  • 4차 산업혁명이 시작된 이래로 다양한 산업 분야에서 AI가 활용되고 있고, 그 중에서도 컴퓨터 비전 분야에서 딥러닝 기술이 각광받고 있다. 하지만 딥러닝 기술은 높은 전문 지식이 요구되어 관련 지식이 없는 일반인들은 활용하기 어렵다. 본 논문에서는 AI 관련 배경지식이 없는 사용자들도 UI를 통해 쉽게 이미지 분류 모델을 학습시킬 수 있는 노 코드 플랫폼에 관하여 기술하고, django 프레임워크를 이용해 웹 개발과 딥러닝 모델 학습을 통합 개발을 위한 아키텍처와 방향성을 제시하고자 한다. 사용자가 웹서버에 업로드한 이미지들을 웹 인터페이스를 통해 라벨링 하여 학습 데이터를 생성한 후, 이 데이터를 사용하여 모델을 학습시킨다. CNN 모델에 데이터를 학습시키는 과정과 생성된 모델 기반으로 이미지 예측하는 모듈을 통해 전문지식이 없는 사용자가 딥러닝 기술에 대해 쉽게 이해하고 이용하는 것을 기대할 수 있다.

  • 본 논문에서는 2개의 인-휠 브러쉬리스 모터로 구동하는 차량의 실시간 위치 추종 제어방법을 제안한다. 2개의 모터를 사용하여 구동되는 차량의 경우 방향 및 이동이 각 모터의 제어를 기반으로 결정된다. 하지만 컨트롤러에 의해 지령된 위치까지 모터의 제어가 정확하게 된다 하더라도 차량의 실제 위치는 바퀴와 바닥면사이의 슬립이나 외부 요인에 의해 오차가 발생하게 된다. 따라서 이렇게 발생하는 오차를 보상하기 위해 차량의 실시간 각도 추정이 가능한 IMU(Inertia Measrement Unit) 센서를 기반으로 진행 각도를 보정하며 주행 중 발생하는 위치오차를 보상하기 위해 모터의 홀센서로부터 계산되는 위치와 IMU 센서의 데이터를 조합하여 실시간 위치 추종 제어방법을 제안한다.

  • Currently, there is no definitive regulation for the appropriate frequency of data sampling in water distribution networks, yet it plays a crucial role in the efficient operation of these systems. This study proposes a new methodology for determining the optimal frequency of data acquisition in water distribution networks. Based on the decomposition of signals using harmonic series, this methodology has been validated using actual data from water distribution networks. By analyzing 12 types of data collected from two points, it was demonstrated that utilizing the factors and cumulative periodograms of harmonic series enables similar accuracy at lower data acquisition frequencies compared to the original signals.

  • Human mind consists of what he or she knows, namely 'a portion of awareness', as well as of what he or she does not know, namely 'a portion of unawareness'.1) Self refers to both consciousness and unconsciousness, whereas self-growth seems to be an ability with which a human being appropriately faces with the hidden desire and resistance of unconsciousness for himself and maintains its balance and unification with consciousness harmoniously. On this account, examination on character's unconsciousness seems to be an important methodological means to prospect for the original looks of self, based on character's internal psychology, and to grasp the change and growth throughout the course. Study subjects, namely and , are quite similar in internal/external factors around the leading character. Two girl leading characters, who have nested in parental influences and boundaries, confront with unfamiliar circumstances under the abrupt absence of parents. In order to resist contradictory and irrational situations there and to restore all the things to its original places, both carry out a hard adventure. Interestingly, both characters are similar in their unconscious characteristics, but they take different channels for their journey, confronting attitudes and changes of internal self. The purpose of this study was to examine the concrete origin of two characters' unconsciousness and then comparatively analyze the role of leading character's unconsciousness in the drama and its effects on the whole work. Therefore, the author tried to prove such a hypothesis as the probability and persuasiveness of story could be found out through establishing a character of higher completion degree and connecting between situations and events that are most appropriate for character's internal unconscious psychology.

  • Korean movies with a great variety of styles have recently succeeded in drawing people's attention Rule number one is "the more entertainment, the more audiences". On the top of box offices are always the movies that have a number of spectacular scenes, pounding sounds and big budget characters. Hong Sang Su movies, however, receive attention from the public without above noted descriptions. One of his effective methods of expression is "realism" He has illustrated the trivial episodes with his own wits and ways. Not only has his style become famous and popular but he has many followers. He enjoys using ordinary emotion and sentiment that are likely to happen to everyone. This paper uses two tools. One is the traditional analysis of realism. The other is how he can approach the public meaningfully by listing common elements he frequently uses in his movies. Nevertheless, we can't fully understand his realism by explaining how he shows our everyday life and how much his movie looks like it. Though admitting there are so many preceding papers on his works but this paper will try to look deep into his realism through the analysis of Mise-en-Sc$\grave{e}$ne.

