Coastal Zone is a integrated space including both coastal waters and inland. C.Z.M is a strategic practice system which can integrate and coordinate the coastal zone for preserving and making use of coastal resources. Through foreign and domestic C.Z.M Cases, this study analyzes the operating mechanism in the three aspects: role sharing among the administrative agencies, mediation and cooperation among the interested parties, and inducements of voluntary participation. And it achieves the common characteristics of C.Z.M: building the assessment system for establishing desirable policy directions, the stable support system for sustainable coastal management, the mediation system for cooperation of stakeholder, and the education system for reinforcing the management ability and inducing the voluntary participation. Finally it suggests the implications to build the coastal zone management system properly on the basis of common values in this mechanism.

This study researched the population of ecological characteristics of the goldeyes rockfish Sebasetes thompsoni sampled by gill net in the Ulleungdo area from February 2013 to February 2014 in order to assess the current stock status and provide scientific advice for management implementation. The instantaneous coefficient of total mortality (Z) was 0.78/year and the survival rate (S) was 0.459. The instantaneous coefficient of natural mortality (M) was 0.461/year. Based on the estimates of Z and M, the instantaneous coefficient of fishing mortality (F) was 0.318/year. The age at first capture ($t_c$) was 4.41/years. Current Yield-per-recruit (YPR) was 30.83 g, and fishing mortality at maximum YPR ($F_{max}$) and fishing mortality corresponding to 10% of the maximum slope in YPR curve ($F_{0.1}$) were 3.257/year and 0.673/year, respectively. $F_{35%}$ and $F_{40%}$, indicating fishing mortalities at 35% and 40% of maximum Spawning biomass-per-recruit (SBPR), were 0.619/year and 0.509/year, respectively. Based on the biological reference points, fishing mortality at overfished threshold yield ($F_{OTY}$) was calculated as 0.509/year. Current $SBPR/SBPR_{MSY}$ was 1.313 above 1.0, which means 'not overfishe,' while current $F/F_{OTY}$ was 0.629 below 1.0, which indicates 'not overfishing.' In conclusion, the current status of goldeyes rockfish was located in green zone (i.e., not overfished and not overfishing) according to the revised Kobe plot.
