Implementation of semi-public management system of intra-city bus achieve excellent results but there are some side effects like increase of the fatal traffic accidents. This study tries to develop decision making model of measures of reducing traffic accidents following implementation of semi-public management system of intra-city bus. And survey with traffic experts and analytic hierarchy process are used for data survey and analysis. Quantitative measures and qualitative measures are suggested as high assessment items of AHP. Quantitative measures of low assessment items composed of a raise in the number of bus and safety device installation, facility supplement of bus stop, supplement of pedestrian protection facility, traffic safety assessment and supplement. Qualitative measures composed of system organization, redesign bus route, reinforcement of education, campaign and enforcement. The results of this study are as follows. First, the result turns out more weights are calculated on quantitative measures than on qualitative measures. Second, It is turned out in order of facility supplement of bus stop and traffic safety assessment and supplement as the quantitative measures. Third, as qualitative measures, system organization and redesign bus route are in the order. The results of this study are considered to be a basic data which can be referred if measures on the decrease of traffic accident are established and implemented in other cities and provinces.

Successful Electronic Commerce(EC) requires not only a transformation of the supply chain but a redesign of organizational processes as well. Just as the organizations in a supply chain must cooperate with each other to achieve a collective goal, so too do the departments and groups that comprise an organization depend on each other to achieve the organization's goals. A lack of coordination at either of these levels can result in poor performance and high coordination costs. In addition, changes in inter-organizational dependencies can affect the dependencies within the affected organizations. The lack of coordination across two levels results in a transition gap in transforming the inter-organizational design to the intro-organizational design in EC deployments. The purpose of this research is to develop a modeling method for coordination, managing the linkage between inter- and intra-organizations in EC deployments. The method was applied to the EC development project of a cable TV home-shopping company. The coordination approach enabled us to manage dependencies among the coordination elements and identify the effect of a change on other elements, which became the basis for effective EC deployments. We will discuss the method and compare it with other dependency management methods.

Objective : This study was designed to identify the effects on the time usage and quality of life of seniors with stroke by applying lifestyle redesign programs on the theoretical basis of the Occupational Balance. Method : A pretest-posttest control group design was conducted for a total of 40 stroke elderly people living in nursing homes(20 experimental and 20 control groups). Prior assessment was conducted for two weeks before the application of the lifestyle redesign program. For the next 10 weeks, the lifestyle redesign program was applied seven times a week. After that, a week of post-evaluation was conducted. The time usage for the subjects was analyzed by Life Time Survey Table of the National Statistical Office(2009) and life quality for them was analyzed by World Health Organization Quality of Life-BRIEF (WHOQOL-BRIEF). Result : The comparison of time usage before and after application of the program demonstrated that for the experimental group, rest and sleep(t=-4.89, p<.001), and leisure(t=-4.67, p<.00b1) showed significant differences. In addition, intergroup comparison results showed that there were also significant differences in rest and sleep(t=-2.24, p<.01) and leisure(t=3.57, p<.01). The comparison of life quality showed a significant difference between two groups(t=6.80, p<.001). If you look at the sub-area of quality of life, a significant difference was identified in physical health(t=6.08, p<.001), psychological health(t=5.21, p<.001), living environment area(t=3.60, p<.01). Conclusion : Lifestyle redesign program actually reduced the time usage for rest and sleep for elderly with stroke living in nursing homes, and increased the time for participating in leisure life resulting in improved quality of life.

Due to the increasing complexity to handle conflicts and interruptions caused by resource failures and rush orders, shop control is obliged to redesign its organization according to the changing demands of the manufacturing control. These demands are leading to the development of decentralization and gradually to their permanent optimization. As a result, a powerful modeling method which can be adapted efficiently is required. The use of agent theory enables specific modeling of the relevant shop planning activities. The planning activities are modeled in a so-called activity modeling through the definition of three classes of agents; Plan Agent, Manufacturing System Agent and Control Agent as well as the description of the cooperative relationship among these agents. On the basis of the activity model the agent-based shop control method is developed which emphasizes the distributed problem-solving and the cooperation with relevant agents.

Some simulation tools have been developed to support business process reengineering. These tools can be used to not only analyze an as-is model of the existing process but also assess the potential value and feasibility of to-be models. But most of them are restricted to analyzing and redesign of the workflow only. Little attention is paid to the organization of people and their roles. This paper Presents a new methodology for business process simulation modeling and analysis. The methodology is based on the concepts of roles and customer-supplier chains. So the proposed methodology allows for tracking people and their roles affected by reengineering the business process. It enables one to analyze and evaluate not only workflow, but roles that are part of the flow. This paper developed a simulator to systematically construct simulation models and conduct simulations easily and efficiently. A case study is also presented as an illustrative example.

In this study, the organizational performance is divided into the policy perspective, the customer perspective, and the internal viewpoint rather than the financial perspective. The public institutions selected as examples of this study are public institutes under the Ministry of Environment, which are established to promote environmental industry development and environmental technology development projects, and promote the dissemination and practical use of developed environmental technologies. The public institutions that were the target of the study were concerned about how to define organizational performance and how to improve organizational performance. In addition, the institutions were interested in measuring performance in terms of customers and policies rather than financial performance. As a result of this study, it was found that the public institutions which were the subject of study were not very high in terms of policy, customer, and internal performance. In order to enhance the organization's policy performance, customer performance and internal performance, it is necessary to communicate smoothly among the members of the organization, horizontal organizational structure, encourage participation in the client's policy process, and redesign the business process from the customer's perspective.

In conceptual design of engineering devices, a designer decomposes a required function into sub-functions, so-called functional decomposition, using a kind of functional knowledge representing achievement relations among functions. However, such knowledge about functionality of engineering devices is usually left implicit because each designer possesses it. Even if such knowledge is found in documents, it is often scattered around technical domains and lacks consistency. Aiming at capturing such functional knowledge explicitly and sharing it in design teams, we discuss its systematic description based on functional ontologies which provide common concepts for its consistent and generic description. We propose a new concept named “was of achievement” as a key concept for capturing such functional knowledge. Categorization of typical representations of the knowledge and its organization as is-a hierarchies are also discussed. The generic concepts representing functionality of a device in the functional knowledge are provided by the functional concept ontology, which makes the functional knowledge consistent and applicable to other domains. We also discuss development of a design supporting system using the systematized knowledge, called a functional was server. It helps human designers redesign an existing engineering device by providing a wide range of alternative ways of achievement of the required function in a manner suitable for the viewpoint of each designer and then facilitates innovative design.

Many proteins consist of distinctive domains that can act independently or cooperatively to achieve a unique function. As these domains evolve from a naturally existing repertoire of functional domains, this implies that domain organization is an intrinsic element involved in building the complex structure and function of proteins. Thus, identifying functional domains would appear to be critical to the elucidation of questions related to protein evolution, folding, and the engineering of hybrid proteins for tai- lored applications. However, the simple application of "Lego-like assembly" to the engineering of hybrid proteins is an oversimplification, as many hybrid constructs lack structural stability, usually due to unfavorable domain contacts. Thus, directed evolution, along with computational studies, may help to engineer hybrid proteins with improved physico-chemical properties. Accordingly, this paper introduces several approaches to functional hybrid protein engineering that potentially can be used to create modulators of gene transcription and cell signaling, and novel biosensors to analyze biological functions in vivo.
