The periodic sharp wave complexes are the most characteristic EEG abnormalities in sCJD. We report the serial EEG findings in a patient with probable sCJD. The initial EEG showed diffuse theta and delta slowings only. However, it changed to the typical periodic sharp wave complexes according to the worsening clinical state. These changes occurred during a short-term interval. The serial EEGs within the short-term interval will be helpful for the earlier diagnosis of sCJD.

The purpose of this study was to develop and validate a scale that can measure the play support efficacy of early childhood teachers. To this end, first, literature analysis, open-ended questionnaires and in-depth interviews were conducted for early childhood teachers in the field to extract constituent factors and items, and through three Delphi surveys, preliminary items were selected for the play support efficacy scale for early childhood teachers. Second, through a preliminary survey conducted on 103 early childhood teachers, a proposal was made for the construct validity of preliminary questions and a draft of the play support efficacy scale for early childhood teachers. Third, the suitability and reliability of the factor structure of the development scale were verified through exploratory factor analysis, confirmatory factor analysis, and reliability analysis as a result of the main survey of 408 early childhood teachers. Fourth, in order to validate the scale developed in this study, the criterion-related validity was confirmed through correlation analysis between the existing teacher efficacy scale and the teacher effectiveness scale for teacher's play. The early childhood teacher's play support efficacy scale developed through these steps consisted of 4 components, 10 factors, and 51 items, and was confirmed to be a valid and reliable measure for measuring the play support efficacy of early childhood teachers. 본 연구의 목적은 유아교사의 놀이지원효능감을 측정할 수 있는 척도를 개발하고 타당화 하는 것이다. 이를 위해 첫째, 문헌분석과 현장의 유아교사를 대상으로 개방형 설문, 심층면담을 진행하여 구성요인과 문항을 추출하고, 3회에 걸친 델파이조사를 거쳐 유아교사 놀이지원효능감 척도의 예비문항을 선정하였다. 둘째, 3~5세 유아반 담임교사 103명을 대상으로 예비조사를 실시하여 예비문항의 구성타당도를 확인하고 유아교사 놀이지원효능감 척도의 시안을 구성하였다. 셋째, 유아교사 408명을 대상으로 이루어진 본조사 결과로 탐색적 요인분석과 확인적 요인분석, 신뢰도 분석을 통해 개발척도의 요인구조의 적합성과 신뢰도를 검증하였다. 넷째, 본 연구에서 개발한 척도의 타당화를 위해 기존의 교사효능감 척도와 교사의 놀이에 대한 교수효능감 척도와의 상관관계 분석을 통해 준거관련타당도를 확인하였다. 이러한 단계를 통해 개발된 유아교사 놀이지원효능감 척도는 4개 구성요인, 10개 요인, 51문항으로 구성되어 유아교사의 놀이지원효능감을 측정하는데 타당하고 신뢰로운 척도임이 확인되었다.

In this study, the floor impact sound insulation performance of Korean domestic Cross-Laminated Timber (CLT) slabs was evaluated according to their joint types, species and thicknesses in laboratory experiments. The sound insulation performance of the CLT has not been investigated before, thus, this study was conducted to quantify basic data on floor impact sound insulation performance of CLT slabs. 5-ply and 150 mm thick CLT panels made of 2 species, Larix kaempferi and Pinus densiflora, were used for the study. The CLT panels were assembled by 3 types of inter-panel joints to form floor slabs: spline, butt and half-lap. And the 150 mm thick Larix CLT slabs were stacked to the thicknesses of 300 mm and 450 mm. The heavy-weight floor impact sound insulation performance of the 150 mm CLT slabs were evaluated to be 70 dB for the Larix slabs and 71.6 dB for the Pinus slabs, and the light-weight floor impact sound insulation performance, 78.3 dB and 79.6 dB, respectively. No significant difference in the sound insulation performance was found between the slabs of the 2 species or among the 3 types of joints. The reduction of 1 dB in the heavy-weight floor impact sound and 1.6 dB in the light-weight floor impact sound per 30 mm increase in thickness were confirmed through the experiments. This study can be viewed as the basic research for the evaluation of floor impact sound insulation performance of CLT.

