We found that Micrococcus luteus peptidoglycan (PGN) was best at inducing lugworm AMPs. After stimulating lugworms with PGN from M. luteus, AMP-induced lugworm powder was added to feed that was fed to whiteleg shrimp. The effects of whiteleg shrimp on growth performance, serological components, and bacterial infection were investigated. We fed whiteleg shrimp AMP-induced lugworm powder at 0% (control), 0.05%, 0.1%, 0.5% and 1% ratios for 8 weeks. The specific growth rates (SGR) were significantly increased in all tested groups compared with the control. In addition, it was confirmed that the feed conversion ratio (FCR) and protein efficiency ratio (PER) were improved in a concentration-dependent manner. In the 2nd, 4th, 6th, and 8th weeks after the start of feeding, total cholesterol (TCHO), glucose (GLU), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) levels were tested, and no significant changes were detected in any of the results. The lysozyme level showed a significant increase in the 1% experimental group, and the cortisol level did not significantly change in any of the experimental groups. After 8 weeks of the feeding trial, whiteleg shrimp were infected with Vibrio harveyi and observed for 20 days. The 0.05% test group showed the lowest mortality rate, and the 1% test group showed significantly higher mortality than the control group on the 5th day.","PeriodicalId":148968,"journal":{"name":"JOURNAL OF FISHRIES AND MARINE SCIENCES EDUCATION","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127967250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the color value, lightness had the highest value for MFT-0, but redness and yellowness had the highest value for MFT-144. The amount of free amino acid gradually increased with the increase of fermentation time, in which the main amino acids were glutamic acid, glycine and alanine in all samples. The color, odor, taste and overall acceptance score decreased after 24 hours of fermentation, and MFT-24 had the highest score of texture. Therefore, fermentation at 3~4 for °C 24 hours was suggested to be the optimum manufacturing condition.","PeriodicalId":148968,"journal":{"name":"JOURNAL OF FISHRIES AND MARINE SCIENCES EDUCATION","volume":"209 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122665794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result of AHP analysis of the support system for seafood processing companies, support for facilities and equipment(0.358) is the most important for the support system for seafood processing companies, followed by technical support(R&D)(0.315), marketing support(0.257). and management support(0.070). In the results of AHP analysis by each survey group, there is a difference in the perception of importance in support policy for seafood processing companies. Seafood processing companies show high importance in facilities and equipment support(0.589) but low importance in technology(R&D) support(0.078).

This study, therefore, adopted club activities rather than classes as a creative experiential activity that allows for free exploration with less burden of learning. Using club activities, this study aimed to examine how the students’ how to increase their interest in mathematics, and how to improve their negative perception of mathematics. It was also explored whether club activities can help students enhance their learning ability by changing the perception of mathematics. To this end, students were offered an opportunity to engage, various types of activity-based classes and cooperative learning activities such as watching movies, special lectures, overnight camping, math festival, and a visit to the National Institute for Mathematical Sciences. As a result, students’ interest in mathematics has improved and their perception of mathematics has changed that mathematics is not intended to produce a result, but a process of thinking. By seeing and experiencing mathematics is being used in diverse areas, students have also realized how useful mathematics is.

In order to accomplish this purpose, the data for the research was gathered through the interviews with seventeen parents. These data were analyzed using qualitative data analysis. The results of this study were as follows: First, there is little contact between the parents of underachieving high-school students and their school teachers. Second, there is a disjunction between the parents’ expectation for their school teachers and their performance in career guidance, teaching, and life guidance. Third, school organization (overcrowded class, departmental system, teachers’ overloaded work), school culture(cultural of entrance, parents’ reliance on private education, denial of the school parents as subject of education), and educational policies(complexity and frequent change of the system of college entrance exam, Personal Information Act, lack of school autonomy) had an undue effect on the parents of underachieving high-school students’ trust in their school teachers. In conclusion, parents need to have a great deal of opportunity to meet their school teachers. High school teachers need to have an expertise in career guidance, teaching, and life guidance. Some innovations in school organization, school culture, and educational policies are required for the parents of underachieving high-school students to have a lot of trust in their school teachers.","PeriodicalId":148968,"journal":{"name":"JOURNAL OF FISHRIES AND MARINE SCIENCES EDUCATION","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129775322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
