Sarcoidosis is a multisystem granulomatous disease of unknown cause, characterized by enhanced cellular immune process at the sites of involvement. Three Cases of sarcoidosis involving vilateral hilar lymph nodes, skin and lungs were presented. Each case was confirmed by characteristic non-caseating granuloma in biopsied thoracic lymph nodes and skin. They had abonormal pulmonary function test, elevated serum angiotensin converting enzyme, hilar and mediastinal lymphadenopathy and compatible clinincal features of sarcoidosis.

The purpose of this study was analyze children's Physical Fitness and basic rate by observing the change in the heart rate of the 1230 children of five of six years of age. Following conclusions were obtained The muscular strength was relatively low according to places. And the muscular strength of boys was higher than that of girls. The flexibility of girls was higher than that of boys according to places and sexes. The muscular endurance, power, balance and agility of boys were higher than those of girls according to places and sexes. Thus the development of physical fitness was improved with their ages, the physical fitness for physique seemed rather low. So the programs of physical plays for children's physical fitness ought to be developed and physical play showed to be done at kindergarten school.

Immunocytochemistry at the electron microscopic level has allowed the distribution of antigens in the cellualr system to be examined. In transmisson immunoelectron microscopy, two different approaches have been used, i, e., preembedding or post-embedding methods, depending on whether labeling is carried out before or after the embedding process, respectively. The good preservation and expression of the antigenic molecules in the tissues are most important in the ultrastructural immunocytochemistry. A low temperature resin, Lowicryl K4M for postembedding method is frequently used in many immunoelectron microscopic laboratories. Periodate-lysine-paraformaldehyde(PLP) fixed tessues are dehydrated and embedded at -20℃ in a hydrophilic resin, Lowicryl K4M. The resin is easy to section and a good embedding material for preservation of antigenicity in the tissues. Immunogold labelling technique marks localization of antigenic molecules in the subcellular level. In the scanning immunoelectron microscopy, a silver-enhancing technique can well express the antigenic immunogold partickes using smaller gold probes(15mm) in the standard scanning electron microscopy.

Objectives : To observe the effect of acupuncture treatment in chronic shoulder pain patients. Methods : 36 voluntary patients were randomly assigned to an acupuncture treatment group(E GrouP, n=18) and a control group(C GrouP, n=18). The E Group patients received acupuncture treatment on LI_(15), TE_(14), GB_(21) and Master Dong's acupuncture points, Shin-gwan and Gyun-joong, twice a week for four weeks. The C Group patients received no treatment. All patients in both groups were instructed to practise self exercise in their daily lives. Evaluations were made at baseline and after four weeks of study. The Constant Shoulder Assessment(CSA), Shoulder Pain and Disability Index(SPADI) and the patient's subjective pain was measured by Visual Analogue Scale(VAS). The obtained data was analyzed. Results '. The E Group showed significant(p<0.05) improvement in CSA, SPADI and VAS after four weeks of treatment. The C Group showed significant(p<0.05) improvement in CSA, but the change of SPADI and VAS was insignificant(P>0.05). CSA and SPADI of E Group significantly(p<0.05) improved compared to the C GrouP, but the difference of VAS change in the two groups was insignificant(p>0.05). Conclusions : Four weeks of acupuncture treatment significantly improved CSA, SPADI and VAS. The improvement of CSA and SPADI was significant(p<0.05) compared to untreated patients.

The purpose of this study was to investigate the effect according to the subject in goal setting to motor performance, Cognitive influence, and consistency of task by the method of Ⅲ-3. Eighty-four middh school boys were served as subjects. The results were as follows: 1. There were signifsaut differences among the groups in the motor performance by the subjects of goal setting. With the result of multiple Compaison, it showed that he highest score in performance. 2. This study showed that there're significant difference in the congnitive influence on the motor performance among the groups by the subjects of goal setting . With the result of multiple comparison, self-goad setting group employed congnitive methods while performance the motor task. 3. The consistency of task showed signifiant differences among the groups by the subjects of goal setting. With the result of multiple comparison, the degrees of consistency of task was higher in the group of self-goal setting than that of the other groups.

Power factor correction and harmonics reduction are important factors in the control policy of AC/DC power converter. This paper investigates 3-phase PWM AC/DC Boost converter in which the unity power factor is realized with a rapid control of output voltage. Instantaneous voltage control is performed for unity power factor through sinusoidal PWM method in this paper. The result of computer simulation and experiment indicates not only the unity power factor and harmonics reduction, but also the rippleless output voltage. AC/DC 전력변환장치에서 역률개선 및 고조파 감소는 기기의 효율적 이용 및 에너지 절약관점에서 매우 중요하다. 본 논문에서는 3상 AC/DC Boost 콘버어터에서 신속한 출력전압조정과 동시에 전원측의 상전류를 상전압과 동위상이 되도록 하는 단위역률운전에 관하여 연구하였다. 단위역률운전을 위하여 전류센서가 필요없는 순시전압제어를 수행하였으며 PWM 방식으로서 구현이 용이한 정현파 PWM 방식을 이용하였다. 그리고 시뮬레이션 및 실험을 통하여 단위역률 운전결과를 제시하였으며 고조파 분석결과 및 출력직류전압의 리플감소에 관한 결과도 제시하였다. 또한 실험을 통하여 3상 다이오우드 콘버어터와 상호비교도 수행하였다.

Prediction of thrapeutic response to radioiodine in Graves' disease is poorly understood. Although thyrotropin binding inhibitor immunoglobulin(TBII) level is a strong index for relapse after antithyroid drug medication, conflicting results are reported regarding its prognostic significance in Graves' disease treated with RAI. This study is dengned to evaluate possible relationship between post-treatment hypothyroidism and TBII in Graves' disease treated with RAI. Fourty two patient with Graves' disease after radioiodine treatment were studied retrospectively. The subject were divided into hypothyroid group and euthyroid or hyperthyroid group. We evaluated the association of hypothyroidism and TBII with radioiodine treatment dose. The mean age of hypothyroid group was 48±11 years and euthyroid or hyperthyroid group was 47±12 years. There was no difference in two groups. And there was no significant difference in post- treatment TBII between two groups(49.9±28.5%, 29.9±14.3%, p-value >0.05). The treatment-dose had no influence on post-treatment thyroid state. Euthyroid or hyperthyroid group was done with 13.6±6.9mCi and hypothyroid group was 17.0±10.4mCi(p-value > 0.05). TBII had no prognostic significance on long-term hypothyrodism in Graves' disease treated with radioiodine. And, treatment-dose had no influence on post-treatment thyroid state.
