  • Accidents associated with hazardous materials, including oil and HNS, in maritime transportation show increasing trend. Therefore, preventive countermeasures for such accidents should be provided. The purpose of this study is to analyze level of risk on human loss and potential damage to environment, using data on domestic marine accidents carrying hazardous materials (2002~2014), and identify high-risk accident types for urgent risk management which needs findings of accident causes and proper mitigation measures. High-risks on human loss are explosion and suffocation, occurred in process of ship maintenance and tank cleaning. On the other hand, high-risk on environmental damage is spill caused by ship accidents (collision, grounding and etc.). Especially, spill occurs during loading operation of oil and HNS onboard a ship. Strict operation supervision/management and safety education/training on a regular basis could prevent accidents, because human factors such as not wearing safety gear and careless cargo handling cause most of the marine accidents.

  • Given the rapid development of information and communication technology (ICT) and the deepening of the information gap phenomenon in the context of the COVID-19 pandemic, researchers and practitioners need to understand the changing perceptions of new phenomena such as COVID-19 information gap on the existing information-vulnerable population. In this study, an empirical analysis was performed with the digital information gap survey data in 2020 to understand the potential impact of COVID-19 on the information gap according to the information-vulnerable class. This study is to verify the effect of information gap, marginalized groups, gender, and major factors of information services (contents, social relations, life services, information production, networking, social participation, non-face-to-face services) on the change in perception of digital information technology after Corona. Hierarchical regression analysis was performed. As a result of the analysis, it was found that the higher the content, social relationship, life service, networking, and digital non-face-to-face service, the higher the change in perception of digital information technology after Corona. Therefore, in light of the evolving phenomenon of COVID-19, it is considered that the government needs to provide education and training to strengthen the capabilities of the information-vulnerable class in order to resolve the digital information gap.

  • Objectives: We aimed to examine the association between the relative preference for vegetables and meat and cancer incidence, in a population-based retrospective cohort in Korea. Methods: We included 10,148,131 participants (5,794,124 men; 4,354,007 women) who underwent national health screening between 2004 and 2005 from the National Health Information Database of the National Health Insurance Service (NHIS-NHID). Participants were asked whether they preferred consuming 1) vegetables more often, 2) both vegetables and meat or 3) meat more often. Participants were followed up to Dec. 31, 2017. All cancer and eighteen common cancer cases were identified through the code from the International Classification of Diseases, 10th revision. We estimated sex-specific relative risks and 95% confidence intervals, adjusting for age, body mass index, alcohol consumption, smoking, physical activity, and income level. Results: During an average follow-up of 12.4 years, 714,170 cancer cases were documented. In men, consuming meat more often was associated with lower risk of esophageal, liver, and stomach cancers, but higher risk of lung and kidney cancers. Consuming both vegetables and meat was associated with higher risk of prostate cancer, but with lower risk of esophageal, liver, and stomach cancers in men. In women, consuming meat more often was associated with a higher risk of colorectal cancer and breast, endometrial, and cervical cancers diagnosed before the age of 50. Consuming both vegetables and meat was associated with lower risk of liver cancer in women. Conclusions: Our study suggests a potential link between vegetable and meat intake and cancer incidence in the Korean population. Further investigation on the association between the intake of specific types of vegetables and meat and cancer risk in Korean prospective cohort studies is needed.

  • The purpose of this research is to analyze the Spill-over economic effect of the cultural and creative industries(CCI) in Henan Province, China. The research object is the CCI of Henan Province, which is mainly based on five sectors out of 42 industries in the industrial association table of the Statistical Bureau of Henan Province, China in 2017 (culture, sports; recreation and research sector; experimental development and integrated technical services sector; information transmission, computer services and software sector; education sector, etc), and is analyzed through secondary integration and redefinition of the CCI of Henan Province. Through the analysis of Henan Province Industry Association Table, this paper provides some enlightenment to the future direction of the cultural and creative industries. The main analysis results are as follows. The total production inducement of the CCI in Henan province is 48,848 billion yuan, and in particular, the production inducement coefficient of the industry in Henan province is 2.72809, 2.23909 (total of columns and rows), Index of the power of dispersion is 0.26325, and the index of the sensitivity of dispersion is 0.87535. Income induction coefficient is 0.55211, production tax induction coefficient is 0.09291. Because CCI of Henan Province has full development potential, the government needs to provide active support and policy support, in addition to the need for legal provisions and supervision of market management. In order to improve the innovative development of the CCI, it is necessary to develop a new model of "CCI+X".

