  • In this paper, we introduce automatic meter reading system for tap water. The system is composed of automatic meter, router using RF and CDMA network, and data server. This system will easily extend to fire detect, gas, and electric charge meter system. In addition, this system will be used to monitoring a water leak and human which live in solitude. Proposed system is installed at Gimhae-City and Gijang-gun. As a result of the automatic meter reading system for tap water, The leak of water and complain of user is decreased. But The building cost is still an obstacle to expand into entire city.

  • Over a period from July 1984 to June 1985, 39 cases of open heart surgery were done under cardiopulmonary bypass. There were 23 male and 16 female patients, ranging in age from 18 months to 58 years. Thirty cases were valvular disease. The most common of congenital heart disease is VSD. Among the 9 cases of acquired valvular diseae,1 MAP, 5 MVR, 2 MVR+TAP, and 1 MVR+AVR were done. There were 1 operative death[11%] which was done MVR+TAP. Operative mortality in 30 congenital heart disease was 7%; 1 death [5%] in 22 acyanotic and 1[13%] in 8 cyanotic cases. Finally, overall mortality for 39 cases was 8%; 7% for congenital heart disease and 11% for acquired heart disease.

  • In this paper, in order to implement the IDWT(inverse discrete wavelet transform) with relatively low complexity, we propose a VLSI architecture for odd-tap linear-phase IDWT filters. By considering the symmetric property of the linear phase filter, the input is added to the one located at symmetrical position of the filter before filtering. Then. we rearrange the delay line of the filter in a U-shaped fashion. requiring no global interconnection between the components. The proposed architecture for the IDWT filter consists of delay units. operator units, adder units. and postprocessor unit. Since each units are configured regularly and interconnected locally. the proposed architecture can accommodate arbitrary linear phase IDWTs by simply adding/removing the corresponding units. The M -level IDWT can be implemented by interconnecting the proposed architecture in a cascaded or semi-recursive form. It is expected that the proposed architecture for the IDWT can be effectively employed in the related area including MPEG-4, since the proposed architecture is less complex than the conventional architectures.

  • This study is to help fine some factors of how the Initial food consumption ability affects articulation production and intelligibility in children at aged 4-15 with cerebral palsy. According to the factor analysis of articulation production, here are some positive articulation productions; the ability of mumbling and swallowing food, biting and swallowing and liquid diet, the experience of food consumption therapy, the use of specific methods or tools for food consumption, the behavior-problem during a meal and the beginning of the neck control. Therefore, the study finds that the Initial food consumption ability in children with spastic cerebral palsy may affect articulation production and intelligibility.

  • There are generally two temperature control methods using ac voltage regulators - the phase control method and the on-off control method. The phase control method uses thyristor's angles of extinction for the output power regulation and the on-off control method uses the control of on and off times for the output power regulation. Both of methods have the problems that are the unbalance of the three phase and surge current caused system's destruction. The main object of this study proposes a solution of problems of surge currents and unbalance of three phase when thyristor voltage regulator is switching. To solve the problem, It is proposes that the solution of surge currents is using a tap transformer and an additional switch with adjustable resistance and applies zero crossing of switching voltage of two input line to power load. This method is discuss and verified by computer simulations and experiments.

  • A cDNA clone (GenBank accession no. CF924621) homologous to aluminum induced protein gene was isolated and characterized from Codonopsis lanceolata (ClAIP). The ClAIP is 906 nucleotides long and has an open reading frame of 711 bp with a deduced amino acid sequence of 236 residues. The ClAIP shows high homology to A. marina (84%), G. hirsutum(83%), V. radiata (83%), A. thaliana (80%), B. nap us (78%) and T. aestivum (68%). The deduced amino acid sequence of ClAIP also has homology to the N-terminal end of plant Asn synthetase. This region does not contain the active sites of the enzyme and the significance of this conservation is currently not clear. To investigate the expression of ClAIP against several heavy metal stresses, we treated the sliced tap root of C. lanceolata with various heavy metals. The expression of ClAIP was increased by 25 uM $Al_2$(SO$_3$)$_4$ in proportion to incubation time and also increased by 50 uM CdCl$_2$.

  • Synchronous wind-induced pressures, measured in wind-tunnel tests on model buildings instrumented with hundreds of pressure taps, are an invaluable resource for designing safe buildings efficiently. They enable a much more detailed, accurate representation of the forces and moments that drive engineering design than conventional tables and graphs do. However, the very large volumes of data that such tests typically generate pose a challenge to their widespread use in practice. This paper explains how a wavelet representation for the time series of pressure measurements acquired at each tap can be used to compress the data drastically while preserving those features that are most influential for design, and also how it enables incremental data transmission, adaptable to the accuracy needs of each particular application. The loss incurred in such compression is tunable and known. Compression rates as high as 90% induce distortions that are statistically indistinguishable from the intrinsic variability of wind-tunnel testing, which we gauge based on an unusually large collection of replicated tests done under the same wind-tunnel conditions.

  • Purpose - The international market provides a growth momentum for firms by allowing them to tap into a new market. Given information asymmetry between firms and financial analysts, firms' international growth can be perceived as a higher business prospect by analysts. This paper explores the possibility of analysts' over-emphasis on foreign income growth in predicting earnings. Research design, data, and methodology - We utilize a sample of U.S. firms to test the relationship between foreign income growth and analysts' forecast optimism. Our sample of publicly listed and traded U.S. firms between 1976 and 2016 consists of 6,120 firm-year observations. Results - Empirical analyses show that firms that show higher international growth in earnings are likely to face forecast inaccuracy by financial analysts. From the perspective of firms, their earnings are less than what analysts forecasted. Contrary to our prediction on the moderating effect of innovative capabilities, optimistic bias is not intensified - rather, it is reduced - when firms have higher innovative capabilities. Conclusions - Our results imply that while analysts favor firms with higher international growth, innovative capability on the international market places additional risks to firms' operation.

  • Experiments were carried out to develop of mutant strain from Pichia ciferrii ATCC 14091 and investigate the effect of sodium acetate on the production of tetraacetylphytosphingosine (TAPS). A high-TAPS producing mutant was simply selected by staining with sudan black B and colony shape after the treatment of UV and NTG. Sodium acetate enhanced the TAPS production.

  • Generally, material for radiator of automobile is composed of Al-alloy, but part of radiator material is still composed of Cu. Specially, Al-alloy replaces Cu and Cu-alloy as cooling and heating system material for light weight. Therefore, galvanic electronic cell is formed between Al-alloy and Cu for automobile radiator material, and Al-alloy corrosion is accelerated. So, in this study, galvanic corrosion test of Al-alloy coupling with Cu was carried out in distilled water, tap water, polluted environment and non-freezing solution. And thus corrosion potential and galvanic currrent density of Al-alloy coupling with Cu is investigated.
