The purposes of this study were to examine the patterns of recalling memories in the series and look into the desires of viewers disclosed in the process. Entering the 2010s, people got to recall their memories from the 1980s and 1990s. Nostalgia and retro became cultural products. What made the series, those depict the pure love, friendship, and family affection of main characters under age in those decades, so popular among the viewers? Finding a repeating pattern in recollection of the past, dating, and family love, the investigator saw that the pattern met the needs of viewers and thus analyzed their desires inherent in the series with a focus on its "narratives" and "characters." Their unique sounds effect and music established a micro-narrative that could be divided, thus allowing viewers to own certain scenes easily, which worked to make "non-existent" memories. Secondly, the series succeeded in capturing the desire of viewers living in the age of neoliberalism to reduce their fatigue from excessive choices by setting the characters in a contrived way and thus presenting the desire of maintaining the stable middle class world with no conflicts and the passive female characters. The recollections provided by the series, in the end, fill the desire and deficiency of the present beyond a simple return to the past.

Recently, the retro content emerges one of the highest topics in the cultural content area. This retro content has been exponentially expanded through the series of and the success of the series highlights the importance of content that can cause user's emotional experience. Along the line, this research tries to know how the retro contents draw user's emotional experience beyond the role of just user's recall for the past through the Answer me 1994 syndrome. As the result of factorial analysis for the user's emotional experience, five factories were classified: the emotional experiences by music, item, sensory, story and actors exposed in the drama. Also, the five emotional experience factories influence the relations between the viewers and retro content. Specifically, the factories for the emotional experiences are statistically significant to the viewer's satisfaction. They significantly influence the viewer's trust and attachment for the retro content as well. The influence for the emotional experience factors which affect to viewer's satisfaction are music, item, sensory, story, and actors in order. The influence on the trust about the retro content are music, sensory, story, item in order. On the other hand, the emotional experience by actors are not significantly affect to the trust for the retro content. Lastly, The influence for the attachment about the retro content are music, item, actors, sensory, and story in order.

The aim of the present study is to investigate the scaling and dynamic erects on the plate cutting response. A series of cutting tests for unstiffened and longitudinally stiffened steel plate specimens in a quasi-static condition were carried out, varying the plate thickness. Based on the previous as well as the present test results, the scaling effect of Plate thickness on the cutting response is investigated. Dynamic erects are also clarified from the devious theoretical and experimental results. The Cowper-Symonds constitutive equation originally derived for mild steel is modified to consider the influence of strain-rate sensitivity on yield strength of high tensile steel.

유비쿼터스 컴퓨팅의 실현을 위해 센서 네트워크 기반의 다양한 위치인식 연구가 수행되었다. 특히 근거리 위치 인식 분야에서는 RSSI를 이용한 위치 인식에 관한 연구가 활발하였으나 RSSI는 통신 환경에 민감하여 균일한 위치 정보 결과를 획득하기 어려우며, RSSI 값을 기반으로 삼각측량 등의 위치 계산을 소프트웨어적으로 처리하기 때문에 응답 속도가 늦다는 단점이 있다. 따라서 최근 Chipcon에서는 CC243x 시리즈에 위치 계산 엔진(Location Engine)을 탑재하여 응답 속도에 대한 종전의 단점을 보완하였으나 여전히 위치 값이 고르지 못한 부분은 개선되지 않았다. 따라서 본 논문에서는 통신 환경으로 인한 위치 정보의 불균등함을 개선하고자 선형 윈도우 알고리즘을 제안한다. 선형 윈도우는 위치 정보에 대한 스무팅을 수행하며, 이를 통해 응답 속도의 저하를 최소화시키면서 위치 변화를 고르게 한다.

This paper discusses approximation modelling of discrete-time linear time-varying system(LTVS). The wavelet transform is considered as a tool for representing and approximating a LTVS. The joint time-frequency properties of wave analysis are appropriate for describing the LTVS. Simulation results is included to illustrate the potential application of the technique.

The rapid advancement of generative AI has ushered in an era where anyone can create and freely utilize personalized chatbots without the need for programming expertise. This study aimed to develop a customized chatbot based on OpenAI's GPTs for the purpose of pre-service teacher education and to analyze its educational performance in mathematics as assessed by educators guiding pre-service teachers. Responses to identical questions from a general-purpose chatbot (ChatGPT), a customized GPTs-based chatbot, and an elementary mathematics education expert were compared. The expert's responses received an average score of 4.52, while the customized GPTs-based chatbot received an average score of 3.73, indicating that the latter's performance did not reach the expert level. However, the customized GPTs-based chatbot's score, which was close to "adequate" on a 5-point scale, suggests its potential educational utility. On the other hand, the general-purpose chatbot, ChatGPT, received a lower average score of 2.86, with feedback indicating that its responses were not systematic and remained at a general level, making it less suitable for use in mathematics education. Despite the proven educational effectiveness of conventional customized chatbots, the time and cost associated with their development have been significant barriers. However, with the advent of GPTs services, anyone can now easily create chatbots tailored to both educators and learners, with responses that achieve a certain level of mathematics educational validity, thereby offering effective utilization across various aspects of mathematics education.

The purpose of this study was to investigate the small-group instruction of mathematics in elementary schools. For this, a sample of 742 teachers of elementary schools completed the survey. As a result, about 27.8% of the teachers reported using small group instruction while they worked with one group or they assigned to other groups worked alone. Only 2% of the teachers reported using small group in which students were encouraged to participated cooperatively. This study discusses the five issues about small group instruction in elementary school. The five issues were investigated in this survey. First, major teaching method in mathematics classroom and using of small group instruction were described. Second, frequency and period of small-group instruction were reported. Third, grouping method in small-group instruction was described. And Fourth, effect grouping practices of small-group instruction were described. Fifth, the model of small group instruction and assessment in small-group instruction were reported.

We investigated whether and how pre-service teachers took the realistic contexts seriously in the course of solving word problems; additionally, we investigated how pre-service teachers evaluated students' realistic and non-realistic answers to word problems. Many pre-service teachers, similar to students, solved some of the realistic problems unrealistically without taking the realistic contexts seriously. Besides, they evaluated students' non-realistic answers higher than the realistic answers. Whether the pre-service teachers could solve problems realistically or not, they did not appreciate students' realistic considerations for the reasons that those were not fitted to the intentions of the word problems, or those were evidence of the flaws of the problem. Furthermore, the analysis of premises implied in the pre-service teachers' evaluation comments showed the implicit didactic contracts about realistic word problem solving that they accepted and also anticipated students to follow. Our analysis of the pre-service teachers' conceptions of realistic word problems can help teacher educators design the teacher program to challenge and revise pre-service teachers' folk pedagogy.
