The current scallop fishery sector allows many scallops to remain in specified fishing zones, and this process leads to heavy losses in the sector. Scallop fishermen aim to harvest the remaining scallops to reduce their losses. To achieve this, a fisherman must understand the scallop ecology on the seafloor. In our previous study, we proposed a method for measuring scallops using wheeled robots. However, a wheeled robot must be able to resist disturbance from the sea to achieve high measurement accuracy. Strong anchoring of wheels against the seafloor is necessary to resist disturbance. To better understand anchoring performance, we confirmed the wheel anchoring capacity in water-containing sand in an experiment. In this experiment, we towed fixed wheels on water-containing sand and measured the resistance force acting between the wheel and the sand. Afterward, we considered the resistance force as the wheel anchoring capacity on the water-containing sand. The experimental results capture the tendency for the anchoring capacity of sand with/without water to increase with sinkage. The results also demonstrate that the anchoring capacity of water-containing sand is lower than that of non-water-containing sand. However, the results indicate that when the wheels possess lugs, their presence tends to increase the wheels’ anchoring capacity in water. Full article

The innovative thinking of artists highlights the influence of Bergson’s philosophy on modern art, and the perception of the relationship of the inner essence of “mind and matter” through observing and experiencing daily life helps artists design works according to the artists’ conception. The innovative thinking of learners is based on the creation of art, namely duration, movement, timeliness, and dynamics. We integrated the emotions of creators as the links of the creation of works with the “aesthetic duration” of the viewer, the “movement” rhythm of visual transformation of different “timeliness” provided by the workspace to evoke the “dynamics” of the viewers’ internal thoughts. In this article, the creative thinking of three works, namely Growth, Fisherman, and Virtuality and Reality, was analyzed for learners to discuss how the creators designed their works to connect and reflect their creative thinking and creation with the help of emotion. The results of this analysis of creative thinking helped students understand the process of artistic creation and have the creative characteristics of Bergerson’s philosophy. The emotional elements of the creator need to be integrated to evoke the deepest feelings and help viewers feel the beauty of works to the maximum. Full article

Fishing wealth is one of the richest resources in the Sultanate of Oman. It is considered as one of the most important economic developments that nation depends on in a larger way. The Sultanate of Oman is characterized by the presence of a large fishing fleet as the number of fishing vessels and boats in it. Good research with the application of modern technology in fishermen boats is required to increase the quality of fishing by providing fishermen with a safe and secure fishing experience. Artificial intelligence (AI) in boat automation technology is new and it is a mandatory demand for Oman’s fisheries sector. At the time of fishing, there are a lot of problems fishermen face such as weather changes, border tracking, navigation, illegal fishing, pirate attack, oil spill, technical fault in boats, etc. Therefore, the application of AI and related techniques in boat automation, information sharing, and preparation of documentation resources is very important in this sector. The main requirement for a fisherman is a high-quality fishing boat with proper communication devices to provide all the required information to fishermen and the control room. In this paper, a review has been made on fishermen’s boats with artificial intelligence for a sustainable fishing experience ensuring safety, security, navigation, and sharing information for Omani fishermen.

This study aims to understand MDR/RR-TB patients’ experience from seeking TB-related health care to diagnosis and treatment completion, as well as the social determinants with the waiting time for DST and treatment, pre-treatment attrition, and treatment outcome based on a retrospective cohort study. Univariate and multi-variate logistic regressions were used to analyze the associated factors. The median time of waiting time for DST and treatment was 24.00 and 30.00 days, respectively. Non-residential patients (aOR: 2.89, 95% CI: 1.14–7.70), registered before 2018 (aOR: 19.93, 95% CI: 8.99–48.51), first visited a county-level hospital (aOR: 4.65, 95% CI: 1.08–21.67), sputum smear-negative (aOR: 3.54, 95% CI: 1.28–10.16), and comorbid with pneumoconiosis (aOR: 7.10, 95% CI: 1.23–47.98) had a longer DST delay. The pre-treatment attrition was 26.9% (82/305). Elderly, non-residential patients and patients registered before 2018 were more likely to refuse MDR/RR treatment. However, in housekeeping/unemployment and farmer/fisherman, recurrent patients tended to take therapeutic measures actively. The successful treatment rate was 62.1% (105/169). Elderly, comorbidity with diabetes and sputum smear conversion time >1 month may lead to poorer outcomes. Immediate interventions should be taken to smooth diagnosis and treatment pathways and improve the social protections further so as to encourage patients to cooperate with the treatment actively.

