Home-Based Intelligent Exercise System for Seniors' Healthcare: The Example of Golf Croquet.

In 2020, the world experienced the threat of the COVID-19 epidemic, and seniors and chronic disease patients generally reduced their exercise and social activities to avoid increasing the risk of infection, which could lead to increased loneliness and even many diseases. Combining golf croquet games with a mobile application (App) and AIoT companion robots, this research constructs a home-based intelligent exercise system, uses the technology acceptance model (TAM), deduces users' intention to use this system based on perceived usefulness and perceived ease of use, and adds the needs of love and belonging, esteem, cognitive, aesthetic, and self-actualization in Maslow's hierarchy of needs theory (HNT) to conduct an analysis of system needs. This study collected empirical data, totaling 320 participants including seniors and their caregivers, from elderly care centers in northern Taiwan using a cross-sectional survey and purposive sampling.

[Adventitious Buds Induction of Mentha haplocalyx Under Variation Inducted by NaN3].

Objective: To establish the chemical mutagenesis in vitro system of Mentha haplocalyx,the effects of different plant hormone combination and Vc on the induction of mint stem adventitious buds and the mutation effects of different concentrations of NaN3 on their calli were studied.

Methods: The internodes of mint used as the material,and based on the preliminary experiment, the effects of different concentrations of TDZ,6-BA,NAA and Vc on adventitious buds induction rate were researched. On the basis of screening the best induction formula, the Mentha haplocalyx calli were treated with different concentrations of NaN3（ 0,2,4,6,8,10,12,14,16 mg/L）.

[Effects of high temperature and humidity stress at the physiological maturity stage on seed vigor, main nutrients and coat structure of spring soybean].

A pot experiment was conducted to investigate the effects of high temperature and humidity stress [(40 +/- 2) degrees C/(30 +/- 2) degrees C, RH (95 +/- 5)%/(70 +/- 5)%, 10 h/14 h (day/night)] at the physiological maturity stage of two spring soybean cultivars (Xiangdou No. 3 and Ningzhen No. 1) on seed vigor indices, main nutritional components and coat anatomical structure.
