근류형성에 의한 생물학적 질소고정기능을 갖는 여러종의 근류균을 대상으로 분자생물학적 계통 분류의 기초자료를 얻기 위하여 Azorhizobium, Bradyrhizobium, Mesorhizobium, Rhizobium, Sinorhizobium 속의 33 균주에 대한 ITS 영역의 염기서열을 이용한 계통 분류가 이루어 졌다. 이들 균주중 대부분의 균주는 한 종류의 ITS 영역을 가지는 반면, 일부균주는 2개의 서로 다른 ITS 염기서열을 가지는 것으로 나타났다. 실험에 이용된 모든 균주들간의 ITS 영역의 염기서열 상동성은 28 - 95%로 매우 변이폭가 컸으며, 이들 염기서열의 계통 분석에 의하면 4가지 그룹으로 구분되었다. Sinorhizobium 속의 모든 균주 및 Rhizobium giardinii 는 그룹 I으로 구분되었다 그룹 II는 R. giardinii를 제외한 모든 Rhizibium 속의 균주를 포함하고 있으며, 계통수의 topology는 매우 불안정한 것으로 나타났다. 특히, R. radiobacter와 R. rubi는 계통분류학적 위치가 불명확한 것으로 나타났다. Bradyrhizobium 속의 균주는 Azorhizobium caulinodans 와 함께 그룹 III로 구분되었고, 그룹 IV는 Mesorhizobium 속의 균주로 이루어 ㅈ다. 특히, Mesorhizobium 속균주의 ITS 영역의 염기서열 상동성이 높게 나타났다. The phylogenetic relationships for 33 strains belonging to the genera Azorhizobium, Bradyrhizobium, Mesorhizobium, Rhizobium and Sinorhizobium were conducted by the sequence analyses of the ITS regions. The sequence homologies of these strains showed the high variations(28.0 - 94.9%). According to the phylogenetic analysis of ITS regions. 37 ITS clones from 33 strains of 32 species were classified into four groups. Group I included all strains of the genus Sinorhizobium as core members and R. giardinii as a peripheral member. The genus Rhizobium strains were clustered into group II which was very heterogeneous and the tree toplogy of this group were very unstable. Among the members of group II. the taxonomic position of R. radiobacter and R. rubi was not clearly identified on the basis of ITS I regions. R. undicola and R. vitis were remotely related with other Rhizobium strains including R. leguminosarum, R. galegae, R. gallicum, R. mongolense, R. tropici, R. hainanense, R. rhizogense and R. huautlense of group II were supposed to be loosely related to R. leguminosarum. While the stains of the genera Bradyrhizobium constituted group III with Azorhizobium caulindans, the strains of the genus Mesorhizobium formed group IV on the relatively high sequence homology level.

We have investigated the latchup characteristics of BLIBILLi (Buried Layer / Buried Implanted Layer for Lateral Isolation) retrograde twin well CMOS that has blanket high energy ion implanted buried layer to intend for more improvement of latchup compare to conventional Retrograde Well and BILLI structures. We explored the dependence of various latchup characteristics such as n+ trigger latchup and p+ trigger latchup characteristics on the buried layer implant doses. We show various DC latchup characteristics that allow us to evaluate each technology and suggest guidelines for the reduction of latchup susceptibility.

본 연구는 SiC 용액 성장에서 Cr 40 %가 첨가된 Si melt 내부의 용액과 탄소흐름의 변화를 수치적으로 분석하여 장시간 성장과 고품질의 SiC 단결정을 얻기 위한 최적공정 조건의 설계를 목적으로 진행하였다. 수치 시뮬레이션으로는 crystal growth simulator ($CGSim^{TM}$, STR Group Ltd.)가 사용되었다. 결과적으로, 성장온도, 종자정축과 도가니축의 회전속도 및 성장 시 종자정의 위치에 따라 melt내부의 용액 흐름과 탄소흐름의 속도 및 방향이 변화함으로써 더 균일한 온도구배를 형성하여 안정적인 성장이 이루어지는 조건을 확인하였다. 그러므로, 성장조건들을 조절함으로써 시뮬레이션 상에서 실험조건의 최적화가 가능하였고 향후 실제 실험에서도 많은 도움이 될 것으로 예상된다. In this study, numerical simulation was performed to focus on optimized process condition for obtaining a long-term growth and high quality SiC crystal. It could be optimized by considering the change of fluid and a carbon flow in the Si melt added with 40 % Cr. The Crystal Growth Simulator ($CGSim^{TM}$, STR Group Ltd.) was used as a numerical simulation. It was confirmed that many parameters such as temperature, rotation speed of seed crystal and crucible, and seed position during the crystal growth step had a strong influence on the speed and direction of solution flow for uniform temperature gradient and stable crystal growth. The optimized process condition for the solution growth of SiC crystal was successfully exhibited by adjusting various process parameters in the numerical simulation, which would be helpful for real crystal growth.

Background: Endobronchial ultrasound-transbronchial needle aspiration (EBUS-TBNA) is currently performed first for the mediastinal nodal staging of non-small lung cancer (NSCLC). However, unsuspected lymph node metastases leading to upstaging are found during the final histopathologic evaluation of surgical specimens. Purpose of our study was to evaluate the characteristics of upstaged lymph nodes and the its effects on survival in patients with NSCLC. Methods: We performed a retrospective review from 2009 to 2019 at tertiary-care academic hospital. Patients who diagnosed NSCLC with post-operative pathologic N2 positive lymph node were included. Nodal upstaging was defined as the unexpected pathological finding of metastasis in N2 nodes in patients who were presumed to have clinical N0 or N1 with preoperative staging. Results: Of 177 patients with positive N2 node postoperatively, overall rate of nodal upstaging was 53.1% (94 patients). The baseline characteristics did not differ significantly between upstaged and unchanged patients. Upstaged patients were more likely to receive adjuvant chemotherapy compared to unchanged patients. Culprit nodes leading to upstaging were subcarinal (38.3%), paratracheal (36.2%), and aortic nodes (21.3%). The size of upstaged node was less than 5mm in EBUS. Threeyear mortality was not different between two groups, but lower rate of mortality was observed after excluding inaccessible lymph node. Progression-free survival was significantly higher in the upstaged patients. Conclusion: Nodal upstaging was mainly attributed to the small mediastinal nodes or aortic nodes that are not accessible by EBUS-TBNA and did not influence three-year mortality. After excluding inaccessible lymph node, even higher survival was found in the upstaged patients than the unchanged patients with the same stage.
