In the sintering of YIG, abnormal grain growth phenomena was observed. This abnormal grain growth is related to the sintering temperature in this experiment. In the sintering below 145$0^{\circ}C$., the sintered body showed narrow size distribution. However, in the sintering at 145$0^{\circ}C$, a few grains grew rapidly with respect to other grains, and bimodal size distribution was appeared. Liquid phase was not observed far from the abnormally grown large grains, but only near the large grains. This means that the abnormal grain growth was caused by the nonuniform distribution of liquid phase which promote the grains growth. This nonuniform distribution of liquid phase was thought to be due to the nonuniform mixing of the starting materials. This abnormal grain growth was suppressed by enhance the compositional uniformity by multiple calcination.

The purpose of this study is to report the hemostatic effects of Kungkwikyoae-tang for abnormal uterine bleeding. Kungkwikyoae-tang has been known as a useful herbal medication for uterine bleeding. We treated patients who had been suffering from abnormal uterine bleeding with herb-medication, acupuncture therapy, pharmacopuncture therapy and moxa therapy. We prescribed Kungkwikyoae-tang three times a day. The improvement of symptoms were measured by checking patient bleeding volume, frequency and other physical signs. After Kungkwikyoae-tang was given, abnormal uterine bleeding volume and frequency was reduced and other physical symptoms were improved. This case study shows that Kungkwikyoae-tang has a hemostatic effects against the abnormal uterine bleeding.

The influence of Ti/Sr ratio on abnormal grain growth of Nb-doped SrTiO3 was investigated. For specimens which were isothermally sintered at temperatures above 144$0^{\circ}C$, the nucleation and growth rates of abnormal grain growth were decreased with increasing Ti/Sr ratio. But the onset time of abnormal grain growth was increased with increasing Ti/Sr ratio. The cross-section of abnormally grown grains was mostly hexagonal. When the specimens were quenched in air after they reached their setting temperatures at a heating rate of 3$^{\circ}C$/min, the onset temperature of abnormal grain growth was increased with increasing Ti/Sr ratio and the final grain size was independent of Ti/Sr ratio. The cross-section of abnormally grown grains was mostly rectangular.

In these days abnormal climate occurs frequently because of global warming and earthshock. So it is necessary to prepare for the abnormal conditions like gale, rainfall, heavy snow and high temperature. Fortunately, Korea high speed rail(KTX) have a safety climate detection system for the abnormal weather by using CTC. So the safety is guaranteed in most aspect. But in convention line there isn't any alarm system for the abnormal condition and the train runs until the railroad loss occurred. So convention line need additional regulation same as KTX for the abnormal climate and in the near future passenger safety must be protected by new alarm system.

Abnormal grain growth in alumina was investigated during sinter-HIP process for better understanding of pressure effect on microstructural development. Abnormal grain growth of monolithic alumina was observed near surface region rather than interior region of specimen. Finite element analysis was used to estimate the pressure distribution developed in the specimen. Pressure distribution analysis was in good agreement with grain size distributjion in the specimen. The results of finite element analysis provided that abnormal grain growth monolithic alumina was resulted from the inhomogeneous pressure distribution in the specimen. MgO addition in alumina was effective for the suppression of abnormal grain growth in alumina under inhomogeneous pressure distribution during sinter-HIP process.

Collapse is an abnormal shrinkage resulting in uneven, rough surfaces and/or warping of sawn timber. The maximum abnormal shrinkages of the oak and persimmon specimens were obtained by the quasi-equilibrium drying and were compared with the other drying methods. The effect of steaming and freezing treatments on the shrinkage of wood was also investigated. The Quasi-equilibrium drying used in this study was proved as a good tool to make the maximum abnormal shrinkage of wood. The maximum abnormal volumetric shrinkage possibly caused by collapse could be 16.3% and 14.3% for the oak and persimmon specimens, respectively. In general the steaming-treated specimens shrank less than the controls for the oak specimens, but did more for the persimmon specimens. The volumetric shrinkages of the freezing-treated specimens were more various between the drying methods than those of the control and steaming-treated specimens.

Objectives: This paper aim to report the effects of korean medical treatment including Yikwiseungyang-tang-gagambang on patients with abnormal uterine bleeding. Methods: From 2012 August to 2017 June, six outpatient with abnormal uterine bleeding came to the clinic. The patients took Yikwiseungyang-tang-gagambang and got acupuncture and warm needle therapy. We assessed the patients' bleeding period and bleeding amount. Results: All patients' abnormal uterine bleeding stopped after they took Yikwiseungyang-tang-gagambang in 2~40 days. One patient restart slight bleeding, the bleeding stopped after continual korean medical treatment. Conclusions: Korean medical treatment including Yikwiseungyang-tang-gagambang is effective on patients with abnormal uterine bleeding.

Security control using surveillance cameras is established when people observe all surveillance videos directly. However, this task is labor-intensive and it is difficult to detect all abnormal situations. In this paper, we propose a deep neural network model, called AT-Net, that automatically detects abnormal situations in the surveillance video, and introduces an automatic video surveillance system developed based on this network model. In particular, AT-Net alleviates the ambiguity of existing abnormal situation detection methods by mapping features representing relationships between people and objects in surveillance video to the new tensor structure based on sparse coding. Through experiments on actual surveillance videos, AT-Net achieved an F1-score of about 89%, and improved abnormal situation detection performance by more than 25% compared to existing methods.

Objectives : To examine Korean Medical treatment of abnormal uterine bleeding in classical texts, along with their clinical applicability. Methods : The Benglou chapters in the Donguibogam, Fuqingzhunuke, Xuezhenglun were examined in terms of diagnostic pattern and treatment. Benglou chapters of other medical texts were referenced as well. Basic Korean Medical knowledge of abnormal uterine bleeding and its clinical application were studied. Results : As abnormal uterine bleeding is generally caused by internal damage or deficiency from excessive labor, sexual activity, food, emotional stress, specific causes for each individual should be considered when approaching each case. Conclusions : Korean Medical treatment allows for a tailored approach to each pathology according to age and duration of illness, and has strength in dealing with various situations such as emergency situations, excessive bleeding, blood stagnation. As such, application of Korean Medicine in abnormal uterine bleeding is highly appropriate.

In arrhythmia ECG signal, abnormal beat that has various abnormal shape depending on the generation site and conduction disorders is included and it is very important to diagnose heart disease such as arrhythmia. In this paper, we propose a PVC abnormal beat detection algorithm associated with ventricular disease. The PVC abnormal beat is characterized by distortion of the QRS complex occurs among the components of the ECG signal. Therefore it is possible to detect PVC abnormal beat according to the degree of distortion of the QRS complex. First, quantify the distortion of the QRS complex by using the potential of the R-peak, kurtosis and period. By using the mean and standard deviation, PVC abnormal beat is detected depending on the degree of distortion from the normal beat. The proposed algorithm can detect the average over 98% of the AAMI-V class type abnormal beat associated with ventricular disease in MIT-BIH arrhythmia database.
