        옴니채널 무인주문결제시스템의 심리적 저항 요인에 관한 실증적 연구

        김유리,문용은 한국인터넷전자상거래학회 2018 인터넷전자상거래연구 Vol.18 No.6

        The aim of the research is to investigate the resistance factors about consumer acceptance of Unmanned Order Payment System on Omni Channel based on Ram's 'Innovation Resistance Model'. The research was conducted based on a survey of 311 consumers aged between 10 and 60, and the Frequency Analysis, Descriptive Statistics Reliability Verification, Factor Analysis, and Multiple Regression Analysis are carried out using SPSS 20.0. The results of this research are as follows. First, the perceived resistance factors of consumers appeared in order of 'perceived risk' > 'complexity' > 'reversibility' > 'consumer innovation'> 'relative advantage'. Second, Multiple Regression Analysis was performed by setting five consumer resistance factors (relative advantage, complexity, reversibility, consumer innovation, and perceived risk) as independent variables and setting innovation resistance as dependent variable. As a result, it was found that the higher complexity and reversibility and perceived risk, the more innovation resistance increased. And the higher relative advantage and consumer innovation, the more innovation resistance decreased. Third, among the consumer resistance factors, the highest influence factor on innovation resistance was 'Complexity', followed by 'relative advantage', 'consumer innovation', 'returnability' and 'perceived risk'. This is analyzed as complexity of order and payment process in actual usage is the biggest factor make consumers recognize the most concerned part as 'perceived risk' when using the Omni Channel's Unmanned Order Payment System to resist the new system.

        청계천복원사업의 조경설계안 변경 요인 분석

        김유리,양병이,Kim, Yu-Ri,Yang, Byoung-E 한국조경학회 2007 韓國造景學會誌 Vol.35 No.5

        In this study, the implications for landscape architecture in the restoration Project of Cheonggyecheon will be shown through the analysis of factors for landscape architect scheme modification. The method of study consists of theoretical study, analysis of the plan and design of landscape architecture of the restoration project of Cheonggyecheon, and deduction of implications thereof. The controversial feints included the many difficulties in realizing the productive design of landscape architecture due to the selective collecting of public opinion and the problems of settling the complications, the design limit of the turnkey and MA systems, the lack of hydraulic knowledge and technology and the shortage of vegetation monitoring data and experimental materials. The alternative proposals are as follows: 1) there should be agreement between the government organization and the civil group, 2) in the turnkey bidding for the river restoration projects, the river restoration design based on the volume divided into some parts should be reconsidered in order to maintain consistency in the total design, 3) in order to maintain consistency in the planning policies, MA designs should also be introduced and applied from the first stage of the project through its completion, and 4) data such as the safe water level in case of flooding for the facilities and the vegetation and data in connection with the ecological restoration of river should be accumulated. If these controversies are not settled effectively, the river restoration project will be delayed due to complications with the citizens and wasted time and effort will result from the frequent design changes. In addition, landscape architecture in this kind of restoration project is bound to decrease in the future due to frequent changes in the hydraulic-centered design.

        Relation of Anemia to Echocardiographically Estimated Left Ventricular Filling Pressure in Hypertensive Patients Over 50 Year-Old

