본 연구의 목적은 국가중요농어업유산의 등재 준비 단계부터 사후 관리까지 적용이 가능한 경관 평가 지표를 도출하는 것이다. 이를 위하여 전문가들을 대상으로 델파이 조사를 실시하였으며, 2014년 8월부터 11월까지 1차 개방형, 2차 개방형, 3차 폐쇄형으로 진행하였고, 1차 28명, 2차 25명, 3차 29명의 전문가 의견을 연구에 활용하였다. 그 결과, 농어업유산의 경관 평가 지표는 평가영역 5개, 평가항목 10개, 평가지표 40개로 구성되었다. 평가영역은 향토성, 진정성, 심미성, 관광잠재력, 지역성이었고, 향토성은 농어촌성과 향수성, 진정성은 객관적 진정성과 실존적 진정성, 심미성은 매력성과 조화성, 관광잠재력은 자원가치성과 활용가치성, 지역성은 물리적 고유성과 문화적 정체성으로 분류되었다. 본 연구를 통하여 도출된 시사점은 첫째, 농어업유산의 경관의 질을 평가할 때에는 유산으로서의 가치를 고려해야 한다는 점에서 일반 농어업 경관 평가 준거를 그대로 준용할 수 없음이 규명되었다. 둘째 기존의 농어업 경관에서 주목하고 있는 물리적 요인뿐 아니라, 정서적 요인을 중시하고 있었고, 주민이 농어업활동이나 축제 체험 등 행사에 참여하는 일상적이거나 일시적인 액티비티를 경관 평가 항목으로 포함하고 있다는 점에서 기존의 경관 평가 지표에서보다 확장된 경관 개념을 포함하였다. 셋째, 농어업유산은 그 순간 경작지에서 보이는 공시적 관점뿐 아니라, 눈에 보이지 않는 시간까지 포함한 통시적 관점을 포함한다는 관점에서 주민들의 삶에 주목하게 되고, 따라서 경작지와 자연환경은 물론이고, 마을경관 특히 주거지와의 관계성에 의미를 두고 있음을 알 수 있었다. 끝으로 농어업유산의 핵심 요소인 유산적 가치 측면과 관광적 활용 측면이 모두 반영되었고, 생산경관과 관련된 특산물 판매장의 사고파는 활동을 포함한 일시적이고 동태적인 경관들이 지표로서 도출되었다는 점에서 차별화되었다. 그러나 본 연구는 각 항목 간의 가중치가 도출되지 않아, 상대적 중요도를 알 수 없고, 경관의 총점을 비교할 수 없다는 한계점이 있으므로 이에 대한 연구가 후행되어야 할 것이다.

Cold storage warehouse industry in Japan has been extended in its scale in terms of both the number of storages and cold storage capacity in order to meet the extended reproduction of the marine products industry. However, increasing total amount of the stored goods since mid 80s led to relative decrease of marine products while the number of storages was remained the same or decreased, though cold storage capacity was gradually increased and is maintained the increase of the average cold storage capacity. As structural change in the cold storage warehouse industry emerges, cold storage warehouses require new approach to individual storage management with 1)diversity of the stored goods; 2) more competition due to increase of the cold storage capacity; and 3) sizing of the average cold storage capacity. Therefore, this study analyzed how cold storage warehouse management activity with individual storage sizing changes; and significance of sizing and functional change in cold storage warehouses experiencing sizing, by observing leading cold storage warehouse industry of the metropolitan area in Japan. In conclusion, reorganization of cold storage warehouse industry in the metropolitan area in Japan can be summarized as follows: First, competition among cold storage warehouses in the metropolitan area in Japan is not simply limited to storage industry but extended to establishment and securing physical distribution function. Second, since cold storage warehouse industry is in Scrap & Build phase, decision of management executives on whether taking direction to maintain/continue enhancement of physical distribution function may cause drastic reorganization in the cold storage warehouse industry, Third, since profit of physical distribution management based on cold storage warehouses is insignificant, it is not easy to accomplish expected management outcome, Fourth, today's cold storage warehouse industry mainly characterized by diversity of the stored goods needs facility reorganization with comprehensive and functional integration covering from F class cold storage capacity to F&C class.

