Fungi belonging to the Paecilomyces spp. have recently been used as food and herbal medicines in Korea and are greatly popular as commercially available powdered supplement or dried fruiting body. Despite this acceptance and its use, little is known of the genes related to its reactive agents. Presently, We have constructed an olig-d(T) primed directional cDNA library from the silkworm Dongchunghacho, an entomopathogenic fungus, of which species is belonging to Paecilomyces spp. based on the previous identification of ITS1 and ITS2 at the molecular level and collected from Jocheon Miryang, Korea. To isolate and screen genes in the fungus, 626 expressed sequence tags(ESTs) were generated by a partial sequencing from the cDNA library. cDNA encoding the glyceraldehyde-3-phosphate dehydrogenase(Pt-GAPDH) of Paecilomyces tenuipes- Jocheon was cloned from the above cDNA library. The complete cDNA sequence of Pt-GAPDH is comprised of 1,014bp encoding 338 amino acid residues. The deduced protein sequence of Pt-GAPDH showed higher homology with Beauberia bassiana-GAPDH(93% amino acid identity). Hydropathy analysis revealed that Pt-GAPDH protein is hydrophilic. The major three amino acids in its composition of amino acid residues were alanine(11.54%), valine(9.47%) and glycine(8.88%). The Pt-GAPDH gene of Paecilomyces tenuipes entomopathogenic fungus consisted of three exons and two introns coding for 338 amino acid residues, and the genomic DNA length of the gene spans 1302bp. The accession number of the gene in GenBank are GU997099 for Pt-GAPDH cDNA and GU997102 for Pt-GAPDH genomic DNA. More investigation works including gene expression, immunological analysis etc. will be carried continuously without hesitation after this presentation.

Objective: The aim of this study was to investigate the clinical significance of myocardial injuries in patients with nontraumatic intracranial hemorrhage by identifying the occurrence of myocardial injury and defining its correlation with subsequent cardiovascular events. Subjects and methods: One hundred twenty-four patients with nontraumatic intracraninal hemorrhage presented to the emergency department within six hours from onset of symptoms were enrolled. Brain CT, serial electrocardiography, and echocardiography were done at the emergency center. Blood samples for troponin I and creatine kinase(CK)-MB were drawn immediately and eight hours after admission, Troponin I and CK-MB were measured using a chemiluminescent immunoassay, respectively. Results: Electrocardiographic and echocardiography abnormalities were found in 65 cases(52.4%) and 21 cases(17%), respectively. Serum troponin I and creative kinase-MB were increased in 35 cases (28.2%) and in 58 cases(46.8%), respectively. Abnormal findings of echocardiography and ECG, as well as elevated levels of serum troponin I and creative kinase-MB, were associated with an increased risk of cardiovascular event and survival. Logistic regression analysis revealed that an abnormal echcocardiographic finding and elevation of serum troponin I were factors associated with the occurrence an adverse cardiovascular event and that electrocardiographic abnormalities and initial mental status were factors associated with poor prognosis. Conclusion: This study reveals that actual myocardial injury develops in a significant proportion of patients with nontraumatic intracranial hemorrhage and that the development of the myocardial injury is associated with an adverse cardiovascular event that occurs during admission.

In myotonic dystrophy(MD), a characteristic myopathy is accompanied by abnormalities of other systems, including the brain. The pathogenesis of MD has not been clearly explained. Sometimes white matter lesion was noted on brain MRI, but its causative roles and association with intellectual impairment in MD was not clea yet. We report a case of myotonic dystrophy with intellectual impairment and temporal white matter lesions.

In this thesis, the graphic signal for communication is presented in the WINDOW using `Visual-Basic'. All signals of PCM encoding/decoding and modulation/demodulation are processed in the same picture. Especially, error control schemes which are parity check, longiudinal redundancy check, cyclic redundancy check, are described for more reliable communication.

