예술영화와 상업영화는 영화라는 공통의 대중문화양식에 속하면서도 상이한 특성을 나타낸다. 본 연구는 영화를 예술영화와 상업영화로 구별하여 비평의 전문성과 사전 기대가 관람 의도의 미치는 영향에 대해 알아보았다. 이를 위해 20-30대의 일반인을 대상으로 설문조사를 진행하였다. 그 결과, 예술영화와 상업영화라는 영화 유형별로 비평의 전문성과 사전 기대가 관람 의도에 미치는 영향에 차이가 있음이 확인하였다. 예술영화의 경우 비평의 전문성이 높았을 때 관람 의도가 높아졌으며 이는 비평의 전문성에 의해 형성된 실용적 기대감이 비평의 전문성과 관람 의도와의 관계에 매개효과를 가졌기 때문임을 검증하였다. 반면 상업영화의 경우 비평의 전문성이 낮았을 때 관람 의도가 높아졌는데, 이는 비전문가인 일반 네티즌의 비평에 의해 형성된 정서적 기대감이 둘 사이의 관계에 매개효과를 가졌기 때문임을 검증하였다. 결론적으로 본 연구는 비평가의 전문성이 영화의 유형에 따라 일반대중의 관람 의도에 상이한 영향을 미친다는 것을 밝힘으로써 영화 산업의 연구에 공헌하고자 한다.

네트워크 장비의 데이터 처리 속도와 용량이 급속하게 향상되면서 기존 단일 프로세서로는 데이터 처리 성능에 한계에 이르고 있다. 즉, 하나의 CPU에서 Unit에 대한 Management 기능에서 Data Processing 등 모든 기능을 수행할 경우 데이터 처리 속도와 용량에 제약이 따르게 된다. 이를 보완하기 위해서 하나의 프로세서는 Unit Management 기능만을 처리하고 다른 하나 이상의 프로세서에서는 Data Processing 관련 기능을 전담하여 시스템의 안정성과 많은 데이터를 보다 빠른 시간에 처리할 수 있는 신뢰성에 초점을 맞추고 있다. 본 논문에서는 이종 OS로 구동되고 있는 Dual CPU 기반에서의 S/W Watch-Dog 기능을 제안한다. 즉, 상이한 OS를 사용하는 2개의 프로세서로 구성된 Unit에서 프로세서간 통신 장애나 프로세서 Down 등을 감시/감지하는 방법에 대해 제안하고, 제안한 방안에 대해 S/W Watch-Dog 기능의 신뢰성을 극대화 할 수 있는 요소(임계 시간, 우선순위)의 최적 값을 시험 및 분석 Tool을 사용하여 찾아내고, Data Rate에 따른 S/W Watch-Dog 기능의 정확성을 향상시킬 수 있다.

Objective: This study aims to identify the most effective keyboard layout in the area of performance for securing usability in a smart watch-using environment and to verify the usability of touch keyboard calibrated by hand. Background: It is necessary to understand the environmental characteristics in using the smart watch and to secure the usability of touch keyboard based on this understanding in order to take account of the users who use the touch screen in the extreme input conditions caused by the small screen of a smart watch. Method: 30 participants in this study were required to input characters using the QWERTY keyboard and 3x4 keypad (Naratgul, Chunjiin), which were familiar with them, in order to grasp the keyboard layout suitable in the smart watch- using environment; the performance (error rate, performance time) of this case was measured. In addition, 30 participants in this study were required to input the characters setting the QWERTY keyboard with calibrated touch area and the one with uncalibrated touch area, based on the characteristics of touch behavior, by finger typing the keyboard, with the performance (error rate and performance time) of this case measured.

This study has focused on manufacturing technique of powder injection molding of watch case which made from zirconia powder. A series of computer simulation process was applied to prediction of the flow pattern in the inside of the mould and defects as weld line. The material properties of melted feedstock inclusive of the PVT graph and thermal viscosity flowage properties were measured for obtaining the input data in computer simulation. Also, molding experiment was conducted and the results of experiment showed that good agreement with simulation results far flow pattern and weld line location. On the other hand, gravity and inertia effect have an influence on velocity of melt front because of high density of ceramic powder particles in powder injection molding against the polymer injection molding process. In the experiment, the position of melt front was compared with upper gate and lower gate position. The gravity and inertia effect could be confirmed in the experimental results.

