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

Mannque Rho 한국물리학회 2016 새물리 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?

American Literary Canon of Pre-Columbian Era in Elizabeth Chesley Baity’s Americans before Columbus

( Rho¸ Heongyun ) 동국대학교 영어권문화연구소 2017 영어권문화연구 Vol.10 No.2

This paper analyzes the American canon of pre-Columbian era in Elizabeth Baity’s Americans before Columbus, a winner of Newbery Honor prize in 1952. As Raymond Williams pinpoints “the selective tradition” as one of the essential characteristics in canonical texts, Baity’s “selective” perspectives towards pre-Columbian Indians have been influential in making stereotypes of Indians. Devon Mihesuah elaborates twenty five stereotypes: “Indians are all alike”; “Indians were conquered because they were inferior”; “Indians have no religion”; “Indians are a vanished race” etc. On one hand, Baity has recorded meticulously the past histories of the Americas in pre-Columbian era with pictures and illustrations. On the other hand, she “selectively” agreed with the discourses in American studies: Crosby’s ecological imperialism; the settlement, not colonization, theory of the Americas; Columbus as a hero rather than bullies; the primitiveness of the Indians vs the civilization of Euro-Americans. The main audiences of Baity’s book are children attending public schools. Once familiar with the stereotypes of Indians in their early age, they will accept without doubt similar images of Indians from such college textbooks as American Roots and A New Introduction to American Studies they read within classrooms. What is missing in Baity’s book is the discourses to bridge the two big paradigms, America before Columbus and America after Columbus, from complementary standards. The addition to the missing part will keep the Newbery Honor book free from the polemics of political correctness.

항공용 안테나 하이브리드 모노펄스 레이다 시스템을 이용하여 지상 이동표적 탐지 시, 표적의 방위각 정확도는 시스템 내 채널 간 위상 불균형에 따른 모노펄스 기울기 추정 정확도에 지배적으로 영향을 받는다. 본 논문에서는 안테나와 180도 하이브리드의 물리적 길이 차이에 의한 위상 불균형을 효과적으로 보상할 수 있는 방법을 제안 하였다. 비행시험을 통하여 제안된 방법의 성능을 검증한 결과, 보상 전보다 유의한 성능개선 효과를 확인할 수 있었다. The accuracy of extracting the azimuth angle of a target is significantly affected by the error in the mono-pulse ratio of the air-borne antenna hybrid mono-pulse Radar system. This error is strongly induced by the phase imbalance between the channels of the system. In this paper, a method is proposed for effectively calibrating the phase imbalance caused by physical differences between the RF channels from the antenna to the 180° hybrid. Through a flight test, it was confirmed that the accuracy of the azimuth angle of the target is improved by using the proposed method.

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 The Korean Society of Fisheries and Aquatic Scienc 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.

A Study on the Use of Preferable Textual Enhancement Techniques From L2 Learners in the Movie Before Sunset

Rho Yoon-Ah(Yoon-Ah Rho) 영상영어교육학회 2022 영상영어교육 (STEM journal) Vol.23 No.2

This study aims to examine whether textual enhancement (TE) saliency leads to second-language learning and to determine whether different types of TE influence second-language learning. The study invited three advanced level college students as participants using material from the movie Before Sunset (Linklater, 2004). In this case study, Participant A used an underline format, Participant B used a story map, and Participant C used a color-code format. They each had four tests (showing a TE strategy, form recalling, content remembering, and language completion rate). The results showed that each participant successfully used their individual TE strategy. Since Participant A primarily focused on language, his second test results were good, but his scores declined two and four weeks later. Participant C primarily paid attention to content; she performed well in a test relevant to the content but was the worst in language tests. Participant B performed the best across all tests because she focused on both language and content. This study suggests that attention is necessary for second-language learning, but that attention should be paid to form and meaning simultaneously. When it combines form and meaning, TE will be effective in secondlanguage learning.

