현대의 PC 환경에서 사용자 인터페이스의 변화는 계속하여 발전할 것으로 기대된다. HCI 전용 인터페이스는 종래의 CLI; Command Line Interface의 시대에서 MS-Windows 기반의 Graphic User Interface의 시대로 전환되어 왔으며, 가까운 미래에는 NUI; Natural User Interface의 시대로 도래함은 부정할 수 없는 현실이다. 미래에는 전통적인 표준 입력 장치인 키보드, 마우스를 탈피하여 새로운 개념의 입력 장치들이 개발되고, 터치 방식과 같이 인간의 직관적 인지능력을 흉내 낸 인터페이스로 발전할 것이다. 본 논문에서는 NUI의 사례 연구로서 닌텐도 WiiRemote를 Bluetooth와 함께 PC에 연동하여 차세대 인터페이스인 PC Controller를 설계, 사람 제스처를 통한 자연스런 한글입력의 가능성을 제안한다.

Intergeneric hybrids formed between Aspergillus oryzae var oryzae and Penicillium verruculosum F-3 were obtained by nuclear transfer technique. Several auxotrophic mutants isolated fromconidio-spores of the two strains mutagenized with ultraviolet and N-methyl-N-nitrosoguanidine. Optimal conditions for formation of intergeneric hybrids were investigated. Frequencies of hybrid formation by nuclear transfer were 3$\times $10$^{-5}$ $~$1$\times $10$^{-5}$. From observation of genetic stability, conidial size, DNA content, nuclear stain, it was suggested that their karyptypes are aneuploid. The hybrid posses the 1.3$~$2.2 fold higher amylase activities than those of parental strains. It was also revealed that some hybids had different isozyme patterns compared to those of parental strains by amylase activity assays.

Carbon-fiber-reinforced plastic (CFRP) composite materials have been widely used in various industrial fields because the design variables can be adjusted according to the application of the required structure. Thermosetting and thermoplastic resins are used as the base materials of CFRP composites for the lightweight construction of automotive components. Thermoplastics have several advantages such as no curing and recyclability compared to thermosetting resin. In this study, CFRP composites were made using the Long-Fiber Thermoplastic-Direct (LFT-D) process. The LFT-D process includes an in-line production system that directly impregnates a thermoplastic resin, extrudes the composite material, and molds it. This process increases the strength and decreases the molding time. The tensile strength characteristics on the mechanical properties of CFRP were analyzed according to the parameters of LFT-D based on thermoplastics. To analyze the properties of CFRP, the specimens were prepared based on the tensile test standard ASTM 3039 of composite materials.

The purpose of this study is to understand the required concept in the architectural competition for public library and its application in design process. The research is based on the 27 design guideline of architectural competition for public library from 2009 to 2013 and, as a case study, the project for the Chungcheongnam-do Provincial Library, the prize winner in 2014. Three required concepts; symbolism, function, and sustainability, are categorized through the analysis on the design guideline of 27 competitions and are identified. Symbolism is expressed by landmark forms based on the local characteristics. The function of public library means to provide services to everyone, regardless of age, race, gender, religion etc., as a local community. Sustainability is related to passive architecture for the maintenance and management of buildings. These three concepts for public library applied on the design process of Chungcheongnam-do Provincial Library and design elements in each process are categorized in three concepts. The results shows not only how closely the locality and a user are related, but also the changes in the appearance of a public library as time passed.

Recently the architectural paradigm have been changing into eco-friendly architecture as an sustainable architecture. This social background encourages the development of various methods of building applicable for eco-friendly buildings in architectural design. Among them, passive architecture is an design approach for eco-friendly design that contrasts with technology-based methods through MEP for renewable energy. This study researches the Passive Architectural Design methodology with two points of view; Passive Architectural Design Techniques as a guideline, which defines the elements to consider for passive architecture, and the project of Sejong Municipal Public Library as a case, which is to analysis the architectural design process. The purpose of this study is to propose an eco-friendly public building based on the methodology which is suitable for passive architectural design. Finally, this study suggests that the eco-friendly public building design for passive architecture should consider from the early step of design process, such as concept and building form etc. What is important for the passive architecture is not how much building can produce the natural energy but how less building consumes it to maintain.

The classroom is a learning space where students live mainly in school, and it is the most important space within the entire educational space of the school. Although our educational system has been trying to revise and change the curriculum many times, it still does not provide space for the educational concept of modern society. The impact of the abolished 'school facility standard design' in 1992 is still evident in the design of school facilities at present. Specifically, the uniformity of the educational space, the rigid boundary of the classroom unit, the blockage between the school facility and the outside, and the separation due to the break of the inner and outer spaces. In the future, we need a flexible space that can contain the contents of the future education, and it is necessary to study the composition and type of educational space that can escape uniformity and spatial breakdown. In this paper, we analyze the successful cases of Irvine school facilities and examine the type and composition of classroom space, and it will be a task to find the direction and change of thinking about our educational space.

Today, the paradigm of education is changing from teacher-centered, facility-centered, supplier-centered to student-centered, people-centered, and user-centered. In 2019, the Ministry of Education promoted the school space innovation project to provide a school space as a balanced life space, such as learning, play, and rest, through educational activities led by students, who are the leaders of the future society. Based on this, Incheon Metropolitan City Office of Education prepared a manual for practice while carrying out a project to build a future classroom. In those projects 'user participatory design' is applied as a new design approach and facilitators play an important role as experts in the process of user participatory design. However, it is different from the guidelines by the Ministry of Education in terms of facilitator role; facilitator in Incheon's future classroom projects can be in charge of designer part. This was possible because the design scope was limited to the classroom space and the construction permit work was not applied, and the Incheon Metropolitan City Office of Education seems to be able to successfully implement the plan derived through 'user participatory design' under the responsibility of the facilitator. However, this may be considered to be inconsistent with the basic purpose of the school space innovation project. In the case of the school unit project, it is considered that more systematic supplementation is necessary.

Characterization and electron microscopic visualization of the plasmid and the gene expression of Escherichia coli were carried out. Transcriptional units of active structural genes were observed after lysis of Escherichia coli cells. The ribosomes attached to the E. coli genome on mRNA molecule as polyribosomes. From this gradient of polyribosome length, we estimated location of mRNA synthesis initiation site. In this experiment, a granule is ofen present which may correspond to a RNA polymerase at the promoter site. pOX1, pOX7, pOX7A, $pOX7{\Delta}1$, pSTP36, pSTP21, pBR322, and pJH12 were visualized by way of electron microscope, and their estimated sizes were determined to be $5.70{\pm}0.08{\mu}m,\;2.15{\pm}0.10{\mu}m,\;2.14{\pm}0.12{\mu}m,\;7.39{\pm}0.08{\mu}m,\;4.03{\pm}0.04{\mu}m,\;1.50{\pm}0.03{\mu}m\;and\;1.25{\pm}0.09{\mu}m$ respectively. One micrometer of measured length corresponded to about 3.0 Kb. Mica-press adsorption method that allows selectivs visualization of the plasmid DNA released in situ from the bacterial cell is rapid and useful for visualization of plasmids. The released plasmid DNA was adsorbed preferently on mica in a divalent cation-free solution. Miller chromatin-spreading method was useful to observe the plasmid and transcripts. BAC method and cytochrome C monolayer were useful to observe the plasmid DNA. Our ability to visualize ultrastructural aspects of the expression of E. coli has given us a unique tool with which to study the regulation the level of an individual gene.
