(연구배경 및 목적) 서울시는 경춘선 복선 전철화사업이 2010년에 마무리됨에 따라 기존 경춘선의 성북역에서 서울시 경계까지 약 6.3㎞ 폐선부지구간을 공원화하기로 하였다. 이 사업은 2013년부터 전체구간을 3단계로 나눠‘경춘선숲길공원 조성사업’으로 명명되어 공사가 진행되었다. 2017년 하반기부터 진행된 3단계 사업에서는 성북역과 육사삼거리에서 구리시 경계까지의 철도 및 주변공간을 공원화하기로 하고 화랑대역사(驛舍)를 전시관으로 변경하도록 계획하였다. 본 디자인제안에서는 화랑대역을 활용하여 역사적 가치를 보존하며 경춘선이 지닌 의미를 방문객과 공유할 수 있는 전시관을 계획하였다. (연구방법) 디자인의 범위는 크게 건축 공간부분과 내부전시계획부분으로 나뉜다. 건축 공간에서는 기존의 역사(驛舍)를 전시공간으로 사용할 수 있도록 부분적으로 개보수하고 마감재를 변경하였다. 전시계획 부분에서는 현황 및 사례분석, 전시개념설정, 전시 시나리오, 공간연출과 세부적인 전시물 제작설치 방법을 제안하였다. (결과) 현황 및 사례 분석을 통해 전시기본방향을 첫째, 실물전시 중심의 연출과 원형의 보존 둘째, 공감각적 연출을 통한 역의 과거 모습 표현 셋째, 사람들의 이야기와 기억의 표현으로 설정하였다. 이러한 기본방향을 전제로 전시개념을‘간이역, 시간의 향기로 물들다’로 설정하고 화랑대역의 역사, 화랑대역의 기억과 화랑대역과 사람들의 이야기로 공간 시나리오를 전개하였다. 건축 리모델링 계획은 크게 세 가지 방향에서 접근하였다. 첫째, 색채, 마감재 및 공간의 부분요소가 전체적인 조화를 이루도록 하였다. 둘째, 여행의 흥겨운 감정이 그대로 유지될 수 있도록 공간을 연출하였다. 셋째, 비대칭 삼각형 지붕구조의 조형성을 그대로 살릴 수 있도록 하였다. 구체적인 전시계획으로서 첫 번째 존인‘화랑대역, 우리의 역사와 함께하다’는 화랑대역사관에서 가장 큰 공간인 대합실을 활용하여 관람객이 역과 관련된 문학과 음악자료를 읽고 들어봄으로써 그 당시 이 역을 이용했던 사람들의 느낌과 감정을 이해 할 수 있도록 하였다. 두 번째 존‘화랑대역, 우리의 기억을 담다’는 화랑대역의 공간과 관련된 이야기를 주제로 하며 등록문화재로 지정된 화랑대역의 건축적 특징과 현재의 모습이 유지되기까지의 복원과정을 모형으로 설명하였다. 세 번째 존‘화랑대역, 수 많은 사람들의 이야기를 담다’에서는 공간 중앙에 역의 플랫폼과 승강장을 재현하여 분주한 모습을 생동감 있게 표현하였다. (결론) 본 디자인제안에서는 ‘경춘선숲길공원 조성사업’의 마무리 과정으로서 기존 화랑대역을 활용하여 화랑대역사관으로 변화시켰으며 건축물의 개보수와 전시콘텐츠개발 부분으로 나누어 접근하였다. 향후, 지속적 관람객 유입을 위해서는 전시관 내부와 경춘선숲길공원의 외부시설물을 연계하여 체험할 수 있는 행사가 지속적으로 개발되어야 한다. 또한 화랑대역사관 주변공원을 체험형 테마파크로 변화시키고 어린이를 대상으로 한 다양한 프로그램이 제공되어야 한다. (Background and Purpose) In 2010, the double electric track of Kyungchun railroad was finished. Seoul municipal authority decided to develop a park that the area from Seongbuk Station to border of Seoul. This project was proceeded by three stages and named as ‘Developing project of Kyungchun railroad forest park’from 2013 to 2017. In 2017, the third stage of project included that not only making park the nearby rail road from Seongbuk Station to a crossing with the three corners of Korea Military Academy, but changing Hwarangdae Station to a historical museum. This study proposed a plan for preserving historical value of the station and sharing the significance of Kyungchun railroad with visitors. (Method) The overall design project was divided by two parts; planning architectural space and exhibition contents. For planning architectural space, exiting station space was partially renovated and applied finishing materials to change the space as a museum. For planning exhibition contents, Analysing existing circumstances, establishing concept, exhibition scenario, producing space, and plan for fabricating media were proposed for the historic museum. (Results) By analyzing circumstances and example works, the directions of project was established by which are to preserve the archetype by displaying real objects, to produce the past station features by synesthetic presentation and to describe stories and memories of people. This study proposed not only the exhibition concept ‘Station, saturated by scent of time’ as the design directions, but spatial scenario with history, memories, and people of Hwarangdae Station. There were three ways to renovate the exiting architecture of the station. Most of all, color, material, and spatial factors are well matched with overal architectural structure. The second, exhibition space is well produced to make visitors being felt the hilarious atmosphere. The last, asymmetric roof structure is maintained to presenting unique configuration. The exhibition planning details are compromised as three parts. Renovated waiting lounge, first exhibition zone ‘Hwarangdae Station is holding our history’is the largest space. Visitors are able to understand the feeling and emotion of passengers through watching literary and musical items. The next zone ‘Hwarangdae Station has our memories’focused on architectural space that is made by a scale model and registered as a cultural property. The last zone ‘Hwarangdae Station shows stories of passengers’ described vivid and packed scenary of platforms in the center of the museum. (Conclusions) This study approached design in two parts which are architectural reconstruction and exhibition scenario to change the exiting station as a historical museum. To attract visitors constantly, experiencing events relevant to external facilities are being developed. In addition, the surrounding park of historical museum is needed to change as a theme park and to provide various hands-on program for children.

