청소년의 친사회적 행동에 대한 또래집단의 영향력 검증

김학령(Hak Lyoung Kim),김정화(Jeong Hwa Kim),정익중(Ick Joong Chung) 한국아동복지학회 2011 한국아동복지학 Vol.- No.36

본 연구는 청소년이 바람직한 사회구성원으로서 성장하기 위해 필요한 요소로서 타인에 대한 배려와 돌봄의 행위인 친사회적 행동에 주목하였다. 또래집단의 영향이 청소년의 친사회적 행동에 어떻게 작용하고 있는지 알아보기 위해 또래영향모델과 개인특성모델을 중심으로 분석하였다. 보건복지부의 "아동청소년종합실태조사" 자료를 위계적 다중회귀분석으로 검증한 결과, 청소년의 친사회적 행동은 친구의 친사회적 행동으로부터 긍정적인 영향을, 친구의 반사회적 행동으로부터 부정적으로 영향을 받았다. 개인특성 요인인 자아존중감, 공감능력 변수를 포함한 모형에서는 공감능력, 자아존중감, 친구의 친사회적 행동, 그리고 친구의 반사회적 행동 순으로 청소년의 친사회적 행동에 통계적으로 유의미한 결과를 보였다. 따라서 또래영향모델과 개인특성모델이 모두 유효하나 개인특성의 영향이 더 큰 것으로 검증되었다. 또한 개인특성과 또래특성 간의 상호작용효과를 살펴본 결과, 자아존중감이 높은 경우 친구의 친사회적 행동이 본인의 친사회적 행동에 미치는 긍정적인 영향이 더 크고, 공감능력이 높은 경우 친구의 반사회적 행동이 본인의 친사회적 행동에 미치는 부정적인 영향이 더 적은 것으로 나타났다. 청소년의 친사회적 행동에 대한 또래집단의 영향력은 개인특성에 의해 영향을 받는 것으로 나타나, 또래영향모델과 개인특성모델은 청소년의 친사회적 행동에 상호보완적으로 작용하고 있는 것으로 검증되었다. 마지막으로 청소년의 긍정발달을 위한 사회복지적 함의를 논하였다. This study focuses on adolescent prosocial behavior as one of the necessary elements for youth to grow as a healthy member of the society. The purpose of this study is to examine the effects of peer group on adolescent prosocial behavior by comparing the peer influence model and the individual characteristics model. For the study, we conducted hierarchical multiple regression analyses using the data from the Korean Youth General Survey 2008, administered by the Ministry of Health and Welfare. Results show that friends` prosocial behavior had a positive impact, but friends` antisocial behavior had a negative impact on adolescent prosocial behavior. When individual characteristics including self-esteem and empathy were analyzed simultaneously, empathy, self-esteem, friends` prosocial behavior, and friends` antisocial behavior were found to be statistically significant. The strength of association between individual characteristics and adolescent prosocial behavior was greater than that of friends` behaviors. Also, significant moderating effects of individual characteristics on the relationships between adolescent prosocial behavior and friends` behaviors were found. For example, the positive effect of friends` prosocial behavior on adolescent prosocial behavior increased as adolescent`s level of self-esteem increased. On the other hand, the negative effect of friends` antisocial behavior on adolescent prosocial behavior decreased as adolescent`s level of empathy increased. Based on the findings, both the peer influence model and the individual characteristics model were considered valid in explaining prosocial behavior of Korean adolescents. Finally, implications of this study for positive youth development were discussed.

The comparison of the impact of arterial stiffness and central pressure on left ventricular geometry and diastolic function

김학령,Woo-Hyun Lim,Jae-Bin Seo,Sang-Hyun Kim,Zoo-Hee Zo,Myung-A Kim 대한고혈압학회 2019 Clinical Hypertension Vol.25 No.4

Background: This study was performed to compare the associations of brachial-ankle pulse wave velocity (baPWV) and central blood pressure (CBP) measurements with left ventricular (LV) geometry and diastolic function. Methods: A total of 77 subjects (64.5 ± 10.8 years, 67.5% females) without documented cardiovascular disease were prospectively recruited. All subjects underwent transthoracic echocardiography, baPWV and noninvasive measurement of CBP on the same day. Results: In simple linear correlation analyses, neither baPWV nor CBP was associated with LV mass index or relative wall thickness (P > 0.05 for each). Although baPWV significantly correlated with septal e´ velocity in simple linear correlation analyses (r = 0.258, P = 0.025), the significance was lost after controlling for potential confounder (P = 0.881). In simple linear correlation analyses, central systolic blood pressure (CSBP) and central pulse pressure (CPP) significantly correlated with both septal e´ velocity or E/e´ (P < 0.05 for each); however, neither central diastolic nor mean arterial pressures was associated with both septal e´ velocity and E/e´ (P > 0.05 for each). After controlling for confounders, including age, sex and body mass index, CSBP correlated with septal e´ velocity (β = − 0.258, P = 0.025), but not with E/e´ (P = 0.074). CPP correlated with both septal e´ velocity (β = − 0.300, P = 0.014) and E/e´ (β = 0.428, P = 0.002) in the same multivariable model. Conclusions: In subjects without documented cardiovascular disease, CSBP and CPP may be more strongly associated with LV diastolic function than baPWV. Further studies with a larger sample size are needed to confirm our results.

