In conventional method of supporting soil shuttering wall during excavation a system of struts and wales to provide cross-lot bracing is common in trench excavations and other excavations of limited width. This method, however, becomes difficult and costly to be adopted for large excavations since heavily braced structural systems are required. Another expensive and unsafe situations are expected when temporary struts must be removed for the construction of underground structures. This paper introduces innovative strut systems which can be used as permanent underground structures after its role as brace system to resist earth pressure during excavation phase. Underground structural system suggested from architect is checked against the soil lated pressures before the analysis of stresses developed from gravity loads. In this technology, named SPS(Struts as Permanent System), retaining wall is installed first and excavation proceeds until the first level of bracing is reached. Braces used as struts during excavation will serve as permanent girders when buildings are in operation. Simultaneous construction of underground and superstructure can proceeds when excavation ends with the last level of braces being installed. In this paper, construction sequence and the calculation concept are explained in detail with some photo illustrations. SPS technology was applied to three selected buildings. One of them was completed and two others are being constructed Many sensors were installed to monitor the behavior of retaining wall, braces as column in terms of stress change and displacement. Adjacent ground movement was also obtained. These projects demonstrate that SPS technology contributes to the speed as well as the economy involved in construction.

Purpose - The spread of COVID-19 is increasing interest in un-tact consumption and sustainable consumption. This trend can be shown in the SNS marketing activities of the beauty industry. In particular, it appears that consumers who are interested in organic cosmetics communicate a lot through SNS, so an SNS marketing strategy will be an important means not only for organic cosmetics companies but also for companies that want to launch a new organic cosmetic brand. This research aims to study the influence of organic cosmetic’s SNS marketing characteristics on Consumer Credibility and Purchasing Intention. Cosmetic companies need to strategically operate SNS marketing by referring to the results of this research. Design/Methodology/Approach - In this research, the questionnaire was filled out through Google Survey, and the questionnaire was sent through SNS from May 6, 2021, to May 21, 2021. As a result, a total of 210 survey responses were collected. All of the items used in this research were measured on a 5-point Likert scale and responded from none (=1) to very yes (=5). Descriptive statics, frequency analysis, reliability analysis, and regression analysis were performed using SPSS 24 to confirm the research hypothesis and analyze demographic characteristics. Findings - Among the Marketing Characteristics of SNS, Information Sharing on YouTube and Instagram is a factor that affects Consumer Credibility. And the Enjoyment on YouTube, Instagram and Kakao has an effect on Consumer Credibility and Purchasing Intention. Research Implications - Among the Marketing Characteristics of SNS, Enjoyment was confirmed to be an important factor influencing Consumer Credibility and Purchasing Intention. So it can be seen that cosmetic companies should continuously provide beauty contents with fun and enjoyment about organic cosmetics to consumers.

Rain-sensing windshield wipers, which can automatically activate automotive wipers in case of rain, operate based on an optical sensor. In line with the recent advancement of autonomous driving, the development of vision-based rain sensors has also been actively performed due to their increasing demand. This paper presents a computer vision-based real-time rain-sensing wiper system. A software algorithm to compute the presence and intensity of rainwater was developed, and a hardware prototype was constructed. It was confirmed that the area covered with rainwater on the windshield could be quantified in real-time, and the wipers could be automatically operated when the area exceeds a preset critical value.

