본 연구에서는 우리나라 중소기업에서 ASP 기반 회계정보시스템의 사용의도에 영향을 미치는 요인을 8개로 구분하여 분석하였다. 분석결과 첫째, 정보공유성은 ASP기반 회계정보시스템 사용의도 결정에 유의한 영향을 끼치고 있으며 둘째, 재무 전략적 기대 역시 유의한 영향을 끼치고 있었고 셋째, 회계정보자산 특수성도 ASP기반 회계정보시스템 사용의도 결정에 유의한 영향을 미치고 있으나 회계정보의 질적특성, 회계 정보의 보안성 및 맞춤화, 그리고 정보시스템 성숙도 요인은 사용의도에 미치는 영향이 미미한 것으로 확인되었다.

This study is designed to find out the causal relation between social support, career capability, career decision-making self-efficacy and career adaptability for the career interrupted women. For this purposes the scales of social support, career capability, career decision related self efficacy and career adaptability were used. For this study, the questionnaires were distributed from Mar. 2, 2018 to Apr. 6, 2018 to 960 to the career interrupted women who had the experience of getting training at the vocational school, beauty school and women's centers located in Seoul and Gyeonggi area (composed of married women in their 30s and 50s who were receiving the education of beauty care for more than 1-9 months). 920 questionnaires got responded from the women and they were used for the final analysis with Cronbach's ${\alpha}$, exploratory factor analysis, factor analysis, frequency analysis and correlation analysis performed with SPSS program and the structural equation performed with AMOS program. The findings from the analysis are as follows; First, it was found that the structural model between career capability, social support, career decision related self efficacy and career adaptability are proper. Second, the path coefficient of the structural model was found to be statistically significant with respect to all of career capability, social support, career decision related self efficacy and career adaptability. Third, it was found that in the relation between career capability, social support and career adaptability, the career decision related self efficacy has the mediating effect. These results show that if the level of career adaptability is to be enhanced for the caber interrupted women, the career decision related self efficacy can make the critical role in addition to the career capability and social support. So, this study tries to offer the basic data required for the preparation of career and the development of future career for the success of career interrupted women going back to the workplace.

With a recent rise of various chatbot services, this study attempts to explore the role of chatbot users'' psychological characteristics by applying the self-determination theory. In particular,this study investigates (a) the relationship between chatbot users' psychological needs(perceived autonomy, perceived competence, perceived relatedness) and user satisfaction, continuous intention to use, and (b) the moderating effect of chatbot type and user motivations. Based upon a survey, the results revealed that perceived autonomy, competence, and relatedness had significant positive effects on user satisfaction and continuous intention to use. The results also confirmed that the user satisfaction had a significant positive effect on the continuous intention to use. The moderating effect of social and relational motivation was found between perceived autonomy, competence, relatedness and user satisfaction. The implications are discussed for furthering the development of chatbot services.

We categorize the model of simple payment into Magnetic Secure Transmission, Near Filed Communication, and App Card based on the Focus Group Interview. We also define the key drivers for the diffusion of simple payment services based on the literature review with the experts. Through Analytic Hierarchy Process our finding suggests that the degree of acceptance at the stores is the most critical factor which decides the diffusion of simple payment service model. Security is also the important driver but due to the fact that service providers should follow the information security rule and supervisory guidance, it actually did not make a big difference in terms of assessing competence of each model.

This study addresses the issue of which factors make domestic works have turnover intention. To pursue this research issue, we utilized a public database "2017 Occupational Migration Path Survey", administerd by Korea Employment Information Service (KEIS). Decision tree method was applied to extract crucial factors influencing workers' turnover intention. They include 'the degree of matching the level of education with the level of work', 'the possibility of individual development', 'the job-related education and training', 'the promotion system', 'wage and income', 'social reputation for work' and 'the stability of employment'.

원자력발전소의 안전성을 평가하는 확률론적 안전성평가(PSA) 기법 내에서 인간신뢰도분석(HRA： Human Reliability Analysis)은 파악된 사고경위 중 부적절한 인적행위사건에 대한 분석 및 평가를 담당하고 있다. 여러 HRA 전문가들이 제기하고 있는 기존 PSA HRA의 개선점 중 정성적 분석 관점에서 중요하게 고려되는 사항을 정리하면 다음과 같다. 첫째, 운전원의 진단 및 상황판단 또는 의사결정 단계에서의 특정한 오류 유발사항(error producing conditions or error forcing context)을 분석할 수 있는 방법이 필요하며, 둘째, 다양한 인적오류사건의 고려이다.(중략)

To investigate the electromagnetic interference shielding efficiency (EMI SE) property based on heat treatment effects of carbon fibers in various temperatures, the polyacrilonitrle-based carbon fibers were prepared by electrospinning method and treated at 1073, 1323, 1873 and 2573 K. The surface morphology of carbon fibers was investigated by using FE-SEM and the carbon crystallization was studied by Raman spectroscopy based on effects of reaction temperatures. The electrical conductivity was obtained by measuring the surface resistance with four probe method on carbon crystallization. The permittivity, permeability and EMI SE were investigated by using S-parameter in the range of 800~4500 MHz. In case of carbon fibers treated at 2573 K, the improved carbon crystallization was confirmed by Raman spectrum and the enhanced electrical conductivity showing 54.7 S/cm was also observed. The permittivity was dramatically improved by factor of 4 based on effect of high reaction temperature. Eventually, the highly improved EMI SE value was obtained showing around 41.7 dB.

그동안 지역혁신체제론의 관점에서 지역연구개발시스템의 효율성을 분석하는 다양한 연구가 수행되었다. 하지만 (1)지역연구개발시스템의 내부 처리과정 고려 미흡과 (2)연구개발의 특수성을 고려하지 못한 효율성의 분석모형 설정, (3)투입 산출지표 설정의 타당성 부족, (4)산출된 효율성 지수의 민감도 분석 소홀 등의 여러 한계점이 존재한다. 특히 5~10년 이내의 단기간으로 접근함에 따라 지역연구개발시스템의 효율성이 어떻게 변모해왔는지 그 역동성을 상세히 고찰하지 못하였다. 따라서 본 연구에서는 1999년~2014년까지 16개 광역지방자치단체를 대상으로 네트워크 자료포락분석(Network Data Envelope Analysis: DEA)의 2단계 접근법(two-stage approach)을 활용해서 지역연구개발시스템의 효율성을 분석하고 주요 개선방향들을 논의하였다.

본 논문에서 최신구간을 활용하여 패턴의 최신성을 보장하고 최신구간내 패턴의 누락 없이 모든 패턴을 발견할 수 있는 점진적 로그 분석 기법을 제안한다. 즉, 주기마다 최신구간이 이동되면서, 동시에 패턴의 최신성 여부가 결정되고, 이동된 최신구간내 패턴이 될 후보 패턴을 미리 예측하여 보다 합리적인 패턴 관리할 수 있다. 따라서 일반적인 점진적 로그 분석 기법에서 간과된 대량의 로그에 숨겨진 패턴은 적어도 해당 최신구간내에서 모두 발견될 수 있고 최신성도 보증된다.
