Recently, many korean construction companies have faced many environmental changes and demands for external changes. This demand for external changes is necessary for all companies that is under the survival of fittest. The internal/external of environmental changes affect the organizations of company largely, and these management organizations have relation with the corporate of management performance closely. In response to that, to be adapted to the environmental change and to raise the corporate of management performance, the construction companies have tried to change the organizations such as organization re-design, organization re-build, organization innovation. Because the organizational structure that is preventive in the growth of companies bring a negative effect, the companies need to have the effective organizations to raise the corporate value. The effective organizations could be used the important indicator that builds the corporate goals and manages the organizations. Also, the organization development and organization management can prepare for environmental changes can be the important base to increase the management performance. Therefore, After surveying and analyzing the character of organization structure in respect to the OLC, this study present the Organization Structure Model that can design the appropriate organization by the growth of companies.

This study is on the abstract expressionist techniques among the art activities variously expressed in modern fashion. Its significance lies in making fashion artistic through the combination of fashion and art in contributing to the development of creative fashion culture. In terms of method, documents are used to characterize the concept of abstract expressionism, the works of representative artists, and the panting techniques in relation to modem art based on existing literature. Fashion-related anthology, domestic, and foreign fashion magazines were used to analyze the abstract expressionism applied to modern fashion since 2000. According to the findings, the abstract expressionism applied to modern fashion showed artistic expressions with the abstract beauty by chance, using only the images or techniques similar to those in abstract expressionism. Expressionist works had abstract and dynamic images, as they were given a third dimension through the process of being worn on the human body. Second, details or decorative factors were excluded to ensure the maximum space for expression, modem images were displayed using the simple forms such as silhouettes (spacious or dense) and the beauty of harmony was shown that had beauty emphasized by the expression effects of textile design, the division of space, and the composition of colors. Third, the action painting techniques in modern fashion were used for textile designs printed on the surface of clothes, and the dynamic character of the design was shown by the duplication and juxtaposition of stains created by chance. The color field abstract techniques were shown through printing, texture, and dying, in addition the intense and pure abstract images were displayed by treating clothes like large screens.

Smartphone has become a part of many people's daily lives. The mobile messenger function on the smartphone in particular is the most frequently used services. The mobile communication tool in the age of digital media can be classified into two big categories: text messages and emoticons, the non-verbal expression tool of one's emotions. This thesis has studied the mobile communications made by the non-verbal tool of emoticons. The history of emoticons traces back to the text-based emoticon created by Scott Fahlman, from which graphical emoticons were developed and the sound and animation effects have been added. Many people use emoticons and diverse companies are developing the tool. In this study, the representative emoticon development case of Line Co., Ltd. is analyzed to see the concept, types, development process, collaborations and merchandising of the emoticons. Based on the case of Line, the development orientation and direction of domestic emoticons will be discussed to be culture contents.

The relevance of the study implies the need to explain the main determinants of environmental policy, allowing countries to converge on a common working basis. The purpose of the research is to explore ways in which the environmental aspects of EU regions and territories can be shaped to apply to domestic environmental policy. A total of 997 representatives from the Ukrainian UTCs, who are involved in local environmental policy, participated in the survey. Results of the research. A hierarchy of regional environmental policy objectives has been identified. Three key principles of eco-policy development have been distinguished. The means of the innovative approach strategy implementation have been outlined (formation of the regional market of environmental services; organization of interaction between environmental agencies and market structures; establishment of environmental funds which finance environmental activities; implementation of the "collateral return" system; formation of a system of benefits and loans to enterprises that successfully implement the environmental policy). The means of the prognostic approach implementation strategy to the development of the region's environmental policy have been determined (the use of an orderly and successful long-term strategy of economic development of the region; obligatory consideration in the mechanisms strategy aimed at improvement of environmental management system of the region, interbranch impact of the projects implemented on the region's ecological situation; taking into consideration the economic and geographical peculiarities of the region, the necessary infrastructure, issues of the territorial location of the large enterprises in the region and their impact on the environment). The means of the traditional approach strategy implementation have been outlined (activity programs focused on solution of specific problems, rather than on the implementation of measures for environmental restoration and enhancement; nature conservation problems have interbranch, interdepartmental character due to unity of the region's ecosystem; tracking complexity of changing conditions (water basins, woodlands, air-mass transport), regional boundaries generally do not coincide with natural ecosystems boundaries). The practical significance of the study lies in providing recommendations for the implementation of certain aspects of Ukrainian UTC's environmental policy.

