This paper intended to compare national involvement, administrative system, delivery and financing system, and public-private provision mix of U.K., U.S. and Germany in child care policies. This paper focused on the similarities and differences of three countries of three countries. The similarity of three countries is reluctant and implicit child care policy direction emphasizing family responsibility. They have developed child care services which combined motherhood ideology of division of gender and individualism. Child care policies in three countries are divided into two regimes. One is U.K. and U.S. with liberal regime, the other is Germany with conservative regime. U.K. and U.S. have withdrawn the public sector child care institutions which had been provided in war time to use women labor force, and formed residual and selective child care polices up to the present. Germany have gradually developed child care polices within the limited level representing a partnership among central, local government and private voluntary welfare association.

The stress singularity of a sharp wedge contacting a half plane can be avoided by changing the wedge shape. Shape optimization is accomplished with the geometric strain method (GSM), an optimality criterion method. Several numerical examples are provided for different materials in the wedge and half plane to avoid stress singularity neal the sharp corner of the wedge. Optimum wedge shapes are obtained and critical corner angles are compared with the angles from analytical contact mechanics. Numerical results are well matched to analytical and experimental results. It is shown that shape optimization by the geometric strain method is a useful tool to reshape the wedge and to avoid a stress singulatiry. The method applies to more general geometries where the singular behavior would be difficult to avoid by classical means.

사회복지 생활시설 종사자의재해·안전실태와 법적 고찰

박정선,박찬임 사회복지법제학회 2017 사회복지법제연구 Vol.8 No.1

본 연구는 사회복지 생활시설 종사자에 관한 연구에서 그간 소홀히 다루어졌던 재해와 안전에 초점을 두고, 사회복지 생활시설 종사자의 근로실태, 작업 중 재해 및 그 처리 실태를 살펴보았고, 이와 관련된 법률들을 분석하였다. 재해 및 안전실태를 분석한 결과, 사회복지 생활시설 종사자들이 가장 흔하게 겪는 질환은 염좌․인대파열, 근골격계 질환이었다. 이 질환에 대한 산재 승인율은 원인에 따라서 달랐다. 업무상 사고의 경우는 승인율이 높았지만, 업무상 질환의 경우는 승인율이 낮았다. 다른 질환의 경우도 재해로 인한 경우는 산재 승인율이 높았지만, 업무상 질병으로 인한 경우는 승인율이 낮았다. 본 연구에서는 사회복지 생활시설 종사자의 안전하고 건강한 근무환경 조성을 위하여 다음과 같이 제언하였다. 첫째, 종사자의 산재보험 신청건수와 승인률이 높아져야 한다. 이를 위해서 중대재해만을 시설평가에 반영하고, 업무상 사유에 대해서 포괄적으로 해석해야 한다. 둘째, 산업안전보건법에서 사회복지시설에 대한 보건조치 항목을 확대 적용하고, 근로기준법에서 사회복지사업에 대한 근로시간 및 휴게시간의 특례 규정을 폐지해야 한다. 셋째, 사회복지사업법에서 시설특성에 맞춘 안전교육, 산재보험법․노동법 교육을 보수교육에 포함시키도록 해야 한다. This study investigated the working conditions, the occurrence and the treatment of industrial accidents of care workers in social welfare residential facilities and analysed the laws and regulations in related with social workers’ health and safety. The results of analysis showed the most frequent diseases are muscular skeletal diseases as bruises and sprains. but the rate of approvement for industrial accident compensation insurance benefits are different from causes. The approvement of accidents at work was high but that of diseases was low. To afford working conditions which employees could work healthy and safety in residential facilities, suggestions of this study are followings. First, to extend application for industrial accident compensation insurance benefit and standard for recognition of occupational accidents, penalty for ordinary industrial accidents and injuries shouldn't be imposed in residential facilities with industrial disasters and it should be constructed the meaning of occupational causes comprehensively. Secondly, it should be extended health measures widely for caring workers and eliminated contracting-out for social worker and business places under 5 workers in Industrial Safety and Health Act and in Labor Standard Act. Finally, laws for health, safety and industrial accident, labor should be contained in continuing education with property of in social welfare residential facilities. Key words : caring service, residential facilities in social welfare, social worker in caring, industrial accident, industrial accident compensation insurance act

