To elucidate the distribution of halophytes in Korea, we surveyed 95 coastal salt marsh and sand dune areas. As a result, 62 halophytes of 57 species, 4 varieties and 1 form belonging to 44 genera and 21 families were recorded from coastal regions and islands of South Korea. Of these, 33 taxa were plants growing on sand dunes and the other 29 in salt marsh. Fifty eight taxa were found on the west coast, which was surveyed at 61 areas. The most common species among them were Suaeda glauca (Bunge) Bunge, Suaeda japonica Makino, Phragmites communis Trin., Zoysia sinica Hance, Carex scabrifolia Steud. in salt marsh, and Salsola komarrovii Iljin, Lathyrus japonicus Willd., Limonium tetragonum (Thunb.) A.A. Bulloc, Calystegia soldanella Roem. & Schult. on sand dunes. On the other hand, only 45 taxa were found on the southern coast, surveyed at 15 areas. On the east coast, surveyed at 13 areas, 44 taxa were found. The most common species were Salsola komarrovii Iljin, Lathyrus japonicus Willd., Calystegia soldanella Roem. & Schult., on sand dunes and Linaria japonica Miq., which on the Korean peninsula is found only on the east coast. On Jeju Island, surveyed at 6 areas, 30 taxa of halophytes were found. Canavalia lineata (Thunb.) DC. is found in Korea only on Jeju Island. About half of the Korean halophytes were members of three families (Chenopodiaceae: 12 species, Poaceae: 12 species and Asteraceae: 7 species).

Objectives : The purpose of this study was to analyze the relationship between the Cold-pattern and the quantitative index through the results of an anthropometric method and Bio Impedance Analysis (BIA) of the Haenyeo living in Jeju island. Furthermore, we will examine the effect of Cold-pattern on the quality of life. Methods : BIA indices were acquired directly from Inbody770 and questionnaires were collected by Gallup Korea professional surveyor through face to face interviews. Binary regression analysis and linear regression analysis were used to examine the association between collected data. Results : Total of 175 of people were participated in this study. First, we examined the difference of the indicators in the Cold-pattern group and the non-Cold pattern group by the average comparison of the anthropometry and BIA indices. Most of the non-Cold pattern group showed high quality of life, BIA and anthropometry. In the relationship between Cold-pattern and anthropometry and BIA indices, BMI and PA indices were found to affect the Cold-pattern on a group basis. As the BMI increased by $1kg/m^2$, probability of not being non-Cold pattern was 1.13 times. and as the PA increased by $1^{\circ}$, probability of not being non-Cold pattern was 2.4 times. In the case of EQ5D value, the quality of life of ${\beta}$ was increased by 0.08 in non-Cold pattern (p <.05), EQ5D VAS of ${\beta}$ was also increased by 10.05 (p <.05). Conclusions : This study showed that BMI and PA could be used as a clinical index to evaluate the Cold-pattern as a clinical indicator, and there is a difference in quality of life according to Cold-pattern.

We studied the management policy for Haliotis diversicolor fisheries in the coastal area of Sungsanpo using Yield-per-recruit model from 2004 to 2006. The age at first capture($t_c$) and fishing mortality(F) annually estimated during the study period decreased and increased, respectively. The maximum yield-per-recruit in 2004 was increased by increasing $t_c$ from the 2.012 year of current $t_c$ to 2.7 year or increasing F from the 0.574/year of current F to 0.800/year, and that in 2005 was increased by increasing $t_c$ from the 1.946 year of current $t_c$ to 2.5 year or increasing F from the 0.578/year of current F to 0.880/year. In 2006, the maximum yield-per-recruit was increased by increasing $t_c$ from the 1.926year of current $t_c$ to 3.1 year or decreasing F from the 1.088/year of current F to 0.810/year. Further, although the current F in 2004 and 2005 was lower than the estimated $F_{MAX}$, that in 2006 was higher than the estimated $F_{MAX}$. These results indicate that the likelihood of growth overfishing with increasing catch of smaller H. diversicolor in 2006 was greater than in 2004 and 2005. As action that could prevent growth overfishing in fisheries management of H. diversicolor, increasing for the current $t_c$ could be a more appropriate policy because the artificial decrease of the number of woman divers related F is actually difficult.
