Background : Vasovagal syncope has been believed to account for the majority of syncope of unknown origin (SUO). Head-up tilt test (HUT) has been well recognized as a useful test in the evaluation of SUO. The purpose of this study was to determine the predictors of HUT to develop a less time-consuming test protocol and get an information on the pathophysiology of vasovagal syncope. Methods : Eighty five patients (mean age, 43±18 years: 47 men, 38 women) underwent a 80 degree HUT without or with isoproterenol infusion (2 μg/min and 5 μg/min, each for 6 minutes) for unexplained syncope or pre-syncope. Positive HUT was defined as symptomatic hypotension (systolic blood pressure ≤80 mm Hg) and/or symptomatic bradycardia (≤45/min for ≥10 seconds) or asystole ≥3 seconds. The patients were divided into two groups according to the result of the HUT: Group I included 47 patients (M:F=25:22) with positive result, Group II, 38 patients (M:F=22:16) with negative result. Results : Group I patients had more episodes of syncope than Group II (3.1±2.5/year vs. 2.0±2.1/year, p<0.05). There were no significant differences between the 2 groups in the heart rate (HR), systolic and diastolic blood pressure (BP) at the baseline supine position. BP after tilt was not significantly different between 2 groups except for systolic BP at 6 minutes after tilt, which was significantly lower in Group I than Group II (109.5±17.5 mm Hg vs. 118.1±18.2 mm Hg, p<0.05). However, HR after tilt was significantly faster in Group I than Group II (81.1±15.1/min vs. 74.2±14.9/min, p<0.05 at 2 minutes after tilt; 83.7±14.4/min vs. 74.6±14.7/min, p<0.01 at 4 minutes after tilt). The increase in HR was greater in Group I than Group II (19.9±12.6/min vs. 12.8±10.6/min, p<0.001). In the prediction of positive HUT with HR rise above 14/min during the early 6 minutes of baseline head-up tilting, the specificity, sensitivity, and positive predictive value were 63.2%, 70.2%, and 70.2%, respectively. Conclusion : In patients with SUO, positive HUT can be predicted with the early HR response during head-up tilt. This result shows that vasovagal syncope is triggered by exaggerated HR response to the decreased venous return and allow us to develop a less time-consuming HUT protocol.(Korean J Med 61:133-140, 2001)

희망스타트 사업에 대한 복지정책적 분석

정은아 ( Eun A Jeong ) 서울여자대학교 사회복지연구센터 2010 사회복지실천 Vol.9 No.-

본 연구는 사회투자정책으로 시작된 희망스타트 사업을 Gilbert & Terrell의 분석틀에 기반하여 분석하여, 주요 문제점들과 적절한 해결방안을 모색하는 것이 목적이다 분석 결과 첫째, 사회적 할당에서는 기초생활수급자가정과 차상위계층의 0∼12세 아동과 가정을 목표로 하고 있지만, 프로그램 지원대상 비율은 1.13%에 불과하여 외국의 경우와 비교할 때 턱없이 부족한 상황이었다. 둘째, 사회적 급여의 내용에서 아동에 대한 통합서비스는 직접적인 현금급여 없이 현재와 같이 현물급여만으로는 그 효과를 모두 기대하기는 힘들 것으로 판단된다. 셋째, 전달체계에서는 대부분 지역이 민간위탁방식으로 조직되어 있어 보편적 서비스의 확대를 위해서는 전담공무원 배치와 사업에 대한 효과평가 시스템이 갖추어져야 할 것이다. 넷째, 재원에서는 노인이나 장애인에 비해 아동청소년 예산 자체가 매우 미흡한 상태이며, 희망스타트 사업 또한 5,050백만원으로 그 예산비중이 매우 작은 상태이다. 이상과 같은 분석 결과를 볼 때 희망스타트 사업의 급선무는 우선 지속적으로 추진되도록 사회적 공감대를 확대하는 일이며, 빈곤의 세습화를 막기 위해 아동을 대상으로 시행하는 사회투자정책은 장기적으로 계획되어야 하며, 지속적인 관심과 시간, 재정지원이 충분히 뒷받침된 후에 그 성공여부를 평가하는 일이 바람직 할 것으로 판단이다. 또한 탈아동빈곤정책은 소득지원, 소득보전과 더불어 아동의 건강, 영양, 정서, 인지 등의 총체적인 발달을 도모할 수 있는 통합적이고 강화된 사회복지서비스가 필요하며, 이를 위해 정부의 좀 더 적극적 재정지원에 기반 한 공공성을 강화하기를 기대한다. This study tries to find the major prblems and proper solutions of the HEEMANG START program by analysing the program based on the Gilbert & Terrell`s policy analysis framework. Findings show that only 1.13% of welfare recipients who have 0-12 year-old children can access this program. Therefore in terms of social allocation, this situation is far from enough. This study also finds that direct cash benefits should be more provided for those families with children, in terms of social provisions. In addition, it is needed to increase the number of public agents to expand the range of recipients, and also the performance rating system for the program should be established. In terms of finances, the public budget for the youth is relatively small compared with those for the aged or the disabled.

