Purpose: The purpose of this study is to evaluate the clinical features that necessitate a temporary stoma for the treatment of colonoscopic perforations. Methods: Between January 2000 and July 2006, 30 patients were treated for colonoscopic perforation. Based on the perforation sites, we classified these patients into the following groups: proximal colon, sigmoid colon, and rectum; we then reviewed clinical data, including the time to operation and management. Results: Seventeen patients had a perforation during the diagnostic colonoscopy. Of these patients, 14 patients had sigmoid colon perforation. Six underwent an operation within 10 hours after perforation. Of these six, four were managed by primary repair or resection with anastomosis, one sigmoid colon cancer patient by anterior resection, and one rectal cancer patient by low anterior resection with diverting ileostomy. Eight patients underwent more than 12 hours after perforation. Of these eight, three were managed by resection with anastomosis and diverting ileostomy and five by resection with end colostomy. Thirteen patients had a perforation during the therapeutic colonoscopy. Of these patients, 10 patients had a proximal colon perforation. Of these 10, 3 without fever or peritonitis symptom were managed by conservative management, 6 by primary repair or resection with anastomosis, and 1 transverse colon cancer patient by right hemicolectomy. Three patients had sigmoid colon perforation. Of these three, one was managed by primary repair, one by resection with anastomosis, and one sigmoid colon cancer patient by anterior resection. Conclusions: The mechanism of perforation, the site of the perforation, and the time to operation are associated with intraperitoneal contamination and have an influence on surgical treatment.

Functional Analysis of the Stress-Inducible Soybean Calmodulin Isoform-4 (GmCaM-4) Promoter in Transgenic Tobacco Plants

박형철,Man Lyang Kim,Yun Hwan Kang,Jae Cheol Jeong,정미선,Wonkyun Choi,이상열,Moo Je Cho,김민철,정우식,윤대진 한국분자세포생물학회 2009 Molecules and cells Vol.27 No.4

The transcription of soybean (Glycine max) calmodulin isoform-4 (GmCaM-4) is dramatically induced within 0.5 h of exposure to pathogen or NaCl. Core cis-acting elements that regulate the expression of the GmCaM-4 gene in response to pathogen and salt stress were previously identified, between -1,207 and -1,128 bp, and between -858 and -728 bp, in the GmCaM-4 promoter. Here, we characterized the properties of the DNA-binding complexes that form at the two core cis-acting elements of the GmCaM-4 promoter in pathogen-treated nuclear extracts. We generated GUS reporter constructs harboring various deletions of approximately 1.3-kb GmCaM-4 promoter, and analyzed GUS expression in tobacco plants transformed with these constructs. The GUS expression analysis suggested that the two previously identified core regions are involved in inducing GmCaM-4 expression in the heterologous system. Finally, a transient expression assay of Arabidopsis protoplasts showed that the GmCaM-4 promoter produced greater levels of GUS activity than did the CaMV35S promoter after pathogen or NaCl treatments, suggesting that the GmCaM-4 promoter may be useful in the production of conditional gene expression systems.

This study was performed to identify the maternal risk factors for the low birth weight. During the period from February to June in 1991, the medical record review and questionnaire interview were conducted upon the 465 pregnant women who were admitted to and delivered a baby in 3 general hospitals and an obstetric hospital in Kwangju area. The health and other related information from women who bore the low birth weight infant was compared with those from women who bore the normal birth weight infant. The results obtained were as follows : 1. Maternal age, low body weight at term, illegitimate birth, and maintaining work activity during pregnancy were positively associated with low birth weight. 2. The positive association was revealed between low birth weight and the previous abortion, short gestational weeks, anemia, low maternal weight gain during pregnancy, the obstetric present illness and hypertension. 3. Some maternal working conditions were associated with low birth weight although statistically not significant. 4. In multivariate logistic regression analysis, gestational weeks and maternal weight gain during pregnancy were related with low birth weight.

Bronchiolitis Obliterans Associated with Stevens-Johnson Syndrome: A Case Report

박형철,임채만,고영보,권혁수 연세대학교의과대학 2015 Yonsei medical journal Vol.56 No.2

We report a case of bronchiolitis obliterans associated with Stevens-Johnson syndrome. A 59-year-old man presented with respiratory distress that gradually worsenedover 3 months. He had been diagnosed with Stevens-Johnson syndrome 3 months before admission. He had no history of previous airway disease. On physicalexamination, expiratory breathing sounds were not audible, and a chest X-ray revealed a hyperinflated lung. A pulmonary function test indicated a severe obstructivepattern. Computed tomography scans of inspiratory and expiratory phasesof respiration showed oligemia and air trapping, and both were more prominent on expiration view than on inspiration view. The pathogenesis of bronchiolitis obliteransassociated with Stevens-Johnson syndrome is largely unknown.

