  • 유무선 통합 환경에서의 기존의 TCP가 가지는 문제점은 혼잡 제어 알고리즘이 무선환경의 에러를 모두 congestion으로 인식하는 것에 있다. 무선환경에 의한 에러일 경우 네트워크의 상황이 좋음에도 불구하고 전송률을 낮춰서 네트워크의 성능을 떨어뜨리게 된다. 따라서 본 논문에서는 Link-layer가 발생시킨 이벤트를 통해 에러의 원인을 명확이 구분하여 기존의 TCP의 큰 수정이 없이도 성능을 크게 향상 시킬 수 있는 혼잡 제어 알고리즘을 제안한다.

  • In this study, the changes in occlusal strength and oral environment before and after the use of natural gargles containing cinnamon were confirmed. This study involved 42 adults aged 19 or older living in Busan from November 25 to December 2, 2023. Twenty-one people were randomly selected for each of the regular and natural gargles. In this study, the group using natural gargles confirmed an increase in saliva buffering power, a decrease in O'Leary index, and an increase in occlusal strength. Through this, it was confirmed that natural gargles containing cinnamon are helpful in improving the oral environment and occlusal strength.

  • To investigate the effect of fluoxetine, one of selective serotonin reuptake inhibitors (SSRIs), on the immune system, human peripheral blood mononuclear cells (PBMC) were treated with fluoxetine $(10^{-7}\;M)$ for 24 h, and immune-related genes were analyzed by cDNA microarray. Expression of the immunerelated genes such as CD107b (LAMP-2), CD47 receptor (thrombospondin receptor), CD5 antigen-like (scavenger receptor cysteine rich family), copine III (CPNE3), interleukin (IL)-18 (interferon-gammainducing factor), integrin alpha 4 (CD49d), integrin alpha L subunit (CD11a), IL-3 receptor alpha subunit, L apoferritin, and small inducible cytokine subfamily A (Cys-Cys) member 13 (SCYA13) was induced by fluoxetine. This result suggests that fluoxetine may affect the immune system, and provides fundamental data for the involvement of SSRIs on immunoregulation.
