본 연구에서는 소수성 구현을 위한 표면 거칠기가 접촉각과 접촉각 이력에 미치는 영향을 평가하였다. 초발수 특성을 극대화하기 위해, 액적이 이동하기 위해 필요한 구름저항력을 제안하였으며, 이에 대한 평가를 통하여 표면에 형성한 패턴이 접촉각 이력 및 구름저항력에 큰 영향을 주는 것을 확인하였다. 초발수 특성이 요구되는 실제 응용을 위해서는 액적의 이동에 필요한 에너지를 최소화하기 위하여 접촉각을 극대화하고 동시에 접촉각 이력을 최소화하기 위한 표면 패턴 형상의 최적화가 요구됨을 확인하였다. In this study, the effects of the contact angle (CA) and contact angle hyteresis (CAH) of planar and nano-patterned surfaces on rolling resistance of water droplet were studied. Based on the investigation on the CAH of water droplet on surfaces with various static wettability, it was found that the rolling resistance coefficient of water droplet is highly influenced by the surface pattern as well as CAH. The observed results suggest that the optimal surface patterns should be designed in order to minimize the rolling resistance of water droplet for the practical applications where superhydrophocitiy is required.

리타겟팅 광고의 지각된 인지적 속성이 광고태도, 클릭의도, 회피의도에 미치는 영향

조원경(Cho, Won-Kyoung),조창환(Cho, Chang-Hoan) 한국광고홍보학회 2024 광고연구 Vol.- No.140

코로나19 팬데믹을 기점으로 온라인 쇼핑 시장이 폭발적으로 성장하였고 이에 따라 온라인 쇼핑 이력 데이터를 기반으로 하는 ‘리타겟팅 광고’의 중요성 또한 높아졌다. 본 연구는 소비자들이 인식하는 리타겟팅 광고의 지각된 인지적 속성이 광고 효과에 미치는 영향을 살펴보고자 하였다. 탐색적 요인 분석 결과 긍정 요인인 ‘지각된 유용성’, ‘지각된 관련성’, ‘쇼핑 선택지 압축’, ‘쇼핑 리마인더’와 부정 요인인 ‘지각된 피감시’, ‘프라이버시 염려’, ‘끈질김 및 잔류성’, ‘지각된 침입성’이 추출되었다. 또한, 본 연구는 리타겟팅 광고의 지각된 인지적 속성 요인이 리타겟팅 광고 태도, 클릭 의도, 회피 의도에 미치는 영향을 규명하고자 하였다. 그 결과 첫 번째, 광고 태도에 영향을 미친 요인으로는 ‘지각된 유용성’, ‘쇼핑 선택지 압축’, ‘지각된 침입성’이 확인되었고 두 번째, 클릭 의도에 영향을 미친 요인은 ‘쇼핑 선택지 압축’과 ‘지각된 침입성’이 있었다. 끝으로, 회피 의도에는 ‘끈질김 및 잔류성’과 ‘지각된 침입성’이 영향을 나타내는 것을 확인할 수 있었다. 본 연구는 리타겟팅 광고에 대한 소비자 측면의 지각된 인지적 속성 요인을 살펴봄으로써 향후 리타겟팅 광고 전략을 위한 실질적인 인식 요인을 도출하였다는 것에 실무적 시사점이 있다. Starting with COVID-19 pandemic, the online shopping market has exploded, and accordingly, the importance of ‘Retargeting Advertising’ based on online shopping history data has also increased. This study attempted to examine the effect of the perceived cognitive attributes of retargeting advertising on the advertising effect. As a result of exploratory factor analysis, positive factors such as ‘Perceived Usefulness’, ‘Perceived Relevance’, ‘Shopping Option Compression’, ‘Shopping Reminder’, and negative factors such as ‘Perceived Monitoring’, ‘Privacy Concern’, ‘Persistence and Residuality’, and ‘Perceived Intrusion’ were extracted. In addition, this study attempted to investigate the effect of the perceived cognitive attribute factors of retargeting advertising on Ad attitude, click intention, and avoidance intention. As a result, factors that influenced Ad attitudes included Perceived Usefulness’, ‘Shopping Option Compression’ and ‘Perceived Intrusion’ and factors that influenced click intention were ‘Shopping Option Compression’ and ‘Perceived Intrusion’. Finally, it was confirmed that ‘Persistence and Residuality’ and ‘Perceived Intrusion’ had an effect on avoidance intention. This study has practical implications for providing a practically useful retargeting advertising recognition factor in establishing a strategy for retargeting advertising in the future by examining perceived cognitive attribute factors on the consumer side of retargeting advertising.

