At the point of building standardization, standardizations of design and materials have showing visible results. But standardization in building construction has been lagged. The purpose of this study is to propose standardization execution method in construction area in order to minimize waste of materials, to reduce construction period and to replace old material with standard material focusing on plaster board execution. Conventional construction method with standardization construction method were compared and analyzed in plaster board works which were executed at Ji-Haeng district in Doon Doo Chon.

문준호,송민규,황상훈 대한전자공학회 2006 電子工學會論文誌-SD (Semiconductor and devices) Vol.43 No.8

In this paper, CMOS analog-to-digital converter (ADC) with a 6-bit 100MSPS at 1.8V is described. The architecture of the proposed ADC is based on a folding type ADC using resistive interpolation technique for low power consumption. Further, the number of folding blocks (NFB) is decreased by half of them, compared to the conventional ones. A moebius-band averaging technique is adopted at the proposed ADC to improve performance. With the clock speed of 100MSPS, the ADC achieves an effective resolution bandwidth (ERBW) of 50MHz, while consuming only 4.5mW of power. The measured result of figure-of-merit (FoM) is 0.93pJ/convstep. The INL and DNL are within ±0.5 LSB, respectively. The active chip occupies an area of 0.28mm2 in 0.18um CMOS technology. 본 논문에서는, 1.8V 6-bit 100MSPS CMOS A/D 변환기를 제안한다. 제안하는 A/D 변환기는 저 전력소모를 위해 폴딩 구조의 A/D 변환기로 구현되었으며, 특히 전압구동 인터폴레이션 기법을 사용하여 전력소모를 최소화 하였다. 또한 전체 A/D 변환기의 전력소모 감소를 위해 새로운 폴더 감소회로를 제안하여 기존의 폴딩 A/D 변환기에 비해 폴더 및 프리앰프 수를 절반으로 줄였고, 새로운 프리앰프 평균화 기법을 제안하여 전체 A/D 변환기의 성능을 향상시켰다. 설계된 A/D 변환기는 100MSPS의 변환속도에서 50MHz의 ERBW를 가지며, 이때의 전력소모는 4.38mW로 나타난다. 또한 측정결과 FoM은 0.93pJ/convstep의 우수한 성능 지표를 갖으며, INL 및 DNL은 각각 ±0.5 LSB 이내의 측정결과를 보였다. 제안하는 A/D 변환기는 0.18um CMOS공정으로 제작되었고 유효 칩 면적은 0.28mm2 이다.

This research aims to investigate the determinants of Incheon international airport reuse intention. As explanatory variables, this research selects employee service, safety, food and beverage service, tourism accessibility. This study used survey as main instrument. For the data collection, this research employs online panel data service. The number of observation is 285 for the data analysis. This study implements frequency analysis, exploratory factor analysis, reliability test, correlation matrix, and multiple regression analysis for data collection. Considering the results, employee service is positively associated with reuse intention. Moreover, the results indicate that reuse intention is positively influenced by safety. The results also present that tourism accessibility is negatively related to the reuse intention of Incheon international airport. This study has practical implication by offering the information of airport customers.

Numerical Simulation of the Flat Die for Shape Optimization in the Single-screw Extrusion Process

문준호,김시조 한국고무학회 2022 엘라스토머 및 콤포지트 Vol.57 No.4

In this study, we chose a flat die to optimize a general die geometry. The optimization was aimed at obtaining a uniform velocity distribution across the exit of the die. For the optimization, the input and output design parameters were randomly computed, and response surfaces were generated to obtain statistical data for the minimum and maximum sensitivities computed during optimization. Subsequently, object functions with constraints were numerically computed to obtain the minimum errors in the velocity difference (i.e., variable “Outp” in this study). Finally, we obtained the candidate optimized dataset. Note that the current numerical computations were simultaneously conducted for an entire extruder, i.e., screw plus die. The numerical outlet velocity distributions in the modified die geometry tended to be much more uniform than the conventional distributions in the current optimization processes for this specific flat die.

