Prediction of the soft tissue changes following hard tissue movement is very important from the esthetic view point for patients who have orthognathic surgery. There are many cephalometric analysis of facial bone and soft tissue on the lower lip and chin region but few soft tissue analysis on the midface after mandibular setback surgery. This study was performed to obtain whether the mandibular posterior movement has influence on the midface and the predictable ratio of post-operative measurement values of the soft tissue changes following mandibular setback surgery. Fifteen patients (8 males and 7 females) who had undergone mandibular setback surgery were selected and analyzed the soft tissue movement on the upper lip and the cheek region. Post-operative changes of the soft tissue measurements after mandibular surgery were examined on pre- and post-operative cephalo-metrics and the ratio of changes were analyzed after drawing the reference line on the face with the barium sulfate solution. The reference lines were perpendicular to the intercanthal line from infraorbital foramen and lateral canthus. The results obtained were as follows : 1.There were tendancy of anterior movement of soft tissue adjacent the nose after mandibular surgery 2.There were incerased tendancy of the amount of anterior movement from the nasal crease to the cheek region. 3.The amount of anterior movement of the soft tissue was larger below the palatal plane compared with above the palatal plane in the cheek region. 4.The upper lip length was increased and moved posterior direction after mandibular setback surgery 5.The lower lip was moved posterior direction by posterior movement of the mandibular structure 6.Soft tissue of the midface around the nose moved anterior direction after mandibular setback surgery but there was no correlation between the amount of mandibular setback and the amount of the soft tissue changes

이성태,이영한,최용조,이상대,이춘희,허종수 한국환경농학회 2005 한국환경농학회지 Vol.24 No.1

게르마늄의 약리효능이 알려짐에 따라 게르마늄이 깅화된 기능성 농산물의 요구도가 높아지는 추세이다. 본 연구는 게르마늄의 농업적 이용에 대한 기초 사료를 제공하고자 실시하였으며, 벼의 생육 및 게르마늄 흡수에 미치는 게르마늄처리 효과는 다음과 같다. 게르마늄을 0, 2.5, 5.0, 7.5 및 10.0 mg/kg으로 처리할 토양을 와그너포트에 넣어 벼를 재배힌 결과, 게르마늄 처리농도가 증가할수록 게르마늄 독성의 증가로 초장, 수장, 수수 및 수량이 급격히 감소하였으며 게르마늄 2.5 mg/kg 이상에서는 게르마늄 독성이 발생하였다. 게르마늄 처리농도가 증가할수록 벼의 게르마늄 흡수랑은 증가하였으나 벼의 게르마늄 이용율은 게르마늄 2.5, 5.0, 7.5 mg/kg 처리에서 각각 20.7, 12.5 및 7.5%로서 게르마늄 처리농도가 증가할수록 감소하였다. 벼의 부위별 게르마늄 함량은 볏짚>왕겨>현미 순으로 높았다. 게르마늄 2.5 mg/kg 처리시 볏짚, 왕겨 및 현미의 게르마늄 함량은 각각 103.4, 30.2 및 3.02 mg/kg 이었고, 볏짚과 왕겨에서는 게르마늄 무처리에서도 각각 2.9 및 3.9 mg/kg을 함유하고 있었다. 쌀의 아미노산 함량을 분석한 결과 게르마늄 처리농도가 증가할수록 Asx., Thr., Ser. 등 대부분 종류의 아미노산 함량이 증가하였으며, 그 결과 현미중 질소흡수량도 증가하였다. In order to obtain the basic information for agricultural utilization of Germanium(Ge), the growth characteristics and Ge absorption of rice plant were investigated with different Ge concentration in soil. Ge concentrations were treated with 0, 2.5, 5.0 7.5 and 10.0 mg/kg in pot(1/5,000a), respectively. As higher the Ge concentration in soil, the Ge absorption amount in straw, husk and brown rice were increased. But the yields were decreased with the increase of Ge phytotoxicity. When rice plant was grown more than 2.5 mg/kg Ge(as GeO₂) in the soil, growth was inhibited by germanium phytotoxicity and necrosis spots were observed in the rice leaf blades. Therefore the optimum concentration of Ge was less than 2.5 mg/kg in rice plant. When rice plant was cultivated on soil supplemented with 2.5 mg/kg Ge, Ge content in straw, husk and brown rice was 103.4, 30.2 and 3.02 mg/kg, respectively. The Ge content in plant was high in the order of straw > husk > brown rice. Most of the amino acids in rice were increased with the increase of Ge treatment, besides, total amino acid contents also increased.

김지태,한명애,곽현,배성렬 漢陽大學校 工學技術硏究所 2000 工學技術論文集 Vol.9 No.1

이취미물질중에서 페놀, Geosmin, 2-MIB를 선정하여 응집제(PACS)와 흡착제(PAC) 및 산화제(Cl2, ClO2)로 처리하였을 때 제거율을 알아보았다. 페놀의 경우 이산화염소(ClO2)와 분말활성탄(PAC)으로 처리하였을 때 제거효율이 높았고, Geosmin과 2-MIB는 분말활성탄(PAC)으로 처리하였을 때 제거효율이 높았다. 그러나 페놀, Geosmin, 2-MIB 모두 응집제(PACS), 염소(Cl2)로 처리하였을 경우에는 제거효율이 거의 없음을 알 수 있었다. The removal ratio of phenol, geosmin, and 2-MIB selected in odor and taste causing materials was investigated, when water was treated with coagulant(PACS), adsorbent(PAC), and oxidants(Cl2, ClO2). Phenol was removed at a relatively higher rate by the treatment with CIO2 and PAC(Powder Activated Carbon). The other side, geosmin and 2-MIB were removed at a higher rate by the treatment with PAC. But it was found that the treatment with coagulant(PACS) and chlorine(Cl2) for the removal of phenol, geosmin and 2-MIB was little removal efficiency.
