Purpose: The purpose of this cross-sectional study was to examine the relationship between characteristics of severe ALS patient-caregiver couples and health related quality of life (HRQoL) in family caregivers. Methods: The participants in this study were 89 pairs of ALS patients using ventilators and a family caregiver. The characteristics of the ALS patients and caregivers, Korean-Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised, Zarit Burden Interview and SF-36 were measured in

Two novel quinacridone (QNC) dyes with thiophene or benzene-conjugated bridge and cyanoacrylic acid acceptor were first designed and synthesized for use in dye-sensitized solar cells (DSSCs). The absorption spectra, electrochemical and photovoltaic properties of these dyes were investigated. Under simulated AM 1.5G irradiation conditions, the solar cell based on the quinacridone dye containing thiophene as a bridge unit had a short-circuit photocurrent density of 8.51 mA·cm^−2, an open-circuit v

이 내러티브 탐구의 목적은 거듭되는 국가교육과정 개정 담론 속에서 초등학교 통합교과 교육과정이 실행되는 과정에서 변화하는 교사 행위 주체(teacher agency)1)의역할은 무엇인지를 탐색하고자 한다. Homi Bhabha의 제3의 공간(the third space) 이론에 비추어 교사 행위 주체의 역할은 어떠한 의미를 지니는지 국가교육과정 맥락과교사의 교육과정 실천을 살펴봄으로써 ‘틈새(in-between space)’에 위치해 있는 교사행위 주체의 역할을 이해하고자 한다. 이 연구는 질적 연구로서 서울과 경기도의 공립 초등학교의 연구 참여자 교사들의 내러티브를 중심으로 진행되었다. 이 연구는 교사들이 국가교육과정에 의한 통합교과를 실행하는 과정에서 교사 행위 주체로서 국가교육과정 맥락과 학교 문화, 교사 문화 맥락 사이에서 어떠한 역할을 하게 되는지그들의 내러티브를 통해 탐색함으로써 변화하는 국가교육과정의 맥락에서 교사들의위치를 이해하는데 그 목적이 있다.

Objective: To investigate the current status of respiratory care in community-dwelling amyotrophic lateral sclerosis (ALS) patients using non-invasive ventilatory support. Method: Trained investigators visited patients’ homes in order to conduct the survey. Questions regarding the time since diagnosis and ventilatory support, department and type of ventilator were asked. The parameters of mechanical ventilation were noted. The presence of respiratory symptoms, frequency of oxygen saturation moni

Secondhand smoke (SHS) is one of major public health threats. Since secondhand smoke is complex mixture of toxic chemicals, there has been no standardized method to measure SHS quantitatively. The purpose of this manuscript was to review various quantitative methods to measure SHS. There are two different methods: air monitoring and biological monitoring. Air monitoring methods include exhaled carbon monoxide level, ambient fine particulates, nicotine and 3- ethenylpyridine. Measurement of fine

Objective: To find out the actual state of smoking, which is one of major risk factors of cardiovascular diseases after spinal cord injury (SCI), of community-dwelling persons with SCI, and the differences of smoking behaviors from general populations. Method: The persons with SCI living in community drew up a self-report paper-based questionnaires which were made up based on The third Korea National Health and Nutrition Examination Survey questionnaires for data comparisons. Demographic data, s

최근 학교 맥락에서 대두되는 통합에 대한 관심은 통합교과 교육과정의 개정과 교과서 개편에 대한 기류로 작용하고 있다. 학교 현장에서는 이러한 통합에 대한 관심만큼 통합교과 실천에 대한 여러 가지 시도들이 이루어지고 있고, 다양한 상황적 맥락이 작용하고 있다. 본 연구는 초등학교 교사들이 통합교과를 실천하는 장면에서 ‘통합’을 어떻게 전개하고 있는지 그 특징을 살펴보고, 이러한 실천을 둘러싸고 있는 다양한 상황적 맥락을 통하여 통합교과 실천의 다각적인 측면을 탐색하고자 한다. 이를 위하여 연구자는 질적 연구 방법을 활용하였으며, 초등학교 1학년 교사 5명의 수업을 관찰하고 이들과의 심층면담을 통하여 자료를 수집하였다. 자료의 분석과 해석을 통하여 통합교과의 실천은 교사들이 국가교육과정, 통합교과서를 구현하는 상황에서 가시적, 비가시적으로 드러나는 여러 측면이 있음을 발견하고 이를 전경과 배경의 틀로 살펴보았다. 즉, 통합교과 실천의 양상에서 전경으로 부각되는 것과 배경으로 파악될 수

