In the last few years, we have witnessed two alterations in financial accounting and reporting rules concerningpension plans. In the United Kingdom, accounting rule FRS 17, which stipulates the immediate recognition of actuarialgains and losses, will come into force in 2005. Meanwhile, in the United States, FAS 132 was amended in 2004 tostipulate the detailed disclosure of financial expectations and results of pension plan operations and management policies.It is probable that one of these two changes will spread to financial reporting in Japan, as IASB has already adopted themin its new rules. The financial impact that the adoption of these two changes could have in Japan is ambiguous, anddepends in large part on investor behavior. Considering the similarity to current accounting standards and the consistencywith their underlying concepts, it is more likely for Japan to introduce a comprehensive disclosure rule for pensionssimilar to FAS 132 in the U.S than the immediate recognition of actuarial gains and losses similar to FRS17 in the U.K.

The Japanese businesses used to set management goals on attaining a certain rate of increase in sales or increasing the share in the domestic industry, but they have finally begun to place emphasis on return on equity (ROE), which is an indicator of how efficiently shareholders’ equity is being used. Calls for more rigorous corporate governance from domestic and foreign institutional investors are behind this shift. The new trend is expected to accelerate innovations in the Japanese companies’ management system as well as in management control measures. In fact, high-growth companies have been adopting economic value added (EVA) or market value added (MVA) as their management benchmarks in increasing numbers.

How an IT-based society should inform its citizens of potential natural disasters in advance so that they can take preventive measures. This is the main point that this paper is going to consider.The process of urbanization has gone so far as to reach rural and mountainous regions and to expose inhabitants concerned to the threats of natural disasters. Populated areas have expanded. More and more people have come to inhabit areas where no or few people lived formerly. In proportion to that, workings of nature are no longer mere forces of nature, but have become causes of an increasing number of actual threats and disasters. The point is whether local governments or municipal corporations are sufficiently equipped and prepared to provide that kind of information which residents of areas concerned really need and find useful in preventing disasters?The author has looked through disaster prevention information websites, especially of local governments. The examination revealed that some local governments are doing the very best they can to provide necessary information and others make little effort, that the methods they use of providing information are quite various, that this diversity and difference in turn give rise to information gaps between one government and another. These and other facts all point to an important issue: there is still a long way to go before most local governments can provide necessary and sufficient information of natural disasters by means of IT.

This is an attempt to revaluate the world of ideas of Adam Smith in an intellectual-historicalperspective. Instead of judging his system of ideas simply in terms of whether it is “modern” ornot, whether he is a founder of a system of “modern sciences” of society, or from a viewpoint oflogical or theoretical consistencies in his system, the author considers the whole complex of hisideas at those points where two different dimensions of thought meet together. Intellectualexperiments are made by putting his key concepts and main fields of intellectual inquiry at where ahorizontal anthropological plane of each individual field of thought is crossed by a verticalcosmological or theological axis of a hierarchy of values and orders. In this manner, by locatinghis notion of “economy” in the hierarchical order of “divine economy”, “cosmic economy” and“political economy”, as well as in the context of the history of the notion of economy that tracesback to the Aristotelian concept of “oikonomia”, we can get a definite notion of what “politicaleconomy” was about in its early days as a “modern” discipline, and also in what kind of climate ofopinion and against what intellectual background it made itself into what it really became. Thisis a frame of reference in terms of which the author is going to examine the whole world ofSmith’s ideas, so that he can understand what Adam Smith means to the present scene ofphilosophical thinking, and grope his way through an inquiry into what the Society of Mankindought to be in the 21st century.

After the end of World War II, Japanese economy continued to grow phenomenally for a long period of time. This is largely due to a system, called the main bank system, under which business corporations and their main banks are closely and effectively connected. While the system works well, everything goes well. However, when the bubble economy of the 1880s burst, the Japanese economy plunged into a slump which lasted for some ten years – a period usually called “a lost decade.” The system stopped working properly. This malfunction reflects an inadequate monitoring of corporate management and an insufficient risk control of financing.This essay attempts to define the main bank system in a new and broad perspective and consider the relationships between business corporations and their main banks.

With the globalization of development and production, the position of automobile part suppliers is rising. From among auto parts manufacturers that operate and carry out technological innovation overseas, independent of automobile manufacturers at home, a new type of suppliers have emerged – Tier One Automobile Part Suppliers. They can provide key auto parts on a global scale. This is where the Japanese automobile supplier system, in spite of its reputation as a world model, is forced to transform itself.

