두피에서 재발한 융기성 피부섬유육종의 MR영상: 증례 보고
조준,김미영,노홍기 대한자기공명의과학회 2006 Investigative Magnetic Resonance Imaging Vol.10 No.2
A 48-year-old man presented with a dermatofibrosarcoma protuberans (DFSP) of the scalp associated with local recurrence. Axial T1- and T2-weighted images demonstrated a well-circumscribed hypointense and intermediate hyperintense mass in the skin and subcutaneous layer of the scalp, respectively. Contrast-enhanced T1-weighted images showed the strongly enhanced mass invasion to the skin, subcutaneous layer and adjacent galeal layer. Scalp DFSP is very uncommon but is an aggressive tumor, so MR imaging diagnosis of the extent of the lesion to underlying structures, and initial wide local resection is important to prevent recurrence.

Predictive mathematical models were developed for predicting the kinetics of growth of Listeria monocytogenes in smoked salmon, which is the popular ready-to-eat foods in the world, as a function of temperature (4, 10, 20 and 30℃). At these storage temperature, the primary growth curve fit well (r² = 0.989~0.996) to a Gompertz equation to obtain specific growth rate (SGR) and lag time (LT). The Polynomial model for natural logarithm transformation of the SGR and LT as a function of temperature was obtained by nonlinear regression (Prism, version 4.0,GraphPad Software). Results indicate L. monocytogenes growth was affected by temperature mainly, and SGR model equation is 365.3-31.94*Temperature+0.6661*Temperature^2 and LT model equation is 0.1162-0.01674*Temperature+0.0009303*Temperature^2. As storage temperature decreased 30℃ to 4℃, SGR decreased and LT increased respectively. Polynomial model was identified as appropriate secondary model for SGR and LT on the basis of most statistical indices such as bias factor (1.01 by SGR, 1.55 by LT) and accuracy factor (1.03 by SGR, 1.58 by LT).

위축뇌탈출증(atrectic cephalocele)은 중앙의 두피하부에 있는 피부로 덮힌 병변으로서 수막과 아교세포나 중추 신경계 조직의 잔유물들을 포함한다. 수직동이 없거나 잔유물로 남아있는 경우 낫형동(falcin sinus)이 다시 관류하게 되어 정맥의 배출이 가능하게 된다. 위축된 뇌탈출증 또는 지속적인 낫형동은 소아에서 주로 기술되어 왔으며, 성인에서는 매우 드문 병변이다. 저자들은 성인에서 자연퇴화된 위축뇌탈출증이 지속적인 낫형동을 동반한 매우 드문 증례를 보고하고자 하며 MR영상과 MR정맥조영술은 정확한 해부학적 묘사와 진단에 유용하였다.

The authors aimed to analyze the quality improvement efficiency of wound dressing with 2-octyl cyanoacrylate(2-OCA) in stereotactic image guided linear or sigmoid incisions in a cohort of consecutive craniotomy patients, and to compare clinical results with those of iodine-dressing and silk sutured patients underwent conventional craniotomy surgery with large pedicle flap incisions without stereotactic guidance. In methods, 26 patients were involved as the study group at one hospital. We retrospectively compared their results with those of 38 consecutive control patients at the same unit. The suggested new medical material, 2-octyl cyanoacrylate(2-OCA), resultantly decreased or prevented the contaminated fluid influx from scalp outside. The mean infection rate for the control group (7.89%) was relatively higher than that of the study group (3.85%). In addition, the use of stereotactic image guided craniotomy was significant to reduce operation time, to simplify operative procedures and to decrease potential risk factors.攀†교신저자 mykim@inha.ac.kr ※ 이 연구는 2004년도 건국대학교 학술진흥연구비 지원으로 수행되었음.攀攀

The purpose of this study is to examine the mediating effect of food insecurity on the relationship between the income classes and health of the elderly. To test the study hypothesis, multiple regression analyses and sobel-tests were used for 1,548 elderly persons aged 65 years or older. According to the results of analyses, first, a partial mediating effect of health was found in the relationship between the income classes experienced by the elderly and the health of the elderly. Based on the foregoing, theoretical grounds for social welfare intervention to manage the health of the elderly were presented.

