The purpose of this study was to examine the association perceived physical activity pattern and body mass index according to habitual internet usage among middle school student. Data were analyzed for 969 students who responded to self-reported base cross-sectional survey relating to socio-demographic variables, internet usage status, and a short version of the international physical activity questionnaire. Prevalence rate of physical activity status showed that 53.5% at 150 min/week under, 46.5% at 150min/week over. Prevalence rate of internet usage showed that 95.6% at normal group, 2.6% at potential group, 1.9% at addiction group. Prevalence rate of body mass index status of over weight according to internet usage status showed that 83.1% at normal, 5.1% at potential, 11.9% at addiction. Prevalence rate of physical activity levels of 150 min/week under according to internet usage status showed that 93.8% at normal, 3.5% at potential, 2.7% at addiction. In comparison with the physical activity levels was significantly more likely potential internet usage (OR, 2.62; 95% confidence interval [95%CI], 1.09-6.47; p<.05) and addiction usage (OR, 3.82; 95% confidence interval [95%CI], 1.24-11.75; p<.05). The results revealed that physical activity levels and body mass index correlates of internet usage status. This finding suggest the necessity of developing specific strategies for physical activity intervention by internet addiction among middle school students.

Primary papillary serous carcinoma of the peritoneum(PPSCP) is vere rare. It has been suggested that PPSCP derives from embryonal coelomic epithelium with m llerian ducts potential. PPSCP can develop from a single or multicentric focus. The clinical and histologic disease entities are similar to those of primary papillary serous carcinoma of the ovary, but PPSCP involves the ovarian surface only minimally(microscopic disease) or spares the ovaries entirely. We have experienced a case of primary papillary serous carcinoma of the peritoneum and report this case with brief review of the concerned literature.
