최은성 忠南大學校 大學院 2016 국내석사

Dmitry Kabalevsky, a 20th century Russian composer and Pianist, is a person who made great achievement in the piano education of children. His pieces for piano education are composed systematically so that variety of musical components could be learned. Also it contains diversity in the musical grammar that it is useful teaching material for children, providing diverse musical experiences. Analysis and investigation on the technique of 30 Pieces for Children, op. 27 gives characteristics and the educational contents are as below. First, all the selected pieces are short musical sketches that are composed in A-B-Aˊ ternary forms and all have diverse titles and the moods that describe the title. Examples are the fourth piece “At Night on the River” expresses the way river flows and in the 29th, “Songs of the Cavalry” expression of running horse. Through the various musical experiences, children can learn piano with interest and can raise their emotional senses. Secondly, each piece is composed of different beats and various tonalities. The fourth piece “At Night on the River” has the beat of 3/4 in b minor, seventh “Old Dance” is 3/4 beat, a minor, twenty fourth “Etude” has 4/4 beat with F major, twenty ninth “Songs of the Cavalry” has the beat of 2/4 with b♭ minor. Thus, various beat can be sensed and different tonalities can be learned. Thirdly, each piece helps to learn the method of expressing according to the main melody. The positions of main melody are placed variously, such as that it is in the right hand, or left hand and even the two hands are in unison. Fourth, each piece contains various dynamics like piano, mezzo piano, mezzo forte, forte, fortissimo, sforzando, crescendo, decrescendo, and more of dynamic marks in detail. Through these dynamics, the theme can be described. Also, slow pieces can be played with soft melody and fast pieces can be played rhythmically and clearly. With these pieces with various tempos, children can experience the music’s flows. In the fifth, staccato, legato, non-legato, slur, mezzo staccato and many more various articulations are used along with various rhythms like dotted, triplet rhythms. Through these suggested various rhythms and articulations, various techniques can be experienced and learned. As analyzed above, Kabalevsky’s 30 Pieces for Children, op. 27 is a educationally valuable composition that lets the children learn of various musical components. In this paper, mainly Kabalevsky’s music were researched mainly, but hopefully, the research goes beyond including other 20th century composers’ pieces for children. Additionally, having basics on these researches, hopefully, educators can suggest many different educational texts for children learning piano.

본 연구는 인공지능 기반 음향 인식을 통한 교통사고 지점 탐지 시스템의 설계 및 구현이다. 우리나라의 도로 교통사고 사망률은 감소하는 추세지만 OECD국가 중 교통사고 사망자 수가 높은 편에 속한다. 우리나라는 교통사고를 줄이기 위해 지능형 교통 체계 도입부터 인공지능을 접목한 연구까지 진행하는 등 많은 노력을 기울이고 있다. 최근 연구되고 있는 CCTV로 수집한 영상을 인공지능 기반의 객체 인식 알고리즘을 통해 자동으로 사고를 탐지하는 방법을 상당히 높은 정확도로 많은 곳에서 활용되고 있다. 그러나 기존에 설치된 CCTV 영상의 화질 문제와 카메라를 새로 설치하기에는 비용이 상당하다는 문제가 있으며, 조명 변화, 날씨 조건 등의 외부 환경으로 인해 인공지능(AI)이 올바르게 작동하지 않을 수 있다. 이러한 문제를 해결하기 위해 객체 인식 알고리즘의 단점을 보완하는 음향 인식을 통한 교통사고 지점 탐지 시스템을 제안하고자 한다. 본 시스템은 사고 탐지를 위해 엣지단에서 오디오 데이터를 획득하고 서버로 전송한 후, CNN과 LSTM을 사용하여 사고 음향을 인식하고 사고 지점을 탐지할 수 있도록 하였으며, 이를 Front-End에서 시각화하여 모니터링할 수 있도록 시스템을 설계하였다. 여기서 CNN과 LSTM을 학습하기 위해 수집하기 어려운 사고 음향의 Mel Spectrogram을 적대적 생성 신경망으로 증강하였으며 이를 역변환하여 오디오 학습데이터셋을 구축하였다. 적대적 생성 신경망인 GAN, CGAN, MelGAN으로 각각 음향을 생성하였을 때의 LPIPS 지표를 통한 비교 분석과 주관적 평가를 수행하였으며, CNN과 LSTM 다중 클래스 분류 모델의 성능 분석을 ISO/IEC TS 4213을 기반으로 성능을 평가하였다. This study is the design and implementation of The Traffic Accident Spot Detection System using Sound Recognition Based on Artificial Intelligence. Although the death rate of road traffic accidents in Korea is decreasing, the number of traffic accidents deaths is among high among OECD countries. In order to reduce traffic accidents, Korea government is making great efforts, ranging from the introduction of an intelligent transportation system to research incorporating artificial intelligence. A method of automatically detecting accidents through an artificial intelligence based object recognition algorithm using images collected from CCTV, which are being studied recently, is being used in many places due to its fairly high accuracy. However, there are problems with the quality of existing CCTV images and the significant cost of installing new cameras, and the AI may not work properly due to external environments such as changes in lighting and weather conditions. To solve this problem, we propose The Traffic Accident Spot Detection System using Sound Recognition Based on Artificial Intelligence that complements the shortcomings of the object recognition algorithms. After acquiring audio data at the edge and transmits it to the server for accident detection, the system use CNN and LSTM to detect the accident sound recognition and infer the accident spot, which can be visualized and monitored at the front-end. In order to learn CNN and LSTM, the mel spectrogram of the accident sound, which is difficult to collect, was augmented with an adversarial generative neural network and inversely converted to construct an audio learning dataset. Comparative analysis were performed through LPIPS indicator and subjective evaluation when sounds were generated with GAN, CGAN, and MelGAN as adversiarial generative neural networks, and performance analysis of CNN and LSTM multi-class classification models was evaluated based on ISO/IEC TS 4213.

