The purpose of this study is to examine the effects of different group incentive type on performance under two types of interdependence in a task structure. One hundred twenty college and graduate students were recruited and asked to perform group typing task. Each typing groups organized three members. Participants were randomly assigned to one of four experimental conditions: equally-distributed incentive and differentially-distributed under two different task interdependence. In this study, the dependent variable was the number of correctly typed characters. We found the significant interaction effects between group incentive type and task interdependence. Specifically, under interdependent task, the work performance of participants in equally-distributed group incentive condition was higher than the performance in differentially-distributed group incentive condition.

As diversity has getting its significance, recent research on diversity has moved the focus from direct effects of diversity on performance to moderating effects between the two. In this paper, I analyzed the moderating effects of the innovative problem solving style and three types of interdependence (i.e., task, goal and outcome) on the relationship between diversity and performance. Empirical results using 75 project teams of R&D institute showed that the innovative problem solving style positively strengthened the effect of diversity on performance. All three types of interdependence also amplified the relationship between diversity and performance. I addressed theoretical and practical implications, and future research directions.

There are a variety of entities in natural language such as people, organizations, places, and products. These entities can have many various meanings. The ambiguity of entity is a very challenging task in the field of natural language processing. Entity Linking(EL) is the task of linking the entity in the text to the appropriate entity in the knowledge base. Pairwise based approach, which is a representative method for solving the EL, is a method of solving the EL by using the association between two entities in a sentence. This method considers only the interdependence between entities appearing in the same sentence, and thus has a limitation of global interdependence. In this paper, we developed an Entity2vec model that uses Word2vec based on knowledge base of RDF type in order to solve the EL. And we applied the algorithms using the generated model and ranked each entity. In this paper, to overcome the limitations of a pairwise approach, we devised a pairwise approach based on comprehensive interdependency and compared it.

The priority of requirement is important because the priority is a critical activity of release plan especially in software development which has an open market customer. Also, it is important for stakeholders to select a method and aspects to prioritize requirements. The selection is based on the organizational experience of a priority process, the process model of the product, goals and a type of products, and dependencies between requirements. But, the current researches considered only static dependency between requirements and did not suggest a systematic priority process. In addition, the current researches only suggest limited aspects to prioritize requirements, such as cost and value. Therefore, this paper proposes an adjustable priority process based on a priority model to select a method and aspects for the suitable priority for product and organization. Especially, this paper enhances the completeness of a release plan by a definition of static and dynamic dependency types between requirements. This paper suggests a priority model, which considers the dependencies between requirement and various viewpoint of software development. Based on the priority model, the paper suggests a systematic priority process to promote reasonable decisions to the priority and release plan of requirement.

We examine the interdependence of the major Asia-Pacific stock markets including S&P 500, FTSE 100, Kualar Lumpur Composite, Straits Times, Hang Seng, NIKKEI 225 and KOSPI 200 from October 4, 1995 to March 31,2000. The analysis employs the vector-auto-regression, Granger causality, impulse response function and variance decomposition using daily returns on the national stock market indices. The findings in this paper indicate that the volatilities of all countries has grown after IMF crisis, while there is no significance in cointegration test of both total period and sub-periods. This result implies that investors are able to get abnormal returns by investment diversification according to the portfolio theory. We find that while the effect from NIKKEI 225 to others is relatively weak, the interdependence from S&P 500 to other countries is strong. Also we find that the strong effect from Straits Times to Hang Seng exists. This study suggests that there is slight feedback relation between KOSPI 200 and Kualar Lumpur Composite, Straits Times, Hang Seng stock market.

