A Novel Tri-Stage Recognition Scheme for Handwritten Malayalam Character Recognition
AbstractThe paper proposes an efficient and novel approach of Malayalam character recognition which acquires higher recognition rate for entire character set of Malayalam script. The proposed scheme follows a three stage feature extraction. In the first stage we are grouping characters into different classes based on the number of corners, bifurcations, loops and endings. In the second phase we are identifying exact character in the class based on the different feature extraction technique specially defined for each class. In the third stage we are checking the probability of occurrence of the current character in the given position based on defined rules for the formation of words
Psychological well-being on thyroid hormone replacement
Despite 100 years after the discovery of thyroxine, controversy still exists regarding optimal thyroid hormone replacement therapy. Several anecdotal reports suggest that thyroxine alone therapy does not normalise psychological wellbeing. My cross-sectional study (n=1922) provided the first evidence in support of the hypothesis that a small proportion of patients on thyroxine alone therapy have increased psychological morbidity despite having normal TSH (publication 1). My second study was the largest randomised placebo controlled study to date to compare the effects of thyroxine alone and combined T3/T4 therapy over a 12 months period. This categorically proved that thyroxine alone therapy should be the first choice for hypothyroid patients (publication 2). Further genetic analysis of the deiodinase genes showed that a sub-group of hypothyroid patients with an SNP on D2 gene do have reduced psychological wellbeing on thyroxine alone therapy and improve on combined T3/T4 therapy compared to those without (publication 5). Both these findings were shown only by our study and were possible because of the large size (n=700). Detailed analysis of the various thyroid hormones and their ratio from our study showed that in addition to TSH, free T4 should be taken into account when treating hypothyroid patients (publication 4). My pharmacokinetic study provided the crucial and first evidence of the profiles of thyroid hormones on once a day combined T3/T4 therapy, highlighting the need to use either slow-release T3 or multiple doses of T3 in a day (publication 3). Our invited commentary and review (publications 6-8 & 10) have highlighted the importance of “individualised set points” for thyroid hormones, the complexity of thyroid hormone transport and actions as well as an algorithm for approaching hypothyroid patients. My other work (publication 9) was the first to test the possibility and provided the first evidence of deiodinase gene polymorphisms affecting circulating thyroid hormone levels and their possible role in psychological wellbeing in normal population. Thus, my work in the area, “Psychological wellbeing in patients of thyroid hormone replacement therapy” has provided several landmark findings, resulting in 10 publications including 4 in JCEM, 2 in Lancet and 1 in Clinical Endocrinology
A need for new accident theories in Malaysia?
Workplace accident is a big challenges for a safety professional. Workplace accidents may lead from minor to serious
effects to both employees and employers alike. Accident is an unexpected and undesirable event, especially those
resulting in damage, harm or unforeseen incidents. This paper also discussed all available accident theories that are
commonly used in workplace as fundamental to mitigating accident. Throughout this paper, the author justified that a
new or updated accident theory is needed in Malaysia. The author stated that current accident theories are based on
different environments and are different in terms physical of the employee who involved in the accident. This author
also stated that technology changes is also another factor which can be supporting the new or updated accident
theory needed in Malaysia
