In its change in ICT Ecosystem, electronic government changes to its wireless m-Gov from existing PC-based e-Gov. Thus, in order to realize the smart government, m-Gov needs to be vitalized and the strategies for this realization are required. Also, some countermeasures for those strategies and political instructions which the electric government should follows are needed. Above two are the ultimate purpose in pursuing administrative ideals because the realization of m-Gov innovates the government and betters quality of national life off. Therefore, this paper, to realize the smart government, provides some strategies for vitalization of m-Gov's electric government services, their countermeasures, and political instructions for Smart m-Gov.

As ICT Ecosystem does, electronic government changes in its form. Accordingly, in order to realize Smarter m-Gov, the governments need to vitalize m-Gov services and enact technology policy. Therefor, this manuscript suggests possible model of m-Gov realization and security algorithm as a technology policy which applies quantum cryptography system to server security for the construction of secured m-Gov's infrastructure. What the manuscript suggests seeks administrative ideas of Smarter m-Gov's services which contain security, stability, and economic feasibility for the benefits of nation and enterprises.

Mobile Government is one of the new and important developments in e-government. The promise of m-government to provide greater access to government information is progressing in many developed and developing countries. Current Mobile Government does not exploit the full potential of available technology. Research shows there is a lack of a perfect killer application [2][1]. Firstly, this paper begins with an overview of e-gov and m-gov. In this context, this paper aims to present a framework to find killer applications in M-government to which researchers must pay attention and develop suitable way to perform according to different countries' contexts.

Analysis of benthic macroinvertebrate community and biological estimation of water quality by the benthic macroinvertebrates were conducted at Olympic Park at its nearby waters in Seoul from December, 2004 to September, 2005. The benthic macrovertebrates were 49 species. Among them, 39 species of aquatic insects were included 11 species in odonata, 9 species in diptera, 7 species in hemiptera, 6 species in coleoptera, 3 species in ephemeroptera, 2 species in trichoptera and 1 species in lepipdoptera, and 10 species of non-insects were 6 species in mollusca, 2 species in hirudinea and 2 species in oligochaeta. Species number of lakes, Seongnae Stream within and outside the Olympic Park was 25 species, 35 species and 33 species, respectively. Individual number of lakes, Seongnae Stream within and outside the Olympic Park was $131\;inds/2.5m^2\;239\;inds/2.5m^2\;556\;inds/2.5m^2$, respectively. Mean dominance indices of lakes, Seongnae Stream within and outside the Olympic Park was 0.74, 0.61 and 0.72, respectively. According to the saprobic system based on the ESB index(Ecological score of benthic macroinvertebrate community), all survey sites are $\beta-mesosaprobic$ waters. To increase of abundance of benthic macroinvertebrates, regular interval monitoring has to be enforced and standard of water quality for the ecological ponds of Olympic Park has to be prepared.

최근 클라우드가 새로운 패러다임으로 등장하면서 클라우드 서비스가 급증하고 있으나 대부분 인프라 서비스 또는 소프트웨어 서비스로 플랫폼 서비스의 경우 상대적으로 서비스 제공 사례가 적다. 하지만 최근 플랫폼 서비스를 제공하는 사례가 증가하고 있으며 이는 새로운 플랫폼 종속성의 우려를 낳고 있다. 즉 플랫폼 서비스를 선택하여 어플리케이션 개발이 이루어지면 계속 같은 플랫폼 서비스를 사용해야만 하는 종속성이 생기는 것이다. 본 논문에서는 이러한 클라우드 플랫폼 서비스 종속성 문제를 해결하기 위해 개방형 클라우드 플랫폼 서비스의 필요성과 함께 표준프레임워크를 기반으로 개방형 클라우드 플랫폼 서비스를 구현할 수 있는 방안을 제시하고자 한다.

This study examines how individual attitudes towards government and society are affected by political conservatism and liberalism. With survey data from 533 adults(M=249, F=284) who live in Seoul and surrounding areas, we examine the general attitudes towards society, expectation on general government and differences in attitudes towards the Roh Moo-hyun Gov't and the Lee Myung-bak Gov't between liberals and conservatives. Results show that liberals and conservatives vary by age and residence, whereas attitudes towards the general government and society are not. By contrast, liberals and conservatives are distinctly different evaluating governments with specific political tendency. Liberals are more positive to the Roh Moo-hyun Gov't than conservatives whereas the evaluation appears conversely on the Lee Myung-bak Gov't. These differences of attitudes are more distinctive when dividing liberals and conservatives by subjective judgement and political party preference than conceptual measurement of political ideology. These findings suggest that political conservatism and liberalism is the factor that has powerfully affected individual attitudes in the specific political context rather than a consistent ideological framework in Korean society.

This study was carried out to investigate total suspended particulates (TSP) in Iksan area collected by nine stages Anderson air sampler and High volume air sampler from Jul. 1996 to Jul. 1998.The results are as follows1. The average of TSP concentration to be collected by Anderson air sampler and High volume air sampler in Iksan city are $59{\mu}g/m^3$, $67{\mu}g/m^3$. It was below the level of environmental standard. 2. The average of TSP concentration by measured method are HVAS > AS > Gov. 3. The average of TSP concentration on seasonal change are higher spring than winter. It were $65.5{\mu}g/m^3$ of Spring, $57{\mu}g/m^3$ of Summer, $52.5{\mu}g/m^3$ of Fall, $61{\mu}g/m^3$ of Winter. 4. Particle size 3istribution of atmospheric particulate was divided into two groups, coarse group was made by particles larger than $1.1-2.1{\mu}m$ in diameter and fine groups smaller than $1.1-2.1{\mu}m$ in diameter. about 50% of total suspended particle measured by Anderson air sampler during the sampling period was coarse particle.

