  • This study investigated the flora of the Wang-ime oreum located on Seogwipo-si, Jeju-do, to basic data for the Jeju Island plant distribution. A total of 366 taxa were found with 94 families, 240 genera, 358 species, 1 subspecies, 6 varieties, and 1 forma. The floristic target species in Korea appeared as 2 taxa of grade V, 13 taxa of grade IV, 46 taxa of grade III, 5 taxa of grade II, and 49 taxa of grade I. There were 14 taxa for naturalized plants. The different plant life forms that appeared were large ground plants (M)(54 taxa), small land plants (N) (52 taxa), epiphyte (E) (6 taxa), indicator plants (Ch) (4 taxa), and semi-aquatic plants (H) (168 taxa), There were 34 and 48 taxa of plants(G) and annuals (Th) respectively. From these results, Wang-ime oreum, which is adjacent to ranches and grasslands, has little artificial interference, as more plants are distributed, and fewer naturalized plants are found than in Suwolbong and Dangsanbong. Accordingly, each oreum plays an important role in the flora of Jeju-do, thus a management plan tailored to the characteristics of the volcano is necessary.

  • A guest room section is the most important part of the hotel design. It contributes not only to the marketing but also to the effective distribution of the floor plan. This study is to provide the trends of the plan type of the guest rooms at the luxury resort hotels in Jeju-do through analyzing the typical floor plan type and surveying the area distribution of the guest room section. The purpose of the study is to provide the basic materials for the improvement of the quality of hotel guest rooms in Jeju-do, which is emerging as the international tourism destination of 21C. Here, we make the 13 luxury resort hotels in Jeju-do an subject of the study. They are divided into three grades by the size, quality, and the service.

  • Knowledge of the prevalence of human Toxoplasma gondii infection is required in the Republic of Korea. In this study, we surveyed the seroprevalence of T. gondii infection and analyzed the risk factors associated with seropositivity among residents in 2 administrative districts; Seoul and the island of Jeju-do, which have contrasting epidemiologic characteristics. Sera and blood collected from 2,150 residents (1,114 in Seoul and 1,036 in Jeju-do) were checked for IgG antibody titers using ELISA and for the T. gondii B1 gene using PCR. In addition, participants completed a questionnaire that solicited information on gender, age, occupation, eating habits, history of contact with animals, and travel abroad. The T. gondii B1 gene was not detected in all residents examined. However, ELISA showed 8.0% (89 of 1,114 sera) positive for IgG antibodies against T. gondii in Seoul and 11.3% (117 of 1,036 sera) in Jeju-do. In both districts, the positive rates were higher in males than in females, and those 40-79 years of age showed higher rates than other ages. In Seoul, residents older than 70 years of age showed the highest positive rate, 14.9%, whereas in Jeju-do the highest prevalence, 15.6%, was in those in their sixties. The higher seropositive rate in Jeju-do than in Seoul may be related to eating habits and occupations. The present results and a review of related literature are indicative of an increased seroprevalence of T. gondii in Korea in recent years.

  • An infiltration storage can be installed as a method of reducing runoff from catchment and increasing stream flow during the dry period by recharging groundwater. However, there is no proper model and method that can be used to design storage capacity of an infiltration storage in Korea. The purpose of the study is to evaluate capacities of infiltration storages planned on Jeju-do in Korea by modifying Storm Water Management Model (SWMM). The basic equations for the infiltration storage are same as those of the infiltration trench used in MIDUSS. Infiltration rates of the infiltration storages were first measured by double ring infiltrometers, and then the modified model was applied to evaluate adequacy for the capacities of three infiltration storages planned on Jeju-do in Korea. The application results show that the two infiltration storages with higher infiltration rates have adequate capacities to infiltrate the total water inflow to the storages. However, the other infiltration storage with lower infiltration rates has not sufficient capacity to infiltrate the total water inflow to the storage and release occurs to the downstream region. The simulation model and method applied can be used for capacity evaluation of future infiltration storages on highly pervious areas in Jeju-do.

  • 동절기에 제주도 지역에서 도래하는 떼까마귀의 유전적 특성과 집단 간 유연관계를 구명하기 위해, 미토콘드리아 COI 유전자 서열의 다형성에 기반한 모계 계통 구조와 계통 유연관계를 분석하였다. 떼까마귀 DNA는 우도와 제주도 내에서 발견된 깃털과 사체 시료에서 분리하였다. 결정된 COI 서열들(n=41)은 떼까마귀(Corvus frugilegus)에서 기존에 보고된 서열들과 97.0% 이상 일치하였다. 제주도 떼까마귀 COI 서열들은 3가지 haplotype(J01-J03)으로 구분되었으나 지역-특이적인 양상을 보이지 않아, 이들이 하나의 모계 기원에서 유래한 집단임을 알 수 있었다. 떼까마귀 전체 COI 서열에서 8개의 COI haplotype들이 발견되었다. 이 중 3가지 haplotype들은 러시아 동부, 몽골, 한국 등 동북아시아의 COI 서열들을 포함하였고, 나머지 5가지는 중앙아시아, 중동아시아, 러시아 서부, 유럽국가의 떼까마귀에서 발견되었다. 계통수 상에서 떼까마귀의 COI 서열들은 측소적 종분화 단계인 2아종, C. f. frugilegus와 C. f. pastinator인 2개의 모계 계통으로 뚜렷하게 구분되었다. DNA barcoding 분석을 통한 연구결과는 모계 계통의 구조, 계통 유연관계 및 분자생태를 이해하는 데 중요한 정보를 제공할 것이다.

  • 강원도 양구군 도솔산과 제주도에서 2종류의 미기록 귀화식물을 발견하였다. Hieracium caespitosum Dumort.는 양구군 도솔산에서 분포가 확인되었으며 조밥나물과 비교하여 두화의 수가 많고, 개화시기에도 근생엽이 달려 있는 특징이 있으며, 유럽이 원산지여서 유럽조밥나물로 신칭하였다. Trifolium incarnatum L.은 제주도 정실, 우도, 대정 가시오름 및 전라남도 보성 녹차단지 주변 등 여러 곳에서 발견되었으며 토끼풀속의 다른 식물들과는 꽃이 진홍색이고, 화서가 길게 발달하며 식물체가 직립하는 등의 특징으로 구별된다.

  • 한국산 설치류 중 등줄쥐(Apodemus agrarius)의 분류학적 연구를 위해서 제주도산 등줄쥐(Apodemus agrarius chejuensis)를 채집하였으며 형태적 및 염색체 분석을 한반도 내의 등줄쥐(A. agrarius coreae)와 비교 실시하였다. A. agrarius coreae와 A. agrarius chejuensis는 염색체 핵형에서는 같았으나, 형태적 형질에 있어서는 전자는 작은 형이었으며 후자는 큰 형이었다.
