  • Streamflow patterns at two gauging stations in Korea, An-Dong dam and Chung-Ju dam, are statistically analyzed in relation to EI Nino/Southern Oscillation (ENSO). As a measure of ENSO, the Southern Oscillation Index (SOI) is used on a monthly and seasonal basis. The traditional correlation analysis shows that cross correlations of the SOI with the seasonal streamflow are generally weak. To investigate the relationship between the extreme values of the SOI, which represent the EI Nino and La Nina events, and the corresponding streamflow patterns, the composite analysis is employed in this study. The composite analysis demonstrates that when EI Nino occurs, seasonal streamflows at An-Dong and Chung-Ju dams during the period from September of the EI Nino year to February of the following year appear to be drier than their means.

  • 본 연구는 P사의 사례를 바탕으로 사용중인 중역정보시스템(EIS : Excutive Informaiton System. 이하 "EIS"라함)에서 차별화된 회장전용 시스템의 개선에 대한 연구방법을 소개한다. EIS는 80년대 후반에서 90년도 초반에 이르기까지 급격한 성장을 이룩한 정보시스템이다. 그동안의 EIS가 도입과 보급 단계에서 양적인 성장을 이루었다면, 이제부터는 개선과 발전의 질적인 성장을 이룩하여야 할 필요성들이 점차 커지고 있다. 이러한 시점에서 P사의 EIS가 보다 더 나은 시스템으로 발전하기 위한 토대로, 본 연구는 회장전용의 차별화 된 시스템의 프로토타입을 구성하였다. 또한 본 연구에서는 멀티미디어 기술, 하이퍼미디어 및 슬라이드쇼를 이용하여 차별화된 EIS를 구축하였다. 시스템 구축을 위하여 다양한 아이디어의 도입을 통한 아이디어 기반의 시스템 개발과, 기존 EIS의 정보 전달 형태의 입체화 방안, 갱신 주기별 정보제공 및 전략차별 방안과 정보의 체계적 제공 방안을 근본 연구 추진 방향으로 하여 시스템을 개발하였다. 따라서 본 연구는 현재 개발계획중이거나, 개발중인 EIS에 새로운 접근 방법으로 도움을 줄 수 있을 것이다. 수 있을 것이다.

  • The purpose of this study was to investigate the relationships between parental childreating behaviors and parental personality, and children’s emotional intelligence. The subjects included 223 children from kindergarten to 6th grade and their parents. The results were as follows: Firstly, children’s Emotional Intelligence(EI) showed sex difference and age difference between two grade-groups(kindergarten~3rd grade, 4th~6th grade). the age-differences being more distinct in other-related EI than in the self-related : Secondly, parental personality explained parental childrearing behaviors better in higher-grade groups than in lower-grade groups, maternal personality predicting maternal childreating behaviors better than paternal personality predicting the paternal childreaing behaviors; Thirdly, childrearing behaviors explained childern’s self-relate EI better than the other-related : Finally, parental personality revealed greater predictive power of children’s EI in higher-grade groups than in lower-grade groups, better explaining sel-related EI than the other-related. Several suggestions were made concerning future EI studies.

  • Purpose: This study used a self-deterministic approach to explore the relationship between emotional intelligence (EI), academic motivation (AM), and achievement among health science students. Methods: A descriptive cross-sectional study was conducted in three cities of Saudi Arabia (Dammam, Riyadh, and Jeddah). A convenience sample of 450 students was incorporated using the multistage cluster sampling technique. The online survey contained three sections: students' basic data and academic achievement level, the modified Schutte self-report inventory, and the Academic Motivation Scale lowercase. Results: This study revealed moderate overall scores for EI (57.1%), AM (55.6%), and grade point average (GPA) (57.6%). The overall EI score, its domains, and GPA had significant positive correlations with overall AM and intrinsic and extrinsic motivation (p < .01). Amotivation had an insignificant correlation with GPA (p < .05), but it was negatively correlated with EI and its domains (p < .01). Multiple regression analysis proved that EI domains predicted 5.0% of GPA variance; emotions appraisal and expression (β = .02, p = .024), regulation (β = .11, p = .032), and utilization (β = .24, p < .01). EI domains also predicted 26.0% of AM variance; emotions appraisal and expression (β = .11, p = .04), regulation (β = .33, p < .01), and utilization (β = .23, p < .01). Moreover, AM predicted 4.0% of the variance in GPA; intrinsic (β = .25, p = .004) and extrinsic (β = .11, p = .022) motivation. AM also predicted 25.0% of the variance in EI: intrinsic (β = .34, p < .01) and extrinsic motivation (β = .26, p = .026). Conclusion: EI and AM have a bidirectional influence on each other, significantly shaping the GPA of health sciences students in Saudi Arabia, where intrinsic motivation has a predominant role. Thus, promoting students' AM and EI is recommended to foster their academic achievement.

