Background: Hydrogen sulfide is a toxic substance that humans can be exposed to occupationally, and cases of hydrogen sulfide poisoning of workers in industrial sites are commonly reported. However, there have been no cases of poisoning of the public due to an unauthorized discharge of wastewater, so it is important to describe this incident. Case presentation: In a small village in Jeollanam-do, Republic of Korea, accounts of a terrible stench had been reported. A 26-year-old man who lived and worked in a foul-smelling area was taken to the emergency room with a headache, dizziness, nausea, and repeated syncope. A subsequent police and Ministry of Environment investigation determined that the cause of the stench was the unauthorized discharge of 9 tons of wastewater containing hydrogen sulfide through a stormwater pipe while the villagers were sleeping. The patient had no previous medical history or experience of symptoms. Leukocytes and cardiac markers were elevated, an electrocardiogram indicated biatrial enlargement, left ventricular hypertrophy, and corrected QT interval prolongation. Myocardial hypertrophy was detected on a chest computed tomography scan, and hypertrophic cardiomyopathy was confirmed on echocardiography. After hospitalization, cardiac marker concentrations declined, symptoms improved, and the patient was discharged after 7 days of hospitalization. There was no recurrence of symptoms after discharge. Conclusions: We suspect that previously unrecognized heart disease manifested or was aggravated in this patient due to exposure to hydrogen sulfide. Attention should be paid to the possibility of unauthorized discharge of hydrogen sulfide, etc., in occasional local incidents and damage to public health. In the event of such an accident, it is necessary to have government guidelines in place to investigate health impact and follow-up clinical management of exposed residents.
Climate change and large-scale human interference increase flow instability due to changes in watershed flow and sediment transport patterns. There are local problems in solving problems related to sediments, namely the existence of specific problems at specific sites or areas, and the resolution of these problems is limited to short-term and regional, resulting in other temporal and spatial influences and impacts. Therefore, this study intends to introduce and propose a conceptual framework for comprehensive sediment management in terms of watershed scale for solving problems related to sediments in watersheds. In the watershed scale, comprehensive sediment management should be done, to do this, a comprehensive understanding of the movements of sediments accompanied by cooperation with science-policy-operation-residents should be given priority.
This study was carried out to provide basic data. his research conducted the survey using face to face survey and board survey during about 2 months from Oct. to Nov. in 2009 for users of Bongje Mt., a small-sized mountain at downtown, and Acha Mt., a big-sized mountain at outskirt so as to compare the differences of using behavior by forms and size of urban forest in living area of Seoul. Characteristics of urban forest users, using behavior, demands and satisfaction of facilities and management and pass pattern were set as research items. The thing in common for using behavior is that both genders of main users were in more than 40s~60s. They showed the highest using rate from 7 a.m. to 12 p.m. and high rate for using nearly everyday or visiting two or three times per a week. In addition, it's judged that the accessibility from dwelling area to entrance of urban forest in living area is good and satisfaction for the standard of facilities and their management in forest way was relatively low. For the complement and essential facilities, 'sanitary facilities' showed the highest rate. For the differences of using behavior, most of Bongje Mt. users were residents living within a 2km radius (under the standard of walking) and they moved by average 1.3km. And, they preferred short-time activities of about 24 minutes. On the other hand, main users of Acha Mt. were residents living within a 4km radius (under the standard of walking) and people of other regions. and 60% of them preferred the passage route taking 3hours half over 6km. Through the survey on using behavior of urban forest in living area of Seoul, with different using form and forest size, introduction of using program for main users or managing method of differentiations for introduced facility's management should be properly applied. Especially, urban forest should be systematically managed like park green as expected that residents's using of urban forest will be increased with the increase of leisure time.

