The Evaluation of blunt abdominal trauma is clinically challenging. Abdominal computed to-mography(CT) and diagnostic peritoneal lavage(DPL) has become primary diagnostic modali-ty in advanced trauma life support(ATLS). But DPL is invasive study with potential for the patients. Monitoring and resuscitation are usually suboptimal during there examinations. We examined the efficacy and role of emergency ultrasonographic(US) studies in the initial abdominal evaluation of blunt trauma patients. A prospective study was carried out on 101 blunt trauma patients from 1994, June to September. 101 patients underwent real-time US ex-amination of the chest and abdomen. Indication for emergency US included the cases of shock (systolic blood pressure<90mmHg) or tachycardia (pulse rate/min.>100) in blunt trauma pa-tients. US showed a sensitivity of 96.2%, specificity 98%, accuracy 97% in regard to indica-tion for surgery in case of blunt abdominal or thoracic trauma. US saves time, and it can be performed during the emergency care in the emergency department. US showes high sensitivity and specificty, and is the method of first choice in the evaluation of blunt trauma.

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.

Reactions of copper(In complexes of 1, 8-dimethyl-, 1, 8-diethyl-, and 1, 8-dipropyl-1, 3, 6, 8, 11, 13-hexaazacyclotertradecanes(A, B, and C, respectively) with halide and pseudohalide ions have been studied in aqueous solutions by spectrophotometric method. It is observed that the equilibrium constants(K) of these reactions decrease with the ligand structure in the order A> B>C for anions and decrase with the anions in the order SCN^(-)>N_(3)^(-)>Br^(-)>Cl^(-) for complexes. The values of K increased with increasing temperature. Thermodynamic parameters obtained from the equilibrium constants are investigated.

製品의 Life Cycle을 고려한 最適 設備投資政策의 決定

姜聖壽 慶南大學校 附設 工業技術硏究所 1987 硏究論文集 Vol.5 No.-

本 硏究는 製品의 Life Cycle을 고려하여 複數의 Alternatives 中에서 全體의 投資利益을 最大로 하는 最的 Alternative를 선정하는 方法과 절차를 제시하고 있다. 이 방법을 使用함으로써 전통적 損益分岐圖表에 의한 B·E·P 分析및 損益의 計算에 의한 方法보다 合理的인 投資代案을 선택할 수 있을 뿐만 아니라 보통의 代贊案의 比較선택 방법보다 많은 노력과 時間을 줄일 수 있다. This study represents the method & procedure of selecting the best one alternatives among multiple alternatives which maximizes the total profits of investment under consideration of product's life cycle. By using this method we have advantage of reducing more efforts and time of selecting the best one alternative than simple comparing method of evaluating the value of annual equivalent cost of alternatives and we have advantage of selecting more reasonable alternative than the method of selecting alternative by comparing B·E·P and profit of conventional B·E·P chart method.

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.

This study is concerned with characteristics of bending collapse of aluminum members with multi-cell section. Aluminum is light so it is compatible of being used for vehicle structures members. Bending collapse behaviors of aluminum members with multi-cell section are very complex and tension failure mode are occured in experiment. In this paper, the aluminum members are modeled to be able to represent the tension failure mode and, characteristics of bending collapse of aluminum members with multi-cell section by experimental method are compared with the results of PAM-CRASH.

컴퓨터과학을 전공하는 학생에서 컴퓨터의 기본 동작 구조에 대한 이해와 실험을 가능하게 하는 것은 중요한 의미를 가진다. 이를 위해 간단한 가상 모의시스템인 ASSESS를 구현하였다. 본 고에서는 ASSESS의 구조를 내부 구성요소와 그들 사이의 자료 흐름을 살펴본 후, 구현된 어셈블러의 실험환경, 운영 및 형식과 목표 구조의 측면에서 서술하였다. ASSESS 어셈블러는 컴퓨터시스템 개론 과목의 실험환경의 확장을 도모함과 동시에, 시스템 프로그래밍 개론 과목과 어셈블러 교육을 위한 기본 모형으로 활용되어 질 수 있다. 그리고, 부과적으로 XENIX환경을 직접 호출하는 shell기능을 추가하였다. ASSESS는 시스템 소프트웨어 교육의 초보 단계의 이해를 위해 구성되었다. 따라서 실제 컴퓨터 구조에 가까운 구조의 이해를 효과적으로 제공하기 위해, 다음의 확장을 위한 방법이 앞으로의 연구 과제이다. 1) BOE console의 그래픽 환경 2) 다양한 주소지정 방식 3) 구조적 프로그래밍을 위해 부프로그램을 위한 구조 4) 프로그램 실행과정을 추적하기 위한 도구 5) 사용방법 및 실험진행에 관련된 문서화 교육적 목적이외에도 현대적 시스템에서 고려되고 있는 멀티프로세서 시스템, 분산시스템, RISC구조 등에 대한 모의시스템 연구가 ASESS의 확장을 통해 진행된다면, 앞으로의 시스템 구조에 관한 연구 활동에도 많은 효과가 기대된다. It is important for beginning students who major in computer science to understand the basic operation structure of computers and take a laboratory. As a method to obtain the merits in views of laboratory environment and educational effects. we implemented ASSESS which simulates a simple hypothetical computer. After this paper in introduced ASSESS architecture through internal components, flows, and implemented ASSESS assembler is described in the environment of operation, and format and operation of assembler and target architecture. ASSESS assembler have set about expansion a laboratory environment in the course of introducing computer system, and a fundamental model for simulator implementation project in the course of introducing systems programming and for education on basic assembly language
