  • To establish the differential diagnosis and treatment method in bovine ovarian cysts, specially ovarian cysts with corpus luteum, serum progesterone concentration and ulrasonography for measuring the cyclic area, thickness of cystic wall and echogenicity of corpus luteum were investigated in cystic ovaries from slaughtered cows. The incidence rates of ovarian cysts were follicular cyst 69.2% and luteal cyst 30.8%. The incidence rates of 8 various types of ovarian cysts were as follows; 2Ba 32.3%, 2Aa 25.8% and 2Bb 14.5%, respectively. The thickness of cystic wall were 2Bb 3.93mm, 2Ab 3.70mm and 1Aa 1.93mm and the serum progesterone concentrations were above 1.0ng/$m\ell$ in 2Ab, 2Bb and IAa, respectively. The cystic area of ovarian cysts with corpus luteum was 288.30mm2, but ovarian cysts without corpus luteum 542.30$\textrm{mm}^2$, and the thickness of cystic wall 2.12mm and 2.40mm, respectively. The serum progesterone concentration was 1.91ng/$m\ell$ in ovarian cysts with corpus luteum and 1.20ng/$m\ell$ ovarian cysts without corpus luteum. There was not the correlations between thickness of cystic wall and serum progesterone concentration in ovarian cysts with corpus luteum, whereas, was the correlations in ovarian cysts without corpus. These results indicated that PGF2$\alpha$ analogues can be choice for treating the ovarian cysts with corpus luteum because serum progesterone concentrations were above 1.0ng/$m\ell$ in ovarian cysts with corpus luteum. In conclusion, it is suggest that ultrasonography is useful diagnostic tool for diagnosing and choicing of treatment remedy in cystic ovaries of bovine.

  • Objectives: This study was designed to investigate the effect of Bombycis corpus on reproductive dysfunction caused by aging. Methods: The experimental group was divided into three groups: a control group consisting of 8-week-old male ICR mice without any treatment, An aging-elicited group (AE group) consisting of 50-week-old ICR male mice without any treatment, and a Bombycis corpus treatment group (BC group) consisting of 50-week-old ICR male mice with treatment Bombycis corpus extract (0.78 g/kg/day) for 6 months. After 6 months, histochemistry and immunohistochemistry of the testis were performed to investigate the effects of Bombycis corpus on the reproductive dysfunction caused by aging. Results: In the first step, Bombycis corpus increased spermatogenesis and distribution of sertoli cells in the seminiferous tubule, increased BrdU positive reaction in the spermatogonium at the basal part of the seminiferous tubule, and decreased the apoptosis of Sertoli cells in the seminiferous tubule. In addition, Bombycis corpus increased AR positive in Sertoli cells and $17{\beta}-HSD$ positive in leydig cells. Finally, Bombycis corpus decreased 8-OHdG positivite reaction in the spermatids of the seminiferous lumen, caspase-3 positivity in leydig cells, and HDAC1 positivite reaction in sertoli cells. Conclusions: These results suggest that Bombycis corpus increases spermatogenesis, decreases apoptosis of leydig cells and Sertoli cells, increases the production and action of testosterone in the testis, and inhibits DNA damages and DNA transcripts decrease in the testis, Thereby improving reproductive dysfunction caused by aging.

  • To investigate the effect of Bombycis Corpus on male osteoporosis, we performed Dual Energy X-Ray Absorptiometry(DEXA) and histochemical methods. The animals were used ICR-based male mice of 8 weeks and 50 weeks, respectively. ICR male mice at 8 weeks were used in the control group, and ICR male mice at 50 weeks were used in aging group and Bombycis Corpus group(BC group). In the aging group, 0.5 ml of distilled water was administered once a day for 6 months. In BC group, Bombycis Corpus(0.78g/kg) was dissolved in distilled water for 6 months once a day. As a result, Bombycis Corpus decreased bone loss, increased bone density by reducing the loss of bone matrix in the femur due to aging, and increased osteoblast - induced osteopontin(OPN) and osteocalcin(OPC) positivite reaction. In addition, administration of Bombycis Corpus decreased Reaction of activation of nuclear factor kappa B ligand(RANKL) positive reaction, increased osteoprotegerin(OPG) positive reaction, and decreased matrix metalloproteinase-3(MMP-3) and 8-hydroxy-2'-deoxyguanosine(8-OHdG) positivite reaction. Taken together, Bombycis Corpus increases the activity of osteoblasts, inhibits osteoclast function, promotes osteoblast function, inhibits bone tissue degradation, and inhibits bone loss due to oxidative stress. It was observed that Bombycis Corpus reduced bone loss and increased bone density caused by aging to improve male osteoporosis. Therefore, Bombycis Corpus may be used as a preventive and therapeutic agent for male osteoporosis.

