Purpose: Resuscitation rooms in emergency department are places for time-critical tasks. This study aimed 1) to develop a resuscitation protocol for dyspneic patients and 2) to evaluate the effect of the resuscitation protocol for dyspneic patients in improving clinical performances. Methods: A panel of experts including emergency physicians and nurses developed a resuscitation protocol for dyspneic patients which included a list of critical interventions and time-limits. The resuscitation protocol was implemented in a emergency medical center for two months. Clinical performances of health care providers were compared by analyzing video-recorded clinical performances. Results: The resuscitation protocol consisted of four steps: Initial treatments within 5 minutes, main treatments within 15 minutes, diagnostic tests within 30 minutes, and disposition within 60 minutes. A total of 43 dyspneic patients (23 patients experimental group, 20 patients control group) were included for the analysis of the clinical performance change. Clinical performance rates were improved significantly from control group (66.71%) to experimental group (82.41%) after implementing the resuscitation protocol (Z=-3.09, p=.004). Conclusion: The resuscitation protocol developed for dyspneic patients improved clinical performance rates of health care providers. Further development of clinical protocols for other emergent cases at resuscitation rooms are strongly recommended.

This study was carried out to provide basic data for the development of an educational program by assessing the its effects on the MDROs infection management performances of nurses at general hospitals. Data was obtained through a structured questionnaire survey conducted on 202 nurses. The average of knowledge score was 17.68 and their perceived susceptibility, perceived severity, perceived benefits, and performances had correlation. There was difference in their performances in accordance with their general characteristics including marriage, clinical experiences, positions, and affiliated department. Factors that affected MDROs infection management performance included perceived benefits and affiliated department with an explanation power of 35%. Therefore, it is necessary to emphasize the benefits by including advantages and effects of performing the MDROs infection control at the time of the development. In addition, nurses are required to have MDROs infection control education.

Objective: To investigate the effects of dietary supplementation with different levels and molecular weights of fungal ${\beta}$-glucan on productive performances, health, carcass traits and meat quality in broilers. Methods: Two hundred and ten of one-day-old chicks with equal sex were assigned to seven experimental groups in $2{\times}4$ factorial arrangement. These groups were supplemented with (0, 10, 30, and 60 ppm) of molecular weight 1-3, 1-6 ${\beta}$-glucan (low or high). High molecular weight ${\beta}$-glucan (H: 943 kDa) was obtained from Ophiocordyceps dipterigena BCC 2073, whereas H with ${\gamma}$-Irradiation treatment was performed to achieve low molecular weight ${\beta}$-glucan (L: 8 kDa). Results: There was no statistical significance in productive performances, apparent digestibility and interaction between fixed factors along 42 days of experiment (p>0.05). A higher caecal amylase activity was present in the group that received L, while there was a dramatic decrease in H and the control groups, respectively (p<0.05). The increase of supplemental dose increased caecal amylase activity (p<0.05). Immunomodulatory effects from L was revealed by the marked increase of phagocytic activity, relative weight of thymus and bursa of fabricius (p<0.05). Similarly, the additive dose at 30 ppm provided the same results, whereas the only significant difference with supplementation at 60 ppm was an increase in phagocytic activity (p<0.05). Interestingly, villi height of broilers fed L was higher than other groups (p<0.05). The treatments did not influence haematology, blood chemistry, antibody production level against vaccination, carcass traits and meat quality (p>0.05). Conclusion: The supplementation of L at 30 ppm was suggested to achieve benefits of immune modulation without adverse effects on other parameters.

A study has been carried out on the implementation of IMCA (Linear Moving Voice Coil Actuator) to a flexible robot arm modelled as cantilever beam. Control performances are evaluated by computer simulation and theoretical analysis is validated by experiments. From this study, it is proved that the LMVCA can be applied easily to the control system and suppress vibration effectively.

The advent of deep learning-based algorithms has facilitated researches on target detection from synthetic aperture radar(SAR) imagery. While most of them concentrate on detection tasks for ships with open SAR ship datasets and for aircraft from SAR scenes of airports, there is relatively scarce researches on the detection of SAR ground vehicle targets where several adverse factors such as high false alarm rates, low signal-to-clutter ratios, and multiple targets in close proximity are predicted to degrade the performances. In this paper, a dataset of ground vehicle targets acquired from TerraSAR-X(TSX) satellite SAR images is presented. Then, both detection and instance segmentation are simultaneously carried out on this dataset based on the deep learning-based Mask R-CNN. Finally, this paper shows the future research directions to further improve the performances of detecting the SAR ground vehicle targets.

This study describes the jump error smoothing scheme with fuzzy logic based on the scalar adaptive filter. The scalar adaptive filter is an useful algorithm for smoothing abrupt jump errors. However, the performances of scalar adaptive algorithm depend on the variance of real signal. So to design an effective algorithm, many informations of real and jump signal are required. In this paper, the fuzzy rules are designed by the analysis of scalar adaptive filter, and then the improved and simplified scheme is developed for smoothing the jump error. Simulations to INS/GPS integrated system show that the proposed method is effective.

In this paper, the copy mechanism and input feeding are applied to recurrent neural network(RNN)-search model in a Korean-document summarization in an end-to-end manner. In addition, the performances of the document summarizations are compared according to the model and the tokenization format; accordingly, the syllable-unit, morpheme-unit, and hybrid-unit tokenization formats are compared. For the experiments, Internet newspaper articles were collected to construct a Korean-document summary data set (train set: 30291 documents; development set: 3786 documents; test set: 3705 documents). When the format was tokenized as the morpheme-unit, the models with the input feeding and the copy mechanism showed the highest performances of ROUGE-1 35.92, ROUGE-2 15.37, and ROUGE-L 29.45.

Recently, the SAR-GMTI mode is becoming increasingly essential in airborne radar systems. While SAR requires wideband waveforms for high resolution imaging, GMTI requires narrowband waveforms for doppler processing, which makes general LFM waveforms difficult to use for SAR-GMTI. This paper analyses the FJB(Frequency Jump Burst) waveform, which is studied for the SAR-GMTI waveform, and presents the method for the pulse compression and SAR image formation using FJB waveforms. Simulation results show that there is little difference in performances between the FJB waveform and the LFM waveform.
