This paper examines the influence of maternal education on the acceptance of tetanus toxoid vaccine, using data from two villages in rural Yogyakarta, Indonesia. Maternal education results in increased tetanus toxoid uptake. Irrespective of the level of formal education, correct knowledge of the function of tetanus toxoid is positively associated with the probability of using the vaccine. It is therefore recommended that health education campaign be run to provide correct information on the importance of tetanus toxoid. This study can be used as a model for health programmes in other population with low levels of women education.
Key words: Neonatal tetanus, maternal education, tetanus toxoid, binomial logistic regression, multinomial logistic regression.

The Malacca Straits is located between Peninsula Malaysia and Sumatra Island. This investigation used equation of motion (Navier-Stokes equation) with the following driving forces: tides, wind of National Centers for Environmental Prediction (NCEP) for year of 2007, salinity and temperature. The equation of motion was solved by means of Hamburg Shelf Ocean Model (HAMSOM). The results for both southwest and northeast monsoon were explained and discussed. The simulation results both for February and August 2007 were relatively similar. Current surface simulation in the Malacca Straits agrees well with the current pattern of previous works. The magnitude of current was between 10-70 cm/s to the northwest. While at the layer 30-50 m in the Malacca Straits, the currents have the magnitude of 10-30 cm/s towards northwest. For the bottom current, the current speed was 0-20 cm/s towards northwest. For the surface and 30-50 m layer, generally the current magnitudes were greater in February compared to those in August. While for the bottom layer, the current magnitudes between February and August were relatively the same.
Biomass burning is one of the main sources of air pollution in South East Asia, predominantly during the dry period between June and October each year. Sumatra and Kalimantan, Indonesia, have been identified as the regions connected to biomass burning due to their involvement in agricultural activities. In Sumatra, the Province of Riau has always been found to have had the highest number of hotspots during haze episodes. This study aims to determine the concentration of five major pollutants (PM10, SO2, NO2, CO and O3) in Riau, Indonesia, for 2006 and 2007. It will also correlate the level of air pollutants to the number of hotspots recorded, using the hotspot information system introduced by the Malaysian Centre for Remote Sensing (MACRES). Overall, the concentration of air pollutants recorded was found to increase with the number of hotspots. Nevertheless, only the concentration of PM10 during a haze episode is significantly different when compared to its concentration in non-haze conditions. In fact, in August 2006, when the highest number of hotspots was recorded the concentration of PM10 was found to increase by more than 20% from its normal concentration. The dispersion pattern, as simulated by the Hybrid Single Particle Lagrangian Integrated Trajectory Model (HYSPLIT), showed that the distribution of PM10 was greatly influenced by the wind direction. Furthermore, the particles had the capacity to reach the Peninsular Malaysia within 42 hours of emission from the point sources as a consequence of the South West monsoon.

Linear time series models are not able to capture the behaviour of many financial time series, as in the cases of exchange rates and stock market data. Some phenomena, such as volatility and structural breaks in time series data, cannot be modelled implicitly using linear time series models. Therefore, nonlinear time series models are typically designed to accommodate for such nonlinear features. In the present study, a nonlinearity test and a structural change test are used to detect the nonlinearity and the break date in three ASEAN currencies, namely the Indonesian Rupiah (IDR), the Malaysian Ringgit (MYR) and the Thai Baht (THB). The study finds that the null hypothesis of linearity is rejected and evidence of structural breaks exist in the exchange rates series. Therefore, the decision to use the self-exciting threshold autoregressive (SETAR) model in the present study is justified. The results showed that the SETAR model, as a regime switching model, can explain abrupt changes in a time series. To evaluate the prediction performance of SETAR model, an Autoregressive Integrated Moving Average (ARIMA) model used as a benchmark. In order to increase the accuracy of prediction, both models are combined with an exponential generalised autoregressive conditional heteroscedasticity (EGARCH) model. The prediction results showed that the construct model of SETAR-EGARCH performs better than that of the ARIMA model and the combined ARIMA and EGARCH model. The results indicated that nonlinear models give better fitting than linear models.