저자들은 다발성 뇌 농양을 동반한 치명적인 파종성 S. apiospermum 감염이 발생한 간 이식 환자를 경험하였다. 본 증례의 환자는 voriconazole로 치료하는 호전경과를 보이다가 진균성 뇌 동맥류 파열로 사망하였다. S. apio-spermum은 비교적 드문 진균으로 병리학적으로 Aspergillus spp.와 매우 유사하고 amphotericin B에 내성을 나타내므로 진단과 치료가 적절하게 이루어지지 못할 가능성이 많고 면역 기능 저하 환자에서 혈행성 전파를 통한 파종성 감염이 용이하게 발생하므로 높은 사망률을 나타낸다. 이식 환자를 비롯한 면역 기능 저하 환자에서 진균감염이 의심될 때 S. apiospermum과 같은 드문 진균에 의한 감염증도 감별진단에 포함해야 하겠다. Sedosporium apiospermum is a saprophytic fungus commonly found in soil and polluted water. This organism is known as a cause of mycetoma, which may occur in immunocompetent hosts following trauma. However, in immunocompromised patients, S. apiospermum can also cause life-threatening invasive disease, including central nervous system infection or disseminated infection. We report a fatal case of disseminated S. apiospermum infection in a 46-year-old woman after liver transplantation. Eight days postoperatively, she developed pneumonia, followed by altered mentality in the 15 days. A head CT demonstrated multiple brain abscesses. Sputum and stereotactic-aspirated brain abscess culture yielded S. apiospermum. Despite treatment with voriconazole, the patient died of intracranial hemorrhage.

요골신경의 분지인 후골간 신경손상은 주로 요골골두 손상이나 골절에 의해 나타나며, 지방종, 결절종, 점액낭염, 섬유종 또는 류마티스양 활막염 등의 비 외상성 압박에 의해서도 발생할 수 있으나 특별한 원인 없이 자발적으로 발생하는 후골간 신경손상은 비교적 드물다. 저자들은 수면 후 발생한 좌 상지 근력저하를 주소로 내원하여 시행한 신경학적 검사와 전기 생리학적 검사에서 특별한 원인 없이 자발적으로 발생한 후골간 신경손상을 경험하였기에 문헌고찰과 함께 보고하는 바이다. Posterior interosseous nerve, deep muscular branch of radial nerve, can be compressed by tumor, ganglion, fibroma, bursitis, or rheumatoid synovitis. But, spontaneous posterior interosseous nerve neuropathy is relatively rare. We report a case of spontaneous, non-traumatic paralysis of the posterior interosseous nerve.

To invent environmentally friendly materials for packaging of agricultural produce, morphological and mechanical properly changes after daylight exposure and soil deposit for LDPE films composed of different incorporation substances have been investigated. Silver coated ceramic, zinc oxide, fine particle of ferrofluid and pine needle's extract were the incorporated substances. The pine needle's film degrades fast in soil while the silver coated ceramic's film shows daylight decay more on the morphological view. The mechanical strength keeps almost same. But turndown of elongation is explicit on the pine needle's film and silver coated ceramic's film.

본 연구에서는 과학교육에서 수행평가의 올바른 사용과 정착을 위하여 과학 수행평가문항의 선정과 제작을 위한 평가준거를 개발하였다. 이를 위하여 과학과 평가목표 및 수행평가에 대한 이론적 논의를 통해 평가준거의 대범주로 평가 목표의 충실도(Fidelity), 수행평가의 특징과 구성 요소에 대한 만족도(Satisfaction), 문항의 내용 타당도(Content Validity), 학습자에 대한 내용의 적합도 및 공정성(Suitability & Fairness), 문항의 신뢰도와 객관도(Reliability & Objectivity), 사용상의 편의성 및 실용성(Usability)의 6가지 범주를 개발하였고, 각 대범주별 하위항목을 선정하여, 총 25개의 하위 항목을 가진 평가준거표를 개발하였다. 그리고 개발된 평가준거표의 타당도는 과학교육 연구자 5명의 안면타당도로 보았고, 신뢰도는 3가지 종류의 과학 수행평가문항을 과학교육 전문가 2명과 초등예비교사 6명이 평가하교, 그 결과를 Kendall계수를 통한 평가자간 합치도로 검증하였다. 그 결과 합치도는 통계적으로 유의한 수준으로 나타났다. 이상의 과정을 통하여 최종적인 평가준거표를 완성하여 제시하였다. We have developed of a criterion that would help to select and develop performance assessments in science education. There are six categories of a criterion: Fidelity, satisfaction, content validity, fairness & suitability, reliability & objectivity, and usability. There are the total of 25 sub-categories under the six categories. Five science educators evaluated the validity of the criterion. For reliability of the criterion, Kendall's tau-b was used. Eight science educators and elementary teachers evaluated three performance assessment tasks for the correspondence of the criterion. This study also discuss the implications of this criterions as well.
