이 글은 한국에서 시기별 개인정보 유출에 대한 프레임이 어떤 형태로 변화하는지에 초점을 맞추고 있다. 이를 위하여 개인정보 유출이라는 텍스트가 등장하기 시작한 1984년도부터 현재까지 30년 간 걸쳐 보도된 신문기사의 제목을 수집하였다. 시기마다 형성되어 있는 지배적인 프레임을 도출하기 위하여 단순 빈도분석과 공동출현빈도 매트릭스 기반의 텍스트 네트워크 분석, 군집분석을 실시하였다. 사회연결망분석의 주요 지표인 연결중심성의 개념을 적용하여 시기별 주된 프레임을 밝혀내었다. 총 4시기에 걸쳐 프레임의 태동, 형성, 확장, 전환의 과정이 일어났는데, 개인정보에 대한 접근 및 보유주체가 주로 정부였다면 점차 전자상거래 등 고객맞춤형 서비스로 인해 민간 기업으로 확대되었다. 또한 초국가기업의 등장은 개인정보 유출의 경계를 자연스럽게 국내에서 국외로 확장시켰다. 빅데이터 시대의 엄청난 정보량과 데이터 생태계의 역동성은 새로운 정보보안위협으로 다가오고 있어 강력한 정보보호체계 설계가 시급함을 프레임의 전환을 통하여 보여주고 있다.

다양한 서비스를 제공하는 인터넷 환경에서 수많은 개인정보가 활용되고 있으나, 개인 사용자는 자신의 어떠한 개인 정보가 전송되는지 모르고 있다. 본 논문에서는 네트워크 패킷 내에 개인정보를 지속적으로 모니터링하고, 유출 여부를 사용자에게 알려주는 모니터링 도구 개발을 목표로 한다. 이를 위하여 개인정보 모니터링 도구를 구현하고, 그 결과를 분석한다. 또한 기업 기밀정보 유출 방지, 의료정보 유출 방지 등 직접 활용할 수 있는 응용 분야에 대해 제시한다. 본 연구 결과는 개인정보 유출 방지에 기여함으로써 개인정보를 대상으로 하는 다양한 사이버 침해를 줄이는데 기여할 수 있을 것으로 판단한다.

Recently, the popularity of Social Network Service (SNS) along with the spread of smart phone, personal computer and tablet PC helps personal network to construct new forms of services in cyberspace. As such, SNS plays a significant role in constructing diverse online networks and there is a growing interest on SNS at societal level. In this vein, the purpose of the research was to find the factors affecting the continuance intention to use social network services. The major findings are summarized as follows. First, "System Quality", "Contents Quality", "Personal Innovativeness", "Self-Efficiency", "Honor Benefit" has significant effects on "Relationship Quality". Yet, "Economic Benefit" is not statistically significant on "Relationship Quality". Second, "Relationship Quality" has a significant effect on "Continuous Usage Intention". Last, our research discovered the relationship between exogenous variables which would serve as valuable inputs in the development of strategic guideline and plan for SNS companies and related services.

Purpose Targeting Korean companies listed on Korean securities markets (i.e., KOSPI and KOSDAQ markets), this study aims to shed lights the effects of personal information security breaches on stock prices of information security companies. Interestingly, this study is, to the best of our knowledge, the first to examine the information transfer effect on personal information security breaches of companies. Design / Methodology /Approach To examine the information transfer effect of personal information security breaches, our study employs the event study commonly used in financial studies. To this end, we investigate a variety of events of personal information security breaches of companies listed on the KOPSI stock market and the KOSDAQ market. We collect the total samples of one hundred and twelve with forty seven of events of personal information security breaches by thirty companies and sixty five of information security companies. Findings The principal findings from the empirical study are as follows. First, for companies of personal information security breaches, our event study presents the significantly negative AAR (averaged abnormal return) value on the event day at the 5 % level and the highly significant negative CAAR(cumulative averaged abnormal return) value on the event day and the day after the event day at the 1 % level. The results suggest that personal information breaches significantly contribute to an decrease in value of the information breached companies. The cross sectional regressions in this study estimate the significantly negative coefficient for the ME/BE variable, the proxy for a growth opportunity at the 5 % level. This suggests a reverse relation between the growth opportunity of companies and their value. As for the various samples of the information security companies categorized by physical security, network and system security, security application software, code authentication, system integration, we find the significantly positive AAR on the day after the event day at the 5% level, only for the network and system security-companies. This addresses that the information transfer effect followed by personal information breaches is uniquely observable for companies categorized into network and system companies. The regressions for the network and system companies estimate the significantly positive coefficient for the NS dummy variable (i.e., the dummy of the network and system security companies) at the standard level. This allows us to identify appropriate times needed to make the information transfer effect realized from personal information breached companies to information security companies.

