Students of SMP Negeri 2 Lengayang have different interests in determining the books they are interested in, so that the library often has difficulty determining the books that are most entered by students, this is because they have not used the right system in determining the type and number of books, only based on the estimated number. Students and subjects only, as a result school students stock books of the books they want to borrow. Based on the above, a method is needed to predict and classify the amount of book stock in the future. The data used is a recap of monthly book lending, from 2018 to 2020 in the third month, with a total of 1653 transactions and 5 types of books processed, then the data is analyzed using the Backpropogation method. The results obtained are using a 5-3-1 pattern with a learning rate of 0.01, a goal of 0.01, the number of input units for the Weapon layer 5, the number of units in the hidden layer and the number of output layer units that are placed on 1 layer, and to carry out training using two phases namely feedforward and backpropagation phases. It is removed from this research that the backpropagation method can provide a classification prediction of the number of books that must be provided in the following year based on the number of data entered or the number of data entered.

The presented study discusses the phenomenon of acceptance of returning higher vertebrate species to the Czech countryside, both from the perspective of grammar school students, who can further study the environmental protection and facilitate the return of some vertebrates, and students of secondary forestry schools, expected to engage in hunting care in the future. The attitude of students and young people, in general, is very important for the acceptance of the discussed species, as not only the politicians and publicists have the right to influence the general public, but rather the specialists educated in the field should participate in the decision-making process affecting the future of these animals. Overall, the work develops a hypothesis that people may have misconceptions about the return of some vertebrates as, rather than focusing on general facts, they are influenced by frequently hyped points, such as the fear and concern of aggrieved farmers, the overpopulating of some species and the infectious diseases that some animals may transmit. A questionnaire was designed and circulated to obtain the required data. For general simplification, only three options were presented in the questionnaire, either positive, negative, or neutral attitude as further structuring could compromise the clarity of the results.

The Research aimst to compare backpropagation and Learning Vector Quantization (LVQ) methods in exploring the potential of new students at STMIK PalComTech. Comparisons in this study involve four input variables used which consist of four basic subjects of informatics engineering and information systems (math, basic programming, computer networks and management bases) which then make informatics techniques and information systems as outputs, to get the accuracy level high in this study, the researchers used several variations of parameters which eventually produced the best accuracy of the two methods. From 120 data tested using variations in test data and training data which are then processed using variations in the learning rate parameters and epochs. From the test results obtained the level of accuracy of pattern recognition in the backpropagation method is 99.17% with a learning rate variation of 0.1 and epoch 100, the learning vector quantization method has an accuracy rate of 96.67% with a variation of learning rate 1 and epoch 20 From the results of the comparison the Backpropagation method is superior in terms of accuracy so that it becomes the right method to use in exploring the potential of new students at STMIK PalComTech.

This research was conducted to study the Back Propagation ANN that was implemented with the Matlab GUI. Where the data used is the duration of shine data, the network architecture is formed by determining the number of units per layer. After the network is formed, training and testing are carried out from the data that has been grouped before. Furthermore, the prediction stage uses the trainrp training method with the logsig activation function of each layer. The number of input layer neurons is 120, the first hidden layer is 10, the second hidden layer is 10, the output layer is 1. While the maximum epoch parameter is 1000, the goal is 0.001, the learning rate is 0.7 and step is 1. Based on the simulation results January was 51.25%, February was 62.00%, March was 59.29%, April was 64.52%, May was 71.42%, June was 79.32%, July was 64.25%, August was 77.87%, September was 85.02%, October was 81.33%, November of 56.67%, and December of 39.14%. The simulation results were obtained with MSE accuracy of 5.114, MAD of 1.479, MAPE of 2.162, RMSE of 2.261, and accuracy of 97.43%.

