Exploring Neuronal Heterogeneity in the Drosophila Nervous System with Novel Neurotechnologies

Li, Ye ProQuest Dissertations & Theses University of Mich 2019 해외박사(DDOD)

The complex nervous system is built upon a vastly heterogeneous population of neurons. In order to decipher how the nervous system operates, it is critical to understand all aspects of neuronal properties such as morphology, lineage, electrophysiology and molecular identity, etc. Canonical neuronal subtype classification is often based on features reflected in one of these attributes. However, canonically defined neuronal subtypes normally compose of individuals that are heterogeneous in other attributes. It is therefore important to study the same neuron based on a collective cohort of properties. In this thesis study, I studied the lineage composition, morphology patterning and molecular heterogeneity of the serotonergic neurons in the fruit fly Drosophila melanogaster. I developed a series of novel transgenic tools, collectively called Bitbow, which are capable of generating up to tens of thousands of unique fluorescent barcodes to unambiguously label hundreds of lineages or individual neurons in the same brain. My results indicated that most of the serotonergic neurons arises from distinct lineages. Combining with Expansion Microscopy and multispectral neuronal tracing, a morphological map of serotonergic neurons in the ventral nerve cord was reconstructed from a single Bitbow fly. Using scRNAseq techniques, I found profound molecular heterogeneity of serotonergic neurons, characterized by their differentially expressed genes of GPCRs, ion channels, neurotransmitters, transcription factors and so on. My thesis has provided new methodologies to better define neuronal subtypes with multiple modalities, and accumulated knowledge to allow more precise investigations and manipulations of Drosophila serotonergic neurons in future studies.

3-D Wing Flutter Analysis of AGARD Wing 445.6 with Fully Coupled Method

Ye, Wen Juan 충남대학교 대학원 2010 국내석사

Flutter is a self-feeding and potentially destructive vibration where aerodynamic force on an object coupled with a structure's natural mode of vibration to produce rapid periodic motion which will lead to a rapid damage to the structural body. So the flutter analysis plays a very important role in the design of airplane or bridge. In this paper, the flutter characteristics of AGARD Wing 445.6 were studied via the Fluid Structure Interaction (FSI) simulations which are based on the fully coupled algorithms. For solving of AGARD Wing 445.6 at the Mach number of 0.499-1.141, the CFD solver (CFX-5) was based on an unsteady, parallel, multiblock, multigrid finite for the Navier-Stockes equations. The CSD solver (ANSYS) was based on the time integration of modal dynamic equations extracted from full finite element analysis. A general multiblock deformation grid method was used to generate dynamically moving grids for the unsteady flow solver. The solutions of the aerodynamics and the structural dynamics were coupled strongly in time by fully implicit method. The results from the simulations were compared with the results from the some references and experiment performed in the Langley Transonic Dynamics Tunnel of USA known as the AGARD Wing 445.6 dynamic aeroelastic test cases. The conclusions are described as follows: (1) Flutter analysis of AGARD Wing 445.6 was conducted in this work by using three close-source programs: CFX-5, ANSYS, and MpCCI, and without using any code for program manipulation. (2) The flutter characteristics in both subsonic and transonic regimes have been investigated with fully coupled methods. These analysis results have shown that the dynamic instability in the subsonic regime is characterized as a sharp transition to a classical flutter, with bending-torsion coupling. Increasing the Mach number, there is a smooth transition to a different flutter mechanism, characterized by shock-movement locking in the first structural bending mode. (3) The computed flutter boundary got by fully coupled method was generally in good agreement with the experimental data and other similar aeroelastic simulations' results. The well catching of transonic dip of flutter frequency shows the strong evidence of the flow-solver's ability to model nonlinear fluid-structure interaction. (4) The successfully utilization of the fully coupling method of CFX-5 and ANSYS in this paper shows the fully coupling method is good speedup and efficiency for FSI problems comparing with other methods.

A Study on User Behavior Intention of Aesthetic AI APP Based on TAM and TPB : A Case from Animation APP

