This retrospective study reports the effectiveness of Daoyin exercise therapy in a patient with lower back pain who suffered from idiopathic scoliosis. A patient was treated with Korean medicine containing Daoyin exercise therapy for 4 weeks. The patient was assessed for the numeral rating scale (NRS), Cobb's angle, correctability, and coronal balance. After treatment, the NRS of low back pain decreased from 9 to 1. The Cobb's angle of the thoracic curve decreased from 27.31° to 17.66°. The Cobb's angle of the lumbar curve decreased from 21.86° to 9.05°. Correctabililty was 35.34% in the thoracic curve and 58.60% in the lumbar curve. And coronal balance decreased from positive 32.80 mm to negative 3.20 mm. This study suggests that Daoyin exercise therapy could be effective therapeutic choice for lower back pain with idiopathic scoliosis.

Objective: The purpose of this study was to investigate the effect of 3-dimensional posture correction(3DPC) exercise program incorporating PNF respiratory muscle strengthening(RMS) exercise on spinal alignment and trunk expansion in patients with idiopathic scoliosis and the difference in intervention effect by type of idiopathic scoliosis. Design: Comparative study using paired t-test and analysis of variance measures. Methods: The subjects of this study were 5 men and 24 women diagnosed with idiopathic scoliosis with a Cobb angle greater than 10 degrees and less than 45 degrees. A 3DPC exercise program incorporating PNF RMS exercise was conducted twice a week for 1 hour per session for 6 weeks, and Cobb angle, Angle of trunk rotation, and trunk expansion were measured before and after the intervention. Results: After the intervention, Cobb angle and trunk rotation angle showed a statistically significant decrease, and trunk expansion showed a statistically significant increase. In the effect difference by type, there was a statistically significant difference in the angle of trunk rotation of the thoracic in 3C and Single Lumbar. Conclusions: In conclusion, it is thought that a 3DPC exercise program incorporating PNF RMS exercise can be effectively used in clinical practice to improve spinal alignment and trunk expansion in patients with idiopathic scoliosis.

앉은 자세를 장시간 유지하면 허리의 만곡에 변화가 오면서 통증이 발생하게 된다. 본 연구에서는 양반 앉은자세에서 SPINE-GUARD(허리 안정화 벨트) 착용이 허리뼈의 코브각과 허리통증 그리고 몸통 굽힘각도의 변화에 미치는 영향에 대해 알아보았다. 대상자 15명(남자)은 2주 동안 주 5회 매회 90분씩 벨트를 착용한 채로 영화를 감상하거나 강의를 들었다. 허리뼈의 코브각은 착용전 $48.36{\pm}14.57$에서 착용후 $28.09{\pm}11.63$로 유의한 감소를 보였다(p<0.05). 통증은 착용전 $4.53{\pm}2.36$이고, 착용후 $2.733{\pm}2.153$로 유의하게 감소하였다(p<0.05). 몸통의 굽힘각도 또한 착용전 $82.33{\pm}20.30$에서 착용 후 $70.2{\pm}19.43$로 유의한 감소를 보였다(p<0.05). 이것으로 보아 SPINE-GUARD의 착용은 허리뼈의 코브각 및 몸통굽힘각도의 변화 그리고 통증의 감소에 영향을 주는 것으로 사료된다.

Objective : The aims in the management of thoracolumbar spinal fractures are not only to restore vertebral column stability, but also to obtain acceptable alignment of the thoracolumbar junction (T-L junction) to prevent complications. However, insufficient surgical correction of the thoracolumbar spine would be likely to cause late progression of abnormal kyphosis. Therefore, we identified the surgical factors that affected unfavorable radiologic outcomes of the thoracolumbar spine after surgery. Methods : This study was conducted in a single institution from January 2007 to December 2013. A total of 98 patients with unstable thoracolumbar spine fracture were included. In these patients, fixation was done through transpedicular screws with rods by three surgical patterns. We reviewed digital radiographs and analyzed the images preoperatively and postoperatively during follow-up visits to compare the change of the thoracolumbar Cobb angle with radiologic parameters and clinical outcomes. The unfavorable radiologic group was defined as the patients who were measured as having greater than 20 degrees of thoracolumbar Cobb angle on the last follow-up, or who underwent kyphotic progression of thoracolumbar Cobb angle greater than 10 degrees from the immediate postoperative state to final follow-up, or who had overt instrument failure with/without additional surgery. We assessed the risk factors that affected the unfavorable radiologic outcomes. Results : We had 43 patients with unfavorable radiologic outcomes, including 35 abnormal thoracolumbar alignments and 14 instrumental failures with/without additional surgery. The multivariate logistic regression test showed that immediate postoperative T-L junction Cobb angle less than 10.5 degrees was a statistically significant risk factor, as well as the presence of osteoporosis (p=0.017 and 0.049, respectively). Conclusion : Insufficient correction of thoracolumbar kyphosis was considered to be a major factor of an unfavorable radiological outcome. The spinal surgeon should consider that having a T-L junction Cobb angle larger than 10.5 degrees immediately after surgery could result in an unfavorable radiological outcome, which is related to a poor clinical outcome.

