이 논문에서는 민족 존망의 위태로운 시기에 활동했던 안중근과 박영철이라는 두 사람을 통해 근대 지식인의 자세와 현실에 대한 대응 방식을 살펴보고자 하였다. 민족정신의 표상인 안중근과 친일파였던 박영철을 비교하는 것은 합당하지 않다고 말할 수도 있다. 그럼에도 불구하고 본고에서 그것을 시도한 것은 사회진화론이라는 똑같은 이데올로기라도 그것을 어떻게 적용시키느냐에 따라 결과는 판이하였기 때문이다. 안중근과 박영철은 같은 시기에 태어나서 개화기에서 일제강점기로 이어지는 변혁기를 살았다. 이들에게 민족 주권과 동양평화라는 공통적인 화두가 있었지만 삶의 방향이나 행적은 서로 달랐다. 전자는 일제의 심장을 겨누었고, 후자는 그것의 심장부로 들어갔기 때문이다. 이들은 동양평화에 대한 자신들의 견해를 19세기 이래로 대두된 적자생존과 우승열패로 귀결시키는 사회진화론을 전제로 개진하고 있었다. 게다가 이들의 논리는 사회진화론에 결합된 인종주의를 토대로 하고 있었다. 하지만 안중근은 동양 각국이 서로의 주권을 침해하지 않고 공존해야 동양평화가 이룩된다고 보았고, 박영철은 동양이 일본을 중심으로 뭉쳐야 동양평화가 이룩된다고 보았다. 이들 두 사람은 같은 시기를 살았지만 시대 의식도 대조적이었다. 안중근은 일제가 한국의 주권을 빼앗아 동양평화가 깨질 것으로 보았다. 반면에 박영철은 일본과 한국이 일체가 되어 대동아공영을 이룩한 바, 평화시대가 도래한 것으로 인식하고 있었다. 특히 후자는 한국의 주권보다는 일본의 근대 문명에 관심을 보이며 한국이 그것을 본받아야 한다고 보았다.

Moire topography method is a well-known non-contacting 3-D measurement method. Recently, the automatic 3-D measurement by moire topography has been required since the method was frequently applied to the engineering and medical fields. 3-D measurement using projection moire topogrphy is very attractive because of it s high measuring speed and high sensitivity. In this paper, using two-wavelength method of projection moire topography tested to measuring object with the $2\pi$-ambiguity problem. Experimental results prove that the proposed scheme is capable of finding absolute fringe orders, so that the $2\pi$-ambiguity problem can be effectively overcome so as to treat large step discontinuities in measured objects.

In modem industry, the accuracy and the surface-finish requirements for machined parts have been becoming ever more stringent. Optical method in measurements is playing an important role in vibration measurement, crack and defect detection and surface topography with the advent of opto-mechatronics. In this study, the principle of the general confocal microscope is introduced for surface measurement, and the advanced confocal microscope that has better measuring speed than the traditional confocal microscope is developed. A study on improving the resolution of the advanced confocal microscope is followed. Finally, Software for data acquisition and analysis of various parameters in surface geometrical features has been developed.

The holographic measurement techniques can be applied to various industrial fields such as automobile, airplane, construction, electronics, medical, mechanics and physics. The visualization of fluids is very important in aerodynamics, heat transfer and stress analysis. There are classically optical methods such as shadowgraph, schlieren method, and Mach-Zehnder interferometry for visualizing the fluid flow phenomena. But, it is difficult to understand the continuous state of fluids well in those methods. In this study, the real-time holographic interferometer with high-speed camera is applied to the flow visualization. In addition, collimated laser beam and rotating wedge are used for recording and formation of carrier fringes, respectively.

