A retrospective study of 132 cases of natural Escherichia coli infection in preweaning piglets with diarrhea submitted to the Department of Veterinary Pathology in Seoul National University from 1995 to 1996 was performed to determine the biochemical characteristics and antibiotics susceptibility. Most field isolates were lysine decarboxylase-positive (99.2%), phenylalanine decarboxylase-negative (100%), and fermented sorbitol (91.7%). Antibiotic susceptibilities will be determined by agar diffusion method. A large percentage of isolates were resistant to many antibiotics in common usage. Most isolates were susceptible to colistin (98.8%), gentamycin (64.3%), amikacin (100%), and ceftiour sodium (64.2%), whereas most isolates were notably resistant to ampicillin (86.9%), neomycin (66.7%), streptomycin (84.5%), tetracycline (98.8%), penicillin (98.8%), and amoxacillin (58.3%).

Purpose: Illness intrusiveness (illness induced lifestyle disruption) by symptoms was investigated in 439 patients with rheumatoid arthritis. Method: The cross-sectional and retrospective survey design was used. Fatigue, disability, pain, and depression were considered as symptoms of rheumatoid arthritis. Result: Patients were reported to perceive more illness intrusiveness than other chronic disease patients such as end stage renal disease, bipolar disorder, and peritoneal dialysis patients. They were especially intrusive into work, health, and active recreation domains. Stepwise regression analysis identified four variables counting for 26% of illness intrusiveness variances: fatigue, disability, marital status, and depression. All of the symptoms except pain were found to significantly predict illness intrusiveness. Fatigue explained 16% of illness intrusiveness variances. Conclusion: Fatigue and depression usually overlooked by health professionals must be carefully assessed and managed to reduce perceived illness for rheumatoid arthritis patients.

Introduction: 585 nm Pulsed dye laser (PDL) laryngeal surgery is based on the photodynamic characteristics of selective photothermolysis and photoangiolysis and recently considered to be the treatment for a variety of benign laryngeal disease. Objective: To review the indications and outcome of office-based 585nm PDL surgery and summarize new developments. Method: Retrospective study involving 402 patients was performed, The PDL surgery could be applied to various laryngeal diseases such as laryngeal papilloma, vocal fold dysplasia, laryngeal granuloma, vocal polyp, capillarectasia, scarred vocal fold and sulcus vocalis. Results : The physiologic properties of the vascular specificity of PDL provide many advantages and appear to be effective for laryngeal treatment. The PDL resulted in precise, selective coagulation of the microvasculature without damage to the surrounding tissue. Therefore PDL surgery is safe and effective for office-based treatment of benign laryngeal disease and for all patients regardless of their overall medical condition. Conclusion: PDL surgery provides potential benefits and advantage for treating common benign laryngeal disease.

This study was designed to assess the current status of infant feeding through an retrospective survey on feeding method. The survey was executed for 417 mothers bringing up a child below 24 months in Seoul and Kyunggi-Do province from September to October, 1993. Analysing a few influential environmental factors while assessing the level of knowledge today's mother have on infant feeding. Incidence of breast feeding was 27.8% of the interviewed mothers, which showed lower percentages than those of previous surveys. This research proved the major influencing factor generally depended on its mother rather than babies. Generally mothers knew the information of infant feeding, but their knowledge actually didn't work. The source of mothers' informations on the infant nutrition showed the grandmother, books and magazines, doctor were many by the order. among the reasons of resent formula and mixed feeding, lack of breast milk' was the commonest as 50.5% and the next reason was 'because of job' as 12.6%.

The zygoma is protruded on both sides of the midface and plays an important part in determining the impression of face. There are much different esthetic consideration of zygomatic prominence between the oriental and western. Because slight prominent zygoma is thought to be esthetic in the western, there has been done many augmentation therapy. But, in the oriental, prominent zygoma, especially in the female, is thought to be aggresive and manlike image, there has been done many zygoma reduction therapy. There are two methods to reduce the prominent zygoma, one is shaving method and the other is zygoma repositioning with ostectomy. The approach to zygoma and zygomatic arch without surgical morbidity is very difficult, so this problem has been difficult subject to oral & maxillofacial surgeon in a long period. We report the treatment case of facial asymmetry with the unilateral zygoma reduction & genioplasty using only intraoral approach with the retrospective study.

Reasonable and reliable assessment method is one of the most important issues in science education, Partial credits method is an effective tool for assessing students' science inquiry problem solving. The purposes of this study were to classify the Problem solving types based on the analysis of the thinking Process, and how much the related science concept and the science process skills were used in solving science inquiry problems, and to describe the possibility and rationality of the assessment method that gives partial credit 128 high school seniors were selected and their answers were analyzed to identify science concepts they used to solve each problem, and the result was used as the criterion in the scientific concept test development. Also, to study the science inquiry problem solving type, 152 high school seniors were selected, and protocols were made from audio-taped data of their problem solving process through a think-aloud method and retrospective interviews. In order to get a raw data needed in statistical comparison of reliability, discrimination and the difficulty of the test and the production of the regression equation that determines the ratio of partial credit, 640 students were selected and they were given a science inquiry problem test, a science process skills test, and a scientific concept test. Research result suggested it is more reasonable and reliable to switch to the assessment method that applies partial credit to different problem solving types based on the analysis of the thinking process in problem solving process, instead of the dichotomous credit method.

Retrospective review of 26 patients undergoing open lung biopsy at the Yonsei University during 10 years period was conducted to evaluate open lung biopsy for DILD. From January 1980 to August 1990, open lung biopsy was performed in 26 patients through a limited thoracotomy incision[a limited anterior or a posterolateral thoracotomy]. Open lung biopsy was indicated for diffuse interstitial pulmonary diseases undiagnosed by indirect clinical and radiological diagnostic methods. The types of incision were limited anterior[11] and limited posterolateral[15]. Preoperative evaluation of the lung disease included sputum culture[26], sputum cytology [19], bronchoscopy[9] and TBLB[7]. In 23 patients the histologic appearances after open lung biopsy were sufficiently specific histologic pictures to confirm diagnosis. The results of the biopsies changed usual therapeutic plan in 17 patients among them. The complications were resp. insufficiency[3], pulmonary ed6ma[3], sepsis[2], and others[3] in 6 patients. Diagnosis from the open lung biopsy was included respiratory pneumonia[7], fibrosis[7], infection[5], malignancy[2], others[5]. 4 patients died of respiratory insufficiency. The causes of the other three death were not due to direct result of the biopsy itself. Open lung biopsy in the patient with a diffuse infiltrative lung disease is an one of the accurate diagnostic method and frequently leads to change of the therapeutic plans. So we conclude that open lung biopsy remains our diagnostic method of choice in diffuse infiltrative lung disease undetermined etiology.
