        The aim of this article is to improve human health and that of companion animals by improving the diagnosis and control of parasitic diseases. This is achieved by research into parasites of veterinary significance including zoonoses and the use of comparative systems to increase our understanding of some human parasitic diseases. We should promotes learning and teaching through knowledge and operates a diagnostic unit that offers a service to pet owner for indigenous and exotic parasitic diseases of companion animals. We must diagnose and treat them early. Zoonotic parasites are very important because many of animal parasites are zoonoses and give pain and death to human. Parasites are divided Protozoa, Helminthes and Arthropods. There are many protozoa, about 65,000 species. Arthropods are the vector of another diseases, such as virus, bacteria, protozoa and nematodes. Helminthes are composed of Trematoda, Cestoda, Nematoda and Acanthocephala. The target of Veterinary Parasitology is to recognize the characteristics of these parasites and subsequently diagnose, treat and control them. This article is intended to familiarize you with the essential facts and concepts of companion animal parasitology. Emphasis is placed on fecal sample techniques (comparison of fecal examination techniques; frequently found artifacts in fecal smears; direct Smear; zinc sulfate flotation; etc.) We recommend that the study be done to more references on animal parasites.

      • 제2형 당뇨병 환자에서 우연히 발견된 기종성 방광염 1례

        박보민,김윤정,이영태,노정현,권수경,김동준,고경수,이병두,임경호,이순희,박정현 白中央醫療院 2005 仁濟醫學 Vol.26 No.1

        Emphysematous cystitis is an uncommon disease in which bacterias produce gas within the bladder wall and surrounding tissue. Patients with diabetes, neurogenic bladder and chronic urinary tract infection are predisposed to the disease. It is usually caused by E.coli and Klebsiella. Severity of illness ranges from an asymtomatic condition to life threatening cystitis. Succesful management depends on early diagnosis with correction of underlying causes, administration of appropriate antibiotics, establishment of adequate bladder drainage and surgical excision of involved tissue when required. We report a case of 52-year-old woman who did not compain of symtoms of cystitis but epigastric pain, nausea, and vomitting. Emphysematous cystitis was revealed on the abdominal X-ray series incidentally. CT scans of the pelvis showed mottled gas bubble within the bladder. After treatment, the symtoms subsided and plain abdominal film showed no evidence of gas shadow in the pelvic cavity.

      • Relationship between Meteorological Elements and Yield of Perilla in Yeosu Area

        Kwon,Byung-Sun,Park,Hee-Jin 한국자원식물학회 2003 Plant Resources Vol.6 No.3

        This study was conducted to investigate the relationship between yearly variations of climatic elements and yearly variations of productivity in perilla. In addition, correlation coefficients among yield and yield components were estimated. The data of yield and yield components were investigated for 10 years from 1991 to 2000. The meteorological data gathered at the Yeosu Weather Station for the same period were used to find out the relationships between climatic elements and productivity. Yearly variation of the amount of precipitation in September was large with coefficients of variation(c. v.) of 11.1%, but the coefficient of variance(c. v.) in July and August were relative small with 1.8, 2.1%, respectively. Number of cluster per hill and weight of 1,000 grains were greatly with c. v. of 76.1, 79.3%, respectively, but the coefficients of variance(c. v.) of plant height and seed yield were more less with 9.58, 10.60%, respectively. Correlation coefficients between precipitation of September and seed yield were positively significant correlation at the level of 5.1%, respectively, but the duration of sunshine in September and seed yield were negatively significant at the level of 5.1%, respectively. Correlation coefficients of these, the plant height, number of branches per plant, cluster length, number of cluster per hill, weight of 1,000 grains and seed yield were positively significant at the level of 5.1% respectively.

