윤성환 ( Seong Hwan Yoon ) 현대중국학회 2011 現代中國硏究 Vol.12 No.2

본 연구는 최근 상하이 엑스포 참가로 한국의 국가이미지와 기업이미지가 이전보다 개선되었을 것이라는 데 중점을 두고, ‘한국관’, ‘한국기업 연합관’, ‘서울관’ 등을 참관한 중국 소비자들을 대상으로 이러한 두 요인이 한국제품 선택에 어떠한 영향을 미치는가를 분석하는 데 주요 연구목적이 있다. 분석결과, 국가이미지와 기업이미지는 모두 부분적으로 중국 소비자들의 한국제품 선택에 영향을 미치는 것으로 나타났으며, 기업이미지의 영향이 국가이미지보다 상대적으로 더 큰 것으로 나타났다. 따라서 중국에 진출한 한국기업은 기업이미지 제고에 역점을 두어야 할 것이다. 끝으로, 본 연구에서는 이러한 분석결과를 토대로 한국 정부와 기업에 대하여 성공적인 중국 현지경영을 위한 국가 및 기업이미지 제고와 관련된 전략적 시사점을 제공하고 있다. This thesis focused the Korean country image and cooperate image are assumed, due to the participation of Shanghai Expo, to have been much enhanced. The main purpose of this study is to analyze how the enhanced images so assumed can effect Chinese customers`-who visited Republic of Korea Pavilion, Republic of Korea business Pavilion and Seoul Pavilion-selection of Korean products. The analysis resulted in telling that the cooperate image worked better than the country image in influencing Chinese customer`s selection of Korean products although each image has its own influence. Therefore, Korean cooperates in the China have to place greater emphasis on improving their image. Finally, this may provide some strategic suggestions with regards to reconsidering Korean government and cooperates for Chinese local businesses in China to be successful.

The effects of varying flame surface area due to hydrodynamic instability on secondary acoustic instability in downward propagating flames were studied experimentally. To quantitatively control hydrodynamic instability, one of intrinsic combustion instabilities, CO₂ laser irradiation technique was adopted. Because of the increase in flame surface area of the flame surface area artificially, the transition from primary acoustic instability to secondary acoustics instability occurred, and the occurrence time of secondary acoustic field became relatively shorter when the rate of variation in flame surface area was increased. However, the rate of variation in flame surface area and the wave number of corrugated structure were found to have little effect on the growth mechanism of secondary acoustic instability.

As we have seen, the daedaero(大對盧) in late Goguryeo was the highest position of an official rank and government office. However, unlike the conventional understanding, the daedaero was multiple as official rank. It was told the daein(大人) or tojol(吐?) to distinguish with a government office daedaero in the middle of the 7th century. Also, numerous daein"s could take office in as government office daedaero. It was elected through the meeting of daein"s(大人會議). The meeting of daein"s was composed of the daein"s, discussed the election and re-election of a daedaero. This conference, which is run by council system of all members, certified the daedaero as representatives of daein society. This fact indicates that Yeon Taejo(淵太祚), the father of Yeon Kaesomoon(淵蓋蘇文), was served as official rank the daedaero(=daein, tojol) and as government office daedaero. Yeon Kaesomoon inherited the daein from his father. Nobilities" counsel system in late Goguryeo operated the meeting of daein"s and the council of five offices(五官會議) as conference system. The meeting of daein"s tuned political dynamics inter nobilities. While the council of five offices(五官會議) was to administrate state affairs. Dual operation of the conference system of nobilities was to prevent possibility that power struggle of nobilities spread over affairs of state. Also, king could not intervene the meeting of daein"s. king do not carry out as higher power in that case. And the existence of the meeting of daein"s make some nobilities monopolizing the positions as government office daedaero. Therefore, the meeting of daein"s was also in a sense privileged authority.

은행의 서비스품질이 고객만족, 고객신뢰 및 고객충성도에 미치는 영향: 중국진출 국내은행을 중심으로

윤성환 ( Seong Hwan Yoon ) 한국외국어대학교 중국연구소 2010 中國硏究 Vol.50 No.-

China`s recent financial market opening has brought an increasing number of Korean and foreign banks into China, and, as a result, the competition has become intense among those banks to attract local customers. This study deals with the relationship between service quality and customer satisfaction, customer trust and loyalty observed by Chinese customers who had used banking services provided by Korean banks operating in China. The empirical analysis shows that three kinds of service quality(process quality, outcome quality, service environment quality) have a positive effect on customer satisfaction and trust. However, the analysis also shows that process quality does not play a significant role in gaining customer confidence. Furthermore, customer satisfaction positively affects customer trust in terms of the relationship between customer satisfaction and customer trust, and both of them also have a positive effect on customer loyalty. This study also provides several strategic suggestions concerning the service quality of Korean banks in China.

자료 포락 분석 방법을 이용한 객관적 건물 에너지 성능 평가

Objective energy performance assessment of buildings is crucial for building stakeholders’ rational decision making. One of the most popular building energy performance measures is Energy Use Intensity (EUI, kwh/m2.yr). This has been widely used since it is straightforward, simple and easy to understand. However, it has a severe drawback that it only shows the number of consumed energy per unit floor area and can’t represent objective energy performance of a building. In other words, EUI does not deliver how well a building serves occupants and provides satisfactory services (e.g. thermal comfort). It is often misinterpreted in a way that the less EUI, the better building energy performance is. In this paper, a Data Envelopment Analysis (DEA) was applied to assess objective building energy performance. The DEA quantifies performance of a given system when multiple inputs and outputs are given. The DEA is a data-oriented and non-parametric method. Thus, it does not require any energy model and can consider multivariate inputs/outputs simultaneously. For the study, a number of virtual buildings were generated out of Monte-Carlo sampling and then simulated using EnergyPlus to derive a data set. Energy consumption was used as an input and building service levels (e.g. occupancy density [people/m2], operation time [hrs/yr], thermal comfort [PPD]) were used as outputs. It is shown that the DEA is a more objective and rational performance assessment method than the EUI, and can be a good alternative for building energy performance evaluation.

