The development of the aviation industry and the changes in the military operation mission environment are demanding more long - distance operation (long - time flight), and such a flying environment is a risk factor for fatigue - related accidents. For the aviation related organizations such as ICAO and FAA, fatigue risk management system (FRMS) are applied along with flight time restriction regulations to prevent fatigue related accidents. The most important process in FRMS is fatigue risk management. Fatigue risk management systematically manages fatigue through scientific fatigue risk data collection and fatigue risk assessment. The purpose of this study is to applicate the assessment of scientific fatigue risk management to pilots of airplanes engaged in long flight. We reviewed the current state of risk management and FRMS through previous research. We also developed fatigue risk management indicators and examined the validity of internationally recognized fatigue risk data collection methods and fatigue risk assessment tools. There are 134 mission (flight) data used for development. In order to verify the indicators, the fatigue risk score between the items was assigned through pair-wise comparison. In addition, the verify test results were normalized.

Purpose: It is crucial that 119 emergency medical technician (EMT) have adequate knowledge regarding forensic science. This study aimed to assess the forensic knowledge of EMTs in the Republic of Korea. Methods: This study was conducted on EMTs of five fire stations in D metropolitan city between August 6 and August 13, 2018. A questionnaire consisting of items on crime-related incident recognition (i.e., mechanical asphyxiation, trauma, sex crimes, and child abuse), forensic evidence management (i.e., evidence collection, preservation, and recording) was administered to the participants. Finally, 119 questionnaires were analyzed. Results: The ratio of correct answers for crime-related incidents recognition was 55.82%, which was lower than that for forensic evidence management(84.5%). In particular, the scores for the type of neck compression(16.5%) and wound assessment(44.0%) were low. The percentage of correct answers for forensic evidence management was 78.4% for evidence collection, 84.4% for evidence preservation, and 90.6% for evidence recording. Previous forensic education experience was not a significant variable. Conclusion: Specific and practical forensic science education on perception of crime-related incident, including asphyxia and wound identification, and forensic evidence collection is needed.

In this study, samples were collected from various ancient wooden shipwrecks, including the Shinan shipwreck and Jindo shipwreck that used iron nails, the Yeongheungdo shipwreck carrying iron artifacts, as well as the Sibidongpado shipwreck and Wando shipwreck where degradation products were not observed, all of which were salvaged by the National Research Institute of Maritime Heritage. The aim was to analyze the characteristics of degradation products generated by iron (Fe) within the salvaged wooden shipwreck materials and establish fundamental data on degradation products in waterlogged archaeological wood. The analysis revealed that sulfur (S) is generally accumulated in wood obtained from marine environments. It was observed that the content of inorganic substances such as iron and sulfur was significantly higher in the Shinan shipwreck, Jindo shipwreck, and Yeongheungdo shipwreck compared to Sibidongpado shipwreck and Wando shipwreck, which used wooden nails. This indicates that the presence of iron affects the accumulation of degradation products and suggests that iron is a factor in the corrosion of wood. Furthermore, crystallin compounds were observed within the cell walls, and higher concentrations of iron and sulfur were found in the resin ducts, rays, and radial tissues. This suggests that during desalination and consolidation treatments, warm water or polyethylene glycol (PEG) may move degradation factors into resincanals, rays, radial tissues, etc.

The donation collection system to secure infrastructure and land necessary for public development projects has been actively applied as an effective means of realizing public interest and the concept of recovering development profits, and has contributed greatly to society in public difficult financial conditions. However, due to the ambiguous legal standards and lack of legal grounds for the operation of the donation collection system, it has been arbitrarily used for administrative convenience in the form of granting a donation collection assistant to install infrastructure. In addition, infrastructure is a facility that is constructed and donated within development profits to obtain licenses, and is promoted to minimize construction costs to improve profitability, posing a risk of poor infrastructure planning, design, and construction, resulting in increased safety and maintenance costs for citizens. Continuous system and legal improvement are needed to improve the excellence, convenience, and safety of facilities that citizens will use for half a century through the improvement of the donation system.

A considerable number of construction disasters occurs on pathway. A safety management in construction sites is usually performed to prevent accidents in activity areas. This means that safety management level of hazards on pathway is relatively minified. Many researchers have introduced that a hazard identification is fundamental of safety management. Thus, algorithms for helping safety managers' hazardous area identification is developed using automated data collection technology. These algorithms primarily search potential hazardous area by comparing workers' location logs based on real-time locating system and optimal routes based on BIM. And potential hazardous areas is filtered by identified hazardous areas and activity areas. After that, safety managers are provided with information about potential hazardous areas and can establish proper safety countermeasures. This can help improving safety in construction sites.

Since the use of plastics in various goods such as film, containers, and packaging has been increasing in Korea, the generation of plastic waste is increasing. Plastic wastes are managed by waste charge system, Extended Producer Responsibility (EPR) system and voluntary agreement of plastic waste collection-recycling system. Recently, the management of plastic waste is becoming a social issues due to the refusal of the collection of plastic waste including waste plastic bag and waste vinyl. The ministry of environment in korea was set up the comprehensive plan for recycling waste management in accordance with the circulation cycle of manufacturing and production - distribution and consumption - separate and discharge - collection and sorting - recycling. In this study, the improvements for management of plastic waste were suggested with the review of domestic waste plastics management and the comprehensive plan by the ministry of environment.

In recent years, for the purpose of solving the problem regarding environment protection and resource saving, certain measures and policies have been promoted to establish a green supply chains (GSC) with material flows from collection of used products to reuse of recycled parts in production of products. In this study, we propose an optimal operation of the GSC while considering the collection incentive of the used products and quality for recycling of used products. Two types of decision-making approaches are used for product quantity, collection incentive of used products and lower limit of quality level of reusable parts in the used products for recycling in the GSC. One is the decision-making under an independent policy in decentralized supply chains where a retailer and a manufacturer make decisions so as to maximize profits individually. The other is the decision-making under a cooperative policy in centralized supply chains where a retailer and a manufacturer make decisions cooperatively so as to maximize the whole system's profit. Additionally, we also discuss supply chain coordination as a manufacturer-retailer partnership based on profit sharing. Furthermore, we show the effect of the quality of the reusable parts on the optimal decisions. The collection incentive of the used products was found to bring more profitability to the GSC activity.

Wireless sensor networks (WSNs) are used to collect various data in environment monitoring applications. A spatial clustering may reduce energy consumption of data collection by partitioning the WSN into a set of spatial clusters with similar sensing data. For each cluster, only a few sensor nodes (samplers) report their sensing data to a base station (BS). The BS may predict the missed data of non-samplers using the spatial correlations between sensor nodes. ASAP is a representative data collection algorithm using the spatial clustering. It periodically reconstructs the entire network into new clusters to accommodate to the change of spatial correlations, which results in high message overhead. In this paper, we propose a new data collection algorithm, name EPDC (Energy-efficient Periodic Data Collection). Unlike ASAP, EPDC identifies a specific cluster consisting of many dissimilar sensor nodes. Then it reconstructs only the cluster into subclusters each of which includes strongly correlated sensor nodes. EPDC also tries to reduce the message overhead by incorporating a judicious probabilistic model transfer method. We evaluate the performance of EPDC and ASAP using a simulation model. The experiment results show that the performance improvement of EPDC is up to 84% compared to ASAP.
