역할기반 접근통제는 많은 조직에서 효과적으로 사용되고 있다. 역할기반 접근통제에서 권한은 역할과 관련이 되어 있고 사용자는 역할과 관련된 권한을 얻기 위해 역할의 일원이 되어진다. 역할기반 접근통제에서의 사용자 권한위임은 한 사용자가 인증 된 다른 사용자에게 자신의 권한을 위임하여 권한을 위임 한자신과 같은 역할의 일원이 되게 하는 것이다. 그러나 기존의 역할기반 접근통제 모델에서는 권한의 일부를 위임하는 것이 어려웠다. 본 논문에서는 역할을 위임을 위한 부분역할로 나누어 권한의 일부를 위임 가능하게 함으로써 권한 전체를 위임했을 때의 문제를 방지하고, 접근통제에서의 최소권한 원칙과 임무분리 원칙을 만족하게 하는 권한위임 방법을 제안하였다.

권한위임은 역할기반-접근통제에서 중요한 정책의 하나로 한 역할에서 다른 역할로 권한의 일부 또는 전부를 위임하는 것을 말한다. 대부분의 계층적 역할기반-접근통제 시스템에서는 권한위임 시에 회수까지 고려한 위임을 지원하는 모델이 일반적이다. 하지만 권한위임에 있어서 역할권한의 회수가 불필요하거나 회수를 할 때 문제가 발생할 수 있다. 본 논문에서는 역할권한의 회수가 필요하지 않는 경우에 시스템의 복잡성을 감소시키기 위한 방안으로써 단방향 권한 위임 기법을 정의하며, 일반적인 위임과 단방향 권한 위임이 같이 고려된 하이브리드한 위임 기법을 제안한다.

The purpose of this study is descriptive survey to menstrual difficulties and coping experience in adolescents. The health locus of control(HLOC) was shown in the internal HLOC, powerful other HLOC, and chance HLOC. Coping types appeared active behavioral, active cognitive, and avoidance. The finding showed that the influencing factors were internal HLOC, menstrual discomfort, and hospital visits, and the explanatory power for this 11.7%. Further research is needed considering the lifestyles of students.

The purpose of this study was to propose basis data to nursing intervention development in order to raise the professional consciousness of long-term care workers grasping influence factor and professional consciousness. The subjects were about 185 long-term care workers at D megalopolis and 4 cities of 3 provinces from November to December, 2009. The data were analyzed using the SPSS program for descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients and multiple regression. The correlated factors of professional consciousness included self-efficacy(r=.420, p=.000), sense of the calling(r=.636, p=.000), education training effectiveness(r=.441, p=.000), internal locus control(r=.378, p=.000), and external locus control(r=-.356, p=.000). Factors influencing of professional consciousness of them were to show in order of sense of the calling(B=.329, p=.000), education training effectiveness(B=.250, p=.000), internal locus control(B=.216, p=.000), external locus control (B=-.165, p=.002), consideration and opplicable job choose characteristic(B=.207, p=.004), these variables accounted for 57.5% of the variance of professional consciousness. Further research needs to develop well organized educational program, training of enhancing internal locus control, and clear examination about roles and tasks of long-term care workers. Also, it suggests education and research that can enhance professional consciousness by utilizing these factors.

This study was conducted to identify the factors related to the cancer preventive behaviors of middle aged women. The data was collected from October $1^{st}$ 2012 to February $10^{th}$ 2013 from 114 middle aged women in four churches in B city. As a result, there were significant differences in the cancer preventive behaviors according to cancer preventive education, concerns about cancer information and the utilization of cancer information. The cancer preventive behaviors were weakly related to the internal health locus of the control, chance health locus of the control and self-esteem. In addition, there was moderate correlation between the cancer preventive behaviors and the external health locus of the control. Meaningful variables that explain the cancer preventive behaviors were the external health locus of the control, self-esteem, cancer preventive education in that order. The total explanation power was 25.3% and the external health locus of the control has most explanation power. In conclusion, it is necessary to develop nursing intervention and health education for middle aged women to raise the internal health locus of the control and self-esteem, and encourage attending cancer preventive education to improve the preventive behaviors against cancer.