문준호,김주현,문상호,김시조 한국유변학회 2017 Korea-Australia rheology journal Vol.29 No.1

It is of great importance to understand the stretching and folding mechanism in the multiflux co-extrusion die to get uniform multilayer distribution at the end of die lip in the multilayer co-extrusion processes. In this work, to understand the mechanism of the layer distribution, modeling and numerical simulation were carried out for three-dimensional flow analysis in the multilayer co-extrusion die. The multilayer flow fields were numerically visualized and analyzed on the arbitrary cross-section of the multiflux die. In addition, numerical results for the multiflux die characteristics were obtained for non-Newtonian fluids in terms of power-law index for the cross model, which will be useful for the optimal design of screw and die, simultaneously, in the multilayer co-extrusion process.

문준호,김동수 한국전자거래학회 2019 한국전자거래학회지 Vol.24 No.3

After the 4th industrial revolution, the healthcare industry is striving to find new business models through new technologies. Among them, blockchain technology is one of thetechnologies that have great interest in the healthcare industry. Most providers of personal health record systems have difficulty in securing marketability due to various problems. Therefore, they try to integrate blockchain technology to develop new systems and gain marketability. However, blockchain has limitations in solving the problems of the personalhealth record system. In this study, we have designed a personalized health data management framework that enables information subjects to acquire full ownership rights of individual’shealth data, based on distributed ledger technology. For the framework design, we refer to the structure of R3 Corda. It was designed with a different network structure than the existing blockchain systems so that the node can be operated on the personal user's mobile device. This allows information subjects to directly store and manage their own data and share data with authorized network members. Through the proposed system, the information utilization of the healthcare industry can be improved and the public health promotion and medical technology development can be realized. 4차 산업 혁명이 시작되고 헬스케어 분야 역시 신기술을 접목한 새로운 비즈니스 모델을 찾기 위해 노력하고 있다. 그중 블록체인 기술은 의료 분야에서 큰 관심을 갖는 기술 중 하나이다. 여러 가지 문제들로 인하여 시장성 확보에 어려움을 겪고 있는 개인 건강 기록 시스템 분야 역시 블록체인 기술의 접목을 통해 시스템의 발전과 시장성 확보를 위한 노력을 기울이고 있다. 하지만 블록체인은 개인 건강 기록 시스템의 문제를 해결하기에는 한계가 있다. 이에 본 연구에서는 블록체인의 상위 개념인 분산 원장 기술을 기반으로 정보 주체가 개인 건강 데이터에 대한 온전한 소유권을 확보할 수 있는 개인 주도적 건강 데이터 관리 프레임워크를 설계하였다. 프레임워크의 설계를 위해 컨소시엄 블록체인 중 하나인 R3 Corda의 구조를 참고하였으며, 개인 사용자의 모바일 장치에 노드를 운용할 수 있도록 기존 블록체인과 다른 네트워크 구조를 설계하였다. 이를 통해 정보주체가 직접 자신의 정보를 저장 및 관리하고 허가된 네트워크 구성원들에게 정보를 공유할 수 있도록 하였다. 제안된 시스템을 통해 의료 산업의 정보 활용도를 향상시키고 국민 건강 증진과 의료 기술의 발전을 이룰 수 있을 것이다.

문준호,Ji-Yei Choi,Jung-Taek Kang,Sol Ji Park,Su Jin Kim,장구,이병천 대한수의학회 2014 Journal of Veterinary Science Vol.15 No.1

The level of P4 at the time of embryo transfer (ET) isimportant. P4 concentrations and numbers of corpora lutea for126 recipients were evaluated. Nuclear transfer embryos weretransferred into 126 surrogates. 11 maintained their pregnancyuntil full-term delivery, 17 miscarried, and implantation failedin 98 animals. P4 levels in the full-term group were significantlydifferent from those of the pigs that aborted or in whichimplantation failed (p < 0.05). However, the numbers ofcorpora lutea were not significantly different. These findingsindicate that the concentration of progesterone can be animportant factor for successful ET in pigs.
