When those who have caused a fire have no ability to compensate fire victims, the victims tend to charge fire agencies for state compensation to receive damage relief. This study analyzed two state compensation cases related to fires. The findings suggest that if there is a causal relationship between fire damage and mistakes committed by fire officials that are associated with fire prevention or special fire inspections, courts usually decide that fire agencies should compensate fire victims. Despite the introduction of a new article in the Framework Act on Fire-Fighting Services on December 26, 2017, titled "Exemption from Responsibility for Fire-Fighting Activities", exemptions are only available if inevitability of the activity has been proven. However, unlike rescue or first aid activity, inevitability is difficult to prove when it comes to fire inspection activity. Therefore, it is expected that state compensation suits related to fires will not decrease.

Background: The purpose of this study is to provide the data for discussions related to oral health promotion policies for single-person households by analyzing the status of unmet dental needs and related factors in single-person households in Korea, based on the Anderson model. Methods: The data, obtained from 544 single-person households of those over 20 years old who were targeted for the 6th Korea National Health and Nutrition Examination Survey, were analyzed through a complex sample frequency analysis, complex sample cross analysis (Rao-Scott chi-square test), and complex sample binary logistic regression analysis on a complex sampling design. Results: The most frequently given reason for an unmet dental need among single-person households was economic (52.4%). Factors related to the unmet dental needs of single-person households are smoking, which is a predisposing factor; personal income levels, which are an enabling factor; chewing discomfort; and limited daily activities, which are need factors. Smokers, the high-income group, the chewing-discomfort group, and the limited activity group showed high unmet dental care experience. Smokers had a 2.75 times higher rate of unmet dental care than non-smokers, and the high-income group had a 5.29 times higher rate of unmet dental needs than the median group. The rate of unmet dental needs for the chewing discomfort group was 3.27 times higher than the non-chewing discomfort group, and the limited activity group had a 7.87 times higher rate of unmet dental needs than the non-limited activity group. Conclusion: It is necessary to map out policies designed to help maintain and promote met dental needs considered to be internally heterogeneous to single-person householders, based on the Anderson model.

The impact of supervisory communication apprehension (SCA) on subordinates' job performance was investigated in this study. We also examined the impact of task-related uncertainty in mediating the relationship between SCA and subordinate work performance, as well as the role of information-seeking behavior in moderating the relationship between task-related uncertainty and subordinate job performance. A sample of subordinates and their supervisors from public and private sector enterprises in Pakistan were used in the study. The concept of communication apprehension is not limited to a single organization or industry, and the conditions suggest that apprehensive supervisors are likely to exist in different organizations and industries in Pakistan, including banks, telecommunications, and development sector organizations. Company directors and leaders of human resources departments were contacted to reach out to possible respondents. SmartPLS software was used to evaluate the data using a structural equation modeling technique which is commonly used in explanatory studies (Atta et al., 2021). We found evidence to support ideas predicting the association between SCA and subordinate job performance, as well as the mediating role of task-related ambiguity in the relationship. Furthermore, the findings show that information-seeking activity has a moderating effect on the link between task-related ambiguity and subordinate job performance. This is one of the first studies to look at major mediating and moderating mechanisms in the link between SCA and subordinate job performance.

This study is to observe the effect of oral health of elderly on overall health status and social activity to provide basic data for oral health improvement program for the elderly and development of related policies. The survey was conducted from July 25th to July 29th, 2011, and used 145 copies for this research analysis. As a result of correlation analysis, it is observed that all of 4 sub factors of Geriatric Oral Health Assessment Index have significant static correlation with overall health status of elderly and social activity also has significant static correlation with oral health. As a result of regression analysis, the functional limitation out of sub factors showed significant positive effect on health status and psychological effect has significant positive effect on social activity. Based on the above result, it is observed that, at the time of rapidly entering to an aging society, the life quality related to oral health of elderly which is part of overall health and overall health status and social activity areas that are recognized by the elderly have significant correlation. And, it is important to understand the factors of oral health affecting health status and social activity. Based on the result of this study, more researches on the development of oral health program and development of assessment tool that can be easily employed should be made.

Understanding how and why people differ is a fundamental, if distant, goal of research efforts to bridge psychological and biological levels of analysis. General fluid intelligence (gF) is a major dimension of individual differences and refers to reasoning and novel problemsolving ability. A conceptual integration of evidence from cognitive (behavioral) and anatomical studies suggeststhat gF should covary with both task performance and neural activity in specific brain systems when specific cognitive demands are present, with the neural activity mediating the relation between gF and performance. Direct investigation of this possibility will be a critical step toward a mechanistic model of human intelligence. In turn, a mechanistic model might suggest ways to enhance gF through targeted behavioral or neurobiological intervent ions, We formed two different groups as subjects based on their scholarly attainments. Each group consists of 20 volunteers(aged 16-17 years, right-handed males) from the National Gifted School and a local high school respectively. To test whether individual differences in general intelligence are mediated at a neural level, we first assessed intellectual characteristics in 40 subjects using standard intelligence tests (Raven's Advanced Progressive Matrices, Wechsler Adult Intelligence Scale, Torrance Tests of Creative Thinking) administered outside of the MR scanner. We then used functional magnetic resonance imaging (fMRl) to measure task-related brain activity as participants performed three different kinds of computerized reasoning tasks that were intended to activate the relevant neural systems. To examine the difference of neural activity according to discrepancy in general intelligence, we compared the brain activity of both extreme groups (each, n=10) of the participants based on the standard intelligence test scores. In contrast to the common expectation, there was no significant difference of brain region involved in high-g tasks between both groups. Random effect analysis exhibited that lateral prefrontal, anterior cingulate and parietal cortex are associated with gF. Despite very different task contents in the three high-g-low-g contrasts, recruitment of multiple regions is markedly similar in each case, However, on the task with high 9F correlations, the Prodigy group, (intelligence rank: >99%) showed higher task-related neural activity in several brain regions. These results suggest that the relationship between gF and brain activity should be stronger under high-g conditions than low-g conditions.