A 55-year-old woman was referred because of diffuse pruritic erythematous lesions and an ischemic process of the third finger of her right hand. She was known to have anaemia secondary to hypermenorrhea. She presented six months before admission with a cutaneous infiltration on the left cubital cavity after a paravenous leakage of intravenous iron substitution. She then reported a progressive pruritic erythematous swelling of her left arm and lower extremities and trunk. Skin biopsy of a lesion on the right leg revealed a fibrillar, small-vessel vasculitis containing many eosinophils.Two months later she reported Raynaud symptoms in both hands, with a persistent violaceous coloration of the skin and cold sensation of her third digit of the right hand. A round 1.5 cm well-delimited swelling on the medial site of the left elbow was noted. The third digit of her right hand was cold and of violet colour. Eosinophilia (19 % of total leucocytes) was present. Doppler-duplex arterial examination of the upper extremities showed an occlusion of the cubital artery down to the palmar arcade on the right arm. Selective angiography of the right subclavian and brachial arteries showed diffuse alteration of the blood flow in the cubital artery and hand, with fine collateral circulation in the carpal region. Neither secondary causes of hypereosinophilia nor a myeloproliferative process was found. Considering the skin biopsy results and having excluded other causes of eosinophilia, we assumed the diagnosis of an eosinophilic vasculitis. Treatment with tacrolimus and high dose steroids was started, the latter tapered within 12 months and then stopped, but a dramatic flare-up of the vasculitis with Raynaud phenomenon occurred. A new immunosupressive approach with steroids and methotrexate was then introduced. This case of aggressive eosinophilic vasculitis is difficult to classify into the usual forms of vasculitis and constitutes a therapeutic challenge given the resistance to current immunosuppressive regimens.

The article discusses the future of mobility in the light of energy resources. Fossil fuel will not be available for a long time - not to mention its growing environmental and political conflicts. In analysing the potential of biofuel it is argued that the high demands of modern mobility can hardly be fulfilled in the future. Furthermore, the change into using biofuel will probably lead to increasing conflicts between the fuel market and the food market, as well as to conflicts with regional agricultural networks in the third world. Petrol imperialism might be replaced by bio imperialism. Therefore, mobility on a solar base pursues a double strategy of raising efficiency on the one hand and strongly reducing mobility itself on the other.

Choice of profession is a social phenomenon that every person has to face in life. Numerous studies convince us that not only the well-being of a person depends on the chosen work, but also his attitude to himself and life in general, therefore, the right and timely professional choice is very important. Research about factors of career self-determination of students of higher education institutions in Ukraine shows that self-determination is an important factor in the socialization of young person, and the factors that determine students' career choices become an actual problem of nowadays. The present study involved full-time and part-time students of Institute of Philology and Mass Communications of Open International University of Human Development "Ukraine" in order to examine the factors of career self-determination of students of higher education institutions (N=189). Diagnostic factors of career self-determination of students studying in the third and fourth year were carried out using the author's questionnaire. Processing of obtained data was carried out using the Excel 2010 program; factorial and comparative analysis were applied. Results of the study showed that initial stage of career self-determination falls down on the third and fourth studying year at the university, when an image of future career and career orientations begin to form. At the same time, the content of career self-determination in this period is contradictory and uncertain, therefore, the implementation of pedagogical support of this process among students is effective.

ABSTRACT Parental perception will affect the fulfillment of children’s participation rights. Fullfilment of children’s participation rights will be fulfilled optimally if parents pay anttention to opinions while providing opportunities for children to make and make decisions about the child’s goals and self-interest. The subjects studied consisted of 5 subjects consisting of father and mother who had children aged 9- 12 years. This study uses qualitative research methods, with data retrieval tools in teh form of interviews, observation and documentation. From the research found data were the subjects do not fulfill the right of participation of children up to the maximum ladder where children’s participation rights range from the first ladder to the third ladder. The first ladder to the third ladder is actually a non- participating ladder. This means that children is manipulated, dominated by parents, there is direct communation and the severity of the parent. The children felt disappointed, sad, and angry with the parents but they still tried to hear and obey the parent’s decision. Children from third and fourth subjects experienced excessive fear to speak to their parent (father). Suggestions for parents to be more caring and fulfill the rights of children’s participation so as not to affect the growth and development of children.