We investigated the spatial and temporal patterns of Cautires diversification on the Malay Peninsula and Sumatra to understand if the narrow and frequently dry Malacca Strait separates different faunas. Moreover, we analyzed the origin of Cautires in Malayan and Sumatran mountains. We sampled 18 localities and present the mtDNA-based phylogeny of 76 species represented by 388 individuals. The phylogenetic tree was dated using mtDNA evolution rates and the ancestral ranges were estimated using the maximum likelihood approach. The phylogeny identified multiple lineages on the Malay Peninsula since the Upper Eocene (35 million years ago, mya) and a delayed evolution of diversity in Sumatra since the Upper Oligocene (26 mya). A limited number of colonization events across the Malacca Strait was identified up to the Pliocene and more intensive faunal exchange since the Pleistocene. The early colonization events were commonly followed by in situ diversification. As a result, the Malacca Strait now separates two faunas with a high species-level turnover. The montane fauna diversified in a limited space and seldom took part in colonization events across the Strait. Besides isolation by open sea or a savannah corridor, mimetic patterns could decrease the colonization capacity of Cautires. The Malay fauna is phylogenetically more diverse and has a higher value if conservation priorities should be defined.
Facial anthropometric data has significant ethnic variation. East Asia, comprised of fourteen countries, represents a significant proportion of the global population. This systematic review presents the facial anthropometric data collected from these countries. The systematic review was conducted in accordance with PRISMA guidelines. An electronic search of the MEDLINE database returned 3054 articles. Twenty articles were considered eligible for inclusion. Nine studies were conducted in China, 1 in Indonesia, 2 in Japan,3 in Korea, 4 in Malaysia, and 1 was a multicentre study conducted in China, Japan, Thailand, and Vietnam. Qualitative and quantitative parameters were extracted from the20 studies. No data was found for the other East Asian countries. There is a paucity of facial anthropometric data for East Asian countries despite their high burden of craniofacial anomalies and a strong demand for cosmetic facial surgery, both of which would benefit from the collection of robust craniofacial norms. It is in the interest of both the craniofacial surgeon and the East Asian patient to collect baseline facial anthropometric data for this population.
Malaysia was ranked at 148 by World Health Organization (WHO) in suicide statistic for 2012, where males had a higher
tendency to commit suicide, recording a 4.7 per 100,000 in comparison to female (1.5 per 100,000). As hanging is one of
the most common methods to commit suicide, this retrospective study was conducted to observe the incidence of suicide
by hanging in Klang Valley from four different hospitals. The current study is conducted to provide local database of
suicide occurrence by hanging in Klang Valley. A total of 893 suicide cases by hanging from 2007 to 2016 were recorded
from post mortem records and analysed. Suicide rates in Klang Valley showed a rising trend from 2007 to 2016. Males
from age group 30 to 34 years old and females from 20 to 24 years old have the highest number of suicide fatalities
compared to other age groups. Meanwhile, fatalities from the age group of 10 to 14 years old and 80 years old and above
showed similar result which is only 7%. 78% of the fatalities were recognized as Malaysian and half of them were Indian.
Majority of the victims/cases (45%) who committed suicide by hanging are of Hindu religious denomination. Non-citizen
in Malaysia that have the highest suicide rates were from Nepal, Indonesia and Myanmar. Victims also committed suicide
more during the day and the peak hours being at 12.00 pm to 5.59 pm.
A strategic multilateral dialogue related to biosecurity risks in Southeast Asia, established in 2014, now includes participants from Singapore, Malaysia, Indonesia, Thailand, Philippines, and the United States. This dialogue is conducted at the nonministerial level, enabling participants to engage without the constraints of operating in their official capacities. Participants reflect on mechanisms to detect, mitigate, and respond to biosecurity risks and highlight biosecurity issues for national leadership. Participants have also identified factors to improve regional and global biosecurity, including improved engagement and collaboration across relevant ministries and agencies, sustainable funding for biosecurity programs, enhanced information sharing for communicable diseases, and increased engagement in international biosecurity forums.
