  • Information, or the lack of information, is the central concern of many people. And it is now an economic resource and must be paid. An ever increasing gap will grow between information 'have' and 'have not'. The new communications market place is a social phenomenon, and a vital key to examining changing patterns of social and cultural inequality. There are two main arenas of action in this ongoing conflict. Inside the library system itself, a combination of forces is weakening the historic principle of free, socially underwritten access. Outside, great efforts have been exerted in recent years, by private interests, to capture the information stockpiles built up from tax-su n.0, pported outlays on research and development and general governmental activities that produce data. The for-profit a n.0, pplication of the new information technologies threatens the survival of the free access principles. And the commercialization of information is proceeding almost uninterruptedly. It has been extended into areas that historically have been regarded as non-profit-making and endowed with a deep public interest. This study discussed some general issues and what we should do.

  • Ever since gold was found, this element has fascinated human beings. It is stable in air, and is illuminating for several thousands years without changing its colors. Nanoparticles are the basic nanommaterials, and, particularly gold nanoparticles show unique properties which are not shown in bulk states. Scientists are trying to apply these new properties to catalysts, bioscience, optics, etc. Judging from the current research activities, one can envisage that gold nanoparticles can play a major role in opening a new era in diagnoses and treatment of diseases like cancers. However to apply the nanoparticles one must modify the surface of the nanoparticles in order to give the materials certain functionalities. It certainly is worth to review the current research status and challenges in the area of functional gold nanoparticles.

  • The electronic trade(e-Trade) revolution is changing the international trade processes dramatically. It permits new kinds of interactions among exporting and importing firms as well as internally within the firms. Ever since the Internet became a popular communications medium in the 1990s, lawmakers have struggled to develop rules for determining which courts can hear disputes involving parties in different choice of law and jurisdictions. In conclusion, I suggest an ongoing research agenda for further refining and developing a more comprehensive cosmopolitan approach. Certainly, as these cases make clear, reconceptualizing the principles underlying court to-court relations is essential in a world where the idea of a transnational community of courts is fast becoming one of the dominant realities of twenty-first century law.

  • A hybrid system which is combined several complementary new and renewable power sources, such as photovoltaic, fuel-cell, and wind generator, etc., has been presented in various approaches. For instance, a photovoltaic cannot always generate stable output power with ever-changing weather condition, so it might be co-generated with a wind generator, diesel generator, and some other sources. In this paper, a residential PV-FC hybrid system is suggested as a distribution power source, and its operation is optimized by HOMER$^{(R)}$. As a result, it is the most economic that 5[kW] PV, 1[kW] FC, 4 batteries, 2[kW] electrolyzer, 0.5[kg] $H_2$ tank, 3[kW] converter are applied to the hybrid system.

  • Space is comprised by the movements of human beings, and draws a complex locus within it. That form seems to be complex of movement around in all directions of space axis, and be ever-changing process as time goes by. Although Human are able to move uninhibitedly, the movements are restricted to a narrow sphere during locomotion. However, the pattern of these movements delineates a certain frame within the space, and provides not only visual effects but also relevance tomovement itself. Also, critically dividing and organizing this sphere is what is realized into this tangible indoor space. This study recognized importance of human being as a core of making indoor space and brought out experimental approach on relationship human with space, and visually perceptual standpoint. And this presented the recent possibility of action and attitude though sight and walking by arranging space on the basis of modern artists' perception of human body.

  • The mixed-use building is certainly one of the significant alternatives for urban dwelling based on the over-crowded urban condition as well as the ever-changing contemporary life patterns. It is clear that residential and other programs somehow are becoming more separated in most high quality mixed-use buildings in Seoul. Thus making the space between residential and other programs where diverse multi activities can be inserted is extremely important in terms of bridging the different urban programs. This research aims to briefly analyze the mixed-use programs in contemporary cities and case projects to see how they respond to unique characteristics of each projects by creating different mixed zones and spaces.

  • This is an interview with Professor Kwang-Hyung Lee, founding Dean of KAIST Moon Soul Graduates School of Future Strategy and founder of the Department of Bio and Brain Engineering of the same university casting two questions about academics. The first question is what pattern is desirable in the evolution of research topics of an academics. While traditional researchers in science and engineering tend to focus on one subject in ever greater depth over time, Professor Lee's research agenda has spanned several new topics by gradually changing the content of the study: from artificial intelligence to bio and brain research, and to creativity development method, further to future study. The second question is about researchers' social responsibility. He has devoted to contributes to industry fields and the nation through academic activities as well as educating several successful business people, founding a new academic department and graduate school of future studies.

  • This study addresses basic requirements for mathematical programming software, discusses considerations in designing these software, implementation issues facing in these types of applications development, and shows some examples of codes being developed in the course. This type of projects requires long and ever-changing evolutionary phases. The experience is therefore, valuaable in suggesting some useful hints which may be salvaged for similar projects as well as providing reusable codes. In particular, scanning and parsing the free-format inputs, symbol table management, mixed-language programming, and data structures dealing with large sparse matrices are indispensable to many management science software development. Extensions to be made are also discussed.

  • Urinary tract infection (UTI), the most common bacterial disease in childhood, is frequently associated with urinary tract anomalies (15-50%) and can induce renal scarring, which is a cause of hypertension and chronic kidney disease. Despite the high risk of renal scarring in infancy, the diagnosis may be delayed due to its nonspecific presenting symptoms; moreover, over-diagnosis is frequent due to the contamination of urine samples. The delay in diagnosis and treatment may induce sepsis or renal scar, while over-diagnosis is responsible for unnecessary antibiotic treatment and costly urinary imaging studies. UTI guidelines have been ever-changing for the past three decades, but some controversial issues remain. This article is a revision of the previous KSPN (Korean Society of Pediatric Nephrology) guideline and addresses the recent controversies concerning childhood UTI.

  • Because of the liberalization of Korean financial markets, domestic commercial banks are exposed to various risks including interest rate risk and foreign exchange risk. Therefore, asset liability management, developed to manage the risks and profitability of financial institutes systematically, is considered prerequisite for the success in more and more competitive financial environments. However, developing a high value-added software is not easy work because of the lack of domain knowlege and ever-changing financial environments. In this paper, we present a computer model for asset liability management systems. A prototype system is implemented by using Visual Basic 3.0 (professional version) and Access database, based on the 3-tiered client/server model.
