수경재배시 양액 내 탄산정 처리를 통한 상추의 생육 및 생 리활성물질 변화를 조사하기 위해 네덜란드에서 시판되는 고 형 탄산정을 사용하였다. 실험은 무처리를 대조구로 하여 0.5 배, 1배, 2배 처리구로 구성하였다. 실험결과, 탄산정 처리 후 챔 버내 대기 CO2 농도는 처리 직후 2배 처리구에서 472.2μL·L -1 로 가장 높은 수치를 보였으며, 양액내 pH는 2배 처리구는 pH 6.03로 가장 많이 감소하였다. 이후 시간이 경과함에 따라 CO2 농도와 pH는 처리 전 수준으로 회복하는 모습을 나타냈 다. 상추의 엽폭과 엽면적은 탄산정 2배 처리시 17.1cm, 1067cm 2로 가장 큰 값을 나타내었으며 지상부 생체중, 건물 중은 0.5배 처리구에서 63.87g, 3.08g으로 가장 높게 나타났 다. 상추의 근장은 대조구에서 28.4cm로 가장 길었으나 처리 구들간에 지하부의 생체중, 건물중은 유의적인 차이를 나타 내지 않았다. 외관상 탄산정 처리에 의해 상추의 근장이 짧아 지고 곁뿌리가 많이 발생한 것이 관찰되었다. 또한 뿌리가 갈 색으로 약간 변하는 결과가 있었지만, 지상부 생육에는 부정 적인 영향을 미치지 않은 것으로 나타났다. 탄산정 처리에 의 한 상추의 생리활성물질을 분석한 결과 chlorogenic acid와 quercetin 두가지 물질이 검출되었으며 이를 정량분석한 결과 1배 처리구에서 chlrogenic acid는 대조구보다 249% 증가하 였지만 quercetin은 37% 감소한 결과를 나타냈다. 항산화 활 성을 나타내는 DPPH 라디컬 소거능을 비교한 결과 대조구와 0.5배 처리가 1배, 2배 처리보다 유의적으로 높은 값을 나타냈 다. 이를 통해 탄산정 처리가 수경재배 상추의 생육과 생리활 성물질을 증대에 효과가 있음을 제시한다.

Background: Stroke recovery is a long and complex process. Successful stroke recovery seems to be strongly associated with patients’ high motivation and committed participation. Patients’ motivation is a key determinant of successful rehabilitation outcomes, but it is difficult in defining and measuring. Patients’ participation is defined as the degree or extent to which subjects take part in rehabilitation activities and can be measured by observable behavior. Objects: The purpose of this study was to investigate the impact of patients’ level of participation in rehabilitation on functional outcomes in patients with stroke. Methods: Forty post-stroke inpatients participated in this study. The level of rehabilitation participation was measured by the Hopkins Rehabilitation Engagement Rating Scale (HRERS). Other measures used for the evaluation were the Rivermead Mobility Index (RMI) and Korean version of the Modified Barthel Index (K-MBI). Overall measurements were made at early intervention and late intervention. Spearman correlation and multiple regression were used to measure the relationships between HRERS, RMI, and K-MBI. Results: The correlation found between HRERS total scores at early intervention and RMI total scores of late intervention was above moderate (r = 0.607, p < 0.01). RMI total scores at early intervention (p < 0.000), HRERS total scores at early intervention (p < 0.001), and disease duration (p < 0.003) were significant predictors of RMI total scores at late intervention. Conclusion: The level of participation at early intervention was associated with improvement in mobility. The level of mobility at early intervention, disease duration, and patients’ participation at early intervention were important determinants of functional outcome. These findings suggest that patients’ participation should be encouraged in order to achieve successful stroke recovery.

Background: High string instrument (violin, viola) players are at high risk for developing musculoskeletal problems. In particular, a higher prevalence of shoulder problems has been reported. However, evidence of the effectiveness of therapeutic exercise for musicians with this condition is lacking until now. Objects: This case series study investigated the effect of a specific exercise program on shoulder pain, dysfunction, and posture of professional orchestral high string musicians. Methods: Five professional orchestral high string players with shoulder pain participated in this study. A six-week specific exercise program focus on scapular stability for shoulder pain consisted of scapular muscle exercise. Physical examinations for pain and dysfunction, posture were performed, were identified among all subjects before starting the exercise program. Results: The results revealed that shoulder pain decreased by 67.86% and the effect of pain on instrument play decreased by 63.33%. The shoulder pain and disability Index and the performing arts module-quick disability of the arm, shoulder and hand scale decreased by 71.72% and 51.61% respectively. The exercise program improved function and posture. Conclusion: A specific exercise program for high string players was effective in managing shoulder pain. This case series is intended to provide empirical data on the effectiveness of an exercise program aimed at assessing the effect of exercise on pain, dysfunction, and posture of professional orchestra musicians associated with specific instrument groups.

