The Kalanguya Ancestral Domain (KAD) is also located in the area, and it provides a home for the Kalanguya indigenous cultural community. They have fled to the area for a variety of reasons. Despite its rural setting, Carranglan is regarded as a first-class municipality and the largest municipality in Nueva Ecija. This study described and documented the socio-economic profile, and existing issues and problems the Kalanguya Indigenous Peoples (IPs) experienced in their milieu, especially in terms of environmental protection. Recognizing and valuing their perspectives is vital for inclusive development. This study also situated the current status and conditions of the IPs, who generally live below the poverty line and face a range of plights and challenges. As part of safeguarding indigenous rights and interests, this study was undertaken after series of consultations with community elders and leaders. Key informant interviews, household surveys, semi-structured interviews, focused-group discussion (FGD), and direct observations were used to elicit information. Many of the respondents are elementary undergraduates which show that the community had lacked access to education. The following are the primary socioeconomic issues confronting IPs: insufficient access to potable water, suboptimal agricultural productivity, meager monthly income, and a dearth of supplementary and alternative livelihood opportunities. Forest fires, landslides, encroachment of illegal loggers, and concerns about wildlife resources are some of the current environmental issues they have encountered. The local population was supportive of plans and actions targeted at improving the environment. This reveals that the IPs possess unique indigenous forest expertise that enables them to properly manage natural resources.展开更多

Climate change is already happening and affecting many places causing huge problems to coastal ecosystems. Vulnerability and disaster assessment and mapping in coastal areas are essential tasks and undertakings for coastal disaster risk management. The objectives of this study were to assess the climate change vulnerability and disaster risks in the four municipalities (Sta. Cruz, Candelaria, Masinloc and Palauig) of Zambales and to determine the climate change community-based adaptation (CBA) and ecosystem-based adaptation (EBA) strategies. Remote sensing, GIS, secondary data gathering and key informant interview were used to assess vulnerability and disaster risks and mapping in the four municipalities. Survey questionnaire, focus group discussion and key informant interview were utilized in gathering data for the determination of climate change adaptation strategies. Using remote sensing technology, it was revealed that coastline changes have occurred in the shorelines of the four coastal municipalities after a decade. Sea level rise happened in Sta. Cruz and Masinloc, Zambales while there was build-up of soil in the coastline of Candelaria and Palauig, Zambales. Twelve hazard maps, 12 vulnerability maps and 12 disaster risk maps were generated for the three major disasters (flood, landslide, storm surge) in the four coastal municipalities. Based on the flood vulnerability and disaster risk assessment, the municipality of Palauig was found to be the most prone to flooding while the municipality of Candelaria was found to be the most vulnerable to landslide compared to other municipalities. All coastal barangays in the four municipalities were susceptible to storm surge. The four coastal municipalities were conducting community-based adaptation (CBA) and ecosystem-based adaptation (EBA) approaches in order to protect their coastal resources from the damaging impacts of climate change and improve the resilience of their local communities.展开更多

Thus, implementation of climate change adaptation strategies is vital to counter the effects of climate change. It is in this context that this study was undertaken to analyze the need or urgency to adopt community and ecosystem-based adaptation strategies among selected coastal barangays (villages) of Masinloc, Zambales, Philippines. Various methods of data collection were utilized such as secondary data collection, primary data collection through household survey, key informant interviews, and focus group. Results of the study indicate that in terms of community-based adaptation strategies, all of the seven barangays in Masinloc have moderate necessity. However, only Barangays Bani and Collat have high adaptation capacity in terms of infrastructure and disaster preparedness. The execution of several community-based adaptation strategies helps these barangays to respond immediately and appropriately to the moderate risk posed by floods and storm surges. On the other hand, in terms of ecosystem-based adaptation strategies, all of the seven barangays have moderate necessity which implies that they have moderate vulnerability and risk to flood and storm surge but have high adaptation capacity in terms of the conservation and protection of coastal resources (mangroves and sea grasses). The barangays implemented the necessary ecosystem-based adaptation mechanisms that they might need in the future. This only means that when they are faced with disaster, the local communities are prepared to respond appropriately and to cope up with the effects of extreme weather events which lead to floods and storm surge. Even though most of the ecosystem-based adaptation strategies are conducted by the seven barangays, there are several community-based adaptation strategies that are still lacking which will protect them from the effect of floods and storm surges. Hence, carrying out the missing adaptation strategies, both community-based and ecosystem-based, will help in improving the adaptive capacity of the affected barangays and will help them become more resilient to the amplified effects of climate change.展开更多

The aim of this study is to evaluate the role of inflammatory markers in diagnosis of acute appendicitis. Material and Method: The study includes 77 cases with histopathologically proven acute appendicitis and 17 control cases. Blood samples were obtained from all cases and C-reactive protein (CRP), Granulocyte Colony Stimulating Factor (G-CSF) and Total Antioxidant Capacity (TAC) were measured. Findings: In cases with acute appendicitis, CRP and G-CSF levels were found to be related to acute appendicitis;however, TAC was not affected by the disease process. Moreover, CRP and G-CSF levels were correlated with the disease severity. Conclusion: Both CRP and G-CSF can be used in diagnosis of acute appendicitis. Furthermore, increased CRP level can be a marker to show advanced cases. However, G-CSF is not an effective marker to show disease severity.展开更多

Called desert-scrub, these shrubs form a predominantly vertical clumps protruding from the soil-level, thereby significantly increasing the coefficient of turbulent heat transfer from the surface. The impact on global and desert-belt climate of changes in these two surface characteristics was simulated by a multi-layer energy balance tnodel. Evaluated only as a forcing to a further climatic change (that is, without accounting for any possible feedbacks) the results are: if vegetation (such as apparently existed under the warmer climate of 6,000 BP ) grows over large areas in the arid, currently bare-soil regions, the annual Northern Hemisphere surface temperature increases by 0.7t (by 0.6'C in July ), the surface temperature over land in the 20-30°N zone increases by 0.9℃ in both the annual and the July means, and the land-ocean annual temperature contrast in this zone increases by 0.25℃(0.2° in July). These results represent the combined influence of the reduction in the surface albedo and of the increase in the coefficient of turbulent heat transfer. In the desert-belt zones, the increase in the transfer coefficient sharply reduces the land temperature and the land-ocean temperature contrast from the values produced by the albedo change alone. This reduction must be attributed to the increased land-to-ocean circulation (which our model does not evaluate explicitly). Considering that a stronger circulation (resulting from land-ocean temperature contrast) generally forces a higher rainfall, the vegetation which emerged in the arid regions during the post-glacial optimum should be considered a significant positive feedback towards a still warmer, and also a more pluvial, climate. Our study may have implications for the 21st century, if the global warming expected from the enhanced greenhouse effects is accompanied by increased precipitation over the continents.展开更多
