Item Heavy metals (Cr, Cu, Pb, and Zn) concentrations of road-deposited sediments within six public plazas in Iloilo CityCaceres, Rizza Daphet E. (Department of Chemistry, College of Arts and Sciences, University of the Philippines Visayas, 2011-04)Contamination from overland transportation is an unavoidable result of urbanization. Cr, Cu, Pb, and Zn arc common heavy metals introduced to the environment by transportation. Road-deposited sediment (RDS) samples were collected from six public plazas (Villa Plaza, Molo Plaza, Mandurriao Plaza, Plaza Libertad, Lapaz Plaza and Jaro Plaza) in Iloilo City from March 2010 to May 2010. 0.5M HC1 was used as extractant and heavy metals (Cr, Cu, Pb, and Zn) concentrations were determined using Flame Atomic Absorption Spectrophotometer (FAAS). The mean concentrations of Cr, Cu, Pb, and Zn in road-deposited sediments from six plazas were 8.79 ± 1.93, 40.90 ± 24.21, 60.74 ± 22.32, and 164.25 ± 25.0 mg/kg, respectively. Metal enrichment of Cr, Cu, Pb and Zn were approximately xl, x8, x7 and x18 more than the background values respectively. There was no significant temporal variation in metals concentrations of RDS between sampling collections. Generally, RDS from Plaza Libertad has the highest metal concentrations. Cu and Pb metals were highly correlated (R2 = 0.891) indicating possible similar sources. A good correlation (R2 = 0.918) was observed between Pb concentration and the number of vehicles that pass along the plaza per hour. Heavy metal concentrations in sediments from plazas have low hazard quotients but bioaccumulation of metals in the body could cause health effects. Efficiency of digestion procedures varied depending on characteristics, texture and composition of road-deposited sediments. 0.5M HC1 digestion was used because it is simple, cost-effective, time-efficient and it leaches out meaningful amounts of bioavailable metals. Using HC1 as extractant simulates human digestion since human stomach contains HC1 that could leach out metals if road-deposited sediments were ingested.Item Factors affecting compliance of Iloilo City jeepney drivers (Molo via City High and Jaro Mandurriao) with anti-smoking ordinance: An assessment of Local Government Unit (LGU) ordinance implementationBiboso, Rissa A.; Salar, Edmund B. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2004-03)The study sought to determine the factors affecting compliance of Iloilo City jeepney drivers to the anti-smoking ordinance, as well as assess the implementing mechanisms of the LGU in enforcing the said ordinance. Forty three (43) jeepney drivers plying two routes served as the respondents of the study, seven drivers from the Molo via City High route and thirty six respondents from Jaro Mandurriao. Likert scales were used to measure the respondents’ level of awareness regarding the ordinance and level of perception of legitimacy of authority. On the other hand, rating scales were used to rank the respondents’ reasons for compliance to the anti-smoking ordinance. Results showed that age and educational attainment do not affect the level of awareness and perception of legitimacy of authority of the jeepney drivers. Furthermore, the primary reasons for the jeepney drivers’ compliance to the anti-smoking ordinance were their level of awareness of the ordinance, the P300.00 fine for violators, confiscation of driver’s license and the presence of the Anti-smoking Task Force. Results showed that the implementing mechanisms employed by the LGU were effective.Item Public utility jeepney drivers in Bacolod City, Negros Occidental: Socio-economic conditions and income differentials analysisBanagodos Lorena Joy P. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1997-04)Benchmark information was sought regarding the socioeconomic conditions of jeepney drivers and their households from a sample of 111 respondents in Bacolod City, Negros Occidental. This profile focused on their socio-demographic and housing characteristics as well as their household expenditure patterns. Several aspects of the driving occupation was also discussed. Income differentials analysis was also used to determine the factors that significantly accounted for the variability in driving income. Drivers were mainly composed of married and middle-aged men, majority of whom were high school graduates. Average household size was from 4—5 members with the father—driver as the only earning family member. Income from jeepney driving accounted for over half of the monthly total household income, averaging at P4,039.73. Drivers houses were made of GI roofs, and wooden outer walls. Most of the sample personally owned their housing units but were squatting on other people's lands. Their houses were equipped with electricity for lighting, LPG for cooking, manual pumps for drinking water and exclusive waste—sealed toilets. Food accounted for over 607. of the driving households' expenditures followed by education, utilities, and medical care. Out of their expenditures, the driving households were still able to save less than 10%. of their total incomes. Operator driver households had higher expenditure levels than boundary driver households. On the average, the drivers' total expenditures were higher than the 1996 inflated food and poverty thresholds. Their income-expenditure patterns reveal a discrepancy of P1414.21 between their total household income and total household expenditures which means that drivers' households have higher chances of increasing their savings levels. Driving experience averaged at 16 years. Consisting mainly of boundary drivers, majority of the sample — fueled jeepneys. Striking rounds were mostly done during peak hours (7-9 AM, 11-1 PM, and 4-7 PM) while parking rounds were done during lean hours (9-11 AM and 1-3 PM). Drivers were largely free to choose how long and how often to work in a day or week. They drove for six days weekly and averaged nine hours per day. Passing by 10-16 schools, jeepneys which traversed four routes (Bata-Libertad, Shopping-Libertad, Banago—Libertad , and Mandalagan-Libertad jeepneys) had relatively