        김유리,편욱범,신길자 한국심초음파학회 2010 Journal of Cardiovascular Ultrasound Vol.18 No.3

        Background: Anemia is associated with worse long term outcomes in heart failure. However, there is little evidence on the effect of low hemoglobin level to the left ventricular (LV) structure and diastolic function in hypertensive patients. This study assessed the relationship of hemoglobin level to LV filling pressure in elderly hypertensive patients. Methods: From January 2005 to January 2009, 200 newly diagnosed hypertensive patients over 50 years old (mean age 60 ±6 years, 116 women) were analyzed. The clinical parameters and comprehensive echocardiographic data were obtained. The patients with and without anemia were compared. Results: There were significant differences between the anemic and non-anemic groups in the LV mass index (115.27 ±34.95 vs. 103.75 ± 28.21 g/m2), left atrial (LA) volume index (29.31 ± 10.74 vs. 24.99 ± 7.43 mL/m2), and E/E’ (11.92 ±4.34 vs. 9.37 ± 2.51). Chronic renal failure was more prevalent in anemic group. On multivariate logistic analysis, anemia was significantly correlated with high LV filling pressure, reflected by E/E’, even after controlling for LV mass index and LA volume index. Furthermore, E/E’ was significantly correlated with the hemoglobin level (R2 = 0.093, p < 0.001). Conclusion: In newly-diagnosed hypertensive patients over 50 years old, the presence of anemia was significantly associated with elevated LV filling pressure and LV structural changes. And the hemoglobin level was negatively correlated with noninvasively estimated LV filling pressure.

        광릉 수문연구부지 내 원두부 소유역에서 지하수면의 주기적 변동 특성

        김유리,우남칠,이상덕,홍태경,김준,Kim, Yu-Lee,Woo, Nam-C.,Lee, Sang-Duck,Hong, Tae-Kyung,Kim, Joon 한국지하수토양환경학회 2008 지하수토양환경 Vol.13 No.1

        광릉 수문연구부지 내 원두부 소유역에서 천부 관측정 G1, G4를 대상으로 2006년 2월부터 10월까지 5분 간격으로 관측한 지하수위 변동자료에 대한 주기적 변동원인과 그 영향을 분석하였다. 지하수위는 일주기의 반복성을 보이며, 겨울에서 여름으로 갈수록 변동폭이 증가하였다. 지하수위 관측 자료의 파워스펙트럼 분석 결과, 24.38시간의 일주기 성분과 12.19시간의 반일주기 성분이 나타나며, 이는 각각 지구 조석 성분 중 $P_1$ 분조와 $L_2$ 분조에 근접하다. 일주기 성분은 겨울에 비해 여름에 더 큰 power를 나타내어 지하수위가 조석 뿐 아니라 증발산에 의한 영향까지 함께 받고 있음을 보여준다. 또한 강우 직후의 지하수위 자료에서는 일주기 성분이 감소하는 현상 역시 일주기 성분에 증발산이 큰 영향을 미치고 있음을 지시한다. 조석과 증발산에 의한 지하수위 변동은 일주기 성분이 $0.4{\sim}4.2$ cm, 반일주기 성분은 $0.2{\sim}0.7$ cm 정도의 영향을 미친다. Periodic fluctuation of water levels were analyzed for their causes and effects on groundwater movement. Groundwater levels were monitored from two shallow monitoring wells, G1 and G4, located at a headwater catchment in the Gwangneung Ecohydrological Research Site using pressure transducers with automatic data-loggers by five-minute interval from February to October, 2006. The water table fluctuates on a daily basis with a clear diurnal variation, and the fluctuation amplitude increases with time from the winter to the summer. Results from spectral analysis of water-level data show periodic variations in 24.38 hour and in 12.19 hour, indicating $P_1$ diurnal and $L_2$ semidiurnal tidal components, respectively. The diurnal component of the water level in summer has greater power than that in winter, implying that the water table is affected not only by earth tides, but also by evapotranspiration. Right after rain stops, the power of diurnal component of the water level decreases, indicating that evapotranspiration influences significantly diurnal periodicity. The effects of diurnal and semidiurnal components of the water level range from 0.4 to 4.2 cm and from 0.2 to 0.7 cm, respectively.

