A 6-month-old thoroughbred filly foal had torticollis and circled towards the right side. A local veterinarian treated her twice using dexamethasone for 1 week but there was little clinical improvement. Needles were inserted into Ting points of both hind limb and one ocular acupoint (shang jiao area from GB01). Injection acupuncture (dexamethasone, twice/week) was used at GV16, GB20, BL10 and LU07, for the neck and head. Acupoint GB34 was added to those points at session 4. In addition, a trigger point in the left neck was injected with 0.2 ml ($200{\mu}g$ of apitoxin) of bee-venom diluted with 1 ml of 2% lidocaine from session 1 to session 3. At session 2, the symptoms had ameliorated a little. At session 3, they were much improved; the right ear was completely normal and the neck could be moved about 60% of normal range. At session 4, nodding was possible and stiffness of the neck was much improved, having returned to about 80% of normal range. Three days after session 4, the symptom of torticollis had disappeared completely and the foal could walk in a straight line. In conclusion, the present patient was a case with equine torticollis which showed favourable therapeutic response by combination of needle-acupuncture plus injection-acupuncture with dexamethasone and apitoxin.

Recently, demands for high-performance flash-based storage devices (i.e., flash SSD) have rapidly grown in social network services, cloud computing, super-computing, and enterprise storage systems. The industry and academic communities made the NVMe specification for high-performance storage devices, and NVMe-based flash SSDs can be now obtained in the market. In this article, we evaluate performance of NoSQL databases that social network services and cloud computing services heavily adopt by using NVMe-based flash SSDs. To this end, we use NVMe SSD that Samsung Electronics recently developed, and the SSD used in this study has performance up to 3.5GB/s for sequential read/write operations. We use WiredTiger for NoSQL databases, and it is a default storage engine for MongoDB. Our experimental results show that log processing in NoSQL databases is a major overhead when high-performance NVMe-based flash SSDs are used. Furthermore, we optimize components of log processing and optimized WiredTiger show up to 15 times better performance than original WiredTiger.

This study describes the reliability of pragmatic combinations of acupuncture points for lateral epicondylalgia (LE) as prescribed by physiotherapists who were experts in acupuncture. Raters (n = 14; 33-59 years) independently prescribed acupuncture points for 30 simulated human patients with LE who were surveyed via a printed questionnaire. The frequency and cooccurrence of acupuncture points prescribed for patients with lateral epicondylitis were assessed. Absolute agreement and Light's kappa (${\kappa}_{Light}$) with 95% confidence interval (CI) were used to quantify the interrater agreement. Raters prescribed 103 unique acupuncture points in different combinations with a median (min-max) of 5 (0-11) acupuncture points. The most prescribed acupuncture point was LI-11 (297 of 420; 71%), and the most common cooccurring acupuncture points were LI-11 and LI-4 (160 of 420; 38%). The absolute agreement for prescribing the acupuncture points ranged from 70% (point GB-20) to 0% (points LI-10, SP-6, LI-11, GB-34, LI-12, and LI-4). Point LR-3 showed the highest interrater reliability for prescribing the acupuncture points [${\kappa}_{Light}=0.112$, 95% CI = (0.055-0.194)], whereas point LI-4 showed the lowest reliability [${\kappa}_{Light}=-0.003$, 95% CI = (-0.024 to 0.024)]. These findings suggest that pragmatic prescriptions of acupuncture points for LE are unreliable among physiotherapists who are experts in acupuncture. Explicit, high-level evidence-based rules for prescribing and teaching combinations of acupuncture points for LE are warranted.

Rice vinegar (RV) is primarily made from fermented rice or rice wine in Korea, China, and Japan. Ten commercially available naturally-fermented rice vinegars produced in Korea (KRV1~4), China (CRV1~2), and Japan (JRV1~4) were comparatively investigated for their physicochemical properties and antioxidant activities. KRV showed a significantly higher total acidity range (5.07~6.27) than both CRV (4.67~4.84) and JRV (4.64~4.84). These acidity ranges corresponded with respective standards of each country: Korea (Food Code), China (GB), and Japan (JAS). Six different organic acids were detected in RVs; acetic acid and succinic acid were the most prominent. Thirty different amino acids were detected in RVs, and main identified amino acids were alanine (KRV), phenylalanine and aspartic acid (CRV), and leucine and alanine (JRV). ${\gamma}-Aminobutyric$ acid was detected at high concentration in KRV1. KRV1 showed maximum total phenolic content, and DPPH and ABTS radical scavenging activities of samples were also determined with significantly increasing tendency. KRV1 (produced from brown rice with aging period of >1 year) exhibited the highest free amino acid content and antioxidant activity as compared to CRV and JRV.

