HID(high intensity discharge)lamps are high pressure mercury lamp, high pressure sodium lamp and metalhalide lamp. metalhalide lamp among these lamps has considered to be one of the most effective artificial light sources and this lamp has good efficiency, good color rendition and good focusing capability, But the shortcorning of metalhalide lamp is known as acoustic resonance phenomena in the discharge tube when lighted by electronic ballast and then acoustic resonance cause various problems such as the arc instability, light output fluctuations. In this paper, to reduce the acoustic resonence phenomena, the electronic ballast was designed by three methods for high frequency operation wish frequency-modulated sinusodial waves in acoustic resonance frequency band. These frequency-modulated methods are resonance frequency and resonance frequency, resonance frequency and non-resonance frequency non-resonance frequency and non-resonance frequency Experiment results could't show the Presence of acoustic resonance visually and it proved that the resonance-generating conditions can be avoided by continuously changing the two operating frequencies in acoustic resonance band (20.59kHz∼94.2kHz).

Jian Wu,Wanqin Han,Tao Chen,Jiaqi Zhao,Binbin Li,Dianguo Xu 전력전자학회 2018 JOURNAL OF POWER ELECTRONICS Vol.18 No.3

Harmonic resonance exists in grid-connected inverter systems. In order to determine the network components that contribute to harmonic resonance and the composition of the resonant circuit, sensitivity theory is applied to the resonance characteristic analysis. Based on the modal analysis, the theory of sensitivity is applied to derive a formula for determining the sensitivities of each network component parameter under a resonance circumstance that reflects the participation of the network component. The solving formula is derived for both parallel harmonic resonance and series harmonic resonance. This formula is adopted to a 4-node grid-connected test system. The analysis results reveal that for a certain frequency, the participation of parallel resonance and series resonance are not the same. Finally, experimental results demonstrate that the solving formula for sensitivity is feasible for grid-connected systems.

Interplay of space-charge fourth order resonance and envelope instability

Jeon, D.,Jang, J.H.,Jin, H. North-Holland 2016 Nuclear Instruments & Methods in Physics Research. Vol.832 No.-

Since the finding of the space charge fourth order 4σ=360<SUP>o</SUP> resonance [Jeon et al., 2009 [3]], studies have been carried out to better understand the fourth order resonance and the envelope instability in high intensity linear accelerators. The questions remained unanswered under what conditions the envelope instability is excited or suppressed following the development of the fourth order resonance. Simulations suggest that the variation of σ<SUB>o</SUB> and σ along the linac, the halo particles and the resonance islands of the fourth order resonance play an important role in exciting or suppressing the envelope instability after the fourth order resonance is manifested for initially well-matched beams. Here σ(σ<SUB>o</SUB>) is the depressed (zero-current) phase advance per cell. The envelope instability is excited from the mismatch generated by the fourth order resonance, 1) when σ<SUB>o</SUB> is maintained approximately constant or increases along the linac with σ<SUB>o</SUB>>90<SUP>o</SUP> and 2) when the extent of the fourth order resonance shrinks, as σ increases approaching 90<SUP>o</SUP>. On the other hand, when σ stays almost constant (maintaining the fourth order resonance) or when σ<SUB>o</SUB> decreases and gets close to 90<SUP>o</SUP> (getting out of the envelope instability), the envelope instability is suppressed and the halo particles formed by the fourth order resonance preserves a four-fold structure in the phase space.

