The purpose of this study was to examine the effect of organized walking (n=9) and badminton exercise (n=9) on bone density, maximal oxygen consumption, and leg extensor intake during 6-month period of experiment with middle-aged women(48-56 years). Subjects (n=18), regularly participating to a social sport oenter, were practiced an assigned exercise 3 times a week and measurements were taken every 3-month. after the program being initiated Bone density was measured by DEXA method, VO?? by a rpogressive work load exercise, and leg extensor by isokinetic equipment. The following results were obtained from data analyses : 1. For walking group, the 6-month exercise with a regular time interval resulted in an increase in the bone density of back lumber (L1-L4). On the other hand, for badminton group, an increase was shown in the bone density of head of thigh. 2. For both groups, les extensor was significantly increased over the 6-month experimental period. 3. Subjects in walking exercise group showed an significantly increased VO?? over the experimental period while badminton group did not. These conclusions suggest that an exercise prescriptor should design an exercise program such a way that it includes both a resistance training and aerobic exercise in order to increase bone density, which has a prevention effect against aging and bone fracture, as well as to enhance strength of leg muscle and VO??.

윤성원,유재충 慶熙大學校 體育科學大學 1990 體育科學論叢 Vol.- No.3

The purpose of this study was to compare and verify validation of anaerobic power measurement by Wingate test and Cybex test. Subjects were selected from Hand ball players of Kyung-Hee University whose careers were over 5 years The study utilized isokinetic contraction test and wingate test by Cybex-Ⅱ system and Computerized bicycle-ergometer. The results of this study were as follows ; 1. Correlation coefficients of 0.86 and 0.84 were found between wingate test and Cybex test in the maximcua and minimum of anaerobic power. 2. Maximal blood lactate concentration of Wingate test and Cybex test were 8.64 ±0.53 mmoles/ℓand 8.44 ±0.68 mmoles/ℓrespectively, not revealing a statistical significant difference(p>.05) in 3 minute's recovery. 3. Change of blood lactate concentration before and after Wingate test and Cybex test showed same phases of in rest, all-out and recovery(3,5 and 10 minutes).

The purpose of this study is to analyse the relation between peak torque and revealed angle with using isokinetic load speed in low and high speed. To achieve it, we make use of experiment study with each of 50 people female and male. The size of sample is total 100 people. This experiment aims at measurement of using isokinetic machine in cybex. The summary of this result is as following; 1. The more increasing in load speed, revealed angle of peak torque show range of motion late. 2. In case of peak torque do not raise to women, it is negative relation to an revealed angle. 3. In isokinetic motion, from load speed 60° sec show the revealed speed of peak torque in case of man and women; A protractor display from 53° to 54° and a flexor from 34° to 38° that. 4. In isokinetic motion, from load speed 60° sec show the revealed speed of peak fortque in case of man and women; A protractor display form 44°~45° and a flexor form 41° to 44° that.

한국과 일본 여자 축구 대표선수의 슬관절을 중심으로 신전 및 굴곡운동시 발휘되는 각근력의 근기능을 평가, 비교하기 위해서 한국 여자 축구 선수 15명과 일본 여자 축구선수 17명 총 32명을 대상으로 등속성 근력측정장치인 사이백스(Cybex-3)를 이용하여 근력, 근파워 및 근지구력을 측정, 비교 분석한 결과를 요약하면 다음과 같다. 1. 한국과 일본 여자 축구 대표선수의 등속성 근력발휘는 신전 및 굴곡력 모두 각 부하속도에서 차이가 없는것으로 나타났으나 느린부하속도에서는 한국 여자 축구선수, 빠른 부하속도에서는 일본여자 축구선수가 다소 높은 것으로 나타났다. 2. 동측근력의 균형적 발달에 있어서 유의한 차이는 없으나 일본 여자 축구 대표선수가 측정부하속도 모두에서 한국 여자 축구 대표선수보다 조금 높은 것으로 나타났다. 3. 240°/sec 부하속도에서 50회 신전 및 굴곡반복 운동시 발휘된 평균파워는 신전력에 있어서 한국선수가 일본선수보다 유의한 차이(p=.012)로 낮게 발휘되었으며 굴곡력에서도 낮게 발휘되었으나 유의한 차이는 보이지 않았다. 4. 240°/sec 부하속도에서 50회 신전 및 굴곡반복 운동시 발휘된 총일량과 근지구력비에서 신전력 총일량에서는 한국 여자축구선수가 유의한 차이(p=.021)로 높게 발휘되었으나 굴곡 총일량, 신전 및 굴곡 근지구력비에서는 두 집단간 유의한 차이가 나타나지 않았다. 이와 같은 결과로 한국 여자 축구선수의 경우 경기력에서 우수한 일본선수와 전체적 체력 평가에 의한 비교분석이 이루어지지 않았으나 축구선수에게 매우 중요한 각근력에서 차이가 없는 점을 고려할 때 한국여자 축구경기의 경우 경기력 향상을 위한 노력으로 많은 실전 경험과 기술 트레이닝이 이루어진다면 일본 여자축구와 비교할 수 있는 경기력 향상이 기대될 수 있을 것으로 본다. The purpose of this was to compare muscula strength, muscle power and muscle endurance for lower limber of Korean and Japan woman soccer player. The Cybex-Ⅱ system of measurement equipment was used to measure these isokinetic muscle function. The subjects were 15 korean elite woman soccer player and 17 Japan elite player. The summary of this results is as following: 1. There was no difference in isokinetic strength of flexion and extension at all speed range between Japanese and Korean female soccer player. Korean players showed higher muscle strength at low speed but Japanese players revealed higher muscle strength at high load speed. 2. In terms of ipsilateral balance, Japanese players displayed higher results than Korean player but there was no significance. 3. Japanese players had a greater muscle mean power of extensor at 240°/sec than that of Korean players(p=.012) but there was no sinificance in muscle mean power of flexiors. 4. Regarding total work and muscle endurance ratio of flexiors and extensior, Korean players showed higher results in total work but the rest of them did not have significant differences.

