This study aims to examine current status of cultural products in Mokpo city and their problems and develop cultural products design suitable to this situation. Cultural products in Mokpo sold here are made from China and have lower quality or traditional crafts and folkcrafts which can be purchased anywhere in Korea and they are not enough to show identity or image of Mokpo city. So I mixed the logos of 'mokpo city' and 'national maritime museum' based on main motive of 'modern Korean ship and shipbuilding tools' held by 'National Maritime Museum' and 'Goebukseon (turtle ship)' and 'Hanseon' which are suitable to the image of maritime culture as cultural products advocated by Mokpo city and developed one design style for print. This design is applied to T-shirts, necktie, cap, cushion and mug. Silk print, transfer print and needlework techniques are applied to each item and the whole cultural products have design of set concept. It is a case of applying modern product marketing technique to our cultural products not a design for only one item, is aimed to recreate spiritual and cultural value that a region has as daily goods to be used by general consumers and show the chance and possibility to complement shortcomings of existing cultural products and develop traditional culture having locality.

In this study, samples were collected from various ancient wooden shipwrecks, including the Shinan shipwreck and Jindo shipwreck that used iron nails, the Yeongheungdo shipwreck carrying iron artifacts, as well as the Sibidongpado shipwreck and Wando shipwreck where degradation products were not observed, all of which were salvaged by the National Research Institute of Maritime Heritage. The aim was to analyze the characteristics of degradation products generated by iron (Fe) within the salvaged wooden shipwreck materials and establish fundamental data on degradation products in waterlogged archaeological wood. The analysis revealed that sulfur (S) is generally accumulated in wood obtained from marine environments. It was observed that the content of inorganic substances such as iron and sulfur was significantly higher in the Shinan shipwreck, Jindo shipwreck, and Yeongheungdo shipwreck compared to Sibidongpado shipwreck and Wando shipwreck, which used wooden nails. This indicates that the presence of iron affects the accumulation of degradation products and suggests that iron is a factor in the corrosion of wood. Furthermore, crystallin compounds were observed within the cell walls, and higher concentrations of iron and sulfur were found in the resin ducts, rays, and radial tissues. This suggests that during desalination and consolidation treatments, warm water or polyethylene glycol (PEG) may move degradation factors into resincanals, rays, radial tissues, etc.

This study investigated the effects of imported fisheries products on WTO/DDA tariff negotiations. To calculate the results, the study estimated the demand functions of imported fisheries products by using unit root and cointegration approaches. These approaches allowed us to solve spurious regression problems with macro-economic variables. In addition, this study surmised the effects of change by individually imported fish products from a tariff negotiation model using price elasticities of estimated import demand function. In a process of the analysis for estimating import effects, this study found out that 39 out of 128 imported fish products had positive (+) price elasticities or did not exhibit cointegrations. To cure this problem, this study suggested that the effects of these 39 imported products be estimated with the average variation rate of import volume, rather than by the Ordinary Least Squares approach. In this study, a case-study of tariff formula with coefficient 8 based on a 'Swiss formula' for priority duty rate of 2001 and 2008 was used by to analyze the effect of change in the 128 imported fish products of both years, respectively.

Four compounds were isolated from Suaeda japonica by repeated column chromatography. Their structures were identified as 2'-hydroxy-6,7-methylenedioxy-isoflavone (1), loliolide (2), dehydrovomifoliol (3), and uridine (4) by spectral analysis and comparison with the published data. All compounds were isolated for the first time from this plant.

