The disease stages influence treatment protocols, ranging from surgery and radiotherapy for early stages to chemotherapy and radiation for advanced stages, but survival rates decrease as the cancer progresses. Objective: The objective of this study is to determine the economic impact of the disease and recommend cost-efficient strategies for prevention and treatment. Methods: A population-based, cross-sectional study was conducted with a stratified sample of cervical cancer patients from selected healthcare facilities across Bangladesh. Data collection involved structured interviews and validated questionnaires. The study measured the economic impact, treatment costs, and other related expenses. Quantitative data analysis was performed using SPSS v22, MS-Excel, and R Programming, with Multivariate regression analysis and Post Hoc tests, including the chi-square test, applied to selected indicators. Results: All respondents in the study were female, aged 34 - 75, with 72.3% aged 40 - 50. Most were illiterate (38.6%) and housewives (95.0%). Additionally, 98% were married, 85.10% married before age 18, and 46.50% experienced their first menstruation before age 12. Families typically had a monthly income of 10,000 - 30,000 Taka, spending similar amounts on treatment. Significant relationships were found between educational qualifications, occupation, personal hygiene practices, history of oral contraceptive use, and age of marriage (p Conclusion: The article emphasizes the impact of monthly family income on cervical cancer treatment costs, stressing the need for comprehensive support services to address the financial and emotional burdens faced by patients. Improving access to quality care and implementing measures can enhance outcomes for cervical cancer patients in Bangladesh.展开更多

Expanding rural residents' consumption becomes a necessity for enlarging domestic demand, solving three agriculture problems and promoting sustainable and rapid economic development. The research shows that since invigorating old industrial base in Liaoning, the contribution rate of rural residents' consumption to economic motivation is low and unstable, which has become one of the choke points for the development of economy. By using the grey correlation method, the influences of rural residents' consumption in different periods to GDP per capita are analyzed, the results show that the consumption level of rural residents were increasing, but their contribution rate on economic growth showed the descending tend. The residential expenses stay in the major position of consumption expenses; the education and entertainment products and service consumption play an important role; the growth of transportation and telecommunication is slow; the expenses on medical care are low and its contribution rate on economic growth is relatively weak. The countermeasures on developing rural economy, increasing rural residents' income, improving rural consumption environment, accelerating rural infrastructure construction, constructing and perfecting rural social security system and expanding rural consumption credit market are put forward to expand rural residents' consumption demand and realize the sustainable development of economy.展开更多

The underlying reasons behind are largely owing to the established ancient relations and religious fulfillments like performing pilgrimage as well as pursuing religious studies in highly respected institutions. Malaysia's relation with the Islamic Republic of Iran, however, has shown steady progress of development since the end of 1960s and onwards. Although Iran has become an Islamic Republic after the eruption of the Revolution in 1979, the relations remain intact in spite of the potential expansion of Iran's religious ideology, Shi'ah, among Malaysian Muslim communities. On top of that, with Iran now facing economic sanctions due to its nuclear programs, both countries continue to bolster their relations, especially in political and economic interactions. Contemporarily, both Malaysia and Iran are closely working together to further enhance the level of their relations. The leaders of both countries have quiet regularly exchanged visits and have also actively ventured into promising business opportunities. Iran ranked as the Malaysia's third West Asian trading partners along with the United Arab Emirates (UAE) and Saudi Arabia, provides a lot of opportunities for Malaysia to seize onto. In other words, Malaysia's contemporary relations with Iran will evolve beyond the dogma of the Iranian Revolution in 1979.展开更多

It emphasizes neoliberalism at home, less government regulations, more growth and weakening the welfare state. Intemationally, Trumponomics embraces protectionism and nativism with a focus on US economic interests. Trumponomics caters to the lower-middle classes, a reflection of the country's current economic and diplomatic challenges. Trumponomics will bring uncertainty to China-US economic and trade relations. China should carefully study the policies of the Trump administration and prepare contingency plans.展开更多

China-Singapore Suzhou Industrial Park, China-Singapore (Chongqing) Demonstrative Initiative on Strategic Connectivity, and the compatibility between Singapore ~ development strategy and China' s Belt and Road initiative are testimony to the ever-growing bilateral economic and trade links. The deepening and expanding economic and trade relations between China and Singapore enhance political mutual trust, propelling China's economic and industrial upgrading. At the same time, they exert a positive influence on the development of China-ASEAN relations and an effective implementation of the Belt and Road initiative in Southeast Asia.展开更多

Generally speaking, the nine years between 2007 and 2015 saw non-stop progress in China and US trade and economic ties. The China-US interdependent and complementary economic and trade connections ensure that bilateral relations are constantly developing and merging following their interdependent paths;the global challenges, such as the financial crisis and recent extreme weather events, have allowed China and the US to be in the same boat,weathering these different forms of turbulence. Decisions on important domestic policies and disputes can now be discussed earlier and effectively following on from the construction of multi-dimensional crisis management mechanisms. But undeniably there are unsettled and conflicting points in their relations, such as the fact that the US strategically excludes China from its free trade agenda, not willing to accept many everyday items manufactured by China. This is a major obstacle preventing their relationships deepening. History tells us, in future, if both sides could have a bigger vision, relations would better develop, for the new type of major power relations and the subsequent road would be less rocky and bring more benefits for the peoples of both countries.展开更多

The discrete spatial variation in the thickness of these deposits, in combination with subsidence due to groundwater withdrawal, generates differential settlements and aseismic ground failure (AGF) characterized by a welldefined scarp. In cities, such AGF causes severe damages to urban infrastructure and considerable economic impact. With the goal of arriving to a general criterion for evaluating the economic losses derived from AGF, in the present work we propose the following equation: ELi = PVi*DFi. Where PVi is the value of a property “i”, and DFi is a depreciation factor caused by structural damages of a property “i” due to AGF. The DFi is calculated empirically through: . This last equation is based on the spatial relations of coexistence and proximity of property polygons and the AGF axis. The coexistence is valued as the quotient of the affectation area divided by the total area of the involved property;and the proximity to the AGF axis is expressed as the inverse of the perpendicular distance from the centroid of the property polygon to the AGF axis. The sum of these terms is divided by two to determine the percentage that affects the property value (PVi). These equations are relevant because it is the first indicator designed for the discrete assessment of the economic impacts due to AGF, and can be applied to real estate infrastructure from either urban or rural areas.展开更多
