정보화에 대한 꾸준한 정책적 지원과 투자를 통하여 우리나라의 전자정부는 세계 6위 수준으로 평가되는 등 괄목할 성과를 이루었으나, 각 부처별로 정보시스템을 구축 운영함으로써 중복투자 및 정보자원 공동 활용 미흡 등의 문제가 발생되고 있다. 따라서 전자정부 시스템 정보자원에 대한 통합적 관리노력을 추진 중이나, 현재 시스템 아키텍처에 대한 서술 방식이 상이하여 이해관계자간의 의사소통을 저해하는 요인으로 작용하고 있다. 이에 따라 공동활용 가능한 정보자원을 명확히 식별할 수 있는 시스템 아키텍처의 표준적인 서술(standardized architecture description) 방안 수립이 절실히 요구된다. 본 연구에서는 전자정부 시스템 아키텍처의 표준적 서술 기반을 제공하는 기능-네트워크 매트릭스 모형(function-network matrix model)을 제안하였다. 기능-네트워크 매트릭스는 기능계층 구분을 열로, 네트워크 영역 구분을 행으로 나타내어, 기능계층과 네트워크 영역을 통합하여 표현할 수 있는 모형이다. 기능-네트워크 매트릭스를 활용하여 전자정부 민원행정시스템 및 행정업무시스템을 대상으로 적용한 사례를 제시하였다. 이를 통하여 서로 다른 시스템간의 아키텍처의 공통점과 차이점을 명확히 파악하고, 시스템간 정보자원의 공동활용 및 시스템 통합을 위한 정보자원 식별의 가능성을 확인하였다.

본 연구에서는 공공도서관의 이용을 통한 정보의 공유가 각 개인의 사회자본을 형성하고 강화하는데 어떠한 영향을 미치는지를 실증적으로 분석하였다. 공공도서관 이용자를 대상으로 한 설문조사를 통해 분석한 결과, 공공도서관의 이용 빈도가 높고 공공도서관 프로그램에의 참여가 높을수록 정보공유에 대한 인식도와 공유된 정보에 대한 신뢰도가 높게 나타났다. 또한 사람들 사이의 정보공유는 공공도서관 이용을 매개로 했을 때 보다 활발하게 이루어지고 있으며, 이는 각 개인의 구조적, 관계적 사회자본에 전반적으로 긍정적인 영향을 미치는 것으로 분석되었다. 반면, 공공도서관의 이용을 통한 정보공유가 인지적 사회자본의 형성에는 상대적으로 큰 역할을 수행하지는 못하는 것으로 나타나, 공공도서관의 이용 및 정보의 공유가 개인적인 정보요구를 충족시키는데 집중되는 것으로 분석되었다.

The actual quality of the concrete in the structure for Irrigation may differ from that represented by the cylinders because the age, consolidation, or curing of the in-place material may not be well represented by the standard test specimens. The objective of this paper is to offer a base data of specification is the best fit the ready-mixed concrete strength to the specified, and to address this deficiency, so that the strength information of the concrete in the structure for Irrigation can be rationally accounted for in the assessment of the quality condition of this. The strength of concrete in the hydraulic structures is checked using strength of core obtained from that, and 28-day-old cylinder strength is analyzed using cylinder data of the ready-mixed concrete.

Larger area will be constructed in a harbor land and container terminal which are constructed in reclaimed land using the dredged materials. Soil improvement work is to be carried out including constructibility, in which is monitoring devices, measuring frequency, installations etc. The ground water tables in the reclaimed area are affected by the several factors which are design reclamation level, consolidation settlement, remaining surcharge pressure and remaining excess pore water pressure. The plan wii be drawn up in which monitoring results for the ground water tables are capable to provide the reliable ground water table when designers and civil engineers construct the harbor structures considering constructibility.

Ni(Fe)Al powders containing a homogeneous distribution of the in-situ formed AIN and $Al_2O_3$ dispersoids have been produced by mechanical alloying process in a controlled atmosphere using high energy attrition mill. The powders have been successfully consolidated by hot extrusion process. The phase information investigated by TEM and XRD analysis reveals that Fe can be soluble up to 20% to the NiAl phase ($\beta$) at room temperature after MA process. Subsequent thermomechanical treatment under specific condition has been tried to induce secondary recrystallization (SRx) to improve high temperature properties, however, the clear evidence of SRx was not obtained in this material. Mechanical properties in term of strength at room temperature as well as at high temperatures have been improved by the addition pf AIN, and the room temperature ductility has been shown to be improved after heat treatment, presumably due to the precipitation of second phase of $\alpha$ in this material.

Elastic and electromagnetic waves can be used to gather important information about particulate materials. To facilitate smart geophysical characterization of particulate materials, their fundamental properties are discussed and experimental procedures are presented for both elastic and electromagnetic waves. The first application is related to the characterization of particulate materials using shear waves, concentrating on changes in effective stress during consolidation, multi-phase phenomena with relation to capillarity, and microscale characteristics of particles. The second application involves electromagnetic waves, focusing on stratigraphy detection in layered soils, estimation of void ratio and its spatial distribution, and conduction in unsaturated soils. Experimental results suggest that shear waves allow studying particle contact phenomena and the evolution of interparticle forces, while electromagnetic waves give insight into the characteristics of the fluid phase and its spatial distribution.

Improvement of soft clay deposit by preloading with vertical drains is one of the most popular techniques followed worldwide. These drains accelerate the rate of consolidation by shortening the drainage path. Although the analytical and numerical solutions available are mostly based on equal strain hypothesis, the adoption of free strain analysis is more realistic because of the flexible nature of the imposed surcharge loading, especially for the embankment loading used for transport infrastructure. In this paper, a numerical model has been developed based on free strain hypothesis for understanding the behaviour of soft ground improvement by vertical drain with preloading. The unit cell analogy is used and the effect of smear has been incorporated. The model has been validated by comparing with available field test results and thereafter, a hypothetical case study is done using the available field data for soft clay deposit existing in the eastern part of Australia and important conclusions are drawn therefrom.

Company A should maintain myriad conversion tools for the purpose of making a geometric compilation of navigation maps. Company A is already using complex compilation tools, which are tailored to geographical areas and various GPS models. However, due to frequent requirement and personnel changes, there is an endless challenge for perfect tool configuration and multiple map consolidation. To solve this problem, Company A launched a process automation project using Graphviz, which is an open source workflow graph visualization software. Before implementation, they had to document their current map compilation processes and then match it with the applicable conversion tool. For effective representation of process controls, a new graphical process notation is designed, i.e. Y Block diagram. The authors will compare Y Block diagram with other process notations and explain why Y Block diagram is more useful for tool based business processes such as digital map generation processes.

How to conceive fraternity in difference? I will hold two premises to answer this question. First: fraternity is an ineradicable element of the Political. Second: the recognition of fraternity in difference is a precondition for the consolidation of fraternal relations in Latin America in the context of coloniality. On the same path, I will show that fraternity must be thought of as difference in order to face the logic of neoliberal life imposed by capitalism in globalization. The articulation of both premises in the political praxis would contribute to the preservation of our life in common; in conditions of dignified existence. The fraters of precariousness and vulnerability are the ones who can re-establish being-with- and being-together.
