서주수 진주산업대학교 1993 論文集 Vol.32 No.-

This study was attempted to establish the basic date for rapid fermentation method of the salted fish. Bacillus sp. EY1 that was identifided as halophilic microorganism producing active protease from the conventionally fermented commercial salted fish was used as a starter. For this purpose the salted fishes were fermented for two months at room temperature with starter and without starter. Chemical composition of the products fermented with starter such as moisture, crude protein, ash, and crude lipid, and free amino acid was appeared to be almost same as or better than that of the once withot strater. The major free amino acids in salted jack mackelel, histidine, proline, leucine, and valine were dominant holding 54.7% of total free amino acids while leucine, proline, lysine, alanine and glutamine in salted cuttle fish were dominant holding 60.3% of total free amino acids and these contents of amino acids in salted fish were higher than that of the products of without starter. It is concluded that the increment of proline, leucine, lycine, valine, alanine, cystein, tyrosine and other histidine, tryptophane was concerned with the slightly bitter taste in salted fish.

西晋州 地域에 位置하여 南江으로 흘러 들어가는 羅佛川의 季節別 水質汚染度의 變化를 調査하기 위하여 1983年 4月부터 12月까지 羅佛川의 세 지점에서 氣溫, 水溫, pH, DO, BOD, COD, 硬度, n­Hexane抽出物 SS등을 分析한 結果를 要約하면 다음과 같다. 1. pH는 各 地點이 6.8∼8.4로 나타났으며, 環境保全法 生活用水 水質基準 3級水域에 해당하였다. 2. BOD는 7.9∼32.2ppm의 분포를 보였으며 下流地點이 上流地點보다 다소 높은 傾向을 보였고 降雨量이 많았던 4月, 7月, 9月의 平均 BOD 값은 11.5ppm으로 다소 낮은 傾向을 나타냈으나 環境保全法의 3級水의 基準値(10ppm)을 대부분 넘었다. 3. COD는 10.0∼43.1ppm으로 BOD와 비슷한 傾向이었다. 4. 硬度는 51∼180ppm으로 나타났으며 上流가 下流보다 전체적으로 높았다. 5. n­Haxane抽出物, SS는 各各 0∼2.7, 10∼42ppm으로 나타났고 環境保全法 下水基準을 超過하지 않았다. To investigate seasonal variation of the water pollution of the Nabul­Cheon which is flowing into Jinju Nam­river, water temperature, pH, DO, BOD, hardness, extraction matters of n­hexane and SS were analysed at three sites of that from April to December in 1983. The results were as follow; 1. The pH value of each site was 6.8∼8.4. This was the third grade(pH5.8∼8.5) of raw water quality standard of water supplies. 2. BOD were 7.9∼32.2ppm BOD value of site A was a little higher than site C. The average BOD of April, July, September which had much rain was a little lower, but these Bod were beyond the limit of the third grade(less than 10ppm) of raw water quality standard of water supplies. 3. COD were 10.0∼43.1ppm. 4. Hrdness were 51∼180ppm. Site A higher than site C. 5. Extraction matter of n­hexane, SS were 0∼2.7, 10∼42ppm. These were not beyond the times of the waste water discharging standard.

現代科學敎育의 指導方法의 中心을 이루는 것은 學生들 스스로가 學習活動에 積極的으로 參與하고 그기서 새로운 것을 創造, 管理, 發見하는 것인데 이것을 實現하기에 가장 알맞은 敎育方法이 實驗實習이며 이 實驗實習도 다음과 같은 事項에 對하여 緻密한 計劃이 實驗實習 以前에 이루어지지 않코서는 理論 中心의 講義보다 조금도 나을것이 없다. 實驗實習은 學生들에게 1. 事實 2. idea 3. 技能 4. 討論 5. 發見 또는 實驗하는 科程을 通하여 科學하는 方法을 가르쳐 주는 것이다. 이와같은 目的을 達成하기 爲하여서는 實驗授業은 實驗의 課題와 目標, 實驗의 樣式과 時間, 實 實驗, 實驗後의 指導 等의 內容으로 展開되어야 驗前의 指導, 實驗準備, 代用할 수 있는 器才, 本 할 것이다. The mainpoint of the method of guidance for mordern scientific education should be taking part in the learning activities posivirely. Then the students will find a new fact there. That is, what is creation, administration and discorery? The suitable method to carry into effect is to have experiments and practices. Befor we have the experiments and practices. these also hare to be planned qwte minutely. Through the experimental process (reality, idea, faculty, discussion, discorery etc.) the experiments and practices teach to the students how to do science. For accomplishment of this purpose, the experimental guidonce must develop as follows. 1. Target of the experiment 2. Mode and time of the experiment 3. Guidance before the experiment 4. Preparation for the experiment 5. Main experiment 6. Guidance after the experiment

徐珠洙 진주산업대학교 1978 論文集 Vol.16 No.-

The progress of the making bean-curd which is made from bean is the steeping water, the grinding, the boiling, the separation and others. After this work tat that raise up some degeneration on the protein of bean is over, this experiment has been carried out to observe the suitable quantity of the calcium sulphate when we add the calcuim sulphate as curdle powder for portein. Then we can economically produce the bean-curd and make the beancurd of good quality. The obtained results are as follows. When the quantity of the steeping bean became near upon two times of the quantity of unhydrous bean, there was very much the contained quantity of protein in the bean-milk. Fron the relation of the quantity of bean and the quantity of calcium sulphate, we can find that the calcium sulphate of 2.5∼3.5g as the curdle powder for protein suit for the bean of one hundred grams.
