  • Novel class AB CMOS second-generation current conveyors (CCII) using 0.6.mu.m n-well CMOS process for high-frequency current-mode signal processing were developed. The CCII for low power operation consists of a class AB push-pull stage for the current input, a complementary source follower for the voltage input, and a cascode current mirror for the current output. In this architecture, the two input stages are coupled by current mirrors to reduce the current input impedance. Measurements of the fabricated CCII show that the current input impedance is 875.ohm. and the bandwidth of flat gain when used as a voltage amplifier extends beyond 4MHz. The power dissipation is 1.25mW and the active chip area is 0.2*0.15[mm$\^$2/].

  • With the booming complementary medicine as a social trend of well-being, treatment by the sound waves of six kinds of syllables is believed to restore that healthy balance to the body. Sound therapy refers to a range of therapies in which sound is used to treat physical and mental conditions. Healing is done by transmitting beneficial sound to the affected area related to five viscera and six bowels. The healing sound may be produced by a voice. sound wave vibrations are to treat physical and mental conditions. In general, this therapy is based on the theory that all of life vibrates, including people's bodies. When a person's healthy resonant frequency is out of balance, physical and emotional health is affected. When a person's healthy resonant frequency is out of balance, physical and emotional health is affected. This paper focuses on the sound therapy by six syllables of 'hyu', 'huo', 'ho', 'sa', 'chi' and 'hui'.

  • We generated single-crystal organic nanowire arrays using a direct printing method (liquidbridge- mediated nanotransfer molding) that enables the simultaneous synthesis, alignment and patterning of nanowires from molecular ink solutions. Using this method, single-crystal organic nanowires can easily be synthesized by self-assembly and crystallization of organic molecules within the nanoscale channels of molds, and these nanowires can then be directly transferred to specific positions on substrates to generate nanowire arrays by a direct printing process. The position of the nanowires on complex structures is easy to adjust, because the mold is movable on the substrates before the polar liquid layer, which acts as an adhesive lubricant, is dried. Repeated application of the direct printing process can be used to produce organic nanowire-integrated electronics with twoor three-dimensional complex structures on large-area flexible substrates. This efficient manufacturing method is used to fabricate all-organic nanowire field-effect transistors that are integrated into device arrays and inverters on flexible plastic substrates.

  • The purpose of this study is to estimate the benefits associated with the opportunities of multiple destination trips using a mixed logit model. The opportunities that affect the destination choice can be one of the external environments of recreational sites. The data for this study were taken from a survey conducted to the multiple destination trip participants at Seorak National Park in Korea. The results of the research show the specific values of complementary opportunities in the study area.

  • Understanding what lies beneath the relationship between ISP and its implementation is an significant area of inquiry in the ISP research. Through an empirical analysis and complementary case examples the current study examines this relationship at six different university sites which undergone both of these processes years from 1995 to 2001. The face-to-face, in-depth interviews were conducted to those participated in both of these processes. A questionnaire survey was also conducted to same participants to elevate the quality of the validity and reliability of the measures. Due to the limitation of the access to the data, it was not possible to compare how similar the final implementation outcomes are from what was originally planned in ISP to some sites. However the study finds that such organizational factors as management support, communication, and organizational culture at the ISP play an important role in the implementation process. This paper proposes that these organizational factors although little they seem to directly affect each individual elements in the implementation process, its latent impact is critical as a whole.

  • It is necessary to draw up many plans to solve problems in the management of groundwater resources in Jeju Island while systematically develop and utilize water resources at an optimal level. It also seems to an evitable option to establish Groundwater Management Areas in Jeju Island. The excess use of groundwater could be discouraged by imposing charges on those licenses. Such policy as allowance trading system do not appear to be because of transaction costs, but could be applied if only were accompanied by complementary method. The methods of using and conserving the limited resources of groundwater should be founded through socially agreeable and appropriate ways. The policy complemented allowance trading system by Pigouian tax could be effective to regulate licenses. This is cutting the numbers of licenses at a constant rate, imposing charges on those who want to continue using licenses, and reimbursing in cash to those who return the licenses.

  • Korea and Japan have maintained an intimate relationship of economic exchange. However, even though both countries have made sound advances in the ASIAN market, they have not established mutually remarkable cooperative relations and advances in the ASIAN market. If korean companies with abundant experience and management ability provide able managers and skilled labor and if Japanese companies provide construction technology, capital and information, they could enjoy enomorous mutual benefits by advancing in the area of plant construction in foreign countries. Therefore, if they cooperate with each other by establishing complementary cooperation, both countries can gain an advantage in international competitiveness with western advanced countries.

  • The use of complementary and alternative medicine (CAM) is currently widespread and appears to be growing. As an increasing proportion of the population turns to CAM therapies, whether singly or in combination with allopathic medicine, the need for quality research in this area is reinforced. Much of this research consists of clinical studies aim ed primarily at clinicians, yet challenges arising from poor methodological quality will occur w hen interpreting study findings and their implications. For clinicians to be effective consumers of the scientific literature, familiarization with the principles of evidence based medicine (EBM) is essential. The goal of this review is to introduce clinicians to the concept of critical appraisal of clinical studies and foster critical thinking when reading research articles in order to best evaluate and incorporate study findings into their daily practice.

  • The problem of discovering association rules is an emerging research area, whose goal is to extract significant patterns or interesting rules from large databases and several algorithms for mining association rules have been applied to item-oriented sales transaction databases. Data warehouses and OLAP engines are expected to be widely available. OLAP and data mining are complementary; both are important parts of exploiting data. Our study shows that data cube is an efficient structure for mining association rules. OLAP databases are expected to be a major platform for data mining in the future. In this paper, we present an efficient and effective algorithm for mining association rules using data cube. The algorithm can be applicable to enhance the power of competitiveness of business organizations by providing rapid decision support and efficient database marketing through customer segmentation.