To investigate the exposure and health risk assessment for the residents near the D-asbestos mine in Chungbuk, Korea. We analyzed asbestos in the 20 ambient air and 23 activity based samples near the mine. The airborne sample results are showed that 8 of 20 samples ranged between 0.0025 to 0.0029 f/cc (fiber per cubic centimeter) and the others were below the detection limit by phase contrast microscopy (PCM). In addition, asbestos fibers were under the detection limit or not being by transmission electron microscopy (TEM). Based on interview and survey targeting the local residents, we made the activity based sampling (ABS) scenarios fit to the conditions of field. At the same time, we calculated the excess lifetime cancer risk (ELCR) of these ABS scenarios according to the ELCR average value and 95% upper confidence limit (UCL). At the case of weed whacking, soil digging and sweeping yard scenario, 95% UCL of ELCR exceeded the $1{\times}10^{-4}$, acceptable risk range for exposure. Based on our study results, it is necessary safety measures such as risk communication, abatement or management of naturally occurring asbestos (NOA).

Village-concentrated agricultural regional development projects that aim for increased profits are now being aimed at core agricultural and fishing areas. These agricultural and fishing stimulus projects aim to not only increase the net profit of local citizens but also improve their living conditions. As the industry itself has changed, local rural areas have also changed in various ways. One such aspect is the emergence of rural-urban complexes known as "rurban" areas. These naturally occurring rurban regions are created by a combination of complex urban infrastructure while maintaining the insulated rural communities that agricultural areas are usually so readily identified by. "Jeongeupsi Naejangsnagdong", the target of this research, also specifies the unaltered surrounding natural environment of rural areas while at the same time containing complex central living areas typically found in urban areas. This research suggests that the direction of residents' participation in community-level rurban projects could solve the problems found in existing top-down government development projects. This research also suggests rurban area activation plans to improve living conditions through analysis of both local rurban agricultural characteristics and citizen demands. In order to encourage citizen autonomy and self-governing attitudes, citizen-strengthening workshop programs are proposed, such as citizen workshops or pilot activities. This research was carried out by target area analysis, rudimentary planning, development direction setting, detailed project planning, and finally project processing. This procedure established three goals, which are walking environment improvement, community infrastructure establishment, and good living environment establishments, based on actual site research and citizen demands. This research suggests plans to activate community groups that were already established and reflect citizen needs as the main avenues for local businesses. This research is predicted to promote more active and successful growth through autonomy in stimulating these increasingly emerging rurban agricultural regions.

The goal of international development projects is to assist sustainable development in recipient countries through foreign aid from donor countries. However, despite the need for both countries to negotiate and work together from the initial stages to maintain sustainability after the project, clear guidelines or standards have not been established. Additionally, despite the need for donor countries, which are relatively advanced, to understand the situation of recipient countries, many projects are donor-centric and fail to prioritize the value of sustainability. Therefore, this study extracted economic, social, and environmental risks that threaten sustainability through literature review and proposed a sustainability framework based on these criteria. To validate framework, actual international development cases conducted by advanced donor countries such as Australia, the United States, and Japan, in collaboration with South Korea, were analyzed by applying content analysis with the reports, which covers the overall contents from the planning stage to the operation stage. Analysis of sustainability perspectives focused on economy, society and the environment, advanced donor countries emphasized (1) the importance of pre-assessment, (2) the need for coordination with the local population and communities despite the existence of donor-specific values, and (3) addressing economic considerations such as pre-operational and maintenance costs, social communication with the local population, and environmental considerations starting from the initial stages of construction regarding the treatment of pollutants as values to be improved. Compared to other advanced donor countries, the Republic of Korea should also focus on consultation with local residents to achieve social integration, and improve sustainability by deployment the managers in local sites for better negotiation.The proposed framework in this study will serve as a tool to enhance communication among the countries and the locals, with the expectation of increasing project efficiency and sustainability.
The aims of this study concerning tourists travelling in the island of Jeju include: to identify and assess the promotional efforts for traditional Jeju cuisine; and to identify the impacts of those efforts on customers and tourists. The analyses revealed that continuous promotion efforts, along with changes in the cooking methods and the development of new menus, are needed for the items of traditional Jeju cuisine that are relatively unknown to tourists and that fail to satisfy customers. Customers seeking Jeju food reported high satisfaction with such items as grilled meat and fish, steamed meat and fish, and raw fish(hoe), so those cooking methods must also be continually improved. Promotional efforts had impacts on the satisfaction and revisit rates of customers while the recognizability of foods offered had impacts on all areas, including the satisfaction and revisit rates of customers as well as word-of-mouth advertising among them. There needs to be an experience-oriented or educational program that introduces customers to traditional Jeju cuisine. Since customers and tourists gain information on traditional Jeju cuisine from the recommendations and word-of-mouth advertising from the locals they meet on the island, traditional Jeju cuisine should also be advertised to the local residents. The commercial merchandising of Jeju culinary culture and making festivals based on it must, therefore, be preceded by studies on how to increase the locals' awareness of local traditional cuisine.

