Nowadays in offshore industry there are emerging hazards with vague property such as act of terrorism, act of war, unforeseen natural disasters such as tsunami, etc. Therefore industry professionals such as offshore energy insurers, safety engineers and risk managers in order to determine the failure rates and frequencies for the potential hazards where there is no data available, they need to use an appropriate method to overcome this difficulty. Furthermore in conventional risk based analysis models such as when using a fault tree analysis, hazards with vague properties are normally waived and ignored. In other word in previous situations only a traditional probability based fault tree analysis could be implemented. To overcome this shortcoming fuzzy set theory is applied to fault tree analysis to combine the known and unknown data in which the pre-combined result will be determined under a fuzzy environment. This has been fulfilled by integration of a generic bow-tie based risk analysis model into the risk assessment phase of the Risk Management (RM) cycles as a backbone of the phase. For this reason Fault Tree Analysis (FTA) and Event Tree Analysis (ETA) are used to analyse one of the significant risk factors associated in offshore terminals. This process will eventually help the insurers and risk managers in marine and offshore industries to investigate the potential hazards more in detail if there is vagueness. For this purpose a case study of offshore terminal while coinciding with the nature of the Caspian Sea was decided to be examined.

Purpose - This study presents strategies to overcome the COVID-19-induced crisis in Korea's meetings, incentives, conferences, and exhibitions (MICE) industry. It aims to quantitatively identify the environmental factors affecting the industry and their degree of influence, and derive optimal countermeasures. Design/methodology - The study applied the SWOT-AHP-TOWS framework. An AHP analysis was first performed within the SWOT frame, and then a TOWS analysis was conducted using the results of the SWOT-AHP analysis. In the AHP analysis, the number of pairwise comparison questions was limited to four for each SWOT factor to increase the consistency of responses by reducing the burden on respondents. Findings - The plunge in demand (threats factor) has had an overwhelming impact on the MICE industry, more than any other environmental factor. To overcome the crisis, the ST alternative that takes advantage of dynamic pop culture to minimize the business damage caused by the plunge in demand was the top priority measure. Based on the results, this study presents suggestions for overcoming the crisis in the MICE industry. First, the industry should develop profitable business models to supplement scarce financial resources by exploiting Korea's success with quarantine management. Second, the government must provide emergency relief funds or bailout support to protect MICE facilities and employees. Originality/value - Unlike previous work on the MICE industry, this study utilized the SWOT-AHPTOWS framework to derive quick research results in an abnormal situation. This approach can be expanded to other countries with different industrial environments and situations. Additionally, when applying this method to MICE sub-sectors, countermeasures should be tailored to each field.

Purpose: This study was performed to investigate the dietary behaviors and stress-related factors among male and female college students. Methods: A total of 405 college students (male-195, female-210) were recruited, of whom a questionnaire-based survey was conducted. The study investigated the general characteristics, health-related factors, dietary behaviors, and stress-related factors of the respondents. Results: The body mass index was significantly higher in males. The rates of underweight and overweight were significantly different between male and female respondents. The scores for workout frequency, health concerns and health condition were significantly higher in males, while the score for watching TV & playing computer games was significantly higher in females. The scores for meal regularity, frequency of breakfast consumption, and smoking were significantly higher in males. Eating problems showed a significant difference between males and females. The biggest source of stress was social factors, followed by college study and individual factors and the most experienced stress-induced symptom was anxiety, followed by headache and stomachache. The most popular way to overcome stress was taking a rest, followed by drinking & smoking and outdoor activity. The most preferred food under stressful conditions were alcohol or beverages, followed by hot & spicy food and sweet food, which showed a significant difference between males and females. Conclusion: These results indicate that stress affects dietary behaviors, drinking, smoking, and health status. Stress not only changes dietary behaviors, but is also related to health status. Therefore, it is necessary to develop appropriate programs for emotional stability and stress relief targeting college students which provide continuous nutrition education focused on desirable dietary behaviors and nutritional aspects.

Purpose: This study was conducted to determine the predictors of marriage outlook for university students in Korea. Method: A convenience sampling method was used and 438 university students were studied for final analysis. Data collection was conducted through the use of questionnaires which were constructed to include Marriage outlook scale, Family-of-origin Scale-55 and Sexual Knowledge & Attitude Test. Results: Marriage outlook for university students didn't demonstrate a positive point of view. There were positive correlations between marriage outlook, health of the family of origin and sexual awareness. The significant factors influencing marriage outlook of university students were current dating, health of the family of origin, gender, and religion. These factors explained 10.6% of marriage outlook of university students. Conclusions: These results support that special programs are needed in inducing a change in marriage outlook to overcome the low birthrate of Korea. These programs need to consider personal factors including the health of the family of origin, gender and religion.

In previous studies, the dynamic resistance, which was calculated by the process variables measured at the electrode of the welding machine, and the electrode displacement were used for quality exa mination. However, in-process usage of such systems is not effective in systems that include a welding gun attached to a robot. In order to overcome such problems, we obtained and used the process variables from the welding machine timer. This would allow us to estimate real time in -process weld quality. For quality estimation, the features were extracted as factors from the primary dynamic resistance patterns, which were measured in t he welding machine timer. The relationship between the indexes and nugget size of the welds was observed through the regression analysis. Using the analyzed factors, a regression model that could estimate nugget diameter was developed. Two regression equations of the model were suggested depending on the factors, and it was showed that the model developed by stepwise method was effective one for weld quality estimation. The developed estimation model was in good linearity with the nugget diameter obtained through the experimentation.

The purpose of this study is to investigate the effects of factors of family leisures on family intra-system dynamics and quality of family life. A total 309 questionnaires was analyzed from married men and women of school-age families. Factors of family leisures were classified in 'education oriented', 'hobby oriented', social oriented'and 'family oriented'in the study ahead.(Refer to Journal of korean Home Management association Vol. 19(2).) The major results of this research were as follows. First, family intra-system dynamics was classified 'individual progress', 'sentimental stability','interaction'and 'management efficiency'. Second, the group that participated more in 'social oriented'and less in 'family oriented'activities had higher level of 'individual progress'. The group that participated less in 'social oriented'and more in 'education oriented'activities had higher level of 'sentimental stability'The group that participated more in 'education oriented'activities had higher level of 'interaction'and 'management efficiency '. Based on the results as above, we suggest people need to overcome 'a mental panic'through the family leisure. And we need to develop concern with family leisure as a practical loaming.

Purpose: The purpose of this study was to explore nurses' experience of evidence-based nursing practice in general hospitals. Methods: Data were collected from 13 nurses through in-depth interviews about their experiences with evidence-based practice. The research questions were "What kind of evidence are you using in your practice?" and "What are the barriers to and enablers of evidence-based practice that you have experienced?" Qualitative data from field and transcribed notes were analyzed using qualitative content analysis methodology. Results: Major themes of using evidence were identified as 'research as primary valid evidence', 'information from local context and internet as realistic evidence', and 'clinical experience as pragmatic evidence'. Patient experience was not used as evidence in solving nursing problems. Barriers to and enablers of evidence-based practice were linked. They included both external, organizational factors and individual factors. Main issues were 'lack of evidence and poor work environment', and major facilitating factors were 'improving knowledge and skills related to evidence-based practice' and 'communicating and sharing evidence'. Conclusion: The study findings provide useful information for understanding nurses' experience of using external and internal evidence along with their meaning. A multidimensional approach is needed to overcome barriers to and implement evidence-based practice.
