In order to help the understanding of web novel users, this study was intended to quantitatively verify the user's behavioral types according to the characteristics of web novels. For this purpose, the direction of the study proceeded as follows. First, the motives of web novel users were investigated by referring to the motives of other digital content users. In addition, specific behavioral types of users were also collected. As a result, the motivation for using web novels was found to be 'interpersonal relationships and information acquisition with others', 'leisure activities', and 'escape from reality/relieve tension'. After that, the groups were classified as to whether there was a difference between groups according to the motives of use. As a result, the 'hobbies' type, a group with a particularly high motivation for using leisure activities, the 'stress relief' type, a group with very high escapism and tension relief characteristics, and a group with high interpersonal relationships and information acquisition with others The 'communication' type was classified as a 'multipurpose' type with high overall motivation characteristics. Then, in order to find out the specific characteristics between the types, personas were constructed based on the different behavior type data. Through this, the theoretical contribution of this study is meaningful in that it revealed the motives of web novel users. As a practical contribution, the persona was formed by combining the users' motives and behavioral patterns and visualized to be close to the actual representative users. These results are expected to help improve the web novel service by providing useful indicators for actual writers, platform managers, and users.

As Internet grows, many web sites have been built, therefore much information has been registered. Because the web sites have more information, it is more difficult that the user can find the information wanted. Therefore, to get information that user wants easily, the full-text engine may be embedded to the web site. This paper is about developing the help conversational agent for a user to find the information that he wants through conversation with agent. The proposed method is based on the pattern matching of artificial intelligence, not natural language processing. If a user inputs any sentence, the help conversational agent responds to the sentence through preprocessing and pattern matching with knowledge. The knowledge is built with the XML format. With the approximate pattern matching, the agent picks up the appropriate response with some degree of similarities. At the experiment, some different sentences with the same meaning have been entered, then the agent recognized them as the same pattern, and it made a correct answer.

The study examined differences between perceptions of AI speakers and intention to continuous use of AI speakers according to usage function. We divided usage patterns into single- and multi-function orientations based on the usage by different functions of audio content (music, news, and search), and analyzed the differences between perceptions of using AI speakers and the intention to continuous use. 335 men and women who had experience using AI speakers participated in an online survey. Results are as follows. First, men used AI speakers mainly for acquiring news, and the extent to which 20s and 40s acquire news was different. Second, perceptions of usefulness and ease of use were found to be higher in the multi-functional group(music-news-search). Last, regarding the intention to continuous use of AI speakers, the multi-functional group was highest, and users focusing on music listening were relatively higher than users for other functions. The findings of the study are expected to be used as foundational data for expanding the use of AI speakers and developing strategies for service provision in each AI speaker brand.

The demand increasing of optical applications like as display devices derives interest for fabrication process. The product s development is apt to fabricate numerous thin and wide surfaces with micro pattern. Naturally that needs injection molding fabrication for the mass production. In existing manufacturing, the product quality is controlled by input fabrication condition from the outside. That can be called as a try and error method and not fundamentally solve the troubles; imperfect replication, war page, short shot, etc. To understand the cause and bring a solution, it is needed that check of changing in the cavity. This study can catch them. Data acquisition system about temperature and pressure distribution is settled and can get some data. From this research, other studies related with DAQ in cavity can start on the easier step.

The purpose of this research is to suggest the method of code analysis for evaluating learners' projects in computational thinking(CT) education. Recently, block programming tools are applied to K-12 SW education, this study considered the assessment method for evaluating students' levels and learning about CT concepts through analyzing codes of the Scratch projects that students created. As a result from the analysis of 45 projects of novices, it showed the bad coding patterns of novices and verified that it is possible to evaluate students' learning about CT concepts through the analysis of their codes. The higher learner's level, the greater scores of logical thinking, synchronization, flow control, and data representation. This result is able to apply to student assessment of CT concepts in K-12 SW education.

새로운 지식과 패턴을 발견하고자 하는 데이터 마이닝 알고리즘들은 큰 수의 규칙들을 생성하는 문제점을 가지고 있다. 최근 들어 이러한 문제를 해결하기 위한 방법으로 다양한 유용성(Interestingness) 연구들이 데이터 마이닝의 후처리 단계에서 진행되고 있다. 그러나 이러한 접근방법들 역시 지식을 습득하기 위한 과정에서 병목현상을 보여줌으로써 수많은 상식수준의 규칙을 정제하지 못하고 있다. 본 연구에서는 이러한 문제점을 해결하기 위한 방안으로 상식을 기반으로 하는 Common-Sense 척도를 정의하고 구현한다. 규칙이 얼마나 상식에 가까운지를 시맨틱 차원교체 기법을 이용한 유사도 분석을 통해 측정한다.

스마트폰의 등장 이후, 사람들의 미디어 이용 패턴는 급격히 변했다. 유비쿼터스 가속화로 언제, 어디서든 미디어를 사용할 수 있게 됐기 때문이다. 홈페이지, 블로그를 비롯해 페이스북과 트위터 등 소셜미디어의 등장으로 소비자는 단순히 정보를 습득하는 'Push형 이용'에서, 자신의 의사를 표현하는 '참여형 이용'으로 변하고 있다. 이런 변화 속에서 브랜드들은 소셜미디어를 통해 소비자들과 적극적인 관계 맺기에 나서고 있다. '이것은 좋은 브랜드 또는 제품입니다'라고 단순하게 말하는 데 그치는 것이 아닌, '좋은 브랜드 또는 제품'임을 직접적으로 보여주며 소비자와 관계자를 맺는 시대가 도래한 것이다. 인쇄도 마찬가지다. 이제는 인쇄도 B2B가 아닌 B2C 즉 소비자와 직접 대면하는 업종으로 변하고 있다. 소비자들과의 소통 여부가 인쇄산업 활성화에도 반드시 필요한 요소가 되고 있다.

Recently, types of mobile services are ever-growing with technological advances, such as CDMA 2000, 256 Color LCD, 16 channel sound chip set and easy internet access. However, manual system that is supposed to support users for finding features and functions doesn't help users most of the cases since users are moving. Therefore, mobile sonics needs new concept for manual system that can support users while they are in use In this research report, new concept for interactive manual system is suggested. Then a guideline for interactive manual system is developed as a result from three empirical studies. First, ten information visualization methods used for describing functions are positioned on user's perception map. Secondly, user behavior pattern of getting required information from written manual was analyzed. Finally, visual cue system was selected as one of options for developing interactive manual system and a guideline was developed based on these research results.

In the advanced information age, learning is an activity in which learners access information resources through computers and Internet to acquire and evaluate information on their own. The emergence of an online learning platform based on the fourth industrial revolution technology is developing into an environment in which elementary and secondary learners learn and study based on constructivism learning theory. In the online learning environment, the researches on the information retrieval ability of the elementary and secondary learners and the self-directed learning ability were found to be highly related. However, it is necessary to analyze the relation between information retrieval ability and self-directed learning ability through a cross-sectional study that is limited to specific curriculum and contents and expands the longitudinal research. In this study, the panel data of the Seoul Education Longitudinal Study collected over 8 years are used to find the difference in self-directed learning ability according to the longitudinal pattern of information retrieval ability and frequency.
