For the escape from a maze, the cooperative method by robot swarm was proposed in this paper. The robots can freely move by collecting essential data and making a decision in the use of sensors; however, a central control system is required to organize all robots for the escape from the maze. The robots explore new mazes and then send the information to the system for analyzing and mapping the escaping route. Three issues were considered as follows for the effective escape by multiple robots from the mazes in this paper. In the first, the mazes began to divide and secondly, dead-ends should be blocked. Finally, after the first arrivals at the destination, a shortcut should be provided for rapid escaping from the maze. The parallel-escape algorithms were applied to the different size of mazes, so that robot swarm can effectively get away the mazes.

As construction duration significantly influences the performance and the success of construction projects, it is necessary to appropriately manage the impact factors affecting construction duration. Recently, interest in the construction industry has been rising due to the recent change in the construction legal system, and the competition among the construction companies on construction time. However, the impact factors are extremely diverse. The existing productivity data on impact factors is not sufficient to properly identify the impact factor and measure the productivity from various perspectives, such as subcontractor, time, crew, work and so on. In this respect, a multidimensional analysis by a data warehouse is very helpful in order to view the manner in which productivity is affected by impact factors from various perspectives. Therefore, this research proposes a method that effectively takes the diverse productivity data of impact factors, and generates a multidimensional analysis. Decision tree analysis, a data mining technique, is also applied in this research in order to supply construction managers with appropriate productivity data on impact factors during the construction management process.

Today the distribution of characters in the consumer market based on digital smart phones is expanding, and the characters themselves are sold with independent merchandise, also various application researches about character are being activated. However, depending on the style of worker 's work on the design process of Korea and China regarding characters, there are differences in design characteristics and the diversity of work. In this study, we attempted to investigate the implications of these designers on the development of creative character design through in-depth research and experiment. Therefore, previous researches of cognitive science were investigated and cognitive experiments were conducted on design process for experts. For this research experiment, the initial sketch stage in the character work of Korea and China was recorded by the method of the designer by the subject through the protocol analysis method which is the qualitative research method. We coded the collected language based on this recording experiment and analyzed the problem behavior. We examined how the cognitive acts are done by the designer to develop the characters. The behavior characteristics and the accidental characteristics. The differences of the behavioral characteristics and the accidental characteristics in each step of the character design process were identified. Through these cognitive experiments, we could examine the behavior analysis of the design thinking process in Korea and China. In the field of design practice, we can set the direction of the design work process of the two countries and help us to produce creative and individual results. I think. These studies are expected to contribute to practical application of product marketing and new cooperation development methods in terms of activation of character industry in the future.

Local accounting system used by UNIX-like operating system provides the accounting information of processes that are in single host. But it is impossible for this local accounting system to record the total resource consumption data of all processes for doing the same job simultaneously. In this paper, we implement accounting system to measure and manage resource usage for MPI(Message Passing Interface) job in the clustering environment. We designed and implemented the accounting system which measure resource usage of each process runs on a cluster node and record the interconnection information of the entire set of processes across network. Also we implemented accounting system which collect the resource usage data of process in the local accounting system and generate the job-level accounting information. Finally, to evaluate the resource consumption data measured by this accounting system we compare with the data collected by local scheduler that widely used in large scale clustering environment.

The roles and needs of contents are increasing moving toward sensitivities and culture in terms of key values in the 21st century. The cartoon is evaluated in invaluable as the original contents. Moreover, the size of these industries and employees are extending. Regardless of the quantitative expansion, however, it is real situation that is delaying in the disciplinary development and that is scare in partnership with industries. It is needs to develop the textbook and its' systemizing, standardization of cartoon language, and cartoon dictionary development. Using the cartoon language widely, it requires universality, simultaneously it needs a times and exact definition in advance. The study and standardization work of cartoon terms in base endure the industry development and disciplinary research which enhance the efficiency between the two sectors.

1966년에 국제학술연합회의(ICSU)는 과학기술데이터위원회(CODATA)를 조직하였는데 이는 세계적으로 수치데이터 수집에 관한 조정(調整)을 꾀하고 유도해주며 해당 사기관, 정부기관 및 정부간기관의 데이터 수집을 적극 지원해 주기 위한 것이었다. 현재 위원회는 8개국으로부터의 회원과 10개의 국제연맹을 가지고 있으며 이들은 CODATA의 목적을 달성하기 위하여 내부적인 수법을 사용해 오고 있고, 또한 각국의 관련단체들은 비공식적인 전달수단을 통하여 서로 연결되어져 있다. CODATA의 중앙국은 원래 워싱턴에 있었으나, 지금은 독일의 프랑크푸르트에 위치하고 있으며, 중요한 데이터평가 및 수집센터의 간행물을 분석한 요약판이 곧 발행될 것이다. 그밖에 특수한 문제를 해결하기 위하여 기본상수, 수치데이터처리를 위한 전자계산기의 응용, 수집가가 사용하는 중요입력데이터의 표준 등에 관한 작업반이 설치되었다. 한편, 세계적으로 수치데이터 수집가들간의 협력이 활발히 이루어지고 있다.

In this paper, we designed and implemented the general-purpose document repository manager for the ebXML-based e-business framework that support the rapid translation of various types of documents and provide the flexibility corresponding to the framework changes. Also, we automated the manually-processed e-business document translation process by designing the adaptor module for the interoperability of legacy systems. In the regards, our designed general purpose document manager makes it possible to integrate the existing e-commerce systems that are operated on the heterogeneous frameworks, and can be used on global e-business solution.

21세기 정보화시대를 몇 개월 앞두고 전자상거래가 급팽창함에 따라, 인터넷 전자상거래는 이제 선택의 문제가 아니라, 기업이나 국가의 경쟁력 확보 및 생존을 위한 필수적인 전략으로 인식되고 있다. 최근 선진국들을 비롯하여 OECD 등 국제기구에서 인터넷 전자상거래에 관한 국제적 논의와 규범화 작업이 진행되고 있다. 그러므로 우리 나라도 이러한 인터넷 전자상거래시대에 대비한 국제경쟁력을 확보 하기 위해 정부와 민간의 협력을 기반으로 한 범국가적 대용방안의 수립이 필요한 시점에 와 있다. 이러한 상황하에서, 본 연구는 인터넷 전자상거래의 영향과 현황을 파악한 후, 이에 대한 국제규범화 동향과 주요 과제를 분석하여 우리 나라의 대응방안을 제시하고자 한다.
