Bracket supported R/C Downward (BRD) method is an advanced construction method which is free from using supports, short pillars propping up a veranda floor. It allows placing concrete downward by gradually descending slab forms which are united with gird and beam forms. BRD method descents the slab forms which are suspended by threads using brackets and bracket attachment apparatuses. It maximizes the cost saving and the reuses of equipments relative to BRD form by reusing them as many as the numbers of the basement stories. This paper presents a simulation model that facilitates to model and analyze the productivity of BRD operation. By conducting motion and time study, resource processes of the operation and their tasks of the processes are defined. These atomic tasks are used as a building block to implement a simulation model that reflects the real world BRD operation on the job site. The model contributes to improve productivity of the operation by identifying the optimal resource combination and the productivity delay factors in BRD operation. A case study is implemented to verify the usability and validity of the system in practice.

Current environment in civil and construction industry has changed to actively adopt construction management (CM) in various areas. While it is found that exemplary CM projects have been carried out in many civil engineering sectors, concrete system framework has not been suggested due to ambiguous boundary between CM and supervision system, unclear perception of CM's role, and inexperienced organization and regime. This paper investigated the challenges faced in civil and construction industry, and analyzed the strategy that could improve the current immature CM system by conducting questionnaire survey from experts in various construction sectors. The results could provide valuable information that can involve diverse opinions and view points in project participants. 국내 사회간접자본(SOC) 프로젝트에서는 품질, 비용, 안전, 공정의 체계적이고 효과적인 관리를 위해 CM제도를 다양한 시범사업 및 실제 사업에 도입하고 있다. 그러나 국내 SOC사업에 CM제도를 도입하는 데는 여러 가지 실무적 장벽들이 존재한다. 내적으로는 안전문제 및 부실시공으로 인해 발생된 건설 산업에 대한 부정적인 시각을 극복하고, 외적으로는 건전한 시장개방과 국제화 및 세계화 시대에 부합하여 기술발전 및 개발을 통해 대외 경쟁력을 향상시켜야하는 과제를 안고 있다. 이를 달성하기위해 각 프로젝트 참여자들이 효율적으로 융화 될 수 있는 있는 토대를 제공하는 CM제도의 정착은 중요한 현안이다. 그러나 현재 발주처의 입장에서 국내 SOC 프로젝트 CM 제도의 정착화 방안을 객관적으로 규명하는 연구가 결여되어있다. 따라서 본 연구는 이를 규명하기 위해 국내 CM 프로젝트에 참여하는 구성원들(예, 발주처, 감리, 설계사, 시공사 등)을 대상으로 전문가 설문조사를 실시하여 CM도입에 대한 인식을 분석하고, 각 프로젝트 참여자들의 CM에 대한 입장을 정립하며, CM 정착을 위해 수반되는 문제점을 규명하고 이에 대한 대응 방안을 제시한다. 국내 SOC 프로젝트 CM에 대한 각 프로젝트 참여자들의 입장을 객관적으로 분석함으로써 CM 제도를 보다 효율적으로 정립하는데 기여한다.

Objective : The water extract of Yukgunja-tang(YGJT) has been traditionally used in treatment of qi deficiency and phlegm in Oriental medicine. However, little is known about the mechanism by which YGJT protects neuronal cells from injury damages. Therefore, this study was designed to evaluate the protective effects of YGJT on C6 glial cells by glutamate-induced cell death. Methods : The present study describes glutamate, which is known as an excitatory neurotransmitter, related with oxidative damages, and YGJT, which shows protective effects against glutamate-induced C6 glial cell death. One of the main mediators of glutamate-induced cytotoxicity was known on the generation of reactive oxygen species(ROS) via activation of NADPH oxidase (NOX). The protective effects of antioxidant(NAC) and NOX inhibitor(apocynin) on the glutamate-induced C6 glial cells were determined by a MTT reduction assay. Result : YGJT inhibited glutamate-induced ROS generation via inhibition of NOX expression on glutamate-stimulated C6 glial cells. Furthermore, YGJT attenuated glutamate-induced caspase activation. These results suggest that YGJT could be a new potential candidate against glutamate-induced oxidative stress and cell death. Conclusion : These findings indicate that in C6 glial cells, ROS plays an important role of glutamate-induced cell death and that YGJT may prevent cell death from glutamate-induced cell death by inhibiting the ROS generation.

Purpose : The purpose of study is activation of lumbar multifidus muscle by needle EMG during shoulder flexion in chronic low back pain patients. The subject were consisted of 10 women patients with chronic low back pain and healthy asymtomatic subject 10 women. Methods : 10 women patients with chronic low back pain and healthy asymptomatic subject 10 women is voluntary participated for the research. Subjects were positioned in standing. The needle EMG were measured activation of multifidus. Needle electrode was used to 28 gauge. The shoulder flexion movement used to activate the multifidus was then measured. Results : Results of the analysis showed that asymptomatic subjects had significantly larger multifidus muscle activation compared with CLBP subjects during shoulder flexion. Conclusion : This study will be used as multifidus measurement method of patient with chronic LBP. The multifidus muscle in chronic LBP patient clinical significance. Most of chronic LBP patients have multifidus contraction pattern. Therefore chronic LBP patients necessary multifidus activation measurement with needle EMG.

At present, available positioning satellites are not only the GPS, but also GLONASS, GALILEO, QZSS, BeiDou. However, the differential GPS, the augmentation service for increase the positioning accuracy, is follow the RTCM version 2.3 standard. So, it can service the correction information about only GPS. For solve this problem, RTCM is making the new version of RTCM message standard that can service the correction information for all of available GNSS. In South Korea, the software DGNSS RSIM system was installed at almost the whole DGNSS reference station. In this reason, that can cope with the new RTCM version 2.4 quickly. However, the DGNSS Reference Station based RSIM 1.3 can not make the GNSS's PRC simultaneously and can not support RTCM version 2.4. Thus, in this paper, the version of RTCM 2.4 is analyzed and the RTCM version 2.4 message generating module's architecture for software DGNSS reference station is designed. 현재 사용가능한 측위위성은 GPS외에도 GLONASS, GALILEO, BeiDou, QZSS등으로 다양해 졌다. 그러나 측위 정확도를 높이는 보강 서비스인 Differential GPS는 RTCM 버전 2.3 표준을 따르고 있어 GPS에 대한 보정정보만을 서비스할 수 있다. 이에 RTCM에서는 모든 위성에 대한 보정정보를 사용자에게 서비스할 수 있도록 RTCM 버전 2.4표준을 제정하고 있다. 한국의 DGNSS 기준국은 소프트웨어로 제작된 시스템이 설치되어 있어 새로운 표준에 빠르게 대응할 수 있다. 그러나 현재의 RSIM 1.3기반 DGNSS 기준국시스템의 아키텍처는 동시에 여러 GNSS의 보정정보를 생성하지 못하고, RTCM 2.4 역시 지원하지 못한다. 따라서 본 논문에서는 RTCM 버전 2.4 표준을 분석하고 소프트웨어 DGNSS 기준국 시스템이 RTCM 버전 2.4 표준에 맞춰 동시에 여러개의 GNSS에 대한 RTCM 보정정보 메시지를 생성할 수 있도록 하는 아키텍처를 설계하였다.