비운의 애국애족 운동가 동오(東吾) 안승구(安承龜) 선생

조원경(Cho, Won-kyoung) 영남퇴계학연구원 2021 퇴계학논집 Vol.- No.28

동오 안승구선생은 혁신 유림으로 평생을 헌신하셨을 뿐 아니라 나라의 국운이 위기에 빠져 있을 때 유교의 애국적 의리의 희생정신으로 자신의 한 몸을 희생하였다. 그러나 나라얼연구소가 2020년 학술토론을 하기 전에는 그 분의 행적이 알려지지 않았을 뿐만 아니라 오히려 학문적으로 일천한 학자들에 의해 때로는 오해와 왜곡된 평가를 받았다. 본 글은 동오 안승구에 관한 미발견 자료들을 수합하여 그의 일생을 차례로 정리하였다. 1. 그는 유교정신의 교육을 부모로부터 받은 유학자이며 2. 고향인 황해도 연백에서 국채보상운동기금을 마련하였으며 3. 서간도 독립기지를 마련하기 위해 몇 번의 義盜를 행하여 사형선교를 받고 3년을 서대문형무소에서 수감생활을 한 독립운동가였다. 4. 출옥후 애국사상에 바탕을 둔 충남홍성의 <유교부식회> 주최 전조선 유림대회 부의장을 맡아 유교의 새로운 길을 제시하는 삶을 살다가 40대 전반의 짧은 나이로 세상을 떠난 의인이었다. 이번 학술적 논의를 바탕으로 동오 안승구선생의 애국사상과 꺼져가는 유교정신의 부광復光을 꿈꾼 자임을 널리 알리는 계기가 되어야 한다. Dongo Ahn Seung-Gu devoted his life to studying innovative Confucianism and sacrificed his body by practicing Confucian patriotic loyalty when the country faced a crisis. However, his achievements remained unknown until the Naraeol Institute held the 2020 academic seminar. On the contrary, Ahn was sometimes misunderstood and distorted by scholars with a lack of knowledge. This paper gathered undiscovered data related to Dongo Ahn Seung-Gu and summarized his lifetime. 1. Ahn Seung-Gu was a Confucian scholar educated by his parents. 2. He raised a national debt redemption movement fund in his hometown called Yeonbaek, Hwanghae-do. 3. As an independence activist, he performed several thefts out of good will to build the independence base in Seogando, was sentenced to death, and spent three years at the Seodaemun Prison. 4. After getting released from prison, he became the vice-chair of the Joseon Confucian Literati Rally hosted by the Confucian Association in Hongseong, Chungcheongnam-do, based on patriotism. Ahn deceased at a young age of early 40s after presenting new paths to be headed by Confucianism. The academic seminar this time should be an opportunity to widespread Dongo Ahn Seung-Gu as a Confucian scholar who practiced patriotism and dreamed of the revival of Confucianism.

