경기도 화성군 남양지역과 안산시 탄도지역에 분포하는 두 퇴적분지는 백악기(80-90Ma) 퇴적분지로서 10개의 암상과 5개의 상조합으로 구분된다. 상조합 I은 괴상 역암상, 정상점이층리 역암상, 역점이층리 역암상으로 구성되어 있으며 충적선상지에서 암설류와 판류에 의해 퇴적된 것으로 해석된다. 상조합 II는 괴상 이암상, 괴상 사암상, 엽층리 사암상, 괴상 역암상으로 구성되어 있으며 충적선상지와 망상평원 환경에서 판류와 부유 퇴적에 의해 퇴적된 것으로 해석된다. 상조합 III은 괴상 이암상, 엽층리 이암상, 괴상 사암상과 호층을 이루는 하도 역암으로 구성되어 있으며, 범람원에서 홍수시에 부유 퇴적과 하도 메꿈작용에 의해 퇴적된 것으로 해석된다. 상조합 IV는 괴상 역암상, 정상점이층리 역암상, 괴상 사암상, 정상점이층리 사암상, 엽층리 사암상, 호층을 이루는 이암상으로 구성되어 있으며, 선상지 삼각주에서 암설류와 저탁류에 의해서 퇴적된 것으로 보인다. 상조합 V는 괴상 이암상, 엽층리 이암상, 엽층리 사암상, 호층을 이루는 괴상 역암상으로 구성되어 있으며, 호수에서 부유 퇴적과 저밀도 저탁류에 의해 퇴적된 것으로 보인다. 남양분지에서 상조합 I은 분지의 동쪽과 남쪽 부분에 분포하며, 상조합 II는 남북의 대상 분포를 이루며 분지의 중앙부에 분포하고, 상조합 III은 분지의 서쪽부분에 분포한다. 탄도분지에서 상조합 II는 분지 동쪽 중앙부와 북서쪽에 분포하고, 상조합 IV는 분지 남서부에 그리고 상조합 V는 분지 중앙부에 분포한다. 상조합 대비는 남양분지에서 상조합 I과 II는 층서적으로 하부에 그리고 상조합 III은 상부에 분포하고, 탄도분지에서 상조합 II와 IV는 하부에 그리고 IV와 V는 상부에 분포함을 보여준다. 이러한 암상분포 양상은 남양분지는 처음에는 충적선상지와 충적선상지평원/망상평원이 교호하다가 범람원으로 발전하였으며, 탄도분지는 처음에는 선상지 삼각주와 충적평원/망상평원이 교호하며 발달했다가 나중에는 호수환경에서 발전한것으로 해석된다.

In the YBCO matrix, 10wt.% Y$_2$BaCuO$\_$5/ (211 phase) was added, the final 211 content of YBCO made by MTG process could reach about 20wt.% which was the optimum value for the critical current density. And also 10wt.% Ag was added in the matrix of YBCO, which was nearly about the saturate solubility of silver in textured YBCO. SmBaCuO crystal was grown by the melted-condensed process. A 5${\times}$5${\times}$2㎣ single crystal of SmBaCuO was used to be the seed in the preparation of YBCO. It was proved the orientation of YBCO was the same as the orientation of the SmBaCuO seed. The oxygen absorption of bulk oriented YBCO was studied and the heat treatment of oxygen absorption would be in flowing oxygen, at 400$^{\circ}C$ for about 24 hours. the magnetic hysteresis loops were measured by Vibrating Smaple Magnetometer and the J$\_$c/ was calcuated by means of Bean's model.

This study was conducted to demonstrate the differences in people's beauty involvement, hair attitude and cognitive in accordance with their interest in celebrities and television. Also, the difference between cognitive age and real age was studied. Research subjects were females aged 20s to 50s living in Seoul and the surrounding metropolitan areas. The SPSS 19.0 was used for data analysis. The results were as follows: First, the involvement in TV entertainers' was categorized into "TV entertainer fashion fan group," "TV entertainer follower group," and "TV program interest group." Second, The involvement of beauty was divided into skin management and expression, body management, makeup and hair attitude. The factors for hair attitude come from the following four actors: "hair creator fan group", "hair homeostasis-oriented," "hair differentiation factor," and "hair personnel-oriented group." Third, the analysis for the differences in the involvement of beauty based on the people's interest in TV appearances of entertainers was that there was a significant difference in skin care and expression, body management, makeup and hair attitude. The interest groups for the entertainers' TV appearances showed the highest in all of the above categories. Fourth, The analysis for the cognitive age for the "TV entertainer interest group" showed little difference in cognitive age, age of sensibility, age of physical appearance, behavior age, and age of interest. Fifth, The result for the difference in the actual age and cognitive age for different age groups showed that there was a little difference in average cognitive age including the age of sensibility, age of physical appearance, behavior age, and age of interest.

