Career development for women in maritime industry: organisation and socialisation perspectives

For centuries, the maritime industry has been a recognised place in society dominated solely by men, and even though there were women involved, they were mostly on the periphery. This research aims to fill the gap of women’s career development in this field, by investigating the relationships among the degree of organisational socialisation, women’s workplace culture, and the career development of women in the maritime workplace. The analyses are conducted with the structural equation model with 202 valid questionnaires. The results indicated that women’s workplace culture has a significantly negative relationship with the degree of organisational socialisation, and then in turn, it has a significantly positive relationship with women’s career development in the maritime industry. Finally, the results also indicate that the mediating effect of organisational socialisation existed between women’s workplace culture and women’s career development. According to the empirical analysis, this study makes conclusions as well as suggestions for the maritime enterprises as the reference for human resource management.

基于硬化泥膜的填舱换刀技术研究

为了解决砂土地层盾构刀盘换刀作业面易涌水、涌砂进而导致作业面失稳坍塌问题,采用水泥砂浆和膨润土浆液组成的混合浆液在土舱压力作用下,通过刀盘开口向砂土地层渗透,经固化后在原有稳定泥膜的基础上形成新型混合泥膜,在利用风镐清除土舱内硬化混合浆液的同时,保留刀盘前段形成的混合泥膜,即可进行盾构刀盘换刀作业。通过在广州某地铁盾构施工项目中的应用,表明本施工技术能为砂土地层盾构换刀提供高效且安全的解决方案。

A data model applied to the knowledge-based ICAS

Image-guided computer aided surgery system (ICAS) contributes to safeness and success of surgery operations by means of displaying anatomical structures and showing correlative information to surgeons in the process of operation. Based on analysis of requirements for ICAS, a new concept of clinical knowledge-based ICAS was proposed. Designing a reasonable data structure model is essential for realizing this new concept. The traditional data structure is limited in expressing and reusing the clinical knowledge such as locating an anatomical object, topological relations of anatomical objects and correlative clinical attributes. A data structure model called mixed adjacency lists by octree-path-chain (MALOC) was outlined, which can combine patient's images with clinical knowledge, as well as efficiently locate the instrument and search the objects' information. The efficiency of data structures was analyzed and experimental results were given in comparison to other traditional data structures. The result of the nasal surgery experiment proves that MALOC is a proper model for clinical knowledge-based ICAS that has advantages in not only locating the operative instrument precisely but also proving surgeons with real-time operation-correlative information. It is shown that the clinical knowledge-based ICAS with MALOC model has advantages in terms of safety and success of surgical operations, and help in accurately locating the operative instrument and providing operation-correlative knowledge and information to surgeons in the process of operations.

Effect of ABCA1-V771M polymorphism on plasma lipid levels and its relationship with coronary atherosclerotic heart disease

Objective To explore the risk association of ABCA1-V771M polymorphism with coronary heart disease (CHD) in Hart nationality in Northwest of China. Methods With case-control study, ABCA1-V771M polymorphism was detected in 204 unrelated Hart nationality people in Northwest of China, and all the subjects by coronary angiography were grouped into 106 cases and 98 controls. The genotypes and alleles frequency distribution of ABCA1-V771M polymorphisms were analyzed by PCR-RFLP analysis, and the clinical statistics of serum lipids were compared and its effects of ABCA1-V771M polymorphism on the plasma lipid levels and coronary atherosclerotic heart disease were analyzed. Results The genotypic frequencies of ABCA1-V771M polymorphism matched well under Hardy-Weinberg equilibrium (P>0.05), V and M allelic frequencies were 33.3% and 66.7%. In comparison with VV VM genotype carriers, MM genotypes carriers had much lower plasma levels of HDL-C (P<0. 001) and much higher plasma levels of TG (P<0. 05). M allelic frequency in CHD group was significantly higher than V allelic frequency (P<0. 05). M allele was related with more severity of atherosclerosis in the coronary artery than V allele (P<0.05). However, there was no obvious difference in the incidence of AMI among carriers with three genotypes of ABCA1-V771M polymorphism (P>0.05). Conclusion ABCA1-V771M polymorphism was not only associated with the plasma levels of HDL-C and TG, but also related to the susceptibility and severity of coronary atheroselerotic heart disease. Moreover, M771 allele appeared to be atherogenie among Han population in Northwest of China.     

健胃愈疡颗粒对慢性胃炎伴幽门螺杆菌感染胃黏膜PAF、PS2的表达及对上皮细胞凋亡的影响

目的观察健胃愈疡颗粒(JWYY)对幽门螺杆菌相关性胃炎胃黏膜乳癌相关肽(PS2)和血小板活化因子(plate-let activating factor,PAF)表达的变化,并分析其可能的作用机制。方法80例幽门螺杆菌感染慢性胃炎患者随机分为2组,治疗组42例给予健胃愈疡颗粒治疗,对照组38例给予西药三联药物治疗。应用胃镜下活检胃黏膜组织快速尿素酶和Warthin-Starry染色法检测幽门螺杆菌,应用Western blot检测PS2、PAF表达变化。应用末端转移酶介导的dUTP切口末段标记法(TUNEL)检测细胞凋亡。第4周复查胃镜。结果治疗组凋亡指数明显比对照组减少(P<0.05),治疗组总有效率高于对照组(P<0.05)。Western blot检测显示:JWYY颗粒可上调PS2并下调PAF的表达,而对照组对胃黏膜PS2和PAF的表达影响不大。结论健胃愈疡颗粒治疗幽门螺杆菌(Hp)相关性胃炎可能与杀灭Hp、上调PS2和下调PAF的表达来抑制细胞凋亡有关。