섬유질 분해능이 향상된 새로운 Aspergillus 균주를 개발하기 위하여, A. awamori, A. usamii, A. oryzae 등의 균주간의 핵전이를 통하여 종간잡종을 얻어내었다. 이들 상호간의 안정된 종간잡종은 원형질체 융합법에 의해서는 전혀 이루어지지 않은 데 반하여, 핵전이에 의한 종간잡종 형성 빈도는 2×10 exp(-5)-7× exp(-4)으로 나타났다. 분리된 잡종들의 효소활성도를 분석해 본 결과, 10 개의 균주에서 cellulase, xylanase, amylase, β-xylosidase, 그리고 β-glucosidase 중 일부 또는 모든 효소 활성이 모균주보다 2배 이상까지 높은 것으로 나타났다. 또한, 전기영동 및 isoelectric focusing에 의하여 일부 잡종들의 동위효소 양상이 모균주의 어느 쪽과도 일치하지 않음을 확인하였다. 포자의 크기 및 DNA 함량을 측정한 결과로 미루어 보아, 그들의 핵형은 대부분 배수체 또는 반수체에 가까운 이수체일 것으로 예측되었다. 본 연구의 결과, Aspergillus 속 균류에서 유연관계가 비교적 먼 종들 사이의 잡종형성을 통하여 새로운 균주를 개발하는 데 있어서 핵전이법이 원형질체 융합법보다 훨씬 더 효과적임이 밝혀졌다. Interspecific hybrids between the Aspergillus spp., A. awamori, A. usamii and A. oryzae, were obtained by nuclear transfer technique. Nuclei isolated from an auxotrophic mutant strain were transferred into the protoplasts of a recipient strain of different species. The frequency of interspecific hybrid formation by nuclear transfer was 2×10 exp (-5) - 7× 10 exp (-4). In contrast, no interspecific hybrid was isolated by protoplast fusion. Among the hybrids tested, 10 strains showed increased activity of some or all components of cellulases, xylanases and amylase up to more than two times. Isozyme patterns of the hybrids were analyzed by polyacrylamide gel electrophoresis and isoelectric focusing followed by activity staining, which showed that some of the hybrids have isozyme patterns unidentical to either of the two parents. By measuring the DNA contents and the sizes of the conidia, the karyotypes of the hybrids were estimated to be aneuploid near to haploid, diploid or triploid. It was concluded that the nuclear transfer technique is much more efficient in the formation of interspecific hybrids than protoplast fusion, and is very useful for the improvement of Aspergillus strains.

Effects of the Low Power He-Ne IR Laser Treatment on the Liver Damage Induced with CCl₄in Rats

Rho, Min-Hee,Kim, Jai-Young THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 2004 Journal of biomedical laboratory sciences Vol.10 No.3

This study was investigated the effects of the lower power He-Ne IR laser treatment on the changes of blood biochemical components in the rat liver damaged by the carbon tetrachloride (CCl₄). The twenty one Sprague-Dawley adult male rats weights (260f18.6 g) were designed to the three groups: one control group and two experimental groups, the experimental groups were divided into the CCl₄-treated groups and the laser therapy group (CCl₄+ Laser). The experimental groups were injected twice with CCl₄ (1.0ml/kg body weight) intraperitoneal for two days. Each group was sacrificed after two weeks irradiated with the lower power He-Ne IR laser for ten minutes per every day. The activity of alanine aminotransferase (ALT), lactic dehydrogenase (LDH), alkaline phosphatase (ALP) and the concentration of serum glucose treated with He-Ne IR laser groups was significantly decreased to the conrtol (treated with carbon CCl₄) group. The activity of aspartate aminotransferase (AST) was decreased in the laser group but not sigdicantly, the concentration of the serum cholesterol in the laser group was significantly increased comparing with the control and case control groups. In conclusion, the effect of the lower power He-Ne IR laser treatment is believed to be a possible protective effects for CCl₄, induced acute hepatotoxicity in rats.

Sectoral Divergence of Industrial Catch‐Up in China's Loosely Coupled System: A Comparative Study of FPD and IC Manufacturing Industries

Rho Sungho,Kim Yongshin 인하대학교 국제관계연구소 2021 Pacific Focus Vol.36 No.3

The flat panel display (FPD) and integrated circuit (IC) manufacturing industries have similar intrinsic characteristics in terms of their technology. The Chinese central government also makes significant efforts to nurture them both as core industries of the electronics sector. However, the level of industrial catch-up in the two sectors across recent years has varied greatly. What drives the divergent patterns of industrial catch-up in FPD and IC manufacturing in China? This paper analyzes the divergent patterns of industrial catch-up in FPD and IC manufacturing by examining the configurational effects of three main components: the central state's promotion of industry, technology regimes and market conditions, and corporate governance. The different sets of configurations explain why innovation occurs in some industries and not in others within China's loosely coupled system. This study argues that different arrangements in industrial policy, combined with technical regimes, market conditions, and corporate governance triggered a virtuous cycle in which organizational capabilities are strengthened in FPD industry, while the reverse occurs in the IC manufacturing industry. Incorporating configurational effects enriches the evolutionary perspective on catch-up and allows for a comparison between the catch-up conditions across multiple levels.
