THE ASEAN-5 FUTURE CURRENCY: MAASTRICHT CRITERIA
In this recent decade, many of the economists and policymakers attempted to investigate the suitability of the East Asian region to form a currency union and based on the European countries experience as a benchmark. This study aims to investigate the long-run real convergence in GDP per capita growth among Malaysia, Thailand, Singapore, Indonesia, and the Philippines, over 1978 to 2004. The Dickey-Fuller (DF) and Augmented Dickey-Fuller (ADF) unit root tests were conducted at first difference of GDP per capita for each country; the results demonstrated that all countries GDP per capita are stationary at first difference. The results of the Bound Testing Approach (Auto-Regression Distributed Lag (ARDL)) indicated that there is a long run relationship between variables in the Maastricht Criteria. The results showed that interest rate, inflation rate and the debt ratio experience that negative relationship to the GDP per capita. However, the exchange rate and surplus (or deficit) ratio shown the positive related to the GDP per capita. Therefore, the findings showed the ASEAN 5 countries have fulfilled the Maastricht Criteria with consistent to expected sign(s) except for Singaporeâ exchange rate and Indonesiaâs debt ratio. Hence, those ASEAN 5 countries in this study have potential to form a single currency.Monetary Union (MU), Bound Test (ARDL), Maastricht Criteria, Single Currency
Distribution of serotonin (5-HT) and dopamine (DA) on digestive tract of red palm weevil larva, Rhynchophorus ferrugineus (Coleoptera: Dryophthoridae)
The red palm weevil (RPW), Rhynchophorus ferrugineus (Coleoptera: Dryopthoridae) is a well-known deadly pest of palmae tree worldwide. The larvae of RPW is the most destructive stage of its life cycle and caused great economic lost to palm tree plantation for example the coconut tree plantations. In this study, we focused on detection of two important biogenic amines, serotonin (5-HT) and dopamine (DA) that play important roles in the regulation of the digestive tract of this insect. Immunohistochemistry analysis has been carried out on the cross-sectioned tissue of three different parts of the digestive tract; foregut, midgut and hindgut. 5-HT receptor for serotonin and D1 receptor for dopamine were chosen for chromogenic detection of the biogenic amine. The distribution of 5-HT can be detected at the plasma membrane, basement membrane and cytoplasm of the cell for the whole guts except at the midgut cell. While DA can only be detected at the basal membrane of the gut cell for the most part of the gut. Further study could be done to find a possible solution in controlling the survival of RPW by understanding the roles of the biogenic amine in controlling and modulating the mechanism of absorption and digestion of the digestive tract
Morphology and histology of reproductive organ and first screening of wolbachia in the ovary of red palm weevil, Rhynchophorus ferrugineus (coleoptera: dryophthoridae)
This study was conducted to assess intracellular bacteria Wolbachia in the ovaries of female Red Palm Weevil (RPW), Rhynchophorus ferrugineus from three populations in Malaysia by means of PCR using wsp- specific primer. The morphology and histology of ovary of RPW were also studied and examined by stereo microscope LEICA EZ4 HD that was equipped with LAS EZ software and light microscope Zeiss Axio Scope with iSolutionLite software respectively. We found that the adult female had two pairs of ovaries, lateral oviduct, common oviduct, bursa copulatrix, spermatheca and vagina. Histological study of the ovariole revealed that it is categorised under polytrophic ovariole. The ovariole is divided into four regions, the terminal filament, the germarium, the vitellarium and the stalk or calyx. Besides, the infection status showed that all three populations were not infected with Wolbachia. Our result suggests that no infection of Wolbachia in RPW reproductive system
Health seeking behaviour of parents of burned children in Bangladesh is related to family socioeconomics
Objective: The study was design to explore the health seeking behaviour of Bangladeshi parents for their children during burn injuries.
Methods: A population-based cross-sectional survey was conducted between January and December 2003 in Bangladesh. Nationally representative data were collected from 171,366 rural and urban households comprising of a total population of 819,429, including 351,651 children of 0â18 years. Mothers or heads of households were interviewed with a structured questionnaire in obtaining the information.
Results: About sixty percent parents seek health care from unqualified service providers for their children during a childhood burn injury. Educated and the higher income groups parents choose qualified service provider at significantly higher rate compared to illiterate and poor. Higher proportion of parents of urban residence chooses qualified service provider compared to rural. No significant difference of health seeking behaviour of parent in choosing care provider was found in relation to sex of the children.
Conclusion: Education, economic condition and place of residence were found as the contributory factors in choosing service provider. Education to the parents can contribute in changes in health seeking behaviour which ultimately contribute in reducing morbidity and mortality from childhood burn injuries. Including parent's education a national burn prevention program needs to be developed to combat the devastating child injury, burn
Consequences of childhood burn: Findings from the largest community-based injury survey in Bangladesh
In terms of morbidity and disability, burn is a major public health problem throughout the
world, especially in low-income countries. It causes long-term disability and remains as a
health, social and economic burden. A population-based survey was conducted in Bangladesh between January and December 2003. Nationally representative data were collected
from 171,366 rural and urban households comprising of a total 819,429 population, which
included 351,651 children under 18 years of age. Mothers/head of households were interviewed with a structured instrument. The objective of this paper is to determine the
consequences of childhood burn at social and economic levels in Bangladesh.
