Storytelling which is part of human nature, has changed over millions of years. The development of technology and media has shaped Storytelling into various forms and shapes, and due to the recent spread of smart devices, the influence of interactive storytelling has grown significantly. The technology which allows diverse and natural input of users, have transformed the listener to user and has allowed the user to 'experience' the story rather than 'hear' it. In line with the trend in the development of these technologies, this study seeks to design and implement an interactive tale for children on an ipad platform. Focusing on the interaction aspect, this story is designed mainly for 3-7 years olds, which contains various multimedia elements and interaction elements that use built in technology such as multi-touch technology and microphone technology to allow user input that aline with the context of story. Focusing on children's experience and empathy with the characters of the story, 'Three Little Pigs and the Wolf' contains 22 steps and was published in the itunes Store.

This study aimed to elucidate any differences in fashion consumption tendencies among fashion consumers according to their MBTI personality types and fashion brand sensibility (Chanel vs. Off-White). Differences in fashion consumption tendencies (fashion sensitivity, fashion innovativeness, and fashion ostentation) were determined based on two of MBTI's four bipolar indicators: extroversion-introversion, sensing-intuition, thinking-feeling, and judging-perceiving. It was found that intuitive consumers showed higher fashion innovativeness than sensory consumers. In addition, feeling-type consumers showed more fashion-sensitive and ostentatious fashion consumption tendencies than thinking-type consumers. Fashion brand sensibility acted as a moderator in the relationship between personality type and fashion consumption tendency. Especially, moderating effects of fashion brand sensibility and fashion consumption tendencies were evident in sensing-intuition and judging-perceiving types. Among intuitive consumers, those who preferred Chanel brand sensibility exhibited higher tendencies for fashion ostentation than those who preferred Off-White brand sensibility. However, sensory type consumers showed no difference in fashion ostentation based on their preferred fashion brand sensibility. Interaction effects regarding fashion sensitivity and fashion innovativeness were not found. Among perceiving-type consumers who preferred Chanel brand sensibility, high fashion sensitivity was evident. Conversely, judgment-type consumers who preferred Off-White brand sensibility showed high fashion sensitivity. Interaction effects concerning fashion innovativeness and fashion ostentation were not found.

Applying predictive analytics to enterprise processes is an effective way to reduce operation costs and enhance productivity. Accordingly, the ability to predict business processes and performance indicators are regarded as a core capability. Recently, several works have predicted processes using deep learning in the form of recurrent neural networks (RNN). In particular, the approach of predicting the next step of activity using static or dynamic RNN has excellent results. However, few studies have given attention to applying deep learning in the form of dynamic RNN to predictions of process performance indicators. To fill this knowledge gap, the study developed an approach to using process mining and dynamic RNN. By utilizing actual data from a large domestic company, it has applied the suggested approach in estimating timely stocking in purchasing process, which is an important indicator of the process. The analytic methods and results of this study were presented and some implications and limitations are also discussed.

Railroad logistics transporting freight by train takes charge of 10 or 20 percent of domestic cargos. Railroad logistics users such as transport companies including shippers or Inland Container Depot(ICD) use electronic document(EDI or XML) or input data through WEB to process railroad logistics business. However, as business environments evolving into e-business, it is required to upgrade the legacy railroad logistics process. As the increase of using ebXML-based schema format, it is also needed to improve the electronic documents based on DTD format into those of XML schema format. This study deals with information standard for railroad logistics to improve the railroad logistics business. To this purpose railroad business processes were re-defined through the standard business process modeling methodology. Information model was also derived by defining railroad logistics activities from business process model. And Business Information Entities(BIEs) were defined to design new electronic documents according to the extracted information model. An improved system architecture for railroad logistics was proposed as well. The results of this study will provide an effective and flexible business flow to railroad logistics business.

Due to internal feeding behavior, the oriental tobacco budworm, Helicoverpa assulta ($Guen\acute{e}e$), infesting hot pepper has been regarded to be effectively controlled by targeting egg and neonate larval stages just before entering the fruits. This study aimed to develop an efficient biological control method focusing on these susceptible stages of H. assulta. An egg parasitoid wasp, Trichogramma evanescens Westwood, was confirmed to parasitize the eggs of H. assulta. A mixture of Gram-positive soil bacterium, Bacillus thuringiensis subsp. kurstaki, and Gram-negative entomopathogenic bacterium, Xenorhabdus nematophila ANU101, could effectively kill neonate larvae of H. assulta. A sex pheromone trap monitored the occurrence of field H. assulta adults. The microbial insecticide mixture was proved to give no detrimental effects on immature development and adult survival of the wasp by both feeding and contact toxicity tests. A combined treatment of egg parasitoid and microbial pesticide was applied to hot pepper fields infested by H. assulta. The mixture treatment of both biological control agents significantly decreased the fruit damage, which was comparable to the chemical insecticide treatment, though either single biological control agent did not show any significant control efficacy. This study also provides morphological and genetic characters of T. evanescens.

Two entomopathogenic bacteria, Xenorhabdus nematophila and Photorhabdus temperata subsp. temperata, are known to be potent against the diamondback moth, Plutella xylostella, when the bacteria are injected into the hemocoel. This study investigated any pathogenic effect of their culture broth on P. xylostella by oral administration. Only culture broth of both bacterial species did not give enough pathogenic effects by the oral administration. However, when the culture broth was orally treated together with Bacillus thuringiensis (Bt), both cell-free culture broth significantly enhanced Bt pathogenicity against the 3rd instar larvae of P. xylostella. The culture broth was then fractionated into hexane, ethyl acetate, and aqueous extracts. Most synergistic effect on Bt pathogenicity was found in ethyl acetate extracts of both bacterial species. Thin layer chromatography of these extracts clearly showed that ethyl acetate extracts of both bacterial culture broths possessed metabolites that were different to those of hexane and aqueous extracts. These results suggest that the both entomopathogenic bacteria produce and secrete different factors to give significant synergistic effect on Bt pathogenicity.
