Electrical energy storage (EES) systems store generated electricity in energy storage devices such as batteries and discharge the stored energy when necessary. Individual subsystems of the EES system are being standardized independently; however, a holistic understanding of the whole system is necessary because the EES system is large and complex. IEC TC 120 has developed international standards of EES systems. In this paper, EES systems standards in IEC TC 120, including the planning and installation of EES systems, are presented. Further, ongoing standardization for the application of EES systems to backup power and emergency support is described.

This paper's aim is to research especially the being types, historic background of form of this type legends, and jugglery of the original domicile of Juwonjang, who is the proprietor of this story. In accordance with the contents of epic process, I divided the Juwonjang legend into four types as follows, specially closely linked with 1)the rebirth of animal as man, 2)the making love with other animal, 3)the theory of configuration of the ground type, 4)the Lee, Sung-Kae who is the founder of the Choseon Dynasty. Also in this paper, I researched that the legend of 'Juwonjang''s historic backing was regarded with the change of China dynasty, It s that Won(元) changed into Myung(明). Juwonjang is the founder of the Myung Dynasty in China And korye(高麗) dynasty people believed and appreciated that Juwonjang set free them from Won dynasty's plunder. On account of this historic background, 'Juwonjang' legend was formed and transmitted year after year in Korea. In addition to, Korye people believed Juwonjang s original domicile was Choseon. Because they were proud of superiority than Chinese and wanted to criticize indirectly the korean ruling class who had a sense of inferiority to Chinese.
FIDOL 개념을 이용한 산단 주변 악취 영향에 관한 연구

This study investigated impact of odors from industrial areas using the FIDOL concept. The studied region was the Seobu industrial complex in Korea. The USEPA dispersion model, AERMOD, was used to calculate odor concentration. The results show that the size of the impact areas of lower regulation compliance frequency is smaller than that of the areas of higher regulation compliance frequency. The results also showed that increasing the concentration of odor unit (OU) decreased the size of the impact area and the maximum impact distance. Calculated odor impact area, using Massachusetts (USA) regulations, had the smallest impact area among selected locations such as Massachusetts (USA), New Zealand, Denmark, and the Netherlands. Denmark’s regulations had the largest impact area.
다중 방음벽 주변의 대기 오염물 이동에 관한 연구(II)-이중오염원

Noise barriers along the road do not only block the traffic noise but also prevent traversing the car exhausts. These barriers may affect air pollution dispersion, leading to increase vertical mixing due to the upwind deflection of air flow caused by the noise barriers. In this study we investigated the air pollution dispersion around multi-noise barriers using commercial software FLUENT. Investigated cases were 8 cases which had from zero to three noise barriers and two emission sources. Simulated results show noise barriers increase the vertical air pollution impact distance larger 1.7~2.1 times than that of no barrier case. It was also found that noise barriers decrease the horizontal air pollution impact distance lower 0.6~0.8 times than that of no barrier case.
CFD 모델을 이용한 단일 방풍벽 및 방풍언덕 주변 대기오염물 이동에 관한 연구

To investigate the effect of single windbreak and combination of hill and windbreak on pollutant dispersion in neutral boundary condition, CFD (Computational Fluid Dynamics) modeling was used. The validity of the CFD model was confirmed by wind tunnel and field experiments of single closed windbreak. The results show increased windbreak height increasing the height of maximum concentration position and decreasing surface concentration (x=50 m) from 1.5 to 5.0 times smaller than that of non-windbreak case. In combination of hill and windbreak case increasing hill height decreasing surface concentration from 1.0 to 1.1 times smaller than that of single windbreak case.

Because many recent epidemiological studies have reported the associations of population’s proximity to high traffic roadways with adverse health effects, interest in how roadside structures affect the concentration of motor vehicle emitted pollutants in the near-road microenvironment has increased. These noise barriers may affect pollutant (for example: odor, carbon dioxide, particle et al.) concentrations around structure by blocking initial dispersion. This study examined the effects of roadside barriers on the flow patterns and dispersion of pollutants from high traffic highway. The effects of noise barriers were examined using commercial software FLUENT. The results show noise barriers increase concentration of near noise barrier wake region and decrease concentration in the faraway distance from noise barrier. The results also show far from emission position (between 100 m and 200 m) surface concentration of multi-barrier cases are 2 times lower than that of no barrier case.
