  • 보리를 초기의 고수분 상태에서 연속적이고 효과적인 인공건조를 실시하기 위하여 보리의 물리적 특성을 구하였으며, 또 유동층 건조장치를 제작하여 유동화 특성을 실험하여 이론식과 비교 검토하였다. 공기의 온도 및 상대습도가 각각 $35^{\circ}C$, 30%이고 충전량이 300g일 때 쌀보리와 겉보리의 최소 유동화 속도는 1.5m/s 및 1.7m/s였으며, 최적 유동화 속도는 3.0m/s였다. 본 실험에서 실험한 쌀보리와 겉보리의 $U_{mf}$는 1.5m/s 및 1.7m/s였으며, Leva식에 의한 계산치는 각각 1.06m/s 및 1.07m/s로 실험치와 계산치는 잘 일치하지 않았다. 또한 쌀보리와 겉보리의 유동층 건조에서 실험치와 일치하는 다음과 같은 최소 유동화 속도에 관한 실험식을 얻었다. $U_{mf}^2= \frac{{\phi_s}\;d_p}{Hk}\;{\cdot}\;\frac{(\rho_s-\rho_g)g\;{{\varepsilon}_{mf}^3}} {\rho_g}(Re_p>1,000)$ 이 실험의 상수 Hk는 쌀보리 및 겉보리가 각각 0.4881, 0.6649였다.

  • Purpose: Isoform 2 of tight junction protein claudin-18 (CLDN18.2) is a potential target for gastric cancer treatment. A treatment targeting CLDN18.2 has shown promising results in gastric cancer. We investigated the clinical significance of CLDN18.2 and other cell-adherens junction molecules (Rho GTPase-activating protein [RhoGAP] and E-cadherin) in metastatic diffuse-type gastric cancer (mDGC). Materials and Methods: We evaluated CLDN18.2, RhoGAP, and E-cadherin expression using two-plex immunofluorescence and quantitative data analysis of H-scores of 77 consecutive mDGC patients who received first-line platinum-based chemotherapy between March 2015 and February 2017. Results: CLDN18.2 and E-cadherin expression was significantly lower in patients with peritoneal metastasis (PM) than those without PM at the time of diagnosis (P=0.010 and 0.013, respectively), whereas it was significantly higher in patients who never developed PM from diagnosis to death than in those who did (P=0.001 and 0.003, respectively). Meanwhile, CLDN18.2 and E-cadherin expression levels were significantly higher in patients with bone metastasis than in those without bone metastasis (P=0.010 and 0.001, respectively). Moreover, we identified a positive correlation between the expression of CLDN18.2 and E-cadherin (P<0.001), RhoGAP and CLDN18.2 (P=0.004), and RhoGAP and E-cadherin (P=0.001). Conversely, CLDN18.2, RhoGAP, and E-cadherin expression was not associated with chemotherapy response and survival. Conclusions: CLDN18.2 expression was reduced in patients with PM but significantly intact in those with bone metastasis. Furthermore, CLDN18.2 expression was positively correlated with other adherens junction molecules, which is clinically associated with mDGC and PM pathogenesis.

  • Let f(z) be an entire function. Then the order $\rho(f)$ of f is defined by $$ \rho(f) = \overline{lim}_r\to\infty \frac{log r}{log^+ T(r,f)} = \overline{lim}_r\to\infty \frac{log r}{log^+ log^+ M(r,f)}, $$ where T(r,f) is the Nevanlinna characteristic of f (see [4]), $M(r,f) = max_{$\mid$z$\mid$=r} $\mid$f(z)$\mid$$ and $log^+ t = max(log t, 0)$.

  • In this paper, we formulate a sufficient optimality theorem for the robust optimization problem (UP) under (V, ${\rho}$)-invexity assumption. Moreover, we formulate a Mond-Weir type dual problem for the robust optimization problem (UP) and show that the weak and strong duality hold between the primal problems and the dual problems.

  • We show that if dialation operator $\parallel\sigma_r\parallel\; E=\Psi(r)$ of E, then $\Lambda_\subset_{\Psi1}E\subset\;M_\Psi$, We also show that there are lattice-isomorphic copies of $l_\rho \; and \;l_\infty$ in $M \Psi$ under some condition.

  • The photoinducible DNA cleaving activities of bromofluoroacetophenones as a novel photonuclease were investigated. The photolytic behavior and DNA cleaving acitivity of fluorine derivative were compared with those of non-fluorine substituted compound, 4'-bromoacetophenones. Although the DNA cleaving activities of fluorine analogs were similar with those of 4'-bromoacetophenones, ο-bromo-$\rho$-fluoro derivatives gave the better DNA cleaving activities than $\rho$-bromo-ο-fluoro derivatives did.
