The objective of this study was to investigate the effect of storage time on fresh boar semen in Androhep and Beltsville Thawing Solution (BTS). Boar semen samples extended in each extender were stored at 17℃ up to 4 days. Sperm motility kinematics was evaluated by computer assisted sperm analyzer (CASA) and capacitation status by chlortetracycline (CTC)/Hoechst 33258 staining. Sperm motility (%) was not decreased during storage in BTS and Androhep. No significant difference between extenders was observed. Only significant differences in kinematic parameters on linearity during storage were found. The percentage of dead sperm significantly decreased during storage (p<0.05). Also the percentage of noncapacitated, capacitated, and acrosome-reacted sperm significantly modified during storage (p<0.05). However, there was no significant difference between extenders except proportion of capacitated sperm. This finding supported that modification in these parameters was not significantly different between extenders during this short-term storage. Our finding strongly indicated that both Androhep and BTS maintained favorable conditions for motility, motility kinematics, and capacitation status during short-term storage. Despite modifications in some parameters were apparent during sperm storage in extenders, these may not affect the fertilizing capacity of boar semen.

The purpose of the study was to determine the effects of balance training with 'TETRAX' system, a balance training and assessment tool, on balance and mobility in acute hemiplegic patients. Nineteen matched subjects were assigned randomly into either an experimental group or a control group. An experimental group with 10 subjects received balance training with 'TETRAX' exercise program and conventional physical therapy interventions 5 times per week during 4 weeks. A control group with 9 subjects received conventional physical therapy interventions 5 times per week during 4 weeks. Outcome measures were taken before and after 4 weeks of interventions using the Stroke Rehabilitation Assessment of Movement (STREAM), the Berg Balance Scale (BBS), gait speed, and the fall down index. Results indicated that both exercise groups improved significantly in STREAM, BBS, and gait speed (p<.05). The experimental group had a little improvement than the control group. Both exercise groups did not show statistical significance in fall down index (p<.05). Following 4 weeks of intervention, except gait speed there was no statistically significant difference between two groups. However, these findings suggest that conventional physical therapy interventions with visual feedback training could be effective on improving balance and mobility than conventional physical therapy alone in acute hemiplegic patients.

WMSD occurs by accumulating the visible position and movements. Therefore, it is easier to prevent WMSD from occurring than other diseases when each employee is aware of the factors which cause WMSD. Hence, We need to develop exercise remedy, which can be done without using any exercise equipments and regardless places. The exercise prescription for those for LBP was to do the upper body exercise remedy twice in the morning and another twice in the afternoon and the spinal exercise remedy and the lower body exercise remedy once in the morning and once in the afternoon. We measured their maximum muscular strength every second week using a fitness machine so that we could compare the differences of the muscular strength of the test group and the comparison group. Therefore this research presented the fact that the exercise remedy is effective to prevent and cure LBP through a scientific test. And it confirmed that the exercise remedy by the Ergonomic exercise prescriptions is effective on LBP.

In this paper, I examine the development of the second stage of Chicano muralism and compare it with the first stage of the Chicano Mural Movement that was born out of the Civil Rights Movement. I then discuss the different aspects of the first stage in relation to the birth of institutionalized public art and question how Chicano murals influenced public art and, conversely, how mainstream public art transformed some of the attitudes and practices of Chicano muralism. Chicano murals initially functioned as a political mouthpiece for Chicano’s human rights and as a tool to recover the Chicano people’s cultural pride and legacy. However, the murals gradually developed into public art projects supported by the city or federal governments, who regarded them as an economic way to effectively communicate with the community. In this process of institutionalization, muralists became increasingly concerned with aesthetic quality and began to work more systematically. For example, amateur artists or community participants who produced the earlier murals were transformed into mural experts. Chicano essentialism and the politically volatile themes used previously were phased out and the new murals began to incorporate diverse subjects and people, for example, native culture, Blacks, and women. This phenomenon reflected the changing emphasis on multicultural understanding. This kind of institutionalization did not always draw positive results. Inadequate funds were the primary concern over the actual subject and creation of the mural work. Artists reduced the strong political metaphors and aestheticized the mural forms. However, their work was productive as well: thorough research on wall conditions and painting techniques was conducted and new processes and designs were developed. This paper examines the murals created for the 1984 Los Angeles Olympic Games, Judy Baca’s works, and the Balmy Alley Mural Environment project in San Francisco’s Mission District. Works by Las Mujeres Muralistas in Mission District, in particular, show case colorful patterns and the Latin American indigenous culture, exploring new interpretations of old icons and design. They challenged the stereotypical depictions of females and presented alternative visual languages that revised the male-centered mural aesthetics and elaborated on the aesthetics of Rasquachismo.

