家畜排泄物 콤포스트化 有效利用에 關한 硏究

洪志亨,全炯柱,朴又龍,崔秉旻,金在煐 順天大學校 1983 論文集 Vol.2 No.1

家畜排泄物의 堆肥化 작업체계의 工學的인 局面은 畜産經營의 畜産物 生産性, 에너지保存, 公害防力및 勞動力 節約에 密接한 關係를 갖고 있는 바이다. 그러나 韓國에 있어서 現在 畜産業의 飼養規模와 飼育頭數는 每年 增加하는 傾向을 나타내고 있으나, 傳統的인 家畜排泄物의 堆肥化處理 加工作業上의 問題點에 關한 硏究資料는 거의 없는 實情으로 堆肥化 작업체계 改善確立이 切實히 要求되고 있다. 따라서, 本硏究의 目的은 家畜排泄物 堆肥化 작업체계상의 工學的인 諸問題點을 調査分析하고 이에 對한 現況을 評價하여 改善方案을 模索하기 위한 基本資料를 提供하기 위해 遂行되었으며 調査分析 結果를 要約하면 다음과 같다. 1. 畜産農家의 家畜排泄物 處分方法으로는 大部分이 自然乾燥, 堆積, 嫌氣的 固形堆肥化에 依하여 遂行되고 있어 家畜糞尿에 의한 公害가 深刻해 지고 있었다. 2. 野積堆肥化 가공작업체계에 있어서는 트랙터에 附着된 前後作動式 로우더가 바람직하다. 3. 好氣性 野積堆肥化 加工作業에 따른 良質의 腐熟堆肥를 얻기 위해서는 外部氣溫에 따라 適正通氣量을 維持하기 위해 3∼7日 間隔으로 混合攪拌해야 되며 氣象條件에 의한 影響을 防止하기 위하여 堆肥作業物質의 表面을 비닐 等으로 덮거나, 더운날에는 加水를 해야할 것이 要望된다. 4. 堆肥化 加工作業體系의 基本段階別로 이루어지는 畜産農家는 거의 찾아 볼 수가 없었다. 5. 堆肥化加工 過程은 畜産農家周圍의 콤포스트센타에서 全體農家가 地力增進과 公害防止를 위해 參與할 수 있는 總合的이고 協同的인 加工作業體系로서 一貫性있게 遂行되어야 할 것으로 思料된다. There was almost no livestock farms to follow the basic stage in composting operation system. Composting disposal process should be performed successively an integrate cooperative operation system at compost center which is participated in all farmers near the livestock farms for the purpose of land improvement and pollution abatement. Well matured compost which is resulted from aerobic windrow solid composting should be turned at 3 to 7 days to insure abequate aeration according to the ambient temperature. The compost material should be covered with vinyl sheets etc. to avoid the effect of climatic condition.

Objectives : Obsessive compulsive disorder (OCD) tends to take chronic course as schizophrenia. Researchers reported that OC patients had idiosyncratic sensitivity to threat-related information, while schizophrenic patients were reported to have affec-tive blunting. We hypothesized that there might be a difference in emotional response between OCD and SPR in cronic phase. Methods : Eight different emotional tasks were done by 25 healthy controls, 21 OCD patients and 25 SPR patients. Visual stimuli were made by pairing two words or pictures. Four kinds of emotional stimuli (positive, negative, combined and neutral)were presented to subjects through monitor and they were asked to report their subjective feelings by pushing mouse button, In the combined condition, a pair of positive words (or pictures) and negative words (or pictures) were presented simultaneously. The responses and response time were recorded and analyzed using SPSS 9.0 package. Results : In the negative condition, OCD group didn't show any deficit compared to healthy group. But SPR group showed significantly lower appropriate response rate than healthy group, In the combined condition, OCD and healthy control group Showed 'negativity bias' which SPR group didn't show. In the positive condition, however, OCD and SPR groups did show Significantly lower appropriate response rate than healthy controls. Conclusion : Our results suggested that OCD patients may not have deficits in the processing of negative emotion even in the chronic phase but to have a specific deficit in positive emotion. This result supports the 'threat-relatedness hypothesis' on attentional bias of OCD.

1. 하순에 심한 self-mutilation wound를 야기한 Lesch-Nyhan Syndrome 환아에서 상하악 유전치에 치관부 절단 및 치수 절세술을 시행하여 치아에 의한 자해를 방지하였다. 2. 장치를 이용한 치료가 어려운 경우 발치가 고려되기도 하나 본 증례에서는 발치보다 보존적인 술식으로 만족할 만한 결과를 얻었다. Self-injurous behavior is defined as deliberate harm to one's own body without suicidal intent. It usually occurs as head banging or hitting, skin cutting, or finger biting and includes ocular, genital and oral self-mutilation. Lesch-Nyhan syndrome is a rate X-linked recessively inherited disorder, caused by complete absence of hypoxanthin-guanine phosphoribosyl transferase(HPRT) activity. Clinical presentation is characterized by mental retardation, chorea, athetosis, hyperuricemia, uricosuria and self-mutilating behavior. In these patients, the most typical feature is loss of tissue from biting themselves, even though they are not insensitive to pain. The dental management of self-mutilation includes treatment with appliances such as soft mouthgrard or lip bumper, extraction of all the teeth, and orthognathic surgery. We report a 25-month-old boy who was a known case of Lesch-Nyhan syndrome and presented with severe self-mutilation wound on his lower lip. Vital pulpectomy and coronal resection was done as a more conservative approach than extracting all primary anterior teeth. Due to maintaining the root portion of the teeth in the bone, it is expected that the normal growth of the alveolar bone will be achieved.
