This study investigated development method of governance of local residence, central and local government based on fishing ports as a new paradigm for restoration of sustainable space environment on Hyeonpo Harbor in Ulleung Island. According to the result of conducting a questionnaire survey on residents of Ulleung Island in order to carry out the research purposes, vulnerable living environment as poor accessibility and lack of hospital, community health center, and shopping district were pointed out as the biggest problem of residential environment in Ulleung Island of today. Secondly, there was a high recognition that development project on Ulleung Island of the government and local government is not actually contributing to the revitalization of regional economy and improvement in quality of life of Ulleung Island residents, and thirdly, lack of understanding on the importance or usage of various resources in Ulleung Island and insufficient support of the central government and local autonomous entity were pointed out as the bottleneck factors in implementation of the Ulleung Island development project. Fourthly, they perceived the current management level of Hyeonpo Harbor to be unsatisfactory. The results of this study demonstrated the importance of durability of development entities, vision of development of Hyeonpo Harbor, effort for the change of ownership mind, phased implementation considering reality of the area, and development that can provide small-scale profitable contents than a large theme.

The Japanese Flying Squid (Todarodes pacificus) is a commercially important species in South Korea and the most popular species among consumers. However commercial catches of Japanese Flying Squid have been declining since 2000. In this study, we conducted a stock assessment to identify stock status. This study differed from previous studies in two aspects: a greater amount of available fishing effort data was used, and data from China, Japan, and Korea were included. A CMSY (catch-maximum sustainable yield) model was used to estimate MSY, biomass and exploitation with Bayesian state-space implementation of the Schaefer (BSS) model for the method of stock assessment, and evaluated the species by dividing into two groups, 'Korea' and ' Korea·China·Japan'. In all cases, Japanese flying squid biomass showed a general decreasing trend. Additionally, the biomass estimated for 2020 was lower than the biomass necessary to achieve the maximum sustainable yield. To manage Japanese Flying Squid effectively, it is necessary to strengthen the resource management strategies of individual countries and prepare a cooperative plan among countries.

Particulate matter levels are rapidly increasing daily, and this can affect human health. Therefore, air pollutant emissions from sea vessels require management. This study evaluates the status of air pollutants, focusing on air pollutant emissions from the vessels of the Korea Coast Guard (KCG), and proposes national management measures to reduce emissions. According to a report recently released (2018) by the National Institute of Environmental Research (NIER), emissions from vessels constituted 6.4 % of the total domestic emissions, including 13.1 % NO_x, 10.9 % SO_x, and 9.6 % particulate matter (PM10/PM2.5). Among the rates of pollutant emission from vessels, the emission rates of domestic and overseas cargo vessels were the highest (50.6 %); the ratio of fishing boats was 42.6 %. With respect to jurisdictional sea area, 44.1 % of the emissions are from the south sea, including the Busan and Ulsan ports, and 24.8 % of the emissions are from the west sea, including the Gwangyang and Yeosu ports. The KCG inspects boarding lines to manage emission conditions and regulate air pollutant emissions, but it takes time and effort to operate various discharge devices and measure fuel oil standards. In addition, owing to busy ship schedules, inspection documents are limited in terms of management. Therefore, to reduce the air pollutant emissions of such vessels, regulations will be strengthened to check for air pollutants, and a monitoring system based on actual field data using KCG patrol ships will be established, for each sea area, to manage the emissions of such vessels. Furthermore, there is a need for technological development and institutional support for the introduction of environmentally friendly vessels.

This study aimed at investigating the content and meaning of royal garden(宮苑) sightseeing event in Pyoam Gang, sehwang's "Hogayugeumwongi" As the research method, descriptive research method was used, which is to consider and interpret the content and meaning in the historical records. Research results are summarized as follows. 1. "Hogayugeumwongi", which recorded the event that the King personally guided and explained the palace to the vassals, is a very precious historical records in Korean landscape gardening cultural history. Such thing is unprecedented in Joseon Dynasty as well as China. 2. The person who recorded this event was famous for shi seo hwa samjeol in the time, and the point that he was Pyoam, who was appreciated as 'the head(總帥) of artistic and literary circles(藝苑)', adds more value to the future generations. 3. The characteristic of this sightseeing event was to praise the vassals' labor, who contributed to the completion of Kyujanggak, to establish King Jongjo's direct rule in the early period of seizure of power, and eojin(御眞) dosa(圖寫), etc., which expressed the King's dignity. Jongjo utilized Geumwon, a forbidden place in the palace, to give a special privilege to the vassals' effort, who took a great part in realizing his political ideal. 4. One of sightseeing lines toward the backyard of Changdeok Palace could be identified. Though the sightseeing lines toward the backyard were not fixed, however this might be the best sightseeing line which Jongjo intentionally chose to enjoy that day's flavor of autumn. 5. The characteristic of this event was informal and somewhat extemporary 'sightseeing'. Therefore, it is considered, that day's event was relatively private and free 'play(遊)', while 'sanghwaeojoyeon(賞花漁釣宴)', which Jongjo gave to the vassals middle after his reign, was a royal 'banquet', which prepared frames, such as event holding time and form, qualification for participation, e.g. flower viewing, fishing, writing poems, etc. This research has a significance that it considered the content and meaning in historical records including the front and the rear context that "Hogayugeumwongi" was written through the consideration of related historical materials. "Hogayugeumwongi" can be utilized as a material for storytelling with regard to royal garden sightseeing in future as a valuable cultural content, also, follow-up study on this is necessary.

In order to extract meaningful information from the excellent farming settlement cases of young farmers published by KNCAF, we studied the key words with text mining and created a word cloud for visualization. First, in the text mining results for the entire sample, the words 'CEO', 'corporate executive', 'think', 'self', 'start', 'mind', and 'effort' are the words with high frequency among the top 50 core words. Their ability to think, judge and push ahead with themselves is a result of showing that they have ability of to be managers or managers. And it is a expression of how they manages to achieve their dream without giving up their dream. The high frequency of words such as "father" and "parent" is due to the high ratio of parents' cooperation and succession. Also 'KNCAF', 'university', 'graduation' and 'study' are the results of their high educational awareness, and 'organic farming' and 'eco-friendly' are the result of the interest in eco-friendly agriculture. In addition, words related to the 6th industry such as 'sales' and 'experience' represent their efforts to revitalize farming and fishing villages. Meanwhile, 'internet', 'blog', 'online', 'SNS', 'ICT', 'composite' and 'smart' were not included in the top 50. However, the fact that these words were extracted without omission shows that young farmers are increasingly interested in the scientificization and high-tech of agriculture and fisheries Next, as a result of grouping the top 50 key words by crop, the words 'facilities' in livestock, vegetables and aquatic crops, the words 'equipment' and 'machine' in food crops were extracted as main words. 'Eco-friendly' and 'organic' appeared in vegetable crops and food crops, and 'organic' appeared in fruit crops. The 'worm' of eco-friendly farming method appeared in the food crops, and the 'certification', which means excellent agricultural and marine products, appeared only in the fishery crops. 'Production', which is related to '6th industry', appeared in all crops, 'processing' and 'distribution' appeared in the fruit crops, and 'experience' appeared in the vegetable crops, food crops and fruit crops. To visualize the extracted words by text mining, we created a word cloud with the entire samples and each crop sample. As a result, we were able to judge the meaning of excellent practices, which are unstructured text, by character size.
