In the field of prosthesis arm control, tile pattern classification of the EMG signal is a required basis process and also the estimation of force from col looted EMG data is another necessary duty. But unfortunately, what we've got is not real force but an EMG signal which contains the information of force. This is the reason why he estimate the force from the EMG data. In this paper, when we handle the EMG signal to estimate the force, spatial prewhitening process is applied from which the spatial correlation between the channels are removed. And after the orthogonal transformation, which is used in the force estimation process the transformed signal is inputed into the probabilistic model for pattern classification. To verify the different results of the multiple channels, SNR(signal to noire ratio) function is introduced.

Meridian collateral and meridian points have been the base of acupuncture and moxibustion therapy. Also the theory have composed the main portion of Oriental Medicine. But the mechanism and scientific background has not been completely eatablished, and the research on the objectification of diagnosis of meridian collateral and meridian points, and acupuncture & moxibustion therapy has been necessary nowadays. A new understanding of value of Oriental Medicine has been increasing, the scientific understanding of meridian collateral and meridian points should have been examined. The system of meridian collateral and meridian points was very interesting topics between the scientists in the world. Especially, the elucidation of function and mechanism of Qi(氣) was very important in the scientific theme of 21th century. But there has been many difficulties in the study of meridian collateral and meridian points, since the system of meridian collateral and meridian points has the complexed function and vague structure in the organism. As the one of index of meridian points, the electric current has been used. In this report, the volume of electric current on the skin around the meridian points was investigated. The results of investigation showed the meridian points have higher electric current volume than non-meridian points.

This paper relates the occidental constitutional theory to the oriental one, concluding their origins to be similar, and demonstrates a new method of constitutional diagnosis by O-Ring Measurement System Of Muscular Meridians and Laser Constitutional Diagnosis. It establishes Laser Constitutional Diagnosis(L.C.D) using laser beams according to the principles of acupuncture and Sa-Sang constitutional physiology under the effect of spatial morphological energy of geometric isomers. Finally, hypothetical theory of L.C.D. was experimented by the O-Ring Measurement Systems of Muscular Meridians(O-R MSMM). O-R MSMM has been specially devised to improve the manual O-Ring Test prevailing to distinguish energetic response by muscle tonicity. Statistically, it has been proved that the constitutional diagnosis with O-R MSMM was highly effective and objective in the clinical experiences.

Most construction disasters are analyzed to be human factors such as not complying with the safety regulations of construction sites, not using clothing and protective equipment, safety insensitivity, and the health of workers. In order to prevent such a construction disaster, the project site management needs to check the health of workers, but it is difficult to check the condition of workers every hour. Therefore, this paper proposed the design of digital safety-helmet that can automatically identify health conditions by checking workers $SpO_2$ and pulse rates, away from simple protective features.

기존의 안과 진단 및 치료 기기의 안구 고정장치는 진단 및 치료에 있어서 피검사자와 검사자에 사이에 충분한 협조가 되지 않을 경우 진단의 비효율성과 치료의 안정성등의 문제가 발생하고있다. 따라서 이러한 문제를 보완하기 위하여 SLO의 전면 세극등을 소형의 반사경으로 대치하고 표시등을 후면의 먼거리에 수직으로 배열시켜서 피검사자에게 적당한 높이의 고정등을 선택하게하여 수직방향의 안구 위치를 고정시키고 SLO(Scanning Laser Ophthalmoscope)의 좌우 회전기능으로 표적의 수평방향을 근절시킨 후에 검사자의 조작으로 원격조정되는 서보장치를 이용하여 다시 반사경을 전방향으로 미세하게 회전되게하여 정확한 위치로 안구를 이동시키게 하는 원격조정 표적 추적장치를 개발하였다. 이에 따라 피검사자는 거울에 비친 먼거리의 허상을 보게 되어 세극등을 이용한 근접주사방식의 단점인 안구의 축동, 폭주등으로 인한 환자의 눈의 피로를 최소화하면서 피검사자의 안구를 검사자가 원하는 위치로 고정시킬 수 있게 함으로써 임상실험에서 안과 진단의 정확성과 관리도를 높이고 치료의 효율성과 안전성을 증가시킬 수 있는 원격조정 추적장치로써의 성능을 확인하였다.

