인터넷의 폭발적인 성장에 힘입어 '정보사회', '가상공간'이라는 용어가 더 더욱 혼란스럽게, 그렇지만 당연시되어 사용되고 있다. 현대세계의 핵심적 특성으로서 '정보'와 '미디어'에 일부 사회이론가와 대부분의 일반인은 매료되어 있으며, '지식이 가치의 원천이고 세계를 움직이는 것은 정보이다.' 라는 식의 검증되지 않은 주장을 쉽게 하고 있다. 이에 보드리야르는 현대문화를 기호(signs)의 문화로 정의하고, 우리는 기호와 의미화 양식으로 둘러싸여 있으며, 모더니티의 주장과 같이 기호의 배후에 어떤 실체가 있는 것이 아니라 단지 기호만이 존재한다고 주장한다. 따라서 우리는 비진정성(inauthenticity)을 벗어날 수 없으며 그렇게 할 수 있다고 주장하는 것은 전혀 타당하지 못하다는 것이다. 사람들이 기호가 시뮬라시옹에 불과하다는 것을 닫고 있다면 무엇이든 괜찮게 된다 - 그리고 아무것도 괜찮지 않게 된다. 그리하여 보드리야르의 결론, 즉 "우리는 아무 것도 볼 것이 없는 이미지를 대량으로 만들어낸다. 오늘날 대부분의 이미지는... 아무 것도 볼 것이 없는 문자 그대로 이미지이다." 라는 것에 도달하게 된다. 따라서, 이러한 세계는 의미 없이 보여지고 경험되기 위한 그리고 즐겨지기 위한 기호를 가지게 되는 포스트모던한 세계이며, 이러한 예들은 인터넷등 미디어에서 폭발적으로 보여지고 있다. 즉, 관객들은 아무 것도 보거나 듣지 않으며 단지 현대를 특징 짓는 볼거리들을 경험할 뿐이라고 결론 내릴 수 있다. 본 연구는 정보와 미디어의 새로운 디자인 패러다임에 정보의 긍정적 사회 현상뿐 아니라, 비판적 사상을 검토해 봄으로써 미디어를 바라보는 디자인 철학과 방향에 도움이 되고자 하는데 그 목적이 있다.

With the development of cloud computing, internet technology and Internet of Things(IoT), most of applications are being smarter and changing from native application to SaaS (Software as a Service) application. New versatile SaaS applications are being released through various app portals (e.g. appstore, googleplay, T-Store, and so on). However, a user has a difficulty in searching, choosing an suitable application to him. It is also hard for him to know what functions of each SaaS application are useful. He wants to be recommended something inter-operated SaaS service according to his personality and his situation. Therefore, this paper presents a way of making mash-up of SaaS applications in order to provide the most convenient inter-operated SaaS service to user. This paper also presents SaaS Application Mash-up Framework (SAMF), complex context and rule matrix. The proposed SAMF is a main system that totally manage SaaS application mash-up service. Complex context and rule matrix are key components in order to recommend what SaaS applications are needed and how those SaaS applications are inter-operated. The SAMF collects complex contexts (User Description, Status Description, SaaS Service Description) in order to choose which SaaS applications are useful, analyze what functions to use, how to mash-up.

