This study is to analyse the reimbursement prices of drugs in Japan. Japan has the world's second-largest pharmaceutical market, and the world's largest price-controlled pharmaceutical market. The reimbursement prices of new drugs in Japan are determined by confidential negotiations between the manufacturer and the Japanese Ministry of Health, Labor, and Welfare. Pharmaceuticals account for a larger share of total healthcare expenditures in Japan than in most other major pharmaceutical markets such as France, Germany, United Kingdom and United States. Prescription drugs' share of total healthcare spending has slightly increased in recent years, from 20.2% in 2000 to 21.5% in 2004, the most recent year for which data are currently available. This trend is attributable to the effect of the Japanese rapidly aging population that stimulates demand for healthcare services. There are several method of price setting for drugs as below. First, on the initial pricing of branded drugs, is the similar-efficacy pricing method and cost calculation method. Second is postmarketing price changes which are biennial price revisions under the rule of National Health Insurance. Third is the rule of the generics price. Recently, the generics market is expanded because there are increasing numbers of hospitals by DPCs(Diagnosis-procedure Combinations).

In recent environment of dynamic management, there is growing recognition that information and knowledge management systems are essential for efficient/effective decision making by CEO. To cope with this situation, we suggest the Data-Miming scheme as a key component of integrated information and knowledge management system. The proposed system measures business performance by considering both VA(Value-Added), which represents stakeholder’s point of view and EVA (Economic Value-Added), which represents shareholder’s point of view. To mine the new information & Knowledge discovery, we applied the improved genetic algorithms that consider predictability, understandability (lucidity) and reasonability factors simultaneously, we use a linear combination model for GAs learning structure. Although this model’s predictability will be more decreased than non-linear model, this model can increase the knowledge’s understandability that is meaning of induced values. Moreover, we introduce a random variable scheme based on normal distribution for initial chromosomes in GAs, so we can expect to increase the knowledge’s reasonability that is degree of expert’s acceptability. the random variable scheme based on normal distribution uses statistical correlation/determination coefficient that is calculated with training data. To demonstrate the performance of the system, we conducted a case study using financial data of Korean automobile industry over 16 years from 1981 to 1996, which is taken from database of KISFAS (Korea Investors Services Financial Analysis System).

Medical technology being developed, the increase of the aged population brings about many changes in financial standard, consciousness and lifestyle. And the increase of a nuclear family and a professional woman makes their family not to be able to support them anymore. Because aged people also don't want to rely on their family, aged people households are growing gradually. These causes make a house and a living environment of aged people to new social problems and these became elements to determine the living quality. In case of advanced nations a house considered of the physical character of aged people has been planned and they can live with various services in their houses and community that they are living without moving: But a hou! se for aged people is initial stage in Korea. And most facilities are poor and just for protection and accommodation. Although concerning a house for the aged according to revised the aged welfare law, companies are waiting to build because of problems of cognition and regulation. Therefore the plan considered of the character of the aged is being needed for the independent and comfortable living of the aged.

Motion control schemes are generally classified into three categories (point stabilization, trajectory tracking, and path following). This paper deals with the problem which is associated with the initial deployment of a group of Unmanned Surface Vehicle (USVs) and corresponding point stabilization. To keep the formation of a group of USVs, it is necessary to set the relationship between each vehicle. A forcing functions such as potential fields are designed to keep the formation and a graph Laplacian is used to represent the connectivity between vehicle. In case of fixed topology of the graph representing the communication between the vehicles, the graph Laplacian is assumed constant. However the graph topologies are allowed to change as the vehicles move, and the system dynamics become discontinuous in nature because the graph Laplacian changes as time passes. To check the stability in the stage of deployment, the system is modeled with Kronecker algebra notation. Filippov's calculus of differential equations with discontinuous right hand sides is then used to formally characterize the behavior of USVs. The stability of the system is analyzed with Lyapunov's stability theory and LaSalle's invariance principle, and the validity is shown by checking the variation of state norm.

This paper presents a weighted fuzzy backward reasoning algorithm for rule-based systems based on weighted fuzzy Petri nets. The fuzzy production rules in the knowledge base of a rule-based system are modeled by weighted fuzzy Petri nets, where the truth values of the propositions appearing in the fuzzy production rules and the certainty factors of the rules are represented by fuzzy numbers. Furthermore, the weights of the propositions appearing in the rules are also represented by fuzzy numbers. The proposed weighted fuzzy backward reasoning generates the backward reasoning path from the goal node to the initial nodes and then evaluates the certainty factor of the goal node. The algorithm we proposed can allow the rule-based systems to perform weighted fuzzy backward reasoning in more flexible and human-like manner.

Purpose: This study was conducted to provide fundamental information for a system establishment of advanced practice nursing for gynecological cancer patients (APN-GCP). Method: Data was collected by focus group and individual interviews and analyzed in the framework of the Grounded theory method mapped by Strauss and Corbin (1990). There were 13 subjects in this study (nurses, doctors, patient and her family). Result: We identified 87 concepts, 22 sub-categories, and 10 categories. Categories for role expectation were arrangement of diagnosis and treatment process, giving information of treatment course, support of treatment process, patients' right toward making a decision of treatment, counseling and teaching after discharge from hospital, medical insurance and financial problems, counseling about sexual problems and use of family and community resources. All subjects perceived the necessity of an APN-GCP. An APN-GCP requires over 2$\sim$7 years clinical experience and a master's degree. Services would be performed from initial registration to termination of treatment or death, and accomplished on an outpatient clinic basis. Conclusion: The nursing delivery system and curriculum should be developed for a women's health nurse practitioner including APN-GCP. As a further step, cost-effectiveness and projected estimation of manpower of APN-GCP should be studied in the future.

Because the local governments has closet contact for public services compared to central government, their role is important in the age when welfare issue is more important than before. So Local Public Finance being important than ever, but regrettably local financial issues related to the mostly negative. In particular, many local government face problem of local fiscal independence, as a result, they have hard time to secure financial resources. Reliant local finance by central government can be alternative, however, it causes negative effect for autonomous management of local finance and fiscal soundness. In this study, public data by public institutions is suggested as solution to secure financial resources. Although, utilization of public data is initial level, this paper deal with exploratory discussion for public data as self-reliant local finance with validity and suggestions.

Technology-driven development of a new system makes it difficult for users and stakeholders to identify or intervene in the development process, resulting in systems with unnecessary functions and poor quality services. Applying the software architecture design process to the initial design of the navigation system platform of autonomous ships enables the development of a system that reflects the required functions and service quality of the stakeholders. The design, which includes all of the subsystems that make up an autonomous ship platform, is close to an enterprise architecture. Thus, we strived to design a navigation system platform suitable for the design range of the software architecture. This study analyzed the definition of functional requirements, and quality attributes by applying the software architecture design procedure. This study was conducted to identify the characteristics of the navigation system and platform needs, and the stakeholders were identified. To derive the functional requirements and constraints of the platform, a quality attributes workshop was held engaging stakeholders, and the results of the analysis of functional requirements and quality attributes were listed. Based on the results of this study, the architect can establish the evidence and technical solutions that are integral for the architecture development, and will facilitate the creation of quality attribute scenarios.
