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.

The purpose of this study was to assess trophic state of Chinyang Lake using monthly water quility data in 1998, and to suggest adequate protection method of water supply source. The results of water quality variations and trophic states were evaluated as follows; 1. Algae had rapidly grown from June, and this resulted in the increase of pH, Chlorophyll-a and COD. 2. The annual average ratio of COD by algal biomass to total COD was estimated to be 12% and had the highest value of 31.6% in June. 3. The ration of T-N/T-P was 53.7, and phosphorus became the liming factor for the eutrophication. 4. When considering T-P and Chlorophyll-a concentration, Chinyang Lake seems to be eutrophic state. 5. From the evaluation by TSI & LTSI methods, Chinyang Lake could become rapidly into eutrophic state.

Objective: The aim of this study was to investigate the clinical significance of myocardial injuries in patients with nontraumatic intracranial hemorrhage by identifying the occurrence of myocardial injury and defining its correlation with subsequent cardiovascular events. Subjects and methods: One hundred twenty-four patients with nontraumatic intracraninal hemorrhage presented to the emergency department within six hours from onset of symptoms were enrolled. Brain CT, serial electrocardiography, and echocardiography were done at the emergency center. Blood samples for troponin I and creatine kinase(CK)-MB were drawn immediately and eight hours after admission, Troponin I and CK-MB were measured using a chemiluminescent immunoassay, respectively. Results: Electrocardiographic and echocardiography abnormalities were found in 65 cases(52.4%) and 21 cases(17%), respectively. Serum troponin I and creative kinase-MB were increased in 35 cases (28.2%) and in 58 cases(46.8%), respectively. Abnormal findings of echocardiography and ECG, as well as elevated levels of serum troponin I and creative kinase-MB, were associated with an increased risk of cardiovascular event and survival. Logistic regression analysis revealed that an abnormal echcocardiographic finding and elevation of serum troponin I were factors associated with the occurrence an adverse cardiovascular event and that electrocardiographic abnormalities and initial mental status were factors associated with poor prognosis. Conclusion: This study reveals that actual myocardial injury develops in a significant proportion of patients with nontraumatic intracranial hemorrhage and that the development of the myocardial injury is associated with an adverse cardiovascular event that occurs during admission.

As the most 0f informations have time constraints, user must acquire necessary information within the time constraints. To provide information service with time constraints, it is required to support realtime information system including the retrieval of distributed information and the update of the distributed information whenever authorized users try to do in realtime. In this paper. We propose internet information retrieval system model which is applicable on regional information. And we design and implement a realtime controlled search engine for the regional information network. Also, an intelligent robot gathering and updating widely distributed information is implemented. In order to improve the performance of the whole system, a realtime robot control policy is applicable by monitoring the loads of network and a web server on the basis of a statistical model.

It is most important how to select the priorities of cost down elements for cost reduction. Forced evaluation method of product's function is most reasonable tool selecting the priorities of cost down elements for cost reduction than any other techniques. This paper developed the contents as a view point fo V.E (Value Engineering) technique with a case of K.Co. producing water sprayer. This paper would be applied to cost reduction all of the other products.

Computer Interface를 위한 Micro-program에 관한 고찰

姜聲洙 진주산업대학교 1989 論文集 Vol.27 No.-

The input-output subsystem of a computer provides an efficient mode of communication between the central system and the outside environment. Programs and data must be entered into computer memory for processing and results obtained from computation must be recorded or displayed for the user. Input-Output(I/O) interface provides a method for transferring binary information between internal storage, such as memory and CPU register, and external I/O devices. Peripherals connected on-line to a computer need special communication links for interfacing them with the contral processor. The purpose of the communication link is to resolve the differences that exist between the central computer and each peripheral. Microprogramming has many economic advantages. Although hard-wired logic is a more economical way of implementing very simple systems, as the complexity of the system increases, the cost of the control logic increases at a fairly rapid rate. In microprogrammed implementations, the cost of the simplest system in somewhat higher, but adding new features only requires additional control memory. In general, replacing most of the control logic with a ROM affords substantial hardware savings because of the high-density packaging of ROM arrays.

A 21-year-old woman developed painful left third, fourth and sixth nerve palsy. The retro-orbital pain and ophthalmoplegia were improved after steroid pulse therapy. After six weeks, during took steroid by orally left facial weakness developed. Neurologic examination showed left peripheral seventh cranial nerve palsy. The Tolosa-Hunt syndrome associated with facial palsy is rare condition. So we report a case of Tolosa-Hunt syndrome preceded by ipsilateral facial palsy
