title: Synthesis of oleoyl-4-carboxybenzenesulfonamide-quaternized chitosan

description: The objectives of this research were to increase mucoadhesive properties of chitosan and then evaluate for using as mucoadhesive drug carrier. Two mucoadhesive modified chitosans, oleoyl-4-carboxybenzenesulfonamide-N-trimethyl chitosan chloride (OA-4-CBS-TMC), and oleoyl-4-carboxybenzenesulfonamide-chitosan N-(3-chloro-2-hydroxy-propyl) trimethylammonium chloride (OA-4-CBS-CS Quat-188), can be achieved by modification of chitosan with 4-CBS and OA conjugated with TMC or CS Quat-188 using 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDAC) as a coupling agent. The degree of quaternization (%DQ) of TMC and CS Qaut-188 were 18.90% and 24.05%, respectively. The degree of substitution (%DS) of 4-CBS on TMC, 4-CBS on CS Quat-188, OA on 4-CBS-TMC, and OA on 4-CBS-CS Quat-188 were 9.70%, 10.36%, 34.15%, and 37.88%, respectively which calculated by 1H NMR. Periodic Acid Schiff (PAS) colorimetric method was used to study mucin-conjugated polymer bioadhesive strength in the simulated gastrointestinal fluid (pH 1.2 and 6.4). The OA-4-CBS-TMC and OA-4-CBS-CS Quat-188 showed stronger mucoadhesive properties 2.60, 3.05, 1.48, and 1.80-fold than that of unmodified chitosan at pH 1.2 and at pH 6.4, respectively. An easy and stable one step was presented to fabricate self-assembled well-ordered OA-4-CBS-TMC and OA-4-CBS-CS Quat-188 nanofractal hyperbranch. Nanofractal hyperbranch was prepared by only re-dispersing the polymeric compound in distilled water at a concentration of 2.3 mg/mL. The self-assembled nanofractal hyperbranch had diameter in the range of 2-9 µm with a narrow width distribution. Therefore, both OA-4-CBS-TMC and OA-4-CBS-CS Quat-188 could be suitable to use in gastrointestinal tract.

title: Effects of silver nanoparticles on staphylococcus aureus ATCC 25923 and escherichia coli ATCC 25922 protein profiles

description: AgNPs were synthesized by the reductive sodium borohydride (NaBH4) method. Three capping agents (4-styrenesulfonic acid – co – maleic acid (PSSMA), alginate, carrageenan) were used and compared with non-capping agent for characterization of particle properties and antibacterial testing. PSSMA capped AgNPs presented a better antibacterial susceptibility than AgNPs capped with others. The antibacterial activity and mechanism of PSSMA capped AgNPs on Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) were then investigated using proteomics technique. Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) were used for protein pattern observation and protein identification. From the result, the action of AgNPs against S. aureus and E. coli were determined to be bactericidal. SDS-PAGE gels after staining showed different bacterial protein profiles and protein expression between bacteria exposed and unexposed to AgNPs, which was further confirmed by protein identification and gene ontology based on NCBI and UniProt databases. In addition, data analysis and bioinformatics pathways analysis (String software) concluded that the antibacterial mechanism of AgNPs were based on 6 main functions i.e., signal transduction, molecular transport, metabolic process, DNA replication, transcription, and translation.

title: Urban migration within and across border : factors influencing the choices of destination of Cambodian unskilled labor migrants

