This study systematically examined the influence of preservice teachers' self-efficacy and AI anxiety, on the intention to use AI programs 'knock-knock! mathematics expedition' in mathematics lessons based on a technology acceptance model. The research model was established with variables including self-efficacy, AI anxiety, perceived ease of use, perceived usefulness, and intention of use from 254 pre-service teachers. The structural relationships and direct and indirect effects between these variables were examined through structural equation modeling. The results indicated that self-efficacy significantly affected perceived ease of use, perceived usefulness, and intention to use. In contrast, AI anxiety did not significantly influence perceived ease of use and perceived usefulness. Perceived ease of use significantly affected perceived usefulness and intention to use and perceived usefulness significantly affected intention to use. The findings offer insights and strategies for encouraging the use of 'knock-knock! mathematics expedition' by preservice teachers in mathematics lessons.

This study aims to identify the current usage patterns of VR content among users and their demands for VR content services in libraries. An online survey was conducted, receiving responses from 229 individuals with experience using VR content. The Technology Acceptance Model (TAM) analysis revealed a good model fit, indicating that users' perceptions of the usefulness and ease of use of VR content are significantly related to their satisfaction and intention to reuse VR content. These findings suggest that to enhance satisfaction with VR content services in libraries, it is essential to improve user convenience and create an immersive environment. Additionally, respondents indicated that VR content services could increase library user satisfaction and the intention to revisit the library. The most preferred VR content themes were games (action, strategy, etc.), travel, and space/ocean, in that order. While the overall feedback on providing VR content services in libraries was positive and filled with anticipation, some respondents expressed concerns about the potential lack of utility and the possibility of poor equipment management.

Unlike existing social platforms that seek openness, an audio-based social platform is characterized by its limitations. This study uses the Value-Based Acceptance Model(VAM) to analyze the role that such limitations play in the user's acceptance of audio-based social media. In this study, restrictive properties are defined as access-limitation, communication-limitation, and content-limitation. This study aims to analyze the effect of each variable on the perceived value and usage of audio-based social media. The hypothesis test was conducted based on the survey responses total of 207 users and potential users. The results was analyzed that three limiting variables affect perceived benefit factors, usefulness and playfulness, and the user's acceptance intention. This study is significant in that it presents a model based on the VAM and provides guidance for new forms of social media growth.

제 학문적 화두는 한국 전통과학의 전개과정을 체계화할 관점을 세우는 것이었습니다. 우리나라는 예부터 전세계의 과학지식과 기술을 받아들여 왔지만 언제나 한국적 모델로 재창조해 왔습니다. 이 같은 ‘수용과 창조의 역사’가 바로 우리 과학사입니다.

The purpose of this study was to analyze the college students' acceptance of PatentNOW, which was developed for effective proceeding of patent application education program. Results of this research as follow. First, perceived ease of use positively influenced perceived usefulness. Second, perceived usefulness and perceived ease of use positively influenced attitude toward using and attitude toward using also positively influenced behavioral intention to use. Third, the level of prior knowledge about the patent system and experience of patent application possessed by the users of PatentNOW had a negative effect on the relationship between perceived ease of use and attitude toward using. These results suggested that the teaching method of utilizing PatentNOW should be differentiated according to the level of prior knowledge of the students in order to improve the quality of patent application education.

This research aims to examine the efficiency and effectiveness of the governmental policies promoting IPTV by verifying their influences on the adoption empirically. The government unveiled several policies including creating demands in public sectors, developing diverse public contents, subsidizing the production of converged contents, easing the regulations to promote IPTV industry. While a lot of previous literature has already proved that a system quality, a content quality, and a perceived price have influences on the adoption of IPTV, the effects of governmental policies are not well understood despite of their contributions to the adoption. Rather, most of existing research on governmental policies in the context of technology adoption have focused on regulatory frameworks. The results of the study show that governmental policies have influences on consumers' perceived system quality and content quality. It is also found that perceived system quality, content quality and perceived price have influences on adoption intention. This study can contribute to the field in a way that it proves the important roles of governmental policies in the diffusion of new technologies including IPTV.

