  • The purpose of the study is to figure out the difference in preference of clothes between Korean and Chinese female college students, who share similar ethnic traits despite having different sociocultural backgrounds and environment, and see the differences in their body image and body satisfaction. The questionnaire-based survey for the study was conducted for about a month and a total of 449 copies of the questionnaire were collected for the final research. For the research method, we examined the differences in clothes preference and fit between Korean and Chinese students, and then the corresponding differences in body image and body satisfaction. The result showed significant differences in the categories of skirt length, pants length, upper garment fit, and lower garment fit. Korean students preferred slim fit clothes, while their counterparts preferred natural fits. A comparison of body image between Korean and Chinese female students showed that the Korean students had lower body satisfaction levels, and viewed themselves as fat even though they were slimmer than their counterparts. The conclusion of the analysis was that compared to Korean students the Chinese students pursued a more comfortable and casual style, preferring unique and diverse designs instead of simply following a fashion trend.

  • The importance of designing urban building complexes so that they obtain 'urban' power, rather than become isolated from the surrounding urban context, has been well recognized by both researchers and practitioners. Nevertheless, most current discussions are made from architects' personal experiences and intuition, and lack a quantitative understanding, to which obstacles include an in-depth exploration of the 'urban' power between building complexes and the urban environment. This paper attempts to measure this feature of 'urban', i.e., 'urbanity,' through a new analytical approach derived from the opendata environment. Three measurements that can be easily collected though the Google Maps API and Open Street Map are applied herein to evaluate high or low values of urbanity. Specifically, these are 'metric depth', i.e., the scale of extended public space, 'development density', i.e., density and distribution of point of interests (POIs), and 'type diversity', i.e., diversity of different commercial types. Six cases located in Japan, China and Hong Kong respectively are ranked based on this analytical approach and compared with each other. It shows that Japanese cases, i.e., Osaka Station City and Namba Parks, Osaka, obtained clearly higher values than cases in Shanghai and Hong Kong. On one hand, the insight generated from measuring and explaining 'urban' power would help to assist better implementation of this feature in the design of urban building complexes. On the other hand, this analytical approach can be easily extended to achieve a large-scale measurement and comparison among different urban building complexes, which is also helpful for design practitioners.

  • Objectives: This study was conducted to investigate the nutritional status and dietary behavior of Korean and Chinese elementary school children using Nutritional Quotient (NQ). Methods: The survey was conducted by distributing questionnaires to the parents of the child, after selecting four elementary schools located in Pusan city of Korea and three elementary schools located in Luoyang city, Henan Province of China, from Grade 1 to Grade 6 in each school. Results: The NQ scores of Korean children and Chinese children were 64.99 and 66.57, respectively, which did not show a statistically significant difference. Korean children significantly showed higher diversity score (p<0.001) than Chinese, but Chinese children significantly showed higher moderation (p < 0.001), regularity (p < 0.001) and practice score (p < 0.01) than Korean. NQ grades showed a statistically significant difference. According to food security of the household, NQ scores of the Chinese children of secure household were significantly higher than those of food insecurity household (p < 0.01). In particular, it showed a significant difference in the practice (p < 0.001), moderation (p < 0.05) and regularity score (p < 0.05). Korean children's NQ score showed a significant correlation with the score of following the Dietary Guidelines of parents, but Chinese did not show such a correlation. Conclusions: There were differences in children's dietary behaviors and parents' impact to children's dietary attitude between Korean and Chinese. NQ developed for Korean could be successfully applied to Chinese.

