Lately, countries around the world have been focusing their efforts on shifting from conventional industries to innovative-technology-based industries, and committing their competencies to growing startups as an important next-generation industry that will lead national competitiveness. However, there are inadequacies in studies and methods that analyze research and development (R&D) investment and startup performance from a technology perspective, which is an innate nature of startups. This study analyzed the correlation between a startup's R&D investment and its performance. More specifically, this study performed a correlation analysis and a panel analysis on startups that reached KRW 100 billion in revenue; these analyses were not applied in previous studies. The following are the findings: first, the R&D investment percentage of startups located in other regions was relatively higher than that of those in the Seoul metropolitan area, and second, when a startup's operating margin and net profit margin were high, its R&D investment percentage tended to go higher. In conclusion, this study identified that R&D performance resulting from R&D investment was a core competency factor in the success of a startup.

In this study, we investigated the argumentations of group and classroom discussions in socioscientific issues (SSI) discussion classes. Twenty-seven high school students participated in the SSI discussion classes on nuclear power generation. We observed and recorded the classes and also conducted semi-structured interviews. For the analyses, we revised a previous framework that was developed to analyze dialogic argumentations in the context of SSI. The analyses of the results indicated that there were more discourse schemes in the classroom discussions than the group discussions which are related to awareness and openness to multiple perspectives, evidence based reasoning, and on-going inquiry and skepticism. And there were few discourse schemes related to moral and ethical sensitivity in the group and classroom discussions. Various grounds, data, and information were presented in the classroom discussions. Students concentrated on carrying their claims and were not able to sympathize with and accept other opinions. Therefore, there were few discourse schemes to reach consensus. In addition, they perceived classroom discussions as competitive and actively rebutted other claims or grounds. The levels of argumentation were also high in the classroom discussions. The group discussions were held in relaxed atmosphere, and they asked the opponents more for clarification or additional information and evidences. However, classroom discussions were held in serious atmosphere, and they actively queried the validity of the claims or grounds. Based on the results, some suggestions to implement SSI discussion classes were discussed.

The analysis and comparison on the usage of public cremation facilities located in Seoul through online reservation service of ehaneul funeral information system by area from Jan. 1, 2011 to Dec. 31, 2017 showed that among 314,877 in the number of bodies using the facilities, 225,828 (or 71.7%) belonged to Seoul citizens and 89,049 (or 28.3%) belonged to people living in other area than Seoul, such as Goyang city, Gyeonggi-do and other local governments. Therefore, there appeared that the Seoul citizens could not get the timely cremation service but instead extended the funeral service to 4 to 5 days or had to go to the remote area for cremation. This trend gets severe every year. To solve these problems, it is recommended that Seoul city government makes effort of constructing or expanding the public cremation facilities in cooperation with other local government of the area whose residents show high rate of using Seoul public cremation facilities and that Seoul city government expands or builds its own public cremation facilities in mid- and long-term. In addition, the local government of other area around Seoul needs to expand their use rate of their own (4) public cremation facilities or raise the creation fee for the residents from other areas, thus trying to dispersing and controlling the demand for the cremation.

This paper analyzed class satisfaction and perceived learning achievement to the interaction type on e-learning in university. To achieve the study's objective, one course with and another course without learner-instructor interactions were selected. A total of184 student-respondents completed the questionnaire. Accordingly, more learner-content and learning-system interactions were noted in the course with learner-instructor interactions. Moreover, a correlation was observed between interaction, class satisfaction, and learning achievement. Learner-instructor interactions indicated the highest effect on both educational satisfaction and perceived learning achievement, followed by learner-system interactions on class satisfaction, and by learner-instructor interactions on learning achievement. Recommendations were then formulated based on the foregoing findings. First, workshops or training focusing on content development and on how to present the course should be provided to the instructors. Second, learner-instructor interactions should be activated in the course through various means. In this study, although learner-learner interactions was not given focus, future studied should delve into how learner-learner interaction should be activated and considered.

This study is designed to figure out what kind of female images TV dramas have represented from 2000 to 2007 and what kind of relationship these images and the actual roles the female characters perform have in the drama. The total number of dramas analyzed is 27, and 152 female characters are analyzed. The result finds that 45% among 152 characters is in her 20's, and most of them play the main roles. Only 4 dramas use 3,40's female characters as main figures. Most 4,50 female characters play mother or grand mother roles of main characters, and they usually interrupt main character's love relationships or don't play any meaningful roles for the narrative. The old female characters over her 60's tend to play foolish and ridiculous roles and don't show any physical charms. The female main characters are beautiful and young, and the more they play good roles, they have better natural beauty comparing the bad characters. The youth and beauty of main characters helps the owner to earn the love of main male characters. It's obvious that the dramas show that female's body as physical capital to achieve higher class and power.

This study was intended to provide management directions through the provision of tree spatial information as basic data for the preservation of Gyerim(legal historical site), which is located in Gyeongju city, Gyeonsangnam-do, Korea. As a result of the survey of the entire forest, there are a total of 25 species and 510 individuals growing trees. Of these species, 14 species are native and 14 are introduced species. Apart from Sophora japonica, Zelkova serrata, Celtis sinensis, most of the introduced species were adopted without historical basis after designation as a historical site. By a ratio of 36% to introduced species(including 3% of naturalized species; Ailanthus altissima), the historical heritage was significantly damaged. Gyerim, which has over 2,000 years of history, has a total 15 individuals(2.9%) large trees(over 100cm DBH). Ten of these are Salix glandulosa, and in the past, most of this area was considered a Salix glandulosa forest. Currently, however, there are many small trees(under 20cm DBH) for the next generation of growth and the Salix glandulosa forest will continue to decline. Furthermore, most small trees were afforested, so the historicity and place features as a mythological forest will quickly fade.