Ye FengHua 대전대학교 대학원 2018 국내박사

Abstract In the Internet era, the reading mode of the public is gradually turning to digital reading. Therefore, as a carrier of digital reading, mobile APP has been widely used by the public. However, the competitions of APP markets are fierce and various APPs have been increasingly emerging. Hence, how to make some innovations about APPs to attract the users to download and use has become a hot topic in the research of marketing strategy in the new era. Artificial intelligence has been considered as the fourth industrial revolution of mankind, and Artificial intelligence internet and AI APP have become a commercial trend. Therefore, an increasing number of scholars have begun to focus on these users’ customer behaviors. In this paper, we would take the Aesthetic AI APP of animation as research objects and mainly explored customers’ behavior intention about using aesthetic AI APP to reading or watching animation and then made discussions about the precision marketing strategies of aesthetic AI APP, which would not only fill the gap of theory, but also made some suggestions about precision marketing strategies for related enterprises and operators so that they could adopt some strategies to attract users and enhance corporate value.The study has the value of theory and Practice. we would comb and summarize some relevant literature about planned behavior theory, technology acceptance model, digital animation and animation aesthetic AI APP in this paper. And then based on these literature,we constructed the conceptual model of this paper and proposed some hypotheses. Furthermore, the conceptual model was proposed based on technology acceptance model, including four latent variables of perceived ease of use, perceived usefulness, attitude toward using and behavior intention. Besides, combined with planned behavior theory, subjective norms was introduced into this model too. Finally, considering the actual motivation of the consumer in the animation industry, perceived playfulness of customers was also introduced into this model. In this paper, we mainly explore the causality of these six variables described above. Hence, in order to examine the relationships between them, the questionnaire was designed, in which the scales of variables were cited from mature scales and would be made some adjustment to meet our research needs. After the design of questionnaire, we conducted random sample surveys using on-site questionnaires. Finally, we acquired a total of 374 valid questionnaires. Based on the data collection, descriptive analysis, reliability and validity analysis, correlation analysis, factor analysis would be made, then structural equation model would be employed to examine the relationships between variables in the conceptual model. Besides, path analysis would be made to explore the causality, influencing paths and effects between variables about aesthetic AI APP. The results showed that the hypotheses proposed in this paper were significance supported. First, customers’ perceived usefulness, attitude toward using and subjective norms about using aesthetic AI APP to read or watch animation would directly affect their behavior intention. Second, perceived usefulness, perceived ease of use, perceived playfulness would significantly and positively affect attitude toward using. Third, perceived ease of use, perceived playfulness would positively affect perceived usefulness. Besides, there exists some mediation effects. First, perceived usefulness would indirectly affect behavior intention through attitude toward using. Second, perceived ease of use, perceived playfulness would indirectly affect behavior intention through perceived usefulness and attitude toward using. Finally, perceived ease of use, perceived playfulness would indirectly and positively affect attitude toward using through perceived usefulness. Further, perceived usefulness has a most significant effect on customers’ behavior intention about aesthetic AI APP, whose coefficient is 0.389, and then is the attitude toward using, whose coefficient is 0.326, which indicate that perceived usefulness and attitude toward using would greatly and positively affect customers’ behavior intention about aesthetic AI APP. In addition, the direct effect of attitude toward using on behavior intention is largest while the second largest is perceived usefulness, whose coefficient is 0.307. Finally, based on the empirical results of questionnaire data, the precision marketing strategies about aesthetic AI APP would be explored. And there are three aspects that would be discussed. First, it’s essential to achieve personalized Precision marketing based on artificial intelligence technology. Second, it’s vital to achieve Precision forecasts of users’ behaviors and needs by using big data, artificial intelligence and prediction model. Finally, it’s necessary to promote precision marketing with the innovative 4P theory. In other words, it’s essential to optimize the product experience of APP to improve perceived usefulness and playfulness, to set dynamic prices to provide optimal solutions for users, to expand marketing channels to increase user loyalty and induce positive word-of-mouth effect, so that with big data and artificial intelligence technology, the precision marketing would be conducted in a customer-oriented way. key words: aesthetic AI APP, planned behavior theory, technology acceptance model, structural equation model, precision marketing

Learning to Explain Causal Rationale of Stock Price Changes in Financial Reports

Ye Eun Chun Graduate School of UNIST 2020 국내석사

When a critical event occurs, it is often necessary to provide appropriate explanations. Previously, several theoretical and empirical foundations which discover causes and effects in temporal data have been established. However, for textual data, a simple causality modeling is not enough to handle variations in natural languages. To address the challenges in textual causality modeling, we annotate and create a large causality text dataset, called ‘Causal Rationale of Stock Price Changes’ (CR-SPC) to fine-tune pre-trained language models. Our dataset includes 283K sentences from the 10-K annual reports of the U.S. companies, and sentence-level labels, from which we observe diverse patterns of causality from each industrial sector for stock price changes. Because of this diversity and an imbalance in training data across sectors, BERT+fine-tune baseline on Sector-only data shows a biased performance. We propose to transfer from related sectors, implemented as a two-stage fine tuning framework. First-stage fine tuning transfers from related sector, to overcome the limited training resource, then the second stage follows to fine tune for the given sector. Our proposed framework yields significantly improved results for detecting causal rationale from industrial sectors with low amounts of data. Furthermore, we generate labels for 382K unlabeled sentences and augment the size of the dataset by self-training on CR-SPC dataset.

