In this paper, we analyzed the misconceptions and errors incurred during factorization learning. We also examined whether online individualization classes had a positive effect on students' mathematical achievement. The experiment was conducted for 4 weeks (16 times in total) on middle school juniors in rural areas of Gyeonggi Province, where the influence of private extra education was small. In the class, the 'Google Classroom' was used as a LMS, the video lecture was uploaded to YouTube, and the teacher interacted with the students through "Zoom" and "Facetalk". In the online class situation, students' assignments and test answers were checked in real time through 'Google Classroom', and immediate feedback was provided to the experimental class group's students. However, for the control group students, feedback was provided only to those who desired. A total of 7 achievement evaluations were conducted in the order of pre-test, formative evaluation (5 times), and post-test to confirm the change in students' ability improvement and achievement. Through the formative evaluation analysis, it was possible to grasp the types of errors and misconceptions that occured during the factorization process. Students' errors were divided into four types: theorem or definition distortion error, functional errors such as calculation, operation, and manipulation, errors that do not verify the solution, and no response. As a result of ANCOVA, the two groups did not show any difference from the 1st to 4th formative assessment. However, the 5th formative assessment and post-test showed statistically significant differences, confirming that online individualization classes contributed to improvemed achievement.

This article analyzes individualization of family policies and gender division of unpaid work in Germany, Netherlands and South Korea. Measured in terms of women's employment promotion, the individualization at the policy level was greater in Korea than both Germany and Netherlands. However, married women's share of unpaid work was substantially larger in Korea than Germany and Netherlands. The strong unequal divison of unpaid work was also the case among working married women. Regression analysis showed that share of unpaid work in Korea was related to relative income in all three countries. But while gender ideology was positively related to married women's share of unpaid work in Germany and Netherlands, the relationship was not found in Korea. Gender of respondent was also an explanatory factor for all three countries. The influence of married women's relative income and gender ideology on share of unpaid work was similar to or larger than the effect of gender of respondents in Germany and Netherlands. By contrast, it was gender of respondent that mattered most for married women's share of unpaid work in Korea. Among working married women, we found that both relative income and gender ideology were related to differences in share of unpaid work in Germany and Netherlands which was either similar to or larger than the effect of gender of respondent. However, we found that gender of respondent mattered most in Korea.

Recently, 3-D audio technologies are commonly implemented through headphones. A major problem of the headphone-based 3-D audio is in-the-head localization, which occurs due to the inaccurate Head-Related Transfer Function (HRTF). Since the individual measurements of HRTFs are impractical, there have been several researches for HRTF customization. In this paper, an efficient method of customizing HRTFs for the sound externalization is proposed. Firstly, it is determined which part will be customized in HRTF through psychoacoustical experiments. Then, the method controlling spectral notches and envelopes to provide individual localization cues are described. Since the proposed method is based on a critical-band rate, the structure is much simpler than that of previous studies, but still effective. The performance was evaluated through a series of subjective tests, and the results confirmed that the customized HRTF using proposed method could replace the measured individual HRTF successfully.

This study researched the changes in everyday wear in China since the mid-20th century. The study was conducted by interviewing 13 Chinese persons who were familiar with the public awareness and donning practices of the Chinese from 1949 to now, and the results were analyzed through categorical analysis and subject analysis. First of all, due to the influences of Zhongshan-zhuang, Liening-zhuang and Bulaji, political characteristics were represented the most during the reconstruction time, and during this time, Jieyueling also became famous. Second, during the period of the Cultural Revolution, the government used many mechanisms to control people's thought, so Junfu/Junbianfu and sailor shirt were the most common clothing. Third, information from the West began to enter the Chinese market and it started to influence and change the Chinese thinking. Suit, bat wing sleeves, colorful skirt, flares and jeans became more and more popular in the reform and open times. Fourth, during the personality expression time, people not only copied fashion icons' styles, but also created new styles like sexy, cute, ethnic, K-pop, street, and DIY style, in order to show their personality. Finally, during these 60 years, the changes of Chinese everyday wear were characterized by de-politicization, ready-made, diversification and individualization.

