Purpose: This study was to explore the effects of breast cancer education for college students on their mother's breast cancer screening promotion. Methods: This study used a one-group pretest and posttest design. Data were collected from September to November, 2007 from a sample of 80 college students and their mothers using a survey questionnaire, which asked about demographic variables, concerns over health and breast cancer, communication, stage of change and attitude (pros and cons) related to breast cancer, and confidence in breast self-examination. The college students received education about breast cancer for 50 minutes and then they educated their mothers about breast cancer. Data were analyzed with descriptive statistics and paired t-test. Results: The mean age of the college students was 22.0 years, and that of their mothers 49.4 years with a range from 43 to 58 years. After receiving education on breast cancer, there were significant changes in the mean scores of concerns about health and breast cancer, communication, pros in mammography, and confidence in practicing breast self-examination. Conclusion: This study indicates that education on breast cancer to mothers through their college-age daughters is effective and can be utilized to promote breast cancer screening for women.

Purpose: This study attempted to identify influential variables on smoking temptation between groups: adolescent smokers and adult smokers. Method: A survey was conducted with 376 adolescent smokers in 4 high schools and 451 adult smokers in community settings in South Korea. Univariate statistics and regression were used for data analysis. Result: The most powerful predictor of smoking temptation for adolescent smokers was nicotine dependency. On the other hand, the most powerful predictor of smoking temptation for adult smokers was self-efficacy for smoking abstinence. In the high smoking temptation group, depression and nicotine dependency were the predictors for smoking temptation for adolescent smokers and nicotine dependency and pros for smoking were the predictors for smoking temptation for adult smokers. In the low smoking temptation group, cons for smoking and process of change for smoking abstinence were the predictors on smoking temptation for adolescent smokers and self-efficacy for smoking abstention and pros for smoking were the predictors on smoking temptation for adult smokers. Conclusion: There were different influential variables on smoking temptation according to age groups and level of smoking temptation. Smoking-cessation interventions should be tailored to the level of smoking temptation of the individual smokers.

This study was carried out to assess the perception of decisional balance of Korean women toward mammography screening. From Dec. 20, 1998 to Apr. 30, 1999, a samples of 1,903 subjects were selected from 7 metropolitan areas and 6 provinces of Korea. Data was collected using Rakowski et al's decisional balance scale to measure the decisional balance regarding a woman's adoption of mammography screening and to assess the woman's current stages of adoption of mammography. The classification of women according to the stage of adoption of mammography was 54.9 % in precontemplation, 31.9 % in contemplation, 7.8 % in action, and 5.5 % in maintenance. The mean difference of pros, cons, and the decisional balance by the stage of mammography adoption were statistically significant. There were significant mean differences between the stages of adoption according to a woman's experience with and intention for mammography and the pros score, the cons score, and the decisional balance score. The behavioral portion of stage of mammography adoption provides a further level of discrimination. Results provide the empirical evidence for the Transtheoretical model.

Objective: This descriptive, cross sectional study was conducted to examine the effect of levels of self-efficacy on children's perceptions of pros and cons of smoking. Methodology: The sample was 233 fifth-grade students. Data were collected in September 2010 using the Socio-Demographic Data Collection Form, Self Efficacy Scale Child Form and Child Decision Balance Scale and analyzed via percentage calculations and t test with the SPSS 11.00 statistical package program. Results: Average age of the students participating in the research was $11.1{\pm}0.41$, 49.8 % (n: 116) being female and 50.2 % (n:117) male. The difference between the score averages of the pros of smoking perceptions of children with a high self-efficacy level and of those with a low self efficacy level (t=2.117, p=.042) and the difference between the score averages of the cons of smoking perceptions of children with a high self-efficacy level and of those with a low self-efficacy level (t=2.206, p=.035) were found to be statistically significant. Conclusions: Children's positive perceptions of smoking were low and negative perceptions high when their self efficacy levels were high. Conversely, children's positive perceptions of smoking were high when their self efficacy levels were low.