This study was conducted to investigate the effects of a career preparation program (CPP) on self-leadership (SL) and career locus of control (CLOC) among University Students in South Korea. Self-leadership is the ability to control and lead oneself to achieve goals. CLOC is that attribute own's success of failure to own's effort and ability internally or luck or environment externally. Both have been known to strongly affect variables associated with career planning. We also explored SL and CLOC based on the variable related subjects' characteristics. Method: After receiving informed consent, 58 subjects were collected from University in D metropolitan area in Korea from March to June 2016. CPP was provided to college students who agreed to join this study, which consisted of a 15 week career development program. During the program, recruitment information was provided as well as encouragement and motivation. The program also focused on self-exploring and self-initiating experiences by themselves. Data were collected before and post CPP and were analyzed using SPSS 21.0. Result: self-leadership increased from $3.02{\pm}0.36$ points to $3.23{\pm}0.35$ points after CPP (t=-4.45, p=0.00). There were significant differences in self-leadership and in internal attribution (t=-3.26, p=0.00). The CPP based on the understanding of oneself was effective to cultivate university students' self-leadership. Moreover, the CPP increased internal attribution of the college students significantly from $2.96{\pm}0.35$ points to $3.15{\pm}0.32$ points (t=-3.26, p=0.00). CPP was also found to effectively influence the internal locus of control. Although external attribution was reduced from $2.19{\pm}0.31$ to $2.13{\pm}0.35$, this different was not significant (t=1.68, p=0.09). Conclusion: The results of this study suggest that the CPP based on understanding of oneself should be actively applied in career education.

RBAC is an Access Control Mechanism for security administration of system resource and technique attracting in commercial fields because of reducing cost and complexity of security administration in large network. Many RBAC's research is progressive but several problems such as the delegation of role have been pointed out concerning the mechanism. It is necessary that a person's role delegate someone with reliability by reasons of a leave of absence, sick leave and the others. But the existing RBAC standards don't give definition of the delegation of roles. In this paper, we propose RBAC model that delegator can delegate subset of role and permission to a delegatee so that more efficient access control may be available.

이론적으로 하천의 흐름은 시간과 위치에 따라 수위와 유량의 관계가 일대일로 대응한다는 가정을 두지만, 실제 하천은 여러 가지 통제요인에 의해 다양하게 변화한다. 특히 하천 상 하류 일부구간에서 인공적인 골재채취나 준설작업과 같은 하도공사가 이루어진다면 하천의 흐름은 일시적인 수위변화가 아닌 단면의 변화 나아가 수위에 따른 유량의 증가 및 감소를 일으키게 된다. 또한 모래하상이나 식생의 영향을 받는 하천의 경우에도 빈번한 단면 및 유속의 변화를 볼 수 있다. 본 연구에서는 2007년부터 2011년까지 유량조사사업단에서 측정이 이루어진 4개 수계 577개 지점을 대상지점으로 선정하고, 이들 중 2개년 이상 측정이 이루어져 단면변화 및 지점의 수리특성 여부를 비교할 수 있는 한강 55개, 낙동강 49개, 금강 43개, 영산강 55개 지점의 수위-유량관계 변화여부를 검토하였다. 본 연구는 경년변화 없이 일정한 수위-유량관계를 보이거나 보와 같은 단면 통제에 의해 단순한 기간분리가 발생되는 지점, 4대강 공사가 진행 중인 지점, 미미한 단면변화에 의해 저수위의 수위-유량관계가 변화된 지점들은 분석 대상에서 제외하고, 중수위 이상에서 수위와 유량의 관계가 변화하는 지점들을 찾아 그 원인을 파악하고 사례를 분석하는데 중점을 두었다. 검토 결과 중수위 이상에서 수위-유량관계가 변화되는 요인으로 크게 상류와 하류에서 하천준설을 실시하여 수위에 따른 에너지선의 증가 및 감소를 일으킨 경우와, 제방공사에 의해 고수위가 변화가 발생되었거나 그 해에 배수영향을 받았는지 여부 또는 하도에 자생하는 식생의 영향 그리고 모래 및 자갈하천에서 발생되는 큰 단면변화 등으로 나타났다.

Recently, hand washing has been emphasized as Middle East Respiratory Syndrome Coronavirus (MERS) threatened public health. This study aimed to prevent MERS by hand washing frequency and analyzed the relationship between hand washing behavior and trait anxiety, locus of control and health promotion behavior. In this study, 314 nursing students participated in a survey where they could indicate what they did and the frequency of hand washing for preventing MERS. They also responded to questions related to the trait anxiety, locus of control, and health promotion behavior. The data were analyzed using descriptive statistics, Pearson correlation, and multiple regression. The frequency of hand washing was highest among the measures that the participants used and it was significantly related to the participants who reported high scores for the importance of hand washing. In addition, the importance of hand washing was impacted by the internal locus of control. Most nursing students who participated the survey acknowledged that hand washing was the most important method for preventing MERS. Therefore, it is important to educate people on the importance of hand washing and pay attention to personal characteristics, such as internal locus of control to promote hand-washing.