The study was a Quasi experimental two group pre-and post- experimental design. It involved 32 samples at both experimental and control groups. This research was conducted to examine the effect of Guided Imagery on depression among male inmates. Subjects in the experimental group were asked to practice Guided Imagery in group for 10 sessions three times a week over 4 weeks of treatment period. Subjects from the control group participated in daily activities. Due to ethical consideration, following the completion of this study, however, the subjects in the control group were given Guided Imagery exercises as to reduce their depression signs and symptoms. The data were collected from the prisoners at Correctional Institution Sukamiskin Bandung Indonesia, from August to September 2014. Guided Imagery demonstrated a statistically significant reduction in depression (p=0.041) on the experimental group compared with the control group. Guided Imagery is a powerful, simple and economic intervention to reduce depression symptoms. The study found that the experimental group experience less depression than the control group. This study can be applied to other correctional institutions to reduce depression among prison inmates. Further studies are recommended to explore the effectiveness of guided imagery on depression among male inmates.
Analysis of relationship between sea surface temperature (SST) and Chlorophyll-a (chl-a) improves our understanding on the variability and productivity of the marine environment, which is important for exploring fishery resources. Monthly level 3 and daily level 1 images of Moderate Resolution Imaging Spectroradiometer Satellite (MODIS) derived SST and chl-a from July 2002 to June 2011 around the archipelagic waters of Spermonde Indonesia were used to investigate the relationship between SST and chl-a and to forecast the potential fishing ground of Rastrelliger kanagurta. The results indicated that there was positive correlation between SST and chl-a (R=0.3, p<0.05). Positive correlation was also found between SST and chl-a with the catch of R. kanagurta (R=0.7, p<0.05). The potential fishing grounds of R. kanagurta were found located along the coast (at accuracy of 76.9%). This study indicated that, with the integration of remote sensing technology, statistical modeling and geographic information systems (GIS) technique were able to determine the relationship between SST and chl-a and also able to forecast aggregation of R. kanagurta. This may contribute in decision making and reducing search hunting time and cost in fishing activities.
Over the years, maximum likelihood estimation and Bayesian method became popular statistical tools in which applied to fit finite mixture model. These trends begin with the advent of computer technology during the last decades. Moreover, the asymptotic properties for both statistical methods also act as one of the main reasons that boost the popularity of the methods. The difference between these two approaches is that the parameters for maximum likelihood estimation are fixed, but unknown meanwhile the parameters for Bayesian method act as random variables with known prior distributions. In the present paper, both the maximum likelihood estimation and Bayesian method are applied to investigate the relationship between exchange rate and the rubber price for Malaysia, Thailand, Philippines and Indonesia. In order to identify the most plausible method between Bayesian method and maximum likelihood estimation of time series data, Akaike Information Criterion and Bayesian Information Criterion are adopted in this paper. The result depicts that the Bayesian method performs better than maximum likelihood estimation on financial data.
As part of our study, we reviewed the report published in BMC-Oral Health, titled "An assessment of the impacts of child oral health in Indonesia and associations with self-esteem, school performance and perceived employability" by Maharani et.al, 2017. We noted a plausible error in the interpretation of results in the report and re-examined the published data. Contradictory to the published report, our analysis showed no evidence for the relationship between toothache and poor school performance. Significant relationship was only found between plaque accumulation and school performance. We argued that the error may have originated from an unclear objective and misclassification of school performance variable before applying statistical test to address the objective of this study.
