Prevention of biofouling and microbial contamination of implanted biomedical devices is essential to maintain their functionality and biocompatibility. For this purpose, polypept(o)ide block copolymers have been developed, in which a protein-resistant polysarcosine (pSar) block is combined with a dopamine-modified poly(glutamic acid) block for surface coating and silver nanoparticles (Ag NPs) formation. In the development of a novel, versatile, and biocompatible antibacterial surface coating, bl

This paper presents the results of evaporation experiments using water droplets on aluminum sheets that were either smooth or had surface structures at the micro-scale, at the nano-scale or at both micro- and nano-scales (dual-scale). The smooth surface was a polished aluminum sheet; the surface with micro- scale structures was obtained by sandblasting; the surface with nano-scale structures was obtained using conventional aluminum anodization and the surface with dual-scale structures was prepa

인터넷으로 시행한 BDI-2는 만족할만한 내적 일관성과높은 검사-재검사 신뢰도를 보였다. 또한 PHQ-9등의 다른 우울척도와도 유의미한 공존 타당도를 나타내어 우울증을선별하고 평가하는 데 있어서 지필검사와 동등한 신뢰도와타당도가 입증되었다. 이러한 결과가 앞으로 일반인을 대상으로 한 우울증 선별 검사와 우울증 관련 연구에 효과적으로사용될 수 있기를 기대한다.

Objectives：The objective of this study is to find out the differences in psychopathology, temperament, and character factorsbetween young adults with and without childhood attention-deficit hyperactivity disorder (ADHD) symptoms. Methods：The subjects consisted of 314 university students (male=72, female=242) in Gongju. They were divided into childhoodADHD group (N=54) and normal group (N=260) to the Wender-Utah Rating Scale. Participants were assessed using KoreanAdult ADHD Scale, Beck Depressio

본 연구는 성인 인구를 대상으로 체중을 인지하는 태도나체중 조절을 위한 노력과 자살사고의 관계를 평가했다. 남녀모두에서 체중을 인지하는 태도는 자살 사고에 영향을 주지못했으나 체중을 조절하기 위해 노력할 때 자살사고에 영향을 미쳤다. 이러한 점에서 볼 때 체중 조절을 위해 노력하는점은 자살을 평가하는 데 유용한 정보로 사용될 수 있을 것이다.

Oil retention experiments were conducted and the performance was characterized for electrochemically etched stainless steels. The 304 stainless steels were electrochemically etched in dilute Aqua Regia to form porous structures. The structures were also hierarchical, which provides very large area for oils to adhere. Also the structures had deep valleys, which act as reservoir and are able to resist against oil-detaching forces. Several commercial oils were dispensed to characterize oil retentio
