Today, the core achievements of university education are changing from how many students are exported to society and how much education services are provided to improve the university`s service quality, education service and learning outcomes. In particular, universities should shift from provider-centered thinking to consumer-centered thinking. Therefore, this study examined the relationship between educational satisfaction, learning outcome, and quality of education service in Yanbian University in China. The findings showed that factors such as university credibility, service consciousness and enthusiasm, lecture competency, educational facilities, welfare facilities and traffic conditions have positive effects on educational satisfaction. However, the moderation effect of learning outcomes on the quality of education service and the satisfaction of education was less than expected. As a result of the study, Yanbian University should be built and improve the service quality of the school by improving the satisfaction of the students, to grasp the service demand and trend of students and parents, to improve the education service system.

For the emergency patients in need of immediate resuscitation, cardiac catherization along with intensive cardiac monitoring is necessary to evaluate the cardiovascular stability. But this method requires machinery, technique and time which limits its use in emergency situations. In 1961, Allgower and Buri first discribed shock index, heart rate divide by systolic blood pressure, as easy to calculate and easy to use in acute settings given the simple measurements of the heart rate and the blood pressure. It has been said in circulatory failure patients shock index is inversely related to left ventricular stroke work. Because shock index is an indicator for resuscitation and also a prognostic indicator it could be applied in triaging an emerency patients. Therefore we studied the significance and the possible triage application of shock index in emergency patients. In the period of 6 months from May 1 to October 31, 1994. Among total 15,782 patients, who visited Yonsei University-affliated Yong Dong Emergency Department, 2425 patients were included in the study. There were 201 admissions to the intensive care unit and 2105 patients to general beds and 199 selected patient from discharged. Retrospective chart review for pulse rate, systolic blood pressure, diastolic pressure and shock index was done. Statistical analysis was performed using t'-test, p value of less than 0.05 was designated significant. Average shock index for ICU patients were 0.96 ±0.50, general ward admittees were 0.67 ±0.18, and discharged were 0.65 ±0.16. There were significant statistical difference in shock indices between ICU and general ward patients, and ICU and discharged patients. Shock index is helpful in identifing patients with potential for admission to the ICU in emergency situations. Therefore we conclude that the shock index should be recognized as a triage tool.

Background: Traumatic death occupies a high ranking in the annual national report on causes of death and causes a significant burden to society. To reduce traumatic death, an area-wide trauma care system is urgently needed, and basic mortality data will be an essential component in designing such a system. The purpose of this study was to review the experience of trauma death in a hospital to determine the pattern of time to death and the effect of the emergency medical services(EMS) system in traumatic death. Methods: A retrospective analysis of 495 traumatic deaths experienced from 1990 to 2000 was performed. Time to death, mechanism of injury, injury severity, and cause of death were reviewed. The influence of the EMS system before 1995 was compared with its influence after 1995. Results: The mean age of the 495 patients was 41.1±18.9 arid the mean injury severity score(ISS) was 37.1±17.8. The distribution of time to death showed DOA(including found dead) in 39% of the cases, within 48hr in 38.4%, between the 2nd and 7th days in 9.9%, and later than the 7th day in 12.7%. The majority of early deaths occurred within 4 hr of injury, but a minor increase was noted during the 2nd week. After 1995, the ambulance transportation rate increased significantly without any difference in prehospital interventions. Conclusion: Our results showed a bimodal distribution of time to death, which reflected geographic, mechanism of injury, and trauma care system differences. We also noted deficiencies in prehospital trauma care in our EMS system. We recommend nationwide trauma registry initiatives to provide basic trauma data and to implement a quality trauma care system.

