본 연구는 자활사업에서 효과적이고 효율적인 성과관리 체계 구축을 위한 성과관리 의 규범적 전제에 대해 논의하고 자활지원센터에 대한 성과평가와 규모별 보조금 지원 체계를 둘러싼 논쟁을 성과관리 측면에서 평가하였다. 이와 더불어 최근 한국 사회서비스 영역에서 성과평가의 논리적 구조로 활용되는 논리모델을 적용하여 현재 논의의 중 심이 되고 있는 성과평가 지표를 재구성하였다. 이를 통해 본 연구는 자활사업 성과관리 체계 및 성과평가 체계 개선을 통해 자활사업 전반의 합리화를 추구하고, 탈빈곤 - 탈수급 목표에 집중할 수 있는 지원체계 구축에 궁극적으로 기여하고자 하였다. 자활사업 성과관리 체계는 자활사업 목적과 일치하면서 자활사업의 효과 증진을 목적으로 구축되어야 하는 것이 기본적인 전제이다. 그리고 효과적이고 효율적인 성과평가 체계 구 축을 위해서는 규모별 지원과 성과평가에 근거한 인센티브의 혼재를 극복하고, 지역자 활센터의 실제를 반영한 과정지표들이 적극적으로 반영되어야 하며, 지역적 특성이 고려되어야 한다. 또한 자활사업 성과평가 지표는 투입-활동-산출-결과 측면에서 균형적으로 구성될 필요가 있다. This study discussed the basic premise related to the establishment of performance management system in self-sufficiency program in Korea, and evaluated the performance evaluation system and the budget support principles to self-sufficiency agency with the notions of performance management. Then, this study suggested the indicators of performance evaluation of the agency with logic model which used for social service evaluation. This study aimed to rationalize the management of self-sufficiency program, contribute to achievement of the goal of the program. Firstly, to establish the effective performance management system, we should consider the basic premise of performance management that matches the goal of the program and the role of the agency. Secondly, we should resolve the confusion between the budget support system depending on the number of participants and incentive to the performance, and process indicators and outcome indicators should be included in the performance evaluation in equilibrium, and we should consider the regional difference surrounding the performance. Lastly, we should develop the performance evaluation system including the performance indicators to measure input, activity, output, and outcome.

본 연구는 최근 주요한 사회 문제로 등장한 비정규 노동과 근로빈곤의 관계를 분석하였다. 비정규직의 빈곤위험은 정규직에 비해 4배 높았으며, 근로빈곤층의 1/3을 비정규직이 구성하였다. 비정규직의 월 임금은 정규직의 54.6%로 큰 격차를 보였으며, 근로시간을 통제했을 때 비정규직의 상대임금은 정규직의 73.0%로 임금격차가 감소한다. 비정규직과 정규직의 빈곤율 차이를 특성 차이로 인한 부분과 차별로 인한 부분으로 분해한 결과, 비정규직의 임금격차는 주요하게 생산성 차이에 기인한 것으로 나타나, 임금차별로 설명되는 임금격차, 빈곤율 차이는 거의 없었다. 그렇지만 비정규직의 근로시간이 정규직과 같은 수준으로 증가할 때 비정규직의 빈곤율은 26~37%정도 감소하는 것으로 나타났다. 이러한 결과는 비정규직의 빈곤 문제 해결을 위해서는 이들의 생산성 확대를 위한 인적자본에 대한 투자와 근로시간증대를 위한 노력이 중요함을 보여준다. This study assesses the relationship between non-regular employment and working poor in Korea. The poverty rate of non-regular workers is four times higher than that of regular workers. One third of all the working poor are non-regular workers. The poverty rate of disadvantaged workers in regular employment is also striking. The monthly relative wage and hourly relative wage of non-regular workers is 54.6 percent and 73.0 percent respectively. The level of household income among non-regular workers is still lower than that among regular workers even after tax and social security benefits are accounted for. As a result, non-regular workers and their family are more likely to be poor. Results from the simulation analyses which remove wage differential between regular workers and non-regular workers show that wage differential among workers is not due to wage discrimination but due to differential of productivity. The expending of employment stability, however, has reducing effect on poverty rate of non-regular workers. The poverty rate of them is reduced about 26~37% percent when their working time is increased as much as regular workers'. The findings suggest that the increasing non-regular employment should be addressed to lessen the poverty of working families. The development of human capital and improved employment security for non-regular workers would effectively improve their economic well-being.

Background/Aims: We performed a prospective study to determine the efficacy and safety of rituximab including chemotherapy in CD20-positive acute lymphoblastic leukemia (ALL). Methods: Patients with newly diagnosed ALL, aged ≥ 15 years, were eligible for the study if their leukemic blast cells in bone marrow expressed CD20 ≥ 20% at the time of diagnosis. Patients received multiagent chemotherapy with rituximab. After achieving complete remission (CR), patients received five cycles of consolidation with concomitant rituximab. Rituximab was administered monthly from day 90 of transplantation for patients who received allogeneic hematopoietic cell transplantation. Results: In patients with Philadelphia (Ph)-negative ALL, 39 of 41 achieved CR (95.1%), the 2- and 4-year relapse-free survival (RFS) rates were 50.4% and 35.7%, and the 2- and 4-year overall survival (OS) rates were 51.5% and 43.2%, respectively. In the group with Ph-positive ALL, all 32 patients achieved CR, the 2- and 4-year RFS rates were 60.7% and 52.1%, and the 2- and 4-year OS rates were 73.3% and 52.3%, respectively. In the Ph-negative ALL group, patients with higher CD20 positivity experienced more favorable RFS (p < 0.001) and OS (p = 0.06) than those with lower CD20 positivity. Patients who received ≥ 2 cycles of rituximab after transplantation had significantly improved RFS (hazard ratio [HR], 0.31; p = 0.049) and OS (HR, 0.29; p = 0.021) compared with those who received < 2 cycles. Conclusions: The addition of rituximab to conventional chemotherapy for CD20-positive ALL is effective and tolerable (Clinicaltrials.gov NCT01429610).
Pneumoconiosis in a polytetrafluoroethylene (PTFE) spray worker

Background: Using analysis of air samples from the workplace, we report on one case of pneumoconiosis in an individual who has been working in a polytetrafluoroethylene (PTFE) spraying process for 28 years. Case presentation: The patient was diagnosed with granulomatous lung disease caused by PTFE using computed tomography (CT), lung biopsy and electron microscopy. To assess the qualitative and quantitative exposure to PTFE in workplace, Fourier transform infrared spectroscopy (FT-IR), energy-dispersive X-ray spectroscopy (EDX) and thermogravimetric analysis (TGA) were performed on air samples from the workplace. The presence of PTFE particles was confirmed, and the airborne concentration of PTFE was estimated to be 0.75 mg/㎥. Conclusions: This case demonstrates that long-term exposure to PTFE spraying can cause granulomatous lung lesions such as pneumoconiosis; such lesions appear to be caused not by the degradation products of PTFE from high temperatures but by spraying the particles of PTFE. Along with air-sampling analysis, we suggest monitoring the concentration of airborne PTFE particles related to chronic lung disease.
