Edge computing is an innovation of network architecture and business model for operators.5G edge computing node is composed of 5G UPF and edge computing platform.It can be deployed at different levels of the network based on the demand for bandwidth,delay and local streaming.In the perspective of 5G application scenarios,depending on edge computing can meet the customer needs of differentiated vertical industries and seize the market opportunities,which is a sharp tool for operators to enter the vertical industry.The business model,billing scheme,landing deployment strategy and scheme of edge computing deployment were mainly studied,including business scenario,infrastructure,hardware system,site selection methodology,construction scheme,peripheral networking scheme,etc.

In order to adapt to the needs of rapid deployment and convenient configuration in 5G emergency communication scene, the terminal, base station, user plane function(UPF), mobile edge computing(MEC), core control and other network devices must be simple, efficient and flexible. In order to quickly build emergency communication private network application scenario, this paper puts forward a scheme of integrated edge fusion technology and equipment implementation，which provides a highly integrated wireless access，data forwarding and edge application service ability for 5G field emergency communication，at the same time, also simplifies the complexity of equipment operations and external network requirements, and improves the service performance of the whole system.

UV protection pantyhose are in the market, but the effectiveness of the ultraviolet radiation (UV) protection on these stretchy products while being worn was not yet to be clarified. The purpose of this study is to examine the UV protection efficiency on items made of stretchy fabric, namely the pantyhose and tights, while being worn. Samples correlating to items being worn were fitted on the mannequin legs to monitor the transmittance, UPF, and porosity on the three parts of the body: the ankle, the calf, and the thigh. It was found that the UV protection efficiency of pantyhose and tights that stretch when worn was greatly influenced by porosity, and that the UV protection efficiency decreased as porosity increased. The fine yarn of pantyhose with high porosity did not possess any UV protection efficiency, and the UV protection was found useless. In case of tights, it was clarified that items with higher porosity were influenced by lightness rather than hue, and the lower the lightness, the higher the UV protection efficiency. Black color indicated adequate UV protection efficiency when porosity was less than 10%. UV protection efficiency of tights showed correlation with weight, but not with denier.

Four M-type reactive dyes (yellow, orange, red and blue) containing a built-in 2-(2-hydroxy-5-sulfophenyl)-5-amino-2H-benzotriazol group were synthesized using p-ester and sulphonated p-ester as diazo component, and their structures were identified by MS. Cotton fabrics were dyed with prepared dyes, the reactivity degree and exhaustion degree of dyes were measured, and the dyeing property of yellow dye was worse. Compared with the undyed cotton fabric, the UV transmittance of dyed fabrics has a great decrease. The UPF values of undyed cotton fabric is 1. 3, and cotton fabrics dyed with yellow, orange, red and blue dyes are 5.9, 13.7, 18.8, 17.5 respectively, which show good anti-UV properties except yellow dyes. It is also found that the anti-UV property of dark fabrics is better than that of light fabrics. [ABSTRACT FROM AUTHOR]
