The article analyzes the features of the formation of a person's value attitude to the worldview by means of information technologies. The present considers it necessary to form a person's value attitude to the perception of the world by means of information technologies. The explosive development of information and telecommunications technologies has become a determining factor in the development of modern society, which is called the information or Global Information Society. It is not yet fully formed, and we are all participants in the development of the Global Information Society. The article considers the basics of a harmonious worldview of a person, which is the basis for the formation of outlook ideas, views, knowledge, beliefs about the surrounding world, which determine the place and role and motivate actions in relation to the surrounding reality through the prism of value orientations. Worldview is considered as an integrity of relatively stable schemes, behaviors, feelings, thinking, vision of the surrounding world, inherent in an individual child, ethno-cultural and socio-cultural groups. The concept of "worldview" as a component of the multi-level structure of the individual's outlook is defined. The features that characterize a person's perception of the world are revealed. The main educational value of information technologies in the formation of a person's value attitude to the perception of the world is highlighted, which consists in the fact that they allow you to create an immeasurable brighter multi-sensory interactive learning environment with almost unlimited potential opportunities that fall at the disposal of both the teacher and the student. The trend of forming a person's value attitude to the perception of the world is clearly developing in the direction of mixed learning as a process that creates a comfortable information educational environment, communication systems that provide all the necessary educational information. The approach to student development by means of the educational environment and the formation, while in the person of a value attitude to the perception of the world by means of Information Technologies, has many pedagogical advantages, which is considered in the article.

Objective: This study was to determine the relationship between estimated breeding value and phenotype information after farrowing when juvenile selection was made in candidate pigs without phenotype information. Methods: After collecting phenotypic and genomic information for the total number of piglets born by Landrace pigs, selection accuracy between genomic breeding value estimates using genomic information and breeding value estimates of best linear unbiased prediction (BLUP) using conventional pedigree information were compared. Results: Genetic standard deviation (${\sigma}_a$) for the total number of piglets born was 0.91. Since the total number of piglets born for candidate pigs was unknown, the accuracy of the breeding value estimated from pedigree information was 0.080. When genomic information was used, the accuracy of the breeding value was 0.216. Assuming that the replacement rate of sows per year is 100% and generation interval is 1 year, genetic gain per year is 0.346 head when genomic information is used. It is 0.128 when BLUP is used. Conclusion: Genetic gain estimated from single step best linear unbiased prediction (ssBLUP) method is by 2.7 times higher than that the one estimated from BLUP method, i.e., 270% more improvement in efficiency.

Interference occurs by signals received from directions that were different from the signals of the users in a mobile communication system. Various studies have been undertaken, including diversity, equalizer, etc., in order to reduce interference. In this study, the weighted value of the array antenna was obtained to improve signal-to-noise ratio. The weighted value was obtained as an eigen value and an eigen vector by using the correlation coefficient of the signal. The weighted value obtained was then applied to the CDMA system to increase system performance and capacity. Both QPSK and OQPSK modulation systems were applied to analyze performance.

The purpose of this study is to investigate those factors that are influenced when a user recognizes his/her private information value as an economic asset. The relationship among these factors will also be discussed. This research targets Internet users, and the value of their private information will be converted into economic figures. How economic value changes in relation with individual attributes, dealer's traits, and circumstantial properties will also be studied. The changes in the factors of private information value under different situations will be analyzed from an economic perspective. By using the cost-benefit analysis framework, this work hypothesizes that the user's private information value can be influenced by individual attributes and situational properties. in the business aspect, this study can help users recognize the true value of their personal information and minimize the cost resulting from private information security incidents. This work also highlights the necessity of estimating the scale of investments for protecting private information. Overall, this research will proceed under the hypothesis that the users' recognition of their private information value is influenced by the attributes of the individual, dealers, or situations.

It is needed to evaluate information systems actively which has already developed to improve future performance of the organization and foster the activation of information system. The introduction or development of information system also can bring about a organizational success. To measure exactly the organizational performance of information systems, it is needed to develop a new valuation model for a specific information system from a objective pint of view, as well as to equip a standard methodology using BSC measurement. The information system valuation from a objective point of view is of importance as the basic information for the decision to obtain information system. This paper takes aim at investigating a new information system valuation model and developing a information system valuation system using case-based reasoning for predicting currency value of information system in each organization. A new information system valuation system is developed as a web-enabling base. Using this, users are able to estimate the value of specific information system on a real time efficiently.

Purpose - This study examined the relationship between the priorities of information, usability, mobility, reliability and empathy, which are the lower dimensions of mobile tourism app service characteristics, on the perceived value and satisfaction of tourists. Research design, data, methodology - Data collection was conducted from June 10, 2019 to June 20, 2019, and a total of 500 questionnaires were distributed to collect 352 copies. Factor analysis, reliability verification, and covariance structure analysis were carried out using SPSS 23.0 and AMOS 23.0 for 321 parts for statistical analysis. Results - First, information, mobility, reliability, and empathy have a significant effect on perceived value. However, usefulness did not appear to have a significant effect on perceived value. This analysis results can increase the reliability of the tourism app, it can be seen that the accurate tourist information services are used in the tourist app or in the place required. Second, information, usability, mobility, and empathy had a significant effect on satisfaction. However, reliability did not have a significant effect on satisfaction. Third, perceived value had a significant effect on satisfaction. Fourth, it had a significant effect on information, empathy, and intention to use. However, the usefulness, mobility, and reliability did not have a significant effect on the behavioral intention. Lastly, perceived value and satisfaction had a significant effect on behavioral intention. Conclusions - The analysis result is that the tourism app that is being used is provided with a reliable and accurate tourism information service, it can be seen that you are using the tourism app in the place or on the go. Therefore, it is relatively difficult to use the tourism app, and it is easy to understand the contents of the service and timely information. Therefore, it is possible to communicate with other users and provide customized services according to needs and desires. The study has the following limitations. This may influence the progress of the research because the respondents' responses to the mobile tourism app service are from different experiences. In addition the accuracy of providing accurate information, the usefulness of using the mobile tourism app, and the ease of communicating with other users can be understood as being relatively satisfactory.

This study attempts to suggest a model on the factors of the experiential intent. We propose a model that includes (1) the entertainment, aesthetic, empathy, information as exogenous constructs, (2) utilitarian value and hedonic value, as mediating constructs (3) experiential intent, as endogenous construct. To test the model, we analyze the data using the LISREL structural modeling. The results of our analyses suggest, as expected, that program traits -entertainment, aesthetic, empathy, information- influence utilitarian value and hedonic value, in turn, utilitarian value and hedonic value influence the experiential intent. We conclude with a discussion of managerial implications, including the potential to advance understanding the factors of experiential intent on broadcast program.
