    Comparison of direct microscopy and concentration techniques using household bleach for the detection of acid-fast bacilli in sputum
    Bernabe, John Marvin S.; Biaoco, Beverly G.; Castillanes, Melvic A.; Fernandez, Ia Jean F.; Geraldoy, Ruffa V.; Molina, Ryge Albert D.; Pluma, Zyra April D.; Que, Agnes Karen B.; Servidad, Mercy Jeane C.; Tamayo, Kyria Mae Marre P. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2008-03-29)
    Several published studies have demonstrated that the sedimentation and centrifugation concentration techniques which utilize sodium hypochlorite are more efficient in detecting acid fast bacilli in sputum smears compared to the conventional direct smear method. This study was conducted to (1) compare the proportion of AFB-positive samples by direct microscopy with the household bleach centrifugation concentration technique; (2) compare the proportion of AFB-positive samples by direct microscopy with the household bleach sedimentation concentration technique;(3) compare the proportion of AFB-positive samples by household bleach sedimentation with the centrifugation concentration techniques; and (4) compare the cost of the direct smear method, centrifugation concentration technique, and sedimentation concentration technique for detection of AFB. Sputum specimens were collected from TB-DOTS clinics in Miag-ao and San Joaquin, Iloilo and from Medicus laboratories in Iloilo City. The specimens were then processed through the direct smear method, centrifugation concentration method, and sedimentation concentration method. Out of 174 sputum samples included in this study, results revealed that (1) there was no significant difference in the proportions of AFB-positive slides detected using the direct microscopy and centrifugation concentration technique; (2) there was no significant difference in the proportions of AFB-positive slides detected using the direct microscopy and sedimentation concentration technique; (3) there was no significant difference in the proportions of AFB-positive slides detected using the centrifugation and the sedimentation concentration techniques; and (4) simple cost analysis of the three methods suggests that the direct smear method is the most cost efficient. The findings indicate that whichever method is used would yield almost the same proportions of AFB-positive slides. Internal quality control should be maintained throughout the laboratory work to obtain reliable results, as it is the manner of processing that determines the outcome of this study and its validity.

    Comparative analysis of the program format of TV Patrol and 24 Oras
    Berja, Alice Bernadette F.; Nidoy, Michelle Gay M. (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 2013-04)
    This descriptive-comparative study aims to determine the program format of the two mainstream TV news programs here in the Philippines: TV Patrol (ABSCBN) and 24 Oras (GMA). There are two types of TV news program format, standard format and tabloid format. Both formats are guided by four elements: segment, news selection, news delivery and language. Survey was used in measuring the knowledge of Ilonggo viewers on the program format of TV Patrol and 24 Oras. The study covered 12 barangays in Iloilo City with 400 respondents. Results of the data-gathering process showed that TV Patrol is in tabloid format while 24 Oras is in standard format. News delivery is the most tabloid element of TV Patrol while Language is the most standard element of 24 Oras. Both formats have implications to the viewers’ knowledge and perception towards the reality of news stories.

    Gender analysis on the modes and extent of participation in Community-based Fishery Resource Management (CFRM) project in Malalison island, Culasi, Antique
    Benliro, Patriana Z P.; Eraste, Concepcion E. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2003-03)
    A Gender Analysis on the Modes and Extent of Community Participation on CFRM in Malalison Island, Culasi, Antique was conducted in June 2002-Feruary 3003. The study aimed to determine the modes and extent of participation in Community- based Coastal Resource Management through the Community-based Fishery Resource Management (CFRM) Project using Program Monitoring with interview and focused group discussion. The difference on the modes and extent of participation of sex and membership in the association was also assessed. The study found out that male and female modes of participation in CFRM had no significant difference. The difference was in the extent of their participation, which was caused by the social roles they played. On the other hand membership in the organization was found to be a significant variable in analysing the modes and extent of participation.

