今天星期天将以前开发的项目整理一下，希望跟大家一起共同学习

在前台的功能实现上，可以分为以下几个部分：
1.教师饮食管理：根据教师的相关信息，计算其每天所需热量，给出一周的推荐菜单。
2.教师健康日志：用户可以记录自己健康日记，记录每一天的睡眠，饮酒，吸烟，血压，体重等情况。
3.教师体检管理：教师可通过该平台查询每次的体检结果，显示部分项目随时间变化的曲线。
4.疾病预测评估：针对糖尿病和高血压两种疾病，利用数学线性回归的方法，模拟计算出教师患病概率。

代码已经上传github，下载地址：https://github.com/21503882/community-manage
2.2.2 后台功能
后台主要有四个功能：
1．管理员用户登录功能：通过编号登录系统。
2．管理员管理教师功能：可以增删改查教师基本信息。
3．管理员管理体检结果：可以增删改查教师体检记录。
4．管理员管理健康新闻：可以发布或删除新闻。
