With the growth of the proportion of the ageing population, the problem of population ageing in China has become increasingly prominent because the implementation of family planning policy intensifies the speed of ageing development in China. The restructuring of family structure caused by social reasons, "421" and "422" have become the current family structure mode. With the vigorous development of the economy, the traditional mode and way of the traditional mode and way of providing for the aged cannot meet the spiritual and life needs of the elderly. Most of the institutions only develop the projects to provide for the aged, but not combined with the traditional way of providing for the aged in China. Based on the two-way needs of the young and the elderly, this paper combines the traditional culture with China's current national conditions and constructs the most suitable pension mode for China's traditional pension mode and Chinese people.

As the urbanization process in developing countries continues to accelerate, although my country has achieved significant results in planning and construction, there are still many problems. For example, the rate of urban green space decreases with the continuous increase of urban buildings. Therefore, the domestic urban underground civil air defence Engineering construction is in a very important position at this stage, and our development goals must be shifted from above ground to underground. This article analyzes the general situation of the domestic civil air defence engineering system, expounds on the current situation and existing problems of my country's urban civil air defence engineering system, which has an important influence on the development of my country's cities. Functional departments must take into account the various functions of civil air defence projects and put people's safety first. At the same time, firefighters should also improve their professionalism, leadership and organizational skills, and evacuate people when encountering danger and arrange for them to take refuge in designated locations. The technicians in the relevant departments in the city need to use scientific and technological means to mix the urban network system in series and parallel so that the various structures of the urban network system are unified and interact with each other. When a disaster strikes, it can protect the safety of the people and reduce the economic loss of the city. Reduce to the lowest level to maximize benefits.

In order to provide parameters for sizing a damping reservoir, which was intended to control the floods that occur in the Ipiranga Stream basin, a routine developed in Visual Basic for Applications (VBA) is used. From the identification of the most critical point of the flood, hydrological flow data are presented, estimated by dividing the basin into sub-basins, using the Rational method, resulting in a value of flow higher than the admissible one for the stream channel. The method used in dimensioning the reservoir was flood routing. After making a pre-selection of the most interesting place to position the reservoir, insertions of the situation existent were made to the VBA application, in order to generate scenarios and enable the choice of an ideal situation, in view of the presented constraints. A very acceptable and feasible result is pointed out, indicating general parameters for sizing a reservoir to control floods in the Ipiranga Stream basin.

Pellets are compressed feed, compacted through a mechanical process. Pellets can be molded in the form of lumps and small cylinders with different diameters, lengths, and levels of strength. The right moisture content value will maximize the quality of the pellets and increase the value of the Pellet Durability Index(PDI). Many factors affect the moisture content in the feed such as changing the steam pressure configuration, adding moisture to the mixing process, changing the retention time configuration, and other methods. The method tested was to provide variations on the configuration of retention time and steam pressure on the Pressure Reducing Valve (PRV) which aims to determine the increase in moisture content in the feed. Variations of retention time configuration tested were 50 seconds, 55 seconds, 60 seconds, 65 seconds, 70 seconds with variations in the Steam pressure configuration in the test were 1.4 bar and 1.6 bar. The test results prove that the retention time of 65 seconds with a steam pressure of 1.4 bar is the best configuration with an increase in moisture content of 2.67% with a difference in moisture content of bagging to the mixing of -0.46.
