BACKGROUND AND OBJECTIVE This study investigated: (1) the prevalence and development of 2 receptive (sexually explicit Internet material [SEIM] use and sexual information seeking) and 2 interactive (cybersex and general social networking site [SNS] use) online behaviors in adolescence; (2) whether development of these behaviors predict adolescents' body and sexual self-perceptions; and (3) whet...

Editor’s Note: Harold C. Seim, MD, MPH, has been the predoctoral director in the Department of Family Practice and Community Health at the University of Minnesota for 12 years. O. Guy Johnson, MD, is a clinical professor in the department and has precepted students in his clinic continuously for the past 30 years.

We developed the theoretical and experimental method for chromatic dispersion of Borosilicate Crown microstructure optical fiber from scalar effective index method (SEIM) and TBC has been reported. To maintain the flat and zero dispersion in photonic crystal fiber (PCF) different air hole diameter has been introduced. Here we use Borosilicate Crown glass as a core material. A photonic crystal f...

This study examined Japanese college students’ (N=476) use of sexually explicit material in mass media (i.e., print, electronic, and the Internet) and its association with their sexually permissive attitudes and perceptions of women. Results indicated that Japanese college students were most exposed to sexually explicit material in the print media followed by the Internet and the electronic med...

Research on the role of sex-related Internet use in adolescents' sexual development has often isolated the Internet and online behaviors from other, offline influencing factors in adolescents' lives, such as processes in the peer domain. The aim of this study was to test an integrative model explaining how receptive (i.e., use of sexually explicit Internet material [SEIM]) and interactive (i.e....

Over the past two decades, the emergence of mature associative geometry modeling tools and the related sophistication in associated manufacturing processes has enabled the design and realization of complex, nonlinear structures. To demonstrate the use of intelligent associative models, the design team developed an iterative method for refining the shell and interior design of surface endoskelet...