Major type of facial asymmetry results from facial deformity and needs surgical correction. To diagnose facial asymmetry and set a treatment plane for patients, setting a sagittal reference plane is crucial. The purpose of this study is comparison of measurements of sagittal soft tissue reference point to three different sagittal planes. The subjects are 25 of asymmetry patients (M:15, F:10) and 19 of normal people. There are differences in point Gnathion and Stomion. Most of measurement of sagittal reference points showed within 1 mm difference from sagittal reference plane. Deviation of point Pronasale in Sa1 plane revealed significant difference among 3 reference planes. The deviation of Gnathion was proportional to the deviation of Stomion in all 3 reference planes.

Objectives : Clozapine has been known to increase the possibility of developing cardio/cerebrovascular diseases, and the platelet activation has been deemed to be related to the occurrence of them. In author's previous study, we observed the increase of platelet activity with short-term clozapine administration. This study was conducted, as a follow-up study, to investigate the effect of clozapine on the platelet activity when administered continuously for long-term period of time of 1 year. Methods : The medical records of the patients with schizophrenia or schizoaffective disorder who were treated with clozapine for 1 year were retrospectively reviewed. The degree of platelet activation was assessed by measuring the mean platelet component. Results : Total of 24 patients were enrolled. 9 of them (37.5%) were male and 15 of them (62.5%) were female. In the Wilcoxon sign-ranks test, no significant change was observed between the mean platelet factor values at the beginning and at the end of one year. Conclusions : No significant changes of mean platelet activity were observed after continued administration of clozapine for 1 year. Considering the author's previous findings that observed a prominent decrease of mean platelet component after short-term clozapine administration, the result of this study suggests the possibility that the activity of the platelet may change depending on the duration of the clozapine administration.

The present study was undertaken to determine the endemicity of trematode infections in Yongyang County, Kyungpook Province, Korea. One hundred and seventy-seven out of 955 residents examined were found to be infected with one or more kinds of helminthes. The prevalence rate was 18.5%. Among them, 70 were found to be infected with Clenorchis sinensis, 74 with Meta-gonimus sp. and 2:l with both flukes. The eggs of Fasciolidae were demonstrated from two specimens. The prevalence rate of clonorchiasis in males was 12.6%, while that in females was 3.6% (p<0.05). The prevalence of metagonimiasis in males was 12.0% and was also significantly higher than 6.1% in females (p<0.05). The intensity of both infections was significantly heavier in males than in females. The prevalence of both nukes was higher in residents of oyer 30 years of age than in those below that age. No correlation was found between the intensity and the age group. Among eight species of the fresh-water fish collected at the Panbyon River, Zacco temmincki was found to be the most frequently and heavily infested with metacercariae of Metagonimus sp., and Gnathopogon asromaculatus alone was found to be infested with metacercariae of Clonorchis sinensis. The present results suggest that Yongyang area still remains endemic with Clonorchis sinensis and Metagonimus sp. infection.

The object of this study is to apply a chaotic signal analysis method to the EEG research, especially in the aspect of neuropsychiatry, and to get some inspection of the chaotic phenomena according to the brain sites and subjects. We have acquired 21 channel EEG data and one EOG according to the international 10-20 system and calculated the correlation dimension. The subject groups are schizophrenics, bipolar disorder, major depression and normal control. They were all awoke and eye-closed. We have found no distinctive features from our experiments except temporal regions have slightly higher correlation dimension. There is also no specific distinctions between groups. We conjecture that these results are mainly because the subjects were not well controlled. EEG dimension may change in accordance with to the age, sex, medication and the time data were selected to calculate. We have also considered some conditions for a better and more objective research of chaotic analysis to EEG research. Better conditioning and standardizing the calculation of correlation dimension is necessary for the application of the chaotic analysis to neuropsychiatry.
