Base on the survey and financial statement on fish-paste processing company, this study aimed to estimate management efficiencies of fish-paste processing management using a data envelopment-analysis (DEA), In-depth interview and to find out their determinants. Model results show that the estimated mean management efficiencies obtained for the VRS and CRS DEA are 83.7% and 89.1%. In-depth interview results also show that efficiencies caused by scale of technical matter was greater than efficiencies caused by the scale of the company. Thus it implies that technical development is essential for achieving high-efficiency of fish-paste processing company more than expanding the size of company.

Jeong, Hyeongseok. 2018. “Discursive Functions of the Free Morpheme ish1)”. The Sociolinguistic Journal of Korea 26(2). 37~62. This study aims to explore the corpus data of the free morpheme ish with special reference to its discursive functions. Derived from suffix -ish, ish develops as a free morpheme denoting a sense of approximation. On its way to broadening its functions, ish not only approximates the propositional meaning, but also hedges the speaker's attitude towards the proposition. The semantics of ish indicates that the degree is slightly below the standard, but data show that this is not always the case. Contextual factors play a part in determining the degree of ish. By thoroughly analyzing data from the corpora, I focus on the functions of the ish in the discourse level, and the role of the surrounding context in differing scale of the free morpheme ish. Moreover, I introduce the punctuation marks occurring with the use of ish in written examples by focusing on the characteristics of each punctuation mark.
