상황인지(Context-Aware) 모바일 클라우드 컴퓨팅은 어플리케이션이 사용자의 위치, 시간, 근처에 사용자와 장치 그리고, 사용자의 상황적인 정보를 분석함으로써, 사용자 경험을 증대시킬 수 있는 새로운 전도 유망한 패러다임이다. 본 논문에서는 Volare 미들웨어를 탑재한 상황인지 모바일 클라우드 컴퓨팅 시스템의 성능 연구를 제공한다. Volare 미들웨어는 리소스와 장치의 상황을 모니터하고, 실행시간에 클라우드 서비스 요구를 동적으로 적용한다. 이러한 접근은 실행시간에 상당한 비용절감 뿐 아니라, 더욱 효과적인 자원과 신뢰할 만한 클라우드 서비스를 제공할 것이다. 또한, 다른 QoS적용 정책에 대한 상황인지 모바일 클라우드 컴퓨팅의 성능을 연구했다. 시뮬레이션 결과는 배터리 레벨이 낮고 CPU 사용량은 높고, 사용자가 초기단계 QoS를 유지할 수 없을 때, 현 적용 정책에 의해서 서비스 비용이 줄어드는 것을 보여준다. 결과적으로, 본 논문에서 제안된 적용정책을 사용하면 상황에 따라 다르게 서비스 비용을 사용자들에게 제공할 수 있다. Context-aware mobile cloud computing is a new promising paradigm that allows to improve user experience by analyzing contextual information such as user location, time of the day, neighboring devices and current activity. In this paper we provide performance study of context-aware mobile cloud computing system with Volare middleware. Volare monitors the resources and context of the device. and dynamically adapts cloud service requests accordingly, at discovery time or at runtime. This approach allows for more resource-efficient and reliable cloud service discovery, as well as significant cost savings at runtime. We also have studied the performance of context-aware mobile cloud computing for different quality of service (QoS) adaptation policies. Our simulations results show that when battery level is low and CPU usage is high and user cannot maintain the initial QoS, service cost is decreased according to current adaptation policy. In conclusion, the current adaptation policy suggested in this paper may improve user experience by providing a dynamically adapted service cost according to a situation.

인종화된 지식 생산과 혐오 정동의 순환 -램지어 논문 비판-

조경희 ( Cho Kyunghee ) 국제한국문학문화학회 2023 사이 Vol.34 No.-

This paper argues that, in view of the body of works J. Mark Ramseyer has published in the past, his recent discussion on the nature of the recruitment of comfort women takes place in the space of hatred and denial of history. In conjunction, it argues that in comparison to the attention his “comfort women papers” received, his controversial views on the lesser known minority groups in Japan, including Zainich Koreans, have not received enough attention. Thus, in making these arguments, the paper reviews the epistemological framework found in Ramseyer’s works, going as far back as three decades, and finds a consistent pattern of cultural racism. The paper then examines the post-war history of ethnic movements and the contemporary landscape of discursive politics in Japan as they relate to postcolonialism discourse, of which the comfort women controversy is a part. In this regard, this paper argues that Ramseyer’s text speaks to the right-wing extremist audience in Japan, while the right wing speaks to transnational audience through him. Thus, the paper argues that his text acquires performativity through participation in national and transnational discourse politics. Lastly, the paper closes with a mention of the spread Japanese historical revisionism, the anti-Korea hate discourse and Ramseyer’s racialized knowledge as they are ominous signs of affective connections in the post-truth era.