Parasitological and serological investigations for lymphatic filariasis were performed on 450 immigrants detained at the lmmigration Centre at Semenyih, Selangor, West Malaysia. The country of origin of these immigrants were Indonesia, The Philippines, Myanmar, Bangladesh, India and Pakistan. Brugia malayi adult worm homogenate (BmAH) antigen was used for the detection of antiifilarial IgG. A monoclonal antibody-based ELISA (MAb.XC3-ELISA) specific for filarial circulating antigens and non-phosphorylcholine reactive was used to detect antigenemia in these immigrants. Parasitologically 67 (14.89 %) were positive for W. bancrofti and 54 (12.0%) for Brugia malayi. Serologically 63% had antifilarial IgG titre to the BmAH antigen. While Bancroftian filariasis is now unknown in Peninsular Malaysia, the potential of it to be reintroduced into Peninsular Malaysia by the immigrant population is discussed. KEYWORDS: Lymphatic filariasis, immigratits, antifilarial IgG, antigenemia
Malaysia has been swamped by migrant workers from nearby countries like Indonesia, Phillipine and also Bangladesh since 1980's. The main pulling forces which motivated them to migrate to Malaysia are better economy, political stability and religious freedom in Malaysia. Another way of classifying migration pattern is to divide it into push and pull migration or a combination of the two. Pull migrants are those who migrate to obtain better economic opportunity while push migrants are those who try to run away from being prosecuted or due to fear of political and religious suppression. Whatever the push and the pull factors, they are bound to encounter some acculturation challenges. This will inevitably produce certain psychological sequelae. Therefore, the main aim of this study is to determine the point prevalence of psychiatric morbidity experienced by the migrant population. The psychological impact of push and pull migrations is fundamentally distinct. There were significant numbers of migrants admitted to University Hospital psychiatric units who suffered from psychological distress and para suicide. The reasons for these problems are multi-faceted. Hence, another purpose of this study was to investigate factors which make them to be at risk of developing psychiatric morbidity. The findings of this study can be used as a basis for making recommendations to the government of the rationale to include psychological assessment as one of the important components in the pre-employment selection criteria.
The global demand for palm oil has grown rapidly over the past several decades. Much of the output expansion has occurred in carbon- and biodiversity-rich forest lands of Malaysia and Indonesia (M&I), contributing to record levels of terrestrial carbon emissions and biodiversity loss. This has led to a variety of voluntary and mandatory regulatory actions, as well as calls for limits on palm oil imports from M&I. This paper offers a comprehensive, global assessment of the economic and environmental consequences of alternative policies aimed at limiting deforestation from oil palm expansion in M&I. It highlights the challenges of limiting forest and biodiversity loss in the presence of market-mediated spillovers into related oilseed and agricultural commodity and factor markets, both in M&I and overseas. Indeed, limiting palm oil production or consumption is unlikely to halt deforestation in M&I in the absence of active forest conservation incentives. Policies aimed at restricting palm oil production in M&I also have broader consequences for the economy, including significant impacts on consumer prices, real wages, and welfare, that vary among different global regions. A crucial distinction is whether the initiative is undertaken domestically, in which case the M&I region could benefit, or by major palm oil importers, in which case M&I loses income. Nonetheless, all policies considered here pass the social welfare test of global carbon dioxide mitigation benefits exceeding their costs.
The Heart of Borneo initiative has promoted the integration of protected areas and sustainably-managed forests across Malaysia, Indonesia, and Brunei. Recently, however, member states of the Heart of Borneo have begun pursuing ambitious unilateral infrastructure-development schemes to accelerate economic growth, jeopardizing the underlying goal of trans-boundary integrated conservation. Focusing on Sabah, Malaysia, we highlight conflicts between its Pan-Borneo Highway scheme and the regional integration of protected areas, unprotected intact forests, and conservation-priority forests. Road developments in southern Sabah in particular would drastically reduce protected-area integration across the northern Heart of Borneo region. Such developments would separate two major clusters of protected areas that account for one-quarter of all protected areas within the Heart of Borneo complex. Sabah has proposed forest corridors and highway underpasses as means of retaining ecological connectivity in this context. Connectivity modelling identified numerous overlooked areas for connectivity rehabilitation among intact forest patches following planned road development. While such 'linear-conservation planning' might theoretically retain up to 85% of intact-forest connectivity and integrate half of the conservation-priority forests across Sabah, in reality it is very unlikely to achieve meaningful ecological integration. Moreover, such measure would be exceedingly costly if properly implemented-apparently beyond the operating budget of relevant Malaysian authorities. Unless critical road segments are cancelled, planned infrastructure will fragment important conservation landscapes with little recourse for mitigation. This likelihood reinforces earlier calls for the legal recognition of the Heart of Borneo region for conservation planning as well as for enhanced tri-lateral coordination of both conservation and development.
