A new free-living marine nematode species of the genus Belbolla Andrássy, 1973 belonging to the family Enchelidiidae is described based on specimens collected from the sediment of a subtidal benthic environmental habitat in the East Sea, Korea. Belbolla wonkimi sp. nov. differs from its congeners by the combination of the following characteristics: a relatively long body (3263-3396 ㎛), the absence of ocelli, nine oesophageal bulbs in the posterior pharynx, well-developed two winged precloacal supplements, longer spicule length(115-130㎛, 1.6-1.8 anal body diameter long), and a triangle-shaped shorter gubernacular apophysis (17-18 ㎛). Comparative tables on the biogeographical and morphological characteristics of Belbolla species are presented. A DIC (differential interference contrast) photomicrograph of the new species is also provided. This is the first taxonomic report on the genus Belbolla from Korean waters.

Clothing is a powerful medium that reflects the environment, situation, and trends of the times. It has been an important subject of semiotic analysis, particularly in East Asia. While Korea, China, Japan, and Mongolia are geographically close, they have each developed unique characteristics in their clothing. These characteristics continue to evolve over time. The purpose of this paper is to explore the modern fashion design characteristics of these four East Asian countries by using the Greimas symbol square. To achieve this, the paper follows a research method consisting of several steps. First, it considers previous studies on the topic. Second, it analyzes fashion collections from Paris, Milan, New York, and London, as well as the Seoul and Cruise collections, from 2013 to 2024. Third, it compares costumes and modern fashion designs of brands known for their East Asian influences. Finally, it applies the framework of the Greimas symbol square to analyze the main elements of dress culture in these four countries and their significance in modern fashion collections. The findings of this study reveal that East Asian costume culture can be summarized into four distinct characteristics in modern fashion. Korea is characterized by "moderation," China by "exaggeration," Japan by "distinctiveness," and Mongolia by "symbolism."

The east-asian mathematics is highly evaluated in mathematics education. In this paper, we search the geometric problems of east-asian mathematics in high school textbooks and various examinations and investigate how to use such problems. We also confirm that the geometric problems of east-asian mathematics can be widely used as real life materials for introducing new mathematical topics, real life applications for mathematical topics, and valuable source for mathematical discourse.

Liriope platyphylla (LP) Wang et Tang has been used for tonic, anti-tussive and expectorant in Korea. In the current study, we found that buthanol fraction of Liriope platyphylla-conditioned media of C6 and primary astrocyte induced the neurite outgrowth of PC 12 cells, which effect was reversed by addition of NGF-antibody. We demonstrated that buthanol fraction of Liriope platyphylla increased the expression and secretion of NGF through RT-PCR and ELISA. (omitted)

The following four aspects should be examined in detail to revitalize North-East Asian agricultural cooperation specialized with Korea, Japan, and China. First, quality and safety standards of agricultural food should be unified. Secondly, it is necessary to build a food security cooperative system in North-East Asia. If three countries build the system, they can overcome a problem such as unstable supply and demand due to natural disaster, and also they can cope with food crisis. Thirdly, to establish North-East Asian Agro-valley is needed. After forming food production belt that connects Korea, Hokkaido in Japan, and the three north-eastern provinces in China, it is possible to realize high value-added agriculture with producing and processing of complementary food for partner country. Lastly, trilateral FTA negotiations should be managed carefully with operating the agricultural special zone and exclusion or prolong period of removal of tariff on sensitive items.

Edwardsiella piscicida is the causative agent of edwardsiellosis, which has caused enormous economic losses worldwide. In our previous research, an attenuated live vaccine known as WED and based on the virulent strain E. piscicida EIB202 can effectively protect turbots against edwardsiellosis via intraperitoneal injection, while vaccination by immersion exhibits a weaker effect. During the development of the immersion vaccine, we surprisingly found the counts of ${\Delta}pEIB202/EIB202$ colonized on zebrafish were 100 times lower than those of EIB202. However, pEIB202 carries 53 predicted ORFs and has several copies in E. piscicida EIB202, impeding the study of its function. Thus, the replication region is located at a 1,980 bp fragment (from 18,837 to 20,816 bp), containing a transcriptional repressor and a replication protein. Moreover, the minimal replication plasmid, named pRep-q77, has low copies in both E. coli and E. piscicida, but is more stable in E. piscicida than in E. coli. This work lays a foundation for further examination of the function of the virulence plasmid pEIB202.

Background : Advanced thymic cancer still remains as an intractable disease. The survival rate of advanced thymic cancer could be increased through chemotherapy and radiation, but the results have not been satisfactory. Objectives : To see whether wheel balanced therapy (WBT) has the therapeutic effects or not on advanced thymic cancer patient. Methods : A patient diagnosed with progression of thymic carcinoma with pleura metastasis visited the East-West Cancer Center (EWCC) on Feb 9th, 2011. The patient was treated with WBT for a period of 9 weeks from Feb 9th to Apr 16th. She stayed 6 weeks in hospital and took oriental medicine prescribed by EWCC. Computed tomography (CT) and blood test were used to evaluate the disease progression of the patient. Results : Mass of chest CT was stable for 2 months. The patient's quality of life improved during her hospital stay. Conclusions : This case study supports WBT may have efficacy in treating advanced thymic cancer patients.

Small RNAs (sRNAs) are widespread and play major roles in regulation circuits in bacteria. Previously, we have demonstrated that transcription of esrE is under the control of its own promoter. However, the regulatory elements involved in EsrE sRNA expression are still unknown. In this study, we found that different cis-regulatory elements exist in the promoter region of esrE. We then screened and analyzed seven potential corresponding trans-regulatory elements by using pull-down assays based on DNA affinity chromatography. Among these candidate regulators, we investigated the relationship between the ferric uptake regulator (Fur) and the EsrE sRNA. Electrophoresis mobility shift assays (EMSAs) and β-galactosidase activity assays demonstrated that Fur can bind to the promoter region of esrE, and positively regulate EsrE sRNA expression in the presence of Fe²⁺.
