In tropical countries,scorpion sting is a significant cause of disease,leading to severe localized cutaneous reactions,neurologic impairments,and respiratory distress,as well as myocarditis[1].The world’s most poisonous scorpion species,Leiurus quinquestriatus,is found in southern Turkey and is a threat to the public’s health in all of the provinces,particularly in Adiyaman and its surrounding areas,which were hit by the recent Turkey and Syria earthquake[1].

Radiant cooling system for thermal comfort of Thai people was developed. Questionnaires for subjective experiments were examined for development of radiant cooling system for thermal comfort. Thermal sensation, humid sensation and air movement sensation were used for thermal comfort assessment. The Predicted Mean Vote (PMV) value was used for thermal comfort evaluation and it was observed that the PMV values are in the comfortable ranges during 18:00 to 10:00 for air velocity 0.2 m/s and 0.4 m/s. Comfortable periods are extended for higher air velocity. Neutral temperatures are in the ranges of 26.44℃-33.60℃. The percentage number of dissatisfied (PPD) value for each air velocity was also investigate and the value of PPD is five for zero value of PMV. Simulation and experimental results were evaluated by using three indicators, namely, the coefficient of variation (CV), the mean bias error (MBE) and Chi-Square (x2). The values of CV, MBE and (x2) for mean radiant temperature are 14.52%, 1.54% and 3.95℃, respectively. Zones of acceptable thermal environment were developed for Thai People. Results revealed that the comfortable zones of Thai people are in the ranges of relative humidity 50% 70% and effective temperatures (ET) 24℃ 27℃.

Retrorectal(also known as presacral) tumor(RT) is a rare disease of retrorectal space. They can be classified as congenital, inflammatory, neurogenic, osseous, or miscellaneous. The most common presentation is an asymptomatic mass discovered on routine rectal examination, but certain nonspecific symptoms can be elicited by careful history and physical examination. The primary and only satisfactory treatment is surgery for RTs. Three approaches commonly used for resection are abdominal, transsacral, or a combined abdominosacral approach. Prognosis is directly related primary local control, which is often difficult to achieve for malignantlesions.
