Enriching Resources for the Poor: Lessons from the Philippines
Amaryllis Tiglao-Torres 한국사회복지학회 2011 Asian Social Work and Policy Review Vol.5 No.3
The paper provides an overview of the poverty situation in the Philippines, followed by a briefprofile and assessment of two anti-poverty programs: the Kapit-Bisig Laban sa Kahirapan-Comprehensive and Integrated Delivery of Social Services (KALAHI-CIDSS) program and thePantawid Pamilyang Pilipino Program (4Ps). Official statistics disclose that the global economiccrisis in 2008 adversely affected Filipino households, leading to higher levels of poverty especiallyin rural areas. In response, government introduced an Economic Resiliency Program with socialprotection as one component. Sixty-six social protection programs were launched, including thetwo under review. KALAHI-CIDSS and the 4Ps apply poverty reduction strategies that focus onthe development of human and social capital, rather than economic capital. They involve processesand relationships that aim to improve the other dimensions of poverty, such as lack of access toopportunities or deprivation of basic human necessities. Qualitative and quantitative reportsdescribe generally favorable outcomes from both programs. However, these gains at the householdlevel need to be supported by relevant policy, enhanced public services and badly-neededinfrastructure programs from government, in order to sustain achievements culled from socialprotection programs and attain broader developmental impacts.

In this study, empirical site amplifications and S-wave velocity profiles for shallow and deep soils are estimated using earthquake ground motion records in metropolitan Manila, the Philippines. We first apply a spectral inversion technique to the earthquake records to estimate effects of source, path, and local site amplification. The earthquake data used were obtained during 36 moderate earthquakes at 10 strong-motion stations of an earthquake observation network in Manila. The estimated Q value of the propagation path is modelled as $54.6f^{1.1}$. Most of the source spectra can be approximated with the omega-square model. The site amplifications show characteristic features according to surface geological conditions. The amplifications at the sites in the coastal lowland and Marikina Valley shows predominant peaks at frequencies from 1 to 5 Hz, while those in the central plateau are characterised by no dominant peaks. These site amplifications are inverted to subsurface S-wave velocity. We, next, discuss the relationship between the amplifications and average S-wave velocity in the top 30m of the S-wave velocity profiles. The amplifications at low frequencies are well correlated with the averaged S-wave velocity. However, high-frequency amplifications cannot be sufficiently explained by the averaged S-wave velocity in the top 30 m. They are correlated more with the average of S-wave velocity over depths less than 30 m.

본 연구에서는, 필리핀의 마닐라에서 관측된 지진 기록을 통해 얇고 깊은 토양층의 S파 속도 구조 와 경험적 현장 증폭 특성을 평가하였다. 지진 기록에 빛띠 역산법(Spectral inversion technique)을 적용하여 진원, 경로 및 국지적 현장 증폭 효과들을 평가하였다. 사용한 지진 자료는 36회의 중간급 지진들의 기록을 얻었으며, 그 중에서 마닐라의 지진 관측 망에서 강한 움직임을 보인 10곳의 관측점 자료를 이용하였다. 전파경로의 추정 Q값은 54.6f 1.1으로 모사된다. 대부분의 진원의 빛띠(스펙트럼)는 오메가-스퀘어(omega-square) 모형으로 근사 될 수 있다. 현장 증폭 특성은 지표 지질조건에 따라 특유의 특징을 보여준다. 중앙 고지대의 증폭특성은 우세 주파수를 갖지 않는데 비해, 해안 저지대 와 마리키나(Marikina) 계곡에서의 증폭특성은 1~5Hz의 우세 주파수를 갖는다. 우리는 현장 증폭 특성을 S파 속도로 변환한 후에, 증폭 특성과 상부 30m의 평균 S파 속도 구조와의 관계를 검토하였다. 낮은 주파수대의 증폭 특성은 평균 S파 속도와 좋은 상관성을 보인다. 반면, 높은 주파수대의 증폭특성은 상부 30m내의 평균 S파 속도로 충분히 설명되지 않는다. 이것은 30m보다 낮은 심도의 평균 S파 속도와 더 많이 관련되어 있다.
