The Temple

India has a great cultural heritage of temples across the country. There is a wide variety of temples of variety of deities constructed from East to West and North to South of India. Most of the temples are built centuries ago and still are in good condition and the centre of cultural activities. Mahalaxmi temple precinct is a very old precinct in Kolhapur, built in 8th century by Chalukyan rulers. Every year lacs of devotees are visiting this temple of goddess Mahalaxmi from most of the part of India. The temple is constructed of basalt stone with beautiful intricate carving on it. This paper focus on indoor environmental quality of the temple which is deteriorated due to the impact of increased number of devotees. Some of the devotees face the problem of suffocation, fatigue, fainting, irritation, nasal congestion; as provision of vents are absent and natural ventilation is not available inside the shrine of goddess Mahalaxmi. Due to lack of air exchange and natural ventilation the indoor environmental quality is deteriorated. It is observed that the CO2 level is increased, decreased in O2 level, rise in temperature and humidity above the standard level causing discomfort.

Inappropriate use of antibiotics may lead to antimicrobial resistance. In 2012, Dr. Soetomo Hospital conducted training for pediatric residents on the proper use of antibiotics to limit antimicrobial resistance.Objective To evaluate the impact of a rational, antibiotic-use training program for pediatric residents on their antibiotic prescriptions for patients with typhoid fever.Methods A cross-sectional, analytic study was conducted. We collected data from children with typhoid fever who were hospitalized in Dr. Soetomo Hospital, pre- and post-training on antibiotic prescriptions. Children with other known bacterial infections or who were discharged on request were excluded. Antibiotic prescriptions were evaluated using Gyssens algorithm based on the local protocol. Chi-square test was used to compare the quality of antibiotic prescriptions, before (year 2012) and after (year 2013) the training.Results Forty-nine patients with 67 prescriptions in 2012 and 34 patients with 48 prescriptions in 2013 fulfilled the inclusion criteria. Patients’ ages ranged from 1-18 years. Diagnoses of uncomplicated and complicated typhoid were found in 74% and 26% of subjects, respectively. First line (chloramphenicol, thiamphenicol, ampicillin, trimetroprim and sulfametoxazol) and second line (ceftriaxone and cefixime) use were 72% and 28%, respectively. All patients were discharged in good condition. Appropriate use of antibiotics was noted in 61% of subjects in 2012 and in 81% of subjects in 2013 (P=0.036). The most common type of error in 2012 and 2013 was dosage imprecision (25% and 17%, respectively).Conclusion Training on appropriate use of antibiotics significantly improved the quality of antibiotics prescribed in children with typhoid fever in Dr. Soetomo Hospital.

The article analyses Lithuanian rivers, 32 of which have been selected as non-complying with the require-ments of good condition. Furthermore, 15 discharge facilities that discharge wastewater to the aforementioned rivers from agglomerations with population equivalent (PE) greater than 2,000 have been selected. The assessment of the quality of treated wastewater according to the allowable impact on the reception facility has been carried out and has been compared with the currently regulated minimum allowable values of concentrations of pollutants. The analysis of the impact of quality of treated wastewater on the ecological status of rivers has been presented. It has been established that the pollution of rivers would be decreased by an average 8% (organic pollutants and total nitrogen) and by 22% (total phosphorus), if the allowable concentrations of pollutants according to the impact on the reception facility were ensured in the analysed treatment plants with PE greater than 10,000.