This is an introductory essay towards establishing what intellectual and cultural heritage Adam Smith (1723-1790), one of the representative figures of the eighteenth-century “Enlightenment”, specifically “Scottish Enlightenment”, left for the twenty-first century. Attempts are made in this essay to analyze and dissect the thought world of Adam Smith in its logical make-up and intellectual-historical setting.The first thing to note is the intellectual interest Smith took throughout his academic career in the seven subjects of “artes liberales” and those fields of study which fell under the three branches of Logic (or a theory of knowledge), Natural Philosophy and Moral Philosophy according to the eighteenth-century British manner of dividing Philosophy, or logikē, physikē and ethikē in the Stoicist division of sciences.Secondly, in his lectures and essays, Smith discussed and criticized several existing branches of learning or systems of ideas, such as natural philosophy, natural theology, natural morality, natural jurisprudence, and so forth. The point to be noted is that while these names referred to those sciences which were actually taught and prevalent in the intellectual climate of the age in question, Smith stressed the “natural” character of every one of these systems. In this sense he was a legitimate successor to Hume in the philosophy of human nature or Moral Philosophy as it was called in the eighteenth-century climate. By “natural”, Smith meant: starting from the basis of human nature and never getting remote from it; according to human nature; in accordance with the principles of human nature; capable of meeting the basic needs of human nature. Bringing ready-made systems of thought back to the foundation of human nature, Smith reduced them to its principles. By using the method of what K. Marx and, following him, a twentieth-century Japanese philosopher K. Miki called “the genealogy of theories”, Smith demonstrated how physical and social theories, systems of thought, moral and ethical rules, social institutions are formed and constituted on the basis, and starting from the foundation, of human nature.It is important to focus upon the vital role which the “imagination” plays in Smith’s system of thought. It is the imagination that, starting from the basis of human nature, brings into a complete form what remains imperfect on the basis of human nature. Insofar, the imagination takes on the task of artificial completion of what nature cannot carry out to an end.These are the questions which the essay tries to examine. This is in order to reconstruct the imagination and remake it; render it original and creative; and as is the subject of the essays to follow, revitalize it so that it can meet the needs of a new intelligence and help it find its way through the chaos of

Industrial clusters in the US, Europe and Asia are equipped with provisions for “quality of life” (QOL), while those in Japan are often artificially located in isolated areas and lack QOL.Knowledge workers appreciate urban convenience, life amenities, open culture, natural environment, leisure activities, and other aspects of QOL, on top of challenging and rewarding jobs; therefore, a region’s QOL, among other factors, can attract and sustain knowledge workers, thereby promoting innovation and strengthening the industrial cluster’s competitiveness. In return, an industrial cluster can create employment, increase a region’s revenues from personal income and other taxes, provide “civic entrepreneurs” who take the leadership of regional development, and improve a region’s QOL.This productive cycle between QOL and industrial clusters can be a key factor in improving a region in a sustainable way. Local governments should not forget to improve the region’s QOL when developing industrial clusters in the age of inter-regional competition in the knowledge economy.

Today the Islam world is confronted with difficult problems of radical political campaigns largely imbued with ideologies of “Islam Fundamentalism”. In several Southeast Asian countries, fierce political movements are often conducted by groups of radical fundamentalists. This is particularly true in the Philippines and Indonesia.However, Malaysia can be regarded as an exception. With the former Prime Minister Mahathir bin Mohamad exercising strong leadership in taking effective measures for public security and economic takeoff, this country has succeeded in subduing extreme fundamentalist movements. Mahathir has been instrumental in securing the peace of the country; during the 22 years in office, by peace-keeping policies, he contributed to establishing the national stability of a country which comprises Malaysians, Chinese, Indians, and other ethnical groups.On October 31, 2003, Mahathir resigned from his post. Abdulah bin Haji Ahmad Badawi succeeded him and took over his office. It is true that Abdulah is now revered and respected by the people. However, his ability as a political leader is still to be seen. Since in Malaysia, internal security and economic development of the country largely depends on the social stability of the Islam groups, it is absolutely necessary to keep security within the country. This is the first thing he has to do. It is up to the new prime minister, and everything depends upon his ability to carry out his own policies and administer the country.

In order to improve control performance in various control fields, it is important to model the controlled object accurately. In this case, the quality of the model is considerably influenced by the structure of the model determined by the engineer. An element description method is a method that can optimize not only parameters but also the structure of the model. Therefore, it is possible to search over a wide range without being restricted by human design. However, this considerably increases the search space, and it is easy to fall into a local solution. In this study, the artificial bee colony algorithm is combined with the element description method to improve its search ability. The artificial bee colony algorithm is known to be effective for high-dimensional and multimodal problems. The performance of the proposed method is validated using a heat sealing system in packaging machinery. The proposed method is evaluated in comparison with the genetic algorithm, which is a conventional method. Experiments confirm that the local solution avoidance performance of the artificial bee colony algorithm is significantly better than that of the genetic algorithm.