  • In the MPEG-4 standardization phase, many methods for coding the irregular shaped VOP (video object Plane) have been researched. Texture coding is one of interesting research items in the MPEG-4. There are the Low pass extrapolation (LPE) padding, the shape adaptive DCT (SA-DCT), and the Extension-Interpolation (EI)/2D-DCT proposed in [1] as texture coding methods. the EI/2D-DCT is the method extending and interpolating luminance values from and Arbitrarily Shaped (AS) image segment into an 8 x 8 block and transforming the extended and interpolated luminance values by the 8x8 DCT. although the EI/2D-DCT and the SA-DCT work well in coding the As image segments. they are degraded since they use one-dimensional (1-D) methods such as the 1D-EI and the 1D-DCT in the two-dimensional (2-D) space. in this paper, we analyze the performance of the EI/2D-DCTand propose a new non-symmetric sig-sag scanning method, which non-symmetrically scans the quantized coefficients in the DCT domain to improve the EI/2D-DCT.

  • The present paper describes an analytic solution procedure for flexural vibration of a rotationally restrained hinged-hinged Timoshenko beam at the supports during an earthquake. Focusing on maximal magnitudes of internal loads such as bending moment and shearing force under wide variations of two parameters, kL/EI and kGAL2/EI, various beams under synchronous and asynchronous support motions are simulated. The simulations under asynchronous support motions show the following facts. The variations of the maximal magnitudes of internal loads of stocky beams due to the variation of kL/EI from zero to infinity show much wider variations than those of slender beams as kGAL2/EI decreases. The maximal magnitudes of internal loads of a beam tend to be governed by their static components as kL/EI increases and kGAL2/EI decreases. When the internal loads are governed by their static components, maximal magnitudes of internal loads of the stocky tend to increase monotonically as the value of kL/EI increases. However, the simulations under synchronous support motions show the static components of the internal loads vanish and the internal loads are governed by dynamic components irrespective of the two parameters.

  • 본 연구는 electron impact-gas chromatography/mass spectrometer (EI-GC/MS)를 이용하여 N-nitrosamines 분석하는 방법의 분리성, 정성 및 정량적 유효성을 평가하였다. 극미량의 검출을 위해 시료전처리는 자동고상추출과 질소농축과정을 거쳐 수행하였다. 표준시료를 전처리 없이 EI-GC/MS (SIM)와 EI-GC/MS/MS (MRM)를 이용하여 직접 분석한 결과, 두 방법 모두 유사한 감응도를 보였다. 반면, 전처리한 표준시료를 EI-GC/MS로 분석한 경우 불순물 피크에 의한 간섭영향에 의해 낮은 ng/L 수준의 정량은 어려운 것으로 나타났다. 8종의 N-nitrosamines에 대한 EI-GC/MS/MS 분석결과, 방법검출한계 및 정량한계는 각각 0.76~2.09 ng/L, 2.41~6.65 ng/L 수준으로 기존 분석방법에 비하여 낮게 나타났다. 첨가농도 10, 20, 100 ng/L에 대한 실험에서 정밀도(1.2~13.6%)와 정확도(80.4~121.8%) 모두 만족하였으며, 검량선의 직선성에 대한 결정계수($R^2$)도 0.999 이상이었다. 환경시료에 대한 대체표준물질(NDPA-$d_{14}$)의 회수율도 86.2~122.3%을 나타내어, 본 연구에서 평가된 방법으로 N-nitrosamines의 정밀분석이 가능함을 검증하였다.

  • The trend towards employee involvement (EI) has redefined the employer-employee relationship and, for many organizations, has brought about a fundamental change in organizational performance. This paper begins with a review of EI concepts and typologies. It goes on to elaborate need for the adoption of EI practices and discuss the factors affecting the adoption. The main theme of the quality management (QM) literature will then be presented addressing its concepts, principles and elements. Drawing on the theoretical and practitioners' perspectives, the paper also discusses the significance of integrating EI/QM practices to sustain organizational performance improvement.

  • Recently, EI nino and La nina phenomena have known as a cause of the unusual weather and meterological disasters in the world. The meteorological disasters in Korea have mainly caused by typhoons. In this paper, we studied the relationship between EI Nino and La Nina phenomena and the number of typhoons which have affected on Korea using the long-term data for the period from 1940 to 1999 (60 years) in case of normal years, EI Nino years and La Nina years, the numbers of typhoons which have affected on Korea are 3.1/year, 2.7/year and 3.9/year respectively. The number of typhoons which have affected on Korea in La Nina years is more than those in EI Nino years and normal years The occurrence rate of typhoon in La Nina years is also higher than those in EI Nino years and normal years.
