기후변화와 불투수지역의 증가로 인하여 하천 유량의 변동성은 점차 커지고 있다. 이에 따라 유량에 영향을 받는 하천환경과 다양한 생태계는 큰 영향을 받고 있음에 유량 관리가 매우 중요시 되어지고 있다. 하천 유량은 빗물이 지표면에 떨어져 직접하천으로 흐르는 지표유출과 지표면하의 암반층으로 침투되어 지하수가 되고 시간의 흐름에 따라 지표로 흘러나오는 기저유출로 구성되어 있다. 기저유출은 땅속에서 흐르기 때문에 흐름이 느리다. 이에 따라 강우가 발생하지 않을 시에 하천유량의 대부분을 차지하고 있다. 따라서 기저유출의 관리는 수자원의 관리에 매우 중요할 것이다. 국내외에서도 기저유출의 관리를 위한 연구가 필요하며 지표수-지하수의 연계관리를 위한 명확한 조명이 필요한 시기이다. 본 연구에서는 국내 기저유출의 분포와 지하수 의존형 수생태계가 미치는 영향에 대해서 분석하였다. 기저유출의 분리는 최근 많은 연구가 수행되어져 왔고 다양한 방법이 개발되었다. 일반적으로 시계열 유량자료를 통해 기저유출을 산정한다. 기저유출의 산정을 위해 두 가지 유량 데이터를 이용하였다. 검보정된 수문모형을 통한 데이터와 국내에 존재하는 관측데이터를 이용하여 지표유출과 기저유출을 분리하여 유역의 기저유출지표를 산정하였다. 기저유출지표는 총 유출량과 기저유출과의 비로 산정되는 유역의 특성을 나타내는 지표이다. 기저유출과 수생태계의 관계를 분석하기 위해 환경부에서 수행하는 네 가지 수생태건강성지수와 기저유출지표와의 상관성을 분석하였다. 수생태건강성지수는 부착돌말류, 저서성 대형무척추동물, 어류, 서식 및 수변환경으로 구성되었다. 기저유출 산정과 수생태계와의 분석은 낙동강유역을 대상으로 수행하였다. 낙동강유역의 기저유출을 산정하여 기저유출지표를 산정한 결과 0.4이상의 값을 나타냈다. 이는 하천의 유량 중 약 40%가 기저유출에 의존한다는 의미이다. 또한 월별 기저유출지표를 산정한 결과 강수가 적은 봄과 겨울철의 경우 0.7이상을 나타냈다. 특히 1월달의 경우 0.9이상을 나타내 겨울철 대부분의 하천 유량은 기저유출에 의존한다. 산정된 기저유출지표와 네 가지 수생태건강성지수의 상관성 분석을 수행하였다. 분석결과 저서성 대형무척추동물과의 상관성을 나타냈고 나머지에서는 상관성을 나타내고 있지 않았다. 하지만 이는 아직 국내에서 수생태계의 건강성 조사와 평가가 이루어진지 얼마 되지 않았기 때문으로 판단된다. 본 연구결과를 바탕으로 기저유출관리 방안의 정책적인 도입과 연구의 시발점이 될 것이다.

Objectives We conducted an online survey to understand the current status of Korean Medicine clinical practice related to carpal tunnel syndrome (CTS) to develop the CTS Korean Medicine Clinical Practice Guidelines (CPG). Methods A thoroughly reviewed questionnaire was distributed by e-mail to 21,719 Korean Medicine doctors between March 26 and April 30, 2021. All raw data were arranged and analyzed systematically. Results The response rate among the doctors was 4%. Of the respondents, 82.1% responded that it is necessary to develop the CTS Korean Medicine CPG. We also obtained data related to the specific diagnosis, treatment, and prognosis management methods used at various treatment sites for patients with CTS. Conclusions This online survey will be helpful in developing the CTS CPG, which will contribute to the standardization of guidelines and improvements in the reliability of Korean Medicine. Our findings will provide valuable data and resources for future clinical studies on CTS.

Objectives The objective of this study was to evaluate the effect of chuna manual therapy for rhinitis. Methods We performed a literature search using ten electronic databases (PubMed, Embase, Cochrane Library, Chinese Academic Journals(CAJ), Research Information Sharing Service(RISS), Dbpia, National Digital Science Library(NDSL), Koreanstudies Information Service System(KISS), Korean Medical database(KMbase), and Oriental Medicine Advanced Searching Integrated System(OASIS)) and two academic journals up to the end of April 2021. We included randomized controlled trials (RCTs) which appraised the effect of chuna manual therapy (CMT) in the treatment of rhinitis. The risk of bias was evaluated from the Cochrane Risk of Bias tool. Results 4 appropriate RCTs were included and analyzed. The efficacy rate of the CMT group was statistically higher compared to the control group treated with medicine[RR 1.14 (95%CI 1.06 1.22), P<0.01]. Conclusions Based on results, CMT could be effective in rhinitis. However, evidence were limited due to small number of studies, lack of well-designed RCT and regional bias. Further well-designed research should be required to obtain stronger evidence.

