  • Purpose: Nursing protocols for glucose management are well known for both healthy term newborns and high-risk newborns. However, for less risky newborns who are under only observation surveillance, hypoglycemia could be overlooked unless clinical symptoms develop. Methods: A retrospective study was performed to explore factors influencing variations in glucose levels in 91 newborns who did not require any interventions, but were under nursing surveillance, at a level II neonatal intensive care unit. Data were retrieved from electrical medical records on glucose levels, demographic characteristics, and other clinical characteristics of newborns in their first day of life from January 2016 to May 2019. Results: Glucose levels tended to stabilize within the normal range (60~80 mg/dL) as time passed during the first day of life. Cesarean section, multiple gestation, abnormal growth, and later preterm birth were associated with low glucose levels in the first 2 hours of life. Thirty-one newborns experienced a hypoglycemic episode (< 45 mg/dL) during the first 24 hours of life. Conclusion: The findings of this study support the active encouragement of early feeding within 2 hours of birth and urgent adoption of a structural protocol for glucose surveillance in newborns with potential health problems immediately after birth.

  • Interest about social security has recently increased in favor of safety for infrastructure. In addition, advances in computer vision and pattern recognition research are leading to video-based surveillance systems with improved scene analysis capabilities. However, such video surveillance systems, which are controlled by human operators, cannot actively cope with dynamic and anomalous events, such as having an invader in the corporate, commercial, or public sectors. For this reason, intelligent surveillance systems are increasingly needed to provide active social security services. In this study, we propose a core technique for intelligent surveillance system that is based on swarm robot technology. We present techniques for invader enclosing using swarm robots based on multiple distributed object environment. The proposed methods are composed of three main stages: location estimation of the object, specified object tracking, and decision of the cooperative behavior of the swarm robots. By using particle filter, object tracking and location estimation procedures are performed and a specified enclosing point for the swarm robots is located on the interactive positions in their coordinate system. Furthermore, the cooperative behaviors of the swarm robots are determined via the result of path navigation based on the combination of potential field and wall-following methods. The results of each stage are combined into the swarm robot-based invader-enclosing technique on multiple distributed object environments. Finally, several simulation results are provided to further discuss and verify the accuracy and effectiveness of the proposed techniques.

  • It is helpful to use Intelligent Video Surveillance to replace and supplement the demerit which can possibly occur due to the mistake that can be made by human management. To accomplish this, it is essential that the system should digitalize image information from surveillance camera so that the system, itself, can be able to locate a object and to analyze the pattern of the object. Also, it is imperative that the system should have ability to operate a alarm and a entrance blocking system and to notify a situation to a security manager. Zooming a small object form a screen, however, requires a exact zooming ratio of the object and a shift of centric coordinate. In this paper, It is able to locate and observe closely a object from flexible background, regardless of the distance, by calculating a zooming ratio according to object moment, pan coordinate, and tilt coordinate.

  • The aim of the present study was to investigate whether Bovine Spongiform Encephalopathy (BSE) is present in this country and to analyze the Global BSE Risk (GBR) status in Bangladesh. A total of 2,000 brain samples were collected from cattle older than 30 months of age, slaughtered for human consumption in the district slaughter houses from 2005 to 2006. The brainstem (obex), Pyriform lobe, cerebrum and cerebellum were subjected to histopathological study. Samples that showed some nonspecific lesions were subjected to immunohistochemistry and only brain stem to ELISA for the detection of abnormal prion protein $PrP^{sc}$. In passive surveillance, annual overall diseases of cattle, buffalo, sheep and goats in Bangladesh were collected from Department of Livestock Services (DLS), Dhaka to investigate the occurrences of neurological diseases. Import related data were collected from "National Export Promotion Bureau" Kawran Bazar, Bangladesh Bank and DLS to analyze the importing products of animal origin (cattle, buffalo, sheep and goats) from different countries to find whether or not the imported products posed any risk for the BSE. In an actire surveillance conducted in slaughter house, histopathologically BSE specific lesions were not detected in any of the brain samples, but other nonspecific lesions were observed. No $PrP^{sc}$ was detected from the samples by immunohistochemistry and ELISA. DLS report also supported the absence of BSE in cattle and buffalo and scrapie in sheep and goats in Bangladesh. It was also clearly recorded that Bangladesh imported livestock products from countries in GBR level I and II but not from countries in GBR level III and IV. From this study it apparently seems that BSE is not currently present in the indigenous animals in Bangladesh and poses no or negligible risk to human and animal health.

