Purpose: The purpose of this study was to examine university male students’ exposure to internet pornography, and its influence on sexual violence awareness status and sexual attitude to provide educational materials. Methods: Data were collected through self-reported questionnaires from 286 male students who are attending universities in Seoul and Gyunggi-Do from August 20th to October 16th in 2017. 81 questionnaires in total were analyzed using mean, S.D, t-test, ANOVA, Scheffe with SPSS 22.0. Result: The results summarized according to research subject matter are as follows. First, most of the participants watched pornography 1-2 times per week(36.0%), 20mins-30mins(57.0%), heterosexual intercourse(92.0%) by cell phone(52.4%). Second, general characteristics of male university students’ influenced by sexual violence awareness status and sexual attitude showed significant difference in 4 factors of sexual attitude according to general characteristics of male university students in order of ‘chastity’, ‘homosexuality’, ‘contraception’, and ‘sexual consciousness’. Third, the influence of male university students’ internet pornography exposures on sexual awareness and sexual attitude showed significant difference in sexual awareness according to ‘change in sexual behavior after watching pornography’. There was significant difference in 3 factors of sexual attitude according to exposure of university male students to internet pornography. Conclusion: This study suggest that sexual education development for male university students is needed in order to establish upright sexual values that can lead to healthy sexual behaviors.

Although many facets of gynecomastia are enigmatic, the histopathologic features have been defined by several authors who have based their observation on surgically resected breasts. A histopathologic study was made on fifteen cases of gynecomastia that were observed during past five years, 1960 to 1964, at department of pathology, college of medicine, Seoul National University. It has been shown that varying degree of duct hyperplasia associated with concentric periductal fibrous tissue proliferation was the most conspicuous features of gynecomastia. Varying degree of proliferation, elongation or branching of mammary ducts were noted and the inflammatory cell infiltration predominated by lymphocytes and plasma cell was not infrequent. However, not a single case revealed formation of acini or lobules simulating female breast. The lesions were unilateral in all cases and no systemic endocrinopathy was encountered clinically.

<P>Rational design of efficient and durable bifunctional oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) electrocatalysts is critical for rechargeable metal–air batteries. Here, we developed a facile strategy for fabricating three-dimensional phosphorus and sulfur codoped carbon nitride sponges sandwiched with carbon nanocrystals (P,S-CNS). These materials exhibited high surface area and superior ORR and OER bifunctional catalytic activities than those of Pt/C and RuO<SUB>2</SUB>, respectively, concerning its limiting current density and onset potential. Further, we tested the suitability and durability of P,S-CNS as the oxygen cathode for primary and rechargeable Zn–air batteries. The resulting primary Zn–air battery exhibited a high open-circuit voltage of 1.51 V, a high discharge peak power density of 198 mW cm<SUP>–2</SUP>, a specific capacity of 830 mA h g<SUP>–1</SUP>, and better durability for 210 h after mechanical recharging. An extraordinary small charge–discharge voltage polarization (∼0.80 V at 25 mA cm<SUP>–2</SUP>), superior reversibility, and stability exceeding prolonged charge–discharge cycles have been attained in rechargeable Zn–air batteries with a three-electrode system. The origin of the electrocatalytic activity of P,S-CNS was elucidated by density functional theory analysis for both oxygen reactions. This work stimulates an innovative prospect for the enrichment of rechargeable Zn–air battery viable for commercial applications such as armamentaria, smart electronics, and electric vehicles.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/ancac3/2017/ancac3.2017.11.issue-1/acsnano.6b05914/production/images/medium/nn-2016-05914q_0007.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nn6b05914'>ACS Electronic Supporting Info</A></P>

A 27-year-old male was suffered from seizure due to Galenic aneurysmal malformation which was mainly fed by thalamoperforating circumferential(P2) and posterior cerebral artery(P4) and drained through basal vein of Rosenthal because of agenesis of straight sinus. The aneurysmal dilatation was successfully extirpated by excision of feeding arteries and draining veins including inferior sagittal sinus and straight sinus. We report a case of true aneurysmal malformation of vein of Galen.

<P><B>Abstract</B></P><P>A gel electrolyte based on polyurethane as a polymer matrix was prepared by the UV curing of a liquid electrolyte containing an aliphatic urethane acrylate. By controlling the concentration of the polymer matrix, the ionic conductivities of the gel electrolytes were varied from 9.8 × 10<SUP>−3</SUP> S/cm to 4.7 × 10<SUP>−3</SUP> S/cm at room temperature. The quasi-solid state dye-sensitized solar cell (DSSC) fabricated with the gel electrolyte rendered an overall energy conversion efficiency of 6.1% under irradiation of 100 mW/cm<SUP>2</SUP> at room temperature. The DSSC employing the gel electrolyte showed better photovoltaic performance than the DSSC assembled without the polyurethane at temperatures above 55 °C.</P> <P><B>Graphical abstract</B></P><P><ce:figure id='dfig1'></ce:figure></P><P><B>Highlights</B></P><P>► Polyurethane based gel electrolyte for a dye sensitized solar cell. ► Gel electrolyte for the improvement of high temperature stability. ► The DSSC employing the gel electrolyte showed better PV performance than that employing liquid electrolyte above 55 °C.</P>
