골프활동 참여정도가 정서상태에 미치는 영향

조동진,이정규 한국스포츠리서치 2003 한국 스포츠 리서치 Vol.14 No.2

This study focuses on verifying the psychological effects among the roles of sport activities. To accomplish such a research goal, it analyzes the effects of participation in golf activity on emotional states such as anger, chaos, tension, fatigue and depression, the relationship between sport activity and psychological effect by providing the basic materials of emotional stability to the modern people, emphasizes the importance of psychological value in sport activities and then obtains the following conclusions. First, as a result of analyzing the emotional state according to the demographical variables, there is a significant difference in sex, age, monthly income and education; woman, the twenties, monthly income of one million won and middle and high school graduates were higher. Therefore, woman, young generation, low-income group and low education group showed negative emotional state and unstability. Second, as a result of analyzing emotional states between participation group and non-participation group in golf activity, participation group showed positive results in three factors such as anger, tension and fatigue and a significant difference. These results mean that sport activity, that is, golf activity has an affirmative influence on the emotional state. Third, the degree of participation in golf activity and period and frequency of participation showed a significant negative effects and the intensity of participation showed no significant difference. These results mean that 'the period of participation', that is, 'long and frequent participation' results in an affirmative result for emotional state and emphasize the importance of degree of participation in sport activities.

집합의 갯수가 서로 다른 Direct-Mapped 캐시 메모리의 효율적인 Trace-Driven 시뮬레이션 알고리즘

박동규,염흥열 순천향대학교 1994 논문집 Vol.17 No.3

In this paper, we propose a new trace driven simulation algorithm to evaluate the bus traffic and the miss ratio of the various direct-mapped cache memories, which have different number of sets, with a single pass through an address trace. Trace-driven simulation is usually used as a method for performance evaluation of cache memories, but it spends a lot of simulation time for simulating the various cache configurations with a long address trace. The proposed algorithm shortens the simulation time by evaluating the performance of the various direct-mapped cache configurations, which have different number of sets, with a single pass through an address trace. Our simulation results show that the run time of the proposed simulation algorithm can be considerably reduced than that of existing simulation algorithm, when the address traces obtained from the various sample programs are used as a input of trace-driven simulation.

Context를 고려한 확장된 GTRBAC Model

황유동,박동규 순천향대학교 부설 산업기술연구소 2004 순천향 산업기술연구소논문집 Vol.10 No.2

With the wide acceptance of the Internet and the Web, volumes of information and related users have increased and companies have become to need security mechanisms to effectively protect important information for business activities and security problems have become increasingly difficult. This paper proposes an improved access control model for access control enforcement in enterprise environments through the integration of the temporal constraint character of the GT-RBAC model and location constraints. The proposed model, called GT-RBAC(Extended Generalized Temporal Role Based Access Control) Model for context, supports characteristics of GTRBAC model such as of constraint, various time-constrained cardinality, location constraints, control flow dependency and separation of duty constraints (SoDs). Also it supports context characteristics by using location and time constraints in order to allow expressing access control policies at a finer granularity in corporate enterprise environments.

블럭 크기가 서로 다른 섹터 캐시 메모리의 실패율을 구하기 위한 Trace-Driven 시뮬레이션 알고리즘

박동규 순천향대학교 1994 논문집 Vol.17 No.1

In this paper, a new trace-driven simulation algorithm is proposed to evaluate the miss ration of the various sector cache memories, which have various sub-block sizes and block sizes and associativities and number of sets, with a single pass through an address trace. Trace-driven simulaton is usually used as a method for performance evaluation of cache memories, but it spends a lot of simulation time for simulating the diverse cache configurations with a long address trace. The proposed algorithm shortens the simulation time by evaluating the performance of the various sector cache configurations, which have various sub-block sizes and block sizes and associativities and number of sets. with a single pass through an address trace. Our simulation results show that the run times of the proposed simulation algorithm can be considerably reduced than those of existing simulation algorithms, when the proposed algorithm is implemented in C language and the address traces obtained from the various sample programs are used as and input of trace-driven simulation.
