텍스트를 기반으로 하는 패스워드는 다방면에서 가장 많이 사용되고 있는 인증 수단이다. 하지만 이러한 패스워드는 사용자의 기억에 의존하기 때문에 사람들은 일반적으로 기억하기 쉽게 '!iloveY0u'와 같은 암호를 사용한다. 이로 인해 사용자들의 패스워드 간에 규칙성이 생기게 되어 HashCat과 같은 크래킹 도구에 의해 해킹될 수 있다. 딥러닝을 통한 패스워드 예측의 경우, 일반적인 패스워드 크래킹 도구와 달리 패스워드 구조 및 속성에 대한 사전 지식 및 전문적 지식 없이도 패턴을 추출하고 학습할 수 있어 활발히 연구되고 있다. 본 논문에서는 딥러닝 모델 중에서도 순환 신경망을 사용하여 텍스트 기반의 패스워드를 예측하는 연구의 동향에 대해 알아본다.

Polymer materials are used in a wide variety of fields such as automobiles, aerospace, energy, IT, and as well as simple household products. Despite high interest in the technological convergence of polymer materials for the sustaining progress, there have been only limited analyzes on the topic. This research attempted to analyze the types of convergence and the level of technology in the polymer materials field. For this purpose, we collected patent information from the PCT database and implemented a co-classification analysis. The research shows that Japan and Korea have more section-level convergence whilst US and Europe focus on field-level convergence. In terms of the quality measured by patent activity, patent competitiveness, and patent effect, Korean convergence technologies seem to be inferior to those of other countries.

Environmental monitoring sub-system has been developed using gas sensor module, Bluetooth module and PDA phone. The gas sensor module consists of $NO_2or$ CO gas sensor and signal processing chips. Gas sensor is composed of the micro-heater, sensing electrode and sensing material. Metal oxide nano-material was selectively deposited on a substrate with micro-heater and was integrated to the gas sensor module. The change in resistance of the metal oxide nano-material due to exposure of oxidizing or deoxidizing gases is utilized as the principle of this gas sensor operation mechanism. This variation detected in the gas sensor module was transferred to the PDA phone by way of Bluetooth module.

We propose a novel post-processing algorithm and its very-large-scale integration architecture that simultaneously uses the passive and active stereo vision information to improve the reliability of the three-dimensional disparity in a hybrid stereo vision system. The proposed architecture consists of four steps - left-right consistency checking, semi-2D hole filling, a tiny adaptive variance checking, and a 2D weighted median filter. The experimental results show that the error rate of the proposed algorithm (5.77%) is less than that of a raw disparity (10.12%) for a real-world camera image having a $1,280{\times}720$ resolution and maximum disparity of 256. Moreover, for the famous Middlebury stereo image sets, the proposed algorithm's error rate (8.30%) is also less than that of the raw disparity (13.7%). The proposed architecture is implemented on a single commercial field-programmable gate array using only 13.01% of slice resources, which achieves a rate of 60 fps for $1,280{\times}720$ stereo images with a disparity range of 256.

This research focus on the economic activity as consumer and producer traits of future customers in the convergence age. We assess level of convergence for digital devices and services respectively by questionnaire survey and interview for 14 professions. And then, for evaluating convergence level and usage of digital services of each respondents, we conducted the questionnaire survey for 343 samples. Findings of our research hold that the group who showed higher level of convergence tends to use the socialized digital services more. Convergence generation were heavy users in appstore on smart-phone and wireless game and more participating. In digital service area, facebook/cyworld, twitter, UCC, portal, internet community in digital service. Convergence generation are global network communication, buying decision making activity, actively opinion expression, prosumer attitude, dependency on digital device, experience based purchase behavior, enthusiastic information sharing.

Convergence being process varietly and quickly, with complex products and services based on digital technology and with start its creating new form of products and service, influenced to diversity of consumers need, and social trend. Thus, in this paper, convergence it presents the application instance according to variation of the convergence commit, and observed the advantage which is the possibility of appearing from here, it has the necessity of the effect and the policy preparatio, appearing on it try the electronic government of domestic convergence with role of the u-Gov due to an evolution with convergence, for it attains the administrative idea which u-Gov pursues. And by convergence analysis of issue, hereafter it presented a policy propulsion direction of convergence.

Energy and environment problem has been arisen and become one of the major concerns all over the world, due to scarce energy resources and inefficient energy consumption. Recently, energy-IT(EIT) convergence technology has been getting more attention, being expected to be one of key technologies to resolve the problem, and R&D projects on various areas of EIT convergence technologies have been launched in many countries on a large scale. Korea government and companies have also been interested in the development of EIT technologies, however, the scopes of technology areas are limited to just a small part such as smart grid technology. This paper investigates effectiveness of each EIT convergence technology and deduces EIT convergence technologies using AHP(Analytic Hierarchy Process). It is expected that our research could be meaningful information supporting policies on R&D projects of EIT convergence technologies promoted to save energy and strengthen the national competitiveness. Our research results show that the EIT convergence technology area of green building would be the most effective EIT convergence technology except smart grid, and network-based energy management system would be the most effective amongst the sub-areas of green building.

Recently, due to the spread of the Korean Wave, as worldwide interest in Korean culture and the appearance of Korean celebrities increases, overseas expansion of Korean beauty companies have been activated. Despite the global economic downturn, Beauty Industry is continuing to grow, Korea's growth rate is remarkable level. Despite this growth in order to maintain a steady growth since the beauty industry is small and polarization based on the Beauty-IT Convergence Technology creates new markets, that require development of Beauty-IT Convergence Industry. For the status and prospects of the Beauty Industry, some research has been carried out, not all the studies carried out so far for Beauty-IT Convergence Industry. Therefore, this study is significant that Beauty-IT Convergence Industry's first research. The global Beauty-IT Convergence Industry is at the beginning yet, tThe government selected research topics of Top-Down approach to Beauty-IT Convergence technology, granted extra points, supported by establishing long-term Technology Roadmap as other industries, such as by establishing a global market strategy for the systematic occupation and promising technology development planWe will get focused training.

Basically, the mis-convergence, which is inevitable in CRT Projection TV. is the degree of deviation of red and blue from green beam. The cause of mis-convergence is the change of magnetic field and electrical characteristic in deflection circuits and convergence amplification circuit. A new and easily implementable mis-convergence compensation algorithm is presented in this paper. The proposed algorithm does not needs any compensation devices. It uses only TV OSD and a remote controller and anyone who wants to compensate can easily correct the mismatch. Through real compensation experiments, it is found that the proposed algorithm is useful and effective one.