description: Economic factor is the primary cause of migration; but it does not mean that economic differentials between regions will always determine the destination of migration. Migration sometimes still continues to exist without such a gap. Evidently, many Cambodian unskilled migrant labors chose to move to Phnom Penh rather than abroad, and for the latter, it was to Thailand rather than to South Korea. This was the case despite a higher payroll there than in Phnom Penh. An explanation is that migration is selective, and the degree of selectivity is determined largely by individual socio-economic characteristics. In other words, the migrants tend to consider different possible destinations and choose the one that fits their attributes the most to maximize the benefit, which is not necessary the highest monetary gain. This study investigates the underlying determinants of the choices of destination of Cambodian unskilled labor migrants both internal and cross-border, using primary qualitative data with the total sample of 80 participants who were working in Phnom Penh, the capital of Cambodia and Thailand and retaining a legal status. In general, the study finds the rural population of Cambodia to have been pushed from their area of origin by a combination of multiple economic factors that restricted their income generating activities. Even so, motivation for their first migration mainly came from each individual migrant rather than a third person, particularly the household. The findings are contradictory to the idea that in Asian culture household often encourages labor migrants to take mobility. In contrast, most interviewees denoted that their family attempted to dissuade them from migrating due to the notions of uncertainty and risks of migration resulted from malfunctioning mass media and limited access to technology. Nonetheless, to prevent from falling deeper into grievous form of impoverishment or indebtedness, migration was considered a must rather than just an option. That is to say, migration for Cambodian rural population was apparently a mechanism to ensure their continuous survival instead of a method for extra earning against unfortunate agricultural shocks or crop failure. Ultimately, it is discerned that multiple roles of social connection at the destination in facilitating pre, during, and post successful migration process regularly conclude the decision on migration destination.

title: HOW DOES SELF-RATED HEALTH DIFFER AMONG OLDER MEN AND WOMEN?; EVIDENCE FROM VIETNAM.

description: The rapidly increasing of population aging in Vietnam poses far-reaching impacts on various aspects of older persons’ life, especially their health status. Self-rated health can provide a holistic view of the health status of older population. The data for this study was utilized from a nationally representative survey, Vietnam National Aging Survey (VNAS) conducted in 2011. The sample of this study was restricted to population aged 60 and over. The final analytical sample of this study was 2,549 older persons. The study used descriptive statistics and binary logistic regression to analyze the data. The results indicated that the proportion of reporting poor and very poor health status was higher among women (68.4%) than men (57.0%). Results of the logistic regression analysis showed that, for men, perceived sufficiency of income, alcohol drinking, and chronic diseases were significantly associated with reporting poor health status. For women, besides having the same factors associated with Self-rated health as men, employment status, educational level, place of residence, and region were found to be strongly associated with poor self-rated health. Therefore, health-related programs with regards to gender-based should directly focus on all the factors identified in this paper to improve the overall well-being of the aging population of Vietnam.

title: Verbal autopsy in Vietnam : the degree of agreement on specific cause of death with medical record and families-given cause of death

description: Background: Similar to middle and low-income countries, the accurate of the nationally representative statistics on mortality in Vietnam are deficient because of inadequate routine information systems. There is an effort to solve this problem by introducing the verbal autopsy (VA) method, which is the process of interviewing caregivers on the circumstances leading to death to assess the cause of death (CoD). Studies on CoD are relatively new and scarce in the Vietnamese context given its mortality registration system. In this regard, the reliability study on the VA mortality data is essential for the improvement of data quality on CoDs. This study is designed to evaluate the consistency of the VA derived CoD (VACoD) with the medical record (MCoD) and Families-Given CoD (FGCoD) in three provinces in Vietnam. Methods: This study assesses the consistency of the VACoD in three provinces of Vietnam (Hochiminh City, Binhduong Province and Lamdong Province). The data include all of death cases occurring between 1st January 2008 and 31st December 2009 in selected areas which had verbal autopsy (VA) records together with medical records or death certificates. Furthermore, the study investigates factors that relate to the agreement between these approaches by applying multivariate estimations. Results: Between 2008 and 2009, there were 4,672 VA interview records in these provinces, in which 252 cases had medical records, where 64 cases of these deaths occurred in hospital. There were 3,166 cases that had death certificates. We found that VACoD agreed with MCoD about 56% of 64 deaths. For specific causes of cardiovascular diseases occupied the highest proportion of agreement (90%). With regards to the agreement between VACoD and FGCoD, transport accident and senility represent the highest proportion of agreement (92.6%). In total, nearly a half of 3,166 death cases (47.2%) from VA agreed with those derived from death certificates in terms of causes of death. Moreover, our findings suggest that VA is robust to time after death. We found that the recall period had no effect on the agreement given the duration of the recall period in our study ranged from 9 to 24 months. Conclusion: VA agreed moderately with MCoD and FGCoD in determining the underlying causes of death. We recommend further investigations of the effect of characteristics of respondents on the level of agreement given better data in the future. We hope that our study, albeit small, provide useful results that will stimulate further works for strengthening the national cause-specific mortality statistics in Vietnam and other developing countries alike. Keywords: Cause of death, verbal autopsy, consistency, agreement, medical record, Families-Given cause of death, Vietnam.

