If a controlled sensory stimulation is given to the specific receptors, a reflex movement and motor engrams is achieved by the principle of neurophysiology. Based on this theoretical background, we choose 80 healthy person(male 40,female 40) and compare chronaxie of before stimulation with after stimulation. Also we measured chronaxie with same method. Stimulation was applied to the muscle belly by tapping. The results are summarized as follows; 1. The mean value of rheobase measured from the proximal part of upper extremity is 3. 56mA for male, 4.04mA for female. 2. The mean value of rheobase measured from the lower extremity is 4.19mA for male, 4. 37mA for female, which is higher than that of upper extremity for both male and female. 3. The mean value of chronaxie from the proximal part of upper extremity is 0.91msec for male, 0.87 msec for female, which means male is higher than female, and the average is 0.82msec. 4. The mean value of chronaxie from the proximal part of lower extremity is 1.04msec for male, 1.14msec for female, which means female is higher than male. 5. The decrease of rheobase after stimulation is prominent at the triceps brachii for male, biceps brachii for female. 6. The decrease of rheobase after stimulation is prominent at the tibialis anterior for both male and female. 7. The decrease of chronaxie after stimulation is prominent for both male and female at the triceps brachii from upper extremity and at the tibialis anterior from lower extremity for both male and female.

The effect of a traditional fermented soy product, chongkukjang, on body weight gain and body composition were studied in high fat diet-induced obese rats. The rats were divided into 3 groups (n=11, male), and fed casein, raw chongkukjang or steamed chongkukjang as dietary protein sources for 4 weeks (n=5) or 8 weeks (n=6). Body weight gain was not significantly different among experimental groups. Raw chongkukjang group had higher total organ weight but had lower epididymal fat pad weight than other groups. This result is related with decreased body fat ratio. Food efficiency ratio (FER) was higher in control group for the first 4 weeks (p<0.001). But after 4 weeks, raw chongkukjang group had highest FER. From the above-mentioned results, it can be concluded that consumption of raw chongkukjang may be helpful in preventing metabolic syndrome caused by high fat diet by decreasing body fat ratio.

Low back pain is one of the primary maladies of morden society. Current studies indicate that approximately 80% of the population. It is widely accepted that 1 out of every 3 people have some back pain at given time. Whatever the theory, and whatever the diagnosis, one thing is obvious; a problem so widespread in our industrialized society must have common traits. Examination of the typical patient with lower back pain often reveals the reverse. The purpose of this study was to identify the differential evaluation method of low back pain syndrome. During the movement of nutation the sacrum rotates about an axis constituted by the axial ligament so that the tension developed in the sacrotuberous and sacrospinous as well as sacroiliac ligament. when nutation has pain in total flexion of spine, it is problem of sacroiliac ligment. But if when counter-nutation has pain in total flexion of spine, it is problem of lumber spine. If pain was that when pressing ischial tuberosity to anterior, it is problem of hip joint.

