his study classified the development process of artificial intelligence (AI) speakers through analysis of the news text of artificial intelligence (AI) speakers shown in traditional news reports, and identified the characteristics of each product by period. The theoretical background used in the analysis are news frames and topic frames. As analysis methods, topic modeling and semantic network analysis using the LDA method were used. The research method was a content analysis method. From 2014 to 2019, 2710 news related to AI speakers were first collected, and secondly, topic frames were analyzed using Nodexl algorithm. The result of this study is that, first, the trend of topic frames by AI speaker provider type was different according to the characteristics of the four operators (communication service provider, online platform, OS provider, and IT device manufacturer). Specifically, online platform operators (Google, Naver, Amazon, Kakao) appeared as a frame that uses AI speakers as'search or input devices'. On the other hand, telecommunications operators (SKT, KT) showed prominent frames for IPTV, which is the parent company's flagship business, and 'auxiliary device' of the telecommunication business. Furthermore, the frame of "personalization of products and voice service" was remarkable for OS operators (MS, Apple), and the frame for IT device manufacturers (Samsung) was "Internet of Things (IoT) Integrated Intelligence System". The econd, result id that the trend of the topic frame by AI speaker development period (by year) showed a tendency to develop around AI technology in the first phase (2014-2016), and in the second phase (2017-2018), the social relationship between AI technology and users It was related to interaction, and in the third phase (2019), there was a trend of shifting from AI technology-centered to user-centered. As a result of QAP analysis, it was found that news frames by business operator and development period in AI speaker development are socially constituted by determinants of media discourse. The implication of this study was that the evolution of AI speakers was found by the characteristics of the parent company and the process of co-evolution due to interactions between users by business operator and development period. The implications of this study are that the results of this study are important indicators for predicting the future prospects of AI speakers and presenting directions accordingly.

최근 들어 무선인터넷 및 모바일 컴퓨팅 기술의 급속한 발전과 함께 향후 그 수요가 폭발적으로 증대될 것으로 예상되는 분야가 위치기반서비스(LBS, Location Based Service) 기술이다. 이동통시산업이 발달한 미국 및 유럽의 선진국에서는 지난 수년에 걸쳐 지속적으로 축적되어 온 정보기술을 통하여 현재 수많은 LBS 관련 기술개발이 활발히 진행되고 있다. 1999년 미국의 FCC(미연방통신위원회)는 무선 E119 규칙을 제정하였는데, 이 규칙은 LBS를 주목하게 한 결정적인 계기가 되었다. FCC는 미국내의 망 사업자들이 2001년 10월까지 이동전화 사용자가 응급 호출(911)을 하였을 때 67%는 100M 이내의 위치오차로, 95%는 300M 이내의 위치오차로 응급호출자의 위치정보를 제공해야 한다는 규정을 제정했다. 이때부터 각종 관련 회사들이 생겨나기 시작했으며, 사람들이 LBS에 관심을 가지기 시작하였다. 국내에서도 이동통신사업자 및 IMT-2000 사업자를 중심으로 LBS 도입을 적극 준비하고 있는 상황이다. 그러나 위치정보라는 것은 오래 전부터 사람들이 알고있던 사항이다. 이미 GPS라는 것을 이용하여 국방분야, 환경분야, 교통 및 물류 분야에서 많이 활용되고 있었기 때문이다. 그런데 왜 같은 위치정보를 활용하는 분야인데 LBS는 이토록 많은 관심을 불러일으키는가? 그것에 대한 답변은 바로 위치정보가 이동통신망과 연결되면서 대중적이고 일반적인 서비스가 가능해졌기 때문이다. 특히, LBS는 GIS가 정보통신 기술과 융합되면서 앞으로 추구해야 할 차세대 정보기술 분야라는 점에서 그 의미는 더 크다고 할 수 있다. 평균(平均) 0.322였다. 그리고 RaA를 모핵종(母核種)으로 가정(假定)했을 때 각핵종간(各核種間)의 방사평형비(放射平衡比)는 대개 $C_1>C_2>C_3$인 것으로 나타났다. 여기서 $C_1,\;C_2$ 및 $C_3$는 각각 RaA, RaB 및 RaC의 농도(濃度)를 나타낸다.0cm 깊이에서는 Pythium균(菌)과 Fusarium균(菌)을 제외(除外)하고 모두 14일간(日間)에 사멸(死滅)하였다. 6. 최고(最高)에 달(達)했다가 최저(最低)에 이르는 온도(溫度)의 반복적(反復的)인 파동(波動)이 있는 것에서 없는 것보다 단시간(短時間)에 사멸(死滅)하였다. 이상(以上)의 결과(結果)에서 볼 때 하기고온기(夏期高溫期)의 재배(栽培) 휴한기(休閑期)에 PVC film을 사용(使用)하여 하우스를 밀폐(密閉)하거나 턴널을 만들어서 태양열(太陽熱)을 이용(利用)한 토양소독(土壤消毒)의 가능성(可能性)이 충분(充分)히 있는 것으로 생각된다.종합적(綜合的)으로 볼 때, diazinon 과 decamethrin의 처리(處理)는 포장(圃場)에서 벼멸구의 산란력(産卵力)과 성충수명을 증대(增大)시키고, 식이활동(食餌活動)을 촉진(促進)함으로서 벼멸구의 resurgence를 유발(誘發)하고 아울러 수도체(水稻體)의 hopperbun을 가속화시킬 가능성(可能性)이 있음을 알 수 있었다.는 점차 약하여 졌으나 catalase, invertase는 그 활성도가 일단 숙성중기에 높아졌다가 낮아졌다.n 이 pH 4.2이고 temperature는 $60^{\circ}C$이었다. 그리고

