국내 데이터베이스 구축 시장은 작년 기준으로 3조 6,633억원 규모로 추정된다. 데이터베이스 산업의 지속적인 성장과 맞물려, 데이터 마이그레이션의 중요성도 날로 높아지고 있다. 고객 위치를 찾아주는 g-CRM이나 고객에게 상품을 추천하는 맞춤 설계 기능 등은 모두 고객 데이터베이스, 상품 데이터베이스, 지리정보 데이터베이스 등이 결합되어야 구현 가능한 서비스들이다. 스마트 비즈니스의 핵심 인프라도 통합되고 완전하며 신뢰할 수 있는 데이터베이스라고 할 수 있다. 이러한 데이터베이스의 중요성에도 불구하고, 데이터 마이그레이션 및 통합 과정의 효율적인 수행 방안이나 데이터 검증 방법에 대하여는 구체적인 연구가 부족한 실정이다. 본 연구에서는 다양한 타입으로 존재하는 과학기술분야 콘텐츠들을 대상으로 데이터 마이그레이션을 위한 모델을 설계하였고, 모델을 기반으로 실제 데이터 마이그레이션 작업을 수행한 결과를 제시하였다. 아울러 데이터 마이그레이션 결과에 대한 검증을 위해 데이터베이스의 완전성, 데이터값의 일관성, 관계의 일관성을 검증하였고, ANSI/ASQ Z1.4-2003에서 제시된 샘플링 검사 기법도 적용하였다. 결과적으로 모델 수립에 의한 체계적인 데이터 마이그레이션 수행은 데이터베이스 정합성 및 데이터값의 정확성에 영향을 미치고, 고품질의 데이터베이스를 유지하기 위한 필수 요소라 할 수 있다. The domestic market of database in Korea is estimated to be over 3.663 trillion won. The data migration is getting to be more important along with the continuous growth of the database industry. g-CRM and private recommending function are examples of the service that can be given through coupling among customer database, product database, geographic information database, and others. The core infrastructure is also the database which is integrated, perfect, and reliable. There are not enough researches on efficient way of data migration and integrating process and investigation of migrated data though trends of database in IT environment as above. In connection with this issue, we have made a model for data migration on scientific and technological contents and suggest the result of data migration process adapting that model. In addition, we verified migration's exhaustiveness, migration's consistency, and migration's coherence for investigation of migrated data and database. From the result, we conclude data migration based on proper model has a significant influence on the database consistency and the data values correctness and is essential to maintain high qualified database.

류완호,이원묵,박성하,양천회 한밭대학교 에너지청정기술연구소 2004 에너지청정기술논문집 Vol.4 No.1

국내 석탄화력 발전소에서 폐기되는 석탄회를 이용하여 폐수 중 암모니아성 질소 제거용 흡착제를 제조하고자 NaOH를 반응물로 한 수열합성 반응을 이용, 제올라이트를 합성하였으며 제조된 제올라이트를 실제공정에 활용하기 위하여 흡착실험 및 공정모사를 수행하였다. 또한 흡착제를 구형으로 제조하여 암모니아성 질소의 등온 흡착 공정에 이용하였으며 이 결과 Langmuir, Freundlich 및 Sips 식에 잘 일치함을 알 수 있었다. 고정층에서의 흡착 거동은 축 방향 분산흐름, 입자 내부에서의 표면확산 및 Sips 흡착 등온식을 바탕으로 한 고정층 흡착 모델의 주요 공정 변수에 대한 파과곡선을 잘 모사할 수 있음을 확인할 수 있었다. Zeolite was synthesized from coal fly ash produced by a domestic power plant and applied for the removal of ammonia from waste water. Zeolite was synthezied using a hydrothermal method involving an akaline reaction with NaOH, and adsorption experiments and simulations were performed with the pellectized zeolite. The experimental data obtained from adsorption isotherms were consistent with the Langmuir, Freundlich and Sips equation. Also, most of the correlated results for the fixed bed model based on surface diffusion and Sips adsorption isotherms equation were consistent with the experimental data.

