Paenibacillus macerans 유래의 cycloinulooligosaccharide fructanotransferase (CFTase) 유전자(cft, 2832 bp, 103.8 kDa)를 효모 표층발현 vector인 pCTcon (GAL1 promoter)에 subcloning 하였다. 구축된 pCTECFTN (9.0 kb)를 숙주세포인 s. cerevisiae EBY100에 형질전환한 후, uracil이 결핍된 배지와 inulin 함유배지에서 선별하였다. cft 유전자는 GAL1 promoter에 의해 효모 형질전환체에서 성공적으로 발현되었다. inulin으로부터 cyclofructans (CFs)로 생산하는 효소적 능력으로부터 표층발현 유무를 확인하였다. YPDG배지에서 48시간 배양 후 분획한 균체는 5.52 unit/ l 의 활성을 보였다. CF 생산을 위한 효소의 최적 반응 조건으로 pH 8.0, 반응온도 $50^{\circ}C$, 기질농도 5%, 기질은 Jerusalem artichoke 등의 inulin과 표층 발현 CFTase 효소반응 결과, cycloinulohexaose (CF6), cycloinuloheptaose (CF7), 그리고 cycloinulooctaose (CF8)이 생성되었고, 이 중에서 CF6가 주 생성물이었다. The cycloinulooligosaccharide fructanotransferase (CFTase) gene (cft) from Paenibacillus macerans was subcloned into the surface display vector, pCTcon (GAL1 promoter). The constructed plasmid, pCTECFTN (9.0 kb) was introduced to S. cerevisiae EBY100 cell and then east transformants were selected on the synthetic defined medium lacking uracil and on the inulin containing medium. The surface display of CFTase was confirmed by immunofluorescence microscopy and its enzymatic ability to form cycloinulooligosaccharides(cyclofructans, CFs) from inulin. The total activity of the CFTase was reached about 5.52 unit/1 by cultivation of yeast transformant on YPDG medium. The optimized conditions determined were as follows; pH, 8.0; temperature, $50^{\circ}C$ ; substrate concentration, 5%; inulin source, Jerusalem artichoke. By the reaction with inulin, CFs consisting of cycloinulohexaose (CF6), cycloinuloheptaose (CF7), and cycloinulooctaose (CF8) were produced and CF6 was the major product.

Purpose: This study measured the burden of disease in Korea related to outdoor air pollution using disability-adjusted life year (DALY). Materials and Methods: As a risk factor of outdoor air pollution, particulate matter with a diameter less than 10 ${\mu}m$($PM_{10}$) was used. First, $PM_{10}$-related diseases and their relative risk (RR) were selected by means of a literature review. Second, population attributable fractions were computed by using formulae including RR and population exposure to $PM_{10}$. Third, DALYs of $PM_{10}$-related diseases in Korea were estimated. Finally, the attributable burden of disease due to $PM_{10}$ was measured as the sum of the products that multiplied the DALYs of $PM_{10}$-related diseases by their population attributable fractions. Results: The disease burden of PM10 was 6.9 DALY per 1,000 persons in 2007. The attributable burden of $PM_{10}$ was 2.68 for lung cancer, 2.41 for COPD, 0.62 for ischemic heart disease, 0.61 for pneumonia, 0.55 for asthma, and 0.03 for preterm. Conclusions: This study showed the environmental burden of disease of $PM_{10}$ and burden of $PM_{10}$-related disease through objective data. It also suggested that active efforts are needed to continuously measure and reduce the burden of environmental diseases in Korea.