The Korean government has been carrying out the marine ranch development project since 1998 with the purpose of responding to the decrease in coastal fishery resources and fishery income, preparing a systematic management system for the sustainable use of fishery resources and realizing advanced fisheries power by expanding and upgrading fisheries resource development projects. In addition, the government established the Korea Fisheries Resources Agency and promoted projects for the protection and management of fishery resources by increasing basic productivity by artificially creating marine forests in areas where whitening events occur. Since the project of building marine ranches and marine forests requires immense government financial support, it is important to estimate the economic value and thoroughly evaluate the feasibility of the project. In this paper, the project of non-market economic value of the development of marine ranches and the development of marine forests was estimated. CVM (Contingent Valuation Method) was applied as a methodology for benefits estimation. Prior to the analysis, a one-on-one interview survey was conducted with participation of 512 residents and 514 residents respectively for the project of creating a marine ranch and developing a marine forest. A DBDC (Double-Bounded Dichotumous Choice) model was applied in the WTP (Willingness To Pay) analysis model and the socioeconomic variables of the surveyor, such as sex, age, education and income, were reflected in the model. The economic benefits from the two projects, namely, building of marine ranches and developing marine forests were estimated to be equal to 4,608 won and 7,772 won per household per year, respectively. According to the results of the survey, it seems that respondents think that marine forests are more valuable than marine ranches. This is as a result of ordinary citizens' thought that the marine ranches are more cost-effective than the marine forests. The benefits estimated through this study can be used for analysis of economic feasibility prior to carrying out the project of building marine ranches and developing marine forests, and are considered to be the valuable for policy-making purposes and finding social and economic consensus.

Many studies to cope with the present problems of Korean coastal and offshore fisheries has been performed, but these were done partly in necessities and general studies for Korean inshore and offshore fisheries are in early stage. Most of these studies adopted analytical way of approach for each fishery individually and they could not reflect the effect of correlated interaction among fisheries on the several common species/stocks, and thus optimal effort allocation was impossible. To consider general fisheries and optimal effort allocation among competing mixed species, a linear programming (LP) approach is applied in this study and introduced into 16 important inshore and offshore fisheries with 13 constraining species which were chosen by annual yield order. This study is not based on the biological interaction among species (i.e., prey - predator system) but the technological interaction between species and fishing efforts. For the application of LP model in these fisheries, the standardization of fishing efforts through different fishing gears could not be successful and a new way of effort standardization through CPUE for vessel tonnage was originated. Total standardized fishing effort on a particular species i, Ei, is computed as the linear summation of standardized fishing effort generated by each fishery j. That is, (equation omitted) where $f_{j}$ is the total vessel tonnage of fishery j and aij is the coefficients contributing to the standardized fishing effort per ton for species i taken in fishery j. The total fishing effort level on species i due to both directed fishing and by - catch can thus be accounted in the aij's. Optimal effort allocation among the j fisheries may be considered a minimizing problem (minimize $\Sigma$ $f_{j}$), subject to the constraints that standardized fishing effort levels on particular species are maintained at, above, and below certain predefined levels. Fishing effort goals for individual species can be based on various biological and/or economic criteria, i.e., fishing effort level generating maximum sustainable yield and/or maximum economic yield. But in this study the $F_{0.1}$ criteria which was accepted as an approximate level for $F_{mey}$ by Outland and Boerema's (1973) study. The findings of this study are, (1) LP model can be applied to the Korean inshore and offshore fisheries giobally. (2) Through a new way of combining multiple different fisheries' efforts for a particular species together generating standardized fishing effort, Schaefer curve could be applied to the complex system successfully. (3) The results of this study for total reduction scale were mostly the same as those of prior studies, but different much from the individual scales of reduction. This study showed the necessities for exploitation of more concrete parameters to put into consideration of profitability of fisheries and social factors, and this model can be modified according to the actual constraints. Also, considering the age structure of stocks, this model can be developed into better one for better fisheries management.ent.

