The introduction of smartphone caused the most revolutionary change in the domestic telecommunications market after the digital revolution. However, due to the saturation of the local market, it is expected to post negative growth in 2016 and the sales of national communication carriers is in stasis. Thus, the smartphone industry is starting to shift its marketing efforts to secure the silver generation who still has room for increase in the rate of smartphone usage. As the silver generation has physical limitations and differences in needs, the marketing strategy based on the smartphone utilization is not appropriate. This study suggests the new silver generation, who has high income level and similar characteristics to the younger generation, as the new customer segment for smartphone. We analyze the effects of the major variables of UTAUT on smartphone use, as well as examine how these relationships differ between the new silver and the net generation. We verified the hypotheses using a survey with 309 smartphone users. The research findings supported the hypotheses regarding the effects of performance expectancy, effort expectancy and facilitating conditions on smartphone use, but did not support the hypothesis on the effect of social influence. The result of the group comparisons showed that both generation have similar characteristics on innovativeness and cognitive absorption, but the moderating effect of age on performance expectancy, effort expectancy and use is stronger in conjunction with the new silver generation. The study results are expected to be used in establishing a marketing strategy for the new silver generation.

ACT ON THE CONSUMER PROTECTION IN THE ELECTRONIC COMMERCETRANSACTIONS, ETC.(hereinafter The Act) provides legal liabilities of mail orderbroker and means for protection of consumers. However, I believe there are manyloopholes in the protection of consumers because The Act also provides lots ofexemption on legal liabilities of mail order broker. Korean Congress has submitted eightrevised bills to tighten consumer protection under The Act and two of those bills haveprovisions which tighten liabilities and duties of mail order brokers. Despite of therevised bills, those also have many weak points due to the inconsistent definition of legalterms and broad exemptions of legal liabilities of mail order brokers in The Act. Because I believe consistent revision is improbable due to the inconsistent legal termsin the revised bill, mail order brokers should be subdivided into a broker who hasrelation with the transaction and a broker who provides information as Korean FTCprovides and the legal liabilities of mail order broker should also be reduced followingthe revision. The revised bills should provide some provisions that mail order brokers have a dutyto notify the terms and conditions before making contract and that requesters of mailorder brokerage have a duty to provide and to confirm the information. Moreover, formore protection of consumers, the revised bill should also impose a broker who providesinformation and thus who has responsibilities in the transactions, in other words, abroker who has relation with the transaction on additional duties by decreasing theexemptions. The intent of Congress may be recognized in the bills, and the intent is consistent withpurpose in viewpoint of society. I hope the revised bills be a new act which contributedevelopment of national economy which is the purpose of The Act by increasingconsumer protection and by increasing the market credibility.