Cadmium (Cd) and tributyltin (TBT) are common contaminants of marine and freshwater ecosystems, and can induce the formation of reactive oxygen species (ROS). These ROS can, in turn, cause oxidative stress. In the present study, we investigated time-related effects of Cd (0.05 and 0.1 ppm) and TBT (5 and 10 ppb) treatment on antioxidant enzyme activity, i.e., the activity of superoxide dismutase (SOD) and catalase (CAT) in the gills and digestive glands of the ark shell, Scapharca broughtonii. In addition, hydrogen peroxide ($H_2O_2$) concentrations, lysozyme activity, and glutamate oxaloacetate transaminase (GOT) and glutamate pyruvate transaminase (GPT) levels were measured in the hemolymph. We found that Cd and TBT treatment significantly increased antioxidant enzyme mRNA expression and activity in the digestive glands and gills in a time-dependent manner. In response to the Cd and TBT treatments, antioxidant enzymes mRNA expression and activity increased up to day 5 in the digestive glands and then decreased by day 7. In the gills, antioxidant enzymes mRNA expression and activity increased up to day 3 and then decreased by day 5. Likewise, $H_2O_2$ concentrations significantly increased up to day 5 and then decreased by day 7. Finally, lysozyme activity decreased during the experimental period, whereas GOT and GPT levels were significantly increased in a time-dependent manner. These results suggest that antioxidant enzymes play an important role in decreasing ROS levels and oxidative stress in ark shells exposed to Cd and TBT.

Purpose: This study examined the effects of a physical activity promoting program based on the Information-Motivation-Behavioral Skills (IMB) model on physical activity and health outcomes among obese older adults with knee osteoarthritis. Methods: This study utilized a randomized controlled trial with a convenience sample of 75 obese older adults with knee osteoarthritis in a university hospital. The older adults in the intervention group participated in a 12-week program involving weekly group sessions and monitoring calls with education booklets and video clips for exercise dances, while those in the control group received an usual care. Outcomes were measured using self-report questionnaires, anthropometrics, and blood analyses. The intervention effects were analyzed using Mann-Whitney U test and ANCOVA. Results: The mean age of participants was 74.9 years with 84.0% women. The intervention group at 12 weeks showed significantly greater improvements in self-efficacy for physical activity (F=81.92, p<.001), physical activity amounts (Z=-2.21, p=.044), knee joint function (F=15.88, p<.001), and health-related quality of life (F=14.89, p<.001) compared to the control group. Among obese-metabolic outcomes, the intervention group at 12 weeks showed a significant decrease in visceral fat mass (F=7.57, p=.008) and improvement in high-density level cholesterol (F=9.51, p=.003) compared to the control group. Conclusion: Study findings support the need for an IMB based physical activity program for promoting physical activity, knee function and health outcomes in obese older adults with knee osteoarthritis. Longitudinal studies are warranted to confirm the persistence of obese-metabolic effects in clinical settings.

We previously reported that fermentation by Lactobacillus brevis LB-20 isolated from Kimchi resulted in improvement of the sensory quality of Hizikia fusiforme water extract. This study was conducted to evaluate the possible application of lactic acid bacteria fermentation to improve the functional qualities of H. fusiforme extract. L. brevis LB-20 was inoculated and cultivated in H. fusiforme extract. The antioxidant and anti-inflammatory activities of extract were then assayed both before and following fermentation for two days. Antioxidant activity was determined by assaying levels of radical scavenging activity against 1,1-diphenyl-2-picrylhydrazyl (DPPH), hydroxyl, superoxide, and alkyl radical. Lactic acid bacterial fermentation of H. fusiforme extract resulted in enhancement of antioxidant activity. The greatest enhancement of antioxidant activity was seen in the hydroxyl radical scavenging assay that incorporated 0.5 mg/mL of raw and fermented H. fusiforme extract. Fermented extract exhibited greater (21.95%) inhibition of nitric oxide synthesis than did raw extract (14.66%) at a concentration of 1 mg/mL. The fermented extract exerted its potent anti-inflammatory activity via attenuation of expression of inflammation-related cytokine proteins (TNF-${\alpha}$ and iNOS).

Saururus chinensis has long been widely used in oriental folk medicines to treat diseases. In the current study, organic solvent fractions obtained from the main methanolic extract of S chinensis were evaluated for their antioxidative and related physiological activities. The antioxidant activity of the fractions was measured using DPPH free radical scavenging activity, increased in a dose-dependent manner, and the $ED_{50}$ of the ethyl acetate fractions exhibited a value of 12.84 ${\mu}g/ml$ higher than 27.22 ${\mu}g/ml$ compared to the BHT. Also, the cell viability of S. chinensis on $H_2O_2$-induced HDF cell death ($IC_{50}$) showed the highest cell viability of 89.39% in 50 ${\mu}g/ml$ of ethyl acetate fraction and 67.98% of visible cell survival rate in n-butanolic fraction. Meanwhile, all fractions of the S. chinensis extract led to a slight down regulation of the mRNA expression of fibulin-5, which is related to skin elasticity, and the ethyl acetate fraction having high antioxidant activity showed a markedly inhibitory effect on chick embryonic angiogenesis using the CAM assay. These results suggest that the ethyl acetate fraction of S. chinensis extract could be a good material in therapeutic application for antioxidant and related anti-angiogenesis activities.
