The importance of Structural Health Monitoring (SHM) in the industry is increasing due to various loads, such as earthquakes and wind, having a significant impact on the performance of structures and equipment. Estimating responses is crucial for the effective health management of these assets. However, using numerous sensors in facilities and equipment for response estimation causes economic challenges. Additionally, it could require a response from locations where sensors cannot be attached. Digital twin technology has garnered significant attention in the industry to address these challenges. This paper constructs a digital twin system utilizing the Long Short-Term Memory (LSTM) model to estimate responses in a pipe system under simultaneous seismic load and arbitrary loads. The performance of the data-driven digital twin system was verified through a comparative analysis of experimental data, demonstrating that the constructed digital twin system successfully estimated the responses.

Purpose: The purpose of this paper is to provide information about rehabilitation options for subjective tinnitus. While there are several clear treatment options for objective tinnitus, there is no clear treatment option for subjective tinnitus. Although many researchers and clinicians have suggested various rehabilitation options for subjective tinnitus, it is still difficult to determine which rehabilitation options are proper because types of subjective tinnitus vary across patients. Methods: While there are several clear treatment options for objective tinnitus, there is no clear treatment option for subjective tinnitus. Although many researchers and clinicians have suggested various rehabilitation options for subjective tinnitus, it is still difficult to determine which rehabilitation options are proper because types of subjective tinnitus vary across patients. Results: Researchers have suggested several rehabilitation options to reduce effects of tinnitus such as depression, stress, and disturbed sleep. Rehabilitation options for subjective tinnitus are counseling, sound therapy, tinnitus retraining therapy, neuromonics, biofeedback, cognitive behavioral treatment, and mindfulness therapy. Conclusion: This paper will provide useful information about various rehabilitation options for subjective tinnitus which can be applicable in clinics.

This paper reviewed the tinnitus associations in the U.S.A., Australia, United Kingdom, European Federation, and one tinnitus research initiative. The American Tinnitus Association (ATA), which was the first tinnitus association in the world established in 1971, has pursued to find a cure for tinnitus and funded vital tinnitus research. The ATA provides informational brochures. The British Tinnitus Association (BTA) aims to support tinnitus patients and to seek effective management of tinnitus. The BTA offers several education programs for clinicians dealing with tinnitus patients in addition to fund tinnitus research. Moreover, the BTA offers direct counsel to tinnitus patients on the phone, and publishes twenty one of informal leaflets. In Australia, two of four tinnitus associations were reviewed; The Australian Tinnitus Association (ATA, Australia TA) and Tinnitus South Association (Tinnitus SA). The Australia TA provides the information about tinnitus, supports tinnitus patients, publishes a tinnitus magazine, and informs people tinnitus treatments through their home page. The Tinnitus SA was established by support of government of South Australia on the purpose of informing people about tinnitus. The Tinnitus SA provides an on-line tinnitus questionnaire, and off-line counselling for patients. The European Federation of Tinnitus Association (EUTI) was recently formed by tinnitus associations from 18 countries within Europe in order to cooperate to help patients. The Tinnitus Research Initiative (TRI) has been established by some research institutes in several countries in order to perform cooperative research and share the results. However, in Korea, there is no tinnitus association except one formed by Korean veteran, which has no information about tinnitus. Considering increasing number of tinnitus patients in Korea, the tinnitus association for helping patients and leading research should be formed in the near future.
