Septic tenosynovitis of the digital flexor tendon sheath (DFTS) is a potentially career-ending and life-threatening problem in horses. This study aimed to describe the outcomes of tenoscopy for the treatment of acute septic digital flexor tenosynovitis in horses. Tenoscopy was performed on 13 Thoroughbred horses with acute septic tenosynovitis of the DFTS. Surgical time was 56-148 min (mean 85.6 min, median 84.0 min). In the synovial fluid analysis, mean white blood cell count, mean neutrophil proportion, and mean total protein were $42.9{\times}10^3cells/{\mu}l$ (range, $7.2-109.5cells/{\mu}l$), 89.5% (range, 68-97%), and 4.0 g/dl (range, 2.5-5.2 g/dl), respectively. Microbial growth in the synovial fluid culture was detected in 2 of 11 horses. All horses survived and returned to their intended use without complications. The present study demonstrated that the tenoscopy is useful for treating acute septic tenosynovitis of the DFTS in horses.

Objectives: Hwa-byung is a mental illness. It is also known as a Korean culture-related syndrome. In traditional Korean medicine, Sihogayonggolmoryeo-tang is used to treat Hwa-byung related neuropsychiatric symptoms. The purpose of this research was to examine the effect of Sihogayonggolmoryeo-tang on Hwa-byung. Methods: A multicenter, randomized, double-blinded, placebo-controlled study was performed for 160 patients with Hwa-byung. Patients were divided into a Sihogayonggolmoryeo-tang group and a placebo group. Treatment period was 8 weeks. Hamilton Rating Scale for Anxiety (HAM-A), Likert scale for major symptoms of Hwa-byung, Hwa-byung Scale (HBS), Korean Beck Depression Inventory (K-BDI), Korean State-Trait Anxiety Inventory (K-STAI), Korean State-Trait Anger Expression Inventory (K-STAXI), and Korean WHO Quality of Life Scale Abbreviated Version (WHOQOL-BREF) were used to evaluate the effect of Sihogayonggolmoryeo-tang on Hwa-byung. We also used an Instrument of Pattern Identification for Hwa-Byung to evaluate different responses for six patterns of patients. Results: Scores of all the measurements improved significantly for each group, showing no significant differences between the two groups. In the case of deficiency of both Qi and blood pattern, the Sihogayonggolmoryeo-tang group showed a significant decrease in the HAM-A score compared to the placebo group. Conclusions: The effect of Sihogayonggolmoryeo-tang on Hwa-byung did not exceed that of the placebo. Further studies involving more elaborate pattern identification are needed.

Most angiogenesis assays are performed using endothelial cells. However, blood vessels are composed of two cell types: endothelial cells and pericytes. Thus, co-culture of two vascular cells should be employed to evaluate angiogenic properties. Here, we developed an in vitro 3-dimensional angiogenesis assay system using spheroids formed by two human vascular precursors: endothelial colony forming cells (ECFCs) and mesenchymal stem cells (MSCs). ECFCs, MSCs, or ECFCs+MSCs were cultured to form spheroids. Sprout formation from each spheroid was observed for 24 h by real-time cell recorder. Sprout number and length were higher in ECFC+MSC spheroids than ECFC-only spheroids. No sprouts were observed in MSC-only spheroids. Sprout formation by ECFC spheroids was increased by treatment with vascular endothelial growth factor (VEGF) or combination of VEGF and fibroblast growth factor-2 (FGF-2). Interestingly, there was no further increase in sprout formation by ECFC+MSC spheroids in response to VEGF or VEGF+FGF-2, suggesting that MSCs stimulate sprout formation by ECFCs. Immuno-fluorescent labeling technique revealed that MSCs surrounded ECFC-mediated sprout structures. We tested vatalanib, VEGF inhibitor, using ECFC and ECFC+MSC spheroids. Vatalanib significantly inhibited sprout formation in both spheroids. Of note, the $IC_{50}$ of vatalanib in ECFC+MSC spheroids at 24 h was $4.0{\pm}0.40{\mu}M$, which are more correlated with the data of previous animal studies when compared with ECFC spheroids ($0.2{\pm}0.03{\mu}M$). These results suggest that ECFC+MSC spheroids generate physiologically relevant sprout structures composed of two types of vascular cells, and will be an effective pre-clinical in vitro assay model to evaluate pro- or anti-angiogenic property.

