The purpose of this study is to investigate the factors that influence the intention to continuously use the RPA program used in the financial industry for those working in the financial industry. In particular, the purpose of this study is to understand the will to accept and the perception of acceptance conflict by considering the characteristics of individuals in the relationship between work and information technology. As a result of the study, it can be confirmed that the RPA system based on intelligent process automation including artificial intelligence should be further strengthened in the transformation of a digitalized enterprise rather than the RPA based on simple task automation that is currently most used. In general, the phenomenon of cognitive dissonance was prominent for the adoption of new technology, but the phenomenon of cognitive dissonance did not appear for the continued use of RPA in the financial industry. Able to know. In the future in the financial industry, it is thought that the change in the labor organization will be accelerated as the suitability of repetitive tasks and technologies is increased.

The major functions of the digital textbooks that have been developed recently were focused on electronic whiteboard, learning tools, multimedia. But supporting contents retrieval was not included yet. This study is aimed to develop an elementary digital textbook that supports retrieval function. We surveyed elementary teachers about the requirements for search function and a digital textbook was designed and implemented based on the result of the survey. The distinctive feature of the developed digital textbook, which is written in XML, is that it is enabled to search the units of meaningful phrases. The survey which was carried out after using the new digital textbook showed that more than 90% of the teachers think that it is quite useful in class and they would like to use this textbook in their class. If a retrieval function can be added to the digital textbook which is going to be supplied to elementary schools, it will be a lot helpful for teaching and learning procedure.

We designed optical systems for a mobile phone camera using a spherical SELFOC lens and an aspherical plastic lens. Since the radial index distribution gives an additional design parameter for optical design, an aspheric lens could be replaced by a spherical lens. The imaging performances of the design were compared with conventional 2P design composed of two aspherical plastic lenses. In the first stage of study, we designed 1GRIN 1P lenses by using commercially available SELFOC materials. But, the conventional 2P lenses had better performance than the 1GRIN 1P lenses. In the 1GRIN 1P designs, the performance depends on index variation of GRIN material, the larger variation gives the better performance. Hence, we tried to design by using fictitious GRIN materials which have large index variation. We found if the index variation could be increased to about 3 times that of currently available SELFOC materials, the 1GRIN 1P lens will have equivalent or better performance than the conventional 2P design.

This article aims at a discourse analysis on the selected 1970s Myungrang Manwhas, in the cases of Ggubungi, Doggaebi Gamtu, Yochul Balmyungwang. For the analysis, the history, pre-censorship, and distribution structure of Myungrang Manwha are referenced, as well as the considerable changes and developments on the definition of 'myungrang' since the 1920s. In employing Foucauldian discourse analysis to the texts, the selected Myungrang Manwhas are analyzed as discursive formation, which emerged within the social relations of the era; the characters' dialogues are analyzed as statement. The analysis examines the discourses that the texts disseminated, and the social context of the utterance. It is demonstrated that the Myungrang Manwhas are forms of representation, which implies 'the contested acquisition on capital and power', 'the emphasis on nationalist aspects', and 'the interpellation and discipline of subject active' of the time. Moreover, it is revealed that the forms of control, such as pre-censorship, were the articulation of the will to power, which drove the discoursive formation to function as an apparatus that meticulously constituted the ruling ideology. In conclusion, the Myungrang Manwhas are rather texts that encompasses political and social context of the era than a mere comic relief.

At the stage of conceptual design of a helicopter, it is a general way using low fidelity analysis methods because of a large number of design calculations and trade-off studies. Determination of empirical parameters used in analysis codes for more practical design, depends on an user's design experiences, which effects on the accuracy and the fidelity of conceptual design results. Thus, more precise and logical method should be required to determine the empirical parameters used in the conceptual design of a helicopter. The present method is to be used not only in verifying the empirical parameters generated by design requirements, but also regenerate them if they contain any errors. Empirical parameters produced by present method were used to design a helicopter with a payload objective and performance constraints of an operating helicopter. As a result, weights and geometries of designed helicopter matched the target value within 5% significance level, proving that the suggested parameter generating method can be useful in the conceptual design of a helicopter.

The purpose of this study is to analyze the acceptance about new seed of Chinese cabbage and to analyze the factors affecting continuous use. Research model was derived based on the Technology Acceptance Model(TAM), the analysis was performed using Partial Least Squares(PLS). The factors significantly affecting the use of new seed of Chinese cabbage are innovativeness and seed promotion in antecedent variables and perceived usefulness in parameter variables, which have strong positive relationship among them. Therefore, efforts such as development and diffusion of high quality seed and securing a market for Chinese cabbage of new seed are necessary for improving perceived usefulness. Since these efforts including seed promotion can enhance the farmers' acceptance of new seed and reduce the risk that farmers would face in introducing new seed, these can also be very helpful in enhancing the farmers' innovativeness.

The aim of this study is verifying the effects of chatbot's error types and structures of error message on attitude, behavior intention towards the chatbot and perceived usability of the chatbot. The error types of chatbot are divided into 'experience' error and 'agency' error, which set different expectancy level, according to mind perception theory. The structures of error message were either unstructured condition composed of error specification only or structured condition composed of apology, explanation and willingness of improvement. It was found that score of perceived usability was higher in experience error condition than agency error condition. Also, all three scores of dependent variables were higher in structured error message condition than unstructured error message condition. Furthermore, expectation gap of experience didn't predict the dependent variables but expectation gap of agency predicted all three dependent variables. Finally, the tendency of interaction effect between the error type and the structure of the error message on expectation gap of agency was observed. This study confirmed the mitigating effect of structured error messages and the possibility that these effects may vary by the type of error. The result is expected to be applicable to design of error coping strategies that enhance user experience.

Most previous research on safer sex and condom use has been mainly focused on individual's dispositional factors such as attitudes, perceived control, intention, and etc. However, a few researchers recently started to propose that condom use is not a matter of individual behavioral decision but a product of serious interactive negotiation processes and condom negotiation would be the proximal key-determinant of condom use behaviors. The present research categorized condom-negotiation strategies and preferences of Korean college students and examined relationship between the strategies and other sex-related concepts. 186 participants' strategies on a free-response questions of condom negotiation revealed 7 types of persuasion strategies for condom use; Pregnancy risk, responsibility, care for partner, withholding sex, sexual disease, direct request, and sexual satisfaction (in order of preference). 6 types of persuasion strategies for condom avoid were abstracted: Pregnancy free, Sexual satisfaction, responsibility, direct request, unfaith toward condom, and withholding sex (in order of preference). The effects of gender, sexual experience, and culture were found and discussed in their implications for sexual education,
