Recently, the efficient management system for large-scale sensor data has been required due to the increasing deployment of large-scale sensor networks. In previous studies, sensor data was managed by distributed database system which built in a single server or a grid server. Thus, it has disadvantages such as low scalability, and high cost of building or managing the system. In this paper, we propose a cloud-based sensor data management system with low cast, high scalability, and efficiency. The proposed system can be work with the application of a variety of platforms, because processed results are provided through REST-based web service.

In the situation where the uncertainty of the environment of organizations is high and dynamic, the competitive advantage should be secured and maintained through securing knowledge-based intangible assets rather than tangible assets. human resources management in the service industry is more important than in any other industries. Accordingly, based on preceding researches, this study examines the adoption factors and the results of organizations with regard to the e-HRM system as IT-based information system. The proof results are summarized as follows. First, the degree of IS maturity in the information technology factors was found to have effects on the business results of organizations (financial and non-financial results) and the IS/IT based structure was found to have significant effects on financial results (productivity, growth potential) but no effects on non-financial results (revitalization of organizations, the degree of total satisfaction). Second, the degree of competition, the degree of information technology and environmental uncertainty factors in environmental factors were found to have effects on financial results (productivity, growth potential) but no effects on non-financial results (the revitalization of organizations, the degree of total satisfaction). Third, it can be seen that the scales of organizations partially play the adjustment role between information technology factors and environmental factors and the business results of organizations. Based on these results, we can cautiously draw the conclusion that it is effective in enhancing financial results (productivity, growth potential) of organizations to adopt the e-HRM system in the case of large scale organizations in the service industry.

The greatest mission of archival community lies in collecting records to document past and present Korean society and in safeguarding them to pass over to the next generation. For the last decade, Korean archival community has actively pursued this mission and accomplished it to the certain extent. A series of events occurred during the last year urged the community to regretfully accept that the so-called accomplishment was by no means satisfactory. The present study aims to review what has been achieved against what should be if the community is to be truthful to the fundamental mission. It begins with addressing attributes of electronic records. To be specific, attributes of electronic records as 'records' are compared against those as 'digital objects.' Current state of long-term preservation of electronic records is reviewed. Suggestions follow in terms of four directions: establishing a policy framework based on principles of electronic records management, building integrated electronic records management system, researching and developing functionalities for long-term preservation, and finally, knowledge transfer and coordination.

Robots have limited computing resources and robot services have different requirement such as sensors, actuators, computational capabilities and timeliness. In this paper, we propose a dynamic management method of service execution contexts to perform various services efficiently and to meet the time constraint of service in network-based robots. The proposed method is tested in the real network-based robot system. The results show that the real-time requirement for services is satisfied and the resource utilization is improved. The proposed method provides the extendability and flexibility of sensors and services by aptly modifying service execution contexts and increases the reusability of service.

농가인구의 감소 및 고령화, 고소득 작물 재배, 기후변화 등으로 인해 영농형태가 논농사에서 밭농사로 전환되고 지역별 증감의 차이가 있기는 하나 밭 면적이 증가하는 추세를 보인다. 한편, 밭작물은 논에 비해 기반시설이 부족하고 고소득의 밭작물을 생산하기 위한 시설재배가 늘어나면서 대부분 사계절 확보가 용이하고 수질이 양호한 지하수를 사용하고 있다. 지하수 수요 증가는 지하수위 저하와 지하수 고갈의 우려를 초래하고 있다. 본 연구에서는 농업용 지하수 이용 실태를 분석하고 지하수이용 및 관리 제도 현황을 검토하여 지속가능한 밭용수 공급을 위한 지하수 관리전략을 제안하였다. 진주시를 대상으로 경지유형에 따른 지하수 이용 특성 분석하여 지하수의 수요 특성을 살펴보았는데, 하천 주변 저지대에 큰규모의 밭이나 집단화된 시설재배 지역이 분포하고 있고 지하수 관정도 밀집하고 있었다. 하천에서 떨어진 산간지역에는 지하수 관정이 산발적으로 분포하고 있었다. 지하수 수요는 공간적 위치 외에도 고품질 농업용수에 대한 요구도 원인인 것으로 조사되었다. 밭기반 용수공급 관련 사업과 지하수 자원확보 관련 법제도 등을 고찰하여 밭의 위치, 규모, 용수공급의 수요 특성 등을 고려하여 밭용수 공급을 위한 세 가지 지하수 관리전략을 제안하였다. 우선, 농업용 지하수 이용량 실측 및 정보의 다각화를 통한 정보의 고도화가 필요하다. 둘째, 지하수 이용의 공간적 특성을 고려하여 지표수와 연계한 지하수 이용기반이 구축되어야 한다. 지표수 공급이 가능한 지역은 지표수를 우선 공급하거나 지하수와 혼합 또는 교차하여 공급하고 물공급 취약지역에서는 지하수 공급 기반시설을 구축하는 것이다. 세 번째 전략은 농업용 지하수 시설의 공공관리 강화 및 관리 효율화이다. 특히 지하수이용이 밀집한 지역에서는 지하수 인허가 기준을 강화하고 용도별 관리체계 구축이 필요하다. 밭용수 공급은 농가 소득과 밀접한 연관이 있기 때문에 물이용의 지속가능성과 함께 농가 소득증대를 고려하는 공편인적 관점에서의 관리가 필요할 것으로 생각된다.