In the ubiquitous computing environments. people usually carry multiple information technology devices with them. Personal device network (PDN) refers to the way how people connect multiple IT devices for their personal as well as professional purposes. Even though it has been Quite popular to construct the PDN in ubiquitous computing context, not much research has been conducted on how people actually connected multiple devices and what influences their methods of connection. In this paper we conducted a content analysis on community bulletin boards of IT devices and a contextual inquiry with expert users of PDN for investigating the configurations with which users connect multiple IT devices. Base on the results of two related studies, we identified three major types of PDN configurations, and key factors that influence the configurations of PDN. We conclude this research with guidelines to design a set of devices for each of the three configuration types.

초고속 유/무선인터넷 기술의 급속한 발전으로 언제 어디서나 가능한 인터넷 비즈니스 현상이 전개되고 있다. 이 같은 환경 하에서 이동에이전트(mobile agents) 기술은 사용자를 대신하여 자율적으로 실행할 수 있는 소프트웨어 객체로서 이동성을 지원하기 때문에 개인 휴대단말기들을 위해 유용한 메커니즘을 제공한다. 따라서, 본 논문은 유/무선인터넷 환경 하에서 이동에이전트를 지원하는 휴대단말기용 이동에이전트 플랫폼을 개발 구현한다. 이를 위해, 이미 선행 개발된 자바(Java) 기반 이동에이전트 시스템인 JAMAS를 수정 갱신하여 휴대단말기용 시스템으로 구축한다. 제안된 시스템을 기반으로 하여 유/무선인터넷상에서 네트워크 환경을 구성하고 감시할 수 있는 휴대단말기용 SNMP(Simple Network Management Protocol) MIB(Management Information Base)를 접근하여 브라우징 하는 어플리케이션을 구현한다. 제안된 시스템 어플리케이션은 SNMP 에이전트의 관리 정보인 MIB를 접근하여 네트워크 맵 뷰어(map viewer), MIB 갱신 등을 브라우저를 통해 관리자에게 제공한다. 그러므로, 휴대단말기용 이동에이전트를 이용하면 홈 네트워크 관리, Mobile-Commerce, 원격지 DB 시스템 통합, Active Message, Active Network 관리 등을 확장성 있게 지원할 수 있다.

Personal Robot System in developing, have a module architecture, each module are connected through heterogeneors network systems like Ethernet, WLAN (802.11), IEEE1394 (Firewire), Bluetooth, USB, CAN, or RS-232C. In developing personal robot system we think that the key of robot performance is interoperability among modules. Each network protocol are well connected in the view of network system for the interoperability. So we make a bridging architecture that can routing, converting, transporting data packets with matcing each network's properties. Furthermore we suggest a advanced design scheme for realtime / non-realtime and control signal (short, requiring hard-realtime) / multimedia data (large, requiring soft-realtime). By some application systems, we could test performance, interoperability and stability. In this paper, we show our design concept, middleware architecture, and some applications systems using this middleware.

E-textile technology has earned a great deal of interest in many fields; however, existing wearable network protocols are not optimized for use with conductive yarn. In this paper, some of the basic properties of conductive textiles and requirements on wearable personal area networks (PANs) are reviewed. Then, we present a wearable personal network (WPN), which is a four-layered wearable PAN using bus topology. We have designed the WPN to be a lightweight protocol to work with a variety of microcontrollers. The profile layer is provided to make the application development process easy. The data link layer exchanges frames in a master-slave manner in either the reliable or best-effort mode. The lower part of the data link layer and the physical layer of WPN are made of a fabric serial-bus interface which is capable of measuring bus signal properties and adapting to medium variation. After a formal verification of operation and performances of WPN, we implemented WPN communication modules (WCMs) on small flexible printed circuit boards. In order to demonstrate the behavior of our WPN on a textile, we designed a WPN tutorial shirt prototype using implemented WCMs and conductive yarn.
