The article provides a technical and economic comparison of costs when covering 10 classrooms of a general educational institution with LED and fluorescent lamps for a period of 10 years. The main advantage of led light sources is the high level of light output compared to traditional light sources. Replacing incandescent lamps and gas-discharge ICS with led ICS can significantly reduce energy costs. Currently, led ICS are increasingly replacing traditional ICS due to their high energy efficiency and safety. For comparison, luminescent lamps LVO04-4x14-031 and LED lamps DVO12-45-003 produced by JSC “Ardatovsky lighting plant” with a comparable light flux and light distribution were selected. The number of lamps in the 65 m2 auditorium was chosen based on the normalized illumination of 500 Lux on a horizontal work surface (0.8 m). The calculation of the number of lamps that meet all the requirements for lighting in General and higher educational institutions was carried out in the DiaLux 4.13 program. According to preliminary calculations, lighting with led lamps will reduce energy costs over 10 years by 2.16 times compared to fluorescent lamps. The maximum expenses are spent on the purchase of new led lamps. This is mainly due to the higher price of led lighting devices compared to fluorescent ones.

Aiming at the high energy-consuming characteristics of Chinese marine fishery, the application of LED in Chinese marine fishery is analyzed. It has remarkable energy-saving effect if the fishing style of trawling is replaced by light-seine fishing, and the gathering-fish lamps of metal halide lamps or incandescent lamps are replaced by LED light sources. The conversion of the trawlers to light-seine vessel and widespread use of LED light sources will lead to cut down energy consumption and increase the economic benefits. Based on rough calculation, it can make Chinese fisherfolk increase income about hundreds of millions of dollars and reduce more than millions of tons CO2 emission if the conversion of the trawlers to light-seine vessel and the replacement of metal halide lamps or incandescent lamps to LED light sources can reach 20% of all. Moreover, LED light source can use for general lighting purpose in marine fishery. All of these will cause the development of the correlative industries. For instance, the market demand of LED is very vast.

This experiment was conducted to investigate the effects of artificial light sources for light period extension on growth and flowering of statice `Sophia' and `Early Blue'. The seeds were sown on 10 June in a plug tray with 128 plugs. The seedlings were grown at the highland (800 m above sea level) for 50 days, and transplanted on 30 July in 20-cm-diameter plastic pots. High-pressure sodium lamps (HPS) (220V, 400W), incandescent lamps (Il) (220V, 200W), and fluorescent lamps (Fl) (220V, 40W) for day length extension (16-h photoperiod) as compared with short day (8-h photoperiod) were tested. HPS gave the greatest photosynthetically active radiation (PAR), but Fl did the smallest. HPS or Fl as compared with Il showed high ratio of red/far-red light. The leaves of plant grown under HPS were effective for light absorbance and chlorophyll contents. HPS promoted photosynthesis as much as light period extension, while more respiration than photosynthesis occurred under Fl affected by low PAR. Long day condition as light period extension hastened flowering of statice, and HPS or Il were more effective than Fl on flowering among artificial light sources tested. The light compensation and saturation points of statice were 50 and 500 μmol·m–2·s–1, respectively. Photosynthesis hastened at high temperature, but amount of photosynthesis at vegetative stage showed much higher than flowering stage under the condition below 20 °C These results indicated that day length extension with HPS increased productivity and quality for cut flower of statice at the highland in Korea.

Materials and methods: We have conducted surveys among 1015 students of educational institutions, residing in a large industrial center through special questionnaire was developed by SI «ICAHC NAMS». According to answer to the question about their attitude towards school, schoolchildren have been divided into 6 groups. Results: Studying the health-shaping behavior of children has shown the greatest regularity of engagement in sports activities among students of the 1st group. Schoolchildren of the 4th group were characterized by the risk of development of obesity, due to the highest (among the other groups) level of consumption of chips, crackers, street food, sparkling water, against insufficient acquirement of key sources of protein and vitamins. The same groups also differed in self-esteem of their own health and perception of school environment. Conclusions: The most safe group as to development of obesity and other diseases has been the 1st group, students of which attended an educational institution with pleasure and had a high level of physical activity and had certain eating habits. Children of the 4th group with indifferent attitude towards any occupation should be included into the risk group. Outstanding remains the issue in-depth study of prevalence of healthy lifestyle skills and bad habits among various gender groups of adolescents.

The article notes that in recent years Ukraine has identified new priorities for the development of its education system. Since 2018, the concept of the New Ukrainian School has been introduced in general secondary education institutions. There has been created an appropriate legal framework, and practical reforms in the field of education have begun, i.e. the Ukrainian school must change radically. One of the priorities of the state's development is inclusive education, which is one of the main factors in reforming the system of institutional care and upbringing of children in Ukraine. This means that in general educational institutions in classrooms different children will learn and interact together, including children with special educational needs. The goal of educational institutions is the all-round development of any child, creating conditions for the assimilation of effective models of behavior with peers, taking into account all the features of the development of each individual child. However, frequent occurrences of violence, bullying and a high level of conflict among peers do not allow schoolchildren to fully achieve their goals. The article considers the problems that students may face during the educational process in inclusive learing institutions; one of the issues is bullying in the children's community. The authors analyzed the legislation of Ukraine on combating bullying. They outlined the measures of preventive work of teachers to prevent bullying. As a result, the prevention of bullying in educational institutions contributes to the improvement of the microclimate in communities and the creation of a safe educational environment in educational institutions. The establishment of school services of mutual understanding and implementation of a restorative approach can improve the socio-psychological microclimate in school (or higher educational institution) communities, creating a safe environment for all participants of the educational process, because it is a well-established process of interaction between mediators, an efficient way of peacebuilding and nonviolent communication.

"Gro-lux" fluorescent lamps, a light source providing high energy in the blue and red regions of the spectrum, were designed and marketed by the Sylvania Company (4) especially for growing plants under artificial light. Their effectiveness for growing tomato plants was compared with that of cool-white fluorescent lamps, with and without adding 35% of the fluorescent wattage as incandescent light. On a percentage basis the dry weights of the stems and leaves after 5 weeks were, cool-white 100%, gro-lux 82, cool-white plus incandescent 131, and gro-lux plus incandescent 153. The addition of incandescent to gro-lux fluorescent as compared with gro-lux alone resulted in 44% increase in root dry weight, 73% increase in leaf area, and 80% increase in plant height. The increased growth obtained under either gro-lux or cool-white when incandescent is added is attributed to an increase in plant height caused by the addition of far-red energy, permitting more light to reach the lower leaves. Plants grown under gro-lux with incandescent had 34% more flowers, 20% more ripe fruit, and 32% heavier fruit than those grown under cool-white with incandescent.
