Since smartphones are utilized in the ranges from personal usages to governmental data exchanges, known but not patched vulnerabilities in smartphone operating systems are considered as major threats to the public. To minimize potential security breaches on smartphones, it is necessary to estimate possible security threats. So far, there have been numerous studies conducted to evaluate the security risks caused by mobile devices qualitatively, but there are few quantitative manners. For a large scale risk evaluation, a qualitative assessment is a never ending task. In this paper, we try to calculate relative risk levels triggered by software vulnerabilities from unsecured smartphone operating systems (Android and iOS) among 51 Asian countries. The proposed method combines widely accepted risk representation in both theory and industrial fields. When policy makers need to make a strategic decision on mobile security related agendas, they might find the presented approach useful.

Objectives : In pediatrics, one of the most difficult thing might be medication because infant or child cannot take medicine easily. In traditional medicine, Korean taffy or paste preparations sometimes prescribed. Xiao'eryaozhengzhijue was published by Qianyi in 1119 and is specialized for pediatrics text. So I tried to research paste preparations in Xiao'eryaozhengzhijue. Methods : I derived paste preparations from Xiao'eryaozhengzhijue ; paste preparations named on it, and used as paste preparations etc. Results : 1. There were external and internal application of paste preparations. 2. Diverse secondary materials were used for making paste preparations. 3. Several chief complains were recorded in Xiao'eryaozhengzhijue. Conclusions : Paste preparations are really useful way to disease of pediatrics because infant or child cannot take his or her medicine easily. Through the research, I could find out the facts that there are diverse shapes of paste preparations and usages of paste preparations in Xiao'eryaozhengzhijue.

The characteristics of titanium alloy as a relatively advanced material is low density, avirulent and, superior corrosive resistant, therefore the use of titanium alloy is increasing lately in aerospace and mechanical technologies, precision machinery, electronics industry, petro-chemical industries and biomedical areas. In these days, the titanium alloy product is required various surface qualities of not only smooth surface but also rough surface depending on usages. The purpose of this experimental research is to find the optimum surface roughness of titanium alloy of Ti-6Al-4V, by micro abrasive blasting as depending variable conditions of working pressure, nozzle size, working time, stand of distance and power particle size.

최근 정보 기술의 가장 큰 변화 중 하나인 스마트폰은 다양한 정보 및 서비스를 손쉽게 제공하므로 기업의 여러 분야에 활용될 수 있다. 특히 의사결정을 위해 구축된 방대한 데이터를 검색하는 시스템의 경우에 스마트폰으로 서버에 질의를 요청하여 결과를 제공받을 수 있다. 스마트폰의 경우 4G 방식을 사용하여 빠른 속도로 통신할 수 있으나 배터리 소모가 매우 심하다는 것이 큰 단점이다. 본 논문에서는 모바일기기인 클라이언트와 서버로 구성된 모바일환경에서 배터리의 소모를 줄이기 위해 모바일 뷰를 제안한다. 모바일 뷰는 질의처리 시 실체화 뷰를 이용하여 서버와의 통신을 줄임으로써 배터리 소모를 줄인다. 또한 소스 변경에 따라 모바일 뷰의 일관성을 제어하기 위한 방법을 분류하고 제시된 배터리소모 비용 모델을 기반으로 각 방법의 비용을 제시한다.

Although installations and usages of gang-form that has advantages of preventing fall disaster, the serious disasters from gang-form occur every year. This research focused on the continuous prevention of disasters in construction of outer wall of apartment working site through step by step safety management worker's checking table. The result is the worker's checking table for safety management in apartment gang-form works, through safety guidelines case studies, interviews with safety management experts and then extracting a check list.

Epidermal growth factor(EGF) known as a urgastrone is a powerful mitogen with a wide variety of possibilities for medical usages. A mature EGF coding region was isolated from human prepro-EGF sequence by a conventional PCR and cloned into pQE vector in which the gene product was supposed to be expressed with 6$\times$His tag for the subsequent purification. The recombinant mature EGF was expressed in M15[Rep4], an Escherichia coli host strain, in amount of 30-40% of total proteins pressent in E. coli extract by the addition of isopropylthio-$\beta$-galactopyranoside (IPTG). The recombinant EGF purified using a Ni2+-NTA affinity colume chromatography was active in its ability to induce phosphorylation on tyrosine residues of several substrate proteins when murine NH3T3 and human MRC-5 fibroblast cells were stimulated with it. This work may provide the basic technology and information for the production of recombinant EGF.

Zoogloea ramigera 115 was cultured for biopolymer production and its bioflocculant usages. Cultural conditions of the organism were examined with regard to high production of the microbial polysaccharide. The most suitable medium was found to contain glucose as a carbon source, $NaNO_3$ as a nitrogen source, and yeast extract as an organic nutrient. The initial pH of 6.0 proved to optimal. The biopolymer was extracted effectively using ultrasonication and high speed centrifugation, followed by propanol addition. Jar test results indicate that the polysaccharide produced by the organism is an effective flocculant.

This paper presents the constituent-based approach for aligning bilingual multiword expressions, such as noun phrases, by considering the relationship not only between source expressions and their target translation equivalents but also between the expressions and constituents of the target equivalents. We only considered the compositional preferences of multiword expressions and not their idiomatic usages because our multiword identification method focuses on their collocational or compositional preferences. In our experimental results, the constituent-based approach showed much better performances than the general method for extracting bilingual multiword expressions. For our future work, we will examine the scoring method of the constituent-based approach in regards to having the best performance. Moreover, we will extend target entries in the evaluation dictionaries by considering their synonyms.
