Antifungal activities of lemongrass (Cymbopogon citratus) essential oil -B-cyclodextrin inclusion complex incorporated in commercial fish feeds
Baure, Jiaren G. (Department of Chemistry, College of Arts and Sciences, University of the Philippines Visayas, 2019-06)
During the wet season in the Philippines, fish feeds can be contaminated with mycotoxins, affecting fish production. The addition of essential oil (EO) is one of the ways to prevent this, but it is prone to physical and chemical reactions. Thus, this study aims to encapsulate lemongrass essential oil (LGEO) in B-cyclodextrin (B-CD) to produce an inclusion complex (IC) that can be used as an additive in commercial tilapia feeds to prevent or minimize fungal contamination. The inclusion complex was made using the co-precipitation method and was characterized by Fourier Transform Infrared (FTIR) Spectroscopy. The spectrum was similar to that of citral, a major component of
lemongrass essential oil that is responsible for inhibiting fungi. The antifungal activities of pure and encapsulated LGEO at varying concentrations against Aspergillus species were carried out by the Agar Well Diffusion assay. Results showed that A. flavus was more susceptible in LGEO and IC compared with A. fumigatus. The tested concentration of EO could inhibit both fungi. However, it would take 50% IC to effectively inhibit the growth of both fungi. The stability of the inclusion complex in commercial fish feeds was also evaluated. The feeds were stored in an area with the appropriate conditions that could promote the growth of molds, such as temperature (>27°C), moisture levels (14%), and relative humidity levels (>70%). The results showed that the encapsulated LGEO was effective in extending the shelf life of the feeds and was best observed at a concentration of 5 g kg-1 IC. The oil remained active for nine days, wherein about 10- 40% of the feeds with 5 g kg-1 IC were covered with molds. On the other hand, about 70-100% of the surface of the feeds with essential oil was contaminated with molds after nine days, which indicated that encapsulation of EO was needed to maintain its effectiveness as an antifungal agent.
Locus of control of male adolescents with imprisoned fathers: Its relation to their academic adjustment
Bataan, Arminda A.; Losare, Anna Marie C. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2002-03)
This study sought to determine the kind of locus of control of the respondents and the level of academic adjustment as seen in their grade point averages. The researchers aimed to find out if there exists a relationship between locus of control and academic adjustment of these male adolescents with imprisoned fathers. This study was patterned on a previous research on the relationship between the same variables but this study utilized a different instrument and respondents came from Iloilo province.
Fifteen (15) college students whose fathers were imprisoned at the time that they were enrolled served as respondents of the study. All respondents came from Iloilo, 33% of which are from Iloilo City and the remaining 67% are from the municipalities. Their ages range from 17-24.
Respondents were selected using the snowball method. Respondents were asked to answer the Trice Academic Locus of Control Scale. The scale is composed of 28 items answerable by true or false determined the kind of locus of control of these male adolescents with imprisoned fathers. In addition, the respondents were asked to submit their copy of grades of the previous semester to determine how well they adjust academically.
The computed Pearson Product Moment Correlation is r=0.26 with a rcrit=0.441 at 0.05 alpha. This signifies that indeed there is a significant relationship between locus of control and academic adjustment of male adolescents with imprisoned fathers. However, it revealed a weak positive correlation between locus of control and academic adjustment.
The findings imply that locus of control is not the sole cause or factor for academic adjustment. The cause or source of a well-adjusted academic performance of male adolescents with imprisoned fathers may therefore be attributed to other factors such as economic and social support coming from family and friends. Such factors could even lead to a poor academic performance. Lastly, academic adjustment and locus of control vary among the respondents, which suggest individual differences among them
An analysis of BMPM photojournalism and its impact to Negros Traditional Journalists
Bastian, Liezel Margie Lou S.; Cabarles, Jodhie Mae A.; Idorot, Arnielyn Joanne L. (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 2014-04)
This research is geared towards identifying the visual elements that make BMPM photojournalism as either a catalyst or a threat according to Negros traditional journalists, specifically in determining if the values required for traditional media to become newsworthy be likewise applied to Bayan Mo I-Patrol Mo (BMPM)'s photojournalism when comparatively analyzed. It assesses if Negros traditional journalists are in approval or disapproval of BMPM as a citizen journalism platform especially during Typhoon Yolanda. This study is carried out in order to further understand BMPM's implications, as a social-media based citizen journalism platform, to the society. A content analysis wherein Typhoon Yolanda-related BMPM photos submitted from November 8 up to December 8 are analyzed and a survey answered by Negros Press Club members selected through Systematic Random Sampling were conducted. Content analysis results showed that catalyst visual elements prevail more than its threat counterpart, signifying that traditional news values are dominantly applied in BMPM photos. On the other hand, survey results have shown that Negros traditional journalists viewed that BMPM photojournalism contains visual elements of threat. Furthermore, they disapproved BMPM as a citizen journalism platform because it can reduce the quality of journalism disseminated to the public due to the uncertainty of Bayan Patrollers' lack of formal background in journalism.
Some family-related variables in attitude towards aging among the elderly
Bastareche, Ros Anne T.; Fernandez, Tanya Marie P. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2017-06)
This study investigated the relationship of attitude towards aging with some family- related variables including: perception on spouse's death, perception of social support and satisfaction with family life. A total of 61 (N= 61) male and female, widowed and non-widowed elderlies, was included in the study. The design of the study was descriptive-correlational. Data were analyzed using Spearman’s rho Correlation Coefficient and Mann Whitney U Test with alpha level pegged at 0.05. Results showed that there was a significant difference in attitudes between widowed and nonwidowed elderlies with the latter showing more positive valence. In addition, the elderly’s perception of social support was significantly correlated with their attitudes toward aging. The expected relationship of the elderly’s attitude towards aging and other variables were not supported.
Exposure to sexually violent films: Judgements on domestic violence
Basco, Wendy G.; Gallardo, Bonnie L. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2003-03)
This study aimed to know if exposures to sexually violent films have effect toward judgments on domestic violence victim.
The three hypotheses were: 1) There is a significant effect from gradual exposure to sexually violent films toward judgments on domestic violence victim ; 2) There is a significant effect from sudden exposure to sexually violent films toward judgments on domestic violence victim and 3) There is a significant effect from non-exposure to sexually violent films toward judgments on domestic violence victim . This study is experimental which made use of randomized group design or (between group design). The participants of this study were composed of thirty (30) students of UPV Miag-ao, enrolled in Psychology 101 during the second semester on Academic year 2002-2003. The participants were chosen using the random sampling. They were equally distributed to three (3) treatment groups (2 experimental and 1 control group) with ten (10) participants each group. This research project utilized Rape Myth Acceptance Scale, Acceptance of Interpersonal Violence Scale and Myth on Domestic Violence Scale to measure the judgments of participants toward domestic violence victims. Splices from three films (Friday the 13th Part II, American Psycho and I Spit on Your Grave) were also used. The result of the study F (2,29) = 3.35 p< .05 yielded that there is a significant effect of non-exposure to sexually violent films toward judgments on domestic violence victim.
