  • This study describes a fetal heart rate(FHR) estimation algorithm using phonogram. Using a phonogram amplifier, various fetal heart sounds are collected in a university hospital. The FHR estimation algorithms consists of a lowpass filter, decimation, envelop detection, pitch detection, and post-processing. The post-processing is the FHR decision procedure using all informations of fetal heart rates. Using the algorithm and other parameters of fetal heart sound, a fetal monitoring software was developed. This can display the original signals, the FFT spectra, FHR and its trajectory. Even though the fetal phonogram amplifier detects the fetal heart sounds well, the sound quality is not so good as the ultrasonography. In case of very week fetal heart sound, autocorrelation of it showed clear periodicity. But two main peaks in one period is an obstacle in pitch detection and peaks are not so vivid. The proposed FHR estimation algorithm showed very accurate and stable results. Since the developed software displays multiple parameters in real time and has convenient functions, it will be useful for the phonogram-style fetal monitoring device.

  • During delivery, fetal death rate is about 1%. Since fetal death or infection have been continuously occurred, low cost fetal monitoring techniques are required. This study proposes an electronic stethoscope system for fetal phonogram by developing an amplifier to detect fetal movement and heart sound from abdomen of the pregnant woman. Using the electronic stethoscope, it is possible to listen or record the fetal sound and to analyze or store the digitized signal. Through the performance test using the developed system with 30 pregnant women in university hospital, it was found that the developed amplifier showed low noise, high performance. The system can detect heart sound and periods of heartbeats of a 22-week fetus.

  • Objective : Every language has twofold aspects in meaning of characters such as 'lead' means guide as a verb and 'lead' means one of metals. Chinese character has several meanings because it is phonogram, even if those are exactly same in shapes. we have concern how different meaning of the character 'Si(死)' is in traditional medical classics. Method : we try to find out the meaning of 'Si' excluding meaning of 'Si', 'death' in "Huangdineijing". Result : 'Si' means 'death' primary and means 'serious disease to death', 'losing consciousness just like death' and so on. Conclusion : Someone who have concern traditional medical classics have to give attentions that characters in classics could get different meanings in same character.

  • Objective : Each terminology has twofold meaning. Chinese character has several meanings because it is phonogram. Even if exactly same in shapes but the meaning is different. We should be more careful about meaning of the character Fu(胕) in Huangdineijing. Method : We try to find out the meaning of fu excluding meaning of fu(胕), edema(胕腫) in Huangdineijing. Result : Fu means fermented food, edema, sticking, skin, top side of the foot and so on. Conclusion : Someone who have concern traditional medical classics have to give attentions that characters in classics could get different meanings in same character.

  • One main complexity of the copula constructions concerns a mismatch between morphology and syntactic constituency: the copula seems to form a morphological unit with the immediately preceding element, whereas in terms of syntax the copula appears to take this as its syntactic complement. In capturing such mismatches, we show that the copula is treated as an independent verb at the level of tectogrammatical structure (or syntax tree), whereas as a bound morpheme at the level of phonogram-matical structure (or domain tree), in terms of Dowty 1992 (or Reape 1994). This paper, adopting the notion of DOMAIN in HPSG, shows that copula constructions are a subtype of compacting-constructions. These constructions compact the domain value of the copula and that of its preceding element together into one domain unit, eventually making it inert to syntactic phenomena such as scrambling, deletion and pro-form substitution. This construction-based approach provides a clean analysis for the formation of the copula construction and related phenomena.