본 논문은 의존 문법에 기반만 한국어의 구문 분석 시스템을 제안한다. 일반적으로 올바른 구둔 구조를 얻기 위해서 많은 가능한 구문 구조를 생성하고 이 중에서 가장 좋은 것을 선택하는 방법을 사용한다. 이를 위하여 가능한 모든 구문 분석 구조를 생성하는 기법을 제안하였다. 이것은 모든 가능한 구문 구조에 관한 정보를 응축한 자료 구조를 구축한 다음 여기에서 구문 트리를 하나씩 추출하도록 하였다. 이 과정에서 의존 문법이 만족하여야 하는 모든 기본적인 제약 조건을 만족하는 트리 만이 효과적으로 추출되는 기법을 제안하였다. 그 결과 생성되는 트리의 수를 줄이게 되어 효율적인 구문 분석을 달성할 수 있게 되었다. 추출된 많은 트리 중에서 하나를 선택하는 작업에서 상호 정보가 이용되었다. 본 논문에서는 이러한 상호 정보를 구문 분석 중의성 해소에 효과적으로 사용하는 기법을 제시하였다. 제안된 기법의 타당성을 입증하기 위하여 구문 분석 시스템을 개발하고 여러 문장에 대한 분석을 실험하였다.

본 논문에서는 데이터의존성과 벡터왜곡척도를 이용하여 개선된 칼라영상을 복호화하였다. 프랙탈 칼라영상의 복원방법은 Zhang과 Po의 벡터왜곡척도를 이용한 R, G, B 칼라 성분간의 상관관계를 고려하여 부호화한 압축파일을 사용하여 수렴될 복원영상을 독립적인 반복변환에 의해 수렴되는 영역과 데이터의존성을 갖는 영역으로 분류하여 데이터의존성 부분이 차지하는 만큼 복호화 과정에서 불필요한 계산량이 제거되었고, R 영역에서 검색한 데이터 의존영역을 G, B 영역에 그대로 사용하여 고속복호화가 가능하였다.

This paper analyzes the meaning of sustainability in sustainable development in the ecological ethics, and suggests the importance of ecological sustainability. In the discussion of ecological sustainability the relation between sustainability and change should be regarded as not conflictual but interactive. The concept 'ecological' in this context means network, and the concept 'sustainability' means the relationship between changing being(or beings) which constitutes ecological system and its unchanging being(or whole relation). So there are two axes of human and ecological system, and three elements namely network which means mutual dependence of human and nature, sustainability which means the maintenance of ecological relations, and responsibility which humans should take for the sustainability, in the ecological sustainability. The maintenance between being and relations of beings, changing sustainability, the priority of being to non-being, mutual interdependence on the basis of solidarity of beings are important values in the ecological sustainability.

The purpose of this study is to identify the characteristics of China's trade relationships with and dependency on the countries participating in the Belt and Road initiative and to present some implications. This study collected annual total imports, exports, and GDP data from the International Monetary Fund (IMF) on 198 countries and the National Bureau of Statistics of China (NBS) on 221 countries from 1995 to 2015. China's imports and exports have expanded considerably from the mid-1990s to the present, and China's dependence on imports and exports with the US and Japan has declined, while its dependence on the Middle East, South Africa, South America, and Southeast Asia has increased. China has a very high level of dependence on imports from and exports to the countries participating in the Belt and Road initiative, and as the Belt and Road project progresses, the mutual trade dependency between China and the other participating countries is expected to strengthen and expand.

계면면적 밀도는 two-fluid 모델에서 각 상 간의 상호작용에 영향을 주는 중요한 인자로서 이상유동 현상의 해석을 위하여는 이의 적절한 모델링이 필요하다. 계면면적 밀도의 모델링은 크게 상관식에 의존하는 방법론과 수송 방정식을 사용한 이론적인 접근방식으로 개발되어왔다. 후자는 시간적, 공간적으로 변하고 있는 동적 유동조건에 대하여 계면면적 밀도를 효과적으로 예측할 수 있는 방법론으로서 flow regime의 의존성을 줄이거나 없앨 수 있는 장점을 가진다. 계면면적 수송 방정식은 유체입자의 수밀도에 대한 수송 방정식의 통계적인 모델로부터 유도되며 입자들의 상호작용 및 상변화와 관련된 생성항을 포함하고 있다. 본 연구에서는 계면면적 밀도 수송 방정식 및 그 구성 모델들에 대한 연구현황을 정리하였다.