마크 램지어의 역사부정과 소수자 혐오 - 관동대지진 조선인 학살, 재일조선인, 부라쿠민 서술 비판 -

조경희 ( Cho Kyunghee ) 한국여성사학회 2021 여성과 역사 Vol.- No.34

하버드대 로스쿨 교수 존 마크 램지어가 일본군 ‘위안부’의 성노예 피해를 부정하는 논문을 발표해 한국, 미국, 일본을 비롯한 국제사회의 비판과 반발을 불러일으켰다. 그런데 램지어는 최근까지 ‘위안부’ 부정과 함께 관동대지진 조선인 학살, 제주 4.3과 재일조선인, 일본 내 소수집단에 대한 차별적 시각을 드러낸 논문을 발표해왔다. 그의 논문에서 공통적으로 볼 수 있는 특징은 재일조선인과 소수집단을 범죄자로 폄하하고 차별과 폭력, 학살이 마치 그들의 책임이자 일본의 정당방위인 것처럼 왜곡한다는 점이다. 또한 그는 기존의 학문적 축적을 무시하고 일본정부의 문서와 학술적 가치가 없는 자료를 자의적으로 활용하는 등 학문윤리에 반하는 글쓰기를 반복하고 있다. 이 글은 램지어의 논문 검토를 통해 아시아의 소수집단에 대한 그의 뒤틀린 인식을 드러냄으로써 역사 부정과 소수자 혐오가 서로 연결되는 지점을 밝히고자 한다. Harvard Law School professor John Mark Ramseyer published a paper denying the victims of sexual slavery by the Japanese military "comfort women", arousing criticism and opposition from the international academic community, including South Korea, Japan, and United States. At the same time Ramseyer has published articles distorting the massacre of Koreans after the Great Kanto Earthquake in 1923 and the identity of ethnic minorities in Japan. A characteristic of his perspective is that he not only disparages Zainichi Koreans and minority groups as criminals, but also distorts them as if discrimination and massacre were their responsibility and Japan's self-defense. In addition, he is violating academic ethics by ignoring existing research and arbitrarily using materials with no academic value. This paper aims to reveal the point where historical denial and hate speech link each other, by examining his description on ethnic minorities in Japan.

The aim of this study was to examine the change in women’s perception on picture books before and motherhood. The subjects were ten women who have children, and their interviews were analyzed. Each subject had a preliminary interview and had in-depth interview once or twice. These interviews were recorded via field notes and audio recorders. The recordings were transcribed and categorized through open coding. The study results showed that they did not have much experience with picture books, and had considered those books to be only for children before they became mothers. After they became pregnant, however, they started to read the picture books and recognized the importance of them. It was also found that the mothers felt some pressure to read the book to their children. At the same time, however, they experienced parenting satisfaction and stress reduction when they read the books communicating to their children.

관동대지진 전후 제국일본의 조선인 대책과 사회사업 사상 - `내선융화` 사업을 중심으로 -

조경희 ( Cho Kyunghee ) 대구사학회 2017 대구사학 Vol.128 No.-

This article examines the ideology of social work of Japanese Empire and the security measure against Koreans before and after the Kanto Earthquake in 1923. The basic policy of Governor-General of Korea after the 3.1 independence movement in 1919 was to divide the pro-Japanese and anti-Japanese, that is, protect the `good citizen` and oppress the `mob`. The social work was actively conceived as a method to approach to the people. The Japanese police announced policy of protecting Koreans in Japan immediately after the Kanto earthquake. The contents were to hold Koreans in camps, to prohibit returning to homeland, and to mobilize them to social work for harmonious integration of Koreans and Japanese(Naisen-yuwa). Koreans were housed in camps under the name of protection and relief and mobilized for labor and restoration projects in the process of fear of massacres. Tokyo branch of Governor-General of Korea and other police officials like Akaiike and Maruyama served as central roles in the security measure against Koreans after the earthquake. They actively assessed the activities of vigilantes who led the massacre of the Korean people after the earthquake, by regarding them as the People`s Police or the “autonomous spirit of citizen”. In addition, they actively supported the Souaikai, labor organization of Koreans in Japan and instructed Koreans to serve the restoration activities after the earthquake. As a result, the Souaikai maintained a firm relationship with the governor-genera of Korea, by developing a post-earthquake reconstruction project. The social work as the method of security measure was soon become the responsibility of the Korean people themselves. In other words, the social work after the Kanto Earthquake brought about a restructuraling that the Koreans partly took charge of the divisional rule. The characteristics of the ideology of social work of Empire can be pointed out the combination of social solidarity theory and `Naisen-yuwa`. The social solidarity theory which conceal the contradictions and conflicts surrounding imperial society, not only served as conter-ideology against socialism, but also translated into meaning of harmony integration of Koreans and Japanese. The ideology of social work which advocated `de-political` and `non-national` had a political effect of reorganizing the imperial order. (Sungkonghoe University / cake734@gmail.com)

