezius muscle before and after skin hypoesthesia. A local anesthetic cream and a control cream were applied following a placebo-controlled double-blind design and PPTs were reassessed. Two examiners measured PPTs two times on each muscles, randomly. And the EMG activity of all muscles were measured to evaluate the relationship with PPTs. The collected data were processed by SAS/STAT program. The obtained results were as follows : 1. There were a tendency to increase PPTs after than before cutaneous hypoesthesia, but, there were no significant difference statistically. 2. PPTs were consistently higher in anterior temporalis than in masseter muscle. 3. In all occasions, PPTs were higher in males than in females(p<0.001). 4. A statistically significant correlation was obtained from values of intra-examiners and inter-examiners in all measured muscles. 5. A significantly positive correlation was not found between PPT and functional EMG activity.

Background: The flexible flatfoot is characterized by a flattening of the foot arch due to excessive bodyweight. The use of shoe insoles or taping methods has been identified as effective in realigning the navicular or calcaneus bones and addressing supination in pronated feet. Objects: This study aimed to analyze the difference between the arch taping attachment method, introduced in a previous study, and a novel taping method designed to provide support to the inner aspect of the heel bone in cases of flexible flatfoot. Methods: A navicular drop test was performed to discriminate flexible flatfoot. To analyze the differences in pressure distribution during walking for each taping method, the subjects underwent testing in the barefoot state with no attachments. The procedure included a sequence of arch taping and heel taping. Subsequent analysis of pressure distribution during walking utilized the GaitRite^® system (GAITRite Gold, CIR Systems Inc.). Results: Arch taping and calcaneus taping significantly reduced the integrated pressure over time and peak pressure on the medial side of the midfoot for both feet compared to the barefoot state. Conclusion: The findings of this study suggest that supporting the inside of the heel through calcaneus taping, without direct stimulation to the longitudinal arch and navicular bone, is an effective intervention for flexible flatfoot.

The authors investigated the relationship between the response to the external stimulation and ability of verbal behavior in the patients with somatoform disorder who have pain. The subjects consisted of 34 patients(male 10, female 24) and 37 normal controls(male 19, female 18). Pressure pain thesholds were measured by algometer and alexithymia was assessed by Toronto Alexithymia Scale(TAS). Somatization Scale of SCL-90R and Parental Bonding Instrument were also used. It was shown that 82.4% of the patients had chronic somatic complaints. The mean values of TAS, degree of somatic symptoms and pressure pain thresholds were significantly higher in the patient group than in the normal controls. 44.1% of the patients was considered alexithymia group and there was no correlation between scores of alexithymia and value of pressure pain thresholds. In conclusion, the patients with somatoform disorder who had pain were dull in pain perception to external physical stimulation. This result suggested that their low perception of pain could be closely related with chronicity of illness. And the Poverty of verbal expression of inner emotion was suggested to be one of the factors affecting somatization and difficulty in psychotherapy.

In this paper, we give pressure stimulation into organic ultra thin films and detected the induced displacement current properties, and then manufacture a device under the accumulation condition. In processing of a device manufacture, we can see the process is good from the change of a surface pressure and transfer ratio of area per molecule of organic ultra thin films. The structure of manufactured device is MIM(Au/polyimide LB films/AU), the number of accumulated 19 layers. I-V characteristic of the device is measured from -5[V] to +5[V]. The maximum value of measured current is increased as the number of accumulated layers are decreased. The insulation of a thin film is better as the interval between electrodes is larger, and the insulation properties of a thin film is better as the distance between electrodes is larger.

The purpose of this study is to help understand the pressure pain threshold's comparison following time progress after IMS to the trigger point and recognize this methode' effect for treating these kind of myofascial pain syndrome in clinic. Resently, myofascial pain syndrome is a disease that keeps the highest rate of patients visiting the Department of Rehabilitation Medicine. and so one should understand the change of IMS'effect following time progress for patients to be dealt rightly in clinic. In addition, the theory and treatment of myofascial pain syndrome needs to be understood or to be dealt rightly for therapists to treat and to approach to the right moment in right mode for the patients with myofascial pain syndrome. Therefore, one should know where to stimulate and why one stimulate trigger point and what effect one obtain after IMS.

The characterization of organic Metal/Insulator/Metal(MIM) devices were investigated from LB films. The physicochemical properties of the LB films were by UV absorption spectrum and AFM. We give pressure stimulation into organic thin films and then manufacture a device under the accumulation condition that the state surface pressure is 2, 10, 30[mN/ml The stable images are probably due to a strong interaction between the monolayer film and glass substrate. We are unable to obtain molecule resolution in images of the films but did see a marked contrast between images of the bare substrate and those with the network structure film deposited onto it.

We give pressure stimulation into organic thin films and detect the induced displacement current, In processing of a device manufacture, we can see the process is good from the change of a surface pressure for organic thin films and transfer ratio of area per molecule. The structure of manufactured device is Au/organic thin films(Kapton-Polyimide)/Au and I-V properties of the device is measured from 0(V) to +5(V). The maximum value of measured current is increased as the number of accumulated layers are decreased. The resistance for the number of accumulated layers, the energy density for an input voltage show desired results.
