This study is to examine the relationships between emotional labor, job stress, and job burnout of staff accountants. The results of the analysis are as follows. First, frequency of emotional display has a negative impact on job stress, but emotional dissonance is not associated with job stress statistically. And all types of emotional labor(emotional display, emotional variety, emotional dissonance) have no significant effects on job burnout. Second, all types of emotional labor have no significant impacts on job burnout. Third, full mediation by job stress is proved in the relations between frequency of emotional display and job burnout and between emotional variety and job burnout. But emotional labor doesn`t directly impact on job burnout but it influences job burnout via job stress indirectly. These results provide a meaningful framework and theoretical basis for future research on emotional labor, job stress, and job burnout.

In order for location information to deliver the collected information, it needs Sensor Nodes in an environment of Sensor Network. Each sensor sends data to a base station through the process of routing in a wireless sensor network environment. Therefore, Offering accurate location information is very important in a wireless sensor network environment. Most of existed routing methods save all the informations of nodes at the area of 1-hop. In order to save these informations, unnecessary wasted energy and traffics are generated. Routing Protocol proposed in this paper doesn`t save node`s location information, and doesn`t exchange any periodic location information to reduce wasted energy. It includes transmission range of source nodes and nodes with the location information, however it doesn`t include any nodes` routing near 1-hope distance.

Cross Site Scripting enables hackers to steal other user`s information (such as cookie, session etc.) or to do abnormal functions automatically using vulnerability of web application. This attack patterns of Cross Site Scripting(XSS) can be divided into two types. One is Reflect XSS which can be executed in one request for HTTP and its reply, and the other is Stored XSS which attacks those many victim users whoever access to the page which accepted the payload transmitted. To correspond to these XSS attacks, some measures have been suggested. They are data validation for user input, output validation during HTML encoding procedures, and removal of possible risk injection point to prevent from trying to insert malicious code into web application. In this paper, the methods and procedures for these two types are explained and a penetration testing is done.

An array DBMS has been expected widely from scientists because it is convenient to store and analyze the data of array type. In this paper, we describe how to handle satellite remote-sensing images in the array DBMS. However, previous works in their visualization have two problems as follows. First, the images are visualized as a state of distorted by the curvature of the earth. Second, it is difficult to apply the results of visualization by pre-written queries to other analyses. Therefore, this paper proposes a three dimensional visualization method of satellite remote-sensing images, not traditional 2D visualization. Our research contents are as follows. First, we describe how to store, process, and analyze the satellite remote-sensing images in the array DBMS. Second, we propose a three-dimensional visualization method for their processed outputs. Lastly, our contributions can be summarized that we propose a method of handling satellite remote-sensing images in the array DBMS and their 3D visualization techniques. It is also expected that their use be available widely in many industrial areas.

This study was conducted to develop a severity-adjusted LOS(Length of Stay) model for knee replacement patients and identify factors that can influence the LOS by using the Korean National Hospital Discharge in-depth Injury Survey data. The comorbidity scoring systems and data-mining methods were used to design a severity-adjusted LOS model which covered 4,102 knee replacement patients. In this study, a decision tree model using CCS comorbidity scoring index was chosen for the final model that produced superior results. Factors such as presence of arthritis, patient sex and admission route etc. influenced patient length of stay. And there was a statistically significant difference between real LOS and adjusted LOS resulted from health-insurance type, bed size, and hospital location. Therefore the policy alternative on excessive medical utilization is needed to reduce variation in length of hospital stay in patients who undergo knee replacement.

We investigated the student`s satisfaction in team activities. The 64 engineering college freshmen were grouped into 13 teams, and a set of questionnaire was given and analyzed. The results showed that the overall team satisfaction positively affects the team performance. However, the team satisfaction is more correlated with the team member`s participation and the relationship. The team satisfaction tends to increase when having an environment where the team members regard each other, which they felt more important than the outcome. The particular role of team members was not directly related to the team satisfaction, and the students prefer having self-control in team formation. By using the study results, we may support students to have a positive experience of team learning especially in convergence educational environment.

This paper aims to propose the typology suitable for games by analyzing the fashion styles of game characters and define the characteristics by type. The data collected was classified into the style groups with similarities, and the game character styles were named using representative terms. Then, five styles were identified and analyzed with the focus on clothing, hairstyle, and accessories: Creative Style, Attractive Style, Grotesque Style, Usual Style, and Suit Style. Creative Style was the unique style with partial addition or removal as the creative design. Attractive Style expressed the sexual attraction by design with significant exposure of body parts and skintight design. Grotesque Style showed grotesque, eerie, and dreary design. Usual Style was a plain and practical style. Finally, Suit Style was a kind of armor covering the whole body.