This study was intended to observe the relationship of pain alleviation between the group with needle electrode electrical stimulation applied on bach of head, lung, nasalis internae, shen-men, pharynx & larynx, and internal secretion which are the pants to regulate smoking and that, with no treatment of the kind among smokers and con-smokers with chronic low back pain. It also aimed to conduct a research of applying different treatment methods according to smoking, thus ultimately providing basic data needed by clinic therapists and to help achieve appropriate treatment effects considering the characteristics of each patient. The subject criteria were men who were in their 40's or 50's, smoking or non-smoking and came to the physical therapy of the hospital to cure the chronic low back pain which had lasted more than three months. The total 24 subjects were randomly divided into four groups according to smoking; the group of smokers with needle electrode electrical stimulation applied, that of smokers with no application of such treatment, that of non-smokers with the action of such treatment, and that of non-smokers with no application of such treatment Each group was measured in terms of four pain assessment methods of visual analogue scale(VAS), verbal rating scale(VRS), McGil pain questionnaire(MPQ), endorphin. And the results were as follows: 1. In terms of the effects of the needle electrode electrical stimulation in the auricular therapy on pain had by the smokers with low back pain, there was a statistical significance in VAS, VRS, and endorphin 1 between before and after the treatment. 2. In terms of the pain effects had by the smokers with low back pain when no needle electrode electrical stimulation in the auricular therapy was applied, there was a statistical significance in VRS and MPQ between before and after the treatment. 3. In terms of the effects of the needle electrode electrical stimulation in the auricular therapy on pain had by the non-smokers with low back pain, there was a statistical significance in VAS, VRS, and MPQ between before and after the treatment. In terms of the pain effects had by the non-smokers with low back pain when no needle electrode electrical stimulation in the auricular was applied, there was a statistical significance in VAS, VRS, and MPQ between before and after the treatment. 5. The smokers with low back pain were given the needle electrode electrical stimulation in the auricular therapy to see how it affected their pain. There was found pain reduction in number, but no statistical significance. 6. The subject suffering from low back pain were given the needle electrode electrical stimulation to see how it affected their pain according to smoking. There was found pain reduction in number, but no statistical significance. Based upon the results, it can be concluded that smokers with low back pain received the more effects of pain alleviation from the application of the needle electrode electrical stimulation in the auricular therapy compared to the rest of the groups who suffered from low back pain.

Recent studies have revealed that Nitric oxide(NO) was one of the demonstration for the physiological regulator, endothelial derived relaxing factor(EDRF) and that NO was produced by ultraviolet irradiation in human. Thus, the present author have carried out a experimental study on the change of hematological, histological value of ultraviolet irradiation in sprague-dawley rats. The subjects were divided into four groups of ten rats each selected at random. There were 4 groups: 1. no irradiation control; 2. ultraviolet $75mJ/cm^2$ irradiation group; 3. ultraviolet $150mJ/cm^2$ irradiation group; 4. ultraviolet $225mJ/cm^2$ group. After a irradiation, hematological and histological tests were performed to observe erythrocyte, hemoglobin, hematocrit, MCH, MCHC, MCV, $O_2$ saturation, pH, $PO_2,\;PCO_2$ value and to observe histological changes. In hematological tests, erythrocyte, hemoglobin, hematocrit significantly increased in $75mJ/cm^2$ than control group and more $150mJ/cm^2$ ultraviolet irradiation group respectively. Also In blood gas tests, $PO_2$ significantly increased in $75mJ/cm^2$ and more $150mJ/cm^2$ group than control group. Whereas $PCO_2$ significantly decreased in $75mJ/cm^2$ and more $150mJ/cm^2$ group than control group (Duncan-Tukey test, P<0.05). In histological tests, control and $75mJ/cm^2$ group unchanged, but more $150mJ/cm^2$ group changed that it was cytolysis, cytotoxic effect, acanthosis, proliferation of keratinocyte, appearance of amorphous cell and pyknotic nucleus, production of sunburn cell. In conclusion, the present author results support the importance of the relation between NO effect and hematological, histological value by ultraviolet B irradiation.

One of the noticeable linguistic characteristics that the patients with apraxia had was that they segmentalized syllables and pronounced articulation longer than others. For this reason, their speech was slower than others on the whole. The subject of this study included 5 patients with apraxia as well as aphasia and 5 patients with aphasia and no apraxia, and the purpose of this study was to analyze the characteristics of segmental sound and rhythm of the patients with apraxia by means of suggesting a stop sound in a form of description and interrogation. Experiment data of this study were limited to one-syllable words and two-syllable words and this study attempted to examine an ability of realizing the rhythm of apraxia by providing them with a stop sound in a form of description and interrogation as well as in a form of ‘CV’ formula and ‘VCV’ formula so as to find out the characteristics of the stop sound according to the phonetic environments. As a result, it has been demonstrated on the whole that the length of acoustic variable in apraxia was significantly longer than aphasia and normal group. Keywords : apraxia of speech (AOS), Aphasia, Stop sound, VOT(Voice Onset Time)
