Electronic educational environments in the conditions of quarantine restrictions of COVID-19 have become a common phenomenon for the organization of distance educational activities. Under the conditions of Russian aggression, Ukrainian proof of their use is unique. The purpose of the article is to analyze the role of electronic educational environments in the process of training applicants for higher education in Ukraine in the realities of a large-scale war. General scientific methods (analysis, synthesis, deduction, and induction) and special pedagogical prognostic methods, modeling, and SWOT analysis methods were used. In the results, the general properties of the Internet educational platforms common in Ukraine, the peculiarities of using the Moodle and Prometheus platforms, and an approximate model of the electronic learning environment were discussed. The reasons for the popularity of Moodle among Ukrainian universities are analyzed, but vulnerable elements related to security are emphasized. It was also determined that the high cost of Prometheus software and less functionality made this learning environment less relevant. The conclusions state that the military actions drew the attention of universities in Ukraine to the formation of their own educational platforms. This is especially relevant for technical and military institutions of higher education.

The purpose of this study is to analyse the realities of fundraising and distribution of the local community chest in Korea. Until now little empirical study has been conducted concerning the culture of giving. Using the sample of 900 citizens selected from 7 cities and another sample of 230 from policy-making group in 16 local community chest, this study analysed empirical1y how the capacity, motivation and opportunity of the prospective donors are related to giving and the current issues of fundraising and distribution. According to the results of analysis, the level of motivation in giving culture is very low. Also it was found that religious beliefs is the most important motivating factor in giving. Participation in volunteer activities is another important factor to influencing giving. Some effective fundraising strategies are suggested including strengthening the motivation of prospective donors, workplace donation and joint-fundraising with religious organization or other foundation, coordinating fundraising activities between the community chest and other social welfare agencies. Program-oriented distribution and change of some distribution standards are stressed as an effective distribution strategy.

The objectives of this study are to consider about the research of a costume and a discussion about a system of costume by practical science scholar in the late period of Chosun Dynasty. The result are descrived as follows: 1. The purpose that practical sciellce scholars researched a costulne was not only the intellectual research but also to make a basis in order to reform a uncorrected costume's system. Their study had two point. The one was the investigating research about the origin and change of the costume. The other was the study about a formation of costume. 2. The practical science scholars determined the directions to reform a wrong costumes' system on the basis of the research about a costume. They had three directions. Those were a conservatism, a rationalism to think the realities of life and a reformation. 3. The practical science scholars' thinking was to pursue the origin form and the practical use. This two axis show the direction to improve our costulne's culture now a day.

Agricultural extension services in Korea has experienced various system changes and accomplishments. The biggest achievement of extension was rice self-suffiency in the 1970s and abundant vegetable and animal production in the 1980s. The emerging challenges of international competition and localization are contributing to significant changes such as the decentralization of activities and shared responsibilities between the central government and local governments. Change, while it threatens the status quo, is a challenge and an opportunity to review and revamp ensconced and often rigid structures. In this sense, it is time to start a new era in agricultural extension. The development of agricultural extension requires keen appraisals and cogent analysis based on the realities of each specific regional situation. In order to develop agricultural extension services, the various aspects, the synthetic identification of its environments, the clarification of the client, the program development, and the effective mechanisms between research and extension must be considered. Especially, agricultural extension systems should be flexible and adjust to changing environments and the farmers' needs.

This study aims to obtain new design factors in terms of constructing rural apartment houses fit for the actual farm life. To carry out this study, field studies and personal interviews have been made on the living mode and using realities in the unit spaces of the rural apartment houses. The houses surveyed are the rural apartments in Chungbuk Province which were built by the public program to improve old farm houses. The results are as follows. The living modes .in the unit spaces of the rural apartments are very similar to those of the urban apartment houses. But compared with the urban indoor-living modes, the rural life is keeping more of the traditional sitting way-of-living. Accordingly, it is quite necessary to consider the nature of farm life and the sitting way-of-living in designing the rural apartment houses.

Since of 2000s, Office furniture have been much changes in the design as the expanding demand for the diversity and variability of office space. Especially, OA System Furniture including Panel System were developed by the shape and configuration considering the members' communication and teamwork. However, It is limited to the situation for the leading manufacturer of office furniture, Most small business cope with a negative policy because development personnel and expense. Thus, Accounted for the majority of the office furniture manufacturing, Small and medium-sized furniture manufacturers are needed measures of development that reflect these realities, rapid and practical. This study suggests redesign in a way that a small and medium-sized furniture manufacturers to overcome the limited design development environment and rapidly respond to changing market conditions. And this study has an intend to develop the Office Panel System.

The classical Geometric Brownian motion (GBM) model for the price of a risky asset, from which the huge financial derivatives industry has developed, stipulates that the log returns are iid Gaussian. however, typical log returns data show a distribution with much higher peaks and heavier tails than the Gaussian as well as evidence of strong and persistent dependence. In this paper we describe a simple replacement for GBM, a fractal activity time Geometric Brownian motion (FATGBM) model based on fractal activity time which readily explains these observed features in the data. Consequences of the model are explained, and examples are given to illustrate how the self-similar scaling properties of the activity time check out in practice.

SLA(Scanned Linear Array) is a portable display unit for implementing next-generation virtual realities, utilizes a design that light generated by a line of LEDs is reflected from the rapidly oscillating mirror to generate a raster display. Reaction forces generated by the motions of the mirror and counter-balance mass cancel each other at the device base, reducing vibration. Metal leaf springs have been extensively applied in such portable units. Magnetic springs have been developed and adopted that can replace the metal spring and can avoid many disadvantages of metal springs. We model and analyze the dynamics of the structure with magnetic springs and present the simulation and experimental analysis results, which can be utilized for identifying and eliminating possible problem sources in removing shaking forces and moments, and oscillating the mirror at the required amplitude and frequency. Finally, we present the improved novel magnetic actuator model which can be applied in portable display units.

After 1960s, a radical change was taken place in the modern urban theories which were developped by many architects and planners like Ebenezer Howard, Tony Garnier, Le Corbusier, Ludwig Hiberseimer, and Patrick Abercrombie. Many contemporary architects like Kevin Lynch, Aldo Rossi, Christopher Alexander, Colin Rowe, Rem Koolhaas, and Bernard Tschumi have a view that modern urban theories lost their abilities to organize and control new realities so that new urban theories was needed in order to cope with urban problems in the 1960s. In this study, we are to examine contemporary urban theories in comparison with modern urban theories and to clarify the role of discourse of language in its emergence. In consequence we can detect four main themes in the process of transformation from modern urban theories to contemporary urban theories : from functionalism to formalism, from historicism to archeology, from space to placeness, and from hierarchical organization to network. And we can prove that such themes basically depend on the discourse of language.
