The expriment was carried out to clarify the fertilizer efficiency of a garbage- based compost in cultivation of leaf vegitables. 1. Only application of 8 tons per 10 of the compost did not have any growth injury to ‘ Osaka-shirona" (a cultivar of Brassica pekiηeηsis L.) in a pot experiment 2. In four continuous cropping with application of 3 tons per 10 a of the compost before every seeding, ‘ Osaka -shirona’ grew satisfactorily. 3. Osaka-shirona, spinich and garland chrysanthemum were cultivated under a plastic house applied with 2 tons per a of each of the garbage- based compost and cattle manure, delayed release fertilizer and bark compost on the market. There was no difference of the vegetable yields among the applied field , as well as of the contents of P-carotene, vitaminC, Ca and Fe. 1. 잔반퇴비의 비효특성을 봇뜨시험에 의하여 비효의 지속기간 및 사용한계량을 밝혔으며 실용규모 비닐하우스 내에서의, 논을 밭으로 만든 토양을 이용하여 잔반퇴비와 다른 유기질비료를 시용하여 재배한 연약야채의 수량 및 영양성분특성을 조사하여 잔반퇴비의 연약야채재배에 미치는 효과적 이용법에 대하여 검토하였다. 2. 화학비료를 시용하지 않을 경우는 10a 당 8 ton 의 시용에서도 토양 EC 및 pH 가 발아장애나 그후의 생육저해를 일으키는 위험성은 인정되지 않았다. 3. 大版시로나 (갓)을 4모작 재배하는 사이에 10a당 5tX4 회 합계 20 ton 의 잔반퇴비를 시용하였지만 적지의 EC, pH 가 발아장애 또는 생육저해를 일으키는 위험성은 볼 수 없었다. 4. 연약야채는 잔반퇴비 10a당 2 ton 정도 시용하였을 때 건조우분 바크퇴비, 다른 유기질비료와 비교하여 수량, 외관의 품질 및 내용성분에 대해서도 같은 정도 또는 그 이상의 결과를 얻을 수 있었다. 5. 잔반퇴비는 분해가 빠르고 유실이 많다고 생각된다. 비효기간이 짧기 때문에 차작시 堆服가 필요하고 작물재배시마다, 2-3 ton 정도의 연속시용이 수량증가에 대해 효과적이었다.

Feeding trials were conducted with Euglena strains grown under different media. The effect of supplementation of Euglena on the laying performance, egg quality and fatty acid composition of egg yolk was studied. In experiment I, two hundred eighty 32-wk-old ISA Brown layers were randomly assigned to seven dietary treatments for 4 wks. Each treatment consisted of 4 replications with 10 birds each housed in two birds cages. Control diet was formulated to have $17\%$ CP and 2,750 kcal ME/kg. Euglena gracilis Z. (EG) was added to control diet at the level of 0.25, 0.5, $1.0\%$ and Euglena gracilis Z. bleached and DHA enriched (EGBD; a strain mutated by streptomycin and cultivated in DHA enriched medium) at the level of 0.5, 1.0, $2.0\%$ in the diet. In experiment 2, three hundred 84-wk-old ISA brown layers were randomly assigned to five dietary treatments: T1; Control, T2; T1 + EGBD $0.5\%$, T3; T1 + Euglena gracilis Z. DHA enriched (EGD; cultivated in DHA enriched medium) $0.5\%$, T4; T1 + EGD $1.0\%$, T5; T1 + EGD $2.0\%$. Each treatment had 5 replication of 12 birds each housed in two birds cages. In experiments 1 and 2, Euglena suppplementation did not significantly affect egg production but increased egg weight and feed intake. In experiment 1, EG was more effective in increasing egg yolk color score than EGBD. Egg yolk color of EG $1\%$ treatment showed the highest score. EGBD supplementation increased DHA concentration of egg yolk. EGBD $2\%$ treatment showed the highest DHA and the lowest palmitic and stearic acids concentration in the egg yolk. In experiment 2, EGBD $0.5\%$ treatment showed highest DHA level in egg yolk (P<0.05). It was conducted that EGBD is a single cell protein source rich in DHA, that can be used to produce DHA enriched eggs.