경동맥스텐트삽입술 시술 전 평가와 시술 전후 관리

Carotid-artery stenting (CAS) is as an alternative to surgical endarterectomy for severe carotid-artery stenosis. CAS isadvantageous over carotid endarterectomy in that it is less invasive and could shorten the hospital stay. A preproceduralevaluation is necessary to assess the patient’s anatomic status or clinical risk factors to determine whether they are a goodcandidate for CAS. Proper evaluation and management can reduce CAS-associated complications such as embolism andcerebral hyperperfusion syndrome. The frequent use of statins appears to improve the outcome of CAS. Using theappropriate stent type and a protection device could also reduce the complication rate. Given the changes in cerebralhemodynamics following CAS, adequately controlling the blood pressure in individual patients can enhance the efficacyof this treatment. However, there is currently limited data regarding the preprocedural evaluation and periproceduralmanagement for CAS. The evidence and the clinical status related to the preprocedural evaluation and periproceduralmanagement of CAS are presented herein.

하연수 한국문화융합학회 2023 문화와 융합 Vol.45 No.9

The purpose of this study was to analyze the priorities of early childhood teachers' demands for improvement in play support, identify factors that should be prioritized to improve early childhood teachers' play support, and provide basic data for related program development and educational materials. For this purpose, a survey was conducted on 234 kindergarten teachers. To analyze needs priorities, t-test, Borich needs analysis, and The locus for focus model type analysis were used. As a result of the study, the factors that should be considered as top priorities for improving play support for early childhood teachers were analyzed as 3 factors of play observation and understanding, 1 factor of play environment support, and 1 factor of play support reflection. Play interaction factors were not included in the needs or priorities. As a result of analyzing the priorities for improvement in each field of early childhood teacher play support, it was found that early childhood teacher play support requires efforts to improve circular practice of supporting, interacting with and reflecting on the play environment based on play observation. Based on these research results, implications for improving play support for early childhood teachers were presented.

Various Complications after a Vascular Procedure in Patients with Hemophilia

하연수,박영실 대한소아혈액종양학회 2019 Clinical Pediatric Hematology-Oncology Vol.26 No.1

Hemophilia, an inherited bleeding disorder, is caused by a deficiency of coagulation factor VIII or IX. Most of patients with hemophilia need vascular procedure, which can lead to complications. Even though these complications can also occur in normal people, hemophilia and coagulopathy are particular risk factors. We reviewed medical records of patients with hemophilia who underwent vascular procedures and investigated its complications. Vessel-related complications occurred in five patients. Three patients had pseudoaneurysms after radial arterial puncture. All patients underwent coagulation factor replacement or ultrasound-guided compression and showed improvement. Neuropathy developed in one patient due to a hematoma that occurred after blood sampling. The hematoma improved, but motor and sensory deficits remained and neuropathy was confirmed. One patient died of uncontrolled bleeding after angiography. Vascular procedures require more attention in patients with hemophilia. Caution and prevention of complications is essential, even before the patient is diagnosed with hemophilia.

하연수,한상원,조광철,남효석,김정연,백종삼,박재현 대한신경과학회 2006 대한신경과학회지 Vol.24 No.2

Background: This study aimed at characterizing the lesion patterns in patients with acute ischemic stroke and complicated aortic plaques using the diffusion-weighted magnetic resonance imaging (DWI). Methods: We retrospectively reviewed 403 consecutive patients with acute ischemic stroke between January 2002 and December 2004, and enrolled patients who had received a trans-esophageal echocardiography (TEE). All the patients should have an acute cerebral infarction within 7 days of the onset of symptoms. We analyzed the ischemic lesion patterns on DWI in the patients who had aortic atheroma protruded into the lumen greater than 4 mm in the aortic arch or ascending aorta (complicated aortic plaques; CAP). Ischemic lesions were classified into subcortical, cortical and multiple infarctions. We investigated the accompanying risk factors for atherosclerosis and stenosis of the relevant major brain artery as well. Results: Of the 403 patients, TEE was performed in 210 (52%) and CAP was found in 25 (12%). Among 25 patients, subcortical infarction was observed in 15 (60%), followed by cortical infarction in 7 (28%), and multiple ischemic lesions in 3 (12%). CAP was frequently associated with hypertension and current smoking, and accompanied with stenosis of the relevant major brain artery as well (68%). Conclusions: CAP may be a potential source of embolism. However, the high prevalence of the small subcortical lesion in this study questions the mechanisms of ischemic stroke in patients with aortic atheroma. CAP may be an uncomplicated marker of advanced systemic atherosclerosis including the cerebral arteries.
