Background: Previous studies that have focused on the challenges faced by female surgeons, such as the gender pay gap, gender biases, lower likelihood of promotion, and gender differences in the perception of discrimination against women, are reviewed. A more comprehensive understanding of explicit and implicit gender discrimination and experiences and perceptions of discrimination is needed. This study aims to determine the current prevalence and degree of gender discrimination in the Korean Surgical Society and to compare the experiences and perceptions of gender discrimination between male and female surgeons. Methods: We analyzed 400 responses from a survey sent to all members of the Korean Surgical Society. This electronic survey included 16 items on experiences of gender discrimination and 17 items on perceptions of gender discrimination. We conducted χ2 tests and binary logistic regression on the data regarding these experiences and perceptions of gender discrimination. Results: Adjusted analyses found that female surgeons were more likely to experience gender discrimination than their male counterparts across all categories of discrimination. Further, adjusted analyses showed that female surgeons were more likely to confirm the presence of gender discrimination than male surgeons. Conclusion: Female surgeons were more likely to experience implicit and explicit gender biases and discrimination throughout all stages of their career progression. We also discovered significant gender differences in the perception of gender discrimination, as well as the experience of it. Changing the male-dominated culture and raising awareness of gender biases and discrimination among male surgeons are crucial steps toward addressing gender discrimination in surgery.

Effects of Unilateral Lower-extremity Joint Cooling on Movement Biomechanics during Two-legged Jumping and Landing

Choi Jihyeon,송경택,김훈,이세용,박지홍 대한운동학회 2022 아시아 운동학 학술지 Vol.24 No.2

OBJECTIVES This study examined the immediate effect of unilateral ankle or knee joint cooling on the low-erextremity kinematics and kinetics during two-legged jumping and landing. METHODS Twenty healthy adults randomly completed three data collection sessions for ankle or knee joint cooling, or control. For each session, participants performed two-legged countermovement jumps and lands. For joint cooling, two ice bags were directly placed to the right side and secured with a compression bandage. A three-dimensional motion analysis system (200 Hz) with two floor-embedded force platforms (2000 Hz) was employed to capture the jumping and landing. The cooling effects on kinematical (flight time, and sagittal plane joint angles) and kinetical (peak vertical ground reaction force (vGRF), impulse, and sagittal plane joint moments) variables were examined. A mixed-model analysis of variance was performed for each dependent variable (<i>p</i>≤0.0001 for all tests). RESULTS We did not observe any interactions (flight time: F_2,95=0.67, <i>p</i>=0.52; joint angles: F_2,209≤2.26, <i>p</i>≥0.10; peak vGRF: F_2,209≤1.76, <i>p</i>≥0.20; impulse: F_2,209≤2.54, <i>p</i>≥0.10; joint moments: F_2,209≤4.80, <i>p</i>≥0.01 for all interactions). Regardless of condition and time (side effect), subjects showed a dominant-leg predominant movement strategy. Specifically, the right side showed a greater peak vGRF (2%), and greater ankle (7%), knee (6%), and hip (11%) joint moments, as compared with the left side during jumping. The same movement pattern was observed during landing that there was greater peak vGRF (11%) and impulse (8%), and greater ankle and knee joint moments (15%). Regardless of time and side (condition effect), subjects with ankle joint cooling showed 5% lesser ankle joint moment during jumping, compared with those who received knee joint cooling (<i>p</i>=0.0001). CONCLUSIONS A 20-min of unilateral ankle or knee joint cooling seems to neither alter vertical jump height nor change movement biomechanics during two-legged jumping and landing.

This study aims to compare, analyze, and examine the differences in policies regarding the Palestinian refugees in Jordan, Lebanon, and Syria, focusing on the legal status of the refugees and the patterns of the conflict they experience in the host country. The Palestinian refugees have settled in different parts of the world in various forms, depending on the policies and stance toward them of the host country. Those in Jordan have been granted citizenship and enjoyed the same rights and benefits as Jordanian citizens under the favorable policies of the Jordanian government. On the other hand, Those in Lebanon live in an extremely restricted environment, being considered a threat to national security and stability. In Syria, they had received citizenship, rights, and benefits equivalent to Syrian citizens, excluding suffrage, but the Syrian civil war in 2011 has put them in a precarious situation. Sometimes, the Palestinian refugees cause conflicts within the host countries, regardless of their legal status and the environment they live in. In Lebanon, Palestinian resistance and armed groups, primarily based in the refugee camps, stand against Lebanese government forces and Israel. In Syria, the Palestinian refugees have been attacked by Syrian government forces, rebels, and the Islamic State (IS) as a direct impact of the Syrian civil war. Although the Palestinian Jordanians have a stable status compared to those in the other two countries, the conflict between and discrimination against the Transjordanian and those of Palestinian origin have escalated since the Black September, a series of clashes between Palestinian resistance and the Jordanian governments in 1970. By comparing and examining the situations of the Palestinian refugees in Jordan, Lebanon, and Syria, this study seeks to contribute to assessing the actual lives, non the fragmentary appearances of them, of the Palestinian refugees and enhancing the understanding of the Palestinian refugee group and communities.

