Abstract: 리더는 많은 사람들의 말을 잘 들어야 한다. 그러나 수 많은 사람들의 말 중에 옥석을 가려서 실행해야 한다. 
바둑은 인생과 같은 원리가 숨어 있다. 수 많은 수가 있고 이러한 수 중에서 가장 합리적인 수를 선택하는 것이다. 이래도 한판 저래도 한판이지만 일관성을 유지하고 승부처에서는 과감한 결단이 중요하다. 다만 인생과 바둑의 차이는 바둑에서는 반집만 적으면 패하는 것이지만 인생의 바둑은 집이 만들어지거나 상대방 돌을 조금 잡으면 상대방보다 적은 집을 차지하더라도 생존할 수 있다. 나름 멋진 인생을 살 수도 있는 것이다. 인생에서는 승패에 연연할 필요없이 최선을 다해서 즐겁게 사는 것이 현명한 삶이다. 
경쟁에서 이기기 위해 발버둥 치는 것보다 자신에게 정직한 삶을 살아가면서 얻는 작은 보상이 더 소중하고 더 가치가 있다. 그 보상들이 모여 여러분들의 행복을 극대화시켜줄 것이다. 가치중립주의는 스스로 지키고 서로 지켜준다. 기본 일하고 기본 보상을 받는다를 목표로 한다. 바로 개인의 행복을 극대화시켜주는 조건인 것이다. 물론 추가 일하고 추가 보상을 받는 것도 당연하다. 여기서 주의할 것은 기본 일하는 것에 있어서 대충 일하는 것이 아니라는 것이다. 기본은 당신을 고용한 사람에게 당신이 정직하게 보상을 요구할 수 있는 마음을 가질 수 있는 마음가짐을 충족시킬 수 있어야 한다. 당신의 기본 일에 보상을 해주는 이들이 사회의 평균자본수익률 또는 업계의 평균자본수익률 이상을 얻을 수 있도록 노력해주어야 한다. 그러면 여러분도 안정적인 일을 계속해서 얻을 수 있고 추가적인 일에 대해 추가적인 보상도 얻을 수 있을 것이다. 
개인의 행복의 극대화를 위해서는 여러분들의 일하는 마음가짐이 중요한 것이다. 또한 여러분에게 일자리를 제공한 사람 역시 여러분들의 고마움을 아는 마음가짐이 중요한 것이다.

Abstract: A cooling device for autonomous cooling of a rack hosting components and fans includes a closed loop and an open loop. Liquid cooling is used in the closed loop to transfer heat from heat-generating units of the components to a primary side of a liquid-to-liquid heat exchanger. An air-to-liquid cooling unit is used in the open loop to absorb heat expelled from the rack by the fans. A liquid from a cold supply line is first heated to some degree in the air-to-liquid cooling unit before reaching a secondary side of the liquid-to-liquid heat exchanger. The primary side is hotter than the secondary side, and heat is transferred from the primary side to the secondary side of the liquid-to-liquid heat exchanger. The liquid is expelled at a higher temperature from the secondary side to a hot return line.
