Ethnic return migrants and identity in Korea

Gao Ming 한국외국어대학교 국제지역대학원 2015 국내석사

South Korea has long been regarded as a homogeneous country and correspondingly its immigration policy appears to be tight as well, yet Korean Chinese (Chosonjok or Josonjok) is not that group of people. They ‘enjoy’ another set of immigration policy that separates them from other overseas Koreans and other foreigners in South Korea. This thesis argues that, based on the concept that ethnic identity is subjective and dynamic, Korean Chinese have gone through a process of transformation of ethnic identity. For this reason, the current study expands the body of research on multi-dimensional perspectives on ethnic identity transformation by examining legal, social and economic dimensions Korean Chinese have experienced after return migration. Finally, the author shows the emergence of ethnic minorities and mature migration industry may become a sign of permanent settlement in South Korea. Areas for additional research and exploration of policy are also discussed. 한국은 오랫동안 단일민족 국가로 간주되어왔으며 이민정책 또한 이에 상응하여 단단한 것처럼 보인다. 그러나 조선족은 그러한 정책의 그룹에 속한 사람들은 아니다. 그들은 다른 해외 자국민이나 한국에 있는 외국인과는 분리되는 또 다른 이민정책을 누리고 있다. 본 논문은 민족정체성은 주관적이고 역동적이라는 개념에 기초하여 조선족은 민족정체성의 변형 과정을 경험하고 있다는 것을 주장한다. 이런 이유로 본 연구는 회귀이민/역 이동 (Return Migration) 이후 조선족의 경험을 법적, 사회적, 경제적 차원에서 검토함으로써 민족정체성의 변형에 대한 연구를 다차원적 관점에서 확장하고 있다. 마지막으로 필자는 한국에서 소수민족과 성숙한 이민산업의 출현이 영구적인 정착의 징후가 될 수 있다는 것을 제시하고 있다. 또한, 부가적인 연구 분야와 정치에 대한 탐구를 논의하고 있다.

Gao, Ming 경북대학교 대학원 2017 국내석사

With the economic globalization, today’s global markets have been full of commodities from every country, geographic limitations and distance sense have gradually disappeared, and the competition between enterprises from each country has been increasingly fierce. Chinese domestic markets have showed the enormous demanding potentials, making the enterprises in every country of the world will not give up Chinese markets easily. For consumers, choose famous brands have more guarantees, so Samsung, Apple and Xiaomi smartphones can occupy the dominated market shares in the fiercely competitive Chinese markets. Brand is not only a brand, but also the intangible assets of competition for an enterprise. And the favorable brand image is the powerful weapon in the market competition, which deeply attracts consumers. The goal of this research is the effects of country, corporate and brand image on purchase intention-in Chinese markets, the adjusting effects of smartphone brand is the center. This paper collects data in the form of questionnaires, select three representative smartphone brands in three countries for comparison,and the investigated objects are Chinese consumers who have used Samsung, Apple, Xiaomi or have the purchase intention or purchase plan. In this paper, total 620 copies of questionnaires were released, of which 596 copies of effective questionnaires were collected. SPSS 22.0 and AMOS 22.0 were used for a hypothesis test and following results of study are produced. Chi-square difference method was applied to compare adjusting effects. The goal of this research is the effects of country, corporate and brand image on purchase intention-in Chinese markets, the adjusting effects of smartphone brand is the center.

SPSS 22.0 and AMOS 22.0 were used for a hypothesis test and following results of study are produced. Chi-square difference method was applied to compare adjusting effects. In the results, hypothesis 1 to 4 are all founded, country, enterprise and brand image have all the positive effects on purchase intentions. In the process of adjusting effects, among the factors that influence the brand attitude of consumers, international image and brand image have no difference according to different brands. While purchasing different brands of smartphones, Chinese consumers do not pay attention to the country image of this brand, but focus on the brand image itself. In the process of buying mobile phones, consumer will decide whether they will buy because of brand attitude affected by different enterprise images of smartphone manufacturing enterprises. Samsung smartphone users pay the most attention to brand image, Xiaomi follows, and Apple users will not decide whether they will purchase smartphone due to the good or bad enterprise image. The limitation of this study is that among investigated objects, the general ratio of females aging from 20 to 30 is excessively great,but young people and females do not pay attention to political problems generally, so it may influence the general assessment of country image. The prices of products in every brand are different, and the characteristics of confronted groups are also different. Therefore, in the future research, except for noticing the representation of questionnaires, it should also choose the products with the same price level in the brands for comparison.