Objectives This systematic review aimed to provide evidence for the effectiveness and safety of Chuna manual therapy (CMT) for carpal tunnel syndrome (CTS). Methods We searched 12 electronic databases (PubMed, Ovid-MEDLINE, EMBASE, The Cochrane Library, CNKI, CiNii, ScienceON, KMbase, KISS, OASIS, KMTANK, and RISS) up to the end of October 2021. We only included randomized controlled trials (RCTs) investigating CMT for the treatment of CTS. The methodological quality of the included RCTs was evaluated using the Cochrane Risk of Bias Tool 1.0. Results Six RCTs were eligible for inclusion in our study. A meta-analysis of four studies demonstrated positive results for the use of CMT when used in conjunction with Korean medicine treatment compared to those for Western conservative treatment for CTS. Conjunction treatment significantly improved the total efficacy rate compared to conservative treatment alone (P=0.0007, n=4). Conclusions There is reliable evidence for the use of CMT in treating CTS based on a published meta-analysis. To measure only the effect of Chuna, an experimental group should be designed with Chuna alone to evaluate its effectiveness. However, it should be noted that the studies included in this systematic review were heterogeneous and of low quality, thus warranting further investigation using well-designed RCTs.

Facet joint arthrosis is a progressive degenerative disease that is frequently associated with other spinal degenerative disorders such as degenerative disc disease or spinal stenosis. Lumbar facet joint arthrosis can induce pain in the proximal lower extremities. However, symptoms and imaging findings of "facet joint syndrome" are not specific as they mimic the pain from herniated discs or nerve root compression. Currently, evidence for therapeutic intra-articular lumbar facet joint injections is still considered low, with a weak recommendation strength. Nevertheless, some studies have reported therapeutic effectiveness of facet joint injections. Moreover, the use of therapeutic facet joint injections in clinical practice has increased. This review article includes opinions based on the authors' experience with facet joint injections. This review primarily aimed to investigate the efficacy of lumbar facet joint injections and consider their associated safety aspects.

Campyloderes macquariae Johnston, 1983 is reported from South Korea. Specimens were obtained from the washings of subtidal sediments, holdfasts of macroalgae, and various invertebrates. This is the first record for genus Campy-loderes from the North Pacific. Affinities with its congeners and the variability within species are discussed, with the confirmation of several morphological details by scanning electron microscopy.

A traumatic spinal subdural hematoma is a rare condition, and only nine cases have been reported until now. We report a rare case of concomitant intracranial hemorrhage and spinal subdural hematoma with a review of the literature. A 45-year-old man was referred to our institute after being stroke by a car. He complained of nausea, headache, back pain, and bilateral sciatica. Brain computed tomography and lumbar spine magnetic resonance images revealed both an intracerbral hemorrhage and a subdural hematoma in the L4 to S1 level. After performing a lumbar spinal puncture and draining the hemorrhagic cerebrospinal fluid (CSF), the intracranial and spinal hematomas were resolved completely without any neruologic deficits.

Eight specimens (330.2~431.3 mm TL) of the family Zoarcidae were collected from the costal waters of the Byeonsanbando, Yellow Sea, Korea. They were identified as a Zoarces elongatus Kner based on the following characters: a dorsal fin with 14~16 notch-shaped spinous rays, irregular 13~16 dark spots in a row along the median body and 126~132 vertebrae. We proposed a new Korean name, 'Mu-jeom-deung-ga-si-chi', for the species.

Craniovertebral junction (CVJ) tuberculosis is a rare disease, and potentially fatal due to the risk of atlantoaxial dislocation. The disease usually accompanies a retropharyngeal cold abscess, which can cause subsequential otolaryngologic symptoms such asdysphagia, odynophagia, or airway obstruction. Such a patient must be handled with great care to avoid a disaster. The disease is diagnosed with microbiological or other laboratory tests on the pus collected through puncture and aspiration, which will need otolaryngologic skills. For treatment, otolaryngologists play an important role by doing incision and drainage of the retropharyngeal abscess, or by attending the transoral vertebra surgery as partners with spine surgeons who will manage the CVJ lesions and ensure the craniocervical stability.