본 연구는 Cobb종 및 Ross 308종 육계가 동물복지 사육환경에 따라 나타내는 대사체학적 변화를 연구하기 위하여 수행되었다. 일반농장과 동물복지농장(사육면적, 사육밀도, 암모니아 농도, 볏짚 등 제공)에 1일령의 Cobb종 및 Ross종 육계를 35일간 사육하고, 도계 후 가슴육과 다리육을 채취하여 분석에 이용하였다. 대사체 분석은 one-dimensional ¹H 핵자기공명분광법을 이용하였고, 직교부분최소자승판별분석(OPLS-DA)과 대사경로 분석을 함께 수행하였다. OPLS-DA 결과 육계 가슴육은 Ross종에 한하여 사육농장간 뚜렷한 구분이 가능하였다. 동물복지농장 유래 Ross종 육계 가슴육은 acetate, anserine, creatine, inosine monophosphate 함량이 일반농장 닭가슴육에 비해 유의적으로 높았다(P<0.05). 반면 육계 다리육은 OPLS-DA 결과 Cobb종 육계에서만 사육농장에 따른 구분이 뚜렷하게 나타났는데, glucose와 lactate를 포함한 5종의 대사체 함량은 동물복지농장에서 사육된 경우에 높았으나 7종의 유리아미노산을 포함한 9종의 대사체 함량은 낮았다(P<0.05). 대사경로 분석 결과 Ross종 육계 가슴육에서는 4종, Cobb종 육계 다리육에서는 glycolysis/gluconeogenesis를 포함한 20종의 대사경로에서 사육농장 간 유의적인 차이(P<0.05)가 나타났다. 동물복지농장에서 사육된 Ross종 육계 가슴육과 Cobb종 육계 다리육은 일반농장에서 사육된 경우와는 다른 대사체학적 특성을 나타냈으며, 특히 풍미 물질에의 뚜렷한 차이를 보여 관능적 특성에 영향을 미칠 수 있으리라 사료된다.

Scoliosis is a three-dimensional deformity caused by lateral curvature of the spine. The existing braces used to correct the posture were some drawbacks such as inconvenience, tightness as well as unfitness to wear. In this study, we devised a posture guidance system in order to monitor a posture continuously and lead to pose correctly and a new method fur measuring a Cobb's angle value in third dimension based on two 3-axis accelerometers. As a result, the correlation coefficients between desired and measured angles were and standard error between desired and measured angles were 0.99, 1.32(x-axis), 0.99 and 1.10(y-axis), respectively. The devised system showed good potential for the optimal posture guide and an early detection of scoliosis.

During the course of study on plant parasitic nematodes associated with medicinal herbs in Korea, high population of different stages of citrus nematode, Tylenchulus semipentrans was found in association with Pyrola japonia Klenze in Imsil, Chunbuk province. The second stage larvae and males were isolated from rhizosphere soil ; immature and mature females were detached from the roots of infested plants of Pyrola japonica. Besides citrus it has been reported to parasitize on roots of Syringa vulgaris, Diospyros lotus, olive, grapevine, and pear in different parts of the world. This is the first record of T. semipenetrans parasitized on a medicinal plant, Pyrola japonica.

The purpose of this paper is to estimate production function in the coastal fishing, especially long bag set net fishing and trap fishing using Cobb-Douglas production function with the three main variables: fishing quantity per tonage(WQFP), the number of working persons per tonage(WEMP), and the number of utilized fishing equipments per tonage(WEQU). The statistical results of such estimation reveal that fishing quantity per tonage can be expressed as a function of the number of working persons per tonage and the number of utilized fishing equipments per tonage. The estimated coefficients of WEMP and WEQU are statistically significant and also satisfy the requirements of Cobb-Douglas production function. This study also estimates marginal rate of technical substitution of labor in terms of capital (MRT $S_{LK}$ )in each long bag set net fishing and trap fishing. The resuits of this study show us that trap fishing has the technical characteristic of constant returns to scale(CRS) but long bag net fishing has that of decreassing returns to scale(DRS).
