        Probing the Source of the Proton Mass by "Unbreaking" Scale-Chiral Symmetry

        Mannque,Rho 한국물리학회 2016 New Physics: Sae Mulli Vol.66 No.12

        I describe a possible scenario for the origin of the proton mass in terms of the Cheshire Cat, half-skyrmions, topology change and interplay between hidden chiral-scale symmetry and induced local symmetry. This differs from the standard constituent-quark scenario. As the baryonic matter density is increased toward the vector manifestation (VM) fixed-point at which the $\rho$ mass is to vanish, the effective in-medium mass ratio $m^*_\rho/m^*_N$ tends to zero proportionally to $g^*_\rho$, where $g^*_\rho$ is the in-medium hidden gauge coupling constant. I develop the thesis that the intricacy involved in the mass generation can be decoded from experiments at RIB accelerators and data on massive compact stars.

        Forensic Pathology in Crimes of Violence

        Rho,Yong-Myun 大韓法醫學會 1986 대한법의학회지 Vol.10 No.1

        法醫病理醫師들이 犯罪搜査에 있어 重要한 役割을 한다. 一般病理醫師들은 解剖所見에만 置重하지만 法醫病理醫師들은 剖檢所見을 事件搜査에 있어 不過部分的 資料로 利用한다. 같은 所見이라도 지니는 環境에 따라 그 解釋이 달라지기 때문이다. 現場檢査, 環境分析, 毒物檢査 등은 法醫搜査에서 없어서는 안되는 要素들이다. 法醫病理醫師가 남이 다치지 않은 屍體를 처음부터 스스로 檢査한다는 것이 얼마나 重要한 일인지를 例를 들어 說明하였다. 自然疾患과 强力犯罪와의 相互關係 特히 外傷이 比較的 輕한 境遇에 對하여 討論하였다. 훌륭한 法醫醫師가 되려면 于先 훌륭한 病理醫師여하 하지만 훌륭한 病理醫師가 반드시 훌륭한 法醫醫師일 수는 없다. 1) Yong-Myun Rho: Murder or suicide?

      • Effect of Recombinant Bovine Somatotropin on Growth of Olive Flounder, Paralichthys of olivaceus

        Rho,,Sum-Rho,Kim,,Pil-Youn,Lee,,Young-Don,Choi,,Kwang-Sik,Song,,Choon-Bok 한국양식학회 1999 韓國養殖學會誌 Vol.12 No.2

        The recombinant bovine somatotropin (rBST) was administered to the oliver flounder, Paralichthys olivaceus, to know the effects and optimal administration frequency and dosage of the hormone. The experiment was conducted with three different treatment groups (A, B and C) designated based on the duration and administration frequency of rBST and one control (D) from April 14, 1996 to March 16, 1997. The fish of hormone treated groups grew 7.86 to 10.07% (47.45 to 60.75 g in weight) better than the control at the end of the experiment (P<0.05). No significant differences in their growth were detected among treatment groups. The distinct growth improvement was recognized four weeks after completion of the first four hormone administration. When considering water temperatures measured from the experimental tanks, the effect of rBST on the flounder was greater during the period showing relatively lower temperature. The survival rates were higher in treatment groups than in the control, revealing 98.3% (A), 98.4% (B), 97.7% (C) and 93.1% (D) during the first stage of culture; 92.7% (A), 91.3% (B), 86.7% (C) and 80.0% (D) during the second stage of culture.

        Enterococcus faecium FC-K Derived from Kimchi Is a Probiotic Strain That Shows Anti-Allergic Activity

        Rho,,Man-Kwang,Kim,,Young-Eun,Rho,,Hyun-In,Kim,,Tae-Rahk,Kim,,Yoon-Bum,Sung,,Won-Kyung,Kim,,Tae-Woo,Kim,,Dae-Ok,Kang,,Hee The Korean Society for Microbiology and Biotechnol 2017 Journal of microbiology and biotechnology Vol.27 No.6

        A rise in the occurrence of allergic diseases is attributed to the dysregulated balance of type 1/type 2 immunity, where type 2 T-helper (Th2) cells predominate over type 1 T-helper (Th1) cells, leading to an abnormally increased production of IgE in response to unharmful antigens. Kimchi, a traditional Korean fermented food, is a rich source of beneficial lactic acid bacteria. In this study, we investigated the ability of Enterococcus faecium FC-K derived from kimchi to induce type I immunity in the presence of Th2 polarizing conditions in vitro and in vivo. Stimulation of mouse peritoneal macrophages with E. faecium FC-K induced the production of tumor necrosis factor alpha, interleukin (IL)-6, and IL-12. Under the in vitro Th2 conditions in which splenic T cells were activated in the presence of IL-4, E. faecium FC-K enhanced the ability of T cells to produce interferon $(IFN)-{\gamma}$. Using the ovalbumin (OVA)-induced allergy model, male BALB/c mice receiving E. faecium FC-K reduced the serum level of total IgE, but not that of OVA-specific IgE. Furthermore, the population of activated splenic B cells during OVA immunization was decreased in E. faecium FC-K-treated mice, accounting for a reduction of total IgE in the serum. Restimulating splenocytes from OVA-immunized mice with OVA ex vivo resulted in an increased production of $IFN-{\gamma}$, with no effect on IL-4, in E. faecium FC-K-treated mice. These observations provide the evidence that E. faecium FC-K can be a beneficial probiotic strain that can modulate the Th2-mediated pathologic response.