  • Genetic status of Acnnthamoebc sap. were tested on the basis of random amplified polymorphic DNA (RAPD) marker analysis. Four previously established Accnthcmoebn species, 4 Korean isolates of Acnnthamoeba sp., and one American isolate of Acanthcmoebc sp. were analyzed by RAPD-PCR using an arbitrary decamer primers. Amplification products were fractionated by agarose gel electrophoresis and slainrd by ethidium bromide . Eighteen primers produced DNA amplification profiles revealing clear differences among 4 species. Nine of them also produced DNA amplification profiles which included some isolate-specific amplification products. On the basis of amplified fragments by 18 primers, the pairwise similarity indices between A. culbensoni and other species (i.e. A. hntchetti, A. trinngularis, A. polyphaga) were 0.300, 0.308, and 0.313, respectively. Similarity index between A. hctchetti and A. triansulcris was 0.833. The mean similarity index among the 3 Korean isolates (YM-2, -3, -4) was 0.959 and 0.832 among them and 2 other species (A. hatchetti and A. triongulnris). The mean similarity index among YM-5 and other Korean isolates (YM-2, -3, -4) was 0.237. However, the similarity index between YM-5 and A. culbeksoni was 0.857, which suggests that YM-5 is genetically more similar to A. culbertsoni than other Korean isolates. Phonogram reconstructed by UPGMA method revealed that there are two groups: one group consists of A. hctchetti, A. tlonsulcns, and 3 Korean isolates (YM-2, -3, -4) , and the other group consists of A. cuLbensoni. A. polwphosc, HOV, and YM-5.

  • Public Performance in Copyright Law is a wider concept, which people generally think. It includes the presentation of a work to the public by acting, musical playing, singing, narrating as well as even the act of mechanical playing phonogram and cinematographic work. Article 29 in Korean Copyright Act is the restriction of an author's public performance right. It shall be permissible to perform publicly or broadcast a work already made public for nonprofit purposes and without charging any fees to audience, spectators, or third parties, provided that the performers concerned are not paid any remuneration for such performances. Commercial phonograms or cinematographic works may be played back for the public, if no fee is charged to the audience or spectators, except in cases as set forth by Presidential Decree. In recent year, public performance in libraries became a major issue of the Copyright Law. It is a claim that watching cinematographic works in libraries is one of the act that should apply public performance right, thus to use commercial cinematographic works before six months, which was published, need permission to copyright owners. But this claim is unfair because it can make impossible normal library service. Thus there is a need to revise the Copyright Law to understand the difference between act of viewing and public performance in libraries.

  • In case of PAS test, the air is sometimes leaked although the mask is tightly attached to the face, which is not reliable on the measured values. Therefore, this study aimed to assist the clinical practice suggesting the test method of PAS without air leakage. In the healthy subjects with 12 males and 12 females over 19 years old, three types of tests were performed on the voicing efficiency among the protocol of PAS Model 6600. They are; first, to attach the mask tightly to the face holding the handle of PAS with the subject's two hands (Method 1); second, to attach the mask tightly to the face holding the handle of PAS with the subject's one hand and pushing the body of PAS strongly with the other hand (Method 2); and third, to attach the mask tightly to the face pushing the upper part of the mask by the tester when the subject attached the mask to his or her face holding the handle of PAS with two hands (Method 3). Upon the study analyses, the mean negative pressure, the mean phonogram, subglottic air pressure, and voicing efficiency were shown to be statistically significantly different during PAS test in males depending on the methods. (p<.05) In case of females, only the target airflow rate showed significant difference depending on the methods during PAS test. (p<.001) In conclusion, Method 2 enhanced the noise level and strength while Method 1 was likely to leak the air more compared to the other two methods in males. In case of females, Method 1 showed significant leakage of the air flow. Not to allow the air flow leakage without affecting the outcome of PAS test, it will be the most useful for the tester to push the mask to the subject's face tightly (Method 3).

  • This study was carried out to evaluate the suitability of simple sequence repeat (SSR) markers for varietal identification and genetic diversity in 28 commercial tomato varieties. The relationship between marker genotypes and 28 varieties was analyzed. Of the 219 pairs of SSR primers screened against ten tomato varieties, 18 pairs were highly polymorphic with polymorphism information content (PIC) ranging from 0.467 to 0.800. Among the polymorphic loci, two to nine SSR alleles were detected for each locus with an average of 3.3 alleles per locus. Genetic distances were estimated according to Jaccard's methods based on the probability that the amplified fragment from one genotype would be present in another genotype. These varieties were categorized into cherry and classic fruit groups corresponding to varietal types and genetic distance of cluster ranging from 0.35 to 0.97. The phonogram discriminated all varieties by marker genotypes. The SSR markers proved to be useful variety identification and genetic resource analysis of tomato.