  • The objective of this study was to analyze the phylogenetic composition of bacterial community in the soil of an earth-cave (Niu Cave) using a culture-independent molecular approach. 16S rRNA genes were amplified directly from soil DNA with universally conserved and Bacteria-specific rRNA gene primers and cloned. The clone library was screened by restriction fragment length polymorphism (RFLP), and representative rRNA gene sequences were determined. A total of 115 bacterial sequence types were found in 190 analyzed clones. Phylogenetic sequence analyses revealed novel 16S rRNA gene sequence types and a high diversity of putative bacterial community. Members of these bacteria included Proteobacteria (42.6%), Acidobacteria (18.6%), Planctomycetes (9.0 %), Chloroflexi (Green nonsulfur bacteria, 7.5%), Bacteroidetes (2.1%), Gemmatimonadetes (2.7%), Nitrospirae (8.0%), Actinobacteria (High G+C Gram-positive bacteria, 6.4%) and candidate divisions (including the OP3, GN08, and SBR1093, 3.2%). Thirty-five clones were affiliated with bacteria that were related to nitrogen, sulfur, iron or manganese cycles. The comparison of the present data with the data obtained previously from caves based on 16S rRNA gene analysis revealed similarities in the bacterial community components, especially in the high abundance of Proteobacteria and Acidobacteria. Furthermore, this study provided the novel evidence for presence of Gemmatimonadetes, Nitrosomonadales, Oceanospirillales, and Rubrobacterales in a karstic hypogean environment.

  • Mahaenggamsuk-tang (MHGS) has been widely used in Korea and China for the treatment of various diseases. MHGS was constituted the Ephedrea Herba, Armenicae Semen, Glycyrrhizae Radix and Gypsum Fibrosum. In this study, we have made three different solvents extract as MHGS water extract (MHGS-W), MHGS 50% EtOH extract (MHGS-50E), and MHGS 100% EtOH extract (MHGS-100E). The MHGS-W, MHGS-50E and MHGS-100E showed the discernible difference patterns on HPLC analysis. Furthermore, MHGS-50E and MHGS-100E significantly increased the DPPH and ABTS radical scavenging effects than MHGS-W. In addition, the MHGS-50E and MHGS-100E also inhibited significantly nitric oxide (NO) and prostaglandin E2 (PGE2) production, and inducible nitric oxide synthase (iNOS) cyclooxygenase-2 (COX-2) protein expression in RAW264.7. On the other hand, MHGS-50E and MHGS-W showed remarkable protection on the HT22 cell via heme oxygenase (HO)-1, but MHGS-100E did not show. The results of this study proved that MHGS-50E has greater potential therapeutic uses by exerting antioxidant, anti-inflammatory and neuroprotective effects compared to MHGS-100E, MHGS-W. Our study suggests that the different solvent might be affected the biological activities when make the traditional herbal medicines including MHGS.

  • To examine the detectability of the aerosol and/or Yellow dust from China crossing over the Yellow sea, three works carried out as follows , Firstly, a comparison was made of the visible(VIS), water vapor(WV), and Infrared(IR) images of the GMS-5 and NOAA/AVHRR on the cases of yellow sand event over Korea. Secondly, the spectral radiance and reflectance(%) was observed during the yellow sand phenomena on April, 1998 in Seoul using the GER-2600 spectroradiometer, which observed the reflected radiance from 350 to 2500 nm in the atmosphere. We selected the optimum wavelength for detecting of the yellow sand from this observation, considering the effects of atmospheric absorption. Finally, the atmospheric radiance emerging from the LOWTRAN-7 radiative transfer model was simulated with and without yellow sand, where we used the estimated aerosol column optical depth ($\tau$ 673 nm) in the Meteorological Research Institute and the d'Almeida's statistical atmospheric aerosol radiative characteristics. The image analysis showed that it was very difficult to detect the yellow sand region only by the image processing because the albedo characteristics of the sand vary irregularly according to the density, size, components and depth of the yellow sand clouds. We found that the 670-680 nm band was useful to simulate aerosol characteristics considering the absorption band from the radiance observation. We are now processing the simulation of atmospheric radiance distribution in the range of 400-900 nm. The purpose of this study is to present the preliminary results of the aerosol and/or Yellow dust detectability using the Ocean Scanning Multispectral Imager(OSMI), which will be mounted on KOMPSAT-1 as the ocean color monitoring sensor with the range of 400-900 nm wavelength.

