  • A method of restoring the occluded area was proposed by referring to images taken with the same types of sensors on high-resolution optical satellite images through deep learning. For the natural continuity of the simulated image with the occlusion region and the surrounding image while maintaining the pixel distribution of the original image as much as possible in the patch segmentation image, CycleGAN (Cycle Generative Adversarial Network) method with ConvNeXt block applied was used to analyze three experimental regions. In addition, We compared the experimental results of a training patch size of 512*512 pixels and a 1024*1024 pixel size that was doubled. As a result of experimenting with three regions with different characteristics,the ConvNeXt CycleGAN methodology showed an improved R2 value compared to the existing CycleGAN-applied image and histogram matching image. For the experiment by patch size used for training, an R2 value of about 0.98 was generated for a patch of 1024*1024 pixels. Furthermore, As a result of comparing the pixel distribution for each image band, the simulation result trained with a large patch size showed a more similar histogram distribution to the original image. Therefore, by using ConvNeXt CycleGAN, which is more advanced than the image applied with the existing CycleGAN method and the histogram-matching image, it is possible to derive simulation results similar to the original image and perform a successful simulation.

  • Objective : This study aimed to investigate the effects Samyoo-tang Extract (SE) on the vascular systems, including changes in blood pressure and regional cerebral blood flow (rCBF), of male Sprague-Dawley rats. Methods : The changes in rCBF were determined by Laser-Doppler flowmetry through the opened cranial method and norepinephrine (NE)-induced blood vessel contractions were determined by physiograph in the pulmonary artery of isolated rabbits. Results and Conclusion : 1. Contractions evoked by NE ($ED_{50}$) were inhibited significantly by SE in the pulmonary artery. 2. SE inhibited the relaxation of NE induced contractions pretreated with propranolol. 3. SE did not inhibit the relaxation of NE induced contractions pretreated with ODQ and L-NNA. 4. Blood pressure was not affected by SE in rats. 5. rCBF was increased by SE in a dose-dependent manner. 6. Pretreatment with propranolol was increased by SE in a dose-dependent manner in blond pressure. 7. Pretreatment with methylene blue, ODQ and L-NNA did not inhibit SE induced increased in rCBF. These results indicate that SE can relax NE-induced contraction of rabbit blood vessels and increased the changes of rCBF in rats, that relate to the sympathetic nerve system.

  • To determine relationships of biochemical parameters involved in Ca metabolism with eggshell quality, serum Ca level, duodenal and uterine calcium binding protein (CaBP) and uterine carbonic anhydrase (CA) activities were measured using 102-week old hens. Three groups of chickens were selected, those showing high quality (HQ) and low quality (LQ) eggshells and non-laying activity (NE). NE hens exhibited significantly (p < 0.05) lower serum Ca levels than laying hens. HQ and LQ hens were not different in the Ca level, indicating that serum Ca level was not good indicator of hen's ability to produce different quality eggshells. Duodenal CaBPs was highest in HQ and lowest in NE (p < 0.10). Uterine CaBPs of LQ and NE were not different and lower significantly (p<0.10) than that of HQ, suggesting that CaBP played an important role in determining eggshell quality. Uterine CA activities of the three groups were significantly different (p < 0.01) ; highest in HQ and lowest in NE, suggesting intimate relationship between CA and Eggshell quality.

  • The light output of the NE213 liquid scintillator to electrons and protons was measured by coincidence spectrometer which employs the time of flight technique. The proton energies (3.2Mev, 4Mev, 5Mev, 6Mev) represent the kinetic energies of recoil protons from elastic scattering of a polyenergetic neutron source Am-Be (about 2-9 Mev) at angle of 45$^{\circ}$ and 60$^{\circ}$. The response of the NE213 liquid scintillator to protons was varied nonolinearly as the energy increased. while the response to electrons was varied linearly. The light intensity produced by electrons was relatively larger than that of protons in the rate of about three times when the same energy was introduced. The results of the light output to protons were similar to those of Batchelor et al.

