Purpose: The purpose of this study was to identify the effect of the exchange of saline used in surgical procedures on surgical site infections. Method: Patients with stomach cancer were assigned to the experimental group or to the control group by random sampling, respectively. The experimental group received an exchange of saline during the operation right after the excision of the stomach in a gastrectomy but the control group did not. Data were collected from the medical charts of 34 patients from Dec. 1, 2002 through May 31, 2003. Result: The surgical site infection rate of the experimental group was 5.9% while surgical site infection rate of the control group was 17.6%. In total, the surgical site infection rate was 11.8%. The experimental group maintained a normal level of WBC on post operative day 3; however, the control group, showed an increase of WBC on post operative day 3. Conclusion: The exchange of saline used in an operation immediately after the excision of the stomach in a gastrectomy decreases the contamination level of saline used in the operation, and can prevent surgical patients from a surgical site infection.

The research was to investigate the effect of quality cognition(usage, medical information, aesthetic, safety) of the web site of the facility on customer loyalty and moderating role of trust variable. The respondents was 201 patients and caregivers. Data were collected from March 1 to 31, 2010 at C university hospital in G city. In relationship between quality cognition of facility web site and customer loyalty, the results of quality cognition on customer loyalty showed 43.1% (F=36.912) in model 1, 46.3%(F=33.454) in model 2, and 46.8%(F=18.580) in model 3. In relationship between web site quality cognition and customer loyalty, moderate effect of trust was not considerable. As results, quality is the leading fact for customer loyalty more than trust. Therefore, customer loyalty leaves its possibility of increment when facility web site is designated depending on medical information, usage and aesthetic.

Ground subsidence in urban areas due to excessive development and degraded underground facilities is a serious problem. Geophysical surveys have been conducted to estimate the distribution and scale of cavities and subsidence. In this study, electrical resistivity tomography (ERT) was performed near an area of road subsidence in an urban area. The subsidence arose due to groundwater leakage that carried soil into a neighboring excavation site. The ERT survey line was located between the main subsidence area and an excavation site. Because ERT data are affected by rapid topographic changes and surrounding structures, the influence of the excavation site on the data was analyzed through field-scale numerical modeling. The effect of an excavation should be considered when interpreting ERT data because it can lead to wrong anomalous results. A method for performing 2D inversion after correcting resistivity data for the effect of the excavation site was proposed. This method was initially tested using a field-scale numerical model that included the excavation site and subsurface anomaly, which was a loosened zone, and was then applied to field data. In addition, ERT data were interpreted using an existing in-house 3D algorithm, which considered the effect of excavation sites. The inversion results demonstrated that conductive anomalies in the loosened zone were greater compared to the inversion that did not consider the effects of excavation.

Based on the 4-compartmental pharmacokinetic model developed in PART1, target-controlled infusion(TCI) pump system was designed and evaluated. The TCI system consists of digital board including microcontroller and digital signal process(DSP), analog board, motor-driven actuator, user friendly interface, power management and controller. It provides two modes according to the drugs: plasma target concentration and effect target concentration. Anaesthetist controls the depth of anaesthesia for patients by adjusting the required concentration to maintain both plasma and effect site in drug concentration. The data estimated in DSP include infusion rate, initial load dose, and rotation number of motor encoder. During TCI operation, plasma concentration. effect site concentration, awaken concentration, context-sensitive decrement time and system error information are displayed in real time. Li-ion battery guarantees above 2 hours without power line failure. For high reliability of the system, two microprocessors were used to perform independent functions for both pharmacokinetic algorithm and motor control strategy.

Prior research highlighted personalized services as a crucial antecedent to website loyalty, yet little has been discussed on the underlying mechanism. The current study explores the intervening effects of the three psychological constructs in the personalization-loyalty relationship: cognitive efficiency, perceived enjoyment, and socialness. An experiment was conducted with a total of 414 U.S. shoppers on a fictitious e-tail site for jeans that employed different levels of personalized content. The results found that the participants exposed to the high-level personalization condition reported a higher cognitive efficiency and higher socialness perception regarding the fashion e-tail site; however, no direct effect of intensity of e-personalization was found on perceived enjoyment. Cognitive efficiency and enjoyment perceptions on the site significantly increased customers' loyalty intentions regarding the site, while website socialness perception had no direct effect on loyalty intentions. Website socialness showed indirect effects on website loyalty intentions only through cognitive efficiency and perceived enjoyment; however, no direct effect from website socialness was found. Implications and limitations of the study were discussed.

