Stathmin 1 is a microtubule destabilizer that plays an important role in cell cycle progression, segregation of chromosomes, clonogenicity, cell motility and survival. Stathmin 1 overexpression has been reported in malignant hematopoietic cells and Stathmin 1 inhibition reduces the highly proliferative potential of leukemia cell lines. However, during the differentiation of primary hematopoietic cells, Stathmin 1 expression decreases in parallel to decreases in the proliferative potential of early hematopoietic progenitors. The scope of the present review is to survey the current knowledge and highlight future perspectives for Stathmin 1 in normal and malignant hematopoiesis, with regard to the expression, function and clinical implications of this protein.

An epidemiological study was conducted to investigate five diarrhea-causing pathogens (coronavirus, rotavirus, E. coli, Cryptosporidium, Giardia) using a rapid diagnostic kit in Hanwoo calves with diarrhea in Chungcheongbuk-do, Korea, from 2018 to 2021. A total of 22,417 fecal samples were collected from calves under 1 year of age; of those, 13,518 (60.3%) were positive for five bovine diarrhea antigens. The antigen positivity rates for rotavirus, coronavirus, E. coli, Giardia, and Cryptosporidium were 34.5%, 11.0%, 8.2%, 4.7%, and 2.0%, respectively. The prevalence of the five pathogens in calves was statistically higher in autumn and winter. The highest prevalence of the pathogens was observed in the under 1 month age group, and the incidence of diarrhea decreased with age. Rotavirus was a major pathogen in calves under 1 month of age, whereas the prevalence of E. coli increased with age. This study provides epidemiological evidence of the prevalence of calf diarrheal pathogens in Chungcheongbuk-do, Korea, which will facilitate early diagnosis and development of measures against calf diarrhea.

A single specimen of Bathygobius cotticeps (41.0 mm SL) was collected from the rocky pools of intertidal zone of Jeju-do Island, Korea. This species is characterized by having VI-I, 9 dorsal fin rays, I, 8 anal fin rays, scales on cheek and opercle, 23 predorsal scales, 38 longitudinal scales, 24 pectoral fins, 7 free rays on upper pectoral fin, each divided to 5-7 branches, cephalic sensory canal pores H and K fused, and the middle of pelvic frenum curved inwards smoothly. We propose a new Korean name, "Bi-neulmu-nui-mang-duk" for the B. cotticeps based on the presence of scales on the cheek.

This study was survey a flora and life form spectrum of 11 uninhabited islets, in jeju-do. The vascular plants of each uninhabited islets were summarized as Beomseom 159 taxa, Chagwi-do 136 taxa, Daryeo-do 81 taxa, Hyeongje-do 61 taxa, Jigwi-do 39 taxa, Munseom 147 taxa, Ran-do 58 taxa, Saeseom 65 taxa, Seogeondo 60 taxa, Seopseom 183 taxa and Wa-do 46 taxa. Floristic richness was in order analyzed to be Seogeon-do 28.62, Ran-do 19.24, Daryeo-do 18.53, Wa-do 16.42, Munseom 16.14, Hyeongje-do 14.76, Seopseom 13.32, Beomseom 13.24, Chagwi-do 6.15, Saeseom 5.86 and Jigwi-do 2.51. Life form spectrum was surveyed to H-$D_5$-$R_4$-e; hemieryptophyte(H) 26.8%, not production seeds($D_5$) 54.4%, clonal growth by stolons and struck roots($R_4$) 46.9% and erect form(e) 30.3%. According to the life form spectrum hemieryptophyte dominated high portions, which suggests islet in jeju-do has hemieryptophytic climate and similar to middle parts in Korean Peninsular. However, were noticed by that it has more therophytes. As a result, Partially shows the characteristics change from the temperate climate to the warm temperate climate or a semitropical climate by a climatic change.

This article examines the utilization of e-resources Modibbo Adama University of Technology, (MAUTech) Yola under the auspices of the central library, the Ibrahim Babangida Library. Academics and students are primary users of information resources of any library, hence, their responses towards the utilization of e-resources in the institution have been critically considered in this study. A Mixed method research Design was adopted for the study. A case study approach was employed. The Technology Acceptance Model (TAM) and Diffusion of Innovation (DoI) theories were used to develop the conceptual framework of this paper. Questionnaires were used as data gathering tools. Academics and students acted as participants. Major findings are lack of sufficient Internet access for academics and students and lack of training and awareness campaigns. Conclusion has shown that e-resources did not impact research and teaching of academics in MAUTech, Yola.

