In this paper a sensitivity analysis about effects of influencing factors on the stability of soil cut and embankment slopes in field was performed. Slope stability analysis of slopes in field was carried out with dry, rainy and seismic conditions. As results of analyzing the sensitivity of factors for the dry and rainy conditions, effect of cohesion, internal friction angle and unit weight of soil on the stability of cut slope is more critical in the dry condition than in the rainy condition. However, their effects on the stability of embankment slope for both conditions are similar to each other. The horizontal seismic coefficient does also affect the stability within the similar range of values irrespective of dry or rainy conditions. Cohesion and internal friction angle are more dominant factors influencing the slope stability irrespective of dry or rainy conditions than unit weight of soil and the horizontal seismic coefficient.

Microscopic simulation models, which focus on individual vehicles, are used extensively in the transportation operations in order to capture vehicle to vehicle and vehicle to traffic controls. There are many important factors involved when a micro simulation model is applied as an evaluation tool for the traffic system. They typically include test bed, software, simulation time period, measure of effectiveness, parameter for a software, OD matrix, and random seed number. To evaluate the effects of those factors, sensitivity analysis was performed to identify the effects of those factors based on CORSIM and TRANSIMS results. Three freeway corridors, two in Houston (I-10 and US 290) and one in Sin Antonio (I-37), were chosen as test beds. Three time periods (AM, PM, off-peak) and three OD matrix estimates were used for the analysis. It was found that the micro-simulation results were highly sensitive to the model Parameter sets and the OD information. The degree of sensitivity was a function of the test bed and time period.

The purpose of this study was to analyze the effect of automatic exposure control (AEC) control factors in digital radiography systems based on the fine contrast images using coin phantoms. The AEC control factors were targeted at the range of dominent zone, sensitivity, and density. The dominent zone was divided into cases where a single coin was used to cover the field configuration, and cases where seven coins were used to cover the field configuration. The sensitivity was classified into three stages (200, 400, 800) and the density was classified into three stages (2.5, 0, 2.5). Image quality was evaluated by signal to noise ratio (SNR) and contrast to noise ratio (CNR). Then, the automatically exposed tube current was measured. As a result, the X-ray image of seven coins obtained a result value of about 1.2 times higher for SNR and 1.9 times higher for CNR than the X-ray image for one coin. The tube current was also about 1.6 times higher. In conclusion, In AEC, the higher the field configuration and dominent zone are matched and the higher the density, the lower the sensitivity, which increases the tube current and CNR, which increases the image quality. Therefore, it is judged that the appropriate setting of the range of dominent zone, sensitivity, and density of the control, which is the AEC control factor, could improve the fine contrast of images.

The objective of this study is to analyze factors affecting purchase intention and conduct price sensitivity analysis of Korean Shine-muscat for Chinese consumers. Logit model has been set up to find purchase intention with survey data which was conducted in Beijing China. The results show that the high-income, unmarried consumers are more sensitive to the price of Korean Shine-muscat than low-income, married consumers, but have higher purchase intention. Also, consumers who perceive Korea positively and those who prefer Korean dramas are more sensitive to the price but have higher purchase intention. Consumers with a high monthly purchase frequency of Shine-muscat have higher purchase intention of Korean Shine-muscat, but are more sensitive to the price. The results of this study can be utilized as basic information for promoting the export of Korean Shine- muscat to China.

For the application of the neutron flux mapping, an accurate calculation of the sensitivity is required because the sensitivity is proportional to the neutron flux density. Sensitivity is defined as the current per unit length per unit neutron flux and it mainly depends on the depression factor(f), the escape probability from the emitter($\varepsilon$1) and the charge build-up factor of the insulator layer(c). A Monte Carlo simulation was accomplished to calculate the sensitivity of rhodium emitter material and alumina(Al$_2$O$_3$) insulator with a cylindrical geometry, based on the (n,${\beta}$) interaction and on other interaction including the secondary electron generation for the more accurate estimation of the sensitivity. From the simulation results, factors fur the sensitivity were accurately calculated and compared with other theoretical and experimental values. In addition, the sensitivity linearly increases and saturates as the emitter radius increases. The accomplished method is useful in the analysis for the change of SPND sensitivity as a function of burn-up and in the optimum design of SPND.

Ethical sensitivity is a basic competency required for nursing students to work as professionals who will care patients in the clinical field after graduation. Therefore, efforts are needed to improve the knowledge on ethical sensitivity in undergraduate education. This study aimed to identify the demographic characteristics that influence ethical sensitivity among nursing students. This study was a secondary analysis that referred to a previous work measuring ethical sensitivity in nursing students. The participants were 128 nursing students, who had experienced clinical practicums. Among the participants, those who were third-year (t=2.345, 95% CI=[1.24, 14.64], p=0.021), female (t=2.635, 95% CI=[3.65, 25.69], p=0.009) and were satisfaction with major (t=-2.389, 95% CI=[-16.54, -1.50], p=0.019) consistently reported significantly higher mean scores on ethical sensitivity. The explanatory power of the model was 13.3%. Gender (Exp (B)=0.875, 95% CI=[0.804, 0.952], p=0.002) and year at universtiy were the strongest predictors of ethical sensitivity (Exp (B)=0.921, 95% CI=[0.873, 0.971], p=0.002). Based on the results, an appropriate ethics education that considers the following issues should be provided for undergraduate nursing students: both genders' perspectives, seniors' further development, and students experiencing low satisfaction with their major. Future nursing education should consider these individual demographic characteristics to develop nursing students' ethical sensitivity that will further affect their ethical behavior and ultimately improve the quality of nursing.

The objective of the study is to analyze the relative performance of factors affecting indoor air quality in multi-residential buildings in Korea. A study of the factors affecting indoor air quality is essential for establishing indoor air quality management strategies effectively. To observe the indoor air quality response following a modification of a given parameter, a sensitivity analysis was performed. The factors examined for the analysis include; wall/ceiling paper, adhesive for wall/ceiling paper, floor material, adhesive for floor material, and ventilation rate. The Experimental Design which identifies main effects among the design parameters with a few experiments was used to decrease the number of experiments. The simulation for indoor air quality was undertaken using a validated equation. Then, ANOVA(Analysis of Variance) was performed to evaluate the relative importance of each parameter affecting the indoor air quality. The result of the study indicates that the indoor air quality may be influenced most by adhesive for wall/ceiling paper, followed by ventilation rate and adhesive for floor material.
