The study investigates the challenge of knowledge maintenance in the KMSs. Knowledge pieces are the embodiment of structures in an organization and need to be modified tuned to environmental change over time. Since the change of knowledge in the KMS is not made automatically, it requires user's active participation which is called maintenance action. This study shows that users are not voluntary in taking maintenance action with empirical data based upon knowledge pieces that are already established in the KMS. This article shows that the intention of maintaining KMS is negatively influenced by KM-related culture, organizational culture and the authority of knowledge piece rather than the organizational demography. An organizational culture has an influence directly upon the intention of maintaining knowledge but influence upon KM-related culture or the authority of knowledge piece, the influence indirectly related to the intention of maintaining knowledge. It can be argued that the organizational demography have only meager influence upon the intention of maintaining knowledge only by KM-related culture. This research has the implication that what factors are to be considered in maintaining knowledge pieces over time for the organization managers.

Korean civil and environmental organizations had selected and announced ‘The top ten pieces of news in the environmental field of the year’ on Dec. 2, 1999. This study investigated the possibilities that these could be used as subject matters of environmental curriculum and infused into the environmental textbook of secondary schools, referring to documents and internet materials. The top ten pieces of environmental news could be clarified as controversial topics. The locality was analyzed that 2 pieces occurred mainly in a specific area, 4 pieces in several areas and 4 pieces around all over the country. Most of them had the opposing partners as the federal and local governmental vs. civil organizations and people. Each of them could be used as subject matters for 7 to 13 contents domains of the 6th and 7th Korean environmental curriculum. The knowledge of most of them had related counterpart concepts to be infused into the ‘Environmental Science’textbook for the high school students. The results suggested that more concerns and efforts are needed to deal and use these controversial issues as real world problems of Korea in the environmental education practices

A simulated realistic virtual environment is inhabited by autonomous cyber-humans who play the roles of agents in events. A key element, which enables this realism, is the historical context formed by time and space. A knowledge-representation scheme, composed of both spatial and temporal aspects needed by the agent to respond to dynamically changing situations, is essential for the design of a realistic virtual agent. In this work, spatial and temporal aspects of dynamic situations in the virtual environment have been formalized as a key component of our knowledge-representation scheme. This scheme provides a mathematical framework to construct realistic virtual situations that change with time, and background knowledge for agents in the simulated environment to deduce new pieces of information and plan against changing situations.

In this study, we will present a knowledge-based consulting system, called THYCONS, for diagnosing thyroid disorders. It has been developed to make the knowledge and expertise of the human expert more widely available, therefore achieving a high-quality diagnosis. Frames will be used to represent the medical knowledge of thyroid disorders, and several rules are attached in each slot of a frame. The uncertainty of diagnostic processes is manipulated by the subjective Bayesian method under the assumption that the pieces of evidence are conditionally independent. Searching for the group of diagnostic tests to be carried out and their optimum sequences will be established in order to infer a more correct diagnosis on the basis of maximum information gain with cost and time restrictions. Additionally. differential diagnosis will be carried out based on the information gained.

This study was conducted to identify actual dental care status, levels of knowledge, attitudes, and behaviors about dental health, and dental health conditions in elementary students; and examine the relationships between the levels of knowledge, attitudes, behaviors, and dental health conditions for 427 students in their sixth grades from six elementary schools in Pusan area from November 1st to December 5th, 2002. The data was collected through a structured study questionnaire and through dental checkups by dentists and was analyzed into frequency, percentage, mean, standard deviation, t-test, one-way ANOVA and Pearson's correlation analysis using SPSS program. The main results of this study were summarized as follows： 1) The levels of knowledge, attitudes, behaviors about dental health was found to be high as mean score 18.75 points (64.7％) in knowledge, 17.86 points (59.5％) in attitudes, and 31.64 points (67.3％) in behaviors. Therefore they were found to care a lot about their dental health. The indices of dental health conditions were found to be low as mean score 0.87 pieces (3.1％) of treated teeth, 1.27 pieces (4.5％) of teeth to be treated, 7.64％ of the DMFT rate and 0.43 points (7.2％) of the simplified oral hygiene index. Therefore their condition of dental health was found to be very clean. 2) The relationships among the knowledge, attitudes, and behaviors about dental health showed a weak level of positive correlations. Among the conditions of dental health, treated teeth and the DMFT rate showed a moderate level of positive correlation； and treated teeth and the simplified oral hygiene index showed weak level of positive correlation. 3) The condition of dental health of the subjects of this study was found to be good and dental care was properly done when there was participation of parents and school health educators in dental care. It tells us that dental education is required not only for children but also for their parents. As there were significant correlations between knowledge, attitudes, and behaviors about children's dental heath, school health educators should encourage students to have continuous dental care habits for lifelong dental health with repetitive education, rather than to deliver simple knowledge to students during dental health education.

The purpose of this article is to present the potential of balangandãs as a documentary source for intersectional studies of gender and slavery, from the analysis of formal and symbolic aspects of the museum objects in the Museu Nacional Nacional (MHN) and Museu Carlos Costa Pinto (MCCP). Balangandãs are a type of creole jewelry, made in gold or silver and used in Brazil since the 18th century by black women - women who worked, especially in the commercialization of foodstuffs in large urban centers. They are described in printed sources and engravings, and preserved in some museum institutions. In the study, the meanings attributed to the object over the centuries are observed: jewelry, amulet, peculium, document, travel memory and heritage. As a result, the article seeks to highlight the objects as a historical and documentary source, verifying similarities between the pieces musealized at the MHN and at the MCCP, also emphasizing the documental power of the pieces produced today.

A lot of pieces of iron plate are used to build a ship. The states of cutting surface of iron are however bended or ununiformly cuttled by cutting machine. These may cause bad Quality of painting, and shorter lifetime of iron by rust. In this paper, a new approach of grinding force control method which teaching of robot is not required is proposed to avoid long preparation time of robot and to improve the productivity. The way used in this paper is just like a blind man works through the road with stick only.

Exchange of information is essential to the process of innovation such as product development. However, in many cases innovation fails because of a lack of knowledge sharing among parties concerned, even if parties individually have pieces of useful knowledge and skills. Besides physical factors like communication costs, the possibility of opportunistic behavior by parties like stealing ideas can discourage information exchange. This paper introduces a model to analyze incentives of information exchange. The model is a game by two players who alternately opt to offer information to the partner. It is suggested that information exchange can stop before reaching the efficient level. In order to attain the efficient information exchange, expectation of mutual benefit and absence of opportunistic motives in both players are needed. Methods for promoting information exchange include modifying payoff structure to meet the condition of information exchange. The fluidity of partnership may increase a variety of information exchange partners, but discourage building trust between partners which promotes information exchange.

With the advent of the Fourth Industrial Revolution and the era of big data, the ability to handle data has become essential. This has heightened the importance and necessity of data literacy competencies. The purpose of this study is to propose a framework for data literacy competencies. To achieve this goal, data literacy frameworks from eight countries and twelve pieces of literature on data literacy competencies were analyzed and synthesized, resulting in five categories and twenty-three competencies. The five categories are: data understanding and ethics, data collection and management, data analysis and evaluation, data utilization, and data governance and systems. It is hoped that the data literacy competency framework proposed in this study will serve as a foundational resource for policies, curricula, and the enhancement of individual data literacy competencies.
