The purpose of this study is to find out about unknown golf activities through sociological analysis based on the relationship between King Youngchin's life in Japan and the people around him. The following conclusions were drawn. King Youngchin was influenced by the Japanese imperial family to learn golf for the first time in 1924, and participated in golf tournaments in 1925. In 1927, during a one-year European tour, he participated in golf games in Singapore, Paris, Switzerland, England, Belgium, the Netherlands, and Italy, as well as golf course tours, golf lessons, and visiting golf ball manufacturing factories. After returning from Europe, he provided support for the site of Gyeongseong Gunjari Golf Course, construction and operation expenses. However, he did not show any special golf activities during his life as a high class Japanese military officer, and after the Pacific War, he could not find any more golf activities due to social conditions and economic conditions such as wartime restoration. There were no more golf activities due to health problems from 1958.

Soil samples from the King Sejong Station in Antarctic and Vladivostok were tested in the laboratory and specific gravity, compaction curve, grain size distribution were determined. The effect of temperature change on the thermal conductivity, unfrozen water content, compressive strength were investigated. In addition, the change of tensile strength with temperature of the soil from Vladivostok was measured. Samples for the compressive strength test and tensional strength test were prepared in a mould with a fixed volume to prevent swelling. Also the effects of temperature and water content change on those strength were compared. Results from the thermal conductivity test showed that thermal conductivity values for both soils was larger at temperatures below freezing than those above freezing. The unfrozen water content dropped rapidly within a temperature range of $0{\sim}-5^{\circ}C$ and then gradually decreased further $-20^{\circ}C$. Compressive strength test results showed various stress/deformation curves with a change in water content. Sandy soil of the King Sejong Station had a much larger strength than ice at an identical temperature, while clayey soil of Vladivostok had a smaller strength than ice in the initial stage, but showed a larger strength at temperatures belows $-15^{\circ}C$. Tensile strength tests revealed an increase in the strength with a decreasing temperature.
