Ascites is the accumulation of fluid in the peritoneal cavity, and it is generally allied with liver disease like cirrhosis of the liver. The ascites is commonly associated with liver cirrhosis, malignancy, or cardiovascular disease today. The liver cirrhosis is the most significant cause of ascites in developed countries as per the available data. In the modern medicine system, the treatment includes the restriction of sodium intake, use of diuretics, and paracentesis done in severe cases. There are many side effects of synthetic chemical diuretics, and their long-term use is not recommended. The alternative medicine like Unani system of medicine provides natural diuretics and drugs which also have protective effects on kidney, liver and other internal organs. It is well known in all drug systems that the prognosis is poor in ascites, but the use of Unani herbal medicines can minimize the side effects caused by synthetic chemical diuretics. The natural herbs used for the management of ascites have fewer side effects as compared to synthetic drugs. The natural drugs can be used for longer duration and provide some dietary supplement which improves the quality of life. This review addressed the thorough treatment of ascites by natural diet and medications.

Objectives This study verified the clinical effectiveness of Qigong exercise therapy for individuals with hypertension. Methods Ten electronic databases were used for information retrieval. Only randomized controlled trials (RCTs) using Qigong exercise therapy as a treatment for hypertension were included in this study. Cochrane risk of bias tool was used to assess the methodological quality of each RCT. Results After a thorough review, six RCTs were deemed eligible. These studies were divided into two groups: Qigong vs. no intervention and Qigong plus anti-hypertensive drug vs. anti-hypertensive drug alone. Among the six RCTs, four studies were Qigong vs. no intervention, and two studies were Qigong plus anti-hypertensive drug vs. anti-hypertensive drug alone. The meta-analysis demonstrated that adding Qigong exercise to anti-hypertensive drug treatment lowers diastolic blood pressure more than the anti-hypertensive drug alone. Conclusions Although Qigong exercise is not widely used in the Korean medical field, the results of this study demonstrated the necessity of exercise while controlling hypertension. However, the number of included studies was small, with their high risk of bias. In conclusion, although it is difficult to determine whether Qigong exercise lowers blood pressure in hypertensive patients, exercise including Qigong must be parallel with the intake of anti-hypertensive drugs.

Objectives The purpose of this study is to identify the characteristics of atopic dermatitis patients based on the personal health records (PHR) according to age and Sasang Constitution, and to find basic data for daily life management using the personal health record. Methods We analyzed the characteristics of atopic dermatitis patients based on PHR (symptoms, emotional state, SCORAD Index, five viscera weakness questionnaire, etc.), and Sasang Constitution collected for 6 weeks in 34 patients (or guardians). Results Each item of the SCORAD Index score in children and adolescents showed that children and adolescents have significantly higher edema than adults. However, repeated measurement of the SCORAD Index showed a significant positive improvement over time regardless of age and constitution. In terms of the symptoms of atopic dermatitis, there was a significant correlation between age and swelling, quality of life and effusion, pruritus (itch) and sleep disturbance in relation to the general characteristics of the subject. In the five visceral weakness scores, adults had significantly higher spleen weakness, liver weakness, kidney weakness scores than in children and adolescents. All results showed a high tendency to have a high lung weakness score, which was more pronounced in children and adolescents. Conclusion This study is meaningful to confirm the correlation between SCORAD Index items related to the symptoms of atopic dermatitis, and to identify trends for specific items by ages and Sasang Constitution.

Objectives: To review and analyze clinical and preclinical evidence of effectiveness, safety, and underlying mechanisms of yokukansan (YKS), a herbal medicine, in alleviating aggression. Methods: Classical records on YKS were searched in the Korean Traditional Medicine Knowledge Database (KTMKD). By searching five electronic databases, prospective clinical studies and preclinical studies of YKS for alleviating aggression/agitation published up to March 30, 2021 were included. Results: Only two classical records on YKS were found from the KTMKD. A total of 11 clinical studies and 15 preclinical studies were found from the five electronic databases. Among 11 clinical studies, seven enrolled patients with dementia and four enrolled patients with other neuropsychiatric disorders. Most clinical studies reported significant improvement in one or more outcomes related to aggression in the YKS group after treatment. Among 15 preclinical studies, all studies except two reported a significant decrease in aggression/agitation-related behavior of YKS or yokukansankachimpihange. Suggested underlying mechanisms of YKS or yokukansankachimpihange for aggression/agitation in these studies included regulation of serotonin receptor, amelioration of abnormal glucocorticoid level related to the hypothalamic-pituitary-adrenal axis, regulation of orexin secretion, amelioration of degeneration in brain cells including glia cells, and suppression of excessive glutamatergic or dopaminergic activity. Conclusions: There were some clinical and preclinical evidence supporting the effectiveness and safety of YKS for alleviating aggression. Given that aggression is the most frequent and destructive symptoms of behavioral and psychological symptoms of dementia, applicability of YKS as a herbal medicine should be further investigated in future high-quality research.

