The high cumulative capacity of toxic metals, in particular the plumbum, leads to its entry into the atmospheric air, soil and groundwater, and ultimately to accumulation in the tissues and organs of plant organisms. There is a correlation between the content of toxic metals in the atmospheric air and their fallout within the sanitary protection zone of industrial and motor transport enterprises and distribution throughout the urban ecosystem. Snow cover stores pollution, thus, it is often used to assess the state of the air. The layer-by-layer sampling of the snow cover allows determining the pollution dynamics and the influence of the production capacities of enterprises on the state of the urban ecosystem. The bioassay methods using plant organisms as test objects is based on their sensitivity to exogenous chemical effects and is reflected in the response of plants to pollutants. Determination of physico-chemical parameters of the snow cover and calculation of phytotoxic effect based on the phytotesting methods allows to detect not only the presence of toxic metals in the snow cover, but also to obtain reliable information about their distribution in the atmospheric air of cities. According to the researches results, the indexes for the lengths of Lepidium sativum shoots were obtained. The test object was germinated in a snow cover sampled at a distance of 5 to 50 m near the WOG filling station enterprise. The data obtained were compared with the values of the shoots length of test objects germinated in snow samples from the territory of the park area. It was established that the level of atmospheric air pollution with toxic metals is the highest at a distance of 50 m from WOG filling station. The physico-chemical parameters of the snow cover and the phytotoxic effect indicate a high probability of toxic metals entry into the atmospheric air beyond the limits of the sanitary protection zone of WOG filling station and into the residential areas.","PeriodicalId":131599,"journal":{"name":"Scientific Bulletin Kherson State Maritime Academy","volume":"os-50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127839713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, a method of forming a plan for loading a container ship, which provides for the placement of containers in the cargo space, which meets the requirements for landing, stability and overall longitudinal strength of the vessel. Expressions have been given to calculate the increments of static moments relative to the axes of the vessel, which arise as a result of receiving batches of containers for loading the vessel. It is noted that as a result of containers loading, the trim of the vessel should be in the range from 0 to -2,0 m. From the specified interval the trim which corresponds to placement of containers satisfying requirements of longitudinal durability has been chosen. Therefore, for loading the vessel, procedures for determining the limit values of the moments that provide the ship's trim from 0 to -2.0 m have been considered. To do this, the formulas for calculating the average weight of the batch of containers located in each of the cargo spaces designated for loading batch containers have been obtained, and expressions for determining the weight of cargo in each cargo space depending on its location along the length and height of the vessel. The procedure of joint consideration of the containers placement of different batches of loading the vessel on the parameters of landing, stability and overall longitudinal strength of the vessel has been considered. To do this, the component of the required static moment has been determined depending on the share of the weight of the party in the total weight of the vessel. To confirm the correctness of the suggested method with the help of a computer program, it was calculated to load the ship \"Sky Jameni\", which can accept containers in eight holds and on their hatches. The vessel is characterized by a maximum average draught of 13.0 m and a maximum displacement of 68,318 tons. The loading plan of the above-mentioned vessel has been formed with the help of the developed program by three container parties. The first container party includes 1900 containers weighing 28800 tons and it has been loaded in 10 cargo holds; the second one consists of 600 containers weighing 9000 tons, has been located in four holds, and the third one weighing 7200 tons and consists of 552 containers has been located in three holds. The considered loading satisfies the requirements to maintain the seaworthiness of the container carrier.","PeriodicalId":131599,"journal":{"name":"Scientific Bulletin Kherson State Maritime Academy","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122346920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the course of controlling processes, much attention is being paid to the analyses of performance indicators, high-quality and efficient management organization, clear interaction of structural divisions as well as uniformity of work performers. The paper is devoted to studying the evolution of the concept of “controlling”, features of the development of this method in relation to the operation of processes and objects of seaports in Ukraine against the background of the competitive environment escalation, deregulation of cargo traffic, and the availability of subrogation equipment. The theoretical system of controlling the work of the TTS of the seaport is made up of effectometrics. The theoretical concepts of \"process controlling\" and \"object controlling\" were further developed. The criteria for the effectiveness of the system control of a transport company are determined, which is considered to be highly necessary in order to assess the company’s expenses. Practical measures with reference to the application of the method for controlling the functioning of the TTS in a seaport, which serves the industrial and agricultural region, have been developed.","PeriodicalId":131599,"journal":{"name":"Scientific Bulletin Kherson State Maritime Academy","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130441865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The issue being discussed is not a new one and has an interdisciplinary nature. The essence and meaning of the concept of \"stress resistance\" of future maritime officers have been considered in the professional activities. Stress resistance is defined as an individual ability of a seafarer to maintain an adequate work performance at the time of stressor exposure. It has been proved that low-stress resistance leads to emotional disorders of maritime officers, reduction of physiological and mental resistance in extreme conditions of the professional situation. The number of social and personal factors influencing survival when exposed to stressors is considered here. The significance of the personal resources of future seafarers is being investigated. Personal resources may intensify or deemphasize seafarers’ respondence to stress, influencing its type, intensity, duration as well as improve their psychological resistance when in stressful situations. Personal resources include the following components: an active attitude to life, clearly differentiated goals, subjective-action intentions, ability to choose, locus of control, responsibility for their own lives, life strategies, creativity, etc. The main hypothesis of the empiric investigation has been proved. According to the latter, cadets (68%) have been mostly attaching importance to the progress of their own lives, their own self-esteem of how they got through life so far, its fruitfulness, content. The indicators of the respondents on the scales of the internal locus of control were low, which may be correlated with the low values of the indicators of the respondents, in particular on the parameter: \"completeness of the situation - lack of prospects.\" Thus, disbelief in the ability to control the events of one’s own life, elements of fatalism cause dependence on the relevant situation. According to the results of the empiric investigation, the conclusion has been drawn about the relevance of timely diagnostics to be carried out at maritime higher educational institutions, and further correction of psychological personal factors of cadets, which are important resources of stress resistance and provide the necessary level of individual mental resistance when exposed to extreme professional situations.","PeriodicalId":131599,"journal":{"name":"Scientific Bulletin Kherson State Maritime Academy","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133371623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
