A total of 19 species of three genera Dinophysis, Histioneis, and Parahistioneis of the family Dinophysaceae are reported here from samples obtained using a 20-µm mesh net from June 2006 to December 2014 around Jeju Island including the East China Sea, and 16 of these species are new to Korean waters. A checklist of the three genera of dinoflagellates reported from coastal and oceanic Korean waters is presented. Short descriptions and synonyms are given for each species. The dinoflagellates of the family Dinophysaceae belong to mostly marine species, and include many tropical and/or subtropical species. Recently, the composition of dinoflagellate species has changed around Jeju Island as well as in Korean waters due to global warming and climate change. Tropical and subtropical dinoflagellates occur frequently in the coastal waters of Jeju Island, which reflects the ecosystem shift around the sea adjacent to Jeju Island from a temperate to a subtropical / tropical region.

Porcine salmonellosis is an economically important disease affecting the global pig industry today. Salmonella (S.) Typhimurium is highly contagious and may rapidly spread within pig populations of herd. To investigate the prevalence of porcine salmonellosis in Jeju, a total of 12,885 blood sera of 96 pig farms from 2009 to 2012 were analyzed by microplate agglutination test. Antibodies to S. Typhimurium were detected in all of pig farms tested in Jeju Province, and the mean of seropositive rate of individual pig was 18.8%. The mean seropositive rate of S. Typhimurium in sows (46.7%) was 7 times higher than that of weaned or growing pigs (6.7%). The lowest seropositive rate (3.0%) was detected in 40 day-old pigs, and this result might be closely associated with the marked decrease of maternal passive immunity. The seropositive rate in winter (42.7%) was higher than in other seasons.

제주는 섬이라는 지리적 특성으로 인해 타 지역에 비해서 독특한 방언이 발달하였다. 더구나 15세기 이전의 고어들이 일부분 남아있어서 국어학 연구에도 매우 중요한 역할을 하고 있다. 그러나 제주의 문화인 방언을 관광에 이용하는 연구는 이루어지지 않고 있다. 즉 관광객들이 방언에 대해 정보를 얻으려 해도 이를 제공해줄 콘텐츠가 개발되어 있지 않아, 제주를 찾는 관광객들에게 제주 방언을 홍보하고 제주방언의 사용을 활성화 시킬 수 있는 방안이 필요하다. 따라서 본 연구에서는 관광 시 자주 사용되는 제주방언을 상황별로 나눠서 텍스트와 음성 정보로 관광객에게 제공하여 방언의 학습 및 실제 여행 시 사용할 수 있도록 돕는 콘텐츠를 제작한다.

The CSC-based HVDC system links the Jeju system to the mainland system. Because CSC-based HVDC is installed in Jeju, the reactive power is needed to transfer active power through the HVDC. In order to supply reactive power, switched capacitors and synchronous condensers are installed in Jeju system. The deterioration of established synchronous condensers, however, causes a reactive power supply capability decline and high maintenance cost. It brings about the instability of Jeju system and the incremental of maintenance and repair costs. In the future the installation of wind generators and additional HVDC system would aggravate the stability of Jeju system. Therefore, it needs to consider a countermeasure against above problems. In this paper, Analysis of several contingencies of Jeju system was peformed, and some contingencies caused voltage-reactive power problem was known. CPF method was introduced in order to make countermeasures to replace the synchronous condensers and to solve the voltage-reactive power problem. The location and capacity of reactive power sources were also decided. It could guarantee medium and long term stability of Jeju system.

Modern society is filled with the pursuit of material wealth and great convenience due to high technology that has been introduced to all facets of society. There is no exception to this in the field of construction. Modern construction, however, has caused environmental destruction and pollution, disturbing the coexistence of humans and nature. Therefore, this thesis aims to explore how humans and nature can maintain a mutually beneficial relationship by looking into the construction of Jeju's traditional dwelling house. This thesis examines the geographical features of Jeju and looks into how Jeju people have adapted themselves to nature. It is assumed that geographical features have created Jeju's unique environment and style of architecture and differentiated Jeju's traditional houses from those of other regions. Also, it is considered that geographical features had a large impact on traditional construction such as the floor plan and the layout of buildings. Accordingly, this thesis explores the way traditional houses protected house dwellers from the natural environment and examines the wisdom of our ancestors who took advantage of the natural environment. In addition, this thesis aims to contribute to creating Jeju's unique construction culture and environment by studying materials, structures, and forms that were applied to the traditional houses of Jeju.

Jeju, the biggest island in Korea, was registered as a World Natural Heritage in 2007. Recently, it was also voted as one of the New Seven Wonders of Nature. The need for academic awareness and tourist values on Jeju Island are understood. Gal-ot, one of the ten symbols for Jeju, is known for working clothes in general, despite its potential for cultural products because of its regional uniqueness and useful functional advantages. The authors conducted a comprehensive literature review and researched market trends of Gal-ot stores in Jeju to present development directions for cultural goods and to contribute to local economic improvement. Most stores were located in a semi-residential area and Jeju-si in Jeju Special Self-Governing Province. Most products were not available for sale due to difficulties in the production process and online utilization. High prices and similar color, fabric and style hurt competitiveness. Various experiencing programs of Gal-ot and persimmon dyeing were necessary to expand the main target from residents to tourists. Also, marketing strategies using the internet and design plans reflecting current trends were needed. This study would contribute to prepare developmental projects of cultural product and result in economical advantages on Jeju Island.

본 연구에서는 VESTAP을 활용하여 기후변화에 따른 제주도의 홍수 취약성을 평가하였다. 평가결과, 제주도 홍수 취약성은 현재(2010년대)보다 미래(2020년대, 2030년대, 2040년대)로 갈수록 지속적으로 증가하는 추세를 보였으며, 특히 2030년대를 기준으로 이전에는 제주시의 취약성이 서귀포시보다 높게 나타난 반면, 이후에는 서귀포시의 취약성이 제주시보다 높게 나타나 제주도 전반에 대한 취약성의 증대와 함께 지형 상 남북 간인 서귀포시와 제주시 간의 취약성 변화 특성을 확인할 수 있었다.

The objective of this study was to propose the priorities among the possible development strategies that can activate the industry while the market potential of cruise tourism industry has been increasing. To achieve the research aim, the A'WOT (SWOT-AHP) method was adopted in this study focusing on Jeju cruise industry. As a result of analysis, the strength factor (0.421) was the most important thing among the proposed factors. And, opportunity (0.348), weakness (0.135), and threat (0.096) factors were calculated in turn. Based on the A'WOT analysis, the most urgent thing among the strategy alternatives was 'Installation of dedicated department for Jeju cruise industry'. Accordingly, this result can be utilized as the fundamental data in order to make an optimal decision following by the environmental changes in Jeju cruise industry.

This study has the purpose to examine the elements of deducing site plan of contemporary architecture in Jeju by looking into the mainly used measures and value in establishing the site plan of contemporary architecture of Jeju. Being the initial decision making stage that serves as basis in creating design alternative and completes overall designing alternative frame, Site plan is the core stage of initial architectural planning. In addition, analysis of site plan concept the central overall idea for site plan offers the perspective to access the problem for solution in site plan. Therefore, through the analysis of elements to deduce the site plan concept of the contemporary architecture in Jeju, the characteristics of site plan concept that considered the placement and locality of Jeju can be objectively examined in planning out the site plan of contemporary architecture in Jeju, and such analysis results may become objective basic data in planning out the site plan of the contemporary architecture in Jeju.