기존의 방송 단말에서 제공되는 IoT 서비스는 방송과 연계되지 않은 독립형 서비스의 형태로 제공되고 있었으나 최근 하이브리드 방송 관련 기술의 확산으로 방송과 IoT가 유기적으로 연계된 다양한 서비스로의 발전이 기대되고 있다. 하지만 현행 IoT 서비스는 다양한 프로토콜이 혼재된 클라우드 형태로 구성되어 임베디드 어플리케이션인 하이브리드 방송 단말에서의 접근에 많은 제약을 가지고 있다. 이러한 문제를 해결하기 위해, 본 논문에서는 Fog Computing의 개념을 어플리케이션으로 확장한 하이브리드 방송용 Fog Applet 아키텍쳐를 제안한다. Fog Applet 아키텍쳐는 클라우드 기반 IoT 서비스와 방송 단말 어플리케이션 사이에 Fog Applet을 위치시킴으로써 임베디드 어플리케이션의 서비스 접근 요구를 감소시키고 다양한 클라우드 기반 IoT 서비스와 유연한 구성을 제공하는 목적을 가진다. 제안된 아키텍쳐는 하이브리드 방송 기반의 서비스 환경에 대한 구현을 통하여 다종 IoT 서비스의 연동을 지원하는 하이브리드 어플리케이션의 구현을 통하여 그 기능을 검증한다.

Traditionally used for networking computers and communications, the Internet has been evolving from the beginning. Internet is the backbone for many things on the web including social media. The concept of social networking which started in the early 1990s has also been growing with the internet. Social Networking Sites (SNSs) sprung and stayed back to an important element of internet usage mainly due to the services or provisions they allow on the web. Twitter and Facebook have become the primary means by which most individuals keep in touch with others and carry on substantive conversations. These sites allow the posting of photos, videos and support audio and video storage on the sites which can be shared amongst users. Although an attractive option, these provisions have also culminated in issues for these sites like posting offensive material. Though not always, users of SNSs have their share in promoting hate by their words or speeches which is difficult to be curtailed after being uploaded in the media. Hence, this article outlines a process for extracting user reviews from the Twitter corpus in order to identify instances of hate speech. Through the use of MPCA (Modified Principal Component Analysis) and ECNN, we are able to identify instances of hate speech in the text (Enhanced Convolutional Neural Network). With the use of NLP, a fully autonomous system for assessing syntax and meaning can be established (NLP). There is a strong emphasis on pre-processing, feature extraction, and classification. Cleansing the text by removing extra spaces, punctuation, and stop words is what normalization is all about. In the process of extracting features, these features that have already been processed are used. During the feature extraction process, the MPCA algorithm is used. It takes a set of related features and pulls out the ones that tell us the most about the dataset we give itThe proposed categorization method is then put forth as a means of detecting instances of hate speech or abusive language. It is argued that ECNN is superior to other methods for identifying hateful content online. It can take in massive amounts of data and quickly return accurate results, especially for larger datasets. As a result, the proposed MPCA+ECNN algorithm improves not only the F-measure values, but also the accuracy, precision, and recall.

ICT 분야에서 2014년의 주목할 만한 이슈 중 하나가 "입는 컴퓨터(Wearable Computer)" 즉 "Wearable Device" 시대의 개막이다. 삼성 갤럭시 기어, 구글 글래스, 그리고 애플 워치와 같은 제품들을 웨어러블 디바이스라고 한다. MIT 미디어 랩의 정의에 따르면 웨어러블 디바이스는 신체에 부착하여 컴퓨팅 행위를 할 수 있는 모든 것을 지칭하며 일부 컴퓨팅 기능을 수행할 수 있는 애플리케이션까지 포함하고 있다. 웨어러블 디바이스는 또 하나의 두뇌다. 웨어러블 디바이스가 대중화되면 달라지는 것이 수없이 많아질 것이다. 일단 두 손이 자유로워진다. 내 몸이 24시간 인터넷과 연결되기 때문이다. 단지 스마트폰이나 디바이스를 몸에 붙인다는 수준이 아니라 디바이스가 바로 우리 몸의 외부에 연결되어 있는 두뇌 역할을 하게 될 것이다. 본 논문에서는 이러한 웨어러블 디바이스의 기술 요소를 관련 기업들 별로 분석해 본다.