A Study on The Experience of Artistic Conception Created with Neo-Chinese Style : Center on Expression Form of Chinese elements in Product Application

Ye Jialei 경기대학교 대학원 2021 국내박사

In the context of the continuing segmentation of the consumer markets, modern products come in increasingly diversified forms and styles. The consumer's aesthetic pursuit and their demand for quality of living bring in our sight products rich in cultural connotations. Meanwhile Chinese-style products have attracted wide attention with their rich Chinese cultural elements and have been used in many fields. This article intends to interpret the neo-Chinese style from the perspective of product design on the basis of home products, seek for modern design approaches for products in neo-Chinese style with cultural identity by contrasting the unique Chinese tradition of “Realm” appreciation with user experience in the experience-orient trend in today’s experience economy, and by the analysis of traditional Chinese artifacts, find and keep the features in their intrinsic pragmatism and cultural expressions which can meet the modern demands. Traditional Chinese artifacts contain rich Chinese cultural elements that reflect Chinese people’s views of life. The Chinese idea of human-nature harmony therein demands a symbiotic development of people and nature. Driven by this idea, products are endowed with features such as economy, environment-friendliness, healthiness, authenticity, etc., which happen to consist with the modern ideas of green design, harmonious design, healthy design, etc. Riding on the ongoing trend of product design of pursuing for experience, we exploit the inherent cultural features in Chinese products to seek for a unique neo-Chinese style that brings customers into a “realm” experience. To apply the current technologies to users’ demands, we reinvent Chinese household products to make them healthy, technology-rich, and with cultural tastes, the products that can help to relieve the increasingly heavy pressure of social and natural issues, and focus on creating a harmonious and healthy lifestyle for consumers. We hope to make the neo-Chinese style a guiding example for the development of Chinese manufacturing industry, by increasing the added values of products with their local features and promoting the healthy development of the peripheral fields. Composed of four chapters this article analyzes and studies on the realm building with Chinese elements on the basis of home products in neo-Chinese style. The first chapter mainly analyzes the background, significance, methods and status-quo of the research, and illustrates the innovations and practical significance of this research. The second chapter sorts through the development of the relationship between the neo-Chinese style and modern home products: the initial discussion of home products explain the feasibility of designing home products in the neo-Chinese style; then the development of the neo-Chinese style the cultural elements it conveyed are introduced in detail and the significances in them outlined; finally a refection on the current pseudo-Chinese style products reveals the limitations of the neo-Chinese style products. The third chapter mainly discusses the latest experience-oriented trend, the cultural experience provided by Chinese style products in the presentation of the Chinese "realm", and the prospects of the current trend. The fourth chapter is a summarization of the relevant methods for and principles in the "realm"-focused neo-Chinese design. Proper design elements and design principles are reached and enumerated from the perspectives of relieving social issues and meeting customers' latest demands by virtue of contemporary expression techniques and science and technologies and at the end of the chapter is a summary of the meaning to develop a neo-Chinese style based on "realm" experience. Neo-Chinese style is an attempt to upgrade Chinese-style products under the background of experience economy, to point a viable direction for the design of new Chinese products with the benefit of different modern disciplines and the development of science and technologies, integrate the ancient Chinese wisdom in creating things, Chinese traditional culture and views of life into new Chinese products, assign them new values with the help of various modern disciplines such as materials science, engineering, ergonomics, design aesthetics, economics, etc., so to fit them into the modern society and life and accepted by modern customers. Products will be re-packaged via the view of an international product designer into the neo-Chinese style that will promote Chinese culture to the world. By sorting out the features that characterize the neo-Chinese style, this article starts from the "realm" experience provided such products under the backdrop of the latest experience-oriented trend, summarizes relevant social issues and users’ needs, and reaches the related design principles that may guide the expansion and application of neo-Chinese style in product design that is presenting the Chinese "realm" via relevant design elements. The author hopes that the "realm" experience during product use will enhance their awareness of the cultural features of neo-Chinese style products so as to attract the customers’ attentions under the background of modern experience economy.