김은연,윤미선,김향희,남정모,박은숙,홍성화 대한이비인후과학회 2012 Clinical and Experimental Otorhinolaryngology Vol.5 No.1

Objectives. Resonance problems in hearing impaired (HI) individuals have been described as aspects of nasality. However,there are limitations in being able to explain the range of resonance problems. Therefore, this study suggests a perceptual rating that will effectively explain the characteristics of resonance problems in HI individuals. Methods. Nasalance scores were obtained from 32 subjects in each of HI and normal hearing (NH) groups using a nasometer. The subjects were categorized into groups based on normal and abnormal nasalance ranges. The abnormal nasalance range group was further divided into hyper-, hypo-, and mixed-nasal groups. Nasalance scores were based the individuals performance in a series of passage and syllable tasks. The perceptual rating was evaluated using a newly introduced tool, ‘vertical focus of resonance’ (VFR), which focuses on the resonance energy in the frontal, throat,pharyngeal and nasal locations. Results. The NH group demonstrated a significantly lower nasalance score in the oral coupling and passage tasks than the HI group. Based on the results of nasalance correlation analysis, the HI group showed highly significant correlations between syllable and passage tasks, as contrasted with the NH group. There were significant differences in VFR between the nasalance types in both the NH and the HI groups. Conclusion. The HI hyper-nasal group showed tendencies of velopharyngeal opening, as opposed to the HI hypo-nasal group which showed tendencies of velopharyngeal closure. The HI mixed-nasal group showed inappropriate coordination of velopharyngeal function. In the HI group, the results of VFR showed that the air flow and the resonance energy were not released from the cavity of resonance. The suggested VFR tool explains the focusing characteristics of resonance energy within a continuation of speech sound regardless of the phonetic environment. Therefore, VFR may be a useful tool in explaining the deviant resonance patterns of HI individuals.

CONCEPTUALISING BRAND CHARISMA

Siobhan Hatton-Jones,Min Teah,Ian Phau 글로벌지식마케팅경영학회 2017 Global Fashion Management Conference Vol.2017 No.07

