        특허결정은 특허출원인에게 유리한 결정이라 는 전제에서 특허법에서 별도로 불복의 길을 마련 하고 있지 않다. 그런데 특허법 제224조의2는 특허 여부결정(특허결정 및 특허불복결정)에 대하여는 다른 법에 따른 불복이 허용되지 않는다고 규정하 고 있다. 따라서, 특허출원인에게 불리한 점이 있는 특허결정에 대하여는 일응 행정소송이 허용되지 않는다 할 것이다. 그러나, 특허출원인의 보호 나아 가 발명자의 권리보호를 통한 경제발전이라는 특 허법의 목적을 위하여는 그 구제가 필요하다 할 것 이므로 특허결정에 대한 행정소송의 허용 여부에 대하여 검토해 보았다. 아울러 행정법상 확인인 특 허결정의 직권 취소 내지 철회와 특허법상 구제방 법에 대하여도 검토해보았다.

        현행 「항만 및 어항 설계기준」 상 부두의 접안능력은 하기재화중량톤수를 사용하여 나타내고 있으나 접안가능 최대 선박의 결정에 영향을 미치는 요인은 재화중량톤수보다는 선박의 질량이나 길이 및 폭 등이다. 따라서 안전하고 효율적인 항만 운영을 위해 현재의 기준을 개선할 필요가 있으며, 이 연구는 합리적인 접안능력 기준을 제시하기 위하여 수행되었다. 부두의 적정 접안능력을 검토 하기 위하여 울산항의 3개 부두를 선정하고, 통항 및 접안 안전성과 선체동요 및 구조 안정성을 종합적으로 평가하였다. 배수톤수가 일정한 경우 선박의 크기가 다소 증가하더라도 선박조종이나 계류 및 구조 안전성에 미치는 영향은 미미하였으며, 검토 대상 선박에서는 선박의 크기에 따른 유의적인 차이를 보이지 않았다. 평가 결과 배수톤수에 차이가 없다면 20,000 DWT급 선박은 부두접안가능능력의 50%, 40,000 DWT급 선박은 25%, 그리고 150,000 DWT급 선박은 13% 정도 선박의 크기를 증가시키더라도 부두 축조시의 설계기준에 적합한 것으로 검토되었다. 따라서 항로폭, 선회장, 선석 길이 및 계류라인의 배치 등에 문제가 없다면 재화중량톤수 대신에 배수톤수를 적용하여 부두 접안가능 최대 선박을 조정할 수 있다.

        In this article a reliable and rapid method based on specific turbidimetry is proposed for the determination of sizes of nanoparticles. Conventionally in specific turbidimetry specific turbidities for a colloidal dispersion are measured as a function of light wavelength, and compared to theoretical values calculated from Mie scattering theory for presumed particle sizes. In contrast specific turbidity at a fixed wavelength is measured in the proposed method, and particle sizes are determined from the prepared calibration curve. The calibration curve is a plot of specific turbidity vs particle size and in this case the specific turbidities are measured for a couple of samples of known sizes.

        The magneto-transport properties of an individual single crystalline Bi nanowire grown by aspontaneous growth method are reported. A four-terminal device based on an individual 400-nm-diameternanowire was successfully fabricated using a plasma etching technique that removed an oxide layer that hadformed on the surface of the nanowire. Large transverse ordinary magnetoresistance (1401%) and negativelongitudinal ordinary magnetoresistance (−38%) were measured at 2K. It was observed that the period ofShubnikov-de Haas oscillations in transverse geometry was 0.074T−1, 0.16T−1 and 0.77T−1, which is in goodagreement with those of bulk Bi. However, it was found that the period of SdH oscillation in longitudinalgeometry is 0.24T−1, which is larger than the value of 0.16T−1 reported for bulk Bi. The deviation is attributableto the spatial confinement arising from scattering at the nanowire surface boundary.