박형철,정규원,김병우,신애선,원영주,오재환,정승용,유창식,이봉화 대한대장항문학회 2013 Annals of Coloproctolgy Vol.29 No.5

Purpose: In Korea, anal cancer is rare disease entity with specific clinical characteristics. Therefore, no survival analysis with a sufficient patient population has been performed. The aim of this study was to evaluate the characteristics of Korean anal cancer, focusing on the survival according to tumor histologies, sex, and a specific age group, using the nationwide cancer registry. Methods: Using the Korea Central Cancer Registry, we analyzed a total of 2,552 cases from 1993 to 2010. We assessed the 5-year relative survival by using tumor histology. In addition, survival differences of Surveillance Epidemiology and End Results (SEER) stage were analyzed for both sexes and for young-age cancer (younger than 40 years) and advanced-age cancer (older than 70 years). Results: The 5-year relative survival among anal cancer patients increased from 38.9% for the period 1993–1995 to 65.6% for the period 2006–2010. The anal squamous cell carcinoma was the most common histology and showed better survival than other types of cancer. Females demonstrated better survival than males in all SEER stages. The 5-year survivals for patients in whom anal cancer developed before the age of 40 and at or after the age of 40 were 62.4% and 51.6%, respectively. The 5-year survival for patients in whom cancer developed at or after the age of 70 was much worse than that for patients in whom the cancer had developed prior to that age. Conclusion: Korean anal cancer has certain distinctive characteristics of survival according to tumor histology, sex, and age. Despite limitations on available data, this study used the nationwide database to provide important information on the survival of Korean patients with anal cancer.

Multiple Orthogonal Subcarrier Modulation based High-Speed UHF RFID System for Multiple-/Dense-Interrogator Environments

박형철,Park, Hyung Chul The Institute of Electronics and Information Engin 2016 전자공학회논문지 Vol.53 No.9

본 논문에서는 다중 직교 부반송파 변조 기반의 새로운 UHF RFID 통신 시스템을 제안한다. 태그 송신-리더 수신 통신에서는 4 부반송파를 이용하여 1.6 Mbps까지 전송속도를 향상시킬 수 있다. 회로의 복잡도 증가를 억제하면서도 전송 속도를 향상시키기 위해서, 태그는 부반송파로서 구형파를 사용하고 각 부반송파는 각각의 부하변조기를 이용한다. 다중 직교 부반송파 기반의 변조 방식을 사용하였기 때문에 제안한 통신 방식은 기존의 UHF 대역 RFID 규격을 만족한다. 리더는 OFDM 복조기를 사용한다. 태그가 리더의 CW 반송파를 역산란하므로 리더 복조기에는 반송파 주파수 오프셋 보정회로는 필요하지 않다. 실험에서는 개발 시스템은 10.8 dB의 잡음 밀도당 비트에너지 비에서 10-5의 비트오율 성능을 가짐을 보인다.

독감에 감염된 소아청소년에서의 중성구감소증

박형철,이재희 조선대학교 의학연구원 2018 The Medical Journal of Chosun University Vol.43 No.2

Neutropenia is a common finding in pediatrics with 1.5-9% of children (without malignancy) presenting to hospital found incidentally to be neutropenic. The majority of these pediatric patients with transient neutropenia present with infectious symptoms with an infectious agent proven in approximately 50% of cases, most commonly viral in nature. 270 children, who were diagnosed with influenza infection at the Chosun University Hospital during a 8-year period, were included in the study. Clinical and laboratory feature were analyzed. 46 patients (17%) were neutropenic with no identifiable cause other than the influenza. The incidence of leukopenia was significantly higher in association with influenza B than influenza A (24.0% vs 12.3%). Period from the onset of fever to lymphopenia was significantly longer in association with neutropenia (+) group than neutropenia (−) group. Recovery period of neutropenia was mean 4 days (range 3-7 days). We conclude that mild, transient neutropenia is common among patients with influenza infection and advise that it should not cause alarm or invite specific investigation unless severe or prolonged.