There are natation and universalism, semiosis and formality, logic and genealogy, usability in properties of mathematics, particularly logic is an remarkable property. The influence of mathematic terms in teaching and learning of school-mathematics is not insignificant in mathematics which is based on logic. To understand a concept in learning of mathematics, its term and notation can be precisely understanded and discriminated, also, when it is applied to a principle or a rule, one should precisely keep the prescribed regulation and order. Hence, the easy and usable expression for the mathematic terms will be a matter of concernment in mathematic education as well as it is necessary to research for the definitions. The development of the proper terms which is easy to understand for students is very important and urgent in mathematic education. Thus we survey the terms used in the mathematic text and the actual school until now, and we research the expression method of the terms which is easier to understand for students and can be associated to real concept.

Balanced Scorecard, or BSC, plays a vital role in public institutions as a way to make an objective and fair performance evaluation to create a more creative and productive organizational culture. The purpose of this study was to examine the relationship between BSC and organizational effectiveness in a quest to help boost the job satisfaction of organizational members and the efficiency of organizational performance. Concerning an analysis model, the validity, impartiality and practicality of BSC were selected as independent variables, and the selected dependent variable was organizational effectiveness, which were divided into three: job satisfaction, job commitment and organizational commit-ment. And eleven demographic characteristics including gender, age, job ranking, office and term of service were selected as trait variables. After an experimental analysis was carried out, the following findings were given: First, a hypothesis that a positive perception of BSC might affect organizational effectiveness in a positive way was tested, and it's found that validity and practicality had a significant impact on organizational effectiveness, and that impartiality didn't. Second, when a survey was conducted, most of the organizational members investigated felt the need for BSC, but they took a dim view of the introduction of it. It's needed to step up extensive publicity activities on BSC in order to let the organizational members have a full understanding of that without drawing a backlash from them. Third, there appeared several problems with the tryout of BSC in 2007. The multi-source evaluation put more strain on the members, and the overlapped evaluation indicators resulted in detracting from the validity of the evaluation, and that evaluation stirred up undesirable competition among them, which led to mutual distrust and waning organizational competitiveness. To turn around the situation, the introduction of a new system was required. Fourth, one of the problems with BSC was how to apply it to teachers, one of evaluates. It's quite unadvisable to evaluate teachers who teach students, but it's needed to consider in which way the performance management system could be applied successfully in consideration of the specificity of education such as the invisibility and long term of educational effects. Fifth, the application of BSC to the compensation system would make it possible to bolster the dynamism of the organization as much as possible. That should be applied to the compensation system to fortify the feedback function of it. Sixth, the key to the success of BSC was publicity and education. Difficult jargons such as performance indicator or KPI were elusive for everybody except people in charge. Specifically, teachers who didn't take care of a lot of administration work found it more hard to deal with such jargons. To remedy this problem, it's needed to create a new system to offer a helping hand to them in terms of performance management. In conclusion, the success of BSC hinges on the understanding and cooperation of organizational members who actually run and use the system, rather than on how to build it. As BSC is going to be applied to every division of the Chungcheongbuk-do Office of Education, the organizational members should direct their energy into understanding it to improve the performance of the individual divisions and entire organization. To make it happen, sustained and profound research efforts are called for.

