Recently, there is a problem that is most important in constructing buildings and building materials. It is a harmful substance generated in buildings. These harmful substances are CO₂, radon and formaldehyde, volatile organic compounds generated from building materials. These are bad for the human body, may have a negative effect and cause large illnesses such as cancer. Recently built apartments have a high density, so there is a problem that harmful substances do not escape well. As a result, people's interest in indoor air quality is growing and in order to solve this problem and various researches are being conducted on the materials used for concrete pouring to find out how much the materials used adsorb harmful substances. this study uses carbon black as a material that can adsorb these harmful substances. The purpose of this study is to measure the bending strength, compressive strength, and to determine whether the paste containing carbon black can improve indoor air quality.

Recently, due to COV ID-19, many people are spending most of their time indoors. So, there is a rising interest on the indoor air quality in the field of building construction. The main sources for the indoor air pollution are human indoors activity, building materials, living supplies and the polluted air from outdoor. The Korean government has designated 17 indoor air pollutants including fine dust, total airborne bacteria, fungi and carbon dioxide, etc.. Most people are always exposed to assorted bacteria and molds in our daily life, because indoor environment for human, moderate temperature are humidity, it is favourable to the growth of most of bacteria and fungi. Pine needles have an antibacterial effect against bacteria and fungi. In this study, the antibacterial activity against bacteria and fungi was tested by cement matrix using pine needle extract. As a result, the cement matrix using pine needle extract showed antibacterial activities against bacteria, but in the case of fungi, it did not show antifungal activity.

상수도관망의 압력은 물공급 서비스의 질을 나타내는 중요한 인자이다. 압력이 낮으면 물 사용성이 크게 저하되며, 이러한 이유로 보통의 수도사업자는 압력을 중요한 모니터링 변수로 고려하고 있다. 압력을 기반으로 여러 가지 변수를 계산할 수 있지만, 그 중에서도 압력경사(Pressure Head Gradient)는 수요량, 관경, 관의 파괴 등 독립변수 또는 독립요인의 변화에 따른 종속변수로서의 압력 민감도를 나타낸다. 압력경사의 계산은 매우 간단하면서도 활용도가 높다. 따라서, 다양한 종류의 압력경사를 계산하고, 상수도관망 설계, 운영, 관리 목적에 어떻게 사용할 것인가를 연구할 필요가 있다. 본 연구에서는 먼저 관의 상태, 관경, 절점수요량을 독립변수로 하고 이를 변화시켜 그 결과로의 압력종속변수를 계산, 압력경사를 결정하였다. 이를 기반으로, 히트맵을 구축하여 결과를 비교하였다. 그 후 각각의 압력경사에 대한 모듈을 구축하였으며, 개별 압력경사 모듈의 특징을 고려하여 활용방법을 수립하였다.

Sick Building Syndrome (SBS) is an illness symptom such as irritation of eyes, skin eruption and vomit ing in newly constructed buildings. It is mainly due to the harmful gases from the materials installed in building such as Volatile Organic Compounds (VOCs), Semivolatile Organic Compounds (SVOCs), floating bacteria, fungi, fungal spores and viruses, human bioeffluents in many modem buildings. The general ways to improve the Indoor Air Quality (IAQ) are ventilating, utilizing eco-material without harmful gases and reducing or removing harmful gases through additional treatment to the building materials. This study aimed to improve the Indoor Air Quality(IAQ) by applying surface coating on the building materials and to make safe living environments through the analysis of air quality before and after surface coating treatment in buildings.
