  • We investigate the effects of an externally applied magnetic field on the terahertz (THz) emission of Gallium Manganese Arsenide (GaMnAs) films grown via molecular beam epitaxy (MBE). Results show that low Mn-doping in GaMnAs resulted to increased THz emission as compared with a SI-GaAs substrate. Further increase in Mn-doping content resulted to a comparably less THz emission, which is attributed to reduced crystallinity and higher free-carrier absorption. Under an external magnetic field, the contributions of the $B_{up}$ and $B_{down}$-related THz emission were observed to be asymmetric: possibly due to intrinsic magnetic properties of GaMnAs.

  • The study of canine vector-borne diseases in the Philippines started in the 1970s but only gained interest in the past decade. Characterization of such diseases in the Philippines remains incomplete, thus, it is necessary to obtain additional information on the prevalence and diversity of canine tick-borne diseases in the country. In this study, blood samples were obtained at two veterinary clinics in Metro Manila, Philippines from 114 dogs suspected of having canine tick-borne pathogens. Polymerase chain reaction (PCR) was performed on whole blood DNA extracts followed by sequencing, and the following pathogens were detected: Hepatozoon (H.) canis (5.26%), Babesia (B.) vogeli (5.26%), Ehrlichia (E.) canis (4.39%), and Anaplasma platys (3.51%). Additionally, a set of multiplex PCR primers were developed to detect H. canis, Babesia spp. (B. canis and B. vogeli), and E. canis in canine blood. Multiplex and conventional single-reaction PCR results for the 114 dog blood samples were similar, except for one H. canis sample. Multiplex PCR is, therefore, a useful tool in screening infected dogs in veterinary clinics. This study's results, together with those of previous studies in the country, show that canine vector-borne pathogens are an emerging veterinary concern in the Philippines.

  • One of the most common forms of land use change is urbanization. Fortunately, the temporal revisit capacity of remote sensing satellites and their multispectral imaging capability make it possible to monitor this process. Using two Landsat images taken in 1972 and 1989, and one SPOT image taken in 2000, urban growth in Metro Manila is monitored. The extent of urbanization in Metro Manila increased from about 39 percent in 1972 to about 74 percent in 2000, although a slowing of growth was observed in the last decade due to decreasing areas for development. Most cities and municipalities in Metro Manila exhibited urban growth rates higher than the metropolitan average. The drivers and environmental consequences of urban growth were determined as well as the relationship of the extent of urbanization with some socio-economic and environmental variables.

  • Studies focusing on the constantly changing buying behavior and product preferences of a booming teen market are rare and this is particularly true in the Philippines. To address this gap in the literature, this study focused on the supermarket brands of cologne preferred by teens in the Philippines such as Lewis & Pearl (L&P), Johnson's Baby Cologne, Juicy, Bench, Ellips, Fiona, Bambini and Baby Flo which are manufactured by various competing companies. Essentially, this study presented and described the profile and buying behavior of cologne users and non-cologne users and determined whether preferential differences existed between these brands. The respondents consisted of 473 teens all over the Philippines stratified in terms of general location via the three major groups of islands in the Philippines: Luzon, Visayas and Mindanao. Respondents came from selected schools in Quezon City in Metro Manila, Sariaya in Quezon Province, Cebu City, and Digos City to represent the Greater Metro Manila Area, Luzon, Visayas and Mindanao, respectively. Findings showed that almost all of the respondents used cologne at varying degrees. In general, teens use several scents and brands of cologne and continually shift from one scent/brand to another scent/brand. This made it difficult for any company to capture loyal consumers. The most popular brands used by teenagers were Bench (61.7%), Lewis and Pearl (59%), Juicy (42%), Afficionado (32%), Fiona (19.3%), Penshoppe (18%), Bambini (12.6%), Ellips (11.3%) and Zen Zest (7.5%). Fragrance or scent is the top priority of teenagers in choosing a cologne brand, followed by brand name, affordability, bottle design and endorser. The spray bottle type of colognes is preferred even if cologne spray bottles are priced higher than the splash cologne bottle type. Managerial implications of these findings for market players, marketing scholars and prospective investors are presented.

  • The aim of the present study was to investigate and analyze a tendency of the Philippines furniture which are not well-known in Korean market yet, but have been emerging as an OEM base, through the Manila FAME 2012. The study was conducted by visiting some furniture companies in Philippines for the active understanding regarding the current status of the Philippines furniture, in consideration of the material, functional and structural aspects of the goods which were exhibited on the Manila FAME 2012. The methods of the investigation were to research the related literatures concerned and materials had been collected over the internet, to visit the Manila FAME 2012 at work and finally to visit furniture companies in Philippines. Manila FAME has been based on the DTI (DTI: Department of Trade and Industry) through CITEM (CITEM: The Center for International Trade Mission and Expositions) since 1983. The exhibition whichincludes various sorts from furniture, traditional artifacts, leisure goods, gifts, jewelry and clothes is becoming such a potent force by integrating three exhibitions such as Manila Now, CEBUNEXT and Bijoux Cebu, what all had been held before the world economic downturn. The features of the Philippines furniture shown on the Manila FAME are as follows: First, they are focusing on the maximum of function to the exclusion of the decoration and they were mostly made of various kinds of mahogany like jambilina, acacia, bamboo, wisteria and Manila hemp growing up in the Philippines indeed and finally there were a lot of the simple designs of the curved line which were exactly the material nature of the wisteria and Manila hemp.

  • This study was focused on the pork market analysis of the Philippines and the export prospect of Korean pork to the Philippines. The main results are as follows; first, the Philippines have relied on import some quantity of pork consumption every year because climate condition is unfavorable for pig raising and production technologies are undeveloped. Major exporting countries to the Philippines are Germany, Canada, Belgium, Denmark, France, Holland. Second, Korea exported pork of 2,885 tons to the Philippines from Jan. 2004 to Oct. 2004. It was 5.7% of total import pork Third, pork of skinning was 20% higher than the pork of scalding in the consumer price of pork in the Philippines. The consumer price of pork in Korean pork market was 281% in belly, 118% in loin, 106% in leg, 117% in tenderloin higher than the Philippines pork market. Fourth, the export of Korean pork to the Philippines depends on the price of Korean pork market entirely for future, but low grade part of pork and byproducts can be exported to the philippines because consumer price of pork in the Philippines is low compared to Korean pork market.
