tungsten-made shaft with suitable sizes. Considering all market situations, most golf equipment manufacturers have been trying to co-develop various size lines of proprietary shafts with companies specializing in shaft design and manufacturing.
2. Changes in Distribution Channels
At past, there was only one channel to purchase golf equipments; off-course shops. After activating e-commerce,
3. Expanding Investment on Endorsement with Tour Professionals

1. 실험 목적
온도 측정 실험에서는 고체면의 열전달률(heat transfer rate)를 촉진시키기 위해 사용되는 방법 중의 하나인 fin을 사용한 열전달량을 살펴봄으로써 열전달 이론에 대한 실제적인 이해와 적용을 할 수 있도록 한다. 이를 위해 구리 fin과 온도에 따라 색상이 변하는 액정(TLC : Thermo
