Chinese is the most spoken language in the world. However, because Chinese is a hieroglyphic language, using Chinese in a digital environment is very inconvenient. Chinese users are using Pinyin for Chinese input, but the phonetic representation of the Latin alphabet is not good. Hunminjeongeum has an excellent phonetic representation which can improve Chinese usage in digital environment. Therefore, it is possible to improve the use of Chinese by Chinese users in digital environment and to help Korean users who are learning Chinese. Therefore, this paper proposes a Chinese input method using Hunminjeongeum. In addition, we develop an input software using this input method and verify its effectiveness by evaluating usability.

Electronic environment affects archival community to a great extent. It redefines virtually every stage of archival management form creation to current and semi-current use, to appraisal, and to preservation of records. Faced with the problems caused by ever increasing electronic records, the community is forced to reconsider traditional concepts, approaches, methodologies, even the basic paradigm embedded in archival theory and practice. The present paper discusses the need to reexamine principles and techniques of archival management in the light of digital environment. It also urges archives and archival institutions, the archival profession, or the archival community at large, to participate in this critical enterprise. Success in this endeavor will, eventually, pave the road toward creating, organizing, providing access to, preserving reliably and authentically electronic records and designing proper system for the societal collective memory in recorded digital information.

As the design environment of domestic infrastructure facilities shifts from a traditional co-work office system to a virtual digital co-work office, a CDE collaboration platform is required to build a digital co-work office suitable for the domestic design environment. In addition, a number of large multinational projects requiring collaboration from domestic and foreign construction companies are ordered, and procedures for performing tasks based on international standards such as ISO 19650 are required, so preparation for domestic designers is required. Therefore, this study aims to derive CDE requirements for the development of an ISO 19650-based CDE collaboration platform suitable for domestic design environments, and derived Korean CDE requirements based on ISO 19650 series and overseas CDE cases.