Cost Effective Error Detection for SoC Validation and Online Testing

Gao, Ming University of California, Santa Barbara 2012 해외박사(DDOD)

Error detection is the vital component of the quality assurance tasks during the life time of an integrated circuit to avoid costly in-field failures and massive product recall. Nevertheless, sufficiently thorough error checking requires the development of high quality tests and on-chip checkers that can themselves be very expensive. How to detect all the errors while minimizing the cost remains one of the most challenging and critical questions for the semiconductor research community. This dissertation attempts to address this issue by proposing several cost effective error detection techniques targeting the stages of post-silicon validation and online testing. First, a time-multiplexed checking scheme is proposed to accommodate on-chip hardware checkers with low overhead. The same hardware resource for checker implementation can be used as a design-for-debug (DfD) structure for post-silicon debugging and later reused as a design-for-testability (DfT) resource during online testing. Case studies and mathematical analyses demonstrates the schemes provide high error coverage and a significant reduction in chip area and power overhead for on-chip checkers at the cost of increased fault detection latency. Second, a series of test evaluation metrics are proposed based on error models of electrical bugs and data mining based fault-model-free approach. Experimental results demonstrate that the intelligent navigation of validation test plan based on relevant bug model or knowledge mined from post-silicon test data can prioritize those tests capable of uncovering more silicon timing errors, resulting in significant reduction of validation time and effort.

Gao, Ming Mitch State University of New York at Stony Brook ProQue 2022 해외박사(DDOD)

Processes with independent and stationary increments are named Levy processes. The Normal Inverse Gaussian (NIG) type Levy process as a Normal variance-mean mixture with an Inverse Gaussian mixing distribution, has greater flexibility and can fit the empirical asset returns exceptionally well, making this process a great interest from a mathematical finance point of view.The paper is organized as follows. In the first part, we briefly review the fundamental concepts of the general Levy processes, NIG, and its properties and parameters estimation. In the second part, we describe the financial modeling for asset prices, option prices, and the term structure of interest rate. In the third part, we perform an empirical study on NIG process and its application in option pricing. We firstly show the Monte Carlo simulation techniques of NIG process. Secondly, we examine the NIG fitness for selecting asset classes, including ETFs, volatility index, exchange rate, cryptocurrency, and interest rates. Lastly, we provide the empirical results of NIG option pricing under both Esscher transform and the Mean-correcting martingale measure, followed by a detailed comparison study between NIG greeks and BS greeks. In addition, we experiment with new methods of calculating the implied volatility based on the Levy space and Levy time under the Esscher transform. The last part comprises the conclusions and future work.

Gao, Ming Jle 충북대학교 2018 국내박사

A corporation, as an economic entity, plays an important part in the development process of society. In the present, the idea of sustainable development in which economy, society and environment are in harmony has emerged. And because of that, the need to corporate ethics are also emphasized. Corporate ethics, a criterion on rightfulness of corporate actions, appeared as social values evolved in the course of history. This research studies two main issues, “what is corporate ethics?” and “how has Chinese corporate ethics developed so far?” The purpose of the research is to discuss and analyze comprehensive theory system of corporate ethics, look at the development process of Chinese corporate ethics based on theoretical background, examine changes and characteristics of Chinese corporate ethics by stage, and suggest their implications. For this purpose, chapter 1 talks about background, purpose, necessity, and method of the research. Chapter 2 deals with theoretical consideration of corporate ethics. Chapter 3 analyzes the development process of Chinese corporate ethics by policy change. Chapter 4 discusses characteristics of Chinese corporate ethics through analysis of related laws. And chapter 5 comes to a conclusion of the research. This research proves that corporate ethics includes two factors, that is, a ‘criterion’ that makes a decision about rightfulness of corporate actions and ‘purpose’ that is completed by the corporate actions meeting the ‘criterion.’ In addition, as for the development of Chinese corporate ethics, the fundamental cause of various social problems from the absence of corporate ethics is related to the profit relationship between local government and corporations resulted from a change of economic system. At last, this research analyzes the influence of policies and laws on corporate ethics during the change of Chinese economic system and suggests a development model of Chinese corporate ethics based on the analysis results.

유도 영상 필터를 이용한 다중 스케일 분할 톤 매핑 기법

Dynamic range is the ratio between the brightest and the darkest luminance values. The dynamic range visible to human vision can reach 〖10〗^5 and the dynamic range of high dynamic range (HDR) image can be between 〖10〗^4–〖10〗^5 while ordinary low dynamic range (LDR) images are only 〖10〗^2–〖10〗^3. Since the higher dynamic range images contain more information, HDR images tend to have a stunning visual effect. However, since the dynamic range of ordinary monitors is too low to display HDR contents, a tone mapping process is needed. The tone mapping is a method used in HDR image processing which can compress high dynamic range images to a low dynamic range. Commonly, the tone mapping technology uses an edge-preserving filter to decompose the original image. Guided image filter (GIF) is one of the edge-preserving filters which has an excellent effect. The GIF is used to divide an image into a base layer and a detail layer, then the range of the detail layer is reduced with a compression function to enhance the detail information of the image. However, in most cases, an image includes the detail and edge information in different scales. That is to say, it is difficult to represent all detail features under a certain scale, and a single-scale image decomposition method is not free from artifacts around edges. To solve the problems, the multi-scale image decomposition method is proposed in this thesis. It utilizes the detail layers of several scales to determine how much edge is preserved. Experiment results show that the proposed algorithm has better performance in preserving edge compared to conventional algorithms.