The study aims to identify the generation and treatment of fishery by-products in Korea and suggests future directions and strategies for their eco-friendly utilization and industrialization. First, the study focuses on the identification of the generation and their treatment in Korea since merely few study were conducted and they did not provide enough information regarding the overall generation and treatment at the national level. According to the estimation, Korea generates 800 thousand to 1,200 thousand tones of fishery by-product every year. The fishery by-products generated at large seafood markets and processing facilities are used or processed as fish meal and feed, but those generated from households and small seafood restaurants are currently treated as food waste. In addition, inadequately treated fishery by-products cause various problems such as spoiling urban landscape, creating odor and incubating pest. After identifying the generation and treatment of fishery by-products, the study suggests directions for the formulation of infrastructure for transition into resource circulation society, minimization of dumped waste and their eco-friendly recycling as resources, diversification of recycled goods and development into a high-value added industry. Finally, the study suggests detailed strategies for the directions such as establishment of legal and institutional foundation, separation of fishery by-products from wastes, development of technology tailored for commercialization, introduction of pilot projects for industrialization and cultivation of social enterprises.

Purpose: This study explores the relationship between future time perspective and older consumers' masstige product consumption, specifically, their intention to purchase masstige brand products, with a focus on their motivational drives from an functional value and symbolic value perspective. Research design, data and methodology: Data were collected through an online questionnaire from 419 people aged 54 to 64 years in South Korea and the hypotheses were examined using structural equation modeling. Results: Our results indicated that middle-aged and older consumers who have expanded future time perspective have higher intention to purchase masstige brands and their functional value and symbolic value of masstige brands were found to mediate future time perspective and intention to purchase masstige brands. Conclusions: The findings offer insights into masstige brand consumption by older South Korean consumers that may be useful for both academics and marketers.

전쟁에 있어서 해상봉쇄는 결정적인 전투행위를 담당하지는 않아도 적의 해상수송을 마비시키는 역할을 통해 경제전을 위한 가교 역할을 담당한다는 점에서 오랜시간 동안 전쟁의 수단으로 활용되어왔고, 한국전쟁에서도 유엔군은 클라크 라인을 통한 제한적 해상봉쇄로 전쟁에서 상당한 효과를 거두었다. 하지만 해상봉쇄의 중요성에도 불구하고 중국이 강력한 해군력을 바탕으로 해양강대국으로 부상한 현 상황을 고려할 때 한반도에서 다시금 전쟁이 발발한다면 어떻게 봉쇄선을 설정하여 해상활동을 차단할 것인지, 특히 중립국 선박이나 전시금제품을 수송하는 선박에 대해 어떻게 대응할 것인지에 대한 검토가 부족하다. 또한 봉쇄는 중립국과의 이해관계가 존재한다는 점에서 예민하고 융통성 있는 해군력 투사 수단으로 활용되어야 하므로 봉쇄의 합법성을 보장하기 위한 원칙을 고려하여 신중하고 합리적인 판단을 통해 활용될 때에만 그 목적을 달성할 수 있다는 점에서 그 실행에 앞서 신중한 검토가 필요하다. 따라서 본 연구에서는 해상봉쇄법 적용의 변천 과정을 재조명하고, 이를 통해 해상봉쇄의 합법성을 보장하는 기본원칙을 도출하고자 한다. 그리고 전시 한반도 근해에서 이러한 기본원칙의 적용방안과 함께 중립국 선박과 전시금제품 운반선박에 대해서는 어떤 대응이 필요한지를 검토함으로서 연구질문에 대한 답을 제시하고, 우리에게 주는 함의를 고찰하였다.

The United States is Korea's important trading partner, ranking third (13.7%) in exports of fishery products in Korea. The impact on exports to the United States is expected to be significant if the seafood import provisions under the MMPA are implemented in 2024 accordingly. It is expected that documents proving production information will be required for all items when exporting to the U.S. Therefore, this study attempted to examine the current status of exports and exporters in order to understand the actual conditions of major fishery products exported to the United States. Besides, there are currently no official system and procedures in Korea to prove production information for all fishery items, so we tried to suggest implications by examining distribution channels for major export items to the U.S. In this study, five items including seaweed and halibut as domestic aquaculture items, tuna and squid as deep-sea fishing items, and fish cake using imported raw materials were selected as the target items for distribution channel investigation. In addition, this study is meaningful in that it investigated the routes from production to processing, distribution, and export of each item and identified detailed distribution channel for major items exported to the U.S.
