Fourteen volatile components including eight allypyrocatechol analogs were isolated and identified from the essential oil and ether soluble fraction of Philippine Piper bettle leaves (Piperaceae). The major constituents of Philippine Piper betle oil were chavibetol and chavibetol acetate. Capilary GC analysis of the oil showed chavibetol (53.1%), chavibetol acetate (15.5%), caryophyllene (3.79%), allypyrocatechol diacetate (0.71%), campene (0.48), chavibetol methylether (=methyl eugenol, 0.48%), eugenol (0/32%), $\alpha$-pinene(0.21%), $\beta$-pinene(0.21%), $\alpha$-limonene(0.14%), safrole (0.11%), 1.8-cineol(0.04%), and allylpyrocatechol monoacetate. The major component of the ether soluble fraction was allylpyrocatechol (2.38% of the leaves).

SAR imagery offers a reliable mode of image acquisition over tropical countries for various applications. The Philippines participated in two missions to the Pacific Rim by NASA in 1996 and 2000 that saw the deployment of the AIRSAR instrument. This paper discusses the Philippine experience in the use of polarimetric and interferometric radar datasets for diverse applications, including hazards mapping, geologic and geomorphologic mapping, and land cover mapping. The results are discussed in the light of present efforts at capacity building in remote sensing, attempts at operationalizing the use of SAR for priority applications, and future ambitions in remote sensing.

Different countries create their own green building rating system to be in line with sustainable development as a response to the urgent call for solution for Climate Change and degradation of the environment due to rapid population growth and economic development. This study conducts a critical review on the Philippine national voluntary green building rating system, BERDE, in comparison with South Korea's national voluntary green building rating system, G-SEED and U.S. rating system LEED. Their categories, building types assessed, and assessment methods were compared side by side to seek better practice(s) for green building rating assessment for Philippine green building projects.

Government websites provide useful and timely information to the public such as government's history, organizational values, codes of ethics, public services, facts about public official, among others. Using language choice as framework, the study seeks to examine what language is used, in what contents, and in what kind of website. The study employed online observation in 235 Philippine government websites (.gov.ph) via content analysis. As a result, English is overwhelmingly used; while Filipino, the Philippines' national language, and only a handful of regional languages, are minimally used in the contents. Discussion will follow how multilingualism can improve the dissemination of information and communication more conveniently and efficiently from the government to its citizens.

Construction contracts involve the allocation or distribution of the risks inherent to a construction project between or among contracting parties. However, it has been a common practice that only one party drafts the contract due to practical reasons and particular policies of various organizations. Interviews were conducted on some local contractors to gain their meaningful insights and standpoints on the allocation of each risk. These results were compared with the actual risk allocation using the Philippine government standard contract and risk principles from the literature to determine if their considered opinions provide a plausible alternative. A sample application of this evaluation is presented for construction-related risks and risk allocation recommendations are provided in the end.

In this paper, I argue that while area studies in the United States has declined since the end of the Cold War, its area impulse of has emerged in other fields of inquiry, particularly Asian-American Studies. Accordingly, I explain how the collective reflections of Filipino-American scholars on empire, migration, diaspora, and identity point to the consolidation and viability of the transpacific as an area, which spans both the United States and the Philippines. Addressing several problems with this straddling-mainly as criticisms of Filipino-American Studies-I show how the transpacific serves as a bridge between Philippine Studies and Filipino-American Studies, and helps define the boundaries and overlaps between both fields of inquiry.

The changing of clothes in Balagtas' 1860 fictional comedy La filipina elegante y negrito amante (The Elegant Filipina and the Amorous Negrito) is used to explore the ethnic, cultural, and sartorial diversity in 19^th century colonial Philippines. But, how does plurality in men's clothing reflect the socio-economic conditions of the late Spanish colonial period? This paper focuses on the diversity in Philippine men's clothing around 1850 to 1896, taking into account the limited range of colonial archetypes in iconographic and documentary sources. Underscoring the colonial culture that shaped mentalities and tendencies, this study offers insights on how clothing was used and how it was perceived in relation to the wearer. In discussing clothing diversity, distinctiveness was articulated using the work of J.A.B. Wiselius (1875), a Dutch colonial administrator in neighboring Indonesia, who in comparing Spanish and Dutch systems of colonial governance, underscored the Filipino penchant for imitation.

Philippines is the second world supplier of coconut by-products. As its first major genomics project, the Philippine Genome Center program for Agriculture (PGC-Agriculture) took the challenge to sequence and assemble the whole coconut genome. The project aims to provide advance genetics tools for our collaborating coconut researchers while taking the opportunity to initiate local capacity. Combination of different NGS platforms was explored and the Philippine 'Catigan Green Dwarf' (CATD) variety was selected with the breeders to be the crop's reference genome. A high quality genome assembly of CATD was generated and used to characterize important genes of coconut towards the development of resilient and outstanding varieties especially for added high-value traits. The talk will present the significant results of the project as published in various papers including the first report of whole genome sequence of a dwarf coconut variety. Updates will include the challenges hurdled and specific applications such as gene mining for host insect resistance and screening for least damaged coconuts (thus potentially insect resistant varieties). Genome-wide DNA markers as published and genes related to coconut oil qualitative/quantitative traits will also be presented, including initial molecular/biochemical studies that support nutritional and medicinal claims. A web-based genome database is currently built for ease access and wider utility of these genomics tools. Indeed, a major milestone accomplished by the coconut genomics research team, which was facilitated with the all-out government support and strong collaboration among multidisciplinary experts and partnership with advance research institutes.

This paper provides comments on Janus Nolasco's paper and the role that transnational or transpacific studies can play in overcoming the division between Philippine Studies (area studies) and Filipino-American scholarship. It draws attention to the fact that the crossing of localities and boundaries is always historically grounded and that the historical contexts in which Filipino diasporic communities are located vary one from another. It also considers the antecedents of more inclusive approaches to understanding the past and the present, and historical agency.