Vertebrobasilar junction entrapment due to a clivus fracture is a rare clinical observation. The present case report describes a 54-yr-old man who sustained a major craniofacial injury. The patient displayed a stuporous mental state (Glasgow Coma Scale [GCS]=8) and left hemiparesis (Grade 3). The initial computed tomography (CT) scan revealed a right subdural hemorrhage in the frontotemporal region, with a midline shift and longitudinal clival fracture. A decompressive craniectomy with removal of the hematoma was performed. Two days after surgery, a follow-up CT scan showed cerebellar and brain stem infarction, and a CT angiogram revealed occlusion of the left vertebral artery and entrapment of vertebrobasilar junction by the clival fracture. A decompressive suboccipital craniectomy was performed and the patient gradually recovered. This appears to be a rare case of traumatic vertebrobasilar junction entrapment due to a longitudinal clival fracture, including a cerebellar infarction caused by a left vertebral artery occlusion. A literature review is provided.

The purpose of this study is to examine the effect of client violence perceived by the public welfare workers on burnout and the mediating effect of job stress. The subjects of this study are 267 Jeollanam-do public social worker. In particular, the structural equation model was used to analyze the mediating effects of job stress in the relationship between client violence and exhaustion. In addition, the significance of the mediation effect was utilized by the bootstrapping method. As a result, the significance of client violence → exhaustion, client violence → job stress, job stress → exhaustion path was confirmed. SMC value of exhaustion is .700, and client violence and job stress account for 70.0% of exhaustion. In the 95% confidence interval, the lower limit value and the upper limit value of the path coefficient were not included in 0, indicating that job stress was significant in estimating the significance of the job stress mediation effect through bootstrapping. In addition, the X2 difference value between the partial model (proposed model) and the fully mediated model (competitive model) was X2 = 5.047, df = 1. In other words, the hypothesis was rejected and the experimental hypothesis was adopted and the partial mediating model was selected. As a result, it was proved that there is a partial mediating effect of job stress on the relationship between client violence and burnout perceived by the public service Workers. Based on the results of this study, practical and policy suggestions to manage the exhaustion of public social worker 본 연구의 목적은 사회복지전담공무원이 인지한 클라이언트 폭력이 소진에 미치는 영향과 직무스트레스의 매개효과를 검증하는데 있다. 본 연구의 대상자는 267명의 전라남도 사회복지전담공무원이다. 특히 클라이언트 폭력과 소진 간 관계에서 직무스트레스의 매개효과를 분석하기 위해 구조방정식 모델을 이용하였다. 그리고 매개효과의 유의성은 Bootstrapping 방식을 활용하였다. 검증결과 클라이언트 폭력 → 소진, 클라이언트 폭력 → 직무스트레스, 직무스트레스 → 소진 경로의 유의성이 확인되었다. 그리고 소진의 SMC 값이 .700으로 나타나, 클라이언트 폭력과 직무스트레스가 소진을 70.0% 설명하는 것으로 보고되었다. 그리고 Bootstrapping을 통해 직무스트레스 매개효과의 유의성을 추정한 결과 95% 신뢰구간에서 경로계수의 하한 값과 상한 값이 0을 포함되지 않는 것으로 나타나, 직무스트레스의 유의성이 발견되었다. 아울러 부분매개모델(제안모델)과 완전매개모델(경쟁모델)의 X2 차이 값이 X2=5.047, df=1로 나타났다. 즉 영가설이 기각되고 실험가설이 채택되어 부분매개모델이 선택되었다. 결과적으로 사회복지전담공무원이 인지하는 클라이언트 폭력과 소진 간 관계에서 직무스트레스 부분매개효과가 존재하는 것으로 검증되었다. 본 연구의 결과를 기반으로 사회복지전담공무원의 소진을 관리할 수 있는 실천적, 정책적 제언을 제시하였다.