Earth fissures with several kilometers will inevitably approach or cross the metro line, significantly threatening the safety of the underground structure in the earth fissure site. However, the influence of the earth fissure site's amplification effect on the metro station's dynamic response is still unclear. A representative earth fissure in Xi'an was taken as an example to establish a numerical model of a metro station in the earth fissure site. The dynamic response characteristics of the metro stations at different distances from the earth fissure under various seismic waves were calculated. The results show that the existence of the earth fissure significantly amplifies the dynamic response of the nearby underground structures. The responses of the axial force, shear force, bending moment, normal stress, horizontal displacement, inter-story drift, and relative slip of the metro station were all amplified within a specific influence range. The amplification effect increases with the seismic wave intensity. The amplification effect caused by the earth fissure has relatively weak impacts on the axial shear, shear force, bending movement, normal stress, and horizontal movement; slightly larger impacts on the inter-story drift and acceleration; and a significant impact on the relative slip. The influence ranges of the axial force and normal stress are approximately 20 m. The influence ranges of the acceleration and inter-story drift can reach 30 m. Therefore, the seismic fortification level of the underground structure in the earth fissure site needs to be improved.

Activating e-commerce, studies about trust of business acquaintance are actively made. This study measured the effect of trust transfer setting up 6 situations according to linking direction, design standard and grasping their trust changes for surveying trust transfer on online. The result is that trust transfer becomes different in accordance with the linking direction of hyperlink. In other words, setting up target site as comparative subject, it is more reliable than single site. Setting up source site as comparative subject, trust changes are slight. This study is composed of 6 good site and 6 poor site. And trust transfer by hyperlink on online is consistent, especially trust transfer is affected by not source site but target site. If target site is poorer than source site, trust transfer originate definitely. So we can draw consistent conclusion that it rate higher than single site. On the other hands, if targer site is better than source site, trust transfer occurs not inter-website. Instead, affected by human mentality, it rates good site higher by conformity reversion.

본 연구에서는 UCC 사이트의 신뢰를 형성하는 신뢰요인들을 세 가지(정보신뢰, 시스템 신뢰, 서비스 신뢰)로 구분하고, 이러한 세부 신뢰 요인들이 UCC 사이트 전체의 신뢰에 어떤 영향을 미치는 지를 분석하고자 한다. 세 가지 신뢰요인들 중 어떤 요인들이 UCC 사이트 신뢰에 더 많은 영향을 주는지 파악할 수 있을 것이며, 이러한 신뢰가 UCC서비스 이용에 미치는 영향도 UCC참여 수준에 따라 달라질 수 있음을 제시하고자 한다. 왜냐하면, UCC자체가 참여를 전제로 하나 참여하는 소비자로서의 조회에 비해 생산자로서의 수정, 재생산, 창작단계에서는 자신의 노력, 시간, 비용이 많이 요구되기 때문에 신뢰가 더욱 중요하게 된다. 만약 신뢰하지 못한다면, 절대 자신의 노력과 시간, 비용을 투자하면서 자신의 창작물을 생산하거나 공유하려고 하지 않을 것이기 때문이다. 338개의 분석 자료가 가설 검증을 위해 사용되었고 분석결과 정보 신뢰, 시스템 신뢰, 서비스 신뢰가 UCC사이트 신뢰에 긍정적인 영향을 미치는 것이 유의하게 나타났으며 아울러 UCC사이트 신뢰가 UCC사용에 유의한 긍정적 영향을 미친다는 것으로 나타났다. 그러나 UCC참여 수준에 따른 UCC사용에 미치는 UCC사이트의 영향은 유의하지 않게 나타났다.
