The Korea Convergence Society. The aim of this study was to evaluate the association between alcohol consumption and periodontal diseases in Korea adults. The date from the 2014 Korean National Health and Nutrition Survey were used, and 4,328 subjects over 30 years were included in the analysis. Periodontal disease was assessed using the Community Periodontal Index. The adjusted odds ratio of drinking experience, drinking frequency, the drinking amount and the drinking duration were calculated from the logistic regression model with the never-drinkers as a reference group and the logistic model controlled for age, gender, education, and diabetes. This study found that the risk of periodontal disease according to the drinking status of adults over 30 years of age was 1.39 times (95% CI=1.01-1.90) higher than that of non-drinking group when the number of drinks consumed at one time was more than seven glasses. The frequency of binge alcohol consumption, amount of alcohol consumption and duration of alcohol consumption were significantly associated with the risk of periodontal disease in a dose-response pattern among over 30 years. Alcohol consumption was discovered to be a potential risk indicator for periodontitis. Dental practitioners need to be aware that patients who drink may be at higher risk of periodontitis and could benefit from advice to quit drinking and maintain regular dental visits.

This paper predict user acceptance of smart clothing. The present research develops and validates new products for smart clothing. Studies suggest that further analysis of the process be undertaken to better establish properties for smart clothing, underlying structures and stability over innovative technologies. The findings reported in this paper should be useful methods which identify user needs. such findings in now provide a way to explain technology acceptance. Both of qualitative and quantitative methods, were applied to this study in order to find out user needs for smart clothing. We are writing scenarios and conducting both focused group interviews and a survey to assess the user's interest. The purpose of the survey is to evaluate the importance of the functions and to evaluate the degree of the participant's feeling and attitude. Furthermore, we explore the nature and specific influences of factors that may affect the user perception and usage.

A survey was conducted to investigate the attitudes of the food specialist to the food developed by gene recombination. The mail survey was distributed to 1,400 food specialists and received 464, a response rate of 33.1%. Respondents were asked about knowledge, concerns of potential hazards, purchasing and labeling of the gene recombination foods. Most respondents (98.7%) have some knowledge on the gene recombination foods. 91.3% of respondents recognized necessity of gene recombination technology. However, they also point out its potential hazards (80.9%). The groups with less knowledge showed their increased worry on the hazard in comparison with ones of having more knowledge(p<0.01). The result indicated that there was negative relationship between knowledge and worry on the gene recombination foods. The groups with more knowledge showed their increased purchasing on gene recombination foods in comparison with ones of having less knowledge(p<0.01). The result indicated that there was positive relation-ship between their purchase intent for gene recombination foods and knowledge. 68.4% of respondents showed their interest on purchasing the gene recombination foods. In this group, most of them (44.9%) has on condition that low cost (27.0%). In addition, they also have not use the foods for their children (17.9%) if they buy it. Most respondents (85.3%) want labeling on the gene recombination foods.

Various vegetables, including cucumbers, have a high probability of foodborne illness because they are usually eaten raw. In this study, we analyzed the 16S rRNA gene sequences of the cucumber (Cucumis sativus L.) microbiota. The diversity indices of cucumber cultivated in May were higher than in cucumber cultivated in November. At the phylum level, Proteobacteria, Firmicutes, and Actinobacteria were predominant. The classes generally comprised Gammaproteobacteria, Bacilli, Alphaproteobacteria, and Actinobacteria. At the genus level, the proportions of Aureimonas, Escherichia, and Microbacterium in samples from May were relatively high, whereas Enterococcus, Pseudomonas, and Rhizobium accounted for a higher proportion in samples from November. Moreover, it is noteworthy that potential pathogenic genera such as Acinetobacter, Aerococcus, Aureimonas, Enterobacter, Enterococcus, Escherichia, Pantoea, Pseudomonas, and Staphylococcus were detected. Although further studies on the characteristics of potential pathogens are required, our results can be used to improve the food safety of vegetables.

Health risk assessments for the abandoned asbestos mine were usually performed with activity-based sampling (ABS) method, which was not a effective tool for indexing health risk on an exact small area of mine. A newly proposed potential index of health risk (PIHR) was applied with proper spatial determination of geographical information system (GIS) to assess quantitatively health risks. A new trial was applied to a certain abandoned mine in Boryong as follows: A high grade area of PIHR was estimated 7.8% of the whole area of the mine (about 27.3 ha). Based on US EPA IRIS (integrated risk information system) model considering lifetime excess cancer risk (LECR), the health risk assessment indicated that the high grade area increased from 3.0 ha through 12.9 ha to 19.5 ha with an increase of asbestos contents in soil from 0.36% (1E-04 level) through 0.1% (3E-05 level) to 0.04% (1E-05 level). These results can be effectively applied to determine reclamation area of the abandoned asbestos mine.

