정우식,Bong-Ki Min,Jeong-Hyun Park,Sang-Won Seo,Woo Sik Jung,안광순 대한화학회 2011 Bulletin of the Korean Chemical Society Vol.32 No.5

Alumina particles wrapped in few-layer graphene sheets were prepared by calcining aluminum nitride powders under a mixed gas flow of carbon monoxide and argon. The graphene sheets were characterized by powder Xray diffraction (XRD), Raman spectroscopy, electron energy loss spectroscopy, and high-resolution transmission electron microscopy. The few-layer graphene sheets, which wrapped around the alumina particles, did not exhibit any diffraction peaks in the XRD patterns but did show three characteristic bands (D, G, and 2D bands) in the Raman spectra. The dye-sensitized solar cell (DSSC) with the alumina particles wrapped in fewlayer graphene sheets exhibited significantly improved overall energy-conversion efficiency, compared to conventional DSSC, due to longer electron lifetime.

정우식 ( Woo Sik Jeong ) 현대중국학회 2009 現代中國硏究 Vol.11 No.1

모든 국가들은 발전전략을 수립할 때 무엇보다 중요하게 고려해야 될 요소 중의 하나가 지속가능발전인데, 이러한 측면에서 문화산업은 매우 유효적절한 분야라 할 수 있다. 본 논문은 중국문화산업의 수요자인 중국대중의 가치를 극대화시키는 분석방법인 3C(Company, Customer, Competitor)를 통한 정부, 기업, 소비자 등 시장참여자별 세부적인 분석으로 공급자위주 시장에서 수요자위주 시장으로 급변하는 중국문화산업을 보다 객관적으로 이해하고 향후 시장진입 후의 Risk Hedging에 유용한 정보를 제공하기 위함이다. 중국문화산업은 발전과정 및 중국 산업구조의 고도화 정도, 소비자들인 중국대중들의 소비성향, 중국정부의 의지 등을 고려한다면 중국의 문화산업 내수시장의 규모는 지속적으로 증대될 것이 확실하다. 다만, 시장규모의 증대가 시장 참여자간 다양하게 인과 되어 영향을 미칠 것이고 이에 따라 향후 나아가야 할 전략적인 방향도 차이가 날 것이다. 중국문화산업시장에 참여할 정부 및 기업에게 다음과 같이 제언한다. 정부는 중국문화산업의 조사연구에 보다 박차를 가해야 한다. 문화산업 관련기업들은 시장진입의 성공제고를 위한 피드백 시스템이 필요하다. 또한 기존 성공모델의 벤치마킹을 통한 기업에 optimized된 모델구축이 이뤄져야 한다. 이와 함께 시장진입에 필요한 조사시스템을 갖춰야 한다. 이를 통해 중국 시장 진입시 진출지역 및 진출분야의 고려가 이뤄져야 한다. 이에 단기적으로 대중문화 등 문화상품의 저변을 보다 확대해야 하며 장기적으로 기존 한국적 문화코드로 대변되는 `한류`의 재조명이 필요하다. 이러한 장기목표의 달성은 궁극적으로 우리의 지속가능성장모델(Sustainable Growth Model) 중 하나로 확립될 것이다. Most of all nation establish development strategy plan, One of most important factor is sustainable development. In this point, Culture industry is very useful and effective. This study`s majors analysis methods, for maximizing Chinese culture industry consumer`s (just as Chinese people) values, is 3C (Company, Customer and Competitor) method. main purpose of this study is for on this detailed analysis method more objective understanding Chinese culture industry and offer useful data about risk hedging after entry into market in the future. Considering Chinese culture industry development history, China industry structure, Chinese people`s propensity to consume and China government intentions, It is certainly that the domestic demand market scale of Chinese culture industry is constantly increasing. However, the market scale increases influence various factors between market participants, hence strategic direction have differences in the future. This study suggests government and companies joining in Chinese culture industry that government has important in research of Chinese culture industry and that for improving entry market, companies related in culture essentially need feed-back system, and in regards to existing success models establish optimized model by benchmarking analysis tool. Furthermore, Companies should make up of research system for entry market. On these various solutions when companies enter into market, they should consider entry areas and entry fields. In the short term we should expand and magnify culture commodity base and in the long term should re-illuminate "The Korean Wave-Hanllyu" representative of existing code of Korean culture. Ultimately, In achieving long term goal, We can establish one of our Sustainable Growth Model.

