Taiwan has disadvantageous conditions for sediment-related disasters such as debris flows. The construction of engineering structures is an effective strategy for reducing debris flow disasters. However, it is impossible to construct engineering structures in all debris flow areas in a short period. Therefore, the government aims to gradually develop non-structural preventive strategies, including evacuation planning, debris flow disaster emergency action system, disaster resistant community program, recruitment of debris flow professional volunteers, debris flow warning systems, and land management strategies, to mitigate disasters and secure the safety of residents. This review describes the processes and effects of recent debris flow non-structural preventive strategies in Taiwan. The average number of casualties prior to the year 2000 was far higher than the corresponding number after 2000 because debris flow evacuation drills have been promoted since 2000 and the debris flow disaster emergency action system has been progressively improved since 2002. Furthermore, the changes in risks caused by debris flow disasters before and after the implementation of non-structural preventive strategies were used to explain the effectiveness of these strategies at the community level. The results showed that softwarebased non-structural preventive strategies can effectively reduce the casualties caused by debris flows at both the national and community levels.

The prolongation of life expectancy and the drastic reduction of fertility rate are the primary cause of an agingworld. It is projected that the elderly (above 65) will increase within the next 25 years by 82% , whereas the new bornonly by 3% . Despite the enormous medical progress during the past few decades, the last years of life are still accom-panied by increasing ill health and disability. The ability to maintain active and independent living for as long as possi-ble is a crucial factor for aging in health and dignity. Therefore, the promotion of healthy aging and the prevention ofdisability in men, must assume a central role in medical research and medical practice as well as in the formulation ofnational health and social policies. Effective programs promoting health and aging will ensure a more efficient use ofhealth and social services and improve the quality of life in older persons by enabling them to remain independent andproductive. The most important and drastic gender differences in aging are related to organs and or systems dependantor influenced by reproductive hormones. In distinction to the course of reproductive aging in women, with the rapid de-cline in sex hormones and expressed by the cessation of menses, aging men experience a slow and continuous decline ofhormones. This decline in endocrine function involves; A decrease of testosterone, dehydroepiandrosterone (DHEA),oestrogens, thyroid stimulating hormone (TSH), growth hormone (GH), insulin-like growth factor-1 (IGF-1), andmelatonin. This decrease is concomitant with an increase of LH and FSH. In addition sex hormone binding globulin's(SHBG) increase with age resulting in further lowering the concentrations of free biologically active androgens. Inter-ventions such as hormone replacement therapy may prevent, delay or alleviate the debilitating conditions which may re-sult from secondary partial endocrine deficiency. Primary and secondary preventive strategies such as the promotion of asafe

Background: Contrast-induced acute kidney injury (CI-AKI) is the third most common cause of AKI in hospitalized patients. Contrast agents mainly cause acute kidney injury through hypoxic damage to renal parenchyma and toxic effects on renal capillaries and tubules. Patients with CI-AKI are more likely to experience adverse events, including longer hospital stay and costs, longer ICU stay, and higher mortality rates. This article elaborates on the definition, epidemiology, risk factors, pathogenesis, and prevention strategies of CI-AKI. Methods: We conducted an extensive literature search using contrast agents and AKI as keywords to identify relevant studies on CI-AKI. Conclusion: CI-AKI is a significant clinical challenge that requires a multifaceted approach to prevention and management. Understanding the risk factors, pathophysiology, and current best practices is essential for healthcare providers to optimize patient care and improve outcomes in those undergoing contrast-enhanced imaging procedures. Hydration therapy is currently the main prevention method, but antioxidants may also become a new strategy.

During the Yushu Earthquake on April 14,2010,a large number of rescuers from sea level or lowlands ascended to the quake areas very rapidly or rapidly less than 24 h. However,Yushu Earthquake is the highest quake in the world at altitudes between 3 750 m and 4 878 m where is a serious hypoxic environment. A high incidence of acute altitude illness was found in the unacclimatized rescuers;the mountain rescue operation changed as "rescue the rescuers". Lesson from the Yushu Earthquake is that the occurrence of acute altitude illness may be closely related to the ascent schedules. This prompted us to study the relationship between ascent rate and the incidence and severity of acute altitude illness;five different groups were compared. The first group was 42 sea level male young soldiers who ascended to quake area very rapidly within 8 h at 4 000 m;the second group was 48 sea level male young soldiers who ascended to 4 000 m rapidly less than 18 h;the third group was 66 acclimatized medical workers from 2 261 m who ascended to 4 000 m rapidly within 12 h;the fourth group was 56 Tibetan medical workers from 2 800 m who ascended to 4 000 m rapidly within 8 h;the fifth group was 50 male sea level workers who ascended to 4 000 m gradually over a period of 4 d. The results showed that the sea level rescuers ascended to 4 000 m very rapidly or rapidly had the highest incidence of acute mountain sickness (AMS) with the greatest AMS scores and the lowest arterial oxygen saturation (SaO2);the sea level workers ascended to 4 000 m gradually had moderate incidence of AMS with moderate AMS scores and SaO2 values;whereas the acclimatized and adapted rescuers had the lowest incidence of AMS,lowest AMS scores and higher SaO2;especially none AMS occurred in Tibetan rescuers. AMS score is inversely related to the ascent rate (r=-0.24,p< 0.001). Additionally,acute altitude illness is significantly influenced by altitude acclimatization. The ascent rate is inversely re- lated to the perio

秉持底线思维防范地方政府债务风险冲击，是新时代重大风险防御攻坚的重要任务。本文考虑经济、财政、债务、体制四类因素，构建了中国地方政府债务风险预警指标体系，进而手工整理330个地级及以上城市数据样本，综合运用TOPSIS-熵值法和K-均值聚类法展开量化评估，从时、空维度识别出地方政府债务风险的演化趋势、分布规律和集聚特征。研究表明，我国地方政府债务风险整体可控，但风险在流动性和结构性层面凸显，东部和中部、东北和西部两大区域在风险程度、高险频次与空间集聚等方面的“俱乐部”分异现象非常显著。本文为防范债务风险凝聚扩散，提供了统筹推进治理转型、密切监测风险态势、设计区域差异化防范策略等政策建议。
