본 논문에서는 쌍극성 임펄스형 데이터열을 AWQPSK(Amplitude Weighted QPSK) 신호로 변환하는 변조기를 탄성표면파 소자로 구현하고 그 특성을 측정하였다. 탄성표면파 변조기는 입력 비정규형 IDT와 출력 정규형 IDT로 구성되어 있으며, 중심 주파수 fc는 20MHz, 비트폭은 250nsec 를 갖도록 설계하여 압전물질인 $YZ-LiNbO_3$, substrate 위에 Photolithography방법으로 제작하고 그 특성을 측정하였다. 측정된 중심 주파수와 영점-영점 대역폭은 각각 20MHz와 8.8MHz이고 제 1 side lobe는 -60dB로서 이는 이론치와 거의 일치하는 결과이다. In this work an implementation of SAW based serial type AWQPSK modulator is studied. The SAW AWQPSK modulator consisting of input apodized IDT and output uniform IDT with center frequency of 20 MHz and bit rate of 4MHz has been designed and fabricated on $YZ-LiNbO_3$ substrate. Measured center frequency and null-to-null bandwidth are 20MHz, respectively. The sidelobe suppression is achieved 60dB below the peak mainlobe level. Measured responses meet the theoretical values with tolerable amount of deviation. SAW-based modulator simplifies the implementation of AWQPSK which uses complex pulse shape as a baseband pulse.

N/A Background : This is the studies about If the soldiers expose in the paraquat, how much have it influenced on themselves who participated in the Vietnam War and their second generation? and this is also researched about the factors that How differents do the symptoms according to their health conditions and a class of diseases?. First of all, We divided them into 3 groups as exposure duration and exposure degree of the paraquat and We gave marks against each steps, too. (< point 10: low group, point 11-19: middle group, > point 20: high group). We've focused in Does the high score really involves with their descendants who suffers from paraquat? as direct damages men during from June 1965 to February 1971 (72 persons) and their descendants (266 persons) who are in the Pusan veterans hospital and outpatients. Methods : It is completed by direct interview, telephone interview, army records, army history, and medical records with them. We've tried to minify sample bias as analyzing their information. We could contact only a few people among living in Pusan or Kyongnam province. Generally, someone including persons who couldn't get a damaging proofs from paraquat hardly joined us and the others strongly rejected the interview for this research. Results : Among the 72 participating soldiers in the Vietnam war, average age of patient is 53 years old (the youngest: 46 years old, the oldest: 64 years old), average of exposure score is 16 point (minimum: 1.9 point, maximum: 31.9 point), average of pregnant frequency is 5.2 persons, and average degree of smoking is 14.382 single cigarette (minimum: 4 single cigarette, maximum: 60 single cigarette). The second generation is suffering from abortion, skin disorder, still birth, congenital anomalies, weakness, visual disturbance, peripheral neuropathy in frequency. Conclusion : There's no relation between exposure score of paraquat and diseases of the descendants. (Korean J Med 58:221-226, 2000)

The purpose of this study was to investigate the applicability of the combination practice as a intervention for learning facilitatory effect by analyzing the effect of modeling with physical practice on the learning of three cascade juggling. 40 male college students participated as subjects, and were randomly assigned to one of the four groups; Action Observation(AO), Physical Practice(PP), Action Observation with Physical Practice(AO-PP) and control, with 10 subjects in each group. The experiment was proceeded as following the sequence; pretest, practice during 4 weeks, and retention test after 1 week. Performance outcome scale(successful juggling cycle) and performance productive scale(movement pattern, ball flight trajectory pattern) were measured from all subjects. the results showed that AO-PP group was improved distinctively in juggling cycle, movement pattern, and trajectory pattern as practical session proceeds, and those improvement was maintained in retention test, which was carried out after 1 week. Whereas, other three groups did not reveal significant improvement in any measured items as sessions. Taken together, the results of this study suggest that modeling with physical practice can be more effective than any one practice when beginners learn the motor skill like cascade juggling, which need specific temporal-spacial movement pattern of both upper extremities for successful performance.

