It is not the water veins themselves that are distributed on Earth that are harmful, but the water vein waves generated from the water veins are harmful to human health. The natural frequency of the Earth is 7.83 Hz, but in order to sleep deeply, you must go down to a delta wave of 2 to 3.99 Hz, which is lower than this frequency, to achieve the deepest sleep and maintain your health. However, if you sleep in a place with dowsing waves, the dowsing waves interfere with your brain waves, making it difficult to sleep well, and you may have nightmares. Even when you wake up, your body is not refreshed and your fatigue does not go away, so you feel tired and tired easily. If this phenomenon continues, the body's resistance decreases and immunity weakens, which can eventually cause illness and cause various diseases, which can harm one's health. In other words, the safest and most effective way to deal with water veins is to avoid places with water veins and simply change your sleeping position to a place without water veins, and you can live a healthy and happy life through examples.

The most important characteristic of Emile Bell's sound is a beating. It is modulation phenomenon which appears as a result of interference multiplication in time domain. This modulation phenomenon can be modeled as DSB-SC which suppress carrier and signals distributed both sides. The beatiog wave is observed in Laman distribution signal for polyvinyl speech signal, water vein wave, tide wave. The beating wave is caused by asymmetry Property of the bell.

Because of numerous mountain region, agricultural affairs work can't be done without groundwater in Kangwon Do area. Especially to improve high mountain area vegetable quality and raise income offarmers, both of groundwater and hydrothermal system to keep adequate temperature in hot and coldseason have to be developed. Domestic groundwater was developed for the use of agricultural watersince 1960. Exact investigation and control of groundwater are greatly required in utilizing undergroundspace as subway, nuclear power plant, oil and hazardous waste storehouse. Groundwater contaminationowing to industrial irrigation, trash decomposition can have a serious effect on human health and rustof underground building. In this study, global prospecting system are applied to detect groundwater, using electrical, seismic and georadar prospecting method.
