J. R. PARK, B. Y. PARK. The analysis of Electromyograhpy during Professional & Amateur Golfer's Iron Swing. Korean Journal of Sport Biomechanics, Vol. 14, No. 2, pp. 167-178, 2004. The purpose of this study was to describe and compare the selected electromyographical muscle activities of trunk and hip during Professional and Amateur golfer's Iron swing. Using surface electromyography, we evaluated muscle activities in 6 male professional golfers and 6 male amateur golfers during the golf iron swing. Surface electrodes were used to record the level of muscle activity in the right abdominal oblique, left abdominal oblique, right erector spinae, left erector spinae, right rectus abdominis, left rectus abdominis, right gluteus maximus, left gluteus maximus muscles during the golfer's swing. These signals were compared with IEMG(Integrated EMG) which was normalized by %RVC(Reference voluntary contraction). The golf swing was divided into three phases: take away, forward swing-acceleration, follow-through. We observed patterns of trunk muscle activity throughout three phases of the golf swing. The results can be summarized as follows: LES(Left Erector spinae) had statistically significant difference in take away and forward swing-acceleration phases. It was showed no significant difference in follow-through phase.

The purpose of this study is to provide the basic data for the development of the various Education policies which can improve the problems after understanding the actual situation of the leisure activities of the middle school students, surveying and diagnosing the consciousness about the leisure activities, and analyzing problems. As for the subjects of tills study, the middle students who are currently enrolled in Y middle school in Suwon, Kyung-ki-do was selected as the population, and then totally 450 students were selected as the samples after the random sampling, The research subjects were totally 434 students who answered the survey among those 450 students. The survey papers which contain the ailing or unfaithful answers and contents among the total 434 students were excluded from this study. Therefore, the actual subject people who were applied to this study were totally 420 students. The sexual composition of the subject people are 24 male students(57.6%) and 178 female students(42.4%), and the male students have the a little higher rate than the female students. For the analysis of the data, in this study the frequencies analysis, cross analysis, independent t test, and one-way ANOVA were used as the useful statistical technique, the scheffe method was executed. At this time, the meaningful standard was analyzed after setting up as α=0.5. Through the above mentioned research method and course and based upon the produced research result, the following conclusion was induced. Firstly, the result of the analysis about the time of the leisure activities of the young people showed that the 120 students(28.6%) answered average under 2 or 3 hours to the question that how long leisure time per day you have, and this is the most frequent answers, and 105 students(25%) answered under 1 or 2 hours, Thus, the leisure time of the middle school students was surveyed as average under 2 or 3 hours per day and this was over 53.6%, and it was demonstrated that the students and young people were not active and emotional, and also enjoying the inactive and monotonous leisure activities because of the burden due to the time caused by the excessive studies and preparation for the entrance examination. Secondly, when seen through the analysis result of the actual condition of the leisure activities of the young people, it was known that there is the trend that the leisure activities of the young people are made up of the individual(houses of relatives, private educational institution), and merrymaking(cafe, billiard hall, bowling hall, karaoke room, and video-watching room) events. Thirdly, in case of the place for the leisure activities, it was shown that the female students enjoyed 'Library, municipal cultural center', 'cafe', 'karaoke, video-watching room', 'window shopping, street sightseeing', 'bookshop', 'cultural enjoyment', and 'private educational institution' rather than the male students did, and there was the meaningful difference statistically(P<.05). In the other hand, the male students enjoyed 'athletic facility', 'billiard hall, bowling hall', 'juvenile group', 'amusement facility, cartoon room, PC room' rather than the female students, and there was the meaningful difference statistically(P<.05). According to each the grade, in case of the 1st grade showed that they stayed 97 minutes in the karaoke and video watching room, and 94 minutes in the window shopping and street sightseeing, and 106 minutes in the amusement facility, and 21 minutes in the bookshop, and in case of 2nd grade, they were shown that they stayed 64 minutes in the reading room, and 35 minutes in the billiard room and bowling room, and lastly in case of 3rd grade, they were shown that they stayed 51 minutes in the instant food store and 247 minutes in the private educational institution. In case of the contact time with the mass media, there was no difference in the activities such as 'printing media such as the news papers and magazines', 'watching TV, but there was the meaningful difference according to the sexual distinction in the time for 'listening the radio', and 'using computer' statistically(p<.05). When concretely examined, the female student had average 34 minutes for listening the radio, and this is over 13 minutes than the male students whereas the male students spent 129 minutes in 'computer', and this is 37 minutes more than that of the female.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

