  • Traditionally, self-efficacy, burnout and engagement are defined as work related states of mind, and formally speaking, students are not employees. But, we assume that from a psychological perspective, student core activities can be considered work. Therefore, based on SCT(social cognitive theory), we examine the mediating role of self-efficacy in the prediction of student burnout and engagement, and also the mediation of burnout and engagement between self-efficacy and performance(GPA). There is no research to date wether there would be mediating role of these variables between past success and performance. These effects were analysed in the context of mediating role of the variables in a university in a sample of 438 students. This study utilized a convenience sample drawn from various major scholar area. Results of structural equation modeling analyses were consist with a full mediation model in which academic past success predicts self-efficacy, which in turn, predicts student burnout and engagement. Also our proposed model showed that burnout and engagement are partial or full mediating variables between self-efficacy and performance. Our study's findings provide evidence that engagement fully accounted for the relationship between self-efficacy and performance, and burnout partially explained the relationships. These findings aligns with the general theorizing supported by JD-R model and SCT(social cognitive theory). More specifically, it builds on the JD-R literature as it tests one of the proposed mechanisms in the relationship between job resources and work engagement. Implications of study are discussed, together with limitations and suggestions for future research.

  • For the study of the development of Asia map made by european map makers, one should consider Gog and Magog which existed in the maps for more than 700 years. Gog and Magog are described as an apocalyptic people in the Bible and medieval literature, and they are important elements in medieval mappaemundi and early modem world maps. This study classified representation types of Gog and Magog in old western maps. Maps were classed in to six categories according to the location and ethnic groups which they represent, and they were discussed in cartographic context. The maps until the fourteenth century place Gog and Magog, shut up by Alexander, near Caspian Sea. In the fifteenth century, Gog and Magog were described as Closed Jews in maps. From the sixteenth century they appear in the far northeastern part of Asia and they are named as Amagog or Ung and Mongul. In the mid-seventeenth century, they are located in Eastern Siberia by French cartographers. But with the expansion of geographic knowledge, Gog and Magog disappeared completely in the eighteenth century. In general, God and Magog were represented on the basis of traditional lore rather than on the Bible, and they became one means of mapping others of European community.

  • It is important to know science terminology when learning science. In terms of linguistic and psychological perspectives, the context of encountering a terminology for the first time is critical. If a student has not learned the terminology properly the first time, it might cause misconceptions or be a barrier in following learning. This study aims to identify how careful science terminology are used in science textbooks, and the relationship of using science terminology between science curriculum and middle school science textbooks in the 2009 National Curriculum. In addition, the educational need, the importance of science learning, proper time for teaching, & difficulty of the terminologies have been surveyed among teachers and students. As results of study show, only 25% of terminologies in science textbooks have appeared in the curriculum, and about 10% have been used in middle school science textbooks prior to science curriculum. The survey results suggested that many of those terminologies could cause problems in teaching and learning situation. The solution for them have been divided into the following: avoiding usage in textbook prior to curriculum, using earlier in textbooks, using earlier in curriculum, and reflecting curriculum precisely in the textbook. In general, the curriculum needs to state performing objectives concretely. And it is needed to examine science terminology advertently when writing textbooks.

  • Teachers expect team-based project learning to help students develop collaborative and real-world problem solving skills. In practice, however, students tend to solve problems with simple division of labor, and there is a tendency that learning transfer does not occur in solving problems. The purpose of this study is to develop a collaborative learning model based on the transactive memory system (TMS) and to verify its effectiveness. The collaborative learning model based on the TMS is composed of three stages. The first stage is developing TMS. In this stage, the students learn physics concepts and make knowledge about the expertise of group members through peer instruction. The second stage, activating TMS, is building trust through solving well-defined problems for developing near-transfer. And in the third stage, applying TMS, the students solve an ill-defined problem based on real-world context for practicing far-transfer. Based on this model, a 15-week program including two projects on geometric optics and sound waves was developed and applied to 60 college students. The data for five weeks of one project were collected and analyzed. As a result, the TMS of the experimental group with the TMS-based collaborative learning model improved stepwise. Whereas, the difference between the first week and the last week was statistically significant, while the TMS change of the comparison group using the general project learning model was not significant. Also, the experimental group showed that the learning transfer occurred better in the project than the comparison group. A collaborative learning model based on TMS can be used to learn how students gain synergy through collaboration and how students collaboratively transfer the learned concepts in problem solving.

  • As a way of identifying users' image needs for improved effectiveness of image search, there have been recent research approaches to examine contextual factors in image needs with multiple perspectives. In this line of research, this study examined a total of 70 unsuccessful image searches for the purpose of investigating users' image needs. In order to achieve the purpose of this study, in particular, the characteristics of image needs, contextual factors on image needs, and image queries were investigated. The findings of this study demonstrated that information needs from the failed image searches are categorized primarily into specific and general/nameable categories. More importantly, these information needs are embedded with multiple contextual factors, primarily, task purpose and use purpose. With an analysis of detailed use purposes for image, illustration use was found most in this data set. For query analysis, the type of unique/refined image query was revealed primarily. As the results of this study were found similar to the findings of previous studies, it is possible to characterize the image needs from the failed image searches. In addition, the findings of this study are expected to be useful to the design and service of image retrieval.