Background. Tetanic spasm is often noted in hyperventilating patients coming in to emergency departments. Classical explanation for this phenomenon was decreased ionized calcium levels due to respiratory alkalosis precipitated by the hyperventilation. Clinically these symptoms were observed in hypocalcemia and were thought as such without doubt, But6 clinical investigation on the levels of ionized calcium levels have not been clarified. Recent investigations on hyperventilating volunteers have suggested other pathophysiology for tetanic spasm in hyperventilating patients which is the decrement of ionized magnesium level rather than ionized calcium. We wanted to see if these results applied to our hyperventilating patients and see if ionized magnesium level was a factor producing tetanic symptoms. Method and Material, 35 patients with diagnosis of hyperventilation syndrome by emergency physician were studied retrospectively. Hyperventilating patients arriving at Severance hospital Emergency Center from Jan. 1996 to Feb. 1998 were included. Patients with cardiovascular, pulmonary diseases, history of renal or liver disease were excluded. Ion-selective method was used to detect ionized calcium, magnesium levels and arterial blood gas features. Average levels were compared to reference ranges and Wilkoxon-rank, sum test was used to compare hyperventilating patients with tetanic spasm and those with other symptoms such as dyspnea, chest pain and palpitations. Results. 1) Sodium, potassium and chloride levels were 138mmol/L, 3.6mm/l, 106mm/l each which were within a normal range. 2) Degrees of hyperventilation were similar with average of PH 7.54(7.4-7.71), pCO₂ 23.6mmHg, showing respiratory alkalosis. 3) Ionized calcium and ionized magnesium each showed 0.61mg/dl, 0.16mg/dl lower values than the lowest reference ranges which were 4.5-5.6mg/dL for ionized calcium and 1.19-1.63 for ionized magnesium. 4) No statistical difference points were observed between the tetanic spasm group and group without spasm. Female preponderance were noted in tetanic spasm group. Conclusion. We conclude that other than decrement of ionized calcium, decrement of ionized magnesium could be a factor for inducing tetanic spasm in respiratory alkalosis caused by hyperventilation.

Major factors influencing the outcome after cardiopulmonary resuscitation(CPR) of cardiac arrest patients are the technique of CPR, response time and early defibrillation. Others like patient's characteristics and drugs used in resuscitation play minor role. To determine if the emergency physician affects the outcome of CPR, 318 consecutive victims with cardiac arrest who CPR were attempted in emergency room. The results were as follows : 1. The first group without emergency physician was 102 patients and the second group with emergency physician was 216 patients. 2. Among the factors affecting the outcome of CPR, patient's characteristics(sex, age, cause, injury severity score), prehospital factors(response time, use of ambulance, prehospital care) and the duration of CPR have no statistical differences between two groups. 3. Among the prehospital cardiac arrest patients and whom arrested in emergency room, use of defibrillation does not showed statistical differences between two groups. 4. The statistically significant factors(p<0.05) between two groups were initial defibrillation energy, defibrillation frequency and drugs like epinephrine, atropine and lidocaine. These results were similar among the prehospital, in-emergency room and the total cardiac arrest patients. 5. The outcome of CPR showed no significant differences on prehospital cardiac arrest patients analysis of all the data, there were no significant factors affecting the outcome of the CPR except the role of emergency physician. 6. Low survival rate(1.9%) on group Ⅱ, reflect the lacking of other important factors affecting the CPR other than emergency personnel. In conclusion, the involvement of full time emergency physician on CPR is an important factors in resuscitation of arrested patients in emergency room.

A Proteomic Analysis of Leaf Responses to Enhanced Ultraviolet-B Radiation in Two Rice (Oryza sativa L.) Cultivars Differing in UV Sensitivity

To determine the proteomic response to UV irradiation, two cultivars, i.e., Lemont (UV tolerant) and Dular (UV sensitive), were exposed to natural and enhanced ultraviolet-B (UV-B) irradiation for 1, 7, and 14 days, and two-dimensional gel electrophoresis in combination with mass spectrometry (MS) and bioinformatics were used to compare the different proteomic responses in the leaves of the two cultivars. Thirty-nine proteins were up- or downregulated following the UV-B treatments. Among them, 30 increased or decreased more than 1.5-fold in abundance. They were further tested by using matrix-assisted laser desorption/ionization time of flight MS and performed a database search. Twentyfour proteins were thus identified. These identified proteins were mostly upregulated in Lemont, whereas only 14 of them upregulated in Dular. Nine proteins involved in glycometabolism and fatty acid metabolisms, signal transduction, and protein synthesis and folding in Dular were not changed. These results suggest that there was a complex regulative mechanism on the proteomes in rice leaves upon UV-B exposure.

Building Change Detection Using Deep Learning for Remote Sensing Images

Chang Wang,Shijing Han,Wen Zhang,Shufeng Miao 한국정보처리학회 2022 Journal of information processing systems Vol.18 No.4

To increase building change recognition accuracy, we present a deep learning-based building change detection using remote sensing images. In the proposed approach, by merging pixel-level and object-level information of multitemporal remote sensing images, we create the difference image (DI), and the frequency-domain significance technique is used to generate the DI saliency map. The fuzzy C-means clustering technique preclassifies the coarse change detection map by defining the DI saliency map threshold. We then extract the neighborhood features of the unchanged pixels and the changed (buildings) from pixel-level and object-level feature images, which are then used as valid deep neural network (DNN) training samples. The trained DNNs are then utilized to identify changes in DI. The suggested strategy was evaluated and compared to current detection methods using two datasets. The results suggest that our proposed technique can detect more building change information and improve change detection accuracy.