  • Various concentrations of whey protein isolate (WPI), such as 0.1, 0.5, 1.0, 2.5, and 5.0%(w/v), containing 1.0%(w/v) eugenol were prepared by high speed homogenization to formulate nanoemulsions (NEs) and to investigate their antimicrobial activity. The results showed that particle size decreased according to increases in WPI concentration. Similarly, the ${\zeta}$-potential value was reduced to a negative charge when using WPI concentrations >0.1%(w/v). In contrast, no significant differences in particle size were observed during 1 mon of storage, except for the 0.1%(w/v) WPI NE. The ${\zeta}$-potential value depended on the increase in WPI concentration and storage duration, except for NE1 and NE5, suggesting that a low or high concentration of emulsifier was not effective for maintaining the droplet form of the eugenol NE. The results of an antibacterial effect investigation indicated that the growth of Escherichia coli was inhibited based on an increase in eugenol concentration in all NE formulations. Moreover, a membrane permeability study showed that total leakage content increased according to incubation time.

  • Quasiclassical trajectory (QCT) calculations of Ne + ${H_2}^+$ reaction have been carried out on the adiabatic potential energy surface of the ground state $1^2$ A'. The reaction probability of the title reaction for J = 0 has been calculated, and the QCT result is consistent with the previous quantum mechanical wave packet result. Quasiclassical trajectory calculations of the four polarization-dependent differential cross sections have been carried out in the center of mass (CM) frame. The P(${\theta}_r$), P(${\phi}_r$) and P(${\theta}_r$, ${\phi}_r$) distributions, the k-k'-j' correlation and the angular distribution of product rotational vectors are presented in the form of polar plots. Due to the well in $1^2$ A' PES, the reagent vibrational excitation has greater influence on the polarization of the product rotational angular momentum vectors j' than the collision energy.

  • The molecule possessing ankyrin-repeats induced by lipopolysaccharide (MAIL) protein is a novel member of the $Ikappa{\beta}$ family. In the present study, we examined the effect of norepinephrine (NE) on MAIL mRNA expression in primary cultured mouse hepatocytes and non-parenchymal liver cells. MAIL mRNA expression in hepatocytes and non-parenchymal liver cells was not directly influenced by NE. However, MAIL mRNA expression in hepatocytes was significantly induced by incubation with a culture medium of non-parenchymal liver cells, treated with NE. Pretreatment with an interleukin (IL)-1 receptor antagonist significantly attenuated the stimulatory effect of the medium. Moreover, exogenous $IL-1{\beta}$ induced MAIL mRNA expression in hepatocytes, while IL-6 and tumor necrosis factor $\alpha$ did not. The concentration of $IL-1{\beta}$ in the medium of non-parenchymal liver cells was significantly increased after NE-treatment. These results suggest that NE can induce MAIL mRNA expression in hepatocytes through $IL-1{\beta}$, released from non-parenchymal liver cells.

  • In this study, a nanoemulsion formulation for encapsulating turmeric extract was developed and its physicochemical characteristics including particle diameter, zeta potential, polydispersity index, and stability were determined. The turmeric nanoemulsion (TE-NE) droplets exhibited small diameter (165 nm), low PDI (0.17), and high zeta potential (-31.80 mV), all desirable characteristics in nanoemulsions, as well as stability in a wide range of pH. The TE-NE was spray-dried as a means to allow its incorporation into food products and reduce potential transport and storage costs. The resulting powder exhibited a pale yellowish appearance and had a curcuminoids content of 0.39 mg/g. The spray-dried TE-NE powder was incorporated into minced pork to make canned ham, and the sensory characteristics of the ham were evaluated. As a result, the canned ham incorporating TE-NE powder received the same overall acceptability score as the control, and only exhibited slight yellowing. By contrast, ham incorporating turmeric extract exhibited substantial yellowing, and its appearance was considered less acceptable by the panelists. Therefore, the TE-NE formulation could be incorporated into canned ham and other meat products without substantially affecting their sensory qualities.

  • The purpose of this study were to 1) determine the analgesic effect of 632.8 nm of helium-neon (He-Ne) laser stimulation on acupuncture point in rat and 2) determine the reversal of analgesic effect by naloxone injection. Eighteen Sprague-Dawley rats were devided into three groups : control (n=6) : laser (n=6), laser stimulation at $3.58\;J/cm^2$ ; and naloxone (n=6), 1 mg/kg of naloxone chloride inject into peritoneum before laser stimulation at $3.63J/cm^2$. Tail-flick latency were measured pretreat and posttreat with hot plate $(55^{\circ}C)$. Data were analyzed using one-way ANOVA and paired t-teat for tail-flick latency. No significant change was noted in the tail-flick latency in either control or naloxone groups. But significant increased in tail-flick latency in taller group. The results suggest that He-Ne laser induced analgesic effect, and endogenous opioids may be involved in He-Ne laser induced analgesia.