        A Case of Glomeruloid Hemangioma in a Patient with Multicentric Castleman`s Disease

        Rho,,Nark,Kyoung,Lee,,Eil,Soo,Park,,Sang,Jin,Lee,,Dong,Youn The Korean Dermatological Association 2002 Annals of Dermatology Vol.14 No.4

        Glomeruloid hemangioma is a histologically distinctive cutaneous angioma which is rarely described in patients with POEMS (polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes) syndrome and multicentric Castleman's disease. We report an additional case of glomeruloid hemangioma in a 30-year-old Korean woman with multicentric Castleman's disease showing features of POEMS syndrome. Histopathology revealed multiple dermal dilated vascular spaces composed of a conglomerate of capillaries, resulting in structures reminiscent of renal glomeruli. Periodic acid-Schiff-positive and diastase-resistant eosinophilic globules were found within the cytoplasm of vacuolated endothelial cells. The endothelial cells lining the capillary loops showed positive immunostaining for factor Ⅷ-related antigen and CD31.

        Protective Effect of Acanthopanax senticosus Extract on Alloxan-induced β-cell Damage

        Rho,,Hye-Won,Lee,,Ji-Hyun,Kim,,Jong-Suk,Kim,,Hyung-Rho,Park,,Byung-Hyun,Park,,Jin-Woo The Korean Society of Food Science and Nutrition 2005 Preventive Nutrition and Food Science Vol.10 No.1

        The protective effect of Acanthopanax senticosus (AS) extract on alloxan-induced pancreatic β-cell damage was investigated in HIT T-15 cells, a Syrian hamster pancreatic β-cell line. Alloxan caused the pancreatic β-cell damage through the generation of reactive oxygen free radicals, increased DNA fragmentation, and decreased cellular NAD/sup +/ levels. The β-cell damage was significantly prevented by the pretreatment with water soluble extract of AS roots. These results suggest that the protective effect of AS extract, on alloxan-induced β-cell damage, is primarily due to the inhibition of the generation of reactive oxygen free radical species (ROS) by alloxan.

        Methyl ethyl ketone과 물 이성분계 혼합물의 압력변환 증류공정에 대한 전산모사 및 최적화에 대한 연구

        노상균(Rho, Sang-Gyun), 노재현(Rho, Jae-Hyun), 조정호(Cho, Jung-Ho) 한국산학기술학회 2012 한국산학기술학회논문지 Vol.13 No.8

        본 연구에서는 methyl ethyl ketone (MEK)와 물의 이성분계 공비 혼합물의 공비조성이 압력에 따라서 민감 하게 변하는 현상을 이용하여 압력변환 증류(pressure-swing distillation; PSD)공정을 통해서 순도가 99.9mole% 이상의 MEK를 분리해 내기 위한 전산모사 및 공정 최적화를 수행하였다. 전산모사를 위하여 상용성 화학공정 모사기인 Invensys사의 PRO/II with PROVISION 9.1을 활용하였고, 열역학 모델식으로는 Wilson 액체 활동도계수 모델식을 활 용하였다. PSD 공정은 저압 및 고압의 증류탑 2기의 증류탑 배열을 사용하는데 저압 증류탑을 전단에 두는 저압-고 압 증류탑 배열과 저압 증류탑을 후단에 두는 고압-저압 증류탑 배열로 분류할 수 있다. 본 연구에서는 각각의 배열 에 대한 증류탑 환류비와 원료 주입단의 위치를 조절변수로 하여 총 재비기의 heat duty의 합을 최소화시킨 후 두 공 정배열을 서로 비교하였다. In this study, modeling and optimization works were completed for the separation of 99.9 mol% of methyl ethyl ketone from water through a pressure-swing distillation process since the azeotropic composition varies very sensitively with the change of system pressure. PRO/II with PROVISION release 9.1 was used for the computer simulation and Wilson activity coefficient model was chosen as a modeling equation. A pressure-swing distillation process can be classified into a low-high pressure columns configuration and a high-low pressure columns configuration. In this work, each configurations were optimized for the minimization of steam consumptions, respectively and were compared.

        In case of using fly ash as some substitutes of cement, it is possible for us to improve durability through the improvement of liquidity and enhancement of water-tightness according to the effect by the ball bearing of mortar and concrete. It is widely used because it is very effective of decreasing the crack of concrete and improving the long-time strength through the decrease of heat of hydration, etc. However, it is severe in quality variation by the use of reckless substitutes, and it has large congelation retard, so there are disadvantages like the deterioration of performance on mortar and concrete due to the decrease of early strength. Accordingly, as a result of analyzing the strength, characteristics of congelation, and heat of hydration, etc. in order to examine the engineering properties of mortar using fly ash with high fineness in this study, this researcher could get excellent performance on the improvement of early strength and characteristics of heat of hydration according to the acceleration of congelation by the high fineness.
