정윤정 ( Jeong Yun Jeong ),정경운 ( Jeong Kyung Woon ) 아시아문화학술원 2017 인문사회 21 Vol.8 No.2

최근 한국 사회는 대통령과 최측근들이 연루된 권력남용 및 비리사건으로 파문이 일었다. 대통령과 정부에 분노한 많은 시민들이 거리와 광장으로 모여들었고, 언론과 인터넷은 이번 사태와 관련한 이슈들을 신속하게 전달하였다. 특히 소셜 미디어는 누구나 자유롭게 의견을 개진하고 실시간으로 정보를 제공할 수 있는 장으로 역할하면서, 국정농단 사태와 관련한 여러 의미들을 생산해냈다. 본 연구에서는 소셜 미디어의 소통방식과 집단지성 생성과정이 퍼스 기호학의 `세미오시스(Semiosis)`와 유사함을 설명하고자 한다. 소셜 미디어의 소통방식과 집단지성 생성과정을 알아보기 위해 빅데이터 수집 프로그램인 노드엑셀(NodeXL)을 사용하여 트위터(Twitter) 데이터를 수집하고 네트워크를 분석했다. 수집한 자료의 키워드는 이번 국정농단 사건과 관련된 `청문회`와 `탄핵`이다. 분석 결과, 트위터 상에서 하나의 의견(기호)이 다양한 의미들로 확장되고 새로운 기호들이 생성되는 것을 확인할 수 있었다. 또한 다양한 의견을 가진 클러스터(Cluster)들이 네트워크 상에서 상충하는 양상을 볼 수 있었으며, 온라인상의 네트워크가 오프라인과 연계되면서 실제 사회적 움직임을 촉발시키고 있음을 알 수 있었다. A scandal recently plagued Korean society, namely the corruption and influence-peddling scandal involving close confidants of President Park. The scandal pushed many people to take to the streets and squares to demonstrate their anger against the President and Government. Social media specifically had a role in communicating information in real time, allowing the people to express their opinions freely and creating several meanings related to this situation. In this research, we explain that social media as a method of communication and the process of collective intelligence resemble the semiosis referred to in Peirce`s Semiotics. To investigate the social media communication method and collective intelligence generation process, we collected “Twitter” data and analyzed the network using NodeXL. The key words of the collected data were “Hearing” and “Impeachment.” The results of the analysis of the Twitter data confirmed that one opinion(sign) on Twitter extended various meanings and produced new signs. In addition, we observed conflict of the clusters with varied opinions and confirmed that online networks can trigger real social movements when connected offline.

