Tensor Product 에 있어서의 semi-exact
이인석,배철곤,민강주 한국수학교육학회 1973 수학교육 Vol.12 No.1
In this paper, we want to verify some properties in tensor product. It is interesting to think semi-exact sequence in tensor product by [3]. Moreover no hardness is there in process and we want to discuss the commutativity in tensor product. For a certain semi-exact sequence, if we product arbitrary Abelian group for each group then the tensor product will do or not. Here, we have positive answer. At first we define the semi-exact sequence as following.
Network approaches to the genetic dissection of phenotypes in animals and humans
이인석 한국통합생물학회 2013 Animal cells and systems Vol.17 No.2
Various genome-wide approaches to identifying the genetic components that underlie phenotypes in animals and humans have been developed during the last several decades. The relationship between gene and phenotype, however,cannot be represented by a simple one-to-one correspondence. Rather, many genes are typically related to a single phenotype and many phenotypes can be associated with a single gene, a major theme within the study of complex phenotypes. Therefore, to dissect the genetics of complex phenotypes, one must not only identify the genetic components involved but also the relationships between genes. To fulfill this new goal in modern genetics, the field of network science has recently tackled the complexity of phenotypes. There are various types of gene networks, which are defined by their differential representation of network edges (i.e., relationships). Different networks map physical,genetic, functional, and regulatory interactions between genes. Gene networks can be constructed using a wide variety of experimental and computational methods, which provide complimentary information about the genetic organization of phenotypes. The predictive power of a gene network is further augmented via integration with functional genomics or genetics data, including expression, loss-of-function, or chromosomal interval or nucleotide position data associated with a phenotype. Although the field of network-based genetics has made phenomenal progress during the last decade, many limitations, such as the completeness and dynamicity of gene networks, must still be overcome.

A survey was carried out to understand and analyze the characteristics of the symptoms of musculoskeletal disorders among farmers of pears, grapes, cucumbers, eggplants and various vegetables. One hundred and forty farmers participated in the study. It was found that task characteristics differ according to crops and the gender of the farmers. The fruits farmers mainly assume arm-elevated postures while vegetables farmers mostly take bent-back or squatting postures. The symptoms of musculoskeletal disorders are mostly reported in the low back, shoulder, and knee. Though the rates of symptoms of musculoskeletal disorders were not much different among the crops, the fruits farmers showed relatively higher rate of symptoms in the shoulder and neck than those of other crops. The rate of symptoms of female farmers was higher than that of male farmers, which is the similar results of other studies. The relatively low correlationship between the task characteristics and the rate of symptomes might be caused by the fact that most farmers are involved in various agricultural tasks that are not much different among different crops

Glucocorticoid-remediable aldosteronism (GRA) is an autosomal-dominant inheritable form of hyperaldosteronism with early onset hypertension. GRA is caused by unequal crossing-over of the steroid 11β-hydroxylase (CYP11B1) and aldosterone synthase (CYP11B2)genes. As a result of chimeric gene duplication, aldosterone is ectopically synthesized in the adrenal zona fasciculata under the control of adrenocorticotropin. Here, we describe three cases of GRA in a Korean family. The proband-a 21-yr-old female-was incidentally found to have high blood pressure (170/108 mmHg). Her 46-yr-old father had been treated twice for cerebral hemorrhage at the ages of 29 and 39 yr. Her 15-yr-old brother had a 2-yr history of hypertension; however, he was never treated. Their laboratory test results showed normokalemia, hyporeninemia, hyperaldosteronism, and a high plasma aldosterone concentration-to-plasma renin activity ratio. Normal saline loading failed to suppress aldosterone secretion. However, dexamethasone administration effectively suppressed their plasma aldosterone concentrations. Following genetic analyses with PCR and direct sequencing to document the chimeric gene and crossover site, respectively, we identified CYP11B1/CYP11B2 and determined the breakpoint of unequal crossover to be located between intron 2 of CYP11B1 and exon 3 of CYP11B2.
