The need for rapid diagnosis and treatment of life-threatening thoracic and intra-abdominal injury result in controversy over the appropriate triage of unconscious blunt trauma patients. To aid in early decisions for these patients, a prospective analysis of 98 patients with glasgow coma scale(GCS) scores≤8 was undertaken. Although intra-thoracic and intra-abdominal injuries were frequently identified based on systolic blood ressure, the use of clinical signs alone resulted in more missed injuries than did using the emergency ultrasonography. In normotensive patients(n=34), intra-thoracic injuries was identified in one patient(2.9%), and intra-abdominal injuries were in 7 patients(20.6%). In shock(systolic blood pressure<90mmHg) Pa-tients(n=64), thoracic injuries and intra-abdominal injuries were diagnosed in 8(12.5%) and 27 patients(42.3%), thoracic and abdominal combined injuries were identified in 11 patients(17.2%). The sensitivity, specificity, and accuracy of emergency ultrasonography were 96.3%, 91.7%, 94.9%. This study suggests that all unconscious trauma patients undergo immediate emergency ultrasonography to prevent missing life-threatening injuries.

This study is to follow the studies, which were conducted in Moon island between July and October in 2010. The previous studies, which were conducted by Lim, Hyun-soo and Kang Eun-suk in 2010, studied the current status of education of divers by classifying it into five subjects such as diving science, diving equipment, diving safety, underwater environment, and diving activities through FGI of expert groups. Being aware of the lack of materials about the observation of non-fulfillment of education on diving equipment and underwater environment and interviews, we made visits to the spots where the previous studies were conducted between July 28 and August 2nd to newly add up materials on interviews and questionnaires and analysed the cause and problems of the educational non-fulfillment about diving equipment and underwater environment. The educational non-fulfillment about diving equipment resulted in inappropriate management of equipment and loss of equipment, immature assembly of equipment of equipment, the loss of waist belts, and diving knife"s inappropriate use. The educational non-fulfillment about underwater environment brought about the damage of underwater environment, panic by underwater environment, conflicts with fishing villages, and the problems of trash-littering and defecation.

본 연구는 후두적출자의 주된 발성방법과 후두적출 경과 시기에 따른 의사소통 태도를 살펴보고자 하였다. 연구의 대상은 성인 남자 55명으로 후두암으로 인한 후두적출자들로 구성되었다. 이들에게 실시한 의사소통 태도 설문지는 Erickson의 의사소통 태도 척도-수정판(Modified Erickson Scale of Communication Attitudes: S-24)을 본 연구에 맞게 수정 보완하여 사용하였다. 본 연구의 결과는 첫째, 주된 발성방법에 따라서는 인공후두기 사용자와 식도발성자간의 의사소통 태도에 차이가 없었다. 둘째, 후두적출 경과 시기에 따라 10년 초과된 후두적출자들과 10년 이하의 후두 적출자들 간의 의사소통 태도에 차이가 없었다. 그러므로 이들의 의사소통 태도의 긍정적 태도를 증가시키기 위하여 다양한 방법을 활용하고 습득하여 이들의 의사소통 능력을 빠르게 재습득 하여 긍정적인 의사소통 능력을 가질 수 있도록 해야 한다. The purpose of this study was to determine laryngectomee's communication attitude. 55 laryngectomees, who were in the range of 40 years old to 80 years old participated in the study. Communication attitude measurements were taken by S-24(Modified Erickson Scale of Communication Attitudes). The results showed as follows: First, score of laryngectomees with artificial larynx and esophageal speakers were no significant. Second, score of laryngectomees with over 10 years after latyngectomy and 10 years after latyngectomy were no significant.

탄수화물로부터 유도된 불포화 퓨라노스 고리계를 입체 선택적인 수소화 반응에 의해 chiral synthon인 광학활성의 (S)-3-포르밀옥시 알데히드를 합성하였고, 탄수화물에서 유도된 3-히드록시 퓨라노스를 Barton-McCombie의 deoxygenation반응에 의해 (R)-3-포르밀옥시 알데히드를 합성하였다. (S)-e-Formyloxyaldehydes, chiral synthons for natural products, were synthesized via highly stereoselective hydrogenation of the unsaturated furanose ring system derived from D-glucose or D-xylose. Alternatively, (R)-3-formyloxyaldehydes were prepared via deoxygenation of 3-hydroxyfuranoses.

