For the purpose of predicting credit card customer churn accurately through data analysis Detecting and tracking objects in continuous video is essential in self-driving cars, security and surveillance systems, sports analytics, medical image processing, and more. Correlation tracking methods such as Normalized Cross Correlation(NCC) and Sum of Absolute Differences(SAD) are used as an effective way to measure the similarity between two images. NCC, a representative correlation tracking method, has been useful in real-time environments because it is relatively simple to compute and effective. However, correlation tracking methods are sensitive to rotation and size changes of objects, making them difficult to apply to real-time changing videos. To overcome these limitations, this paper proposes an object tracking method using the Histogram of Oriented Gradients(HOG) feature to effectively obtain object data and the Convolution Neural Network(CNN) algorithm. By using the two algorithms, the shape and structure of the object can be effectively represented and learned, resulting in more reliable and accurate object tracking. In this paper, the performance of the proposed method is verified through experiments and its superiority is demonstrated.

An Antenna & RF system for a fly-away satcom terminal application on ka-band is presented in this paper. The Fly-away satellite terminal can be moved and operated by two person and adapt automatic satellite tracking system in order to decrease the tracking time. Additionally, for low-power consumption, compact size and light-weight, a dual reflector antenna is constructed using dual-offset gregorian antenna structure. For minimize weight, the reflector of the antenna is made of Magnesium. For low-power consumption and light-weight, the pHEMT MMIC compound devices is utilized. The Electronic Band-Gap(EBG) Low-Pass Filter(LPF) is designed for harmonic rejection. In the receiving part, Low-Noise Block converter(LNB) structure is designed for compact and lightweight. In this paper, fly-away satcom terminal with low-power consumption, compact size and light-weight is described with antenna system and RF system performances. Through the experimentation, fly-away terminal's EIRP is more than 50dBW, G/T is more than $17dB/^{\circ}K$.

Design of Prototype-Based Emotion Recognizer Using Physiological Signals

박병준,정명애,장은혜,김상협 한국전자통신연구원 2013 ETRI Journal Vol.35 No.5

This study is related to the acquisition of physiological signals of human emotions and the recognition of human emotions using such physiological signals. To acquire physiological signals, seven emotions are evoked through stimuli. Regarding the induced emotions, the results of skin temperature, photoplethysmography, electrodermal activity, and an electrocardiogram are recorded and analyzed as physiological signals. The suitability and effectiveness of the stimuli are evaluated by the subjects themselves. To address the problem of the emotions not being recognized, we introduce a methodology for a recognizer using prototype-based learning and particle swarm optimization (PSO). The design involves two main phases: i) PSO selects the P% of the patterns to be treated as prototypes of the seven emotions; ii) PSO is instrumental in the formation of the core set of features. The experiments show that a suitable selection of prototypes and a substantial reduction of the feature space can be accomplished, and the recognizer formed in this manner is characterized by high recognition accuracy for the seven emotions using physiological signals.

Modeling of a Nanofilter and Its Application to the Separation of DNA

박병준 한국물리학회 2018 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.72 No.2

We consider a nanofilter device that has been used experimentally for separation of DNA (Deoxyribonucleic acid) with different lengths less than thousands of base pairs. We introduce a master equation for describing the dynamics of DNA in a nanofilter under an external electric field, and obtain the probability distribution of DNA for a given nanofilter geometry. Our results are consistent with experimental results and provide an estimate of the minimum device size required to obtain the target separation resolution in the separation of DNA.

심장이식 수혜자의 사회적지지, 우울 및 건강상태

박병준,신나미,Park, Byung-Jun,Shin, Nah-Mee 한국중환자간호학회 2014 중환자간호학회지 Vol.7 No.1

Purpose: As the number of cases of heart transplantation (HT) and the survival rate have increased, concerns regarding post-HT life have grown. This study was conducted to explore the relationships of perceived social support to the depression and health status of HT recipients. Methods: This descriptive study targeted all recipients who had undergone HT at S University Hospital since 1994, and 32 recipients were recruited. Results: 90.6% of the recipients were men, and the average age at the time of surgery was $47.4{\pm}13.4$ years. The ejection fraction was increased from $18.47{\pm}5.63%$ to $63.25{\pm}7.57%$, and 31 cases of New York Heart Association (NYHA) class III and IV improved to class I or II after HT. The patients reported mild depression even with high perceived social support and improved health status after HT. Among those resource persons who offered support, they reported their spouse, doctors, and nurses as most meaningful to them. Conclusion: This study confirmed the positive effects of HT on the recipients' physical improvement. It also added the discovery that the importance of recipients' subjective perception of social support might be critical for their more successful recovery and adjustment to post-HT life. Focusing on a different approach to social support and types of social resources in the recovery phase is suggested for future studies on quality of life after HT.

Analysis of Physiological Responses and Use of Fuzzy Information Granulation–Based Neural Network for Recognition of Three Emotions

박병준,장은혜,김경호,김상협 한국전자통신연구원 2015 ETRI Journal Vol.37 No.6

In this study, we investigate the relationship between emotions and the physiological responses, with emotion recognition, using the proposed fuzzy information granulation–based neural network (FIGNN) for boredom, pain, and surprise emotions. For an analysis of the physiological responses, three emotions are induced through emotional stimuli, and the physiological signals are obtained from the evoked emotions. To recognize the emotions, we design an FIGNN recognizer and deal with the feature selection through an analysis of the physiological signals. The proposed method is accomplished in premise, consequence, and aggregation design phases. The premise phase takes information granulation using fuzzy c-means clustering, the consequence phase adopts a polynomial function, and the aggregation phase resorts to a general fuzzy inference. Experiments show that a suitable methodology and a substantial reduction of the feature space can be accomplished, and that the proposed FIGNN has a high recognition accuracy for the three emotions using physiological signals.
