Director Lee Chang-dong's movies deal mainly with the matter of subject as a human individual. He attempts to show how the subject as a human individual is structured in society through the characters in the movies. It can be seen that a considerable part of this is connected to the matter of subject which is maintained by Michel Foucault, a modern French philosopher. Foucault contends that the subject has lost its identity in the huge structure of society and has become the object. The subject is alienated within the power. The subject is also divided into normality and abnormality in the social structure. Particularly, the movie directed by Lee Chang-dong shows an individual containing consideration toward self and Foucault also showed his attempts in his later years to newly interpret the subject in the context of consideration toward self. Through this thesis, I attempt to examine the matter of the subject that the film director Lee Chang-dong and Foucault have in common.

Recently, a self-driving car have applied deep learning technology to advanced driver assistance system can provide convenience to drivers, but it is shown deep that learning technology is vulnerable to adversarial evasion attacks. In this paper, we performed five adversarial evasion attacks, including MI-FGSM(Momentum Iterative-Fast Gradient Sign Method), targeting the object detection algorithm YOLOv5 (You Only Look Once), and measured the object detection performance in terms of mAP(mean Average Precision). In particular, we present a method applying morphology operations for YOLO to detect objects normally by removing noise and extracting boundary. As a result of analyzing its performance through experiments, when an adversarial attack was performed, YOLO's mAP dropped by at least 7.9%. The YOLO applied our proposed method can detect objects up to 87.3% of mAP performance.

Object: In the present study, we compared the positive cytodiagnostic test rates with discrepancies using self-collection devices for cervical cancer screening. We made this survey to examine whether or not our self-smear preparation method using the Kato self-collection device contributed to an improved rate of detecting atypical cells compared with existing recommended preparation methods. Methods: Specimens were collected at 14 facilities handling self-collection methods, and samples were collected by a physician in 2 facilities. The chisquared test was performed using the SPSS ver. 20 statistical software to determine the relationships between the positive cytodiagnostic rate, specimen preparation methods, and self-collection devices. Results: Collecting cells using the Kato self-collection device and preparing liquid-based specimens, we obtained a significantly higher rate of positive cytodiagnosis and our results were equal to those obtained with the direct method. Conclusions: Taking into consideration increased needs for screening using the self-collection method in future, with even more improved test accuracy, a screening test that is acceptable to society needs to be established.

This study is to be used for research material for pastoral counseling, by analyzing grounded-theoretically how substance abusers' awareness of self and experience of relations affects problems in abusing drugs. The subject of this study was chosen as 9 prisoners who were able to participate in group counseling, among those who were in prison for substance abuse and had more than 6 months of penal servitude left. In addition, in order to indicate counseling research methods through this study, 12 group counselings were carried out during October 24th. 2002 and February 14th. 2003 and verbatim were written out to be used as original material. After the research material was analyzed, they could be categorized into 60 concepts on the whole from 'conflict' and 'constraining thinking' to 'rationalization' and 'avoidance'. When these concepts were organized into groups of similarity, there were all together 20 categories. From this study, it can be found that substance abusers had "problems about self" and "problems about relations". The factor which affected their use of drugs was the area of relations, where as henceforth their use of drugs, the situation in which they could not escape from the use of substances was affected by problems within the area of self. When facing such problems as substance abuse, the pastoral counselor must create a holding environment through counseling, and perform good enough mothering by being insightful and providing active support on the problem. They must also help one's growth into "an empathizing self", "an accepting self", "a trusting self", "a hopeful self", who can empathize, accept, trust and hope, through experience in separation from the problem, conversion, meta-communication, self-rumination, relations and inspiration of hope. Likewise, the church must be able to act as a "place of growth and skill" which aids in the forming of relations and helps to be aware of self through experience in, and understanding of, relations.

The indoor areas for the commercial use of automatic monitoring systems of mobile robot localization improves the cognitive abilities and the needs of the environment with this emerging and existing mobile robot localization, and object recognition methods commonly around its great sensor are leveraged. On the other hand, there is a difficulty with a problem-solving self-location estimation in indoor mobile robots using only the sensors of the robot. Therefore, in this paper, a self-position estimation method for an enhanced and effective mobile robot is proposed using a marker and CCTV video that is already installed in the building. In particular, after recognizing a square mobile robot and the object from the input image, and the vertices were confirmed, the feature points of the marker were found, and marker recognition was then performed. First, a self-position estimation of the mobile robot was performed according to the relationship of the image marker and a coordinate transformation was performed. In particular, the estimation was converted to an absolute coordinate value based on CCTV information, such as robots and obstacles. The study results can be used to make a convenient self-position estimation of the robot in the indoor areas to verify the self-position estimation method of the mobile robot. In addition, experimental operation was performed based on the actual robot system.

This study attempts to develop a skeleton model to link construction schedule and 3D object for drawings in 4D system. Generally, the construction schedule and 3D object can be linked in 4D system by imported files which are made in specific S/Ws such as CAD S/W and scheduling S/W. Those methods have a difficulties for operating 4D data because extra work needs to link 4D data for each activity. This study develops a 4D model which the 4D data can be self-generated within the system. The suggested model can reduce the initial input data for new project by integrating schedule and 3D object in 4D system.

Weakly electric fish uses active sensing to detect the distortion of self-generated electric field in the underwater environments. The active electrolocation makes it possible to identify target objects from the surroundings without vision in the dark sea. Weakly electric fish have many electroreceptors over the whole body surface of electric fish, and sensor readings from a collection of electroreceptors are represented as an electric image. Many researchers have worked on finding features in the electric image to know how the weakly electric fish identify the target object. In this paper, we suggest a new mechanism of how the electrolocation can recognize a given target object among object plants. This approach is based on the differential components of the electric image, and has a potential to be applied to the underwater robotic system for object localization.

3D object detection generally aims to detect relatively large data such as automobiles, buses, persons, furniture, etc, so it is vulnerable to small object detection. In addition, in an environment with limited resources such as embedded devices, it is difficult to apply the model because of the huge amount of computation. In this paper, the accuracy of small object detection was improved by focusing on local features using only one layer, and the inference speed was improved through the proposed knowledge distillation method from large pre-trained network to small network and adaptive quantization method according to the parameter size. The proposed model was evaluated using SUN RGB-D Val and self-made apple tree data set. Finally, it achieved the accuracy performance of 62.04% at mAP@0.25 and 47.1% at mAP@0.5, and the inference speed was 120.5 scenes per sec, showing a fast real-time processing speed.
