This study was a cross-sectional descriptive research that investigate the level of addiction and analyzed the impact of computer game addiction from 20 to 30 years old on communication capabilities. The purpose of this study was to investigate the level of game addiction according to general characteristics and to confirm the effect of computer game addiction on communication ability. There were a total of 220 participants in the study. This survey for this study was a self-reporting questionnaire, research tools for this study were developed by Lee (2000) using game addiction and Communication ability developed by Frits et al., (1999). Data analysis was analyzed with frequency analysis, t-test, ANOVA, and Regression using SPSS 18.0. As a result of analysis, the difference between game addiction and communication ability by gender was appeared to be different under statistical significance levels: game addiction (t=-.9.2, p<0.01), subcomponents of communication ability, concentration (t=7.20, p<0.01), understanding (t=6.13, p<0.01), response (t=6.22, p<0.01), memory (t=2.88, p<0.05). The highest level of game addiction was appeared between 28 and 30 years old under statistical significance (p<0.01). Finally computer game addiction affects understanding, a subcomponent of communication capabilities.

The P2P is a network environment supporting data exchange which is directly connected peers without limit of existing server-client and intervening central server for resource or offered service with each peer. JXTA is a representative of P2P system. JXTA is a typical distributed computing model that proposed by Sun Microsystems. JXTA that doesn't require centralized services or resources is adaptable in extreme changes of network organization. MANET(Mobile Ad Hoc Network) is a representative wireless network that is composed of mobile nodes without infrastructure. So MANET establishes the path for the communication of each peers and maintains the newest routing information by exchanging routing information. In this paper, we propose a technique of JXTAMAUET which implements JXTA which is the P2P network system from the wireless network which is becoming the foundation of ubiquitous computing. For the performance evaluation of the JXTAMANET, we use simulation.

Purpose : This descriptive research study aimed to identify the factors influencing nursing students' empathy and gender role identity and their effect on communication competence. Methods : Participants were 183 senior nursing students who had completed a clinical practice and simulation-based practical training course. Using the IBM SPSS/WIN 21.0 program, general characteristics were analyzed using descriptive statistics, independent variables were compared with t-tests and 𝑥² tests, and influencing factors on each variable and communication underwent multiple linear regression analysis. Results : Communication competence showed significant correlations with empathy (r=.40, p<.001), gender role identity (r=.53, p<.001), major satisfaction (r=.18, p=.013), and peer relationships (r=.24, p<.001). When gender was entered as a covariate, empathy (t=4.41, p<.001) and gender role identity (t=6.97, p<.001) were identified as predictors affecting communication competence with 36% explanation power (R²=.36, p<.001). Conclusion : The findings of this study suggest that course subjects considering the gender identities of students should be developed through various programs to establish students' identity as nurses and improve their empathy and communication.

The purpose of this study was to provide basic information for developing effective marketing strategies of nursing organization by identifying the influence of internal marketing factors on the nurses' organizational commitment. The subjects of this study were 256 nurses who were working in the hospital over 1 year at three university hospitals which had more than 400 beds in seoul and kyung-gido. The data were collected by self-reporting questionnaires. The instruments used in this study were the communication form scale developed by Jo(1995), the welfare scale developed by researcher, the education training scale developed by researcher, the organizational commitment scale developed by Mowday, Porter and Steers(1979). The data were analysed by the SAS package using frequency, percentage, mean, standard deviation, Pearson's correlation coefficient and stepwise multiple regression. The results of this study were as follows; 1. In mean score of internal marketing factors in nursing organization, horizontal communication was 3.42, downward communication 3.32, involvement communication 3.08, upward communication 3.00, education training 2.54, welfare 2.51. The meas score of organizational commitment was 3.00. 2. Organizational commitment was positively correlated with upward communication(r=0.48, p=0.0001), education training(r=0.42, p=0.0001), horizontal communication(r=0.36, p=0.0001), welfare(r=0.34, p=0.0001), involvement communication(r=0.25, p=0.0001) of internal marketing factors in nursing organization, but was negatively correlated with downward communication(r=-0.20, p=0.0014). 3. The major internal marketing factors which influence organizational commitment was upward communication. Upward communication explained 23% of organizational commitment. If education training, horizontal communication, welfare and downward communication were added, 38% of the variance would be explained. In conclusion, the results of this study showed that the higher upward communication level among the internal marketing factors was doing more important role in nurses' organizational commitment. Therefore, for improvement of nurses' organizational commitment, it is important to improve upward communication and to develop the education training program among the internal marketing factors.

Objectives : The purpose of this study was to help form treatment relationship with patient through more effective communication by defining the relationship between dental hygienist's medical communication and outpatient's reliance satisfaction. Methods : The study researched 273 male and female patients who visited dental clinics and hospitals of Busan from March 12 to March 26, 2012 and its results are as follows. Results : 1. The linguistic communication of dental hygienist was $3.72{\pm}0.63$ and non-linguistic communication was $3.48{\pm}0.58$. 2. For the dental hygienist's reliance satisfaction, the reliance was $3.62{\pm}0.65$ and the satisfaction was $3.74{\pm}0.65$. 3. The dental hygienist's communication degree depending on general characteristic was statistically significant when the job of patient was housewife(p<0.001) and the number of dental clinic visits was more than 10 times (p<0.000). The dental hygienist's non-linguistic communication was statistically significant depending on patient's gender(p<0.000), age(p<0.002), job(p<0.001) and number of dental clinic visits (p<0.000). 4. The dental hygienist's reliance and satisfaction showed statistically significant difference depending on patient's gender(p<0.000), age(p<0.002), job(p<0.001) and number of dental clinic visits (p<0.000). 5. The dental hygienist's non-linguistic communication showed a positive correlation with reliance and satisfaction(p=0.000). Conclusions : When considering the result above, it is necessary to develop the teaching method and material to educate the communication ability of dental manpower. It is necessary to reinforce the curriculum of dental hygienics and the education of dental hygienist to perform effective, smooth communication between dental hygienists.
