As robots are considered one of the mainstream digital transformations, robots with machine vision becomes a main area of study providing the ability to check what robots watch and make decisions based on it. However, it is difficult to find a small object in the image mainly due to the flaw of the most of visual recognition networks. Because visual recognition networks are mostly convolution neural network which usually consider local features. So, we make a model considering not only local feature, but also global feature. In this paper, we propose a detection method of a small marker on the object using deep learning and an algorithm that considers global features by combining Transformer's self-attention technique with a convolutional neural network. We suggest a self-attention model with new definition of Query, Key and Value for model to learn global feature and simplified equation by getting rid of position vector and classification token which cause the model to be heavy and slow. Finally, we show that our model achieves higher mAP than state of the art model YOLOr.

The purpose of this analysis is to investigate the effect of leading characters in picture books on self concept in children. For this study, we selected a total of 55 picture books, all of which were best sellers in four internet book stores. The method used for the study was based on content analysis. The results of this analysis were as follows: First, the gender of leading characters was male more often than female, and the majority of picture books were creative story books and translation books. Second, subordinate parts related to the self-concept were most frequently found in the social self-concept. Social self-concept was positively expressed through the relationship between friend and family characters in story books. Cognitive self-concept was the least. Third, when the frequency of positive and negative expressions in picture books was analyzed, the social self-concept was found to be positively expressed in the subordinate parts of relationships between friends and family. The social self-concept was negatively expressed, however, in the subordinate parts of relationship between non-significant others, and the emotional self-concept was also negatively expressed in the subordinate parts of the emotional recognition and expression. In summary. instances of cognitive self-concept and positive expression were found to be more significant than negative ones.

The purpose of this study was to find out the difference between high self-esteem and low self-esteem about the product. The study used the questionnaire method to find out the control effect of self-esteem on apparel brand types. The survey data was analyzed by SPSS Hangul 10.0 Statistic Package. 16 apparel brands that had been selected by a preliminary study were surveyed by using. Brand Mapping was performed in each group for brand classification, and ANOVA was conducted in order to compare the variables depending on brand types. The self-esteem was surveyed by using the self-esteem scale by Rosenberg was used. Multivariate analysis was conducted to identify brand preference, product involvement according to purchase intention and the interactive effects of the brand types that are divided into familiarity and control recognition. For the purpose of the study was to compare searched the results of the high self-esteem comparison with the low self-esteem. The results of the study found the differences on perception about the brand between the high self-esteem and the low self-esteem on the preference. People with high self-esteem liked the brand that was perceived obedience. But the low self-esteem liked the brand that was perceived control.

Purpose: The purpose of this study was to identify the relationship of self-differentiation, family function and mental health among adolescents. Methods: The data were collected from 967 adolescents and analyzed using descriptive statistics, t-test, ANOVA, Scheffe's test, Pearson correlation coefficient and Stepwise multiple regression with the SPSS program. Results: Mental health differed according to grades, sibling position, father's education and mother's education. Self-differentiation and family function had a significant negative correlation with mental health. Multiple regression analysis showed recognition.emotional function, emotional cutoff and family projection as influencing self-differentiation. Grades, affective responsiveness in family function, and sibling position explained 20.8% of the total variance in mental health. Conclusion: The findings show that self-differentiation and family function influence mental health, indicating a need to develop nursing intervention programs to enhance adolescents' mental health and prevent negative outcomes. For these programs, the family must be included.

This study found out the influence of CCTV recognition and Self-efficacy on job satisfaction for 275 child care teachers working at daycare centers in Chungcheongbuk-do Province, and verified the regulation effect of Self-efficacy in the process. SPSS(Statistical Package for Social Science) 22.0 was used for data analysis. The results of the study are as follows: First, it was found that factors such as the guarantee of child's right, the guarantee of teachers' rights, and the self - efficacy were influential factors on the job satisfaction of the child care teachers. Second, it has been confirmed that the guarantee of teachers' rights and self-efficacy on the job satisfaction of child care teachers have a regulation effect. This study can be meaningful in that it provided basic data to enhance the quality of child care services by analyzing the factors of influence on the job satisfaction of child care teachers and presenting specific measures accordingly.

The purpose of this study was to investigate the university students' recognition and preference of Korean rice cakes. Self administered questionnaires were collected from 302 students in Incheon area. Statistical data analysis was completed using a SPSS 10.0 program. The recognition of Korean rice cake was generally high: Injeolmi, Garaeddeok, Bakseolgi, Songpyun, Patsirooddeok, Bindaeddeok, Yaksik Julpyun, Gyungdan, Moojigaeddeok were high1y recognized, but Gaesungjooak, Sugyibyung, Seunggeomchopyun poorly recognized by university students. The most common consumption frequency rate of students was once or twice a month (Male 31.9%; Female 41.6%). Most students ate rice cakes as snack with water, Kimchi, fruits, beverage(Cola, Cider) and Korean traditional beverage(Sujunggwa, Sighye). The sales possibility of Korean rice cake at university canteens was dependent on the characteristics different from those of rice cafes itself, for example,. nutritional labelling, mass, atmosphere and package, etc.

The purpose of this study was to investigate the perception and preference of the general public about Korean traditional rice cakes. Self-administered questionnaires were collected from 511 residents in Seoul and its vicinities. Data was analysed by t-test and one-way ANOVA. The recognition of Korean traditional rice cake was generally low except for the items that could be easily seen as either seasonable or festive foods. There was a significant difference in the average score of recognition and preference for each kind of Korean traditional rice cake according to gender and age. Injulmi, Yaksik, Songpyun, Baiksulgi and Garaeduk are highly preferred Korean traditional rice cakes, whereas Suktanbyung, Dootupduk, Soemuriduk and Daechoodanja are poorly considered among the general public.

As an important key technology using on electronic devices, face recognition has become one of the hottest technology recently. The traditional BP Neural network has a strong ability of self-learning, adaptive and powerful non-linear mapping but it also has disadvantages such as slow convergence speed, easy to be traversed in the training process and easy to fall into local minimum points. So we come up with an algorithm based on BP neural network but also combined with the PCA algorithm and other methods such as the elastic gradient descent method which can improve the original network to try to improve the whole recognition efficiency and has the advantages of both PCA algorithm and BP neural network.
