The genetic variabilities of second chromosomes of Drosophila melanogaster concealed in Busan natural and experimental populations have been analyzed by the Cy//Pm method. The experimental population was composed of D. melanogaster which had the lethal-free second chromosome, collected Sasang natural population in 1982. The frequencies of deleterious genes were estimated to be 14.3∼25.4% in Busan natural population and 26.5∼27.2% in experimental population. The allelism rates in lethal genes isolated from the natural and experimental populations were calculated to be about 0.76% and 9.76∼14.17%, respectively. The value of elimination by the frequencies of deleterious genes and allelism rate was 0.0106and the effective population size estimated to be about 430 flies at the 6570 days population.

This paper is to reproduce the result of Kim et al. (2014) by deriving a benchmark dose lower bound (BMDL) of lead based on the 2005 cohort data set of Children's Health and Environmental Research (CHEER) data set. The ADHD rating scales in the 2005 cohort were not consistent along the three follow-ups since two different ADHD rating scales were used in the cohort. We first unified the ADHD rating scales in the 2005 cohort by deriving a conversion formula using a penalized linear spline. We then constructed two linear mixed models for the 2005 cohort which reflected the longitudinal characteristics of the data set. The first model introduced the random intercept and the random slope terms and the second model assumed the first order autoregressive structure of the error term. Using these two models, we derived the BMDLs of lead and reconfirmed the "regression to the mean" nature of the ADHD score discovered by Kim et al. (2014). We also noticed that there was a definite difference between the sampling distributions of the two cohorts. As a result, taking this difference into account, we were able to obtain the consistent result with Kim et al. (2014).

This study worked on the qualitative analysis about nomenclature East Sea by the record type in researches related to East Sea shown in the scientific journals. Here in this study, the way of marking is classified as three: 'sole notation of East Sea', 'sole notation of Sea of Japan', and 'simultaneous notation of both'. Based on a total of 4,192 selections from Web of Science DB, the analysis was followed up for change in time series by the notation type, notation type according to the nation that authors belong to, difference in research topic, impact factor, collaboration in research, and co-authorship network. The result turned out in this work that the sole notation of Sea of Japan accounted for the largest portion. It also showed that the rates of sole notation of East Sea and simultaneous notation have kept increasing continuously since the 1990s. Hub nations regarding the research of East Sea is five including Japan, Russia, Korea, USA, and China. In the case of sole notation of Sea of Japan, active collaboration studies are performed in USA, Russia, and China with a focus in Japan. In the case of sole notation of East Sea and simultaneous use, the research rate is relatively high in USA and Japan with a focus in Korea. As to the co-authorship network in the sole notation of Sea of Japan, sort of a "giant component" among different groups has been set up and through which the collaborative works are actively underway. However, it was found that the research of sole notation of East Sea is dispersed into small groups on the base of relevant individual institution.

The morphological variations and habitat environment of the Zostera asiatica Miki (Zosteraceae) were examined in the waters off the eastern coast of Korea and Akkeshi Bay of Japan. In this study, we report new habitat of Z. asiatica along the eastern coast of south Korea； Gonghunjin, Donghori, Youngdong and Chilpo. Z. asiatica is found at the depth of 8∼15 m in these areas. However, Z. asiatica grows at the depth of 3 m in Akkeshi Bay of Japan. The sediment of habitats in the eastern coast of Korea were principally composed of sand. The stems were 64.0∼75.7 cm long in mature plants with flowering shoots and the leaves were 11.0∼15.0 mm wide for Korean populations. Plants from Akkeshi Bay of Japan had stems of 187.0∼234.0 cm in length. The difference in size are considered to be due to the depth of habitats. In spite of the significant morphological difference between Korea and Japan population of Z. asiatica, there was no difference in ITS sequences.

The purpose of this study is to analyze the relationship between the two factors and the influence of Chinese cultural orientation on the change of physical dry environment in the domestic Chinese residential area. To this end, Hofsted's cultural dimension theory, which can quantitatively define and compare the national culture, is used to investigate the cultural orientation of China. The association was analyzed. Through this study, it was confirmed that the collectivist and uncertainty-avoidance tendency of the Chinese influenced the formation and change of the dry environment of the Chinese residential area in Daelim 2-dong. This study is meaningful in confirming that the cultural orientation of the migrant community affects the formation and change of collective residences, and through this, it can be used as basic data in preparing policies suitable for various migrant communities including Chinatown.

The major purpose of this study is to explore the effect of the presentation undo combined by main four media(moving Image, audio, turf image) of web contents on the children's information processing process. So children were assigned to one of five experimental medium conditions: 'moving Image1 (auditory-visual redundancy)', 'moving Image2 (auditory-visual dissonance)', 'text', 'text-with-image', 'audio'. Results indicated that the moving image was found to be the most effective transmitter of internet news information for children's recall. And the recall advantage of moving image was found to be particularly pronounced for verbal information supplemented with redundant visual.