이충훈 ( Chung Hun Lee ),맹윤호 ( Yun Ho Maeng ),이중정 ( Choong C Lee ) (주)엘지씨엔에스(구 LGCNS 엔트루정보기술연구소) 2015 Entrue Journal of Information Technology Vol.14 No.2
프라이버시를 중요하게 생각하지만 그에 부합하지 않게 행동하는 것을 프라이버시 패러독스(Privacy Paradox)라고 한다. 이러한 사용자의 프라이버시 패러독스가 가장 많이 일어나는 온라인 서비스가 SNS이며, 프라이버시 침해나 범죄의 원인이 되고 있다. SNS 사용자의 자발적인 개인정보 공개로 발생한 문제는 기업의 이미지 실추와 재무적 손실까지 초래할 수 있다. 따라서 사용자의 개인정보 관리는 SNS 제공자에게 중요한 관리 요소이며, 사용자 간의 관계형성을 기반으로 하는 SNS 특성을 고려할 때, 프라이버시 패러독스는 개인정보 관리에서 중요한 고려사항이다. 본 연구에서는 동기이론을 적용하여 SNS 사용자의 프라이버시 패러독스를 유발하는 내·외적 요인들을 종합적으로 분석하였다. 연구결과, 내적 요인보다는 외적 요인이 프라이버시 패러독스를 유발하는 것으로 나타났다. 그리고 내적 요인에서는 인지된 행동통제가 부주의한 개인정보 제공에만 영향을 미쳤으며, 외적 요인에서는 주관적 규범, 기업 명성이 부주의한 개인정보 제공과 공개에 영향을 주고 보상은 부주의한 개인정보 공개에만 영향을 미치는 것으로 검증되었다. 본 연구결과는 SNS 제공자들이 사용자들의 프라이버시 관련 행동을 이해하는 데 있어서 유용한 참고자료가 될 것으로 기대한다. Privacy paradox is online users` careless behavior opposite to careful attitude in the protection of their personal information. It has often arisen on SNS and has become the source of privacy invasion or crime. The problems caused by SNS user`s volutary disclosure of personal informaton can result in the fall of company image and finacial losses. Therefore, the protection of users` personal information is critical to SNS providers, and considering SNS based on the relationship among users, privacy paradox is the important consideration in personal informaton protection. This study aims to investigate the factors affecting the SNS users` privacy paradox based on motivation theory which can analyse them in both intrinsic and extrinsic aspects. The research findings showed that the extrinsic factors were the causes of the privacy paradox. To be specific, perceived behavioral control was the only affecting factor on inconsistent provision of personal information in the intrinsic aspect, and subjective norm and corporate reputation had significant relationship with inconsistent provision and disclosure of personal information in extrinsic aspect. On the other hand, compenstion had the only effect on inconsistent disclosure of personal information. The study results are expected to provide considerations for SNS provoiders to understand users` behavior related to the privacy.
정보보호관리체계(ISMS) 항목의 중요도 인식과 투자의 우선순위 비교 연구
이중정(Choong-Cheang Lee),김진(Jin Kim),이충훈(Chung-hun Lee) 한국정보보호학회 2014 정보보호학회논문지 Vol.24 No.5
최근의 개인정보 유출과 같은 정보보안 사고들이 기업의 매출 감소와 이미지 손실에 직접적인 영향을 주는 심각한 위험 관리 요소가 됨에 따라 체계적인 정보보호 관리를 위해 정보보호관리체계를 도입하는 기업들이 증가하고 있다. 그러나 기업 내 정보보호 인식과 달리 적은 투자로 인해, 한정된 예산으로 다양한 정보보호 요소들을 효과적으로 관리할 수 있는 방안이 중요해지고 있다. 본 연구에서는 정보보호관리체계의 13개 항목들에 대해 정보보호전문가들의 중요도 평가를 통해 우선순위를 도출하여, 단계적으로 정보보호관리체계를 구축할 수 있는 방향을 제공한다. 그리고 각 항목들에 대한 투자 정도도 평가하여 중요도와 투자 간의 우선순위 차이를 비교·분석하였다. 연구 결과 침해사고 관리가 가장 중요한 것으로 나타났으며, 투자 정도에서는 IT 재해복구가 가장 높은 것으로 확인되었다. 그리고 정보보호 중요도와 투자 간의 우선순위 차이가 큰 정보보호 항목은 암호통제, 정보보호정책, 정보보호교육, 인적보안으로 확인되었다. 본 연구 결과는 정보보호관리체계 도입을 고려하거나 운영 중인 기업들이 한정된 예산을 고려하여 효과적인 정보보호 투자에 대한 의사결정 자료로 활용될 수 있을 것으로 기대한다. Recently, organizational efforts to adopt ISMS(Information Security Management System) have been increasingly mandated and demanded due to the rising threat and the heavier cost of security failure. However there is a serious gap between awareness and investment of information security in a company, hence it is very important for the company to control effectively a variety of information security threats within a tight budget. To phase the ISMS, this study suggests the priorities based on evaluating the Importance of 13 areas for the ISMS by the information security experts and then we attempt to see the difference between importance and investment through the assessment of the actual investment in each area. The research findings show that intrusion incident handling is most important and IT disaster recovery is the area that is invested the most. Then, information security areas with the considerable difference between priorities of importance and investment are cryptography control, information security policies, education and training on information security and personnel security. The study results are expected to be used in making a decision for the effective investment of information security when companies with a limited budget are considering to introduce ISMS or operating it.

We have synthesized silicon nanowires by using RFCVD(Radio Frequency Chemical Vapor Deposition) system on Au deposited p-type Si(100) wafers, and investigated their physical and electrical properties. The silicon nanowires had been grown in the atmospheres of $H_{2},\;N_{2}\;and\;SiH_{4}$ at 10 Torr at the substrate temperatures of $700{\pm}5^{\circ}C\;and\;810{\pm}5^{\circ}C$ respectively. FE-SEM analysis revealed that diameters of the silicon nanowires are $50{\sim}60nm$ with the length of several ${\mu}m$. XRD analysis showed that the growth direction of the nanowires is Si[111]. Field emission characteristics showed that the turn-of voltages at the current of $0.01\;mA/cm^{2}$ are $10\;V/{\mu}m\;and\;8.5\;V/{\mu}m$ for the wires grown at $700{\pm}5^{\circ}C\;and\;810{\pm}5^{\circ}C$, respectively.
