A Postmodern Reading of Ron Hansen’s The Assassination of Jesse James by the Coward Robert Ford

최동오 ( Choi Dongoh ) 한국현대영어영문학회 2021 현대영어영문학 Vol.65 No.4

This paper explores Ron Hansen's demystification of the Old West and its (demystification's) relation with the present culture of America that situates the discourse of the author in historical contexts. It focuses how Ron Hansen rereads past historical events related to Jesse James and his contemporaries and how his new understanding of the West functions as a strategy to grasp the historical continuity between past culture and present culture. This paper wants to suggest how we can position his discourse in our postmodern socio-literary contexts established historically. The representation of the West Ron Hansen presents is a historical discourse that rereads and rewrites part of American history. It resists the ideology of the existing discourses that have (re)constructed the mystification of the West and Jesse James; his method of demystification persistently decodes the structure of dominant socio-cultural discourses that are (re)produced, circulated and operated in American commercial culture, which has mystified the West and the Jesse James gang romantically. Ron Hansen's narrative is polysemous. It has a possibility that the text can be endlessly interpreted and reinterpreted by the reader. This possibility comes from Ron Hansen's literary ability of contextualizing the text that interrogates the mystification of the West with discursive practices that represent history.

해공복합운송 서비스품질이 포워더의 만족에 미치는 영향

최동오(Dongoh Choi) 한국항만경제학회 2012 韓國港灣經濟學會誌 Vol.28 No.2

세계화의 급속한 진전으로 인해 촉발된 물류활동의 글로벌화에 따라 새롭게 부각되고 있는 분야 중 하나인 해공복합운송은 해상운송의 경제성과 항공운송의 신속성을 통해 수송비용의 절감과 운송시간의 단축이란 목적을 달성하기 위하여 해상운송수단과 항공운송수단을 결합한 국제운송방식이다. 본 연구는 해공복합운송에서 포워더의 만족에 영향을 미치는 실제운송인의 서비스품질구성 요인을 규명하기 위하여 실제운송인을 이용해 본 경험이 있는 현직 포워더를 대상으로SERVPERF 모형을 이용하여 실증분석을 실시하였다. 통계적 검정결과 SERVPERF 모형에서 제시한 유형성, 신뢰성, 대응성, 확신성, 공감성 가운데 신뢰성, 대응성, 확신성, 유형성의 순서로 중요하다는 것이 검증되었으나 공감성은 통계적으로 유의하지 않게 나타났다. 이는 복합운송 산업의 특성에 따라 약속된 서비스를 신뢰할 수 있고, 정확하게 수행 가능한 능력으로 구성되는 요인인 신뢰성의 중요성이 나타난 결과라 할 수 있다. 그리고 기업이 고객에게 제공하고자 하는 개별적인 배려와 관심으로 구성되는 요인인 공감성의 경우 통계적으로 유의하지 않게 나타났는데, 이 또한 산업의 특성을 반영한 결과라고 할 수 있다. As the globalisation of corporate’s managemental environment, all parts of logistics such as procurement, production and sales are globalized. The ways of transportation in Korea and Japan, where are difficult to use land-transportation, are sea-transportation and air-transportation. Sea & air is a way of the international transportation which is combined by Sea and Air to reduce the transportation fee and shorten the delivery time. The main body of multimodal transportation service is the corporate, actual carrier who undertakes the actual transport. It is essential to establish service quality to maintain their going concern. In other words, the actual carrier has to emphasize the importance of service quality to forwarder tan any other business conditions. In this study, we examine the determinants of service quality for actual carrier in multimodal transportation. Through the multi-regression analysis based on SERVPERF by Cronin and Taylor (1992), we analyze the service quality dimensions of actual carrier. Also we examine the relations between the determinants and customer’s satisfaction. Using statistical hypothesis testing, the determinants of service quality are reliability, responsiveness, assurance, tangibles, and we could look into the factors which the actual carrier should control with priority.

