Business sentiment among Korean firms has worsened... mainly due to fewer working days in February as it overlapped with the Lunar New Year holiday.<br /> The Bank of Korea says its business sentiment index or B-S-I among overall industries edged down one point from the previous month to 77.<br />It also cited a steep decline among manufacturers particularly in the shipbuilding and automobiles sectors... that dropped two points from the previous month to 75... the lowest level since January last year.<br />A reading below 100 means there are more pessimists than optimists about the economy. <br />