Recently, the study on the vibration analysis of machinery is greatly important and ESPI is widely used because of its many attractive features. Firstly, ESPI can be used to measure the vibration mode shape and the phase in real-time. Secondly, the conventional measuring methode, such as accelerometers, take much time to measure the whole field of object, but ESPI needs shorter time than other methods. Because ESPI is a field-inspection method. Thirdly, ESPI is a non-contact measuring system. ESPI does not have influence on the specimen. Beyond these features, there are several advantages in ESPI system. In this paper, the Stroboscopic ESPI system is described for measurement of a vibration mode shape. The Stroboscopic ESPI system had been used to visualize the vibration mode shape, in which EO(Electro-Optic)modulator was used to chop CW(Continuous Wavefront)laser. But it was not easy to control EO modulator and quantified the vibration amplitude and the phase of circular metal plate. At first, we found resonant frequency of the specimen by using time-averaged ESPI method. Nextly, the amplitudes of specimen were quantified by using Stroboscopic ESPI and we compare the results which were obtained in several chopping ratio.

최근 들어 지구온난화와 기상조건의 변화로 기후의 변동폭이 증가하면서 극심한 가물이 자주 발생하고 있다. 또한 기 개발된 용수원의 수질 오염, 물 분배에 관한 상류지역의 반대 및 지방자치단체간의 수리권 문제 등도 상류지역으로부터의 맑은 수자원 확보를 필요하게 만드는 요인이다. 따라서 이에 대한 용수공급 관리 방안의 필요성에 대한 인식이 부각되고 있으며, 수도권의 용수수요 변화에 대한 북한강 유역 댐의 용수공급 능력에 대한 적절한 검토가 필요한 실정이다. 본 연구에서는 북한강 유역 댐의 용수공급 가능성을 파악하고 적절한 용수 공급방안을 제시하기 위하여 shared vision 모형인 스텔라 소프트웨어를 이용한 모의 운영시스템을 개발하였다. 또한 이 모형에서는 수위에 따른 평균의 최소, 중간, 최대의 조건으로 3가지 Rule을 정하여 저수지의 운영곡선의 변화와 발전방류에 따른 안전 공급율 변화를 분석하였다.

Purpose: This study aimed to identify regional differences in problem drinking among adult males in single-person households and predict the determinants. Methods: This study used data from the 2019 Community Health Survey. Geographically weighted regression analysis was performed on 8,625 adult males in single-person households who had been consuming alcohol for the past year. The Si-Gun-Gu was selected as the spatial unit. Results: The top 10 regions for problem drinking among adult males in single-person households were located in the Jeju-do and Jeollanam-do areas near the southern coast, whereas the bottom 10 regions were located in the Incheon and northern Gyeonggi-do areas. Smoking, economic activity, and educational level were common factors affecting problem drinking among this population. Among the determinants of regional disparities in problem drinking among adult males in single-person households, personal factors included age, smoking, depression level, economic activity, educational level, and leisure activity, while regional factors included population and karaoke venue ratio. Conclusion: Problem drinking among adult males in single-person households varies by region, and the variables affecting each particular area differ. Therefore, it is necessary to develop interventions tailored to individuals and regions that reflect the characteristics of each region by prioritizing smoking, economic activity, and educational level as the common factors.

The aim of this study is to analyze the correlation between current intensity and amplitude of stimulus artifact on the cochlear implantee, and to find out basic information to check the device failure. Subjects were a prelingual child and 3 postlingual adults with more than severe hearing losses. The charge-balanced biphasic pulses were presented at stimulus rates of 11 pulses per second, each pulse width of $25{\mu}s$ with monopolar mode(MP1+2). Current intensities were delivered at 27.5, 33.7, 41.3, 50.5, 61.9, $75.8{\mu}A$. Stimulus artifacts were recorded by evoked potential system. This procedure was performed just before the initial stimulation, and then, the amplitude of stimulus artifacts were compared with each current intensity. The amplitude of stimulus artifacts was increased significantly according to the current intensity (p<0.01). The results suggest that the change of the amplitude of stimulus artifact can be used as a good cue to check the device failure in the cochlear implantee.