      • 보리잎의 色素, 蛋白質含量 및 光系Ⅱ 活性에 미치는 Sulfite의 影響

        權炳奎,鄭華淑,朴基元 慶北大學校 師範大學 1985 敎育硏究誌 Vol.27 No.-

        Sulfur dioxide, a major atmospheric pollutant, influences to photosynthesis and causes some damages such as chlorosis, necrosis etc. When SO_2 enters into leaf tissue through the stomata, it produces H^+, HSO_3^- and SO_3^-2 as it is dissolved in the water of cells. On the basis of a report that sulfite (SO_3^-2) serves as the most toxic material to SO_2 phytotoxicity, we treated sodium sulfite at the indicated concentrations and treatment time to barley leaves. Then the leaf disks were illuminated at 30,000 lux and placed in darkness. This study was carried out to investigate the effects of sulfite on pigments, protein content, and photosystem Ⅱ activity in barley leaves. With sulfite treatement of barley leaf disks, pigment and protein content were decreased in light but not in darkness. The rate of DCIP photoreduction was inhibited in light-dependence of sulfite. It was inhibited to 78% with sulfite (10mM) treatment for 1 hour.

        Kwon,Byung-Sun,Shin,Jeong-Sik,Shin,Dong-Young,Hyun,Kyu-Hwan,Park,Hee-Jin,Sin,Jong-Sup,Seong-Kyu 한국자원식물학회 2003 Plant Resources Vol.6 No.2

        To find out the optimum fertilizer level for high yielding variety, Velox, experiment was conducted with 15 compositions of fertilizer levels at the experiment field of forage crop in Sunchon National University from Mar. 2000 to Aug. 2000. The effects of nitrogen fertilizer on plant growth were significant but increasing rate of application in potassium and phosphate fertilizers above 6 kg/a had negligible effects on plant growth. The optimum nitrogen application level of fertilizers turned out to be 16-6-6 kg/l0a of N-P2O5-K5O. Content of crude protein was highest and that of crude fiber such as NDF, ADF, cellulose and lignin were lowest at this rate of fertilizer application. Furthermore, IVDMD was high and dry matter yield were highest at the optimum raterate

        This study was conducted to investigate the relationships between yearly variations of meteorological elements and yearly variations of productivity in rice. In addition, correlation coefficients among yield and yield components were used to find out the relationships between meteorological elements and productivity. Yearly variation of the mean air temperature in May was large with coefficients of variation(C.V.) of 25.0%, but the variation of the duration of sunshine in May were relative small. No. of panicles per hill and 1,000 grains wt. of brown rice were great with C.V. of 21.1, 19.7%, respectively, brown rice yield show more or less C.V. of 5.5% and milled rice show still less variation. Correlation coefficients between temperatures in period of cultivation from May and yield were positive correlations. Correlation Coefficients between precipitation in period of cultivation from Sep. to Oct. and yield are positive correlations. Correlation coefficients amount the panicle length, no. of panicles, no. of spikelets, ratio of ripened grains, 1,000 grains wt. of brown rice, milled rice yield, brown rice yield and milled rice yield were positively significant at the level of 1 %, respectively.

      • Cadmium과 Di-(2-ethylhexyl) Phthalate에 의한 고환 독성 : 아연과 Apoptosis의 역할 The Role of Zinc and Apoptosis