최근 국제적으로 수산부문에 대한 현안문제 중의 하나는 어업에 있어 어획능력 (fishing capacity)을 감축시키고자 하는 것이다. 이는 어획능력이 크게 증강되어 어업자원에 대한 어획압력이 증가하여 자원남획을 초래하고 있을 뿐만 아니라 추가적인 비용이 소모되므로 지속 가능하고 경영안정적인 어업발전을 위해서는 과잉된 어획능력의 감축이 시급하기 때문이다. 더욱이 1999년에는 세계식량농업기구(FAO)가 '어획능력 관리를 위한 국제적 행동계획'을 채택하고, 각국으로 하여금 어업별 어획능력 측정과 과잉 어획 능력 감축을 위한 관리방안 마련을 촉구하였다. 본 연구에서는 1978년~2003년간의 어획량과 어획노력량(어선척수, 톤수, 마력수, 그리고 조업일수) 자료를 이용한 자료포락분석(DEA) 기법으로 우리나라 대형선망어업의 연도별 어획능력 변화를 측정해 보았다. 분석 결과, 2003년도의 경우 대형선망어업의 어획능력 활용도가 약 50% 수준으로 나타나 유휴 어획능력이 존재하는 것으로 평가되었다. 그리고 과잉 어획능력 감축 수준을 파악하기 위한 민감도 분석 결과 2003년도 어획량을 유지하기 위해서는 어선척수(마력수와 톤수 포함)를 50% 정도 삭감하든가 아님 조업일수를 약 63% 정도 줄여야 하는 것으로 나타났다. 또한 대형선망어업의 최대 지속적 어획량(MSY) 수준을 유지하기 위해서는 어선척수(톤수와 마력수 포함)에 대한 30% 삭감이나 조업일수의 약 60% 감소가 필요한 것으로 분석되었다.

We analyzed annual and seasonal variations in fish species composition and distribution patterns using both daily catch and quantitative analysis data collected from a set-net fishery over a period of two years (2011-2012) on the coast of Dapo, Geoje Island. Set-net fishing season in this area is from May to November, and the annual yield based on the daily catch data was 171,412 kg in 2011, and 102,611 kg in 2012. In total, there were 46 species (belonging to 36 families and 12 orders) in 2011, and 41 species (belonging to 25 families and 9 orders) in 2012. The dominant species in terms of numbers were Trachurus japonicus, Engraulis japonicus, Clupea pallasii, Scomber japonicus, and Sphyraena pinguis. The range in fork length for T. japonicus and E. japonicus was from 3.2 to 23.9 cm, and from 2.6 to 13.3 cm, respectively. The fork length of recruiting juveniles to the Dapo set-net fishing ground ranged from 4.6 to 7.8 cm (median) for T. japonicus, and from 4.1 to 5.0 cm (median) for E. japonicus. The fact that most of the fish caught from the two species were at immature growth stages implies that the coast of Dapo can act as a nursery area for these migratory species.

This study aimed to examine the applicability of a portfolio approach to the ecosystem-based fisheries management targeting the large purse seine fishery. Most fisheries are targeting multispecies and species are biologically and technically interacted each other. It enables a portfolio approach to be applied to find optimal production of each species through expected returns and risk analyses. Under specific assumptions on the harvest quota by species, efficient risk-return frontiers were generated and they showed a combination of optimal production level. Comparisons between portfolio and actual production provided a useful information for targeting strategy and management. Results also showed the possibility of effective multispecies fisheries management by imposing constraints on each species such as total allowable catch quotas.
