The objective of the present study was to identify the microbiota present in the hands of academics and teachers of a Higher Education Institution in the municipality of Primavera do Leste - MT. Samples were collected from 24 volunteers using a swab. Of the samples collected, 19 (79.1%) showed bacterial growth in a nutrient culture medium, being isolated from this: Staphylococcus aureus (31.6%), S. lugdunensis (31.6%), S. epidermidis (15.8%), S. spp. (5.8%) and Escherichia coli (5.2%). The occurrence of bacteria found in the hands of the volunteers makes it possible to infer that the hands can act as a means of transmission and microbiological multiplication. To avoid this transmission, hygiene and antisepsis measures should be adopted regularly.

The aim of this study was to evaluate, through chemical and bacteriological parameters, the water quality from drinking fountains at a Federal Higher Education Institution, in different climatic periods. Total coliforms and Escherichia coli were quantified by the enzyme method of the defined substrate; heterotrophic bacteria by plating in depth in Plate Count Agar; pH and chlorine, using commercial kits. The research was conducted in two stages: the first one, referring to the initial analyses during the rainy season, with the verification of the presence of samples in disagreement with the current legislation; and the second, during the dry period, after the corrective measures adopted in function the results obtained in the first stage, totalling 89 samples in both stages, from 49 drinking fountains. In the first stage, bacteriological evaluations showed that 65.3 % of the samples were inadequate, while in the second, the failure rate was 20.4 %. The parameters evaluated in the two stages revealed that there was no significant result (p˃0.05) in relation to pH, total coliforms and Escherichia coli. Unlike what was observed for mesophilic aerobic and chlorine content (p<0.05), which are believed to have been influenced by climatic conditions, with higher rates of non-compliance in the first stage, that is, found in the rainy season. These findings demonstrate the existence of inadequate hygienic-sanitary conditions and the need of frequent monitoring of water quality, as well as the positive impact after the educational intervention and the adoption of preventive and corrective measures, aimed at the safety of the consumer community.

Educational system is the most important social institution, which provides the development of a personality and frames his/her worldview and the conception of subjective well-being. Despite the large number of studies on the issue of psychological and pedagogical security of educational environment, the sphere of higher education still remains underexplored. The available empiric material has not received sufficient methodological justification and conceptualization. This article aims to provide the conceptualization of the risk category as applied to the educational environment of a higher education institution, as well as empiric investigation of the risks within the educational environment as viewed by applicants and students.Materials and methods. 213 applicants and 547 students of the Kuban State Technological University took part in the survey. The following investigation methods were used: expert assessment, interview, questioning, content analysis, analysis of means method, cluster analysis and factor analysis.Investigation results. Comparative examination of the manifestation degree of risks within the educational environment as viewed by applicants and students of higher education institution showed significant differences in the assessment of risk by these groups of respondents. From the point of view of applicants, the main risks are connected with social and psychological aspects of the educational environment of a higher education institution, relations within student groups and interaction with teachers, as well as with the issues related to the educational management and leisure arrangement. As viewed by the students, the risks within the educational environment include external and social and psychological risk factors, motivating risks and risks arising from the learning process organization and management and the related issues. Applicants’ notion of the risks within the educational environment of a higher education institution was mainly influenced by information they received from media and by the opinion of their relatives and age mates.Consideration and conclusions. It was proved that the applicants’ idea of the risks within the educational environment of a higher education institution is determined by the opinion of people they know personally, however it changes during the process of studying in higher education institution and acquiring their own experience of being within the environment. The investigation results allow creating a model of psychological and pedagogical security within the educational environment of a higher education institution. This model makes it possible to forecast main risks of the educational environment, their development, and evolvement and find solution to them.

<p><em>Metil merah merupakan salah satu zat warna golongan azo yang sering digunakan dalam industri dan laboratorium. Penggunaan metil merah dapat menimbulkan efek terhadap kesehatan dan lingkungan. Oleh sebab itu dilakukan metode fotodegradasi dengan menggunakan semikonduktor dan radiasi sinar tampak. Semikonduktor yang digunakan yaitu berbahan dasar tembaga sulfat hidrat dan perak nitrat. Prekusor tembaga sulfat hidrat dibuat dari pengolahan limbah logam tembaga hasil pemotongan tembaga yang ada di bengkel Lembaga Ilmu Pengetahuan Indonesia (LIPI) Bandung. Bahan semikonduktor juga memiliki kemampuan dalam menghambat pertumbuhan bakteri. Hasil optimum yang didapatkan dalam proses fotodegradasi dan antibakteri merupakan gabungan antara kedua prekusor tembaga sulfat hidrat dan perak nitrat dengan bantuan penyinaran. Kemampuan dalam menghambat pertumbuhan bakteri didapatkan persentase kematian 100 % untuk masing-masing bakteri, yaitu Escherichia coli dan Staphylococcus aureus. Aktifitas fotokatalitiknya dengan konsentrasi semikonduktor 10 ppm untuk mendegradasi zat warna metil merah 5 ppm, selama 23 jam, dimana persentase degradasi yang didapatkan dengan penyinaran lebih tinggi dibandingkan dengan tanpa penyinaran. Pengaruh pH larutan terhadap degradasi metil merah yaitu optimum pada pH 12 (basa).</em></p><p><em><br /></em></p><p><em>Methyl red is one of the azo group dyes that is often used in industry and laboratories. The use of methyl red can have an effect on health and the environment. Therefore photodegradation method is done by using semiconductor and visible light radiation. The semiconductor used is based on copper sulfate hydrate and silver nitrate. The copper sulphate hydrate precursor is made from the processing of copper-cut copper metal waste in the workshop of the Indonesian Institute of Sciences (LIPI) in Bandung. Semiconductor materials also have the ability to inhibit bacterial growth. The optimum results obtained in the photodegradation and antibacterial process are a combination of both copper sulfate hydrate precursor and silver nitrate with the help of irradiation. The ability to inhibit bacterial growth obtained 100% mortality for each bacterium, namely Escherichia coli and Staphylococcus aureus. Photocatalytic activity with 10 ppm semiconductor concentration to degrade methyl red dye 5 ppm, for 23 hours, where the percentage of degradation obtained by irradiation is higher than without irradiation. The effect of pH of the solution on the degradation of methyl red is optimum at pH 12 (base).</em></p>