Bull-boxing in South Korea is a form of competitions in which bulls measure their strength with each other in the form of pushing by putting their heads together. Bull-boxing has been admitted after being designated as a play culture by the government because it does not cause great injuries to animals' bodies and has strong positive aspects such as contributing to livestock farmers' leisure activities, encouragement of animal husbandry, and communities' economic development. However, bull-boxing sometimes causes damage to the head and horns due to the heavy bodies. According to the results of examinations of these damage cases, damage that caused irregular shapes of the base of horns was identified in 31.5% of fighting bulls. The damage to horns is thought to have been caused by the great forces of fighting bulls repeatedly imposed to each other's horns during bull-boxing that caused minute fractures leading to damage to the blood vessels inside the horns resulting in the blocking of delivery of nutrients to the horns causing the deformation of the horns into abnormal shapes. Since bulls' bodies are injured during bull-boxing although the injuries are small as bull-boxing is mainly conducted by pushing, animal protection groups regard bull-boxing as cruelty to animals and request to stop bull-boxing. The present study aims to develop animal welfare type headgears that can protect bulls' horns and heads in order to protect fighting bulls during bull-boxing in terms of animal protection and welfare.

In this study, the bacteria which could hydrolyze the fibrin produced through the blood coagulation mechanism in the human body, were isolated from Chungkookjang. The KCK-7 strain was selected among the isolated bacteria as the best strain for fibrinolytic activity. It was spore forming and Gram positive. $C_{150}$ anteiso fatty acid and $C_{150}$ iso fatty acid were 40.85% and 19.47%, respectively as major component among its cellular fatty acid composition. It showed the similarity of 63.6%, compared with standard strain. It was thus identified to be Bacillus subtilis according to Bergey's manual of systematic bacteriology and its fatty acid profiles af Gas chromatography. The optimum culture temperature and pH were $37^{\circ}C$ and 8 for the production of fibrinolytic enzyme by Bacillus subtilis KCK-7.

A simple and easy modification of AST by disk diffusion was tested for the detection of induced clindamycin resistant Staphylococci and their antimicrobial susceptibility at the same time. The incidence of inducible clindamycin resistant staphylococci in blood culture and their MIC characterization at Seoul National University Hospital was analyzed by an AST contained disk approximation test (D-zone test) and Etest, respectively. Of the total 309 staphylococcal isolates, 139 (45%) isolates presented constitutive resistance to ERY and CLI (ERY-R, CLI-R phenotype), and 59 were ERY-I/R and CLI-S phenotypes. Of the 59 isolates, 19 (32%) isolates were inducible resistant to CLI. The incidence was higher in S. aureus (66.7%) than coagulase-negative staphylococci (CNS, 26.0%). Especially, methicillin-resistant staphylococci (MRSA, 100%; MRCNS, 45.5%) presented higher inducibility than methicillin susceptible (MSSA, 50%; MSCNS, 20%). For most of the inducible clindamycin resistant staphylococci (15 of 19 isolates), their ERY MIC were high (>$128_{\mu}g/mL$) and were methicillin resistant. The remaining 4 isolates were methicillin susceptible and their ERY MIC were of intermediate concentrations ($1-4_{\mu}g/mL$). We concluded that suscetibility testing of staphylococci, especially methicillin resistant, should include the D-zone test.