다양한 산업 영역에서 향수 마케팅이 활발히 전개되고 있다. 영화 산업에서도 향수라는 주제는 새로운 트렌드를 형성하고 있다. 본 논문에서는 향수를 중심으로 기대 및 평가가 영화 관람의도에 미치는 영향에 대한 실증적 분석을 시도하였다. 향수는 과거의 장소나 시간을 그리워하는 감정이다. 기대는 실용적 기대와 정서적 기대로 나누어지며, 평가는 객관적 평가와 주관적 평가로 구분된다. 본 논문에서는 이 다섯 가지요소가 영화 관람의도에 미치는 영향을 분석하였다. 연구 결과 높은 연령이 낮은 연령보다, 여성이 남성보다 향수가 높게 나타났다. 연령별로는 10~20대는 정서적 기대 주관적 평가 향수 순으로, 30대 이상은 정서적 기대 향수의 순으로 영향을 미치는 것으로 나타났다. 성별로는 남성의 경우 정서적 기대 향수 주관적 평가 순으로, 여성의 경우 정서적 기대 주관적 평가 순으로 나타났다. 이러한 결과는 연령과 성별에 따라 마케팅 전략이 달라져야 함을 시사하고 있다.

The aerosol characteristics in terms of 4 different cases (Asian dust, fog, clear sky and cloud) which had happened at Anmyeon Island in April 2006 were studied using various measurements such as the Micro Pulse Lidar (MPL), sunphotometer, $\beta$-ray $PM_{10}$ Analyzer, anemoscope and anemometer. In addition, synoptic charts, back trajectory analyses and satellite images were also used to help characterize the aerosol events. The aerosol optical properties were featured by the Aerosol Optical Depth (AOD) and ${\AA}ngstr\ddot{o}m$ exponent which were estimated by the sunphotometer. When Anmyeon Island was dominated by the Asian dust, the AOD was sharply increased as seven times as a yearly average of it (0.35). As compared with a yearly average of the ${\AA}ngstr\ddot{o}m$ exponent of 0.97, the ${\AA}ngstr\ddot{o}m$ exponent of a dust day was significantly low (0.099). In addition, $PM_{10}$ mass concentration showed an extremely high record. The maximum concentration reached $1790.5{\mu}gm^{-3}$ on 8 April 2006. The maximum mass concentration was shown with delay when the wind speed of $0ms^{-1}$ was observed. It was also found that a satellite image of the MODIS-RGB had a good agreement with the results of those measurements. It was shown that the MPL was able to describe effectively the vertical distribution of aerosol for all the cases. In particular, the MPL evidently captured the aerosol layer before the cloud observation. The aerosol layer was similarly described by the AOD. On a clear sky day, the AOD had not only a very low value (0.054) but also a feature of homogeneity.

The extreme heat watch warning system(EHWWS) that Korea Meterological Administration carried out a preliminary from July 1, 2007, considered both daily maximum temperature and daily maximum heat index simultaneously. It was requested revision of the standard level of EHWWS to solve the difficulty of forecasting occurred when we were considering two parameters simultaneously and we did not considering heat index according to areas. For this, we established three type standard, such as type 1 that considered both daily maximum temperature and daily maximum heat index, Under the extreme heat day that daily minimum temperature was more than $25^{\circ}C$, type 2 that considered daily maximum temperature and type 3 that considered only daily maximum heat index and then analyzed whether these 3 types satisfies the excess mortality of the extreme heat warning or not. As a results, type 1 and 2 were more explain away excess mortality each warning step than type 3. type 2 could also apply case of not to consider heat index according to areas and had a merit for extreme heat forecasting easily because the standard was simple. Therefore we think type 2 is more suitable and reasonable standard for Korea extreme heat watch warning system(KEHWWS) than type 1. In addition, we need to develop model that exactly predicts the excess mortality will be take place during the extreme heat warning and construct KEHWWS.

In the case of a automobile marking skid on road for a period of braking, in general, the automobile velocity just before rapid braking can be obtained by evaluating the coefficient of friction between tires and road. Up to now, the coefficient of friction has been derived from mean velocity measured by a time watch, but the automobile velocity obtained in this manner would be deviated from actual value considerably, due to errors arising from not only measuring time but other various factors. In this paper the presumption method of automobile velocity by accelerometer is presented so as to improve the accuracy of measurement, and to determine the velocity readily. The results obtained in this experiment show that the frictional coefficients between tires and road under the given experimental conditions are considered to take linear relation over the fixed velocity limits 30km/h to 50km/h while for the same limits of velocities the coefficients of friction by the time watch method are not valid ar low velocity range. It will be seen that the former is simple and reliable whilst the latter is cumbersome and unreliable.
