Purpose: A cost effective tool for the clinical measurement of trunk reposition sense is clearly needed. This study was to analyze intrarater and interrater Reliability of trunk repositioning error (TRE) test which assesses trunk position sense using a portable digital inclinometer. Methods: Twenty four normal healthy subjects were recruited. TRE was measured using a portable digital inclinometer. A digital inclinometer (Acumar-ACU360; Lafayetter Instrument) with precision to $1^{\circ}$ was placed on skin over the spinous process from first to second thoracic vertebra (T1-T2) and secured with double-sided tape. TRE test during sitting forward and lateral flexion movement was assessed. When they reached a point approximately 50% of full trunk flexion range, the examiner instructed the subjects to stop and told them. This was the target position that they should try to reproduce exactly. Each subject performed six trials. Results: ICC (2,1) for intrarater reliability (with-day and between-day) of TRE test in sagittal and frontal plane of movement was 0.75 and 0.78 (excellent reliability). Interrater reliability was 0.66 in sagittal and 0.64, frontal plane (fair to good reliability). However, there were poor correlations between an average of TRE test in sagittal and frontal plane. Conclusion: TRE test using a portable digital inclinometer demonstrated good to excellent reliability. The device may be a cost effective clinical measurement for trunk reposition sense measurement.

Purpose This study aimed to investigate the effect of facilitating shoulder protraction on upper limb function, static and dynamic balance in hemiplegic patients with stroke. Methods A total of 23 patients were randomly allocated into either the study group (SG) of 13 patients or the control group (CG) of 10 patients, respectively. All subjects in the two groups were trained for 30 minutes a session, 10 sessions for 2 weeks. Manual Function Test (MFT) for the upper limb function, Functional Reaching Test (FRT) and Timed Up and Go Test (TUG) for the balance, and the 2D video analysis program (Dartfish ProSuite 9.0) for the trunk displacement and elbow extension angles during reaching to grasping were used for the outcome measures. Results In the result of the MFT and TUG, there were significantly improvements in the SG, within and between the groups. FRT was significantly increased in distances in both groups, within and between the groups. During the arm reaching to the task for grasping on the table, elbow extension angle was significantly increased and trunk forward displacement was decreased in the SG. Conclusion This study demonstrated that facilitation of shoulder protraction showed significant improvements in function of the affected upper limb and postural control by decreasing compensatory trunk strategies during arm reaching.

Purpose Paralysis of abdominal muscles is the main cause of respiratory dysfunctions in patients with cervical spinal cord lesion. Activation of the abdominal muscles using functional electrical stimulation (FES) improved respiratory function in these patients. However, studies evaluating the effect of assisted respiratory training using FES on abdominal muscles in tetraplegia with cervical spinal cord lesion are sparse. Methods FES was applied to the abdominal muscles. Respiratory function tests were performed before and after therapy, and at 2 weeks follow-up. In addition to chest physical therapy, patients received training to improve respiratory function (experimental group) or training for increasing muscle tone of lower limb (control group). Both groups received 10 hours of additional training on FES; 30 minutes a day, 5 times a week, for 4 weeks. Results After 4-week therapy, both groups displayed significant improvement in their MIC, FVC, FEV1, assisted PCF, and unassisted PCF (p<0.05). At the follow-up test (2 weeks after 4-week therapy), the experimental group was improved cough capacity (APCF and UPCF), compared with in the control group (p<0.05). Conclusion Our results suggest that, in addition to chest physical therapy, FES over the abdominal muscles aimed at improving respiratory function and cough capacity in cervical spinal cord injury with tetraplegia have beneficial effects on maintaining and developing a cough function.