체외막산소화장치를 사용하는 경우 항응고제의 사용은 필수적이며, 그 동안 헤파린이 널리 사용되어 왔다. 하지만 헤파린은 출혈 위험성을 증가시키며, 이로 인해 중대한 합병증이 발생할 수 있다. 이 증례에서 저자들은 심인성 쇼크를 동반한 급성 심근경색증 환자에서 체외막산소화장치의 항응고제로 nafamostate mesilate를 사용하였다. 항응고제로 nafamostat mesilate만 사용한 기간에는 nafamostat mesilate를 평균 2.64±1.11 mg/kg/hr의 속도로 투여하여 ACT를 평균 128.68±21.25초로 유지하였고, 헤파린을 함께 사용한 기간에는 nafamostat mesilate를 1.17±0.34 mg/kg/hr, 헤파린을 3.83f±1.0 Unit/kg/hr의 속도로 투여하여 ACT는 평균 140.2±14.47초로 유지하였다. 기존의 헤파린을 항응고제로 사용한 환자들과 비교하였을 때, 사용된 oxygenator 갯수와 수혈량이 모두 적었다. 저자들은 체외막산소화장치의 항응고제로 nafamostate mesilate를 사용하여 출혈에 의한 합병증이나 oxygenator의 교환없이 성공적으로 치료된 예를 경험하여 이를 보고한다. It is essential during extracorporeal membrane oxygenation (ECMO) to extend the activated clotting time (ACT) using anticoagulants to prevent blood clot formation. Traditionally, heparin has been used as an anticoagulant during ECMO. Hemorrhaging due to systemic heparinization is considered a major complication of ECMO. A 48-year-old man was admitted due to cardiogenic shock with acute myocardial infarction. ECMO was instituted because of recurrent ventricular tachycardia and refractory shock. We used nafamostat mesilate (Futhan) as an anticoagulant to reduce hemorrhagic complications. The total bypass time was 153 h. The average dose of nafamostat mesilate was 2.64±1.11 mg/kg/h; the average ACT was 128.68±21.24 seconds. Only a few units were transfused, and there was no oxygenator failure or hemorrhagic complications. Thus, nafamostat mesilate may reduce the need for transfusions and hemorrhagic complications during ECMO. (Korean J Med 79:181-186, 2010)

저전력 연산능력과 무선통신 기능을 포함한 경량의 센서노드들로 구성된 무선 센서네트워크는 자연 환경의 모니터링에서 군사적인 목적에 이르기까지 다양한 어플리케이션을 창출 할 수 있다. 그러나, 다수의 저가 무선 노드를 배치해야 하는 센서네트워크의 특성상 안정성이 높은 고가의 부품을 사용할 수 없어, 이에 대한 보완 방안에 대한 연구가 활발히 진행 중이다. 특히, 무선 노드들 간의 시간동기화는 가용 무선 대역폭이 적은 무선 센서네트워크에서 TDMA 스케줄링등의 기술을 구현하기 위한 필수적인 기반기술로서 네트워크 특성을 고려한 새로운 동기화 기법을 요구하고 있다. 본 논문에서는, 무선센서노드의 특성을 파악하고 시간 동기화 수행 시 발생할 수 있는 오차요인을 분석하여, 넓은 지역에 산발적으로 분포되는 무선 센서네트워크의 특성을 보완할 수 있는 새로운 시간동기화 기법을 제안한다.

무선 센서노드를 활용한 다양한 네트워크 설계 기술은 실생활의 각종 정보 수집에서부터 환경 모니터링까지 폭넓은 활용범위를 바탕으로 저전력 노드 설계 기술, 노드간 라우팅 프로토콜, 초소형 운영체제 및 미들웨어기술 등 관련 연구가 활발히 수행되고 있으며, 실내 센서네트워크에 분포된 노드의 절대위치를 측정하는 위치인식 시스템은 노드의 이동성, 다수성 그리고 환경의 제약성으로 인해 이를 보완할 시스템이 요구되고 있다. 이에 본 논문에서는 고정 센서노드의 배치밀도에 따라 위치정보를 선별적으로 처리하는 위치데이터 처리기와 다중 위치데이터의 발생을 원천적으로 차단하는 노드간 라우팅 기법을 통해, 센서노드의 이동성과 다중성을 효과적으로 보완하는 실내 이동객체 위치인식 시스템을 설계하고 서비스 구현을 위한 센서네트워크 플랫폼을 제안한다.

Objective: The purposes of this study were to investigate the types and the incidences of chromosomal abnormalities, and to provide an explanation for the genetic causations of recurrent spontaneous abortions in Korean population. Methods: Cytogenetic studies were carried out in 535 couples with at least two spontaneous first trimester abortions from January 1981 to December 2003. For karyotype analysis, we used modified Moorhead method by Giemsa staining and Giemsa-Trypsin-Giemsa banding Results: The overall incidence of chromosome abnormality was 32 out of 535 cases (5.98%). There were 25 cases (4.67%) of translocation and 7 cases (1.31%) of inversion. In translocation, 5 cases (0.93%) of Robertsonian translocation and 20 cases (3.74%) of reciprocal translocation were observed. In inversion, 6 cases (1.12%) of inversion of chromosome 9 and one case (0.19%) of inversion of chromosome 18 were found. Conclusion: In this study, overall chromosomal abnormality rate in couples with recurrent spontaneous abortions is much higher than that in the general population. So, chromosomal analysis should be offered for the prognostic information in genetic counseling such as prenatal diagnosis in couples with repetitive reproductive failure.