최홍준(Hongjun Choi),손동오(Dongoh Son),김종면(Jongmyon Kim),김철홍(Cheolhong Kim) 한국콘텐츠학회 2015 한국콘텐츠학회논문지 Vol.15 No.7

최신 고성능 컴퓨팅 시스템에서는, 대용량 병렬 연산을 효과적으로 처리할 수 있는 GPU의 우수한 연산성능을 그래픽 처리 이외의 범용 작업에 활용하는 GPGPU 기술에 관한 연구가 활발하게 진행 중이다. 하지만 범용 응용프로그램의 특성이 GPU 구조에 최적화되어 있지 않기 때문에 범용 프로그램 수행 시 GPGPU는 GPU의 연산 자원을 효과적으로 활용하지 못하고 있다. 그러므로 본 논문에서는 GPGPU 기술을 사용하는 컴퓨팅 시스템의 성능을 보다 향상시킬 수 있는 GPU 연구에 대한 방향을 제시하고자 한다. 이를 위하여, 본 논문에서는 GPU 성능 저하 원인 분석을 수행한다. GPU 성능 저하 원인을 보다 명확하게 분류하고자 본 논문에서는 GPU 코어의 상태를 완전 활성화 상태, 불완전 활성화 상태, 유휴 상태, 메모리스톨 상태, 그리고 GPU 코어 스톨 상태 등 5가지로 정의하였다. 완전 활성화 상태를 제외한 모든 GPU 코어 상태들은 컴퓨팅 시스템의 성능 저하를 유발한다. 본 논문에서 성능 저하 원인을 찾고자 벤치마크 프로그램의 특성에 따라 각 GPU 코어 상태의 비율 변화를 측정하였다. 분석 결과에 따르면, 불완전 활성화 상태, 유휴 상태, 메모리 스톨 상태 그리고 GPU 코어 스톨 상태는 연산 자원 활용률 저하, 낮은 프로그램 병렬성, 높은 메모리 요청, 그리고 구조적 해저드에 의해 각각 유발된다. In recent high performance computing system, GPGPU has been widely used to process general-purpose applications as well as graphics applications, since GPU can provide optimized computational resources for massive parallel processing. Unfortunately, GPGPU doesn’t exploit computational resources on GPU in executing general-purpose applications fully, because the applications cannot be optimized to GPU architecture. Therefore, we provide GPU research guideline to improve the performance of computing systems using GPGPU. To accomplish this, we analyze the negative factors on GPU performance. In this paper, in order to clearly classify the cause of the negative factors on GPU performance, GPU core status are defined into 5 status: fully active status, partial active status, idle status, memory stall status and GPU core stall status. All status except fully active status cause performance degradation. We evaluate the ratio of each GPU core status depending on the characteristics of benchmarks to find specific reasons which degrade the performance of GPU. According to our simulation results, partial active status, idle status, memory stall status and GPU core stall status are induced by computational resource underutilization problem, low parallelism, high memory requests, and structural hazard, respectively.

Cheon Yu,DongOh Choi,Yun-Seop Hwang 한국무역학회 2020 Journal of Korea trade Vol.24 No.8

Purpose – This is an exploratory study that aims to apply text mining techniques, which computationally extracts words from the large-scale text data, to legal documents to quantify trade claim contents and enables statistical analysis. Design/methodology – This is designed to verify the validity of the application of text mining techniques as a quantitative methodology for trade claim studies, that have relied mainly on a qualitative approach. The subjects are 81 cases of arbitration and court judgments from China published on the website of the UNCITRAL where the CISG was applied. Validation is performed by comparing the manually analyzed result with the automatically analyzed result. The manual analysis result is the cluster analysis wherein the researcher reads and codes the case. The automatic analysis result is an analysis applying text mining techniques to the result of the cluster analysis. Topic modeling and semantic network analysis are applied for the statistical approach. Findings – Results show that the results of cluster analysis and text mining results are consistent with each other and the internal validity is confirmed. And the degree centrality of words that play a key role in the topic is high as the between centrality of words that are useful for grasping the topic and the eigenvector centrality of the important words in the topic is high. This indicates that text mining techniques can be applied to research on content analysis of trade claims for statistical analysis. Originality/value – Firstly, the validity of the text mining technique in the study of trade claim cases is confirmed. Prior studies on trade claims have relied on traditional approach. Secondly, this study has an originality in that it is an attempt to quantitatively study the trade claim cases, whereas prior trade claim cases were mainly studied via qualitative methods. Lastly, this study shows that the use of the text mining can lower the barrier for acquiring information from a large amount of digitalized text.

