이 연구에서는 서로 다른 사용자 인터페이스의 대화 방식에 따라 PC통신 소프트웨어 의 사용편이성이 어떻게 달라지는가를 살펴보고자 한다. 이를 위해 현재 국내에서 이 용되고있는 3개의 PC통신소프트웨어를 대상으로 남녀대학생 18명에 의한 사용편이성 평가 시험을 실시하였다. 시험은 강사에 의한 1:1 방식에 의해 실시하였다. 평가척도로 는 학습소요시간, 시험소요시간, 정답률을 이용하였다. 실험결과, 윈도우환경에서 구현 되는 메뉴, 아이콘, 명령어를 혼합한 대화방식의 소프트웨어보다도 도스환경에서 구현된 명령어 대화방식의 소프트웨어가 학습용이성 측면에서의 사용편이성이 높을 수 있다는 점이 시사되었다.

인터넷을 활용한 전자상거래는 인류가 경험해 보지 못한 가장 크고 효율적인 유통시스템이다. 다가오는 21세기에는 정보산업의 핵심이 현재의 정보기술 관련 산업에서 인터넷 유통으로 변화할 것으로 기대된다. 인터넷 상점의 사용용이성은 전자상거래의 활성화를 위하여 중요한 문제점으로 인식되고 있으나 이를 평가하기 위한 구체적이고 체계적인 평가벙법에 관한 연구는 많지 않은 실정이다. 본 연구에서는 인지과학분야에서 개발된 GOMS를 인터넷상점의 상용용이성 평가에 적절하도록 변형시키고, 이를 근거로 평가시스템(WebGOMS)을 개발하였다. 본 시스템을 이용하면, 인지과학이나 GOMS의 분석 경험이 많지 않은 일반 웹개발자도 쉽게 인터넷상점의 사용용이성을 평가하고, 개선된 디자인을 설계할 수 있을 것이다.

The purposes of this study are to examine the predictability of variables related to SNS intention to use in collaborative learning and provide some new implications. Based on Technology Readiness and Acceptance Model (TRAM), we hypothesized that optimism, innovativeness, discomfort, insecurity as personal disposition variables, subjective norm as a social variable, and perceived usefulness and perceived ease of use as cognitive variables would predict SNS intention to use. For this study, 274 'Share Leadership' students in E university completed surveys and it was analyzed by multiple regression analysis. The results of this study showed as follows. First, optimism, innovativeness, discomfort, and subjective norm predicted perceived ease of use. Second, optimism, insecurity, subjective norm and perceived ease of use predicted perceived usefulness. Third, subjective norm, perceived ease of use and perceived usefulness predicted SNS intention to use. From this, it is revealed that positive technology readiness predict much more than negative technology readiness do and the role of teacher and peers is very important.

This study aims to identify the effect that the perceived usefulness and perceived ease of use have on learner flow in e-learning community. Based on literature review and Technology Acceptance Model(TAM), a potential model and five hypotheses were suggested. Questionnaire was carried out among 62 members of one e-learning community for preparatory teacher Cronbach alpha of the questionnaire was.88. The collected data were analyzed through correlation analysis and path analysis. The results of this research are as follows. Three hypotheses were adopted: Perceived usefulness will affect on attitudinal flow, Perceived ease of use will affect on attitudinal flow. and Attitudinal flow will affect on behavioral flow. Two hypotheses were rejected;. Perceived usefulness will affect on perceived ease of use and Perceived ease of use will affect on behavioral flow. The model revised through the results of path analysis had good-fitness. That is. overall fit measures (RMSEA, CFI. NNFI). indexes that show the suitability of the model were quite good. Findings of this study suggested the important strategies for designing e-learning community in order to promote learner flow.

The purpose of this study is to carry out the exploratory study on the easiness of using smart phone applications for searching food service information based on consumer characteristics. Examining the attributes of the easiness of using smart phone applications for searching food service information, this study checks the order of priority in the attributes and analyzes the correlation among the constructs of easiness of use, along with the difference in easiness of use based on demographic characteristics. The survey was conducted to the users of smart phones who live in 3 areas such as Seoul/Kyongki, Daegu/Kyongbuk, and Busan/Kyongnam from Jan. 3-Feb. 3, 2011, and total 264 copies of questionnaire were used for the final analysis. The result showed that the respondents considered the functions of searching restaurants, recommended restaurants, and the popularity list more important among the measurement items of easiness of use, and there was highly positive correlation between easiness to select restaurants and communication functions among all the factors drawn. It was found that there was significant difference in the function of searching restaurants, practicality, the easiness to select restaurants, communication, and the easiness to select menu on areas.