In apartment buildings, casualties, especially fatalities have occurred in balcony areas in fires if residents fail to escape to the main entrance. Potential consequences of a particular infrequent event should be considered. In attempting to design apartment buildings for fire safety, alternative escape methods such as vertical penetration could be considered. The purpose of this study is to investigate present building regulations regarding apartment buildings and examine pros and cons of the current escape method and alternative escape methods. Focus group interview was conducted to discuss problems of fire escape methods. In addition, questionnaires were distributed to field professionals working in architecture, construction and related industries. Among 500 questionnaires distributed, 192 questionnaires were collected. Usable 162 questionnaires were analyzed using SPSS 15. Regarding alternative fire escape methods, several concerns were mentioned. Safety, privacy, security, effectiveness of escape, water proof problems were raised. Based on the opinions, vertical penetration between apartment unit appeared more safe, secure, effective than horizontal penetration. However, both methods have its own pros and cons under specific contexts. Alternative escape methods need be considered for a selective options for residents in case of fire.

Purpose: This study identified and compared influential variables on intention and action to quit smoking between adolescent smokers and adult smokers. Methods: For the selection of variables, the transtheoretical theory was used. A survey was conducted with 376 adolescent smokers in 4 high schools and 451 adult smokers in community settings in South Korea. Discriminant analysis was used for data analysis Results: The variables of adolescent smokers that predicted an intention to quit smoking were: smoking temptation, self re-evaluation, counter conditioning and stimulus control. The variables that predicted an action to quit smoking were: self-efficacy for smoking abstinence, pros for smoking, self reevaluation, and self liberation. The variables of adult smokers that predicted an intention to quit were: smoking temptation, pros for smoking, cons for smoking, self reevaluation. The variables that self liberation and predicted an action to quit smoking were: self efficacy for smoking abstinence, smoking temptation, and counter conditioning. Conclusions: Developing stage specific smoking intervention methods based on different ways of how individuals make a decision to quit smoking within their contexts needs to be done.

Objectives: This study aims to identify the factors associated with the stages of change in colorectal cancer screening, and develop a model explaining these stages of change by using structural equation modeling analysis. Methods: On the basis of literature review and expert advice, we constructed our hypothetical model that consisted of five theoretical constructs(process of change, pros, cons, self-efficacy, stage of change). In 2009, data was collected from 486 participants aged between 50 and 69. The data were analyzed by SPSS 15.0 and AMOS 6.0. Results: In the case of stage of adoption, the contemplation stage was the most common (37.4%), followed by the action stage (26.5%). In the final model of the stage of change for colorectal cancer screening, there was a direct influence of the process of change ($\gamma$=.562, p<.001), and cons ($\gamma$=.132, p<.01) on the stage of change with the terms of GFI .931, AGFI .904, RMR .038, NFI .930, and NNFI .936. Conclusion: It is necessary to produce and disseminate evidence-based cancer screening information, which can mitigate the negative attitude among the public toward cancer screening. Also, it is essential to provide a safer and more comfortable environment at cancer screening center.

Quorum-based algorithms are widely used for solving several problems in mobile ad hoc networks (MANET) and wireless sensor networks (WSN). Several quorum-based protocols are proposed for multi-hop ad hoc networks that each one has its pros and cons. Quorum-based protocol (QEC or QPS) is the first study in the asynchronous sleep scheduling protocols. At the time, most of the proposed protocols were non-adaptive ones. But nowadays, adaptive quorum-based protocols have gained increasing attention, because we need protocols which can change their quorum size adaptively with network conditions. In this paper, we first introduce the most popular quorum systems and explain quorum system properties and its performance criteria. Then, we present a comparative and comprehensive survey of the non-adaptive and adaptive quorum-based protocols which are subsequently discussed in depth. We also present the comparison of different quorum systems in terms of the expected quorum overlap size (EQOS) and active ratio. Finally, we summarize the pros and cons of current adaptive and non-adaptive quorum-based protocols.

For several years, virtual reality (VR) and augmented reality (AR) technologies have been improving. However, some hurdles remain that slow down the distribution of VR and AR devices, such as head-mounted display (HMD), and related consumer content. One issue is VR motion sickness, which has been experienced by users using 360 degree VR content via HMD. This paper discusses the related international standardization work that classifies the factors causing VR sickness, and proposes the process for VR sickness level evaluation. Among the factors causing VR sickness, many research institutes regard minimizing MTP (Motion-to-Photon) latency as the key enabler to mitigate VR sickness. Thus, this paper introduces research trends of MTP latency measurement and MTP latency mitigation. This paper categorizes the research on MTP latency measurement into 2 categories of hardware-based approach and software code-level approach. The 2 approaches have different pros and cons depending on use-case, purpose, and architecture of each multimedia system. The pros and cons are addressed in this paper. Additionally, the research on mitigating MTP latency with diverse strategies such as proactive computing, caching, and edge server technology is explained, and compared to conventional technologies, shows improved performance.