  • Objectives: Stress is a psychological reaction to stimuli such as anxiety or threat felt by a person either physically or mentally when placed in a difficult situation. Although a relationship between stress and dry mouth has been reported, it remains understudied. The purpose of this study was to investigate the association between stress and subjective dry mouth among the elderly living in a rural region. Methods: A total of 214 people aged ${\geq}60years$ living in a rural area were recruited with an informed consent for a cross-sectional analysis. Information about stress and subjective dry mouth was obtained by an interview survey with a constructed questionnaire. Data on other potential confounding factors (including oral factors) such as socio-demographic data, health-related behaviors, the number of remaining teeth, and subjective chewing ability were also gathered at the same time. Logistic regression models were used to analyze the relationship of stress and dry mouth using SPSS. Results: The Crude odds ratio (OR) of stress awareness affecting subjective dry mouth was 2.59 (95% confidence interval: 1.43-4.68). After adjusting for sex, education, income, smoking, and alcohol intake, the adjusted OR was 2.52 (95% confidence interval: 1.30-4.87) which was statistically significant. Conclusions: Elderly people who were stressed had an approximately 2-fold increase in experiencing subjective dry mouth when compared to their stress-free counterparts.

  • Focusing on the potential impact of information and communication technology (ICT) on older adults' quality of life, this study empirically examined the influence of smartphone use in old age on life satisfaction, depression, social activity and social support of Korean older adults. In order to examine the effects of smartphone use, this study analyzed data from 630 questionnaire surveys from older adults aged 65 and over living in Seoul. The effects of smartphone use were tested using hierarchical multiple regression analysis, controlling for socio-demographic variables such as age, sex, spouse, education and income. Results showed that the effects of smartphone use on life satisfaction, depression and social activity of older adults were statistically significant. However, the effects of smartphone use on social support of older adults was not statistically significant. This study suggests that ICT such as smartphones in old age plays generally positive roles in enhancing psychological, mental and social aspects of quality of life. This implies that further practical efforts to expand the distribution and use of ICT in old age are required to improve quality of life and successful aging of older adults.

  • BACKGROUND/OBJECTIVE: The honeysuckle berry (HB) contains ascorbic acid and phenolic components, especially anthocyanins, flavonoids, and low-molecular-weight phenolic acids. In order to examine the potential of HB as a hepatoprotective medicinal food, we evaluated the in vitro anti-oxidant and anti-inflammatory activities of Korean HB (HBK) and Chinese HB (HBC). MATERIALS/METHODS: Antioxidant and anti-inflammatory effects of the extracts were examined in HepG2 and RAW 264.7 cells, respectively. The anti-oxidant capacity was determined by DPPH, SOD, CAT, and ARE luciferase activities. The production of nitric oxide (NO) as an inflammatory marker was also evaluated. The Nrf2-mediated mRNA levels of heme oxygenase-1 (HO-1), NAD(P)H dehydrogenase [quinone] 1 (Nqo1), and glutamate-cysteine ligase catalytic subunit (Gclc) were measured. The concentrations of HB extracts used were 3, 10, 30, 100, and $300{\mu}g/mL$. RESULTS: The radical scavenging activity of all HB extracts increased in a concentration-dependent manner (P < 0.01 or P < 0.05). SOD (P < 0.05) and CAT (P < 0.01) activities were increased by treatment with $300{\mu}g/mL$ of each HB extract, when compared to those in the control. NO production was observed in cells pretreated with 100 or $300{\mu}g/mL$ of HBC and HBK (P < 0.01). Treatment with $300{\mu}g/mL$ of HBC significantly increased Nqo1 (P < 0.01) and Gclc (P < 0.05) mRNA levels compared to those in the control. Treatment with $300{\mu}g/mL$ of HBK (P < 0.05) and HBC (P < 0.01) also significantly increased the HO-1 mRNA level compared to that in the control. CONCLUSIONS: Thus, the Korean and Chinese HBs were found to possess favorable in vitro anti-oxidant and anti-inflammatory activities. Nrf2 and its related anti-oxidant genes were associated with both anti-oxidant and anti-inflammatory activities in HB-treated cells. Further studies are needed to confirm these in vivo effects.