This study conducted an in-depth interview, a qualitative research methodology, to find out the subjective views of jazz club musicians and audiences about jazz club performances, and analyzed the contents and presented the results. The results of this study are as follows: First, jazz musicians perceived jazz clubs as the center point of their musician careers, and from the perspective of the audience, jazz clubs were a place where jazz lovers gathered voluntarily, and where they could enjoy musical communication in a comfortable atmosphere. Second, jazz club performances gave jazz musicians the autonomy to play and considered them suitable for creating optimized sounds, and the audience recognized that jazz musicians could experience performances vividly on stage close to the audience. Third, the way jazz musicians interacted with the audience was active for musical communication with the audience, and the audience preferred the way that interaction could contribute to their performance, and the audience recognized the interaction through musical communication with the musician and the musician s consideration for the audience. Fourth, jazz musicians played a major role in realizing a performance in which interaction with the audience was complete, and audiences perceived interaction as a joy of improvisation, a bond with jazz musicians, and a special experience. This study confirmed the jazz club s status as a cultural space for the public s jazz enjoyment as well as a performance base that ultimately promotes the development and spread of jazz gods in Korea, and it is meaningful that it can serve as a guideline for jazz performance planning and jazz club operation from an art management perspective.

중국 지역별 환경오염원 배출과 경제성장 간의 비교분석

정우식 ( Woo Sik Jeong ) 현대중국학회 2010 現代中國硏究 Vol.12 No.1

본 논문의 구성은 1) EKC의 이론적 배경, 해외 및 중국 선행연구 분석 2) 권역 및 지역별 환경오염원 배출 및 경제성장 간 비교분석 등 두 부분이다. 이를 통해 지속가능발전 전략을 추구하는 중국의 전체 및 지역별 환경오염원 배출현황, 정책적 방향 등의 경향을 파악할 수 있다. 중국은 환경오염원 배출량을 저감하기 위해서는 제조업 및 교통운수업 등의 에너지 사용에 있어 석탄사용량을 절대적으로 줄이고 지역적 편차를 극복하는 것이 관건이다. 즉, 경제규모가 크고 소득이 높은 지역의 배출량이 낮을 뿐 아니라 EP지수 및 GDP대비 비율을 보면 통제가 이뤄지는 것으로 나타났는데, 즉 scale effect에 따라 technique effect 및 composition effect가 존재하고 있다고 사료된다. 중국의 환경오염원 배출 및 경제성장과의 관계에서 일부지역을 제외하고 권역 및 지역별 경제수준은 여전히 낮아 환경오염원 배출량에 대한 결정요인은 경제성장 요소 외에 정책적·기술적·구조적 요인의 영향력이 적지 않다. 또한 선행연구 결과에 의하면 환경오염원별로 다양한 곡선이 나타나고 있다. 이러한 요인들을 고려하면 중국의 각 권역 및 지역별로 환경오염원 배출량 및 경제성장 간에는 다양한 EKC 곡선형태가 존재하는 것으로 사료된다. 본 연구의 time series 및 cross section 분석을 종합하면 향후 중국은 경제성장과 환경오염원 배출 간의 관계를 고려할 때 환경오염원 배출은 경제규모의 증대로 OECD국가 등 선진국들의 사례를 따라갈 가능성이 높다. 특히 다국적기업의 영향력에 주목할 필요가 있다. 이에 중국은 경제성장에 부응하는 법. 규제뿐 아니라 내. 외부요인을 고려한 권역 및 지역별 정책이 보다 강화될 것이고 특히 강력한 중앙정부의 정책추진과 함께 지방정부의 역할이 증대될 것이다. This paper consists of two parts including 1) Background of EKC(Environmental Kuznets Curve) theory and overview of previous oversea and Chinese studies 2) Empirically analyzing relationship between environmental pollution emissions and GDP per capita by regional groups in China. On these two parts, It can be understood about trends of Chinese environment protection policies, industries and economic policies from now on. It is important for China to effectively reduce the use of coals for reducing environment pollution emissions. and to overcome regional differences. Generally large economy scale and high income regions in China are not only low levels in emission but also effectively control with respect to EP(Environment Performance) Index and GDP to GDP ratio though increase emissions, that is, there exists technique effect and composition effect according to scale effect. In relationship between environment pollution emissions and GDP per capita, Each economy scale level of regions in China is still that of developing countries, the determinants of environment pollution emissions are influenced by not only policies, techniques and composition factors but also economy factor. Furthermore, there are various curve shapes by environment pollutions according to before empirical analysis. Consequently, Considering these factor, China will exist various EKC(Environmental Kuznets Curve) shapes between environment pollution emissions and GDP per capita. On summary of time series and cross section analysis, this paper can be concluded that China, considering relationship between economic growth and environment pollution, has high possibility to follow the case of OECD countries in the mid and long term future, especially focusing on the influences of multi-national companies. Accordingly, It can be forecasted that China will more strengthen not only regulations of laws but also regional policies considering in-external factors. Especially, with strongly pushing ahead central government policies, the roles of region governments will be increased.

