최창원 ( Choi¸ Changwon ) 산업진흥원 2021 산업진흥연구 Vol.6 No.1

齊白石是20世紀中國近代多產的、深刻影響現代中國國畫的大師。其用一生的勤奮與追求將中國傳統文人畫的發展帶入到了世界藝術的殿堂。齊白石先生的畫作風格迥異, 內涵豐富, 有充滿童心、童趣的《芭蕉群雛圖》, 雖筆稚墨拙卻情趣盎然。也有樸實老成的《牡丹》暮年之作, 蒼勁有力, 動人心弦。還有諷刺現世, 批駁醜惡的《不倒翁》, 發人深省。當然, 最為值得去研究的還是齊白石先生的山水畫, 他的山水畫, 超越了其所在的時代, 在中國現代山水畫變革中具有獨特的歷史價值, 他是20世紀中國山水畫變革的開拓者之一。在本文中, 通過對齊白石先生的山水畫作的研究整理, 發現齊白石先生山水畫的特點, 以及其超越時代之處. Qi Baishi is a prolific master of modern Chinese painting in the 20th century and a profound influence on modern Chinese painting. With a lifetime of diligence and pursuit,he brought the development of traditional Chinese literati painting to the palace of world art. Qi Baishi's paintings have very different styles and rich connotations. There is a childlike "Plantain Crowd",which is childish but full of interest. There is also a simple and old-fashioned "Peony" in the late years,vigorous and powerful,moving heartstrings. There is also the irony of the present world,refuting the ugly "Tumbler",which is thought-provoking. Of course,the most worthy of study is Qi Baishi's landscape paintings. His landscape paintings surpassed their era and have unique historical value in the transformation of modern Chinese landscape painting. He was one of the pioneers of the transformation of Chinese landscape painting in the 20th century. In this article,through the research and collation of Qi Baishi's landscape paintings,the characteristics of Qi Baishi's landscape paintings and their surpassing of the times are discovered.

Joint Subcarrier Assignment and Power Allocation in Full-Duplex OFDMA Networks

Changwon Nam,Changhee Joo,Saewoong Bahk IEEE 2015 IEEE TRANSACTIONS ON WIRELESS COMMUNICATIONS Vol.14 No.6

<P>Recent advances in the physical layer have demonstrated the feasibility of in-band wireless full-duplex which enables a node to transmit and receive simultaneously on the same frequency band. While the full-duplex operation can ideally double the spectral efficiency, the network-level gain of full-duplex in large-scale networks remains unclear due to the complicated resource allocation in multi-carrier and multi-user environments. In this paper, we consider a single-cell full-duplex OFDMA network which consists of one full-duplex base station (BS) and multiple full-duplex mobile nodes. Our goal is to maximize the sum-rate performance by jointly optimizing subcarrier assignment and power allocation considering the characteristics of full-duplex transmissions. We develop an iterative solution that achieves local Pareto optimality in typical scenarios. Through extensive simulations, we demonstrate that our solution empirically achieves near-optimal performance and outperforms other resource allocation schemes designed for half-duplex networks. Also, we reveal the impact of various factors such as the channel correlation, the residual self-interference, and the distance between the BS and nodes on the full-duplex gain.</P>

Activity and Safety Recognition using Smart Work Shoes for Construction Worksite

( Changwon Wang ),( Young Kim ),( Seung Hyun Lee ),( Nak-jun Sung ),( Se Dong Min ),( Min-hyung Choi ) 한국인터넷정보학회 2020 KSII Transactions on Internet and Information Syst Vol.14 No.2

Workers at construction sites are easily exposed to many dangers and accidents involving falls, tripping, and missteps on stairs. However, researches on construction site monitoring system to prevent work-related injuries are still insufficient. The purpose of this study was to develop a wearable textile pressure insole sensor and examine its effectiveness in managing the real-time safety of construction workers. The sensor was designed based on the principles of parallel capacitance measurement using conductive textile and the monitoring system was developed by C# language. Three separate experiments were carried out for performance evaluation of the proposed sensor: (1) varying the distance between two capacitance plates to examine changes in capacitance charges, (2) repeatedly applying 1 N of pressure for 5,000 times to evaluate consistency, and (3) gradually increasing force by 1 N (from 1 N to 46 N) to test the linearity of the sensor value. Five subjects participated in our pilot test, which examined whether ascending and descending the stairs can be distinguished by our sensor and by weka assessment tool using k-NN algorithm. The 10-fold cross-validation method was used for analysis and the results of accuracy in identifying stair ascending and descending were 87.2% and 90.9%, respectively. By applying our sensor, the type of activity, weight-shifting patterns for balance control, and plantar pressure distribution for postural changes of the construction workers can be detected. The results of this study can be the basis for future sensor-based monitoring device development studies and fall prediction researches for construction workers.