사회서비스 제공에서 비영리 교육기관의 역할과 정책과제

정은아(Jung Eun A),김은정(Kim Eun jeong) 경성대학교 사회과학연구소 2010 社會科學硏究 Vol.26 No.2

본 연구는 최근 사회서비스 전달주체가 다원화되면서 사회서비스 제공에서 중요한 역할을 담당하고 있는 비영리 고등교육기관에 대한 정책적 분석을 시도하였다. 이를 위해 사회서비스 전달주체의 현황과 특성을 민간비영리기관과 교육기관을 중심으로 검토하고, 대부분 비영리 고등교육기관으로 구성된 ‘지역사회서비스 청년사업단을 중심으로 이들이 제공하는 사회서비스의 급여대상, 전달주체, 급여의 형태, 재원 등을 분석하였다. 이를 바탕으로 사회서비스 제공영역에서 비영리교육기관의 역할과 정책과제를 제시하면 다음과 같다. 첫째, 급여대상자 확대를 통해 보편적 사회서비스 제공 기반을 확보함에 있어서 비영리교육기관이 역할을 담당할 필요가 있다. 둘째, 사회적 연대를 강화하고 공공성을 확대시킬 수 있는 바람직한 사회서비스를 발굴하고 이를 확대시키는데 있어서 비영리 고등교육기관이 역할을 담당해야만 한다. 또한 이러한 서비스가 이용자 선별이나 비용부담의 역진성 문제없이 제공될 수 있도록 전달방식을 개선함에 있어서도 비영리 고등교육기관의 역할이 기대된다. 셋째, 사회적 기업과 같은 바람직한 사회서비스 산업을 육성함에 있어서도 비영리 고등교육기관이 중요한 역할을 해야 한다. 본고에서의 분석이 사회서비스 영역에서 비영리 고등교육기관의 바람직한 역할정립을 위한 정책논의의 기초자료가 될 수 있기를 기대한다. This study tries to analyze the roles and tasks of educational organizations in providing social services. Educational organizations are currently noted in terms of their roles in providing social services and training diverse professions in social service domains. First of all, this study reviews the notions and major characteristics of social services and the current features of non-profit organizations and educational organizations as their major roles in social service delivery. Then, this study introduces the "Youth-Groups for Social Services" which have started service delivery since 2009. Based on Gilbert & Terrell's policy analysis framework, this study investigates the entitlements, the ways of delivery, service contents, and finances of "Youth-Groups for Social Services." The proper roles of educational organizations which this study proposes are as follows. First, educational organizations should contribute to widen the range of social service beneficiaries by establishing the policy framework of social service. With the aim of directing to universalism (not to selectionism) in terms of social service entitlement, educational organizations should actively find out the ways to increase the numbers of social service beneficiaries and enhance the quality of social services. Second, educational organizations also tries to discover the proper contents of social services increasing cohesions of social groups and social justice. In addition, educational organizations should endeavor to find out the ways to deliver social services effectively and efficiently. Third, educational organizations also can carry off bringing up social enterprises delivering social services.

취약가정 아동청소년 멘토링 서비스의 품질과 지속적 이용의사

정은아(Eun-A Jeong),김은정(Eun-Jeong Kim) 계명대학교 사회과학연구소 2009 한국사회과학연구 Vol.28 No.2

This study investigates the quality of mentoring services for disadvantaged children focusing on the five components of services quality, and analyzes the level of quality assessed by parents of service users and their service loyalty. Data were collected by "Keimyung Love Sharing Young Mentoring Group" delivering mentoring services for disadvantaged children living in Dalsung-Gun, Daegu, Korea. Study findings show that most parents of children receiving mentoring services satisfy the quality of those services. The average score is over 4.5(full score-5). In addition, the quality dimensions of sociality, assurance, and empathy get higher scores than those of reliability and responsibility, though the score differences are small. Hierarchical multiple regression reveals that the quality dimensions of reliability and assurance significantly influence the level of service loyality among childrens' parents using mentoring services. Especially the quality dimension of reliability have the strongest impact on the level of service loyality. Reliablity relates to whether service providers keep their promise and make a record on what they did.

정은아(Eun A Jeong),김지우(Ji U Kim),염한길(Han Kil Yeom),윤소남(So Nam Yun) 유공압건설기계학회 2015 드라이브·컨트롤 Vol.12 No.4

This paper deals with the flow characteristics of a reed valve analyzed using computational dynamics(CFD) for optimal design. The seat sizes of the valve are modeled as Ø6[mm] and Ø8[mm] to compare the flow characteristics. The inlet boundary condition is entered at 10[kPa], 15[kPa], 20[kPa], and 30[kPa] and the outlet boundary condition is set to the atmospheric pressure. The flow coefficient(C) and pressure loss coefficient(K) are calculated from the results of flow analysis. From the analysis results, it was confirmed that the flow coefficient of a reed valve having a seat size of Ø6[mm] is greater than that having a seat size of Ø8[mm], and the coefficient of pressure loss of a valve with a seat size of Ø6[mm] is lower than the Ø8[mm] size valve.

This paper deals with a Poly(arylene ether sulfone)copolymer which is a kind of component of the Fuel Cell and is a key element of the PEMFC. 3,3′-Sulfonated-4,4′dichlorodiphenyl sulfone (SDCDPS) is composited by 4, 4′-Dichlorodiphenyl sulfone (DCDPS) and Fuming sulfuric acid whose ratio is 1 : 3.3 and is derived from Elec trophilic Sulfonation. Also, purified 3,3′-Sulfonated-4,4′-dichlorodiphenyl sulfone (SDCDPS) is gotten by recrystallization procedure of Isopropanol-H2O. Sulfonated Poly(arylene ether sulfone) (SPAES) is synthesiszed from 3,3′-Sulfonated-4,4′-dichlorodiphenyl sulfone (SDCDPS), 4,4′-Dichlorodiphenyl sulfone (DCDPS) and 4,4′ -Biphenol, and is called Aromatic Substituton and Condensation Polymerization. Poly(arylene ether sulfone) copolymer which has a very high viscosity is synthesised through direct polymerization using Potassium carbonate to catalyst. The result of synthesis are confirmed by methods such as FT-IR Spectrum and 1H-NMR Spectrum.
