This study was conducted to evaluate dietary hydrolyzed pig bristle meal (PBM) for juvenile olive flounder Paralichthys olivaceus. In Experiment 1 (EXP-1), six experimental diets were prepared to contain 0, 3, 6, 9, 12 and 15% PBM (designated Con, PBM3, PBM6, PBM9, PBM12 and PBM15, respectively). Triplicate groups of olive flounder (initial body weight, 8.69 g) were fed the diets to apparent satiation for 8 weeks during the optimal water temperature season (20.5±2.12℃). All PBM supplemented groups except for PBM3 showed significantly lower growth performance and feed utilization compared to the control group. The protein digestibility of PBM3, PBM6, and PBM9 diets did not significantly differ from that of the control diet. In Experiment 2, 1% mono-calcium phosphate was added into the experimental diets used in Exp-1. Triplicate groups of olive flounder (10.6 g) were fed the diets to apparent satiation for 8 weeks during the low water temperature season (12.5±1.12℃). The growth performances and feed utilization of fish fed all diets except for PBM15 diet did not significantly differ from those of the control diet. This study indicates that hydrolyzed PBM can replace fish meal by up to 12% with limiting amino acids and mono-calcium phosphate in diets for juvenile olive flounder.

본 연구에서는 테크놀로지와 디자인 융합교육 프로그램을 개발하고 이에 대한 효과성을 검증하였다. 이를 위한 연구방법은 문헌적 접근과 실증적 접근, 학생들의 적용사례 결과를 융합하여 분석하였다. 문헌분석은 학술정보서비스(RISS)’와 ‘한국교육학술정보원(KERIS)’에서 관련 키워드를 교차검색 후 도출된 관련 보고서 및 연구, 관련 사이트 내 정보를 통해 국내외 디자인과 테크놀로지의 교육과정 현황을 분석하였다. 또한 실증사례로 연구자가 개발한 ‘디자인과 테크놀로지의 융합’ 프로그램을 서울시 소재 S여자대학 재학생 55명에게 총 19회 38시간 적용하고 그 효과성을 확인하였다. 분석도구는 총 15문항으로서 리커트(Likert) 척도로 구성된 14문항과 서술 형식의 오픈 1문항이다. 분석도구 개발은 디자인적 사고방식과 새로운 테크놀로지와의 융합에 관한 국내 · 외 단행본과 선행연구논문, 관련 학위 논문 등을 분석하여 본 연구에 적합한 부분을 도출하여 수정 · 보완 후 문항을 재구성 하였다. 그 결과, 학생들은 테크놀로지와 디자인의 융합교육에서 모험심, 융합능력, 신기술습득에 대한 가치영역을 높게 평가하였다. 이는 적용된 융합수업이 학생들에게 새롭고 신선한 자극을 줄 수 있었던 것으로 해석된다. 반면 분석력, 시각적 문해력, 공유 부분을 다소 낮게 평가 하였다. 이러한 결과는 COVID-19 이후에 진행된 온라인 수업에 따른 영향으로 분석된다. 결과적으로 본 연구는 현대사회의 문제해결의 핵심 키워드인 ‘융합’을 테크놀로지와 디자인의 융합을 통해 바라 볼 수 있는 기회를 마련하여 디자인교육의 변화에 대한 기초자료로 활용될 수 있기를 기대한다. In this study, the technology and design-convergence education program was developed and its effectiveness was validated. To this end, the research method is analyzed by fusion of the results of the literature and empirical approach, and the results of students’ application cases. The literature analysis analysed the current status of the curriculum of domestic and foreign design and technology through related reports, research, and information on related sites derived after cross-searching related keywords from ‘Academic Information Service (RISS)’ and ‘Korea Education and Research Information Service (KERIS)’. In addition, as an empirical case, the “Convergence of Design and Technology” program developed by researchers was applied to 55 students at S Women’s University in Seoul for a total of 19 times for 38 hours to confirm its effectiveness. The analytical tool consist a total of 15 questions, 14 questions composed of the Likert scale and one open question in a narrative form. The development of analysis tools analyzed domestic and foreign books, previous studies, and related thesis on the convergence of design thinking and new technology, derived suitable parts for this study, and reorganized the items after revision and supplementation. As a result, students highly appreciated the areas of value for adventure, convergence capability, and acquisition of new technology in the convergence education of technology and design. The applied convergence class is able to give new and fresh impulses to students. On the other hand, analytical skills, visual literacy, and shared parts were slightly underestimated. These results are analyzed due to the effect of online classes conducted after COVID-19. As a result, this study is expected to provide an opportunity to see ‘Convergence’, the keyword for solving problems in modern society, through the convergence of technology and design, and use it as a basic data on changes in design education.

This study examined the effects of dietary supplementation with citrus by-product (CBP) on the growth, feed utilization, innate immunity, and histology of the gills and intestine of juvenile olive flounder Paralichthys olivaceus during low water temperature season. A vitamin C-free basal diet was regarded as a control and five other diets were formulated that contained 30 and 300 mg of L-ascorbyl-2-polyphosphate (LAPP) or CBP as vitamin C equivalents/ kg diet, or the antibiotic oxytetracycline (OTC) (designated as control, LAPP30, LAPP300, CBP30, CBP300, and OTC, respectively). Olive flounder (initial body weight 44.6±0.32 g) were fed the six experimental diets to apparent satiation for 9 weeks. Growth and feed utilization were significantly higher in CBP30 than in the control and LAPP groups. The lysozyme activity was significantly higher in CBP30 than in LAPP300. Enterocyte height was significantly higher in CBP30 than in the control. The number of goblet cells was increased significantly with LAPP30, LAPP300, and CBP30. These results demonstrate that CBP can reduce or replace vitamin C and antibiotic in the diet of olive flounder during the low-water-temperature season. The optimal CBP supplementation level seems to be approximately 1%, which is equivalent to 30 ppm vitamin C/kg in the fish diet.

