The objective of this study was to determine the effective land units of communal forests for evaluating forest functions using GIS. As the candidates of the effective land units, we chosen the administrative units of parcels and 3 different scales of watersheds; small, medium and large. However, the administrative units of parcels were discarded because of the extreme complexity of ownerships and the highly petty scales of parcels. Instead, the 3 different levels of watershed units were applied to evaluating forest functions and the effectiveness of the resultant functional maps were compared each other in terms of the appropriateness or adequacy for field applications. According to the results of this study, it was found that the aggregated area by watersheds provides the appropriate scales of land area for forest functions and the small watershed is the most adequate one as the effective land units for forest functions in communal forests.

This paper presents the developments of Grid computing architecture which is use many data and resources from distributed and parallel system for construction test equipments, i.e., large scale computer networks meant to provide access to massive computational facilities for very large communities of users, drawing upon experiences of existing Grids architecture. In this paper, we present an efficient way to construct a construction test equipment infrastructure.

지금까지 방화벽 시스템에 대한 연구는 정보에 대한 접근을 최대한으로 제한하는 "기본 거부(Default Deny)"정책을 중심으로 연구되어 왔다. 그러나 대학 및 연구소와 같은 환경(이하 연구 환경)에서는 많은 연구 과제들이 동시에 수행되고, 또한 이러한 정보들이 외부와 공동으로 진행되는 경우에 정보를 공유할 뿐만 아니라 연구 결과를 외부에 공개할 필요성이 있다. 따라서 연구환경에 대한 보안정책은 기존의 기본 거부 정책보다는 정보에 대한 "개방성"이 요구된다. 따라서 본 연구에서는 연구환경에서, 정보의 공유 및 공개를 위한"개방성"을 충족시키기 위하여 역할 기반 보안정책(Role-Based Security Policy)을 이용한 방화벽 시스템을 제안한다. 역할 기반 보안 정책을 적용함으로서 방화벽 시스템 내무 사용자에 대한 보안 정책 적용이 가능할 뿐만 아니라, 방화벽 시스템 운용시에도 사용자의 역할 할당 및 변경 등의 보안 정책 변경이 가능하다. 역할 할당 및 변경 등의 보안 정책 변경이 가능하다.

In this study, we examined the effect of shared leadership on organizational trust, knowledge sharing, and innovative behavior. Also, it was verified that organizational trust and knowledge sharing play a mediating role in the relationship between shared leadership and innovative behavior. Data were collected from a survey of 348 manufacturing workers in Ulsan and Gyeongju. SPSS 22 was used for frequency analysis and exploratory factor analysis. AMOS 22 was used for confirmatory factor analysis to verify the validity of the variables and for covariance structure analysis to verify the research hypothesis. The results of this study are as follows. First, shared leadership has a significant positive effect on organizational trust, knowledge sharing, innovative behavior. Second, organizational trust has a significant positive effect on knowledge sharing and innovative behavior. Third, knowledge sharing has a significant positive effect on innovative behavior. Finally, organizational trust and knowledge sharing play a partial mediating role in the relationship between shared leadership and innovative behavior. The result of this study suggests that organizational trust and knowledge sharing should be strengthened through shared leadership in order to increase the innovative behavior of organization members.

The purpose of this study is to investigate the impact of leader-member exchange(LMX) on employees' creativity, and task performance focusing on the mediating effect of information sharing and job involvement. Based on the review of related references, we suggested our research model and hypothesis and then tested empirically. From these analyses, we can find some significant findings. First, LMX has a positive impact on information sharing. Second, information sharing has a positive impact on job involvement, creativity, and task performance. Third, information sharing has significant mediating effects on the relationship between LMX and job involvement, creativity, and task performance. Fourth, job involvement also has significant mediating effects on the relationship between information sharing and creativity and task performance. These results showed that information sharing and job involvement played their role as a meaningful mediator.

The purpose of this study was to explore predicting the factors affecting knowledge sharing behavior in SNS based learning community. Besides, participative motivation, openness to diversity, and knowledge sharing intention were included as predictors for this study. In addition, this study investigated the mediating role of knowledge sharing intention between participative motivation, openness to diversity and knowledge sharing behavior. 81 people in SNS based learning community participated in this study. Data collected were analyzed by correlation analysis, regression analysis and Baron & Kenny's(1986) mediation analysis. Results from this study, knowledge sharing intention and activity-oriented motivation predicted knowledge sharing behavior. In addition, knowledge sharing intention mediated among activity-oriented motivation, openness to diversity and knowledge sharing behavior.

스마트폰, 태블릿 PC 등 정보 기술의 급속한 확대로 주파수 수요가 증가하여 세계 각국은 모바일 데이터 트래픽 수용을 위한 주파수 확보에 노력하고 있다. 미국은 원활한 주파수 확보를 통한 초고속 광대역 통신망의 확충이 통신 분야에서 미래 국제 경쟁력 확보에 필수적이라는 것을 인식하고, 새로운 대역에서 모바일 주파수를 확보하는 노력뿐 아니라 기존 대역에서 1차 사용자를 보호하며 공유할 수 있는 공유 주파수 자원의 확보도 추진하고 있다. 주파수 공유를 도입하면 필요한 주파수를 짧은 기간에 경제적인 가격으로 확보 가능하다는 장점이 있다. 본고는 미국에서 주파수 공유를 위해 도입하는 최근의 스펙트럼 정책 동향에 대해 기술하고자 한다.

The concept of the sharing economy, which has shifted the economic paradigm from possession to access to resources, is consistent with the traditional and current roles of public libraries. Thus, this research empirically analyzed the influence relationships between public library use and the sharing economy. Results showed that participation in public library programs serves as a motivational factor for satisfaction with and trust in the sharing economy, while the use of public library facilities and equipment is correlated with attitudes toward and participation in the sharing economy. The use of library collections positively influences sharing intangible resources such as knowledge, information, and personal experience. By contrast, checking out library resources negatively influences the recognition of economic benefits from sharing, which is contrary to claims of library communities. Based on these results, public libraries should aim to have a complementary effect on the sharing economy founded not only on information networks but also human networks grounded in social relationships.
