가정폭력 노출 아동의 공격행동 감소 프로그램 개발을 위한 참여연구

박형원(Hyung Won Park) 한국아동복지학회 2004 한국아동복지학 Vol.- No.17

우리 사회에서 심각한 사회문제로 대두되고 있는 가정폭력의 문제에서 부부폭력을 목격하거나 부모로부터 학대받음으로써 직·간접적으로 가정폭력에 노출된 아동의 문제에 대한 관심은 저조한 편이었다. 그러나, 가정폭력 노출 아동은 일반아동에 비해 행동, 정서, 신체, 인지의 문제가 있음이 밝혀지고 있다. 그 중 공격행동의 문제는 아동의 청소년기와 성인기에까지 안정적으로 유지되는 특성이 있고, 가정에서의 폭력적인 상호작용이 아동의 공격행동의 학습과 강화에 영향을 줄 수 있으며 나아가 폭력의 세대간 전승(intergenerational transformation of violence)을 야기할 수 있다는 점에서 중요하게 다루어져야 한다. 이러한 문제제기로부터 본 연구에서는 가정폭력 노출 아동의 공격행동 감소 프로그램을 개발하는 것을 목적으로 하였다. 이를 위해 프로그램 개발과정에서는 문헌연구와 현장 실무자들의 참여에 기초한 참여연구방법을 적용 하였다. 지역사회 공부방 교사들로 프로그램 개발을 위한 포커스 그룹을 구성하였고, 7회의 회합을 통해 대상 아동의 특성을 고려하면서 프로그램을 개발하였다. 특히 대상 아동의 특성으로 제시된 부정적인 자기인식, 정서·행동·사고의 문제, 대인관계에서의 공격적인 특성, 폭력에 대한 긍정적 태도, 가족이나 부모관계에서의 폭력 경험 등을 토대로 아동들의 부정적 정서와 폭력에 대한 왜곡된 인식, 공격행동의 대안, 가정폭력에 대한 인식변화와 대처 등을 프로그램의 주요 내용으로 구성하였다. 이 연구를 통하여 연구자와 참여자가 함께 지식의 습득과 생산과정에 참여함으로써 대상 아동의 특성에 적합한 프로그램 개발, 실무자의 교육과 의식개발, 동기화 효과를 거둘 수 있었다. 또한, 아동의 공격행동이라는 외현화 된 행동문제에 대하여 그 이면에 내포된 가정폭력으로 인한 부정적 정서와 가정폭력에 대한 인지적 평가의 변화를 통해 아동의 공격행동의 변화를 도모한 특징이 있다. 이는 가정폭력이라는 환경적 위험요인속에서 아동들이 가정폭력에 대한 인지적 평가를 변화시킴으로써 하나의 보호요인을 개발할 수 있도록 한다는 점에서 의미가 있다. 이 외에 가정폭력 노출 아동에 대한 연구 및 실천에 있어서 고려할 점을 제언하였다. Compared to the fact that family violence issues have been focused on in our society as a serious problem recently, there has been not enough studies on children who have witnessed marital violence or been abused by their parents; being exposed to family violence directly and indirectly. But, it is clear that the children exposed to family violence have problems in their behavior, emotion, and cognition. Among these problems, aggressive behaviors tend to stay stable through an adolescent period and adulthood. Also, violent interaction within the family can influence child`s aggressive behavior learning pattern and enforcement and further more it can cause intergenerational transformation of violence. Therefore aggressive behavior problem is a very important issue that should be dealt with thoroughly. By bringing up the above problems, this study develops aggressive behavior reducing program of the children who have been exposed to family violence. To develop the program, participatory research method has been applied based on document researches and field practitioner`s participation. Characteristics of the children exposed to family violence and aggressive behavior and its intervention methods were reviewed through literature review. Afterwards the researcher formed a focus group consisting community gongbubang teachers. Based on the children`s qualities; such as negative self perceptions, emotional / behavioral / thinking problems, aggressive characteristics in personal relations, positive attitude on violence and experience of family or marital violence; negative emotion, distorted recognition of violence, substitute of aggressive behavior and recognition change and coping of family violence were used as main contents of the program. Two significant factors could be drawn out by this study. First is that the in the process of program development participants have gained knowledge and toke part in the production procedure. The researcher could understand children`s qualities and also educate and develop the participants` self awareness and motivation. Second is that the program developed in this study is composed of anger management intervention of children`s aggressive behavior and family violence related factors, effecting children`s aggressive behavior changes through reducing negative emotion and cognition caused by family violence This is significant in the sense that by changing children`s cognitive appraisal on family violence in environmental risk factors, protective factors could be developed. A document of suggestions on the studies and practices of children exposed to family violence is attached.

