The study attempts to show that the theory of critical environmental variation quantum(CEVQ) has a sound logical basis and empirical support. It is well known that the theory of critical environmental variation quantum is derived from the theory of biological probability distibution function and the central limit theorem(CLT) in statistics. The study uses the case study of fisheries damages compensation caused br the public marine construction undertaken in the area do Anjeong Bay in the city of Tongyeong for empirical test of theory of CEVQ. The results shows that the CEVQ theory perfoms a good job in measuring quantatively fjsheries damages caused by outflow of cold water due to the operation of LNG company since 2002. Therefore the study proves that the CEVQ theory is a good theory having internal consistency and empirical applicability.

This paper examines the morphophonological variation of L-irregular verbs in Korean based on the empirical data collected through Internet search. The most common variation, Variant A, retains the stem 1 in more occasions than the standard dialect by not dropping the suffixal vowel I, while Variant B, the less frequent one, retains the 1 in all possible cases even by inserting the vowel L These variations are explained to result from a slight change in the same set of constraints. It is argued that variable rankings among three constraints in particular, i.e., 1-i, F(i), and F(1), bring about the variations. Also, the unequal frequency distribution among the three dialects seems to suggest that the rankings between these constraints are not discrete but rather continuous, along the line with Boersma and Hayes (2001).