In this paper, an investigation on internet safety of 244 national or public elementary schools' web sites was performed with two points of view : inappropriate material posting and personal information exposure. The investigation results showed that obscene materials and commercial advertisements were uploaded into the bulletin board(67.2%) and students' personal information such as photograph, address, telephone number were exposed(87.3%). Most of the inappropriate materials were posted by auto-register programs. This problem was occurred due to reckless bulletin board opening and inappropriate management. On the contrary, personal information was exposed by teachers and students. They didn't not care about their personal information. It shows the fact that they have not recognized the danger of personal information exposure. Therefore managing real-name membership and enforcing permission to bulletin board were required to construct and use a safe school web site. Teachers have to understand not only negative effects appeared in a school web site but also latent dangerous factors.

The current traffic regulations in Korea stipulate that traffic should keep to the right according to the Road Traffic Act; thus, customarily, the 'seat-on-the-left' system has been maintained. However, an increased number of 'seat-on-the-right' vehicles are being imported via a variety of routes from foreign countries, especially from Japan. According to the data from July 2004, 1,343 cargo vehicles and 593 passenger vehicles (for diplomats, etc.) were currently being driven on domestic road. As these 'seat-on-the-right' vehicles are not compatible with the domestic transportation system of driving on the right side of the road, there is a high risk of accidents. Experiments show that such system-driver mismatch causes longer operation time for directional signals, higher error frequency in yielding due to additional mental adjustments for 'seat-on-the-right' vehicle drivers. These are, therefore, influential factors which can lead to possible accidents. Furthermore, when the experiments test the visual range during overtaking maneuvers, the visual range of the drivers in the 'seat-on-the-left' vehicle was 2.95 meters as opposed to 1.7 meters for the drivers in the 'seat-on-the-right' vehicle. (In the experiment, the drivers were instructed to look at the paper cup 10 meters away from the back of drivers' seat.) The results demonstrate that it is necessary to have additional safety measures be implemented for the 'seat-on-the-right' vehicles.

This study is to investigate the perception of domestic appraisers about the possibility of using artificial intelligence (AI) and related risks from the use of AI in the appraisal industry. We conducted a mobile survey of evaluators from February 10 to 18, 2022. We collected survey data from 193 respondents. Frequency analysis and multiple response analysis were performed for basic analysis. When AI is used in the appraisal industry, factor analysis was used to analyze various types of risks. Although appraisers have a positive perception of AI introduction in the appraisal industry, they considered collateral, consulting, and taxation, mainly in areas where AI is likely to be used and replaced, mainly negative effects related to job losses and job replacement. They were more aware of the alternative risks caused by AI in the field of human labor. I was very aware of responsibilities, privacy and security, and the risk of technical errors. However, fairness, transparency, and reliability risks were generally perceived as low risk issues. Existing studies have mainly studied analysis methods that apply AI to mass evaluation models, but this study focused on the use and risk of AI. Understanding industry experts' perceptions of AI utilization will help minimize potential risks when AI is introduced on a large scale.

Although Korea's coastal areas increasingly experience marine accident due to frequent ship encounters, increased vessel traffic and large vessel, there is a no specific model to evaluate the navigating vessel's risk for the given situation. The maritime transport environmental assessment is necessary due to the amended marine traffic law. However, marine safety diagnosis is now evaluated by foreign models. In this paper, therefore, we suggest a domestic model catering to and reflecting the characteristics of Korea's costal areas as well as those of vessel navigator's risk. We can evaluate subjective risks using this model, and can establish the model output as maritime risk exposure assessment system. We have performed analyses of variance and multiple comparison to identify the factor affecting subjective risks. As a result, measurable subjective risks of maritime traffic accident based on our suggested model can be expressed using the maritime risk exposure assessment system with geographic information system.

In this paper, we examined the causes of privacy concerns and related factors in social log-in services. On the basis of the 'principal-agent theory,' we established factors such as perceived information asymmetry and fear of seller opportunism affecting information privacy concern of social log-in services users. In addition, we analyzed the relationship between the information privacy concern and intention to use on the basis of the 'privacy calculus theory'. The results of the study showed that (1) fear of seller opportunism had the significant effect on information privacy concerns, (2) information privacy concerns had the significant effect on perceived risk, (3) in accordance with the privacy calculus theory, perceived risk had the negative effect on intention to use, while perceived benefit had the positive effect on intention to use. The findings of the study are expected to help to improve the social log-in service firms' understanding for customers' information privacy protection behaviors.
