The present study explored the roles that assessment orientation(AO) and perceived benefits of drinking to social relationship(PB) play in college students’ social norm acceptance. Specifically, we investigated how the influence of two types of social norms, i.e., injunctive norms(IN) and descriptive norms(DN), on collegiate drinking is moderated by these two variables. A national survey of Korean college students(N = 569) conducted online revealed: 1) greater influence of DN on the amount of drinking when students perceive greater benefits of drinking to their social relationships; 2) greater influence of PB on the amount of drinking among those with higher AO; 3) a significant three-way interaction of AO.DN.PB on the frequency of drinking, Theoretical implications to the social norm research and practical implications to public interventions to reduce collegiate drinking are discussed.

Post-neutron emission fssion product mass distributions are calculated by using pre-neutron emission fssion product yields (FPYs) and neutron multiplicity. A semi-empirical model is used to calculate the pre-neutron FPY, frst. Then the neutron multiplicity for each fssion fragment mass is used to convert the pre-neutron FPY to the post-neutron FPY. In doing so, assumptions are made for the probability for a pre-emission fssion fragment with a mass number A∗ to decay to a postemission fragment with a mass number A. The resulting post-neutron FPYs are compared with the data available. The systems where the experimental data of not only the pre- and post-neutron FPY but also neutron multiplicity are available are the thermal neutron-induced fssion of 233U, 235U and 239Pu. Thus, we applied the model calculations to these systems and compared the calculation results with those from the GEF and the data from the ENDF and the EXFOR libraries. Both the pre- and post-neutron fssion product mass distributions calculated by using the semi-empirical model and the neutron multiplicity reproduce the overall features of the experimental data.

The fission product yields (FPYs) of plutonium isotopes induced by thermal, 500-keV and 2-MeV neutrons are calculated by using a semi-empirical model recently developed and applied to uranium isotopes. In this model, the FPYs are assumed to be proportional to the level density of a compound nucleus at the fission barrier. The fission barrier height that determines the level density is modeled as a sum of a macroscopic term and four microscopic terms. The model has ten parameters, four of which are taken to be the same as those fixed for the uranium isotopes. The remaining six parameters are adjusted to reproduce the FPYs of plutonium isotopes. The resulting parameters for the plutonium isotopes are discussed in comparison with those for the uranium isotopes. The calculated FPYs are compared with experimental and evaluated data, as well as the calculation results from other fission models such as GEF and TALYS. Our semi-empirical model is shown to reproduce the overall features of the FPYs of plutonium isotopes.
Smoking Cessation Apps for Smartphones: Content Analysis With the Self-Determination Theory
Choi, Jounghwa,Noh, Ghee-Young,Park, Dong-Jin JMIR Publications Inc. 2014 Journal of medical Internet research Vol.16 No.2
<P><B>Background</B></P><P>Smartphones are increasingly receiving attention from public health scholars and practitioners as a means to assist individuals’ health management. A number of smartphone apps for smoking cessation are also available; however, little effort has been made to evaluate the content and functions of these apps employing a theoretical framework.</P><P><B>Objective</B></P><P>The present study aims to analyze and evaluate the contents of smoking cessation apps available in South Korea employing the self-determination theory (SDT) as a theoretical framework for analysis. This study analyzes the extent to which smoking cessation apps have features that satisfy the basic needs identified in the SDT, which stimulate autonomous motivation. The type of motivational goal content manifested in the apps and how the goal content was framed are also explored. By assessing the features of smoking cessation apps based on the SDT, this study aims to offer direction for improvement for these apps.</P><P><B>Methods</B></P><P>Out of 309 apps identified from the iTunes store and Google Play (excluding 27 duplications), 175 apps were randomly drawn and analyzed. The coding scheme was drafted by the authors based on the SDT and gain/loss framing theory and was further finely tuned through the process of coder training and by establishing intercoder reliability. Once the intercoder reliability was established, the coders divided up the rest of the sample and coded them independently.</P><P><B>Results</B></P><P>The analysis revealed that most apps (94.3%, 165/175) had at least one feature that tapped at least 1 of the 3 basic needs. Only 18 of 175 apps (10.3%) addressed all 3 basic needs. For goal content, money (53.7%, 94/175) showed the highest frequency, followed by health (32.0%, 56/175), time (7.4%, 13/175), and appearance (1.1%, 2/175), suggesting that extrinsic goals are more dominantly presented in smoking cessation apps. For the framing of goal content, gain framing appeared more frequently (41.7%, 73/175).</P><P><B>Conclusions</B></P><P>The results suggest that these smoking cessation apps may not sufficiently stimulate autonomous motivation; a small number of apps addressed all 3 basic needs suggested by the SDT (ie, autonomy, competence, and relatedness). The apps also tended to present extrinsic goal content (primarily in terms of money) over intrinsic ones (ie, health) by primarily adopting gain framing. Implications of these findings for public health practitioners and consumers are discussed.</P>

Characterization of the particulate matter from three different diesel passenger cars in this study under the vehicle driving cycles and regulatory cycle were analyzed. The vehicles were measured in various vehicle speeds with the aim to verify the particulate number and mass with respect to the road traffic conditions. The total particle number emissions (PNEs) at the lower vehicle speeds increased gradually from the highway to the Seoul metropolis. The results showed that the peak size-segregated bin shifts to the larger particles as diluted exhaust gas is cooled. As the average vehicle speed decreases, the size-segregated peak of particle number concentration (PNC) shifts to smaller particles. The PM composition was mostly composed of both soluble organic fraction (SOF) and soot. The effect of the dilution temperature on the total PNC under the New European Driving Cycle (NEDC) was slightly higher than the dilution ratio. In addition, the nucleation particles (DP: ≤ 13nm) were confirmed to be more sensitive to the dilution temperature rather than other particle size ranges. Comparison with particle composition between vehicle speed cycles and regulatory cycle, sulfate was slightly increased at regulatory cycle, while other components were relatively similar. During cold start, effect of cold environment was an increase in semivolatile nucleation particles, but not solid particles. Research into particle formation dependent on dilution process from diesel passenger cars under the NEDC is important because of verifying impact on vehicular traffic and secondary aerosol formation in Seoul. The results of this study will contribute to improve air quality and human health in Seoul.
