Deep learning based methods achieve state-of-the-art accuracy, however, they typically rely on supervised training with large labeled datasets. It is known in many medical applications that labeling medical images requires significant expertise and much time, and typical hand-tuned approaches for data augmentation fail to capture the complex variations in such images. This paper proposes a 3D image augmentation method to overcome these difficulties. It allows us to enrich diversity of training data samples that is essential in medical image segmentation tasks, thus reducing the data overfitting problem caused by the fact the scale of medical image dataset is typically smaller. Our numerical experiments demonstrate that the proposed approach provides significant improvements over state-of-the-art methods for 3D medical image segmentation.

Objective: This research was performed to investigate the efficacy of complex rehabilitation combined with pharmacopuncture treatment for the children with neuromotor system diseases. Methods: Fifty (50) patients aged from 5 to 15 yr old were compared. Twenty (20) patients received conventional treatments and complex rehabilitation as a control group, and fifty (50) patients received complex rehabilitation with pharmacopuncture. At their first visits, the patients had checkups and neurological scales, and after 10 days of pharmacopuncture treatments and 55 days of rehabilitation, they also took neurological scales. We studied the pre and post effects of the treatment group. Results: The number of patients with ankle joint disorder and contracture, knee joint contracture, steppage, horsey hoof, shoulder weakness and contracture, radio-carpal joint disorder and contracture, arm hypotrophia, arm atrophia, leg hypotrophia and total atrophia decreased after treatments. Conclusion: This study showed the efficacy of pharmacopuncture combined with complex rehabilitation for the treatment of neuromotor system diseases.

Conventional disinfectants and disinfection method are expensive, hazardous and often require long periods of exposure. Recently, there is growing interest in complex disinfection process as a disinfection technique in medical instruments such as endoscope, hand piece bur to improve the disinfection efficiency and conveniency. The aim of this study was to evaluate the performance of a new complex process for the purpose of disinfection of Escherichia coli in water. Three single process (electrolysis, UV and ultrasonic process) was combined dual and triple disinfection process. The order of disinfection performance for E. coli in dual process lie in: Electrolysis + UV > Electrolysis + Ultrasonic > UV + Ultrasonic process. Disinfection efficiency of E. coli and degradation of N, N-Dimethyl-4-nitrosoaniline (RNO, indicating material of OH radical formation) of dual process was higher than that of the triple process (Electrolysis + UV + Ultrasonic process). In electrolysis + UV process, disinfection tendency was well agreed with RNO degradation tendency.

Cysteine-silver complexes were prepared and investigated the antimicrobial activity on rubber mat manufactured with waste rubber. We are exposed to harmful bacteria and fungi all the time. We manufactured antimicrobial mat to be imposed to mats that it can prevent generation of bacteria and microorganisms, and restrict their reproduction. Infection of medical devices causes significant morbidity and mortality. For aim of this study, we measured the antimicrobial mat manufactured with cysteine-Ag complex by CCD, FT-IR and NMR. The effect of mole ratio of cysteine-Ag complex on antimicrobial activity to bacteria and fungi is investigated. Reduction rate is evaluated using the Quinn method. Antimicrobial activity of complex on mole ratio 1:4 was effectively inhibited. The complexes had a better antibacterial activity than antifungal activity on rubber mat.

Objectives : Through the study on the complex efficacy of Sosihotang(小柴胡湯), it would be expected to comprehend the concept of diseases and syndromes that will be treated and principle of composing formula. Methods : It has been done to compare and analyse provisions of Shanghanlun related with Sosihotang(小柴胡湯). Results : Sosihotang(小柴胡湯) is fit to treat symptoms based on diseases having half exterior and half interior, deficiency and excess syndromes, because it is well-composed to focus on Soyangbyeong(少陽病) and Sosihotang(小柴胡湯) syndrome caused from lose of homeostasis in human body. Conclusions : Sosihotang(小柴胡湯) is one of the multipurpose formula that can be used to treat the syndromes and diseases of exterior and interionr(表裏), cold and heat(寒熱), deficiency and excess(虛實). Therefore it is necessary to research and develop the formula with the type.

Pulmonary arterial hypertension (PAH) is often difficult to diagnose and challenging to treat. Untreated, it is characterized by a progressive increase in pulmonary vascular resistance leading to right ventricular failure and death. The past decade has seen remarkable improvements in therapy, driven largely by the conduct of randomized controlled trials. Still, the selection of most appropriate therapy is complex, and requires familiarity with the disease process, evidence from treatment trials, complicated drug delivery systems, dosing regimens, side effects, and complications. We tried to provide evidence-based treatment recommendations for physicians involved in the care of these complex patients. Due to the complexity of the diagnostic evaluation required, and the treatment options available, it is strongly recommended that consideration be given to referral of patients with PAH to a specialized center.

Rheumatoid arthritis (RA) is o chronic inflammatory disease of joints with proliferation of synovial epithelial tissue. Therapeutic approach of the RA consists of pharmacological and surgical interventions. Synovectomy is indicated in patients with progressive inflammatory signs and symptoms intractable to medical treatment including local intracavitary steroid injection. Recently, local injection of radionuclides which emit high energy beta rays are labeled with chemical compounds such as $^{90}Y,\;^{165}Dy-ferric$ hydroxide macroaggregate and have been introduced as an alternative therapeutic modality to surgical synovectomy. Holmium-166 is one of beta emitter and Ho-166-chitosan complex was developed for radiation synovectomy. Preclinical trial is on-going at our hospital using Ho-166-chitosan. The procedure and methods of preclinical trial are discussed.

Powder injection molding(PIM) is widely used for many parts in the field of automotives, electronics and medical industries, due to the capability of net shaping for complex 3-D geometry. Powder injection mold design for the dental scaler tip, a component of medical appliance, was presented. In comparison with conventional machining process, powder injection molding has many advantages, specially in price and dimensional stability, for molding dental scaler tip which has complex geometry. Both product design and mold design for dental scaler tip were presented. A PIM feedstock was made of stainless series(17-4PH, 316L, 440C) powder and a wax based binder. The 'rapid mold' concept was applied to manufacture the various forms and materials of dental scaler tip including vibration characteristics.
