Then, based on the causes, eight measures to improve goods purchasing management were put forward, and graphs were used to illustrate the corresponding countermeasure to each cause. This study is of theo- retical significance for the food processing enterprises to improve the quality man- agement of purchased goods through formulating improvement measures based on their operating states.展开更多

It was evaluated as the 2nd class of fine quality rice variety in Hunan Province in 2012. It is characteristic of high-yielding ability, fine grain quality, good plant type, good lodging resistance and fertilizer tolerance, strong tillering ability and good discoloring at the late growth stage. Taoyou Xiangzhan was registered for release to commercial production by Hunan Provincial Crop Variety Appraisal Committee in June, 2015.展开更多

It is indica hybrid dce. It is good in quality and has upright leaves, thick stalks, good resistance to lodging, and strong cold resistance. It participated in the regional test of hybrid indica rice varieties in Yunnan Province from 2007 to 2008 and was approved by the Crop Variety Ap- proval Committee of Yunnan Province (Dianshendao No. 2009021).展开更多

As always said, that young Gulf inherently consumerist element of first degree because of abundant liquidity and reasonable level of income compared to others of non - Gulf societies. Therefore, this research aims to study and analyze the impact of consumer awareness among the students of the Faculty of Business Administration in consumer protection in terms of the current role and hoped to guide consumption and its relationship to some economic and social characteristics of the consumers. In particular it has been studying the impact of some of the qualifications for heads of Kuwaiti families, their total monthly income and their place of residency inhabited by the expressive factors of consumer awareness in college students as well as their impact on the degree of preference for quality of consumer goods in being a low-price, median-price or expensive-price. In addition, it has been studying the relationship of these social variables noted with the role of government and consumer protection associations through what they are doing to develop laws and policies directed to develop and educate consumers. To achieve these goals, a special questionnaire has been prepared especially for this purpose has been met from a random sample of students from the University of Kuwait. I have been using the appropriate statistical analysis to study these goals. Thus, some of the appropriate suggestions and recommendations are obtained to achieve the objectives of this research.展开更多