Background: In cerebral palsy (CP), parents’ quality of life and rearing attitude are considered possible factors that influence patients’ quality of life, function level, and performance in daily activities. Despite these facts, little attention has been given to demonstrate a relation between these factors. Objects: This study aimed to demonstrate the relationship between parents’ quality of life, functional level, and performance in daily activities, the quality of life of school-aged children with spastic CP. Methods: This study included 24 parents of school-aged children with spastic CP. The KIDSCREEN-52 and World Health Organization quality of life (WHOQOL)-BREF questionnaires (including physical, psychological, social, and environmental domains) were used as research tools to assess the quality-of-life profiles of the children with spastic CP and those of their parents, respectively. In addition, the function levels and performance in daily activities of the children with CP were assessed by using the gross motor function measure (GMFM) and modified Barthel index (MBI). Correlation and multiple regression analyses were performed to clarify the determinants of the quality of life of the children with CP. Results: The KIDSCREEN-52 score correlated with the total score (r=.735, p<.01) and all domains of the WHOQOL-BREF questionnaire (physical: r=.542, p<.01; psychological: r=.690, p<.01; social: r=.568, p<.01; and environmental: r=.783, p<.01). In addition, significant correlation was found between the KIDSCREEN-52 and MBI scores (r=.411, p<.05), and between the MBI and GMFM scores (r=.427, p<.05). After controlling for age, gender, paralytic type, GMFM, and MBI, the WHOQOL-BREF score (R2=.621), particularly in the environmental domain (R2=.699), remained independently related to the quality of life of the children. Conclusion: These findings suggest that the quality of life of school-aged children with spastic CP can be influenced by the quality of life of their parents. This study provides useful information for future studies to investigate the quality of life of children with CP

Background: In the treatment of temporomandibular joint (TMJ) disorder, the goals of traditional physical therapy are not only to reduce the inflammatory process leading to pain, but also to decrease joint overload and muscle hyperactivity. To achieve those goals, physical therapists generally use a photo-therapy, joint mobilization, and massage. Objects: To examine the impact of an unloading technique using non-elastic taping on the pain, opening mouth, functional level, and quality of life in patients with TMJ disorder. Method: Twenty patients with TMJ disorder were included in this study and randomly divided into the experimental (n1=10), and control (n2=10) groups. Traditional physical therapy including massage and stretching for 30 min was performed in both groups. Non-elastic taping was performed in the experimental group after traditional physical therapy, and they were recommended to keep the tape attached for 12 hours. Outcomes for pain, functional level, and quality of life were measured using a survey. The opening mouth was measured using a general ruler. Result: Significant differences were observed in the pain level, opening mouth, functional level, and quality of life after the intervention and on follow-up in both groups. However, we found that while the levels of all parameters were maintained throughout the follow-up period in the experimental group, the functional status level was not maintained throughout the follow-up period in the control group. Conclusion: Our unloading technique using non-elastic tape results comparable to those achieved by traditional physical therapy in the treatment of TMJ. However, the unloading taping method using non-elastic tape is more effective than traditional physical therapy in maintaining the impact of intervention

The purpose of this study was to examine the outdoor sportswear purchase behavior, outdoorwear sportswear brand preference, functional fabric awareness, and benefits sought. The research was performed through in-depth interview during February to March 2011. Data were collected from 10 consumers who had purchased outdoor sportswear and experienced camping in 6 months. First, the results from study showed that functionality/comfortability, design, color, and brand name were important factors in selecting outdoor sportswear. Offline stores were the main place to purchase, however, internet shopping mall and portal online community were another shopping channel as well. Second, respondents preferred imported outdoor sportswear brand to national brand. According to the study, the respondents trusted the imported outdoor sportswear quality based on the brand name, value, and brand history more than national brand. Third, consumers who had low functional fabric awareness were more likely to evaluate apparel products based on the brand name. Knowledge levels for textile functions were high in elastic, UV protection, air permeable, and antibacterial properties. The essential features for camping were water absorbing and quick dry, water resistance, wind proof, UV protection, and fire retardant properties. Finally the results showed that there were two sportswear benefit soughts: functionality and status ostentation.