    Constraints and challenges on the use of emerging media among public high school teachers
    Benjamin, Louangel Jei D.; Guillen, Kaya A. (Division of Humanties, College of Arts and Sciences, University of the Philippines Visayas, 2022-06)
    When the COVID-19 pandemic hit the Philippines, the Department of Education implemented distance learning which is primarily module-based to accommodate those that do not have the resources. However, literature has shown that teachers still use emerging media in order to communicate with their students. This study aimed to find out the constraints and challenges experienced when using emerging media during distance learning. It was guided by the social presence theory which centers on the differences in the degree of social presence using telecommunications media and how these differences affect the communication in terms of constraints and challenges. Using quantitative research design and a descriptive survey method, public junior high school teachers were given survey questionnaires to report their experiences on the use of emerging media. The results of this study revealed that emerging media plays a significant role despite distance learning being modulebased. The challenges are caused by the digital divide that led to the lack of budget and technological infrastructure while constraints are more concerned with the intimacy and immediacy depending on where the type of emerging media falls on the social presence scale. Overall, the challenges and constraints encountered by the respondents in using emerging media affects the communication and by extension, the teaching and learning experience in distance learning.

    Beloya, Marian Kristina C.; Camancho, Rea Micah C.; Perez, Mary Lydannie V.; Villanueva, Ma. Emilie M. (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 2005-10-21)
    This study is about responsibility on the use of media technology specifically cellular phones. The study is done through a survey measuring on respondents’ behavior and awareness of social responsibility pertaining to the use of cellular phone. Residents of UPV Miagao dormitories (Balay Apitong, Balay Gumamela, Balay Lampirong, Balay Kanlaon, and Balay Madyaas) were chosen as respondents to the study. The results of the study show that the respondents are Aware of their social responsibility but they are Sometimes responsible in using their cellular phone and as senders and receivers. Therefore, the UPV Miagao dormitory residents are Quite Socially Responsible on the use of media technology specifically cellular phones.

    Fecundity and Oocyte size in the flyingfish (Cheilopogon arcticeps) from Lanuza Bay, Surigao Del Sur
    Belaza, Yeuclaire Dorothy M. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2018-06)
    The relationship of fecundity and oocyte diameter to body size and other reproductive aspects of the flying fish, Cheilopogon arcticeps in Lanuza Bay were investigated in this study. Gravimetric method or weight method was used in order to estimate the fecundity of 35 mature female C.arcticeps ranging from 17.8-23.6 cm standard length. Total fecundity of C.arcticeps ranged from 1,126 - 41,684 while its oocyte diameter ranged from 0.8 -3.6 mm. The relationship of fecundity to standard length (SL) showed variable results and poor correlation. This may be indicative of a unique reproductive strategy of this species. Egg size to standard length showed an increasing trend but a weak correlation. In general smaller egg diameters were observed in smaller size class SL and bigger egg diameters appear in larger SL. The relationship of fecundity to gonad weight showed a positive linear correlation and increasing data .Thus as gonad weight increases, fecundity increases too. The correlation between fecundity and total length shows a weak relationship, however the correlation between fecundity and gonad weight show a stronger relationship. The present study aim to exhibit additional information on the rare documentation of flyingfish in the country.

    The socio-economic factors that affect the in-migration decision of street vendors in downtown Iloilo City
    Bebis, Mary Grace C.; Benetiz, Earl Cexanne B. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2010-03)
    The lack of employment opportunities and poverty encourages migration from the rural to urban areas. This study aimed to determine the socio-economic factors that affect the in-migration decision of street vendors in downtown Iloilo City. The data were gathered through purposive sampling of sixty street vendors. The results indicated that the respondents main reason for migrating is the perceived availability of job opportunities in the city. However, information asymmetry, disproved this notion. Age is the only significant factor which contributed in migration decision in this study. The younger an individual is, the higher is the tendency to migrate. Currently, there are no local policies geared towards the welfare of the street vendors. It is highly recommended that the street vendors should be relocated at one place and development of the neighboring towns of Iloilo City be effected to curb the influx of in- migration.

