Generally, there is inconsistency in the relationship between family firms and CSR performance. On the one hand, family firms perform CSR because family firms consider socioemotional wealth the greatest motivation, building and maintaining their image and reputation. On the other hand, with respect to the agency theory, some studies insist that family firms affect CSR performance negatively and it is because family members often pursue private gains by taking advantages of their information and control, making a sacrifice of minority shareholder. Also, although many researches have considered corporate governance of family firms an important determinant of firms performance, there are lack of researches that explore the relationship between corporate governance of family firms and CSR performance. To fill these gaps, this paper looks into corporate governance of family firms in Korea and tests the effect of family ownership of family firms on CSR performance in Korea. Family ownership and foreign ownership are used as independent and moderating variables to test influences on CSR performance, dependent variable. The sample of 537 family firms is collected from KEJI Index from 2015-2017. The results show that there is a negative relationship between family ownership of family firms and CSR performance. Also, foreign ownership mitigates the negative relationship with positive moderating effect.ํ•œ๊ตญ์˜ ๊ฐ€์กฑ๊ธฐ์—…์€ ์™ธ๊ตญ์˜ ์„ ๋„๊ธฐ์—…๋ณด๋‹ค ๊ธฐ์—…์˜ ์‚ฌํšŒ์  ์ฑ…์ž„ ์„ฑ๊ณผ์— ๋Œ€ํ•œ ๋…ธ๋ ฅ์ด ๋ถ€์กฑํ•œ ์‹ค์ •์ด๋‹ค. ๋Œ€๊ฐœ ๊ฐ€์กฑ๊ธฐ์—…๊ณผ ๊ธฐ์—…์˜ ์‚ฌํšŒ์  ์ฑ…์ž„ ์„ฑ๊ณผ๊ฐ„์˜ ๊ด€๊ณ„๋Š” ๋ถˆ์ผ์น˜ํ•œ ์–‘์ƒ์„ ๋ณด์ธ๋‹ค. ๊ฐ€์กฑ๊ธฐ์—…์ด ์ข‹์€ ํ‰ํŒ๊ณผ ์ธ์ƒ์„ ์œ ์ง€ํ•˜๊ธฐ ์œ„ํ•ด ์‚ฌํšŒ ์ •์„œ์  ๋ถ€๋ฅผ ์ถ”๊ตฌํ•˜๋ฉฐ ๊ธฐ์—…์˜ ์‚ฌํšŒ์  ์ฑ…์ž„ ์„ฑ๊ณผ๋ฅผ ํ–‰ํ•œ๋‹ค๋Š” ์ฃผ์žฅ์ด ์žˆ๋Š” ๋ฐ˜๋ฉด, ๋Œ€๋ฆฌ์ธ ์ด๋ก ์„ ๊ธฐ๋ฐ˜์œผ๋กœ ํ•œ ๋‹ค๋ฅธ ์—ฐ๊ตฌ๋Š” ๊ฐ€์กฑ๊ธฐ์—…์ด ๊ธฐ์—…์˜ ์‚ฌํšŒ์  ์ฑ…์ž„ ์„ฑ๊ณผ์— ๋ถ€์ •์ ์ธ ์˜ํ–ฅ์„ ๋ฏธ์นœ๋‹ค๊ณ  ์ฃผ์žฅํ•˜๋Š”๋ฐ ๊ทธ ์ด์œ ๋Š” ๊ฐ€์กฑ๊ตฌ์„ฑ์›์ด ์†Œ์ฃผ์ฃผ๋ฅผ ํฌ์ƒํ•˜๋ฉด์„œ ๊ทธ๋“ค์˜ ์ •๋ณด์ , ํ†ต์ œ์  ์ด์ ์„ ๋‚จ์šฉํ•˜๊ธฐ ๋•Œ๋ฌธ์ด๋‹ค. ๋˜ํ•œ ๋น„๋ก ๋งŽ์€ ์—ฐ๊ตฌ์ž๋“ค์ด ๊ฐ€์กฑ๊ธฐ์—…์˜ ์ง€๋ฐฐ๊ตฌ์กฐ๋ฅผ ๊ธฐ์—… ์„ฑ๊ณผ์˜ ์ฃผ์š”ํ•œ ๊ฒฐ์ •์š”์ธ์ด๋ผ๊ณ  ์ฃผ์žฅํ•ด์™”์ง€๋งŒ ๊ฐ€์กฑ๊ธฐ์—…์˜ ์ง€๋ฐฐ๊ตฌ์กฐ์™€ ๊ธฐ์—…์˜ ์‚ฌํšŒ์  ์ฑ…์ž„์„ฑ๊ณผ๊ฐ„์˜ ๊ด€๊ณ„๋ฅผ ์กฐ์‚ฌํ•˜๋Š” ์—ฐ๊ตฌ๋Š” ์•„์ง๊นŒ์ง€ ๋ถ€์กฑํ•˜๋‹ค. ์ด๋Ÿฌํ•œ ๊ณต๋ฐฑ์„ ์ฑ„์šฐ๊ธฐ ์œ„ํ•ด์„œ ๋ณธ ๋…ผ๋ฌธ์€ ํ•œ๊ตญ๊ฐ€์กฑ๊ธฐ์—…์˜ ์ง€๋ฐฐ๊ตฌ์กฐ ์†์„ ๋“ค์—ฌ๋‹ค๋ณด๊ณ  ๊ธฐ์—…์˜ ์‚ฌํšŒ์  ์ฑ…์ž„ ์„ฑ๊ณผ์— ๋Œ€ํ•œ ๊ฐ€์กฑ์†Œ์œ ์˜ ์˜ํ–ฅ์„ ๊ฒ€์‚ฌํ•ด ๋ณด๊ณ ์ž ํ•œ๋‹ค. ๊ฐ€์กฑ์†Œ์œ ์™€ ์™ธ๊ตญ์ธ์†Œ์œ ๋Š” ๊ฐ๊ฐ ๋…๋ฆฝ๋ณ€์ˆ˜์™€ ์กฐ์ ˆ๋ณ€์ˆ˜๋กœ ์‚ฌ์šฉ๋˜์—ˆ์œผ๋ฉฐ ์‚ฌํšŒ์  ์ฑ…์ž„ ์„ฑ๊ณผ๋Š” ์ข…์†๋ณ€์ˆ˜๋กœ ์‚ฌ์šฉ๋˜์—ˆ๋‹ค. ํ‘œ๋ณธ์€ 2015๋…„๋ถ€ํ„ฐ 2017๋…„๊นŒ์ง€ KEJI Index๋กœ๋ถ€ํ„ฐ ์ˆ˜์ง‘ํ•œ ์ด 537๊ฐœ์˜ ๊ฐ€์กฑ๊ธฐ์—…์ด๋‹ค. ๋ณธ ๋…ผ๋ฌธ์€ ๊ฐ€์กฑ๊ธฐ์—…์˜ ๊ฐ€์กฑ์†Œ์œ ์™€ ๊ธฐ์—…์˜ ์‚ฌํšŒ์  ์ฑ…์ž„ ์„ฑ๊ณผ๊ฐ„์˜ ๋ถ€์ •์ ์ธ ๊ด€๊ณ„๋ฅผ ๋ฐœ๊ฒฌํ•˜์˜€๋‹ค. ๋˜ํ•œ ์™ธ๊ตญ์†Œ์œ ์˜ ์ฆ๊ฐ€๊ฐ€ ๊ฐ€์กฑ์†Œ์œ ์™€ ๊ธฐ์—…์˜ ์‚ฌํšŒ์  ์ฑ…์ž„ ์„ฑ๊ณผ๊ฐ„์˜ ๋ถ€์ •์ ์ธ ๊ด€๊ณ„๋ฅผ ์•ฝํ™”์‹œํ‚ด์œผ๋กœ์จ ๊ธ์ •์ ์ธ ์กฐ์ ˆํšจ๊ณผ๋กœ ์ž‘์šฉํ•˜์˜€์Œ์„ ์ฆ๋ช…ํ•˜์˜€๋‹ค.TABLE OF CONTENTS 1.