OXC는 정적인 점대점 광전송망에서 동적인 그물형 전광통신망으로 진화하기 위하여 망에 도입되어야 할 새로운 광네트워크 장비이다. OXC는 링크 단위의 스위칭을 하는 FXC 파장 단위의 스위칭 기능이 있으나 파장 변환 기능이 없는 WSXC, 그리고 파장 변환 기능이 있는 WIXC로 구분할 수 있으며, 이들간의 hybrid 도 가능하다. OXC 하드웨어의 중심을 이루는 것은 광스위치이다. MEMS 기술, 열광학 효과를 이용한 광도파로 기술, 전반사를 이용하는 bubble 스위치 기술 등을 사용하여 개발이 진행되고 있다. 현재까지는 이 중 3D MEMS 기술이 대용량 스위치를 구성할 가능성이 있는 기술로 받아들여지고 있다. OXC를 구성하는데 있어서 또 다른 핵심적인 기술에는 파장변환 기술이 있다. 광전 파장변환기와 전광 파장변환기 방식이 현재 연구되고 있으며 초기에는 광전변환 방식이 OXC 시스템에 적용될 가능성이 높다. 전광 파장변환기의 시스템 적용을 위해서는 좀 더 많은 연구가 필요할 것으로 보인다. OXC를 사용하는 전광통신망에서 광스위치 기술 이상으로 많은 논란이 되는 것은 망의 운용 문제이다. 현재 가장 많이 언급되는 모델은 오버레이 모델과 피어 모델이다. 오버레이 모델은 클라이언트/서버 개념에 기반한 모델인 반면 피어 모델은 광 네트워크 장비와 기존 장비를 대등한 관계로 정의한 모델이다. 각각의 모델에 대해서는 표준화 단체에 따라 약간씩 다른 입장을 취하고 있지만 상호 간에 수용 또는 타협할 점이 많다고 볼 수 있다. OXC를 포함하는 전광 통신망을 운용할 때에는 동적 연결 설정 및 해제를 위한 새로운 신호 방식이 필요하다. 이를 위하여 ITU-T 및 OIF에서 UNI와 NNI등의 인터페이스와 여기에 사용되는 신호 방식을 논의하고 있다. 그 외에도 전광 통신망 운용에 필요한 라우팅 및 파장할당 방법과 OXC를 이용한 그물형 망에서의 보호 및 복구에 대한 연구도 활발히 진행되고 있다.

Airlines have been introducing self check-in kiosks to reduce check-in time and improve operational efficacy to increase business revenue. The domestic airlines have actively provided kiosks at airports which are expected to reduce their operating costs and enrich their passengers' travel convenience. Based on the above background, the study investigates the factors influencing intention to use the self check-in kiosks by employing the Extended Technology Acceptance Model (ETAM). The study, therefore, designed a research model by reviewing theories and studies on the relationship among information quality, innovativeness, perceived ease of use, perceived usefulness, and intention to use the kiosks. The structural equation model revealed the following. Information quality and innovativeness had a significantly positive influence on perceived ease of use and perceived usefulness; furthermore, perceived ease of use had a significantly positive influence on perceived usefulness. In addition, both perceived ease of use and perceived usefulness had a significantly positive influence on intention to use. The results indicate that the airlines should constantly develop user-friendly contents and design of the self check-in kiosks.

This monograph was probed effectively by using practical methods in a subjectivity study that was accessible in depth, departing from bygone behavior of functional quantity analysis of awareness and the opinions of young people about the general (public) model of TV advertising. The perception patterns resolved in this study sorted out four types in a Q-methodology. The result is divided as follows: 1 [(N=7): Advertising Consensus Type], 2 [(N=7): Advertising Negative Type], 3 [(N=5): Advertising Purchasing Reduction Type], and 4 [(N=1): Advertising Persuasion Orientation Type]. As such, we found very different types all over. Finally, this study reviews subjective acceptance as to the type of model reception with regard to general TV advertising, offering a developmental suggestion on the issue, and an agenda about it.
