Kadir Has University building has been selected as the case study of the research. Success of the conversion and interventions in terms of sustainability will be discussed. The aim of the study is to question adaptive reuse project of the Cibali Tobacco Factory as university within the framework of urban regeneration of Cibali district. The relation between adaptive reuse projects and its relationship among socio-cultural, economic, and physical dimensions of the sustainability, also its effects on the environment and region has been discussed. Adaptive reuse examples should not be accepted as single projects. Its contribution to the environment and the region is also crucial. Preservation of an individual building can be a catalyst to renewal of others. It can help the transformation of the whole area. There is always an interaction between the conversion projects and the environment. In order to achieve a successful conversion, appropriate functions should be given to the industrial heritage buildings according to the needs of the region.展开更多

Trend books from Milan and Paris have been introduced to big cities in China through official Chinese national agencies, and have gradually drawn more attention within the Chinese fashion industry. Chinese fashion businesses and their designers have difficulties in using the trend book. The main reason is that they don’t understand the whole structure re of the book, the true meaning of the instruction and the way to use the book. Most companies are not using the book in the correct way. However, if no one realizes this is not the right key to the real fashion design world, an incorrect design logic and abnormal production chain will appear in China which will directly produce an unhealthy impact to the country. It’s only possible to catch up and grasp the real European trend with Europe at the same time when the trend books are used correctly.展开更多

Attracting the majority of enterprises, Wechat increasingly become a new product marketing platform. Wechat marketing in the film industry has also been widely used. but the development of the film industry has its own characteristics, so when using Wechat marketing, certain principles and methods should be followed, to achieve the desired effect. This paper focuses on the analysis of film industy marketing based on Wechat platform and also predicting its development trend.展开更多

In this problem, each job has three operations. The first and last operations are performed by the same primary machine, implying the reentrance, and the second operation is processed on the single server machine. The order of jobs is predetermined in our context. The challenge is to assign jobs to the primary machines to minimize the makespan. We develop a genetic algorithm(GA) to solve this problem. Based on a simple strategy of assigning jobs in batches on the parallel primary machines, the standardized random key vector representation is employed to split the jobs into batches. Comparisons among the proposed algorithm, the branch and bound(BB) algorithm and the heuristic algorithm, coordinated scheduling(CS), which is only one heuristic algorithm to solve this problem in the literature, are made on the benchmark data. The computational experiments show that the proposed genetic algorithm outperforms the heuristic CS and the maximum relative improvement rate in the makespan is 1.66%.展开更多

The deterioration of the air quality affects more and more the population's health with significant cost and damage to the community, this study aims to quantify the degree of aerosols pollution damage and also its health effects.展开更多
