The aim of this article is to describe and analyze the changes in the environment and for modem governance. The study attempted to answer the question： what the challenges faced by today＇s managers in the management of enterprises. This article is based on the analysis of literature, and diversified in cross time.

Contemporary Patterns of Management of Tetralogy of Fallot:Data from a Single Center in China

Background:There is scarce research on large cohorts with tetralogy of Fallot(TOF)from China.The database in Fuwai Hospital was reviewed to ascertain current trends in the management of TOF and to determine the prevalence of various surgical techniques and the optimal early outcome.Methods:This cross-sectional study included 1861 patients who underwent surgery between 2012 and 2017 and were aged 0-18 years old with a primary diagnosis of TOF.A total of 1760 eligible patients were included in the analyses.Results:A total of 1683 patients underwent repair of TOF as a one-stage operation(primary repair).Sixty-one patients underwent repair of TOF after prior palliation.Of patients who underwent one-stage repair(n=1683):858 were 6 months to 1 year old,421 were 1 to 2 years old,251 were 2-18 years old,and 145 were 3 to 6 months old.Of patients who underwent repair following prior palliation(n=61),58(95.1%)were older than 1 year of age.Of 1744 complete repairs,986(56.0%)had annulus-sparing(AS)repair.Total in-hospital mortality was 15 of 1744(0.9%)for complete repair(including one-stage and staged repairs).The total incidence of the optimal early outcome was 78.2%in terms of a composite of the absence of death in the first year,significant right ventricular outflow tract obstruction,significant pulmonary valve insufficiency,or catheter or surgical reintervention.Conclusions:Surgical correction in patients with TOF can achieve an acceptable outcome in terms of death and reintervention.Primary repair at 6 months to 1 year of age is the most prevalent strategy in our centre.However,the relatively high incidence of early undesirable surgical adequacy of the pulmonary valve(PV)represents a wake-up call.

Integrating Activity-Based Costing （ABC） and Theory of Constraint （TOC） for Improved and Sustained Cost Management

Implementing effective cost management approaches has recently gained momentum due to intense competition and increasing customer demands. Moreover, effective cost management approaches have contributed to firms＇ competitive advantage in relation to cost leadership strategy. Consequently, firms have implemented contemporary cost management systems, such as activity-based management, business process re-engineering, life-cycle costing, target costing, and theory of constraint （TOC）, to enable them to become low-cost producers and compete effectively and sustain their performance. Furthermore, focusing on cost management to improve profitability has led to the integration of activity-based costing （ABC） and TOC. Therefore, the aim of this study is to review literature and discuss how integration of ABC and TOC can result in improved and sustained cost management. While these methods have different approaches in addressing cost management, treating them as complementary cost management approaches can result in improved cost management due to improved product costing, improved cost reporting, improved product-mix decisions, and improved cycle-time management. Improvement in cost management will then result in sustained cost management. Sustained cost management is further enhanced with the investment in information customer and shareholder value technology that supports cross-functional decision making to continue creating to remain competitive in the market.
