It also will apply a recently proposed one-and-one-half-bound (OOHB) question format in order to obtain an appropriate welfare measure such as the mean WTP. To this end, the spike model suggested by Kristrom (1997) is adjusted and applied to modeling OOHB DC-CV data with zero WTP responses. The mean WTP per household was 2,716 Korean won per annum and the overall results show that the OOHB spike model outperforms the conventional OOHB model significantly.","PeriodicalId":278094,"journal":{"name":"KMI International Journal of Maritime Affairs and Fisheries","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128772706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We use a surplus production model based on the exponential growth model to estimate biological reference points. Fishing effort for the two gears is standardized and used in a general linear model. The Fox bioeconomic model is then used to estimate economic reference points. In the Korean hairtail fishery, the TAC assessment model for a single species and multiple gear types yielded values for each reference point that were more conservative.","PeriodicalId":278094,"journal":{"name":"KMI International Journal of Maritime Affairs and Fisheries","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122272864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is limiting the export of Mongolia's abundant resources at normal prices, and it is in the form of exploitation that can only be cheaply sold between Russia and China. However, due to the global warming, there is a possibility that Mongolia will be developed into a new maritime linked country by utilizing Arctic sea route and Russian inland waterway. Possible routes include the Selenga River in Northern Mongolia, Lake Baikal and Yenisei river-NSR in Russia. This study examined the status and the possibility of linking this route. In the past, Russia and Mongolia signed an agreement in 1925 to link the SelengaUlan-Ude-Baikal. One hundred years ago, when global warming was not in full swing, this agreement was intended to link the inland and land / shipping. Global warming may be an opportunity for the development of the region, with better conditions now underway in the commercialization of Arctic routes. Therefore, in order for Mongolia to leap as a maritime nation, the international complex logistics of the new Northern logistics market based on the development of East Siberia of Russia and the activation of the Arctic route, strengthens logistics linkage between Mongolia and Russia, and builds a complex logistics system, it is necessary to establish a system while carrying out a further research.","PeriodicalId":278094,"journal":{"name":"KMI International Journal of Maritime Affairs and Fisheries","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115136636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Asia is by far the top seawater mollusk producer on Earth, therefore, it is more necessary for it to be carried out related researches than the rest of the word. This analysis is an attempt to conduct a regional assessment of the direct economic impacts of ocean acidification on Asia’s mollusk mariculture. The results show that the accelerating ocean acidification poses increasing economic risks to the industry and the total financial losses vary with the degrees of ocean acidification, from 16.08 billion USD to 71.48 billion USD, from 42.66 billion to 189.61 billion USD, and from 121.11 billion USD to 498.28 billion USD, respectively, based on a discount rate of 2%, 3%, and 4%. In addition, we define a microeconomic model to illustrate how ocean acidification affects the mollusk industry’s economy. Considering that economic losses greatly depend on policy effects, it is safe to say that effective polices can reduce the negative impacts of ocean acidification and mitigate the risks of the sudden collapse of the industry as well as the resulting social problems.","PeriodicalId":278094,"journal":{"name":"KMI International Journal of Maritime Affairs and Fisheries","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121432773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A reliable prediction model is essential for the terminal operators to make decisions on planning and renovation of building structure and other port facilities. By monitoring the changes in seasonal patterns and business cycles in months or quarters, the predicted values help port managers in decision making and planning in the context of small and unexpected changes. In this paper, the authors reviewed a various of commonly used forecasting methods applied for the time-series data in the short-term. By applying a set of monthly data of Haiphong port from January 2003 to February 2019 to these models and evaluating forecast accuracy by root mean squared error (RMSE), we found that the Winters exponential smoothing method appears to be the best model for forecasting total cargo throughput with trend and seasonal variations. The empirical results could be used as a reliable scientific source for the port managers and the departments to make short-term plans for upgrading facilities and setting up effective loading and unloading plans, and then contribute to avoiding congestion and reducing unnecessary waste.","PeriodicalId":278094,"journal":{"name":"KMI International Journal of Maritime Affairs and Fisheries","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128445698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