HIV/AIDS 감염인과 일하는 사회복지사의 딜레마

박형원(Hyung Won Park) 한국사회복지실천연구학회 2020 미래사회복지연구 Vol.11 No.1

본 연구는 “HIV/AIDS 관련기관에서 일하는 사회복지사가 경험하는 딜레마는 무엇인가?”라는 연구질문으로 질적연구를 하였다. HIV/AIDS영역에서 1년 이상 근무한 사회복지사 7명을 심층인터뷰하여 수집한 자료를 분석하였다. 연구 참여자들은 HIV감염인을 만나면서 클라이언트와의 관계에서 존엄한 삶과 생명에 대한 가치의 흔들림, 클라이언트의 경험과 가치 차이에서 오는 갈등, 비밀보장의 딜레마를 경험하였다. 사회복지조직에서 일하는 사회복지사로서 한정된 자원사용 시 형평성의 딜레마, 자원확보와 클라이언트 보호에서의 딜레마, 조직의 규칙과 클라이언트 이익간의 갈등 속에서 균형을 이루고자 노력하고 있었다. 연구참여자들은 AIDS를 둘러싸고 있는 사회의 무관심 속에서 무뎌지지 않으려 노력하고, AIDS사업의 전달체계 안에서 실적중심의 성과요구, 한계가 있는 법과 제도를 따를 수 밖에 없지만 한편으로는 클라이언트를 위해 부단히 정부의 문을 두드리고 있다. 이러한 연구참여자의 경험들은 ‘무한반복하는 딜레마의 악순환 속에서 감염인을 중심에 놓고 일함’으로 범주화하였다. 이러한 딜레마 요인을 파악함으로써 미시적으로는 조직에서의 수퍼비젼 및 딜레마 논의체계구축, 사회복지사 교육과정에 윤리적 이슈에 대한 부분의 강화, 거시적으로는 AIDS에 대한 사회적 낙인 감소, 정부의 적극적인 대응을 제언하였다. The purpose of this study was to gain better understanding of social workers dilemma who work at HIV/AIDS organizations. In-depth interviews were conducted with seven social workers who had worked in HIV/AIDS agencies, and qualitative research method was used for analysis. The findings revealed that the workers experienced their value of life and human dignity being challenged, conflicts arising from differences in client s experience and values, and the dilemma of confidentiality. Within organizations, they were trying to balance the dilemma of equity in using limited resources, and of securing resources and protecting clients, and the conflict between organizational rules and clients’ interests. The participants tried not to be dull to society’s indifference to AIDS, they were also forced to follow performance-oriented demands, limited laws and systems of the AIDS project. Despite the difficulties, they continue to knock on the door of the government on their clients’ behalf. Their work experiences were categorized as ‘working with the clients in a vicious cycle of recurrent dilemmas’. Based on the findings, the following were suggested: the use of supervision system within organizations along with peer support group, promotion of HIV/AIDS in social work education, the government s active policy for and the reduction of social stigma against HIV/AIDS.

HIV/AIDS 관련기관 종사자의 소진과 회복경험

In order to discover the burn-out and recovery experiences of HIV/AIDS service providers, this study analyzed in-depth interview data from HIV/AIDS service providers using Giorgi’s phenomenological method. A total of 9 social workers and counselors working in various agencies participated in this research. This study came up with 24 meaning units such as ‘vague fear’, ‘being afraid to work’, ‘ignoring one’s concerns about work’, ‘consoling oneself’, ‘intention to remain as an appreciated person’, 5 sub-subjects such as ‘mixed feeling while working with clients living excluded lives’ and the main subject, ‘confirming oneself as a helping professional’. With the close interaction with clients who suffer from stigma, stereotypes and illness, HIV/AIDS service providers experienced a wide range of emotions, oscillated between exhaustion and recovery of passion, and secured their position as helping professionals. The results suggest individual and organizational interest in the management of workers’ stress and burnout as well as training for professional improvement. The findings are expected to be utilized for human resource management and employee supervision and support in HIV/AIDS-related social welfare organizations.

There is thixo-extrusion to form high strength aluminum alloy. But, it is a problem that grains become grain coarsening during reheating process because the alloy was exposed at high temperature. In order to solve grain growth during reheating process, calcium was added in Al-Zn-Mg alloys. Primary a grain sizes of semi-solid Al-Zn-Mg-(0, 0.4, 0.6 and 0.9, wt.%)Ca were measured with image analyzer after reheating. Measured primary a grain sizes were applied to LSW(Lifshitz-Slyozov and Wagner) equation to check the effect of Ca on grain coarsening. Coarsening rate constant K values of semi-solid Al-Zn-Mg-(0, 0.4, 0.6 and 0.9, wt.%)Ca alloys were 371 mm3s-1, 247 mm3s-1, 198 mm3s-1 and 166 mm3s-1, respectively. As increasing calcium content, K value decreased which means grains are refined. Also, grains of calcium addition were more spherical than that of calcium free.
