The purpose of this study was to analyze information about food and nutrition topics presented throughout the television broadcast media, thereby suggest the optimal communication method to give right information to the general public. To perform this study, total sixteen monitoring people were recruited and trained through monitoring practice before and during the study. Five domestic TV channels were selected to be monitored, for six months. For the best efficiency, all the monitoring people were divided into 8 teams based on the regional consideration. The statistical analysis of data was completed using SAS program. The main results of this study are as follows. First, the total reporting cases of information about foods and nutrition were 237, among which about 30% was classified as appropriate and 70% as inappropriate based on the trained monitors' evaluation. Second, the analysis of contents about incorrect informations showed that the insufficient descriptions of terminology and contents were the highest. And insufficient scientific evidences, incorrect contents excessively entertainment-oriented, no provision of alternatives, improper selection of expert advisors were followed. These results suggest that systematical monitoring should be continued to reduce the frequency of incorrect communication thereby give the right information in food and nutrition area to the general public. And there should be a closely cooperated system to provide the professional information to broadcasting production team by establishing the strategic program. In order to do that, most importantly the advisory team should be organized to professionally connect mass media to corresponding specialists. In addition, more educational programs about food and nutrition should be developed provide right information to the general public.

교육인적자원부가 마련한 대학구조개혁 방안은 우리나라 대학교육 현실을 냉정히 성찰하고, 대학의 자율에 기초한 구조개혁을 유도함으로써 대학의 경쟁력 제고를 위한 혁신방안을 수립하였다는데 의의가 있다고 하겠다.

Platycodon grandiflorum have been used as a traditional remedy and food source. This study was performed to investigate the immunomodulating effects of Platycodon grandiflorum in mouse, using ex vivo experiments. Six to seven-week old mice were fed ad libitum on a chow diet, and water extract of Platycodon grandiflorum was orally administrated at two different concentractions (50 and 500 mg/kg B.W./day) every other day for four weeks. In ex vivo experiments, the highest proliferation of splenocytes and levels of cytokine (IL-$1{\beta}$, IL-6, TNF-${\alpha}$) production were observed in 500 mg/kg BW/day supplementation group for all three cytokines stimulated by LPS. In conclusion, this study suggests that Platycodon grandiflorum extracts may enhance the immune function by regulating the splenocytes proliferation and cytokine production capacity by activating macrophages in mice.

Theobroma cacao L., a fruit of cacao trees, is a perennial plant, which belongs to Sterculiaceae, and is native to the Amazon in South Africa. It also has been known for its various biologically active effects, such as anti-oxidation, anti-cancer, and anti-bacterial. The spleen cell proliferations of mice were measured at 48 hours after treatment of Theobroma cacao L. water extracts in seven concentrations(0, 5, 10, 50, 100, 250, 500 and 1,000 μg/mL) an ELISA assay. The production of cytokine (IL-1β, TNF-α, IFN-γ), is secreted by macrophages stimulated with LPS, was detected by ELISA assay using the cytokine kit. From the results of in vitro study, both splenocytes and cytokine production activated by peritoneal macrophages have increased when water extracts were supplemented in the range between 250 and 500 μg/mL concentration. Notably, splenocytes production has a signigicant proliferation at 500 μg/mL concentration. The result from this research suggests that supplementation with Theobroma cacao L. water extracts may enhance the immune function by stimulating the splenocyte proliferation and improving the cytokine production activating macrophage in vitro.

Nelumbo nucifera Gaertn has been usedas a traditional remedy and food source in South Korea. It promotes gastrointestinal function and controls blood pressures. Nelumbo nucifera Gaertn water extracts supplement at 5, 10, 50, 100, 250, 500, $1,000{\mu}g/mL$ after a 48 h pre-treatment with the mitogen (ConA or LPS) increased the mouse splenocytes proliferation. Water extract supplement also increased the cytokine production ($IL-1{\beta}$, $TNF-{\alpha}$ and $IFN-{\gamma}$), measured by a cytokine ELISA kit. For the result of in vitro study, the proliferation of splenocytes and cytokine production activated by peritoneal macrophages increased when water extracts were supplemented in the range of $50{\sim}500{\mu}L/mL$ concentration. Specifically, the levels of the splenocytes proliferation, $IL-1{\beta}$, $TNF-{\alpha}$ and $IFN-{\gamma}$ were the highest at $250{\mu}L/mL$ concentration. This in vitro study suggestedthat supplementation with Nelumbo nucifera Gaertn water extracts may enhance the immune function by regulating the splenocyte proliferation and enhancing the cytokine production activating macrophage in vitro.
