Two-dimensional analysis between the explosive performance and the impact sensitivity for methylnitroimidazole derivatives was performed to understand where these new energetic molecules could be utilized. The explosive performance was analyzed with the Cheetah program, while the impact sensitivity was predicted using neural network analysis. Successive nitration of methylimidazole made the molecule more sensitive, but methyltrinitroimidzole appeared to have a relatively good safety characteristic. We recently developed a novel method to analyze the potential usage of new energetic molecules using a two-dimensional chart, where the explosive performance and the impact sensitivity were located on the X-axis and Y-axis, respectively. An analysis of a two-dimensional plot between the performance and the sensitivity indicated that methyldinitroimidazole would be useful for insensitive explosive formulations, while methyltrinitroimidazole was forecasted for use as an ingredient for high explosive formulations.

The number of emigrants along with globalization and internationalization is rapidly increasing. The international migration is creating a new form of acculturation and a new structure of society. Racial or cultural diversity resulting from political, economical, and cultural exchange is drastically increasing. This study aimed to provide policy plans or basic data to improve multicultural acceptability in the future. Accordingly, it was also to set and verify causal effect of multicultural acceptability. For those purposes, a questionnaire was made up based on the literature about acculturation, and a survey was taken in korean. The results are as follows. Dependant variables used in analysis were sub-factors of multicultural acceptability founding three types called 'The Actual Acceptance', 'The Active Acceptance', 'The Passive Acceptance'. It was found that positive effect in multicultural acceptability through media experience was an important factor to reduce discriminant of multicultural community members. Therefore, we need to produce diverse media programs that can improve multicultural acceptability and reduce negative perception of multicultural community members. Additionally, multiculture education to help understanding of other races and other cultures should be developed as subject courses in university.
