Introduction

 This book consists of seven chapters as follows:
Chapter 1, by Munenori Kitahara, refers to a legal justice through a fusion of law and information technology. The author will deal with a relationship between law and information technology. Legal states would require the residents and the organizations of lawful behaviors and business activities. The customers could lawfully purchase goods and services via the Internet by using their own terminal devices. The business entities could carry on the enterprises on the information systems complying with regulations. Because the computers and the information systems would guarantee the legality and the compliance. In other words, the information technologies could lead the customers and the entities to lawful behaviors as well as complying enterprises. This research will aim at realizing the content of law through a fusion of law and information technology. The fusion is composed of information society law, privacy law, data protection law and information security law as well as information technologies, such as privacy enhancing technology, internet communication technology and encryption technology. In the fusion of the information environment, the technologies will guarantee legality of one's behaviors and compliance of organizations with applied laws.
 Chapter 2, by Takeshi Ogawa, will deal with the literature on Ricardian models. This study reviews existing literature on Ricardian models with joint production, primarily for the schematizable three-good case, and presents new ideas on the definition of secondary products and efficient specialization patterns. The term “secondary product,” often encountered in a world of joint production, is difficult to define definitively; this study reconsiders the definition. Further, the three-country, three-good model contains a known possibility of multiple efficient specialization patterns (each country specializing in a different production process). We demonstrate that introducing joint production leads to the possibility of price curves intersecting at the boundary where the specialized goods change.
 Chapter 3, by Kouhei Iyori will examine on a cellular automata model of an oligopolistic market with network externality. The author describes a cellular automata model of an oligopolistic market with network externality. When consumers buy a product, they sometimes take their neighbors' choices into consideration. We introduce the effect of consumer decisions into a market model and perform computer simulations under various conditions. The results of simulations show that (1) the final state of the market can be classified into four cases; (2) as neighborhood size increases, the rate of the case where products share the market decreases; and (3) the market requires long periods to reach the final state for a certain neighborhood range.
 Chapter 4, by Takashi Yano and Hiroyuki Kosaka will analyze the effects of tariff reduction between Japan and the United States on the Asia-Pacific region. The purpose of this chapter is to develop a multi-country multi-sectoral model and to demonstrate its application. Regarding the model, the following features are included: 1) the model is constructed by using multi-period international input-output tables in constant prices and international dollars, 2) most parameters of the model are econometrically estimated, 3) the monopoly model is incorporated, 4) input coefficient varies over time, 5) sectoral price and output are simultaneously determined. As an application, the effects of tariff reduction between Japan and the United States on the Asia-Pacific region are quantified. Based on the results, the United States would have positive impact while Japan's findings would be negative with respect to output. The main cause of Japan's output decline is the shift in demand from domestic products to U.S. products due to improved U.S. price competitiveness in Japan's market.
 Chapter 5 by Michinori Sakaguchi and Masanori Kodama will deal with the inventory models. Stochastic inventory models with salvaged opportunities at the beginning of each period are constructed in order to research the inventory system with style goods. These inventory models are equipping the notion of demand changes with time in the period. The demand distribution is assumed to be a general continuous distribution. It is attempted to get the way to reduce the expectation of the total inventory cost analytically by differentiating the object function.
We state precisely the optimal policies in the inventory model of single period. There are two threshold levels which are founded by solving equations, and using them the object function would take the minimal value at there.
 Chapter 6 by Setsuko Sakai and Tetsuyuki Takahama will propose a new current-to-pbest strategy. A key issue in interactive evolutionary computation is to reduce fatigue of a user when the use revaluates candidate solutions. In a pairwise comparison, the user compares two solutions at a time and judges which is superior or inferior. It is thought that the fatigue can be reduced by using the pairwise comparison, compared with usual comparisons where all solutions are compared at a time. In this study, interactive differential evolution (interactive DE, IDE) using the pairwise comparison is improved to realize efficient search by introducing adaptive parameter control into IDE. One of the most successful studies on the adaptive parameter control in DE is JADE. In JADE, two parameter values for DE are generated according to a probability density function which is learned by the parameter values in success cases. There are two problems to introduce the parameter control of JADE into IDE. Sufficient number of function evaluations required for the parameter control is not provided in order to avoid the fatigue. The mutation strategy “current-to-pbest” cannot be adopted in IDE because only the order relation between a parent and its child is provided in pairwise comparison. In this chapter, we study an effective parameter control when the number of function evaluations is limited and “current-to-pbest” strategy is not adopted.
 Chapter 7 by Ryoko Wada and Yoshio Agaoka will deal with harmonic polynomials of more degree. There have been many studies for classical harmonic polynomials on Cp. On the other hand, Kostant-Rallis introduced more general denition of harmonic polynomials from the Lie algebraic viewpoint. According to this viewpoint, these classical harmonic polynomials on Cp can be canonically identied with the harmonic polynomials corresponding to the Lie algebra 𝔰𝔬(p, 1), which is the case of real rank 1. In our previous paper we consider some properties of generalized harmonic polynomials in the case 𝔰𝔬(p, 2), which is the case of real rank 2 and show some results about harmonic polynomials of degree ≤ 4. In this paper we consider for these harmonic polynomials of more general degree.
