The paper's aim was to further understand the human-computer interaction complexities of past and future advances that have profoundly altered the human development period. After doing a detailed review of many international journals on a similar subject, we decided to take this method. We depend on current data gleaned from Google Scholar searches performed between the years 2-010 and 2021 to resolve this problem. Then we investigate it using a phenomenological approach, beginning with coding, calculation, and interpretation to arrive at precise and reliable final findings. We may infer from the data review that human-computer contact is a sequence of protocols, dialogues, and actions that humans participate in in order to communicate with machines, all of which include input and guidance via a gui in order to obtain the desired outcome.

Abstract Since the reform and opening up, China’s vocational education has experienced a process of gradual recovery and development, which can be divided into five stages: the recovery and establishment period (1978–1984), the simultaneous development period (1985–1990), the sustained development period (1991–1998), the consolidation and adjustment period (1999–2009) and the strategic development period (2010-present). There are some problems, such as low degree of recognition, insufficient degree of adaptation to industrial development, incomplete school management system and lagging teacher team construction. To better cope with the challenges of the new era, we can accelerate the school-enterprise cooperation and industry-education integration, adapt to the changes brought by digital technology to vocational education, improve the management system of vocational education schools, strengthen the construction of vocational education teachers and other ways to promote the high-quality and balanced development of vocational education.

Abstract Capparis micracantha is a Capparaceae family member. Generally, studies on the phenology of this species have not been widely reported. Current research focuses on the chemical composition and its potential as a medicinal plant. Additionally, another interesting phenomenon of C. micracantha is the presence of black ants. This study aims to ascertain the development of flower and fruit formation, as well as the ant-C. micracantha symbiosis. The observation was conducted from January 2017 until January 2020, twice a week at 08.00, 11.00 a.m, and 02.00 p.m., including the development of the branch, leaves, flowers, and fruit. The results indicated that C. micracantha is a shrub with beautiful flowers, both perfect and imperfect flowers. The number of imperfect flowers is approximately 80% greater than the number of perfect flowers. The fruit is round, green when immature, and red fully mature. The development period from bud into ripe fruit was between 90 and 100 days. February-April, June-August, and October-December are the fruiting seasons. The black ants coexist with this plant in a mutualistic symbiosis.

Rebel workers develop from eggs laid by the previous queen, before it went swarming and left the colony orphaned, until the emergence of a new queen. In contrast to normal workers developing in the queen’s presence, rebels are set to reproduce and avoid rearing of successive bee generations. They have more ovarioles in their ovaries, as well as more developed mandibular glands and underdeveloped hypopharyngeal glands, just like the queen. We posited that rebels are not only similar to queens in some anatomical features, but also develop in a shorter time in comparison to normal workers. Therefore, the aim of this study was to compare preimaginal development duration in rebel and normal workers. The results show that rebels, i.e., workers with a higher reproductive potential, had a significantly shorter preimaginal development period (mean ± SD, 19.24 ± 0.07 days) than normal workers (22.29 ± 0.32 days). Our result confirmed that workers who develop in a queen-less colony undergo a shorter preimaginal development than those in a queen-right colony.

The development of a carbon-fiber-reinforced plastic (CFRP) part is carried out by utilizing many experimental results in deciding the design. For this reason, the development period of a CFRP structure is long and an obstacle for commercialization. In this paper, multiple regression analysis is used to derive a response surface that estimates the generated load using the shape parameters of a corrugated collision energy absorbing structure to shorten the development period. To obtain the response surface, we conducted a quasistatic crushing experiment by using the length of linear portions (pitch) and the number of stacks (thickness) of a corrugated shape as parameters. When progressive crushing mode is observed, energy absorption efficiency decreases with the increase in pitch, and increases with the increase in the number of stacks. To discuss how energy absorption efficiency changes, a comparison examination is conducted using the derived response surfaces. Results indicate that specifications with high energy absorption efficiency can be accurately selected using the response surface of primary expression. In addition, differences in deformation mode were due to the influence of the stress at the corner portion of a part.

According to the period development and the typical characteristics of medical stages, traditional medicine can be divided into six aspects: legendary traditional medicine, instinctive traditional medicine, witchcraft traditional medicine, empirical traditional medicine, theoretical traditional medicine and integrated traditional medicine. Among them, instinctive traditional medicine and legendary traditional medicine belong to the stage of ignorance according to the level of human cognition (“not knowing reason and result”, “only knowing result” and “knowing reason and result”). It belongs to the immature and hazy development period of human traditional medicine before it became “medicine” from the perspective of the development of traditional medicine, which can be summarized as the pre-medical period. Scientific understanding of traditional medicine and instinctive traditional medicine is helpful for people to understand and grasp the development of traditional medicine and even the whole medicine.

The 2019–20 Australian bushfire produced strong plumes that carried massive quantities of gases and aerosols through the tropopause into the stratosphere. The 2019 El Niño and a rare sudden stratospheric warming (SSW) in the Southern Hemisphere (SH) that occurred in austral spring 2019 caused reduced precipitation in eastern Australia, which caused the strongest bushfire in history in terms of area and disaster degree. High-intensity bushfires triggered chemical reactions, including the rapid secondary formation of formic acid (FA). The strong intensity of the bushfire and the isolated environment allowed their impacts to be well detected. We identified the most active bushfire period (December 30–January 1) and its impacts on atmospheric components. The trajectory and lifetime of bushfire plumes were analysed to reveal the bushfire process and most active period. Based on multiple satellite and reanalysis products, unique variations in atmospheric components were identified and attributed to three main factors: bushfire development period, stratospheric heating mechanism and rapid secondary formation of FA. The bushfire gradually increased in intensity from June, reached its most active period from December 30–January 1, and then weakened. The bushfire development period caused delays in the plumes and peak values of gases (CO, SO2, FA and ozone) and temperature. The diurnal cycle, particle concentration and time restricted the total radiative forcing of aerosols and gases, which prevented a high rate of temperature increase similar to that of gas input from plumes. The strong intensity of the bushfire caused rapid secondary formation of FA, which caused a sharp increase in FA production from December 30–January 1.