목적 : 본 연구는 편마비형 뇌성마비 아동에게 수정된 건측 상지 운동 제한 치료(Modified Constraint-Induced Movement Therapy)를 적용하여 환측 손 기능에 미치는 효과를 알아보기 위한 것이다. 연구방법 : 연구 대상자는 만 7세 2개월인 편마비형 뇌성마비 남자 아동으로 수정된 건측 상지 운동 제한 치료를 적용하여 손 기능에 미치는 효과를 알아보기 위해 개별실험 연구 방법인 ABA 디자인을 사용하였다. 기초선 자료는 수정된 건측 상지 운동 제한 치료를 시행하지 않고 4회기에 걸쳐 연구자가 Grooved Pegboard 검사와 장악력 검사를 사용하여 아동의 손 기능을 측정하였다. 치료 시기에는 총 10주 동안 하루 5시간씩 건측 손을 제한하고 주 3회 1시간씩 집중적인 상지 치료를 실시하고, 훈련 후 주 1회 손 기능을 측정하였다. 치료 이후 다시 기초선을 4회기 동안 측정하였다. 손 기능과 함께 일상생활에서 손을 얼마나 자주 사용하는지 보는 손사용의 빈도와 얼마나 잘 사용하는지 보는 손사용 숙련도는 치료를 실시하기 전과 치료가 종료된 이후 보호자와의 상담을 통해 각각 1회 측정하였다. 결과 : Grooved Pegboard 검사 결과 기초선 기간보다 치료 기간에 수행 시간이 감소되었으며 치료가 종결된 이후에도 그 효과가 유지되었다. 하지만 악력 검사에서는 기초선 기간과 치료 기간, 치료가 종결된 이후에 큰 변화를 보이지 않았다. 손사용의 빈도를 보는 Pediatric Motor Activity Log (PMAL) 검사에서는 치료 전보다 치료 후에 손사용의 횟수가 증가되었으나 손사용의 숙련도에서는 큰 변화가 없었다. 결론 : 본 연구에서 수정된 건측 상지 운동 제한 치료는 편마비형 뇌성마비 아동의 저하된 손 기능을 향상시키는 유용한 치료 방법임을 보여주었다. 추후 연구에서는 개별연구의 단점을 보완하기 위해 더 많은 뇌성마비 아동을 대상으로 수정된 건측 상지 운동 제한 치료의 효과를 알아보는 연구가 시행되어져야 하며, 치료 효과의 지속성에 대한 연구가 필요하다.

To develop effective training methods for strengthening a weakened quadriceps femoris muscle in hemiplegic patients, we examined the effects of maximal isometric contraction of the nonparalyzed knee joint on the electromyographic activities of the paralytic muscle. An electromyogram (EMG) was used to record the electromyographic activities of the paralytic quadriceps femoris muscle in 27 hemiplegic patients. The maximal isometric contraction was measured for each subject to normalize the electromyographic activities. The maximal isometric extension and flexion exercises were randomly conducted when the knee joint angles of the nonparalyzed knees were 0˚, 45˚, and 90˚. The patients were encouraged to maintain maximal isometric contractions in both knee joints during each measurement, and three measurements were taken. A one-minute rest interval was given between each measurement to minimize the effects of muscle fatigue. An average from the three values was taken as being the root mean square of the EMG and was recorded as being the maximal isometric contraction. The electromyographic activity obtained for each measurement was expressed as a percentage of the reference voluntary contraction, which was determined using the values obtained during the maximal isometric contraction. The results of this study are summarized as follows: First, when the knee joint angle of the nonparalyzed knee was 0˚, the electromyographic activities of the paralytic medial aspect of rectus femoris were related to measurement by a maximal isometric flexion exercise than by an extension exercise (p<.05). Second, when the knee joint angle of the nonparalyzed knee was 90˚, the electromyographic activities of the paralytic lateral aspect of rectus femoris were related to measurement by a maximal isometric flexion exercise than by an extension exercise (p<.05). The results show that myoelectrical activities of paralytic quardriceps were not related to measurement angles and exercise directions of the nonparalized knee joint. Studies on various indirect intervention to improve muscular strength of patients with nervous system disorders of the weakened muscle should be constantly conducted.

