Abstract
OBJECTIVES
To investigate the differences in accessing regional hospitals and the utilization rate of hospitals located in other regions for cancer patients by regions.
METHODS
Data for the utilization of regional hospitals for cancer patients were obtained from the Korean National Cancer Incidence Databases in 1999 and 2002. We divided the regions into 16 provinces by administrative districts. We using the SAS 9.1.3 to analyze difference of regional self-sufficiency and the Arcview 3.2 to show in a schematize for regional variation of the regional self-sufficiency.
RESULTS
There were regional variations in the regional self-sufficiency of cancer patients. Especially, Jeollanam-do(1999 13.6%, 2002 12.8%), Gyeongsangbuk-do(1999 22.0%, 2002 20.7%), and Chungcheongnam-do(1999 27.8%, 2002 27.1%) had low regional self-sufficiency. The regional self-sufficiency in Gyeonggi-do and utilization rate of cancer patients who lived in other regions were increased between 1999 and 2002(regional self-sufficiency: 1999 37.2%, 2002 48.2%).
CONCLUSION
The results of this study showed that there were regional variation in utilization of regional hospitals for cancer patients. Accessibility of cancer patients in metropolitan areas was higher than in small size cities, medium size cities, and rural county areas. These results suggested that it should be considered support medical facilities for cancer patients in rural areas where have lower relevance rate.

Abstract
OBJECTIVES
To investigate the relationship of internet addiction and depression, and evaluate other possible related factors.
METHODS
Data was based on the questionnaires from 300 college students in Seoul. Gender, age, major, family income, academic performance, people they live with, location, and main use of internet were included. We used Young`s Internet Addiction Test and Beck Depression Inventory(BDI) to measure the depression and addiction degree.
RESULTS
In logistic regression analysis, it was found that gender, depression degree and main use of internet were significant variables. There were 136 males, 144 females in this study, and the risk of being addicted to internet were 10.9 times(CI:2.67~44.68) higher in male than female. People with moderate depression (Beck`s Depression Inventory(BDI) Score>20) also had higher risk(11.4 times, CI:2.03~63.95) to be addicted in internet than normal group. Lastly, in case of internet use, people who use internet for games and chatting were 6.38(CI:1.38~29.63) and 4.84 times(CI:1.30~18.06) risky compare to the group with web surfing.
CONCLUSION
The result of this study suggests that there is noticeable relationship of internet addiction and depression. However we do not have evidence of exact relation between them, therefore more studies should be done.