This study examined the primary features of cultural program operation instances on the metaverse platform. In addition, an interview was performed with librarians in charge of the public library culture program to get their perspectives on the viability of using the metaverse platform for each sort of cultural program. Ultimately, we intended to provide guidelines for organizing and administering a cultural program on the metaverse platform in a public library. The results showed that there are seven types of cultural programs using the Metaverse platform: library tours, education, reading, exhibits, performances, games, and events. librarians in charge of the public library culture program responded positively to the future use of library tours, exhibitions, games, and events. Education can be used depending on the character of the educational program while reading and performances are less likely to be used in the future. Regarding how to use the Metaverse platform, Zepeto was most likely to be used for tours, and Gather and Zep for education, exhibits, games, and events.

This study aims to develop a core competency model for adult college students. For this purpose, the core competencies of adult college students were derived by analyzing domestic and foreign literature studies. And the Delphi survey was conducted for the validity of core competencies. The SPSS 18.0 program was used for analysis. As results of the analysis, there are 11 core competencies of adult college students derived: communication, problem-solving and meta, interpersonal, personal management and development, digital information literacy, major knowledge, citizenship, convergence, character, professional job, and global. The core competency model of adult college students was developed by assigning numbers from 01 to 11 based on the results of the Delphi survey. Core competencies of adult college students were organically linked, so the cultivation of one core competency affects other core competencies.

There has been a lot of controversy over the claim that ancient characters were engraved on a stone plane collected near the Samsin Mountain in Hadong-gun, and that it was used as an altar based on the contents on the stone. The importance of the role of geoscience in prehistoric petroglyph research was presented through analysis and comparison with representative domestic petroglyphs. First, by examining the geological formation process of the collected stone objects, it proved that prehistoric actions were not applied. Second, as a result of comparative analysis from the viewpoints of human geography and topography with representative petroglyphs in Korea, it is unreasonable to argue that the stone was made for an altar. Third, it is considered that among the ancient characters under debate, the straight line indicates a cleavage of carbonate minerals, and the curved shape results from the growth of lichens. Finally, we propose that reproducing the lines found on the stone was impossible by using ancient techniques, and that there was no trace of any artificial actions applied to the spots considered to be curved characters. As shown in such research cases, the results of petroglyph research will have high reliability, if research by experts in each field continues after the geoscientific basis is secured. In this respect, the contribution of Earth science to cultural assets and archeology is expected to increase in the future.

In the fintech environment, ensuring secure financial transactions with smartphones requires authenticating the device owner. Smartphone authentication techniques encompass a variety of approaches, such as passwords, biometrics, SMS authentication, and more. Among these, password-based authentication is commonly used and highly convenient for user authentication. Although it is a simple authentication mechanism, it is susceptible to eavesdropping and keylogging attacks, alongside other threats. Security keypads have been proposed to address vulnerabilities in password input on smartphones. One such innovation is a group keypad, resistant to attacks that guess characters based on touch location. However, improvements are needed for user convenience. In this study, we aim to propose a method that enhances convenience while being resistant to eavesdropping and recording attacks on the existing group keypad. The proposed method uses new signs to allow users to verify instead of the last character confirmation easily and employs dragging-to-touch for blocking recording attacks. We suggest diverse positioning methods tailored for domestic users, improving efficiency and security in password input compared to existing methods.
