Anisakiasis refers to parasitic infestation by nematode larvae that belongs to the subfamily Anisakinae, and this condition is seen in people who eat inadequately prepared or raw salt-water fish. While gastric anisakiasis is commonly diagnosed by endoscopic technique, intestinal anisakiasis is rare because it is less common and the clinical and radiologic features are poorly understood. The authors report a case of human anisakiasis involving the ileocecal valve in 62-year-old man who had the history of eating raw cuttlefish.

Most reinforcements in concrete are constructed by steel. Corrosion of reinforcement is the main cause of damage and early failure of reinforced concrete structures. The corrosion is mainly progressed by the chloride ingress. In general, chloride in concrete can be discriminated by two components, total chloride and free chloride. This paper provides a testing method on the coefficient of chloride diffusion in concrete and the relationship between total chloride and free chloride in concrete for the composition of predicting model on diffusion rate of chloride. In order to complete this predicting model, this study will use chloride penetration characteristic, diffusion coefficient, and experiment of color change on silver nitrate solution. This predicting model is going to help that grasp special quality on salt content inclusion of concrete structure that is exposed in chloride environment. Accurate predicting model can be effectively used not only in selecting of repair time but also in preventing from various deteriorations.

In order to product and develop questionnaire which can assess the schizotypal personality by model of criteria in DSM-Ⅲ-R, it was presented following question in this study. First, for the validation and manufacture of scale and sub-subscale that assess overall feature, nine characteristics of the schizotypal personality disorder, this study was concerned with validity, reliability and factor-analysis results of schizotypal personality questionnaire. Second, we would by present how schizotypal personality disorder trend is connected with trait-anxiety, hopelessness and self-concept. Also the difference is compared with. Finally, 396(male 216 Ss/53,8%, female 180 Ss/45.5%) college students with mean age 21.2 years were sampled. Raine(1991)'s schizotypal personality questionnaire(SPQ) which assess nine characterisitics of schizotypal personality disorder in DSM-Ⅲ-R was translated and used. In this results, Raine's schizotypal personality questionnaire was appeared to have high internal validity, split-half reliability and test-retest reliability. Also, 6 factors were affirmed by empirical confirmation through factor-analysis. 6 factors have been very reliable internal validity that ranges from .78 to .83. In these 6 factors, idea of reference, odd or eccentric behavior and odd speech were corresponded to the category model after DSM-Ⅲ-R in Raine's scale. 'Cognitive, perceptive' dimension was centered of factor 1, 'Emotive, affective' dimension was centered of factor 2, social anxiety and constricted affect were constituted to 2nd factor. No close friends, schizoid trend and suspiciousness of schizotypal characteristics were constituted to 3rd factor by 'interpersonal relationship' dimension. These empirical outcomes which confirmed through factor-analysis were very valid and connected much to Raine's scale which assessed schizotypal personality disorder, thus possibility of development and manufacture of schizotypal personality disorder scale through item revision was lighten. In 2nd study the higher schizotypal personality disorder trend, trait-anxiety and hoplessness were higher. But on the contrary, self-concept was lower. The group of high score in schizotypal personality questionnaire had more trait-anxiety and hopelessness than the group of low score in schizotypal personality questionnaire. Contrastly, positive self-concept was high in the group of low score. Also the most predictable variable to the trait-anxiety was factor 2, predictable power R²of factor 2 was 29.1%. To the hopelessness, factor 2 was the most powerful predictable variable. Predictable power of factor 2 was 11.2%, also. In self-concept, factor 2 explained 20.8% of self-concept, thus it was presented that factor 2 had the most powerful explanatory quantity. In these consequences, the factors which have meaningful connection to the trait-anxiety, hopelessness and low self-concept within 6 factors were really factor 2, 3, 1. Among these factors, "Emotive' feature of factor 2 including social anxiety and constricted affect have the most effect on trait-anxiety, hopelessness and self-concept. And next to factor 2, the isolated interpersonal relation which include no close friends and schizoid trend was some influential variable. Also peculiar, unusual preceptual experience, eccentric belief and magical thinking had some effect though small. The college students who had strong schizotypal personality trend had more social anxiety and more constricted emotional empathic ability, less self-expression, less social skill than common college sudents. These elements threaten, interrupt and retard identity establishment and intimacy-seeking which are important developmental tasks within this period. These experiences is accepted to ego-dystonic to schizotypal college students who have some or moderate reality testing, adaptive ability. Moreover, These peoples would feel locus of contol externally, not internally and would have more control-failure experiences. All these elemets elevate anxiety level, give rise to low self-concept and low expectation to the future. These outcomes all confirmed questions which presented in this study.

