We provide a traceable ciphertext-policy attribute based encryption (CP-ABE) construction for monotone access structures (MAS) based on composite order bilinear groups, which is secure adaptively under the standard model. We construct this scheme by making use of an "encoding technique" which represents the MAS by their minimal sets to encrypt the messages. To date, for all traceable CP-ABE schemes, their encryption costs grow linearly with the MAS size, the decryption costs grow linearly with the qualified rows in the span programs. However, in our traceable CP-ABE, the ciphertext is linear with the minimal sets, and decryption needs merely three bilinear pairing computations and two exponent computations, which improves the efficiency extremely and has constant decryption. At last, the detailed security and traceability proof is given.

This guidance is an updated version of the irritable bowel syndrome (IBS) guidelines based on evidence-based medicine. IBS is a common chronic gastrointestinal syndrome that occurs in approximately 10% of the population and causes chronic abdominal pain as well as bowel habit changes, such as stool frequency or consistency. The final diagnosis of IBS is based on the exclusion of organic diseases that would explain the symptoms and the absence of endoscopic abnormalities. IBS can reduce the quality of life and cause a major disease burden, such as repeated examinations and continuous drug use, by mistaking organic diseases including malignancy. The major changes are as follows: 1) when to perform a colonoscopy under the impression of IBS; 2) effect of a low-fermentable oligosaccharides, disaccharides, monosaccharides, and polyol diet; 3) impact of probiotics in IBS; and 4) role of antibiotics in IBS. The Korean Society of Neurogastroenterology and Motility recently updated these guidelines to support physicians for qualified medical services and reduce the socioeconomic burden of IBS.

Technological innovations can be protected by patents, and patent applications are filed in various patent offices around the world including the United States Patent and Trademark Office (USPTO). Recently, the U.S. exportation of artificial intelligence and internet of things patents in the form of foreign sales of articles embodying U.S. patents and international technology licenses has grown substantially. However, due to the U.S. Supreme Court's Lexmark decision reconfirming an international patent exhaustion doctrine, the asian or korean importers importing such U.S. goods embodying U.S. patents do not have to worry about patent infringement liability, even when they try to resell the patented goods to the third parties. KCAB can play a substantial role in resolving such patent disputes due to qualified expert arbitrators and the International Rules of KCAB which ensure impartiality and independence of the arbitrators.

Oral appliances therapy is becoming increasingly recognized as a successful treatment for snoring and obstructive sleep apnea(OSA). Compared with continuous positive airway pressure(CPAP), the gold standard therapy for OSA, oral appliance therapy are less efficacious for severe OSA but are more acceptable and tolerable for patients, which in turn, may lead to a comparable level of therapeutic effectiveness. Nevertheless, the various side effects of oral appliance therapy, such as, increased salivation or dryness, pain or discomfort in the teeth or gums, occlusal discomfort in the morning, temporomandibular disorders, dental and occlusal changes may cause discontinuation of treatment or changes in treatment plan. Therefore, oral appliance therapy should be provided by a qualified dentist who can evaluate oral tissues, occlusion, and temporomandibular joints, and prevent and manage the possible side effects.

Prognostics and health management (PHM) is recently converging throughout the industry, one of the trending issue is to detect abnormal conditions at decanter centrifuge during water treatment facilities. Wastewater treatment operation produces corrosive gas which results failures on attached sensors. This scenario causes frequent sensor replacement and requires highly qualified manager's visual inspection while replacing important parts such as bearings and screws. In this paper, we propose anomaly detection by measuring the vibration of the decanter centrifuge based on the video camera images. Measuring the vibration of the screw decanter by applying the optical flow technique, the amount of movement change of the corresponding pixel is measured and fed into the LST M model. As a result, it is possible to detect the normal/warning/dangerous state based on LSTM classification. In the future work, we aim to gather more abnormal data in order to increase the further accuracy so that it can be utilized in the field of industry.

The article notes that one of the reasons for the crisis in education was the sharp discrepancy between the emerging new forms and content and the model of macro-management that has developed over the decades. The level of management of the educational system did not emerge as a specific activity characterized by its own mechanisms and processes, just as qualified carriers of this activity - professionals - managers - did not appear. At the same time, there is practically no theoretical and methodological model of the macrolevel of education management, that is, management of the educational system as an integral structure.

Fewer patients undergo pediatric lung transplantation (PLT) than adult lung transplantation. Size mismatch is the key factor that limits the availability of potential donors. Every candidate for PLT is in a different scenario in terms of age, height and weight, size of structures, indications for PLT, the concomitant presence of a cardiac anomaly, and other individual-specific factors; thus, a thorough understanding of pediatric patients' medical problems is essential. Living-donor lobar lung transplantation (LDLLT) has only been performed once in Korea to date. However, since each step in the LDLLT is a well-established procedure, including intrapericardial lobectomy, lung procurement, and lobar lung transplantation, qualified surgeons and lung transplantation teams are competent to perform LDLLT in clinically necessary situations.

Veterinary education is the foundation of veterinary services in the country. Starting from the service sector in the army, veterinary education and practice in Thailand have been standardized and progressed toward international veterinary standards. The 6-year Doctor of Veterinary Medicine core curriculum is deployed to develop the curriculum for each Veterinary Education Establishment (VEE). The challenges for veterinary education and practices reflect the country's expectations of veterinary services. With regional and global collaboration, the VEEs have been developing tools and learning platforms for delivering qualified veterinary graduates that fit fast-growing society needs.

Objective: The purpose of this systematic review and meta-analysis was to investigate potential effects of HRT (hormone replacement therapy) on motor functions in postmenopausal women. Method: In this meta-analysis, 19 studies that examined changes in motor functions between postmenopausal women with and without HRT intervention were qualified. We additionally conducted moderator variable analyses including: (1) motor function type, (2) hormone type, and (3) duration of HRT intervention. Results: The random effects model showed no significant overall effects (SMD = 0.199; SE = 0.115; 95% CI = -0.026~0.425; Z = 1.730; p = 0.084; I² = 93.258%). Additional three moderator variable analyses revealed no significant effect sizes indicating that specific HRT protocols did not improve different motor functions in postmenopausal women. Conclusion: These meta-analytic findings suggest that HRT had no positive effects on motor functions in postmenopausal women.
