Size and shape of Kedah-Kelantan cows

Aman A, Brown CJ, Johnson Z

Growth, 1978 Dec;42(4):486-94.
PMID: 750311

Body weight and nine body measurements were recorded on 79 mature Kedah-Kelantan cows at two locations. The Kedah-Kelantan is an indigenous cattle of Malaysia. A principal component analysis was used to study size and shape as indicated by the dependence structure among measurements. The total variation among measurements associated with the first principal component which was interpreted as a measure of general size was 40.8%. The second principal component contrasted cows tall at the withers, and deep at the chest with top line sloping downward and under line sloping upward from front to rear with those having less wither height and chest depth and straighter lines. This contrast accounted for 14.3% of the variation in body dimensions. The third principal component contrasted long, narrow, and deeper cows with a more compact type. This contrast accounted for 10.7% of the variation in body dimensions.
Fulltext A cross-cultural comparison of work engagement in the relationships between trust climate - Job performance and turnover intention: Focusing China and Pakistan

While the significance of cross-cultural research has been acknowledged over time, there remains a gap in understanding its relationship with employee outcomes. This study delves into the associations between organizational trust climate (TC) and job performance (JP), as well as turnover intention (TI), seeking to ascertain if work engagement (WE) plays a mediating role. Additionally, the research investigates potential differences in the mediating effect between China and Pakistan. Data gathered from 270 participants in China and 242 in Pakistan were subjected to structural equation modeling (SEM) for analysis. Findings indicated that perceptions of individual WE serve as a bridge between organizational TC and JP, with the effect on JP being notably stronger among the Chinese participants. Moreover, the mediating role of WE in the link between organizational TC and TI was more pronounced for the Pakistani participants. On a practical front, such insights can equip managers with a nuanced understanding of the ripple effect that a trust-infused environment can have on employee engagement, subsequently influencing performance and retention rates.

PMID: 38015132

This study aimed to measure the proportion of adverse birth outcomes among all births and maternal factors associated with low birth weight among Indigenous (Orang Asli) infants in Kelantan, Malaysia. Proportionate stratified random sampling was done to select 327 samples from five antenatal centres involved with Orang Asli in Kelantan. Multiple logistic regression analysis was used to determine maternal factors associated with low birth weight among Orang Asli infants. The proportion of low birth weight was measured at 16.2% (substantially exceeding the national rate), preterm birth at 7.3%, stillbirth at 0.6%, early neonatal death at 0.6%, and macrosomia at 0.9%,. Maternal factors associated with low birth weight infants include primiparity (AdjOR: 2.88; 95% CI: 1.44,5.78), anaemia in pregnancy (AdjOR: 2.33; 95%CI: 1.18,4.61) and hypertension (AdjOR: 4.21; 95%CI: 1.23,14.44). In conclusion, far-reaching antenatal services and nutrition policy are essential to reduce the proportions of low birth weight among Orang Asli.
Fulltext Stunting and Its Associated Factors among Children Below 5 Years Old on the East Coast of Peninsular Malaysia: Evidence from the National Health and Morbidity Survey

BACKGROUND: Child malnutrition problems still occur in Malaysia, particularly stunting. This study aimed to determine the proportion of stunting among children below 5 years old and investigate the factors associated with stunting on the East Coast of Peninsular Malaysia.
METHODS: This study utilised data from the 2016 National Health and Morbidity Survey (NHMS). Multiple logistic regression was used to determine the factors associated with malnutrition among non-stunted and stunted children.
RESULTS: The proportion of stunting among children below 5 years old in this East Coast region was 26.2%. When divided by state, Kelantan had the highest proportion of stunting, followed by Pahang and Terengganu, at 28.8%, 26.2% and 23.4%, respectively. In this study, the factors associated with stunting were children aged 24 months old-59 months old (adjusted odds ratio [aOR]: 1.52; 95% CI: 1.26, 1.83; P < 0.001), male children (aOR: 1.47; 95% CI: 1.23, 1.76; P < 0.001), Orang Asli children (aOR: 2.84; 95% CI: 1.86, 4.32; P < 0.001), children with low birth weight from 1,500 g to 2,499 g (aOR: 1.86; 95% CI: 1.36, 2.55; P < 0.001) and children from households that practice unsanitary waste disposal (aOR: 1.42; 95% CI: 1.16, 1.74; P = 0.001).
CONCLUSION: Stunting among children under the age of 5 years old on the East Coast of Peninsular Malaysia remains a public health problem. To reduce the prevalence of stunting in this region, intervention programmes should be intensified. Emphasis should be placed on public health programmes that target the associated factors, such as dietary habits, Orang Asli children, low birth weight and unsanitary waste disposal.
Fulltext MAC protocol with grouping awareness GMAC for large scale Internet-of-Things network

The development of Medium Access Control (MAC) protocols for Internet of Things should consider various aspects such as energy saving, scalability for a wide number of nodes, and grouping awareness. Although numerous protocols consider these aspects in the limited view of handling the medium access, the proposed Grouping MAC (GMAC) exploits prior knowledge of geographic node distribution in the environment and their priority levels. Such awareness enables GMAC to significantly reduce the number of collisions and prolong the network lifetime. GMAC is developed on the basis of five cycles that manage data transmission between sensors and cluster head and between cluster head and sink. These two stages of communication increase the efficiency of energy consumption for transmitting packets. In addition, GMAC contains slot decomposition and assignment based on node priority, and, therefore, is a grouping-aware protocol. Compared with standard benchmarks IEEE 802.15.4 and industrial automation standard 100.11a and user-defined grouping, GMAC protocols generate a Packet Delivery Ratio (PDR) higher than 90%, whereas the PDR of benchmark is as low as 75% in some scenarios and 30% in others. In addition, the GMAC accomplishes lower end-to-end (e2e) delay than the least e2e delay of IEEE with a difference of 3 s. Regarding energy consumption, the consumed energy is 28.1 W/h for GMAC-IEEE Energy Aware (EA) and GMAC-IEEE, which is less than that for IEEE 802.15.4 (578 W/h) in certain scenarios.
