This study aimed to investigate the trend of the articles regarding the golf industry in South Korea, which had been published in journals for the recent five years, and determine if the research as to the golf industry was conducted in a balanced way for the purpose of academic improvement. Of 884 articles obtained with the key word, 'golf,' among those published in a total of 11 academic journals―the Korea Journal of Sport, which were related to sports in South Korea for the recent five years from 2014 to the first half of 2019, 158 articles regarding the golf industry were chosen for the purpose of this study. First, 42 articles were related to each of golf items and screen golf (53%), 35 (22.2%) were related to golf service, 23 (14.5%) were related to the methods of managing golf courses, and 16 (10.1%) were related to golf facilities. Second, the 158 articles regarding the golf industry published in the South Korean sport-related journals from 2014 to the first half of 2019 generally showed a similar trend and it was the area investigated on a steady basis, regardless of year. Third, as for the classification by data processing, quantitative research formed the largest part: 130 articles (82.3%). Besides, there were 21 articles (13.3%) of qualitative research and 7 articles (4.4%) of literature review; number-using research was actively and absolutely under way among the articles regarding the golf industry in the South Korean sport-related journals. It is therefore necessary to perform qualitative research and literature review more actively in pursuit of diversity and more detailed research.

There are many problems in application of waterproofing such as quality insurance of over-lap of waterproofing sheets and delay of construction term because of hardening time of paste type being taken long time to get dried, comparing spray type with paste type in waterproofing membrane coating, and increase of man power because of forming layer of waterproofing by pasting. Therefore, the management of construction quality is suggested in this study by means of estimation its tensile performance and temperature dependency according to injection distance, angle and mix proportion. The management referenced of quality for construction is as follows according to the result of testing. The spray angle referenced : 45° The distance referenced from concrete surface to injection gun : 50㎝ The mix proportion ratio of principal agent and hardener is 4 : 1. The usage of reinforcing fabric : consider direction of elasticity, width, penetration degree.

This study deals with the estimation of material properties according to the construction condition for water-soluble rubberized asphalt waterproofing material of spray type. In this study, the waterproofing material property by the spray construction method is suggested by means of estimation its tensile performance and temperature dependency according to mix proportion ratio(4:1, 8:1), referenced viscosity and solid content (A:360cps, 76%, B:580cps, 79%, C:490cps, 70%), spray angle($30^{\circ}$, $45^{\circ}$, $60^{\circ}$), and spray distance(30cm, 50cm, 70cm). The result of testing are as follows. (1) The mix proportion ratio of principal agent and hardener is 4:1. (2) The viscosity referenced and solid content are 490cps and 70%. (3) The spray angle referenced is $45.^{\circ}$ (4) The distance referenced from concrete surface to spray gun is 40~50cm.