저자들은 수술 전 정맥혈전 예방을 하지 않은 고령의 대퇴골 경부 골절 환자에서 수술 중 발생한 심인성 쇼크로 발현된 우심방 혈전을 심초음파로 진단하였던 1예를 경험하였다. 우심방 혈전에 의한 폐색전증은 치명적이나 예방 가능한 질환으로 본 증례를 통하여 폐색전증 예방의 중요성을 강조하는 바이다. Venous thromboembolism is a relatively common condition in inhospital patients, but it may also manifest as a lethal disease. However, the diagnosis is not suspected clinically in the vast majority of cases. Most hospitalized patients are at risk of venous thromboembolism, but the risk can be reduced significantly by appropriate prophylaxis. We herein report a case of a huge right atrial thrombus that presented as sudden cardiogenic shock during bipolar endoprosthesis of the hip due to a femoral neck fracture. Although the patient was elderly and immobile for 3 days before hip surgery, she did not receive prophylaxis for venous thromboembolism. More attention should be paid to venous thromboembolism prophylaxis in high-risk patients. (Korean J Med 2013;85:83-86)

김혜미,김학령,Hak Seung Lee,정지현,Chee Hae Kim,Sooyeon Oh,Jung Ho Kim,조주희 대한심장학회 2014 Korean Circulation Journal Vol.44 No.3

Ante mortem cases of venous thrombosis in patients with nonbacterial thrombotic endocarditis (NBTE) have not yet been reported. We describea rare case of NBTE in a patient with mesenteric vein thrombosis. A healthy 37-year-old man with abdominal pain and fever underwentemergency small bowel resection due to bowel ischemia resulting from mesenteric vein thrombosis. Transthoracic echocardiographyrevealed multiple mobile masses attached to the anterior leaflet of the mitral valves and their chordae tendineae. On suspicion of infectiveendocarditis, the cardiac masses were excised through open-heart surgery. However, pathologic reviews were compatible with NBTE. Thepatient was stable after the cardiac surgery and was treated with warfarin. Laboratory and imaging findings regarding his hypercoagulablecondition were all negative.

Acute myocardial infarction often evolves from a mild coronary lesion. Therefore, the evaluation and management of intermediate coronary stenosis are important to prevent cardiac events. However, the decision on how to treat these lesions is challenging. Here, we report acute myocardial infarction occurring at a preexisting intermediate coronary stenosis based on invasive coronary angiography performed 10 days before the event.

신체건강행동 측정을 위한 척도개발연구

양옥경(Yang, Ok-Gyeong),김학령(Kim, Hak Lyoung) 한국사회복지학회 2015 한국사회복지학 Vol.67 No.3

본 연구는 사회복지실천 현장에서 보편적인 서비스를 이용하는 일반 클라이언트의 일상생활에서의 신체건강행동을 측정하기 위한 척도를 개발하는데 목적을 두었다. 문헌검토와 사회복지사 대상 FGI 및 관련 전문가의 내용타당도 검증을 거쳐 설문문항을 구성하였으며, 일반 성인 350명을 대상으로 설문조사를 시행하였다. 요인분석을 통해 ‘증진행동척도’와 ‘저해행동척도’의 하위척도로 나뉘는 ‘신체건강행동척도’를 완성하였다. 증진행동척도는 7요인(신체건강관리, 구강관리, 신체활동, 위생관리, 건강음식섭취, 수면관리, 식습관)으로, 저해행동척도는 5요인(흡연, 저해식품섭취, 음주, IT기기사용, 저해식습관)으로 구성되었다. 두 척도 모두 모형적합도가 우수하였고, 내적일관성 신뢰도 역시 높게 나타났다. 또한 수렴타당도, 판별타당도, 동시타당도 등의 검증에서 모두 유의미한 결과를 보임에 따라 타당성 있는 척도임이 확인되었다. 이렇게 개발된 척도는 사회복지실천의 현장에서 클라이언트에게는 신체건강행동에 대한 자기점검의 도구로, 사회복지사에게는 신체건강행동의 사정(Assessment)을 통한 근거기반의 실천을 할 수 있는 유용한 도구로 활용될 수 있을 것이다. This study aimed to develop a scale to measure physical health behaviors among social work clients using general services. The scale items were constructed based on literature review and FGI of social workers. Exploratory factor analysis and confirmative factor analysis affirmed the factor structure of Physical Health Behavior Scale with two sub-scales: Health Promotion Behavior Scale and Health Hindrance Behavior Scale. Promotion Scale had 7 factors and Hindrance Scale had 5 factors. Both sub-scales showed acceptable ranged goodness-of-fit for the model, and internal consistency test proved that the scale was reliable. The analyses of discriminant validity, convergent validity, and concurrent validity resulted significant validation. Based on those results, the developed Physical Health Behavior Scale were proved well-constructed, reliable and valid. The Scale will be utilized for both clients in general to check their own health related behaviors and social workers to adopt as a tool for assessment in order to perform an evidence based practice.
