As Small Intestine Absorptive Epithelium Cells are surrounded by mucus polysaccharide and lymphocytes and mitochondria, they are sensitive to radiation energy. Damaged cells lead to a deficiency of nutrients and the imbalance of electrolyte metabolism, which in turn can becomes a major cause of an intestine tract death. This research observed ultra structures after injecting propolis into the abdominal cavity in order to reveal the radiation damage mechanism and radioprotection effect of intestine absorptive epithelium cells. The result of this research's observation found that stenosis occurred in the small intestine in some tissues 20 days after 5Gy irradiation, their surface turned black, and their elasticity dropped. Through observation with an optical microscope, it was found that the size of the goblet cells decreased, while the paneth granulate cells atrophied and were vacuolated. Observation with an transmission electron microscope(TEM) revealed that while microvill and lysosome were normally observed in jejunum tissues, mitochondria membrane was damaged and uneven surfaces were formed on lymphocytes. The membrane of absorptive epithelium cells hypertrophied in tissues of the ileum, and vacuole was observed. However, the observation after injecting propolis into the abdominal cavity found that mitochondria damage dropped dramatically, and radioprotection effects were to some extent confirmed, considering that glycocalyx of villi was clear, and M cells could be observed.

Recent severe climate changes and extreme weather events have caused the uncommon types of forest ecosystem disturbances such as hails and gypsy moths. This paper describes the analysis of the forest ecosystem disturbances using ISODATA (Iterative Self-organizing Data Analysis Technique Algorithm) with the RapidEye and Sentinel-2 images, regarding the cases of the hail damages in Hwasun in 2017 and the gypsy moth damages in the Chiak Mountain in 2020. In the case of hail damages, the comparison of the June image of this study and the July field survey of the previous study showed that the damage severity increased from June to July as the drought overlapped after the trees were injured by the hails. In the case of gypsy moths, significant leaf damages were found from the image of June, and the damages were mainly distributed at the low-altitude slope near Wonju City. We made sure that satellite remote sensing is a very effective method to detect various and unusual forest ecosystem disturbances caused by climate change. Also, it is expected that the Korean Medium Satellite for Agriculture and Forestry scheduled to launch in 2024 can be actively utilized to monitor such forest ecosystem disturbances.

Several MRI studies have reported reductions in temporal lobe volumes in Alzheimer's disease (AD). Measures have been usually obtained with regions-of-interest (ROI) drawn manually on selected medial and lateral portions of the temporal lobes, with variable choices of anatomical borders across different studies. We used the automated voxel-based morphometry (VBM) approach to investigate gray matter abnormalities over the entire extension of the temporal lobe in 10AD patients (MM5E 22)and 22 healthy controls. Foci of significantly reduced gray matter volume in AD patients were detected in both medial and lateral temporal regions, most significantly in the right and left posterior parahippocarmpal gyri. At a more flexible statistical threshold (P<0.01, uncorrected for multiple comparisons), circumscribed foci of significant gray matter reduction were also detected in the right amygdala/enthorinal cortex, the anterior and posterior borders of the superior temporal gyrus bilaterally, and the anterior portion of the left middle temporal gyrus. These VBM results confirm previous findings of temporal lobe atrophic changes in AD, and suggest that these abnormalities may be confined to specific sites within that lobe, rather than showing a widespread distribution.
