주거, 상업, 공공시설용지 등의 토지개발은 시외지역에 비하여 도심지역의 온도가 상승하는 원인이 되어왔다. 따라서 본 연구에서는 강변지역과 해안지역을 중심으로 연구지역을 선정하여 토지이용 및 기후변화에 따른 온도변화를 분석하였고, 또한 지형적 특징과 온도변화와의 상관관계를 알아보았다. 2003년에 비해 2007년 기온은 1.80℃ 증가하였고, 풍속은 0.24m/s 감소하였다. 또한 시가화 지역은 3.27% 증가하였고, 산림지역은 2.54% 감소하였다. 상관관계를 비교 분석한 결과 강변지역은 초지와 나지가, 해안지역은 산림과 초지에서 지형인자와 기후인자간의 상관성이 비교적 높게 나타났다. 이러한 연구결과는 지역 특성에 따라 열섬현상 문제에 대한 방안을 제시, 예측 등의 기초자료로 활용될 것으로 기대된다. Development of housing, industrial and public lands has been a cause to increase a temperature of a city higher than that of a rural area. Knowing that, the research analyzed temperature changes in a riverside district and a coastal area depending on the land usage and climate change in the areas. Add to this, the study examined a correlation between topographic characteristics and temperature changes. According to the results, the temperature was increased by 1.80℃ in 2007 comparing to 2003 while the wind velocity was reduced by 0.24m/s. In addition, a more number of areas were designated as build-up areas which, in return, decreased the forested land. The analysis on the correlation reported that the riverside district has more of grassland and bare land while the coastal area has more of wooded land and grassland. The study is expected to be used as fundamental data for research on heat island effect which would be different by each regional characteristic as it proposes measures to solve the heat island effect.

By employing transaction cost theory and bargaining power model this study analyzed the determinants of the increase in equity of Korean overseas joint ventures. According to the results of this study, Korean firms with majority equity at the time of entry into foreign markets had a greater tendency to increase in their equities later. In addition, Korean firms with more technological know-how and international experience had a greater tendency to increase their equities. However, host conutry government regulation did not affect the increase in equity of joint ventures.
