세계 경제의 환경 변화로 제조업 부문은 경쟁 압력과 함께 구조조정 압력에 직면하고 있다. 특히, 석유화학 산업은 대표적인 장치산업이란 특징으로 인해 중국과 중동의 대규모 신규 설비투자가 한국 석유화학 산업에 커다란 구조조정 압력으로 작용하고 있다. 정부가 정책대안의 1순위로 꼽는 인수합병 계획으로 인해 대규모 고용조정과 함께 비정규직 증가가 초래될 가능성이 크다. 석유화학산업의 고용형태는 '핵심-주변'으로 이원화되어 있으며 '구조조정 = 비정규직 증가'로 나타나고 있기 때문이다. 프랑스의 구조조정 대응 사례를 통해 정부의 능동적 개입과 노조의 적극적 대안 추구 노력이 구조조정에 따른 고용 문제의 해결책을 마련해 낼 수 있음을 알 수 있다. 정부는 석유화학산업의 당면 과제인 산업 내 양극화를 극복하고 산업연관체계를 재구축하기 위한 능동적 역할을 담당해야 한다. 또한 지역차원의 고용안정시스템의 구축을 위해 지방정부의 능동적 역할이 요구된다. 특히, 도급구조로 이원화된 노동력 구조를 극복하기 위해서 건설플랜트노동자를 비롯해 하청구조 하의 다양한 비정규직의 이해를 반영하는 교섭틀 구축이 중요하다. 노동조합은 전체 노동자를 포괄하는 위치에서만 산업정책에 대한 개입력을 높여나갈 수 있다. 사회연대적, 사회운동적 노동조합주의라는 새로운 정체성 하에서만 적극적인 산업재편 개입전략의 토대를 형성할 수 있다.

Causal questions are prevalent in scientific research, for example, how effective a treatment was for preventing an infectious disease, how much a policy increased utility, or which advertisement would give the highest click rate for a given customer. Causal inference theory in statistics interprets those questions as inferring the effect of a given intervention (treatment or policy) in the data generating process. Causal inference has been used in medicine, public health, and economics; in addition, it has received recent attention as a tool for data-driven decision making processes. Many recent datasets are observational, rather than experimental, which makes the causal inference theory more complex. This review introduces key concepts and recent trends of statistical causal inference in observational studies. We first introduce the Neyman-Rubin's potential outcome framework to formularize from causal questions to average treatment effects as well as discuss popular methods to estimate treatment effects such as propensity score approaches and regression approaches. For recent trends, we briefly discuss (1) conditional (heterogeneous) treatment effects and machine learning-based approaches, (2) curse of dimensionality on the estimation of treatment effect and its remedies, and (3) Pearl's structural causal model to deal with more complex causal relationships and its connection to the Neyman-Rubin's potential outcome model.

The purpose of this study is to examine how SMEs' perception of organizational support affects turnover intention, and to investigate the moderating effect of abusive supervisionin the relationship between organizational support perception and turnover intention. As a result of the analysis of the study, First, it was confirmed that organizational support perception had a negative (-) effect on turnover intention. Second, the higher the organizational support awareness, the lower the turnover intention, but when the abusive supervision in intervened, it was found that the organizational support perception offsets the effect that reduces the turnover intention again. That is, emotional support, turnover intention still appeared even if the abusive supervisionin was involved, but instrumental support had no effect on turnover intention when the abusive supervisionin was involved. This study is meaningful in that it expanded the scope of manufacturing services, semiconductors, and IT industries of SMEs with high turnover intentions.

The purpose of this study was to determine the effectiveness of social work intervention for the family caregivers of the older persons with stroke. Twelve caregivers were assigned to either a treatment group or a control group. The treatment group intervention consisted of 8 weekly, 2-hour sessions which included education, peer and professional support, individual counselling. Wilcoxon test of the pretest and posttest scores of the two groups showed that those in the treatment program experienced significant decrease in caregiving burden and loneliness compared with caregivers who received no intervention. They also experienced increase in self-esteem, self-efficacy in dealing with caregiving tasks, satisfaction with a relationship with the care-receiver, emotional support. Most of these intervention effects were maintained in the 3-month follow-up measurement except loneliness and the caregiver-carereceiver relationship. Caregivers in the treatment group showed overall satisfaction with the program and willingness to continue to attend in the interventions. Based on these findings, implications for social work practice including self-help groups, psychotherapy for the caregivers, expanding social work intervention for the family caregivers of the older persons were discussed.

The predominant concern of the study consist in: (1) the direct effect of social commitment on teachers' intervention efficacy for helping both victims and offenders in school violence situation; (2) the indirect effects of both teachers' perceptions of offenders and victims, and fairness of school regulations on teachers' intervention efficacy. Research is based on a survey conducted with 351 teachers(84 males and 267 females) from 10 middle schools located in different districts of the city of Daegu. In order for subjects to verify research questions, structural equation models in teachers' intervention efficacy for helping both victims and offenders were explored. In order to verify the difference between mediators' effect, along with total indirect effect and each individual mediator's effects, bias-corrected bootstrapping analysis by using Mplus were employed. The major findings of the study supported the significance on direct effect of social commitment, and indirect effect of both fairness of school regulations and teachers' perceptions toward offenders and victims, on teachers' intervention efficacy. However, the indirect effect of fairness of school regulations(.025) was far outweighed by teachers' perceptions(.224) toward offenders and victims. In conclusion, the above findings claim our attention in that they provide a range of practical implications for teachers and other related professionals including school workers who are engaged in helping out both victims and offenders in school violence situation.

