The vast majority of the disaster prevention design research in Korea has focused on the macro-level interventions such as examining the existing systems and approaches, instituting revised policies, systematically establishing intervention programs, and evaluating the effectiveness of the interventions. However, little has focused on systematically challenging individuals' awareness using micro-level intervention. The present paper introduces approaches to micro-level intervention by infusing narrative-based simulation, and further suggests the implications on balancing the approaches of both micro-level and macro-level interventions.

Most of the Automatic Fingerprint Identification Systems define the ridge endings and bifurcation points as the minutia for matching. Therefore, the precise extraction of the minutia is critical in raising the efficiency and reliability of the system. The fingerprint images produced through the preprocessing may have the false minutia happened over the process and they can be the factors to decrease the system efficiency This paper suggests the algorithm, which removes the false minutia after extracting the candidate minutia from the thinned binary images of fingerprint images.

Nowadays, more than ever before, many researchers are paying attention to raising the efficiency of a Power converter. In Flyback converter, the resistor of RCD snubber consumes the stored energy in leakage inductor. It play a role in degrading the overall system efficiency Thus, In this paper, a novel energy recovery circuit of Flyback converter is proposed to improve the efficiency. The operational principle of the proposed circuit is explained in detail. And, it is verified through the simulation results.

Because Insulation material is play an important part for normal work of electricity equipment, the study is advanced, but as the voltage of electricity system is raising, we required that new lnsulation material. They have excellent specific against high stress, namely the study of insulation increase and prevention diagnosis of insulation degradation of Epoxy or XLPE and so on. In this thesis. I utilize image processing technique for effective inspection of insulation material degradation.

This paper was constructed to investigate strange attractor in considering speech which is regarded as chaos in that the random signal appears in the deterministic raising system. This paper searches for the delay time from AR model power spectrum for constructing fit attractor for speech signal. As a result of applying Taken's embedding theory to the delay time, an exact correlation dimension solution is obtained. As a result of this consideration of speech, it is found that it has more speaker recognition characteristic parameter, and gains a large speaker discrimination recognition rate.

Venture industry is becoming a driving force of Korean economy in the digital age of the 21 st century. The success of venture business depends on innovative technology, capital investment, and optimal environment providing industrial flexibility. Although venture business is starting to settle down in Korea, many barriers and challenges still remain. The current study analyzes the present status of venture business including fashion business and issues concerning the venture fund raising and provides prospective views to promote and improve venture industry in Korea.

Using an overlapping generations model, this paper examines tax policy effects across generations. The model incorporates housing assets separately from capital assets and includes taxes on labor income, capital income, consumption and housing assets. Tax reforms for each tax rate have different effects on tax burdens across generations and the overall efficiency of the economy, leading to different welfare costs for generations. Specifically, raising housing property taxes results in the smallest welfare loss by future generations, as in the model it does not hurt economic efficiency and the tax burden increases mainly for the elderly, who have accumulated housing assets in preparation for retirement.

The miniturization of a DC-DC converter circuit in connection with the stability is investigated in this paper. As both the capacitance of the smoothing capacitor and the inductance of the reactor are reduced by raising the switching frequency, it is known that the stability of the buck converter declines with the switching frequency but the buck-boost converter has a nearly uniform stability. Furthermore, that in the frequency region above a certain switching frequency the buck-boost converter is suitable for the miniturization of circuit is cleared.