윤성환 ( Seong Hwan Yoon ) 慶熙大學校 社會科學硏究院 2010 社會科學硏究 Vol.36 No.1

본 연구는 최근 중국 농촌시장의 중요성이 증대되고 있는 시점에서 국가이미지와 기능적 속성 및 브랜드개성이 중국 농촌 소비자들의 한국제품 선택에 어떠한 영향을 미치는지를 분석하는데 그 목적이 있으며, 이러한 분석결과를 토대로 한국기업의 대중국 마케팅 전략을 도출하고자 한다. 실증분석 결과, 3가지 요인은 정도의 차이는 있지만 모두 중국 농촌 소비자들의 한국제품 선택에 유의한 영향을 미치는 것으로 나타났다. 이중 기능적 속성의 영향을 가장 많이 받는 것으로 나타났으며 브랜드개성 역시 상징적 속성으로 중국 농촌 소비자들의 한국제품 선택에 중요한 역할을 하고 있음이 밝혀졌다. 본 연구결과가 시사하는 바는 한국기업들이 중국 농촌시장으로 진출함에 있어 제품의 기능적 속성뿐만 아니라 독특한 브랜드 개발의 필요성을 암시하는데 이러한 브랜드 이미지가 한국의 국가이미지를 잘 나타낼 수 있을 때 중국 농촌 소비자들의 한국 브랜드에 대한 충성도는 더욱 높아질 것이다. This study researches directly and indirectly how country image, product attributes and brand personality, influence the rural Chinese consumer's Korean Products selection and reports the strategic implications of its findings. From the rural Chinese consumers viewpoints, the researcher seeks to determine how country image, product attributes and brand personality influence Korean Products selection. The strategic implications of this study is as follows: brand personality presents as a symbolic aspect that accounts for a significant amount of differences in the rural Chinese consumer's Korean Products selection. Throughout this study, it can be acutely recognized that brand personality in relation to its symbolic aspect has an important influence on the rural Chinese consumer s Korean Products selection. This study suggests the necessity of effort to develop representative brands with a unique personality in connection with a country image. As, brand personality adds brand identity to reliability and makes for a stronger brand in Chinese markets.

윤성환 ( Seong-hwan Yoon ) 한국통상정보학회 2017 통상정보연구 Vol.19 No.4

최근 중국에 진출한 한국기업들은 제품과 직접적으로 관련된 마케팅활동 이외에도 기업이미지 제고를 위한 수단으로 CSR활동과 기업광고를 활발히 수행하고 있다. 이러한 맥락에서 본 논문에서는 중국 현지 소비자들을 대상으로 중국에 진출한 주요 한국기업들의 CSR활동과 기업광고가 기업이미지에 어떠한 영향을 미치는가를 분석함과 동시에 기업이미지와 기업-소비자 동일시, 한국제품에 대한 평가와 중국 소비자의 행위적 반응 간의 구조적 관계에 대하여 파악하고 있다. 이를 위해 우선 이론적 논의 및 선행연구를 바탕으로 5개의 가설을 설정하고 이 가설들을 종합하여 이론적 연구모형을 구축하였다. 그리고 이 연구모형을 검증하기 위해 중국내 주요 대학의 MBA학생들을 대상으로 한 설문조사를 진행하였다. 실증분석 결과를 요약하면 다음과 같다. 첫째, CSR활동과 기업광고는 기업이미지에 정(+)의 영향을 미치는 것으로 밝혀졌다. 둘째, 기업이미지는 기업-소비자 동일시에, 기업-소비자 동일시는 제품 평가에, 제품에 대한 긍정적인 평가는 중국현지 소비자들의 행위적 반응에 모두 정(+)의 영향을 미치는 것으로 밝혀졌다. 이러한 연구결과는 향후 중국에 기진출한 한국기업들이 중국 소비자들에 대하여 호의적인 기업이미지를 심어주며 소비자와의 우호적인 관계를 지속적으로 유지하기 위하여 활발한 CSR활동과 기업광고활동을 수행해야 할 필요성이 있음을 시사한다. Korean companies currently operating in China have made active efforts to undertake corporate social responsibility activities and corporate advertising to improve their image, as well as marketing activities directly related to their products. In this context, this study aims to analyze how corporate social responsibility activities and corporate advertising influence a company's image from the perspective of Chinese consumers. This study also analyzes corporate image, consumer-company identification, and the structural relationship between the consumers' behavioral responses and their evaluation of Korean products. Based on theoretical discussions and previous studies, the study tests five research hypotheses for the development of a theoretical research model. In order to empirically test the research model, data were collected by enlisting and observing MBA students from major universities in China. The results obtained by actual analysis are as follows. First, corporate social responsibility activities and corporate advertising were found to be positively influential on corporate image. Second, corporate image is positively influential on consumer-company identification. The consumer-company identification of Chinese consumers' evaluation of Korean products, and positive evaluation of Korean products in turn induce positive influences on Chinese consumers' behavioral responses. These results suggest that the Korean companies already established in China not only need to enhance a positive corporate image but also have to make efforts to undertake corporate social responsibility activities and corporate advertising activities in order to improve their continuous and long-term relationship with Chinese consumers.
