<P>An all‐solution‐processed flexible piezoelectric nanogenerator, composed of polycrystalline ZnO thin film and functional polymer layers such as P3HT/PCBM and PEDOT:PSS, generates energy through a mechanical rolling and muscle stretching system. On page 6022, Youn Sang Kim, Sang‐Woo Kim, and co‐workers show that this all‐solution‐processed nanogenerator is feasible as a piezoelectric patchable device and is promising for use in future energy harvesters such as wearable human patches and mobile electronics. </P>

<P>The mean color of globular clusters (GCs) in early-type galaxies is in general bluer than the integrated color of halo field stars in host galaxies. Metal-rich GCs often appear more associated with field stars than metal-poor GCs, yet show bluer colors than their host galaxy light. Motivated by the discovery of multiple stellar populations in Milky Way GCs, we present a new scenario in which the presence of second-generation (SG) stars in GCs is responsible for the color discrepancy between metal-rich GCs and field stars. The model assumes that the SG populations have an enhanced helium abundance as evidenced by observations, and it gives a good explanation of the bluer optical colors of metal-rich GCs than field stars as well as strong Balmer lines and blue UV colors of metal-rich GCs. Ours may be complementary to the recent scenario suggesting the difference in stellar mass functions (MFs) as an origin for the GC-to-star color offset. A quantitative comparison is given between the SG and MF models.</P>

<P><B>Purpose</B></P><P>Few studies have addressed gonadal and sexual dysfunctions in childhood cancer survivors. We evaluated the prevalence rates and risk factors for gonadal failure among adolescent/young adult childhood cancer survivors and their sexual function.</P><P><B>Materials and Methods</B></P><P>Subjects were childhood cancer survivors aged 15-29 years who had completed therapy more than 2 years ago. Demographic and medical characteristics were obtained from the patients’ medical records. In addition, hormonal evaluation and semen analysis were performed and sexual function was evaluated via questionnaire.</P><P><B>Results</B></P><P>The study included 105 survivors (57 males, 48 females), of which 61 were adults (age > 19 years) and 44 were adolescents. In both males and females, the proportion of survivors with low sex hormone levels did not differ among age groups or follow-up period. Thirteen female subjects (27.1%) needed sex hormone replacement, while five males subjects (8.8%) were suspected of having hypogonadism, but none were receiving sex hormone replacement. Of 27 semen samples, 14 showed azospermia or oligospermia. The proportion of normospermia was lower in the high cyclophosphamide equivalent dose (CED) group (CED ≥ 8,000 mg/m<SUP>2</SUP>) than the low CED group (27.3% vs. 62.5%, p=0.047). Among adults, none were married and only 10 men (35.7%) and eight women (34.3%) were in a romantic relationship. Though a significant proportion (12.0% of males and 5.3% of females) of adolescent survivors had experienced sexual activity, 13.6% had not experienced sex education.</P><P><B>Conclusion</B></P><P>The childhood cancer survivors in this study showed a high prevalence of gonadal/sexual dysfunction; accordingly, proper strategies are needed to manage these complications.</P>
