This paper presents a new energy function reflecting the damping effect in multi-machine power systems. The Lyapunov direct method provides precise and rigorous theoretical backgrounds for stability analysis of nonlinear systems. Incorporating damping effects into accurate estimates of the domain of attraction, which is a minor but crucial point, has been attempted with long history to yield partial success for single machine systems. In this paper, the damping-reflected energy function presented in the previous work has been generalized for application to multi-machine systems. The generalized energy function is tested for the WSCC 9-bus system to show the semi-negativeness of its time derivative.

기술적인 발전에 따라 다양한 인터페이스가 등장하고 있다. 2D 일색이었던 인터페이스에 3D가 등장하기 시작했고 정적이던 화면 구성에 움직이는 요소들이 더해지고 있다. 움직임이 있는 자극들이 인터페이스에 쓰이면서 그 적절한 사용에 대해 알아볼 필요가 있다. 본 연구는 이런 움직임에 초점을 맞추고 있다. 특히 움직임의 여러 속성 중에서도 움직임에 스타일을 줄 수 있는 스쿼시 & 스트레치의 적용에 초점을 두고 있다. 본 연구는 움직임에 스쿼시 & 스트레치 기법의 적용이 움직임의 매력도와 감성, 주의에 미치는 영향을 알아보았다. 실험 1에서 참가자들은 스쿼시 & 스트레치 기법이 적용된 구와 적용되지 않은 구 모양 물체의 움직임을 보고 매력도와 움직임 관련 감성어휘를 평정하였다. 그 결과 스쿼시 & 스트레치 기법이 적용된 움직임을 더매력적으로 지각할 뿐만 아니라 해당 움직임을 더 밝고 적극적으로 지각하게 됨을 밝혔다. 실험 2는 스쿼시 & 스트레치가 적용된 구와 그렇지 않은 구를 화면에 동시에 제시하고, 참가자들이 변화를 탐지하는 반응시간을 측정했다. 그 결과 스쿼시 & 스트레치 기법이 적용된 움직임의 변화를 탐지하는 반응시간이 더 빨랐다. 이는 해당 움직임이 더 주의를 끌게 됨을 의미한다.

The exploratory purpose of this study was to investigate the Honsu trend and to examine the relationships between the Honsu, marriage exchange resources and marital satisfaction from general group and also explore the differences in Honsu expenditure between the general group and the aimed group. the explanatory purpose of this study was to prove the social meaning of the Honsu as a 'productive exchange resources' using Emerson's exchange network theory. The data was collected from 800 men and women of general group and 72 men and women of aimed group within 5 years of marital duration through the questionnaire method. Major findings of the study from the general group were as follows : in general group 1. The bridegroom group expended more Honsu than bride group. Bridegroom's primary expenditure item was house expenditure, and bride's primary one was newlywed life goods. 2. The bridegroom's Honsu were influenced positively by parents'SES, bridegroom & bride's education level and bride's parents'SES. Bride's Honsu were influenced positively by parents' SES and bridegroom & bride's education level. 3. Bridegroom's marital satisfaction were influenced positively by bride's marriage need, bridegroom's marriage need, bride's physical attraction and bridegroom & bride's education level. Bride's marital satisfaction were influenced positively by bride's marriage need, bridegroom's physical attraction, bridegroom & bride's education level, bridegroom's marriage need, bridegroom's future possibilities and bridegroom's Honsu. 4. The social meaning of the Honsu was a 'productive exchange resource'. 1. The bridegrooms of aimed group expended more housing expenditure and also Honsu than the brides but there's no statistically significant differences in Honsu expenditure between the bridegrooms and the brides of aimed group. 2. The bridegrooms of aimed group expended about 3 times more money for wedding present for spouse and abut 1.2 times more for Honsu than the bridegrooms of general group. The bride of aimed group expended about 4.6 times more money for general group. the bride of aimed group expended abut 4.6 times more money about 4 times more for housing expenditure and about 3 times more for total Honsu than the brides of general group.

