This study was conducted to investigate the relationship between groundwater level change and a large earthquake using the data of groundwater and seawater intrusion monitoring wells in Jeju Island. Groundwater level data from 13 observation wells were analyzed with a large earthquake. The Earthquake occurred at Sumatra, Indonesia (Mw = 7.7) on 13 June 2010, and groundwater level anomalies which seems to be related to the Earthquake were found in 6 monitoring wells. They lasted for approximately 16~27 minutes and the range of groundwater level fluctuations were about 1.4~2.4 cm. Coefficient of determination values for relationship between groundwater level change and transmissivity, and response time were calculated to be $R^2$ = 0.76 and $R^2$ = 0.96, respectively. The study also indicates that the high transmissivity of aquifer showed the high goundwater level changes and longer response time.

Although women's economic participation has been increasing in Korea, the utilization of educated women's labor is still low. Therefore, vocational training programs for women are both important and necessary. This study examines the vocational training programs for women offered by the three largest vocational training centers in Jeju: the Woman Resources Development Center, the Jeju Women's Development Center, and the Seogwipo City Women's Cultural Center. This study also analyzes the students' satisfaction with these vocational training programs and identifies the related variables that cause differences in their levels of satisfaction. The sample includes 397 respondents who were surveyed from June 23 to September 12, 2008. Moreover, the data are analyzed by conducting a one-way ANOVA, t-test, and Duncan's Multiple Range(DMR)test. The major results of the study are as follows. First, the vocational training programs in Jeju consist of lectures that cover various subjects. The programs mainly focus on work that offers relatively low wages and requires few skills, and the duration of the programs is short. Second, the original goal of the programs does not meet the needs of women who are seeking employment. The participants respond that they want more appropriate programs that are designed by considering their need for employment, support them in finding a job, and re-educate them. Third, most of the participants are satisfied with their vocational training experiences, and their satisfaction with the instructors is especially high. The differences in their levels of satisfaction are caused by economic characteristics such as the location of the student's residence, home ownership, and the level of life. The results of this study suggest that there is a need to separate vocational/employment training from general education for women. Moreover, the vocational training programs for women should be more specialized according to the different needs of each group.

In the field of architecture, the sustainable architectural concept, "green buildings," has been suggested as an alternative to solve the environmental problems; however, the concept has not yet been converted to awareness and development of related technology. The leading role of public sector has been socially and economically influential in the nation, hence green public buildings are significant to stimulate the spread of green buildings in the nation. This study is to draw an appropriate method of implementing the green building concept to the two main government office buildings of Jeju Special Self-Governing Province based on the plan to improve the work environment; it is also to provide long-term directions of implementing policies and reference for the public and private sector to utilize the green building concept. Its research methodology was the survey method. A total of 142 questionnaires were returned by government employees of the two buildings. It accounts for 20% of the total number of 711 workers of the buildings. According to the analysis of the returned questionnaire, the majority of the surveyed have a positive evaluurned toward the introduction of green buildings due to their expecturned for the possible i the buildingstheir work environment. In addition, they showed more interest in space planning with natural ventilation than automatic systems regarding applied methods for green buildings.

Objective: The purpose of this study was to investigate the effect of functional ankle instability (FAI) and surgical treatment (ST) on postural stability and leg stiffness during vertical-drop landing. Method: A total of 21 men participated in this study (normal [NOR]: 7, FAI: 7, ST: 7). We estimated dimensionless leg stiffness as the ratio of the peak vertical ground reaction force and the change in stance-phase leg length. Leg length was calculated as the distance from the center of the pelvis to the center of pressure under the foot. Furthermore, the analyzed variables included the loading rate and the dynamic postural stability index (DPSI; medial-lateral [ML], anterior-posterior [AP], and vertical [V]) in the initial contact phase. Results: The dimensionless leg stiffness in the FAI group was higher than that of the NOR group and the ST group (p = .018). This result may be due to a smaller change in stance-phase leg length (p = .001). DPSI (ML, AP, and V) and loading rate did not show differences according to the types of ankle instability during drop landing (p > .05). Conclusion: This study suggested that the dimensionless leg stiffness was within the normal range in the ST group, whereas it was increased by the stiffness of the legs rather than the peak vertical force during vertical-drop landing in the FAI group. Identifying these potential differences may enable clinicians to assess ankle instability and design rehabilitation protocols specific for the impairment.

