The modem world has brought a wave of changes, not the least of which is globalization or what is often referred to as the "borderless society." In recent times, changes in the global business environment, such as trade deregulation and advances in technology, are challenging us to find new ways of thinking about and coping with these new forces. The field of global logistics has encountered a host of paradigm shifts as well. Therefore, it is critical that managers involved in international logistics take into account perceptional swift or at least understand the value of fully utilizing information. The appropriate management of human resources is a key factor in dealing with not only new information technology, but also shifts in the business environment. In particular, it will be important for Korea's logistics managers at international logistics companies to continually work to develop themselves, as they must carry out a critical role in global supply chain management. If they fail to take heed of the demand's of the new environment, the competitiveness of Korean enterprises in international logistics will suffer severely.

Deconstruction Architecture takes various approaching ways in the plural situation of modem times while it has a common thinking way in the whole area of society, art field, etc. This plural phenomenon is expressed by collage used as a painting technique. We examine the relations of collage and Deconstruction Architecture to see what kind of space formation factor collage is applied in the Deconstruction Architecture, which can be applied to the architecture composing vocabulary, and classify the aspects that collage technique is expressed with space formation factor of Deconstruction Architecture by category. We can see that superimpositon, interpenetration, juxtaposition, scaling, open structure, undecidability, assemblage, etc. are expressed as various factors in the space of Deconstruction.

Song is a significant message with organic combination of relics and melody. As such, songs could be an important way to deliver messages in the relics and melodies. Among the several kinds of songs ‘popular song’ is the most common and has the strongest effect on the public. On this purpose, total 700 songs published from 1995 to 2001 popular songs have been researched after extracting 100 songs chronologically in regards of broadcasting times, popularity rankings and records of yearly awards during its production year. These selected popular songs have been collected and studied before sampling the expression of the costume included in the relics. Clothes, hair styling, make-up, shoes & purses, accessaries and body figure, etc. are covered In this study. As the recent symbolism embedded in the relics of popular songs is closely related with our generation background, public preference & dislike and the change of modem costume, it shows the symbolism of costumes evidently again.

In this paper, we present bit error rate(BER) performance of an adaptive decision feedback equalizer(DFE) using experimental data. The experiment was performed at the shore of Geoje in November 2007. The BER of the adaptive DFE whose tap weight is updated by RLS is described with change of feedforward filter length, feedback filter length, training sequence length, and delay, which shows that the uncoded average BER is $4{\times}10^2\;and\;1.5{\times}10^{-2}$ with transmission range of 9.7km and 4km, respectively. The BER of the adaptive DFE can be lower than 10-3 by a forward error correction code and therefore the adaptive DFE may be a good candidate for a high speed AUV communications since the volume and weight of the underwater acoustic modem should be small because of the restricted space and power in the battery-operated AUV.

Microwave Otters are essential device in modem wireless systems. A compact dimension BPF(Band-pass Filter) for IEEE 802.11a WLAN service is realized using LTCC multi-layer process. To extrude 2-stage band-pass equivalent circuit, band-pass and J-inverter transform applied to Chebyshev low-pass prototype filter. Because parallel L-C resonator is complicate and hard to control the inductor characteristics in high frequency, the shorted $\lambda/4$ stripline is selected for the resonator structure. The passive element is located in the different layers connected by conventional via structure and isolated by inner GND. The dimension of fabricated stacked band-pass filter which is composed of six layers, is $2.51\times2.27\times1.02\;mm^3$. The measured filter characteristics show the insertion loss of -2.25 dB, half-power bandwidth of 220 MHz, attenuation at 5.7 GHz of -32.25 dB and group delay of 0.9 ns at 5.25 GHz.

This paper describes a 3 to 5 GHz frequency synthesizer for MB-OFDM (Multi-Band OFDM) UWB (Ultra- Wideband) application using 0.13 ${\mu}m$ CMOS process. The frequency synthesizer operates in the band group 1 whose center frequencies are 3432 MHz 3960 MHz, and 4488 MHz. To cover the overall frequencies of group 1, an efficient frequency planning minimizing a number of blocks and the power consumption are proposed. And, a high-frequency VCO and LO Mixer architecture are also presented in this paper. A new mixed coarse tuning scheme that utilizes the MIM capacitance, the varactor arrays, and the DAC is proposed to expand the VCO tuning range. The frequency synthesizer can also provide the clock for the ADC in baseband modem. So, the PLL for the ADC in the baseband modem can be removed with this frequency synthesizer. The single PLL and two SSB-mixers consume 60 mW from a 1.2 sV supply. The VCO tuning range is 1.2 GHz. The simulated phase noise of the VCO is -112 dBc/Hz at 1 MHz offset. The die area is 2 ${\times}$ 2mm$^2$.

The result of this paper runs as follows: 1. The theory of preclinic phase (=mibyung) was scientifically completed as one basic philosophy in "NAEKYUNG(內經)" and on influenced in the coming generations. Two principles for mibyung is to grow good energy and to avoid etiological cause. 2. So far oriental medicine has responded to already diseases, while to recognize the importance of mibyung is to convert it into preventive medicine which study and improve health. In spite of the opinion that no disease is health and no health is disease, the contrite of medical approch by the relative importance is necessary by understanding the steps of mibyung between health and disease with subdividing the steps of the occurance therefore, the scope of oriental medicine may be recognized from every disease to mibyung, that is, health. 3. Diagnosing and treating in the step of mibyung has more important meaning than suffering step because the checkup of mibyung means early examination and treatment. Mibyung can make an opportunity that improve scientific contradiction and defect of oriental medicine. However, scince the theory and practice lack the arrangement and study, much exertion and discussion is necessary.4. The diagnosis and cure in mibyung doesn't have many methods for treating, its index and standard isn't nified, and related theory is of small quantity. But the most prominent means of solution. with combination with other sciences and through the convertion into modem clinical examination, is to accomplish moderization, objectivity and indexation, etc. 5. The representive mibyungs are a hereditary disease, immune lack, mutation, early tumor, incubation of hepatitis and each infectious diseases, stress, etc. Since every science is the product of the times, it has the historical limits. As the times develop, the desire for good health is growing. Therefore we should consider above request in this times.

73 percent of online games in Korea hold perspectives of medieval times in them. So far in history, about a millennium in medieval times is said to be a period of darkness and savagery, but it is newly revived in the digital virtual world. Such phenomenon is paradoxical and meaningful to often bring out 'medieval times' as a theme for online games, which are revealed by up-to-date technologies in present days. This research examines the background of views of medieval times appeared in online games and how they are realized. Medieval fantasy games have appeared because people dream about escaping from pre-modem times and have fantasy about medieval times. Moreover, perspectives of medieval times have enormously influenced background epics, quest stories, creation of characters in a game scenario. The dual structure having coexistence of nature and super naturalness acts an important role to set up the epic for medieval fantasy games. And medieval romance literature, which has a three-step quest narrative of 'targeting - adventure and fight - achievement' is reflected in a quest story of medieval fantasy games. The strict pyramid system represented by feudalism forms a meaningful metaphor for designing characters, and players organize communities for online games through horizontal collective consciousness in such vertical system of history at the same time.
