This study examined the effects of interpersonal relationship harmony and stress coping on the college adjustment among nursing students. The participants were 231. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and multiple regression. Adjustment to college life significantly correlated with interpersonal relationship harmony and stress coping style. Interpersonal relationship harmony was significantly different according to year, satisfaction with nursing as a major, and academic achievement. Multiple regression analysis showed that interpersonal relationship harmony and stress coping(problem-focused, emotion-focused, hopeful thought) explained 23% of variance in adjustment to college life. The study findings suggest that intervention intended to promote nursing students' adjustment to college life should focus on improving interpersonal relationship harmony and stress coping.

The purpose of this study was to examine the relationships among dementia knowledge, empathy, attitudes toward to dementia in caregivers of older adults with dementia. Data were collected 147 caregivers who worked in long term care centers. The self-report questionnaire was used for data analysis. SPSS Win. 21.0 was used to analyze data via descriptive statistics, Pearson correlation coefficient, and multiple regression. The mean score of dementia knowledge was $20.18{\pm}3.58$ out of 30, and the means of empathy was $82.12{\pm}9.68$ out of 105 and the means of dementia attitudes was $96.45{\pm}13.72$ out of 140. Attitudes toward dementia in caregivers differed significantly depending on their age, motivation of job. Attitudes also had a positive correlation with dementia knowledge and empathy. The most significant preditors of attitudes were empathy, job of motivation and age. These factors explained 33.0% of the variance for attitudes toward dementia. Above results suggest that dementia education programs depending on age, job of motivation, and empathy level is needed.

The purpose of this study is to investigate the relationship of job stress and job satisfaction according to leisure activity type of nurses. The subjects were from August 1, 2017 to August 15, 2017 for nurses working in general hospitals in B, K city. Data were analyzed by frequency, percentage, mean and standard deviation, t-test, ANOVA, and Pearson's Correlation coefficient. Job stress was slightly lower than the middle level and job satisfaction was slightly higher than the middle level. Job stress was negative correlated with the number of leisure activities per week in types of leisure activity, and job satisfaction was not related. In conclusion, in order to reduce job stress of nurses, it is necessary to increase the number of leisure activities per week and further study is needed for various nurses in a wide area.

Unlike domestic railway transportation system in which majority of station are equipped with gate access controller and ticket office, it has been a very common practice in overseas railway transit or railway station that they use a pressure door mat, infrared-sensors or CCTV cameras so as to automatically determine the number of passenger onboard and alight and to reflect the information to their business (i.e., deployment of vehicles and human resources). The data collected by the automatic passenger counting (APC) system provides methods how to obtain the information about the number of passenger using the vehicles on the basis of date, time and stop(station) which enables large-scaled transit company to create profits through effective vehicle deployment and management of their employees. This paper addresses the basic features of the automatic passenger counting system using infrared sensor and describes those of the extended APC system in conjunction with wireless technologies such as GPS, WLAN or Cellular network.

The demand of wireless communication system is increasing due to the development of computers and other digital media appliances. In particular, new wireless communication technology is necessary for implementation of home network since a lot of data transmission is occurred. Recently, two wireless communication technologies, Ultra Wide Band(UWB) and 60GHz band wireless communication technology, have being developed for high-speed data transmission and Wireless Personal Area Network(WPAN). In this paper, we study the present development condition of these two technologies and a role of them in home network. We also suggest the method to implement the home network using all wireless communication technologies. At the end, we outlook the market of WPAN and High Definition Multimedia Interface(HDMI).

XML can effectively express structured or semi-structured data as well as relational databases. XQuery is a query language for retrieving information for such an XML document. In this paper, an XQuery composer is designed and implemented, with an API provided for XQuery processors, and a proper processor is registered. This composer shows query results immediately processed by the processor. As this composer contains a parser for XQuery, it can compose XQuery effectively using a diverse dialog box designed for XQuery grammar. A dialog box is affiliated with a clause region, which is a region that algebra operates from the parsing tree. It can compose path expressions for an XML document easily as it shows an element tree from DTD graphically. Path expressions are composed automatically by marking elements in the structural hierarchy and by specifying the predicate of an element partially.

As the number of various types of media data such as UCC (User Created Contents) increases, research is actively being carried out in many different fields so as to provide meaningful media services. Amidst these studies, a semantic web-based media classification approach has been proposed; however, it encounters some limitations in video classification because of its underlying ontology derived from meta-information such as video tag and title. In this paper, we define recognized objects in a video and activity that is composed of video objects in a shot, and introduce a reasoning approach based on description logic. We define sequential rules for a sequence of shots in a video and describe how to classify it. For processing the large amount of increasing media data, we utilize Spark streaming, and a distributed in-memory big data processing framework, and describe how to classify media data in parallel. To evaluate the efficiency of the proposed approach, we conducted an experiment using a large amount of media ontology extracted from Youtube videos.

This paper describes a head pose estimation method using PTZ(Pan-Tilt-Zoom) camera. When the external parameters of a camera is changed by rotation and translation, the estimated face pose for the same head also varies. In this paper, we propose a new method to estimate the head pose independently on varying the parameters of PTZ camera. The proposed method consists of 3 steps: face detection, feature extraction, and pose estimation. For each step, we respectively use MCT(Modified Census Transform) feature, the facial regression tree method, and the POSIT(Pose from Orthography and Scaling with ITeration) algorithm. The existing POSIT algorithm does not consider the rotation of a camera, but this paper improves the POSIT based on perspective projection in order to estimate the head pose robustly even when the external parameters of a camera are changed. Through experiments, we confirmed that RMSE(Root Mean Square Error) of the proposed method improve $0.6^{\circ}$ less then the conventional method.
