The interview was meant in part to celebrate the tenth anniversary of the implementation of the Labor Law of the People's Republic of China that falls on January 1,2005. We are publishing this transcript with a view to providing our readers with information about how China has worked persistently to protect citizens' right to work and social security and the achievements it has made in this regard. We need to remind our readers of the fact that back in March 2004, the National People's Congress, China's highest legislature, approved a recommendation for revision of China's Constitution. In accordance with the recommendation, the Constitution had one more clause added: The state shall establish and improve a social security system commensurate to the level of the economic and social development.展开更多

The results show that there is a long-term co-integration relationship between population aging and social security expenditure in the demographic structure, and there is a positive correlation between population aging and social security expenditure. And the different cross-sectional effects in 31 regions of China reflect the difference between population aging and social security expenditure in different regions of China.展开更多

If the emergencies are not under control, the crisis will get worse and its destructive energy will be released quickly.Structure box is an invisible closed system which is constructed by local politics, economy, and culture. Namely, structure box is local social ecological environment. Structure box is a closed area which is full of anger. Therefore, in such environment with too much pressure, we need an outlet to release pressure. Anger is the social and psychological basis of the emotional resonance of onlooker, when the fuse incident occurred, so that the widespread anger in structure box will find the spotlight. The words and actions of the leaders in the informal group will produce a great social infection and circulatory response, and groups’ stirring will cause emotional resonance which is easy to burst. Thus, irrational behavior may caused by people. This processcan use five links to describe： occurrence of fuse events, information diffusion, emotional resonance, situational catalysis, control failure, and occurrence of public security emergency. This is the occurrence mechanism of public security emergency.展开更多

In this article,the existing middleware technologies was analyzed,the problem-solution approach of heterogeneous data sharing was discussed through middleware technologies. Based on this method,and according to the characteristics of early warning system for grain security,the technology of data sharing in this system were researched and explored to solve the issues of collection of heterogeneous data sharing.展开更多
目的:观察比较腋窝皱襞切口薄皮瓣法及小切口全厚皮片法用于腋臭治疗的疗效。方法:选取2016年11月-2021年11月笔者医院行腋臭手术治疗的78例患者,依据手术方式不同分为观察组和对照组,每组39例。观察组行腋窝皱襞切口薄皮瓣法,对照组行...目的:观察比较腋窝皱襞切口薄皮瓣法及小切口全厚皮片法用于腋臭治疗的疗效。方法:选取2016年11月-2021年11月笔者医院行腋臭手术治疗的78例患者,依据手术方式不同分为观察组和对照组,每组39例。观察组行腋窝皱襞切口薄皮瓣法,对照组行小切口全厚皮片法。比较两组患者临床疗效、围术期各项指标、温哥华瘢痕量表(Vancouver scar scale,VSS)评分、患者与观察者瘢痕评估量表(Scar assessment scale for patients and observers,POSAS)评分及并发症发生情况。结果:观察组总有效率高于对照组,复发率低于对照组,手术时间、拆线时间、愈合时间均短于对照组,出血量少于对照组,瘢痕长度短于对照组,并发症总发生率低于对照组,差异均有统计学意义(P<0.05);术后6个月,观察组VSS、PSAS、OSAS评分均低于对照组(P<0.05)。结论:腋窝皱襞切口薄皮瓣法治疗腋臭疗效优于小切口全厚皮片法,该法复发率低,瘢痕轻,并发症少,是治疗腋臭较为理想的一种术式。展开更多
