Sexual dysfunction (SD) is a health problem which occurs during any phase of the sexual response cycle that keeps the individual or couple from experiencing satisfaction from the sexual activity. SD covers a wide variety of symptoms like in men, erectile dysfunction and premature or delayed ejaculation, in women, spasms of the vagina and pain with sexual intercourse, in both sexes, sexual desire and response. And pharmacopuncture, i.e. injection of subclinical doses of drugs, mostly herb medicine, in acupoints, has been adopted with successful results. This case report showed the effect of bee venom on SD. A 51-year-old male patient with SD, who had a past history of taking Western medication to treat his SD and who had previously undergone surgery on his lower back due to a herniated disc, received treatments using pharmacopuncture of sweet bee venom (SBV) at Gwanwon (CV4), Hoeeum (CV1), Sinsu (BL23), and Gihaesu (BL24) for 20 days. Objectively, the patient showed improvement on most items on the International Index for Erectile Dysfunction (IIEF) like 28 to 29 out of perfect score 30 for erectile function, 10 to 10 out of perfect score 10 for orgasmic function, 6 to 8 out of perfect score 10 for sexual desire, 10 to 13 out of perfect score 15 for satisfaction with intercourse, and 6 to 8 out of perfect score 10 for overall satisfaction; subjectively, his words, the tone of his voice and the look of confidence in his eyes all indicated improvement. Among the variety of effects of SBV pharmacopuncture, urogenital problems such as SD may be health problems that pharmacopuncture can treat effectively.

In recently, a growing concern for the health of urban residents increased interests in a variety of outdoor activities simply be done in terms of cost and time. They are specially interested in low-impact and safe exercises around residential or working area. Walking is the one of easily doing exercise in daytime or nighttime near residential area. The sidewalks of boulevard near the residential area is the best place for exercise because of easy access and the green space with roadside trees. However, if the nighttime is not guaranteed the proper lighting condition, the possibility of exposure to crime and the threat to pedestrian safety can be increased. Because roadside trees are one of the potential obstacle for lighting condition, supplementary lightings are important to mitigate interruption for safety. To meet such a need, the purpose of this study is to propose a simulation approach which improves lighting condition on sidewalks of boulevard with variety of roadside trees. To do so, the simulation approach is applied for analyzing the interrupted condition by classified five standard types of roadside trees considering the growth of them and finding optimal layout of supplementary luminaires by lighting types. The results of this approach shows that it is useful for assessing the safety of pedestrian in nighttime.

Single-walled carbon nanotubes (SWCNTs) have attracted much attention as promising materials for transparent conducting films (TCFs), thanks to their superior electrical conductivity, high mechanical strength, and complete flexibility. The CNT-based TCFs can be used in a variety of application fields as flexible, transparent electrodes, including touch panel screens, flexible electronics, transparent heaters, etc. First of all, this study investigated the effect of a variety of surfactants on the dispersion of SWCNTs in an aqueous solution. Following the optimization of the dispersion by surfactants, flexible TCFs were fabricated by spraying the CNT suspension onto poly(ethylene terephthalate) (PET) substrates. The sheet resistances of the TCFs having different surfactants were investigated with treatment in nitric acid ($HNO_3$) whose concentration and period of treatment time were varied. It seems that the $HNO_3$ removes the surfactants from and is simultaneously doped into the SWCNT network, reducing the contact resistance between CNTs. TCFs were characterized by UV-VIS spectroscopy, thermogravimetric analyzer (TGA), scanning electron microscopy (SEM), and four-point probe.