류완호,이원묵,이철우 한밭대학교 에너지청정기술연구소 2004 에너지청정기술논문집 Vol.4 No.1

MSR(Methane steam reforming)공정 중 발생되는 CO_(2)를 제거하기 위하여 CaCO_(3)에 무기바인더를 이용하여 구형의 CaO 반응물질을 제조하였다. 반응물질의 특성을 알아보기 위하여 반응온도, 농도, 접촉시간 등의 운전조건에 대한 변화와 CO_(2)와의 반응성에 대하여 연속 흐름식 반응장치를 이용하여 실험하였다. 반응물질의 소성온도는 850℃에서 반응성이 가장 좋았지만 탈 탄산화 공정을 고려하여 950℃로 결정하였다. GHSV를 3000hr^(-1)으로 고정시켜 놓고 실험한 결과, 반응기의 온도는 800℃, 유입되는 CO_(2)의 농도는 10%에서 반응성이 가장 좋았다. The adsorbent was prepared to separate CO_(2) gas generated from MSR process. Characteristies of carbonation and decarbonation of the adsorbent have been examine continuous reactor system in respect to temperature, concentrations at contact time. The decarbonation of CO_(2) onto adsorbents slowly occurred in this the temperature range from 850℃ to 950℃. However, the maximum carbonation ability was obtained at GHSV of 3000hr^(-1), temperature 800℃ and CO_(2) concentration of 10%(N_(2) balance).

양윤형,이정희,김형진,윤원기,김환묵,김미리 동아시아식생활학회 2005 동아시아식생활학회지 Vol.15 No.1

Proximate analysis, mineral and fatty acid composition of three conventional domestic soybean cultivars and two imported ones including glyphosate-tolerant HS2906 were evaluated by AOAC method, ICP-AES and gas chromatography. There were several differences in the proximate analysis among three conventional domestic soybean cultivars ; higher crude fat in the cultivar Hwanggumkong, higher crude protein in Pungsankong, and higher carbohydrate and crude ash in Duyukong. The ranges of contents of proximate components of domestic cultivars were similar to the data previously reported. There were no significant differences in proximate analysis between conventional soybean WS82 and glyphosate-tolerant HS2906 ; 23.55~23.90% of crudefat, 34.22~35.55% of crude protein, 6.25~6.45% of crude ash, and 25.35~26.47% of carbohydrate. The mineral and fatty acid compositions of HS2906 were similar to those of conventional soybeans previously reported.

Background:Alzheimer's disease (Ad) is a neurodegenerative disorder that is rapidly increasing with the aging society, requiring a need for early diagnosis and prevention. However, diagnosis on AD has only been possible through limited methods such as neuropsychological examination or MRI. AD is characterized by deposition of senile plaques and neurofibrillary tangles in the brain. Aβ peptide in senile plaques seems to play a central role in the neuropathology of AD. Several biochemical markers for AD are available, including reduced Aβ protein, a change in ratio between Aβ40 and 42 and increased level of tau protein in the cerebrospinal fluid (CSF). Methods:This study analyzes anti-Aβ antibody from serums of AD patients using the ELISA. The levels of anti-Aβ antibody from patients with idiopathic Parkinson's disease or stroke and from normal control were compared to that of AD patients. Results:Our results showed a significantly lower anti-Aβ antibody level in AD compared to those with other neurological diseases or control. Conclusions:These data showed that the anti-Aβ antibody level in the serum may be used to diagnose the presence of AD.

Purpose: Dipyridamole stress myocardial perfusion SPECT could predict prognosis, however, long-term follow-up showed change of hazard ratio in patients with suspected coronary artery disease. We investigated how long normal SPECT could predict the benign prognosis on the long-term follow-up. Materials and Methods: We followed up 1169 patients and divided these patients into groups in whom coronary angiography were performed and were not. Total cardiac event rate and hard event rate were predicted using clinical, angiographic and SPECT findings. Predictive values of normal and abnormal SPECT were examined using survival analysis with Mantel-Haenszel method, multivariate Cox proportional hazard model analysis and newly developed statistical method to test time-invariance of hazard rate and changing point of this rate. Results: Reversible perfusion decrease on myocardial perfusion SPECT predicted higher total cardiac event rate independently and further to angiographic findings. However, myocardial SPECT showed independent but not incremental prognostic values for hard event rate. Hazard ratio of normal perfusion SPECT was changed significantly (p<0.001) and the changing point of hazard rate was 4.4 years of follow up. However, the ratio of abnormal SPECT was not. Conclusion: Dipyridamole stress myocardial perfusion SPECT provided independent prognostic information in patients with known and suspected coronary artery disease. Normal perfusion SPECT predicted least event rate for 4.4 years. (Korean J Nucl Med 2000;34:39-54)
