It is important to define a standard method to store basic sensor information, such as the type and the structure for an piezoelectric actuator and there is no such method defined in the IEEE 1451.4 transducer electronic data sheet (TEDS) so far. The major challenge is to choose a suitable standard template that can be used with actuators for piezoelectric devices. In this paper, we propose a new template TEDS and the structure of interface for IEEE 1451.4 for piezoelectric actuators.

Well defined 1-dimentional (1-D) photonic crystals of polystyrene replicas have been successfully obtained by removing the porous silicon from the free-standing rugate porous silicon/phenylmethylpolysiloxane composite film. Rugate porous silicon was prepared by an electrochemical etching of silicon wafer in HF/ethanol mixture solution. Exfoliated rugate porous silicon was obtained by an electropolishing condition. A composite of rugate porous silicon/phenylmethylpolysiloxane composite film was prepared by casting a toluene solution of phenylmethylpolysiloxane onto the top of rugate porous silicon film. After the removal of the template by chemical dissolution, the phenylmethylpolysiloxane castings replicate the photonic features and the nanostructure of the master. The photonic phenylmethylpolysiloxane replicas are robust and flexible in ambient condition and exhibit an excellent reflectivity in their reflective spectra. The photonic band gaps of replicas are narrower than that of typical semiconductor quantum dots.

Chemerin receptor, which predominantly expressed in immune cells as well as adipose tissue, was found to stimulate chemotaxis of dendritic cells and macrophages to the site of inflammation. Chemerin is a widely distributed multifunctional secreted protein implicated in immune cell migration, adipogenesis, osteoblastogenesis, angiogenesis, myogenesis, and glucose homeostasis. Recent studies suggest chemerin may play an important role in the pathogenesis of obesity and insulin resistance and it becomes a potential therapeutic target for treating type II diabetes. The crystal structure of chemerin receptor has not yet been resolved. Therefore, in the present study, homology modelling of CMKLR1 was done utilizing the crystal structure of human angiotension receptor in complex with inverse agonist olmesartan as the template. Since the template has low sequence identity, we have incorporated both threading and comparative modelling approach to generate the three dimensional structure. 3D models were generated and validated. The reported models can be used to characterize the critical amino acid residues in the binding site of CMKLR1.

Urotensin-2 receptor (UTS2R) is the most potent vasoconstrictor and plays a major role in the pathophysiology of various cardiovascular diseases and becomes a potential target for human pharmacotherapy. The crystal structure of Urotension-2 receptor has not yet been resolved. Hence, in the current study homology modelling of UTS2R was done utilizing the crystal structure of human delta opioid receptor as the template. Since the template has low sequence identity, we have incorporated both comparative modelling and threading approach to generate the three dimensional structure. 10 models were generated and validated. The reported models can be used to characterize the critical amino acid residues in the binding site of UTS2R.

Some open tubular (OT) molecule imprinted polymer (MIP) silica capillary columns with templates of camphor derivatives such as 10-camphorsulfonic acid (10-CSA), 10-camphorsulfonamide (10-CS) and camphor-p-tosyl hydrazone (CTH) have been successfully prepared by the prior generalized preparation protocol. The three MIP thin layers of different templates showed quite different morphologies. The chiral selectivity of each MIP column for the template enantiomers was optimized by changing eluent composition and pH. The optimization conditions were found to be different for the three MIPs. This work suggests prospective successful extension of the generalized preparation protocol for OT-MIP silica capillary columns toward templates of a variety of chemical groups.

