      • 유효 XML 문서를 위한 RDB의 외부키 모델링

        김정희,김정필,곽호영 중앙대학교정보통신연구소 2002 정보통신연구소논문집 Vol.4 No.1

        본 논문은 관계형 데이터베이스에서 테이블들 사이의 복잡한 관계를 DTD(Document Type Definition)에 표현하는 모델링 방식을 제안하다. 테이블간의 외부 키 관계를 DTD내에 모델링하며 추출된 정보 등은 생성된 DTD를 참조함으로써 유효함을 보장받을 수 있게 된다. 모델링 방식은 작업영역에 해당되는 테이블들의 필드들을 순서화하고, 또한 테이블 이름과 해당 테이블 필드의 마지막 순서값을 파악하여 테이블정보를 생성하며, 필드 쌍은 주어진 순서 값들에서 외부 키가 존재하는 순서값들의 쌍으로 구성하게된다. 그 결과 데이터베이스에서 추출된 정보들에 대해 유효한 XML 문서형식을 보장하는 DTD 내용에 외부 키 모델링이 가능했으며, 기존방식보다 DTD 생성단계를 파악하는 과정이 감소됨을 알 수 있었다. In this paper, a modeling scheme is proposed to represent the relation between tables on DTD(Document Type Definition) in DTD makes the extracted information valid by referencing generated DTD. After indexing the fields of corresponding tables, the information of tables is generated by considering the table names and the last index values of tables, and a pair of fields consists of a pair of index values having external key from given index values. As a result, the foreign key modeling can be carried out in DTD which guarantees XML documents format for the extracted information from database, and it is known that effort for understanding procedure of DTD generating steps was effectively reduced by the proposed method than the present existing method.

        Network Modeling and Circuit Characteristics of Aperture-Coupled Vertically Mounted Strip Antenna

        Jeong Phill Kim 한국전자파학회JEES 2011 Journal of Electromagnetic Engineering and Science Vol.11 No.2

        A general analysis of an aperture-coupled vertically mounted strip antenna is presented to examine its circuit characteristics. Based on the present analysis, an equivalent circuit model is developed, and an analytic or semi-analytic evaluation of the related circuit element values is described. The effects of structure parameters on the antenna characteristics were studied with the developed equivalent circuit, and the design curves were obtained. To check the validity of the proposed analysis and design theory, two C-band antennas (5.0 ㎓ and 4.5 ㎓) were designed and fabricated. Their computed characteristics, derived from the proposed network analysis, were compared with the measurement and simulation results. The error of the current model in predicting the operating center frequency was less than 0.50 %. In addition, the observed bandwidth was found to be comparable to the conventional microstrip antennas. All the results fully validated the efficiency and accuracy of the proposed analysis and network model.

        최근 급속히 발전하고 있는 컴퓨터 하드웨어 기술로 이미지, 오디오, 비디오 등의 방대한 멀티미디어 데이터가 비 선별적으로 일반 사용자에게 제공되어지고 있다. 하지만 상이한 해석이 가능한 멀티미디어 데이터의 특성상 정확한 데이터의 전달을 위해 각각의 사용자의 취향을 고려할 수 있는 지능 컴퓨팅 기술. 즉, 개인화 모델의 이용이 필수적이다. 개인화 모델의 구축을 위해서는 사용자의 피드백 정보를 필요로 하게 되는데, 현재까지의 연구는 결과에 대한 만족정도를 사용자가 일일이 조사해야 하는 부담 때문에 사용자에게는 일반적인 환경에서 사용자의 묵시적인 피드백 정보를 이용하는 기술 개발의 필요성이 강조되고 있다. 본 논문에서는 묵시적으로 사용자의 시각 정보 및 행위 정보를 이용하여 사용자의 부담을 줄이는 동시에 적응 및 학습 능력을 갖는 지능 사용자 인터페이스를 적용한 내용기반 이미지 검색 시스템을 구현하였다.

        관상동맥 조영술 후 체위변경이 불편감과 출혈에 미치는 효과

        김필자,정정인,노정숙,나향,김가연,김경선,이근화,이은숙,홍순복,황정화,김선경,한송이,김희순 병원간호사회 2009 임상간호연구 Vol.15 No.1

        Purpose: The purpose of this study was to examine the effect of position change on discomfort and bleeding in patients undergone coronary angiography with a vascular device and required bed-rest. Method: This study utilized nonequivalent control group non-synchronized design. Data were collected from 118 inpatients after coronary angiography and stayed in general ward at Y hospital in Seoul, from June 5 to August 12, 2008. After coronary angiography, position change was performed to the experimental group who consisted of 59 patients. They stayed in supine position just after angiography and then head-up position with 15 degrees was applied 1 hour later. After that, they could change the position alternatively into lateral position with leg down and supine position. The control group was positioned keeping the affected leg immobile with supine position for 4 hours. Results: The experimental group reported significantly more comfortable than control group after position change. There were no significant differences in the grades of bleeding or hematoma at puncture site between the two groups. Conclusion: The position change in patients undergone angiography could be applied without any harm such as bleeding or hematoma, but effective in reducing back pain and subjective patients' discomforts.