Purpose The purpose of this study was to investigate the effects of trunk facilitation based on the Bobath concept on trunk alignment and weight distribution on standing in patients with stroke. Methods This study was designed as an assessor-blinded, randomized controlled trial. A total of 27 stroke patients were randomly allocated into the two groups: trunk facilitation group (n=14), and conventional physiotherapy group (n=13). All the patients were trained for 30 minutes a day, 5 times a week for 5 weeks. Results The mean age of the patients in the study group was 50.29 years and that of the control group was 52.54 years. In the results of the trunk alignments, there were significant decreases in spinal length(VP-DM), forward trunk inclination in sagittal plane, trunk imbalance in frontal plane and thoracic angle in the trunk facilitation group(p<0.05). But, there was no difference between the two groups. There were significant increases in backward weight distribution and covered area on affected foot(p<0.05). There was a significant decrease in the forefoot pressure of the unaffected limb in standing(p<0.05). Between the two groups, there were significant difference in the AP weight distribution, covered area on the affected foot, and forefoot pressure on the unaffected foot(p<0.05). Conclusion The study was demonstrated that the trunk facilitation based on the Bobath concept showed significantly recovery of midline orientation in standing posture.

장우성,김동중,김진현,한국남,최창휴,김웅한 대한흉부외과학회 2005 Journal of Chest Surgery (J Chest Surg) Vol.38 No.5

It is very difficult to choose the ideal valved conduit used in right ventricle outflow reconstruction in child. We can use the cryopreserved homograft but there is a limit of appplication because of its difficulties in the size matching and supply capacity. The ShelhighⓇ porcine-valved conduit is commercially available and used as an alternative choice in these days. We report two cases of early Shelhigh conduit failure in right ventricular outflow tract after Ross operation in congenital aortic stenosis. 소아의 우심실-폐동맥 연결에 이용되는 판막 도관에는 여러가지가 있다. 현재까지 동종이식편(homograft) 판막도관이 가장 이상적인 것으로 알려져 있으나 유아에서는 크기 및 공급에 제한점이 있다. 최근에는 다양한 크기의 이종이식편(xenograft) 판막도관이 상업적으로 이용 가능하여 하나의 대안으로 여겨지지만 이역시 많은 문제점을 가지고 있다. 선천성 대동맥판 협착증으로 Ross 수술을 시행한 2예에서 우심실 유출로 도관으로 이용한 Shelhigh porcine-valved conduit (SPVC)에 심한 가성내막껍질형성(Pseudointimal peel formation)으로 조기에 도관 교환이 필요했기에 문헌고찰과 함께 보고하는 바이다.

오늘날 제품의 특성을 소비자에게 자세히 인지시키는 것은 쉽지 않은 일이며, 소비자 역시 상품과 관련된 전문지식을 가지고 있지 않아 제품 선택에 많은 어려움을 겪고 있다. 이러한 상황에서 지방자치단체들은 해당 지역에서 생산되는 제품이 소비자에게 신뢰를 주고 차별화된 이미지를 형성하도록하기 위하여 지역공동브랜드를 구축하고 홍보하는데 적극 노력하고 있다. 지역공동브랜드는 지역의 대표 상품에 대해 하나의 통합브랜드를 사용하는 형태로, 운영 빈도가 꾸준히 증가하고 있으며, 지역 특산물의 경쟁력 제고 및 지역 경제 활성화, 세수확대 , 고용창출 등 많은 긍정적 영향을 미치고 있다. 그러나 지방자치단체들의 지역브랜드 특히 지역공동브랜드에 대한 관심과 지원에 비해 아직 많은 연구들이 이루어지지 못한 실정이다. 이에 본 연구에서는 지방자치단체의 지역공동브랜드가 소비자의 제품구매행태에 어떠한 영향을 미치는지를 알아보고자 한다. 즉, 지역공동브랜드의 유무와 유형(지방자치단체장 인증브랜드 vs. 지역상품 공동브랜드)에 따른 소비자들의 지역상품에 대한 태도와 구매의도의 관계를 고찰하고자 한다. 더불어 소비자의 개인적 특성 중 지역상품 구매와 관련하여 중요한 영향을 미칠 것으로 예상되는 지역공동브랜드에 대한 신뢰도, 애향심, 그리고 지역공동브랜드에 대한 사전지식에 따른 지역공동브랜드와 소비자행동의 관계를 살펴보고자 한다. 본 연구결과는 지방자치단체의 지역상품에 대한 브랜드 도입과 관련한 전략수립에 유용한 정보를 제공함과 동시에 공동브랜드에 대한 신뢰도와 사전지식, 애향심 정도에 따른 소비자의 차별적 관리와 관련해서 의미 있는 시사점을 제공할 것이다. In order to predominate over competition between regions and to increase local residents' income, in the era of local autonomy, this study examined the influence of local co-brands on consumers' purchase intention and attitude towards the regional products. Also this study examined how their purchase intention and attitude can be moderated in accordance with the level of reliability, local patriotism, and prior knowledge about the products, which are expected to have great influence on purchase of regional products. In the results of the empirical analysis, consumers showed more positive product attitude and purchase intention towards regional products attached with local co-brands, than products without them. Regarding the type of local co-brands(local government certification brand vs. regional private co-brand), consumers showed more positive attitude and purchase intention towards regional products with the local government certification brands than the regional private co-brands. In the influence of attaching the local co-brands on product attitude and purchase intention, the level of reliability, local patriotism, and prior knowledge all showed significant moderating effects, only except the case of prior knowledge on product attitude. While, in the influence of the type of local co-brands(local government certification brand vs. regional private co-brand), all the moderating effects of the level of reliability, local patriotismand prior knowledgewas not significant

