적외선 열 영상 system에서 가장 핵심이 되는 BSCT 320X240 IRFPA를 구현하였다. 검출기 module은 두 개의 부분, 즉 적외선 감지 pixel의 array와 감지된 신호를 읽어내는 ROIC로 구성된다. 50-${mu}m$의 pitch와 95-%의 fill-factor를 만족하도록, laser scriber공정과 10-${mu}m$ 크기의 ball을 갖는 micro bump공정을 적용하였다. ROIC는 선택된 신호를 읽어서 순차적으로 출력하게 설계되었으며, 단일 transistor amplifier, HPF, tunable LPF 그리고 clamp circuit를 삽입하여 SNR이 개선되도록 설계하였다. Detector와 ROIC의... -

This study was conducted to assess time-sensitive magnetic resonance (MR) changes in canine blood using low-field MR. Arterial and venous blood samples were collected from eight healthy beagle dogs. Samples were placed in 5-mL tubes and imaged within 3 hours of collection at 1 day intervals from day 1 to day 30. The following sequences were used: T1-weighted (T1W), T2-weighted (T2W), fluid-attenuated inversion recovery (FLAIR), short tau inversion recovery (STIR), and T2-star gradient-echo... -
Imaging evaluation of the liver using multi-detector row computed tomography in micropigs as potential living liver donors

The shortage of organ donors has stimulated interest in the possibility of using animal organs for transplantation into humans. In addition, pigs are now considered to be the most likely source animals for human xenotransplantation because of their advantages over non-human primates. However, the appropriate standard values for estimations of the liver of micropigs have not been established. The determination of standard values for the micropig liver using multi-detector row computed tomography... -
Effects of synthesis pressure conditions on the preparation of graphene-like carbonaceous materials from organic liquid precursors by a solvothermal method

Carbon materials with at least one dimension of 1?100 nm are called carbon nanomaterials. A significant body of previous research in physics, chemistry and biology has demonstrated that the properties of nano-composites are significantly different than those of the bulk materials [1]. Some unique phenomena, such as the quantum tunneling effect, and surface effects, have also been observed, and attributed to the large surface area and small size of the carbon nanomaterials. It has been reported... -
Pre-ischemic Treatment with Ampicillin Reduces Neuronal Damage in the Mouse Hippocampus and Neostriatum after Transient Forebrain Ischemia

Ampicillin, a Ղ-lactam antibiotic, has been reported to induce astrocytic glutamate transporter-1 which plays a crucial role in protecting neurons against glutamate excitotoxicity. We investigated the effect of ampicillin on neuronal damage in the mouse hippocampus and neostriatum following transient global forebrain ischemia. Male C57BL/6 mice were anesthetized with halothane and subjected to bilateral occlusion of the common carotid artery for 40 min. Ampicillin was administered...