This paper focuses on the fastener test of ultrasonic method applying TAY(Torque and Angle to Yield) specifications for Chassis’s critical joints. By contrast with the existing sensors for measuring tension-compression, Ultrasonic testing method is nondestructive test that is unnecessary to make test sample machined. Due to not machined test samples, the yield strength and prooflaod of bolts doesn’t become weaken. We can measure bolt preload for clevis-type joint by applying the ultrasonic testing method. Therefore, considering the advantages of ultrasonic testing method, it is highly recommended to use this test method for measuring tension data of clevis-type joint. Especially When determining ‘TAY(Torque and angle to yield) specification’ for the clevis-type joints, the ultrasonic method is highly appropriate for measuring the tension of jointed bolts without destroying the unique proof-load/yield strength.

The design improvement of mechanical ventilation systems (which usually operate 24/7 year round) for underground parking lots is critical for human health and energy. In this paper, a mechanical ventilation system was re-designed and improved to solve the problems of ventilation performance and high fan energy use in a large underground parking lots. The inlets/outlets are at the ground level of the building, and the dilution method is used to calculate the required exhaust and supply ventilation rates. Two types of fan room for vent tower models (with sirocco fan and airfoil fan) were constructed and simulated under seven design procedures using computational fluid dynamics (CFD). For the mechanical ventilation of an underground parking lot with an airfoil fan, the ranges of the computed air flow rate and ventilation efficiency are consistent with the requirements of ventilation performance and design criteria. This system optimization procedure of the ventilation system that has been re-designed is effective in meeting the required air flow rate in underground parking lots.

Effects of Chain Orientation and Packing on the Photoluminescence and Photothermal Properties of Polybenzimidazole Fibers with Meta-Linkage

Park, Jinho,Jeong, Young Gyu American Chemical Society 2015 Macromolecules Vol.48 No.24

<P>We herein report the influences of chain orientation and packing on the photoluminescent (PL) and photothermal properties of polybenzimidazole fibers with meta-linkage under different excitation wavelengths (λ<SUB>ex</SUB>) and powers of laser sources. For the purpose, poly[2,2′-(<I>m</I>-phenylene)-5,5′-bibenzimidazole] (PmBI) was synthesized and then processed into fibers via solution spinning and heat treatment. The chain orientation and packing of the as-spun PmBI fiber decreased and increased owing to the heat treatment, respectively, which resulted from the nonlinear chain conformation of PmBI with meta-linkage. It was found that the visible PL intensity under λ<SUB>ex</SUB> = 325 nm, which is associated with an efficient interchain photorelaxation between benzimidazole rings, was much higher for the as-spun fiber with higher chain orientation, while the infrared PL intensity under λ<SUB>ex</SUB> = 514 nm, which is dominated by an intrachain photorelaxation, was far higher for the heat-treated fiber with higher chain packing. Accordingly, the heat-treated PmBI fiber exhibited excellent photothermal heating behavior by attaining maximum temperature increments (Δ<I>T</I><SUB>max</SUB>) of ∼31.7 °C under λ<SUB>ex</SUB> = 405 nm and 18.4 mW, which was even higher than the as-spun fibers (Δ<I>T</I><SUB>max</SUB> ∼ 27.5 °C). For the PmBI fibers, the Δ<I>T</I><SUB>max</SUB> values were also found to increase with the decrease of λ<SUB>ex</SUB>.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/mamobx/2015/mamobx.2015.48.issue-24/acs.macromol.5b02266/production/images/medium/ma-2015-02266y_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/ma5b02266'>ACS Electronic Supporting Info</A></P>

