Seasonal Occurrence of Aphids (Aulacorthum solani, K., Aphis glycines M.) and Effects of Some Insecticides on Aphids with Infurrow Treatment in Soybean
No full textThis study was conducted to investigate the seasonal occurrence of aphids and to evaluate efficacy of Carbofuran, Disulfoton and Ortran applied infurrow at the planting time in the field for the control of some aphids on soybean in 1976. Foxglove aphids (Aulacorthum solani) and soybean aphids (Aphis glycines) were dominant species in the soybean field and there were two peaks in the year. The occurrence patterns of aphids were different between visual counting on leaves and in yellow-pans. Carbofuran and Disulfoton showed a good effect for the control of aphids but Ortran was less effectiveOriginating text in Korean.Citation: Hwang, C. Y., Uhm, K. B., Choi, K. M. (1981).

Operational Interpretation of the Choi Rank Through k-State Exclusion
No full textThe Choi-state is an indispensable tool in the study and analysis of quantum
channels. Considering a channel in terms of its associated Choi-state can
greatly simplify problems. It also offers an alternative approach to the
characterisation of a channel, with properties of the Choi-state providing
novel insight into a channel's behaviour. The rank of a Choi-state, termed the
Choi-rank, has proven to be an important characterising property, and here, its
significance is further elucidated through an operational interpretation. The
Choi-rank is shown to provide a universal bound on how successfully two agents,
Alice and Bob, can perform an entanglement-assisted exclusion task. The task
can be considered an extension of super-dense coding, where Bob can only output
information about Alice's encoded bit-string with certainty. Conclusive state
exclusion, in place of state discrimination, is therefore considered at the
culmination of the super-dense coding protocol. In order to prove this result,
a necessary condition for conclusive k-state exclusion of a set of states is
presented in order to achieve this result, and the notions of weak and strong
exclusion are introduced.Comment: 6 + 3 pages, 2 figure
Introduction: Why fandom matters to the international rise of K-pop
No full textThis chapter shows how Korean dramas in Latin America have piqued cultural interest in Korea as a whole, and paved the way for the influx of K-pop. It explains that Japanese popular cultures have been a powerful intermediary for the "chemistry" between K-pop and Latin American youth. The chapter explores a conceptual discussion on how K-pop gets acclimatised to Latin American cultural milieus. Korean dramas have continued to attract young and middle-aged female audiences in Latin America. The K-pop industry, too, has long been a "tenant" in the cluttered edifice of Korean dramas. While sound effects are rarely engaged in dramas, an excessive dosage of background and theme songs tend to saturate the whole stretch of a programme's running time. K-pop cover dance was later repurposed into a bridgehead to expand the global foothold of K-pop by Korean broadcasting networks hand in hand with para-state bureaus
Choi matrices revisited. II
No full textIn this paper, we consider all possible variants of Choi matrices of linear
maps, and show that they are determined by non-degenerate bilinear forms on the
domain space. We will do this in the setting of finite dimensional vector
spaces. In case of matrix algebras, we characterize all variants of Choi
matrices which retain the usual correspondences between -superpositivity and
Schmidt number as well as -positivity and -block-positivity. We
also compare de Pillis' definition [Pacific J. Math. 23 (1967), 129--137] and
Choi's definition [Linear Alg. Appl. 10 (1975), 285--290], which arise from
different bilinear forms.Comment: 17 pages; the comma in the title has been replaced to a period; to

Genetic and expression alterations in association with the sarcomatous change of cholangiocarcinoma cells
No full textCholangiocarcinoma (CC) is an intrahepatic bile duct carcinoma with a high mortality rate and a poor prognosis. Sarcomatous change/epithelial mesenchymal transition (EMT) of CC frequently leads to aggressive intrahepatic spread and metastasis. The aim of this study was to identify the genetic alterations and gene expression pattern that might be associated with the sarcomatous change in CC. Previously, we established 4 human CC cell lines (SCK, JCK1, Cho-CK, and Choi-CK). In the present study, we characterized a typical sarcomatoid phenotype of SCK, and classified the other cell lines according to tumor cell differentiation (a poorly differentiated JCK, a moderately differentiated Cho-CK, and a well differentiated Choi-CK cells), both morphologically and immunocytologically. We further analyzed the genetic alterations of two tumor suppressor genes (p53 and FHIT) and the expression of Fas/FasL gene, well known CC-related receptor and its ligand, in these four CC cell lines. The deletion mutation of p53 was found in the sarcomatoid SCK cells. These cells expressed much less Fas/FasL mRNAs than did the other ordinary CC cells. We further characterize the gene expression pattern that is involved in the sarcomatous progression of CC, using cDNA microarrays that contained 18,688 genes. Comparison of the expression patterns between the sarcomatoid SCK cells and the differentiated Choi-CK cells enabled us to identify 260 genes and 247 genes that were significantly over-expressed and under-expressed, respectively. Northern blotting of the 14 randomly selected genes verified the microarray data, including the differential expressions of the LGALS1, TGFBI, CES1, LDHB, UCHL1, ASPH, VDAC1, VIL2, CCND2, S100P, CALB1, MAL2, GPX1, and ANXA8 mRNAs. Immunohistochemistry also revealed in part the differential expressions of these gene proteins. These results suggest that those genetic and gene expression alterations may be relevant to the sarcomatous change/EMT in CC cells.open113031sciescopuskc
