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.

Abstract
PURPOSE
Our main goal is to test the reliability and validity of the Korean version of Baecke questionnaire on physical activity by using 507 men and women aged 20-70 years.
METHOD
This study was carried out using the cancer screening participants of the National Cancer Center. All subjects were sent the Korean version of Baecke questionnaire by mail to measure their physical activity.
RESULTS
The mean score on the sport index during leisure-time for men was significantly higher than that for women. In contrast, the mean score of the work index for men was significantly lower than that for women. Cronbach`s alphas for work, sport and leisure-time index were 0.75, 0.81 and 0.39 for men, respectively, and 0.67, 0.75 and 0.35 for women respectively. By a principal components analysis the three conceptually meaningful factors were distinguished, except for the leisure-time factor. Due to the low cronbach`s alphas and undistinguished factors, work and sports factors were used on the final analysis, excluding the leisure time factor, in the Korean version of Baecke`s questionnaire. Two-factor analysis was used to assess the validity of work items and sports items. Work factor and sports factor were definitely distinguished as two factors. Multiple regression analysis showed that lean body mass was significantly related the work index(p<0.0001) and sports index (p<0.05).
CONCLUSION
Our results suggest that the modified Korean version of Baecke`s questionnaire is appropriate to assess the physical activity in Koreans.

Abstract
In order to examine the past infection rate an incidence of Scrub typhus a seroepidemiologi study was performed in Koje County. Paired serums were collected from 518 residents in Sadeung and Koje myun. Serum were analyzed by ELISA for detection o IgG to R. tsutsugamushi, and were also analyzed by Microscopic Agglutination test for Leptospirosis. First serum were collected from Aug. 25 to Aug. 31, 1987 and second serum were collected from Jan. 13 to Jan 31, 1988. The result summarized as follows: 1. One hunderd seventy people(33.9%) had a experience of infection by R. tsutsugamushi: among 501 subjects. The past infection rate was significantly higher in female than that in male and it was increased according to age. By occupation farmers showed the highest infection rate. 2. The incidence rate of Scrub typhus was estimated 4.7%(19 people among 405 subjects) during the study period. The incidence rate was also significantly higher in female than that in male and 40-49 age group showed the highest incidence rate. 3. Two people(0.4%) were reacted to Microscopic Agglutnation test for Leptospirosis. Among 501 sujects and these two people were also reacted to ELISA for Scrub typhus.

Abstract
In order to sum up the cumulative quantity and ratio of practice delivered during the 24th Seoul Olympic Games to the participating athletes and officials, descriptive study was derived from the Olympic Health Management Information System(OHMIS) in the SLOOC. There were analyzed with the quantity of disease incidence and physician visit dividing by the total participating person. 1. The average physician visit per the participating athletes in Seoul amounted 0.49 was smaller than 0.75 at L.A. and 0.53 at Montreal, however, if A.T. service is considered the ratio, was about the same level with that of L.A. 2. Venue medical services utilization was much larger with amounted 72.4%, whereas village medical center’s utilization was smaller with 26.9%. The number of out-patient physician visit per hundred persons during 2 weeks period in venue clinic was 22.4 times and village medical center was 8.33 times and athletes, officials and others’ medical demand excluding spectators was 30.9 times. 3. The quantity of medical demand increased as the number of athletes and officials increased, however, the increase of utilization rate was not so significant. 4. The medical demand was calculated by continents respectively, and Africa, central and south America, middle east Asia proved to higher rate than more industrialized continent or region. 5. The Medical demand according to sports, event can be ranked from higher to lower in such order as arranged as follows: Yachting, Wrestling Tennis, and Soccor, etc. The medical demand according to international classification of disease-9, accident and injury ranked highest.