The effects of climate change are much more pronounced in the Arctic region than in other places around the world. This paper highlights the practices of adaptation to climate change by Indigenous reindeer herders, e.g., Saami and Komi-Izhemtsy, and Pomor fishermen, in the Russian Arctic. Our major research question is: How does the interplay of social and environmental factors determine traditional reindeer herding and fishing in the Russian North in the context of climate change, including seasonal changes? A qualitative methodology was used in both reindeer herding and fishing communities using the same interview guide. As an analytical lens, we chose resilience theory combined with the actor–network theory. Resilience theory allows us to situate the adaptive capacity of reindeer herders and fisherman within a constantly changing context. The actor–network theory offers a non-human-centered framework which allows the reconstruction of the networks that emerge in the context of adaptation and link humans, material objects, and the living environment. We found that the traditional economic activity of reindeer herders and fishermen is significantly affected by socio-economic and environmental factors. Both reindeer herders and fishermen manage to adapt to the changing environment using local knowledge and different kinds of technical tools. However, socio-economic conditions and accelerating climate change put the resilience of Indigenous communities at risk. Full article

In the era of climate change and rapid urbanisation, communities and infrastructures need to be planned and designed in a way that promotes sustainable living. The provision of clean and affordable energy is a key to this aim. This paper proposes a technology assessment approach that is based on the triple bottom line (environmental, social and economic) sustainability framework. This approach can be employed in the technology screening that is involved in the early stages of the energy master planning process and can be applied to different community typologies in various locations and climates. The developed approach is demonstrated through a new urban renewal project case study in Fishermans Bend, Melbourne, in which a set of technological options were screened according to the project’s goals. The connection between the energy master plan and local and global sustainable development goals is discussed and policy interventions are proposed. The results show that the proposed approach could effectively enable the evaluation of the technological sustainability performance of the community by demonstrating the design trade-offs and the implementation of the sustainability objectives during the energy master planning process. Moreover, the proposed approach could provide guidance for effective policy making. It was found that government energy policies, regulations and incentives play a vital role in the feasibility of an energy master plan. Lastly, the proposed approach could facilitate the achievement of local and international targets, such as the UN SDGs, by 2050. Full article

The sustainability of coastal communities is emerging as a primary topic in policy groups. In Korea, the multifunctionality of small-scale fisheries is being emphasized, and the government has attempted various policies, such as the promotion of in-migration and the fishery industry. However, despite the diverse alternatives, the population and fisheries have been continuously downsizing. This trend threatens the sustainability and pluralistic values of coastal communities. This study identifies the crucial determinants needed to expand small-scale fisheries and enhance the economic motivation for sustainable coastal communities. The analysis is conducted with a two-stage Heckman selection model using the Korea Fishery Census and the Agricultural Census. The estimation results show that the socioeconomic incentives and performance of fisheries in coastal areas are limited. In particular, although the policy pays attention to young, highly educated, and in-migrant groups, it seems to have a limited preference for small-scale fisheries due to economic, societal, and institutional constraints. On the other hand, the family-oriented fishing activities and self-governance unique to fishing villages in Korea could improve the multifunctionality of small-scale fisheries in Korea. In addition, when a fishery household engages in production and sales activities as a member of a fraternity or collective wholesale contract, economic outcomes significantly increase. The results suggest that it is necessary to sustain communal socioeconomic activities by opening up communities and adjusting specific operating systems of self-governance. Full article

Issues of oil spills in various locations worldwide have been widely published in several studies. However, studies on policy management and strategies for handling cases related to oil spills are still limited. As one of the largest oil-producing countries with international shipping traffic, Indonesia is vulnerable to oil spills. Therefore, by drawing upon evidence from Bintan Island, this study aims to provide recommendations for stakeholders concerning governance and policy to address the oil spill case, which has had adverse social, economic, and environmental impacts. Data were collected from semi-structured interviews, focus group discussion, observation, actual online news, and official government reports using a case study approach. The result indicates that the local government is slow in responding to Bintan Island’s reoccurring yearly oil spillage. Policy responses are still focused on repressive and conventional methods. Hence, preventive and multi-stakeholder governance is required to handle oil spills. Furthermore, this study provides an overview of the oil spill problem and its management strategy in developing countries, especially Indonesia. Full article

