美國後殖民研究學者 Mary Louise Pratt 於1991年提出「接觸地帶 contact zone」的概念，一個帶有空間及社交意涵的詞彙，以探討征服者與被征服者之間文化的相遇、衝突、與協調(Mary Louise Pratt,1991)。而在 COVID-19 疫情時代，病毒快速擴散，成為全球化下的新征服者，快速複製、組裝的建築系統所形成的接觸地帶成為這個時代回應人與人之間日常活動的建築介面。

本研究以台灣經歷過多次大規模感染後進入與病毒共存的時代為背景，並以社交活躍的市場為研究對象，旨在設計一種可拆卸、組裝的氣流遮罩單元，以控制和引導建築內氣流的流速和流向。使我們能夠在建立防疫措施的同時並改善市場環境。

研究內容以氣流研究遮罩單元作為市場模組單元的實驗對象，並使用CFD軟體進行氣流可視化和設計發展。為了減少市場內部的氣流停滯，重新審視在疫情爆發和後疫情時代的設計系統樣貌。通過實驗結果調整模型原型，並使用1/20比例模型和CFD模擬進行驗證，以確定研究的可行性。

在確立研究可行性後，本研究提出「異質系統」之設計概念，指的是在接觸地帶的系統架構內，通過拆解和組裝不同的氣流非接觸建築原型來探索市場的核心面向-開放性和安全性。期望藉由此系統提出對於接觸地帶的非接觸解決方案，並應對疫情爆發和後疫情的時代。

In the era of COVID-19, where the virus rapidly spreads and becomes the new conqueror of globalization, the contact zone formed by quickly replicating and assembling building systems has become the architectural interface that responds to daily activities between people.

This study is based on Taiwan's experience of several large-scale infections and entering an era of coexistence with viruses. The research focuses on social and active marketplaces. It aims to design a detachable and assemblable air flow shielding unit that controls and guides the airflow speed and direction inside buildings. This enables us to establish epidemic prevention measures while improving the market environment.

The research focuses on the design and development of a removable and reconfigurable airflow barrier unit in social and active markets to control and direct the airflow velocity and direction within the building. The experiment uses CFD software for airflow visualization and design development, with the aim of reducing the airflow stagnation in the market and re-examining the design system's appearance during and after the epidemic. The model prototype is adjusted based on the experimental results and verified using a 1/20 scale model and CFD simulation to confirm the feasibility of the research.

After establishing the feasibility of the study, this research proposes the design concept of a "heterogeneous system," which refers to the exploration of the core aspects of market openness and safety through the disassembly and assembly of different non-contact building prototypes for airflow in the system structure of the contact zone. The goal is to propose non-contact solutions for the contact zone and address the outbreak and post-epidemic era.