현재 국내 건설사에서 일부 BIM을 적용하고 있지만, BIM도입에 따른 업무변화와 새로운 학습에 대한 막연한 거부감으로 업무에 적극적으로 활용되지 못하고 있다. 또한 설계단계에 작성된 BIM모델을 시공단계에 활용하기 위해서는 시공시 필요한 공정정보가 제공되어져야 하는데, 공정정보의 입력 체계와 활용 방법이 미비한 실정이다. 따라서 건설사의 BIM의 적극적 도입과 생산성 향상을 위해 본 연구는 BIM의 기본적인 정보를 건축 공정상의 흐름에 따라 필요한 정보가 쉽고 간편한 결과로 나타날 수 있도록 건설공정관리 BIM템플릿을 개발하였다. 이를 위해 작업분류체계(WBS)의 단위정보(주요단위, 세부단위, 상세단위)를 매개변수에 적용하여 공정별 기간별 공정진도 탐색기를 구성하고, 3D뷰 일람표를 생성하였다. 템플릿을 사용하기 위해 Dynamo를 활용하여 BIM모델 객체에 공정정보를 입력하는 방법을 고안하였다. 또한 건설공사의 자재별 물량을 쉽고 빠르게 산출 할 수 있도록 하였다. 건설공정관리 BIM템플릿을 검증하기 위해 실제 프로젝트에 적용하여 가시성과 일람표를 평가하였다. 그 결과 건설공정관리 BIM템플릿이 프로젝트 공정정보를 용이하게 관리할 수 있게 하여, 건설사의 BIM의 적극적 도입과 생산성 향상에 기여할 수 있다.

$Al_2O_3$ has received wide attention with established use as a catalyst and growing application in structural or functional ceramic materials. On the other hand, the boehmite (AlO(OH)) obtained by sol-gel process has exhibited a decrease in surface area during phase transformation due to a decline in surface active site at high temperature. In this work, $Al_2O_3$-CuO/ZnO (ACZ) and $Al_2O_3$-CuO/CeO (ACC) composite materials were synthesized with aluminum isopropoxide, copper (II) nitrate hemi (pentahydrate), and cerium (III) nitrate hexahydrate or zinc (II) nitrate hexahydrate. Moreover, the Span 80 as the template block copolymer was added to the ACZ/ACC composition to make nano size particles and to keep increasing the surface area. The ACZ/ACC synthesized powders were characterized by Thermogravimetry-Differential Thermal analysis (TG/DTA), X-ray Diffractometer (XRD), Field-Emmision Scanning Electron Microscope (FE-SEM), Bruner-Emmett-Teller (BET) surface analysis and thermal electrical conductivity (ZEM-2:M8/L). An enhancement of surface area with the addition to Span 80 surfactant was observed in the ACZ powders from 105 $m^2$/g to 142 $m^2$/g, and the ACC powders from 103 $m^2$/g to 140 $m^2$/g, respectively.

The design of DNA nanostructures is of fundamental importance, the intrinsic value of DNA as a building-block material lies in its ability to organize other bio-molecules with nanometer-scale spacing. Here, we report the fabrication of DNA scaffolds with nano-pores (<10 nm size) that formed easily without the use of additives (i.e., avidin, biotin, polyamine, or inorganic materials) into large-scale structures by assembling DNA molecules at near room temperature ($30^{\circ}C$) and low pH (~5.5). Protein immobilization results also confirmed that a fibronectin (FN) proteins/large scale DNA scaffolds/aminopropylytriethoxysilane (APS)/SiO2/Si substrate with high sensitivity formed in a well-defined manner. The DNA scaffolds can be applied for use with DNA-based biochips, biophysics, and cell biology.

본 논문에서는 차량 헤드라이트의 불량 유무를 판별하기 위하여 생산된 헤드라이트 이미지를 위치 및 회전 보정 후 검사이미지의 ROI(Region of Interest)와 표준 이미지의 ROI와의 유사도를 이용하여 불량 유무를 판단하는 방법을 제안하였다. 유사도 판별은 OpenCV에서 제공하는 템플릿매칭 유사도 판별방법을 응용하여 히스토그램 기반에서 유사도를 판별하는 방법을 사용하였고, 성능 분석을 목적으로 기존 OpenCV의 기본 방법과 비교하였다. 분석결과, OpenCV의 기본 방법보다 좋은 성능을 보임을 알 수 있었고, 제안 방법의 경우 불량 판별율 100%에 근접함을 알 수 있었다.
