Tree growth and vitality in forest shows seasonal changes. So, in order to detect forest damage accurately, we have to use satellite images before and after damages taken at the same season. However, temporal resolution of high or medium resolution images is very low,so it is not easy to acquire satellite images of the same seasons. Therefore, in this study, we estimated spectral information of the same DOY using time-series Landsat images and used the estimates as reference values to assess forest damages. The study site is Hwasun, Jeollanam-do, where forest damage occurred due to hail and drought in 2017. Time-series vegetation index (NDVI, EVI, NDMI) maps were produced using all Landsat 8 images taken in the past 3 years. Daily normal vegetation index maps were produced through cloud removal and data interpolation processes. We analyzed the difference of daily normal vegetation index value before damage event and vegetation index value after event at the same DOY, and applied the criteria of forest damage. Finally, forest damage map based on daily normal vegetation index was produced. Forest damage map based on Landsat images could detect better subtle changes of vegetation vitality than the existing map based on UAV images. In the extreme damage areas, forest damage map based on NDMI using the SWIR band showed similar results to the existing forest damage map. The daily normal vegetation index map can used to detect forest damage more rapidly and accurately.

In this paper, we propose a method of measuring bone mineral density in a peripheral-type clinical X-ray CT using a phantom, and we propose a method of classifying osteoporosis using bone mineral density and bone structure parameters together. It segments the trabecular bone region and cortical bone region for the six sections of the phantom and calculates the average HU value of the segmented regions. By using these values, it derives an expression converting HU value to bone mineral density. It segments trabecular bone of 1 cm region in the end part of distal radius and extracts the bone mineral density and structural parameters for the trabecular bone region. We extracted bone mineral density and structural parameters for the 18 subjects each of normal and osteoporotic group. We carried out classification experiments using three classification methods; SAD, SVM, ANN. The sensitivity, specificity, accuracy, positive predictive value, negative predictive value, likelihood ratio of the classification was improved in the order of ANN, SVM and SAD. Also, The sensitivity, specificity, accuracy, positive predictive value, negative predictive value, likelihood ratio of the classification was improved when we use the bone mineral density and structural parameters together.

The value embodied by "Ascending to Heaven and Being an Immortal" (Yuhua Dengxian in Chinese) implies the core gist of Daoist culture as well as its ultimate value. From the perspective of Philology, each word, "Yu", "Hua", "Deng", and "Xian" benefits us through a philosophy of life, learning skills, the pursuit of the mysteries of Daoist immortality, and the ways of life characteristics and spiritual transcendence. "To become an immortal" is becoming adept at life. "Yuhua" refers to learning transcendental skills, and "Deng" expresses the promotion of life. "Ascending to Heaven and Becoming an Immortal" integrates the goal- oriented values of Daoist Culture, learning transcendental skills, and the state of being alive into a unified whole. Namely, it is the perfect combination of an adept's supreme pursuit of value and zenith of life. By way of contrast, in Daesoon Jinrihoe, the concepts of "Daesoon" and "Perfected Unification with the Dao" not only advocate "physical and mental transformation" and "spiritual development" for Dao cohorts, but also personal cultivation and service to society, and participation in "The Creation of an Earthly Paradise." These are unified under the ideal humanistic value of "the earthly paradise of the Later World."

This study was conducted on 101 patients who visited hospital for abdominal ultrasonography from May 2020 to December 2020. The purpose of this study was to find out the elasticity according to the ultrasound images (echo pattern, splenomegaly, hepatitis) during the ultrasound examination using the shear wave elastography. The shear wave elastography value of the normal group of the echo pattern was 5.75±1.58 kPa, and the group with the abnormal echo pattern was 8.84±4.94 kPa, and the shear wave elastography value of the abnormal group was high (p<0.05). In normal spleen size, hepatic elasticity value was 6.33±2.54 kPa, and hepatic elasticity value of splenomegaly was 13.73±5.48 kPa. In the case of splenomegaly, the liver elasticity value was high, and there was a statistically significant difference (p<0.05). As the spleen size increased, the liver elasticity value increased by 1.485 times, and as hepatitis progressed, the liver elasticity value increased by 1.573 times (p<0.05). As a result of analysis of concordance between ultrasound imaging findings and shear wave elastography, the Kappa value was found to be as high as 0.922 (p<0.05), which showed high concordance between the two test methods. Additional comparisons of liver elasticity values in shearwave elastography tests along with liver ultrasound findings are thought to be of great help in diagnosing liver fibrosis.