Seismic and wind load performances of buildings are commonly improved by using bracing systems. In practice, standard bracing systems, such as X, Y, V, and K types are used. To determine the appropriate bracing type, the designer uses trial & error method among the standard bracings to obtain better results. However, using topology optimization yields more efficient bracing systems or new bracing can be developed depending on building and loading types. Determination of optimum bracing type for minimum deformation on a building under the effect of wind load is given in this study. A new bracing system is developed by using topology optimization. Element removal method is used to determine and remove the comparatively inefficient materials. Optimized bracing is compared with proposed bracing types available in the related literature. Maximum deformation value of building is used as performance indicator to compare effectiveness of different bracings to resist wind loads. The proposed bracing, yielded 99%, deformation reduction compared to the unbraced building.

2012년 고시된 '정보시스템 구축 운영 지침'에 따라 행정안전부에서는 '전자정부 SW 개발 운영자를 위한 시큐어 코딩 가이드'를 배포하고 있다. 시큐어 코딩 기법을 예제 위주로 제시함으로써, 개발 실무에 활용도를 높이기 위하여 배포된 시큐어 코딩 가이드는 유용한 지침서임에는 틀림이 없으나, 개발자 개개인이 그 내용을 모두 숙지하기 위해서는 많은 시간과 노력을 필요로 한다. 특히 입력 데이터 검증 및 표현에 관한 시큐어 코딩은 시스템 아키텍쳐 차원의 중앙집중적인 관점이 아닌 개발자 개개인이 구현한 기능 단위 수준에서 수행되고 있는 필드의 현실상, 이를 중앙집중적인 관점에서의 입력 데이터 검증을 통하여, 보다 안전한 소프트웨어를 제작하기 위한 방법을 코드 중심의 사례로 설명하고자 한다.

기후변화 및 토지이용변화에 따라 강우량 및 증발산량 등과 같은 물순환계 구성요소가 변화하면 유역에서의 물순환계가 영향을 받게 된다. 이렇게 변화된 유역의 물순환계를 종합적으로 관리하기 위해서는 물순환 개선 기술을 통한 지속가능하고 건전한 물순환체계의 구축이 필요하다. 유역 물순환 개선 기술은 기후변화가 진행 중에 있거나 예상되는 지역에 대하여 강우-유출수를 지연, 저류, 침투시켜 지속가능한 물순환체계를 유지 회복하도록 하는 기술이라 할 수 있다. 한국건설기술연구원에서는 기후변화 대비 수자원 적응기술 개발 연구단(CCAW, Climate Change Adaptation for Water resources)의 연구비 지원을 받아 유역 건전성 및 취약성을 평가 하고 취약한 유역에 대한 물순환 개선기술을 확보하기 위한 연구를 수행 중에 있다. 특히, 수년간 국가연구개발사업을 통해 개발되고 사업화에 성공한바 있는 유역 물순환 평가 모형인 CAT(Catchment hydrologic cycle Assessment Tool)을 수정 개선하여 수요자 중심의 활발한 현장 적용을 도모하고 있다. 본 연구에서는 개발된 유역 물순환 개선 및 평가시스템의 적용성 평가를 위하여 대상유역으로 태국의 Lam Takhong 저수지 유역을 선정하였다. Lam Takhong 저수지 유역은 유역면적은 $1,423km^2$이며 저류량은 약 $440{\times}106m^3$이다. 입력자료인 DEM, Land Cover 자료는 USGS Hydro1K (https://earthexplorer.usgs.gov/), 하천망 및 유역경계 자료는 USGS HydroSHEDS (https://hydrosheds.cr.usgs.gov/dataavail.php), 기상 및 관측 유입량, 저수지 제원 등의 자료는 APEC 기후센터의 협조를 받아 1976년부터 2016년까지의 일단위 자료를 이용하였다. 모의결과는 저수지 월별 관측 유입량과 상류 유역의 모의 유출량을 이용하여 비교-분석 하였다. Lam Takhong 저수지 상류 유역은 APEC 기후센터에서 SWAT 모형을 이용하여 저수지 유입량 분석을 수행한 바 있다. 따라서 본 연구의 결과를 SWAT 모의결과와 비교하여 그 적용성을 검증하였다. 월별 관측 유입량과 저수지 상류 유역 모의 유출량을 비교한 결과 CAT의 경우 결정계수(R2) 값이 0.86, SWAT은 0.76으로 나타나 CAT의 적용 결과가 좀 더 우수한 것으로 나타났다. 모의 결과는 매개변수 최적화 과정을 거치지 않은 결과이며 SWAT 모형과의 결과 비교를 위하여 매개변수는 동일하게 적용하였다. 향후 매개변수 최적화 모듈을 통해 검 보정 단계를 거친다면 정밀한 분석이 가능할 것으로 판단된다.
