  • The purpose of this study is to search the effective teaching-learning program by considering how affect on formation of linear function using Excel. This study was based on qualitative case study. The teaching experiment using Excel executed with five 8th graders' students for second research content. Teaching experiment was performed for two classes. Collecting the data was conducted via observations and interviews with students. The data include audio and video recording of the students' work, students' worksheets and detailed field notes. The conclusions drawn from teaching experiment are as follows: First, when students explored relevancy content of function in Excel environment, formation of concept of function was facilitated by experiencing operation of algebraic formulas, tables and graphs. We could infer that formation of concept was effected by conjecture activity and iterative process of feedback through Excel environment. Second, the students explored the changes very interestingly making algebraic formulas and presenting tables and graphs. The students were familiarized with observation on algebraic formulas, graphs and tables concurrently. Also, they tried to look for general rules through inductive observation. According to this study, we noticed that exploration teaming environment using Excel could supplement paper-and-pencil environment.

  • There are many traumatic foot and ankle problems in orthopaedic fields. Though it is not life-threatening problems, a delay in accurate diagnosis and treatments can danger limb function and therefore correct diagnosis can prevent long-term complications. Achilles tendon rupture is relatively common injury for active sports people. Ultrasonography is cost-effective, irradiation -free, effective for evaluation of soft tissues and dynamic analysis. It has been growing importance in Achilles tendon rupture. Ultrasonography is a diagnostic tool in Achilles tendon rupture. Physical examination and patient history is needed to diagnose Achilles tendon without image, but it is missed up by 20% in private clinic. Discontinuity of normal fibrillar architecture seen on an ultrasonographic image is diagnostic for Achilles tendon rupture, and can be accentuated by the performance of dorsi-flexion and plantar flexion, while observing in real time. And ultrasonography is a reliable method for serial observation after surgical treatment or conservative treatment.

  • Inquiry instruction is a dynamic process that uses questioning and answering to have students actively participate in their own learning. Inquiry instruction is a teaching technique in which teachers do not provide knowledge, but help students discover knowledge by themselves. However, Inquiry instruction currently has problems of lack of connection between inquiry process and school library, lack of collaboration between the media specialist and teacher, and lack of applicable models. Information literacy is the ability to access, evaluate and use information. Information literacy process is closely related to the inquiry process. Thus, this study suggested an elaborative model in inquiry instruction using information literacy process. This research derived the skills, strategies, activities of inquiry instruction model by comparing and analyzing Lippitt's inquiry process with information literacy process(Big6 Skills, Pathways to Knowledge, I-Search, 8Ws, Inquiry Process, Inquiry in the Research Process). Based on the results, this study designed an elaborative model in inquiry instruction using information literacy process.

  • This study examined the relationship between income and the value of leisure to develop a more accurate model of the labor market without necessarily losing the primary merit of the received model. Moreover, with an improved understanding of the labor market dynamics, it can be seen that progressive era labor market legislation, which was designed to mitigate the effects of the bargaining power inequality in low wage labor markets, was in fact based on sensible economic foundations. These low-wage dynamics present an example of a positive feedback system or "vicious circle" at work in the economy. The market dynamics of the low wage sector push the wage away from the range that is consistent with a self-regulating market.

  • The purpose of this study is to propose divergence from standardization of animation acting through working on investigating gestures comprising most principal exaggeration acting elements in animation acting. For this purpose, this study utilizes animation 12 principles and Laban's effort theory. This study respectively analyzes 2D and 3D animation gesture expressions that are standards for comedy silent film and derive commonness and difference from them. In the next, this study explores the possibility of how animation can utilize acting of comedy silent film. Charles Chaplin and Buster Keaton used to be important elements referring to early animation acting, but as the recent animation technology gets advanced, they are not treated significantly any more. However, as 3D animation turns out to be chief concerns and the roles that acting, dynamics and performance play become gradually important, the necessity is on the rise that Charles Chaplin and Buster Keaton's gesture performances should more prudently be reinterpreted.

  • Media can be considered as a type of play for kids in this new media era. Researches on media content for kids have mainly focused on educational effect or specific features such as design, but a great deal of kids content is created for fun and enjoyment. This study analyzes fun factors of the most popular kids content on Youtube: Kongsuni and Friends, Carrie and Toys, and Pinkfong. The result shows that seven fun factors can be grouped into three categories; 1) Self-determination and independence are related to the media environment; 2) Sensuous vividness, empathy, and physical dynamic are related to the content; 3) Self-expression and social interaction are related to associated activities. This study extends our perspective on kids content by analyzing fun factors in the comprehensive process of media consumption.

  • This study aims to analyze the interregional trade and industrial linkage between the Incheon regional economy and the rest of the nation. An interregional input-output table developed by the Bank of Korea's Incheon branch(2007) was employed for this. The analysis of interregional trade shows that Incheon regional economy is strongly interrelated with Seoul and Gyeonggi regional economies. The Incheon's interregional relationship with other regions was analyzed in terms of output dependency rate, output inducement rate, backward linkage, and forward linkage. The results indicated that while the output of Incheon is more dependent on final demands in Seoul and Gyeonggi, changes of the final demand in Incheon cause more output in the rest of nation than that in Seoul and Gyeonggi. Also, while Incheon's backward linkage to Seoul and Gyeonggi is weaker than that to the rest of nation, Incheon's forward linkage to Seoul and Gyeonggi is stronger than that to the rest of nation.

  • Anterior cruciate ligament (ACL) injuries are treatedwith surgical reconstruction. Although ACL consists of two functional bundles, only the anteromedial bundle is surgically reconstructed, and the effect of the reconstruction of the posterolateral bundle is unknown. The purpose of this study is to investigate the role of the posterolateral bundle and the effect of double-bundle reconstruction during single-leg landing. A 3D dynamic knee with various ACL reconstructed models was created using MRI, and single-leg landing motion was simulated using in-vivo human experimental data. The results showed that the lateral shift of the tibial insertion of the anteromedial bundle and the posterolateral bundle of the ACL constrain the tibial internal rotation more efficiently than a single anteromedial bundle can. In addition, double-bundle ACL reconstruction is less sensitive to inaccuracies in the tibial tunnel placement.
