Mobility, one of the key concepts to evaluate the effect of a transportation policy such as TDM and mobility management as well as to analyze the problems such as social exclusion, must be measured by how much of an intention to make a trip can be realized, not merely by how many trips are available. The advent of new communication tools such as the Internet and mobile phones has allowed one to accomplish certain tasks that previously required a trip. This new situation has brought up a discussion over the necessity to incorporate telecommunications as an aspect of mobility. Aware of such discussions, we analyzed the relationship between the number of trips and telecommunications based on the data we collected on trips, telecommunications, and activities, and found some significant correlations. Our study which used an ordered regression model found several significant relationships between the individual attributes and the number of trips/telecommunications. We formulated a model which assumes the latent factors among the trips and telecommunications. In addition, we found that the latent factors construable as intentions to trips and telecommunications could be measured better by e-mails than by trips. These results indicate that measuring mobility requires the inclusion of information about telecommunications. © 2009 Elsevier Ltd. All rights reserved.

This study proposes a model of placing a liaison which forms relations to all members in the same level of a pyramid organization structure such that the communication of information between every member in the organization becomes the most efficient. This model considers that lengths between the liaison and the other members are more than those between members except the liaison in the organization. When an added node of liaison gets adjacent to all nodes with the same depth TV in a complete binary tree of height H where the lengths of edges between the liaison and the other members are L(l < L < 2) while those of edges between members except the liaison are 1, we obtained an optimal depth N< = H which maximizes the total shortening distance which is the sum of shortening lengths of shortest paths between every pair of all nodes in a complete binary tree. © 2014 IEEE.

Efficient project management is demanded to solve project management problems. Project success or failure depends on the skill of the project manager. A good project manager must have good knowledge on project management and growth. If knowledge is considered a judgment for effective action, the manager's action and experience must first be registered. This paper defines knowledge as a group of low-level information and data. Such knowledge must be registered easily. Since it is difficult to find the appropriate timing for registering knowledge, this paper shows how to maximize such timing and registration for the knowledge. Knowledge is information and data for execution performance that is improvement for project management. We constructed a prototype using WEB technology to collect large amounts of knowledge for projectmanagement, but such knowledge must be registered manually and it is difficult to find the time that information should be registered on. This paper discusses how to find the best timing for registering knowledge. We tried to take into the change in progress of the project in order to get the knowledge. Earned Value Management (EVM), which is one way to manage project progress, is examined to find change in project progress, since the time that progress changes appears to be the best timing for registration. It was found that knowledge may be able to be registered automatically. It will be necessary to achieve the function to register the knowledge at the just timing in the future.

This paper proposes a model of placing liaisons in multi-levels of a pyramid organization structure such that the communication of information between every member in the organization becomes the most efficient. When L nodes of liaisons which get adjacent to all nodes at each depth of L depths are placed in a complete binary tree of height H, an optimal set of depths {N1, N2,⋯, NL}(H ≥ N1 > N2 >⋯ > NL ≥ 2) is obtained by minimizing the total distance which is the sum of lengths of shortest paths between every pair of all nodes in the complete binary tree. It is shown that {N1, N2,⋯, NL}L = {H, H-1,⋯, H-L+1}. © 2013 IEEE.

The present study discusses the retailer's optimal replenishment policy for products with a seasonal demand pattern. The demand of seasonal merchandise such as clothes, sporting goods, children's toys and electrical home appearances tends to decrease with time up to the end of the selling season. In this study, we focus on "Special Display Goods", which are heaped up in end displays or special areas at retail store. They are sold at a fast velocity when their quantity displayed is large, but are sold at a low velocity if the quantity becomes small. We develop the model with a finite time horizon (period of a season) to determine the optimal replenishment policy, which maximizes the retailer's total profit. Numerical examples are presented to illustrate the theoretical underpinnings of the proposed model.

To solve several types of project management problems, efficient project management is being demanded. Success or failure of the project hangs to the skill of project manager. If the knowledge is considered to be a kind of judgment for the effective action, first of all the registration of manager's action and experience is needed. Group of low-level information and data is called knowledge in this paper. It is necessary to register the knowledge easily. But it is difficult to find the timing to register the knowledge. It is difficult to find the time that information should be registered on. This paper describes the method of finding the best timing to have to register the knowledge. I tried to take into the change in progress of the project in order to get the knowledge in addition to the EVM method. EVM (Earned Value Management) is one of the methods for scientific managing the progress of the project. On the other hand, the time that progress changes seem the best timing of registration. As the result, it has been understood that there is a possibility that the knowledge can be registered automatically. © Springer-Verlag London 2013.

This paper proposes a model of adding relation to a linking pin organization structure where every pair of siblings in a complete binary tree of height H is adjacent such that the communication of information in the organization becomes the most efficient. For a model of adding an edge between a node with a depth M and its descendant with a depth N, we formulated the total shortening distance which is the sum of shortening lengths of shortest paths between every pair of all nodes and obtained an optimal depth N â̂ - which maximizes the total shortening distance for each value of M. © 2013 Springer Science+Business Media Dordrecht.

Studies in Japan and the United States investigate preferences for patient-physician decision-making style among young adults in the context of a primary care clinic visit for an upper respiratory infection. A treatment scenario described 1 of 3 decision-making styles: a young adult and doctor using a passive (physician decides), shared (patient and physician decide together), or autonomous (patient decides from a set of medically appropriate alternatives) decision-making style. Unexpectedly, Japanese respondents evaluated the autonomous interaction most positively. US respondents evaluated the shared decision-making scenario most positively. Overall, despite large cultural differences, both country samples favored higher participation in decision making. These results suggest that passive patient approaches are falling out of favor as patient-centered care expectations diffuse globally, even in traditionally hierarchic societies with high levels of respect for authority. The implications of these findings along with managerial implications and suggestions for future research are presented. © 2012 Asia-Pacific Academic Consortium for Public Health.

Methods of evaluating various subjective factors are needed in both the medical and industrial fields. For example reducing costs and shortening the duration of projects are significant issues in system development projects[1][2]. Thus prioritization is essential to meet budgets and schedules. Managers need to evaluate and begin tasks which can be completed with the current resources. In order to efficiently schedule entire projects, it is vital for all project staff to carefully consider their entire schedules in order to improve overall productivity. Evaluation is necessary in order to prioritize resources. To evaluate the appropriate priority of tasks, their urgency and difficulty are the most pertinent factors. However both urgency and difficulty are subjective, thus they are difficult to evaluate [3]. Recently, the medical fields both have been focused on increasing safety and patient-centeredness. Thus this paper introduces the Particle Accumulation Theory which is a tool to assist in the evaluation of resources. The purpose of the Particle Accumulation Theory is to simulate the mechanism of human pattern recognition, as in the synaptic responses of a neural network, through using simultaneous data streams. This paper introduces the possibility of simulating of human pattern recognition by using the Particle Accumulation Theory. The main purpose of this paper is to explain the Particle Accumulation Theory method of evaluating various subjective factors. © 2015 IEEE.

This study proposes a model of placing a liaison which forms relations with long communication lengths to two members in the same level of a pyramid organization structure such that the communication of information between every member in the organization becomes the most efficient. When an added node of liaison gets adjacent to two nodes with the same depth N in a complete K-ary tree of height H where the lengths of edges between the liaison and the other members are L (1 < L < 2) while those of edges between members except the liaison are 1, the total shortening distance which is the sum of shortening lengths of shortest paths between every pair of all nodes in the complete K-ary tree is formulated to obtain an optimal pair of two members to which the liaison forms relations. © 2015 IEEE.
