To evaluate the sensitivity and specificity of Community Health Survey (CHS), we analyzed data from 11,217 participants aged ≥ 19 yr, in 13 cities and counties in 2008. Three healthcare utilization indices (admission, outpatient visits, dental visits) as comparative variables and the insurance benefit claim data of the Health Insurance Review & Assessment Service as the gold-standard were used. The sensitivities of admission, outpatient visits,and dental visits in CHS were 54.8%, 52.1%, and 61.0%, respectively. The specificities were 96.4%, 85.6%, and 82.7%, respectively. This is the first study to evaluate the validity of nationwide health statistics resulting from questionnaire surveys and shows that CHS needs a lot of efforts to reflect the true health status, health behavior, and healthcare utilization of the population.

This study collected 217 cases of court ruling statements for the cases over which administrative litigations were made regarding the acknowledgment of cerebral and cardiovascular diseases arising out of duty against Korea Labor Welfare Corporation and analyzed the factors of occurrence of cerebral hemorrhage and infarction and the Court cases of cancelation and dismissal of the litigation. As a result, due to seasonal factors, cerebral hemorrhage occurred more in the winter while cerebral infarction, in spring. The incidences for each age group were the higest in people in their 40s for cerebral hemorrhage while in those in their 50s for cerebral infarction, it turned that the incidence inside the places of business was the highest. The average days from application for care and family benefits until the confirmation of the case was 31 months on average for 34 canceled cases while 23 months for 183 dismissed ones, and the average number of months working until the occurrence of accident was 80.8 months for the 34 canceled cases while 77.6 for the 183 dismissed ones. This study has a significance in that it analyzed leading cases of confirmed administrative litigations in some cases applied for diseases due to occupational cases after the occurrence of cerebral and cardiovascular diseases but not approved, through which it is expected to be used as the basic data to reduce time and economic loss generated by the litigations to judge the acknowledgment of diseases due to occupational cases.

업무관련성 뇌ㆍ심혈관질환

임화영,최순영 대한안전경영과학회 2010 대한안전경영과학회 학술대회논문집 Vol.2010 No.04

Cerebrovascular and cardiovascular diseases (CVDs) are a major cause of deaths among workers as well as in general population in Korea. Occupational stress like long working hours or overwork can cause sudden unexpected death in a worker who had been suffering from an aggravated preexisting condition such as hypertensive or arteriosclerotic diseases, The Korean government has compensated the cases of cerebrovascular disease and cardiovascular disease due to overwork, but neither a resonable definition of overwork nor detailed evaluation guideline has been officially provided to verify overwork, so that the prevention of, as well as compensation for workers' occupational stress-related cardiovascular attacks, cannot be carried out efficiently. A thorough understanding of the etiopathology of WR-CVDs can be very helpful in developing a prevention strategy.

요양보호사의 전문성 인식에 관한 고찰

임화영 한국복지상담교육학회 2012 복지상담교육연구 Vol.1 No.1

2008년 7월 우리나라는 고령화 시대를 대비하고, 이로 인한 문제를 해결하기 위해 장기요양보험제도가 실시되었다. 또한, 이 제도를 위해서 이전의 요양서비스 인력을 국가자격증 체제로 통합한 요양보호사가 탄생되었다. 하지만 제도 시행 초 요양보호사들은 직업적인 안정성이나 업무영역에서 불완전한 상태에 있으며, 직업에 대한 사회적인 인식도 부족한 것이 현실이다. 그러나 요양보험의 운영형태나 추구하는 목표를 볼 때 요양보호사는 필연적으로 전문성을 갖추어야 한다는 당위성을 가지고 있다. 이러한 견지에서 본 연구는 요양보호사의 전문성 인식에 영향을 미치는 요인에 대해 알아보고자 하였다. 이를 위해 요양보호사의 인구사회학적 요인과 직무환경 요인과 전문성을 인식하는 척도에 대한 자료를 분석하였다. 이렇게 분석된 결과를 가지고 요양보호사의 전문직업성을 높일 수 있는 방안이 무엇인지를 모색해 보았고, 아울러 요양서비스 현장에서 요양대상자를 위해 힘겹게 근무하고 있는 요양보호사의 직무만족도를 향상시킬 수 있는 방법이 무엇인지 근거를 제시하고자 하는 목적을 가지고 연구를 진행하였다. 연구 결과를 토대로 본 연구에서는 요양보호사의 전문직업성을 향상시키고, 직업만족도를 높이기 위해 정책 및 요양보호사 스스로 개선할 부분이 무엇인지를 밝히고, 앞으로 나아가야할 방향을 언급하였다. In Republic of Korea, Long-term care insurance system has carried into effect since 7, 2008 for Aged period and solving the problem about it. For the case of this system caregivers, integrating the former nursing service staffs into public qualification, was born. But in this system caregivers' vocational stability or business management remains unstable. In addition, social recognition of the vocation is not yet satisfied in reality. However, from the point of view of management systems of care insurance or pursuing object, caregivers must necessarily have a professionalism. In this respect my research shows that what factors have an effect on recognition of professionalism of caregivers. This research conducted that both Personal characteristics factors and Work environment factors are independent variable and the indexes of recognition of professionalism are dependent variableit, analyzing two correlation mentioned above. Within analyzed results I found a way to improve professionalism and proceeded research about improving Job satisfaction of caregivers According to survey, work environment factors have an less influence on workload or compensation than expectation, while relationship of business nature -such as skill- and recipients of caregivers have an more influence on recognition of professionalism. Based on these results main research reveal that to improve professionalism and job satisfaction what policy is needed and caregivers themselves must try to improve ways.

多重接地된 사다리꼴 回路網의 零相電流 分布 解析

任化永 光云大學校 1983 論文集 Vol.12 No.-

In three-phase, four=wire, multi-grounded distribution systems, distribution of the fault current along the common neutral lines of two-port ladder network which incorporate muturally-coupled elements is subject to change in accordance with the degree of the irregularity of the footing resistance and the presence of branched neutral wires. This paper describes the developed algorithm and program for computing zero-sequence current and voltage distribution of the systems, which are applicable to any grounded network constructions and fault conditions. In the case of uniformly distributed footing resistance from neutral wires, the current and voltage distribution can be determined on the various fault condition by using basic formulas developed in this paper. These formulas can be extend, in any fault condition, to compute the accurate zero-sequence impedance of the over-head lines with grounded wires.

As the society becomes more industrialized, utilities increased and load concentrated, the conventional analog reclosers often meet difficulties when they are applied to long distance distribution lines, heavily loaded system, complex structure, and so on. This paper proposes digital recloser improved protection capabilities by utilizing micro-processor. Further the newly suggested protection policy shows the effectiveness for the inrush current at loading and unloading operations.
