Our society is depending on mobile devices that play a major role in our lives. Utilizing these devices is possible due to their speed power and efficiency in performing basic as well as sophisticated operations that can be found in traditional computers like desktop workstations. The challenge with using mobile devices is that organizations are concerned with the interference between personal and corporate use due to Bring Your Own Device (BYOD) trend. This paper highlights the importance of mobile devices in our daily tasks and the associated risks involved with using these devices. Several technologies and countermeasures are reviewed in this paper to secure the mobile devices from different attempts of attacks. It is important to mention that this paper focuses on technical measures rather than considering different aspects of security measures as recommended by the cybersecurity community.

The increased investment in technological innovations makes the investigation of factors affecting technology adoption more interesting. Several perspectives have been proposed to explain the determinants of information technology adoption. While the traditional innovation diffusion research streams try to explain and predict adoption behavior with the adopter's perceptions about the characteristics of the innovation itself, critical mass theorists argue that adoption behavior as a collective action is based on what their business partners are doing and whether there exists enough critical mass to justify the investment. Drawing on theses two perspectives, this study investigates the decision criteria in the adoption of information technology as innovation and factors affecting the decision criteria. The survey results reveal that the adoption behavior is affected both by innovation characteristics and by critical mass's activity. Correlation analysis, t-test, and stepwise regression models also show that as the environmental uncertainty is getting higher, adoption decision is affected more by what others are doing, and that highly competitive organizations seem to play the role of critical mass.

Engineering graph plays an important role in design and manufacture, such as architecture, machinery, manufacture, military. However, almost no persons consider the security and copyright of two-dimensional engineering graph. A novel method for two-dimensional engineering graph watermark based U system is proposed in this paper. Watermarks generated by this technique can be successfully extracted even after rotation, translation and scaling transform.

급격한 정보기술, 저작도구의 발전 및 새로운 형태의 자료에 대한 요구 등은 정보전문직인 사서의 업무와 역할에 있어서 새로운 전환점을 제공하고 있다. 전통적으로 도서관은 인쇄형태의 정보를 주로 처리하고 관리하였으나 도서관에 대한 새로운 요구와 정보형식의 변화는 새로운 형식의 정보에 대한 유통과 관리 및 이용을 위한 전자도서관을 출현하게 하였으며 이러한 전자도서관의 출현은 정보처리의 새로운 방향성을 제시하여 주고 있으며 다량의 정보 속에서 이용자에게 적절한 정보를 신속하고 정확하게 제공하는 역할을 수행하는 정보전문직에 대한 새로운 요구를 가져오고 있다. 이렇게 정보와 관련된 정보기술의 발전과 사회적인 새로운 요구들은 이들 정보의 처리와 유통을 담당하고 있는 정보전문가, 즉 사서를 양성하는 문헌정보학분야에 새로운 도전의 영역을 제공하는 한편 문헌정보학의 전통적인 영역을 침범 당할 수 있는 양면성을 보여 주고 있다. 이러한 사회적인 흐름과 함께, 정보전문직으로서 문헌정보학전공자들은 자신들의 위치와 역할을 수행하기 위하여 다양한 노력을 기울이고 있으며 현재에도 많은 정보관련 분야에서 활발한 활동을 벌이고 있다. 본 글에서는 현재 문헌정보학전공자들이 전통적인 영역인 도서관이 아닌 새로운 분야에서 활동하고 있는 현황, 역할 및 지위에 대하여 알아보았으며 이를 통하여 정보전문직으로 확고히 자리매김을 하기 위하여 요구되는 자질에 대하여 알아보았다.

We have performed silicon-to-silicon anodic bonding using glass layer deposited by electron beam evaporation. Wafers can be bonded at $135^{\circ}C$ with an applied voltage of $35V_{DC}$, which enables application of this technique to the vacuum packaging of microelectronic devices, because its bonding temperature and voltage are low. From the experimental results, we have found that the evaporated glass layer more than $1\;{\mu}$ m thick was suitable for anodic bonding. The role of sodium ions for anodic bonding was also investigated by theoretical bonding mechanism and experimental inspection.

Cyber security plays an important role in the field of IT industry and other industry too. Whenever we talk about cyber security, the word cybercrime pops out. Cybercrime is the biggest issues we are facing right now. Every 39 seconds an attacker is hacking something. Since 2008 to 2019 there are more than 8800 data breach cases is being found or filed. Even as we are aware of cybercrime and its stats, only 5% organization are fully secured and other 95% are not fully secured. According to survey 56% organization have weak controls. Basically they are not secured. Apart from taking measures cyber security are facing huge challenges or disturbs to many. This paper mainly focuses on dare to cyber security and also center of attraction is cyber security expertise, morals with changing in technology with time. [1]

In this article, a new Aloha-based tag identification protocol is presented to improve the reading efficiency of the EPC C1 Gen2-based UHF RFID system. Collision detection (CD) plays a vital role in tag identification process which determines the efficiency of anti-collision protocols since most Aloha-based protocols optimize the incoming frame length based on the collisions in current frame. Existing CD methods are ineffective in identifying collision, resulting in a degradation of identification performance. Our proposed algorithm adopts an enhanced CD (ECD) scheme based on the EPC C1 Gen2 standard to optimize identification performance. The ECD method can realize timely and effective CD by detecting the pulse width of the randomly sent by tags. According to the ECD, the reader detects the slot distribution and predicts tag cardinality in every collision slot. The tags involved in each collision slot are identified by independently assigned sub-frames. A large number of numerical results show that the proposed solution is superior to other existing anti-collision protocols in various performance evaluation metrics.

The trend of the microjoining technology by the laser-soldering process has been reviewed. Among the production technologies, joining technology plays an important role in the fabrication of electronic components. This has led to an increasing attention towards the use of modern microjoining technology such as micro-resistance spot joining, micro-soldering, micro-friction stir joining and laser-soldering, etc. This review covers the recent technical trends of laser-soldering collected from the COMPENDEX DB analysis of published papers, research subject and research institutes.

Documents contain information that can be used for various applications, such as question answering (QA) system, information retrieval (IR) system, and recommendation system. To use the information, it is necessary to develop a method of extracting such information from the documents written in a form of natural language. There are several kinds of the information (e.g., temporal information, spatial information, semantic role information), where different kinds of information will be extracted with different methods. In this paper, the existing studies about the methods of extracting the temporal information are reported and several related issues are discussed. The issues are about the task boundary of the temporal information extraction, the history of the annotation languages and shared tasks, the research issues, the applications using the temporal information, and evaluation metrics. Although the history of the tasks of temporal information extraction is not long, there have been many studies that tried various methods. This paper gives which approach is known to be the better way of extracting a particular part of the temporal information, and also provides a future research direction.