Using Korean Visual Phonics as an Intervention to Improve Pronunciation for Foreign Speakers in Korea

Changwon Seo,Jaehyun Ahn,Eunhae Shin,Seongjong Kim 한국영어교과교육학회 2018 영어교과교육 Vol.17 No.3

In recent years, there has been an increase in the number of international people choosing to learn the Korean language. However, many of them are struggling to speak Korean because of the complexity of the Korean phonemic system. Korean visual phonics is a strategy that has been used to improve Korean pronunciation for international students. There is evidence suggesting that students who learned pronunciation of consonants using the visual phonics strategy showed significant improvement when compared to students using more traditional methods. The results for vowels, however, were mixed. The visual phonics group performed better with monophthongs than dipthongs. This could be attributed, in part, to the complexity of combining two different, yet related, signs to make a single compound vowel. Based on these results, we know that Korean visual phonics can be used to improve certain aspects of pronunciation for learners, specifically articulation and phonation.

Sludge settleability detection using automated SV30 measurement and comparisons of feature extraction methods

Changwon Kim,김예진,Hoonsik Yeom,Soojung Choi,Hyeon Bae 한국화학공학회 2010 Korean Journal of Chemical Engineering Vol.27 No.3

The need for automation and measurement technologies to detect the process state has been a driving force in the development of various measurements at wastewater treatment plants. While the number of applications of automation & measurement technologies to the field is increasing, there have only been a few cases where they have been applied to the area of sludge settling. It is not easy to develop an automated operation support system for the detection of sludge settleability due to its site-specific characteristics. To automate the human operator’s daily test and diagnosis work on sludge settling, an on-line SV30 measurement was developed and an automated detection algorithm on settleability was developed that imitated heuristics to detect settleability faults. The automated SV30 measurement is based on automatic pumping with a predefined schedule, the image capture of the settling test with a digital camera, and an analysis of the images to detect the settled sludge height. To detect settleability faults such as deflocculation and bulking from these images, two feature extraction methods were used and their performance was evaluated.

Risking and Precautions: An Ex Ante Contractualist Perspective

Changwon Sung(성창원) 한국철학회 2021 철학 Vol.- No.147

최근 일군의 철학자들은 스캔런의 계약주의가 이른바 사후적인 도덕이론이 아니라 사전적인 것으로 해석되어야 한다고 주장한다. 사전적 계약주의는 어떤 원칙이 개인에게 부과하는 이득이나 해악의 기대값의 관점에서 해당 원칙을 정당화하는 구조를 지닌다. 이런 최근의 경향은, 사후적이 아닌 사전적 계약주의가 위태롭게 하는 행위의 허용 가능성에 대해 최선의 설명을 제공해줄 수 있다는 인식에서 비롯되었다. 본고의 주된 목표는 사전적 계약주의를 옹호하는 기존 시도들의 한계를 극복할 수 있는 새로운 관점을 제시하는 것이다. 필자는 기존 연구에서 큰 관심을 받지 못한 예방조치라는 개념을 강조하며 그것이 사전적 계약주의의 체계 내에 정합적으로 안착될 수 있음을 보인다. 궁극적으로 필자는 예방조치라는 개념 없이는 위태롭게 하는 행위의 허용 가능성을 제대로 설명할 수 없다고 주장한다. Several philosophers have recently argued that Scanlonian contractualism can be interpreted as an ex ante moral theory. This framework enables justifying a principle in terms of its prospects of benefit or harm for individuals. This has been ignited by the insight that ex ante, not ex post, contractualism can deal with the problem of risking, that is, the question of how we can make sense of the permissibility of risk-imposing activities. I develop an account of ex ante contractualism that can overcome the shortcomings of other existing defenses. The account centers on the neglected idea of precautions in the recent literature. My claim is that one cannot make sense of the permissibility of risky actions without recourse to the notion of reasonable precautions. After qualifying this claim by responding to some objections to it, I demonstrate that the idea of precautions can be incorporated into an ex ante conception of contractualism as an indispensable notion for the problem of risking.