This study empirically analyzed the relationship between founder competency and business performance based on the premise that founder competency is the main internal resource of a company from a resource-based view, using a sample of 2,196 startups less than five years old collected and evaluated by the Korea Technology Finance Corporation during the 2016 technology evaluation. The results showed that the technological, managerial, and financial competence of founders had a positive effect on the business performance of startups, and the characteristics of founders' academic major had a moderating effect on the relationship between founder competency and business performance. Based on these findings, this study contributes to the theoretical discussion that technological, managerial, and financial competencies of founders are factors that improve business performance, and provides practical and policy implications for effective entrepreneurship education by suggesting that entrepreneurship education should be transformed and strengthened, including cross-training of founders majoring in science and engineering to foster managerial and financial competencies.

This study analyzed the role of innovation intermediaries on the performance of technology-based firms in Korea. Technology-based firms are important to the economy because they contribute to regional economic development and national competitiveness. In Korea, various types of intermediaries, such as Techno-parks and incubators have been established to foster technology-based firms. Researchers analyzed various factors influencing the performance of technology-based firms. On the other hand, there have been few studies on the relationship between the innovation intermediaries and the performance of technology-based firms in Korea. This study identified the firms' capabilities, institutional and environmental factors in the light of the literature. A total of 2,313 technology-based firms in Techno-parks, business incubator of public institutes and universities were surveyed. Of these, 110 respondents were used for empirical analysis. OLS techniques were applied to analyze the data. The empirical results showed that the marketing competence, R&D capacity, which is a firms' innovation capacity, have a positive effect on the performance. The support of intermediaries positively affects the performance of technology-based firms. The economic aspects of regional innovation infrastructure, and cooperation with the customer has a positive effect on the performance of technology-based firms.

현재 시행 중인 부하관리 프로그램들은 거의 대부분 간접부하관리 방식에 의존하고 있으며, 이러한 간접부하관리 프로그램들은 요금혜택에 기반을 두고 있다. 직접부하관리가 우리나라에 도입된 것은 2001년 5월이며, 이러한 직접부하관리 프로그램은 간접부하관리 프로그램에 비하여 다음과 같은 다양한 장점을 가지고 있다. 1) 부하관리 자원의 이용 가능성(availability)이 간접부하관리에 비하여 상대적으로 높다는 것과, 2) 기존의 간접부하관리 프로그램에서의 성과계량, 즉, 부하관리 실시에 따른 피크 수요감소량을 명확하게 알 수 있으므로 전력회사가 장단기 수급계획을 수립하는데 보다 확실하게 이를 고려할 수 있다는 것과, 3) 부하차단의 주체가 전력회사가 되므로 간접부하관리 방식이 안고 있는 수용가 부하차단의 불확실성이 낮아지며, 4) 궁극적으로 비용효과가 간접부하관리보다 큰 유용한 자원이다. 본 논문에서는 이러한 직접부하제어자원의 개요와 전력시장 참여 현황 및 해외사례를 소개하고자 한다.
