Despite the creative strengths fashion illustrations, most fashion related advertisements use photographs instead. Furthermore, there is not much study done on the effects of fashion illustrations. Through this study the authors discover the effectiveness of fashion related magazine advertisements using fashion illustrations by looking into the level of recognition due to interaction effects between advertisements using photographs and advertisements using fashion illustrations. This study, however, does not focus on comparing the different levels of recognition effect between photographs and fashion illustrations. After a literature review of magazines with high rank subscriptions, an experiments was conducted. A booklet was made using 16 fashion illustration advertisements and 16 photograph advertisements all designed to control variables other than advertisement type. Then a survey was taken using the booklet to measure the recognition levels of the different types of advertisements. Through an ANOVA test of the 2 ${\times}$ 3 factorial designed model the authors derived results implying that interaction effects do exist between the different types of advertisements. In the environment where advertisements using photographs dominate, advertisements using fashion illustrations can effectively be recognised by the consumers. Through this study, the authors wish to give guidance to decision makers in the fashion industry related to the type of printed advertisement they should seek.

The study on the performance of the nonlinear friction tuned mass dampers (FTMD) for the mitigation of the seismic responses of the structures is a topic that still inspires the efforts of researchers. The present paper aims to carry out a numerical study on the optimum tuning of TMD and FTMD parameters using a multi-objective particle swarm optimization (MOPSO) algorithm including soil-structure interaction (SSI) effects for seismic applications. Considering a 3-story structure, the performances of the optimized TMD and FTMD are compared with the uncontrolled structure for three types of soils and the fixed base state. The simulation results indicate that, unlike TMDs, optimum tuning of FTMD parameters for a large preselected mass ratio may not provide a best and optimum design. For low mass ratios, optimal selection of friction coefficient has an important key to enhance the performance of FTMDs. Consequently, a free parameter search of all FTMD parameters provides a better performance in comparison with considering a preselected mass ratio for FTMD in the optimum design stage of the FTMD. Furthermore, the SSI significant effects on the optimum design of the TMD and FTMD. The simulation results also show that the FTMD provides a better performance in reducing the maximum top floor displacement and acceleration of the building in different soil types. Moreover, the performance of the TMD and FTMD decrease with increasing soil softness, so that ignoring the SSI effects in the design process may give an incorrect and unrealistic estimation of their performance.

The principal objective of this study was to assess the effects of food involvement moderating the relationship between food choice motives, including health concerns, weight control and ethical concern, and fruit consumption. A total of 290 questionnaires were completed. Moderated regression analysis was utilized to assess the relationships among variables. The results of the study showed that the results of data analysis also indicated good model fit. The direct effects of health concerns on fruit consumption were statistically significant in Models 1 and 2. However, the direct effects of ethical concern on fruit consumption were statistically significant in Model 3. As had been expected, the interaction of ethical concerns and food involvement exerted a significant effect on fruit consumption in Model 3. However, the interaction of health concern and food involvement, as well as weight control and food involvement exerted no significant effects on fruit consumption. Moreover, ethical concerns about fruit consumption exerted a significant negative effect at the low level and a positive effect at the high level of food involvement, except in cases in which the level of food involvement was medium. The results of this study revealed that fruit marketers should attach importance to the interaction effect of food involvement in order to better understand the elements of market demand and customer loyalty.

The nonlinear free vibration of a nanorod subjected to finite strain is investigated. The governing equation of motion in material configuration in terms of displacement is determined. By means of Galerkin method, the Fourier series solutions satisfying some typical boundary conditions are determined. The amplitude-frequency relationship and interaction between the modes are studied. The effects of nonlocal elasticity are shown for different length of nanotubes and nonlocal parameter. The results show that nonlocal effects lead to additional internal modal interaction for nanorod vibrations.

This study examines effects of Facebook on language learning in terms of facilitating interaction and collaboration by applying Facebook in a Korean language class. Forty one exchange students from seventeen countries who participated in the study used Facebook to exchange information and complete group projects. Results show that Facebook was effective in sharing class materials, engaging in class community and collaborating to complete assignments. Students also comment that socializing with peers was helpful, yet more activities and discussion to draw active participation is needed. This study also points out the important role of instructors who implement social media and manage the class.

This paper compares domain combination based protein-protein interaction prediction method with domain based protein-protein interaction method. The prediction accuracy and reliability of the methods are compared using the same prediction technique and interaction data. According to the comparison, domain combination based prediction method has showed superior prediction accuracy to domain based prediction method for protein pairs with fully overlapped domains with protein pairs in learning sets. When we consider that domain combination based method has the effects of assigning a weight to each domain interaction, it implies that we can improve the prediction accuracies of currently available domain or domain combination based protein interaction prediction methods further by developing more advanced weight assignment techniques. Several significant facts revealed from the comparative studies are also described in this paper.

This study investigated differences in toddlers' language development depending on their teachers' types of interaction during reading of picture books. A pilot study identified teachers' types of interaction as instructional, non-immediate, and passive. Fifteen teachers recruited from 10 child-care centers located in Seoul and their 90 2-year-old toddlers participated in this study. Teachers read two picture books to a small group of toddlers each week for eight weeks. Data on the toddlers' receptive and expressive language, vocabulary, reading behavior, and book handling were collected and compared by their teachers' interaction type before and after teachers' 8-week reading of picture books. Results showed that teachers using the non-immediate interaction type had the most positive effects on toddlers' language development.

The mechanism of interaction of four coumarin derivatives (CDS) with bovine serum albumin (BSA) was studied using spectrofluorometric technique. It was found that the coumarin ring common to all CDS makes major contribution to interaction. Binding affinities could be related to parachor values of CDS. Stem-Volmer plots indicated the presence of static component in the quenching mechanism. Results also showed that both tryptophan residues of protein are accessible to CDS. The high magnitude of rate constant of quenching indicated that the process of energy transfer occurs by intermolecular interaction forces and thus CDS binding site is in close proximity to tryptophan residues of BSA. Binding studies in the presence of the hydrophobic probe, 8-anilino-l-naphthalein-sulfonic acid showed that there is hydrophobic interaction between CDS and the probe and they do not share common sites in BSA. Thermodynamic parameters obtained from data at different temperatures showed that the binding of CDS to BSA involve hydrophobic bonds predominantly. The effects of various metal ions on the binding of CDS with BSA were also investigated.