  • We analyzed partial sequences of cytochrome b (cyt-b), a mitochondrial DNA (mtDNA) gene, to determine the genetic relationships between six horsehead fish species: Branchiostegus japonicus, Branchiostegus albus, Branchiostegus auratus, Branchiostegus argentatus, Branchiostegus wardi, and an unidentified Branchiostegus species. The specimens were collected in Korea, China, Japan, and Vietnam. We compared their molecular phylogenetic relationships inferred from mtDNA cyt-b sequences with an osteological analysis. The unidentified species, B. sp., was similar to B. albus in terms of the lack of triangular silver-white dot at the posterior region of eyes (vs. large one present in B. japonicus), but was also similar to B. japonicus in terms of the presence of a straight-shaped first hemal spine (vs. a curve-shaped hemal spine in B. albus). Analysis of the mtDNA cyt-b sequences indicated that the smallest estimated sequence divergence was between the B. japonicus and B. sp. (0.70-0.94%), whereas the largest difference was between B. auratus and B. argentatus (23.06-23.36%). Both the maximum parsimony and maximum likelihood trees showed that the B. sp. was closely clustered with B. japonicus, and that B. auratus was most distant from the other species. When comparing the osteological characters, UPGMA tree showed that the B. japonicus and B. sp. were the most closely clustered species, and B. auratus was the most distantly clustered fish relative to the other species. The shape of the nasal, otolith and first hemal spine was informative for distinguishing B. auratus from the other species. These osteological differences were consistent with the differences in mtDNA.

  • International trade is one of the primary ways that non-native species spread worldwide. Korea and China are geographically close and have a large mutual trade volume. To investigate the population movement of the invasive whitefly(Bemisia tabaci Gennadius) between the two countries, we compared the biotype distribution, insecticidal response, and the TYLCV(tomato yellow leaf curl virus) viruliferous rate of local populations collected in 2019. Based on the mitochondrial DNA COI sequences of B. tabaci, only the Q biotype was found in all populations in Korea, whereas the B biotype (14.3%) and Q biotype (85.7%) were found in China. In the haplotype composition of the B. tabaci Q biotype, only the Q1 group[Q1H1(79.8%) and Q1H2(20.2%)] was observed in China, but the Q1 group [Q1H1(1.7%) and Q1H2(97.5%)] and the Q2 group(only one individual) were found in Korea. The Korean populations showed high mortality(more than 80%) from 15 commercial insecticides, but the Chinese populations showed significantly low mortality from eight insecticides. No TYLCV infections were observed in the Korean populations while the average TYLCV viruliferous rate was 21.4% in the Chinese populations. Taken together, the results suggest that the population structures of B. tabaci in the two countries are different and may have different immigration histories.

  • There have been technologically distorted naturalization and overzealous digital culture in the formation and development of digital society in Korea. While the suppressive aspects of the 'neo-'authoritarian control and regulation have been excessively centered on the Internet, the autonomous actions of online users from below, with regards to their roles in agenda-setting function, have been evolved as the political. This paper aims to investigate the specificities in the developmental mode of digital technology in Korean society since the mid-90s. In this paper, 'techno-surplus' depicts the state that the abnormal is embedded within a technological artifact beyond its receptive ability. 'Techno-surplus society' designates such an extreme case of specifying technological surplus. In fact, the term of 'techno-surplus society' can be used for a metaphor symbolizing our society, in which social distortion and abnormality caused by 'techno-surplus' have been quite frequently happening, in its comparison to a degree of normality in the institutional politics. This paper explores the local specificities of 'techno-surplus society', in which the regressive aspects have stand out as being more different from the technological developments in China, Japan and the U.S.

  • Yanbian area is a region with great interests to Cultural-Historically Korea as well as China. Cultural-historic study on Yanbian are lots of researches but can find few mapping for sites. This study aimed to make a map and analyze characteristics of distributions in the Cultural-Historic sites of Yanbian using Google Earth. We made a distribution map from stone age to Qing Dynasty. Symbology for mapping made color symbols by time series and categorical symbols. As a research finding, Sites of Balhae and Yuo-Geum age account for large parts in comparison with other ages in Yanbian. Especially, sites of Goguryeo, Balhae and Yuo-Geum age showed spatio-temporal structure of accumulative layers Characteristics of distributions is located in basin and stream area in the early age, and after then historical period moved to hilly sides and mountainous areas. The result of this research is expected to offer information for relevant follow-up studies of Cultural-Historic sites.
