게임 봇은 게임에서 사용되는 재화 또는 아이템 등을 대량으로 유통시키며 게임 재화 및 아이템의 가치를 하락시키는 한편 아이템을 획득하기 위해 봇끼리 몰려다니면서 몬스터를 사냥하고 아이템을 채집하므로 일반 유저들이 정상적으로 콘텐츠를 즐기는 활동을 방해해 왔다. 그러나 봇의 증가가 구체적으로 어떤 유형의 유저에게 영향을 미치는지, 그리고 어떤 활동 유형을 감소시키는지에 대한 연구는 알려진 바가 없었다. 이에 따라 본 연구에서는 게임 유저들의 접속 데이터를 토대로 유형을 분류하고 봇의 증가에 따른 유저 이탈과의 상관관계를 분석함으로써 유저들의 게임 이용을 유도하는 실무적인 시사점을 제공한다.

Actual evapotranspiration (AET) in the Suyeong-gu was estimated and correlations between AET and meteorological factors were analyzed. The study area was Suyeong-gu lay at the east longitude 129° 05′40″∼ 129° 08′08″ and north latitude 35° 07′59″∼ 35° 11′01″. The Kumryun mountain, the Bae mountain, the Suyeong river and the Suyeong bay are located on west, north, northeaster and south side in the study area, respectively. AET was estimated using precipitation (P), potential evapotranspiration (PET) and plant-available water coefficient. Meteorological factors to estimate PET were air temperature, dewpoint temperature, atmospheric pressure, duration of sunshine and mean wind speed (MWS). PET and AET were estimated by a method of Allen et al. (1998) and Zhang et al. (2001), respectively. PET was the highest value (564.45 mm/yr) in 2002 year, while it was the lowest value (449.95 mm/yr) in 2003 year. AET was estimated highest value (554.14 mm/yr) in 2002 year and lowest value (427.91 mm/yr) in 2003 year. Variations of PET and AET were similar. The linear regression function of AET as PET using monthly data was and coefficient of determination was high, 0.75. In order to analyze relationship between the evapotranspiration and meteorological factors, correlation analysis using monthly data were accomplished. Correlation coefficient of AET-PET was 0.96 high, but they of AET-P and PET-P were very low. Correlation coefficients of AET-MWS and PET-MWS were 0.67 and 0.73, respectively. Thus, correlation between evapotranspiration and MWS was the highest among meteorological factors in Suyong-gu. This means that meteorological factor to powerfully effect for the variation of evapotranspiration was MWS. The linear regression function of AET as MWS was and coefficient of determination was 0.54. The linear regression function of PET as MWS was and coefficient of determination was 0.45.