점등 효과에 따른 동물플랑크톤 군집동태의 변화를 관찰하기 위하여 통영 바다목장 해역내 한국해양연구원 가두리 설치 지역에서 2004년 7월부터 2004년 8월까지 채집을 실시하였다. 점등 효과를 알아보기 위한 시료 채집은 야간에 점등구간에서 또한 자연상태의 동물플랑크톤 군집과 비교분석을 위하여 같은 시간에 인접 지역에서 점등에 영향을 받지 않는 장소를 선정하여 점등 시료와 동일한 방법으로 채집하여 비교 분석하였다. 조사기간 중 출현한 동물플랑크톤은 종 수준까지 동정한 21종을 포함하여 총 43개 분류군이었다. 불을 밝힌 점등구에서의 출현 분류군수는 비점등구에 비해 많은 개체수가 나타났으며, 두 구간에서의 동물플랑크톤 평균 출현량에서도 비점등구에 비해 점등구에서 약 $3\sim166$배 높은 출현량을 나타내었다. 본 연구에서 점등(불빛)으로 유집되는 동물플랑크톤 군집의 반응양상은 2개로 대별하여 특정지을 수 있는 것으로 나타났다. "A"그룹은 조사시기별 높은 출현 빈도를 나타낸 종들로 불빛에 명확한 양주광성(photo-positive)종들로 구성됨을 알 수 있었다. "B"그룹에 속하는 종들은 약간의 차이는 있으나, 대부분이 점등(불빛)에 소극적으로 반응하는 음주광성(photo-negative)으로 나타났다.

As the popularity of Korean drama and celebrities in China, Korean fashion is becoming increasingly popular in the Chinese market. Although the effect of Korean drama on Chinse consumers' attitudes toward Korean products are known, little research has been conducted to understand the mechanisms underlying the impact of Korean drama on the development of consumer attitudes. Thus, this study examines how Chinese consumers' exposure to Korean dramas has influenced their attitudes towards Korean fashion products. Applying the similarity-attraction theory, the study explores the roles Chinese consumers' perceived similarities in appearance and values with Korean characters in TV dramas plays in the process of attitude development. Data was collected via an online survey and the responses of 317 Chinese consumers in their twenties were used for data analysis. The results of structural equation modeling show that exposure to Korean dramas has a direct impact on Chinese consumers' perceived appearance similarity, perceived value similarity, image of Korean people, and attitudes toward Korean fashion products-results that support the theory of mere exposure. In addition, the analysis demonstrates that perceived appearance similarity positively influences the image of Koreans among Chinese people, which, in turn, influences attitudes toward Korean fashion products, supporting the similarity-attraction theory. However, the effect of perceived value similarity on attitude toward Korean fashion products was not significant. The study concludes by describing its practical implications for the Korean fashion industry and presenting ideas for future research.

China's cultural diplomacy is mostly understood as an endeavour to build and project soft power, which draws on three sources of 'culture, political values and foreign policy' according to Nye. This paper focuses on the debates about the vehicle and agents of China's cultural diplomacy. It starts with a theoretical discussion of the competing views in the Chinese context, and develops an argument that the vehicle of China's cultural diplomacy tries to project soft power on two wheels of culture and political values, to serve the purpose of reshaping China's image away from being the 'cultural other' and 'ideological other' respectively. However, the state-led approach to driving this vehicle is generating some side effects with its sponsorship, censorship and presence in the driver's seat. Then the paper analyses the inherent tensions existing in practice both between the two sources of building soft power and between the two means of doing so, attraction and persuasion, with empirical evidence through a comparative case study of the Confucius Institutes in the US and South Korea. The finding shows that China's attempt at reshaping its image as an Eastern cultural contestant is often disrupted by its authoritarian political values, and the state-led persuasion is often reducing China's cultural attraction. Following this, the paper finishes with some recommendations regarding evolving the cultural diplomacy approach from a vertical one that is government-centred to a horizontal one that is network-based with multiple agents, and localising its practice by engaging the target audiences as stakeholders.

This study aimed to explore the factors affecting the foreign direct investment (FDI) intentions of investors into Quang Ninh province, located in the north-eastern of Viet Nam. Researchers used two main methods, namely, Exploratory Factors Analysis (EFA) and the Structural Equation Model (SEM) based on partial least squares structural equation modeling (PLS SEM) to explore and measure the impact of factors affecting the investors' FDI intentions into Quang Ninh province. The empirical analysis used data from the survey of 206 domestic and foreign investors into Quang Ninh province, including representatives of the Board of Directors, members, and management representatives at the department level, with reliable tools (SPSS 26 and SmartPLS 3.0 software). The research results identified the following factors affecting investment into Quang Ninh: FDI attraction policies have the strongest impact on the investors' FDI intentions; it is followed by infrastructure, public services and human capital with strong effects on intentions of investors' FDI; and finally the standards of living that affects the investors' FDI intentions. There is also a positive relationship between all the factors and the investors' FDI intentions. Several recommendations are further suggested to enhance attraction of foreign direct investment into Quang Ninh province.
