Comparison challenge approach is proposed as a form of challenger-activated. just-in-time Internet advertising. To develop a framework for a comparison challenge, we propose a theory of comparison value. A comparison is regarded valuable if a comparison opportunity is available and if the comparison is relevant and informative, has an appropriate level of detail, and is advantageous and trustworthy. Based on this theory, the CompareMe and CompareThem strategies are devised, and comparable objects are classified in terms of price and performance dominance as well as the scope of proximity. The idea is demonstrated with a comparison of PCs from five leading manufacturers. To assist in the planning of the comparison challenge, a mathematical programming model was formulated to maximize the value of comparison under the constraints of the comparison opportunity and budget. The model is applied to eight scenarios in terms of the range of comparing objects. The models under various scenarios are tested and contrasted with the real-world example of PCs. We found the ad effect of comparison challenge to be substantially better than banners (4.75 times) and similarity-based comparisons (2.77 times), providing customers with better performance and reduced prices.

Electrical impedance tomography is an imaging technique to reconstruct the internal conductivity distribution based on applied small currents and measured voltages through an array of electrodes attached on the boundary of a domain of interest. In this paper, an analytical solver with complete electrode model is derived and the analytical voltage data are calculated. Moreover, the voltage data are also computed with existing numerical solvers such as finite element method and boundary element method. The forward solutions using homogeneous and inhomogeneous conditions are compared with phantom experiments through the root mean square errors.

This study is aimed at finding some drawbacks of current elementary mathematics textbooks and to give suggestions for ongoing new textbooks according to 2009 revised curriculums, by comparing and analyzing Korean textbooks and chinese textbooks of People's Education Press. The areas are confined to number concepts, addition and subtraction for comparative analyzing. The results are followings: Korea textbooks have more verbal expressions, designated instructive activities for students to do, similar algorithm applied for enlarging mathematical concepts, bigger number concepts and number usage of operations, and monotonous number sense activities. Therefore Korean textbooks, compared to China's, is more weaker in areas such as encouraging student's interest, in challenging mathematics, and in forming fundamental mathematical concept.

This study sets a hypothesis on that the use of input control devices, which are similar to what we experience in real life, to control activities in games increases players' immersion rate, and compares general input control devices with dedicated input control devices in order to show appropriate results. Accordingly the process of the study is derived and the hypothesis is substantiated by understanding the relationship between game controlling activities and immersion rate. Overall satisfaction survey result on the use of dedicated devices shows that most players responded that they felt immersed enough in games when used dedicated devices and were highly satisfied. The use of the dedicated devices had positive impact on the increase of immersion rate in general. In order to increase immersion rate with controlling activities in games, the use of input control devices that are easy to handle and enable precise control is required, which shows that it will bring more fun and more increased immersion rate.

External environment of enterprises are rapidly changing brought about mainly by global competition, cost and profitability pressures, and emerging new technology. In particular, frequent change of customer requirements is a tough challenge to manufacturing company. To cope with these challenges, a production planning and scheduling (PP&S) function might be established to provide accountability for both customer service and operational efficiency. PP&S deals with short-term decision making in the production process of whole supply chain. The task of PP&S is to seek a balance between customer orders and limited resources. At present, many PP&S software solutions have been utilized in many enterprises to generate a realistic production plan and schedule efficiently. The aim of this paper is to analyze the PP&S functionalities and its system architecture from the perspective of SCM (Supply Chain Management), and propose the PP&S solution classification framework to facilitate the comparison among various solutions.

The Korean government is building a virtuous cycle of startups and venture businesses for a dynamic, innovative economy. This ecosystem is made possible when a social environment that embraces tolerance and turn business failure into re-startups and challenging venture startups by outstanding entrepreneurs are present. Due to the government's efforts to promote start-ups and venture businesses, their number has been increasing annually, but the efforts to create a social environment for re-startups and establish a relevant institution have recently started. This study is aimed at providing policy direction for re-startups by getting policy implications after identifying the current status of domestic failed businessmen' re-startups based on previous researches on failed businessmen. This study also reviewed advanced nations' cases and made international comparison of re-startup policies. Before the startup culture that recognizes failure as the stage for success is formed as in the U.S., it is necessary to create a legal basis for continuously pushing for the rechallenge policy of EU's Small Business Act and establish and operate the private sector-driven revitalization council of SMEs in Japan. It is also necessary to consider the guarantee of failed businessmen' livelihood. If additional research and government policies are added to the conclusions made on the policy implications, this research will provide an in-depth insight for revitalizing domestic re-startup.

