Pulmonary edema is a well known phenomenon in medicine, physical findings indicative of this condition include frothy pink sputum, dispnea, and chest X-ray may present cephalization of vessels, perihilar edema, or diffused increase of density. It is one of the most serious, life threatening situation and should be diagnosed and managed instantly. Early diagnosis and intensive treatment are mandatory in order to effectively resolve the situation. The most common etiology for this pathology is cardiogenic, such as left ventricular failure and valvular disease. The one following is noncardiogenic, such as transfusion, infectious pneumonia, inhaled toxins, shock lung in association with trauma. Other forms of pulmonary edema which have not been clearly explained result from pulmonary embolism, drug overdose, after anesthesia, epinephrine overdose, exposure to high altitude, neurogenic, etc. We experienced two cases of pulmonary edema during two jaw surgeries(Le Fort I Osteotomy & BSSRO). These patients were young and physically healthy individuals on preoperative evaluation. Thus we report and discuss the etiology, diagnosis, prognosis, and treatment with journals review. 폐부종은 구강악안면외과 영역의 수술 도중에 발생할 가능성이 있다. 따라서 전신마취하에 수술중인 외과의와 마취의는 환자의 상태를 주의깊게 관찰하여야 하며 수술 중 폐부종이 발생할 가능성에 항상 대비하여야 한다. 폐부종 증세가 발견되는 즉시, 즉각적이고도 적절한 처치를 시행한 경우 예후가 좋으며, 근본적인 원인치료 및 타장기의 합병증 및 후유증에 대하여 검사가 필요하다.

This study evaluated the antioxidant activity and quality characteristics of rice cookie with added butterbur powder in a ratio of 0, 5, 10, 15, and 20% to confirm the possibility of butterbur as a functional food. The moisture content, spread factor, leavening rate, and hardness of rice cookies increased with an increase in the amount of butterbur powder; whereas a decrease in the pH and baking loss rate was observed. The L and b values decreased as the amount of butterbur powder increased, but the value was the lowest when 5% of butterbur powder was added. The sensory liking score showed the highest preference for 10% butterbur powder regarding appearance, flavor, taste, texture, and overall preference. In the principal component analysis (PCA), the addition of 10% butterbur powder positively affected the measure of food acceptance in terms of organoleptic properties of butterbur. Besides, as the amount of added butterbur powder increased, the antioxidant activity of rice cookies increased. Based on these results, it appears that the addition of butterbur powder to rice cookies in a 10% ratio can produce rice cookies with excellent antioxidant activity, overall quality, and high preference.

본 연구의 목적은 제 IV형 근관에서 Continuous Wave 가압법을 이용하여 충전할 때 System B Plugger tip의 깊이에 따른 근단부 밀폐효과를 평가하기 위함이다. 50개의 J형 만곡을 갖는 레진 블록에 부러진 F3 ProTaper 파일을 이용해 근관장에서 3mm 지점에 ledge를 형성한 후, F1 ProTaper Ni-Ti file을 이용해 레진 블록을 천공시켜 제 IV형 근관을 형성하고 System B Plugger tip의 깊이에 따라 3개의 실험군과 1개의 대조군으로 분류하였다. 제 IV형 근관의 거터퍼쳐와 실러의 길이는 확대경하에서 캘리퍼를 이용해 측정하였고 다음과 같은 결과를 얻었다. 1. 대조군의 설측 근관에서 거터퍼쳐와 실러 모두 관찰되지 않았다. 2. 3 mm군에서는 5 mm 또는 7 mm군에 비해 유의하게 많은 거터퍼쳐의 충전이 관찰되었다 (p<0.05). 3. 7 mm군에서는 유의하게 많은 빈 공간이 관찰되었다 (p<0.05). The purpose of this study was to evaluate the effect of the apical sealing according to the depth of the System B Plugger tip when root canal was filled with gutta-percha and sealer by Continuous Wave of Condensation technique in the Type IV canal. 50 simulated resin blocks with J-shaped curvature canals were instrumented by ProTaper (Dentsply Maillefer, Ballagiues, Switzerland) Ni-Ti files using the crown-down technique. Type IV canals were made using a broken ProTaper F3 Ni-Ti file for making a ledge at 3mm short from the working length. And ProTaper F1 Ni-Ti file was used for perforating resin block. The prepared Type IV canals were randomly divided into three experimental groups of 15 each according to the depth of System B Plugger tip. All of experimental groups were obturated with Continuous Wave of Condensation technique. The length of gutta-percha and sealer in lingual of the Type IV canals was measured with a measuring digital calliper under magnifying glass (${\times}2.3$). The results are as follows : 1. In control group, there was no gutta-percha and sealer in lingual canal. 2. 3 mm group showed relatively more gutta-percha than 5mm or 7 mm group (p<0.05). 3. 7 mm group did not showed gutta-percha and relatively more void were observed than 3mm or 5 mm group. (p<0.05) In conclusion, within the limits of the results of this experiment, the 3 mm depth of System B Plugger tip was acceptable for obturating the Type IV canal.

