Marine protected Areas(MPAs) are specially designated zones of the sea that are designed to secure operation of ecosystem function and to restore marine ecosystem to the original state by excluding all detrimental human activities. MPAs have been proposed in many countries as means of realizing sustainable fisheries and recently MPAs are newly receiving attention as precautionary measure for global warming and climate change. The purpose of this paper is to examine the possibility of MPAs as fisheries management tools through a wide range of literature analysis and to suggest necessity of fisheries purpose of MPAs in Korea. Establishment of marine protected area can accompany various economic benefits such as restoration of marine environment, preservation of habitats, promotion of marine tourism and so on. Especially, a lot of case studies suggested that MPAs may bring out benefits to the fishing industry as a result of enhanced stocks. Fisheries benefits of MPAs on targeted species include increased abundance, increased mean individual size and age, increased reproductive output, enhanced recruitment inside and outside refuge, maintenance of genetic diversity of stocks, and enhanced fishery yields in adjacent fishing grounds, so called spill-over. MPAs for ecosystem conservation and protection of coastal wetland have been applied appropriately and effectively, however, the Korean MPAs system is still detective due to absence of fisheries purpose MPAs. Finally, suggestions for Korean MPAs can be summarized as following four recommendations; to establish number of small-scale MPAs rather than few large MPAs, to designate island and its surrounding areas as reserve, to consider MPA design with stock enhancement program, and to undertake co-management with Eochon-Gye, the traditional coastal community in Korea.

In 2014, fishes caught using stow nets in coastal waters off Gochang from May to October were assessed for appearance patterns. The fishes were caught at four research stations (St.) and were found to comprise 37 species, 18 families, and 7 orders. The dominant species were Thryssa kammalensis, Setipinna tenuifilis, and Sardinella zunasi. To gain a measure of their biodiversity, all species were assessed for their number, richness, diversity, evenness, and dominance. The highest and lowest numbers of total fishes caught were recorded in September (4,819 individuals) and October (828 individuals), respectively. The diversity was the highest in October (H' = 2.478) and lowest in June (H' = 0.880). The evenness index was the highest in October (E = 0.780) and lowest in June (E = 0.343). The richness index was the highest in October (R = 3.424) and lowest in May (R = 1.552). Finally, the dominance index was the highest in June (D = 86.2%) and lowest in October (D = 40.3%).

Laver aquaculture, which occupies a large proportion in the aquaculture industry in Korea, is still highly dependent on human labor. Therefore, it is necessary to study the development of an automatic system to improve the working environment and increase the efficiency of aquaculture production systems. The purpose of this study is to evaluate the economic feasibility of an improved system in a study for the loading-unloading and automatic weighing systems in laver aquaculture industry. Economic analysis of the developed unloading and automatic weighing system were implemented under various conditions to calculate more accurate benefits and costs. As a result of this study, the economic feasibility was found to be very high in the three models: net present value (NPV), benefit-cost ratio (B/C), internal rate of return (IRR). Moreover, the results of sensitivity analysis showed that the economical efficiency of the automatic loading, unloading, and weighing system in laver aquaculture was very high.

This study was to analyze amenity of the port landscapes for North port, South port, and Gamcheon port in Busan. Amenity related variables came from Semantic Differential(SD) method and then were conducted by the factor analysis. Multiple regression was done for the relationship between the amenity and factors. The result found 3 factors, including dynamics, stability, and familarity. Much importance was placed on dynamics among them. Therefore, building port landscapes and their image attracting tourists should consider dynamics in terms of port landscape plan and tourist attraction development for amenity quality management.