Dielectric function of Si_1−xGe_x films grown on silicon-on-insulator substrates

Park, In-Sung,Chan Jung, Yong,Ahn, Jinho,Shim, Tae-Hun,Lee, Du-Yeong,Park, Jea-Gun American Institute of Physics 2014 Journal of Applied Physics Vol.115 No.23

The dielectric functions of undoped and P-doped Si1-xGex (SiGe) films with a compressive strain on silicon-on-insulator (SOI) substrates are obtained by using spectroscopic ellipsometry. The respective Kato-Adachi and Tauc-Lorentz models are best fitted to the undoped and P-doped SiGe films to obtain their complex dielectric functions. The undoped SiGe films are characterized by multimodal peaks in the dielectric function, whereas the P-doped SiGe films exhibit only a broad peak. Further, the E-0 and E-1 critical points (CPs) of the undoped SiGe films are strongly dependent on the Ge concentration, whereas the E-2 CPs are independent of concentration. The E-0 and E-2 CPs in the undoped SiGe films on an SOI substrate are lower than those of SiGe on a bulk-Si substrate owing to the higher strain. For P doping in SiGe, its dose causes non-monotonic variations in E-g and E-0. (C) 2014 AIP Publishing LLC.

These days, bacterial detection methods have some limitations in sensitivity, specificity, and multiple detection. To overcome these, novel detection and identification method is necessary to be developed. Recently, NGS panel method has been suggested to screen, detect, and even identify specific foodborne pathogens in one reaction. In this study, new NGS panel primer sets were developed to target 13 specific virulence factor genes from five types of pathogenic Escherichia coli, Listeria monocytogenes, and Salmonella enterica serovar Typhimurium, respectively. Evaluation of the primer sets using singleplex PCR, crosscheck PCR and multiplex PCR revealed high specificity and selectivity without interference of primers or genomic DNAs. Subsequent NGS panel analysis with six artificially contaminated food samples using those primer sets showed that all target genes were multi-detected in one reaction at 108 -105 CFU of target strains. However, a few false-positive results were shown at 106 -105 CFU. To validate this NGS panel analysis, three sets of qPCR analyses were independently performed with the same contaminated food samples, showing the similar specificity and selectivity for detection and identification. While this NGS panel still has some issues for detection and identification of specific foodborne pathogens, it has much more advantages, especially multiple detection and identification in one reaction, and it could be improved by further optimized NGS panel primer sets and even by application of a new real-time NGS sequencing technology. Therefore, this study suggests the efficiency and usability of NGS panel for rapid determination of origin strain in various foodborne outbreaks in one reaction.

The novel anti-adipogenic effect and mechanisms of action of SGI-1776, a Pim-specific inhibitor, in 3T3-L1 adipocytes

PARK, YU-KYOUNG,HONG, VICTOR SUKBONG,LEE, TAE-YOON,LEE, JINHO,CHOI, JONG-SOON,PARK, DONG-SOON,PARK, GI-YOUNG,JANG, BYEONG-CHURL UNKNOWN 2016 INTERNATIONAL JOURNAL OF MOLECULAR MEDICINE Vol.37 No.1

<P>The proviral integration site for moloney murine leukemia virus (Pim) kinases, consisting of Pim-1, Pim-2 and Pim-3, belongs to a family of serine/threonine kinases that are involved in controlling cell growth and differentiation. Pim kinases are emerging as important mediators of adipocyte differentiation. SGI-1776,an inhibitor of Pim kinases, is widely used to assess the physiological roles of Pim kinases, particularly cell functions. In the present study, we examined the effects of SGI-1776 on adipogenesis. The anti-adipogenic effect of SGI-1776 was measured by Oil Red O staining and AdipoRed assays. The effect of SGI-1776 on the growth of 3T3-L1 adipocytes was determined by cell count analysis. The effects of SGI-1776 on the protein and mRNA expression of adipogenesisrelated proteins and adipokines in 3T3-L1 adipocytes were also evaluated by western blot analysis and RT-PCR, respectively. Notably, SGI-1776 markedly inhibited lipid accumulation during the differentiation of 3T3-L1 preadipocytes into adipocytes. On a mechanistic level, SGI-1776 inhibited not only the expression of CCAAT/enhancer-binding protein-alpha (C/EBP-alpha), peroxisome proliferator-activated receptor-gamma (PPAR-gamma) and fatty acid synthase (FAS), but also the phosphorylation of signal transducer and activator of transcription-3 (STAT-3). Moreover, SGI-1776 decreased the expression of adipokines, including the expression of leptin and regulated on activation, normal T cell expressed and secreted (RANTES) during adipocyte differentiation. These findings demonstrate that SGI-1776 inhibits adipogenesis by downregulating the expression and/or phosphorylation levels of C/EBP-alpha, PPAR-gamma, FAS and STAT-3.</P>