  • We introduce a novel and versatile approach for preparing self-assembled nanoporous multilayered films with antireflective properties. Protonated polystyrene-block-poly (4-vinylpyrine) (PS-b-P4VP) and anionic polystyrene-block-poly (acrylic acid) (PS-b-PAA) block copolymer micelles (BCM) were used as building blocks for the layer-by-layer assembly of BCM multilayer films. BCM film growth is governed by electrostatic and hydrogen-bonding interactions between the oppositely BCMs. Both film porosity and film thickness are dependent upon the charge density of the micelles, with the porosity of the film controlled by the solution pH and the molecular weight (Mw) of the constituents. PS7K-b-P4VP28K/PS2K-b-PAA8K films prepared at pH 4 (for PS7K-b-P4VP28K) and pH 6 (for PS2K-b-PAA8K) are highly nanoporous and antireflective. In contrast, PS7K-b-P4VP28K/PS2K-b-PAA8K films assembled at pH 4/4 show a relatively dense surface morphology due to the decreased charge density of PS2K-b-PAA8K. Films formed from BCMs with increased PS block and decreased hydrophilic block (P4VP or PAA) size (e.g., PS36K-b-P4VP12K/PS16K-b-PAA4K at pH 4/4) were also nanoporous. Furthermore, we demonstrate that the nanostructured electrochemical sensors based on patterning methods show the electrochemical activities. Anionic poly(styrene sulfonate) (PSS) layers were selectively and uniformly deposited onto the catalase (CAT)-coated surface using the micro-contact printing method. The pH-induced charge reversal of catalase can provide the selective deposition of consecutive PE multilayers onto patterned PSS layers by causing the electrostatic repulsion between next PE layer and catalase. Based on this patterning method, the hybrid patterned multilayers composed of platinum nanoparticles (PtNP) and catalase were prepared and then their electrochemical properties were investigated from sensing $H_2O_2$ and NO gas. This study was based on the papers reported by our group. (J. Am. Chem. Soc. 128, 9935 (2006); Adv. Mater. 19, 4364 (2007); Electro. Mater. Lett. 3, 163 (2007)).

  • I try to elucidate the essence of cinematic art in terms of Nietzsche's physiological philosophy of art. According to Nietzsche, the mise-en-$sc{\grave{e}}nes$ in the film are expressions of willingness to the power of the author, the director. These are not re-imitations of the imitations with Platonic measure, sinker, number, but framing the elan vital Erde, die $urspr{\ddot{u}}ngliche$ Vorstellung with the director's body-camera. In this context, the film is essentially die Kunst des Lebens, in which the body and the earth are mediated by cameras. Therefore, it is not the eyes or the head, but the body that is necessary to appreciate film art. But the body at this time does not mean the heavy body of Hollywood standard audiences manipulated, controlled, or transformed by capital. We should stand in front of the film work with body shaking between trauma and Rausch, a dancing body, and a light and fresh body. Only by watching film with the body, can we achieve the small revolutions in everyday life. For example, if we watch $B{\acute{e}}la$ Tarr's film The Turin Horse in such a way, we can no longer be the dwarfed human beings, der Herde-Mensch. Also, $B{\acute{e}}la$ Tarr's mise-en-scene will make us realize why Nietzsche had said that there is art to us not to be destroyed by the platonic truth.

  • Chinese xian-xia films is a new genre that occurred through the fusion of the genre of martial arts and fantasy. This study analyzed the development of xian-xia films and the space aesthetics of xian-xia films through the miseenscene of the journey to the west films. In particular, the space for xian-xia in the films is divided into the human, urinary, heaven world and the space of conflict. It looks like the fantastic Middle Earth that Tolkien presented, however it is discriminatory in that it shows a highly Chinese appearance and overlapping world centered on the natural environment (the world of Mountains and Livers), such as mountains, deserts, caves, and grasslands, which usually appears in traditional martial arts history. Resently, the boom of journey to the west films is regarded as the change of the Chinese film industry under the influence of the development of IP (Intellectual Property) industry and the western fantasy genre in the 21st century China. This change marks the birth of the new Chinese fantasy "xian-xia" genre with the spirit of the present era that transcends the original world of journey to the west through the hybridization of the genre.
