Purpose: Triage in the emergency departmen (ED) is the preliminary clinical sorting process before full disclosure of patients' problems so that patients with the highest acuity are treated first in the setting of resource constraints. To overcome the inter-rater variability of existing triage tools, the Emergency Severity Index(ESI) was developed and was shown to be both valid and reliable in practice. Because of the disparity in practice patterns and some inappropriate criteria in the original ESI, the authors have modified the ESI and determined its inter-rater reliability. Methods: We applied the modified ESI to a convenient sample of adults who visited an urban academic ED between July 24, 2001, and August 5, 2001. After completion of a short, 4-hour training course on the modified ESI, an intern and emergency medicine resident pair triaged the patients independently. The inter-rater reliability was measured using a weighted kappa analysis and was categorized as excellent( 0.8),good (0.60-0.79),or fair( 0.59). Results: Five hundred forty-two patients were enrolled. The overall weighted kappa between the intern and the resident was 0.82 (95% Cl : 0.78-0.86). Among the 542 patients, 469/542 (87%), pairs agreed exactly, 67(12%) pairs disagreed by 1 level, and 6 (1%) pairs by 2 levels. Conclusion: In this study, the modified ESI demonstrated excellent inter-rater reliability when used by residents and interns for our ED patients.

Purpose: The objective of this study was to develop a new nomogram that can predict 28-day mortality in severe sepsis and/or septic shock patients using a combination of several biomarkers that are inexpensive and readily available in most emergency departments, with and without scoring systems. Materials and Methods: We enrolled 561 patients who were admitted to an emergency department (ED) and received early goal-directed therapy for severe sepsis or septic shock. We collected demographic data, initial vital signs, and laboratory data sampled at the time of ED admission. Patients were randomly assigned to a training set or validation set. For the training set, we generated models using independent variables associated with 28-day mortality by multivariate analysis, and developed a new nomogram for the prediction of 28-day mortality. Thereafter, the diagnostic accuracy of the nomogram was tested using the validation set. Results: The prediction model that included albumin, base excess, and respiratory rate demonstrated the largest area under the receiver operating characteristic curve (AUC) value of 0.8173 [95% confidence interval (CI), 0.7605–0.8741]. The logistic analysis revealed that a conventional scoring system was not associated with 28-day mortality. In the validation set, the discrimination of a newly developed nomogram was also good, with an AUC value of 0.7537 (95% CI, 0.6563–0.8512). Conclusion: Our new nomogram is valuable in predicting the 28-day mortality of patients with severe sepsis and/or septic shock in the emergency department. Moreover, our readily available nomogram is superior to conventional scoring systems in predictingmortality.

Evolution Programs, a form of Genetic Algorithms transformed from chromosome representation, are applied to the Timetabling of University which is one of the NP-hard problems. At the step of algorithms application, each class is established to be a specific category in feasible solution space. At. the same time, the exiting gene used in chromosome expression of Evolution Programs is modified to satisfy constraints effectively by transformation of gene which has multi-information. The new crossover method for fester operation in the Recombination attempted.. Roulette wheel selection and tournament selection are prepared.

Housing policies of the government have been developed while sensitive to fluctuations in house prices has played great axis of economic policy in each era. However, housing policy that corresponds to the situation of the market, will lose the public s trust is the consumer of real estate, housing policy, began to lose the adjustment function of the market. Therefore, in the present study is to study the relevances of housing policy to changes in house prices and the economy, it tries to present the direction of the future of housing policy. Housing policy up to now, it is not a long-term measures, rather than the policies that have been formulated to have what goal as short-term measures, with a symptomatic nature to try to correct only the current situation is and has been analyzed and, the housing policy has revealed that the influence of fluctuations in housing prices and economy. It was possible to derive the two conclusions based on the above analysis results. First, government intervention market failure, if the effect is low, will be without intervention except for the minimum parts. Effect of housing policy, for impact on housing prices is not large, it was seen that the market housing market on the degree of constraint to properly implement the role can be normal. Secondly, if currently actively intervene in the market as, so far policy new paradigm of policies that are differentiated and of will need to establish been developed. There are differences of both methods, but to restore public confidence, it should be considered both for normalization of market function.

The city has residential, commercial, and industrial features that is certain of the areas that have a certain personality. Among these, commercial is get a economic benefits to each other while social exchanges through the contact. Where traffic is often of the people of the city, a growing number of opportunities for natural contact, this naturally leads to an increase in commercial activity. Commercial activity that started on the street, evolved in the form of a physical space, such as stalls and shops with a certain amount of equipment, with the area, such as the market of the mall crowded shops of various industries to form a city tade area. As society changes, the shops in the city have a wide range of industries repeated generations and disappearances and the symptoms were similar industries are clustered by type and size of the commercial city. The specialized street, refers to the street that is carried out regional differentiation of the commercial area in the urban commercial industries of the same or similar functions located out the congestion at a certain place in order to create economies of agglomeration. However Daejeon city assign and operate the specialized streets of three districts(Dong-gu, Daeduk-gu, Jung-gu) but most of specialized streets are not operate properly. Especially Mok-dong· Jungchon-dong custom fashion street naturally formed with materials shop, sub-materials shop , tailor shop since 1970. It is a spontaneous crowded with historical meaning. But Mok-dong· Jungchon-dong custom fashion street having various difficulties in spite of the historical and cultural values, that it is necessary to strive for activation can do. In this study, focus on Mok-dong·Jungchon-dong custom fashion street of specialized streets in Dajeon and provide a policy issue for sustainable development.
