The purpose of this study was to understand characteristics of groups vulnerable to extreme heat and to reduce mortality caused by high temperature. For this purpose, relationship between socioeconomic factors and mortality-threshold temperatures were studied. The study area was limited to Seoul (South Korea) and climate data from 2000 to 2010 was used. Our results indicate that mortality-threshold temperatures for regions with a high proportion of aging population and a low proportion of aging population are $27.6^{\circ}C$ and $27.9^{\circ}C$, respectively. It was also found that a relative size of welfare dependant population did not affect mortality-threshold temperatures. However, regions with a high proportion of aging and welfare dependant population experienced $0.7^{\circ}C$ lower mortality-threshold temperature than other regions. This implies that low income and older people in Seoul are more easily affected by high temperature. Thus, this study suggests that it needs a policy targeted to low income and aging population to decrease mortality rate caused by extreme heat.

This work is concerned with a plan for preventing accidents of CO gas leak from gas boilers, involving the enforcement of installations of both CO alarm system and condensing boilers, and financial support of government grants. If amongst 1,460,000 beneficiaries of basic livelihood security, one million households in use of gas boilers receive 3-year support of 200,000 won, the difference of prices between common and condensing boilers, the government grants would be 2,000 billion won. If 3 million common householders are in 3-year support of 100,000 won, government grants would be 3,000 billion won. Therefore, 3-year grand total of government grants would be 5,000 billion won. Finance for government grants can be purveyed from energy saving; yearly 2,000 billion won of energy saving by enforcing to replace one million existing boilers with condensing boilers, leading to 2 trillion won of energy saving for 10 years. In this way, 6,000 billion won of 3-year grand total of government grants for CO alarm system and condensing boilers can be purveyed. The rest amount would be fundraised for energy savings. We claim that our proposal can make an achievement of more than 50% reduction of CO leak accidents during 10 years.

This paper discusses definition, concepts, approach methods, application areas, and evaluation of avoided generation costs based on the Korea's official long-term generation expansion plan. The main objective to evaluate avoided costs of resources is to supply decision makers with the breakeven costs of the resources. For the evaluation of avoided costs based on the Korea's generation system, we consider a DSM option which has 1,000MW peak savings, load factor with 70 percents, and life-time with 25 years. The DSM resource can save the fuel spending and capacity additions of a electric utility during its life time. The capacity and fuel savings are evaluated from two different cashflows with and without the DSM option, which are supplied with on the basis of the generation system optimization model (WASP-II), independently. The breakeven kWh costs of the DSM option is projected to be 31.3 [won/kWh], which is composed of generation capacity and fuel avoided costs with 15.0[won/kWh] and 16.3[won/kWh], respectively.
