In cleft palate patient, characteristic of speech disorder is the resonance disorder result from velopharyngeal incompetence. Clinically VPI caused by congenital factor as congenital palatal incompetence, submucosal cleft palate, and caused by acquired factor as CNS damage, tumor, palatal palsy. The clinicians more concerned about the speech disorders after cleft palate surgery rather than language pathologist. The resonance disorder devided for hypernasality, hyponasality and nasal emission, but as a rule, hypernasality is typical phenomenon of the resonance disorder. Traditionally clinicians and language pathologists evaluated four-stage or five-stage of hypernasality by subjective assessment. Although language pathologist is well-trained, results of the language level should be different. In late 1980s, Kay Elemetrics Corp. developed nasometer that objective nasalance identified with well-trained language pathologist and originate from nasometer Tonar I and II were developed by Fletcher. Therefore objective nasalance test was possible, the nasometer used in hospital, collage and speech clinic both and home and abroad. Standardization of the cleft palate speech assessment must be settled without delay because of different character result in different language and different assessment results by dialect in same language. In our study, we provide the data base for the standardization of cleft palate speech assessment which through report of objective assessment method, speech therapy effects and problems result in interdisciplinary teamwork by nasometer use in treatment of cleft palate patient.

In this work, an improved architecture of two-dimensional digital filter(2D DF) is suggested, and then the filter is simulated by C, VHDL language and related layouts are designed by Berkeley CAD tools. The 2D DF consists of one-dimensional digital filters and delay lines. For one-dimensional digital filter(1D DF) case, once filter coefficients are represented by canonical signed digit formats, multiplications are exected by hardwired-shifting methods. The related bit numbers are handled to prevent picture quality degradation and pipelined adder architectures are adopted in each tap and output stage to speed up the filter. For delay line case, line-sharing DRAM is adopted to improve power dissipation and speed. The filter layout is designed by semi/full custom methods considering regularity and speed improvement, and normal operation is confirmed by simulation.

In this paper, message time delay is considered in the SCCP(Signalling Connection Control Part) of the CCITT common channel signalling system No.7. In this simulation, the protocol of the SCCP is programmed using C language and this program is considered on condiion of only connectionless mode and class 0. This simulation reveals bottleneck point depending on message processing capability in the SCCP, so this simulation shows the low limit of the SCCP's processing capability. We show that bottleneck point is at 2000[ messages/sec ] on model A and at 3500[ message/sec ] in model C.

Recently, increased accessibility to the Internet makes it possible to access to Internet-connected devices easily. For this reason, anyone can reach and command any device that is connected to the network. But these teleoperation systems have several problems like the network time delay, data loss and development cost of an application for communication with each other. The network time delay phenomenon is the most important in teleoperation system, which disturbs a real time control. The loss data also causes some users not to send correct commands to device or not to receive correct information from devices. To develop an application to communicate between user and device, it needs a comp..

In this paper load redistribution algorithm to allow fault-tolerance by redistributing the workload of n failure nodes to the remaining good nodes in distributed systems are investigated. To evaluate the efficiency of the algorithms a simulation model of algorithms is developed using SLAM II simulation language. The job arrival rate service rate failure and repair rate of nodes and communication delay time due to load migraion are used as parameters. The result of the simulation shows that the job arrival rate failure and repair rate of nodes do not affected on the relative efficiency of algorithms. If the communication delay time is greater than average job processing time algorithm B is better. Otherwise algorithm C is superior to the others.

Due to the asymptotic property, deadbeat control can hardly applied to the continuous time system control. But some delay element method can deal such a problem. Except delay element method, well-known digital deadbeat control can br used with the aid of som smoothing elements. In this paper, and order smoothing element is used for the smoothing of the digital deadbeat controller. And this element is argumented to the plant, and so control problem is to control digitally the argumented system. We simulated this control system using Matlab language and finally apply this algorithm to the rotary inverted pendulum system.

In recent years, artificial intelligence (AI) services have become one of the most essential parts to extend human capabilities in various fields such as face recognition for security, weather prediction, and so on. Various learning algorithms for existing AI services are utilized, such as classification, regression, and deep learning, to increase accuracy and efficiency for humans. Nonetheless, these services face many challenges such as fake news spread on social media, stock selection, and volatility delay in stock prediction systems and inaccurate movie-based recommendation systems. In this paper, various algorithms are presented to mitigate these issues in different systems and services. Convolutional neural network algorithms are used for detecting fake news in Korean language with a Word-Embedded model. It is based on k-clique and data mining and increased accuracy in personalized recommendation-based services stock selection and volatility delay in stock prediction. Other algorithms like multi-level fusion processing address problems of lack of real-time database.

Cerebral creatine deficiency syndrome (CCDS) is a disorder where a defect is present in transport of creatine in the brain. Creatine plays an essential role in the energy metabolism of the brain. This is a genetic disorder, autosomal recessive or X linked, characterized by intellectual disability, speech and language delay, epilepsy, hypotonia, etc. Until recently very few number of cases have been reported. Here we report a case of 1.5-year-old boy who had epilepsy (epileptic spasm and generalized tonic clonic seizure), intellectual disability, microcephaly, hypotonia and speech delay. His magnetic resonance imaging of brain showed cortical atrophy and electroencephalography showed burst suppression pattern. The diagnosis was confirmed by clinical exome sequencing which showed novel mutation of SLC6A8+ in exon 9, suggestive of X linked recessive CCDS. The patient was then treated with glycine, L-arginine and creatine monohydrate with multiple antiepileptic drugs.

Transportation energy saving is a national concern because all national petroleum energy is imported. A number of intersections are operating as semi-protected intersections, which have left-turn signal but not exclusive left-turn lanes, because of limited roadways in urban areas. Since the traffic signal methods for the intersections having left-turn signal/lanes cannot be applied to the semi-protected intersection, it is needed to develop a new technique. The purpose of this study was to develop a traffic signal timing method at semi-protected intersections for energy saving and to computerize the method for the practical use. A probability model which could estimate left-turn utilization factors of through traffic during green signal was developed based on field studies. Employing the factors, macro-models to estimate vehicular average delay and proportions of vehicles stopped at the semiprotected intersections were developed. The calculated values of the delay model agreed well with the simulated values of a simulation model using SLAM Ⅱ, a simulation language. Using the two models and the idling fuel consumption rate and the excess fuel consumption per stop-go speed change of vehicles. a traffic signal timing method at semi-protected intersections for energy saving was developed and computerized. The method can be used for other measures of effectiveness such as minimum delay, minimum stop ratio, etc.