In big data era, fresh data grows rapidly every day. More than 30,000 gigabytes of data are created every second and the rate is accelerating. Many organizations rely heavily on real time streaming, while big data stream computing helps them spot opportunities and risks from real time big data. Storm, one of the most common online stream computing platforms, has been used for big data stream computing, with response time ranging from milliseconds to sub-seconds. The performance of Storm plays a crucial role in different application scenarios, however, few studies were conducted to evaluate the performance of Storm. In this paper, we investigate the performance of Storm under different application scenarios. Our experimental results show that throughput and latency of Storm are greatly affected by the number of instances of each vertex in task topology, and the number of available resources in data center. The fault-tolerant mechanism of Storm works well in most big data stream computing environments. As a result, it is suggested that a dynamic topology, an elastic scheduling framework, and a memory based fault-tolerant mechanism are necessary for providing high throughput and low latency services on Storm platform.

This study presents the estimation of crack depth by analyzing temperatures extracted from thermal images and environmental parameters such as air temperature, air humidity, illumination. The statistics of all acquired features and the correlation coefficient among thermal images and environmental parameters are presented. The concrete crack depths were predicted by four different machine learning models: Multi-Layer Perceptron (MLP), Random Forest (RF), Gradient Boosting (GB), and AdaBoost (AB). The machine learning algorithms are validated by the coefficient of determination, accuracy, and Mean Absolute Percentage Error (MAPE). The AB model had a great performance among the four models due to the non-linearity of features and weak learner aggregation with weights on misclassified data. The maximum depth 11 of the base estimator in the AB model is efficient with high performance with 97.6% of accuracy and 0.07% of MAPE. Feature importances, permutation importance, and partial dependence are analyzed in the AB model. The results show that the marginal effect of air humidity, crack depth, and crack temperature in order is higher than that of the others.

Although canine facial nerve paralysis(FNP) occurs similarly in humans, there is no properly recognized therapy using Western medicine for idiopathic causes. To elucidate therapeutic measures by acupuncture(AP) on canine FNP, we examined the therapeutic effect of injection-AP on the artificially induced canine FNP. Twelve dogs on artificially induced canine FNP were divided into a control group(4 dogs), an experimental dexamethasone-treated group(dexamethasone group, 4 dogs) and an experimental bee venom-treated group(apitoxin group, 4 dogs). Saline (1 ml) was intramuscularly injected into the head muscle after the induction of FNP in the control group. On the other hand, injection-AP with dexamethasone was performed on such acupoints as LI04, LI20, ST02, ST07, TH17, SI18, GB03 and GB34, twice per week after induction of FNP in the dexamethasone group. In addition, injection-AP with $100{\mu}g$ of apitoxin was performed on the same acupoints as the dexamethasone group twice per week after the induction of FNP in the apitoxin group, respectively. The changes of the clinical symptoms of FNP with each treatment during the experimental period were recorded by using clinical scores, respectively. The changes of serum creatine kinase(CK) activities along with each treatment were determined using an autoanalyzer. The significant differences of clinical scores were detected on day 14(p<0.05) in the apitoxin and dexamethasone groups, compared with those in the control group, respectively. However, significant difference was not detected between the apitoxin and dexamethasone groups. Significant differences of serum CK activities were detected on day 7(p<0.05) and day 14(p<0.05) in the dexamethasone and apitoxin groups, compared with those in the control group, respectively. However, significant difference was not detected between the dexamethasone and apitoxin groups. In condition, injection-APs with apitoxin and dexamethasone were all effective for treatment of canine FNP and the therapeutic effect by injection-AP with apitoxin was similar to that of injection-AP with dexamethasone.

Background: Nonalcoholic steatohepatitis (NASH) is one of the chronic inflammatory liver diseases and a leading cause of advanced liver fibrosis, cirrhosis, and hepatocellular carcinoma. The main purpose of this study was to clarify the effects of GBCK25 fermented by Saccharomyces servazzii GB-07 and pectinase, on NASH severity in mice. Methods: Six-wk-old male mice were fed either a normal diet (ND) or a Western diet (WD) for 12 wks to induce NASH. Each group was orally administered with vehicle or GBCK25 once daily at a dose of 10 mg/kg, 20 mg/kg, 100 mg/kg, 200 mg/kg, or 400 mg/kg during that time. The effects of GBCK25 on cellular damage and inflammation were determined by in vitro experiments. Results: Histopathologic analysis and hepatic/serum biochemical levels revealed that WD-fed mice showed severe steatosis and liver injury compared to ND-fed mice. Such lesions were significantly decreased in the livers of WD-fed mice with GBCK25 administration. Consistently, mRNA expression levels of NASH-related inflammatory-, fibrogenic-, and lipid metabolism-related genes were decreased in the livers of WD-fed mice administered with GBCK25 compared to WD-fed mice. Western blot analysis revealed decreased protein levels of cytochrome P450 2E1 (CYP2E1) with concomitantly reduced activation of c-Jun N-terminal kinase (JNK) in the livers of WD-fed mice administered with GBCK25. Also, decreased cellular damage and inflammation were observed in alpha mouse liver 12 (AML12) cells and RAW264.7 cells, respectively. Conclusion: Administration of GBCK25 ameliorates NASH severity through the modulation of CYP2E1 and its associated JNK-mediated cellular damage. GBCK25 could be a potentially effective prophylactic strategy to prevent metabolic diseases including NASH.
