This study was performed to explore the effects of a dance therapy on physical and psychological characteristics in the elderly. The design of this study was a non-equivalent pre-post test experiment. The subjects consisted of elderly persons living in a facility located in Suweon and Bucheon. Fifty eight subjects, aged between 65 and 93 years who had normal cognition, sensory function, balance, and resting blood pressure. They underwent tests of balance, flexibility, muscle strength, depression, and anxiety as baseline data before dance therapy, and at 6th week and at the end of the 12nd week after following dance therapy. Twenty seven elderly persons were assigned to the experimental group and participated with the dance therapy between April and July, 1998. The dance therapy was developed by the author with the help of a dance therapist and a physiatrist. This therapy was based on the Marian Chace's dance therapy and Korean traditional dance with music. The dance therapy consists of 50 minutes session, 3 times a week for 12 weeks. One session was consisted of warming-up, expression, catharsis, sharing, and closing stage. The intensity of the dance therapy was at the 40 % of age-adjusted maximum heart rates. Data were analysed with mead standard deviation, Chi-square test, unpaired t-test, repeated measures ANOVA, and Bonferroni multiple regression using SAS program. 1. The results related to the physical characteristics were as follows : 1) The balance (standing on one leg, walking on the balancing bar), flexibility and muscle strength (knee extensor, knee flexor, ankle plantarflexor and dorsiflexor) of the experimental subjects significantly increased over time mere than that of the control subjects. 2) The experimental group had significantly higher score for balance, flexibility, muscle strength of knee extensor, and knee flexor than the control group at the 12nd week after dance therapy. 3) The experimental group had significantly higher score for muscle strength of ankle dorsiflexor and plantarflexor than the control group at the 6th week and the 12nd week after dance therapy. 2. The results related to psychological characteristics were as follows : 1) Scores of Geriatric Depression Scale, Hamilton Depression Rating Scale, and Zung's Self-rating Anxiety Scale of the experimental group were significantly decreased over time more than that of the control group. 2) The experimental group had significantly lower score for depression than the control group at the 12nd week after dance therapy. 3) The experimental group had significantly lower score for anxiety than the control group at the 6th week and the 12nd week after dance therapy. The findings showed that the dance therapy could be effective in improving the balances, flexibility, and muscle strength of lower limb, and effective in decreasing the depression and anxiety of the elderly. Additional merits of the dance therapy would be inexpensiveness, easy accessibility, and increasing interpersonal relationship. It can be suggested that the dance therapy is effective in the health promotion of the elderly.

본 연구의 목적은 kinesio taping 적용이 근력 향상에 미치는 영향을 직 간접적으로 관찰함으로써 운동 수행시의 상해예방 및 수행력 향상을 위한 수단으로서의 taping 요법에 대한 기초 자료를 제공하는데 있었다. 본 연구는 남자 대학생 10명을 대상으로, 근력 향상의 정도를 직접적으로 관찰하기 위하여 1RM test와 Cybex test를 실시하였으며, 생리학적 변인으로는 CK, LDH, phosphorus, ammonia, creatinine, IGF-I의 6가지 혈중 성분을 분석함으로써 피로와 근 손상의 정도를 분석하였다. 본 연구를 통하여 kinesio taping은 근력향상의 직접적인 지표(1RM, 등속성 운동능력)에는 긍정적으로 작용했지만, 85%-1RM의 웨이트트레이닝 시의 근 피로 또는 근 손상 지표물질의 농도는 유의하게 감소시키지 못함을 알 수 있었다. 하지만 본 연구의 결과만을 가지고 taping의 적용이 피로 및 근 손상 완화 효과가 없다고 판단할 수는 없을 것으로 생각된다. 왜냐하면, 본 연구에서의 피로 및 근 손상 유발 수단인 85%-1RM 웨이트트레이닝은 고강도의 운동이며 운동에 소요된 시간도 40분 정도로 장시간이지만 다양한 근육부위에 적은 반복수와 set를 적용하였기 때문에 피로 및 근 손상 지표물질의 축적이 현저하지 않았을 수 있기 때문이다. 이는 taping 적용 후 나타난 여러 혈중성분들의 감소(Creatinine 제외) 경향으로 설명할 수 있으며, 실제로 선행 연구 중 특정 대근육에 대한 반복적인 운동에 kinesio taping을 적용하여 피로 및 근 손상 완화를 입증하기도 하였다. 본 연구가 가지는 의의는 특정 동작에 있어서의 근력 향상을 중점적으로 관찰한 연구가 아닌, 전신에 대한 taping을 적용한 후 각 근육 부위에 어떠한 영향을 미치는지 다양한 관점에서 관찰하였다는 데 있다. 이후의 연구에서는 본 연구에서 관찰한 변인들 이외에도 신경계통의 변인들과의 상관관계도 함께 관찰 하는 통합적인 연구도 의의가 있다고 하겠다.

