현대 의학계는 사람의 수명연장의 수단으로 장기이식 연구가 활발하게 진행되고 있다. 그러나 사람의 장기수요가 달리자 다른 동물의 장기이식 실현에 눈을 돌리고 있는데 가장 눈독을 들이고 있는 동물은 돼지라고 한다. 그럼 과연 돼지의 장기를 사람에 이식할 수 있을까?

세상은 변화하고, 모든 생물은 생로병사를 경험한다. 산업과 사업체도 이러한 규칙에서 예외 일 수 없다. 하지만 동식물과는 분명히 다른 측면이 있다. 일반적인 생물은 생로병사의 원 칙을 거역하거나 거스를 수 없지만, 산업과 사업체는 인프라의 혁신과 경영자의 노력에 의해 수명의 단축을 극복하고, 부활의 역사를 쓸 수 있기 때문이다.

In ad-hoc network, the technique to efficiently consume the limited amounts of energy is an important issue since the wireless terminal node is operated on batteries as their energy resource. In order to extend the system lifetime, through a balanced energy consumption, we must delay the situation in which a particular terminal node's energy is depleted and results in system disconnection. Also, the link, which has low reliability due to the mobility of the node, should be avoided considering the key element when setting up the route. The proposed CMLR method in this paper enables to increase the efficiency of energy consumption with a new cost function considering the residue energy of node, error rate of link, and transmission energy consumption. This method is extending the network lifetime and increasing the energy efficiency by compromising the value between the minimization of the transmission energy consumption and maximization of the node's lifetime. Through the simulations the proposed CMLR algorithm was verified by showing better performance over the conventional methods in terms of network lifetime and path efficiency.

The purpose of this study is to analyze the correlation between walking time and lifespan across individuals of various ages and weights to validate the health benefits of walking exercise. The research utilized Python and related libraries to collect and preprocess data, and then analyzed the relationship between walking time and lifespan using Pearson's correlation coefficient. The study was conducted over a period of six months. The analysis results showed a trend towards increased lifespan with longer walking times, which was similarly observed in data using vitamin B2 and folate intake as surrogate variables. These findings suggest that walking exercise may have a positive impact on health and lifespan, and can be used as foundational data for the development of personalized health management services and related policy formulation.