The conceptualisation of brand charisma is multi-disciplinary, using luxury branding context. This research adds value by making significant contributions by extending and building theory; holds managerial implications for policymakers and brand managers in shaping and communicating brand charisma; additionally to develop a research framework and scale to measure brand charisma. Introduction Charisma in grounded in anthropology and sociology; which has been divided into three key definitions. At the root of the sociological construct it is associated with a leader who generates extremes of loyalty and motivation among followers (Smothers 1993).The primary reason charisma is used, historically speaking, is to gain control over a group of people, and create a strong following (Weber 1946; Dow 1968; Smothers 1993). Research has demonstrated that charismatic leaders are more likely to effect and motivate individuals (followers) beyond expectations and command extremes of attachments (Bass 1985, 1988; Conger 1988; House et al 1988). This implies that charisma can inspire devotion to a leader that surpasses mere loyalty (Spencer 1973; Dow 1968); an irrational bond and inspiration between leader and follower (Marcus, 1961). As competition continues to grow within the luxury sector brand resonance is increasingly important as some of the effects include: higher loyalty to the brand, increased number of followers, ease to move consumers, development and diffusion of new products and greater consumer accommodation for the brand. In recent years, as brands try to become more ‘accessible’ to consumers and provide them with more brand experiences online we see the brand become diluted and evidence of brand fatigue set in (Business Insider 2015). Brand experience has been conceptualised as ‘sensations, feelings, cognitions, and behavioural responses evoked by brand related stimuli’ (Brakus et al 2009); which are often subjective and internal responses (Brakus et al 2009). Most experiences occur directly when consumers shop, buy, and consume products. Experiences can also occur indirectly—for example, when consumers are exposed to advertising and marketing communications, including Web sites. As a majority of luxury brand consumers are deemed to be loyal to the brand, it is important to capitalise on these followers (Levitt 1975) to further foster brand- follower- consumer engagement. Pastor et al (2007) were able to demonstrate that followers’ emotional responses have a significant influence on charismatic leaders; where followers experienced higher levels of arousal, they were more likely to rate leaders as charismatic. Brands can have charisma through social construction, compelling emotional associations that build on imagery, symbolism and prestige. Thus, it leads to extraordinary levels of motivation and attachment- achieving brand resonance. Thus, followers and consumers will view the brand as being sacred, and imbued with deeply significant and metaphorical meaning (Smothers 1993). It is evident that brand charisma allows the brand to exercise control and influence over a following or group of consumers. As brand charisma serves as a motivational tool to inspire and communicate their brand vision to followers, it allows the charisma to remain unique and rare (only for those in the community). While the ability to attain this brand charisma is always kept out of reach for everyday consumers, in order to motivate them to perform and engage with the brand beyond expectation. From the followers perspective, charisma is used to communicate or signal to others their social belonging and identity to a particular community. The presence therefore of brand charisma serves as a guide, or vision, of the brand that is aspirational and inspirational for the followers, with the promise of the ‘dream’ being attainable by belonging to this group. It is interesting, and pivotal to note that brand charisma is not like a normal brand- follower relationship, but rather a unique bond that is value laden, ongoing and influential on perceptions. Some key characteristics have been used in forming a conceptual definition of brand charisma, form both the brand and follower perspective. These include “exercise diffuse and intense influence over the beliefs, values, behaviour and performance of others through own behaviour and example” (Dow 1969; House et al 1991; Shils 1965); “unique connection between leader and follower that can account for extraordinary performance and accomplishments of individuals, work groups, units and organisations” (Yammarino et al 1992; Bensman and Givant; Conger and Kanungo 1998); “transcendent from the ordinary” ; “the process is both parallel and analogous process…both change meaning and perceived value” (Weber 1922; 1966; Levitt 1975; Smothers 1993). Drawing from the above emerging characteristics, which is reflective of the literature, a tentative conceptual definition of brand charisma has been proposed below: “The ability to articulate the brand vision, elicit a positive emotional response by its audience or followers that is characterised by extremes of motivational attachment” Through a content analysis of luxury brands and a rigorous literature review, has identified ‘core’ and ‘supplementary’ characteristics for the presence of brand charisma, which is aimed to be further explored. The Core characteristics of brand charisma can be thought of as the source of the brands charismatic aura and this must be present for charismatic brands; while the supplementary characteristics are not crucial or inherent to every charismatic brand. Research Gaps Based on the extended literature review, the following key gaps have been identified: 1. To the best of my knowledge there has been no conceptualisation of brand charisma in marketing and branding (e.g. Smothers 1993; Dion and Arnould 2011) a. Lack of working definition for brand charisma and lack of research framework and scale to measure brand charisma 2. Diminutive studies have used the concept of charisma in luxury branding or marketing 3. Assessing whether brand charisma should be implemented or is present across various ‘categories’ of luxury (e.g. inaccessible vs. affordableluxury) 4. Past studies have not addressed the influence of brand charisma on consumer emotions and perceptions (e.g. Dion and Arnould 2011) Based on the above research gaps the following research questions have been developed: RQ1: What is brand charisma? RQ2: How does the presence of brand charisma influence brand resonance? RQ3: Does the presence of brand charisma differ between affordable and inaccessible luxury? RQ4: What are the emotional responses elicited by the presence of brand charisma? Theoretical Framework and Hypotheses Development Stimulus- Organism- Response (S-O-R) model is the underpinning theoretical framework for the proposed research (Mehrabian and Russell 1974). The S-O-R model has been widely used in retail environment (e.g. Buckley 1991; Chang et al. 2011) and to study different types of involvement (Arora 1982). Based on the S-O-R model, the stimulus is defined as any external stimuli that influence the internal states of an individual which consist of both environmental influence and marketing mix variable (Bagozzi 1978; Eroglu et al. 2003). In this proposed research the presence of brand charisma will serve as the external stimuli that influence consumers’ perception of luxury and brand affect. The perception of luxury is affected by brand related stimuli and imagery (Brakus et al 2009), which include but not limited to, elements such as; brand name, products sold and communications. Organism is defined as the internal emotional response which influences the relationship between external stimuli and the behavioural response (Bagozzi 1978). In this study, perception of luxury and brand affect will serve as the internal consumer responses (sensations, feelings and cognitions) which is degree to which a consumer is effected via the environment, being either direct or indirect, through the 5 senses (sensory appeal). In this study, the resulting response will be brand resonance, as this extends beyond loyalty and encapsulates a brand follower or consumer to willingly and proactively engage in word of mouth, have deep attachment or connection with the brand, feel proud of association with this brand and community followers (Keller 2001). Supporting Theory As brand charisma is a set of activities to capture the distinctive brand essence, which creates a strong sensory appeal compelling consumers to strongly advocate for the brand; we see the transfer of charisma onto the brand through concepts such as brand experience (consumer touchpoints) and brand resonance (brand- follower relationships). Thus, the Law of Contagion is the underpinning theory to support the effects of brand charisma (Frazer 1959, Mauss 1972; Tylor 1974). The Law of Contagion for the proposed research focuses on sympathetic magic, namely the effects of contagion, which deem that whatever is done to a material object will affect equally the person with whom the object was once in contact, whether it formed part of his body or not (Frazer 1889). This can be extended to brand activities such as communications, Furthermore, Spillover Effects, is the secondary effect of brand charisma as we are assessing the ‘spillover’ of charisma onto the brand and the effects it will have on the proposed relationships (Simonin and Ruth 1998) between perception of luxury, brand affect and brand resonance. Charismatic Leadership Theory (Weber [1922] 1978) has been deemed ‘transformational’, ‘visionary’ or ‘inspirational’ throughout the organisational literature (e.g. House 1977; Conger and Kanungo 1988). These theories focus on exceptional leaders who have extraordinary effects on their followers and larger social systems (Shamir et al 1993); hence leaders transform the needs, desires, values and aspirations of followers from self- interest to collective interest. This is demonstrated through brand communities, and kinship, as followers become highly committed to the leader’s mission and often perform above and beyond what is expected of them. Charismatic Leadership is further demonstrated through the strong relationship between follower and brand by; emotional and motivational arousal through brand behaviour, nonverbal communications, visionary and inspirational messages and ideological appeals. Therefore, in layman terms, the more charismatic