중국의 문화산업정책과 기획사의 전략변화 연구 : SM 엔터테인먼트를 중심으로

Ye, Weibo 고려대학교 대학원 2015 국내석사

최근 중국에는 해외 엔터테인먼트 회사들의 진출이 활발하다. 그러나 모든 진출한 엔터테인먼트 회사들이 다 성공하지는 않는다. 일본 AVEX 엔터테인먼트는 한국 SM엔터테인먼트보다 중국에서 먼저 법인을 설립했지만 결국에 중국시장에서 법인을 철수했다. 반면에 한국 SM엔터테인먼트는 중국 시장에 진출한 시기부터 지속적인 변화를 통해 성공을 얻었다. 기존의 연구들이 신제도주의이론으로 기업의 수동적 변화에 대해 많이 논의하고 있다. 즉, 기업환경 변화에 따라 기업이 수동적으로 변화하는 것이다. 그러나 기업은 단순히 환경에 따라 수동적으로 변화하는 것이 아니라 기업 내부의 자원을 활용해서 능동적으로도 변화한다. 그래서 본 연구는 신제도주의이론과 자원의존이론을 결합해서 SM 엔터테인먼트의 수동적 변화와 능동적 변화를 같이 분석한다. 그리고 SM 엔터테인먼트는 중국 문화산업정책의 발전초기에는 시장 개척, 기반구축 등 수동적 변화로 대응했으며, 중국 문화산업정책의 심화시기에는 현지화 전략, 제휴 전략 등 능동적인 전략변화로 대응하였다. 중국 문화산업정책의 변화는 문화산업정책의 등장 단계, 내용심화 단계 등 시기별로 정책들의 특징이 있다. 이러한 시기별의 중국 문화산업정책변화와의 관계를 연구하기 위해 SM 엔터테인먼트의 전략변화도 시기별로 구분해서 분석한다.

소비자 적대감과 기업태도의 관계에서 사회적 책임 활동(CSR)의 조절 효과

Ye, Tang 고려대학교 대학원 2015 국내석사

국제화가 촉진되고 세계시장 무대에서의 기업 간 경쟁이 확산됨에 따라 글로벌 경쟁은 심화되고, 기업들이 글로벌 소비자들을 이해해야 할 필요성은 높아지고 있다. 이와 함께 소비자들이 특정국가에 대해 갖는 적대적인 감정인 소비자적대감에 대한 이해 역시 필요성이 높아지고 있다. 이에 본 연구에서는 클라인 등(Klein et al.,1998)학자의 연구를 기초로, 중국 소비자들의 한국과 일본에 대한 적대감(역사적, 경제적)이 두 국가의 대표적인 자동차 기업에 대한 태도에 어떤 영향을 미치는지 살펴보고 소비자 지각된 기업의 사회적 책임활동(CSR)의 조절효과를 검토해보았다. 이를 위해, 중국의 20~50대 소비자를 대상으로 설문조사를 진행하여 연구수행에 필요한 자료를 수집하였다. 중국어 설문지를 작성한 후 온라인으로 베이징, 상하이, 광저우, 길림, 하남, 산시 등 6개 지역에 거주하는 344명 소비자를 대상으로 설문조사를 실시하였다. 설문응답은 2015년 4월 14~29일에 15일 동안 취합하였다 연구결과, 중국 소비자들의 한국에 대한 역사적 적대감은 유의미하지 않게 나타났지만 경제적 적대감은 유의미하게 나타났다. 더 나아가 경제적 적대감이 현대자동차 기업의 태도에 대해 부정적인 영향을 미치는 것을 검증하였다. 그리고 일본에 대한 역사적 적대감과 경제적 적대감 모두 유의미하고 도요타자동차 기업의 태도에 있어서도 부정적인 영향을 미치는 것을 검증하였다. 그러나 소비자 지각된 CSR의 조절효과는 유의미하지 않은 것으로 나타났다. 더 나아가 본 연구에서는 소비자 적대감과 제품태도의 상관관계를 측정을 해 보았다. 그 결과 경제적 적대감이 현대자동차와 도요타자동차 제품의 태도에 영향을 미치는 것으로 나타났다.

FDI spillovers in the China's automotive industry

Ye, Yanlin Graduate School of International Studies, Korea Un 2013 국내석사

China is one of the largest recipients of Foreign Direct Investment (FDI) in the world. Since 1980s, the Chinese government has chosen the introduction of FDI as a development path for automotive industry. However, it is difficult for the host country to get core technologies through formal technology transfer arrangements. Nevertheless, FDI is expected to bring about technology spillovers through various channels. Spillovers from FDI have been regarded as one of the most efficient means for technology dissemination. Therefore, it is practically important to study FDI spillovers in China’s automotive industry to acquire advance technologies and thus promote industrial development. This paper has two purposes. First, it is to identify historical development and characteristics of FDI in China’s automotive industry. Second, more importantly, it is to analyze spillovers from FDI. Theoretical analysis is used in the study to demonstrate transmission mechanisms of FDI spillovers. Also, influencing factors of spillovers are analyzed. Case studies are applied to give detailed illustrations and explanations. Over the years, FDI has increased rapidly in China’s automotive industry. Spillovers from FDI occur through demonstration effect, competition effect, linkage effect, and training effect, which contribute to the development of automotive industry in China. Still, limitations exist. After combining theories with the practice in China, this thesis provides policy implications for the government to make foreign auto firms commit more to their joint ventures. It also urges the Chinese automakers to enhance their absorptive capability, to which human capital is the key.