비대면 공연으로의 전환과 마케팅 시사점 연구 : 서울 돈화문 국악당 사례를 중심으로

박선미(Park, Sunmi),최동오(Choi, Dongoh),유천(Yu, Cheon) 한국문화융합학회 2021 문화와 융합 Vol.43 No.2

본 연구는 온라인 공연의 비대면화가 관객개발에 미치는 영향에 관해 연구하고자 한다. 4차산업혁명의 시대에 초연결성은 사회, 경제, 문화 등 전 방위적으로 사회에 영향을 끼치며 세상을변화 시키고 있다. 공연예술은 공연자가 관객 앞에서 연기나 연주를 통해 작품을 만들어 가는무대예술임에도 불구하고 온라인의 발달로 비대면 공연이 활성화 되고 코로나19는 이와 같은상황을 가속화시켰다. 본 연구에서는 공연예술의 비대면 전환에 따른 관객개발 방안을 도출하기 위해 비대면 전환이관객에게 미친 영향을 살펴보았다. Wiggins(2004)가 제시한 MAO 모형을 활용해 공연 관람동기(Motivation), 관람능력(Ability), 관람기회(Opportunity)를 분류기준으로 사용하였고, 공연 관람후 관객반응의 차이를 비교하기 위해 관객만족도와 재방문의도를 사용하여 비대면 공연으로의전환이 미친 영향을 살펴보았다. 본 연구는 서울돈화문국악당의 대면 공연인 2019년과 비대면 공연인 2020년 관람객 조사 결과를 비교하여 분석하였다. 관람동기의 경우 비대면 공연시 공연과 예술가 비중이 대면 공연보다매우 크게 증가하였다. 둘째, 관람능력이 대면 공연에서는 공연 정보와 티켓의 획득, 공연장 위치의 파악과 이동할 수 있는 있는 능력을 의미하는 반면, 비대면 공연에서의 관람능력은 공연 정보의 획득, 비대면 관람을 위한 S/W와 H/W의 활용 및 기기의 확보 등을 고려해야 함이 나타났다. 세 번째, 관람기회는 관람접근으로 정의될 수 있는데 비대면 공연은 대면 공연에 비해 상대적으로폭 넓은 기회를 제공했다. 본 연구는 대면 공연과 비대면 공연의 관객반응을 실증 분석하여 차이를 규명하며, 잠재 관객의 개발을 위한 방법을 제안 하는데 의의를 갖는다. This paper aims to examine the impact of the non-contact performing arts contents on audience development. The Fourth Industrial Revolution has changed and influenced social, economic, and cultural sectors with high connectivity. Although the performing arts is a stage work that performers play music and act just in front of the audience, contactless performances have increased due to the online network’s development, and COVID-19 even accelerated this circumstance. In this paper, we study the impact of live stream concerts to find out effects from live to live streaming performances to develop audiences. To do so, we analyze from Wiggins’s(2004) research on the MAO model consisting of Motivation, Ability, and Opportunity, and a study on impacts of live stream concerts examined using audience satisfaction and revisit intention comparing with differences in audience reaction after watching performances. This paper examines Seoul Donhwamun Traditional Theater audience satisfaction research using a questionnaire from participants between 2019(live performance) and 2020(live streaming performance) concerts. The motivation to participate in live streaming concerts drastically increased on performance, and artists compared live concert gores. Secondly, the meaning of the ability to participate is somewhat different between live concerts and contactless concerts. The live concert audience should consider general information about a concert, ticket purchasing, venue location, and transportation, but the virtual audience needs to find concert information, media technology devices, and software. Finally, the opportunity can be defined as accessibility. In order words, live stream concerts reach an audience beyond physical boundaries. This research is a meaningful study that analyzes live and live streaming audience reactions, and it suggests ways to develop potential audiences.

