  • Coenurosis is an important zoonotic helminthic disease caused by the larval stage of the tapeworm Taenia multiceps. This parasite typically infects the brain of the intermediate hosts, including sheep, goat, cattle and even humans. We report a case of T. multiceps infection in a yak confirmed by clinical symptoms, morphological characteristics, and molecular and phylogenetic analyses. The coenurus was thin-walled, whitish, and spherical in shape with a diameter of 10 cm. The parasite species was identified as T. multiceps by PCR amplification and sequencing of the 18S rRNA, cox1 and nad1 genes. Three gene sequences all showed high homology (all above 97%) with the reference sequences from different hosts. Moreover, phylogenetic reconstructions with the 3 published Taenia gene sequences confirmed that the Qinghai yak isolate was closely related to T. multiceps. Although there are advanced diagnosis and treatment methods for coenurosis, early infection is difficult to diagnose. Importantly, the findings of yak infection case should not be ignored due to its zoonotic potential.

  • This study was carried out to determine the pathogen-causing diarrhoea in sheep Ovis aries in the Qinghai Tibetan Plateau Area, China. A trophozoite was identified as species of ciliate alveolates infecting the sheep based on morphological characteristics examined by microscope. It was mostly spherical, colourless and transparent, with many vesicles. Macronucleus and contractile vacuoles could not be distinguished. Size of the trophozoite was $80-180{\times}70-150{\mu}m$ and its surface was covered with cilia. Molecular analysis based on sequences of 18S rRNA and ITS genes confirmed the ciliate species as Balantidium coli. According to the literature, there have been many epidemiological investigations of B. coli infection in pigs, monkeys and humans. To our knowledge, this was the first report of B. coli infections in sheep in the Qinghai Tibetan Plateau Area of China, or eleswhere around the world. Importantly, the sheep case was rare but raised our concern that B. coli may spread across species and expand its host range.

  • Objective: The aim of this study was to clone the mRNA sequence of the Acyl-CoA dehydrogenase long chain (ACADL) gene of goats and explore the effect of ACADL on the differentiation of subcutaneous fat cells on this basis. Methods: We obtained the ACADL gene of goats by cloning and used quantitative real-time polymerase chain reaction (qPCR) to detect the ACADL expression patterns of different goat tissues and subcutaneous fat cells at different lipid induction stages. In addition, we transfect intramuscular and subcutaneous adipocytes separately by constructing overexpressed ACADL vectors and synthesizing Si-ACADL; finally, we observed the changes in oil red stained cell levels under the microscope, and qPCR detected changes in mRNA levels. Results: The results showed goat ACADL gene expressed in sebum fat. During adipocyte differentiation, ACADL gradually increased from 0 to 24 h of culture, and decreased. Overexpression of ACADL promoted differentiation of subcutaneous adipocytes in goat and inhibited their differentiation after interference. Conclusion: So, we infer ACADL may have an important role in positive regulating the differentiation process in goat subcutaneous adipocytes. This study will provide basic data for further study of the role of ACADL in goat subcutaneous adipocyte differentiation and lays the foundation for final elucidating of its molecular mechanisms in regulating subcutaneous fat deposition in goats.

  • This study was designed to survey the degrees of career plateau, job satisfaction, and turnover intention of hospital nurses, as well as to identify the relationship among them. We surveyed 239 nurses working at five different hospitals in J city and C city. Data collection was conducted between April 1 and April 30, 2016. The data was analyzed using SPSS 23.0. This study shows that the significant factors influencing job satisfaction were content plateau and structural plateau, which account for 55.0% of the variance. It also shows that the significant factors that influence turnover intention were structural plateau, present clinical career, content plateau, and working department, which account for 43.0% of the variance. As such, we identified that a decrease in the content plateau of hospital nurses enhances job satisfaction and that a decrease in structural plateau reduces turnover intention. The results indicate that a systematic managerial strategy for nursing resources should be developed and applied in the nursing field. This strategy should supplement the content plateau by job redesign and job enrichment. In addition, to increase retention of skilled nurses and to achieve superior organizational performance, as well as to contribute to the success of hospital nurses, supplementation of the structural plateau by adopting and applying a career ladder system is important.

  • The Antarctic high plateau offers exceptional conditions for infrared and terahertz astronomy, as well as for programs requiring long, uninterrupted periods for measurements made with high cadence and photometric precision (i.e. time domain astronomy). In this review we summarise the special conditions of the Antarctic plateau which facilitate these observing regimes. We also outline some high profile science programs in each that could be conducted most effectively from the Antarctic high plateau, involving the first light in the Universe, the life cycle of our Galaxy, and the equation of state for the Universe. Three high plateau sites are under particular consideration for furthering such scientific programs{Dome A, Dome F and Ridge A. We summarise the activity underway at each site, which includes the building of new stations and the construction of facilities for optical, infrared and terahertz astronomy, as well as the plans for their future development.

  • Purpose: In this study, factors affecting career satisfaction of nurses were explored in the career development and career plateau. Methods: Participants were 143 nurses drawn from a general hospital in Busan. independent t-test, one way ANOVA and Hierarchial multiple regression with SPSS/WIN 18.0 program were used for data analysis. Results: The mean score of career satisfaction was 2.85/5, Career development was 2.99/5, and career plateau obtained 2.53/5. The extent of the career satisfaction differ according to age(F=3.60, p=.030), marital status(t=2.42, p=.017), current position(F=6.61, p=.002), total clinical career(F=3.36, p=.023), and work unit(t=0.95, p=.029). The influencing factors in career satisfaction of clinical nurses were organizational career management, career plateau and individual career planning. $R^2=.415$. Organizational career management was the highest significant predictor of career satisfaction(${\beta}=.325$). Conclusion: Factors influencing career satisfaction were organizational career management, career plateau and individual career planning. Thus a program for career development of organization is needed.

  • This study examines the direct effect of workforce restructuring on the withdrawal behavior and mediating effect of perceived job insecurity. Empirically it also explores the moderating effect of career plateau and procedural justice on the above relationship. The study focuses on the mediating role of job insecurity and the moderating role of career plateau in relations to procedural justice, which will concentrate on the relationship between workforce restructuring and withdrawal behavior. For the empirical study, we collected and analyzed 442 survey data from employees of Korean companies. SPSS 24 is used for reliability, correlation and regression analysis. The results of the empirical analysis are as follows. First, perceived job insecurity mediated the relationship between workforce restructuring and withdrawal behavior. Second, content career plateau had a negative moderating effect on the relationship between workforce restructuring and job insecurity. Finally, the moderating effect of procedural justice was not supported. This research extend workforce restructuring and career plateau related studies; by exploring the mediating variable and moderating variable on the relationship between workforce restructuring and the pertaining outcomes. Based on the results, we provide theoretical and practical implications along with future research recommendations.
