As stock market gets bigger, use of HTS(Home Trading System) is getting increased in stock exchange. HTS provides lots of functions such as inquiry about stock quotations, investment counsel and so on. Thus, despite the fact that the functions fur convenience and usefulness are developed and used, security functions for privacy and trade safety are insufficient. In this paper, we analyze the security system of HTS service through the key-logging and sniffing and suggest that many private information is unintentionally exposed. We also find out a vulnerable point of the system, and show the advisable criteria of secure HTS.

Recently, implementation of telemedicine in Korea has been conducted as one of pilot projects with public health doctors. To manage and expand telemedicine services sustainably, it is necessary to understand the positions of various stakeholders. The purpose of this study is to observe and describe major phenomena around stakeholders related to telemedicine to capture major issues following the implementation of telemedicine. This study interviewed 24 research participants, including public health doctors who participated in the pilot project for telemedicine services. As a result of analyzing the interview manuscript using the grounded theory method, totally 68 concepts were derived at the coding stage, and 19 sub-categories, 11 categories, were proposed through the categorization process. In addition, through the elicitation concepts and categories of this study, conflicts among stakeholders were explained, conceptual models that presented the process of resolving conflicts, and five types of stakeholders were proposed. This study has theoretical and practical implications in that it captures and describes important issues from stakeholders in telemedicine services. The results of this study are expected to give some hints for problem solving to all of the stakeholders who wish to successfully build telemedicine services.

Animals exhibit certain behaviors and movement patterns as they react to their internal needs, external stimuli, and surrounding environments. They have a bounded range in which they mostly spend their time, and it is referred to as a home range. Based on the fact that the home range is a critical area for the survival and preservation of species, there has been a growing body of research on developing more precise home range estimation methods to use the estimated ranges as a ground for establishing an effective conservation policy since the early 1940s. Recent rapid advancements in telemetry technology that resulted in the presence of autocorrelation between locations with short time intervals revealed the limitations of the existing estimators. Many novel estimators have been developed to compensate for it by incorporating autocorrelation in calculating home ranges. However, studies on the animal home range are still in their early stage in Korea, and newly developed methodologies have not yet been adopted. Therefore, this study aims to introduce the foreign home range estimation methods and foster domestic research activities on home ranges. Firstly, we compared and contemplated seven estimators by categorizing them into geometrical and statistical methodologies and then divided them into estimators that assume independent observations and those that consider autocorrelation in each category. After that, the home ranges of black-tailed gulls (Larus crassirostris) were calculated using GPS tracking data for the month of June and derived home range estimators by applying the methodology introduced in this study. We analyzed and compared the results to discuss the strengths and weaknesses of each method. Lastly, we proposed a guideline that can help researchers choose an appropriate estimator for home range calculation based on the animal location data characteristics and analysis purpose.

1950-meter-tall goddess is Seolmundae Grandmother with the head of the 1950m Hallasan Mountain Baengnokdam and the body of the mountain ridgeline. Seolmundae Grandmother in Jeju is a folk belief that has been passed down from generation to generation in Jeju. Unlike inland, Seolmundae Grandmother, which had femininity in the customs of Jeju, which was a matrilineal society, developed into an absolute faith in Jeju, metaphorizing that in some way it was inevitable. Seolmundae Grandmother was the only subject that could mentally solve the biggest problem for Jeju residents, even if they were disconnected from the mainland. In other words, Seolmundae Grandmother was unable to make underwear for Seolmundae Grandmother because it was short of 100 bottles of silk, the god of Hallasan, a huge being and a physical symbol. Therefore, Semyungju Grandmother gave up the bridge connecting the mainland and Jeju. In this paper, focusing on the fact that Mt. Halla, covered with snow in winter, is like a skein of silk thread that we usually use in our daily lives, the etymology of Seolmundae has been changed to Saengmyeongju, - Semyungju, which is a skein of fine silk. As a basis for this, there is a custom of tying a thread of silk in 'Semyungju', a shrine to Semyeongju in Halmangdang, 'Hanmosal' along the coast of Pyoseon-myeon. The silk thread is the core of the Packing DNA gene. The summit of Mt. Halla, Ninety-Nine Valleys, and five hundred generals, found in Seolmundae Grandmother or White Silk, expressed the symbols of Jeju. The Packing DNA gene was found to originate in the Jeongnang

In this study, LD construction cases of overseas libraries were analyzed with focus on published datasets, reused vocabulary, and interlinked external datasets, and based on the analysis results, basic data on LD construction plans of domestic libraries were obtained. As a result of the analysis of 21 library cases, overseas libraries have established a faithful authority LD and conducted new services using published LDs. To this end, overseas libraries collaborated with other libraries and cultural institutions within the region, within the country, and nationally under the leadership of the library, and based on this cooperation, a specialized dataset was published. Overseas libraries used Schema.org to increase the visibility of published LDs, and used BIBFRAME for subdivision of description to define various entities and build LDs based on the defined entities. Overseas libraries have utilized various defined entities to link related information, display results, browse, and download in bulk. Overseas libraries were interested in the continuous up-to-date of interlinked external datasets, and directly utilized external data to reinforce catalog information. In this study, based on the derived implications, points to be considered when issuing LDs by domestic libraries were proposed. The research results can be used as basic data when future domestic libraries plan LD services or upgrade existing services.