higher mean incomes than the rest of the sample. Boundary drivers had higher reported boundary fees and lower daily incomes than operator drivers. The sample's average driving income breaks even with the daily poverty threshold for a family of six members. Only 36% had SSS memberships. Drivers largely shouldered the vulcanizing, fuel, association membership fees and traffic violation penalties of utility vehicles while operators largely assumed its expenses for vehicle-related violations, spare parts, repair, and maintenance needs.The subject-respondents considered the small volume of passengers on some routes, the high cost of penalties from traffic violations, the unscrupulous apprehensions of traffic enforcers, the proposed traffic rerouting scheme and the labor—intensiveness of the occupation as some of its most pressing problems. The postulated regression model was determined to be highly significant with an F-computed value of 7.964. The t-test and p- values, likewise, indicated four independent variables ( number of schools passed, the capacity of the vehicle, the number of strikes per day, and the type of driver) to be significant and accounted for about 397. of the variability in driving income.Item Prevalence and risk factors for hypertension and obesity among public utility jeepney and tricycle drivers in Janiauy, IloiloBacallan, Jed Vincent; Caro, Miguel Angelo; Delos Reyes, Fate; Divinigracia, Bert Lorenz; Ehimplar, Annie Rose; Lavente, Hannah Gail; Mallorca, Tracy Roz; Tabañar, Jessa Andrea; Tubeo, Nikki Francheska; Villanueva, Ma. Sharee Lou (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2014-04)A cross sectional study was conducted in Janiuay, Iloilo, involving tricycle drivers and jeepney drivers. The objective of this study was to determine and compare the prevalence and risk factors for hypertension and obesity between public utility jeepney and tricycle drivers in Janiuay, Iloilo. A total of 165 respondents, jeepney (87) and tricycle (78), were measured with an aneroid sphygmomanometer and tape measure to determine the blood pressure and waist-hip ratio. An interview was also conducted to determine occupational factors and lifestyle habits. Results were analyzed through SPSS using Chi-square test, T-test and Odds ratio. The prevalence of hypertension was found to be greater in jeepney drivers (36.80%) compared to tricycle drivers (34.60%). The prevalence of obesity was found to be greater in tricycle drivers (46%) compared to jeepney drivers (45%). There is a significant difference in the occupational risk factors between jeepney drivers and tricycle drivers, years of driving, average trip time, kilometers travelled per day and number of trips per day (p<0.0005). However, working days per week (p<0.08) and working hours per day (p<0.30) showed no significant difference between two populations. The results of the odds ratio showed no significant effect in all lifestyle factors to hypertension and obesity. There is no significant difference in the prevalence of hypertension, obesity, and lifestyle risk factors between jeepney drivers and tricycle drivers. However there is a significant difference in the occupational risk factors between the two driver populations.Item The political dynamics behind the renovation of Felix Gorriceta Jr. Avenue connecting Pavia-Mandurriao and its effects on property holders and PUV operators associationAlbaladejo, Christine Kate; Laude, Jennifer (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2011-03)This study looks into the political dynamics behind the implementation of the policy renovating the Felix Gorriceta Jr. Avenue in Pavia, Iloilo and its effects on two end-users—property holders as represented by Parc Regency, and transportation sector represented by the Leon Jeepney Operators and Drivers’ Association (LEJODA). The interrelationships between various levels of the government in the conceptualization of the infrastructure project is examined. It describes conditions of the area where the road stretches prior to the renovation; identifies the reasons why the policy was pursued; and examines how the policy on renovation affected the end-users. Interviews as well as secondary data were utilized in the study. The initiatives and funding for the project came out of a broader plan to integrate the road to the Iloilo airport from the national government, and subsequently chosen by the provincial government of Iloilo relative to other sites. The local government of Pavia had little role to play in its conceptualization, except for the necessary measures for the full implementation of the said policy. The policy conferred benefits to both end-users.Item Patterns and shifts of the Carriada system of San Remegio, Antique in Western PanayAlera, Geralyn G. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1998-03)This descriptive research identifies the patterns and shifts in the transport and trading practices of the carriada across the southern boundaries between the provinces of Antique and Iloilo. Along with occular observations, interviews were conducted by the researcher with village residents of San Remigio (Antique) to gain insights into the everyday workings of village life. The results reveal that there have been changes in the carriada system explained by changes in the availability of vehicles and animals used and types and levels of productivity of local crops. Another significant factor affecting the development of the carriada were directly relevant to the settings of Barangay Agricula and Barangay Panpanan 1: the population increase in both village. However, the changes in the carriada system did not greatly alter the characteristics of the peasant economy of these areas. Although more people engage in more trade, their incomes/profits are not that substantial to change their life patterns. People still live in houses made of wood, bamboo and nipa, and crops they yield from their farms are just enough for family consumptions. Most residents in the mountain areas still aspire to obtain a living from their farms for generations to come.