  • Moving Object segmentation extracts an interested moving object on a consecutive image frames, and has been used for factory automation, autonomous navigation, video surveillance, and VOP(Video Object Plane) detection in a MPEG-4 method. This paper proposes new segmentation method using difference images are calculated with three consecutive input image frames, and used to calculate both coarse object area(AI) and it's movement area(OI). An AI is extracted by removing background using background area projection(BAP). Missing parts in the AI is recovered with help of the OI. Boundary information of the OI confines missing parts of the object and gives inital curves for active contour optimization. The optimized contours in addition to the AI make the boundaries of the moving object. Experimental results of a fast moving object on a complex background scene are included.

  • In this paper, we propose a panorama-based object tracking scheme for wide-view surveillance systems that can detect and track moving objects with a pan-tilt camera. A dynamic mosaic of the background is progressively integrated in a single image using the camera motion information. For the camera motion estimation, we calculate affine motion parameters for each frame sequentially with respect to its previous frame. The camera motion is robustly estimated on the background by discriminating between background and foreground regions. The modified block-based motion estimation is used to separate the background region. Each moving object is segmented by image subtraction from the mosaic background. The proposed tracking system has demonstrated good performance for several test video sequences.

  • African swine fever (ASF) is one of the most complex infectious swine diseases and the greatest concern to the pig industry owing to its high mortality and no effective vaccines available to prevent the disease. Since the first outbreak of ASF in pig farms, ASF has been identified in 14 pig farms in four cities/counties in South Korea. The outbreak was resolved in a short period because of the immediate control measures and cooperative efforts. This paper reviews the ASF outbreak and the experience of successfully stopping ASF in pig farms in South Korea through active responses to prevent the spread of ASF. In addition, suitable changes to build a sustainable pig production system and collaborative efforts to overcome the dangerous animal disease, such as ASF, are discussed.

  • Objective: The rising number of carbapenemase-resistant Enterobacteriaceae (CRE) cases has become a concern worldwidely. This study investigated patient characteristics with CRE and analyzed the risk factors associated with its acquisition. Methods: A retrospective review of the electronic medical records of the Kangbuk Samsung Medical Center from May 2016 to April 2019 was performed. The inclusion criterion was hospitalized patients aged ≥18 years with confirmed CRE acquisition. Patients were divided by CRE acquired and non-required patients. CRE acquired patients were those with CRE confirmed by their active surveillance cultures, while non-acquired patients were those with carbapenemase-sensitive Enterobacteriaceae (CSE). If CRE was isolated more than once during hospitalization, only the first isolation was used for data analysis. Patient characteristics, antibiotic used, and the duration of use were compared between two groups using univariate analysis, and the risk factors associated with CRE were analyzed using multiple logistic regression analysis. Results: Among the 73 CRE acquired patients, 44 (60.3%) were positive for carbapenemase-producing Enterobacteriaceae (CPE). Infection from Klebsiella pneumonia (42 cases, 57.5%), Escherichia coli (17 cases, 23.3%), and Enterobacter cloacae (5 cases, 6.8%). The risk of CRE acquisition was significantly increased by 4.99 times [confidence interval (CI), 1.40-17.78; p=0.013] with mechanical ventilation, 3.86 times (CI, 1.59-9.36; p=0.003) with penicillin administration, and 21.19 times (CI, 6.53-68.70; p<0.001) with carbapenem administration. Conclusions: Proper antibiotic use including the selection, frequency, and duration, and patients on mechanical ventilators need close monitoring.

  • Opisthorchiasis is a health problem in Thailand particularly in northeast and north regions where have been reported the highest of cholangiocarcinoma. Active surveillance is required, therefore a cross-sectional surveyed was conducted in Nong Bunnak sub-district of Nakhon Ratchasima province, Thailand. A total of 367 participants were selected by multistage sampling from 5 villages located near natural water resources. Participants completed a predesigned questionnaire containing behavior questions regarding liver fluke disease, covering reliability and validity knowledge (Kuder-Richardon-20) = 0.80, attitude and practice (Cronbach's alpha coefficient) = 0.82 and 0.79, respectively. Descriptive statistics included frequencies, percentages, means, and standard deviations. The majority of the participants were female (58.3%), age group between 21-30 years old (42.5%), with primary school education (59.9%), occupation in agriculture (38.1%), and married (80.9%). They had past histories of raw fish consumption (88.3%), stool examination (1.4%), anti-parasite medication used (4.6%). Heads of villages, village health volunteers, television, and village newstations were the main sources for disease information. Participants had a moderate level of behavior regarding liver fluke disease. The mean scored of knowledge regarding liver fluke life cycle, transmission, severities, treatment, prevention and control was 10.9 (SD=0.5), most of them had a moderate level, 95.1%. The mean score for attitude regarding liver fluke prevention and control was 45.7 (SD=9.7), and for practice was 30.6 (SD=10.5). Participants had a moderate level of attitude and practice, 94.5% and 47.7, respectively. This study indicates that health education is required in this community including stool examination for liver fluke as further active surveillance screening.
