The remark by Andy Clark that the cleverer our world is, the more difficult we perceive our world and ourselves, is very significant to us living in digital world. As the huge power of Technology are dominating the world, the people are drifting with their body fragmented in diverse kinds of chaos, being are faced with the situation that they should reorganize themselves about personal life and ways of thinking in a new technological environment. This paper approach some characteristics of contemporary society through 'Cyborg' which is the product of limitless human desire and technology. The characteristics in modern times, such as boundary disjoint, hybridity, transformation, fusion, communication with image, digital sensitivity, womanness correspond to those of the Cyborg. This paper also investigates the history of modern Cyborg through animation, one of the remarkable medium in digital age and analyze the cyber punk animation, and by Oshii Mamoru, which provoked the extension of the concept of Cyborg. This paper will give a moment to diagnose what this age is like and to present a reference line of our contemporaries exposed to the surplus images and technology.

The observation system has been developed to investigate the rip currents at Haeundae beach using X-band marine radar. X-band radar system can observe shape, size, and velocity of rip currents, which is difficult to obtain through field observation by conventional device. Algorithms which automatically detect locations, shapes, and magnitudes of rip currents were developed using time averaged X-band radar sea clutter images. X-band sea clutter images are transformed through 3D FFT into 2D wave number spectrum and frequency spectrum. Rip current velocities were estimated using differences in wave-number spectra and wave frequency spectra due to Doppler shift. The algorithm was verified by drift experiments. At Haeundae beach, the radar system exactly located the rip currents and found to be sustained for 1-2 days at fixed locations.

Agn$\grave{e}$s Varda is a French representative female film director. In particular, the method combining subjectivity and objectivity is the most outstanding characteristics. However, it can be said that the method to support this is not only theme of the film but also creation of structure including the exploration for the filmic form different from classical film form. Such an approach accords with No$\ddot{e}$l Burch's refined analysis of filmic form. Therefore, This study aims to aesthetical analysis of the form of producing the structure in modern movies through which is one of the representative work by Agn$\grave{e}$sVarda and won the Golden Lion award in 1985 Venice Film Festival. The theme of the film, the recovery of relationships among people and contacts through the tragic death of drifting life, created a new filmic structure by formative experiment of the film. The formative experiment is the fragmented and repetitive construction with the introductory voice-over, and consists of movement and editing of camera and specific use of flashback and sound through the representation of figures and situations, mixture of narrative and non-narrative style.

This paper deals with optimal mooring system to secure fish cage in a desired location, Through field investigation and paper works, we surveyed disasters by breakdown of cage frame and mooring system due to higher wave attack and selected compliant buoy mooring method for shallow water mooring system against severe coastal external forces. To analyze interaction between external forces and compliant buoy mooring system, theoretical model has developed as quasi-static nonlinear analysis. After verifying the feasibility of the numerical model compared with experiment, static analysis has tried for various mooring systems with different angle of array, number of mooring points, length of horizontal and inclined rope. Optimal mooring method using compliant buoy has selected for fish cage through numerical simulation. This results can apply for preliminary design for cage mooring system.

This study is purposed to discuss attributes and limitations of neo-liberalism and to offer some roles of Christian education corresponding neoliberalism. Neo-liberalism is an econosuperism that entrusts all things to market order, and it regards this market as utopia. It does not remain as just an economical principle, but influences all aspects in human life. Then it shows its religiosity connecting to capitalism. Every human in it is thought of as flexible workforces appropriate to neo-liberalism market. Such being the case neo-liberalsim strenghtens instrumentation in education. Then it distorts freedom and equality, and it weakens traditional values. Because of this, modern people's identity is getting to be lost and their human characters to be floated. This study discusses these things critically, and offers roles of Christian education such as founding a well balanced understanding on the Scripture against this neo-liberalsim market, restoring the essential purpose of education from instrumentation in education, and investigating and applicating a holistic human character on the basis of a Christian anthropology against this new human character of neo-liberalsim.

Simultaneous investigations for drift bottle and dye diffusion experiment were carried out in Suyeong bay. Seawater in Suyeong bay flowed differently in the vicinity of Suyeong river estuary and Nam-cheon Dong respectively. The speed of current did not exceed one knot in this bay. The dye patch moved to Kwangan beach in the dye diffusion experiment. The relationship between apparent diffusivity and diffusion time was appeared as Ka=0.0025t super(1.9). The variance was calculated to be 2.9 power of the diffusion time. And the exponent diffusivity versus the scale of diffusion time was appeared to be 1.3.