This study was to analyze the students' engagement in regular curriculum and extra-curriculum and its effects on learning outcomes in higher education. Students' engagement was analysed by high order learning, reflective and integrative learning, learning strategies, collaborative learning, discussions with diverse others, and high impact activities. To achieve the purpose of this study, 392 students joined in K-NSSE were participated. To analyze the datum, frequency analysis, ANOVA, correlation analysis, and regression analysis were performed using IBM SPSS 25.0 program. The following results were obtained. First, students' engagement was generally very low, especially in high impact activities which has an effect on the students' achievement. And compared to the students' engagement in the college of humanity and social science, the students' engagement in engineering college were very low. Learning outcomes were influenced by the high impact activities, high-order learning, and discussions with diverse others. So to reinforce students' engagement in learning process, this study proposed a curriculum-extracurriculum integrated system. And to improvement students' engagement, teaching and learning support programs including high impact activities. high order learning, and discussions with diverse others were proposed to be developed and operated.

In order to improve performances of submicrometer-sized Si negative electrode which shows larger volumetric change than nano-sized Si, composite binders are introduced by blending between poly(phenanthrenequinone) (PPQ) conductive polymer binder and poly(acrylic acid) (PAA) having good adhesion strength due to its carboxyl functional group. Blending between PPQ and PAA shows an effect that the adhesion strength of the Si electrode with the composite conductive binder is greatly improved after blending and this makes its better stable cycle performance. Blending ratios between PPQ and PAA in this work are 2:1, 1:1, 1:2 (by weight) and the best capacity retention at 50th cycle is observed in the electrode with the blending ratio 2:1 (named QA21). This is because that PPQ plays a role of conductive carbon among the Si particles or between Si particles and Cu current collector and PAA binds effectively the particles and the current collector. According to this synergetic effect, the internal resistance of the Si electrode with the blending ratio 2:1 is the smallest value. In addition, the Si electrode with PPQ-PAA composite binder shows the better stable cycle performance than the electrode with conventional super-P conductive carbon (20 wt.%).

Park Wudang formally registered Daesoon Jinrihoe in 1969. While it shares ideas and history with other Jeungsanist groups, this paper argues that its organizational profile is unique. The two major institutional structures, the bonbu (headquarters) and the bangmyeon (branch) have together created space for the rapid development of this Korean new religion. The bonbu is a centralized hierarchy, while the bangmyeon exhibits the strong loyalty and cohesiveness of the clan. Running throughout both structural forms is the lineage concept, which is conceived here as an articulating paradigm able to operate in different organizational forms. This finely-balanced institutional structure makes a major contribution to Daesoon Jinrihoe's ability to fulfill its religious mission. The first side of this balance is the headquarters, which includes the core organization based in Yeoju as well as some outside temples and training centers. All of these were established under the direction of the Lord of Principle, the Dojeon, Park Wudang. Park Wudang also fixed the Dao Constitution, the Doheon, which serves as a blueprint for governance. From the Central Council to the various institutions for propagation, guidance, and auditing, current management practices conform closely to Park Wudang's organization vision. The second aspect of Daesoon Jinrihoe's organization is the branch structure. The larger branches, such as Yeongwol and Geumreung, are complex organizations in their own rights. The paper concludes by characterizing the two major axes of headquarters and branch as organizational types. Using Robert Quinn and Kim Cameron's institutional typology, the paper concludes that the bonbu is a classic centralized hierarchy with its focus on efficiency. The bangmyeon, in contrast, with its high level of group identity and spirit, comes approximates the clan institutional structure.

This study aimed to analyze the personality of 141 pre-service early childhood teachers who will be in charge of the quality of education in the early childhood curriculum and to verify the differences in the career resilience according to the personality types. Career resilirnce, which measures the ability to cope with various problems and create ideas according to the work environment, was judged to be a very important factor for teacher-child interaction and successful operation of the early childhood curriculum. The results of the study showed that, among personality types, in the case of extraversion and conscientiousness, groups with average scores or higher scored higher in creativity, flexibility, challenging spirit, and future orientation than the groups below. In the case of the openness personality, higher scores in creativity, flexibility and challenging spirit, and in the case of the agreeable personality, the group showed significantly higher scores in flexibility and future orientation. In the case of the neurotic personality, on the contrary, the group with below average score received higher scores in flexibility, challenging spirit, and future orientation. The significance of this study is that it suggests the need for comprehensive programs such as various extracurricular programs, curricula, and counseling to help and promote the formation of more positive personalities of pre-service early childhood teachers.