독일 기록관리 담론에서의 평가론

김현진,Kim, Hyun-Jin 한국기록학회 2006 기록학연구 Vol.0 No.14

이 글은 독일 기록관리 이론의 역사를 평가론 중심으로 개괄한다. 18세기 이전 독일의 기록관리의 목표는 법률적, 정치적 지식을 조직하는 것이었다. 따라서 기록 소유자의 법률적 권리보전을 위해 특별히 중요한 증명서나, 정치적으로 중요한 문서들만 선별, 관리되었다. 19세기에, 구체제의 붕괴로 보호해야 할 특권이 없어지면서 기록관리의 목적은 연구기능을 지향하게 되었다. 다양한 기관에서 생산되어 집적된 기록들을 조직하기 위해 출처주의가 확립되었고, 학문적인 필요에 부합하는 내용지향적인 평가방식이 선호되었다. 1차 대전은 현대 기록학 이론 형성의 결정적인 계기가 된다. 전쟁수행 중 생산된 방대한 양의 기록을 처리해야 하는 당면 과제가 종전 이후의 민주화 분위기와 결합하여 출처 지향적 평가론이 형성된다. 기록의 가치는 생산기관의 업무와 활동을 증거하는 능력에 따라 평가되는 것이다. 나찌 시대를 지나 온 전후 독일의 반(反)관료제적인 분위기 속에서 출처 지향적 평가론 대신 내용지향적인 평가방식이 다시 등장한다. 봄스로 대표되는 이 이론은 20세기 후반 다큐멘테이션 전략 이론의 토대가 된다. In diesem Aufsatz wird die Geschichte der Bewertungsdiskussion in Deutschland vorgestellt. Bis zum 18. Jh. war das Ziel der Archivarbeit die Systematisierung der rechtlichen und politischen Kenntnissen. Der juristisch geschulte Archivar hob Unterlagen in der Regel aus $Gr{\ddot{u}}nden$ der Rechtssicherheit auf. Vernichtet wurde, was schon seit $l{\ddot{a}}ngerem$ im Archiv lag. Nach dem Zusammenfall des alten Regimes haben die Archivare keine mehr mit dem Recht des Herrschers zu tun. Und die Archive wurden zu $Lagerst{\ddot{a}}tten$ der Geschichte und Forschung. $F{\ddot{u}}r$ den Ordnung der Archivgut, die aus den verschiedener Dienststellen stammten, wurde das Provenienzprinzip gebildet. Die Archivare richtete sich auf das inhaltsorientierten Bewertungsverfahren, das die wissenschaftlichen $Bed{\ddot{u}}rfnisse$ befriedigte. Der Anlass der Bildung der modernen Archivtheorie war der ersten Weltkrieg. Das Problem, wie man die Massenakten, die $W{\ddot{a}}hrend$ dieses Krieges entstanden, behandeln sollten, $f{\ddot{u}}hrte$ unter dem $Einflu{\ss}$ der Demokratie zur Bildung der Provenienz-orientierte Bewertungsdiskussion. Aufbau, Zielsetzung und Verfahren der aktenbildenden Stelle bildeten den Ausgang der Bewertung. Im Klima ${\ddot{o}}ffentlicher$ $B{\ddot{u}}rokratieablehnung$ der 50er und 60er Jahren wurde die inhaltsorientierte Auswahl wieder die vorherrschende Methodenvorgabe. Diese Theorie, die Booms vertritt, $f{\ddot{u}}hrt$ zu der Theorie der dokumentation strategy von Ende 20. Jh.