brands are, the more likely they are to experience overall higher brand resonance. Brand resonance is the outcome variable proposed for this research. Brand resonance aims to capitalise on previously acquired loyalty and equity (Huang et al 2014); thus brands add value to consumer goods by supplying meaning, and consumers like brands because they package meaning derived from interaction with the brand (Biel 1970). This can further be explained by an enduring sense of communal kinship and affiliation; which sees followers of the brand invest personal resources in order to stay connected (Keller 2001; Huang et al 2014). Social Identification Theory (Tafjel and Turner 1985) is used to support the outcome variable of brand resonance, as one of the primary drivers of brand resonance is that followers draw some association or similarity between themselves and the brand. Social Identification Theory is also closely linked to Charismatic Leadership Theory (Shamir et al 1993) (discussed below), as brand behaviours define the boundaries of the collectivity to emphasise its distinctiveness, prestige and competition with other groups. Such leader behaviour increases the salience of the collective identity in members’ self- concepts (Ashforth and Mael 1989); therefore, identification with the leader (brand) as it is perceived via a representative character (brand activities). Based on the above, we postulate the following: H1: High Presence of brand charisma will lead to high perception of luxury H2: High perception of luxury will lead to high brand affect H3: High presence of brand charisma will lead to high brand affect H4: Perception of luxury mediates the relationship between presence of brand charisma and brand affect H5: High presence of brand affect will lead to high brand resonance Methodology My research will encompass a mixed methods approach and be split into three predominant phases. The first being scale development, followed by stimulus development and finally the main study. The mixed method offers greater depth and breadth of understanding and corroboration (Johnson et al 2007) and is in line with the underlying pragmatist paradigm of this study (Johnson and Onwuegbzie 2004). A convenience sample will be used comprising of consumer panel data. The sampling frame will consist of everyday consumers, as these consumers need not be buyers of luxury brands. Phase 1: Scale Development The scale development phase will use methods by Churchill (1979) and Devillis (1991). The purification, CFA, EFA and validity will be undertaken to refine and test the scale. The approximate sample for this phase is approximately 200 respondents. Phase 2: Stimulus Development This phase will use expert panel to select the most appropriate charismatic brand and stimulus to use for this research. The potential brands of interest, thus far guided by literature, are; Hermes, Chanel, Dolce & Gabanna, Gucci, Louis Vuitton, Valentino and Oscar de la Renta. The sample size of the expert panel will comprise of approximately 15-30 respondents (Endacott et al 1999; Keeney et al 2010). Phase 3: Main Study This phase will comprise of the self-administered questionnaire, with all sclaes measured on a 7- pinot Likert scale. With the use of an embedded stimulus, using consumer panel data with the sample size of approximately 800. Validation study will be included using psycho-physiological equipment available in the School of Marketing to validate the brand charisma scale; and to test whether there is positive emotions elicited that can be attributed to the charisma of the brand. This sample will consist of approximately 120, in line with recommended JCR guidelines. Significance Theoretical Contributions • Building and extending the current branding literature by conceptualising brand charisma, which has only been attempted in fragments throughout the literature. •Developing a scale to measure brand charisma in a luxury context. Until now, a brand charisma scale demonstrating rigour and validation is lacking within the literature • Empirically evaluating the developed brand charisma scale, validating the applicability and the moderating effects of brand charisma on the relationships between perception of luxury, brand experience and brand resonance. Methodological Contributions • This study will develop a brand charisma scale, employing psychometric properties to demonstrate reliability and validity. • This scale will then be used to further develop a Brand Charisma Index Managerial Contributions This study aims to provide a blueprint for luxury brand managers, owners and policymakers on: • How to use brand charisma to grow brand community, brand attachment and brand engagement; vis-a – vis the brand. • Build stronger brands, that are resilient to market changes and fluctuation • Segmentation process to identify consumers with high brand resonance To identify what cues of brand charisma should be present for brand content and campaigns and how to augment these • For inaccessible and affordable luxury offerings, identify whether the presence of brand charisma should be used for both. Provide insights how the presence of brand charisma can impact and influence consumer’s perceptions and emotional responses.

