  • This study explores the divergence of grounded theory focused on the differences of Glaser and Strauss. Grounded theory has been divided into two versions, Glaser version and Strauss version. Two versions are different in research methodology. Therefore, it is important for us to choose one of these two version. There are many grounded theory researches or qualitative researches by grounded theory approach in Korea. But Theses researches has been studied only Strauss version. Therefore this article introduces the differences of Glaser method and Strauss method in various aspects of research methods: basic logic of research process, core category and basic social process, and coding methods - especially axial coding, selective coding and theoretical coding. Glaser and Strauss argued differently in many aspects of grounded theory method.

  • With the recent slowdown of R&D budget growth rate, efficient resource allocation, operation and management of national R&D is becoming more important. At this point, recognizing the necessity of systematic and scientific research on the national R&D itself, this study analyzed previous researches on national R&D of Korea. In this study, based on the previous researches and laws, national R&D was classified according to the major stages such as planning, selection, management, performance and so on. Secondly, by using the classification criteria forged, previous researches on the national R&D published in domestic journals for the last 5 years were divided into 12 categories, and the status of researches in each field was analyzed. Lastly, through network analysis, linking status and influence of each fields were identified by using co-classification information of research literatures. As a result of this research, the performance related fields were the most active ones in terms of the number of research literatures, and connections with other fields, while the fields such as selection and infrastructure were lacking in the number of research and linkage. This study can find its meaning in identifying research fields that need more studies and connections with other areas by systematic analysis of previous studies on Korean National R&D.

  • To improve the efficiency of hairtail trolling, it is important to gain an accurate understanding of the distribution of fish based on their diurnal vertical migration patterns. This study evaluated the vertical distribution of hairtails through catch efficiency tests using vertical longlines. Five replicate tests of the efficiency were carried out on the eastern coast of Jeju Island from August to September 2016, from 11:00 AM to 03:00 PM in the daytime and 11:00 PM to 03:00 AM in the nighttime. The fishing gear was composed of 20 hooks per line set, numbered in order from the first hook near the surface to the last hook on the seabed. The depth of the first hook was 18 m, and that of the last hook was 86 m. Pacific saury was used as the baits. In total, 10 sets of fishing gear were used per trip. After fishing, we counted the hairtails at each numbered hook, which were summed up both by number and in aggregate. A total of 232 hairtails were caught using 2,000 hooks: 193 individuals at daytime and 39 at nighttime. The hook rate was 11.5% : 9.6% at daytime; 2.0% at nighttime. For both daytime and nighttime catches, there were variations in the hook rates at each numbered hook. In the daytime, a maximum of 28.5% catches occurred at hook number 18, followed by 21.4% at number 20, and 10.7% at number 17, accounting for 60.6% of the daytime hook rates. In the nighttime, a maximum of 23.0% catches occurred at hook number 1, followed by 15.3% at hook number 4 and 9, accounting for 53.6% of the nighttime hook rate. Based on the above results, hairtails are usually distributed in deeper region in daytime, whereas they occur near the surface in nighttime. Therefore, it is necessary to position trolling lines according to diurnal vertical distribution layers of hairtails for fishing efficiency.

  • The purpose of this study is to investigate the trends of character-related research in science education by analyzing science education research literatures in South Korea. To this end, literatures on character were extracted from the KCI-listed journals and theses from 1990 to December 2016, and analyzed according to the criteria such as terms relating to character, year of publication, research design and method, and research content. A total of 54 KCI-listed papers and 67 theses were extracted. As a result, 46%, 49%, and 5% of the researches include the terms like character, ethic, and moral in their titles. According to the year of publication, it was found that the number of research papers related to character increased rapidly by more than two times in 2012 as compared to the past years. According to research objects, researches about gifted students were the most common, and when considering the ratio of gifted students to general students, many studies related to character concentrated on gifted students. Starting 2009, research papers on qualitative and hybrid research design begin to advance as compared the number of papers in quantitative research design. With regards to research methods used, seven methods were classified; five of them ranged from 16% to 19% while interpretive research method was 12% and test tool validity study was the lowest at 2%. By extracting 30 representative keywords so as to analyze the contents of character-related researches, we found various implications to character in relation to nature and researches about SSI, etc. As time passed by, the contents of character-related research in science education became more diversified and the number of researches increased. New research contents appeared due to the needs of the times.