Objectives: The goal of this study was determine the anti-inflammation mechanisms of Natrii sulfas (NS) on TNF-α induced activation on A549 (Human typeⅡ-like epithelial cells) cells. Methods: In the present study, we investigated the effects of NS on gene expression profiles in activated A549 cells using microarray. A549 cells were first cultured in 100 mm dish (1x106/ml) for 24h, and pretreated with 1 ㎍/㎖ NS or cotreated with 25 ng/㎖ TNF-α, 40 ng/㎖ IL-4, and 10 ng/㎖ IL-1β, or nontreated (control). Results: The gene expression profiles for the A549 cells varied depending on the NS. The cDNA microarray analysis revealed that cell adhesion molecule genes such as ITGB3, ITGB2, ITGA4, ITGB7, ITGB8, ITGB4, LAMA2, LAMA3, LAMA4, and FCER1G and inflammation-related genes such as Mmp15, IL1RAPL1, CMTM6, CSF1, CXCL13, CCL18, CXCL14, CCR4, CCBP2, TRAP1, MPEG1, and MSR1 and growth factor-related genes such as PDGFB, IGF2, FRS2, FGF5, and FGF7 genes were down-regulated in NS-treated A549 cells. We also observed extracellular matrix protein-related genes such as ECM2, COL3A1, COL1A2, COL14A1, COL12A1, COL10A1, and OMD and signal transduction-related genes such as VIPR1, TIMP2, and VIPR2 genes were up-regulated in NS-treated A549 cells. Conclusions: NS can affect cell adhesion, inflammation, growth factor, and extracellular matrix protein in NS-treated A549 cells. A microarray-based genomic survey is a high-throughput approach for the evaluation of gene expression in cell lines treated with NS.

The poet ‘Ki Hyeong-do’ has assured many readers and the research him was joined together continuously in spite of a shot literary world life and a little products. The reason was seen to come from his original poetic world distinguished with the other poets. That is, It is just that a negative, tragic view of the world and his own image contained a symbolic means even his poems, lifetime and deaths. His negativity of poem means a perfect break against a hope and out look. So It's not easy to find the reason of answer ‘yes’ in the his poetic world. The childhood which appeared on the stage of his poem is a space that can't be capable of a pain and suffering in young age. After the father died suddenly with paralysis, the mother taked on her's own shoulders the living and the sisters helped the household economy by delivery a newspaper other etc. So a young ‘Ki Hyeong-do’ possessed a in frospective nature came to more a lonely life. Besides in because death experience of sister and uncle's in boyhood. The features of his life became to a negativity and tragedy with a consistent tone. Accordingly In search for his poetic meaning, We have to say ‘The Death’ appeared in the poem. But It will not be able to explain that a ceremony of death experienced of which poverty and death in childhood. So, it will need to look around the time and space ceremoney expressed at the text. Also to grasp of those is because that can look in a poet's senses. His an idea of time shows a tragic reality recognition in the poem formed a continuous and made-up the world of death drawing death of future in the present. And Attachment regarding a empty space confines oneself in empty house and become attempted a break with the world. In causing of a sudden poet's death, it showed that urgent and dangerous despairs can be a total of the life to him from time to time. This is a reason that only 'death' will be reaming Look through Ki Hyeong-do´s poet. For a break with the world, till he rocked the door of himself in inside and he was confined, we will be able to share his death's ceremony internalized while following his life.