Providing trading partners with personal information to establish an e-commerce financial transaction is inevitable. Most e-commerce companies keep personal information and transaction data for user's convenience and develop additional services as their applications. However, keeping personal information increases the likelihood of identity theft causing direct or indirect damage while it may simplify repetitive financial transactions. This study introduces risk management methods based on quantitative and qualitative analysis including demand-supply curve model and Gordon & Loeb model to analyze the risks for security management. The empirical analysis with survey results from KISA (Korea Information Security Agency) shows that the root cause of different statistics of personal information leakage incidents according to core business of internet companies is the difference in their Loss Expectancy caused by them. Also we suggest disciplinary compensation and higher standard for personal information protection as a solution to prevent the variation of investment on it between individual companies.

Nowadays, Smart Wallet technology trend that is able to save users' consuming costs and also retain users' redundant behaviors such as Single-tapping, One-way communication, Integrated ID, has been issued in recent Mobile Industrial Fields. As one of Smart Wallet functions, Integrated ID is proposed for users' convenience, handiness, and immediate responses. It is designed for the effective management of users' IDs which are easy to be forgot because of its unusual structures. To be detail, instead of user, Integrated ID system can certificate users identification from various online sites (where user resisted) authorization requests via one-clicking, not putting identification data in each sites. So, this technology would be helpful much to a certain user who has lots ID and its Password in multiple Online shopping companies by establishing integrated ID. However, although Integrated ID has lots advantages to be used, most Mobile Service Companies has hesitated to apply Integrated ID service in their shopping systems because this technology requires them sharing their users' data. They have worried that this service would be not helpful to gain their profits. Furthermore, Users who join in multiple shopping companies and use Integrated ID services also are difficult to decide which company they have to save their points in before payment because this system could not show any financial benefit analysis data to their users. As following facts, via this paper majorly we propose the advanced Integrated ID system which concern shopping point management. Basically, this system has a strong security payment service and secure network services like other mobile Shopping systems. Additionally, this system is able to service (or to support) shopping -point -saving guide for customers' financial benefits and conveniences.

The purpose of this study is to analyze how the vertical integration, which is the main characteristic of the domestic digital music market, appears in each period and how these phenomena affect the digital music market. As a result, we could find out that the domestic digital music market is a vertically integrated market centered on ISPs. There were a variety of subjects that led the digital music market from the early digital music in 2000s to the latest streaming market. However, ISP was the only subject that vertically integrated all aspects of content, distribution, and consumption through its subsidiaries and affiliated companies. A variety of combined services, supplementary services, and fare plans provided by using its platform and network have become mainstream services in the domestic digital market and have fixed the current transaction type in domestic market.
