일반적으로 현재 많이 사용하는 장기 투영 시스템은 MRI와 CT이다. MRI와 CT는 전자기장을 이용하여 인체를 절개하지 않고 내부 장기를 의사가 볼 수 있도록 한다. 하지만 문제점은 단면적으로 영상을 보여주기 때문에 의사들이 내부 장기를 입체적으로 관찰하기 어려운 문제가 있다. 이 논문에서는 증강현실의 기술을 이용하여 사람의 내부 장기를 현실에 투영 할 수 있는 시스템을 개발한다. 개발한 시스템은 홀로렌즈를 이용하여 환자의 신체위로 내부 장기를 입체 영상으로 보여주며 핸드 모션을 이용하여 내부 장기를 이동시켜 상세하게 관찰이 가능하게 한다.

In Korean terminologies, adjectival terms are rare, and the meaning and function associated with adjectives in Indo-European languages are often realized instead in noun form. However, the rarer adjectival terms we, the more they are used in restrictive and repetitive ways in specialized domains. Thus, it is important to distinguish the different senses of these terms. In this work, focusing on semantic modeling in terminology, we distinguish the different senses of adjectival medical terms by applying lexico-semantic criteria (L'Homme, 2004a) and by classifying the semantic category of the arguments of the adjective (Bae and others, 2002). The result not only contributes to enriching medical terminology, but also empirically demonstrates a method for distinguishing the different senses of adjectival medical terms. In this work, we obtained an average of 1.854 senses for each term. We used the KAIST corpus, composed of medical texts (1,500,000 eojeols), and a group of texts on various subjects (40,000,000 eojeols)

Objectives : This study is to reveal the origin of Mingtangyangfutu in "YiXueRenMen". Methods : This study compares and analyzes it with MingTang diagrams in reference books of "YiXueRenMen", MingTang diagrams and diagrams of bronze statues for acu-moxibustion in those days. Results : The origins of Mingtangyangfutu cannot be found in the citations. The argument that it is copied and simplified from MingTang diagrams in "JinLanXunJing(金蘭循經)" lacks its grounds. As MingTang diagrams in "TongRenShuXueZhengJiuTuJing" and "ZhenJiuJuYing" have less information than it, they were nothing more than references when it drew. Apparel of man, the first acupoint, the last acupoint and orders of acupoints of their meridians in it are different from ones in MingTang diagrams and diagrams of bronze statues for acu-moxibustion. Conclusions : Mingtangyangfutu is not a copied and simplified version of MingTang diagrams in "JinLanXunJing", but is one to add new information for MingTang diagrams in "TongRenShuXueZhengJiuTuJing", "ZhenJiuJuYing", or has a separate rationale (Gajeongdongin(嘉靖銅人) related to at the time.

Sustainability is bound to be an eternal topic for managers who run companies. This sustainability is required not only by managers but also by various stakeholders. As a result, many companies are implementing sustainable management and are actively utilizing ESG, which has become a hot topic since 2020. In this study, we examined sustainable management and ESG, focusing on LX Hausys, which was the first in the interior industry to write a sustainable management report and received an ESG evaluation grade A for five consecutive years. As LX Hausys promoted sustainable management, it naturally focused on ESG management. As a result of meeting with LX Hausys HR executives and ESG managers for this study, ESG is not accepted as a new one. Rather, he emphasized that there is no need to approach this approach to ESG with grandeur and difficulty. This approach is consistent with the argument that ESG is a true approach to sustainable growth, not a management strategy based on the times. Like LX Hausys, ESG management can be consistently and continuously performed when implementing ESG strategies based on the resources and capabilities of companies, which can be seen as leading to corporate sustainability. This ESG management will be the right way to create a permanent company.

With the proliferation of social media, it has become easier for people to spread rumors online, which can aggravate the issues arising from online rumors. There are many individuals and organizations that are adversely affected by malicious online rumors. Despite their importance, there has been little research into why and how people spread rumors online, thus inhibiting the understanding of factors that affect the spreading of online rumors. With attention seeking to address this gap, this paper draws upon the dual process theory and the de-individuation theory to develop a theoretical model of factors affecting the spreading of an online rumor, and then empirically tests it using survey data from 211 individuals about a specific rumor. The results indicate that the perceived credibility of the rumor affects the individuals' attitudes toward spreading it, which consequently affects the rumor spreading behavior. Vividness, confirmation of prior beliefs, argument strength, and source credibility positively influence the perceived credibility of online rumors. Finally, anonymity moderates the relationship between attitude toward spreading online rumors and the spreading behavior.