High-performance Magneto-rheological Elastomers (MRE) based on Ethylene/Acrylic Elastomer (AEM)/CIP composite

가오톈밍 수원대학교 2018 국내박사

자기유변탄성체(MRE)는 마이크로 크기의 자기 응답 입자와 탄성체, 첨가제로 이루어진 스마트 재료이다. MRE의 기계적, 유변학적, 동적 물성은 외부 자기장에 의해 변화한다. 그렇기에 MRE는 많은 과학자들이 자기유변물질에 관심을 가지게 했고, 폭 넓은 활용성을 얻었다. 하지만 실제 현장에서 사용하기에 MRE의 기계적, 동적 물성은 너무 낮고, 그 원인은 무기물인 자기 응답 입자와 유기물인 탄성체 간의 낮은 계면 결합력 때문이다. Ethylene/acrylic 탄성체인 AEM은 포화 구조를 가진 고무 재료로, 저온특성과 압축저항이 우수할 뿐만 아니라 내열성, 내유성, 노화 저항성 역시 우수하여 자동차 산업에서 씰, 가스켓, 방진 소재에 사용된다. 또한 낮은 무니 점도에 의해 가공이 용이하다. 이번 연구에서는 서로 다른 보강재로 충전된 AEM의 물성을 비교하였다. 또한 이방성 MRE의 제조 및 carbonyl iron particles(CIP)과 탄성체 간 계면 결합력 강화 기술에 대해 연구하였다. 연구 결과, 기계적 물성과 자기유도 물성이 확실히 개선됨을 확인하였고, 이러한 고성능의 MRE는 실제 현장에 적용시킬 수 있다. 연구 내용은 아래 목록에 나열하였다. 1. 서로 다른 종류의 보강재로 충전된 AEM 물성의 비교 서로 다른 보강재(carbon black and fumed silica)로 충전된 AEM의 물성을 비교한 결과, carbon black과 달리 silica가 가교 속도에 영향을 끼치는 것을 확인하였다. 또한 carbon black은 AEM 내에서 좋은 분산성을 보이며 높은 인장강도, 낮은 영구 압축률과 payne effect를 나타내었다. 따라서 AEM의 보강재로 carbon black이 더 적합하다고 판단하였다. 2. 서로 다른 제조 방법에 따른 AEM 기반 MRE의 미세 구조 및 동적 기계적 물성 자기유변탄성체(MRE)는 자기 응답 입자의 배열에 따라 등방성(i-MRE)와 이방성(a-MRE)으로 분류되며 이방성 MRE는 CIP가 사슬형태의 구조를 형성한다. 이방성 MRE-1은 자기장의 적용과 탄성체의 가교를 동시에 진행하는 one-step 공정으로 제조된 반면, 이방성 MRE-2는 자기장을 가하여 CIP의 배향을 유도한 뒤 가교를 시키는 two-step 공정으로 제조했다. 그 결과 MRE-1에서는 CIP의 사슬 형태의 배향이 확실히 생성된 반면, MRE-2에서는 그러지 않았다. 이방성 MRE-1의 인장강도가 가장 낮은 이유는 고무 분자사슬과 CIP간의 계면 결합력이 존재하지 않기 때문이며 등방성 MRE에서 인장강도가 가장 높았다. MRE의 저장 모듈러스(G’)와 MR 효과는 CIP 배향에 따른 효과이며, 제조 방법이 미세구조와 자기 유도 물성에 끼치는 영향에 대해 설명하였다. 3. AEM 기반 MRE와 금속 산화물의 적용 AEM 기반 MRE의 고성능화를 위해 ZnO에 주목했다. ZnO는 AEM 기반 MRE에 두가지 기능을 나타내는데 그중 한 기능은 AEM 내에 금속 리간드 구조를 생성함으로써 기계적 물성을 향상시키고, AEM 내 에너지 손실을 보인다. 또 다른 기능은 카르보닐기와 아민기 사이의 촉매작용이다. 이렇듯 ZnO는 기계적 물성의 강화 뿐 아니라 CIP와 탄성체 사이의 계면 결합력을 향상 시켜 자기유도 물성을 강화한다. 또다른 금속 산화물인 MgO 역시 시도한 결과 매트릭스 내에 금속 리간드 구조 형성을 나타내었지만 촉매 작용은 보이지 않았다. 4. AEM 기반 MRE에서 탄산칼슘의 계면 상용화제로의 역할 CIP의 표면은 양전위를 나타내는 반면, 탄산칼슘은 음전위를 나타낸다. 또한 탄산칼슘은 AEM 분자사슬과 같이 카르보닐기를 가지고 있다. 따라서 탄산칼슘은 AEM 기반 MRE의 상용화제의 기능을 할 수 있다. 연구 결과 탄산칼슘이 CIP 표면에 흡착된 것을 확인하였고, 탄산칼슘이 충전됐을 때 응력 전이에 의해 자기유도 물성의 향상을 보였다.
