Objectives Haenyeo are Korean professional women breath-hold divers in Jeju island. The aim of this study was to investigate the clinical characteristics of depressed Haenyeo group, compared to non-Haenyeo depressed group. Methods This study included 75 Haenyeo and 340 non-Haenyeo with depressive disorders recruited from the Dementia Early Detection Program in Jeju island. Structural diagnostic interviews were performed using the Korean version of Mini International Neuropsychiatric Interview. All patients completed the questionnaires, including the Subjective Memory Complaints Questionnaire (SMCQ), the Patient Health Questionnaire-15 (PHQ-15), and the Blessed dementia scale. Depression was evaluated by the Korean version of short form the Geriatric Depression Scale (K-SGDS) and cognition was assessed by the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) assessment packet. Results Although the mean scores of the K-SGDS were similar between Haenyeo and non-Haenyeo depressed groups, the Haenyeo group showed a higher mean score on the PSQ-15 (p < 0.001, ANCOVA adjusting for age, the K-SGDS and education). The Haenyeo group showed poorer performance on the Korean Version of Frontal Assessment Batter (p < 0.001), the Mini-Mental State Examination in the Korean version of the CERAD Assessment Packet (p < 0.018), the word fluency test (p < 0.001), and the word list memory test (p = 0.012) in ANCOVA adjusting for age and education. The mean SMCQ score was higher in the Haenyeo depressed group than in the non-Haenyeo depressed group. Conclusions The Haenyeo depressed group shows cognitive dysfunction, especially frontal lobe dysfunction, compared to the non-Haenyeo depressed group, indicating the Haenyeo depressed group may have more severe frontolimbic dysfunction due to chronic exposure to hypoxia. The Haenyeo depressed group suffers more somatic symptoms than the non-Haenyeo depressed group.

Jeju Haenyeo is in danger of extinction, and the issue of labor force reproduction is emerging as an important agenda. The traditional method of labor force reproduction based on matrilineal succession is gradually disappearing, and part of its role is being taken over by vocational training institutions such as Jeju Haenyeo School. In order to maintain the social, economic, and cultural sustainability of Jeju Haenyeo, sustainable labor reproduction is an essential prerequisite, so multidimensional study on the labor reproduction issue of Jeju Haenyeo has important academic and policy implications. Accordingly, we analyzed previous studies directly and indirectly related to the reproduction of Jeju Haenyeo's labor force and the role of vocational training institutions in labor force reproduction. Based on this, we presented three issues that should be addressed. First, a detailed analysis of the role of Jeju Haenyeo School as a key platform for reproducing the Jeju Haenyeo's labor is required. Second, it is important to pay attention to the role of social capital in the reproduction of the Jeju Haenyeo labor. Third, a qualitative analysis process is needed to understand the meaning of the experiences in order to measure the organic relationships centered on the haenyeo community.

JejuHaenyeo(women diver) culture has been designated as UNESCO Intangible Cultural Heritage of Humanity(ICH) in 2016. However, the number of new Haenyeo is decreasing due to the hardships and difficulties of Haenyeo job, and the aging factor of Haenyeo is threatening the cultural preservation and inheritance. The study aims to analyze JejuHaenyeo's awareness on self, community and UNESCO ICH designation. The study further aims to check any significant difference in Haenyeo's self-awareness per age group to conclude an effective strategy for permanence of Haenyeo culture. 228 JejuHaenyeo were interviewed at "The 10th JejuHaenyeo World Festival" around the Jeju Haenyeo Museum in Gujwa-eup, Jeju-si. The test result shows the difference per age group on awareness on self and UNESCO ICH designation status. The younger the generation of Haenyeo it gets, the awareness on self and UNESCO ICH designation status of Haenyeo gets lowerer. Without an immediate improvement to supplement JejuHaenyeo's awareness on self and UNESCO ICH designation status, preservation and inheritance of JejuHaenyeo culture may not be an easy task in the future.

This study analyzes previous research on 'The Self-Governance of the Commons' to overcome 'The Tragedy of the Commons', and derives elements for successful commons management. These factors are compared and analyzed with the social and economic attributes of the Jeju Haenyeo community, a successful community self-governance model. In addition, in the recently changing environment, it is revealed whether this internal community mechanism can be useful in the future. The goal is to reveal what social and economic factors will help the sustainability of the Jeju haenyeo community in the future. As a result of analyzing the internal operating mechanism of the Jeju haenyeo community, the production and distribution system that improves trust and reciprocity, the inherent sense of community, the division of roles between formal and informal organizations, and the institutionalized explicit and implicit norms within the organization served as internal and external strengths of community sustainability. However, the closure of the network, the crisis of productivity, the weakening of homogeneity, and the emergence of new subjects acted as internal and external weaknesses. In conclusion, for the sustainability of the Jeju Haenyeo community, it is necessary to reorganize the reproductive function of labor using the haenyeo school, to maintain clarity on the subject of livelihood and cultural transmission, and guarantee the income of Haenyeo.