Exposure analysis is a critical component of determining the health impact of pollutants. Global positioning systems (GPS) could be useful in developing time-location information for use in exposure analysis. This study compares four low cost GPS receivers with data logging capability (Garmin 60, Garmin Forerunner 201, GeoStats GeoLogger and Skytrx minitracker MT4100) in terms of accuracy, precision, and ease of use. The accuracy of the devices was determined at two known National Geodetic Surve

Secondhand smoke (SHS) is one of major public health threats in morbidity and mortality. Several national and regional comprehensive smoke-free regulations have been implemented to prevent public health exposure, but not in Korea. The purpose of this manuscript was to review impacts of the national or regional smoke-free legislations on indoor air quality, health effects and smoking behaviors. Indoor air quality has been improved significantly after smoke free policy. Such improvement was measur

Purpose: Pressure sore wound develops inevitably in long-term, immobilized and hospitalized patients. Sore wound infection is common problem and makes healing process difficult. We aimed to identify the pathogens of the purulent discharge in sore wound and to obtain information for appropriate antibiotics through a sensitivity testMethods: The bacteriologic study was made on 120 cases of patients who admitted or visited our hospital from 2004 January to 2005 December for sore wound treatment. Cu

Objectives: To investigate the relationship between the findings of the electrodiagnostic study (EDX) and clinical evaluation in patients with classical thoracic outlet syndrome (TOS). Methods: Retrospective medical record review was done in 49 patients (age 46.7±15.1 years, 19 men) with clinically suspected TOS, referred for EDX from October 2003 to March 2010. EDXs were performed at 24.1±33.7 months from symptom onset. Ulnar and median, sensory and motor nerve conduction studies (NCS) were don

Objective: To describe the quality of life (QOL) and care burden of caregivers of ventilator-dependent amyotrophic lateral sclerosis (ALS) patients and to compare the QOL of ALS caregivers with that of dementia caregivers. Method: Ninety-one pairs of ALS patients and their caregivers were interviewed. Patients were asked to provide their age, sex, time since diagnosis, and length of ventilator use, as well as complete the ALS functional rating scale- revised (ALSFRS-R). Caregivers were asked to

Objective To develop a simplified functional scale and classification system to evaluate the functional abilities of patients with Duchenne muscular dystrophy (DMD). Methods A Comprehensive Functional Scale for DMD (CFSD) was developed using the modified Delphi method. The accompanying Ambulatory Functional Classification System for DMD (AFCSD) was developed based on previously published classification systems. Results The CFSD consists of 21 items and 78 sub-items, assessing body structure and

Objective To compare the motor recovery following transverse myelitis in pediatric patients with and without spinal cord atrophy. Method From January 1995 through December 2009, twenty children (8 boys and 12 girls with an onset at 5.7±3.8years) that were diagnosed with transverse myelitis at a Children’s Hospital in Korea, and undertaken an initial and follow-up spine magnetic resonance image (MRI) were included. Medical records and spine MRI scans were reviewed retrospectively. An initial MRI

This article describes the design of a hydraulic system for a power split type continuously variable transmission (CVT). The CVT considered here, is composed of planetary gears, clutches, and a torque converter which is mainly used for the realization of CVT function. Similar to automatic transmissions, the hydraulic system of CVT is designed for supplying hydraulic flows and pressures to each component of CVT, in order to activate the clutch engagements and torque converter operation, and to co
