다차원적 완벽주의와 청소년 수면의 관계 본 논문은 정은숙의 석사학위논문을 수정.보완한 것임 - 불안과 우울의 매개 효과 -
정은숙,안귀여루 한국청소년학회 2018 청소년학연구 Vol.25 No.2
본 연구는 다차원적 완벽주의와 청소년 수면의 관계에서 불안과 우울의 매개효과를 알아보고자 하였다. 이를 위해 경기도에 거주하는 고등학생 382명을 대상으로 다차원적 완벽주의 척도, 불안척도, 우울척도, 주간졸음척도, 불면증 척도를 사용하여 설문을 실시하였다. 연구결과, 첫째, 다차원적 완벽주의가 불면증에는 영향을 미치나 주간졸음에는 영향을 미치지 않는 것으로 나타났고 다차원적 완벽주의 하위변인 중 사회부과가 불면증에 영향을 미치는 것으로 나타났다. 둘째, 다차원적 완벽주의가 높을수록 불안과 우울도 높은 것으로 나타났으며 우울보다는 불안에 미치는 영향이 더 큰 것으로 나타났다. 셋째, 불안과 우울이 높을수록 주간졸음과 불면증도 높아지는 것으로 나타났다. 넷째, 불안과 우울이 다차원적 완벽주의와 불면증과의 관계를 완전 매개하는 것으로 나타났다. 이러한 결과는 다차원적 완벽주의가 높을수록 불면증이 심해지며, 다차원적 완벽주의로 인한 불면증을 관리하기 위해서는 정서적인 요인에 대한 개입도 필요함을 시사한다. The purpose of this study was to explore the mediatingeffects of anxiety and depression on the relationship between multidimensional perfectionism and adolescent sleep. For this, The survey research method was used to 382 high school students living in Gyeonggi Province. The finding of this study is as follows: First, the multidimensional perfectionism affects the insomnia but doen’t affect the daytime sleep, and the society imposition, one of the sub variables of the multidimensional perfectionism, affects the insomnia.Second, the higher the multidimensional perfectionism, the higher the anxiety and depression, and the bigger the impact on anxiety than the depression, the higher the results showed. Third, anxiety and depression turned out to be a mediating variable between multidimensional perfectionism and insomnia. The significances and limitations of this study were discussed.

Lipophorin (Lp) in the hemolymph of insects is known to selectively deliver lipids from sites of absorption or synthesis to sites of storage and utilization, such as the fat body, ovary and testis; however, no study regarding this has been reported in Galleria mellonella. In the present study, we examined the process by which Lp is taken up into the larval fat body, adult ovary and adult testis, and the transfer of lipid by Lp to these tissues in Galleria mellonella. To investigate the involvement of a receptor in Lp endocytosis, the larval fat body, adult ovary and adult testis were incubated for 1 h at room temperature with fluorescein isothiocyanate (FITC)-Lp, FITC-Lp plus unlabeled Lp, and FITC-Lp plus suramin, a receptor endocytic inhibitor. The amounts of FITC-Lp in the three tissues were significantly decreasedin the presence of unlabeled Lp and suramin, indicating that endocytosis of Lp by the tissues is mediated by a receptor. To examine the transfer of lipid by Lp, the tissues were incubated for 1 h at room temperature with 1,1′-dilinoleyl-3,3,3′,3′-tetramethylindocarbocyanine perchlorate (DiI)-Lp, DiI-Lp plus unlabeled Lp, and DiI-Lp plus suramin. The transfer of lipid by Lp was inhibited in the presence of unlabeled Lp and suramin, which is consistent with a receptor-mediated process. Our results show that the transfer process of lipid by Lp and uptake of Lp itself is by receptor-mediated endocytosis.
Lipophorin uptake by the larval fat body and adult ovary in the wax moth Galleria mellonella

Lipophorin (Lp) acts in the circulation of insects to selectively deliver lipids to target tissues. In the present study, we wanted to show that Lp is taken up into larval fat body cells and the adult ovary in Galleria mellonella . Larval fat body and adult ovary tissues were incubated at room temperature for 30 min with fluorescein isothiocyanate (FITC)-labeled Lp. Fluorescence microscopy and sodium dodecylsulfate (SDS)-polyacrylamide gel electrophoresis (PAGE) revealed that fat body and ovary tissues internalize fluorescence-labeled Lp. The results suggest that both lipids and proteins are taken up by fat body cells and the ovary and also that large amounts of proteins and lipids taken up can serve as building blocks and as a source of energy. Immunological relationships with other insects were investigatedusing western blotting. The data showed that the Lp of Galleria mellonellais related to that of Hyphantria cunea.
Humanitarian Intervention: Can It Be Perfect?
정은숙 사단법인 한국평화연구학회 2007 평화학연구 Vol.8 No.2
This article starts with a plethora of definitions of humanitarian intervention and then analyzes two post-Cold War international norms of humanitarian intervention vis-à-vis state sovereignty: individual sovereignty and responsibility to protect, proposed by Kofi Annan and Canadian government-led International Commission on Intervention and State Sovereignty respectively, which is followed by a review of six real world illustrations of humanitarian (non)intervention that the international community has run zigzag since the end of the Cold War, facing different sources and different types of humanitarian disasters occurring in different regions of the world: Somalia, Rwanda, Kosovo, Timor-Leste, Iraq, and Sudan. They are selected by the author due to the land-marking elements contained in them for us to get insights of future vision for humanitarian intervention: what should be and should not be done. After reviewing the six illustrations, what the author learned is that (i) a lesson learned from a certain humanitarian intervention would not be applied to different occasions; and that (ii) there would be no panacea to humanitarian crises, guaranteeing everything -- motivations, means, and both short- and long-term consequences -- good. Moreover, challenges to and cynicism on the emerging international norm favoring the humanitarian intervention do strongly exist today, which are dealt by the author in the end and the discussion of which is based on four themes, namely, selectivity, asymmetry, military force, and veto power.