A feeding trial was conducted with Euglena strains grown under different media. The effect of supplementation of Euglena on the performance, nutrient availability and fatty acid composition of breast muscle was studied. In experiment I, two hundred ten hatched broiler chicks (Ross) were assigned to seven dietary treatments for 5 weeks. Each treatment consisted of 3 replications with 10 birds each. Control diet was formulated to have $22\%$ CP and 3,150 kcal ME/kg for starter diet, $19\%$ CP and 3,200 kcal ME/kg for finisher diet. Euglena gracilis Z. (EG) was added to control diet at the plevel of 0.25, 0.5, $1.0\%$ and Euglena gracilis Z. bleached and DHA enriched (EGBD; a strain mutated by streptomycin and cultivated in DHA enriched medium) at the level of 0.5, 1.0, $2.0\%$ in the diet. In experiment 2, two hundred fifty hatched broiler chicks (Ross) were assigned to five dietary treatments: T1; Control, T2; T1 + Euglena gracilis Z. DHA enriched (EGD; cultivated in DHA enriched medium) $0.5\%$, T3; T1 + EGD $1.0\%$, T4; T1 + EGBD $0.5\%$, T5; T1 + EGBD $1.0\%$. The weight gain and feed consumption were measured weekly. Fatty acid composition of breast muscle was determined. In experiments I and 2, Euglena supplementation had no significant effects on weight gain, feed intake and feed conversion ratio. In experiment 1, EGBD treatments significantly increased DHA concentration but decreased concentration of linoleic acid and arachidonic acid in breast muscle. EGBD 2% treatment showed the highest DHA concentration (14.27%) which is 3.9 times of that of the control ($3.66\%$). In experiment 2, $1.0\%$ EGBD treatment showed highest EPA, lignoceric acid and DHA level in breast muscle (P<0.05). Also, EGD treatments significantly increased DHA and EPA concentration. It was concluded that EGBD and EGD can be supplemented to broiler diet to produce DHA enriched broiler meat.

본 연구에서는 다문화 청소년의 신체만족도가 우울에 미치는 영향을 확인하고, 두 변인간의 관계에서 사회적 위축이 매개효과를 나타내는지 분석하였다. 이를 위해 한국아동청소년정책연구원에서 실시한 다문화청소년패널조사(MCAP) 6차(2016년) 자료의 1,228명을 살펴보았다. 빈도분석 및 기술통계, 상관분석, 위계적 회귀분석을 실시하였고, 매개효과 검증을 위하여 부트스트래핑(bootstrapping)을 실시하였다. 분석결과, 다문화 청소년의 신체만족도가 우울에 부적인 영향을 미치는 것으로 나타났으며, 다문화 청소년의 신체만족도가 우울에 영향을 미치는데 있어서 사회적 위축의 부분 매개효과가 검증되었다. 이러한 연구결과를 바탕으로 다문화 청소년의 우울을 감소시키기 위해 신체만족도를 증가시키고, 사회적 위축을 감소시키는 방안에 대해 제시하였다. The purpose of this study was to examine the mediating effect of social withdrawal in the relationship between body-cathexis and depression among adolescent of the multi-cultural family. The participants were 1,228 adolescent of the multi-cultural family, with data taken from the 6th year(2016) Multi-cultural Children and Adolescents Panel Study(MCAPS). A hierarchical regression analysis was conducted to examine the mediating effect of social withdrawal in the relationship between body-cathexis and depression among adolescent of the multi-cultural family. A bootstrapping was used to examine the mediating effect. The results showed that body-cathexis was found to have negative impact on the depression. Further, partial mediating effect of withdrawal was found in the relationship between body-cathexis and depression. Based on these result, suggestions and implications were provided.