A Study on the Optimum Material Mix Design for Vegetation Shotcrete Using Mineral Additive

Yang, Eun Ik,Choi, So Yeong,Lee, Gyung Jong,Choi, Yoon Suk Trans Tech Publications, Ltd. 2017 Key Engineering Materials Vol.744 No.-

<P>In this paper, the material characteristics of field applied green slope soil for the development of vegetation shotcrete using mineral additive are evaluated. And, the effect of the moisture content of fertilizer on properties of the shotcrete soil using the mineral additives are investigated. From the results, it was found that when the compaction level increase, soil hardness and soil strength are increased. Moreover, after a certain level of consolidation is proceeded, soil hardness and soil strength are not affected by ages. However, in order to ensure slope stability, the cohesion of the field applied soil should be improved. When the mineral additive is mixed as a green shotcrete soil materials, it could be attributed to the increment of adhesion between green slope soil and slope face. And, when the moisture content of fertilizer increases, the soil hardness and soil strength is decreased. The moisture content of fertilizer increases, shrinkage decrease at early ages, however, shrinkage increased with ages. The optimum moisture content of fertilizer was about 60% from the view point of shrinkage and soil hardness of green shotcrete soil.</P>

Stereoisomer-specific ginsenoside 20(S)-Rg3 reverses replicative senescence of human diploid fibroblasts via Akt-mTOR-Sirtuin signaling

Yang, Kyeong-Eun,Jang, Hyun-Jin,Hwang, In-Hu,Hong, Eun Mi,Lee, Min-Goo,Lee, Soon,Jang, Ik-Soon,Choi, Jong-Soon The Korean Society of Ginseng 2020 Journal of Ginseng Research Vol.44 No.2

Background: The replicative senescence of human dermal fibroblasts (HDFs) is accompanied by growth arrest. In our previous study, the treatment of senescent HDFs with Rg3(S) lowered the intrinsic reactive oxygen species (ROS) levels and reversed cellular senescence by inducing peroxiredoxin-3, an antioxidant enzyme. However, the signaling pathways involved in Rg3(S)-induced senescence reversal in HDFs and the relatedness of the stereoisomer Rg3(R) in corresponding signaling pathways are not known yet. Methods: We performed senescence-associated β-galactosidase and cell cycle assays in Rg3(S)-treated senescent HDFs. The levels of ROS, adenosine triphosphate (ATP), and cyclic adenosine monophosphate (cAMP) as well as the mitochondrial DNA copy number, nicotinamide adenine dinucleotide (NAD)⁺/1,4-dihydronicotinamide adenine dinucleotide (NADH) ratio, and NAD-dependent sirtuins expression were measured and compared among young, old, and Rg3(S)-pretreated old HDFs. Major signaling pathways of phosphatidylinositol 3-kinase/Akt, 5' adenosine monophosphate-activated protein kinase (AMPK), and sirtuin 1/3, including cell cycle regulatory proteins, were examined by immunoblot analysis. Results: Ginsenoside Rg3(S) reversed the replicative senescence of HDFs by restoring the ATP level and NAD⁺/NADH ratio in downregulated senescent HDFs. Rg3(S) recovered directly the cellular levels of ROS and the NAD⁺/NADH ratio in young HDFs inactivated by rotenone. Rg3(S) mainly downregulated phosphatidylinositol 3-kinase/Akt through the inhibition of mTOR by cell cycle regulators like p53/p21 in senescent HDFs, whereas Rg3(R) did not alter the corresponding signaling pathways. Rg3(S)-activated sirtuin 3/PGC1α to stimulate mitochondrial biogenesis. Conclusion: Cellular molecular analysis suggests that Rg3(S) specifically reverses the replicative senescence of HDFs by modulating Akt-mTOR-sirtuin signaling to promote the biogenesis of mitochondria.