최지현(Choi, Jihyeon),조미형(Cho, Mihyoung),이승영(Lee, Seongyoung) 한국사회복지학회 2022 한국사회복지학 Vol.74 No.2

본 연구는 한국 청년의 사회적 고립을 측정하는 척도 개발을 목적으로 하였다. 사회적 고립에 대한 선행연구 검토와 국내외 기존 척도 현황 조사 결과를 토대로 척도의 문항 개발 틀을 두 축으로 구성하였다. 관계의 종류 축은 사회적 관계의 수준에 따라 가족, 친구, 일, 사회, 공통으로 구분하고, 관계의 주관성 수준 축은 관계의 양, 관계에 대한 인식, 관계에 대한 감정으로 구분하였다. 기존 척도 문항을 문항 개발 틀에 배치하고, 전문가 검토를 거쳐 예비문항을 도출하였다. 2021년 11월 12일~24일에 온라인 설문조사를 실시하고, 서울시 거주 19세 이상 34세 이하 청년 631명의 응답을 분석에 사용하였다. 탐색적 요인분석과 확인적 요인분석을 통해 6개 하위요인 25문항이 도출되었다. 하위요인은 사회적 접촉, 정체성 불안, 가족 관계, 친구 관계, 일터에서의 관계, 사회적 지원으로 분류되었다. 척도의 신뢰도 검증에서 내적일관성, 하위요인별 신뢰도, 검사-재검사의 급내상관계수 등이 적절한 것으로 나타났으며, 유관 측정도구와의 상관분석을 통해 수렴타당도를 검증하였다. 마지막으로 청년의 사회적 고립 척도 개발의 의의와 후속연구를 위한 제언을 논의하였다. This study aims to develop a measure of social isolation among young adults in South Korea. The authors constructed two axes of measurement development frame based on the review of previous studies on social isolation and the survey of existing scales of social isolation. The first axis is the types of relationships. This axis has five subdimensions-family, friends, work, society, and common-which are categorized based on the levels of social interactions. The second axis, the degree of subjectivity of relationships has three subdimensions-quantity of relationship, perception of relationship, and emotion about relationship. The authors placed measurement items from existing scales on the measurement development frame with the two axes and derived preliminary items through interviews with subject matter experts. Subsequently, an online survey was conducted from November 12 to 24 in 2021, and responses obtained from 631 young adults aged 19 to 34 living in Seoul were used for analysis. 25 items in 6 subfactors are selected through exploratory and confirmatory factor analyses. These subfactors are; social contact, identity anxiety, family relationship, relationship with friends, workplace relationships, and social support. Internal consistency, subfactor reliability, and intraclass correlation coefficient of test-retest were appropriate. The authors verified convergence validity through correlation analyses with extant measures of similar concepts. The authors provide discussion of significance of the social isolation measurement scale development for young adults and suggestions for follow-up studies.

성폭력 피해자가 경험한 성폭력 피해에 대한 가족의 반응 : 잠재프로파일분석(LPA)의 적용

최지현(Choi, Jihyeon),김재엽(Kim, Jae-yop) 한국가족학회 2019 가족과 문화 Vol.31 No.4

본 연구는 성폭력 피해자들이 성폭력 사실을 가족에게 알렸을 때 경험한 가족의 반응을 탐색하고, 가족의 반응이 성폭력 피해 후유증에 미치는 영향을 살펴보는 것을 목적으로 하였다. 이를 위해 심한 성추행, 강간미수 및 강간의 성폭력 피해 경험이 있으며 가족에게 성폭력 피해를 알린 경험이 있는 88사례를 분석하였다. 연구결과 성폭력 피해를 알렸을 때 가족의 반응은 3개 잠재계층-반응이 약하고 변화가 적음, 고수준의 긍정적 반응, 적극적인 형태의 부정적 반응-으로 분류되었다. 이들 잠재계층간의 성폭력 피해 후유증에는 명확한 차이가 있었으며, 특히 성폭력 피해를 알았을 때 가족이 ‘반응이 약하고 변화가 적은’ 집단의 후유증이 가장 약하고, ‘적극적인 형태의 부정적 반응’을 보인 집단의 후유증이 가장 심했다. 연구결과를 바탕으로 성폭력 피해자가 경험한 가족 반응의 양상, 가족 반응의 중요성, 성폭력 피해자 지원에서 가족으로 지원 영역을 확대할 필요성을 논의하였다. This study aims to explore family reaction toward disclosure of sexual assault experience by the victims and examine the effect of family reaction on victim’s sequelae. The authors analyzed 88 victims’ cases with experience of sexual assault and disclosing the assault to the family. The analysis discovered that the family reaction toward the disclosure can be categorized into three latent classes and the three groups corresponding to these classes showed distinctly different sequelae patterns. The authors discuss patterns of family reaction experienced by the victims, the importance of family reaction, and the necessity of expanding the focus of public policy from supporting individual victims to supporting the family.