The problem of freedom is inseparably related to human life. It makes this not to be regarded as a problem restricted to the professional domain of ethics. It suggests rather that the problem of freedom is intimately connected with the philosophical groundwork for discussing the future direction of society, culture and science, and its regulative idea, a philosophical discussion which comes up inevitably with various social, economic and political problems, and problems related to the spirit of law. In this view, when we want to explain the problem of freedom as a fundamental one in reference to future direction of humanities and to find out a solution to this, our research only in accordance with the approach of history of philosophy runs into difficulties. The reason is that the problem of freedom has nowness together with historicity. Finding this problem to be a present one in our concrete human life, we can discuss it more meaningful under the methodological frame changed and developed by philosophical reflections since the modern age. And here I think a culturalistic approach reinterpreting hermeneutic insight and pragmatistic context methodologically can provide a pertinent clue for a theoretical work to investigate the problem of freedom and to find a solution to that because this approach considers historicity and nowness. For this purpose analysing truth intersubjectively and understanding freedom critically, this article tries to reconstruct symbolic interpretation and the concept of self constructed in community of language and action as a cultural horizon of freedom.

The purpose of this study is to discover the occupational identity by examining the narrative of the life of a vocational training teacher with self-esteem in programming fields. The following six types of occupational identity were found: 'a positive image of a vocational training teacher(fits oneself)', 'I feel proud of myself while doing vocational training activities.', 'a teacher who continues to develop him/herself as an expert in the subject class', 'a teacher who immerses him/herself as an expert on student change and growth', 'a teacher engaged in leading activities to create opportunities for vocational training', and 'a teacher of continuous pursuit'. This study has significance in exploring the structure of occupational identity recognition and experience of its formation of a self-esteemed vocational training teacher in programming fields, which have not been studied.

What are the implications for us through the discussion on the effect of Germany's dual system of vocational education on the youth unemployment rate? You can find out what kind of evaluation Germany is receiving on the dual system vocational education system implemented based on the 'Vocational Education and Training Act' (Berufsbildungsgesetz), and the specific system establishment form for the industry-academic-government cooperation system. It was possible to present the crises and problems of these systems. Responsibility for the dual system of vocational education in Germany rests with the national and state ministries of education, and private enterprises and chambers of commerce are responsible for business practices. Practical work in a company is conducted through skill-oriented education, and in vocational schools, competency-oriented theoretical education is received. In addition, the necessity and demand for digital vocational and education training in accordance with German Idustrie 4.0 and higher vocational education degree acquisition through dual-degree courses were identified. It can be seen that the youth unemployment rate is the lowest in Europe due to the successful development and utilization of human resources to improve the competitiveness of companies, such as dual vocational education and training (VET) at all levels, higher vocational education at universities, and continuing vocational education programs. Vocational education in Korea will also be able to improve the unemployment rate by establishing a system that allows schools and businesses to conduct vocational education and training simultaneously. In particular, it was possible to judge the necessity of 'close consultation between labor, management, and government', which we consider the most important and should lead to in-depth discussion and cooperation for dual education between vocational schools and companies.

This article examines the theory of mutual resonance (感應論) of Dasan (茶山), Jeong Yak-yong (丁若鏞), and Jeungsan (甑山), Kang Il-sun (姜一淳), who lived during the transition to modernity in Joseon. By examining the philosophical thought of Dasan and Jeungsan, which centered on the problem of realizing morality through the resonance (感應) between human beings and Sangje, this article aims to reveal that their religious discussion of resonance, which is differentiated from the rational theory, ultimately strengthens the practice of morality. Dasan and Jeungsan argue that it is difficult to overcome human selfish desires through the mind alone, which aims for moral autonomy, so the recognition of a transcendent being, Sangje, becomes necessary. Since Sangje, the Supreme Being, is always watching over human life, one can examine one's deficiencies with reverence and correct them. In particular, Dasan and Jeungsan reveal that humans and Sangje do not exist independently, but are in touch with each other through the heart, so that moral practice can be actualized in reality. Dasan and Jeungsan do not position humans and the Supreme Being as independent entities, but rather allow them to organically resonate with each other through the mind, enabling individuals to engage in moments of contemplation and reflection at every juncture of choice, unbound by time and space. From this perspective, the resonance theory of Dasan and Jeungsan can be seen to have practical implications for integrating moral practice into everyday life. The thought systems of Dasan and Jeungsan should be understood as embodying the anguish and sincerity of two figures who sought to convey to future generations the path of moral practice that humans must walk, based on a reverent mindset towards the Supreme Being, amidst tumultuous domestic and international circumstances.

MyData is a new entity that strengthens the rights of information subjects through the 'right to data portability' and utilizes data to enable hyper-personalized services using personal information. Korea's MyData system is recognized globally as an outstanding system in that it is creating a new MyData industry by granting the right to information self-determination through the 'right to request data transmission'. Now in its third year, this study evaluates Korea's MyData system from a consumer behavior perspective and identifies issues for improvement. To this end, this study reviewed previous research on the relationship between regulatory policy and consumer behavior to determine the applicability of a consumer behavior perspective in institutional evaluation. In addition, in a study on consumer behavior related to MyData, variables that affect the use of MyData were investigated and evaluation items from a consumer behavior perspective were derived. As a result of evaluating Korea's MyData system from a consumer behavior perspective, it was found that the factors considered important by consumers were appropriately reflected in the system. However, in cases where there are dual values of ease of use and personal information protection, regulatory aspects tend to take priority. Therefore, in order to revitalize the MyData industry, it is essential to implement market-friendly system improvements without compromising consumer rights. This study is differentiated from existing studies in that it attempted to derive a plan for system improvement by combining empirical consumer behavior research and regulatory policy research.