      • Predictors of residual disease in subsequent radical hysterectomy specimens after conization in patients with cervical cancer - Possible clues for less radical surgery

        ( Phill Seung Jung ),( Yeon Sik Na ),( Shin Wha Lee ),( Jeong Yeol Park ),( Jong Hyeok Kim ),( Young Man Kim ),( Joo Hyun Nam ),( Young Tak Kim ),( Dae Yeon Kim ) 대한산부인과학회 2012 대한산부인과학회 학술대회 Vol.98 No.-

        To correlate pathologic findings on conization specimens and other clinical parameters with residual disease in radical hysterectomy specimens in patients with cervical cancer to determine which subgroup of patients may be eligible for less radical surgery Between 2003 and 2011, we perfomed 472 conizations before treating cervical cancer patients. The exclusion criteria were the patients who were given neoadjuvant chemotherapy and/or definitive CCRT and/or radical trachelectomy and the patients whose pathologic reports were missing or unclear. A total of 292 patients who underwent radical hysterectomy after conization were included in this retrospective study. Mean age of this patients were 51.7 years (28-85) and mean size of residual tumor was 1.3cm (0-7.3 cm). FIGO stage distribution were 17 patients in IA1, 21 in IA2, 233 in IB1, 10 in IB2 and 11 in others. At radical hysterectomy, 87 patients (30%) had no residual cancer, while 205 patients (70%) had residual cancer. Univariate analysis showed that positive resection margin and tumor size more than 2cm were significant factors for predicting residual disease. These factors also significant in a multivariate analyisis (positive resection margin OR 6.869, 95% CI 2.734-17.262, p<0.001; tumor size >2cm OR 3.090, 95% CI 1.744-5.474, p<0.001). Of the resection margin status, Positive endocervical and deep margin were significant but not significant in exocervical margin. The patients with negative resection margin and small tumor (< 1 cm) had no residual disease and no recurrences in the median FU of 32 months. Positive resection margin on conization and large tumor size (>2c m) were significant factors for predicting residual cancer after radical hysterectomy. Using these factors, we can develop the predicting models for detecting subgroup of patients who are eligible for less radical surgery.

      • GO-10 : Poor prognosis after conservative surgery in stage I mucinous epithelial ovarian cancer

        ( Phill Seung Jung ),( Shin Wha Lee ),( Jeong Yeol Park ),( Dai Shik Suh ),( Dae Yeon Kim ),( Jong Hyeok Kim ),( Yong Man Kim ),( Young Tak Kim ),( Joo Hyun Nam ) 대한산부인과학회 2014 대한산부인과학회 학술대회 Vol.100 No.-

        목적: To evaluate the oncologic safety and to identify prognostic factor for recurrence in premenopausal women with stage I mucinous epithelial ovarian cancer (mEOC) who underwent conservative surgery. 방법: We enrolled 97 patients who were 1) premenopausal at the time of surgery and 2) confirmed to be the FIGO stage I. The surgical procedure of conservative surgery was unilateral salpingo-oophorectomy with/without contralateral ovarian wedge resection. 결과: The median age was 33 (range: 13-50) years at the time of surgery. Sixty-three (64.9%) patients were stage Ia, and 34 (35.1%) were Ic. Fifty-three (54.6%) patients underwent conservative surgery, and adjuvant chemotherapy was administrated to 61 (62.9%) patients. During 73.7 (range: 7.1-243.5) months of the median follow-up duration, 13 (13.4%) patients recurred and 8 (8.2%) of them died of disease. Among patients who underwent conservative surgery, there were 10 recurrences and the majority of recurred site was intraperitoneal cavity (n=8) with median age of 25 (range: 14-46) and median PFS of 17.8 (range: 5.1-53.3) months. In multivariate analysis, a significantly poorer prognosis was noted in patients who underwent conservative surgery (HR: 6.26, 95% CI: 1.53-25.53, p=0.011) and in patients with high preoperative CA-125 (HR: 1.98, 95% CI: 1.26-3.11, p=0.003). In patients with high preoperative CA-125 (>35U/mL, n=48), conservative surgery caused significantly higher recurrence rate (HR: 5.73, 95% CI: 1.22-27.03, p=0.027). 5-year disease-free survival rate was significantly lower in patients who underwent conservative surgery than in patients who did not (77.7% vs. 94.2%, p=0.047). 결론: In conclusion, conservative surgery might cause the poor prognosis in premenopausal women with stage I mEOCs, particularly with high preoperative CA-125 level. The further multicenter study with larger cohort would be needed to verify the oncologic safety of conservative surgery in mEOCs.