목적: 본 연구는 영국에서 개발된 컴퓨터 모니터용 검안프로그램 Test Chart 2000 Pro의 타당도(validity)를 평가하기 위해 수행되었다. 방법: Test Chart 2000 Pro와 한국표준검안법의 공통된 10종류 검안항목에 대하여, 각 항목별로 동일한 피실험자군을 대상으로 2가지 검안법을 함께 실시하고, 측정결과의 일치도를 비교분석하였다. 결과: 10종류의 비교실험 중 Snellen Chart, Cross-cyl Target, Duochrome Test, Fan and Block Test, Random Dot Stereograms에서는 한국표준검안법과 Test Chart 2000 Pro양측의 결과가 통계적으로 유의미한 일치를 보였으나, LogMar Chart, Single Letter Chart, Phoria Test, Fixation Disparity Test, Worth 4 Dot Test에서는 두 검안 방법의 결과에서 차이가 나타났다. 결론: 한천석 시력표와 포롭터로 이루어진 한국표준검안법을 기준으로 했을 때 Test Chart 2000 Pro의 타당도는 높지 않으며, 측정의 정확도 측면에서 개선이 요구된다.

A unique feature of fluidic atomizers is that the nozzle geometry produces a thin capillary Jet which is forced to oscillate on a 2-dimensional plane through the use of a passive feedback mechanism. The objective of the current work is to characterize the influence of the stagnation pressure at the nozzle exit, jet oscillation and stretching on the breakup properties of the capillary ligament. To achieve this, shadow graph technique is used to measure size, shape, velocity and the number density of the droplets as a function of the position within the spray fan. The breakup length, defined as the radial distance from the breakup point, is analyzed as a function of the non-dimensional parameters. Finally, a kinematic model is developed to simulate the breakup of the oscillating jets at low stagnation pressures. Using the existing jet breakup theories, the model is used to predict the size and diameter distribution of the droplets after primary atomization.

Recently, PMSMs(Permanent Magnet Synchronous Motors) have become increasingly popular in various high-performance motor drive applications. However, the high-performance drive of PMSMs needs a position sensor such as a resolver, which increases not only the price of the system but also reduces the system reliability. This paper is on the implementation of sensorless control of a SPMSM, which drives a fan for cooling in appliances. In this paper, the rotor position for high-performance drive of a SPMSM is derived from back electromotive force (EMF) information proportional to the rotor speed. Also, the initial rotor position information for start-up is estimated from a saturation phenomenon of inductance. The validity of the proposed sensorless drives was confirmed by the experiment on the SPMSM drive systems for cooling fans of refrigerators and laptop computers.

The purpose of this study is to investigate the impacts of e-service quality factors on customer satisfaction and behavior intention by Web site types. Difference and moderating effect resulting from the type of web site users about an association with reaction of satisfaction and those component concepts are also one of the aims in the study. As a result, the study found that factors of web site service quality variables had positive impacts on customer satisfaction. And customer satisfaction also had a positive impact on relationship intention and word of mouth intention. Furthermore, through the comparative analysis, we found that the service quality differed on the effects of customer satisfaction by web site types. According to those results, marketing managers should develop different service strategies based on different web site types.

본 연구의 목적은 얼굴 인식을 통해 사용자 위주로 작동하는 인공지능 선풍기를 개발하기 위한 것이다. 일반적인 선풍기는 사용자가 직접 풍향을 조절해야 하며, 조절한다 하더라도 사람이 위치하지 않은 곳까지 바람을 보내주거나, 사람이 없는 상황에서도 동작하는 비효율적인 방식이다. 따라서 본 논문에서는 OpenCV 오픈 소스 라이브러리를 중심으로 얼굴 인식 기능을 탑재한 선풍기로 PWM을 이용한 선풍기의 회전과 안드로이드 앱의 블루투스 모듈을 이용하여 원격조정이 가능하도록 하였다. 기존의 사용자가 직접 선풍기의 풍향을 설정해야 하는 것이 얼굴 인식이라는 시스템을 통해 자동으로 풍향이 조절되는 방식이다. 그 결과, 선풍기를 직접 설정할 수 없는 상황에 놓인 사람들에게 큰 도움이 됨과 동시에 불필요한 전력 낭비가 줄어드는 친환경 선풍기를 개발하였다.
