This paper proposes a miniaturized high-isolation diversity antenna for wearable wireless body area network (WBAN) applications. An inverted-F type radiating element is used to reduce the overall dimension of the proposed antenna to $30mm{\times}30mm{\times}2.5mm$. The antenna performance on the human body phantom is analyzed through simulation and the performance of the fabricated antenna is verified by comparing the measured data with that of the simulation when the antenna is placed on a semi-solid flat phantom with equivalent electrical properties of a human body. The fabricated antenna has a 10 dB return loss bandwidth over the Industrial Scientific Medical (ISM) band from 2.35 GHz to 2.71 GHz and isolation is higher than 28 dB at 2.45 GHz. The measured peak gain of antenna elements # 1 and # 2 is -0.43 dBi and -0.54 dBi, respectively. Performance parameters are analyzed, including envelope correlation coefficient (ECC), mean effective gain (MEG), and the MEG ratio. In addition, the specific absorption ratio (SAR) distributions of the proposed antenna are measured for consideration in use.

The purpose of this study was to examine the psychometric property of the Children's Behavior Questionnaire(CBQ), including reliability, content validity, construct validity, cross validity, and concurrent validity with EAS(Emotionality, Activity, Sociability) scale. The CBQ is a caregiver report measure designed to provide a detailed assessment of temperament in children 3 to 7 years of age. In this study, two groups of participants were included to check cross validity. The first group of participants were 108 preschoolers, 3 to 7 years of age attending kindergartens or child care centers, and their mothers. The second group of participants were 168 preschoolers and their mothers. The CBQ subscales demonstrate adequate internal consistencies. Also, exploratory and confirmatory factor analyses of the CBQ scale reliably recover a three-factor solution indicating three broad dimension of temperament: extraversion/surgency, negative affectivity, and effortful control. Evidence for concurrent validity derives from results of correlation analysis with EAS scale.

R.W.B. Lewis called Greene's three novels - Brighton Rock, The Power and the Glory and The Heart of the Matter - Greene's 'trilogy'. Greene was paid full attention by many readers and many critics after publishing these Catholic novels. The themes and plots of his Catholic novels are unique and beyond those of traditional Catholicism. Greene is always willing to stand on the edge of reality. He always conflicts with the reality and eagerly searches for a higher, more spiritual dimension. If we view Greene's protagonists from an open-minded viewpoint, Pinkie of Brighton Rock will be saved at the mercy and grace of God in spite of being evil. Whiskey Priest of The Power and the Glory is worthy of being called a saint in spite of his drunkenness and adultery. Scobie of The Heart of the Matter will be within God's grace in spite of his suicide. The reason all protagonists are saint-like is clear and simple because they all have faith and sacrifice themselves to obey God's first commandment, to love others. To summarize the theme of Greene's 'trilogy', we can say that love is the most valuable in the world. God has mercy for all human beings. The protagonists love God and they love others. In fact, Greene's faith is found in his love of human beings and God.

In this paper, for recognize a night pedestrian from an infrared video, a new method differentiated from the existing feature vector is proposed and experimented. The new approach focuses on the shape feature vector of the structure and shape of the pedestrian image divided by the human body seven split ratio. The pedestrian images are divided into 7 square blocks from the still image of the preprocessing process. And to reduce the dimension, the square block is converted into a mosaic block. The scalar and direction of the shape feature vector is calculated by the brightness and position of the element in the mosaic. For practicality of infrared video system, the proposed method simplifies the data to be processed by reducing the amount of data in the preprocessing in order to continuously batch process the entire system in real time. Through the experiments, we verified the validity of the proposed shape feature vector. In comparison to the existing method, we propose a new shape feature vector generation method as the feature vector for night pedestrian recognition.

This study evaluated several known echocardiographic markers related to the assessment of severity in dogs with patent ductus arteriosus (PDA) after the closure of ductus arteriosus (DA). Forty-two dogs with patent ductus arteriosus were enrolled in this study. Evaluated echocardiographic markers were left atrial to aortic root ratio, left ventricular end-diastolic dimension to aortic root ratio, indexed left ventricular end-diastolic and end-systolic dimensions, end-diastolic and end systolic volume index, pulmonic flow to systemic flow (Qp/Qs) ratio, velocities of pulmonary regurgitant and systolic jets, pulmonary flow profiles and the presence of mitral regurgitation. Those markers were evaluated before, 1 day, and 30 days after the closure of DA. Statistically significant changes in some echocardiographic markers (i.e., Qp/Qs) were observed. Although several studies in human and dogs have evaluated the clinical outcome of PDA occlusion using several echocardiographic markers, this study has firstly evaluated all echocardiographic markers known to be useful for assessing the clinical outcome of PDA occlusion in human, and has demonstrated that those markers including the Qp/Qs and pulmonary flow profiles were useful in evaluating of clinical outcome of PDA in dogs and the reduction of LA and LV preload after ductal closure could dramatically reduce after successful ductal occlusion of PDA in dogs.

It is interesting that the costume in the period of romanticism was very fantastic and peculiar in its aspects. The romanticism in the fashion theme of these days' mode represents the image of this France romanticism. Costume has unseparable relations with the style of art in the same period. Especially, plastic art has logical connection with costume because it is an art through silhouette, line, color and texture felt by visional and solid feelings. This kind of study is important in order to understand the fashion of today, to anticipate the fashion in future and to get recognition of costume as a genre of arts. This study is to analyse and compare the general features in the grown-ups' everyday clothes of France from 1815 to 1850 when costume in the period of romanticism reached its peaks with the art of architecture, paintings, sculpture and technology, with the aid of documentary recordings. The above study explain that costume is expressed by the same plastic art of the period if it coexists in the same cultural background. Finally, we can plan the costume in future on an artistic dimension by understanding correctly the characteristics of plastic art which modern costume pursue from an artistic point of view.