The purpose of this study is to propose a transit accessibility analysis method based on temporal variability of travel time. In this study, transit accessibility was defined in three levels (in transit route, spot and region unit) to present findings from different spatial scopes. Recently, Jeju special self-governing province reorganized bus system of the island. To compare transit accessibility before and after transit policy implementation, the reorganized bus system of Jeju special self-governing province was selected as a case study. This study used General Transit Feed Specification (GTFS) data format as storage public transit information, and calculated travel time using ArcGIS GTFS networks analysis tools. In the analysis of individual transit route level, we found the 3 types of accessibility changes which is increments, no significant changes and reductions and these results come from transit route change (number of transfer, distance change) rather than changes of vehicle interval. We found increases of inflow and outflow speed in most target spots and overall transit accessibility has been substantially improved in Jeju island. This study implies that accounting for temporal variability of travel time in accessibility analysis can result in more useful and sophisticated accessibility information in decision-making processes.

본 연구는 다양한 빅데이터를 지역관광 정책에 활용한 제주특별자치도의 사례를 토대로, 관광빅데이터의 활용성과와 과제를 제시하였다. 가장 큰 활용성과는 관광빅데이터를 통해 급변하는 관광트랜드와 관광업계의 동향을 시의성있고 구체적으로 파악할 수 있게 되었고, 기존 관광통계를 정교화하는데 활용할 수 있었다는 점이다. 여기서 더 나아가 제주는 빅데이터의 활용 범위를 관광 현상 이해의 수준을 넘어 실시간 맞춤형 서비스 플랫폼 구축까지 영역을 확장하였다. 이것이 가능했던 이유는 데이터 수집 및 분석 환경 구축과 산·관·학의 협력적 거버넌스가 조성되었기 때문이다. 향후 해결해야 할 과제는 첫째, 민간 데이터셋 위주의 분석으로 예산 의존적이라는 한계와 둘째, 스마트관광의 궁극적 목표인 개인맞춤형서비스 구축을 위한 개인수준 데이터 수집 인프라, 개인정보보호법 등의 제도적인 문제의 해결이다. 마지막으로, 데이터 분석과 데이터 연계에 도달하기까지의 전문성과 기술적 한계들이 남아 있다.

Background: The equine temporomandibular joint (TMJ) has a complex anatomical structure that makes diagnosis of TMJ disorders difficult. Computed tomography (CT) is now available in equine medicine; hence, TMJ evaluation has become more convenient. Objectives: The objectives of this study were to describe the CT features of the TMJ in Jeju horses and to compare these features with those of Thoroughbreds. Methods: In this report, the TMJs of 10 Jeju horses (mean age: 4.5 ± 1.9 yr; mean body weight: 282.6 ± 40.3 kg) and 6 Thoroughbreds (mean age: 7.3 ± 1.6 yr; mean body weight: 479.7 ± 44.0 kg) were examined using CT. After CT scanning, the Hounsfield units (HU) and height to width ratio (H:W) of the mandibular condyle were measured. Results: The mean H:W in Jeju horses was significantly lower than that in Thoroughbreds. The mean HU in Jeju horses was lower than that in Thoroughbreds; however, the difference was not significant. The most frequent CT finding was an irregular medial margin of the mandibular condyle in both breeds. Conclusions: In this study, the shape of the mandibular condyle in Jeju horses was flatter than that in Thoroughbreds. This report could be useful in evaluating the TMJ in Jeju horses. Moreover, CT could be a pragmatic choice for the examination of the TMJ in horses.

This study was conducted to lay the foundation for considering the qualitative aspects of environmental resources by calculating the weight of each environmental resource to calculate the total amount of environmental resources in Jeju. By comparing and analyzing the results of the expert survey conducted in 2011 and the results of the expert survey conducted in 2011 and 2022, changes in experts' perceptions and implications over time were derived. In addition, based on the results of the recent survey, the weight according to the relative importance was calculated to lay the foundation for calculating the total amount of environmental resources in Jeju. The results of this study are expected to provide basic data necessary for the successful institutionalization of the total environmental resource system by providing a scientific basis for the calculation of the total environmental resource. As a result of comparing the survey conducted in 2011 to the survey conducted in 2022 to establish a total environmental resource management plan in Jeju Special Self-Governing Province, there was a difference in the relative importance of the environmental resource category. Although the ranking between categories did not change, it was confirmed that the relative importance of the natural and local resource environment decreased and the relative importance of the living environment field increased significantly. Over time, the importance of plants and wildlife increased, the importance of landscapes and topographic geology decreased, the importance of wetlands and caves increased, and the importance of Gotjawal, natural monuments, and cultural history decreased. In the living environment category, the importance of water pollution increased significantly, and in the humanities and social environment category, the importance of population increased and the importance of industry decreased. It is judged that most changes in item importance are largely influenced by changes in the background of the times and overall perception. It was confirmed that the importance of plants, wildlife, wetlands, and caves with relatively high awareness and the importance of water pollution, which is emerging as a regional problem, have all increased significantly due to structural problems of population age.
