Early in the communist era, many cities in modern China experienced a special period of passive industrialization during which the construction of urban spaces laid the spatial urban foundation. During this period, the city construction was carried out rapidly under the administrative intervention of the government. The passive industrialization caused by taking economic construction as the center made the city construction deviate from the correct track and resulted in a variety of problems. Focusing on ecological space change, this paper selects Zhengzhou as an example of many similar cities in China, and analyzes the impact of passive industrialization on urban ecological spaces from the perspectives of city scale, city layout and city construction management system. The analysis results reveal that the construction of urban ecological space under the influence of passive industrialization induced a lagging characteristic, led to insufficient integrity of urban ecological space, and placed great pressure on the urban environment. Finally, the paper puts forward some methods to optimize the urban ecological space.

With the acceleration of construction industrialization, the buildings that China has adopted the construction of industrialization technology are increasing day by day, and Precast Concrete (PC) Structure technology is one of the main technologies of construction industrialization. Compared with the traditional cast-in-place concrete structure, PC structure is more conducive to shorten the construction period, reduce the number of construction workers and the site construction waste. Nevertheless, PC structure improves the requirements of hoisting machinery in the construction site, and the lay-out and selection of hoisting machinery become an important factor influencing the construction cost. The paper regards the typical tower crane in China as the research object, and establishes the time optimization model for the lifting scheme. The influence of the different precast rate on the selection of the tower crane is analyzed. This paper obtains the time variation of the tower crane under different precast rate, provides a theoretical basis for the design of precast concrete structures under the influence of assembly construction, and lays the foundation for the selection of tower crane under the precast rate.

In the modem society of Japan, specially before and after the World War II, one of the most important problem is socially to build housing of working classes. In those days, Ken Ichiura had been led the dwelling of modem Japanese architecture. He had worked in wide spheres of action like private residence, public housing, collective housing area and urban planning for about fifty years. But until now, because studies on public housing of Japan has been discussed only aspect of architectural design, there was almost no study about Ken Ichiura who acted in practical affairs. So this study aims to consider about the Ken Ichiura's research on dwelling and the relation with the then social circumstance. It was summarized as four details of Ken Ichiura's activities on Dwellings before the end of World War II. First, he proposed half-government-supervised system by economic reason on provision of dwellings. Second, he proposed dry construction system by material and structural reason on economic and stability supply. Third, he proposed standardization and industrialization by economic reason on industrialization form material to construction of industry. And the last, he also proposed standard plan and standard design by economical and mass production supply dwellings during the war.

The concept of Eco-city is to protect the city against development, trash, and industrialization. But the sprawl phenomenon of urbanization and industrialization are accompanied by the environment destruction. Therefore the importance and definition of eco-city were suggested. And to restore the urban ecological network, the prototype direction of eco-city at YongJeonDong in DaejeonCity were suggested in this study. It is believed that how to create an eco-city is an artificially developed $\square\square$Yong-Jun Dong$\square\square$ is a pending issue we are faced with situation. Herein lies the necessity of natural environment restoration and creation based on the so-called the Third Ecology

Recently, particulate matter(PM) caused by internal factors such as industrialization and urbanization as well as external factors such as Asian dust is a serious problem in Korea. In particular, while the emission due to construction appears to be very serious among the internal factors, it is necessary to manage PM in consideration of the characteristics of construction sites. Accordingly, in this study, a PM management system suitable for construction sites was developed to reduce civil complaints caused by PM and to minimize damage to field workers and nearby residents by supporting the fine dust management system of the state and local governments. The factors to be considered when measuring PM due to the specificity of construction sites were considered, and the system components were developed based on the considerations. As a result, an IoT based construction site PM monitoring system (CPMS) that integrates each component was established.

Precast concrete apartments were main stream of domestic industrialized housing around 90's, and Steel Houses applying Steel Stud technique with light weighted steel have been dominant portion since 1995. On the other hand, various building techniques including Steel Stud method and highly prefabricated and industrialized Unit method are prevailing in developed countries like Japan. Steel stud and unit box have their own merits and demerits, but the more crucial aspect is that the constant design standard should be applied in each design procedure. It entails the necessity of industrial housing development on the open system basis. In this study, the design standard for unit house will be established coping with the established preparing standard for design specifications defined by architectural law and promotion law of housing construction. That is for design standard of industrialized private housing on the open system basis. This study attempts to propose the design automation, with the method of unit construction of which the rate of pre-fabrication is the biggest, that can cope with the demand of user on the basis of open-system. Ticky-tacky is the biggest technical problem in suppling industrialization housing. Therefore, we will suggest a basic plan for design automation of unit modular housing which can raise the productivity of industrialization housing by applying open system, utilized by DB of component and unit, and solve the problem concerned about ticky-tacky.
