The purpose of this study is to research source of soil which is available for non-detergent course, and to develop optimum non-detergent course of washing machine for water soluble soil. The water soluble soil such as grape juice, soy bean paste and soy sauce were easily removed from the fabric but the oil soluble soils such as sesame oil and steak sauce were insurfficiently removed in washing solution without detergent. In the absence of detergent, amount of residual soils increased linearly with increasing number of soiling and washing. To search optimum conditions of washing for non-detergent course, the effect of temperature, washing time and washing method on detergency of soil in non-detergent washing solution was examined. The optimum washing temperature and washing time for non-detergent course were about $40^{\circ}C$, and 7 minutes, respectively. And in the non-detergent washing solution, midterm drain-resupply of water during washing process was good for removal of water soluble soil.

Surfactants which have ability to decrease surface tension through surface activation between the interfaces are used as essential major raw materials for detergents and cosmetics. Typical synthetic detergents such as EO (ethylene oxide), LAB (linear alkylbenzene) are made from chemical surfactant derived from petrochemicals, therefore, they are responsible for major environment contaminations and ecosystem destruction, especially of rivers and also cause atopic dermatitis through strong skin stimulus of these small molecular's powerful permeability and lead to cancers if they get into organs through capillary. Now worldwide interest is increasing to develop new natural surfactants and biosurfactants as ecological, biodegradabl, harmless and multi-functional new amphiphillic materials which replace these synthetic surfactants.

This study was conducted to seek optimum concentration and treatment time of fermented rice water (Rizen) to disinfect food-borne bacteria in kitchen towel. $2.65\;log_{10}cfu/g$ of E. coli was reduced when double or triple diluted fermented rice water was treated during 2 hours. In case of concentrated fermented rice water, crude and double diluted solutions showed complete sterilization after 2 and 5 hours, respectively. On the other hand, triple, quadruple, quintuple diluted solutions needed 24 hours for complete sterilization. The effect of fermented rice water as a disinfectant was compared with water, detergent and chlorine treatment against E. coli and S. Typhimurium contaminated in kitchen towel. The initial number of E. coli in untreated kitchen towel were $5.0\;log_{10}cfu/g$ and were decreased to 4.32, 3.70 and 3.02 by treatments of water, detergent and chlorine, respectively. The double and triple diluted fermented rice water and double diluted concentrated fermented rice water also reduced the E. coli in kitchen towel to 2.43, 2.30 and $1.88\;log_{10}cfu/g$, respectively. The initial number of S. Typhimurium in untreated kitchen towel were $4.80\;log_{10}cfu/g$ and were decreased to 4.12, 3.58 and 2.81 by treatments of water, detergent and chlorine, respectively. The double and triple diluted fermented rice water and double diluted concentrated fermented rice water also reduced the E. coli in kitchen towel to 2.14, 2.03 and $1.59\;log_{10}cfu/g$, respectively. Consequently, the fermented rice water is thought to be a good disinfectant to reduce food-borne bacteria like E. coli and Salmonella contaminated in kitchen towel.

Since the sub-prime mortgage crisis from the US in 2008, Korean housing market has plummeted. However, Korean local lease contract, Chonsei, price has been increasing. This increase of Chonsei price can be a threat to the low-income people because most of them prefer to live at the house with a Chonsei contract. In order to solve this problem, the Korean Government implemented several Chonsei policies to secure low-incomers' residence by decreasing the price of Chonsei; however, due to the lack of understanding on housing and Chonsei market, Korean government policy seemed to fail on getting effective results. In the housing and Chonsei market, there are many stakeholders with their own interest, hence, simple thoughts about housing and Chonsei market, such as more house supply will decrease house price, would not work in a real complex housing market. In this research, we suggests system dynamics conceptual model which consists of causal-loop-diagrams for the Chonsei market as well as the housing market. In addition, we tries to explain why the policy did not work effectively using the examples from the government's past measures. In results, Chonsei price has its own homeostasis characteristic and different price movement with housing price in the short and long term period. Unless government does not have a structural causation mind in implementing policies in the real estate market, the government may not attain intended effectiveness on both markets.