Aims: The number of elderly patients diagnosed with hepatocellular carcinoma (HCC) has been increasing because the increase in the longevity of the general population. But there is no proper management based on age stratification in elderly patients. We compared clinical characteristics, outcomes and treatment efficacy, safety between oldest-old (aged more than 85 years), middle-old (aged between 80 and 85 years) and young-old (aged between 75 and 80 years) patients with HCC. Methods: We conducted a retrospective cohort study, from January 2010 to December 2016, at Chonnam National University Hospital. A total of 550 elderly patients whose data included demographics, co-morbidity, etiology of liver disease, presence of cirrhosis, staging of HCC, treatment modality and treatment related adverse event were evaluated retrospectively. Also overall survival was assessed in enrolled patient. Results: Fifty one patients (oldest-old; median 87 years old), 153 patients (middle-old; median 82 years old) and 346 patients (young-old; median 77 years old) were diagnosed with HCC. Both oldest- and middle-old patients, compared to young-old patients had significantly lower rate of alcohol-related disease (13.7% vs 20.9% vs 34.1%, P = 0.001). There were no significant difference in underlying sex, body mass index, presence of co-morbidity, hepatitis C-related disease and stage of HCC. The Child-Pugh class (CPT class A 88.9% vs 84.1% vs 83.6%, CPT class B 11.1% vs 15.9% vs 15.0% and CPT class C 0.0% vs 0.0% vs 1.3%, respectively, P = 0.912) and Model for End Stage Liver Disease score (mean MELD score 7.22±3.34 vs 5.88±3.01 vs 5.77±3.14, P = 0.166) were no significant difference between the patients with active treatment. The modified UICC staging (stage I 5.6% vs 17.1% vs 18.6%, stage II 55.6% vs 46.3% vs 47.3%, Stage III 22.2% vs 24.4% vs 24.8%, Stage IV-A 11.1% vs 6.1% vs 4.9% and Stage IV-B 5.6% vs 6.1% vs 4.4%, respectively, P = 0.826) and Barcelona Clinic Liver Cancer staging (stage 0 5.6% vs 9.8% vs 9.3%, stage A 16.7% vs 17.1% vs 22.1%, stage B 27.8% vs 29.3% vs 24.8%, stage C 50.0% vs 43.9% vs 41.2% and stage D 0.0% vs 0.0% vs 2.7%, respectively, P = 0.878) were no significant difference between the patients with active treatment. Furthermore, there were no difference between the age groups in treatment modality (Surgical resection 0.0% vs 3.3% vs 5.2%, P = 0.166; Radiofrequency ablation 2.0% vs 8.5% vs 11.0%, P=0.113; Transcatheter arterial chemoembolization 21.6% vs 34.6% vs 41.6%, P=0.014; Best supportive care 62.7% vs 40.5% vs 29.2%, P < 0.001), adverse event related treatment (P = 0.731) and disease-free survival days (329 .3±309.1 days vs 271.7 ± 414.2 days vs 357.2 ± 511.6 days, P = 0.336). Multivariate analysis showed that age, performance status, CTP class, MELD score, modified UICC staging, presence of portal vein thrombosis and ruptured HCC are risk factors for mortality. Conclusions: Clinician should make an active treatment in elderly patients with HCC not a age but performance status, liver function and disease status of cancer.

This paper is intended as an investigation of fault location for underground line. Over the past few decades a considerable number of studies have been made on protection of underground line. However, these approaches require the interruption of electric power supply from source for fault location estimation. Therefore, we proposed fault location algorithm for underground line protection without interruption of electric power supply. Cross correlation function is used in this algorithm. Also, EMTP data is used to demonstrate the capability of the proposed fault location algorithm.

This paper describes the Hybrid Intelligent controller using Modular Recurrent Neural Network(MRNN) controller and Simplified Indirect Inference Method(SIIM) Fuzzy PD controller, which is used to control a three axis PUMA robot. First, the SIIM Fuzzy PD controller is derived from the conventional continuous time linear PD controller. Then the fuzzyfication, control-rule base, and defuzzification using SIIM in the design of the fuzzy controller are discussed in detail. The proposed controller enhances the self-tuning control capability. Second, the modular recurrent neural network(MRNN) controller has additional feedback neurons in the conventional multi-layer neural network. the learning law based on gradient search techniques has been used. The simulation results of a three-axis PUMA robot shows that comparing to the MRNN controller plus fixed PD controller, the proposed method gives the better precision on the tracking of the given circular trajectory and the better approximation for three-axis respectively.

This study was carried out with the purpose of looking into the regulation of gene related to anther development, and applying their promoter to induce male sterile plants and restore their fertility. Progenies of transgenic male sterile tobacco plants containing anther specific promoter (BAN215) and diphteria toxin A (DTx-A) gene were analyzed by danamycin screening and pollen observation. DTx-A gene in male sterile plants was confirmed by PCR with the two synthetic primers, 5'-AACTTTTCTTCGTACCAC-3' and 5'-GCTTTCGCCTGTTCCCAG-3', from the sequence of DTx-A genes. The fragment of 350bp was appeared when the PCR product of 428 bp was digested with Rsal. pDTx-2 containing DTx-A gene was used as a control (DTx). Some of them were double transformed with the construct of BAN215 promoter and antisense DTxA (pKDA215b) to test restoration of fertility.