This paper proposes relative trajectory designing methods for spacecraft in orbit using the concept of virtual potential field. The potential field is neither a real one, such as gravitational field, nor an arbitrary one without restraint, but the one derived from relative motion equations known as the Hill's equations. This concept allows us to express the relative motion of satellites with a new set of parameters, leading to easy understanding of the relative motion. Potential field principle is attractive because of its simplicity, which allows us to intuitively reach simple and effective control methods for either single or multiple satellites. In the following part, the basics of the virtual potential field concept are presented as well as some results of applying the methods to relative trajectory designing.

Study and long-term prediction of orbital debris environment in low Earth orbits are urgent needs for secure human space development and exploration. This paper introduces some results of Low Earth Orbital Debris Environmental Evolutionary Model (LEODEEM) being researched at Kyushu University with collaboration from JAXA for the purpose of discussing problems of space environment conservation. The model calculates LEO debris evolution (less than 2,000 km altitude of perigee) taking into account collisions, and future launch traffic. It becomes possible to predict a long term LEO environment and investigate future mission hazard evaluation by using this model.

For a reconfigurable antenna system, antenna surface deformations should be measured to achieve a high precision antenna system. In this study, a novel measurement method of antenna surface deformations is proposed. Relations between surface errors and changes of the antenna gains caused by intentional deformations are derived from the Ruze equation. In this method, an antenna surface is deformed additionally using surface adjustment mechanisms and changes of the gains caused by the intentional deformations are measured. An original deformation of the antenna surface is estimated using the relations. Some numerical simulations are carried out to investigate the feasibility of this method. From the results of the simulations, it is shown that the antenna deformations are estimated adequately by using this method.

A correction method of orbit elements for nano-satellites using simple and low cost facilities is required. In this study, the Doppler shift of the beacon signal from a cubesat was observed using an amateur radio. The history of frequency variation was recorded for different TLEs with different epoch time. The frequency difference translated into seconds (FDTS) was deduced as a ratio of the maximum frequency variation in the pass to the 1s-periodic variation. The FDTS has dependency on TLE. For the old TLE, the FDTS was larger than the new one. Because the FDTS is related to satellite's phase variation in the orbit, the TLE's epoch time was corrected using the measurement result. The FDTS with the observation using the corrected TLE was small.

In this paper, a new standard bus system for a series of small scientific satellites in the Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (ISAS/JAXA) is described. Since each mission proposed for the series has a wide variety of requirements, a lot of efforts are needed to enhance flexibility of the standard bus. Some concepts from different viewpoints are proposed. First, standardization layers concerning satellite configuration, instruments, interfaces, and design methods are defined respectively. Methods of product platform engineering, which classify specifications of the bus system into a core platform, alternative variants, and selectable variants, are also investigated in order to realize a semi-custom-made bus. Furthermore, a tradeoff between integration and modularization architecture is fully considered.

JAXA has carried out the hypervelocity impact tests of carbon fiber reinforced plastic (CFRP) plates together with University of Padova. Quasi-isotropic CFRP plates of 2.3, 3.5, and 4.7 mm in thickness were tested. Aluminum sphere of 0.8 to 2.9 mm in diameter was used as projectiles. With a two-stage light gas gun, the projectile was launched with a velocity range of 2 to 5 km/sec in the normal direction to the CFRP plate. Since the perforated hole and the crater on the CFRP plate after the impact are filled with flakes of the carbon fiber, it is difficult to determine the perforation of the projectile. Therefore, whether the projectile perforated the CFRP plate or not was decided by the craters on a copper plate installed behind the CFRP plate. After the impact, peeling along the fiber direction was observed on the surface of the CFRP plate. Moreover, internal delamination was generated near the surface. Finally, a ballistic limit equation of CFRP plates of 2 to 5 mm in thickness was calculated on the basis of the Cour-Palais equation. The ballistic limit equation was in good agreement with the test results.

The Japan Aerospace Exploration Agency (JAXA) is investigating an active space debris removal system that employs highly-efficient electrodynamic tether (EDT) technology. As an electron collector of the EDT for debris de-orbiting, a multiple bare tethers are to be used. In order to simulate the EDT operation, current-voltage (I-V) characteristics of the multiple bare tethers need to be investigated on conditions that a theoretical formula cannot be applied. Therefore, numerical simulations and ground experiments have been conducted to obtain the I-V characteristics. A result of the numerical simulations and the ground experiments showed a double-line bare tethers can collect larger current density than a single-line bare tether.