문화적 의미를 통해 본 ‘광주의 빛’ 연구

정윤정(Jeong, Yun Jeong),김진아(Kim, Jin A) 한국전시산업융합연구원 2014 한국과학예술융합학회 Vol.17 No.-

광주의 지명에서 유래된 ‘빛고을’은 1980년대부터 광주를 지칭해온 별칭이다. 이를 계기로 광주시는 광산업을 적극 진흥하기 시작했고, 빛의 모티브를 문화산업으로 확장?적용해 왔다. 특히 ‘빛’은 광주시에서 최근 몇 년간 개최된 문화예술 관련 행사와 공간기획에서 독보적인 키워드로 대두되었다. 그러나 산업과 문화행사를 위한 활용에 비해 그 근간이 되는 빛의 의미에 대한 진지한 논의와 연구는 미비하였으며, 광주는 주로 빛의 물리적인 특징에 연계된 경제적 효과 창출에 집중해 왔음을 알 수 있었다. 본 연구는 이러한 문제의식 아래 광주시가 왜 빛이라는 개념을 이용하여 도시를 브랜딩하고 있으며, 광주의 빛이 과연 무엇이고 어떻게 규정되어야하는지에 대한 비평적 고찰을 수행하고자 했다. 우선 빛의 과학적, 정신적, 문화적 정의와 의미를 짚어보고 광주 지명의 역사적 유래와 광산업, 5?18 운동과 관련된 빛의 개념을 추적하였다. 그리고 현재 광주시에서 진행되고 있는 빛 관련 문화행사 중 ‘광주세계光엑스포’와 ‘미디어아트페스티벌’을 분석하고 문제점을 도출하였다. 이러한 문화행사의 확산 속에서 무엇보다 필요한 것은 빛의 의미에 대한 인문학적, 문화적 숙고라 간주하며, 광주의 빛이 나아가야 할 방향에 대해 다음과 같이 제안한다. 첫째, 광주의 빛은 과학기술과 문화예술이 조화를 이룬 융합의 형태를 지향해야한다. 둘째, 동양의 음양사상과 서양의 해체주의를 바탕으로 과학과 예술, 산업과 문화, 물질과 정신 등의 이분법적인 사고와 위계질서들에 대해 도전해가는 과정이어야 한다. 셋째, 광주의 민주, 인권 정신을 바탕으로 이를 실천하는 열린 개념이어야 할 것이다. 지역의 경제 발전이라는 목표 아래 급격하게 진행되어온 문화산업의 흐름 속에서 그동안 소외되어왔던 광주의 역사와 정신을 담은 빛의 의미 및 그 표현에 대한 진지한 연구와 더불어 광주가 지향해야 할 빛의 방향에 대한 논의가 필요한 시점이다. ‘Light Village’ was named after the place name of Gwangju and has been used as another name that indicated Gwangju after 1980s. Emphasizing the name of ‘Light Village’, the city of Gwangju has been literally and actively supporting the optical electronics industry in the subject of ‘light’ and started expanding the scope of the motif of light into the cultural industry. Especially, the light has been in a limelight as a matchless keyword in the field of cultural and artistic events and spaces for the past few years. However, compared to how Gwangju has been branding the city with the light as a major industry or an event, an in-depth discussion of the meaning of ‘Light of Gwangju’ is currently superficially dealt with. This study started from an inquiry as to what was the origin of ‘Light Village’ in Gwangju with an awareness of an issue along with the meaning of the light in Gwangju and also why the city of Gwangju is currently branding the city by using the light. Hereupon, this study was intended to analyze the cultural events and spaces in progress in Gwangju and to define the identity and the meaning of the light in Gwangju based on aforementioned consideration of the light. First of all, the light of Gwangju not only is in the form of industrial light in the perspective of scientific technology but also pursues to the unified form in harmonization with cultural art. Secondly, the light of Gwangju is based on the open thought derived from the harmonization of yin and yang idea East Asia and also de-constructivism in the Western world including the brightness as well as darkness behind. Third, it is suggested to establish the identity of the light of Gwangju in connection with democracy and human right as a spirit of Gwangju and also regard it as an opened concept not in the fixed concept and form but in the relationship. Therefore, it shall be a continuous course for criticizing and removing the trends that exclude dichotomous thought and an order of rank. In the flow of cultural industry of Gwangju city rapidly accompanied for the rapid local economic development, it is of an assignment to identify how to research and develop the light in the history and spirit of Gwangju.

Standard short-course chemotherapy (SSC) is recommended for new patients with pulmonary tuberculosis (TB). This approach has been regarded as among the most effective tools for preventing the development of resistance to anti-TB drugs. We report on the development of multidrug-resistance during SSC in a patient with drug-susceptible TB. Isoniazid, rifampin, pyrazinamide, and ethambutol were started, and negative culture conversion was obtained. Ethambutol was discontinued after 5 weeks of treatment due to visual dysfunction, and pyrazinamide was discontinued after a 2-month phase of intensive treatment. However, M. tuberculosis was cultivated from sputum collected after 9 weeks of treatment. Drug-susceptibility testing revealed resistance to isoniazid, rifampin, ethambutol, and rifabutin. Given that the patient took medication regularly, this observation suggests the possibility that some patients acquire drug resistance during SCC. (Korean J Med 2012;82:614-617)

Recently, there has been increasing attention about SNS(Social Network Service) and shared mental model as measures of competitiveness for team and their impacts on job performance. This research scrutinizes impacts of SNS on team shared mental and learning performance in university students and this study tries to explain whether degrees of team shared mental mediates the relationship between SNS engagement and learning performance. To achieve the goals, this study developed conceptual measurements of SNS engagement, team shared mental and learning performances based on previous researches. This study proposed hypotheses and conducted surveys with 209 sets of questionnaire from university students. The results are as follows. First, SNS engagement had affected learning performances. It has been proved that SNS engagement has positive impacts on learning performances. Secondly, the test proved that SNS engagement influences team shared mental. Among them, SNS engagement has the strongest influence on the team-work shared mental and also it has the strongest influence on the task-related shared mental indicator. Third, the hypothesis that team shared mental mediates between SNS engagement and learning performance is fully accepted. Results suggested that when university students make efforts to develop their SNS engagement they become more committed to team shared mental and also more likely to develop their learning orientation.

This study was conducted from May to December 2016 to investigate the prevalence of antibody titers for Newcastle disease (ND), Infectious Bronchitis (IB), Egg drop syndrome (EDS), Avian pneumovirus (APV), Fowl Typhoid (FT), Mycoplasma gallisepticum (MG), Mycoplasma synoviae (MS) in laying hens in Incheon area. In ND, 418 (99.5%) of the 420 outbreaks were positive. IB showed 330 (78.5%) positive antibody out of 420 cases. EDS showed 419 (99.7%) positive seropositive rates among 420 cases. In the case of APV, 357 cases (85%) were positive in 420 cases. In the case of PT, the positive rate of antibody was 128 (30.4%) out of 420 cases. Among the 420 cases of MG, 222 cases (52.8%) were positive for antibodies. In the case of MS, 395 out of 420 cases (94.0%) were positive. This result suggests that the positive rate of antibody for PT in Incheon area was low. And it was also clear that MS without vaccine is now rampant in Incheon.