Background: Breast cancer is the most common cancer type in women not only in world but also in Malays ethnicity between Malaysia and Indonesia. Breast cancer has varying incidence in every country, but genetic factor by family history influence the incidence of breast cancer. This systematic review and meta-analysis was performed to determine family history of breast cancer and breast cancer risk between Malays ethnicity in Malaysia and Indonesia.
Methods: This meta-analysis was conducted on published research articles on family history of breast cancer and breast cancer risk between Malays ethnicity in Malaysia and Indonesia published between Jan 1999 and Jul 2018 in the online article databases of PubMed, ProQuest and EBSCO. Pooled odds ratios (OR) were calculated with fixed and random-effect models. Publication bias was visually evaluated by using funnel plots and statistically assessed through Egger's and Begg's tests. Data were processed using Review Manager 5.3 (RevMan 5.3) and Stata version 14.2 (Stata Corporation).
Results: We reviewed 1123 articles. There are 10 studies with number of samples 4511 conducted a systematic review and continued with Meta-analysis of relevant data. The results showed significant association between family history of breast cancer with breast cancer risk in Malays ethnicity in Malaysia and Indonesia (OR = 3.34 [95% CI 2.68-4.15, P<0.00001]). There was not significant publication bias for studies included in family history of breast cancer and breast cancer risk in Malays ethnicity in Malaysia and Indonesia.
Conclusion: This analysis confirmed the association of family history of breast cancer and breast cancer risk between Malays ethnicity in Malaysia and Indonesia.
A pilot study on 250 foreign workers was undertaken during a 7-month period beginning December 1996. The sample of subjects mainly males (88.8%) was selected on a non-probability basis from two sources i.e. from University of Malaya (72.8%) and PEREMBA group (27.2%). The study was a clinic-based and a face-to-face interview was carried out to elicit information on social, demographic, environmental, medical and recent illness using a structured questionnaire. Physical examinations were also performed on the same day of the interview. Subjects were also required to give their stool, venous blood, and urine specimens for microbiological, parasitological and clinical laboratory investigations. Chest X-Rays was done on ail subjects. The other investigators had already reported findings on the various specific areas of the study. In this part of the report attempt was made to relate the infectious diseases to some of the socio-environtnental variables on the 112 Indonesian, 133 Bangladeshi workers. Some aspects of health seeking behaviour of these foreign workers were also presented. Most of the Indonesian workers (84%) were from Jawa Timua and Jambi, Sumatra, while majority of the Bangladeshis (67.7%) were from two neighboring administrative districts of Dhaka and Chittagong. Majorities of the Indonesians (50.0%) were working in service industry, while 53.5% Bangladeshis were in the manufacturing. One-fifth of the workers lived in squatter areas, and nearly half of them were working for the service industry. About 70% of the workers had at least one infection. The proportion was slightly higher among the Indonesians (72.3%) compared to the Bangladeshis (67.7%). It is of interest to point out that 40.0% had multiple infections. Thirteen had five or more infections (details for the two of the 13 cases are presented as case studies). However, the findings did not indicate any association between sanitation and infections. Risk for transmission was developed based on the number of infections in the person. The Indonesian workers carried a higher risk of transmitting the diseases (33.9%) compared to 19.5% among the Bangladeshi workers. Those working in the construction industry were at a higher risk of transmitting the diseases compared to other industries. Slightly more than half of the workers experienced some form of minor illness or injury during the two-week period preceding the interview. Majority sought private care (43.1%), while 42.3% either self-medicate or did nothing al all. Nearly two-thirds paid out of their own pocket. Among the employers, construction sector made negligible contribution (2.9%) to the payment. It is interesting to find that 41.0% of the workers took some form of health suppletnents, and majority (48.4%) got it from the phartnacy or traditional sources. Nearly all (88.5%) paid on their own for the health supplements. The findings from this pilot project need to be interpreted with solne caution. However, it appears that the foreign workers carry sizeable anlount of health problems. If these are not addressed quickly it may eudanger the health of a nation, while we readily acknowledge their contribution towards our national development.
