In this paper, we implement the signboard voice guidance service for visually impaired person using virtual beacon. The new location to provide a location-based service can be added easily by using virtual beacons, which are locating by Wi-fi, GPS, and so on, instead of physical beacons, which are locating by physical devices. We provide the voice service for guiding information of the captured signboard for the visually impaired when he arrived at the location registered through the virtual beacon.

The voice recognition technology is to recognize the voice of an user and execute the command. Recently, the voice recognition is evolving to the artificial intelligence voice recognition by adding the scheme of the natural language processing. The AI voice recognition is exploited to control the IoT devices or provide the information, such as the news or the wether. The University Information which is one of fields serviced by the information provider is mainly presented on the web. However, since too much information are presented on the web, it is difficult for an user to find efficiently the specific information which the user want to know. In this paper, we design and implement the university guidance system to recognize the user voice searching the information and provide the result using the voice. To do this, we classify the university data and design the lambda function to provide the data.

The purpose of this study was to examine guardian's attitudes toward behavior guidance techniques used in pediatric dentistry. In this study, 117 guardians participated and the several behavior guidance techniques being used during actual pediatric dental treatment were explained to the guardians prior to writing a questionnaire. The behavior guidance techniques explained were: tell-show-do, voice control, protective stabilization by device, protective stabilization by staff, nitrous oxide sedation, sedation, and general anesthesia. For analysis, 106 completed survey forms were selected. Tell-show-do was rated as the most acceptable technique, followed (in order of decreasing acceptance) by: voice control; protective stabilization by staff; nitrous oxide sedation; protective stabilization by device; sedation; general anesthesia. Acceptance of each behavior guidance technique was not related to guardian age, gender, patient age, patient gender, patient dental experience, type of visit, and position of doctor. Within the limit of this study, the communicative guidance techniques (tell-show-do, voice control) were more acceptable than advanced behavior guidance techniques (protective stabilization, sedation, general anesthesia). The acceptability of general anesthesia was the lowest. The results of this survey may contribute to maintain optimal dentist - guardians communication in pediatric dentistry.

The mutational falsetto is failure to change from the higher pitched voice of preadolescence to the lower pitched voice of adolescence and adulthood. The one of characteristic findings is contraction of suprahyoid muscles. The large majority of young men with inappropriately high voice have excellent voice therapy prognosis. We have experienced one case of mutational falsetto treated with botulinum toxin injection on suprahyoid muscles. His suprahyoid muscles are contracted markedly simultaneously with each phonation. fundamental frequency$(F_0)$ of his vowel phonation was 332Hz. Extensive voice therapy including manual compression of thyroid notch was ineffective. Forty units of Botox$^{\circledR}$ was injected under the EMG-guidance(20U bilaterally). At seven days post-injection, his voice changed lower than before and at 40 days after procedure, his $F_0$ was 126Hz.

As artificial intelligence develops, AI chatbot systems are actively taking place. For example, in public institutions, the use of chatbots is expanding to work assistance and professional knowledge services in civil complaints and administration, and private companies are using chatbots for interactive customer response services. In this study, we propose a scenario-based AI voice chatbot system to reduce museum operating costs and provide interactive guidance services to visitors. The implemented voice chatbot system consists of a watcher object that detects the user's voice by monitoring a specific directory in real-time, and an event handler object that outputs AI's response voice by performing inference by model sequentially when a voice file is created. And Including a function to prevent duplication using thread and a deque, GPU operations are not duplicated during inference in a single GPU environment.

Objectives : To compare the objective differences in voice quality and voice problems between clergies and normal male control group. Materials and Methods : The sustained vowel sound of 46 clergies and 40 normal persons were analyzed, using a videostroboscopy and acoustic analyzer. Together with these analyses, a questionnaire associated with current and past voice problems was handed over to the patients. Results : The most common symptom in subjective group was the voice fatigue. Stroboscopic findings in subjective group were as following 23 cases(50%) of pachydermia, 17 cases(37%) of phase difference, 12 cases(25%) of anterior-posterior contracture, 6 cases(13%) of vocal polyp and 3 cases(7%) of vocal nodule. The mean maximal phonation time in clergies was 17.8 seconds and in control group was 19 seconds. litter, pitch perturbation quotient and shimmer were significantly increased in subjective group than in control group(p<0.05), but there were no significant differences between two groups in fundamental frequency, vFo, amplitude perturbation quotient and noise to harmonic ratio. Conclusion : In the clergies using loud and forceful voice, vocal polyp and functional voice disorder findings were frequently noted in stroboscopic examination. litter and shimmer, reflecting the roughness of voice, were increased in acoustic analysis. Therefore, clergies, classified into untrained professional voice users, need professional career guidance and counseling.

In the era of the fourth industrial revolution, safety of disasters is being emphasized above all else, and electric fires are most frequent during disasters, and human and property damage is very serious. In this paper, we propose a study that can determine the efficiency of evacuation and non-evacuation guidance due to the large difference in casualties depending on the traffic line in the case of fire. Evacuation guidance was assumed to be a situation in which adequate evacuation routes were guided by a recorded voice or a trained staff, and non-evacuation guidance was assumed to be a situation without anything. Evacuation simulations were carried out using a evacuation simulation tool called PATHFINDER and SIMULEX for the analysis of the efficiency of evacuation and non-evacuation guidance. As a result, the evacuation time was similar, but in the case of non-evacuation guidance, it was not guided to the safe zone, which could cause serious damage.