Objectives : One of the most important cause of spondylolisthesis is it's epidemiological structure and L5's stability takes a significant role. The purpose of this study is to assess the difference of the Tuffier's line among of Spondylolythesis patients. Methods : We analyzed the Anterior view of lumbar spine checked at erect position on 60 patients who had been diagnosed as spondylolythesis. We investigated the Tuffier's Line on X-ray film. Results and Conclusions : Age distribution was 15 to 66 and the average was 47.81. Men were 19 cases(31.6%) and women were 41 cases(68.4%). Compared to men, women were more exposed to spondylolisthesis and for the age distribution, 50's showed the biggest portion. Group of normal people showed proportion of 14.3% at L4, 44% at L4/5 and 41.7% at L5 each. And group of patients showed proportion of 48.4% at L4, 35% at L4/5 and 51.6% at L5 each. Comparing these results, significance probability was 0.004(<0.05) which was significant. As the results of comparing the relation between L4/5 and L5/S1 patients, Normal group showed average of 3.33 which were close to L4/5. When there are spondylolisthesis at L4/5, averege was 3.33, placed at lower part of the vertebra body. When there are spondylolisthesis at L5/S1, averege was 3.566, placed between lower part of the veterbra body of L4 and L4/5. The p value of Normal group and L4/5 spondylolisthesis patient group was 0.022(p<0.05) which was significant. But the p value of Normal group and L5/S1 spondylolisthesis patient group was 0.0239 which was not significant. Also p value of L4/5 spcndylolisthesis patient group and L5/S1 spondylolisthesis patient group was 0.721 which was also not significant.

The purpose of this study is to present the reference values for cardiac size and cardiothoracic ratio change, normal range and diagnosis of cardiovascular disease in pregnancy and non pregnancy of normal Korean women using chest X-ray. The subjects of this study were 58 women, who were read as normal by chest radiologist, had chest radiography taken on both last month of pregnancy, pre-pregnancy and within 2 years following delivery. In this study, we defined the last month of pregnancy as pregnancy and before or post pregnancy as non-pregnancy. CS and CTR were measured by two radiological technologist who had clinical experience more ten years with Danzer's method. Statistical methods were paired t-test and one-way ANOVA. Significance level ${\alpha}$ was 0.05 and p-value 0.05 or less was statistically significant. For pregnancy, the mean of left and right cardiac size was $40.11{\pm}8.73mm$ and $89.51{\pm}11.9mm$, CS was $128.60{\pm}13.15mm$, CTR was $44.51{\pm}4.21%$. In non pregnancy, $36.50{\pm}8.18mm$ and $77.68{\pm}13.1mm$. CS and CTR were $114.18{\pm}14.28mm$ and $42.03{\pm}4.04%$. Both pregnancy and non pregnancy, the difference of the mean value in left and right cardiac size, CS and CTR were statistically significant (p<0.01). but comparing mean on age, height and weight, the difference of the mean value between groups was not (p>0.05). In the result of this study, the mean size of CS increased by 12.6% in pregnancy($128.60{\pm}13.15mm$) compared to the non pregnancy($114.18{\pm}14.28mm$), and increased by 9.8% in the right side of the heart and 15.2% in the left side. The mean size of CTR increased about 5.9% in pregnancy ($44.5{\pm}4.21%$) compared to non pregnancy($42.03{\pm}4.04%$).

Objectives: The objective of this study was to examine the effects of osmotic-controlled release oral delivery system methylphenidate on changes in regional cerebral blood flow (rCBF) in children with attention-deficit hyperactivity disorder (ADHD) using single photon emission computed tomography (SPECT). Methods: A total of 26 children with ADHD (21 boys, mean age: $9.2{\pm}2.05$ years old) were recruited. Each ADHD participant was examined for changes in rCBF using technetium-99m-hexamethylpropylene amine oxime brain SPECT before and after 8 weeks methylphenidate medication. Brain SPECT images of pediatric normal controls were selected retrospectively. SPECT images of ADHD children taken before medication were compared with those of pediatric normal controls and those taken after medication using statistical parametric mapping analysis on a voxel-wise basis. Results: Before methylphenidate medication, significantly decreased rCBF in the cerebellum and increased rCBF in the right precuneus, left anterior cingulate, right postcentral gyrus, right inferior parietal lobule and right precentral gyrus were observed in ADHD children compared to pediatric normal controls (p-value<.0005, uncorrected). After medication, we observed significant hypoperfusion in the left thalamus and left cerebellum compared to pediatric normal controls (p-value<.0005, uncorrected). In the comparison between before medication and after medication, there was significant hyperperfusion in the superior frontal gyrus and middle frontal gyrus and significant hypoperfusion in the right insula, right caudate, right middle frontal gyrus, left subcallosal gyrus, left claustrum, and left superior temporal gyrus after methylphenidate medication (p-value<.0005, uncorrected). Conclusion: This study supports dysfunctions of fronto-striatal structures and cerebellum in ADHD. We suggest that methylphenidate may have some effects on the frontal lobe, parietal lobe, and cerebellum in children with ADHD.