배경 및 목적: 이개는 두개골에서 돌출되어 있고, 이개강은 이개가 깔때기 모양으로 형성한공간을 말한다. 이개와 이개강은 소리를 모으는 기능을 하며, 해부학적으로 외이도와 연결되어 있다. 이 기관들은 해부학적 생리학적으로 연속되어 있어서 청각학적으로는 따로 구분하지는 않는다. 청각학적 재활에 있어서 보청기는 아주 큰 비중을 차지하고 있다. 그러나 보청기사용은 이개강과 외이도 공명의 일부를 상쇄하기도 하고, 보청기 종류에 따라 증폭기가 갖는이득보다 더 많은 이득을 제공하기도 한다. 보청기 사용으로 얻을 수 있는 추가 이득은 송화기위치 효과(microphone location effect; MLE)와 잔류 외이도 용적 등에 따라 달라진다. 이개와 이개강 공명은 MLE에 영향을 준다. 따라서 이개강 공명은 청각생리학적 측면에서 소리에대한 방향성 인지에 매우 중요한 단서를 제공하기 때문에 음원 방향 인지 연구에 중요하다.이 연구는 우리나라 성인의 이개강 공명 정상치를 구하고, 이개 크기가 이개강 공명에 영향을주는가를 알아보고자 한다. 방법: 이 연구는 정상 성인 18명 36귀(남:여=5:13)를 대상으로 하였다. 입사각 0°와 45°에서 이들의 이개강 공명을 구한 후, 이개 크기와의 상관관계를 분석하였다. 결과: 이개 크기는 상하 길이가 52.8부터 73.8 (61.7±5.5) ㎜이었으며, 너비가 16.35부터29.9 (22.4±3.3) ㎜이었다. 두 길이를 곱해 구한 면적은 458.62부터 1034.54 (706.21±165.58)㎟를 보였다. 최대 공명주파수는 음원 입사각 0˚와 45˚에서 모두 4 ㎑로 나타났으며, 최대공명이득은 0˚에서 12.2 (±2.9), 45˚에서 13.6 (±3.5) ㏈로 나타났으나 모든 주파수의 이개강공명이득은 이개 상하길이와 너비의 변화에도 불구하고 통계적으로 유의한 차이를 보이지않았다. 논의 및 결론: 결론적으로 이개크기는 이개강공명에 영향을 미치지 않는다. Background & Objectives: The pinna is located on the side of the head and forms the visible part of the hearing system. The cavum concha, an air-filled cone-shaped cavity deep within the ear canal, is also part of the pinna. Both of these structures collect sound and are connected to the external auditory canal (EAC). The pinna, cavum concha and EAC are not separated in the audiology field because these organs are connected anatomically and physiologically. Hearing aids play an importantroll in audiological rehabilitation. However, the use of hearing aids may cancel out the resonances of the cavum concha and EAC or may result in a gain higher than that of the electroacoustic gain. These variables differ among the different types of hearing aids. The value of the gain depends on to the microphone location effect (MLE) and the volume of the residual ear canal. The pinna and cavum concha influence the MLE. Hence, cavum concha resonance may play an important role in auditory physiology because resonance provides an important clue for direction determination. The goals of this study are to measure normative data in Korean adults and todetermine whether the size of the pinna influences the concha resonance. Methods: Eighteen healthy-young-adults (36 ears, M:F=5:13) participated in the present study. The resonance of the concha cavity was evaluated at azimuth 0° and azimuth 45°, and the relationship between the size of the pinna and the resonance of the concha cavity were analyzed statistically. Results: The mean height of the pinna was 52.8 to 73.8 (61.7±5.5) mm, the mean width of the pinna was 16.35 to 29.9 (12.2±2.9) ㎜, and the mean area of the pinna was 458.62 to 1034.54 (706.21±165.58) ㎟. The maximum resonance frequency was 4 ㎑ in both directions. The maximum resonance gains were 12.2 (±2.9) ㏈ at azimuth 0° and 13.6 (±3.5) ㏈ at azimuth 45°. The mean lengthof the concha cavity was 61.7 (±5.5), and its mean width was 22.4 (±3.3) ㎜. The sizes of the pinna and concha cavity were significantly correlated (p=0.01). However, there was not statistical significance between the size of pinna and the resonance of the concha cavity. Discussion & Conclusion: The results of this study suggest that pinna size does not affect the resonance of the concha cavity.

