This study investigated whether there is a correlation between the occurrence of hazardous substances such as vibrio, norovirus, radioactivity, shellfish posion, hepatitis A, etc. and media reports, and whether the occurrence of hazardous substances and media reports affect the production, distribution and consumption of aquatic products. The main research results are as follows. First, it can be seen that there is a difference in the relationship between the occurrence of hazardous substances and media reports according to hazardous substances. Second, it suggests seen that the occurrence of hazardous substances and media reports can have a negative effect on the production and the prices of aquatic products. Third, it was found that the occurrence and reporting of hazardous substances had different effects on the distribution margin of aquatic products due to the complexity and rigidity of the distribution structure. Fourth, consumers feel a threat to aquatic products safety and significantly reduce consumption when hazardous substances occur. There is a possibility that concerns about one item may lead to a decrease in consumption of domestic and imported aquatic products that are not related at all to the occurrence of hazardous substances. In conclusion, aquatic products are exposed to various hazardous substances such as vibrio, norovirus, radioactivity, shellfish posion, and hepatitis A. It was found that the occurrence of hazardous substances and its media reports could cause damage to the fishery sector.

Purpose: This study aimed to identify the effects of adolescent sexual media literacy and sexual permissiveness on gender sensitivity and to provide evidences useful in developing a sex education program that would promote gender sensitivity among adolescents. Methods: Data were derived from 250 adolescents' responses to questionnaires. Collected data were analyzed using ANOVA, Pearson's correlation coefficient, and multiple regression. Results: Gender sensitivity according to gender was significantly different (t=-6.54, p=0.001). Gender sensitivity was positively correlated with sexual media literacy (r=0.36, p<0.001), and negatively correlated with sexual permissiveness (r=.22, p<.001). Sexual media literacy was negatively correlated with sexual permissiveness (r=-0.39, p<0.001). The variables affecting the participants' gender sensitivity on media literacy were gender (β=0.33, p<0.001) and sexual depiction scene (β=0.24, p<0.001). Conclusion: Gender and sexual media literacy influenced participants' gender sensitivity. Therefore, when developing a school-based sex education program, sexual media literacy should be included as a key concept; moreover, gender-specific programs need to be developed. Furthermore, teaching methods should enhance media literacy related to sexual depiction scenes and promote safe and healthy sexual permissiveness.

Sand filter is a key unit process for particle removal in water purification treatments. Its long-standing use is due to on-site customized retrofit. Proper selection of filter media is one of the retrofit approaches to improve filter performance. This study described a series of controlled laboratory column tests and examined the effects of media property on filtration and backwash. When sand media of 0.51 mm in effective size was replaced by sand of 0.60 mm, the filter run increased up to 5 times in the given bed depth. The change of media property required an increase of backwash rate by 0.05 m/min to satisfy the requirement of bed expansion, more than 20%. When the anthracite was changed with lower effective size and uniformity coefficient, correlation with sand in the filter bed could be satisfied within the permissible error between media and bulk characteristics. Besides, this selection resulted in a well-stratified configuration of media layers after bed expansion. The column study showed that the correlation of property between the dual media had a significant effect on the filter productivity and backwash interval.
