외상후 정체성 변화의 유형 구분 : 심리 증상, 외상 기억 표상과 심리 대처 양상의 차이

최현정,이훈진 한국인지행동치료학회 2017 인지행동치료 Vol.17 No.2

본 연구는 외상후 정체성 변화 유형에 관한 가설을 검증하고자 하였다. 외상 재료의 과잉 조절을 반영하는 정체성 과잉조절, 외상 재료의 과잉 동화를 반영하는 정체성 통합결여의 측정치를 기준으로, 두 측정치 모두 높은 해리 유형, 과잉조절만 높은 과잉조절 유형, 통합결여만 높은 외상억제 유형, 그리고 모두 낮은 통합 유형의 네 가지 유형을 구분하여 가설을 수립하였다. 이에 외상을 경험한 271명의 자료를 네 가지 유형으로 구분하여 외상 기억 표상, 대처 양상, 그리고 심리 증상의 차이를 살펴보았다. 해리 유형은 높은 수준의 심리 증상을 보이고, 감각기반 기억이 우세하며, 모든 부적응적 대처 수준이 높았다. 이에 비하여 과잉조절 유형은 외상 관련 부정적 평가가 높았고 반추와 보다 연관되었다. 외상억제 유형은 외상 재료의 회상이 분명하지 않은 심리 증상 및 해리성 대처 양상이 두드러진 유형으로 구분되었다. 통합 유형은 맥락 기억은 높은 동시에, 심리 증상, 감각기반 기억, 그리고 모든 부적응적 대처 양상에서 낮은 수준을 보였다. 마지막으로, 이러한 유형 구분에 따른 임상 진단에의 시사점과 유형별 치료 과정에 대해 논의하였다. This study was to verify the hypothesis on subtypes of identity change after trauma. Based on identity over-accommodation measures and identity disintegration measures, subtypes were divided into the dissociative subtype with both high over-accommodation and disintegration, over-accommodation subtype with only high over-accommodation, trauma-inhibition subtype with only high disintegration, and integration subtype neither high on both measures. Data from 271 participants with trauma experiences were divided into the four subtypes, and differences on trauma memory representations, coping strategies, and psychological symptoms among the subtypes were explored. Dissociative subtype showed high psychological symptoms with dominant sensation-based memory representations, with high levels in all maladaptive coping strategies, while over-accommodation subtype was more related to negative appraisals and ruminations about the trauma. Trauma-inhibition subtype was distinguished in psychological symptoms unclearly related to recollections of the trauma material, with high dissociative coping strategies. Integration subtype was related to high contextual memory representations, showing low levels in psychological symptoms, sensation-based memory representations, and in all maladaptive coping strategies. Implications for clinical diagnoses and suggestions for treatment according to the subtypes were discussed.

