사회적기업이 많아져야 한다는 사실은 공감하지만 사회적기업의 증가는 기업인의 경영마인드에 달린 것이 현실이다. 얼마 전부터 정부의 지원도 사회적기업을 늘리는 데 한몫을 하고 있으나 근본적으로 사회적 약자의 고용을 촉진하고 사회복지를 위한 기금을 마련하는 데 중요한 사회적기업 자체가 더 늘어나야 한다. 미국의 한 벤처기업가 제프 스콜(Jeff Skoll)은 사회적 기업가를 발굴해 지원하고, 사회적 기업가의 활약을 전 세계에 알리기 위해 '스콜 재단'을 설립해서 주목을 받고 있다. 세계적인 전자상거래 회사 '이베이(ebay)'의 대표였던 스콜은 자신이 거둔 부를 좋은 일에 쓰겠다는 목표로 스콜 재단을 운영하고 있다, 스콜 재단이 펼치는 살기 좋은 세상을 만들기 위한 노력을 알아보자.

The first purpose of this paper is to design brand logo sign analysis frame, 'SCoL'(Analysis frame of signification and communication for the brand logo). It has semiotic view and communication function. And the second is to prove propriety of the suggested frame by application to social media brand logos. The SCoL frame is based on 4 features of logo sigh to have analytic consistency. Also, it covers whole semiological process with index, icon, symbol as signification understanding and reach communication step with Jakobson's theory. As the results, the findings are follow; The SCoL frame can be useful to get comprehensive semiotic understandings and communication functions about logo signs. The social media brands build their own meaning area with logo signs and they depend on different communication function.

This study presented the effects of the assumed mass-size relationship for snow on the simulated surface precipitation by using cloud microphysics parameterizations in Weather Research and Forecasting (WRF) model. The selected cloud microphysics parameterizations are WRF Double-Moment 6-class (WDM6) and WRF Single-Moment 6-class (WSM6) in the WRF model. We replaced the mass-size relationship for snow in WDM6 and WSM6 with Thompson's mass-size relationship retrieved from measurement data. The sensitivity of the modified WDM6 and WSM6 was tested for the idealized 2-dimensional squall line and winter precipitation system over the Korean peninsula, respectively. The modified WDM6 and WSM6 resulted in the increase of graupel/rain mixing ratios and the decrease of snow mixing ratio in the low atmosphere. The changes of hydrometeor mixing ratio and surface precipitation could be due to the collision-coalescence process between raindrops and snow and the graupel melting process.

The intensive observation (ProbeX-2010) with 6-hour launches of radiosonde was performed over Seoul metropolitan area (Dongducheon, Incheon Airport, and Yangpyeong) from 13 Aug. to 3 Sep. 2010. Five typical heavy rainfall patterns occurred consecutively which are squall line, stationary front, remote tropical cyclone (TC), tropical depression, and typhoon patterns. On 15 Aug. 03 KST, when squall line developed over Seoul metropolitan area, dry mid-level air was drawn over warm and moist low-level air, inducing strong convective instability. From 23 to 26 Aug and from 27 to 29 Aug. Rainfall event occurred influenced by stationary front and remote TC, respectively. During the stationary frontal rainy period, thermal instability was dominant in the beginning stage, but dynamic instability became strong in the latter stage. Especially, heavy rainfall occurred on 25 Aug. when southerly low level jet formed over the Yellow Sea. During the rainy period by the remote TC, thermal and dynamic instability sustained together. Especially, heavy rainfall event occurred on 29 Aug. when the tropical air with high equivalent potential temperature (>345 K) occupied the deep low-middle level. On 27 Aug. and 2 Sep. tropical depression and typhoon Kompasu affected Seoul metropolitan area, respectively. During these events, dynamic instability was very strong.
