This paper introduces the public-oriented e-Hub construction for strategic alliances in the B2B virtual community. The public-oriented e-Hub can link with all participating Internet firms on the basis of their business models, and consequently help them share their core competence, management resources, and so on. Based upon this perspective, this paper presents the procedures corresponding with social network analysis for strategic alliances of small and medium internet firms. In addition, this paper tries to analyze the relationships among degree of competition, potential of strategic alliance, and financial performance. The results show that the firms with more easily accepting various strategic alliances make higher financial performance under more competitive environment. This suggests that strategic alliances through the public-oriented e-Hub in the B2B virtual community provide the internet firms with various opportunities.

This plan is for a different type of welfare facilities devised by analyzing problems with existing welfare centers and focusing on connection with residents and link between culture and welfare and among generations. In terms of re-development plan of Youngsun-2-dong, Youngdo-gu, Busan and the neighborhood under this plan, Youngsun-dong, Youngdo-gu is one of the densely populated districts of the aged, with lower growth rate and poor housing and welfare facilities. However, the district has a blessed natural environment and historical site of cultural relics of the Neolithic Age as well as growth potential as a logistics center with broader network of roads linking with Bukhang Bridge when Namhang Bridge construction is complete, showing the aspiration for change toward hi-tech maritime city in the 21st century of Youngdo-gu. This plan is expected to promote unity between the old and children, protection from social marginalization, and re-socialization education and set the stage for participation and solidarity of residents in the community.

This paper suggests a balanced scorecard (BSC) framework for measuring and evaluating the performance of knowledge workers in professional service firms(PSFs) which are typical knowldege-based organizations. As a strategic learning system, the balanced scorecard allows business leaders to drive and modify their business strategies based on the balanced measurement of key performance indicators(KPIs), which are basically divided into four domains such as financial achievement, customer orientation, internal business process, and innovation and learning. Conducting a focused case study on performance evaluation of knowledge workers from a balanced viewpoint, we could evaluate their competency and potential in more comprehensive manner. We also employ the analytic hierarchy process (AHP) approach for derive relative weights of key performance indicators and link it to a spreadsheet model for rating the individual performance of knowledge workers in a systematic way.

Non-Annex I parties announced the voluntary emission reduction targets including the U.S. in the conference of party. NAMAs would be focused to solve the negotiation clue for the post-kyoto regime. Since the country would not be involved in Annex I parties, the voluntary carbon market would be created for the greenhouse gas reduction targets. According to Bali Roadmap, voluntary carbon market should be constructed by the MRV manners since this country does not belong to Annex I parties. Carbon point system would be proposed by the ways of the international voluntary emission reduction credit. The voluntary carbon market should involve the potential GHG reduction credit and link with the ETS in the country. This study proposed the way of linkage between ETS and voluntary carbon market including the carbon-point system.

The development of food science in the near future probably depends on the advance in functional food science. Actually, a number of substances and products with potential for disease risk reduction rather than simply for health maintenance have been investigated for their body-modulating functions. Some of them have been applied in practice to the industrialization of functional foods in terms of foods for health uses. Health is becoming a more important aspect of food. Consumers increasingly see the link between food and health, thus generating growing levels of consumer interest in more actively managing their diets and, by implication, their health. there is demand from consumers and strong manufacturer push towards the development of food as medicine. Pharmaceutical companies are currently focused on the medical aspects of food as medicine, but it is expected that there will be an increase in the rate of active ingredients for lifestyle application.

Colangiocarcinoma (CCA) is a progressively fatal disease which generally occurs due to malignant transformation of hepatic biliary cholangiocytes. The incidence of CCA has been increasing worldwide and there is an urgent requirement for effective diagnosis and treatment strategies against this devastating disease. Different factors including liver-fluke infestation, viral hepatitis, exogenous nitrosamine-mediated DNA damage, and chronic inflammation have been linked to CCA genesis. However, the risk factors and underlying complex mechanisms leading to development of CCA are not sufficiently understood to devise an effective targeted treatment therapy. In this review, we summarize currently known epidemiological and pathological aspects of the disease and briefly describe various potential biomarkers and experimental anticancer phytochemicals related to CCA research. In addition, we also sum up recent findings that link chronic inflammation of hepatic biliary cholangiocytes with CCA. The collective information concisely presented in this article would provide useful insights into the current understanding of this cancer.

This paper proposes a second-order implicit constraint enforcement method which yields enhanced controllability compared to a first-order implicit constraints enforcement method. Although the proposed method requires solving a linear system twice, it yields superior accuracy from the constraints error perspective and guarantees the precise and natural movement of objects, in contrast to the first-order method. Thus, the proposed method is the most suitable for exact prediction simulations. This paper describes the numerical formulation of second-order implicit constraints enforcement. To prove its superiority, the proposed method is compared with the firstorder method using a simple two-link simulation. In this paper, there is a reasonable discussion about the comparison of constraints error and the analysis of dynamic behavior using kinetic energy and potential energy.

Cable and membrane structures can be classified as a unstable structure in the view point of shape determination process. An unstable stucture at the initial state generally cannot take a role as the resistance for the external force. Therefore, there should be a stabilizing process to get the stable state of a structure and it is necessary to visualize the shape finding from unstable state to stable state. In this paper, a numerical method of stabilizing procedure for the link structures is presented. The structures are assumed to have rigid movements and thus only changing of the topology of member is considered during the analysis. The generalized inverse matrix and the principle of minimum potential energy are used in the process. Illustrative examples are presented and the results show good convergence.

A global model of simulator sickness is outlined that suggests the sequence of events leading to the development of simulator aftereffects. The model attempts to link coupling effects of illusory self-motion(vection) and compensatory head sway to the origin of simulator sickness. A pilot study was conducted in support of a rescarch program that will investigate the proposed model. Seven males and four females participated in a 5-min scssion in a fixed-base automobile simulator. Due to restricted sample size, descriptive statistics are presented for measures of simulator sickness, lateral sway velocity (Y-velocity), driving performance, control inpuls, and vection ratings. Although potential trends are discussed, no statistical conclusions can be drawn. Measurement issures for te next phase of reasearch mclude increasing the sensitivity of vection ratings, and examination of the timecourse got development of compensatory sway.