        내부연결방식 임플랜트 시스템의 삼차원 유한요소법적 연구

        김유리,조혜원,이재봉,Kim Yu-Lee,Cho Hye-Won,Lee Jai-Bong 대한치과보철학회 2006 대한치과보철학회지 Vol.44 No.1

        Statement of problem: Currently, there are some 20 different geometric variations in implant/abutment interface available. The geometry is important because it is one of the primary determinants of joint strength, joint stability, locational and rotational stability. Purpose: As the effects of the various implant-abutment connections and the prosthesis height variation on stress distribution are not yet examined this study is to focus on the different types of implant-abutment connection and the prosthesis height using three dimensional finite element analysis. Material and method. The models were constructed with ITI, 3i TG, Bicon, Frialit-2 fixtures and solid abutment, TG post, Bicon post, EstheticBase abutment respectively. And the super structures were constructed as mandibular second premolar shapes with 8.5 mm, 11 mm, 13.5 mm of crown height. In each model, 244 N of vertical load and 244 N of $30^{\circ}$ oblique load were placed on the central pit of an occlusal surface. von Mises stresses were recorded and compared in the crowns, abutments, fixtures. Results: 1. Under the oblique loading, von Mises stresses were larger in the crown, abutment, fixture compared to the vertical loading condition. 2. The stresses were increased proportionally to the crown height under oblique loading but showed little differences with three different crown heights under vertical loading. 3. In the crown, the highest stress areas were loading points under vertical loading, and the finish lines under oblique loading. 4. Under the oblique loading, the higher stresses were located in the fixture/abutment interface of the Bicon and Frialit-2 systems compared to the ITI and TG systems. Conclusions: The stress distribution patterns of each implant-abutment system had difference among them and adequate crown height/implant ratio was important to reduce the stresses around the implants.

        자기통제력 발달 양상과 자기시간활용 및 학업능력의 종단적 변화

        김유리 인하대학교 교육연구소 2017 교육문화연구 Vol.23 No.6(A)

        본 연구에서는 학생의 자기통제력 발달양상을 확인하고, 자기통제력 잠재계층을 탐색하며, 도출된 자기통제력 잠재계층에 따른 학생들의 자기시간활용(독서시간, 수면시간, 여가시간, TV시청시간, 게임시 간, 개인학습시간) 및 학업능력(학습방법, 학습노력, 학습태도, 학업성취도)의 종단적 변화를 살펴보고자 하였다. 이를 위해 서울교육종단연구(Seoul education longitudinal study; SELS)의 초등학생 6학년 패널자료 (3차~7차년도, 2012년~2016년)를 활용하였다. 연구 결과, 첫째, 성장혼합모형(growth mixture modeling; GMM)을 통해 5년 동안 학생들의 자기통제력에 대한 발달양상을 확인하였고, 둘째, 5개의 자기통제력 잠재계층(평균유지집단, 상위유지집단, 하위유지집단, 지속감소집단, 지속상승집단)을 확인하였다. 마지 막으로, 다집단 성장혼합모형(growth mixture model with known class multiple group analysis)을 통해 5개 자기통제력 잠재계층에 따른 자기시간활용 및 학업능력의 종단적 변화를 확인하였다. 본 연구 결과는 자기통제력을 이용한 학습 및 개인시간 활동에 유익한 참고 및 지도 자료가 될 것이며, 무엇보다도 자기통제력에 대한 학교현장의 이해를 구하는 데 도움이 될 것으로 기대된다. The purpose of this study is to explore the latent classes of students’ self-control, the predictors for the latent classes in the individual characteristics (personal time, academic ability), and the longitudinal change in the individual charactreristics of the latent classes. To do this, this study used the 6th grade panel data (3rd to 7th year, 2012 to 2016) of elementary school students in the Seoul Education Longitudinal Study. The results of this study, first, through 5 years growth mixture modeling(GMM), confirmed the developmental aspects of self-control ability within five years. Second, five latnet classes(average maintenance group, upper maintenance group, sub-maintenance group, sustained decrease group, sustained upward group) were identified. Finally, this study identified the longitudinal change of personal time and academic ability according to the five latent classes derived through growth mixture model with known class multiple group analysis. The result of this study is expected to be a basic material to consider differential educational approach according to age, cognitive, affective, and behavioral characteristics of students in the development of self-control.
