대장균 세포내 단백질 분해효소, protease Pi의 정제와 특성
이영섭,곽태환,임정빈,정진하 한국미생물학회 1986 미생물학회지 Vol.24 No.2
A periplasmic endoprotease, named protease Pi, was purified to homogeneity from Escherkchia coli by conventional procedure with insulin as substrate. This enzyme degrades insulin and glucagon to trichloroacetic acid-soluble meterials, but shows little or no hydrolysis of bovine serum albumin, casein or globin. Its molecular weight was 110, 000 when determined by gel filtration on Sephacryl S-300 and was 105, 000 when estimated by polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate. Thus, it appears to be single polypeptide. This snzyme is metalloprotease, since it is completely inhibited by o-phenanthroline and can be activated by addition of divalent metal cations, such as $Mg^{2+}\;and\;Co^{2+}$. It is destinct from protease Ci, a cytoplasmic insulin degrading enzyme, since protease Pi is localized to the periplasm. Since protease Pi selectively degrades GTP cyclohydrolase I, it appears to play a role in the regulation of pteridine biosynthesis.

By the increasing concern about Sasang Constitution Medicine, its practical use is considered very important in disease prevention and medical treatment. However, the method of constitution classification is depending on the doctor's clinical trials because of the lack of the objective test criteria. This study is trying to improve the objectiveness of diagnosis using a new statistical method, decision tree. Decision tree method-a classification technique in the statistical analysis- was used to analyze the result of QSCCII instead of using discriminant analysis. As a result, 16 among 121 QSCCII questions was selected as important questions and 21 terminal nodes was built to classify the constitution. Using only 16 questions shown in the result of decision tree, we can diagnose and interpret the constitution easily and effectively.
Product Formula for C-semigroups
이영섭 서울여자대학교 자연과학연구소 2012 자연과학연구논문집 Vol.24 No.-
We establish product formula for contraction C-semigroups. We use the fact that convergence of Laplace transforms of C-semigroups which are strongly equicontinuous implies the convergence of C-semigroups. So the approximating operators to a generator need not be generators of C-semigroups and the approximating operators to a C-semigroups also need not be a C-semigroup.

이 논문은 우리나라에서 불거지고 있는 양극화 문제의 현황, 원인 및 대응방안을 세계화와 관련해 살펴본다. 여러 자료에 기초해볼 때, 최근의 양극화 심화현상은 추세적인 것이 아니며 외환위기 이후 수년간 개선되어 오던 양극화 문제가 2003년 이후 다시 악화되는 경향으로 반전된 것이다. 또한 상류층의 비중이 대체적으로 변함이 없는데 빈곤층이 확대되어 양극화가 심화된 것으로 나타나고 있다. 최근의 양극화 현상은 경기적 원인에 기인한 바가 가장 크지만 적하효과가 약화된 구조적 원인도 양극화를 확대시키는 데 기여하고 있다. 그러나 세계화와 기술진보 등의 근본적 원인은 현재의 양극화를 직접적으로 촉발한 요인이라고 보기는 힘들며, 양극화 추세에 영향을 미치는 경우라 하더라도 세계화 요인보다 기술진보 요인이 더 큰 영향을 미쳐오고 있는 것으로 보인다. 따라서 양극화에 대한 처방은 양극화의 원인과 결부지어 제시해야 한다. 우선 세계화와 기술진보 같은 메가트렌드는 적극적으로 활용해야 한다. 세계화를 추진하는 과정에서 불가피하게 나타나는 승자와 패자의 문제를 해결하기 위해서는 승자의 혜택이 패자에서 파급되는 적하효과가 증진될 수 있도록 부문 간 연계효과를 높여야 한다. 동시에 사회이동성을 높일 수 있도록 사회복지정책을 통해 저소득층의 인적자원 형성을 지원해 나가야 할 것이다.

Best linear unbiased prediction (BLUP) has been used to estimate the fixed effects and random effects of complex traits. Traditionally, genomic relationship matrix-based (GRM) and random marker-based BLUP analyses are prevalent to estimatethe genetic values of complex traits. We used three methods: GRM-based prediction (G-BLUP), random marker-basedprediction using an identity matrix (so-called single-nucleotide polymorphism [SNP]-BLUP), and SNP-SNP variance-covariancematrix (so-called SNP-GBLUP). We used 35,675 SNPs and R package “rrBLUP” for the BLUP analysis. The SNP-SNP relationshipmatrix was calculated using the GRM and Sherman-Morrison-Woodbury lemma. The SNP-GBLUP result was very similar toG-BLUP in the prediction of genetic values. However, there were many discrepancies between SNP-BLUP and the other twoBLUPs. SNP-GBLUP has the merit to be able to predict genetic values through SNP effects.
中國 歷代 文獻에서 판다의 흔적 찾기(Ⅰ) ― 기존 연구 개괄과 貔貅說에 대한 분석을 중심으로

Though the panda certainly takes place as one of the main icons that represent China, it is surprisingly hard to find signs of the panda in traditional Chinese culture. In other words, from the ancient times to modern society, it is difficult to find traces of the panda in Chinese traditional documents, but even more difficult to interpret that the panda had a certain cultural status in China at the time. Midst the “panda boom” that initially started taking place from the start of the 20th century, the fact that the panda has low historical relevance in China is still triggering confusion within China. Hence, China eagerly set forth the research for the panda in historical documents, not only to acknowledge the panda in Chinese history, but also to prove that the panda was a significant part of Chinese culture. Through such endeavors, the names set forth for the panda in Chinese historical documents are these three. Through organization and analysis, this paper aims to demonstrate the logic and characteristic of such statement. Due to the limitation that such research has depth and broadness, the prior research and the Theory of Pixiu will be done in this paper, which will be later consecutively done in the next paper.