잭업 드릴링 리그 (Jack-up drilling rigs)는 해양자원개발 분야 중 석유 및 가스 탐사 산업에서 널리 사용되는 대표적인 해양구조물이다. 이러한 잭업 구조물은 대체로 얕은 수심에서 사용하도록 설계되었지만 에너지 산업의 추세로 대수심 및 가혹한 환경 조건에서도 사용이 가능한 설계가 요구되고 있다. 이러한 잭업구조물의 운영환경 확장에 따라서 과도한 설계를 최소화하고 신뢰성 반영된 설계법이 요구되었다. 기존의 해양구조물 산업에서 잭업 구조물의 설계법은 사용(혹은 허용)응력 설계 (WSD: Working (or Allowable) Stress Design) 방법을 사용하여 설계가 되고 있었다. 이러한 설치환경변화에 따라서 충분한 신뢰성을 확보가 가능한 하중 및 저항계수 (LRFD: Load and Resistance Factored Design) 방법을 최근 개발되었고 규정화가 되었다. LRFD 방법은 통계적 기반으로 한 한계상태설계 개념으로 잭업구조물의 구성구조부재의 하중과 전산수치해석을 이용한 강도의 불확성을 하중 및 저항 계수로 표현하는 설계법이다. 개발된 LRFD 방법은 실제 잭업구조물 설계의 적합성 판단을 위하여 기존의 WSD 방법과의 정량적인 비교 분석이 반드시 필요하다. 따라서 본 연구는 기존의 WSD와 LRFD 방법으로 이용하여 실 잭업 구조물의 레그 구조를 대상으로 상용유한요소해석코드를 이용하여 정량적인 UC (Unity Check)값을 기반으로 비교 분석하였다. 분석된 결과로 다양한 환경하중조건 하에서 LRFD 방법을 사용하여 잭업구조물의 레그(Leg) 설계에서 상당히 합리적인 UC 값을 가지고 기존 대표적인 WSD기법 중에 하나인 API-RP 코드 대비 약 31 % 차이가 분석되었다. 따라서 LRFD 설계 방법이 WSD 방법에 비해 구조 최적화 및 합리적인 설계에 더 유리하다는 것을 확인할 수 있었다.

The objective of this study is to investigate the market of fitness compression wear as well as to design an optimal fitness compression wear by analyzing the muscle and movement characteristics of the elderly women in Korea. In this regard, research for functional garments is needed to increase muscle activity of elderly people during physical exercise. Firstly, we investigated the brand, design, size, material, and pattern of fitness wear based on the market survey. Secondly, we identified preference, evaluation items, evaluation method, and pattern design method based on the literature review. Finally, in addition, the motion type, range, angle to improve the muscle strength of the elderly were investigated and the maximum muscle strengths of each motion were analyzed by using 2007 Size Korea data (n = 386). It is also designed for muscle fatigue through exercise and rapid fatigue recovery after exercise. The evaluation methods for fitness compression wear were classified as motor functionality, physiological comfort, pattern and material suitability evaluations. The muscle strength at leg (pushing force) and waist (lifting force) of the ages of 60 to 69 years old showed 239.3 N and 274.5 N, respectively, which were the lowest forces compared to younger age groups. By applying these results to the design process of fitness wear, it is anticipated that the fitness wear will have a proper fit to the body shape of elderly people in South Korea as well as it can increase muscle efficiency to promote physical capability and healthy life for senior people.

