목 적 : 본 연구는 저출생 체중아로 출생한 소아에 있어서 학동기 및 청소년기 소아 천식의 중증도에 미치는 영향에 관해서 후향적으로 검토하였다. 방 법 : 대동병원 소아과와 호흡기내과에 통원 중에 있거나 부산 동래구 및 연제구 소재 개인의원에서 대동병원으로 전원 된 천식 환자 중에서 8세 이상 18세 이하의 소아 및 청소년을 대상으로 출생체중을 기준으로 1,500 g 이상 2,500 g 미만인 15명을 추출하여 연구군으로 하고 출생체중 2,500 g 이상이며 연구군의 나이에 일치하는 순서대로 2명씩 추출하여 이 30명을 대조군으로 하였다. 결 과 : 양군을 비교한 결과 천식 중증도는 연구군에서 유의하게 높았다.(P=0.015) 또 흡입 스테로이드 약의 사용 빈도(증례군 13명/15명, 대조군 4명/30명 : P=0.0001)와 사용 기간에 있어서도 연구군에서 유의하게 높게 나왔다.(P= 0.009) 혈중 총 IgE치와 아토피피부염의 유병률은 대조군에서 높았다.(각각 P=0.007, P=0.0001) 폐기능 검사와 PC(20), 특이 IgE 항체는 두 군 사이에 유의한 결과를 볼 수가 없었다.(P>0.05) 결 론 : 천식의 중증도와 흡입 스테로이드 사용의 빈도와 기간 등으로 미루어 볼 때 저출생 체중은 소아 천식의 중증도를 증가시키는 요인 일 수 있음을 시사한다. Purpose : Over the past several decades, the survival rates of low birth weight(LBW; birth weight <2,500 g) infants have been improving. Many of these infants have had bronchial asthma(BA) at childhood and aldolescence. The aim of this study is to investigate whether LBW influenced the severity of BA in prealdolescent children and aldolescence by a retrospective case control study. Methods : 15 LBW children(1,500 g<birth weight<2,500 g) between 8 year-old and 18 year-old with BA visiting Dae-dong hospital as the case group were compared with 2 BA children to each case as the control group(total 30 children) on the basis of following criteria : the same age, he/she attended Dae-Dong hospital or local medical center after 8 years old, birth weight was more than 2,500 g. Asthma severity was modified from 2003 Guideline for management of childhood asthma at The Korean Academy of Pediatric Allergy and Respiratory Disease. PFT(Pulmonary function test) were measured using a portable spirometer. The value are expressed as percentage predicted using standard reference values. Total IgE and specific IgE Ab. were assessed by the PRIST method and MAST Allergy Test. Methacholine challenge test and PC20 was assessed by the Masterlab. Results : LBW group had : a significantly more severe symptoms between 8 year-old and 18 year-old than control group.(P=0.015) A significantly more used to ICSs(Inhaled corticosteroids) and add-on therapy than control group.(P=0.009)(P=0.0001) There were no significant differences in the PFT and PC(20) and specific IgE Ab. between LBW group and control group. But, total IgE level is higher in the control group than in the LBW group. Conclusion : These results suggest that LBW is a risk factor for the severity of BA. We suggest that infants with birth weight of less than 2,500 g have a more severe risk of asthma during prealdolescent children and aldolescence than who were birth weight of more than 2,500 g.

Malignant peritoneal mesothelioma is a rare neoplasm that arises from the mesothelium of a serosal cavity and is a rapidly fatal disease with a median survival of 4 to 12 months for untreated cases. Recently, we experienced a case with malignant peritoneal mesothelioma who was suspected hepatocelluar carcioma by abdominal CT scan and was confirmed by biopsy including immunohistochemical stain(calretinin) after surgery. We performed tumor excisions and wedge resection of the liver(segment Ⅷ)and inserted Tencoff catheter in abdominal cavity at 25th day of post-operation. We treated with intraperitoneal paclitaxel(25mg/m^(2)/day for 5 days) six courses monthly. She was well tolerable and is still living without any evidence of recurrence for 14th month of post-operation.

The objectives of this study are 1) to find out the shear behavior and shear capacity of RC bare frames, brick-infilled RC frames, 2) to evaluate the equation of the shear capacity of two types of RC frames by comparison the Japanese Standard and modified equation adopting the test results. The main variable is the absence of brick infill wall. The test results show that the shear capacity of specimen IF-4.2 is 2.3 times as high as that of the specimen IF-4.2.The shear behavior of RC bare frame which is governed by predominant flexural yielding is changed to predominant shear yielding by affection of the brick infill wall. A comparison of the results obtained by the Japanese Standard equation and the modified equation to the test data indicates that the proposed equation is compatible with the test results.

In this study, timing model, analysis of LIN protocol and design of the damper control system for vehicle's climate system using LIN, it is inevitable to study the timing behavior of the networked control system for vehicle, because the LIN communication protocol influences the control network system in vehicles. Therefore, the performance of a distributed control climate system in vehicle using LIN protocol can be improved as long as the timing behavior of the protocol is creditable. Through the design of the damper control system for vehicle's climate system and the timing analysis of the transmitting LIN message, all relevant timing parameters that affect the message transmission time are defined. As a result of the analysis, a timing equation of the transmitting message and control vehicle's damper control climate system are composed of these timing parameters and transmit signal. Using this result, the transmission of LIN message in vehicle's network system can be predicted. Furthermore the LIN application software that has been already used in LIN applications can be verified by the damper control system for vehicle's climate system using LIN.