The purpose of this study was to classify different profiles of grit (effort vs. interest) and passion mindset (fixed vs. growth) in university students and to understand whether there are differences in psychological characteristics (ie. depression, anxiety and happiness) and career adaptability between the profiles. To this end, we recruited 359 students aged 18 and 25 and applied a Latent Profile Analysis(LPA). The results revealed 4 distinct profiles : Profile1-a burgeoning type, Profile2-an ordinary type, Profile3-a fixed/limited type, Profile4-sprouting/drifting type. The profile1(LP1, 22.2%) had high levels of grit and passion growth mindset. The profile2(LP2, 63.8%) showed average levels in both grit and passion mindset. The profile3(LP3, 8.8%) had a low level of grit and a high level of passion fixed mindset. The profile4(LP4, 5.1%) showed a low level of grit and a high level of passion growth mindset. The four profiles were distinct in psychological characteristics and career adaptability. The burgeoning type(profile1) was most adaptive in comparison to the fixed/limited type(profile 3). These results suggest that grit has more powerful effects on psychological characteristics while passion growth mindset exerts stronger influencers in career adaptability. Putting the results together, our findings imply that both passion growth mindset and grit need to be considered together to enhance the individuals' comprehensive well-being and to increase the level of adaptation for career preparation.

Electronic circuits with semiconductor and IC are very weak against the surge voltage and currents. The surge protective devices for electronic circuit and AC power lines are becoming more widely used. It is possible to give rise to the malfunction of the earth leakage circuit breaker(ELB) due to the operation of surge protective devices, and the interruption of AC power lines on account of the malfunction of the ELB brings about several disadvantages such as low operation efficiency and reliability of electronic and informational systems, economical loss, and etc. The aim of the present work is to investigate the dead operation characteristics of the ELB against the surge voltages. The impulse generator of 10[kV) in an 1.2/ 50[~) voltage waveform was fabricated. The dead operation characteristics of the ELB applied by surge voltages were measured under the conditions of KS C 4613 and the test circuit with a varistor. As a consequence, the peak value of the zero-phase sequence circuit of the ELB is increased as the surge voltage and stray capacitance increase. All of the ELBs used in this work were satisfied with the lightning impulse dead operation test condition defined in KS C 4613. However one specimen only did not bring about dead operation in the condition of the test circuit with a varistor. There is high possibility that a large portion of the ELB installed at the AC power lines with the surge protective devices bring about the dead operation.

A new diagnostics of plasma electron temperature and plasma density is introduced with the observation of the light emission along the tube of external electrode fluorescent lamps. With two different methods operating an external electrode fluorescent lamp of outer diameter 4.0 mm and length 860 mm for the back-light source of 37-inch LCD-TVs, the lighting modes and the plasma properties are investigated. In the center balance operation, the light-emission propagates simultaneously from both sides of the high voltage electrodes to the center of the lamp, while in conventional operation the light-emission propagates from the one end of a high voltage to the other ground electrode. In the operation value of luminance $10,000{\sim}15,000cd/m^2$, the electron plasma thermal energy $(kT_e)$ is about $1.3{\sim}2.7eV$ with the electron density $(n_e)$ is about $(1.6{\sim}3.6){\times}10^{16}m^{-3}$.

The yeongok stream originates at the natural park, Mt. O-dae and flows to the East Sea of korea, normally maintaining I or II grade of water quality and its average water flux is 352,100 ㎥/d. However, the typhoon 'Rusa', which occured on 31 August 2002, changed its watercourse and configuration, and the ecosystem was deeply damaged. Moreover, the hydrological characteristics were once more transformed, and the ecosystem was secondarily damaged during repair-work of destroyed bridges and elevations. After the flood disaster, the species diversity diminished 17% for attached diatom and 44% for aquatic animals. However, the earth and sand, dug from river bed during intensive repair-work throughout the entire stream, made diversity drop to 32% for the diatom and the aquatic animals were wiped out. Especially, fishes were totally destroyed except for some species such as Moroco oxycephalus in the upper stream. The yeongok stream has little contamination source and short water residence time due to the short length and rapid slope, and consequently a temporary deterioration of water quality caused by repair-work may be rapidly recovered, but it needs a long time to restore the damaged ecosystem.