강화 석모도 지역 온천수와 지하수의 수리지구화학 및 동위원소 연구

김규한,정윤정,정찬호,장미경개,Kim, Kyu-Han,Jeong, Yun-Jeong,Jeong, Chan-Ho,Keisuke, Nagao 대한자원환경지질학회 2008 자원환경지질 Vol.41 No.1

강화 석모도 지역 석모도 온천수의 영족기체와 온천수의 지화학적 진화와 기원을 해석하고 온천수의 지화학적 특성을 규명하기 위해 온천수, 지하수, 지표수의 수리화학, 안정 동위원소, 영족기체 동위원소 분석이 이루어졌다. 온천수와 지하수의 pH는 각각 $6.42{\sim}6.77,\;6.01{\sim}7.71$로 약산성을 보이고 있다. 석모도 온천 지역의 온천수의 유출수온은 $43.3{\sim}68.6^{\circ}C$이다. 온천수의 전기전도도는 $60,200{\sim}84,300{\mu}S/cm$으로 비교적 높은 값이며 석모도 온천수가 해수와 혼합되어졌음을 암시하고 있다. 석모도 온천수의 화학 조성은 Na-Ca-Cl형이다. 반면, 지하수와 지표수는 각각 Na(Ca)-$HCO_3$, Na(Ca)-$SO_4$형과 Ca-$HCO_3$ 형으로 구분된다. 석모도 온천수의 산소와 수소 동위원소비는 각각 $-4.41{\sim}-4.47%o$와 $-32.0{\sim}-33.5%o$로 순환수 기원이다. 지하수에서의 산수 수소 동위원소비는 각각 $-7.07{\sim}-8.55%o,\;-50.24{\sim}-59.6%o$이다. 석모도 온천수에 $^{18}O$와 $^2H$가 부화된 특성은 온천수가 담수와 해수의 혼합대에서 유래되었음을 암시하고 있다. 석모도 온천수 중의 황산염이온의 황 동위원소비는 $23.1{\sim}23.5%o$로 이 지역 해수의 황 동위원소비(20.2%o)와 유사하다. 이는 온천수의 황이 해수의 황산염으로부터 유래되었음을 의미한다. 석모도 온천수의 $^3He/^4He$ 비는 $1.243{\times}10^{-6}{\sim}1.299{\times}10^{-6}cm^3STP/g$로 온천수 중의 He 가스가 부분적으로 맨틀에서 유래되었음을 보여준다. 온천수에서의 아르곤 동위원소비$(^{40}Ar/^{36}Ar=298{\times}10^{-6})cm^3STP/g$는 대기기원의 값을 보인다. The hydrochemical and isotopic (stable isotopes and noble gas isotopes) analyses for hot spring waters, cold groundwaters and surface water samples from the Seokmodo hot spring area of the Ganghwa province were carried out to characterize the hydrogeochemical characteristics of thermal waters and to interpret the source of thermal water and noble gases and the geochemical evolution of hot spring waters in the Seokmodo geothermal system. The hot spring waters and groundwaters show a weakly acidic condition with the pH values ranging from 6.42 to 6.77 and 6.01 to 7.71 respectively. The outflow temperature of the Seokmodo hot spring waters ranges from $43.3^{\circ}C\;to\;68.6^{\circ}C$. Relatively high values of the electrical conductivities which fall between 60,200 and $84,300{\mu}S/cm$ indicate that the hot spring waters were mixed with seawater in the subsurface geothermal system. The chemical compositions of the Seokmodo hot spring waters are characterized by Na-Ca-Cl water type. On the other hand, cold groundwaters and surface waters can be grouped into three types such as the Na(Ca)-$HCO_3$, Na(Ca)-$SO_4$ and Ca-$HCO_3$ types. The ${\delta}^{18}O\;and\;{\delta}D$ values of hot spring waters vary from -4.41 to -4.47%o and -32.0 to -33.5%o, respectively. Cold groundwaters range from -7.07 to -8.55%o in ${\delta}^{18}O$ and from -50.24 to -59.6%o in ${\delta}D$. The oxygen and hydrogen isotopic data indicate that the hot spring waters were originated from the local meteoric water source. The enrichments of heavy isotopes ($^{18}O\;and\;^2H$) in the Seokmodo hot spring waters imply that the thermal water was derived from the diffusion Bone between fresh and salt waters. The ${\delta}^{34}S$ values ranging from 23.1 to 23.5%o of dissolved sulfate are very close to the value of sea water sulfate of ${\delta}^{34}$S=20.2%o in this area, indicating the origin of sulfate in hot springs from sea water. The $^3H/^4He$ ratio of hot spring waters varies from $1.243{\times}10^{-6}\;to\;1.299{\times}10^{-6}cm^3STP/g$, which suggests that He gas in hot spring waters was partly originated from a mantle source. Argon isotopic ratio $(^{40}Ar/^{36}Ar=298{\times}10^{-6}cm^3STP/g)$ in hot spring waters corresponds to the atmospheric value.