[목적] 본 연구의 목적은 운동기능의 초기 학습단계에서 복잡한 목표지향적인 운동기능인 골프퍼팅시 고유감각의존훈련이 거리증가에 따른 지각판단 및 기능수행에 미치는 영향을 검토함으로써 기능학습촉진을 위한 효과적인 신체적 중재 방법으로서 고유감각의존훈련의 적용 가능성을 검토하는 것이었다.[방법] 남자 대학생 36명이 실험에 참여하였다. 모든 참여자들은 오른손 잡이로 정상이나 정상으로 교정된 시력을 지녔으며, 골프퍼팅 경험이 전무하거나 경험이 5회 미만인 초보자들었다. 그들은 고유감각의존집단, 시각의존집단, 그리고 통제집단 중 한 집단에 12명씩 무작위로 배정되었다. 본 실험은 사전검사, 연습세션, 그리고 사후검사의 순으로 진행되었다. 사전검사에서는 디지털 퍼팅분석기를 이용하여 참여자의 초기 수행지각거리의 정확성(i.e., 절대오차)과 실제수행거리의 정확성(i.e., 절대오차)을 분석하기 위해서 1-15m 퍼팅을 거리별로 1회씩(i.e., 총 15회) 무작위 순으로 수행거리를 측정하였다. 연습세션에서는 고유감각의존집단의 경우 눈을 감은 상태로 수행에 대한 고유감각의존 결과피드백에만 의존하여 1-15m 거리의 퍼팅을 무작위 순으로 거리별로 6회씩(i.e., 총 90회) 수행연습을 하였다. 시각의존집단의 경우에는 눈을 뜬 상태로 수행에 대한 시각의존 결과피드백에 의존하여 1-15m 거리의 퍼팅을 무작위 순으로 거리별로 6회씩(i.e., 총 90회) 수행연습을 하였다. 통제집단의 경우에는 수행에 대한 결과피드백 없이 눈을 뜬 상태로 1-15m 거리의 퍼팅을 무작위 순으로 거리별로 6회씩(i.e., 총 90회) 수행연습을 하였다. 사후검사는 사전검사와 동일하였다. 수행지각거리의 정확성, 실제수행거리의 정확성, 그리고 수행지각거리의 변화와 실제수행거리의 변화 사이의 상관관계가 절대오차 값을 이용하여 분석되었다.[결과] 사전검사에서는 집단 간 차이를 보이지 않은 반면에 사후검사에서는 세 거리조건(i.e., 1-5m 단거리, 6-10m 중거리, 11-15m 장거리) 모두에서 고유감각의존집단, 시각의존집단, 그리고 통제집단의 순으로 수행지각거리 및 실제수행거리의 절대오차가 유의하게 작은 것으로 나타났다. 아울러, 고유감각의존집단과 시각의존집단의 경우, 수행지각거리의 변화와 실제수행거리의 변화 사이에 유의한 정적 상관관계를 보여주었다. 하지만 그러한 상관관계의 정도는 거리조건과 훈련방법에 따라서 유의한 차이를 보이지는 않았다.[결론] 본 연구는 고유감각의존연습이 고유감각적 지각판단과 기능수행에 미치는 영향에 대한 통찰력을 제공함으로써 기능수행 및 학습촉진을 위한 신체적 중재로서 고유감각적 정보에 의존하는 고유감각의존훈련의 적용가능성을 보여준다. PURPOSE The purpose of this study was to investigate the applicability of proprioceptive-dependent training as an effective physical training method by analyzing the effects of proprioceptive-dependent training on the accuracy of perceived and actual distance as well as the correlation between the changes in the two variables. METHODS Thirty-six male college students took part in the experiment. Participants were beginners with no previous experience in golf or less than five times of experience. They were randomly assigned to one of three groups; proprioceptive-dependent training, visual-dependent training, and control, maintaining the same sample size per group. The experiment was carried out in the order of pre-test, practice section, and post-test. In the pre-test, putting was tested to assess the accuracy of perceptual and actual distance in the 1-15m distance in a random order using a digital putting analyzer. In the practice section, proprioceptive-dependent and visual-dependent training groups practiced a total of 90 putting, six times per distance with the eyes closed or open. The post-test was the same as the pre-test. The accuracy of perceived and actual distance and the correlation between the changes in the two variables were analyzed using the calculated absolute errors. RESULTS The results of this study showed that there was no difference between groups in pre-test. In contrast, in post-test, the absolute error was significantly decreased in the order of proprioceptive-dependent training, visual- dependent training, and control group in the three distance conditions. Besides, for the proprioceptive-dependent training group and visual-dependent training group, there was a significant positive correlation between the changes in the accuracy of perceived and actual distance. CONCLUSIONS These results provide insight into the applicability of proprioceptive-dependent training for enhancing motor performance by showing the effects of proprioceptive-dependent training on perceived distance, actual distance, and the correlation between the two variables.