One of the potential advantages of computer-based instruction is individualization of instruction. However, this goal has not been fully realized in practice, due largely to limitations of natural language understanding and to combinatorial explosion. It is nonetheless possible to develop CAT(Computer- based Adaptive Testing) Programs which can adapt to students, depending on their performance, by adjusting the length of computer-based tests. The number of questions can be significantly reduced for many individuals, while mastery and nonmastery decisions remain highly accurate. In this paper, We design and implement a Diagnosis System using SPRT(Sequential Probability Ratio Testing). This system supports multimedia object, client/server environment, indvidual feedback, multi-SPRT and maintain student model for individualization of instruction. besides, this system measures coefficient alpha of each problem.

Purpose: An omnichannel strategy creates a consistent brand image and customer experience across all channels, making it easier for customers to interact with a business and share information. This research aimed to investigated the relationship between consumers' information-sharing intention and their omnichannel experiences. Research design, data, and methodology: Through an online survey conducted in Vietnam, the study obtained 915 responses. The study used Partial Least Square Structural Equation Modeling (PLS-SEM) to analyze research data and confirm proposed research hypotheses. Results: Research results indicated that information-sharing intention is affected by both online and offline customer experience, and at the same time, the study also confirmed that omnichannel's three characteristics (integration, individualization, interaction) positively impact on customer experience. Conclusions: From the research result, businesses may boost consumer trust and loyalty with the help of an omnichannel approach, which in turn increases customers' propensity to provide personally identifying information to the firm. One way to do this is to facilitate information exchange by delivering customized and relevant offers. Furthermore, companies show consumers the benefit of providing their data by utilizing it to enhance the customer experience.

Objectives: This study evaluated the bond strength of various fiberglass post cementation techniques using different resin-based composites. Materials and Methods: The roots from a total of 100 bovine incisors were randomly assigned to 5 treatment groups: G1, post + Scotchbond Multi-Purpose (SBMP) + RelyX ARC luting agent; G2, relined post (Filtek Z250) + SBMP + RelyX ARC; G3, individualized post (Filtek Z250) + SBMP; G4, individualized post (Filtek Bulk-Fill) + SBMP; G5, individualized post (Filtek Bulk-Fill Flow) + SBMP. The samples were subjected to the push-out (n = 10) and pull-out (n = 10) bond strength tests. Data from the push-out bond strength test were analyzed using 2-way analysis of variance (ANOVA) with the Bonferroni post hoc test, and data from the pull-out bond strength test were analyzed using 1-way ANOVA. Results: The data for push-out bond strength presented higher values for G2 and G5, mainly in the cervical and middle thirds, and the data from the apical third showed a lower mean push-out bond strength in all groups. No significant difference was noted for pull-out bond strength among all groups. The most frequent failure modes observed were adhesive failure between dentine and resin and mixed failure. Conclusions: Fiberglass post cementation using restorative and flowable bulk-fill composites with the individualization technique may be a promising alternative to existing methods of post cementation.

This thesis suggested that the 'customized' marketing would be a new strategy in terms of a marketing in the digital media age under the circumstances where a form of marketing was evolving in accordance with the convergence of digital media. Because of the media environment due to an 'individualization', the strategy would meet an individual demand of a consumer in a rapidly changing environment. The best marketing to capture a 'customer's heart' is not a brand that first entered the market, but the one that is first settled in a customer's heart. If a differentiated interactive marketing strategy is equipped, it is possible to capture a completely new market space ad create a profit over several years. In the aspect of an effect of a digital marketing, first, a concept relating to an interaction between a consumer and a producer is important. Secondly, the important one is an empathy marketing which is an emotional marketing through a brand image beyond a product. Thirdly, the author studied an orally transmitted marketing effect through digital media.