Background: Water pressure and muscle contraction may influence bone mineral density (BMD) in a positive way. However, divers experience weightlessness, which has a negative effect on BMD. The present study investigated BMD difference in normal controls and woman free-divers with vertebral fracture and with no fracture. Methods: Between January 2010 and December 2014, traditional woman divers (known as Haenyeo in Korean), and non-diving women were investigated. The study population was divided into osteoporotic vertebral fracture and non-fracture groups. The BMD of the lumbar spine and femoral neck was measured. The radiological parameters for global spinal sagittal balance were measured. Results: Thirty free-diving women and thirty-three non-diving women were enrolled in this study. The mean age of the divers was $72.1{\pm}4.7$ years and that of the controls was $72.7{\pm}4.0$ years (P = 0.61). There was no statistical difference in BMD between the divers and controls. In divers, cervical lordosis and pelvic tilt were significantly increased in the fracture subgroup compared to the non-fracture subgroup (P = 0.028 and P = 0.008, respectively). Sagittal vertical axis was statistically significantly correlated with cervical lordosis (Spearman's rho R = 0.41, P = 0.03), and pelvic tilt (Spearman's rho R = 0.46, P = 0.01) in divers. Conclusion: BMD did not differ significantly between divers and controls during their postmenopausal period. When osteoporotic spinal fractures develop, compensation mechanisms, such as increased cervical lordosis and pelvic tilt, was more evident in traditional woman divers. This may be due to the superior back muscle strength and spinal mobility of this group of women.

It has been 15 years since Jeju Island first was designated as one of UNESCO Biosphere Reserve areas. Jeju currently holds 5 UNESCO designations and the UNFAO Globally Important Agricultural Heritage (GIAHS). The 5 UNESCO global heritages that Jeju honors are the World Natural Heritage, Biosphere Reserve, Global Geoparks Network, Chilmeoridanggut Intangible Cultural Heritage (ICH) and JejuHaenyeo ICH. The UNFAO GIAHS that Jeju honors is Jeju Batdam Agricultural Heritage System. Those global titles are highly valued and recognized for environmental preservation and those global designations have attracted more visitors to the island. It is essential to see if Jeju global level heritages are recognized as they deserve attentions from home and abroad yet no holistic analysis on those 6 global level designations as a whole has been progressed to see the perception level among residents and visitors. The study aims to see the perception level of Jeju global Heritages, impact of global recognitions and the channels of the perception level. UNESCO World Natural Heritage and Haenyeo ICH have showed the highest perception level due to designation process and the amount of promotion by the managing division of Jeju municipality. The routine survey as per the result of the study regarding the perception level of those global designations could benefit Jeju tourism direction and help to preserve the island and culture.

This study applied the theory of Landscape Ecology to representative resources of Jeju Olle-gil, which is a representative subject of walking tourism, to identify ecological characteristics and to establish a technique for landscape ecological analysis of Olle-gil resources. Jeju Olle Trail type based on the biotope type, major land use, vegetation status around Olle Trail and roads were divided into 12 types. Based on the type of ecological tourism resource classification, the Jeju Olle-gil walking tourism resource classification was divided into seven types of natural resources and seven types of humanities resources, and each resource was characterized by Geotope, Biotope, and Anthropopope, just like the landscape ecology system. Geotope resources are strong in landscape characteristics such as coast and beach, rocks, bedrocks, waterfalls, geology and Jusangjeolli Cliff, Oreum and craters, water resources, and landscape viewpoints. The Biotope resources showed strong ecological characteristics due to large tree and protected tree, Gotjawal, forest road and vegetation communities, biological habitat, vegetation landscape view point. Antropotope include Culture of Jeju Haenyeo and traditional culture, potting and lighthouses, experience facilities, temples and churches, military and beacon facilities, other historical and cultural facilities, and cultural landscape views. Jeju Olle Trail The representative resources for each type of Jeju Olle Trail are coastal, Oreum, Gotjawal, field and Stonewall Fencing farming land, Jeju Village and Stone wall of Jeju. In order to learn about the components and various functions of the resources representing the Olle Trail's ecological culture, the landscape ecological technique was interpreted. Looking at the ecological and cultural characteristics of coastal, the coast includes black basalt rocks, coastal vegetation, coastal grasslands, coastal rock vegetation, winter migratory birds and Jeju haenyeo. Oreum is a unique volcanic topography, which includes circular and oval mountain bodies, oreum vegetation, crater wetlands, the origin and legend of the name of Oreum, the legend of the name of Oreum, the culture of grazing horses, the use of military purposes, the object of folk belief, and the view from the summit. Gotjawal features rocky bumps, unique microclimate formation, Gotjawal vegetation, geographical names, the culture of charcoal being baked in the past, and bizarre shapes of trees and vines. Field walls include the structure and shape of field walls, field cultivation crops, field wall habitats, Jeju agricultural culture, and field walls. The village includes a stone wall and roof structure built from basalt, a pavilion at the entrance of the village, a yard and garden inside the house, a view of the lives of local people, and an alleyway view. These resources have slowly changed with the long lives of humans, and are now unique to Jeju Island. By providing contents specialized for each type of Olle Trail, tourists who walk on Olle will be able to experience the Olle Trail in depth as they learn the story of the resources, and will be able to increase the sustainable use and satisfaction of Jeju Olle Trail users.
