The purpose of this study was to investigate the influence of nurse's compassionate competence and burnout on their communication behavior with dementia patients. The subjects of this study were 190 nurses who were taking care of patients with dementia at long-term care hospitals and who agreed with the survey. The collected data were analyzed by descriptive statistics, t-test, ANOVA, Pearson Correlation Coefficient, and multiple regression. The communication behavior of nurses caring for dementia patients was found to have a significant correlation with compassionate competence and burnout. Multiple regression analysis showed that nurses' compassionate competence and burnout affected communication behavior, and the total explanatory power was 31%. It is suggested that the results of this study can be used as basic data for developing programs to improve communication behavior with patients with dementia.

This paper describes the algorithm of computing thermal contact conductance between unmatched grid interfaces for finite element thermal analysis. Because grid interfaces should be coincident with adjacent meshes for finite element method, large amount of man hours and huge computations are required to match interfaces between many numbers of complex subdomains. A novel method that distributes feasibly the conductances to interface nodes is proposed. The aims of the method are described, and details of the nodal conductance distribution algorithm with less dependency on meshes are represented. The algorithm can be applied both the flat and curved interfaces in 3 dimensional space, and proposed method can combined with many finite element application including thermal analysis.

In this paper, we introduce some issues to implement an agent system to support service mobility in home network environment, and describe detailed design method in terminal as well as server agent. Specifically, we describe user recognition module, signaling message receiving/parsing module of terminal agent and signaling message receiving/parsing module, multimedia switching module, memory management module of server agent. We define several parameters managed in IP sharing device and design binding table structure to support mobility. And we utilize M/M/1/K queueing theory to obtain relations between memory size, blocking probability and memory utilization. From the obtained results, we show that memory size can be predicted in server agent mounted on IP sharing device.

In this paper, we propose a fast object classification method based on texture and color information for video surveillance. We take the advantage of local patches by extracting SURF and color histogram from images. SURF gives intensity content information and color information strengthens distinctiveness by providing links to patch content. We achieve the advantages of fast computation of SURF as well as color cues of objects. We use Bag of Word models to generate global descriptors of a region of interest (ROI) or an image using the local features, and Na$\ddot{i}$ve Bayes model for classifying the global descriptor. In this paper, we also investigate discriminative descriptor named Scale Invariant Feature Transform (SIFT). Our experiment result for 4 classes of the objects shows 95.75% of classification rate.

Recently, the use of locational information is growing rapidly. GPS technology has been adopted generally for obtaining locational information in outdoor spaces. In the other hand, the researches on indoor positioning have been carried out applying WLAN, RFID or Bluetooth technology because of the multi-path interference of GPS signal caused by the physical obstacles such as walls or columns in buildings. However, such technologies for indoor positioning cost too much to build sensing infrastructure and compute-intensive processes are involved. Furthermore, the accuracy of location estimation is variable caused by interior structures in buildings. In this study, to make up for the limitations, descriptive data such as phone number, unique room numbers, or business names readily available in mixed-use buildings is used for extracting location information. Furthermore, during the process, a geocoding method using character matching is applied to this study enabling prompt location estimation and sublating the fluctuation of accuracy caused by interior structures. Based on the proposed method in this study, an architecture is designed, and three-dimensional viewer program is developed for the implementation of this study. Also, this research is quantitatively analyzed through match rate and processing time of proposed method.

This study examined the influence of self- efficacy for smoking cessation, depression, social support and nicotine dependency in the college male smoker. This survey design was adopted for 149 male college students in Gyeongbuk. Data were gathered from September 7 to 18, 2016. Data was analyzed for descriptive statistics, t-test, ANOVA, Pearson correlation, and multiple regression. There was a significant positive correlation between depression and nicotine dependency. There was a significant negative correlation between self-efficacy for smoking cessation and nicotine dependency and between social support and nicotine dependency. The significant factors influencing nicotine dependency were self-efficacy for smoking cessation and depression. This model explained 34% of variance in nicotine dependency. The results suggest that an intervention program is needed to reduce the depression and to increase the ability of self-efficacy for smoking cessation in the college male smoker.

In this paper, we investigate the conventional topological interference management (TIM) with proposed network topology such as 8 trigram (8 user networks). The key observation is that optimal symmetric degree of freedom (DoF) can be achieved for 8 user network with different channel coherence times by adaptively selecting the interference alignment scheme via controlling the alignment feasibility of the transmitted signals. However, this yields a very complex problem, for which we use the combination of different schemes such as interference avoidance and repetition coding. In addition to the above schemes, we propose a triangular transmit cooperation (TTC) algorithm for 8 user networks to achieve the optimal symmetric DoF. And We apply the principle of complementarity of 8 trigram to remove the interferences, and correspond the concepts of win-win and conflict to direct and indirect signals of transmit and receive respectively. We find that the principle of complementarity comes out from the trigram of I Ching. That is, we apply the relation of confrontation and coexistence to 8 transmitters and receivers, and get the results of symmetric DoF of 4/3.

This study concerns of how the Qing dynasty overcame the national inferiority on the process of the Ming-Qing war in the East Asia during the early 17th century. Historically the Qing came forward in succession the total 12 Emperors whose posthumouses were recorded according to a respective independent system. These studies will be commented the alliance between Manchurian and Mongolian tribes. As the researching result, it will be commented that the Qing's emperors possessed the names of the Emperor of Han's race, Khan of Mongolian tribe, Han of Manchurian clan at the same time. Furthermore in other to follow the war against the Ming dynasty the Qing dynasty promoted positively the strategic alliance through the marriage connection with Mongolian royal family. And the Qing dynasty succeeded in organizing the Military Eight Banners so that Qing dynasty could utilize the reorganized social civilian groups into the avaliable groups to the battle. Thus this Eight Banners were comprehended all members who were not only the Mongolian clans allianced but also the submitted soldiers from the Ming in the war.
