  • Error control performance of the (16, 7) minimum-bandwidth binary error cotrol line code (MB-ECLC) according to decoding algorithms is analyzed and compared in this paper. As a result , when retransmission is not allowed or meaningless. to reduce performance degradation ad computational burden. the modified soft decision decoding algorithm using the structure of (16,7) MB-ELEC is proposed. The error cotnrol capability of this modified algorithm is far better than that of a hard decision decoding algorithm, and almost same as that of a full soft decision decoding algorithm. In additino, the number of comparisons for the modified algorithm is decreased more than 5 times as compared with a full soft decision decoding algorithm.

  • The purpose of this study was to review the limb apraxia. It includes the evaluation and neurophysiological aspects for limb apraxia. Limb apraxia comprised a wide spectrum of higher-order motor disorders that results from acquired brain disease affecting the performance of skilled and/or learned movements with the forelimbs and is a common sequela of left brain damage that consists of a deficit in performing gestures to verbal command or to imitation. There are two forms in limb apraxia; ideational apraxia and ideomotor apraxia. A assessment of limb apraxia typically includes pantomiming and imitation of transitive, intransitive, and meaningless gestures. Limb apraxia has been attributed to damage confined to the cerebral cortex, cortico-cortical connecting pathways, and basal ganglia.

  • Some children with Cleft Palate have shown a speech disorders after repaired surgical operation. A diagnostic evaluation of speech in children with cleft palates is important in preventing speech disorders. However, standard speech evaluation form for children with cleft palates has not yet developed in Korea. The purpose of this study is to make the standard speech evaluation form for children with cleft palates. Thirty control children group and ten children with cleft palate participated in this experiment. The test words are composed of meaningless two syllabic words containing the three different types of korean stop consonants,

  • Steganography, which is popular as an image processing technology, is the art of using digital images to hide a secret message in such a way that its existence can only be discovered by the sender and the intended receiver. This technique has the advantage of concealing secret information in a cover medium without drawing attention to it, unlike cryptography, which tries to convert data into something messy or meaningless. In this paper, we propose two efficient least significant bit (LSB)-based steganography techniques for designing an image-based steganography system on chip using hardware description language (HDL). The proposed techniques manipulate the LSB plane of the cover image to embed text inside it. The output of these algorithms is a stego-image which has the same quality as that of the original image. We also implement the proposed techniques using the Altera field programmable gate array (FPGA) and Quartus II design software.

  • Meaningless in such a rapidly grown society to have a conventional and tedious understanding and interpretation of the public only in terms of the relationship of others. This study, therefore, investigates and developed the notion and the importance of the public that has been formed and developed with the urban growth and that has disappeared through modernization. The arument will be focused on how to revitalize the public in the contemporary cities through a right interpretation of the public in the contemporary. The ultimate purpose of the thesis is to propose a design strategy by which the new public sphere will be reconstructed within the contemporary office space.

  • Bae and W. Park [3] proved the Hyers-Ulam stability of bi-homomorphisms and bi-derivations in $C^*$-ternary algebras. It is easy to show that the definitions of bi-homomorphisms and bi-derivations, given in [3], are meaningless. So we correct the definitions of bi-homomorphisms and bi-derivations. Under the conditions in the main theorems, we can show that the related mappings must be zero. In this paper, we correct the statements and the proofs of the results, and prove the corrected theorems.

  • In this paper, we propose a coding method to improve compression efficiency for MR image. This can be achieved by combining coding and segmentation scheme which removes noisy background region, which is meaningless for diagnosis, in MR image. The wavelet coder encodes only diagnostically significant foreground regions refering to segmentation map. Our proposed algorithm provides about 15% of bitrate reduction when compared with the same coder which is not combined with segmentation scheme. And the proposed scheme shows better reconstructed image Qualify than JPEG at the same compression ratio.

  • The purpose of this study is to find out the architectural device for two places to be perceived as having distinct characteristics from each other. A residence of Yi Dynasty is selected as the object appropriate for this purpose and analyzed accordingly. The result of the analysis can be presented on two demensionis one is that of the concrete form and the other is that of the abstract meaning generated by the form. It is meaningless to employ the form of the architecture of the past in today's architecture. The language of the architecture of the past must be reinterpreted into that of tody. This means understanding and expressing the meaning of the architecture of the past, using the form and materials available today. Without limiting its scope to figuring out "the architectural device for giving destinction" on the formal demension. this study tries to clarify the meaning generated by the form, on which its significance can be said to lie.

  • In a Doppler weather radar, high resolution windspeed profile measurements are needed to provide the reliable detection of hazardous weather conditions. For this purpose, the pulse pair method is generally considered to be the most efficient estimator, However, this estimator has some bias errors due to asymmetric spectra and may yield meaningless results in the case of a multimodal return spectrum. Although the poly-pulse pair method can reduce the bias errors of skewed weather spectra, the modes of spectrum may provide more reliable information than the statistical mean for the case of a multimodal or seriously skewed spectrum. Therefore, the idea of relatively simple mode estimator for a weather radar is developed in this paper, Performance simulations show promising results in the detection of hazardous weather conditions.

  • The articulation disorders associated with velopharyngeal insufficiency (VPI) in cleft palate patients are interested to clinicians particularly. The purpose of this study was to investigate mainly the oropharyngeal air pressure and overall air flow in cleft palate patients. The pressure-measuring catheter was positioned at the midportion of the oropharyngeal cavity with a facial mask. Test words were composed of 9 meaningless polysyllabic words and 17 meaningful words. Aerophone II and Nasometer II were used to measure peak air pressure, mean air pressure, maximum flow rate, volume, phonatory flow rate, nasalance. The data shows that airflow of the cleft palate patient group were higher than those of the control group. Intraoral air pressure of the cleft palate patient group was lower than those of the control group. The first vowel formant and first Bandwidths of the cleft palate patient group were higher than those of the control group.