At the present time, Musculo-Skeletal Disorders breaks out and it is increased in a high speed. It is a serious problem for the labors and managements. People becoming greatly interested in it. It is caused by the labor intensity which is according to the work form, hours of labor, and the labors and the labor unions have a correct understanding in it, and the labor powers becoming older, and the change of divisional social environment which is latent. Before working do the simple preparation gymnastics or operate insensitive exercise remedy without scientific verification only in the present circumstances. Although operate the Work-related Musculo-Skeletal Disorders exercise remedy, it can not get a sufficient effectiveness. So the study develop one type of exercise remedy which are divided the upper limbs exercise remedy, the trunk exercise remedy, the lower limbs exercise remedy. It can be done without using any exercise equipments and regardless places. We should also enable the exercise remedy to be easily applied to workers who are in different circumstances. To use EMG to measure the burden of exercise remedy. By doing so, employees can easily do exercises and it will help to prevent and even can treat MSD. It is just the objective of the research.

Understanding awareness and wearing behavior of functional textiles for silver generation is expected to contribute to clothing products development to improve and maintain their health and marketing strategy fit for user characteristics. For empirical research, a survey was developed and the aged 50 and above were 332 respondents. The results of the study are as follows. First, the level of awareness for both comfort-oriented and health/safetyoriented functional fabrics in high health-conscious group was much higher than that in low health-conscious group. In number of wearing times, health body and high-conscious group wear comfort-oriented fabrics more frequently, while weak body group wear health/safety-oriented fabrics more often. The health-consciousness significantly influenced the possession of active sportswear with various functions. Second, the awareness of functional fabrics in exercise activities groups was much higher than that in exercise-conscious groups. High exercise activities group know more about the wet sensation-related fabrics and clothing materials for outdoor activities. Low exerciseconscious group put on health/comfort-oriented fabrics for casuals more frequent than functional fabrics for sportswear. High exercise activities group preferred to wear sportswear suitable for outdoor activities. The aged people have a lot of health/comfort-oriented functional casual wear appropriate for indoor activities regardless of exerciseconsciousness. However, the more they enjoy exercise activities the more they are interested in functional sportswear. Even though they were unconcerned with exercise, older people are interested in functional casual clothes. As a conclusion, the high interest in health and exuberant activities in silver generation arose the necessity of new multi-functional clothing products.

The aim of this study was to investigate effects of reaching distance on movement time and trunk kinematics in hemiplegic patients. Eight hemiplegic patients participated in this study. The independent variables were side (sound side vs. affected side) and target distance (70%, 90%, 110%, and 130% of upper limb). The dependent variables were movement time measured by pressure switch and trunk kinematics measured by motion analysis device. Two-way analysis of variance with repeated measures was used with Bonferroni post-hoc test. (1) There were significant main effects in side and reaching distance for movement time (p=.01, p=.02). Post-hoc test revealed that there was a significant difference between 110% and 130% of reaching distance (p=.01). (2) There was a significant main effect in side and reaching distance for trunk flexion (p=.01, p=.00). Post-hoc test revealed that there were significant differences in all pair-wise reaching distance comparison. (3) There was a significant side by target distance interaction for trunk rotation (p=.04). There was a significant main effect in target distance (p=.00). Post-hoc test revealed that there were significant differences between 70% and 110%, 70% and 130%, 90% and 110%, 90% and 130% of target distance. It was known that trunk flexion is used more than trunk rotation during reaching task in hemiplegic patients from the findings of this study. It is also recommended that reaching training is performed with limiting trunk movement within 90% of target distance whereas reaching training is performed incorporating with trunk movement beyond 90% of target distance in patients with hemiplegia.