It is important to find the effective position for cough and sputum clearance in respiratory physical therapy. The purpose of this study was to compare the changes in peak expiratory flow (PEF), forced expiratory volume in 1 second (FEV1), and peak cough flow (PCF) related to functional level and measurement position in patients with Duchenne muscular dystrophy. Twenty one subjects were classified into three functional levels, and measurements was undertaken in three different measurement positions (upright sitting, 45˚ reclining and supine). Vitalograph PEF/FEV DIARY was used to measure PEF and FEV1, and Ferraris Pocket Peak was used to measure PCF. Mixed two-way analysis of variance and Bonferroni post-hoc test were used for statistical analysis. The results of the study were as follows: 1) Significant main effects for measurement position were found. 2) PEF was the highest in upright sitting, followed by 45˚ reclining, and supine in order. 3)FEV1 in upright sitting and 45˚ reclining were significantly greater compared with that in supine. 4) PCF in upright sitting and 45˚ reclining were significantly greater compared with that in supine. 5) No significant main effects for functional level were found in PEF, FEV1, and PCF. 6) No significant functional level by measurement position interactions were found in PEF, FEV1, and PCF. Therefore, it is concluded that upright sitting and 45˚ degree reclining positions are recommended for effective cough and sputum clearance.

국내 4대강에 설치된 다기능보는 하천을 횡단하는 수공구조물로써 고정보와 가동보로 구분되어 설치되었으며, 각 다기능 보의 수문운영 방식에 따라 유량이 변화하여 하상변동 및 유사이동 형태의 변화 가능성이 있다. 본 연구에서는 다기능보의 수문운영에 따른 장기 하상변동을 금강유역을 중심으로 연구하였다. 연구결과, 금강에서는 다기능보의 설치 및 수문운영 시나리오에 따라서 최심하상고의 변화가 연평균하상고의 변화에 비해서 상대적으로 큰 것으로 나타났다. 최심하상고의 하상저하는 최대 2.79 m, 하상상승은 최대 1.90 m까지 발생하는 것으로 나타났으며, 연평균하상고의 하상저하는 최대 2.16 m, 하상상승은 최대 1.24 m까지 발생하는 것으로 나타났다. 또한 하상변동에 따른 홍수위 분석 결과, 다기능보 설치 후에 홍수위가 대부분 상승하는 것으로 나타났으며, 최대 2.23 m까지 상승하는 것으로 나타났다. 이러한 결과로 인해서 제방의 여유고를 상회하는 홍수위가 발생할 가능성이 있기 때문에, 하천의 유사관리 및 하천계획수립을 함에 있어서 다기능보의 수문운영을 고려해야 한다고 판단된다. 또한 본 연구결과는 향후 하천계획을 수립함에 있어서 종단적 하도관리 및 안정하상 채택 등을 위해서 기초자료로 활용될 수 있을 것으로 본다.

Soybean quality is determined based on protein content, lipid content and fatty acid composition, and several functional components including isoflavones, anthocyanins and functional activity. Because the level of each component changes during seed development, it is necessary to know the concentration of quality-related components in developing seeds. Little is known of the pattern of changes in quality-related components. Seeds from field-grown soybean was harvest from the R6 stage to the R8 stage in 2004. Seed characteristics and the level of nutritional components were examined. Seed moisture content was dropped rapidly after the R7 stage in the tested varieties. Seed growth rate was the highest from the beginning of the R6 stage to the mid-R6 stage. Chlorophyll content was decreased rapidly in pods and seeds. However, seed growth period from the R6~;to~;R8 was 35 days. The crude protein content was. increased dramatically between 63 DAF and 70 DAF and then increased slightly. The pattern of isoflavone accumulation was nearly similar to that of seed weight increase. From the late R6 stage to the R7 , the accumulation rate was higher as compared to other stages. The angiotensin inhibitory activity was increased according to seed development from 63 (R6 ) to 84 DAF (R8 ). The difference of inhibitory activity in heated soybean powder, however, was not great among stages. The inhibitory activity was affected by heating treatment. The most effective heating time was 10 min. Excessive heating longer than 30 min resulted in a lowered inhibitory activity of soybean on ACE