Revealing the practice of the capital assistance system in coastal communities that are indicated to have deviated from the principles of social capital, and building an integrated model as a solution for improving fishermen’s low performance are the main objectives of this study. For this purpose, fishermen communities were chosen as the research sample. The research locations were focused on two provinces in Indonesia (Bengkulu and East Java provinces). Data were collected through observation, interview, and documentation methods. Discriminant and SEM/SmartPLS analysis methods were used to analyze quantitative data, while the descriptive analysis method was used to analyze qualitative data. The results show that the implementation of the capital assistance system by well-off fishermen (as capital providers) was proven to deviate from the principles of social capital because it was detrimental to small-scale/traditional fishermen. Six factors cause deviations in the capital assistance system: (a) the lack of “altruism cooperation” between well-off fisherman and small-scale/traditional fishermen; (b) mutual trust is not developed; (c) the powerlessness of the fishing community, which desperately needs funds for working capital; (d) government control is not effective; (e) the role of cooperative institutions (fisheries) as providers of funds/loan capital is still weak; and (f) an empowerment integrated model is considered capable of providing a comprehensive solution.

Approximately 381 million tons of plastic are produced globally every year, and the majority of it ends up as pollutants. In the environment, plastic waste is fragmented into microplastic particles less than 5 mm in size; owing to their small size, durability, and abundance, they can easily be dispersed, incorporated into the food chains, and enter the human body. The extent of microplastic exposure in the human body has become a major concern in many countries, including in Indonesia, the second largest plastic waste contributor in the world. Here, we report the detection of microplastics in human stools collected from a fisherman community in the coastal area of Surabaya, Indonesia. Microplastics were found in more than 50% of samples analyzed with a concentration ranging from 3.33 to 13.99 µg of microplastic per gram of feces (µg/g). HDPE was observed as the most prevalent type of microplastic, with an average concentration of 9.195 µg/g in positive samples. Different types of microplastics were also detected in seafood, staple foods, drinking water, table salts, and toothpaste, which were regularly used and consumed by the study participants. Results from this preliminary study indicate widespread contamination of microplastic in the human body and in consumables associated with the coastal populations of Indonesia. Full article

Background: Fishing is a risky occupation as injuries and fatalities in fishing vessels are quite common. This paper investigates the pattern of injuries aboard fishing vessels in Denmark to get a better understanding of areas where further action is needed to reduce the number of injuries and fatalities in Danish fishing vessels. Materials and methods: Data for this study, extracted from the Danish Fishermen’s Occupational Health Service’s database (in the period 1998–2012) and the Danish Maritime Authority’s accident report from 2013 to 2016, include 1840 injuries in Danish fisheries. Result: The results showed decreased injuries in the study period from 45 injuries and deaths per 1000 fishermen reported to the authorities to 12 injuries and deaths per 1000 fishermen in 2016: 2.1% (n = 39) of all reported injuries in the study period resulted in the death of a fisherman and the remaining injuries resulted in sick leave of more than one day; 52.5% (n = 600) of reported injuries involved fishermen who have less than one year’s experience of employment; 29% (n = 407) of injuries took place between 12:00 and 16:00, and the second largest number of injuries, 23.3% (n = 324), took place between 8:00 and 12:00. The incident rate of slip/fall injuries has decreased from 10.06 per 1000 fishermen in 1998 to 3.84 in 2016. The incidence rate of injuries caused by crushing also decreased, from 9.32 accidents per 1000 fishermen in 1998 to 2.56 in 2016. Most of the injuries, 74.5% (n = 1307), happened on the deck of the vessel. Sprain/strain was among the most common injuries (34.2%; n = 538) followed by fracture (24.8%; n = 391). Conclusion: This study indicated that the number of injuries had been gradually decreasing in Danish commercial fishing vessels in the period from 1998 to 2016. The rate of injuries had been declining due to several initiatives such as the establishment of The Danish Fishermen’s Occupational Health Services, training, safety campaigns, technological improvement and structural changes in fisheries management. However, there are still places for improvement. Full article
