The purpose of this study is to investigate the aspects of school life satisfaction and academic stress for adolescents participating in school sports clubs in G metropolitan city. A questionnaire and α-amylase measurement were simultaneously conducted by dividing male and female students. To verify the difference between the two groups (male and female), the following conclusions were drawn based on the results of independent t-test and frequency analysis. First, as a result of the satisfaction of school life of students participating in school sports club activities, the items that are commonly high among boys and girls are 20, 2, 24, and 12. They had pride in school, a teacher who was intimate, and friends with whom they were not close in the same class, and it was uncomfortable to be in school. Second, there was no statistically significant difference between the two groups in the academic stress of students participating in school sports club activities, but the result was not high in α-amylase, an academic stress item. In summary, the results of a study to find out the direction of future guidance through the results of the school life satisfaction of the youth participating in school sports clubs were shown, and the results showed that academic stress was reduced through sports club activities. In addition, it is thought that it can be lowered through active and active participation, recognizing that female students generally have higher academic stress than male students.

Objectives : NK cells are spontaneously cytotoxic lymphocytes. These are not only important parts in the first line of defence against bacterial and viral infections of outside, but they may also play a critical role in chronic viral diseases. NK cells kill their targets spontaneously, without the need for prior sensitization and class I MHC restriction by the regulation of cytolytic functions and secretion of a variety of cytokines, such as interleukin-12(IL-12), MCP-1, IL-6, TNF-${\alpha}$, IFN-${\gamma}$. In addition, macrophage and NK cells cooperate through the production of cell mediates. These cooperation and modulation are one of major factors to prevent for evading immune surveillance of cancer. Hence, it could be assumed that if any candidate to enhance activities of macrophage and NK cell, it is considered as a potentially useful agents against cancer. Methods : In our study, to investigate effect of fermented soybean extracts by Lactic acid bacteria (SFE, soybean fermented extracts) work on intestinal immune cell to maintain general immune modulating and anti-cancer activity. We analyzed NK cytotoxicity assay and gene expressions of cytokine related with macrophage and NK cell activity. Results : In vitro experiment, SFE was verified as safety material for cell toxicicty to tumor cell strain without any toxicity of tumor growth inhibition and various cell strain. Effects of macrophage activity stimulating directly by SFE measured induced cytokine. The studies showed that IL-12 production by stimulation of SFE depended on concentration from 0.16mg/mL to 0.63mg/mL with non toxicity to cell, and it was the best activity at 0.63mg/mL. Besides, the effective concentration of SFE producing TNF-${\alpha}$ is similar to IL-12, but it was the best activity at 1.25mg/mL. The level of MCP-1, IL-6 and IFN-${\gamma}$ depended on concentration from 0.16mg/mL to 10mg/mL, IFN-${\gamma}$ showed the best activity at the effective concentration of 0.63mg/mL. With the result of NK cell activity measurement, the spleen cell of mouse injected SFE had 1.5 times higher killing effect than non injected cell. Conclusions : The result of this studies is that Soybean fermetated extracts(SFE) has possibility to immune aided material for the function not only inhibition of microbial infection to macrophage but also activity of adaption immune and cellular immune system.
