Abstract

The Indonesian region is characterized by the activity of tropospheric convection. In the ENSO (El Niño –Southern Oscillation) event, the convective clouds displace to the eastern Pacific ocean due to the weakened trade winds. The ENSO phenomenon is the biggest player in the game of annual climate variation, while monsoon plays a role in the seasonal variations. The ENSO also brings about serious climate disaster in global area, for instance in the drought Indonesia, in the food Ecuador and so on. The influence of ENSO events is profoundley felt in some parts of the Indonesian region, i.e., the number of rainfall less than that in the pre and post ENSO years. The ENSO event also causes long dry season in the several parts of the Indonesian region, it means that rice planting will be very late. The isolines of rain factor of the value less than 5 covered a greater area in the ENSO year than that in the non ENSO years.

Abstract

In general drought in Indonesia can be predicted from intensities of El Nino that can be defined by using time series of sea surface anomaly on Pacific Ocean (SSTA 3.4). It can be shown that when El Nino with strong intensities occur then more than 65% regions in Indonesia the precipitations are below normal (drought in Indonesia). The correlation between strong El Nino intensities and percentages of regions in Indonesia with precipitations below normal are high, but when the intensities are weak the correlations are low. In this case other phenomena such as on Indian Ocean Dipole Mode (IOD) can contribute to drought in Indonesia. Clustering of climatic regions in Indonesia based on monthly rainfall pattern using fuzzy set, fuzzy relations or Kohonen’s neural network will help to clarify drought on these regions. It can be shown that climatic regions in Indonesia can be clustered based on monthly rainfall patterns that are strongly influence by Australian monsoon which is known as North Australia Indonesian Monsoon (NAIM) and Maritime Continent (MC) which has equatorial precipitation characteristic. The climatic clustering is based on the ground that ENSO and IOD are regional atmospheric dynamic so the clustering should be based on average monthly pattern or geopotential height. The east MC and NAIM will be influence strongly by ENSO and the western MC especially south Sumatra and west Java is influence also by IOD.

Abstract

Background: Estimating age from teeth is generally reliable as they are naturally preserved long after all the tissues and even bones have disintegrated. Aim of the study: The present study was an attempt to estimate the age of an individual by using modified Gustafson’s method from age related alteration in incisors and canines in Karad. Materials and methods: A cross sectional study was conducted in Karad for a period of 4 months from Nov 2018 to Feb 2019. Results: 95 teeth were observed, out of which 59 were incisors and 36 canines. The coefficient of variations among parameters ranged from 22.61 to 29.92%. Conclusion: - The estimated age error was minimized to 1.15 years. The age calculated by this method was found to be more accurate, reliable and reproducible

Abstract

Background: Identification of an individual, living or dead is of paramount importance in forensic practice,especially when dismembered body parts or skeletal remains are received for examination. Estimation ofstature is one of the important criteria in terms to determine the identity of individual. Many studies haverevealed the relationship between stature and some parts of the skeleton and the body parts in consideration.This study will helpful when only skull is available for medico-legal examination. Aim: To estimate statureof person from head length. Material and Methods: A cross sectional study was conducted in KrishnaInstitute of Medical Sciences for a period of 2 months from April to May 2018. Data was collected bymeasuring stature using stadiometer and head length using spreading calliper in 200 medical undergraduatestudents (100 males and 100 females). Results: There is low statistically significant correlation betweenhead length and stature (r=0.25 for males and r=0.22 for females). Conclusion: Accurate stature estimationis not possible from percutaneous head length
