In this paper, I focus on the performativity thesis introduced and developed by Science and Technology Studies (STS) scholars such as Callon, MacKenzie, etc. since the mid 1990s. The performativity thesis was discussed in economic sociology by STS scholars has been pervaded to other research areas including general economics, accounting, finance and so on. The main idea of the thesis is that economic theories perform, shape, and format economy rather than just describe economy. I show that the thesis is based on the traditional STS ideas such as performativity derived from Merton's self-fulfilling prophecy and the actor-network theory. Although the thesis has been criticised by various researchers from both inside and outside STS, it has provided meaningful implications for understanding economic phenomenon from a viewpoint of STS. Furthermore, reflexive researches for performativity of STS theories can be discussed in the next stage.

실시간 운영 체제(Real-Time Operating System)는 특정 태스크가 정해진 시간 안에 수행될 수 있도록 시간 결정성(Determinism)을 보장하는 운영 체제이다. 실시간 운영테제는 멀티태스킹(Multitasking) 및 ITC(InterTask Communication 혹은 IPC, Interprocess Communication)을 제공한다는 점에서는 일반 운영체제인 Unix$^{TM}$, Linux$^{TM}$, Windows$^{TM}$ 등과 같지만, 시간 결정성을 보장한다는 점에서 일반 운영 체제와 다르다. 또만 실시간 운영 체제를 포함한 임베디드 시스템(Embedded System)은 일반적으로 디지털 카메라, 디지털 TV, DVD 등에서 수행되므로 실행 이미지(Image) 크기가 작아야 한다. 본 논문에서는 실시간 운영체제의 실행 이미지를 줄이면서 시간 결정성을 보장한 수 있도록 메모리 관리 체계를 설계하고 구현한 내용을 설명한다.