This study proposes the difference of awareness and improvement plan of building-related landscape systems through a cognition survey of building owners, public officials, and experts. The main results are as follows. First, all three groups are highly aware of the need to secure urban green spaces. Even if private property rights are restricted, the level of awareness that green space should be secured for public benefit is high. The level of interest in the building-related landscape system was also surveyed to a greater degree. Second, the survey respondents, including the building owner group, answered that there is a need to strengthen the building-related landscape area standards. It can be seen that there is a need to revise the relaxation of the building-related landscape area standards through an amendment of the Building Ordinance in many local governments. Third, most municipalities are not equipped with an organizational system that can promote the work of building-related landscape. It is necessary to newly hire civil servants for landscape design, maintenance, and management specialization, or to expand co-working relationships with related departments. Fourth, building owners are interested in building-related landscape, but they do not know specific management methods and leave the landscape space. The municipality needs to offer guidance on landscape architectural design and construction methods that the building owners can easily follow and to support the voluntary landscape space management on the part of the local residents by supporting the trees. Fifth, in order to improve the building-related landscape system, it is necessary to verify the effect of the building-related landscape and spread a consensus. At the government level, in order to enable building owners to recognize the value of the landscape space in connection with an urban regeneration project, it is necessary to present an example of an excellent building-related landscape installation via a pilot project.

The present study aims to develop measures to enhance user service at Chungnam Representative Library by establishing Chungnam Representative Library Operation Master Plan. To this end, I conducted a literature review, analysis of services of other representative libraries, and a survey. The study results suggested six measures for user service enhancement. The first measure is space-specific programs, such as children's materials room, general materials room, electronic materials room, auditorium, multipurpose room, outdoor stage, exhibition room, and book café. The second measure is the services specific user types, such as children, adolescents, adults, the disabled, and multicultural families. The third measure is information service specific for information type, such as print material service and digital material service. The fourth measure is the service for the Information-Poor including the expansion of mobile library service, the service for information users in special environment, and the development of mobile library rules. Fifth measure is information service for Chungcheongnam-do residents, such as Baekje Studies specialized service that incorporates local characteristics, specialized information service for Chungcheong Studies and local materials, and information service for administrative and policy materials. The last measure is the measure to secure initial users and early stage service enhancement.

The paper describes the history and the evolution of the conflict of the Saemangeum reclamation project, focusing on the court trial processes. The Saemangeum project is the world largest coastal reclamation work, regarded as the most controversial environmental issue in the recent history of Korea. Due to the severe pollution found in Lake Sihwa in 1996, the Saemangeum project began to receive a large degree of public concern on the water quality of the proposed artificial freshwater lake. Unlike the Sihwa case, the Korean court system intervened to resolve the heated conflicts between stakeholders in the Saemangeum case. Based on the same set of facts, the Korean courts showed different perspectives on the economic feasibility, value of the ecosystem, land use, and water quality, which represents the limit of legal system to address complicated environmental problems. After the final judgment by the Supreme Court, 'the Special Act for the promotion of the Saemangeum reclamation project', was enacted with strong political support from local leaders and congressmen. A more developmental-oriented land use plan came out in 2009 based on this Act. The Saemangeum project walked along the different pathway from the Sihwa case. The area should be managed in sustainable manners to appropriately consider conservation and development for the prosperity of local residents and future generations.