The purpose of this study was to compare the postoperative stability and relapse according to 2 different fixation methods after bilateral sagittal split ramus osteotomies in mandibular prognathic patients. Tweenty one patients with Class III dental and skeletal malocclusion who were treated with bilateral sagittal split ramus osteotomy were selected for this retrospective study. We classfied the patients into two groups according to the fixation methods of bony segments after osteotomies. Group W (n = 10) had the bone segments fixed with nonrigid wire and Group S (n = 11) had bicortical screws inserted in the gonial area through a transcutaneous approach. Cephalometric radiographs were taken preoperatively, immediate postoperatively and more than six months postoperatively in each patient. After tracing the cephalometric radiographs, various parameters were measured. Before surgery, both groups were balanced with respect to linear and angular measurements of craniofacial morphology. Mean posterior sagittal setback amounts of the mandibular symphysis was 8.6 mm in the wire group and 6.79 mm in the rigid group, Six months postoperatively, the wire group had 33.1% relapse of the mandibular symphysis and 22.8% in the rigid group relapse. Both groups experienced changes in the orientation and configuration of the mandible. It is thought that Rigid screw fixation is a more stable method than nonrigid wire fixation for maintaining mandibular setback after sagittal split ramus osteotomy.

CEO 변혁적 리더십 특질과 기업의 재무성과가 CSR에 미치는 영향

최희원(Choi, Hee Won),문철우(Moon, Chul Woo) 한국인적자원관리학회 2011 인적자원관리연구 Vol.18 No.2

In recent years, many scholars have discussed Corporate Social Responsibility(CSR). The CSR includes business ethics, corporate governance, accounting and trading transparency, labor relations, community involvement, and relationships with suppliers. Researchers are expanding the concept of CSR to sustainability. Companies tend to use CSR as a strategic choice for competitive advantage. Previous studies indicate that CEO intellectual stimulation was found to be associated with the strategic CSR. There are many researches on the relationship between financial performance and CSR. This study analyzed empirically CSR cases of Korean companies based on the conclusions of previous studies. The results of this study show that CEO charisma is associated with social CSR positively and CEO intellectual stimulation is also associated with strategic CSR positively. We find out Korean companies are carried out CSR for the purpose of both strategic management and social purposes. Financial performance of a company has partially positive relationship with CSR. This means that at a strategic level, it is necessary to access the company’s CSR for competitive advantage. We suggest further research on the relationship between various aspects of leadership and CSR and the causal relationship between financial performance and CSR in detail. Above all, it is important to develop CSR measures to ensure the validity and the credibility of measurements which is socially acceptable. 최근 기업의 사회적 책임(CSR)에 관한 논의가 지속적으로 이루어지고 있다.CSR의 범위에 기업윤리, 지배구조,회계 및 거래투명성,노사관계,환경·안전·위생,사회공헌,협력업체와의 관계 등이 포함되고 있고,지속가능경영을 포함하는 개념으로 확대되고 있다.CSR이 기업의 전략적 선택으로 활용되는 경향이 있으며,외국의 선행연구에서 CEO의 지적자극이 전략적 CSR에 정(+)의 영향을 미친다는 것이 검증되었고,기업의 재무성과와 CSR간에 정(+)의 관계가 존재한다는 연구들이 진행되고 있다.본 연구는 선행연구의 결론을 바탕으로 국내기업을 대상으로 실증분석 하였다.분석결과 CEO의 카리스마는 사회적 CSR과,지적자극은 전략적 CSR과 정(+)의 관계가 있다는 것을 검증하여,국내기업의 CSR은 경영전략적 측면과 여유자원의 재량적 기부와 같은 사회적 측면에서 동시에 수행되고 있다는 것을 밝혔다.또한 기업의 재무성과와 CSR간의 정(+)의 관계를 부분적으로 검증하여,기업의 경쟁우위 확보를 위한 전략적 차원에서 CSR을 접근할 필요가 있다는 것을 제시하였다. 향후 CEO의 변혁적 리더십 특질 외의 다른 리더십 특질이 CSR에 어떤 영향을 미치는지에 대한 고찰과 기업의 재무성과와 CSR간의 관계에 대한 추가적인 연구가 필요하며,무엇보다 CSR측정의 일관성 확보를 위해 사회적으로 합의된 CSR 지표 개발이 중요하다 하겠다.
