Cluttered background is a major obstacle in developing salient object detection and tracking system for mobile device captured natural scene video frames. In this paper we propose a context aware feature vector selection model to provide an efficient noise filtering by machine learning based classifiers. Since the context awareness for feature selection is achieved by searching nearest neighborhoods, known as NP hard problem, we apply a fast approximation method with complexity analysis in details. Separability enhancement in feature vector space by adding the context aware feature subsets is studied rigorously using principal component analysis (PCA). Overall performance enhancement is quantified by the statistical measures in terms of the various machine learning models including MLP, SVM, Naïve Bayesian, CART. Summary of computational costs and performance enhancement is also presented.

Design history has been thought a secondary studies for design practice. Design historians have been accused of being unimaginative and unadventurous in sticking to dominant types of design such as products, furnitures and graphics. But Design history is still young subject which could be exploited in wide range and topics, and it should be thought a lot of researches could be done. Under this consciousness and circumstance, this study reviews the situation and perspective of design history studies in Korea by critical search on canonical books in the area such as Pevsner's, Banham's, Hesket's, Sparke's, and Chung's those translated into Koreans and Korean originals.

The Lee and Carter method has widely used to forecast mortality because of the simple structure of model and the stable forecasting. The Lee and Carter method, however, also has limitations. The assumption of the rate of decline in mortality at each age remaining invariant over time has been violated in several decades. And, there is no way to include covariates in the model for better forecasts. Here we introduce Park, Choi and Kim method to make up for Lee and Carter's weak points by using two random processes. We discuss structural features of two methods. furthermore, for each method, we forecast life expectancy for 2005 to 2050 using South Korea data and compare the results.

This paper makes a preparatory attempt to reconstruct 'the Korean Science Culture' toward which I think the Koreans should direct and orient themselves rather than describe the history of the science culture in Korea. This task requires us to define 'science culture.' So I propose, based on the definitions of science culture so far made, to consider the model of 'Humanized Science Culture' as a regulating ideal of the Korean Science Culture. To support the model, analyzing the concept of 'science literacy' of the 2061 Project, I posit the model of KDSC (Korean Designer of Science Culture) as the Koreans who will actually come to design the Korean Science Culture. KDSC refers to 'a reasonable man' who will represent a desirable Korean, rather than to a natural Korean. Then I spell out the conditions of becoming a KDSC and scrutinize the philosophical backbones of those conditions. Finally, I make a few suggestions for developing a program of designing and implementing the Korean Science Culture from the viewpoint of a model of KDSC.

The purpose of this study was to apprehend the relationship among self-resilience, critical thinking disposition and academic self-efficacy of nursing student and confirm the influential factors to self-leadership. This study was a descriptive investigation research that conducted data collection through structural survey targeting sophomores from nursing college. As the result, the most influential factor to self-leadership of nursing student was GPA (Grade point average) from last semester followed by critical thinking, necessity of self-leadership program and age, and these variables explained 28.4% of self-leadership of nursing students. Based on the results of this study, we recognize the necessity of self-leadership of nursing students and expect to develop self-leadership program considering general characteristics.

The purpose of this study based on descriptive research is to examine the influences on the self-regulated learning ability due to nursing students' achievement-goal and to make sure mediating effect of autonomous support of professor. A convenience sample of 294 nursing students were recruited from a college in C province from April to May, 2018. Data are analyzed using SPSS/WIN 21.0 program. As a result, it is turned out that there are positive correlation between mastery goal, performance approach goal, self-regulated learning ability and autonomous support of professor. In the Sobel test results, autonomous support of professor had a partial mediating effect between mastery goal and self-regulated learning ability(Z=3.922, p<.001). So, a new teaching method should be developed through the convergence of related factors of self - regulated learning ability.

The purpose of this study was to identify the influence of job esteem and empathy on customer orientation of college nursing students in the convergence society. The participants were 213 college nursing students, data were collected between July to August, 2018. Data were analyzed using t-test, ANONA, Pearson Correlation, Multiple regression. The factors influencing customer orientation were empathy, job esteem, communication with patients, and perception of customer orientation. These factors explained 32.0% of variance in customer orientation. Therefore, in order to improve the customer orientation of nursing students, education courses and intervention for improving cognitive empathy and finding ways to improve job esteem are needed.

The purpose of this study is to investigate the effect of nurse's hospital work environment and supervisor trust on turnover intention. The subjects were 122 nurses in five hospitals in B city and collected data by using giving questionnaire, and used the SPSS 22.0 program to analyze. As a result of the study, there was a positive correlation between the hospital environment and turnover intention (r=534, p<.001), there were negative correlation between hospital work environment and supervisor trust(r=-.232, p=.010), between supervisor trust and turnover intention (r=-.314, p=.001). The factors affecting the turnover intention of nurses were hospital work environment (${\beta}=.505$, p<.001), supervisor trust (${\beta}=-.229$, p=.003), and job position (${\beta}=-.213$, p=.011). Therefore, in order to reduce the turnover intention of nurses, it is necessary to improve the hospital work environment and to establish a strategic program to build and improve supervisor trust.

This paper describes the convergence of the energy technology and information and communication technology (ICT), which helps to consume less energy effectively. While a lot of researches have done against the increase of world energy usage, most of them focus on the efficiency of energy supply, transfer, and consumption equipment. Applying the ICT to decrease energy usage could help to find energy saving factors in the new field that has not been considered as a valuable one before. The big data service with the energy technology and ICT convergence enables correlation analyses of large sets of energy and environmental data. Finding a data tendency with a big data service helps to develop energy saving policies. Furthermore, it could make a further step to develop a new business model. This paper introduces the real cases of the company and project that provides a big data service with the ICT convergence.

In this study, we aimed to identify the relationship between sexual attitude, ego-resiliency, and sexual autonomy in nursing students. The subjects were 226 nursing students who recruited from one college. Data were analyzed using SPSS 20.0 program. The sexual attitude was positively correlated with ego-resiliency (r=.169, p=.011). Also, ego-resiliency and sexual autonomy was positively correlated (r=.148, p=.026). Factors significantly influencing sexual autonomy in nursing students were ego-resiliency (${\beta}=.138$, p=.048), sexual characteristic of participant (${\beta}=-.149$, p=.038), and dating experience (${\beta}=.170$, p=.014). This study showed that the nursing intervention for boosting ego-resiliency and sexual autonomy through healthy and sound dating experience should be required in nursing students.
