In the past, the Ministry of Agriculture, Food, and Rural Affairs (MAFRA) conducted research into and production of agricultural statistics. As a result of organizational changes, these responsibilities were transferred to Statistics Korea in 1998 and 2008. So, the MAFRA managed data without a formal system for managing data and statistical information. The demand for a foundation to improve the usefulness of agri-food statistics has recently increased due to the necessity for basic data representing the realities of rural and agricultural areas. This is especially true for field-oriented agricultural administration. This study aims to propose a strategy for the systematically integrated administration of dispersed data and statistical information. It served as the foundation for the integrated management of distributed administrative and statistical data.

Cloud computing is a currently developing revolution in information technology that is disturbing the way that individuals and corporate entities operate while enabling new distributed services that have not existed before. At the foundation of cloud computing is the broader concept of converged infrastructure and shared services. Security is often said to be a major concern of users considering migration to cloud computing. This article examines some of these security concerns and surveys recent research efforts in cryptography to provide new technical mechanisms suitable for the new scenarios of cloud computing. We consider techniques such as homomorphic encryption, searchable encryption, proofs of storage, and proofs of location. These techniques allow cloud computing users to benefit from cloud server processing capabilities while keeping their data encrypted; and to check independently the integrity and location of their data. Overall we are interested in how users may be able to maintain and verify their own security without having to rely on the trust of the cloud provider.

Quantity discounts provide a practical foundation for supply chain inventory policies, improving the supplier's profit and reducing the buyer's inventory cost simultaneously. Traditional quantity-discount research, which deals with inventory coordination between a buyer and a supplier, is extended to a stationary stochastic environment. This research shows that the magnitude of the optimal discounts scheduled by the deterministic quantity discount models may not be large enough to cover the buyer's additional inventory stocking risks under uncertain conditions. As a result, the buyer's total inventory cost may often increase rather than decrease. In contrast, the proposed model allows the supplier to identify the discount level, which shares the buyer's amplified risk associated with temporary overstocking and ensures that both buyer and supplier benefit economically. The performance of the proposed model was tested in the continuous review environments via numerical experiments. The experimental results support the proposed method as a feasible alternative in coordinating inventory decisions under stochastic demand.

There are insufficient models that find problems and solutions for accident prevention through risk assessment and suggest safe work process and work instruction from foundation works to finish work for accident decrease. This paper presents a quantitative risk assessment model by analysis of risk factors in each process such as appurtenant works, temporary works, structural works, equipment work, finishing work and etc based on accident examples and investigation on actual condition in plants construction work. In addition, the safety management system was developed to perform risk assessment of plants construction and use it for effective safety training for labor.

This study concerns performance evaluation of the research-funding agencies focused on Korea Science and Engineering Foundation(KOSEF). On the basis of the constituents approach and the systems approach of organizational effectiveness theory, the evaluation items are derived reflecting generic characteristics of the research-funding agencies, and their priorities are determined using analytic hierarchy process(AHP). Three groups of constituents with differing interest and expections are identified, and their perceptions on the importance of the evaluation items are measured through questionnaire survey. Analyses show that the evaluation items perceived important by each constituency are significant different from one another. The implications of the result to the Government and KOSEF are discussed.

최근 스마트폰의 보급 및 웹 서비스의 도입으로 온라인 사용자들은 대규모의 콘텐츠를 시간과 장소에 관계없이 접할 수 있게 되었다. 그러나 사용자들은 대규모의 콘텐츠 사이에서 원하는 콘텐츠를 찾는 데 어려움을 겪게 되었다. 이러한 문제를 해결하기 위해 다양한 분야에서 사용자 모델링 및 추천 시스템에 대한 연구가 활발하게 수행되었다. 그러나 정보 환경의 변화에 따른 시니어 계층의 적극적인 변화에도 불구하고 시니어 계층에 초점을 맞춘 사용자 모델링 및 추천 시스템에 대한 연구는 매우 부족한 실정이다. 이에 본 논문에서는 기계 학습 방법을 기반으로 스마트 시니어 계층의 선호도를 파악할 수 있는 모델링 방법을 제안하고, 스마트 시니어 분류 모델을 개발한다. 이 결과, 스마트 시니어 계층의 선호도를 파악할 수 있을 뿐만 아니라 스마트 시니어 분류 모델 개발을 통해 시니어 사용자에게 가장 적합한 활동 및 콘텐츠를 제공하는 콘텐츠 추천 연구에 대한 발판을 마련하였다.

This paper introduces a new method to study the hydroelastic behavior of hinged Very Large Floating Structures (VLFSs). A hinged two-module structure is used to confirm the present approach. For each module, the hydroelasticity theory proposed by Lu et al. (2016) is adopted to consider the coupled effects of wave dynamics and structural deformation. The continuous condition at the connection position between two adjacent modules is also satisfied. Then the hydroelastic motion equation can be established and numerically solved to obtain the vertical displacement, force and bending moment of the hinged structure. The results calculated by the present new method are compared with those obtained using three-dimensional hydroelasticity theory (Fu et al., 2007), which shows rather good agreement.

The Zika virus, which is a member of the flavivirus genus, poses a serious threat to humanity because there is no vaccine or cure. Zika is suspected to cause microcephaly, and it is rapidly spreading throughout parts of Brazil. Surprisingly, there are no known protein structures for the virus which are essential for drug and vaccine development. This paper investigates the Zika virus's nonstructural proteins with template-based modeling by using GalaxyTBM/Refine/SC. GalaxyDock was used to examine the effectiveness of various known serine protease inhibitors in inhibiting the Zika viral protease. In testing five inhibitors, Kunitz soybean trypsin inhibitor showed the strongest binding affinity (-10.082 kcal/mol). This paper provides a rudimentary foundation for further drug discovery research regarding the Zika virus.