Recently, with the development of IoT technology, the number of farms using smart farms is increasing. Smart farms monitor the environment and optimise internal environment automatically to improve crop yield and quality. For optimized crop cultivation, researches on predict crop productivity are actively studied, by using collected agricultural digital data. However, most of the existing studies are based on statistical models based on existing statistical data, and thus there is a problem with low prediction accuracy. In this paper, we use various predition models for predicting the production and sales profits, and compare the performance results through models by using the agricultural digital data collected in the facility horticultural smart farm. The models that compared the performance are multiple linear regression, support vector machine, artificial neural network, recurrent neural network, LSTM, and ConvLSTM. As a result of performance comparison, ConvLSTM showed the best performance in R2 value and RMSE value.

The Nile tilapia Oreochromis niloticus, Atlantic salmon Salmo salar, rainbow trout Oncorhynchus mykiss, olive flounder Paralichthys olivaceus, common carp Cyprinus carpio, grass carp Ctenopharyngodon idella and rohu carp Labeo rohita are farmed commercially worldwide. Production of these important finfishes is rapidly expanding, and intensive culture practices can lead to stress in fish, often reducing resistance to infectious diseases. Antibiotics and other drugs are routinely used for the treatment of diseases and sometimes applied preventatively to combat microbial pathogens. This strategy is responsible for the emergence and spread of antimicrobial resistance, mass killing of environmental/beneficial bacteria, and residual effects in humans. As an alternative, the administration of probiotics has gained acceptance for disease control in aquaculture. Probiotics have been found to improve growth, feed utilization, immunological status, disease resistance, and to promote transcriptomic profiles and internal microbial balance of host organisms. The present review discusses the effects of single and multi-strain probiotics on growth, immunity, heamato-biochemical parameters, and disease resistance of the above-mentioned finfishes. The application and outcome of probiotics in the field or open pond system, gaps in existing knowledge, and issues worthy of further research are also highlighted.

The purpose of this paper was to identify a method to improve received noise in a specific frequency band, caused by RF radiation signals during aircraft operation. The communication equipment of the aircraft is critical to the performance and safety of the flight mission, as it is responsible for the function of internal and external communications. Noise-free, clean communication quality, as well as transmission and receiving functions have to be implemented. Thus, the cause analysis of the reception noise in a specific frequency band, was analyzed through trouble shooting. The receiving noise due to the RF radiation signal emitted from the subsystem unit inside the aircraft, was improved by shielding with a CAP with electroless nickel plating applied. Additionally, the measurement and verification results of the improvement method are also described.

The high internal resistance (R_int) that develops across the sediment microbial fuel cells (SMFC) limits their power production (~4/10 mW m^-2) that can be recovered from an initial oil-contaminated sediment (OCS). In the anolyte, R_int is related to poor biodegradation activity, quality and quantity of contaminant content in the sediment and anode material. While on the catholyte, R_int depends on the properties of the catholyte, the oxygen reduction reaction (ORR), and the cathode material. In this work, the main factors limiting the power output of the SMFC have been minimized. The power output of the SMFC was increased (47 times from its initial value, ~4 mW m^-2) minimizing the SMFC R_int (28 times from its initial value, 5000 ohms), following the main modifications. Anolyte: the initial OCS was amended with several amounts of gasoline and kerosene. The best anaerobic microbial activity of indigenous populations was better adapted (without more culture media) to 3 g of kerosene. Catholyte: ORR was catalyzed in birnessite/carbon fabric (CF)-cathode at pH 2, 0.8M Na₂SO₄. At the class level, the main microbial groups (Gammaproteobacteria, Coriobacteriia, Actinobacteria, Alphaproteobacteria) with electroactive members were found at C-anode and were associated with the high-power densities obtained. Gasoline is more difficult to biodegrade than kerosene. However, in both cases, SMFC biodegradation activity and power output are increased when ORR is performed on birnessite/CF in 0.8 M Na₂SO₄ at pH 2. The work discussed here can focus on bioremediation (in heavy OCS) or energy production in future work.

The exciting advancement related to the "modeling of digital human" in terms of a computational phantom for radiation dose calculations has to do with the latest hype related to deep learning. The advent of deep learning or artificial intelligence (AI) technology involving convolutional neural networks has brought an unprecedented level of innovation to the field of organ segmentation. In addition, graphics processing units (GPUs) are utilized as boosters for both real-time Monte Carlo simulations and AI-based image segmentation applications. These advancements provide the feasibility of creating three-dimensional (3D) geometric details of the human anatomy from tomographic imaging and performing Monte Carlo radiation transport simulations using increasingly fast and inexpensive computers. This review first introduces the history of three types of computational human phantoms: stylized medical internal radiation dosimetry (MIRD) phantoms, voxelized tomographic phantoms, and boundary representation (BREP) deformable phantoms. Then, the development of a person-specific phantom is demonstrated by introducing AI-based organ autosegmentation technology. Next, a new development in GPU-based Monte Carlo radiation dose calculations is introduced. Examples of applying computational phantoms and a new Monte Carlo code named ARCHER (Accelerated Radiation-transport Computations in Heterogeneous EnviRonments) to problems in radiation protection, imaging, and radiotherapy are presented from research projects performed by students at the Rensselaer Polytechnic Institute (RPI) and University of Science and Technology of China (USTC). Finally, this review discusses challenges and future research opportunities. We found that, owing to the latest computer hardware and AI technology, computational human body models are moving closer to real human anatomy structures for accurate radiation dose calculations.