본 연구는 인터넷 환경 하에서 Davis의 기술수용모델(TAM)을 확장한 것이다. 본래의 TAM 모델에서는 인지된 사용용이성(perceived ease of use) 및 인지된 사용편이성(perceived usefulness)이 시스템 사용을 설명할 때 가장 중요한 요인이라고 제안하고 있다. 그러나 TAM 모델은 실제 시스템 사용의 약 $40\%$만 설명하고 있어 이 모델의 확장이 필요한 편이다. 본 연구에서는 기존의 TAM 모델에, Flow 이론에서 언급된 "인지된 즐거움 (perceived enjoyment)" 및 혁신확산이론(IDT)에서 언급된 "일치성(compatibility)"을 추가하여 TAM 모델을 확장하여 사용하였다. 본 연구자가 근무하는 대학의 대학포탈(university portals) 웹사이트를 사용하여 이 모델을 평가하였다.

인터넷 뱅킹은 다른 정보시스템이나 웹기반 시스템에 비해 보안에 대한 우려가 높으면서, 다른 거래자들과의 사용자간 거래가 지원되는 P2P적 요소를 가지고 있다. 따라서 보안우려와 거래파트너는 인터넷 뱅킹 사용에 많은 영향을 주는 중요한 요소로 간주될 수 있다. 본 연구에서는 기존의 기술수용모형에 보안우려와 거래파트너 영향을 외부변수로 도입한 확장된 기술수용모형을 제안하였다. 이를 위해 기존에 사용하고 있던 유용성 대신에 편리성을 도입하였고 보안우려와 사용용이성 및 사용은 부( )의 관계, 거래파트너 영향과 편리성 및 사용은 정(+)의 관계에 의해 기존의 기술수용모형에 확장하였다. 실증적 검증을 위해 설문조사를 하였고 조사결과는 구조방정식에 의해 분석하여 만족할만한 모형적합도를 얻었고, '보안우려-사용용이성' 관계를 제외한 모든 가설이 채택되었다.

The accommodative facility test can be use the very benetit in visual function test. The purpose of this study was mainly to check the binocular function and to estimate the amount of accommodation with the hand held flipper. It was measured as the subjective time needed to clear an accommodative target (20/20 letters) at 40 em through +/-2.00 D flipper(Bernell Corp., USA). The subjects have an irrespective of sex and no eye disease. Seventy five of youth applicants participated for the accommodative facility test. The reagents using the flipper had higher expected value than the other reagents. In test for the binocular function, the accommodative facility test is a important part due to a serviceable and simple examination. Therefore, these binocular checkup have to be developed through a survey of normative value in the near future.

최근 개인용 컴퓨터 사용자들의 인터넷 사용이 빈번해지면서. 개인용 컴퓨터 시스템에 대한 다양한 네트워크 공격의 피해가 늘고 있다. 이에 개인용 방화벽이 개발되었으나 현재 대부분이 윈도우 시스템에 기반하고 있다. 하지만 최근 리눅스 시스템이 개인용 컴퓨터의 운영체제로 많이 사용되고 있고, 피해 사례가 상당히 많음에도 불구하고 아직까지 리눅스 기반 개인용 방화벽은 전무한 실정이다. 본 논문에서는 기존의 리눅스 기반 네트워크 방화벽에서 제공하는 기능들 외에 동적 정책 설정 기능과 악의적인 네트워크 프로그램 실행의 제어 기능들을 추가적으로 포함하는 리눅스 기반 개인용 방화벽을 설계하고 구현하였다.

The purpose of this study was to investigate the influence of consumers' shopping value(SV), ease of use(EOU), and usefulness(U) on their purchase intention(PI) in mobile shopping mall. Path hypotheses in structural equation model which was constructed for this purpose were verified. In addition, the research model was analyzed according to the groups classified by the level of purchase experience in mobile shopping mall. The survey was limited to the respondents in their 20s and 30s living in Seoul and other metropolitan areas who had purchased fashion products in mobile shopping mall. 411 useful data collected from on-line survey were analyzed by descriptive statistics, exploratory factor analysis, confirmatory factor analysis, reliability analysis, and pearson's correlation analysis using SPSS 21 and AMOS 19. The results of verifying the hypotheses were as follows: First, SV was composed of two factors which included hedonic shopping value(HSV) and utilitarian shopping value(USV). Second, the research model was verified as an acceptable model in explaining the influence of consumers' SV, EOU, and U on PI. Third, seven hypotheses among nine hypotheses were accepted in high purchasers. HSV did not have a significant influence on PI, and EOU did not affect PI significantly. Fourth, five hypotheses were accepted in light purchasers. HSV affected U significantly while USV had a significant impact on EOU and PI. EOU affected U, and U affected PI significantly. In conclusion, USV was proven to be the factor affecting PI directly as well as indirectly. Eou and U also had a significant influnce on PI in mobile fashion shopping. These results will provide mobile marketers with the differentiated strategies to make consumers lead to mobile purchase.
