Collaborative filtering technique is a major method of recommender systems and has been successfully implemented and serviced in real commercial online systems. However, this technique has several inherent drawbacks, such as data sparsity, cold-start, and scalability problem. Clustering-based collaborative filtering has been studied in order to handle scalability problem. This study suggests a collaborative filtering system which utilizes genetic algorithms to improve shortcomings of K-means algorithm, one of the widely used clustering techniques. Moreover, different from the previous studies that have targeted for optimized clustering results, the proposed method targets the optimization of performance of the collaborative filtering system using the clustering results, which practically can enhance the system performance.

The purpose of this study was to develop a MOOC design model that would improve the current practice of MOOC development in Korea by specifying easy-to-use course development procedures and guiding strategies. Following Richey and Klein (2007)'s conceptual model development procedure, the first step was to perform critical review of relevant literature and observe typical MOOC development processes. As a result, the initial model was developed. The second step was to conduct the expert review with five educational technology and MOOC researchers to secure the internal validity of the model. Based on the experts' suggestions, the model was revised and once again reviewed by the same experts. This process resulted in the development of the 2^nd version of model. The third step was to carry out external validation research in order to test the effectiveness, efficiency, and usability of the model. A basic model may be confirmed or corrected based on examination of its results. Consequently, the model was elaborated as the final model. In the final model, 6 procedural phases and 9 specific steps were included. The six procedural phases are: Analysis (1st Iteration), Design, Development (Course Development), Implementation, Evaluation, and Analysis (2nd Iteration), a slight variation of ADDIE model. The specific steps include: 1) Goal Setting, 2) Environment Analysis, 3) Content Design, 4) Style Design, 5) Course Development, 6) Implementation Plan, 7) Course Implementation, 8) Summative Evaluation, and 9) Need Reflection. The study concluded with suggestions for further research and application of the MOOC design model.

Methods: The materials were developed in seven steps. As a first step, the needs of pregnant and lactating women were assessed by reviewing scientific papers and existing education materials, and by interviewing a focus group. The second step was to construct main categories and the topics of information. In step 3, a draft of the contents in each topic was developed based on the scientific evidence. In step 4, a draft of card news was created by editors and designers by editing the text and embedding images in the card news. In step 5, the text, images and sequences were reviewed to improve readability by the members of the project team and nutrition experts. In step 6, parts of the text or images or the sequences of the card news were revised based on the reviews. In step 7, the card news were finalized and released online to the public. Results: A series of 26 card news for pregnant and lactating women were developed. The series covered five categories such as nutrition management, healthy food choices, food safety, favorites to avoid, nutrition management in special conditions for pregnant and lactating women. The satisfaction of 7 topics of the card news was evaluated by 140 pregnant women, and more than 70% of the women were satisfied with the materials. Conclusions: The card news format materials developed in this study are innovative nutrition education tools, and can be downloaded on the homepage of the Ministry of Food and Drug Safety. Those materials can be easily shared in social media by nutrition educators or by pregnant and lactating women to use.

Objectives: This study examined the relationship between oral health symptoms and Internet usage of Korean adolescents for the purpose of identifying problems associated with Internet usage of adolescents and of preparing measures that can raise awareness on the importance of their oral health management. Methods: The data used in this study is from the 2015 Youth Health Behavior Online Survey (YHBOS). Data from all survey participants (n=68,043) were used in the final analysis, using SPSS Ver. 22.0. General linear models were constructed to analyze the relationship between oral health symptoms and Internet usage of adolescents. Results: In the relationship between Internet usage and oral disease symptoms, those who brush less than once a day during weekdays and weekend tended to use Internet at the highest levels: 72.5%, 78.3% (p<0.001). The following variables were found to be related with spending longer time at Internet: male students (p<0.001), students in lower grades (p<0.001), students with lower performance (p<0.001), and those from families of lower economic level (p<0.001). Moreover, those who brush their teeth less than once a day and those who experienced oral disease symptoms, such as pain during chewing, throbbing and shooting pain, and bad breath in the past year spent longer time at Internet. Conclusions: The above findings show that Internet usage and demographic characteristics of the adolescents are associated with their oral health management. Therefore, guidance and interventions are needed for adolescents with problematic Internet use, while continued education is also needed to raise awareness about the importance of oral health management during adolescence.