        Recently, Korean shipbuilding industry is keeping up the position of world wide No. 1 in world shipbuilding market share. It is caused by endless efforts to develope new technologies and methods and fast development of IT technologies in Korea, to raise up its productivities and efficiency in shipbuilding industry with many kinds of optimizing methods including genetic algorithm or artificial life algorithm... etc. In this paper, we have suggested the artificial life algorithm with relay search micro genetic algorithm. and we have improved a defect of simple genetic algorithm for its slow convergence speed and added a variety of solution candidates with applying relay search simple genetic algorithm. Finally, we have developed intelligent agent system for ship CAE modeling. We have tried to offer some conveniences a ship engineer for repeated ship CAE modeling by changing ship design repeatedly and to increase its accuracy of a ship model with it.

        The amorphous (at%) alloy strip was pulverized using a jet mill and an attrition mill to get flake-shaped powder. The flake powder was mixed with dielectric powder and its dispersant to increase the permittivity. The powders covered with dielectric powders and its dispersant were mixed with a binder and a solvent and then tape-cast to form sheets. The absorbing properties of the sheets were measured to investigate the roles of the dielectric powder and its dispersant. The results showed that the addition of powders and its dispersant improved the absorbing properties of the sheets noticeably. The powder sheet mixed with 5 wt% of powder and 1 wt% of dispersant showed the best electromagnetic wave absorption rate because of the increase of the permittivity and the electrical resistance

        The electromagnetic (EM) wave absorption properties with a variation of crystallization annealing temperature have been investigated in a sheet-type absorber using the alloy powder. With increasing the annealing temperature the complex permeability (), permittivity () and power absorption changed. The EM wave absorber shows the maximum permeability and permittivity after the annealing at for 1 hour, and its calculated power absorption is above 80% of input power in the frequency range over 1.5 GHz.

        The purpose of this study is to analyse influential relevance of systematic, behavioral and environmental factors in deliberation for budget of the Gyeonggi Provincial councilors. A result of the analysis indicate that the council is formed mostly by members who are highly educated, newly elected and belong to the Hannara Party. Looking at the realities of the budget deliberation process, (1) inquiry period is short, (2) formation of the network collecting relevant information through regional connections (.81) is high, and (3) com·mon·place inquiry by questioning and answering (4) councilor's speaking that is based on political disposition, and (5) individual variation is big (6) deliberation ability (.37) that is required to slash the budget rationally through professional knowledge and effort is lacking. In order to solve, first, In view of the executives, establish a business program on the ground of result oriented performance principle. second, Period of the regular session should be extended and residents must elect members whose role awareness and public service spirit is high.

        The crystal structures and morphologies of precipitates in L10-ordered TiAl intermetallics containing nitrogen were investigated by transmission electron microscopy (TEM). Under aging at an approximate temperature of 1073 K after quenching from 1423 K, TiAl hardens appreciably due to the nitride precipitation. TEM observations revealed that needle-like precipitates, which lie only in one direction parallel to the [001] axis of the L10-TiAl matrix, appear in the matrix preferentially at the dislocations. Selected area electron diffraction (SAED) pattern analyses showed that the needle-shaped precipitate is perovskite-type Ti3AlN (P-phase). The orientation relationship between the P-phase and the L10-TiAl matrix was found to be (001)p//(001)TiAl and [010]p//[010]TiAl. By aging at higher temperatures or for longer periods at 1073 K, plate-like precipitates of Ti2AlN (H-phase) with a hexagonal structure formed on the 111 planes of the L10-TiAl matrix. The orientation relationship between the Ti2AlN and the L10-TiAl matrix is (0001)H//(111)TiAl and H//TiAl.

        The surface roughness of Al, Ag and Ni nano-powders which were prepared by pulsed wire evaporation method was quantified based upon the fractal theory. The surface fractal dimensions of metal nano-powders were determined from the linear relationship between In and Inln () using multi-layer gas adsorption theory. Moreover, the fractal surface image was realized by computer simulation. The relationship between preparation condition and surface characteristics of metal nano-powders was discussed in detail.
