Purpose: To develop and apply an integrative model for breast cancer survivors’ return to work, survivors’ unsatisfied demands for job maintenance were identified.Methods: This study was a qualitative research that used a focus group to investigate breast cancer survivors’ unsatisfied demands for job maintenance. Data collection was conducted four times from February to October 2019 with six participants.Results: The study showed that the six participants identified the following unsatisfied demands for breast cancer survivors who returned to work: the individual’s physical and psychological condition, attitudes and support from family, work-related characteristics, the healthcare system, and social (political) issues. Thirteen sub-topics were identified.Conclusion: This study provided necessary data to prepare a strategy for breast cancer survivors to return to work and proposed to develop an integrative model and a professional training program in further research.

To prepare relatively large negatively charged polymer particles in a size range from 0.3 μm to 0.5 μm, having high surface charge densities, the heteroaggregation of small (50–100 nm), highly charged (185 and 421 μeq/g) anionic polystyrene particles onto the surface of larger (317–466 nm) poly(vinylbenzyl choride)‐based cationic (10, 614, and 830 μeq/g) particles was carried out. As a result, particles with different surface charges, having a core‐shell structure, were successfully prepared. First, aggregated particles were formed via heteroaggregation of the lowest surface charge density anionic particles (185 μeq/g) with the lowest surface charge density cationic particles (10 μeq/g). However, the anionic particles in the shell layer desorbed with time owing to the relatively weak interaction between the two particles. Second, aggregated particles comprised of the highest surface charge density cationic (830 μeq/g) and anionic latex particles (421 μeq/g) were formed. However, to prepare a stable system, an excess of the small anionic particles was required, leaving a large number of small particles present in the aqueous phase, which proved difficult to remove. Finally, aggregated particles were formed by heteroaggregation of cationic particles with an intermediate surface charge density (614 μeq/g) with the highest surface charge anionic particles (421 μeq/g). As a result, not only were core‐shell particles formed, but few free small anionic particles remained in the aqueous phase. In this article, the preparation and characterization of each of these aggregates are discussed in terms of particle size, morphology, and extent of incorporation of the functional groups. © 2012 Wiley Periodicals, Inc.