에코테크 개념을 적용한 단독주택의 공간디자인 전략에 관한 연구

조경희 ( Kyunghee Cho ),이정교 ( Junggyo Lee ) 한국공간디자인학회 2015 한국공간디자인학회논문집 Vol.10 No.3

(Background and Purpose) Over the years, the energy and environmental problems humans face have become supreme issues. Sustainable development is therefore one of the most important things in the world. As concerns about conservation and saving energy grow, energy efficiency has become a challenge in the spatial design of the built environment. In this study, the Ecology + Technology (Eco-Tech) concept was suggested for spatial design. The main idea of Eco-Tech is that technology is used as a tool to improve energy efficiency and circulation in order to achieve the goal of sustainable architecture. The concept of Eco-Tech was delineated, and a new analysis model in which Eco-Tech was applied to the spatial design of a detached house was proposed. (Method)Previous works show that the term Eco-Tech is not defined as one concept. First, it was necessary to define Eco-Tech, and then Eco-Tech techniques and elements of energy efficiency were chosen. We defined 13 Eco-Tech factors of strategy (ETFs) that are based on principles adopted for Eco-Tech. In addition, Eco-Tech strategies adopted for energy efficiency in a detached house were defined as spatial design items, and ETFs that could be applied in a detached house were identified. Finally, we proposed an analysis model called Essential of Strategy of the Spatial Design in a Detached House for Eco-Tech Application (ESSD-ETA), which provides a standard for applying Eco-Tech factors to spatial design in a detached house. We presented the results of SD-ETF analysis of five real cases, including domestic and foreign cases. (Results)In this study, four main points were determined by analyzing five real cases. First, ESSD-ETA was overbearingly considered for energy-saving techniques using elements of the natural environment and then energy acquisition and energy conservation techniques with technology systems. Second, the principle of controlling the heat environment was applied intensively. Third, an integrated spatial design that applied ETFs was required for each design step in a detached house. Finally, a combined system for applying design elements needed to be considered during the building life cycle in order to aggressively pursue energy efficiency. (Conclusions)This study proposes adopting an Eco-Tech analysis model for spatial design in detached houses as a sustainable design strategy for the future. In addition, it identifies a need for expanded study of Eco-Tech spatial design for a complex of detached house.

1920년대 식민지조선 사회사업의 성격과 그 한계

조경희(Cho, Kyunghee) 호서사학회 2016 역사와 담론 Vol.0 No.80

이 글은 1920년대 제국일본과 식민지조선의 사회사업 행정의 연동과정과 함께 조선총독부 사회사업의 식민지적 특성을 검토하였다. 1차대전후 쌀소동과 조선의 자연재해로 인한 빈곤문제의 심화, 그리고 독립운동의 고조는 이에 대한 대응책으로서 사회사업의 확장을 필요로 하였다. 1920년부터 각도 지방예산에는 사회구제비가 계상되었고, 1921년 조선총독부 내무국에서는 사회과가 설치됨으로써 사회사업은 처음으로 일정한 체계를 갖추었다. 도시부를 중심으로 직업상담소, 인사상담소, 공설주택, 노동숙박소 등의 ‘방빈사업’이 시작되었다. 다만 조선에서는 기초적인 구빈 시스템이 없었을 뿐더러, 압도적인 빈곤수준과 독립운동의 가능성이라는 식민지적 현실을 앞에 두고 사회사업의 내용과 방향성은 노동사업과 교화사업으로 특화되어갔다. 총독부 사회사업 담당자들은 “조선에서의 빈곤선은 내지의 빈곤선과 매우 다르다”고 하면서 조선의 사회상태가 여전히 방빈의 영역에 달하지 못하는 현실을 인식하고 향약과 인보상조의 전통 등을 활용하여 사회사업의 활로를 찾고자 하였다. 한편 1920년대 후반 조선에서 실업자가 증가하면서 인사상담소 일환으로 운영된 직업소개소는 독립적인 공설시설로 전환되어 주요도시에서 노동력 수급조정기관으로서의 역할을 담당하게 되었다. 조선에서 사회사업은 전체 조선인들을 대상으로 광범위한 산업개발과 노동사업, 생활개선을 동시에 추진하는 점에서 구빈 · 방빈 · 교화가 뒤섞인 식민지적 특성을 가졌다. This paper examines characteristics of the social work of Government-General of Korea linkage with administration of Imperial Japan in the 1920s. The expansion of social work in Korean society was due to heightening of the independence movement, as well as deepening of poverty caused by rice riot and natural disasters. Social work of colonial Korea established for the first time in a regular system while the society department were made in the Bureau of Internal Affairs of the Governor-General and the local budget began to include the social relief cost. But new attempt of ‘poverty prevention’ work such as employment counseling and public housing being tried in a part of urban areas did not work decent in Korea. Because there is no underlying poor-relief system and is rather colonial reality of overwhelming poverty and the possibility of independence movement, social work specialized in labor and edification as a result. The Colonial Government often expressed the dilemma that Korea"s present level was not yet in the range of poverty prevention. Meanwhile with the rise of the unemployed in the late 1920s, employment agency became an independent public facilities responsible for labor supply-demand.