Recreation specialization and consumptive orientation are two important constructs to understand anglers' attitudes and behaviors. Although theoretical explanations and previous studies in different countries addressed the relationships between the two constructs, limited support has been provided in a context of anglers in Korea. This study developed a conceptual model explaining the causal relationships between recreation specialization, anglers' preferences (activity-specific and activity-general) and consumptive orientation. An on-site survey was conducted to anglers in the city of Busan and Gyeongnam province in 2018. A total of 614 data were analyzed using Structural Equation Modeling The study results showed that recreation specialization positively and indirectly influenced consumptive orientation via anglers' activity-specific and activity-general preferences. Theoretical and practical implications are further discussed.

This study investigated changes in the quality and antioxidant activity of soy sauce with added Saccharina japonica powder (FSP). Soy sauce was prepared with acid-hydrolyzed soy sauce, brewed soy sauce, honey, ginger, garlic, dried red pepper, ${\gamma}$-aminobutyric acid (GABA)-enriched sea tangle fermented in lactic acid, and 1% or 3% S. japonica powder by soy sauce volume. The color, pH, microbiology, amino nitrogen, free amino acids, antioxidant activity, and sensory qualities of the soy sauce were evaluated. There were no significant differences in the general characteristics or antioxidant activity. However, the addition of FSP to the soy sauce enhanced the delicate flavor. Furthermore, soy sauce containing FSP had higher levels of GABA (50 mg/100 mL), a biofunctional ingredient. Therefore, the development of seasoning soy sauce with enhanced functionality seems possible.

The purpose of this study was to conduct a comparative study between Korea and the United States to examine anglers' motivations, consumptive orientation, and the relationship between these two concepts. The following two research questions were explored: (1) whether there are significant differences in anglers' motivations and consumptive orientation between Korea and the United States; and (2) what differences exist in the effects of anglers' motivations on consumptive orientation between these two countries. The main research results are as follows. First, Korean anglers showed a higher level of consumptive orientation than American anglers. Second, a positive relationship between activity-general motivation and consumptive orientation was reported for Korean anglers while the relationship was opposite for American anglers. Study results imply that national angler surveys as well as public education and outreach programs are necessary to help anglers engage in sustainable fishing behaviors for effective fishery resources management.

The maritime industry has emerged as a new growth engine. The municipalities that own the port are trying to add value through the maritime industry. Overseas port cities are also creating maritime industrial clusters to generate profits and strengthen competitiveness. Therefore, it is very important to understand the comparative status of the domestic maritime industry by region. Based on this analysis, it is possible to establish maritime industrial clusters and strategies for integration. This study analyzed the structure of the maritime industry located in Jeollanamdo province, the southwestern part of Korea. Through the analysis of existing literature, the maritime industry was reclassified into 5 major categories, 21 subcategories, and 84 subcategories. Based on the reclassified maritime industry, the analysis of the Jeollanamdo province maritime industry was based on applying the location quotient and the shift-share analysis. As a result of analyzing the geographical location of Jeollanamdo province, other industries showed the highest value of 2.790, followed by fisheries (2.227), shipbuilding industry (1.164) and marine tourism industry (0.554). The growth effect of the maritime industry in Jeollanamdo province was 35,323 people, and net growth effect excluding national growth effect was 11,945 people. In particular, the net growth effect of the shipbuilding industry was the highest at 11,320, followed by shipping logistics (6,371) and marine tourism (1,529). On the other hand, there was no net growth effect in fisheries. The results of this study can be used as basic data for the construction of the maritime industrial cluster for Jellanamdo province in the future.

Ecotourism as a alternative tourism destination has to adapt to current market mechanisms, which is becoming extremely competitive and which are dominated by communication and promotion strategies and techniques. We need to know the causative factors and influences by which tourists are motivated to become included in various market segments. The primary purpose of this study is to segment and profile the motivations of ecotourist, so as to enable a better understanding of ecotourism in Korea. A self-administered survey was collected from 200 tourists in the study area. A factor-clustering method identified four distinct segments: want-it-all seeker, passive seeker, aesthetic seeker, value sharing seeker. We conclude by considering the relevant of our findings to ongoing discussions of ecotourists' market segmentation.