O presente estudo tem como objetivo principal analisar a influência de vocabulários de origem africana em uso no português brasileiro(PB). A fim disso, observamos os tipos e as características das línguas africanas. E ainda, para compreender a situação atual de uso desses termos no Brasil, apresentamos um panorama do registro dos vocábulos de origem africana no PB, e organizamos os vocabulários em três categorias, especialmente, nos registros dos séculos XIX e XX. Em primeiro, a categoria 1 pode ser usada em qualquer interação social, contrastando com as outras duas categorias. Em segundo, a categoria 2 é constuída de termos informais, de uso coloquial que, eventualmente, dependendo da situação, são substituídos por outras. Por último, a categoria 3 é de termos marcadamente informais, de uso restrito. Através disso, comparamos os registros anteriores com os dados obtidos da nossa pesquisa. Com os resultados, podemos reconhecer a estabilidade e o dinamismo do uso desses termos hoje no PB.

진우도 해빈에서 2005년 11월과 2006년 5월의 2회에 걸쳐서 표층퇴적물을 채취하여 퇴적물의 조직변수를 분석하였다. 2005년 11월에 비하여 2006년 5월에는 진우도 서쪽 해빈의 최빈값은 $3.0\phi$(i.e., 0.125 mm)로 변화가 거의 없었으나, 동쪽 해빈에서는 최빈값$3.0\phi$(i.e., 0.125 mm)의 함량이 대폭 감소하고 $2.5\phi$(i.e., 0.177 mm)가 절대적으로 우세한 조립화 경향이 발생하였다. 마찬가지로 표층퇴적물 평균 입도는 서쪽 해빈에서는 두 조사의 차이가 거의 미약하지만, 동쪽 해빈의 평균입도는 증가되어 조립화된 특징을 반영한다. 이러한 조립화는 2006년 5월에 진우도의 동쪽 해빈의 표층퇴적물에서 상대적으로 양의 값으로 변화된 왜도 경향과 일치한다. 결과적으로 2005년 겨울을 지나면서 진우도의 표층퇴적물은 서쪽 해빈은 큰 변화를 보이지 않는 반면에 동쪽 해빈은 $3.0\phi$(i.e., 0.125 mm)의 세립 사질퇴적물이 제거되는 현저한 조립화 경향이 나타난 것이다. 이와 같은 변화는 낙동강 하구역에 하계동안 증가된 강수량과 낙동강 방출량 그리고 동계동안 우세한 파랑 그리고 조석의 영향 등이 복합적으로 작용하여 진우도 서쪽 해빈과 동쪽 해빈의 표층퇴적물에 영향을 주는 수리학적 조건과 퇴적물의 공급/제거가 다르기 때문이다.

This study was carried out forecasting of pollution inflow of the Small Mountainous Catchment, namely; Seolma-cheon experimental catchment. Pollutographs of DO, BOD, T-N, Conductivity, T-p, pH. COD, SS from this catchment were obtained from in-situ data of total ten events using QUAL2E-PULS model. From the analysis results, between up stream(Sabang-bridge) and down stream (Memorial-bridge, outlet) obtained relation formula of water quality component. Determination coefficient of relation formula, Conductivity, COD, BOD, DO, pH, T-N, T-P, and SS showed high relation of $0.87{\sim}0.99$. The increases of DO, BOD, COD, and pH concentration of Memorial-bridge were associated with pollution inflow by road building far 2.25km from Sabang-bridge to down stream. The analysis results of QUAL2E-PULS simulation and up/down stream relation formula, pollution amounts of DO, BOD, COD and pH increased at Memorial-bridge and pollution source site. Therefore, pollution inflow can be forecasted exactly by up/down stream relation formula at pollution source site.

To determine geographical patterns of natural parasite infections among wild rodents, a total of 46 wild rodents from 3 different localities in northern Gangwon-do (Province), Korea were examined for intestinal parasite infections. Along with nematodes such as hookworms and Syphacia spp., Plagiorchis muris (2 specimens) (Trematoda) were collected from striped field mice, Apodemus agrarius. In a Korean wood mouse, Apodemus peninsulae, the overall nematode infections were similar to A. agrarius, but an adult worm of Echinostoma hortense (Trematoda) was collected. In addition, 2 species of cestodes, i.e., Hymenolepis nana and Hymenolepis diminuta, were collected from A. agrarius. Through this survey, A. agrarius and A. peninsule were confirmed as the natural definite hosts for zoonotic intestinal helminths, i.e., P. muris, E. hortense, H. nana, and H. diminuta, in northern Gangwon-do, Korea. Considering increased leisure activities around these areas, seasonal and further comprehensive surveys on wild rodents seem to be needed to prevent zoonotic parasite infections.