IT education can be summarized as persuading the educatee to accept IT. The persuasion is made by delivering the messages for how-to-use and where-to-use to the educatee, which leads formulation of a belief structure for using IT. Therefore, message based persuasion theory, as well as IT acceptance theories such as technology acceptance model(TAM), would play a very important role for explaining IT education. According to elaboration likelihood model(ELM) that has been considered as one of the most influential persuasion theories, people change attitude or perception by two routes, central route and peripheral route. In central route, people would think critically about issue-related arguments in an informational message. In peripheral route, subjects rely on cues regarding the target behavior with less cognitive efforts. Moreover, such persuasion process is not a one-shot program but continuous repetition with feedbacks, which leads to changing a belief structure for using IT. An educatee would get more knowledge and experiences of using IT as following an education program, and be more dependent on a central route than a peripheral route. Such change would reformulate a belief structure which is different from the intial one. The objectives of this study are the following two: First, an identification of the relationship between ELM and belief structures for using IT. Especially, we analyze the effects of message interpretation through both of central and peripheral routes on perceived usefulness which is an important explaining variable in TAM and perceived use control which have perceived ease of use and perceived controllability as sub-dimensions. Second, a longitudinal analysis of the above effects. In other words, change of the relationship between interpretation of message delivered by IT education and beliefs of IT using is analyzed longitudinally. For achievement of our objectives, we suggest a research model, which is constructed as three-layered. While first layer has a dependent variable, use intention, second one has perceived usefulness and perceived use control that has two sub-concepts, perceived ease of use and perceived controllability. Finally, third one is related with two routes in ELM, source credibility and argument quality which are operationalization of peripheral route and central route respectively. By these variables, we suggest five hypotheses. In addition to relationship among variables, we suggest two additional hypotheses, moderation effects of time in the relationships between perceived usefulness and two routes. That is, source credibility's influence on perceived usefulness is decreased as time flows, and argument quality's influence is increased. For validation of it, our research model is tested empirically. With measurements which have been validated in the other studies, we survey students in an Excel class two times for longitudinal analysis. Data Analysis is done by partial least square(PLS), which is known as an appropriate approach for multi-group comparison analysis with a small sized sample as like this study. In result. all hypotheses are statistically supported. One of theoretical contributions in this study is an analysis of IT education based on ELM and TAM which are considered as important theories in psychology and IS theories respectively. A longitudinal analysis by comparison between two surveys based on PLS is also considered as a methodological contribution. In practice, finding the importance of peripheral route in early stage of IT education should be notable.

본 연구의 목적은 수용자의 인지정교화 가능성과 뉴스 프레임 효과의 관계를 분석하는 것이다. 이를 위해 서로 다른 프레임과 메시지 특성이 적용된 기사를 수용자에게 노출시키는 실험을 통해서 뉴스 프레임 효과가 수용자의 인지정교화 수준에 따라 어떻게 변화하는지를 살펴보았다. 연구 결과, 수용자의 이슈에 대한 관여도가 높을수록 뉴스 프레임에 대한 동조화 정도가 높은 반면, 수용자가 비평적으로 사고하는 성향이 강할수록 뉴스 프레임에 대한 동조화는 적거나 역방향으로 나타나고 있다. 따라서 수용자 요인 중에서 비평적 사고를 즐기는 성향은 높은 수준의 인지정교화를 결정짓는 요인이긴 하지만, 반드시 프레이밍 효과로까지 이어지는 요인은 아니었다. 관여도가 낮은 이슈일수록 수용자들은 주변경로로 정보를 처리하는 경우가 많은 것으로 확인되었다. 메시지 특성 변인으로 논증과 단서의 양이 많을수록 프레임에 대한 동조화 정도가 높은 것으로 확인되었다. 논증과 단서의 양이 적을수록 수용자들은 주변경로를 통해 정보를 처리하는 경우가 많았다. 관여도의 경우, 고관여 이슈에서는 단서보다 논증의 양에 따라서 프레이밍 효과가 결정되는 반면, 저관여 이슈에서는 단서의 양에 따라서 프레이밍의 효과의 차이가 나타나고 있다.

The information society is characterized by rapidly increasing and changing information. Traditional models of learning and instruct on have emphasized forms of mastering the information in content domains. Storing information and being able to recall it has been central to formal education. But it is no longer possible to master content domains. This paper discusses constructivism as a shifting paradigm for educational research and practice in information society. Constructivism provides an alternative epistemological base to the objectivist tradition. Constructivism holds that there is a real world that we experience. However, the argument is that meaning is imposed on the world by us, rather than existing in the world independently of us. Meaning is seen as rooted in experience. The experience in which an idea is embedded is critical to the individual's understanding of that idea. From the constructivist perspective, learning is not a stimulus-response phenomenon. It requires self-regulation and the building of conceptual structures through reflection and abstraction. Problems are not solved by the retrieval of rote-learned right answers. The effective motivation to continue learning can be fostered by leading students to experience the pleasure that is inherent in solving problems chosen as one's own. Constructivism requires the change of the teacher's role from a knowledge transmitter to a coach or facilitator of student's understanding. Constructivist teachers inquire about students' understanding of concepts before sharing their own understandings of those concepts, and encourage students to engage in dialogue, both with them arid with one another. In Korea, the educational reform called open education has been spreading through out the country. There should be a paradigm shift in learning and instruction from objectivism to constructivism for better educational reform in Korea.