경남지역 여성 평신도 신사참배 거부 공동체

정중호(Chong Joong-Ho),조원경(Cho Won-Kyoung) 한신대학교 신학사상연구소 2007 신학사상 Vol.0 No.138

  본 논문의 목적은 경남지역에서 일어난 기독교 평신도 중심, 특히 여성 중심의 신사참배 거부 공동체를 연구하여 그 역사적 실상을 파악하는 데 있다. 경남 남해군 내산의 성산 공동체, 하동군 북방리의 공동체, 산청군 중산리 지리산 공동체 등지의 연구에서 찾아볼 수 있는 것은, 첫째로 세 공동체 모두가 신사참배 거부 공동체였으며 기독교 평신도 중심이었다는 사실이다. 그리고 남해군 내산의 성산 공동체와 북방리 공동체의 경우 기독교 평신도 여성들의 활동이 두드러진 공동체였다는 사실이 주목할 만하다. 둘째로 이들은 지역상 은거하기에 적절한 지리산과 남해의 섬을 중심으로 하나의 벨트를 형성하고 있다는 사실이다. 셋째로 손양원 목사의 영향이 컸으며 간접적으로는 경남 출신인 주기철 목사의 영향도 있었음을 발견할 수 있다.   From studies of Gyeongnam area communities in Namhae-gun Naesan, Hadong-gun Bukbang-li, and Mt. Jirisan at Sanchung-gun Jungsan-li, we find, firstly, all three communities were made up of anti-Shinto resistance groups and centered upon lay members of the church instead of church officials or leaders. We also note how female members of the church were active in communities in the Seongsan community of Namhae-gun Naesan and Bukbang-li. Kim So Gab-sook of Namhae-gun Naesan, Lee Anna and Chong In-sub of the Mt. Jirisan Community at Sanchung-gun Shichun-myun Jungsan-li were all female leaders as well as lay members of the church. We also find that most church participants were lay members.   Second, these communities formed a geographical chain linking Mt. Jirisan and outlying islands. With Mt. Jirisan at the center, we find the Sanchung-gun Mt. Jirisan Community to the north, Okjong-myun Bukbang-li Community to the south, and the island Namhae-gun Seong-san Community further south. Mt. Jirisan and these islands were particularly excellent hiding locations.   Third, we find these groups were strongly influenced by Rev. Son Yang-won. Son"s wife and children were part of the Naesan Community in Namhae Sam-dong, and the Okjong-myun Bukbang-li Community was led by Hwang Duk-soon, who was taught by Rev. Son. In particular, the Bukbang-li Community was the recipient of letters from Rev. Son during his imprisonment. The community was also indirectly affected by Rev. Ju Gichul, who was a native of the Gyeongnam area. Shin Jong-gyun, a leader of the Mt. Jirisan Community at Sanchung-gun Shichun-myun Jungsan-li, was strongly influenced by Rev. Ju"s faith.   Finally, we note that comprehensive studies of anti-shinto resistance communities have been neglected in scholarship after 1945, greatly due to church schisms and disagreements between denominations. The Namhae Naesan community has been regarded as an important religi

Antineutrophil Cytoplasmic Autoantibody 양성인 결절성 다발동맥염 1 예

김대원,박정식,최정은,유은실,조원경,이미화,제수정,홍진선,정해혁,박흥동 대한내과학회 1993 대한내과학회지 Vol.45 No.5

Anti-neutrophil cytoplasmic autoantibodies are serologic marker for various disease, ranging from multi system vasculitis, such as Wegner's granulomatosis and polyarteritis nodosa, to renal-limited disease (that is, idiopathic crescentic glomerulonephritis) These ANCA-associated diseases share the pathologic feature of necrotizing vascular inflammation with scant immune deposition. In vitro studies suggest that these diseases also have a common immunopathogenesis mediated by ANCA-induced neutrophil activation. We experienced a case of ANCA positive polyarteritis nodosa. The physical exammination of abdomen showed mild direct tenderness on the right upper quadrant. Laboratory studies on admission revealed leukocytosis, elevated ESR, proteinuria, hematuria, and elevated alkaline phosphatase. Liver bipsy and renal biopsy revaled characteristic findings of Polyarteritis Nodosa. Serologic test for ANCA showed central type with 1:1280 of titer. The patients was treated with prednisolone and oral cyclophosphamide but the disease progressed to end-stage renal disease.

ACTH 분비 뇌하수체 선암에 의한 쿠싱병

이문호,이정교,이기업,송영기,박중열,김기수,조원경,최기영 대한내분비학회 1994 Endocrinology and metabolism Vol.9 No.2

Primary carcinoma of the pituitary is only rarely reported. About half of the reported cases are nonfunctional. It is generally agreed that the presence of distant metastasis is required to clearly establish the diagnosis of pituitary carcinoma. We have experienced a case of ACTH-producing pituitary carcinoma causing Cushing's syndrome which could be diagnosed by histologic features only without evidence of distant metastasis. A 35-year-old female with Cushingoid appearance was diagnosed as Cushing's disease after biochemical and neuroradiological evaluation. Near total removal of the pituitary tumor was performed. By histopathologic examination, the tumor revealed evidences of histological malignancy such as prominent nuclear pleomorphism, frequent mitoses and extensive tumor necrosis. Pseudosarcomatous components were also noted. By immunohistochemical studies, the tumor cells expressed ACTH. However, there was no evidence of distant metastasis at the initial operation. She was diagnosed as having ACTH producing pituitary carcinoma by histologic feature only. One month later, she complained progressive nausea and vomiting, and follow-up brain MRI revealed regrowing pituitary mass. She was reoperated and near total tumor bulk was removed again followed by radiotherapy with 5580 rads. Four month after the second operation, she developed generalized tonic clonic seizure. Brain CT showed multiple enhancing nodules on left temporal and frontal lobes, and around falx cerebri. She refused further treatment and was managed only with anticonvalsants. About month after discharge she died at home(J Kor Soc Endocrinol 9:136-140, 1994).