  • Ultrasonography was used to measure the corpus luteum area for determining the relationships between corpus luteum size and milk progesterone concentration during the estrous cycle in 16 dairy cows. Cows were classified retrospectively into cows that had corpus luteum with(n=P) and without(n=7) cavity. Ultrasound examination and collection of milk samples for progesterone assay were performed with 2 day intervals from Days 0 to 12, and then daily from Day 14 to the day of the next ovulation. The means for corpus luteum area and for milk progesterone concentration during the estrous cycle were not significantly different between cows that had corpus luteum with and without cavity. The correlation coefficients between corpus luteum area and milk progesterone concentration during luteal development (Days 2 to 8) were 0.71(p<0.0001) and 0.74(p<0.0001) for corpus luteum with and without cavity, respectively, during luteal regression(Days -6 to 0 relative to the next ovulation) 0.73(p<0.0001) and 0.76(p<0.0001), respectively. The correlation coefficients combined fur both stages of estrous cycle and both luteal statuses were 0.70(p<0.0001). These results indicate that corpus luteum area is significantly correlated to milk progesterone concentration, and ultrasonographic assessment of the corpus luteum is a reliable method fur estimating peripheral progesterone concentrations during the estrous cycle in cows.

  • In a mobile environment, communication takes place via SMS text messages. Vocabularies used in SMS texts can be expected to use vocabularies of different classes from those used in general Korean literary style sentence. For example, in the case of a typical literary style, the sentence is correctly initiated or terminated and the sentence is well constructed, while SMS text corpus often replaces the component with an omission and a brief representation. To analyze these vocabulary usage characteristics, the existing colloquial style corpus and the literary style corpus are used. The experiment compares and analyzes the vocabulary use characteristics of the colloquial corpus SMS text corpus and the Naver Sentiment Movie Corpus, and the written Korean written corpus. For the comparison and analysis of vocabulary for each corpus, the part of speech tag adjective (VA) was used as a standard, and a distinctive collexeme analysis method was used to measure collostructural strength. As a result, it was confirmed that adjectives related to emotional expression such as'good-','sorry-', and'joy-' were preferred in the SMS text corpus, while adjectives related to evaluation expressions were preferred in the Naver Sentiment Movie Corpus. The word embedding was used to automatically construct a sentiment lexicon based on the extracted adjectives with high collostructural strength, and a total of 343,603 sentiment representations were automatically built.

  • The purpose of this paper is to find out some major characteristics of intermediate-advanced Korean learners' English by corpus- linguistically analyzing their essays in comparison with native speakers'. We construct a corpus of CBT TOEFL essays by Korean learners, NNS1 (94076 words in 402 texts), and its sub-corpus, NNS2 (14291 words in 45 texts), and then a corpus of model essays written or meticulously edited by native speakers, NS (14833 words in 35 texts). We compare NNS1 and NNS2 with NS, and with some other corpora, in terms of high-frequency words, and show that Korean learners' writings have more features of informal writing than those of formal writing, which is in accord with the reports in Granger (1998) that EFL writings by European advanced learners are characterized by informality.

  • To clarify the activating effects of Scolopendrae corpus on immunological function, its effect on primary and secondary antibodies production in mice of various ages was investigated. Scolopendrae corpus increased the number of both antibody producing cells(anti-IgM and anti-IgG producing plaque forming cells, PFC) and phagocytic activity of peritoneal macrophage. Futhermore, these phenomena were significantly increased with aging in mice. Scolopendrae corpus also increased natural killer cell activity concerning to cancer immunology. These results suggest that Scolopendrae corpus markedly increases the reduced activity in the elderly and activates the immune response in senescence mice.

  • This paper aims to investigate how word order interacts with cliticization in Sakizaya, a Formosan language. This paper looks into nominative and genitive case markers from a corpus-based approach. The data are collected from an online dictionary of Sakizaya, and they are classified into two word orders: nominative case marker preceding genitive case marker and vice versa. The data are also divided into three categories, according to the demarcation of the case markers, which include right, left, or no demarcation. The corpus includes 700 sentences in the construction of predicate + noun phrase + noun phrase. The results suggest that the two case markers tend to be parsed into the preceding word and show right demarcation. The results also reveal that there are type difference and distance effect of the case markers on the cliticization. Nominative case markers show more right demarcation than genitive case markers do in the corpus. Also, the closer the case markers are to the predicate, the more possible the case markers undergo cliticization.

  • This paper makes a quantitative analysis of the diachronic evolution of ancient Chinese vocabulary by constructing and counting a large-scale rough annotated corpus. The texts from Si Ku Quan Shu (a collection of Chinese ancient books) are automatically segmented to obtain ancient Chinese vocabulary with time information, which is used to the statistics on word frequency, standardized type/token ratio and proportion of monosyllabic words and dissyllabic words. Through data analysis, this study has the following four findings. Firstly, the high-frequency words in ancient Chinese are stable to a certain extent. Secondly, there is no obvious dissyllabic trend in ancient Chinese vocabulary. Moreover, the Northern and Southern Dynasties (420-589 AD) and Yuan Dynasty (1271-1368 AD) are probably the two periods with the most abundant vocabulary in ancient Chinese. Finally, the unique words with high frequency in each dynasty are mainly official titles with real power. These findings break away from qualitative methods used in traditional researches on Chinese language history and instead uses quantitative methods to draw macroscopic conclusions from large-scale corpus.
