一 |     8月26日消息，近日，小天才电话手表的健康监测功能引发热议，因一则体重判定结果，遭到网友广泛质疑，同时也引发大众对智能设备健康测评科学性的讨论。    事情源自有网友在社交平台曝光相关截图并发文吐槽。

二 |     A sizable piece of trash discovered in the middle of a sheep pasture in Eastern Australia's New South Wales may be space debris from a SpaceX mission and connected to a loud blast reported in early July in the area, Australian ABC News has reported.,According to the report, numerous people who heard the sound on July 9 turned to social media to report it from as far away as Albury, Wagga Wagga, and Canberra to the Snowy Mountains in southern New South Wales.,An extraordinary nearly three-meter-high object was reported by farmer Mick Miners, who runs a sheep farm at the remote area of Numbla Vale.,"I didn't know what to think, I had no idea what it was," he told the outlet, while his neighbor, Jock Wallace, who also stumbled upon strange debris said he "didn't hear the bang, but my daughters said it was very loud. I think it's a concern it's just fallen out of the sky. If it landed on your house it would make a hell of a mess.",As we all wait for the Chinese booster to impact-Here’s some photos of pieces believed to be from SpaceX’s Crew-1’s Trunk, which landed in Australia on July 9th, but discovered in farmland on July 25thThese are large pieces; which could be dangerous & fatal & more frequent. pic.twitter.com/ImaO4YKQzL— Earth Consuming Mike (@LCS_Big_Mike) July 29, 2022,Serial numbers were seen on one of the items discovered on his premises. Astrophysicist Brad Tucker from the Australian National University College of Science reportedly claimed that the debris was most likely from the craft's unpressurized crew trunk.,SpaceX's Crew Dragon Lifts Off for Its First Operational Mission to ISS16 November 2020, 00:29 GMT,He said that it might be the biggest piece of debris to have been found in Australia since NASA's Skylab space station crashed to Earth above Esperance, Western Australia, in 1979.,"In photographs of the debris you can clearly see charring, which you would expect from re-entry," Tucker told the outlet last Friday. "It is very rare to see, because they don't usually land on land, but in the ocean.",I just got back from Dalgety, NSW. I was busy confirming that parts of a @SpaceX Crew-1 Trunk capsule crashed into a few paddocks in rural NSW!

According to the expert, the craft was probably traveling at 25,000 kilometers per hour when it made re-entry and left behind debris, and it was probably responsible for the July 9 blast heard by many people in the area.,This Monday, in an interview on a local radio, quoted by the Daily Mail, Tucker confirmed that the debris belonged to the Crew-1 SpaceX mission spacecraft.,"This is most definitely space junk which was part of the SpaceX Crew-1 trunk," he is quoted as saying. "SpaceX has this capsule that takes humans into space but there is a bottom part... so when the astronauts come back, they leave the bottom part in space before the capsule lands.",The component, most likely made of aluminum and carbon composites, has been in orbit since November 2020, according to the expert.,"There was a plan of having it come down on Earth and purposely hitting the Earth's atmosphere so it would break apart and land in the ocean," he said.,It took some time to find the object, according to Tucker, because it had fallen far from Miners' house.,"From a distance it looks like a tree almost, like a burnt tree, and then you get closer and you realise 'hey that's not right'," Tucker explained.。截图显示，一名身高167cm、体重50.5kg的青春期女生，被小天才电话手表健康功能判定为“偏重”，系统更是标注该体重“超过99%的同龄女生”。     对此，发帖网友质疑：标准究竟如何界定？片面的判定结果，极易给青春期孩子造成严重的身材焦虑、容貌焦虑，误导青少年对健康体态的认知。    该内容引发网友共鸣，大量网友纷纷表示不解与反对。多数网友认为，167cm、50.5kg的身材属于偏瘦标准，完全不存在偏重、超重情况。无论手表测评的底层算法逻辑如何，直接输出“超过99%同龄女生”的判定结论，缺乏科学依据。    不少网友担忧，这类不严谨的健康判定，会错误引导儿童及青少年，催生不必要的体重焦虑，不利于青少年身心健康成长。

    针对此次争议，有媒体联系到小天才电话手表官方客服进行核实。客服工作人员回应称，手表健康监测中心的身高、体重相关判定数据，由用户手动录入，系统依据BMI数值自动生成测评结果。

四 |     同时，官方表示设备的BMI判定标准参考国家卫生健康委员会卫生行业标准，APP内也已标注对应的参考来源与参考阈值。    后续在媒体表明身份、进一步追问判定合理性后，小天才电话手表官方客服表示该问题需转交相关部门核实，后续将给出正式回复。     值得注意的是，据国家卫健委官方权威资料，BMI即身体质量指数，是目前国际通用的衡量人体胖瘦程度、身体健康状态的核心标准，计算公式为：体重（千克）÷ 身高（米）的平方。    我国针对不同年龄段人群，制定了差异化的BMI健康评价体系，并非采用统一标准：7岁以下儿童采用年龄别BMI标准差法进行健康评价；7至18岁儿童青少年，严格按照性别、年龄对应的BMI界值，开展超重、肥胖专项筛查。    按照官方公式核算，此次争议事件中的女生，BMI数值约为18.1。对照国家卫健委发布的青少年体重管理指导原则来看，9至18岁青春期女生18.1的BMI数值未达到超重、偏重范畴。
