Objectives: Health threats from smoking are still not diminishing worldwide. As part of efforts to reduce the smoking population, advertising communications through various media is one of the major anti-smoking campaigns, such as efforts to improve the environment of other institutions. With the development of remarkable media technology, communication through Social Network Service (SNS) has become a part of our lives. The purpose of this paper is to explore effective ways of smoking cessation advertising by comparing the persuasive effects of smoking cessation messages on Facebook and existing print media that have a great influence on the communication environment. Methods: The threat appeal in advertising has been proven to have an effect on leading to the intention of quitting smoking. There are two ways of threat appeal: personal harm threat appeal and social welfare threat appeal, and facebook and print media. Check the persuasive effect of the advertising message when loaded in the medium. Four types of experimental advertisements are exposed to 241 male and female subjects to verify the persuasive effect of SNS and traditional print media. Results: The threat appeal advertisement of personal harm was more persuasive than the social welfare threat advertisement in the smoking cessation attitude. In perceived behavioral control factors, which included the concept of self-confidence, the threat of personal harm threat claims was significantly higher than that of social welfare threat appeals. Personal harm threat claims and social benefit threat claims on Facebook have a greater impact on perceived behavioral control than print media. Lastly, subjective norms including the concept of ambient pressure perceived by smokers were the most influential factors influencing smoking intentions. Conclusions: Threat appeal is still valid for smoking cessation advertisements, and in combination with SNS media, effective smoking cessation and behavior can be induced. In addition, SNS should be distinguished from traditional media, and the advantages of SNS media should be appropriately utilized.

In this study, adsorption/desorption characteristics of uranium ion was investigated using an anion exchangeresin. After anionization of uranyl(UO2 2+) ion, batch tests were conducted using A500/2788 as an anion exchange resin. Adsorption tests were conducted for various concentrations of acid, temperatures, concentrations of uranium ions and adroption times whereas desorption tests were conducted for various concentrations of H2SO4 and reaction times. According to test results, the highest adsorption of uranium ion was obtainde in 0.01 M H2SO4 solution while the adsorption decrease in the strong acidic solution. Also, the adsorption rate was found to adsorption capacity. Furthermore, the adsorption results were found to respond well to Langmuir isotherm equation and follow the pseudo second-order kinetic model. In case of desorption tests, the high desorption was obtained in concentrated H2SO4 solutions. Desorption of more than 70% was obtained at the beginning of 60 minutes while the desorption rate decreased gradually and reached to the equilibrium after 6 hours. 본 연구에서는 음이온교환수지를 사용하여 우라늄 이온의 흡탈착특성을 고찰하였다. 따라서 uranyl(UO2 2+) 이온을 음이온화한 후 음이온교환수지 A500/2788을 이용하여 산농도, 온도, 우라늄의 농도, 반응시간에 따른 흡착실험과 황산농도, 반응시간에 따른 탈착실험을 수행하였다. 실험결과, 황산 0.01 M에서 가장 높은 흡착률을 보였으며 농도가 높아질수록 흡착률은 감소하였다. 반응온도가 증가할수록 흡착반응속도는 증가하였으나 최대흡착량에는 영향을 미치지 않았다. 한편, 흡착등온실험결과, 본 흡착은 Langmuir 등온식에 부합하며, 반응속도는 2차임이 확인되었다. 황산의 농도에 따른 탈착실험에서는 농도가 증가할수록 탈착률이 높아졌으며, 초기 60분 동안 70%이상 탈착이 이루어진 후 탈착속도가 점차 감소하여 6시간이후 탈착평형에 도달하였다.