title: WOMEN’S EDUCATION AND FERTILITY AND CHILD MORTALITY EVIDENCE FROM VIETNAM 1989, 1999, AND 2009

description: In this thesis, I aim at investigating whether the variation in education both over time and across regions in Vietnam can explain the variation in the Vietnamese fertility and child mortality. Although a number of quantitative studies on the association between fertility and education have been done, there is an absence of a quantitative insight based on the evidence from Vietnam, where fertility, child mortality and education has undergone significant changes. To do so, the thesis uses the female individual-level data from the sample of the Vietnamese Population and Housing Census from the years 1989, 1999, and 2009, provided by IPUMS. In this thesis, fertility measure is based on the number of children the individual has ever born, child mortality is estimated by the number of child death, and education is measured as both levels and years. Using separate cross sectional analysis for each year, the results show that there is indeed an inverse relationship between educational and fertility and in Vietnam. The results also show the vital role of mothers' schooling on child survival. Interestingly, the magnitudes of the influence of mother’s education on both fertility and child death fall over time, possibly suggesting that mother’s education has a stronger relationship with fertility and child survival under the situation when the economy is less developed.

title: Single Motherhood in Vietnam and the Disadvantages in the Living Condition

description: This thesis complements extant studies of single motherhood and its related living condition in the Vietnamese context that only exist in qualitative research methods. It also provides a complement analysis to the existing study by providing evidence from a developing country to a literature that is dominated by evidence from developed countries. The research is based on the individual-level sample of the Population and Housing Census from the years 1999 and 2009, provided by IPUMS International Project. Generally, the results on average indicate that single-mother household is more likely to face more difficulty in living conditions regarding home ownership and having durable goods, than two-parent family. It is clear that two-parent families are at least twofold more likely to have both home ownership and durable goods than single mother families. Moreover, single mothers who are a household head, who lives with only children face more difficulty in living condition indicated by dwelling ownership, basic amenities and durable goods than single mother who are not a household head, who live with other adults and mothers from two parent families. In addition, single mothers who have separate and divorce statuses have more difficulty in terms of home ownership compared with other types single mothers after marital dissolution. In stark contrast, single mothers who have single status have more difficulty in terms of basic amenities and durable goods compared with other kinds of single mothers.

title: Household type of fuel and low birth weight in newborns in Zimbabwe : findings from the 2014 multiple indicator cluster survey

description: There are relatively few studies on the association between type of fuel used in the kitchen and birth weight; and findings are inconsistent. The aim of this study was to further investigate whether there is association between the type of fuel used in a household and low birth weight in newborns. Secondary data from the Zimbabwe Multiple Indicator Cluster Survey 2014(ZMICS2014) was analyzed. From 3910 children who were born during the two years prior to the survey, only 3221 were weighed at the time of their birth. Bivariate and multivariable logistic regression analyses were used to assess associations between type of fuel in household and low birth weight. In bivariate analysis, the odds ratio of giving low birth weight baby was 1.17 times higher in the mothers from households that use biomass, (OR: 1.17, 95% CI: 0.88, 1.57, P=0.281) in comparison to the reference group. After adjusting, for household socio-demographic, maternal and fetal characteristics this weak positive, non-significant association persisted, (OR: 1.17, 95% CI: 0.85, 1.61, P=0.342). When women’s perception of size of their babies at birth, a variable that exists for most of the children was used instead of the birth weight a statistically significant association was observed between the use of biomass fuel and low birth weight, (OR: 1.33, 95% CI: 1.04, 1.68, P=0.021). The association between use of biomass fuel and birth weight was not significant in any of the analyses. At the same time, there was a positive, significant association between biomass fuel use and small size of the baby by the mother’s perception. Also, among mothers for whom birth weight was available, mother’s perception of the baby’s size at birth was significantly associated with birth weight. On balance, an association between biomass fuel use and low birth weight in Zimbabwe cannot be ruled out, even though no significant association was observed in this study. Further research is clearly needed on this important topic.