전립선암 영상유도 방사선 치료시 골반내장기의 체적변화에 따른 표적장기의 변화

동갑상,백창욱,정윤정,배재범,최영은,성기훈,Dong, Kap Sang,Back, Chang Wook,Jeong, Yun Jeong,Bae, Jae Beom,Choi, Young Eun,Sung, Ki Hoon 대한방사선치료학회 2016 대한방사선치료학회지 Vol.28 No.2

목 적 : 전립선암 방사선치료에서 방광과 직장의 체적변화에 따른 전립선의 위치 및 모양변화를 파악하여 이들 변화가 표적체적에 미치는 영향을 파악하고자 하였다. 대상 및 방법 : 본원 전립선암 protocol에 따라 방사선치료를 시행한 환자 6명을 대상으로 후향적 영상자료분석 및 윤곽설정을 시행하였다. 설계용 computed tomography (pCT)와 분할치료 시 획득된 cone-beam CT (CBCT)를 이용하여 전립선, 방광, 그리고 직장의 윤곽을 설정(contouring)하였다. 두 영상자료의 골격구조 기반 조사영역맞춤을 통해 전립선의 위치변화를 관찰하였으며, 전립선의 위치변화, 모양변형, 그리고 크기변화를 종합적으로 분석하기 위해 Dice similarity coefficient(DSC)를 이용하였다. 결 과 : 전립선의 체적은 pCT에서 평균 37.2cm3 로 측정되었으며 약 5% 이내의 크기변화를 나타내었고, 전립선의 DSC는 평균 89.9%로 환자마다 다양한 분포양상이 관측되었다. 방광의 체적변화에 따른 전립선의 DSC 변화를 상관분석한 결과 관련성을 찾을 수 없었지만(r=-0.084,p=0.268), 방광체적의 증감에 따른 층화분석 시 방광의 체적이 증가한 경우에서 DSC 와 방광변화량 간에 통계적으로 유의한 음의 상관관계를 관찰할 수 있었다(r=-0.230,p=0.049). 직장의 체적변화에 따른 전립선의 DSC 변화를 분석한 결과 직장의 체적변화가 증가함에 따라 DSC가 감소하는 것으로 나타났다(r=-0.162,p=0.032). 직장체적에 대한 층화분석에서는 체적이 pCT보다 증가한 경우에 강한 상관관계를 나타내었다 (r=-0.240,p=0.020). 결 론 : 방광과 직장의 체적을 일정하게 유지하는 것이 치료의 정확도를 보장하는 것은 아닌 것으로 나타났다. 따라서 전립선암의 방사선치료 시 CBCT를 이용한 연조직 기반의 조사영역맞춤이 중요하며, 직장풍선(rectal balloon) 등을 이용한 체적관리가 치료정확도를 유지하는데 역할을 할 것으로 사료된다. Purpose : To quantify the inter-fractional variation in prostate displacement and their dosimetric effects for prostate cancer treatment. Materials and Methods : A total of 176 daily cone-beam CT (CBCT) sets acquired for 6 prostate cancer patients treated with volumetric-modulated arc therapy (VMAT) were retrospectively reviewed. For each patient, the planning CT (pCT) was registered to each daily CBCT by aligning the bony anatomy. The prostate, rectum, and bladder were delineated on daily CBCT, and the contours of these organs in the pCT were copied to the daily CBCT. The concordance of prostate displacement, deformation, and size variation between pCT and daily CBCT was evaluated using the Dice similarity coefficient (DSC). Results : The mean volume of prostate was 37.2 cm3 in the initial pCT, and the variation was around ${\pm}5%$ during the entire course of treatment for all patients. The mean DSC was 89.9%, ranging from 70% to 100% for prostate displacement. Although the volume change of bladder and rectum per treatment fraction did not show any correlation with the value of DSC (r=-0.084, p=0.268 and r=-0.162, p=0.032, respectively), a decrease in the DSC value was observed with increasing volume change of the bladder and rectum (r=-0.230,p=0.049 and r=-0.240,p=0.020, respectively). Conclusion : Consistency of the volume of the bladder and rectum cannot guarantee the accuracy of the treatment. Our results suggest that patient setup with the registration between the pCT and daily CBCT should be considered aligning soft tissue.
