Business still relies heavily on pen and paper for legal reasons or convenience. The handwritten document is to be converted into digitalized document for IT system to manage and process in real time. Because the previous document digitalization systems convert the handwritten documents into digitalized documents by scanning and post-processing the documents, it is difficult to seamlessly proceed the work process. This paper proposes the LiveForm, a framework for digitalizing handwritten document using digital pen and handwriting recognition technology. To prove the applicability of the proposed LiveForm, we also implement a LiveForm based service in industrial gas distribution process and analyze effects of the system. The LiveForm generates the same digital image as the handwritten document by writing up the paper with absolute coordinates by digital pen and converts the handwriting data to digital text to insert the information into back-end system. The LiveForm based system eliminates scanning for document digitalization and data input with keyboard into back-end system in paper-based information gathering. Therefore, it is possible for the LiveForm to improve work process in various business areas.

With the transition of archaeological recording method's transition from analog to digital, the 3D scanning technology has been actively adopted within the field. Research on the digital archaeological digital data gathered from 3D scanning and photogrammetry is continuously being conducted. However, due to cost and manpower issues, most buried cultural heritage organizations are hesitating to adopt such digital technology. This paper aims to present a digital recording method of relics utilizing open-source software and photogrammetry technology, which is believed to be the most efficient method among 3D scanning methods. The digital recording process of relics consists of three stages: acquiring a 3D model, creating a joining map with the edited 3D model, and creating an digital drawing. In order to enhance the accessibility, this method only utilizes open-source software throughout the entire process. The results of this study confirms that in terms of quantitative evaluation, the deviation of numerical measurement between the actual artifact and the 3D model was minimal. In addition, the results of quantitative quality analysis from the open-source software and the commercial software showed high similarity. However, the data processing time was overwhelmingly fast for commercial software, which is believed to be a result of high computational speed from the improved algorithm. In qualitative evaluation, some differences in mesh and texture quality occurred. In the 3D model generated by opensource software, following problems occurred: noise on the mesh surface, harsh surface of the mesh, and difficulty in confirming the production marks of relics and the expression of patterns. However, some of the open source software did generate the quality comparable to that of commercial software in quantitative and qualitative evaluations. Open-source software for editing 3D models was able to not only post-process, match, and merge the 3D model, but also scale adjustment, join surface production, and render image necessary for the actual measurement of relics. The final completed drawing was tracked by the CAD program, which is also an open-source software. In archaeological research, photogrammetry is very applicable to various processes, including excavation, writing reports, and research on numerical data from 3D models. With the breakthrough development of computer vision, the types of open-source software have been diversified and the performance has significantly improved. With the high accessibility to such digital technology, the acquisition of 3D model data in archaeology will be used as basic data for preservation and active research of cultural heritage.

The right to be forgotten is a world-wide issue after the decision of the European Court of Justice which accepted that right. This essay discusses about the guide lines for protecting the right to delete, a category of the right to be forgotten. I classified those guide lines as follows : (1) sensitiveness of the personal information, (2) offensiveness to reasonable and ordinary people, (3) intention of writing the article, (4) value of historical record, (5) importance of privacy comparing with right to know with time flow, (6) public figure, (7) article based on fact or opinion. To effectively protect right to be forgotten and delete, we have to consider Privacy Impact Assessment, using blind system, unification of multiple institutions, and reforming press arbitration system.

The constraints of printed text have been lifted through developments in computer technology which has been identified as a revolutionary force. Hypertexts can be simply defined as electronic text that is found online, in a non-linear manner. In contrast to traditional printed texts, electronic writing depends upon an emergent technology, which is still subject to transformation. Unfortunately more research is needed on the experiences readers have when reading documents in hypertext formats for the purpose of knowledge retention. This study is to research the contrast between the traditional printed texts and hypertexts. Other areas where the literature has been relatively silent will be explored such as the experiences subjects have in reading hypertexts, and printed texts. It was clearly founded that the format of text does significantly influence the recall comprehension level of readers in the Printed Text and Hypertext Groups.

Recent statistics revealed that with the crisis of humanities, the unemployment rate of the students majoring in this field of study is very high. Considering the seriousness of current situations, the government announced 'Plan to Help Students Majoring in Humanities Find Job.' This study confirmed that the government's policy for those from the department of humanities is valid and reasonable. However, the convergence of humanistic imagination and engineering thoughts could generate some side effects. Therefore, this study suggested a direction for humanistic convergence education to help these students get the career they want. In this study was investigated methodology which can maximize the efficiency of digital storytelling through microscopic convergence instead of macroscopic convergence. In addition, this study proposed that an inter-disciplinary convergence system-based project would be the best solution to nurture convergence-oriented talents in humanities.