title: Separation of oily emulsion by flotation and coalescer processes for wastewater treatment

description: The objective of this work was to study the separation of the stable oily emulsion by coalescer and flotation processes. The commercial Castrol Cooledge BI cutting oil was applied for synthesizing the oily wastewater since it can easily form a stabilized emulsion with water. The coalescer experiments were conducted by using polypropylene media with different shapes including granule, fiber, and tube. Effects of emulsion flow velocity and bed height as well as the bed packing were considered. For the flotation, both the dissolved air flotation (DAF) and the induced air flotation (IAF) processes in the pilot scale were employed for the emulsion separation with the addition of aluminium sulfate (Al2(SO4)3) as a coagulant. Influences of operating conditions on the separation efficiency were investigated.The results indicated that the prepared emulsion was highly stable suggested by its small droplet sizes and high negative zeta potential. The emulsion was partly separated by the coalescer with the highest efficiency of 44% from the 10 cm bed of tubular polypropylene with 2 cm/s flow velocity. In the case of the separation by flotation, the highest efficiency of 85% can be achieved from both DAF and IAF. However, the separation by flotation was ineffective without the coagulation. Therefore, the destabilization of the cutting oil emulsion by aluminium sulfate was further investigated. The main destabilization mechanism was the sweep flocculation occurred at the Al3+ concentration of 1.0 mM and pH of 6.5 – 7.5, where solid flocs can be observed. At lower Al3+ dosage, the destabilization was inefficient suggesting that only droplet coalescence was insufficient for the separation. The flocs were analyzed for their chemical composition and crystalline structure to confirm the formation of aluminium hydroxide (Al(OH)3) that plays a role in the sweep flocculation. Furthermore, the results from the bench scale flotation carried out by the Flottatest were correspondent to those obtained from the pilot scale experiments. The addition of coagulant was needed for the effective separation. However, it was also found that the increase of Al3+ dosages further the 1.0 mM was unable to enhance the separation efficiency. Finally, the interactions of droplet-bubble and floc-bubble were observed in the special made observation cell. No interaction between oil droplets and a bubble can be seen contrasting with the case of oil flocs, which can attach on the bubble surface. This affirmed the difference between the separation of cutting oil emulsion by flotation with and without the formation of flocs.

title: The pattern and determinants of living arrangement among elderly in Vietnam, 2011

description: Background: living arrangement plays an important role for the well-being of older people, especially in Vietnam, where the responsibility to take care of the elderly rest largely on the family. Given the context that the population in Vietnam is aging rapidly, any changes related to living arrangement of the elderly may take it tolls on the government and society. Therefore, study related to living arrangement is important. In Vietnam, numbers of studies regarding living arrangement has increased slightly over the past decades but mostly are descriptive studies and few studies explored the determinants of living arrangement. In addition, very few studies explored the children’s characteristics as a component of the determinants of living arrangement among the elderly.Objectives: this study describes the patterns of living arrangements of the elderly and examines the determinants of living arrangements among the elderly in a greater depth compared to the previous studies in Vietnam.Methods: data came from a national-representative survey for the elderly in Vietnam in 2011. Logistic regression were applied to explore the factors affecting living with children versus living with others. Multinomial logistic regression were used to examine the factors associated with various types of living arrangement, which include living with children, living alone, living with spouse only and living with other people.Result: the finding reveals that living in the South or in urban area, having unmarried children or married son resulted in higher the odds of living with children. While gender, education, home ownership as well as employment status of children correlated with higher risk of living alone, living with spouse only and living with other people.