In this paper, IoT(Internet of things) technology, which is the core of the 4th industrial revolution, was applied to the study of reduction of consumption current. The IoT is a sensor that collects data, a sensor communication, a gateway that processes and stores the collected data. Data application of IoT technology is applied to smart home, smart city, healthcare, smart factory, etc. and it needs to be applied to various industrial fields. By sensing the location of the sensor device, the specific functions of the gateway and the platform are turned ON and OFF to reduce the consumption current of the equipment during the OFF period. When the sensor device accesses the gateway, the specific function of the gateway is turned ON and When the device is separated from the gateway, it senses the sensitivity of the wireless signal and automatically turns off the certain functions. As a resurt, it has reduced the consumption of current. In this paper, we propose a novel system for detecting the location of sensor devices by applying IoT technology. The system implementation is realized by software based, and defines the requirements for the implementation of the sensor device gateway. The gateway automatically detects the location, movement of the device and performs necessary functions. Finally verifies the automatic detection performance of the gateway according to the location of the device. It will contribute greatly to the development of the smart city and office.

Ryuseo(類書) is a type of traditional books and seems like today's encyclopedia. For compilation of this book, the contents with good ideas and the improvement in method of editing are very important. The process of development, basic form, reception and transformation, the method of succession in today were investigated with the traditional Ryuseo through this study. In Korea, the publishing of this book in the beginning was just republishing of Chinese Ryuseo. During the reign of king Sunjo of Chosun dynasty, Ryuseo for Korean, "Daedongeunbugunok(大東韻府群玉)" was published. Also the basic form of Ryuseo had to be changed in this period. Kimyuk increased practical use of this book by summarizing "Samunryuchui(事文類聚)". The first complete Korean Ryuseo was "Kosachalyo(故事撮要)" that was published in 1554, king Myungjong. In the book was included contents about diplomacy and daily life by Eosukkwun. In 1771, king Youngjo, "Kosashinseo(故事新書)" was published. It had more information about actual life than Kosachalyo. Ryuseo should be considered with two things when it is read by modern readers. One is the development of material for study and another is to ensure the readers. So Ryuseo could be a good basic material for developing contents of internet. Reproduction of this book by new one should be considered with increasing its function. Because reforming classical material by digital one is necessary for daily life in today.

Recently, greedy algorithm has received much attention as a cost-effective means to reconstruct the sparse signals from compressed measurements. Much of previous work has focused on the investigation of a single candidate to identify the support (index set of nonzero elements) of the sparse signals. Well-known drawback of the greedy approach is that the chosen candidate is often not the optimal solution due to the myopic decision in each iteration. In this paper, we propose a tree search based sparse signal recovery algorithm referred to as the tree search matching pursuit (TSMP). Two key ingredients of the proposed TSMP algorithm to control the computational complexity are the pre-selection to put a restriction on columns of the sensing matrix to be investigated and the tree pruning to eliminate unpromising paths from the search tree. In numerical simulations of Internet of Things (IoT) environments, it is shown that TSMP outperforms conventional schemes by a large margin.

Electrodes are an important part of electrocardiography (ECG); disposable electrodes have been extensively used. However, personal ECG monitoring devices for Internet of Things applications require reusable electrodes. As there have been no systematic studies on the characteristics of reusable electrodes to date, we conducted this study to assess the performance and feasibility of electrodes with different materials. We built reusable electrodes using twelve different metallic materials, including commonly used copper, silver, zinc, plating materials, chemically inert titanium, stainless steel, and aluminum. Each electrode was fabricated to a size of $5{\times}10mm$. Their characteristics such as offset, baseline drift, stabilization time, and chemical inertness were compared. A personal ECG monitoring system was used to test the manufactured electrodes. The performances of the Ag, Cu, and Zn electrodes were better than the performances of other electrodes. However, these materials may not be used owing to the chemical changes that occur when the electrodes are in contact with the skin, such as discoloration and corrosion, which deteriorate their electrical characteristics. Titanium, stainless steel, and aluminum are chemically stable. The titanium electrode showed the best performance among the three, and it is our recommendation as a material for manufacturing reusable electrodes.
