CNN's technologies that represent emotional detection include primitive CNN algorithms, deployment normalization, and drop-off. We present the methods and data of the three experiments in this paper. The training database and the test database are set up differently. The first experiment is to extract emotions using Batch Normalization, which complemented the shortcomings of distribution. The second experiment is to extract emotions using Dropout, which is used for rapid computation. The third experiment uses CNN using convolution and maxpooling. All three results show a low detection rate, To supplement these problems, We will develop a deep learning algorithm using feature extraction method specialized in image processing field.

Skin detection in computer vision is used in various fields. Many studies have been conducted to detect skin. We studied skin detection in three ways. The first is that the range of YCbCr is allocated separately. The second is the application of the MLPs model. The last is the application of the GCN model. MLPs are chosen as the best model on the SFA dataset. However, in general images, GCN has overwhelmingly good results. This is because information acquisition of surrounding pixels exists.
濟州道 玄武岩 碎石組骨材를 使用한 콘크리트의 强度에 관한 實驗的 硏究

There are many factors to influence on the physical properties of the concrete, such as the size and shape of aggregates, W/C ratio and the strength of cement, etc. Cheju island is regionally volcanic island. The coarse aggregates to be generally utilized for producing the concrete in Cheju island are the crushed ones of basalt. However, the aggregates are locally different chemical and physical properties and these differences show different properties of concrete. In this study, we investigated the properties of concrete by the utilization of crushed aggregates from two places, Sangchang and Sangga in Cheju island through the test of compressive, tensile, and flexural strength with curing time.
