말쥐치의 年間 探肉率과 化學成分을 測定 分析한 結果는 다음과 같다. 1. 採肉率은 3∼6月에 낮고, 7∼12月에 높다. 2. 水分은 3∼6月에 81.4∼82.0%로 높고, 7∼12月에 77.5∼80.1%로 낮다. 1∼2月에는 79.4∼81.4% 였다. 3. 蛋白質은 3∼6月에 含有量이 15.4∼15.7%로 낮고 7∼12月에 71.0∼19.9%로 높다. 1∼2月에는 16.1∼17.0%였다. 4. 脂質의 含有量은 3∼6月에 0.31∼0.41%로 낮고, 7∼1月에는 0.46∼0.48%로 높다. 2月에는 0.43%였다. 5. 炭水化物의 含有量은 3∼7月에 0.3∼0.4%로 낮고 8∼1月에 0.5∼0.7%로 높다. 2月에는 0.3%였다. 探肉率과 化學成分 測定結果는 7∼12月에 採肉率이 높고 蛋白質의 含有量도 많다. The ratio of the eatable flesh taken from the filefish and its chemical components were investigated from March 1980 to February 1981 and the results are as follows: 1. The ratio of the eatable flesh taken from the fish was low during March to June and high during July to December. 2. The moisture content was 81.4-82.0% during March to June, 77.5-80.1% during July to December and 79.4-81.4% duriug January to February. 3. The protein content was 15.4-15.7% during March to June, 17.0-19.9% during July to December and 16.1-17.0% during January to February. 4. The Lipid content was 0.31-0.41% during March to January, 0.46-0.84% during July to January and 0.43% during February. 5. The carbohydrate content was 0.3-0.4% during March to July, 0.5-0.7% during August to January and 0.3% during February. In conclusion, the ratios of the eatable flesh taken from the filefish and its protein content were highest durng July to December in one year.

Nowadays, large amount of waste pottery and porcelain annually are produced. It is needed that they are used as recycled materials in order to prevent environmental pollution and gain economic profits. Therefore, the purpose of this study is to present the method of utilizing the recycled aggregates that are obtained from waste pottery and porcelain as the concrete aggregate. The qualities of the recycled aggregate were compared with those of the crushed aggregate through measuring their physical properties. The test results showed that the replacement of crushed aggregate by recycled aggregate at the levels $10\%,\;20\%$, and $30\%$ had little effect on the compressive strength of the concretes, but higher levels of replacement reduced the compressive strength. Increment of the replacement of recycled aggregate caused increase in absorption ratio. As a conclusion, norman strength recycled aggregate concretes can be produced using less than $30\%$ of recycled aggregate. 현재 국내에서 많은 양의 도자기 폐기물이 발생하고 있으며, 이들 폐기물은 경제적 이득과 환경 보전의 차원에서 재활용하는 방안이 모색되어져야 한다. 따라서, 본 연구에서는 도자기 폐기물을 콘크리트용 골재로 이용하여 폐도자기의 재활용성을 검증하고자 하였다. 폐도자기 재활용 골재(recycled aggregate)의 품질을 부순 골재(crushed aggregate)와 비교 분석하였으며, 부순 골재 단독 콘크리트와 재활용 골재가 비례대로 치환된 콘크리트의 물리적 특성을 비교 분석하였다. 실험 결과 재활용 폐도자기의 비율이 $10\%,\;20\%$, 그리고 $30\%$까지는 압축강도에 작은 영향을 미쳤지만, 재활용 폐도자기의 비율이 $30\%$ 이상 증가할수록 압축강도는 급격히 감소하였으며, 홉수율은 증가하였다. 실험 결과에 따르면, 일정한 압축강도를 지니는 폐도자기 재활용 콘크리트의 제조를 위해서 대체 가능한 재활용 골재의 최대 함량은 $30\%$임을 확인 할 수 있었다.