A Novel Control Method of PAPF for Resonance Damping and Harmonics Compensation in Power System

WU Longhui,ZHUO Fang,LI Hui,LIU Jinjun,WANG Zhaoan 전력전자학회 2007 ICPE(ISPE)논문집 Vol.- No.-

In power system, capacitors are widely used to compensate reactive power, which generally cause resonance problems in harmonic distorted network. In this paper, parallel active power filter (PAPF) is used to damp the resonances. Firstly, the damping characteristics of PAPF with traditional load current detection methods (detecting current including or not including the capacitor current) are analyzed respectively. The analysis results show that PAPF with traditional load current detection methods is effective for parallel resonance damping, but can not damp series resonance when capacitor current is not included in the detecting current. And when capacitor current is included in the detecting current, PAPF is prone to be unstable and can not damp parallel and series resonance. Then a novel control method of PAPF is proposed. PAPF with the proposed control method has excellent performance in damping of both parallel resonance and series resonance, whether the capacitor current is included in the detecting current of PAPF or not. Also the PAPF with proposed method has strong ability in harmonic compensation. Finally, the experiment results are presented to verify the analysis.

Magnetic resonance absorption in isolated metal/insulator/metal nanodot arrays with transmission geometry

Vo, T.S.,Surabhi, S.,Luong, C.H.,Yoon, S.G.,Lee, K.D.,Park, B.G.,Jeong, J.R. Elsevier 2015 Current Applied Physics Vol.15 No.7

In this study, we have systematically investigated a magnetic resonance absorption and tunability of absorption wavelength in isolated metal-insulator-metal (MIM) nanodot arrays with transmission geometry. The elemental electromagnetic resonances and their hybridizations are studied using 3-dimensional finite-difference time-domain (FDTD) calculation and resonance properties including the resonance peak tunability, magnetic permeability and quality (Q) factor are characterized with respect to the coupling strength. We have found the existence of electric and magnetic resonance mode in the MIM (Au/MgF<SUB>2</SUB>/Au) structure and the magnetic resonance has larger wavelength tunability than the electric resonance. The absorption cross section calculation revealed that absorption is the dominant extinction process at the magnetic resonance only. Magnetic permeability (μ) calculations for the various MIM parameters showed the maximum value of the imaginary part of μ is 16.1 with Q factor of 9.2 when the size of nanodot is 200 nm and the inter-dot distance is 300 nm. The presented calculations can be used to tune the response of the magnetic resonance absorption with a variable resonance wavelength and Q factor by using the simple MIM structures with transmission geometry.

들뢰즈의 “공명”으로 학습공동체 되어가기 -교사의 존재-인식론적 의미-

김성희 ( Kim Sung Hee ),안효진 ( Aha Hyo Jin ) 한국유아교육학회 2021 유아교육연구 Vol.41 No.2

Deleuze의 ‘공명’의 개념을 통해 급변하는 유아교육의 현장의 고민을 나누기 위해 모인 자발적 학습공동체의 이야기 흔적이다. 본 연구는 ‘공명’을 통해 교사로서 존재-인식론적 가치를 만들고 차이를 생성해가는 학습공동체 모습을 보여주는 것을 목적으로 한다. 후기 질적연구방법으로 연구자와 연구 참여자가 2019년 8월부터 1년간 지속적으로 만난 이야기 속에서 단순히 어떠한 의미를 만드는 것을 넘어서서 배움과 가르침에 대한 어떠한 생성을 만들어내는 가에 초점을 맞춰 기술하였다. Deleuze의 ‘공명’으로 학습공동체가 되어가는 과정을 살펴보면, 첫째, 마음 움직임으로의 ‘공명’, 둘째, 자기 회복의 ‘공명’으로 나타났다. 셋째, 새로움 생성의 ‘공명’으로 나타났다. 연구 참여자들은 각자의 배치 안에서 서로의 힘듦을 공감하고, 이 공감은 마음을 움직이게 하고, 이 마음 움직임은 서로를 자기 회복의 공명으로 치유의 순간을 경험하며, 이자기 회복의 공명은 일상 속 작은 차이를 만들어 나가고 새로운 사유의 감각을 촉발하게 한다. 본 연구를 통해 유아교사들이 공명을 통해 새로운 사유의 감각이 촉발되기를 기대한다. It is a story trace of a voluntary learning community gathered to share the concerns of the rapidly changing field of early childhood education through Deleuze's concept of “resonance”. The purpose of this study is to show the appearance of a learning community that creates existence-cognitive values and creates differences as a teacher through 'resonance'. As a later qualitative research method, the study focused on the creation of learning and teaching beyond simply making what meaning in the story that the researcher and the research participant met continuously for one year from August 2019. Looking at the process of becoming a learning community through Deleuze's “resonance”, first, “resonance” through mind movement, and second, “resonance” through self-healing. Third, it appeared as 'resonance' of the creation of newness. Participants in the study empathize with each other's hardships in their respective arrangements, this sympathy moves the mind, and this movement of the mind makes each other experience a moment of healing with the resonance of self-healing, and this resonance of self-healing is a small difference in daily life To create and spark a new sense of thought. Through this study, it is expected that early childhood teachers will spark a new sense of thought through resonance.
