As the number of ships and goods shipped by marine transportation increases, almost all shipping companies adopted foreign crews in order to overcome lack of seafarers and be competitive for manning cost. Thus, these days it is inevitable to work with foreign crews aboard ships, but there occur many marine accidents due to language barriers and communication problems under multicultural and multilingual shipboard environments. In order to resolve troubles resulting from different languages, reduce miscommunication risks, and make working on ships safe and efficient, this study recognized the current status of ships with mixed crews, analyzed marine accidents caused by communication problems not only in Korea but also in other countries using analytical methodologies. Additionally, existing hazards affecting miscommunication were identified and risk of miscommunication was quantitatively evaluated while offering suggestions and future forecasts. Consequently, in this study we suggested that fundamental dialogues are to be necessarily educated on the ships with foreign crews so as to reduce the language barrier and risk of miscommunication. Furthermore, a standard maritime Korean language program and manual targeting Korean coastal vessels would be developed in the next step.

Metabolic syndrome is the most important risk factors of cardiovascular diseases So, it is judged that Quality of life of persons with metabolic syndrome inevitably deteriorate. For the purpose, the study aims to analyse the number of risk factors, and the relationship between abnormality of each risk factor and Quality of life, targeting adult women aged more than 19. For this study, data from the National Health and Nutrition Behavior Survey in 2007 and 2008 were incorporated and 4,365 subjects were collected for the study. Version 17.0 SPSS was used for data analysis. Statistical significance was defined as p<0.05. As a result of the study, the prevalence rate of metabolic syndrome was 24.2%. According to the number of risk factors of metabolic syndrome the regression coefficient of Quality of life was -0.024 when the number of risk factor was one, -0.048 when there were two risk factors, -0.090 when there were three risk factors, -0.117 when there were four risk factors, and -0.168 when there were five risk factors. The regression coefficient(abnormal/normal)of risk factors of metabolic syndrome were as follows; Waist circumference -0.035, Blood pressure was -0.064, Fasting glucose was -0,026 and HDL cholesterol was -0.012. In conclusion, as it was discovered that risk factors of metabolic syndrome had significant relations with Quality of life, it is suggested that the relations between some significant variables and Quality of life should be actively considered so that adult women can perceive metabolic syndrome properly and endeavor to improve their Quality of life.

As a result of the fast development of Information communication technology, the competitive advantage of companies and the service quality of nonprofit organizations has been largely changed. Corresponding to this kind of change, companies have tried to make production improvement, competitive strengthening, and organizational innovation. Meanwhile, the nonprofit organizations directed by the government are pursuing the service innovation from general administration area to the public service for civilians. In relation to this, risk management of the company's information systems outsourcing has largely been studied until now. However, the study of risk management for nonprofit organization information systems outsourcing has rarely been made. In this paper, to provide the theoretical base for further research, we have attempted to develop the evaluation framework for risk management of information systems outsourcing considering the characteristics of nonprofit organizations.

Inflammation is one mechanism through which cancer is initiated and progresses, and is implicated in the etiology of other conditions that affect cancer risk and prognosis, such as type 2 diabetes, cardiovascular disease, and visceral obesity. Emerging human evidence, primarily epidemiological, suggests that walnuts impact risk of these chronic diseases via inflammation. The published literature documents associations between walnut consumption and reduced risk of cancer, and mortality from cancer, diabetes, and cardiovascular disease, particularly within the context of the Mediterranean Diet. While encouraging, follow-up in human intervention trials is needed to better elucidate any potential cancer prevention effect of walnuts, per se. In humans, the far-reaching positive effects of a plant-based diet that includes walnuts may be the most critical message for the public. Indeed, appropriate translation of nutrition research is essential for facilitating healthful consumer dietary behavior. This paper will explore the translation and application of human evidence regarding connections with cancer and biomarkers of inflammation to the development of dietary guidance for the public and individualized dietary advice. Strategies for encouraging dietary patterns that may reduce cancer risk will be explored.

This study is to evaluate the risk perception of noise of the ground-crews in the Korean airbases who exposed to noise of jet plane. 1148 ground-crews and 231 pilots of 2 airbases participated in this study. The questionnaires of risk perception with visual analogue scale were completed by the participants. For comparison, the perception of other risks such as beef contaminated with dioxin, AIDS, lung cancer, otitis media, shigellosis, driving, drinking, and smoking were also included in the questionnaire of risk perception. The results of this study suggested the necessity of risk communication about noise and activation of effective hearing conservation program in the Korean air-force.

This study aims to investigate the antecedent of consumer personal preventive equipment purchase behaviour by extending the HBM model after the pandemic. Pandemic related studies have focused on the effect of perceived susceptibility and perceived severity on consumer preventive behaviour, little studies have investigated the antecedents of consumer perceived risk. This study filled the gaps in the previous studies. This study tested all proposed hypotheses among users who have purchase the self-preventive behaviour. In final 253 valid data were collected through online survey for statistics analysis. This study found that consumer's health consciousness significantly impacted consumer's perceived severity of COVID-19 and perceived risk. Perceived risk positively impacted consumer self-preventive equipment purchase intention. In contrast, perceived susceptibility did not significantly consumer perceived risk. Based on these results, the theoretical implication will be offered on the study of health-related studies and will be given insight for disease control center to effectively manage consumer self-preventive behaviour.

In this paper, we design a smart factory risk improvement system and risk improvement method using AI edge devices. The smart factory risk improvement system collects, analyzes, prevents, and promptly responds to the worker's work performance process in the smart factory using AI edge devices, and can reduce the risk that may occur during work with improving the defect rate when workers perfom jobs. In particular, based on worker image information, worker biometric information, equipment operation information, and quality information of manufactured products, it is possible to set an abnormal risk condition, and it is possible to improve the risk so that the work is efficient and for the accurate performance. In addition, all data collected from cameras and IoT sensors inside the smart factory are processed by the AI edge device instead of all data being sent to the cloud, and only necessary data can be transmitted to the cloud, so the processing speed is fast and it has the advantage that security problems are low. Additionally, the use of AI edge devices has the advantage of reducing of data communication costs and the costs of data transmission bandwidth acquisition due to decrease of the amount of data transmission to the cloud.

The study on the duration of risk in the marine insurance has been paid a great attention because the marine insurance has to provide several indemnity conditions including the one to be compensated the loss when the accident happens. The research examines as to how the duration of risk has been extended from the beginning period to now. The results show the duration of risk has been continually extended in terms of place and time by a dramatic change of environment related to the marine insurance including marine transportation, a variety of goods, development of marine communication, many different trading conditions, etc, and requirement of the assured. The validity of the duration of risk is effected when the ship leaves at the port and is terminated when the ship arrives at the final destination. It in the Lloyd's age has been started when the products was charged to the ship and terminated when the one was safely discharged to the destination. Recently, the duration of risk in England Marine Insurance attaches from the time the goods leave the warehouse or place of storage at the placed named for the commencement of the transit, continues during the ordinary course of transit and terminates on delivery to the consignees or other final warehouse or place of storage at the destination named. Further research on the extension of the duration of risk must be conducted according to the being large scale of the ship and goods.