지속가능한 BSC를 사용한 그린 IT 전략 실행과제들의 평가

박정선 대한안전경영과학회 2017 대한안전경영과학회지 Vol.19 No.3

Performance evaluation has been done using financial indices which are generally regarded as inappropriate for the organizations which are innovative and progressive. Thus, the Balanced Scorecard(BSC) was developed considering long term performance and invisible performance. This BSC has four perspectives of finance, customer, internal operation, and learning. Based on the BSC, a new BSC has been derived with a fifth view of environmental and social perspective, which is now called as a Sustainability BSC. In this study, we evaluated Green IT initiatives using the Sustainability BSC. The initiatives are categorized as RFID, telepresence, paperless office, logistics management etc. The initiatives were evaluated from the view of five perspectives, resulting in high cor relationships among finance, internal operation, and environmental and social perspectives. Namely, good initiatives from the view of environmental/social perspective are also evaluated as good from the view of finance and internal operation perspectives. In this study, we recommend organizations to introduce Green IT initiatives by showing how Green IT initiatives have contributed to the organizations.

청소년의 긴장감, 사회유대감, 비행친구와의 차별적 접촉이 청소년 지위비행에 미치는 영향

박정선,황성현 한국청소년학회 2013 청소년학연구 Vol.20 No.10

The purpose of this study is to evaluate three criminological theories including Sutherland's differential association theory, Agnew's general strain theory, and Hirschi's social bonding theory and which one is the best predictor of the causes of adolescents' status offenses in Korea. The data derived from a sample of 2,280 middle school students taken from national Youth Policy Institute in 2009-2010. Multiple OLS regression analysis revealed that variables from differential association theory were strongly supported as an explanation for adolescents' status offenses, while variables from general strain and social bonding theory were not supported. When differential association variables are excluded from the full equation model, the change in R2 is rapidly down, explaining that differential association variables are the best impact on dependent variables than other theories. The important implication of this study is that it is the first study to test three major theoretical models of adolescents' status offenses in Korea 우리 사회에서 청소년 지위비행은 청소년 시기에 흔히 발생할 수 있는 비행 중 하나이다. 특히 비행이론에 근거한 청소년 지위비행의 원인을 규명하려는 연구는 많지 않다. 이를 위해 본 연구에서는 최근 가장 많이 검증되고 있는 차별접촉이론, 일반긴장이론, 사회유대이론을 사용하여 한국 청소년 지위비행의 원인을 밝히는 작업을 수행하였다. 연구 자료는 한국청소년정책연구원에서 2009년과 2010년에 수집한 한국아동․청소년패널조사 중1과 중2 자료를 사용하였다. 다중회귀분석결과, 사회유대이론과 일반긴장이론의 변인들은 청소년 지위비행 변량의 2.9%와 3.5%만을 설명했지만 차별접촉 변인들은 지위비행 변량을 16.3%를 설명함으로써 가장 설명력이 뛰어난 것으로 드러났다. 특히 통합회귀분석 모델에서 차별접촉 변인들이 통합모델에서 제외될 때 회귀방정식의 결정계수가 현격하게 떨어지는 것을 발견함으로써 차별접촉 변인들이 청소년 지위비행을 가장 잘 설명한다는 사실을 밝혀냈다. 본 연구는 청소년 지위비행을 잘 설명할 수 있는 세 가지 비행이론을 적용하여 한국 청소년 지위비행의 원인을 파악했다는 점에서 중요한 의미를 지닌다. 특히 차별접촉이론의 친구와의 차별적 접촉변인이 지위비행을 가장 잘 설명함으로써 차별접촉이론에서 제시하는 지위비행 예방프로그램이 우리 사회에서도 큰 효과를 거둘 수 있다는 사실을 암시했다.

What is World Dance?

박정선 한국무용예술학회 2015 무용예술학연구 Vol.53 No.2

What does “world dance” mean? Is traditional dance that has been transformed into new dance forms still valuable as world dance or does it lose its authenticity? This study takes critical approach to the subject matter and investigates the different versions of “world dance” definitions by examining literatures. It is found that the term world dance often includes an examination of such complex issues as culture and diversity, accompanying the issues of racism and equality. However, the fundamental argument in regards to the terms of “global dance,” “world dance”, and “multiculturalism” is thateducators need to see global societies with local eyes. Rather than celebrating a homogenized culture and perspective, dancers and dance educators should find a way to serve profusion of individuals' voices and at the same time to bridge the gap between the students’ cultural boundaries.
