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.

HISIM모형의 개발에 관한 연구

李仁遠,朴魯峰,朴鍾日 弘益大學校 科學技術硏究所 2005 科學技術硏究論文集 Vol.16 No.-

The development in the information technology area has enabled drivers to use the ATIS (Advanced Traveller Information System) more easily by establishing ubiquitous environment where users may access the network at any place and time. The ATIS is the central part of the ITS (Intelligent Transportation System). The travel time of a transportation network at rush hours, however, has been calculated based on a simple proportional function between the traffic volume and travel time. This simplified method has been adopted in the trip assignment model for technical reasons resulting in the actual traffic flow at rush hours not being properly reflected. Therefore, it has fundamental limits in terms of the ever changing traffic conditions and short term prediction. In addition, the static trip assignment, which is mainly used in the trip assignment of traffic flow, does not allow any time-dependent changes. Under this assumption, the static trip assignment may predict relatively long-term average traffic flow, but cannot describe such characteristics as changing in a time-dependent manner. This assumption also supposes that the traffic flow has a uniform distribution in the applied area, which is regarded as another flaw of the static assignment method. As a result, various dynamic methods analyzing traffic conditions of a transportation network have been recently developed. Against this background, the objectives of this study are as follows: To develop HISIM (Hong Ik SIMulation) model, apply the travel time calculation formula developed based on the previous BPR formula and Queueing theory to this model, and present values and limits of each model by simulating in the imaginary network and comparatively analyzing its results.

안승섭,박노삼,이수식,이관영,박상현 한국환경과학회 2000 한국환경과학회지 Vol.9 No.5

In this study, the removal possibility of nutrients of T-P, NH_3-N, NO_3-N, and T-N is examined through a positive experimental study using submerged biofilter of media packing channel method. From the analysis of nutrients removal efficiency for each run of the collected sample, following results are obtained. Firstly, the result of N/P surveying for inflow shows serious value that excess the limit value of 20 as the values are in the range of 12.0∼42.7 and the average is 25.73. Secondly, the highest concentration of the incoming NH_3-N reaches double of the standard since the concentrations of NH_3-N, and NO_3-N for inflow shows 0.06㎎/ℓ , and 2.5∼3.8㎎/ℓ respectively, and the average removal rate which passed the submerged biofilter adopted in this study is a satisfactory level. Next, the average removal rate of T-P of 51.5% shows the possibility of entrophication removal since the removal rate of T-P of 66.8∼68.8% in relative low temperature period of RUN 1∼2 appeared higher than in RUN 3∼6, and T-N shows relatively poor result with the average removal rate of 34.1%. And it is known that the bigger BOD/P and BOD/N are, the more removal rate increases from the examination result of the relation between BOD/P and BOD/N, and the treatment water T-P and T-N to decide the relation with the concentration of organic matters, and thought that the appropriate proportion is necessary for effective removal of nitrogen and phosphorus.

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.