Nd:YAG 레이저에 의한 다층 박막의 미소 점 마킹

김현진,신용진,Kim, Hyun-Jin,Shin, Yong-Jin 한국광학회 2004 한국광학회지 Vol.15 No.4

콤팩트디스크(CD-R; Compact DiskRecordable)를 성분별로 분리하여 제작하고, 다층 박막 구조를 만들어서 레이저빔의 에너지를 변화시켜 가면서 조사하여 각 성분 층에서의 최적 미소 점 마킹 조건과 홈 형성 과정에 관하여 연구하였다. 본 연구는 Q-스위치 Nd:YAG 레이저를 이용하여 준비된 각 시료의 표면에 27∼373 mJ 빔을 80 $\mu\textrm{m}$의 점적 크기로 조사하여 샘플에 형성된 흠 형태를 광학현미경(OM; Optical Microscope)과 광 결맞음 단층촬영기(OCT; Optical Coherence Tomography)로 비교-관찰하여 미소 점 마킹의 형성 과정을 분석하였다. 다층 박막에서 용융된 기판 층은 짧은 시간동안 충분한 열 흐름이 발생하여 증배의 형성을 야기하며, 반사 층과 염료 층 사이에 흡수된 에너지는 염료를 용융시키고 체적을 증가시켰으며, 증배가 식으면서 표면장력의 영향 및 레이저빔에 의한 순간적인 시편의 온도상승으로 기화와 반동압력에 의한 질량흐름 때문에 두 층의 경계면에서 홈과 외륜의 발생을 설명할 수 있었다. 따라서 다층 박막에서의 미소 점 마킹의 형성 과정은 표면장력, 용융 점성력, 층 두께, 다층 박막 성분 물질의 물리화학적ㆍ광학적 성질과 관계가 있음을 알 수 있었다. We separated the multilayer structure of CD-R(compact disk-recordable) and investigated optimal spot marking conditions and physical and chemical transitions in response to various laser beam energh levels. Spot marking(80 ${\mu}{\textrm}{m}$ spot size) was produced on the surface of each layer using a Q-switched Nd:YAG laser between 27 mJ and 373mJ. By investigating resulting pit formation with Optical Microscopy(OM) and Optical Coherence Tomography(OCT), we analyzed the formation process of spot marking in the multilayer structure of different chemical composition. The localized heating of the substrate in the multilayer thin film caused the short temporal thermal expansion, and absorbed optical energy between reflective and dye interfaces melted dye and increased the volume. During the cooling phase, formation of pit and surrounding rim can be explained by three distinct processes; effect of surface tension, evaporation by spontaneous temperature increase due to laser energy, and mass flow from the recoil pressure. Our results shows that the spot marking formation process in the multilayer thin film is closely related to the layers' physical, chemical, and optical properties, such as surface tension, melt viscosity, layer thickness, and chemical composition.

다중 주사 경로 회로 기판을 위한 내장된 자체 테스트 기법의 연구

김현진,신종철,임용태,강성호,Kim, Hyun-Jin,Shin, Jong-Chul,Yim, Yong-Tae,Kang, Sung-Ho 대한전자공학회 1999 電子工學會論文誌, C Vol.c36 No.2

The IEEE standard 1149.1, which was proposed to increase the observability and the controllability in I/O pins, makes it possible the board level testing. In the boundary-scan environments, many shift operations are required due to their serial nature. This increases the test application time and the test application costs. To reduce the test application time, the method based on the parallel opereational multiple scan paths was proposed, but this requires the additional I/O pins and the internal wires. Moreover, it is difficult to make the designs in conformity to the IEEE standard 1149.1 since the standard does not support the parallel operation of data shifts on the scan paths. In this paper, the multiple scan path access algorithm which controls two scan paths simultaneously with one test bus is proposed. Based on the new algorithm, the new algorithm, the new board level BIST architecture which has a relatively small area overhead is developed. The new BIST architecture can reduce the test application time since it can shift the test patterns and the test responses of two scan paths at a time. In addition, it can reduce the costs for the test pattern generation and the test response analysis. 인쇄 회로 보드 수준의 테스팅을 위해 제안된 IEEE 표준 1149.1은 보드상의 테스트 지점에 대한 제어용이도와 관측용이도를 향상시켜 보드의 테스트를 용이하게 해준다. 그러나, 경계 주사 환경에서는 테스트 입력과 테스트 결과에 따른 데이터가 하나의 주사 연결에 의해서 직렬로 이동된다. 이는 테스트 적용시간을 증가시키고 따라서 테스트에 드는 비용을 증가시킨다. 테스트에 소모되는 시간을 줄이기 위해 병렬로 다중주사 경로를 구성하는 방법이 제안되었다. 하지만 이는 여분의 입출력 핀과 내선을 필요로 한다. 더구나 IEEE 표준 1149.1은 주사 경로 상에 있는 IC들의 병렬 동작을 지원하지 않기 때문에 표준에 맞게 설계하기가 어렵다. 본 논문에서는 하나의 테스트 버스로 두 개의 주사 경로를 동시에 제안하는 다중 주사 경로 접근 알고리즘에 기초하여 적은 면적 오버헤드를 가지고 빠른 시간 내에 보드를 테스트할 수 있는 새로운 보드수준의 내장된 자체 테스트 구조를 구현하였다. 제안된 내장된 자체 테스트 구조는 두 개의 주사 경로에 대한 테스트 입력과 테스트 결과를 이동시킬 수 있으므로 테스트에 소모되는 시간을 줄일 수 있고 또한 테스트 입력의 생성과 테스트 결과의 분석에 소모되는 비용을 줄일 수 있다.

