In some urban parks in Tokyo,semi-natural habitat patches are maintained as nature reserves for birds,called bird *** censuses and vegetation surveys were conducted in eight urban parks in Tokyo from December 2015 to July 2016 to determine the effectiveness of bird sanctuaries on avian species *** relationship between avian species composition and environmental conditions was analyzed by partial redundancy analysis(partial RDA)using vegetation variables,number of visitors,presence or absence of reserves within the same park,area of wooded parts,and normalized difference vegetation index(NDVI)in the surrounding *** results of the partial RDA are as follows:(1)Area,lower vegetation cover,higher vegetation cover,tree species composition obtained from detrended correspondence analysis(DCA)on vegetation survey data,and NDVI in the surrounding area were considered as covariates and explained 17.4-33.6%of the total variation in bird species composition,(2)The presence or absence of sanctuary significantly explained bird species compositional variation regardless of season,indicating that the sanctuaries were beneficial for urban avoider species not only in the sanctuaries but also in the surrounding wooded area,and(3)Tree coverage within a 100 m range and leaf litter coverage also influenced avian species *** concluded that bird sanctuaries and other nature reserves can be beneficial to bird conservation,even within *** positive effect of sanctuaries could be due to the limited influence of human presence and the developed vegetation within *** reserves may play the role of core habitats within the studied urban parks.

·AIM:To investigate the efficacy of ripasudil,a Rho kinase inhibitor,in reducing intraocular pressure(IOP)and medication scores of anti-glaucoma drugs in patients with ocular hypertension with inflammation and corticosteroid.·METHODS:The study included 11 patients diagnosed with ocular hypertension with inflammation and corticosteroid,all of whom were prescribed ripasudil eye drops and followed up for at least 2y after the initiation of *** was measured using a non-contact tonometer before enrollment and at each follow-up *** medication score of glaucoma eye drops was calculated for each patient.·RESULTS:The mean IOP(26.4±2.9 mm Hg before treatment)significantly decreased after ripasudil therapy(13.7±3.3 mm Hg at 3mo)and remained stable in the low-teens during the 2-year follow-up period(P<0.0001).A significant decrease in the medication score was observed at 12mo or later after the initiation of ripasudil therapy(P<0.05).Both baseline medication scores and glaucomatous optic disc change rates were significantly higher in the five eyes that required glaucoma surgery during the 2-year observation period than the 10 eyes that did not require surgery.·CONCLUSION:Our results demonstrate the efficacy of ripasudil,in reducing IOP and the medication score over a 2-year treatment period in patients with ocular hypertension with inflammation and *** findings also suggest that ripasudil could reduce the IOP in uveitic glaucoma patients with both lower baseline medication score and lower glaucomatous optic disc change rate.

Differentiated adenocarcinoma of the stomach is classified into gastric or intestinal phenotypes based on mucus expression. Recent advances in mucin histochemistry and immunohistochemistry have highlighted the importance of such a distinction, and it is important clinically to distinguish between gastricand intestinal-type differentiated adenocarcinoma. However, a clinical and pathological diagnosis of this type is often difficult in early gastric cancer because of histological similarities between a hyperplastic epithelium and lowgrade atypia. Furthermore, determining tumor margins is often difficult, even with extensive preoperative examination. It is therefore critical to consider these diagnostic difficulties and different biological behaviors with high malignant potential when treating patients with gastric-type differentiated adenocarcinoma.

The classification of visual human action is important in the development of systems that interact with humans. This study investigates an image-based classifica- tion of the human state while using a walking support system to improve the safety and dependability of these systems. We categorize the possible human behavior while utilizing a walker robot into eight states （i.e., sitting, standing, walking, and five falling types）, and propose two different methods, namely, normal distribution and hidden Markov models （HMMs）, to detect and recognize these states. The visual feature for the state classification is the centroid position of the upper body, which is extracted from the user＇s depth images. The first method shows that the centroid position follows a normal distribution while walking, which can be adopted to detect any non-walking state. The second method implements HMMs to detect and recognize these states. We then measure and compare the performance of both methods. The classification results are employed to control the motion of a passive-type walker （called ＂RT Walker＂） by activating its brakes in nonwalking states. Thus, the system can be used for sit/stand support and fall prevention. The experiments are performed with four subjects, including an experienced physiotherapist. Results show that the algorithm can be adapted to the new user＇s motion pattern within 40 s, with a fall detection rate of 96.25% and state classification rate of 81.0%. The proposed method can be implemented to other abnormality detection/classification applications that employ depth image-sensing devices.
