The aim of our study was to recognize different skin conditions of the face and neck using six biophysical parameters and to show the changes after the application of ultrasonic stimulation (US). We assessed the differences in the sebum, moisture, pores, wrinkles, pigmentation, and elasticity of the skin in the face and neck regions. A total of 30 healthy men in their 20s were enrolled. We used a skin diagnosis meter to assess the state of the skin. The sebum and pores of the face were more significant than in the neck. The amount of moisture in the U-zone was significantly higher than in other areas. Statistical differences were found between the pre-and post-measure-ment values in the sebum, moisture, wrinkles and pigmentation. Wrinkles and pigmentation were positively correlated. Our data showed that the changes in skin condition are associated with external stimulants. The effect of US on skin may differ depending on the part of the body, and some biophysical properties of skin vary depending on the location on the body.

Studies have demonstrated that some cutaneous biophysical properties vary with the part of the body. The results to date of skin conditions in human skin of multiple parts of the body have not yet been well established. In this study, we assessed the differences in the skin’s sebum, moisture, pores, wrinkles, pigmentation, and elasticity of each body part in Korean men in their 20s. A total of 34 healthy men were enrolled. A Skin Diagnosis Meter was used to measure the skin’s surface sebum, moisture, pores, wrinkles, pigmentation, and elasticity of each body part. The sebum content was significantly higher on the face than at other sites. Moisture was significantly high on the feet. Pores were significantly high on the face. Wrinkles were significantly high on the face. Pigmentation was high on the face and neck, but not significantly. Elasticity was significantly high on the hands. In the correlation analysis results, sebum and pore were positively correlated, but sebum and moisture and wrinkle and elasticity were negatively correlated. For nearly the first time, this study resulted in systematic reference values for standardized biophysical measuring methods and body parts reflecting the skin physiology of healthy South Korean men. The results show that skin’s surface sebum, moisture, pores, wrinkles, pigmentation, and elasticity vary with the part of the body.

We examined the changes in numerous skin conditions before and after the ap-plication of interferential current therapy to various regions of healthy male bodies. In this study, we assessed the differences in the skin’s sebum, moisture levels, pores, wrinkles, pigmentation, and elasticity on the shoulders, lower back, and the knees of Korean males in their 20s. A total of 30 healthy males were in-cluded in the study. We used a skin diagnosis meter as a device for measuring the state of the skin. A statistical difference was found when comparing the pre- and post-measurement values in regards to the moisture levels, wrinkles, and pig-mentation. In the correlation analysis results, the sebum and pigmentation, moisture levels and wrinkles, moisture levels and pigmentation, and moisture levels and elasticity were all positively correlated, respectively. The results of this study partially suggest that a change in skin condition is associated with ex-ternal stimulation. The study also found that the effects of the application of in-terferential current therapy on the various skin conditions may differ depending on the region of the body that the application is conducted as well.

众包服务已成为各个领域的主流服务计算范式。在众包服务中,如何选择合适的移动用户形成团队并用于众包服务是一个挑战性的问题。目前大多数研究都集中在使通信成本最小化的团队组建方法上,但在众包服务实际应用中,存在不基于沟通成本最小化的团队组建问题;因此,文章在社交网络框架下提出了基于公平性最大化的团队组建方法,给出了基于公平性最大化的团队组建方案和任务众包算法,并在实际社交网络中验证了基于公平性最大化的团队组建方案和任务众包算法。其结果表明,所提出的基于公平性最大化的团队组建方法是有效的,并在众包服务中具有实际应用价值。
