This study was conducted to evaluate the utilization of animal by-product mixture (ABPM) as a dietary animal protein source of fish meal replacer, and to determine the effect of dietary chromic oxide in growing rainbow trout, Oncorhyncbus mykiss. ABPM is a mixture of five animal by-products such as meat and bone meal (MBM), feather meal (FM), squid liver powder (SLP), poultry by-product (PBP) and blood meal (BM) at a specific weight based ratio. Diet 1 and 2 were formulated on a isonitrogenous and a isocaloric basis of 46.5% crude protein and 16.7 KJ/g diet; diet 1(WFM 100), 100% of the animal protein source came from white fish meal; diet 2 (ABPM 40), 60% WFM+40% ABPM as the animal protein source; diet 3 (-Cr), commercial diet without chromic oxide; diet 4 (+Cr), commercial diet with chromic oxide. After eight weeks of feeding trials, fish fed diet 2 had a significantly lower body weight gain (WG) and feed efficiency (FE) than that of fish fed the other diets (P<0.05). When comparing diet 3 with diet 4, no significant differences were found in WG and FE (P>0.05). There were no significant differences on condition factor, hematocrit level, serum phosphorus, bone phosphorus, whole body phosphorus, and bone ash among fish from all four diet groups. Fish fed diet 4 had a significantly higher whole body lipid than that of fish fed the other diets (P<0.05). These results indicated that ABPM could be used less than 40% in growing rainbow trout with a sufficient period of acclimation. In addition, the 0.5% of chromic oxide can be used to determine the apparent digestibility of the nutrients in the feed without any adverse effects on growth and body composition.

This study evaluated the possible utilization and the replacing range of animal by-product mixture (ABPM) as a dietary fish meal replacer in Brewing common carp (Cyprinus carpio). ABPM is a mixture of loather meal meat and bene meal, blood meal and squid liver powder at a specific weight based ratio. Five different diets were formulated on isonitrogenous and isocaloric basis of 40% crude protein and 15.3 KJ/g diet in which white fish meal (WFM) protein was substituted with the ABPM protein as follows: diet 1, 100% WFM (0% ABPM, control): diet 2. 75% WFM+25% ABPM (25% ABPM); diet 3, 50% WFM+50% ABPM (50% ABPM); diet 4,25% WFM+75% ABPM (75% ABPM); diet 5,0% WFM+100% ABPM (100% ABPM). As the dietary protein sources, each diet contained 34.7% of animal protein supplied by white fish meal and/or ABPM and 65.3% of plant protein. After one week of conditioning period, fish averaging 10g were randomly assigned to each diet 1 (control) and 3 were significantly higher than those of fish fed diet 2, 4 and 5 during the first 4 weeks (P<0.05), while there were no significant differences among all diet groups during the third 4 weeks (P>0.05). Feed conversion ratio of fish fed diet 1 was significantly higher than those fad diet 2, 3, 4 arid 5 during the second 4 weeks (P<0.05), while there were no significant differences among all diet groups during the first and the third 4 weeks (P<0.05), There were no significant differences in proximate analysis among fish fed the experimental diets either far the second 4 weeks or the third 4 weeks (P>0.05). These results indicated that ABPM could be used as a fish meal replacer up to 100% in growing common carp.

Purpose: This study primarily aimed to investigate on the perception of occupational suitability for speakers who stutter and the associated factors. Methods: 30 occupational counsellors participated in this study and asked to hear one of three audio recordings (i.e., fluent version, mildly-stuttered version, and severely-stuttered version) of a male speaker who stuttered. The participants were then asked to rate the speaker’s communicative functionings, personal attributes, and suitability for 31 occupations, along with perceptions of the occupations’ speaking demands and educational requirements. Results: Results show that speakers who stuttered (i.e., mildly-stuttered and severely-stuttered version) received lower suitability ratings for high speaking demand occupations than for low speaking demand occupations. Conclusion: From these findings it can be argued that adults who stutter may face occupational stereotyping and/or role entrapment in work settings.

연구목적: 본 연구의 목적은 피치마켓이 만드는 “느린학습자를 위한 적정도서” 가 느린학습자와 의미있는 타자들에게 어떤 변화를 가져오는가를 알아봄으로써 피치마켓 사업의 성과를 알아보고자 함이다. 연구방법: 느린학습자, 교사, 부모로 구성된 연구참여자 13명과 심층 인터뷰 13회를 실시하고, 멘토 5명으로 구성된 포커스 그룹을 구성하여 인터뷰를 실시하였다. 또한 6회에 걸쳐 독서 활동 현장을 찾아 참여관찰을 시행하였다. 적정도서를 접한 느린학습자들의 읽기 수준의 차이를 알아보기 위해 TOPIC 척도를 활용하여 사전사후검사를 실시하여 자료를 수집하였다. 연구결과: 느린학습자들은 피치마켓이 제공하는 적정도서를 통해 자신이 텍스트를 장악하는 경험을 하게되었다. 느린학습자들을 관찰한 부모와 교사들은 이해할 수 있는 텍스트를 접한 느린학습자들이 그 텍스트를 나와 연결시키면서 자신의 사고를 하기 시작했다고 말했다. 피치마켓에서는 적정도서와 더불어 느린학습자들이 함께 읽는 장을 제공하여, 개인적인 독서 행위를 사회적인 것으로 확장시켰다. 적정도서와 독서 활동을 통해 느린 학습자들이 경험한 바는 느린학습자들의 일상으로 전이되었다. 책을 스스로 선택해서 읽거나 책을 가지고 다니는 느린학습자들도 생겨났다. TV에서 뉴스도 보고, 설명도 하고, 질문도 하는 일상이 전개되었다. 느린학습자를 교육하는 위치에서는 교사와 멘토들은 새로운 접근방법을 얻게 되었다. 교사들은 피치마켓의 적정도서가 좋은 교재를 만드는 조력자가 되었다고 말했다. 결론: 본 연구는 느린학습자를 관찰한 교사, 부모, 멘토를 조사함으로써 적정도서와 독서활동을 경험한 느린학습자들의 구체적인 변화를 확인하고 특수교사와 부모에게 느린학습자를 위한 적정도서의 필요성을 촉구하였다.

This study was mainly aimed to investigate on the perceptions of occupational suitability for speakers who stutter and the associated factors. 90 college students who do not stutter participated in this study and asked to hear one of three audio recordings(i.e., fluent version, mildly-stuttered version, and severely-stuttered version) of a male speaker who stuttered. Then, the participants were asked to rate the speaker’s communicative functioning, personal attributes, and suitability for 31 occupations, along with perceptions of the occupations’ speaking demands and educational requirements. Results show that speakers who stuttered (i.e., mildly-stuttered and severely-stuttered version) received lower suitability ratings for high speaking demand occupations than for low speaking demand occupations. In addition, it has been shown that perceived speaking demand strongly affected occupational suitability ratings at both levels of stuttering severity. However, it has been shown that occupational suitability ratings were not associated with ratings of the speaker’s personal attributes and perceived educational requirements. From these findings it can be argued that adults who stutter may face occupational stereotyping and/or role entrapment in work settings.
