This work is intended to investigate how the factors of enterprise mobile SNS affect user satisfaction and continuous use intention through technology acceptance model proposed by Davis. To achieve the purpose, this researcher explored Information Systems Success model proposed by DeLone & McLean, Technology Acceptance Model proposed by Davis, and Model after Acceptance, and on the basis of the investigation, performed a study. For the data of this work, 9 enterprises, each of which has more than 100 employees and is located in Seoul, were chosen, and a questionnaire survey was conducted on their 276 employees who experienced enterprise mobile SNS. As a data collection tool, a structured self-administered questionnaire was used. For data analysis, SPSS 18.0 and AMOS 18.0 were used for applying Structural Equation modelling. According to the results of this work, three factors of enterprise mobile SNS-systematic factor (system quality, information quality, and service quality), user factor (personal innovation and personal familiarity), social factor (social effects and social interaction)-affected user satisfaction and continuous use intention through perceived availability, perceived easiness, and perceived enjoyment. Also, it was found that the direction of effects matched a theoretical prediction. And, it was revealed that the decision variables and mediating variables significantly affected user satisfaction and continuous use intention. Theoretical and practical meanings were discussed for the study result, and some suggestions were made for the issues of this work and future studies.

인자로 중대사고시 생성되는 흡습성(hygroscopic) 에어로졸의 거동을 해석적인 방법을 이용하여 분석하였다. 분석한 내용는 상대습도가 불포화, 포화, 과포화 조건에서 CsOH 에어로졸의 수증기 응축률, 입자성장에 따른 크기분포의 변화. 중력침전에 의한 전체 에어로졸량의 변화이다. 용질효과를 고려한 흡습성 에어로졸 모델을 사용한 경우 상대습도가 불포화 조건에서도 에어로졸 입자에 수증기 응축이 발생하며 입자의 크기가 평형반경에 달할 때까지 지속됨을 발견하였다. 이러한 입자 성장은 매우 빠른 입자크기분포 변화를 초래하여 중력침전에의한 급속한 에어로졸 감소를 초래하는 것으로 예측되었다. 따라서 현재 사용되고 있는 MELCOR 및 CONTAIN 코드는 흡습성 에어로졸에 대해서 용질효과를 고려한 모델을 사용하여야 할 것이다.

생성형AI(Generative AI, GenAI) 서비스는 단순/반복적인 업무를 자동화하고, 많은 일자리의 생산성 향상에 도음을 주어 전반적으로 기존 일자리 감소에 영향을 줄 것이다. 반면에 높은 수준의 생성형AI 기술을 낮은 비용으로 활용할 수 있게 하고, 예술, 게임, 미디어 산업 등 창작 영역과 플랫폼 기반의 서비스 출시에 도움을 주어, 창조적 아이디어에 기반한 소수의 인원이 참여하는 1인 창조기업에서 새로운 일자리 창출에 긍정적인 영향을 줄 것이다. 본 연구의 목적은 1인 지식 창업자라고 할 수 있는 컨설턴트, 강사들이 생성형AI의 강점인 창의성을 활용하여 업무 효율을 높이는 데 적극적으로 활용할 수 있도록 생성형AI 서비스 특성이 지속이용의도에 미치는 영향을 분석하는데 있다. 본 연구에서는 기술수용모델(TAM)을 활용하여 생성형AI의 서비스 특성인 효율성, 창의성, 의인화, 개인화 및 자율성이 지속이용의도에 미치는 영향에 관한 연구를 인지된 유용성과 인지된 이용 용이성을 중심으로 진행하였다. 따라서 본 연구에서는 생성형AI의 서비스 특성이 인지된 유용성과 인지된 이용 용이성을 증진하고, 인지된 유용성과 인지된 이용 용이성이 지속 이용의도에 영향을 미칠 것이라는 인과적 경로를 검증하고자 한다. 1인 창업자가 외부의 도움없이 지속적으로 높은 수준의 업무효율를 유지할 수 있게 도움이 되는 지속사용의도를 종속변수로 설정하여 본 연구를 진행하였다.