        권민,최병선,박언섭,홍연표,박정덕 중앙대학교 의과대학 의과학연구소 2003 中央醫大誌 Vol.28 No.1

        Cadmium (Cd) and di-(2-ethylhexyl) phthalate are used widely and distributed ubiquitously in the environment, which are well-known reproductive toxicants. DEHP and/or Cd causes the apoptosis, degeneration of spermatogenic cells, and massive necrosis, resulting in testicular atrophy. Zinc is an essential metal in spermatogenesis, the zinc concentration in testis is changed in DEHP- or Cd-treated animals. However, the role of zinc or apoptosis in testicular toxicity by DEHP or Cd has not been understood well. In this study, Sprague-Dawley male rats were given DEHP (2 g/kg, 5 ml corn-oil, PO) or Cd (CdCl₂2 mg/kg, 4 ml saline, sc) for 1, 2, 7 and 14 days. Control rats were given vehicle corresponding to each group. At day 1, 2, 7, and 14 after administration of DEHP or Cd, the morphological findings including apoptosis in testes were observed under the light microscope, and the zinc concentrations in testes were determined by atomic absorption spectrometry with flame method. Fas and FasL mRNA in testes were analyzed by RT-PCR method at 12 hours, 1, 7, 14 days after adminstration of DEHP or Cd. Absolute and relative testicular weight were lower in DEHP- or Cd-treated rats than control. DEHP or Cd produced morphological changes in testes, including apoptosis, degeneration, necrosis and massive loss of spermatogenic cells, resulting in testicular atrophy. The zinc concentration in testes was not different at day 1 after administration of DEHP, but was decreased at later times. Testicular zinc was lower at day 1, 2 in Cd-treated rats than control, but was higher at 7, 14 days after Cd administration. The levels of Fas and FasL mRNA were highly expressed in testes after administration of DEHP or Cd. These results suggest that the change of zinc level in testes might be a secondary effect of DEHP- or Cd-induced testicular toxicity, and Fas signal system might be play an important role in pocessing of apoptosis in testes by DEHP or Cd.

      • 사용자 스키마와 규칙을 이용한 웹 정보 추출

        박병권 동아대학교 정보기술연구소 2006 情報技術硏究所論文誌 Vol.14 No.1

        To query the vast amount of web pages which are available in the Internet, it is necessary to extract the encoded information in the web pages for converting it into structured data (e.g. relational data for SQL) or semistructured data (e.g. XML data for XQuery). In this paper, we propose a new web information extraction system, PIES, to convert web information into XML documents. PIES is based on a user-specified schema and HTML tag pattern descriptions. The web information is extracted by the pattern descriptions and validated by the schema. We designed a new language to describe extraction rules, and a new regular expression language to describe HTML tag patterns. We implemented PIES and applied it to the US patent web site to demonstrate its feasibility. It successfully extracted more than thousands of US patent data and converted them into XML documents.

        상관논리 활동을 통한 중학생들의 상관논리 유형 변화

        박종윤,김지영,남정희,이상권,최병순 한국과학교육학회 2002 한국과학교육학회지 Vol.22 No.4

        본 연구에서는 우리나라 중학교 학생들의 상관논리형성정도와 그 유형을 알아보고, 상관논리 활동을 통하여 학생들의 상관논리에 어떤 변화가 있는가를 알아보고자 하였다. 이를 위하여 중학교 2학년 학생 111명을 실험집단으로, 55명을 통제집단으로 선정하였다. 사전 검사에서는 두 집단 모두 상관논리의 형성률이 낮았으며, 집단간 차이는 없었다. 사후 검사에서는 실험집단의 상관논리 형성률이 유의미하게 증가하였으며, 통제집단의 경우는 사전 검사와 차이가 없는 것으로 나타나 상관논리 활동이 상관논리 형성에 도움이 되는 것을 알 수 있었다. 그러나 사후 검사에서도 실험집단의 정답률이 객관식 문항에서는 27%, 서술형 문항에서는 6% 정도로 나타나 상관논리가 완전히 형성된 학생들의 비율은 상당히 낮은 것으로 나타났다. The main purpose of this study is to investigate whether the correlational reasoning activities could improve middle school students' correlational reasoning abilities. The subjects were 8th grade students, and the correlational reasoning activities of the CASE(cognitive acceleration through science education) program was intervened to the experimental group(m=111) during science class while usual science instruction was given to the control group(m-55). The correlational reasoning test was administered before and after the intervention. The pre-test results showed that most of subjects performed poorly in correlation problems and no significant differences were found between the two groups. In the post-test, the experimental group showed enhanced performance while the control group did not. Therefore it can be concluded that CASE program activities help the students to improve correlational reasoning ability. However, the proportions of students gave correct response were not so high: 27% for the multiple-choice item and about 6% for the essay-type items.