PURPOSE: The aim of this study was to provide the standard value of the Five Times Sit to Stand Test (FTSST) measurement on the daily life independence of the elderly in Korea and examine the effects of this test on their daily lives. METHODS: This study was conducted on elderly people over 65 years of age living in Gyeongsangbuk-do, Korea. FTSST was performed while sitting position on a chair. The subjects were classified into independent and dependent living groups according to their lifestyle, and their influence was then examined through logistic regression analysis. To determine the usefulness and cut-off value of the FTSST, the analysis was performed using the ROC curve. RESULTS: The elderly were more likely to live in a group rather than independently as the FTSST time increased (p<.05) (OR=1.098). The area of the lower part of the ROC curve was .707, and as the FTSST increased, a subject was more likely to live in a group rather than independently (p<.05). The cut-off value was assigned to the point where both the specificity and sensitivity were at the coordinates. The sensitivity and specificity were .626 and .753, respectively at 15.62 seconds. CONCLUSION: The elderly in Korea are more likely to live a group-dependent lifestyle than live independently; the likelihood of this outcome is increased further for every additional second beyond 15.62 seconds. The loss of independence of daily life could be predicted based on the status of a subject's lower leg strength using the FTSST.

The purpose of this study was to verify exercise effect of horse riding exercise according to estimate basal physical fitness and activities of daily living(ADL) function in the aged. Participants were nineteen peoples who have no impediment of activity. They performed horse riding exercise using SRider(Neipplus, Co., Korea) at sixty minutes a day. Exercise has progressed three days a week for eight weeks. We measured trunk flexion, sit up, whole body reaction, leg strength and maximal oxygen uptake as basal physical fitness. Also three meter gait, single stance with eyes opened and single stance with eyes closed as ADL function were estimated once a month. The result of legs strength and whole body reaction showed the higher significantly than before the exercise. Moreover, the result of three meter walking ability only increased significantly among the ADL function. This means that horse riding exercise might be activated continuous muscular contraction with maintained tonus of muscle. We thought that continuous movement of horse riding could be lead to isometric muscle contraction in lower limbs. Our study found that horse riding exercise could improve lower strengths and muscle reaction for exercise effect. Also we suggested that horse riding exercise could be adapted to exercise methods that could provide rehabilitation and treatment enough for the aged or disabled person.

The purpose of this study was to determine the effectiveness of sit-to-stand training on unstable surfaces in individuals with stroke. Nineteen subjects with chronic stroke were divided into two groups: an experimental group (10 subjects) and a control group (9 subjects). They received 30 minutes of Neuro-developmental therapy (NDT) treatment, and sit-to-stand exercise for 15 minutes three times a week for four weeks. During the sit-to-stand training, the experimental group performed on an unstable AIREX balance pad, but the control group performed on a stable surface. Balance ability and weight-bearing distribution during quiet standing were measured before and after training period using the 7-item Berg balance scale-3P (BBS-3P) and the Five-times-sit-to-stand test (FTSST). In addition, the muscle strength of the knee extensor was evaluated before and after the training period. The results were as follows: 1) The weight-bearing distribution forward of the affected leg, increased significantly in the experimental group after the four-week intervention (p<.05), 2) The 7-item BBS-3P and FTSST increased significantly in the experimental group after the four-week intervention (p<.05), 3) The knee extensor muscle strength in both groups increased significantly after the four-week intervention (p<.05). In conclusion, the results of this study did not show that the sit-to-stand training on an unstable surface was more effective than on a stable surface. However, the results suggested that sit-to-stand training is effective in the balance training of stroke patients.

This study examined the relationship between body fitness and body composition as well as the body fluid and intracellular fluid (ICF) of extremities to determine body composition's quantitative criteria for body fitness. Multiple-frequency segmental bioelectrical impedance analysis and the physical fitness test provided by the Ministry of Education, Culture, Sports, Science and Technology were used to measure body composition and physical fitness, respectively. The test results showed that in women in their fifties, the correlation between the amount of body fluid in the upper limbs and grip strength was r=.654 (p<0.01) for the right arm and r=.445 for the left while that between the amount of ICF in the upper limbs and grip strength was r=.708 (p<0.01) for the right and r=.323 for the left. Also, in women in their fifties, the correlation between the amount of body fluid in the lower limbs and the result of a repetitive side jump test was r=.730 for the right leg and r=.753 for the left (p<0.01 for both), and that between the amount of ICF and the counts for the right and left legs was even higher with r=.742 and r=.763, respectively (p<0.01 for both). The body fluid and ICF volumes in the right extremities exceeded those in the left, and physical fitness was correlated with both body fluid and ICF. These findings indicate a connection between physical fitness and body fluid and ICF, suggesting that body composition may help predict physical fitness.