정우식(Woo-Sik Jeong),정재영(Jae-Young Jeong),김찬규(Chan-Kyu Kim),정대인(Dae-In Jung),김경윤(Kyung-Yoon Kim) 한국콘텐츠학회 2011 한국콘텐츠학회논문지 Vol.11 No.3

본 연구는 PNF 중 스프린터 패턴 적용 시 하지의 근 활성도가 균형 능력에 미치는 영향을 알아보고자 다음과 같이 실시하였다. 편마비 환자 24명을 대조군과 실험군으로 나누어 실험군에 주 3회, 6주 동안 PNF의 상ㆍ하지 패턴의 결합인 스프린터 패턴(Splinter pattern)을 실시하였다. 하지 근활성도는 내ㆍ외측광근, 내ㆍ외측슬괵근, 외측비복근의 활동전위의 실효치 값을 분석하였다. 균형 능력 검사는 FICSIT-4, FSST, MTD-Balance system 이용하여 측정하였다. 운동 적용 방법에 따른 측정 시점에 대한 대조군과 실험군의 유의성 검정은 Two-way repeated measure ANOVA를 실시하였고, 각 측정 항목들 간의 상관관계를 알아보기 위하여 Pearson correlation으로 분석하였다. 그 결과 스프린터 패턴의 적용은 마비측 하지의 근 활성도를 증가시켜 정적 및 동적 균형능력을 향상시키는데 효과가 있었음을 확인할 수 있었다. 따라서 마비측 하지의 효율적 근동원을 위한 치료적 중재프로그램으로 적극적인 활용과 함께 다양한 운동 패턴들과 결합시켜 새로운 중재를 개발할 필요가 있을 것으로 생각된다. In this study, for examining an effect of lower limbs' muscle activity on balance capability when applying sprinter pattern among the PNF, the experiment was conducted as followed. Under the object of 24 people diagnosed by hemiplegia, they were divided into control group and experimental group and the experiment was conducted on the experimental group, three times per a week for six weeks. Experimental group received Sprinter pattern of combined PNF upper extremity and lower extremity pattern. For the lower limbs' muscle activity, effective values of Vastus medialisㆍlaterails, medial-lateral hamstrings, lateral gastrocnemius' action potential were analyzed. The balance ability tests was conducted with FICSIT-4, FSST and MTD-Balance system. For the significance test of control group and experimental group for measuring time by exercise application method, two-way repeated measure ANOVA was conducted and for the significance test among the groups by each measuring time, independent t-test was conducted. Also, for examining the correlation among the measuring item, pearson correlation was used for the analysis. As the result, the application of sprinter pattern increased muscle activity of lower limbs in paretic side and improve static and dynamic balance ability effectively. Therefore, it will be necessary to develop new intervention by combining active application of the therapeutic intervention program for lower limbs' effective muscle mobilizing in paretic side with various exercising patterns.
