흥분제(Psychostimulants)에 대한 신경생물학 측면의 고찰 -Methamphetamine 남용을 중심으로
이태경,존 E 그랜트,김석원,오동열,Lee Tae Kyung,Jon E. Grant,Kim, Suck Won,Oh Dong Yul 대한임상독성학회 2003 대한임상독성학회지 Vol.1 No.1
Methamphetamine (MA) is a major drug of abuse in Korea. Currently preliminary evidence suggests that MA dependence may cause long-term neural damage in human. Repeated exposure to psychostimulants such as methamphetamine results in behavioral sensitization, a paradigm thought to be relevant to drug craving and addiction in human. Sensitization alters neural circuitry involved in normal processes of incentrive, motivation, and reward. However the precise mechanism of this behavioral sensitization has not yet been fully elucidated. Repeated use of high dose MA causes neurotoxicity which is characterized by a long-lasting depletion of striatal dopamine (DA) and tyrosin hydroxylase activity of DA, DA-transporter binding sites in the striatum. The loss of DA transporters correlates with memory problems and lack of motor coordination. DA fuels motivation and pleasure, but it' s also crucial for learning and movement. This selective review provides a summary of studies that assess the neurobiological mechanisms of MA.

The chemical mechanical planarization (CMP) is a process of physically and chemically polishing the semiconductor substrate. The planarization quality of a substrate can be evaluated by the within wafer non-uniformity (WIWNU). In order to improve WIWNU, it is important to manage the pad profile. In this study, a device capable of non-contact measurement of the pad thickness profile was developed. From the measured pad profile, the profile of the pad surface and the groove was extracted using the envelope function, and the pad thickness profile was derived using the difference between each profile. Thickness profiles of various CMP pads were measured using the developed PMS and envelope function. In the case of IC series pads, regardless of the pad wear amount, the envelopes closely follow the pad surface and grooves, making it easy to calculate the pad thickness profile. In the case of the H80 series pad, the pad thickness profile was easy to derive because the pad with a small wear amount did not reveal deep pores on the pad surface. However, the pad with a large wear amount make errors in the lower envelope profile, because there are pores deeper than the grooves. By removing these deep pores through filtering, the pad flatness could be clearly confirmed. Through the developed PMS and the pad thickness profile calculation method using the envelope function, the pad life, the amount of wear and the pad flatness can be easily derived and used for various pad analysis.
Syntax directed Compiler for Subset of PASCAL
이태경(Lee Tae Kyung) 한국정보과학회 1977 정보과학회논문지 Vol.4 No.2
The PM language is a Compiler writing language which syntax-directly translates a high level language into a intermediate language of matrix form. The PM assembler translates the PM language into recursive subroutines which test input strings or output intermediate terms or call another subroutines. A large subset of PASCAL compiler was written in the PM language.

A 61-year-old female had neurofibromas situated on the right side of upper trunk, shoulder and neck in the distribution of dermatomes C3 and C4(right), which developed 3 years ago. There were not cafe-au-lait spots, axillary frecklings, or Lisch nodule (iris pignented hamartoma). Biopsy specimen showed collagenous wavy fibrils among which spindle-shaped and round cells were embedded as seen in the typical neurofibroma. This case was considered to be a segmental form of von Recklinghausen's disease.