The purpose of this study is to investigate the effects of improvement in the balance control ability of the elderly affected by Hansen's disease. We tried to compare the effects for the elderly affected by Hansen's disease with and without foot deformity. The subjects consisted of 19 patients 65 years old and older. They participated in a balance training program twice per week for 8 weeks. The following results were obtained from the training program: 1. There were significant improvements in static balance ability in one leg standing (OLS), dynamic balance ability in tandem walk (TW) and four square step (FSS) (p<.05). 2. There was a significant difference between patients with and without single-foot deformity in TW before the program (p<.05). After training, however, the difference became less significant. Also, there was not much difference between recipients with and without single-foot deformity in terms of OLS and FSS. The results of this study suggest that we need to provide training programs and rehabilitation services for the elderly affected by Hansen's disease suffering from nerve injury and disability. Furthermore, further research efforts should be made concerning rehabilitation to overcome various forms of disability.

The aim of this study was to investigate the effect of supporting surface instability to trunk and lower extremity muscle activities during bridging exercise combined with core-stabilization exercise. Thirty young healthy adults (15 males and 15 females) voluntarily participated in this study. Each subject was asked to perform bridging exercise combined with core-stabilization exercise on three different supporting surfaces (stable ground surface, the wooden balancing board, and the air cushion). The muscle activities were measured using surface electromyography (EMG) during performing exercise. To test statistical significance, one-way ANOVA with repeated measures was used with the significance level of .05. The findings of this study are summarized as follows. (1) There were significant differences in muscle activities on internal oblique, external oblique, gluteus medius, semitendinosus, biceps femoris, medial gastrocnemius and lateral gastrocnemius during exercise (p<.05). (2) The biceps femoris and lateral gastrocnemius showed significantly higher muscle activity on the wooden balancing board rather than on the ground, and semitendinosus, biceps femoris, medial gastrocnemius and lateral gastrocnemius showed significantly higher muscle activity on the air cushion rather than on the ground (p<.05). Therefore, it is concluded that muscle activities in the trunk and the lower limbs during bridging exercise combined with core-stabilization exercise was affected with instability of supporting surface. Further researches are needed to investigate the long term effect of bridging exercise on muscle activity with patient group.

This study aimed to compare 2 protocols recommended to patients with chronic cervical cord injury: each protocol included breathing exercises (inhalation-oriented or exhalation-oriented) and facilitation maneuver for the accessory respiratory muscles. Seventeen patients with chronic cervical cord injury volunteered to participate in this study, and we randomized these patients into 2 groups: the inhalation-oriented breathing exercise group (IOBEG) and exhalation-oriented breathing exercise group (EOBEG), consisting of 8 and 9 patients, respectively. Patients in the IOBEG performed inspiratory exercises using intermittent positive pressure breathing devices, while those in the EOBEG performed expiratory exercises using incentive spirometry. All exercises were performed by the subjects twice a day for 4 weeks, with each session lasting an average of 20 min. The outcomes were assessed on the basis of the pre- and post-treatment values of vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and FEV1/FVC. In the IOBEG, no significant differences were observed between the pre- and post-treatment values of any of the measured variables (p>.05); however, in the EOBEG, significant improvement was noted in the VC, FVC, FEV1 measured (p<.05) after the treatment. In addition, the rates of change in the values of VC, FVC, and FEV1 differed significantly between the 2 groups (p<.05). These findings suggest that the EOBEs can enhance respiratory function and are clinically feasible in patients with chronic cervical cord injury. Further studies will be undertaken to evaluate the clinical application of these findings.