In the survey, 1013 children were found with different degrees of burn in the preceding 1
year. Among them 20 children were permanently disabled. The rate of permanent disability
was found to be 5.7 per 100,000. The average loss of school days was found to be about 21
days. More than two-thirds of the burn victims required assistance in their daily activities
for different durations of time. More than 7% of the children required hospitalisation for
their burns. The rate of hospitalisation was 21.9 per 100,000; the average duration of hospital
stay was 13.4 days. The highest duration (40 days) of hospital stay was found among girls 10â
14 years old. The highest expenditure for the treatment was also found in this age group. The
average direct expenditure incurred by a family for treatment of severe burn was determined to be 50 a month.
Burn is a devastating injury among all childhood injuries with significant additional
economic consequences beyond the medical, pain, and suffering issues. Developing a
national prevention program should be an immediate public health priority
Evaluating the effect of chlorpheniramine on patch test reactions amongst eczema patients sensitised to nickel
Discontinuing antihistamines for patch testing (PT) in allergic contact dermatitis
(ACD) is more conventional than evidence based. Data suggests that non-sedating
antihistamines do not interfere with PT. Investigating the effects of sedating
antihistamines are more relevant as these are recommended for eczema. We aimed
to evaluate the effect of chlorpheniramine on PT, to determine the prevalence of
nickel sensitization and common sensitizing allergens. An open labeled cohort study
was conducted at two dermatology clinics. Patients indicated for PT underwent
standard protocol where antihistamines were discontinued. Patients sensitised to
nickel were subjected to a second nickel PT while taking chlorpheniramine. Results
were evaluated using the North American Contact Dermatitis Research Group
(NACDRG) score, a Mexameter measured erythema and pruritus was assessed
using a visual analogue score. A total 82 patients were recruited, 28 (34.1%) were
sensitised to nickel. The mean age was 40 ± 17.7 years with 22(26.8%) males and
60 (73.2%) females. Indications for PT included suspected ACD (57.3%), hand
and feet eczema (34.1%) and severe eczema with suspected superimposed ACD
(6.1%). The commonest sensitizing allergens were methyldibromoglutaronitrile
(40.2%) nickel sulphate (34.1%), potassium dichromate (29.3%) and formaldehyde
(24.4%). A second PT was performed on 23 patients. There was no difference in the
NACDRG score with chlorpheniramine or without chlorpheniramine (p=0.968).
Pruritus score was reduced by 1.39 ± 2.9, p=0.031 with chlorpheniramine. The
degree of erythema was 611.46 ± 21.59 with chlorpheniramine versus 613.87 ±
27.5 without chlorpheniramine, p=0.671. Chlorpheniramine did not affect PT
based on clinical and objective scorings. It has the additional benefit of reducing
test-induced itch

Preparation of reinforced hydroxyl terminated liquid epoxidized natural rubber nanocomposite by grafting of graphene oxide
In this research, liquid epoxidized natural rubber (LENR) with active end group which known as hydroxyl terminated liquid epoxidized natural rubber (HTLENR) has been synthesized via oxidative degradation method in the presence of cobalt acetylacetonate (CAA) and sodium borohydride (NaBH4). The conversion of LENR to HTLENR is vital to fully utilise the great properties of this liquid rubber and enable for further chemical modification. The molecular weight of the prepared HTLENR were confirmed using gel permeation chromatography (GPC) and weight average molecular weight (MW) of HTLENR revealed a slight decrease in comparison to MW of LENR at one hour reaction. Whilst the structure of LENR and HTLENR were studied using Fourier transform infra-red (FTIR) and neutron magnetic resonance (NMR). Subsequently graphene oxide (GO) has been inserted onto HTLENR backbone via grafting method. The efficiency of grafting was confirmed using Fourier transform infrared (FTIR) analysis. HTLENR/GO nanocomposite prepared is important to be serve as a potential toughening agent which can be used in various applications such as aerospace, structural and automotive
Key Food Hygiene Behaviors to Reduce Microbial Contamination of Complementary Foods in Rural Bangladesh
Microbial contamination of complementary foods puts young children at risk of developing intestinal infections and could be reduced by improved handwashing and food hygiene practices. We aimed to identify which promoted food hygiene practices are associated with reduced complementary food contamination in a rural population in Bangladesh. We collected cross-sectional data on reported and observed maternal food hygiene behaviors and measured Escherichia coli counts as an indicator of microbial contamination in complementary food samples from 342 children of women enrolled in the Food and Agricultural Approaches to Reducing Malnutrition trial in Sylhet, Bangladesh. We used multivariable logistic regression to examine associations of food hygiene behaviors with food contamination. Approximately 46%of complementary food samples had detectable levels of Escherichia coli. Handwashing with soap at critical times and fresh preparation of food before feeding were strongly associated with reduced odds of food sample contamination (odds ratio [OR]: 0.8, 95% confidence interval [CI]: 0.6-0.9 and OR: 0.3, 95% CI: 0.1-0.7, respectively); in contrast, there was no or only weak evidence that reheating of stored food, safe food storage, and cleanliness of feeding utensils reduced contamination. Reduction in food contamination could be more than halved only when several food hygiene behaviors were practiced in combination. In conclusion, single food hygiene practices showed limited potential and a combined practice of multiple food hygiene behaviors may be needed to achieve a substantial reduction of complementary food contamination
