Small - Scale Model 을 이용한 보강토 옹벽(擁壁)의 거동 해석
최영근,최기봉,신방웅 충북대학교 건설기술연구소 1990 建設技術論文集 Vol.9 No.1
This thesis was carried out experimental research a mechanical characteristics of the reinforced earth retaining wall using the small-scale model design and construction method through an experimental research about the reinforced earth retaining wall in the laboratory. It was investigated about problems occuring the application of the existing design theory in the design of the reinforced earth retaining wall. The Reinforcing strips were made of the aluminium foil strip instead of the geosynthetics and placed at 10 and 15㎝ in the horizental and vertical directions, respectively, and tensile strain was measured by the strain gages of the each strip, and the lateral movement of the skin element was observed and traced the failure phenomena by the dial gage. This thesis was compared with the observed data to the existing research result of the reinforced earth retaining wall. In result an important factor affecting the stability of the reinforced earth retaining wall was the friction force between soil and soil, soil and reinforcing strips, the strength of the strips. The observed maximum tensile stress of the strip by the experiments did not coincide with the theoretical Rankine's failure surface wupposing the straight line and we know that the more internal friction of a sand backfill is large, stability of retaining wall is larger.

How a Fit between Software Engineers and Organizational Cultures Motivates them?
최영근 한국경영교육학회 2014 경영교육연구 Vol.29 No.3
All fields of software engineering have been interested in motivation model of software engineers for long time. These studies are mainly interested in personal issues however, organizational issues for the motivation of software engineers have been overlooked. This study illuminated a fit between software engineers and organizational culture to motivate them. Agreeing to the psychological contract approaches of organizational culture types and considering the characteristics of software engineers, I proposed three organizational culture types which motivate software engineers. This study used survey methodology and received responses from 352 software engineers working 34 companies in Korea. The results of this study supported that result-oriented, open oriented and employee oriented culture increase their affective organizational commitment affecting turnover intention negatively in turn.

As we move forward in the 21st century, new challenges are appearing associated with the complexity of manufacturing products and component interdependence; as the complexity of a system is increasing, the performance of the system is increasingly affected by the interaction among the components of the system (interdependence). When the interdependence is neglected, performance of a system is overestimated. To design and analyze systems effectively, the interdependence among the components in the system has to be considered. This paper focuses on developing a framework for an optimum design and performance analysis based on reliability in which the performance of the system and its components are affected by the interactions of its components. To validate the proposed algorithm, a real world case study is presented, and system reliability with interdependence consideration is evaluated.

최근 원격 회의 시스템에서 마이크로폰 어레이를 이용한 음원 위치 추정 및 음질 향상 기술이 연구되고 있다. 이러한 기술 가운데 대표적인 정합 필터 마이크로폰 어레이는 다수의 마이크로폰을 이용하여 음원의 위치를 추적하고 음원의 방향으로부터 입사되는 신호만을 수신할 수 있도록 한다. 그러나 이는 음향 공간의 기하학적인 형태 및 재질 등을 이용한 모델로부터 미리 계산된 음향 채널을 사용하기 때문에 실제 실내 환경과의 불일치로 인하여 성능이 저하된다. 본 논문에서는 수신된 음향 신호로부터 실내 음향 채널을 추정하고 이를 정합 필터 마이크로폰 어레이에 적용하였다 연구된 방법은 실험을 통해 그 성능을 고찰하였다. Recently, speaker localizing estimation technique has been rising in teleconference systems. In this paper, it was described to be able to enhance the speech quality through microphone array, and received the only signal of speaker. Unfortunately, as it using estimated the signal in advance, it is not matched in a real acoustic environment so it has poor performance. In this paper is proposed for Adaptive Matched Filter Microphone Array that estimated acoustic room environment from the received the signal and study of the efficiency through simulations.

차량 운전석 설계 시 운전자의 선호 운전자세와 체압분포가 중요하게 고려되고 있다. 운전석 설계에 운전자세와 체압분포를 효율적으로 고려하기 위해 대표 착좌전략 유형을 분류한 연구들이 수행되었으나, 유형 분류시 시각적인 기준에 의해 분석되었으며 유형의 특성에 대한 연구가 부족하였다. 본 연구는 운전자의 착좌전략 유형을 정량적으로 파악하기 위해 여성 20명과 남성 20명의 운전자세와 체압분포를 측정하고 군집분석을 통해 유형을 분류하였다. 운전자세 기반의 착좌 전략 유형 분류 결과, 상체와 하체 각 3가지(상체: reclined, erect, slouched; 하체: knee bent, knee extended, upper-leg lifted) 전략으로 분류되었으며, 체압분포 기반의 착좌전략 유형 분류 결과, 상체와 하체 각각 3가지(상체: mid-back & scapular, mid-back & lumbar, lumbar; 하체: hip concentrated, hip & mid-thigh concentrated, hip & mid-thigh distributed) 전략으로 분류되었다. 운전자세 기반 상체 착좌전략은 성별에 영향을,하체 착좌전략은 OPL type의 영향을 받는 것으로 파악되었으나, 체압분포 기반 착좌전략은 성별 또는 OPL type의 영향을 받지 않는 것으로 파악되었다. 또한, 운전자세 및 체압 분포 기반의 착좌전략 유형간 연관성 분석결과, 서로간의 연관성이 유의하지 않은 것으로 나타났다. 이는 체압분포 기반의 착좌전략이 운전자세 이외에도 seat cushion의 물성,seat configuration, 운전자 신체 특성 등의 요소에 의해 영향을 받기 때문인 것으로 추정된다. 본 연구에서 분류된 착좌전략 유형은 차량 운전석의 OPL 설계와 seat cushion의 물성 설계에 유용하게 활용될 것으로 기대된다.

The purpose of this study is to investigate if three kinds of internet media addiction influence employees’ job satisfaction and organizational citizenship behavior. Further, this study examines the impact of workplace stress on internet media addiction and if perceived organizational support can be an organizational factor moderating the relationship between workplace stress and three kinds of internet media addiction. To this end, this study collected data from 305 employees in Korean companies through a survey method. Results showed that first, the more stressed employees become in the workplace, the more they are likely to become addicted to social network services, video games, or internet pornography. Second, the more employees become addicted to social network services, video games or internet pornography, the weaker their job satisfaction or organizational citizenship behavior. Finally, when employees have higher perceived organizational support in the workplace, workplace stress has a weaker impact on the three kinds of internet media addiction.