`Purpose: To analyse the postoperative anatomical changes of maculae using optical coherent tomography after internal limiting membrane peeling during vitrectomy. Methods: A retrospective review of 22 patients (22 eyes) who underwent vitrectomy with internal limiting membrane peeling was performed. Age, sex, fundus findings, BCVA, operation methods, complications, and postoperative OCT findings were recorded. Results: Of 22 eyes, 12 eyes had epiretinal membranes, 5 eyes had macular holes, and 5 eyes had diffuse diabetic macular edemas. Eighteen of 22 eyes underwent internal limiting membrane peeling using ICG, with 1 eye treated with triamcinolone and 3 eyes treated with nothing. The postoperative improvement of BCVA was statistically significant in epiretinal membrane and diffuse macular edema patients (p<0.05), but insignificant in macular hole patients (p>0.05). Postoperative OCT findings of 17 eyes showed that they had returned to normal shape and thickness. However, among the 18 eyes that underwent ICG dye-assisted ILM, 3 eyes showed irregular macular thinning and 1 eye showed macular cystic changes. One eye treated with triamcinolone presented with a recurrent cytoid macular edema. No postoperative complications or recurrences were reported by epiretinal membrane patients. Conclusions: Changes to macular shape did not significantly affect the final BCVA after internal limiting membrane peeling, but they can cause changes to the microstructure of maculae. Therefore, caution during surgery and close follow-up are necessary.`

Purpose: To investigate the clinical characteristics and disability rates of patients seeking expert consultation for legal reasons because of ophthalmologic symptoms. Methods: We analyzed the gender, age, reason for consultation, and result of consultation, among other factors, by retrospectively examining the medical files of 89 patients from January 1999 to December 2004. Results: Out of 89 patients, men constituted 76.4% and patients in their forties constituted 23.0%. The most common reason for consultation was a traffic accident (64.0%), followed by a medical lawsuit (11.2%). Forty-nine patients (55.1%) were diagnosed with a disability, while 30 patients (33.7%) were not. Diagnostic decisions for the other 10 patients (11.2%) were deferred. Optic atrophy was the most frequent cause for deteriorating visual acuity in patients, accounting for 19 cases, and diplopia caused by orbital wall fracture was also prevalent (9 patients). Among the resulting types of damage, brain damage was the most frequent, while the percentage of patients with an impairment in the visual system was approximately 29.0% among the patients diagnosed with a disability. Conclusions: Our results will be helpful in elucidating the clinical characteristics of patients referred to the ophthalmic clinic for consultation because of legal concerns.

Purpose: This study was designed to assess the diagnostic value of scanning laser polarimetry with variable corneal compensation (GDx-VCC) in the diagnosis of preperimetric glaucoma. Methods: The study included 132 eyes of 132 patients with normal intraocular pressure, including 38 normal eyes, 60 eyes with pre-perimetric glaucoma, and 34 eyes with early glaucoma. The parameters of GDx-VCC were analyzed and compared in these groups using ANOVA. The parameter with the most powerful diagnostic value was defermirred by an ROC curve, and it`s sensitivity and specificity were calculated. Results: Among GDx-VCC parameters, NFI was the most valuable parameter that could detect pre-perimetric glaucoma in normal eyes. A cut-off value of 12 was the optimal NFI value, which offered the highest sensitivity and specificity in discriminating between normal and pre-perimetric glaucomatous eyes. However, there were no statistically significant differences in GDx-VCC parameters between pre-perimetric and early glaucomatous eyes. A statistically significant correlation was found between NFI and visual field indices in early glaucomatous eyes. Conclusions: GDx-VCC can be useful as a screening test for early detection of pre-perimetric and early glaucoma with normal intraocular pressure.
