Progressing of Web2.0 and social digitalization are lead to changing citizens participation and citizen centric service of civic service. To meet this trends that is online collaboration and sharing, citizen's service that provides our government, also need to changing web2.0 style. This paper argues that government could now grasp the opportunities that are emerging in terms of web2.0 Current policy and action is not yet adequate to grasp these opportunities. So this study focused on strategies of civil services based on web2.0 using NCIA(National Computerization Integrated Agency) cases. For the purpose, we analyze former researches related with civil service. And then, we propose web2.0 adaptation strategies for NCIA.

It has been used that fluorinated compounds could be applied to cosmetic products. It is that fluorinated conpounds are hydrophobicity and lipophobicity. These fluorinated compounds are reported to form a highly protective and effective film against most aggressive chemical and physical agents. PerfluropolymethyoisopropylEther has homophobicity and are colorless, odorless, tasteless and non-greasy. In this we made a success to formulate the new type of hand care cream using PFPE. PFPE are suitable thickness and chemical inertness to skin. The reason that we select PFPE for this investigation. We developed the new type hand care cream by adsorption and dispersion of PFPE. There are very stable dispersion and highly moisture diffusion control. And these characteristics were verified by actual consumer test.

Human lymphotoxin (LT) was produced in E. coli as a soluble protein. The level of recombinant human LT production was about 4% of the total souble proteins of E. coli extracts. Recominant human LT was purified to apparant homogeneity by a simple procedure utilizing FPLC on Mono Q and Mono S columns. The specific activity of the purified LT was $10\times10^7\;units/mg$.

Artificial intelligence, especially deep learning technology, is penetrating the majority of research areas, including the field of bioinformatics. However, deep learning has some limitations, such as the complexity of parameter tuning, architecture design, and so forth. In this study, we analyze these issues and challenges in regards to its applications in bioinformatics, particularly genomic analysis and medical image analytics, and give the corresponding approaches and solutions. Although these solutions are mostly rule of thumb, they can effectively handle the issues connected to training learning machines. As such, we explore the tendency of deep learning technology by examining several directions, such as automation, scalability, individuality, mobility, integration, and intelligence warehousing.

Pushbroom 방식의 CCD 영상에서 발생하는 pixel들 사이의 Non-uniformity 원인은 CCD pixel 면적의 차이, Dark current 영향, Output amplifier 차이, input radiance의 차이 등과 같은 CCD의 특성에 의해 발생하게 되며, CCD의 특성에 의해 발생되는 pixel사이의 상대복사량 차이인 Non-uniformity errors은 위성영상에서 줄무늬의 일차적 원인이 된다. 이러한 CCD의 상대복사보정을 위해서는 일차적으로 CCD의 특성을 잘 파악할 수 있는 지상에서 보정 값이 계산되어져야 하며 위성발사 후 보정 값이 다시 update 되어야 한다. 본 연구에서는 다목적실용위성2호의 상대복사보정을 위한 준비로서, 지상에서 만들어진 MSC CCD PAN1 영상과 Pushbroom 방식의 다목적실용위성1호 영상을 시험자료로 이용하여 pixel 사이의 줄무늬를 제거하기 위한 상대복사보정을 수행하였다.

Concrete structures often present volumetrical changes particularly due to thermal and moisture related shrinkages. Volumetric instability is detrimental to the performance and durability of concrete structures because structural elements are usually restrained. These restrained shrinkages develope tensile stresses which often results in cracking in combination with the low fracture resistance of concrete. Early-age defects in high-performance concrete due to thermal and autogenous deformation shorten the life cycle of concrete structures. Thus, it is necessary to examine the behavior .of early-age concrete at the stages of design and construction. The purpose of this study was to propose a shrinkage models of VES-LMC (very-early strength latex-modified concrete) at early-age considering thermal deformation and autogenous shrinkage.

Future wireless network aims to integrate different radio access networks (RANs) to provide a seamless access and service continuity. In this paper, a new resource denotation method is proposed in the WLAN and LTE heterogeneous networks based on a concept of spectral bandwidth mapping. This method simplifies the denotation of system resources and makes it possible to calculate system residual capacity, upon which an economic model-based network selection algorithm is designed in both under-loaded and over-loaded scenarios in the heterogeneous networks. The simulation results show that this algorithm achieves better performance than the utility function-based access selection (UFAS) method proposed in [12] in increasing system capacity and system revenue, achieving load balancing and reducing the new call blocking probability in the heterogeneous networks.

Previous studies have addressed the management of phyllosphere pathogens by leaf and root-associated microbes. The present study evaluated the effect of the foliar application of three strains of Bacillus spp. on plant growth and fruit quality. The application of a bacilli spore preparation significantly improved leaf growth parameters such as leaf thickness and photosynthesis capacity, indicating that bacilli treatment directly promoted leaf growth. In addition, foliar treatment resulted in an improvement in the key indicators of fruit quality including water, glucose, and sucrose contents. The present results suggest that foliar spraying of beneficial bacilli is a potential treatment of wide application for the improvement of apple quality. Foliar application of bacilli preparation as effective plant growth-promoting rhizobacteria broadens the spectrum of their availability for orchard application.

Conditioning은 CMP(Chemical Mechanical Planarization)에 필수적인 공정중의 하나이다. Conditioning의 목적은 removal rate와 uniformity를 CMP 공정 중에서 일정하게 유지시키는데 목적이 있다. 예전의 conditioning disks는 stainless steel substrate 위에 diamond 입자를 올리고 Ni전기도금을 결합시켜서 사용하였다. 그러나, CMP 공정 중에 Ni의분해로 인한 금속의 오염과 diamond abrasive의 분리로 인하여 scratch 문제가 발생하였다. 이 문제를 해결하기 위해서 ceramic substrate와 그것을 정밀 가공하는 기술을 응용함으로써 본래의 conditioning disks가 가지고 있는 diamond 입자의 분리와 metals 분해의 문제를 해결할 수 있게 되었다.