유천(Cheon Yu),오유미(Yumi),최동오(Oh DongOh Choi) 한국기업교육학회 2021 기업교육과인재연구 Vol.23 No.4

본 연구는 캡스톤디자인 교과목 학습성과 영향요인을 규명하기 위한 것으로 지방 소재 국립대학교의 캡스톤디자인 교과목 중 링크플러스 사업단의 지원을 받은 139개의 팀을 대상으로 실증분석을 실시하였다. 종속변수는 캡스톤디자인 교과목 팀별 학습성과로 창의성, 완성도, 발전가능성이며 독립변수로는 팀규모, 팀커뮤니케이션, 팀티칭 여부, 정교수 여부, 지원규모, 공과대학 여부를 사용하였다. 또한 팀규모와 학습성과와의 역U자형 관계를 검증하기 위해 팀규모의 제곱항을 사용하였다. 분석방법으로는 다중회귀분석을 실시하였으며, 팀티칭의 조절효과를 별도로 검증하였다. 분석결과, 팀규모와 지원비 규모는 종합성과, 창의성, 완성도, 발전가능성에 모두 긍정적인 영향을 미치는 것으로 나타났다. 반면에 커뮤니케이션은 유의미한 영향관계가 나타나지 않았다. 교수자원의 경우에는 팀티칭은 창의성, 완성도, 발전가능성에 모두 긍정적인 영향을 미친 반면에 종합성과와는 유의미한 관계가 나타나지 않았으며, 정교수 여부는 발전가능성에만 정 (+)의 영향을 미치는 것으로 나타났다. 공대여부는 창의성에만 유의미한 영향을 미치는 것으로 나타났다. 팀규모와 학습성과와의 역U자형 관계는 성립되지 않았으며, 팀티칭은 팀규모와 학습성과와의 관계를 부(-)의 방향으로 조절하는 것으로 나타났다. 이러한 연구결과를 바탕으로 논의 및 시사점을 제시하였다. This study is an empirical approach designed to identify factors influencing the learning performance of capstone design classes. It analysis is conducted on 139 teams financially supported by the Linc+ among capstone design classes of one national university located in provincial areas. The dependent variable is learning performance for each team in the capstone design classes: creativity, completeness, and development potential. As independent variables, team size, team communication, dummy variable of team teaching, professor or associate/assistant professor, budget to support, and engineering college or not are used as independent variables. And the square term of team size is used to verify the inverse U-shaped relationship between team size and learning performance. As an analysis method, multiple regression analysis is performed, and the moderating effect of team teaching is separately verified. The analysis results are as follows. It was found that the team size and supporting budget had a positive effect on learning performance: creativity, completeness, and development potential. On the other hand, team communication did not show a significant influence relationship with learning performance. In the case of faculty resources, team teaching had a positive effect on creativity, completeness, and development potential, but it was found that dummy of a professor or not had a positive (+) effect only on development potential. An inverted U-shaped relationship between team size and learning outcomes was not established, and team teaching was found to moderate the relationship between team size and learning outcomes in a negative (-) direction. Based on these research results, discussions and implications are presented.

This study was conducted to evaluate effects of dietary multi-carbohydrases (MCS) in a lactating sow diet on productive performance and immune responses of sows and their piglets. A total of 12 sows (218.37 ± 5.5 kg BW; 2 parity) were randomly assigned to 2 dietary treatments: a diet based on corn-soybean meal (CON) and CON with 0.01% MCS. The MCS contained xylanase (2,700 units/g), β-glucanase (700 units/g), and cellulase (800 units/g). Sows were fed the dietary treatments for 28 days (weaning) after farrowing. Blood samples were collected from sows on d 0, 3, and 7 after farrowing and randomly selected 2 nursing piglets in each sow on d 3, 7, and 14 after birth. Measurements were productive performance of sows, frequency of diarrhea of piglets, and immune responses of sows and their piglets. Sows fed MCS had lower (p < 0.05) their body weight change than those fed CON. Piglets from sows fed MCS had higher (p < 0.05) average weight gain and body weight at weaning day and lower (p < 0.10) frequency of diarrhea than those from sows fed CON. Sows fed MCS had lower number of white blood cells (WBC) on d 3 (p < 0.05) and TGF-β1 on d 7 (p < 0.10) during lactation than those fed CON. Similarly, piglets from sows fed MCS had also lower (p < 0.05) number of WBC on d 3 and d 7 and TGF-β1 and C-reactive protein on d 7 during lactation than those from sows fed CON. In addition, piglets from sows fed MCS had higher (p < 0.10) immunoglobulin G and M on d 7 during lactation those from sows fed CON. In conclusion, addition of dietary MCS in the lactating sow diet based on corn and soybean meal improved productive performance of sows and their litters and modulated their immune responses.

According to FMVSS No. 109 published by the National Highway Traffic Safety Administration (NHTSA), tire strength and bead unseating tests are included among the major tire safety assessment tests. Uncertainty such as accuracy, precision, and error exist for each test, and these tests shall be verified because there are specified values for passing. To measure this, measurement uncertainty is getting more important with ISO/IEC 17025, which is established for the International Test and Calibration Laboratories since the early 1980s. This paper aims to study in the measurement uncertainty when tire strength and bead unseating test.