Ochrobactrum anthropi, previously known as Achromobacter species biotypes 1 and 2 (CDC groups Vd-1, Vd-2), belong to the groups of non-Enterobacteriaceae- nonfermentative Gram negative bacilli. Achromobacter is not presently a recognized genus. Achromobacter xylosoxidans has been transferred to genus Alcaligenes as A. xylosoxidans subsp. xylosoxidans, and "Achromobacter" sp. group Vd has been named Ochrobactrum anthropi. O. anthropi was isolated from a blood culture. Organisms were identified as O. anthropi by use of the biochemical test and the VITEK 2(bioMerieux, USA). The Organism was susceptible only to colistin, imipenem, meropenem, and tetracycline, but were resistant to amikacin, aztreonam, cefepime, ceftazidime, cefpirome, ciprofloxacin, gentamicin, isepamcin, netilmicin, pefloxacin, piperacillin, piperacillin/tazobactam, ticarcillin, ticarcillin/clavulanic acid, tobramycin, and trimethoprim/sulfamethoxazole. We report the clinical and microbiologic characteristics of O. anthropi infection in the patient. This is the first case of O. anthropi infection after using a plant as medicine at Chosun University Hospital.

Power is the driving force of society, and the generation of power is inevitable. as long as society is rganized hierarchically. According to Michael Foucault's discourse modern power operates as a mechanism of 'panopticon', a system that monitors the 'body' of man through discipline. Moreover. fashion as acts as a symbol of beauty that continues to co-exist with power for the purpose of exposing status and authority, and for displaying the trends within a culture. So, it is necessary to study fashion design according to the changing power structure that exists in society. The aim of this study is to suggest types of creative fashion design process by visualizing the Foucault's power discourse through the image associative action. The four types of creative fashion design that have been drawn by visualizing Foucault's power discourse are as follow: disciplinary power, imprisonment power and knowledge power. The first type of fashion design method is to emphasize the shoulder by using shoulder pads, strings, tabs, and incisions in the clothing. The second method is to expose the body by using see-through material and manipulating its composition to expose the body. Third method is to borrowing elements of underwear. Fourth method is to utilize patterns that represent power, such as weapons, bones, blood, muscles, skulls, and various human imagesin the clothing. Through this study we expect to utilize creative fashion design to visualize concepts of the humanities, such as philosophical discourse.

We predict the mortality of the elderly patients visiting the emergency department who are over 65 years old using Feed Forward Neural Network (FFNN) and Convolutional Neural Network (CNN) respectively. Medical data consist of 99 features including basic information such as sex, age, temperature, and heart rate as well as past history, various blood tests and culture tests, and etc. Among these, we used random forest to select features by measuring the importance of features in the prediction of mortality. As a result, using the top 80 features with high importance is best in the mortality prediction. The performance of the FFNN and CNN is compared by using the selected features for training each neural network. To train CNN with images, we convert medical data to fixed size images. We acquire better results with CNN than with FFNN. With CNN for mortality prediction, F1 score and the AUC for test data are 56.9 and 92.1 respectively.

Nocardiosis is an acute, subacute or chronic infection, which usually introduced through the respiratory tract resulting pneumonia, and may develop a disseminated infection, especially subcutaneous abscess and/or CNS infection. It is usually affects the immunocompromized host and may be fatal unless early diagnosis and adequate treatment are performed. There have been only several case reports of nocardial infection in Korea. Nocardiosis is so unfamiliar to many physicians that may be misdiagnosed as pneumonia, tuberculosis, or neoplasm. We have experienced a case of nocardiosis from a patient who had been treated as pneumonia and tuberculosis at first. The 57-year-old male patient had fever, chill, dyspnea and blood tinged purulent sputum for 20 days. Under the impression of bacterial pneumonia, broad spectrum antibiotics were administered for more than 3 weeks without clinical improvement. Although antituberculous drugs began to be administered after acid fast bacilli were found in bronchial aspirate by bronchoscopy, the nocardial infection was suspected due to no clinical response toward antituberculous therapy and the occurrence of multiple subcutaneous abscesses on scalp. The diagnosis was made by modified Ziehl-Neelson stain and culture of the sputum and pus. Nocardia asteroides was identified. After 25 days of trimethoprim-sulfamethoxazole treatment, the patient was much improved and discharged.