The beauty industry in Korea is also required sensitivity, diversity, creativity and individuality. The systematic re-education of hairbeauty is reviewed here and the research covers the job characteristics of hair beauty professions, the study on the effects of satisfaction of work conditions and the employee turnover rate on the re-education to check up on the current situation of the re-education and to vitalize the condition. The results of the research can be summarized as follows. First, hair beauty professions are females in their 20’s with high school diplomas in general, however, in comparison with the recent researches more and more college graduates are gradually increasing. Second, as the current re-education conditions, most of hair beauty design institutes are running privately and there is a need of the re-education for the application of current trend and regular re-education is also much needed. Third, the improvement and development ways of the re-education are found as below. Due to the high demands of working hours, the professions are willing to have the re-education at their working places as for their shortage of time. The research also found that the re-education of the professions could support their work performances, the advancement and the relationship between customers. In conclusion, the higher the competence, self-esteem and with a variety of skills and expertise, the more professions feel the necessity of re-education which lower the turnover rate with the job satisfaction. Such findings will support to provide a better work environment for the hair beauty professions and the hair beauty industry will also be invigorated.

The purpose of this study was to analyze differences in the job-related physical capabilities of disabled workers by the type of disease and the frequency of participating in regular exercise. Fifty six male disabled workers participated in the experiment as subjects, and their muscular strength, muscular endurance, flexibility, and upper extremity function were measured. Analyses of the data revealed that the strength of both wrist flexors and left wrist extensor were higher in exercise participants than non-participants in the musculoskeletal disorder group. Upper extremity endurance was shown to be higher in exercise participants than non-participants in the poliomyelitis group, and upper abdominal and upper back endurances were shown to be higher in exercise participants than non-participants in the musculoskeletal disorder group. Upper abdominal endurance was higher in the poliomyelitis group than the spinal cord injury and brain injury groups. In terms of the upper extremity function, the brain injury group was slower than the musculoskeletal disorder group in Pegboard test, which measured the functional capacity of both upper limbs. In the Nine-Hole Peg test, which measured the agility and coordination of the hand, the spinal cord injury and the brain injury groups were slower than the poliomyelitis and the musculoskeletal disorder groups. These results suggest that participating in exercise on the regular basis may improve the job-related physical capabilities of disabled workers by increasing muscular strength and endurance.

First described at early 1970's as an angioimmunoblastic lyrnphadenopathy with dysproteinemia(AILD), angioimmunoblastic T-cell lymphoma(AIL-TCL) is a rare disorder and has generalized lyrnphadenopathy, fever, weight loss, skin rash, and polyclonal hypergammaglobulinemia. Although initially thought to be an abnormal immune reaction(AILD, or immunoblastic lymphadenopathy), AIL-TCL is now generally accepted as a T-cell lymphoma, because most cases have shown the clonal rearrangements of T-cell receptor genes. We report a case of 74 year old man, who visited Pusan Veterans Hospital with anorexia, fever, generalized edema and cervical lymphadenopathy, and diagnosed as AIL-TCL by neck lymph node biopsy.

A 67-year-old male visited Pusan Veterans Hospital due to general weakness and weight loss for 6 months. Physical examination showed non-tender 4 finger breaths sized splenomegaly and both inguinal and cervical lymphadenopathy. The white blood cell count was 25,300/uL with 91% morphologically mature lymphocytes. Bone marrow aspirate revealed hypercellularity with 74.5% lymphocytes morphologically similar to peripheral lymphocytes. The immunophenotpying study of lymphocytes displayed the phenotype of CD19(+), CD20(+), HLA-DR(+), sIg(+) but CD5(-). We concluded that this patients's diagnosis is CD 5 negative B-cell chronic lymphocytic leukemia.
