As part of the research on cement composites using cellulose nanocrystal (CNC) aqueous solution instead of general water, this study produced high-toughness cement composites reinforced with flax and steel fibers to improve the tensile deformation capacity, assessing the isothermal conduction calorimetry analysis, drying shrinkage, and strength characteristics. The mixing amount of CNCs was 0.4, 0.8, and 1.2 vol.% by volume of cement, and an aqueous solution was prepared using the ultrasonication dispersion method. When comparing the results of the experiment according to the CNC mixing ratio, CNCs at 0.8 vol.% led to an improvement in the shrinkage rate and mechanical performance compared with the plain specimen.

기존의 유닉스 시스템에서는 모든 장치의 구동기가 커널 내부에 구현되어 있다. 따라서, 새로운 장치를 지원하기 위한 구동기를 추가하거나 기존의 구동기를 변경할 경우 커널 내부의 수정 작업이 불가피하다. 일반적으로 유닉스 시스템에서는 커널내 부의 수정 작업이 매우 어렵다. 본 논문에서는 이러한 어려움을 극복하기 위한 방법 으로써 사용자 수준의 단말기 구동기 모델을 제시한다. 제시한 모델의 기본 개념은 단말기 구동기를 사용자 수준의 서버로 구현함으로써 새로운 단말기 구동기의 동적 재구성을 제공하는 것이다. 제시한 모델의 타당성을 검증하기 위해 사용자 수준의 단말기 구동기를 SunOS 와 Linux 환경에서 구현하고, 그 성능을 평가하였다. In the conventional UNIX system, the all device driver realized in the kern el. Hence, whenever we want to add a new device driver or change the existin g device driver, the modification of kernel is unavoidable. Generally, it is very difficult to modify the kernel codes.As a method of overcoming this difficulty, a TTY device driver model of user-level is presented in this paper. The basic concept of this model is providing a dynamic reconfiguration of TTY device driver by realizing a user-level server process for TTY device driver. In order to verify the proper y of this model, a prototype of TTY device driver has been realized in the SunOS and Linux environment and evaluated its performance.

Tuberculosis of the retropharynx is extremely rare. The diagnosis is frequently delayed because of its anatomical location and atypical symptom. It would be crucial to consider tuberculosis infection as a possible source of abscess and should be mindful about the tests to diagnose it. We experienced a 23-year-old man with retropharyngeal abscess caused by tuberculosis presenting hypernasality and hoarseness in the throat. In this article, we reviewed the etiology, diagnosis, and treatment of this case, with a review of literatures.

Hypersonic vehicles over Mach 5 need active cooling or thermal management systems to resolve excessive heating problems on their fuselage and engines. Endothermic fuels are widely used these days not only for the energy source but also for a heat sink. Therefore, fuel supply systems of hypersonic vehicles should be mainly composed of adiabatic fuel storage tank, cooling systems for the airframe and engine/nozzle, and fuel supply/injection systems in high pressure, high temperature, and high fuel flow rate conditions. This paper describes a conceptual design process of a hypersonic fuel supply system in order for designing a layout of the system, and identifying components and their specification requirements.

We employed in-situ spectroscopic ellipsometry(SE) and imaging ellipsometry(IE) to study the interaction of water and photoresist(PR) in 193 immersion lithography. Real time measurement of SE showed thickness increase when PR was immerged in water indicating swelling effect. From the temporal evolution we could observe its reaction-limited behavior. Meanwhile, IE could identify the modification of PR surface by contact of water even for a short period of a second.