    Level of intention to use GIS among online journalists
    Bayog, Katrina Coleen; Buensuceso, Dayanara; Sabando, Fydah Marie (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 2015-05)
    Geographical Information System or GIS is a new technology being used by different international news organizations to provide a more comprehensive reporting for their consumers. GIS is a data visualization tool which maps out the news articles linked to where they have happened, providing a more sophisticated visual output. However, despite the potential of GIS in journalism and reporting, there has been a limited use of this system in local and national news reporting, both online and on print in the Philippines. This study looks into the level of intention to use GIS by local online newspaper journalists in online news reporting. Using a framework derived from the Technology Acceptance Model and the Unified Theory of Acceptance and Use of Technology, the researchers employ a non-experimental relational study design to determine which is the strongest predictor for intention to use GIS among the three constructs of UTAUT model—Performance Expectancy, Effort Expectancy and Social Influence. Their findings show that PPI-member journalists in Western Visayas had a high intention to use GIS in their online news reporting. The researchers recommend, for future study, the employment of the “actual use” construct of the Technology Acceptance Model (TAM) and/or the Unified Theory of Acceptance and Use of Technology (UTAUT). They also encourage an experimental design with the controlled and uncontrolled variables in conducting the test. This can give an accurate comparative depiction of journalists who were exposed to the explainer video from those who were not exposed.

    Community structure of riverine mangrove stand in Brgy. Talokgangan, Municipality of Banate, Iloilo Province
    Belaño, Keith Dominador L. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2001-04)
    The community structure of riverine mangrove stand in Brgy. Talokgangan, Municipality of Banate, Iloilo was studied. Ten “true” mangrove species representing seven families were encountered in the “mangals” of Balandra creek community in Brgy. Talokgangan. They were Avicennia marina, Avicennia lanata and Avicennia alba representing Family Avicenniaceae; Rhizophora apiculata and Rhizophora mucronata under Family Rhizophoraceae; Sonneratia alba of the Family Sonneratiaceae; Excoecaria agallocha under Family Euphorbiaceae; Camptostemon philippinense of the Family Bombacaceae; one from the Family Meliaceae namely Xylocarpus granatum, and Family Palmae represented by Nypa fruticans. Stand Basal Area was computed highest in Station 1 with 10.22 m2/ha. Station 1 was also the densest among the four stations with a density value of 2533 trees/ha. In terms of data evaluated per zone, the landward zone has a Stand Basal Area of 10.87 m2/ha which is slightly higher than the middle and riverward zones. The middle zone, however, was found to be the densest with 1850 trees/ha. The most dominant station was Station 1 with the highest Index of Dominance of 0.3319, however, was found to be the least diverse station. The highest Index of Diversity was computed in Stations 2 and 3, with diversity indices of 0.8976 and 0.8989 respectively. Avicennia marina was found common in all stations and the most dominant, making it the most important mangrove species. They were found to occupy the whole site, growing abundantly in wide range of conditions from areas frequently inundated by tidal flow in Station 1 to the firmer muddy substratum in the back mangrove areas. Rhizophora apiculata and Rhizophora mucronata was observed to occupy waterlogged soil conditions. Excoecaria agaliocha tend to flourish in firmer muddy substratum in open sites, whereas, Xylocarpus granatum was observed to occupy zones where salinity is lowest in areas rarely affected by tidal flow. Sonneratia alba and Camptostemon philippinense tend to grow in zones directly inundated by tidal flow.

    Hallyu: The K-Pop phenomenon a critical analysis of K-POP music
    Beguas, Ma. Veronica D.; Sinda, Krisha Kamille M. (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 2013-04)
    This thesis is a critical analysis of the factors that makes K-Pop music popular. The researchers wanted to objectively look at the music genre since there are only few studies of K-Pop despite its growing global attention in the entertainment industry.The study first traced the emergence of K-Pop, followed by the discussion of its packaging and promotion strategies as well as its implications on Philippine local music industry. The study used Commodification of Culture by Hannah Arendt and Theodore Adorno (1973) and the assumptions of Transnational Media Management Theory by Barbara Parker (1996). The proponents interviewed experts: 3 from the academe, 2 from the media organizations, 2 from the music industry and 2 representatives from K-Pop fan groups and with the Director of Korean Cultural Center in the Philippines. The proponents also did library and online research. The study found out that K-Pop started mainly from K-Dramas and that a combination of well-produced music and music videos, packaging and promotion strategies of Korean entertainment companies, both government and private sector efforts as well as the good adaptation to advance technologies have made K-Pop a global success.
