대학생의 내현적 자기애와 취업불안의 관계에서 학업적 자기효능감과 진로결정 자기효능감의 매개효과
김홍석,김정섭 한국청소년학회 2015 청소년학연구 Vol.22 No.2
본 연구는 목적은 대학생의 내현적 자기애와 취업불안의 관계에서 학업적 자기효능감과 진로결정 자기효능감의 매개효과를 알아보는데 있다. 지방대 대학생 259명을 대상으로 취업불안, 내현적 자기애, 학업적 자기효능감 및 진로결정 자기효능감 척도로 구성된 설문을 실시하였으며, 수집된 자료는 Preacher와 Hayes(2008)의 분석 절차에 따라 단순 매개효과와 다중 매개효과 분석을 실시하였다. 그 결과, 첫째, 단순 매개모형에서 내현적 자기애는 취업불안에 직접적인 영향을 미칠 뿐 아니라 학업적 자기효능감을 매개하여 취업불안에 영향을 미쳤다. 또한 내현적 자기애는 취업불안에 직접적으로 영향을 줄 뿐 아니라 진로결정 자기효능감을 매개하여 취업불안에 영향을 주었다. 둘째, 다중 매개모형에서 내현적 자기애는 취업불안에 직접적인 영향을 미쳤으며, 학업적 자기효능감을 매개하여 취업불안에 영향을 미쳤다. 하지만 내현적 자기애는 진로결정 자기효능감을 매개하여 취업불안에는 영향을 미치지 않는 것으로 나타났다. 끝으로 후속연구를 위한 제언을 하였다. The purpose of this study was to investigate the mediating effect of academic self-efficacy and career decision making self-efficacy on a relationship between covert narcissism and employment anxiety. The subjects of this study were 259 local undergraduate students. The instruments used in this study were scale for academic self-efficacy, career decision making self-efficacy, covert narcissism and employment anxiety. The procedures in Preacher and Hayes(2008) were used for testing simple and multiple mediation models to analyze the main data. As simple mediate models, the first results indicated that covert narcissism had a direct effect on employment anxiety, and academic self-efficacy mediated the relationship between covert narcissism and employment anxiety. Also, covert narcissism had a direct effect on employment anxiety, and career decision making self-efficacy mediated the relationship between covert narcissism and employment anxiety. Second, as multiple mediate models, covert narcissism had a direct effect on employment anxiety, and career decision making self-efficacy mediated the relationship between covert narcissism and employment anxiety. However, career decision making self-efficacy didn't mediate the relationship between covert narcissism and employment anxiety. In the discussion, we provided implications for counseling practice and further research.

Purpose: To compare spherical aberration, higher-order aberration, and contrast sensitivity of eyes implanted with aspheric (AcrySof IQ) or spherical (AcrySof Natural) intraocular lenses. Method: Seventy-five eyes implanted with posterior chamber intraocular lenses were divided into two groups: AcrySof IQ (35 eyes) and AcrySof Natural (40 eyes). Wavefront analysis (spherical, higher-order and total aberration) using iTace, and contrast sensitivity (under photopic and mesopic condition) using Optec 6500 were performed at 1 month and 3 months postoperatively. Result: One month after surgery, the IQ IOL (intraocular lens) group had lower values of spherical aberration (p<0.001) and higher-order aberration (p=0.048) than the Natural IOL group. The IQ IOL group also showed better contrast sensitivities at 1.5- and 3-cpd spatial frequencies in mesopic conditions. Three months after surgery, the IQ IOL group had less spherical aberration (p<0.001) and higher-order aberration (p=0.027) than the Natural IOL group and showed better contrast sensitivities at the 3-cpd spatial frequency in mesopic conditions. Conclusions: Aspheric AcrySof IQ IOL induced significantly less higher-order aberration and spherical aberration than AcrySof Natural IOL. The contrast sensitivity was better under mesopic conditions in the AcrySof IQ IOL-implanted group. J Korean Ophthalmol Soc 49(8):1256-1262, 2008
초등학교 고학년 학생의 부모애착이 또래관계에 미치는 영향에 있어서 탄력성의 매개효과

The purpose of this study was to investigate the mediating effect of resilience on the relationship between parents attachment and peer relationship in upper grade elementary school students. The subjects of this study were 490 students who were in the five or sixth grade in an elementary school in busan. The test tools were Parents attachment, Peer relationship and Resilience. The collected data were Correlation and Covariance structural equation modeling. The results of this study were as follows: First, the higher the parents attachment, the higher the resilience and the peer relationship. the higher the resilience, the higher the peer relationship. Second, the resilience partially mediated the relationship between the parents attachment and the peer relationship. Third, the mother attachment influence on peer relationship than father attachment by mediation of resilience. Possible reasons for these results were identified and discussed. 본 연구의 목적은 초등학교 고학년 학생의 부모애착과 또래관계에서 탄력성의 매개효과를 알아보는 것이다. 이를 위해 부산광역시에 소재한 3개 초등학교 5, 6학년 490명을 대상으로 부모애착, 탄력성, 또래관계에 대한 설문을 실시하였다. 그 결과, 첫째, 부애착과 모애착은 모두 탄력성, 또래관계와 정적인 상관이 나타났다. 또한 탄력성과 또래관계 간에도 정적 상관관계가 나타났다. 둘째, 부모애착이 또래관계에 미치는 영향에 있어서 탄력성의 부분매개모형이 적합한 것으로 나타났다. 셋째, 부애착과 모애착 중에 모애착이 탄력성을 부분매개하여 또래관계에 더 많이 영향을 주는 것으로 나타났다. 이 결과는 초기 청소년시기에 있는 초등학교 고학년 학생에게 부와 모의 역할이 모두 중요하지만 모의 역할이 상대적으로 더 중요한 변임임을 나타낸다.

Seminal vesicle cysts associated with ipsilateral renal agenesis are very rare, with most being congenital, and two-thirds associated with renal dysplasia or agenesis and ectopic ureter opening into the seminal vesicle. When they are symptomatic, surgical excision has been the treatment of choice. Herein, a case of a symptomatic giant seminal vesicle cyst associated with ipsilateral renal agenesis is reported, which was treated by laparoscopic excision. (Korean J Urol 2004;45:735-738)
