The purpose of this study is to perform the effectively advanced airway management in an emergency patient with cardiac arrest and trauma by comparing the appearance of influence in a change of visual-field height upon endotracheal intubation according to a change in position with intubation of paramedics in a moving ambulance and by analyzing the appearance of the influence in a patient's change in position with intubation upon speed in endotracheal intubation. Research subjects were randomly extracted 60(30 people for control group, 30 people for experimental group) people as the paramedics who are working at 13 fire stations in C Province. Data analysis was carried out ${\chi}^2$-test, independent t-test, paired t-test by using SPSS WIN 14.0 Version. As a result of research, to improve speed of the advanced airway management, it is considered to be likely effective in a patient's sniffing position and in the endotracheal intubation in the upper space of the main stretcher. The self-confidence in intubation after experiment increased significantly. Thus, the continuous education(training) on the intubation position and method within ambulance is considered to be likely needed for improving efficiency of the advanced airway management.

The purpose of this study is to suggest the basic data for lowering cyber university students' dropout rate and fostering continuous learning environment through understanding that cyber university student's private variance, an education institute variance and social variance have the impact on a student's determining dropout. For this, we selected students in A cyber university and carried out surveys for 500 students from April first to May 31st, 2009 using convenience sampling. We excluded answers whose results are considered to be insufficient or overlapped among answers of 336 students and used 304 answers in this study. We carried out logistics regression analysis using SPSS for Winow 15.0 for data analysis. First, it proved that individual interest variance affects the dropout. Second, it turned out that educational institute's environment variance has impact on the dropout. Third, it proved that social environment factor affects the dropout. Fourth, only individual variance among individual, an educational institute and social variance has meaningful impact on the dropout in terms of statistics.

The purpose of this study is to analyze, medical institutions wanted to investigate what caused the shortage of opticians' manpower and suggest solutions. This study was conducted on 31 opticians (11 male and 20 female) working at medical institutions through a self-reporting method survey. Through the survey, basic information of the subjects and the information and satisfaction level of the medical institution on duty were investigated and analyzed. There were many people who had a license for optometrist but did not do optometrist work, and the married people were less satisfied with their work and the proportion of people who did not do optometrist work was higher. The cause of these problems was salary. Opticians who needed higher salaries for marriage and other reasons were able to increase their salaries by adding other tasks in their own areas. This unsatisfactory salary at medical institutions has led to a shortage of optometrists at ophthalmic clinics.

Tracheal stenosis in children are often the result of prolonged intubation and its treatment depends on the severity and extent of the involved segment. Repeated surgical endoscopic procedures may be indicated in those with mild stenoses mainly consisting of granulation tissues, However, surgical reconstruction of the airway should be performed in patients with severe, extensive stenoses composed of mature scar tissue. The senior author has successfully managed such patients with cartilage graft augmentation and tracheal resection anastomosis. This is a presentation of 9 pediatric patients with tracheal stenosis who have been successfully treated by resection anastomosis. The details of the cases and indications for this type of surgery are discussed.

The purpose of this study was to develop a multicultural education practice scale for preschool teachers and to examine the reliability and validity of the scale. Participants for this study were 310 preschool teachers from Seoul and Gyeonggi. The multicultural education practice scale for preschool teachers was consisted of 3 factors, 'multicultural national to understand', 'interactions with multicultural children' and 'multicultural culturally to understand' with 13 items. Cronbach's ${\alpha}$ was ranged from .74 to .82. The confirmatory factor analysis revealed that RMSEA=.08, SRMR=.06, NNF=.90, and CFI=.92. All these results show that the multicultural education practice scale for preschool teachers is quite reliable and valid.

It was found to have hacking attempts totaling 115,000 to target the public sector since 2011 to 2015. National Intelligence Service was conducting survey information security management states of a wide range of national-public institutions up to 800 including government agencies in the 2012, while instructing to complement shortcomings. However, there is still going to occur invasions, such as Korea Hydro & Nuclear Power hacking. Even though KHNP's security personnel was only 53 people, in the total 20,000 workforces, got the almost perfect score in the 2013 and 2014 related to information security personnel. Through them, we can confirm that between the organizational response to information security incidents and something theoretical is very far. In this paper, we suggest solutions not using the professional staff management but the non-professional staff management to upgrade the level of public agencies information security.

Named entity recognition (NER) seeks to locate and classify named entities in text into pre-defined categories such as names of persons, organizations, locations, expressions of times, etc. Recently, many state-of-the-art NER systems have been implemented with bidirectional LSTM CRFs. Deep learning models based on long short-term memory (LSTM) generally depend on word representations as input. In this paper, we propose an approach to expand word representation by using pre-trained word embedding, part of speech (POS) tag embedding, syllable embedding and named entity dictionary feature vectors. Our experiments show that the proposed approach creates useful word representations as an input of bidirectional LSTM CRFs. Our final presentation shows its efficacy to be 8.05%p higher than baseline NERs with only the pre-trained word embedding vector.

Named Entity Recognition is a system that extracts entity names such as Persons(PS), Locations(LC), and Organizations(OG) that can have a unique meaning from a document and determines the categories of extracted entity names. Recently, Bi-LSTM-CRF, which is a combination of CRF using the transition probability between output data from LSTM-based Bi-LSTM model considering forward and backward directions of input data, showed excellent performance in the study of object name recognition using deep-learning, and it has a good performance on the efficient embedding vector creation by character and word unit and the model using CNN and LSTM. In this research, we describe the Bi-LSTM-CNN-CRF model that enhances the features of the Korean named entity recognition system and propose a method for constructing the traditional culture corpus. We also present the results of learning the constructed corpus with the feature augmentation model for the recognition of Korean object names.

Backgrounds: To investigate the role of CT as a screening tool and to compare the diagnostic accuracy with that of the fiberoptic bronchoscopy (FOB) in evaluating the causes of hemoptysis. Methods: The retrospective review of plain chest radiograph, CT and FOB was done in 72 patients with hemoptysis. The diagnosis were confirmed by histology (n=33), bacterial culture (n=6), cytology (n=3), serology (n=2), skin test (n= 1), clinical response (n=5), and airway disease mainly by HRCT (n=22). Results: The causes of hemoptysis were shown to be lung cancer (n=29), bronchiectasis (n=19), tuberculosis (n=12), aspergilloma (n=5), invasive aspergillosis (n=l), COPD (n=3) and others (n=3). The sensitivity was 100% and 91,7% by CT and FOB respectively. The diagnostic compatibility was 95.8% and 59.7% by CT and FOB respectively. The diagnostic compatibility in cases with central airway disease was 96.3% and 100 % in CT and FOB. In parenchymal disease, CT and FOB showed 91.3 % and 43.5 % of compatibility, respectively. airway disease, CT and FOB showed 100% and 31.8% compatibility, respectively. That is to say, CT has higher sensitivity and diagnostic compatibility than FOB for identifying the causes of hemoptysis, and is more helpful for patients with hemoptysis from parenchymal or airway disease. FOB had the advantage in obtaining histologic, cytologic and bacteriologic diagnosis with biopsy or washing Conclusion: CT should be used as the screening method before performing FOB for patients with hemoptysis who have normal or nonspecific findings or peripheral airway disease in plain chest radiograph.