패브리병(Fabry) 진단을 위한 혈장 중 Globotriaosylceramide (Gb3)의 탠덤매스 분석법 개발과 임상 응용

윤혜란(Hye-Ran Yoon),조경희(Kyunghee Cho),유한욱(Han-Wook Yoo),최진호(Jin-Ho Choi),이동환(Dong Hwan Lee),Kate Zhang, Joan Keutzer 대한의학유전학회 2007 대한의학유전학회지 Vol.4 No.1

목적: 패브리병은 X-linked 지질 축적 질환으로 α-galactosidase A (α-Gal A)의 결손으로 인해 스핑고당지질인 Gb3의 세포내 축적을 일으키는 병이다. 혈장 중 Gb3 측정은 패브리병 환자의 효소대체요법 후의 모니터링이나 진단에 임상적 의의가 크므로 ESI-MS/MS를 이용한 시료 전처리를 위한 노동력이 덜 들면서 간단, 신속, 고감도로 정량할 수 있는 혈장 중 Gb3분석법을 개발하고자 하였다. 방법 : 혈장을 디옥산으로 50배 희석하여 vortex-mix 및 원심분리를 거쳐 Gb3의 추출 및 분리를 수행한다. 이 때 내부표준액인 C17:0 Gb3를 혈장에 처음부터 첨가한다. 희석과 원심분리된 혈장은 가드컬럼을 통하여 ESI-MS/MS의 다중성분 모니터링 모드에서 분석하여 내부표준액에 대한 8종 Gb3 isoform의 피크면적비를 이용하여 정량한다. 결과 : 혈장의 바탕성분 하에서 8종의 Gb3 isoform이 완전히 잘 분리됨을 확인할 수 있었다. 혈장 중의 8종의 Gb3 isoform 중 50% 이상 차지하는 종류는 C16:0 Gb3 임이 확인되었다. Gb3 isoform이 직선성을 이루는 농도 범위는 0.001-1.0 ㎍/mL이었다. 검출한계(S/N=3)는 C16:0 Gb3의 경우 0.001 ㎍/mL 이었고 정량한계는 0.01 ㎍/mL 이었으며 회수율의 일내재현성(정확도 87-108%와 정밀도 7% 이하)과 일간재현성(정확도 87-110%와 정밀도 13% 이하)은 매우 양호하였다. 결론 : 본 연구에서 개발된 Gb3 분석법은 신속, 정확, 간편하게 패브리병의 1차 스크리닝이나 효소대체요법 전후의 모니터링 및 진단에 유용하게 적용될 수 있을것이다. Purpose : A simple, rapid, and highly sensitive analytical method for Gb3 in plasma was developed without labor-extensive pre-treatment by electrospray ionization M S/M S (ESI-M S/M S). Measurement of globotriaosylceramide (Gb3, ceramide trihexoside) in plasma has clinical importance for monitoring after enzyme replacement therapy in Fabry disease patients. The disease is an X-linked lipid storage disorder that results from a deficiency of the enzyme α-galactosidase A (α-Gal A). The lack of α-Gal A causes an intracellular accumulation of glycosphingolipids, mainly Gb3. Methods : Only simple 50-fold dilution of plasma is necessary for the extraction and isolation of Gb3 in plasma. Gb3 in diluted plasma was dissolved in dioxane containing C17:0 Gb3 as an internal standard. After centrifugation it was directly injected and analyzed through guard column by in combination with multiple reaction monitoring mode of ESI-M S/M S. Results : Eight isoforms of Gb3 were completely resolved from plasma matrix. C16:0 Gb3 occupied 50 % of total Gb3 as a major component in plasma. Linear relationship for Gb3 isoforms was found in the range of 0.001-1.0 ㎍/mL. The limit of detection (S/N=3) was 0.001 ㎍/mL and limit of quantification was 0.01 ㎍/mL for C16:0 Gb3 with acceptable precision and accuracy. Correlation coefficient of calibration curves for 8 Gb3 isoforms ranged from 0.9678 to 0.9982. Conclusion : This quantitative method developed could be useful for rapid and sensitive 1st line Fabry disease screening, monitoring and/or diagnostic tool for Fabry disease.