  • Objectives: This study was conducted to investigate the emotional characteristics of the patients within one year after stroke using the Core Seven Emotions Inventory-Short Form. Methods: It analyzed the medical records of 39 stroke patients who had visited W University hospital and completed the Core Seven-Emotions Inventory-Short Form (CSEI-S), the K-MBI, the PWI-SF, and the HADS. Patients data were analyzed by descriptive analysis, frequency analysis, the Mann-Whitney U test, and the nonparametric test of the CSEI according to the period of stroke onset in patients and Spearman's correlation analysis using the SPSS (Statistical Package for the Social Science, IBM, United States of America) Version 23.0. Results: First, in the case of depression, all subjects were in the danger group, although more than half of the joy, anger, thinking, sadness and fear were included in the normal group in the shortening of the key seven-point scale. Secondly, in measuring the social and psychological stress and hospital anxiety and depression, social and psychological stress were indicated to be a potential danger group, while anxiety and depression were shown to be a healthy group. Thirdly, the emotional characteristics were explored according to the sub-factor of the shortening of the key seven-figure emotional scale after being classified within two months, between two and six months and over six months depending on the duration of the outbreak. As a result, statistically significant, Joy was the highest score over six months and the lowest score between two and six months. On the other hand, the case of depression was depicted to be significantly lower at over six months, and was highest between two and six months. Finally, the correlations on each scale were statistically significant. Conclusions: This study provided that the CSEI-S can be used to simply to measure the emotions of patients according to the period of the onset of stroke in the clinical scene.

  • There is a growing interest in the entrepreneurial activity that has long been considered essential for sustainable economic development and value creating. Although it is strongly encouraged by focusing on the positive aspects of venturing, less has been paid attention to entrepreneurial failure, which is the biggest cause of hesitation in starting a business. The uncertain and risky nature of entrepreneurship implies a considerable possibility of failure. Even if it fails, the experience and knowledge of entrepreneurs acquired through entrepreneurship indeed offers valuable lessons for the re-venturing, which can serve as an important social asset that should not be lost. It has been argued that re-entering the same industry for the subsequent venture maximizes the learning effect through utilizing potential benefits from industry-specific knowledge. Although the re-startup after entrepreneurial failure is a very important topic in the studies on serial entrepreneurs, there is a paucity of systematic empirical investigation. This study responds to calls for more research on the re-startup after entrepreneurial failure, and specifically complements existing studies on serial entrepreneurs. Focusing on the entrepreneurs' attribution for the failure, we conducted an empirical analysis of how this affects the re-startup process. Moreover, we also examined the moderating effects of entrepreneurial self-efficacy and resilience. For the analyses, we surveyed the entrepreneurs who tried to re-start the subsequent business after the entrepreneurial failure through the "Revitalization Center for Strained Entrepreneur". The results found that failed entrepreneurs who blamed internal factors for their previous venture failures were likely to keep the same industry for their subsequent business. In addition, the positive effect of internal attribution on maintaining the same industry for the re-startup was found to be stronger when entrepreneurial self-efficacy and resilience were high.