본 연구에서는 수자원 통합모델링 프레임웍을 개발하기 위하여 국내의 모델개발과 프로그램개발 환경에 대한 사용자 요구조사를 실시하였다. 요구조사의 응답자는 총 19명 이었으며, 그 응답자는 대부분 수자원의 지속적 확보기술개발 사업에 참여하고 있는 연구자를 대상으로 하였다. 사용자 요구조사 결과 국내에서는 물관련 전공자들이 모델과 프로그램의 개발을 동시에 수행하는 경우가 많았으며, 대부분 Fortran을 중심으로 다양한 프로그래밍 언어를 사용하고 있었다. 모델개발자들은 모델간의 연계에 대한 필요성은 느끼면서도 모델간의 연계에 대한 실제적인 구현도구를 찾지 못하고 있으며, 모델의 공유에 대한 인식도 낮았다. 따라서 향후 통합모델링 프레임웍의 구체적인 설계 단계에서는 모델개발자가 개발된 모델의 프로그램으로 쉽게 구현할 수 있도록 편리한 사용환경이 요구되며, 모델간의 연계를 위한 프로그램 표준화작업도 동시에 수행되어야 할 것으로 판단된다. 또한 통합모델링 프레임웍의 설계에 있어 사용자의 요구를 충분히 반영하기 위하여 사용자 요구조사를 바탕으로한 통합모델링 프레임웍 개발 가이드라인을 제시하였다.

The purpose of this research is to investigate the effects of brand extension on original brand in mobile market. TAM (Technology Acceptance Model) was used in current research to verify the 'intention to use of mobile service', and 'perceived usefulness', 'perceived ease of use', and the effect of 'extended brand's intention to use' on continuous 'intention to use in original brand' are verified in the process. According to the results, TAM was found to be appropriate to verify the intention to use of mobile service. Also by verifying the effect of decision factor, it is found that perceived ease of use have positive(+) influence on continuous intention to use of original brand. According th this finding, marketers will be able to understand better in performing strategies in mobile service environment.

In this paper, a model to evaluate the sustainability management for small and middle enterprises was suggested. Also, the if-then rules and its decision tree for pattern analysis which is obtained by fuzzy ID3 from the data of sustainability management were shown. The suggested model can be used for the evaluation tool of competition increasement of enterprises. If the enterprise can recognize that the evaluation rule can be taken advantage of the sustainability management pattern analysis using fuzzy ID3, it is expected that they can use the rule effectively for self evaluation.

This study tried to provide basic data for predicting consumers by applying the structural analysis method (SEM) to the causal relationship model that applied the technology acceptance theory for mobile home training, exercise commitment, and continuous intention. Therefore, in order to identify the strategic tools due to the current COVID-19 pandemic, the survey was conducted using the mobile program "Survey Monkey" according to the sampling plan from February 1, 2021 to May 21, 2021, and a total of 287 valid samples. people were used in the final analysis of consumers. As a result of the study, it was found that the acceptance model had a significant effect(+) on exercise commitment, and the acceptance model had a significant effect(+) on the exercise continuation intention. Finally, it was found that exercise commitment had a significant(+) effect on exercise continuity intention.

본 논문에서는 로봇이나 감시 시스템에서 주로 쓰이고 있는 배경 모델링의 정확성을 지속 시키는 방법을 제안한다. 오브젝트를 추출하려면 정확한 배경 모델이 필요하다. 정확한 배경 모델을 유지하기 위해서는 전경의 정보가 배경 모델에 반영되면 안 된다. 본 논문에서는 오브젝트의 움직임을 기반으로 한 배경 무효화 기법을 사용하여 전경이 배경 모델에 영향을 주는 것을 방지함으로써 정확한 배경 모델을 유지하는 방법을 제안한다.

The objective of this study is to analyze influential factors of sustainable consumption behavior in mobile videophone services using TAM(Technology Acceptance Model). The results of data analysis by SPSS 12.0 show that perceived usefulness, perceived easy of use, videophone service quality, concentration, and use of videophone service by acquaintances exert significant influence on continuous use for videophone services. But 'the level of neighbor's videophone possession and use, videophone charge, videophone quality, and privacy' as moderating variables haven't significant influence on extended use.

This study is based on ERIS model for start-up performance, and aims to derive the main reason for start-up sustainability centered on organizational resilience. To this end, systematic literature examination and modified Delphi method were used to investigate start-up sustainability factors based on ERIS Model focused on organizational resilience. The results showed that ERIS model-based entrepreneurial continuity factors were divided into four categories: entrepreneur, resource, industrial environment, strategy, subdivision 8 and detailed factors 54. In addition, the ERIS model-based continuity factors were structured around organizational resilience, and the continuity factors were structured according to ERIS model under five categories: leadership, culture, people, system and environment. The results of this study are as follows. First of all, the results of existing research and analysis show that the concept of successful start-up and sustainability of start-up are used in various fields. Second, it is confirmed that there are common factors of influence on start-up performance and start-up sustainability based on ERIS model. Third, Delphi method's results showed that the general characteristics of entrepreneurs, such as academic background, education level, gender, age, and business experience did not affect the sustainability of entrepreneurship. This study is significant in that it is based on ERIS model focused on organization resilience, and ERIS-R, which integrates Strategy into System and Organization resilience into R in the field of gradually expanding start-up development and support. It is expected that the results of this study will improve the sustainability of start-up that can predict, prevent, and overcome various crises at any time.
