Multiprocessor architecture becomes increasingly common on real-time systems as computer hardware technology rapidly progresses and the workload of real-time systems increases. However, efficient solutions for many real-time multiprocessor scheduling problems are not known. Hence many researchers apply uniprocessor scheduling algorithms to multiprocessor scheduling or devise new algorithms based on these algorithms. Such algorithms are EDF (Earliest Deadline First), LLF (Least Laxity First), EDF-US[m/(2m-1)], and EDZL (Earliest Deadline Zero Laxity), and comparative studies on them are necessary. In this paper, we show the dominance relation of these algorithms with respect to schedulability, and we prove EDZL strictly dominates EDF. The simulation results show that EDZL has high processor utilization and it causes a small number of preemptions.

Two experiments were conducted to examine whether the word superiority effect (WSE) can be affected by visual familiarity of Hangout font and visual identicalness between target letter and test letter. In experiment 1, Using Batang-font as a target font, it was tested whether the consistency between test font and target font could affect the WSE across different display time conditions. In experiment 2, using the Batang-font and Sebeul-font, the effort of visual familiarity on WSE were investigated. The results revealed that the WSE was found regardless the consistency between target and test letter. In addition, it was found that visual familiarity could affect overall detection rate, but not WSE. These results suggested that the WSE on Hanguel is independent of visual properties.

Issues of how firms form collaborative inter-firm alliances, how they nurture the alliance relationships as meaningful ones, and how they evolve and manage collaborations in turbulent market environments deserve increasing research attention. To contribute to filling this void, this study conceptualizes an alliance orientation as a firm's capabilities to help achieve an advantageous alliance performance to its rivals and based on this concept, demonstrates specific process for a successful alliance performance. First, this study empirically explores the influence of a new construct, alliance orientation, on firms' alliance performance. Second, the concept of alliance creativity as a positional mediation variable between alliance orientation and market performance is explained and then empirically explored. Third, alliance performance as a mediator between alliance orientation and market performance is presented and then is empirically reviewed.

This study was conducted to investigate the relationship between contingencies of self-worth(superiority and others' approval), college adjustment and expectancy for future success and the mediating role of cognitive flexibility in these relationships. For this study, data from 460 college students were analyzed. The results were as follows. Contingencies of self-worth(superiority) were positively associated with college adjustment and expectancy for future success, while contingencies of self-worth(others' approval) were negatively associated with college adjustment and expectancy for future success. Second, the results of structural equation modeling indicated that cognitive flexibility fully mediated the relationship of contingencies of self-worth (superiority and others' approval) with college adjustment and expectancy for future success. Third, even the contingencies of self-worth(other's approval) were negatively associated with cognitive flexibility, and if the latter was high, it influenced college adjustment and expectancy for future success. Finally, the meanings and limitations of this research and implicationsfor counseling strategies and interventions were discussed in detail.

금융가격별 지표의 변동성 증가에 대처하려는 보수적 투자가들이 이용할 수 있는 매력적 방안의 하나가 보험부 투자기법이다. 그러나 이 투자유형은 설계에 상당한 신축성을 보이며 이는 동시에 투자성과 구조의 신축성으로 반영된다. 주요한 설계차원의 하나가 위험투자의 손실발생시 보상차원이다. 여기에 일반적 보험개념을 적용할 때 투자가가 직면하는 선택문제의 하나는 부분보험계약형 투자설계시 공제부보험형 전략과 공동보험형 전략간의 선택이다. 일반적 보험 이론에서는 전자가 후자에 대해 우월한 유형이라는 것이 밝혀져 있다. 본 연구는 이를 보험부투자에 응용할 때도 양 전략간에 어떠한 우월관계가 존재하는 지 알아보려 시도했다. 이를 위해 효율성 평가기준의 하나인 간편한 확률적 지배기준을 적용하였으며 분석결과는 생산적이었다. 두 전략 각각의 기대수익률의 확률분포를 대상으로 기대수익률이 상대적으로 공제부보험형 전략에서 공동보험형 전략에서보다 상대적으로 높거나 최소한 같은 경우에 전자가 후자를 지배하며 그 반대조건인 경우에는 양 전략간에 우열관계가 나타나지 않는다는 결과를 얻었다.

This study reflects the regional context of Northeast Asian countries embodied in US-North Korean nuclear tension. The researcher uses the methodological inquiry of practical theology to analyze the political affairs and intertwine with religious education. The ecology of religious education to dismantle the threat of ethnic and racial discrimination such as white supremacy supports a shared pedagogy between students and their teachers in the narrative of Jesus to challenge all forms of oppression as the democratic presence of God.

본 연구에서는 회전 원통형 마그네트론 스퍼터링 시스템(Cylindrical Magnetron Sputtering)을 이용하여 성막한 Sn-doped $In_2O_3$ (ITO) 투명전극의 두께 변화에 따른 전기적, 광학적, 구조적 특성을 연구하였다. 회전 원통형 마그네트론 스퍼터링 시스템을 이용한 ITO 투명전극은 박막의 두께가 50~1,000 nm의 두께로 증가함에 따라 비저항 값은 일정하게 유지되나 면저항 값이 $37.8{\Omega}$/square로부터 $1.5{\Omega}$/square로 점차적으로 감소됨을 확인할 수 있었다. 또한 ITO 박막의 두께 증가가 50 nm에서 1,000 nm로 증가함에 따라 400~800nm 파장 범위에서 71~83％의 높은 광투과도를 나타내었다. 두께 변화에 따른 광학적 특성 변화를 설명하기 위해 Spectroscopic ellipsometry 분석을 실시하였으며 이를 기반으로 박막 두께와 투과도의 상관관계를 설명하였다. 한편, 원통형 마그네트론 스퍼터로 성장시킨 ITO 박막은 두께가 50~200 nm의 범위에서는 (222) 방향으로 우월 성장하였으나, 200-1000 nm 두께 범위에서는 우월 성장방향이 (400)과 (622)로 바뀜을 X-ray diffraction (XRD) 분석을 통하여 확인하였다. 이를 통해 박막의 두께변화에 따른 전기적/광학적 특성의 변화는 박막의 구조와 매우 밀접한 상관관계가 있음을 알 수 있었다.

재무경제학에서 많은 연구들이 주식가격과 거시경제활동과의 이론적 모형을 설정하고 이를 점증하고자 하였다. 이 분야에서 지금까지 주로 ARMAX 모형이나 VAR 모형들이 사용되어 왔으나, 이러한 방법들은 주식가격과 거시경제변수들간의 장기적인 균형관계를 파악할 수 없다는 한계점을 안고 있다. 따라서, 본 연구의 목적은 이러한 한계점을 극복할 수 있는 VECM을 이용하여 우리나라 증권시장과 거시경제변수들간의 장기적인 균형관계를 규명하고자 함에 있다. 검증결과, 모든 변수들의 시계열이 불안정적인 것으로 확인된 관계로, 다변량시계열의 공적분 관계를 검증하는 Johansen 검증을 VECM 모형의 구조 안에서 실시하였다. 종합주가지수와 거시경제변수들간에는 장기적 안정관계를 나타내는 공적분관계가 있는 것으로 나타났으며, 종합주가지수와 거시경제변수들간의 관계는 대부분 이론적인 관계에서 예상하는 부호와 동일한 부호를 갖으며 통계적으로도 유의하였다. 그리고, VECM의 설명력이 종래에 주로 사용하였던 VAR 모형의 설명력보다 더 우월하게 나타났다.