Social media and my avatar:Can the avatar influence SNS users’ attitudes toward health message ?

급증하는 소셜 미디어의 대중화의 기류를 타고 많은 의사들이나 의료 서비스 제공자들이 그들의 젊은 환자들과 소통하기 위해 소셜 미디어에 참여하고 있다. 그럼에도 불구하고, 여전히 더 많은 사람들, 특히 SNS 이용자들에게 접근하기에는 좀 더 효과적인 전략이 필요한듯 하다. 이에 본 연구는 효과적인 전략을 제시하기에 앞서, 우선 어떻게 각각의 SNS(예를 들면, 페이스북, 유투브, 또는 트위터)가 건강 정보의 소스로 사용되어 왔는지 그 실태를 조사하여 기록하고, 이를 토대로 젊은 SNS 이용자들을 타켓으로 하는 효과적인 건강 커뮤니케이션에 유용한 여러가지 제안사항과 혁신적인 툴이나 적용가능한 전략들 몇가지를 소개하고자 한다. 그리고 마지막으로, 그 효과적인 툴의 하나로서 본 연구는 아바타 즉, 자신을 온라인상에서 대신할 수 있는 가상 캐릭터를 소개하고, 이 아바타가 과연 SNS 이용자들의 건강 메세지를 대하는 태도에 영향을 줄 수 있는지를 밝히고자 한다. 이를 위해, 본 연구는 자신의 아바타를 생성하고 꾸밀수 있는 서비스를 제공하는 한국의 SNS중 하나인 Cyworld를 이용하였고, 총 69명이 실험에 참여하였다. 결과는 실험참가자 자신의 실제 모습과 비슷하게 아바타를 꾸민 참가자들은(participants with actual self-resembling avatars), 자신의 이상적인 모습과 비슷하게 아바타를 꾸민 참가자들(participants with ideal self-resembling avatars)이나, 아바타가 없었던 참가자들(participants with no avatars)보다 싸이트상에 보여진 피부암 광고에 대해 좀더 높은 수준의 근심도와 긍정적 태도를 나타내었다. 본 연구는 여러가지 연구조작물의 디자인적 한계점들(예를 들면, 아바타가 만화같은 형태라든가, 아바타를 꾸미는 옵션들이 매우 제한적이었다는 등)이 있었음에도 불구하고, 젊은 SNS 이용자들을 타겟으로 하는 효과적인 건강 캠페인을 디자인하는데 실질적인 방향성을 제공했다는데(예를 들면, 다양한 아바타 타입에 따른 다양한 전략의 필요성 등) 그 의미를 찾을 수 있겠다. With the rapid increase in the popularity of social media, a number of physicians and health providers have joined social media outlets to communicate with their young adult patients. Nevertheless, it still needs more effective strategies to reach out more people, especially SNS users. The current study briefly documents how each social networking site (e.g., Facebook, Youtube, or Twitter) has been used for a health information source, and then suggests several tips and innovative applications, which might be useful for making the effective health communication targeting young SNS users. Finally, as one of innovative tools, this study introduces the use of avatar (i.e., virtual character to represent the user) for engaging SNS users in health information and empirically tests its’ effect and the role of avatar use on SNS users’ attitudes toward the information. Leveraging a Korean social networking site, Cyworld, which currently offers users to create avatars, this study (N = 69) found that participants with actual self-resembling avatars (i.e., avatars that look like participants’ current appearance) reported a higher level of anxiety and more positive attitudes toward the interactive skin cancer ad on the website than participants with ideal-self-resembling avatars (i.e., avatars that look like participants’ ideal images) and participants with no avatars. In spite of several limitations such as employing cartoon-like avatars or limited options of avatar customization, it has many practical implications (e.g., different message strategies for different avatar types) for designing effective health campaigns, particularly targeting SNS users.

저수온기(13-15℃) 치어기 참돔(Pagrus major) 사료 내 비타민 C 대체제로써의 감귤착즙박 및 발효감귤착즙박의 이용 가능성

이초롱 ( Chorong Lee ),김유정 ( Youjeong Kim ),이경준 ( Kyeong Jun Lee ) 한국수산과학회 2015 한국수산과학회지 Vol.48 No.4

This study compared the effects of dietary supplementation of citrus by-product (CBP) and CBP fermented with Bacillus subtilis (F-CBP) on growth performance, feed utilization, intestinal histology and innate immunity of red seabream Pagrus major with three commercial immune-boosting products. The six experimental diets were supplemented with L-ascorbyl-2-polyphosphate (LAPP; the control diet), CBP or F-CBP at a concentration of 100 mg vitamin C equivalent/kg diet or one of three commercial immune boosters. The Experimental diets were fed to triplicate groups of 17 fish (initial body weight, 116 g) for 8 weeks. The water temperature during the feeding trial was maintained at 13-15℃. Growth and feed utilization did not differ significantly among the six dietary treatments, nor did the phagocytic activity, superoxide dismutase or total immunoglobulin concentrations. However, myeloperoxidase activity was significantly higher in the CBP groups. For the intestinal histology, the intestine diameter, villi and enterocyte heights and number of goblet cells did not differ significantly among groups. Therefore, CBP or F-CBP can be used as a valuable eco-friendly byproduct in diets for fishes including red seabream to maintain their normal growth and health.
