최근 hydroxystyrene을 기반으로 한 레진은 3D Nand 공정에 사용되는 후막용 포토레지스트와 페키징용 포토레지스트에 핵심 레진으로 사용됨에 따라 다시 주목을 받고 있는 소재이다. 본 레진의 제조 공정은 프리라디칼 중합방법, 음이온 중합방법 그리고 리빙 라디칼 중합방법으로 나눌 수 있다. 중합방법의 선정은 공중합 모노머 또는 사용 용도의해 결정된다고 할 수 있다. 본 발표에서는 레진의 중합 방법과 그에 따른 물성에 대해 다룰 예정이다.

When compact HVAC is applied to a building, various variables exist in performing the functions of air conditioning, ventilation, and hot water supply of the building, and various experimental and empirical evaluations according to the energy performance evaluation method of the building occur. We are going to present research data for preparing domestic evaluation standards for energy evaluation methods for compact HVAC and zero-energy buildings to be applied in the future.

This study aims to find the need for international design events by studying how international design events affect city branding in the host city. As a case analysis for this case selection was limited to design events that has been held continuously for more than 10 years with the global scale in terms of size and overcame the pandemic. It has selected the London Design Festival which has built a city brand through international design events for 20 years and the World Design Capital (WDC), which has successfully held design events in eight cities over the past 16 years. The research task is to explore how international-scale design events affect city branding. In order to achieve the research purpose this study first examines the essential purpose of design due to international design events on a theoretical basis and explores references and similar prior papers on the feasibility of city branding. Second, a case study of London Design Festival which is held in a city with a relatively long history and a high ranking of city brands first identifies the characteristics of successful exhibition events and examines the possibility of city branding of design events held every two years in different cities. As results of this study five factors that design events affect on city branding were extracted through comparative analysis of the two design events. The five elements are sociability, economy, culture, sustainability, and connectivity. The London Design Festival and the World Design Capital a world-class international design events that has been held for more than 16 and 20 years have found social and economic development potential through cooperation with cities in the host area influenced city regeneration and culturally promoted the pride of the host city. Furthermore, the sustainability of design-related institutionalization and the connectivity of online networks allow the world to share ideas further increasing the possibility of developing into a successful city branding.
Protective Effects of Silkworm Hemolymph Extract and Its Fractions on UV-induced Photoaging

Ultraviolet (UV) irradiation induces skin photoaging by generating reactive oxygen species (ROS). ROS caused by UV-irradiation results in loss of skin cells and degradation of extracellular matrix. A number of antioxidants have been chemically synthesized or naturally extracted to prevent ROS-mediated skin photoaging. In our previous work, silkworm hemolymph extract (SHEX) was prepared, and its antioxidant activity was tested by free radical-scavenging assay. This study assessed the protective effects of SHEX on UV-induced photoaging of human immortalized keratinocytes (HaCaT). UVA (365 nm)-induced ROS generation was inhibited by supplementation of silkworm hemolymph (SH). Treatment with SHEX prepared by boiling SH inhibited death of HaCaT cells caused by UVB (315 nm) and UVA irradiation in a dose-dependent manner. Seven fractions were obtained by separating SHEX by gel permeation chromatography and the antioxidant activity of the fractions was examined. The fraction showing the highest protective efficacy on UV-induced cell damage corresponded to the lutein-containing fraction isolated in our previous study. Moreover, the SHEX fraction suppressed the expression of MMP-1 (matrix metalloproteinase-1), a matrix-degrading enzyme, suggesting that the active constituent of SHEX has the potential to inhibit skin photoaging. These results suggest that SHEX can be developed as a dietary and cosmetic supplement for prevention of skin photoaging.
새천년개발목표(MDGs) 15년: 달성수준과 한국의 과제

본 연구에서는 유엔과 국제사회가 지난 14년간 진행되어 온 새천년개발목표(MDGs)에 대한 노력과 성과를 평가하고 한국의 과제를 고찰하였다. 새천년개발목표가 추구한 비전과 목표가 상당부분 달성되기 도 하였고, 여전히 미흡한 부분이 많이 있지만, MDGs의 여러 목표들이 국제사회의 일관된 의제로서 다 루어지고 각 주체별로 다양한 실현 노력이 이루어지는 정치적 계기와 발판이 되었고, 그러한 성과들이 계량적으로 측정, 비교되는 점에서 실제적으로 커다란 의의가 있다. 세계는 MDGs가 설정한 15년간의 경험과 시행착오를 바탕으로 향후 또 다른 개발 의제를 국제사회의 새로운 정책과제로 추진할 전망이다. 따라서 한국은 새로운 개발의제를 발판으로 명실공히 국제사회에서 신뢰받는 중추적 중견국가로서의 역량을 발휘하기 위해서는, 첫째, MDGs의 성공모델을 확산시키고, 둘 째, 전문성과 국제역량을 강화하며, 셋째, 경제규모와 외교역량에 걸맞은 원조국가로서의 책임을 수행하 며, 넷째, 한국의 개발경험을 기초로 한 차별화된 원조를 제공해야 할 것이다.