Gastric carcinoma is the most common malignant tumor in korea and many oncogenes have found in gastric carcinoma. The relation between the expression of p53 and c-erbB-2 and the prognosis of patient in gastric adenocarcinoma have studied recently, but it is controversy. To evaluate correlation between the pathologic findings including prognostic factors and the expression of p53 and c-erbB-2, and DNA ploidy, we have performed immunohistochemical staining using 83 cases adenocarcinoma and flow cytometry with 56 cases. The results were as follows; 1) The expression rate of p53 was 45.8% in gastric adenocarcinoma. Differentiated, intestinal, advanced, and lymph node metastatic cases showed higher expression rates than poorly differentiated, diffuse, and non-metastatic cases, without statistically significance. 2) The expression rate of c-erbB-2 was 62.6% in gastric adenocainoma. c-erbB-2 was related to differentiated and intestinal types. Advanced and metastatic cases showed higher expression rates of c-erbB-2 than early and non-metastatic cases, but there was not statistic significance 3) Gastric adenocarcinoma showed correlation of DNA diploidy with poorly differentiated type and aneuploidy with differentiated. 4) DNA diploidy and aneuploidy showed correlation with c-erbB-2 negative and postive cases respectively, but correlation between DNA ploidy with p53 expression was not proved. Above results showed that p53 and c-erbB-2 may be related poor prognosis but there was no statistic significance. DNA aneuploidy and diploidy showed correlation with c-erbB-2 expressed and non-expressed cases, respectively, but not with p53 expression.

골격성 Ⅱ급 성인 부정교합자에서 혀와 두개안면골격 및 악간공간과의 상관관계에 관한 연구

강현희,박수병 대한치과교정학회 1999 대한치과교정학회지 Vol.29 No.5

골격성 Ⅱ급 부정교합자 중 성장이 완료되었다고 생각되는 만 18세 이상의 여자 37명, 만 20세 이상의 남자 23명을 선정하여 정상 성인의 안면비를 기준으로 hyperdivergent group(n=30)과 hypodivergent group(n=30)으로 나누어 두부 방사선 규격사진의 투사도를 작성하였으며 두개안면골격 및 혀의 크기, 높이 그리고 자세를 나타내는 항목을 계측하였고, 두 군간의 차에 대한 유의성 검정 및 혀와 두개안면골격 그리고 악간공간 사이의 상관관계를 조사하여 다음과 같은 결론을 얻었다. 1. 두 군의 혀와 악간공간의 계측항목 비교시 악간공간에 대한 혀의 면적비(TS/IS)는 hyperdivergent group에서 더 크게 나타났으며, PIH(posterior intermaxillary height)와 IS(intermaxillary space)는 hypodivergent group에서 더 크게 나타났으나 혀의 높이와 자세를 나타내는 항목에서는 두 군간에 유의할 만한 차이가 없었다. 2. 혀와 두개안면골격의 상관관계 비교시 두 군 모두에서 혀의 면적(TS), 길이(TGL) 그리고 높이(TH)를 나타내는 계측 항목이 전안모고경(AFH)과 가장 높은 상관관계를 나타냈으며, 또한 hypodivergent group에서는 후안모고경(PFH)과도 높은 상관성을 보였다(p<0.01). 3. 혀와 악간공간의 상관관계 비교시 두 군 모두 혀에 관한 대부분의 항목(H-P제외)이 악간공간(IS)과 가장 높은 상관성을 보였으며, 혀의 높이(TGH)와 면적(TS)을 나타내는 항목은 악간공간의 AIH 및 PIH와 높은 상관성을 보였다(p<0.01). This study was designed to evaluate the correlations between tongue with skeletal pattern and intermaxillary space in Class Ⅱ malocclusion adult patients. Craniofacial skeletal pattern was analyzed on the lateral cephalometric radiograph and the subjects were devided two groups by facial ration, the 30 subjects of hyperdivergent group and the 30 subjects of hypodivergent group. The size and posture of tongue and intermaxillary space were measured on the lateral cephalometric radiograph. These data were statistically analyzed to examine significant differences between both groups and compared the correlation between tongue with skeletal measurements and intermaxillary space in each group. The results of this study were as follows.: 1. In comparison of the tongue and intermaxillary space, the measurement of TS/IS showed significantly larger in hyperdivergent group and PIH and IS showed significantly larger in hypedivergent group. There were no statistically significant differences in the measurements of the height and posture of tongue. 2. In correlation between tongue with craniofacial skeletal measurements. the length and height of tongue showed the highest correlation with AFH(anterior facial height) in both groups(p<0.01). And that measurements showed high correlation with PFH(posterior facial height) in hypodivergent group. 3. In both groups, most measurements of tongue showed high correlation with intermaxillary space and the height and space of tongue showed high correlation with AIH and PIH(p<0.01).

Modal SI 기법 적용을 위한 최적 측정위치 선택

강태우,권순정,김용현,신수봉 東亞大學校 建設技術硏究所 2001 硏究論文集 Vol.25 No.2

In applying a modal system identification with a limited number of measuring degrees of freedom, the selection of optimal sensor locations (OSL) is critical for a good identification. The current research proposes a new OSL method applicable to a modal system identification (SI) and compares it with a widely used OSL method. The proposed method utilizes the sensitivity of eigenvectors with respect to the structural parameters. A simulation study for a tower structure has been carried out to demonstrate the efficiency of the proposed method. Through the simulation study, the influence of OSL on the structural parameters estimated by a S1 method are investigated.