대학생의 낙관성과 삶의 이유가 자살생각에 미치는 영향

최현정,홍혜영 미래를 여는 청소년학회 2011 미래청소년학회지 Vol.8 No.4

This study examined how the optimism and reasons for living affects suicide ideation, and that whether reasons for living would mediate in the relationship between optimism and suicide ideation. The subjects consisted of 474 college students in seoul․gyong-ki do and geon-la do. For data analysis, the conducted to technical statistical analysis, correlation analysis, regression analysis, structure equational model analysis. The results are as follows. First, correlation analysis results of optimism, reasons for living, suicide ideation that suggested there was a significant positive correlation between optimism and reasons for living, and significant negative correlation between suicide ideation and optimism, reasons for living. Second, for the assessment of the impacts, simple regression analysis was carried out on the link between suicide ideation and optimism. It's turned out that optimism had significant negative impact on suicide ideation. Survival coping beliefs and responsibility to family had a significant negative impact whereas expectation to future had significant positive impact on suicide ideation. Simple regression analysis was conducted on the link between suicide ideation and sub-factors of reasons for living. Third, an examination of the mediating role of reasons for living between optimism and suicide ideation, revealed that the reasons for living completely mediates the relationship between optimism and suicide ideation. The results of this study should be useful in preparing more specific target interventions for preventing suicide among college students, and implication of there results for future research and limitation are discussed. 본 연구는 대학생의 낙관성과 삶의 이유가 자살생각에 미치는 영향을 탐색하고, 낙관성과 자살생각의 관계에서 삶의 이유가 매개역할을 하는지 알아보고자 하였다. 조사대상자는 서울․경기와 전라지역의 대학생 474명(남: 144명, 여: 330명)이었다. 자료 분석을 위해 기술 통계분석, 상관분석, 회귀분석, 구조방정식 모형검증을 실시하였다. 연구결과 첫째, 낙관성, 삶의 이유, 자살생각의 상관분석 결과, 낙관성은 삶의 이유와 정적상관을 나타냈다. 삶의 이유의 하위요인별 상관에서는 생존과 대처 신념, 가족책임, 미래기대와 정적상관을 나타냈다. 낙관성과 자살생각은 부적상관을 나타냈으며, 삶의 이유와 자살생각도 부적상관을 나타냈다. 자살생각과 삶의 이유 하위요인별 상관에서는 생존과 대처 신념, 가족책임, 미래기대 요인이 자살생각과 부적상관을 나타냈다. 둘째, 낙관성, 삶의 이유 그리고 삶의 이유의 하위요인이 자살생각에 미치는 영향을 알아보기 위하여 회귀분석을 실시한 결과, 낙관성은 자살생각에 부적 영향을 미치고, 삶의 이유 전체와 삶의 이유 하위요인인 생존과 대처 신념, 가족책임은 자살생각에 부적 영향을, 미래기대는 정적영향을 미치는 것으로 나타났다. 셋째, 낙관성과 자살생각의 관계에서 삶의 이유의 매개효과 모형을 검증한 결과, 낙관성이 삶의 이유를 완전매개하여 자살생각에 영향을 미치는 것으로 확인되었다. 끝으로 본 연구 결과가 대학생의 자살예방과 자살위기 상담에서 자살생각에 보호요인으로 적용될 시사점을 논의하였고, 연구의 제한점과 후속 연구를 위한 제언을 하였다.

Background: Anaplastic thyroid carcinoma has grave prognosis with most patient dying within 6 months of diagnosis. 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors have been reported to have an anticancer effect in experimental and clinical studies. In this study, we investigated the effect of HMG-CoA reductase inhibitors on cell growth, invasiveness, adherence and signal transduction to evaluate the possibility of simvastatin as an agent for treatment of thyroid cancer. Methods: The viability of simvastatin treated 3 thyroid cancer cell lines (FRO, WRO, and ARO) were determined. We evaluated the cell migration, anchorage-independent growth and invasion ability in anaplastic thyroid cell line. The expression and phosphorylation of focal adhesion kinase (FAK) and extracellular signal-regurated kinase (ERK) were determined by immunoblot analysis. Results: Three thyroid cancer cell lines showed concentration dependent decrease of viability after treatment with 100~200 mM of simvastatin. Anaplastic ARO cell line showed the most predominant decrease in viability. In ARO cell lines, cell migration was decreased by concentration dependent manner after treatment with simvastatin (concentration ≥ 5 mM). Anchorage independent colony formation also decreased after simvastatin (≥ 10 mM). Finally, immunoblot analysis revealed that the phosphorylation status of FAK and ERK decreased in time dependent manner following treatment with 10 mM of simvastatin. Conclusion: The results of this study suggest that simvstatin exerts a favorable effect on the progression and metastasis of thyroid cancer. However, further studies are needed to elucidate the related mechanisms and signal transductions prior to its therapeutic application.

Corporate Social Responsibility, Tax Avoidance, and Business Groups

최현정,우소희,변정윤 한국경영교육학회 2019 경영교육연구 Vol.34 No.2

[Purpose]The purpose of this paper is to examine the association between corporate social responsibility (CSR) performance and corporate tax avoidance in business groups (called Chaebols in Korea). [Methodology]The samples in this study are selected from a set of non-financial Korean listed firms over the period of 2002-2010. From the full sample, CSR and non-CSR firms are classified using Korea Economic Justice Institute (KEJI) index. [Findings]The result shows that tax avoidance decreases more in CSR firms than in non-CSR firms. Hosever, this negative association is significant not in Chaebol firms but in non-Chaebol firms. These results indicate that tax decision depends on whether or not firms are included in Business groups, so the CSR effect on tax avoidance is different with corporate governance of firms. [Implications]These findings are useful for tax policy makers, managers, and investors to acknowledge that involvement in CSR activities may not be able to limit manager’s opportunistic behavior when firms are heavily ownership concentrated and they are exposed to high agency risk.