원자로 Stud Bolt 의 결함검출을 위한 초음파 신호처리 기법개발

Bolt failure is a hazard factor for the safety of reactor vessels in nuclear power plants. However, in the practical application of ultrasonic technique for crack detection in stud bolt, the classification of crack signal from the signals reflected from threads in stud bolt is very difficult. In this study, shadow effect technique combined with new signal processing method has been investigated to enhance the detectability of small crack initiated from root of thread in stud bolt. The key idea of new signal processing concept is based on the fact that the shape of waveforms from the threads is uniform since the shape of the threads in a bolt is same. If some cracks exist in the thread, the flaw signals are different from the reference signals. It has shown that the small flaws can be effectively detected by novel ultrasonic technique combined with this new signal processing concept.

연구목적 : 1998년 정신건강의 날 기념 한국인 우울증 선별의 날 행사에 자발적으로 참여한 참가자들의 사회인구 통계학적 특성을 분석하고 우울증 선별검사 결과를 평가하기 위하여 본 연구를 시행하였다. 방 법 : 8개 병원에서 얻어진 619명의 자료를 사용하여 선별검사로 밝혀진 우울증의 유병율과 사회인구통계학적 특성 및 응답자의 정신과적 치료를 포함한 과거력 등을 조사하였다. 결 과 : 우울증 척도 점수는 응답자 전체 평균 57.5±13.8로 경도의 우울 증상이 있는 것에 해당되었다. 전체 응답자의 69.5%(430명)가 최소한 경도 이상의 우울 증상을, 43.1%(267명)가 중등도 이상의 우울 증상을, 18.4%(114명)가 고도의 우울 증상을 보였다. 고도의 우울 증상이 있는 응답자의 56.8%와 중등도의 우울 증상이 있는 응답자의 63.9%가 정신과 치료를 받은 적이 전혀 없었다. 나이가 29세 이하인 것과 전임근무 중인 직업상태는 각각 나이가 60세 이상인 것과 직업이 없는 것에 비교하여 우울증으로부터 보호하는 인자임을 시사하였다. 결 론 : '1998 한국인 우울증 선별의 날' 행사를 통하여 많은 우울증 환자들을 선별해낼 수 있었고, 이들의 우울 증상은 몇몇 사회인구통계학적 특성과 유의한 관계가 있음을 확인하였다. 우울증 선별의 날 행사를 통한 우울증에 대한 교육과 우울증 선별검사는 치료받지 못하고 있는 우울증 환자 및 기존의 치료 중인 환자 모두에게 유용한 프로그램임을 알 수 있었다. Objectives : This study was performed to analyze the sociodemographic characteristics of participants in '1998 Korean Depression Screening Day' and to evaluate the results of the screening test. Methods : By using the survey results of 619 volunteers from 8 hospitals, the authors examined the prevalence of depression detected at the screening test and sociodemographic characteristics and the psychiatric treatment history of respondents. The assessment measure was the Zung Self-Rating Depression Scale. Results : The mean depression score of all participants was 57.5±13.8 and it came under mild depression. Of all participants, 69.5%(N=430) had at least mild depressive symptoms, 43.1%(N=267) had at least moderate symptoms, and 18.4%(N=114) had severe symptoms. Never have 56.8% of respondents in the severely depressed range and 63.9% of those in the moderately depressed range had psychiatric treatment. The results suggest that the age group of 29-year-old or younger(relative to 60-year-old or older group) and full-time employment status(relative to unemployment) are protective factors of depression. Conclusions : By '1998 Korean Depression Screening Day', many depressed patients were detected and their depressive symptoms had statistically significant relationships with some sociodemographic characteristics. The results suggest that the education and screening test programs for depressive illness facilitated by Depression Screening Day are useful to the patients regardless of being under current treatment or not.