본 연구는 대표적인 내수면 어류인 철갑상어과 어류의 효율적 이용을 위하여 해수순치산 철갑상어의 식품성분 특성에 대하여 살펴보았고, 아울러 담수양식산 철갑상어의 식품성분 특성과도 비교 검토하였다. 해수순치산 철갑상어의 일반성분 함량은 수분이 78.0%, 조단백질이 19.1%, 조지방이 1.5%, 회분이 1.1%였고, 이는 담수양식산 철갑상어에 비하여 수분의 경우 낮았으나, 조단백질, 조지방, 회분의 경우 높았다. 해수순치산 및 담수양식산 철갑상어 근육의 에너지는 2종이 모두 100 ㎉/100 g 이하였다. 해수순치산 철갑상어의 헌터색조는 명도가 64.2, 적색도가 4.4, 황색도가 14.1이었고, 이는 담수양식산 철갑상어에 비하여 명도와 황색도의 경우 낮았고, 적색도의 경우 높았다. 해수순치산과 담수양식산 간에 경도는 유의적인 차이가 없었다(P>0.05). 해수순치산 철갑상어의 냄새 강도와 총 아미노산 함량은 각각 436.0 level 및 19.0 g/100 g이었고, 이는 담수양식산 철갑상어에 비하여 두 성분이 모두 높았다. 해수순치산 및 담수양식산 철갑상어 모두 주요 아미노산은 aspartic acid, glutamic acid, leucine 및 lysine이었다. 해수순치산 및 담수양식산 철갑상어 간에 무기질 함량과 지방산 조성은 유사하였다. 이상의 결과로 미루어 보아 해수순치산 및 담수양식산 철갑상어 간의 관능적 및 영양적 특성은 차이가 있는 것으로 나타났다. This study was conducted to compare the sensory and nutritional characteristics between sea-reared and freshwater sturgeons Acipenser oxyrinchus. The proximate composition of sea-reared sturgeon was 78.0% moisture, 19.1% crude protein, 1.5% crude lipid, and 1.1% ash. Thus, moisture content was lower while crude protein, crude lipid, and ash contents were higher than those of freshwater sturgeon. Regardless of culture methods, energy content of sturgeon muscle was 88.5∼95.9 ㎉/100 g. The Hunter color values of sea-reared sturgeon were 64.2 for lightness, 4.4 for redness, and 14.1 for yellowness. Thus, lightness and yellowness were lower while redness was higher than those of freshwater sturgeon. The hardness of sea-reared sturgeon was 4.1 ㎏/㎠, which was not significantly different (P<0.05) than that of freshwater sturgeon. The odor intensity of sea-reared sturgeon was 436.0 level, which was higher than that of freshwater sturgeon. The total amino acid content of sea-reared sturgeon was 19.0 g/100 g, which was higher than that of freshwater sturgeon. The major amino acids of the sturgeons were aspartic acid, glutamic acid, leucine, and lysine. The mineral contents and fatty acid composition of sea-reared sturgeon were similar to those of freshwater sturgeon. The results suggest that there were slight differences in sensory and nutritional characteristics between sea-reared and freshwater sturgeons.