The purpose of this study was to identify the effect of gesture and facial expression on persona effects. Fifty-six college students were recruited for this study, and non-verbal communication skills were applied to a pedagogical agent with gesture (conversational vs. deictic) and facial expression. The conversational gesture may have relationship with social interaction hypothesis of pedagogical agent while the deictic gesture may have relationship with attentional guidance hypothesis. The facial expression can be assumed to facilitate the social interaction between the pedagogical agent and learners. Interestingly, the conversational gesture group showed a tendency of outperforming the deictic gesture group. It may imply that the social interaction theory has a strong impact on cognitive support as well as social interaction for learners. There was a significant interaction effect on the engagement when both of facial expression and conversational gesture were applied. This result has two implications. First, facial expression can facilitate the persona effect for engagement.

The objective of this study was to determine the effect of a psycho-educational group intervention in reducing psychologic distress and enhancing coping in Korean breast cancer patients. The patient selection criteria were age younger than 70 years, having any postoperative adjuvant therapy, and surgery undergone within the previous 12 months as of the start of the study and there were 70 patients eligible for this criteria. They were randomized into three groups; experimental group(24 patients), wait-list control group(24 patients) and wait-list group(36 patients). We conducted a 8-week, structured, psychosocial group intervention, which used psycho-educational strategies combining education and psychological support. Subjects were assessed for psychological distress and coping by administering the Beck Depression Inventory(BDI) and the Ways of Coping Checklist-Revised(WCCL-R) at the baseline and after 8 weeks. Forty eight patients were participated and thirty five patients completed the study. The experimental group had significantly lower scores than the controls for depression on the BDI(p=.012) after 8-week intervention. However, coping did not show a significant difference on WCCL-R after the intervention. Despite of some limitations, the results of this study suggest that a short term psychosocial group intervention produces a significant improvement in the quality of life of patients with primary breast carcinoma in Korea in terms of managing depression.

The use of alcohol is recognized as having negative consequences on clinical and psychosocial outcomes in service users with major mental illnesses. This necessitates an introduction of intervention measures in domestic mental health service in Korea. Since research basis on which such measures are developed lacks, this paper aims at exploring drinking patterns of Korean service users and suggesting directions and strategies for intervention. The data came from 151 service users recruited at 14 service settings in Seoul Metropolitan area. The quantitative part of the data includes their recent drinking experiences in terms of patterns and severity; the qualitative part includes information on the drinking context. The data were compared among three types of service settings, each of which differs in physical availability of alcohol by their users. Each group revealed distinctive features in drinking patterns, the author thus suggested directions and strategies of intervention specific to type of service setting.

This study is designed to verify the actual effect on the prevention of the elderly suicide of the integrated crisis intervention service which has been widely provided across all local communities in Gyeonggi-province focusing on the integrated crisis intervention model developed for the prevention of elderly suicide. The integrated crisis intervention model for the local communities and its manual were developed for the prevention of elderly suicide by integrating the crisis intervention theory which contains local community's integrated system approach and the stress vulnerability theory. For the analysis of the effect, the geriatric depression and suicidal ideation scale was adopted and the data was collected as follows; The data was collected from 258 people in the first preliminary test. Then, it was collected from the secondary test of 184 people after the integrated crisis intervention service was performed for 6 months. The third collection of data was made from 124 people after 2 or 3 years later using the backward tracing method. As for the analysis, the researcher used the R Statistics computing to conduct the test equating, and the vertical scaling between measuring points. Then, the researcher conducted descriptive statistics analysis and univariate analysis of variance, and performed multi-level modeling analysis using Bayesian estimation. As a result of the study, it was found out that the integrated crisis intervention model which has been developed for the elderly suicide prevention has a statistically significant effect on the reduction of elderly suicide in terms of elderly depression and suicide ideation in the follow-up measurement after the implementation of crisis intervention rather than in the first preliminary scores. The integrated crisis intervention model for the prevention of elderly suicide was found to be effective to the extent of 0.56 for the reduction of depression and 0.39 for the reduction of suicidal ideation. However, it was found out in the backward tracing test conducted 2-3 years after the first crisis intervention that the improved values returned to its original state, thus showing that the effect of the intervention is not maintained for long. Multilevel analysis was conducted to find out the factors such as the service type(professional counseling, medication, peer counseling), characteristics of the client (sex, age), the characteristics of the counselor(age, career, major) and the interaction between the characteristics of the counselor and intervention which affect depression and suicidal ideation. It was found that only medication can significantly reduce suicidal ideation and that if the counselor's major is counseling, it significantly further reduces suicidal ideation by interacting with professional counseling. Furthermore, as the characteristics of the suicide prevention experts are found to regulate the intervention effect on elderly suicide prevention in applying integrated crisis intervention model, the primary consideration should be given to the counseling ability of these experts.