One of the attractive point of ROMP is that living (controlled) polymerization is possible. Using this point, extensive research has been done to prepare various polymers having precise structures. However, still there are many challenges to be improved such like introducing new functional monomers and development of more complex nanostructures. This thesis describes the synthesis of polymers having precise structures by controlled ROMP and possible features as a nano-sized material. Firstly, the conformation control of dendronized polymer was done by changing the generation of dendrons, linker moiety, and back bone structure. The single chain conformation was analyzed by MALLS analysis and visualized by AFM imaging technique. As a result, rigid rod-like conformation was obtained using high generation (G5) of dendrons or TD based macromonomers, and all these homopolymerization showed living manner. Using this living ROMP of NB and TD monomers, block and gradient copolymerization could be achieved by conventional sequential addition method and batch method, respectively. Resulting two copolymers showed clear structural difference, existence of boundary, from the AFM image. This successful and first example of synthesis of gradient copolymer by batch method via ROMP was possible because of different reactivity between two monomers. According to the kinetic study, TD monomer does faster initiation and slower propagation compare with conventional monomer NB. It increase the ki/kp ratio and enable the controlled ROMP even with slow initiating but stable 2nd generation Grubbs and Hoveyda-Grubbs catalysts. With this advantage, three-arm star polymer was synthesized by core first method via ROMP for the first time. In addition, controlled ROMP of monomer containing alkyne moiety was achieved without protection group due to the fast initiation of TD monomers. Lastly, various block copolymers (BCP) were prepared using living ROMP of NB and TD based monomers, to fabricate polymer nanostructures. Large size domain structure was obtained from dendronized BCPs under the comparatively mild condition due to the extended conformation and large size of dendrons. In the case of BCP with PA block, thermally/mechanically stable nanocaterpillar structure was obtained during the polymerization by strong ฯ€-ฯ€ interaction between conjugated polymers. Also, redox responsive self-assembly was demonstrated from the BCP containing ferrocene moiety.Abstract i Contents iii List of Schemes v List of Tables vii List of Figures ix Chapter 1 : Introduction 1.1 Ring opening metathesis polymerization (ROMP) 1 1.2 Thesis research 5 1.3 References 7 Chapter 2 : Conformation Control of Polymer and Single-chain Analysis 2.1 Introduction 9 2.2 Experimental 12 2.3 Results and Discussion 2.3.1 Different generation of ester type dendron 19 2.3.2 Different backbone structure 30 2.3.3 endo-tricyclo[4.2.2.02,5]deca-3,9-diene monomer 34 2.4 Conclusion 42 2.5 References 43 Chapter 3 : Structural Analysis of Copolymers using 1D Rod-like Dendronized Polymer 3.1 Introduction 46 3.2 Experimental 48 3.3 Results and Discussion 3.3.1 Diblock copolymerization 50 3.3.2 Gradient copolymerization 54 3.3.3 Comparison the structure of two copolymers 60 3.4 Conclusion 62 3.5 References 63 Chapter 4 : Controlled ROMP of TD Based Monomers 4.1 Introduction 64 4.2 Experimental 68 4.3 Results and Discussion 4.3.1 Living ROMP using 2nd generation Grubbs and 2nd generation Hoveyda-Grubbs catalysts 75 4.3.2 Three-arm star polymer 86 4.3.3 Controlled ROMP of monomer containing alkyne moiety 90 4.4 Conclusion 100 4.5 References 101 Chapter 5 : Fabrication of Polymer Nanostructure using ROMP polymer 5.1 Introduction 104 5.2 Experimental 106 5.3 Results and Discussion 5.3.1 BCP with two kinds of dendrons 110 5.3.2 Insitu nanoparticlization of conjugated polymer (INCP) 116 5.3.3 Self-assembly behavior of BCP containing ferrocene 126 5.4 Conclusion 133 5.5 References 134 Abstract in Korean 136 Abstract in German 138Docto