  • The study intended to explore not only what are the outcomes of employees' participation in corporate philanthropic activities, such as donation or volunteering, but also how their participation achieves the outcomes. In general, a specific corporate context is likely to lead employees to take part in corporate philanthropy in involuntary or passive ways. With this characteristics, employees' donation or volunteering at a working place has an impact on changes in their attitudes toward corporate social philanthropy and organizational commitment. The study also assumes that the changes in employees' attitudes have a mediate effect on their organizational commitment. The study conducted a survey for about 300 employees working at one of corporations in Seoul Metropolitan area. Based on a structural equation modelling analysis, the results showed that there was an indirect relationship between staffs' participations in corporate philanthropic activities and organizational commitment, which was mediated by employees' assessment and attitudes toward corporate philanthropy. Despite a limitation of the study sample, the study provided both an academic ground to discuss on employees' participation in corporate philanthropy, and a practical ground for corporate leaders to strategically consider how to encourage employees to participate in corporate philanthropic activities and to achieve its goal.

  • Parody has recently prevailed as one of the important techniques of creation in art. The purposes of this study are to reaffirm the pos-ition of fashion as an art by clarifying parody depicted in fashion and to make an opportunity to reconsider the meaning of creation in fashion design through the significance of par-ody. For these purposes, documentary studies about parody in literature and art which had been discussed more often were preceded as a framework of this research. framework of this research. Basedd upon that, parody phenomena in fashion as well as art were analyzed. The synthetic results are as follows ; 1. Parody is a kind or critical technique and can be conceived as a process of creation. The established primary style (material) which is well-known and familiar is imitated and then is recreated in new manner through the three types of parodization, that is, the change of its external form, the change of its internal mean-ing and the shift from its place (i.e. displace-ment). 2. Parody in fashion is also analyzed based upon the three types of parodization which designer's will and expression is necessarily required. First, the parody through the change of external form is to have its effect of novelty, unexpectedness, playfulness, wit, mackery, satire, irony, paradox by changing the form of the original through imitation with similarity, transformation, exaggeration, em-phasis. Second, the parody through the change of internal meaning is to bring about paradox, irony, contempt, satire, unex-pectedness by applying the original to inappro-priate subject through its substitution, inver-sion. Third, the parody through displacement is to pursue a jarring incongruity that results from shifting the original to other context. Its effect consists of paradox, unexpectedness, playfulness, ridicule, mockery, satire, irony. In general, the parody technique in fashion can be used to have an intention of expressing seriousness, playfulness, satire, grotesque. The representative designers using the parody technique are Lagerfeld, Ricci, YSL, Yama-moto, Castelbajac, Gaultier, Mugler, West-sood, Steiner and so on. 3. Parody is the technique which imitates and then recreates the preceding style ; is at the same time the method which challenges the existing concept of originality-singleness and uniqueness. It reflects the more flexible concept of modern creation in art as well as fashion. The imitation as the creation, the characteristic of parody is recognized as an creative expressiveness, publicity, intention. Thus it differenciates from copy which is uncritical mimicry.

  • When a pregnant woman experiences cardiac arrest, resuscitation is of the utmost importance. Cardiac arrest in pregnant women differs from cardiac arrest in the general population since both mother and fetus need to be taken into consideration. In the event of cardiac arrest, determining whether to deliver the baby is significant. Cardiopulmonary resuscitation is not always successful, and the survival rate depends on the speed and precision of the procedure. In this study, we focus on the case of a 30-year-old pregnant woman who experienced cardiac arrest and whose family was quick to perceive her condition and call the hospital. A witness performed initial cardiopulmonary resuscitation, while rescue workers performed the advanced procedure. In this case, the patient and baby received proper treatment and left the hospital after six days. It is extremely rare for a pregnant patient to achieve return of spontaneous circulation (ROSC) or receive advanced cardiac life support before reaching the hospital. However, the woman in question in this study achieved ROSC and received both cardiopulmonary resuscitation before reaching the hospital and advanced cardiac life support at the hospital. The specifics of the case are reported in the context of a literature review.

  • This study provides an illustrative example of using the multivariate generalizability theory. Specifically, it investigates relative effects of each error source, and finds optimal measurement conditions for the number of items within each content domain that maximizes the reliability-like coefficients, such as a generalizability coefficient and an index of dependability. The method is based on teacher recommendation letters and self-introduction letters, using an analytic scoring method in the context of selection of mathematically gifted students by observation and nomination. This study analyzed data from the 2011 academic year in the science education institute for the gifted, which is attached to the university located in the Seoul metropolitan area. It should be noted that the optimal scoring structures of this study are not generalizable to other selection instruments. However, the methodology applied in this study can be utilized to find optimal measurement conditions for the number of raters, the number of content domains, and the number of items in other selection instruments self-developed by many institutions including: the education institutes for the gifted at provincial offices of education, gifted classes, and the science education institutes for the gifted attached to universities in general. In addition, the methodology will provide bases for making informed decisions in selection instruments of the gifted based on measurement traits.

  • This study proposes a Korean sentimental analysis algorithm that utilizes a letter-unit embedding and convolutional neural networks. Sentimental analysis is a natural language processing technique for subjective data analysis, such as a person's attitude, opinion, and propensity, as shown in the text. Recently, Korean sentimental analysis research has been steadily increased. However, it has failed to use a general-purpose sentimental dictionary and has built-up and used its own sentimental dictionary in each field. The problem with this phenomenon is that it does not conform to the characteristics of Korean. In this study, we have developed a model for analyzing emotions by producing syllable vectors based on the onset, peak, and coda, excluding morphology analysis during the emotional analysis procedure. As a result, we were able to minimize the problem of word learning and the problem of unregistered words, and the accuracy of the model was 88%. The model is less influenced by the unstructured nature of the input data and allows for polarized classification according to the context of the text. We hope that through this developed model will be easier for non-experts who wish to perform Korean sentimental analysis.
