In this paper, we proposed a Sequential Download System(SDS) to provide high steaming QoS in p2p network. SDS is able to receive a media file simultaneously from multiple source peer by download manager and deal with unexpected leave of source peer. Also It can provide stable streaming services with minimum buffering delay and manage request of other peer by memory map in process of downloading.

The purpose of this study was to investigate the impact of nursing college students' empathy and communication ability on college life adaptation. The study targeted 177 nursing students from two university in G city. Data collection was conducted from May 16 to June 9, 2023. Data analysis utilized SPSS 25.0, including frequency analysis, mean and standard deviation calculations, independent t-tests, one-way analysis of variance (ANOVA), and post-hoc analysis using Scheffé's test. Results: The mean scores of empathy was 2.49(SD=0.54), communication ability were 3.24(SD=0.67), and college life adaptation was 3.83(SD=0.55). There were significantly positive correlations between college life adaptation and empathy(r=.348, p< .001), communication ability(r= .351, p< .001), Factors affecting participants' college life adaptation were empathy(𝛽= .240, p= .002), and communication ability(𝛽= .246, p= .002), which explained about 16.0% of the college life adaptation. Based on these findings, it is believed that it is necessary to develop curricular and extracurricular programs and find ways to efficiently utilize them to empathy and good communication skills in nursing students.

Vehicular communications have been receiving much attention in intelligent transport systems(ITS) by combining communication technology with automobile industries. In general, vehicular communication can be used for vehicle-to-vehicle(V2V) and vehicle-to-infrastructure( V2I) communication by adopting IEEE802.11p/1609 standard which is commonly known as wireless access in vehicular environment(WAVE). WAVE system transmits signal in 5.835~5.925 GHz frequency band with orthogonal frequency division multiplexing(OFDM) signaling. In this paper, after 32 bit processed the channel monitoring in MAC(Media Access Control) layer of WAVE system implemented according to IEEE 802.11p standard, data were received and we evaluated the performance, we built the test bed consisting of OBU(On Board Unit) in the real expressway. We transmitted WSM(WAVE Short Message) and received WSM between OBU wirelessly. And then, we calculated channel occupancy time per one frame and throughput, and evaluated the performance.

The purpose of this study is to confirm the effect of simulation practice education applied to nursing students on communication competency, critical thinking tendencies, and professionalism. This study is a one-group pre-post test design-like experimental design study, and 89 fourth graders of the Department of Nursing at one university were targeted. Data collection was from September to December 2019. The collected data were analyzed through frequency and percentage, mean, standard deviation, paired t-test, and Pearson correlation using the SPSS 20.1 program. As a result of the study, the subject's communication competency after simulation practice training (t=3.41, p<.001), critical thinking tendency (t=2.75, p<.007), professionalism was found to have increased statistically significantly (t=2.56, p<.012). After simulation practice, it was found that communication competency, critical thinking tendencies, and professionalism each had a positive correlation.

Purpose: The aim of this study was to determine the factors that influence safe sexual behaviors of Korean young adults and identify differences by gender. Methods: This study aimed to determine which factors affected safe sexual behaviors based on the Theory of Planned Behavior. Data from 437 Korean young adults (in their 20s and 30s) were collected via online survey between January 3 and January 28, 2022. The questionnaire included items on sexual body image, sexual role perception, sexual attitudes, sexual socialization, sexual communication, and safe sexual behaviors. Structural equation modeling was performed. Results: According to the overall model fit of the hypothetical model, the final model was acceptable and explained 49% of safe sexual behaviors. Sexual attitudes (β=h-.70, p<.001) and sexual communication (β=.53, p<.001) directly affected safe sexual behaviors, and sexual role perception (β=.42, p<.001) indirectly affected safe sexual behaviors in a combined model. There were gender differences in the path from sexual attitudes (β=-.94, p<.001) and sexual communication (β=.66, p<.001) to safe sexual behaviors and from sexual body image (β=.27, p<.001) to sexual communication. Conclusion: Sexual attitudes and sexual communication were predictors of safe sexual behaviors, which differed by gender. Strategies that consider sexual attitudes, sexual communication, sexual role perception, and differences between men and women should be developed to improve the safe sexual behaviors of young adults.

This study examined the relationship among smartphone addiction, life stress, and family communication in nursing students. A total of 172 subjects participated in this study and the data were collected using the structured questionnaires. The collected data were analyzed using an independent t-test, ANOVA, Pearson's correlation coefficient, and multiple linear regression using the SPSS WIN 19.0 program. Overall, the level of stress was high, time of family communication was short, and smartphone addiction rate was high in nursing students. The high risk group of smartphone addiction was 14.0%, potential risk group was 29.0%, and normal group was 57.0%. In the risk group, the life stress was higher (t=3.15, p=.002) and family communication was not better (t=-2.53, p=.012) than the normal group. Smartphone addiction correlated significantly with life stress (r=.27, p<.001) and family communication (r=-.26, p=.001). The factors affecting smartphone addiction were smartphone usage time, life stress, importance of smartphones in their lives, and family communication, and the explanatory power was 31.3%. Based on these results, it is necessary to develop personalized and collective customized intervention programs focused on smartphone using method, life stress management, and family communication for the prevention and management of smartphone addiction of nursing students.
