        황순원 소설의 상징에 나타난 생태학적 관점

        최선영(Choi, Sun-young) 문학과환경학회 2015 문학과 환경 Vol.14 No.3

        Novel named “Trees standing on the slope” was written by novelist Hwang Sun-won after the 1960s that belonged to latter half period of Hwang"s novel works. Before the 1960s, Hwang"s novel works described fragments of human world that expressed not only conciliation but also warm humanity, while after the 1960s, his works reflected realities of the society to investigate the society deeply. However, evaluation and rhetoric of his works came from his works at initial times. However, the novel works made change at quality level to a certain degree considering geopolitical factors more than Hwang Sun-won"s works in previous times did. Novel of “Trees standing on the slope” that belonged to novel of latter half period of Hwang Sun-won had different characters and symbols than those of other novels of Hwang had. This study criticized analysis upon characters focused on humanism to find out values from various kinds of points and to interpret Hwang"s point of view of the world at “Trees standing on the slope”. Sukee"s path could be interpreted to be motherhood of reconciliation and embracement from point of view of humanism that Hwang Sun-won adhered to. Such a thought could be criticism in the 1950s that was abstract and absolute humanism. And, mythified violence of motherhood was thought to be reinforced. In this study, ‘pruning’ of Chapter II interpreted value of dualism to investigate Sukee and her pregnancy from point of view of not common value but multiple values. Men could get new fruit after pruning of trees or could not. Suggestion of possibility of fruit was not thought to give optimistic prospect. On the contrary, focus on pruning was likely to finish end. Of course, the novelist gave an alternative for not only destruction but also construction in his novel work that could not be practical way of before and after realities. Value of individuals could not be judged from point of view of humanism behavior to overcome cruelty of war experience and to recover humanism. The ideology of humanism for affirmative and optimistic future of pains of post-war generation in the history was rather abstract and ideological. Hwang Sun-won deeply investigated by symbols and characters. For instance, an woman named Sukee was thought to be new character who overcame the limitation to be made by the novelist. The study investigated the work carefully to have viewpoint of current times. Study on Hwang Sun-won"s novel was not rescue of completed world but cognition on new realities with possibility of incompleteness to create characters and to interpret in various ways.

        말기암환자에서 혈중 비타민 D 농도와 생존기간과의 관련성

        최선영,최윤선,황인철,이준영,Choi, Sun Young,Choi, Youn Seon,Hwang, In Cheol,Lee, June Young 한국호스피스완화의료학회 2015 한국호스피스.완화의료학회지 Vol.18 No.2

        목적: 국내 말기암환자를 대상으로 혈중 vitamin D 농도를 측정하고, 생존기간과의 관련성에 대하여 확인해 본다. 방법: 2012년 5월부터 15개월 동안, 국내 일개 병원의 말기암환자 96명을 대상으로 후향적 의무기록 조사를 시행하였다. Vitamin D 결핍에 영향을 미치는 요인들을 파악하기 위해 단순 로지스틱 회귀분석과 다중 로지스틱 회귀분석을 실시하였고, vitamin D가 생존기간에 미치는 영향을 파악하기 위해 다변수 분석으로 Cox's proportional hazard regression analysis를 실시하였다. 결과: 대상자의 평균 연령은 $67.06{\pm}13.77$세였고, 모든 대상자가 ECOG PS 3점 이상이었으며 혈중25(OH)D 농도는 평균 $8.60{\pm}7.16ng/ml$였다. 3명(3.1%)만이 vitamin D 충분상태(혈중 25(OH)D 농도${\geq}30ng/ml$)였으며, 5명은 vitamin D 상대적결핍상태(혈중 25(OH) 농도 20~30 ng/ml)였고, 13명(13.5%)은 vitamin D 결핍(혈중 25(OH)D 농도 10~20 ng/ml), 75명(78.1%)은 vitamin D 중증결핍상태(혈중 25(OH)D<10 ng/ml) 였다. 혈중 빌리루빈 농도가 1.2 mg/dl 이상인 경우 vitamin D 중증결핍과 관련이 있었다(Odds ratio, OR=5.041; P=0.039). 혈중 빌리루빈 농도가 높을수록 혈중 vitamin D 농도가 낮았으며, 고빌리루빈혈증인 환자는 vitamin D 중증결핍에 속할 위험이 더 크고(OR=18.476, P<0.05), 중앙생존기간도 유의하게 짧았다. Vitamin D 중증결핍인 경우 추정된 중앙생존기간은 짧았으나 통계적 유의성은 없었다. 다변량 분석결과에서 vitamin D 중증결핍은 사망의 위험인자가 아니었다. 결론: 말기암환자에서 혈중 vitamin D 결핍은 매우 심각하였으나, vitamin D 중증결핍이 생존기간에 영향을 미치지는 않았다. Purpose: We aimed to investigate how serum vitamin D levels are related to survival of terminally ill cancer patients. Methods: From May 2012 through June 2013, a retrospective chart review was performed on 96 hospice patients. Univariate and multivariate logistic regression analyses were conducted to identify factors associated with severe vitamin D deficiency and Coxcy and Coxional hazard analyses were used to evaluate effects on survival. Results: The mean vitamin D level in patients was $8.60{\pm}7.16ng/ml$. Vitamin D was severely deficient (<10 ng/ml) in 75 patients (78.2%), deficient (10~20 ng/ml) in 13 patients (13.5%), relatively insufficient (21~29 ng/ml) in five patients (8.3%) and sufficient ((t ng/ml) in three patients (3.1%). Hyperbilirubinemia (${\geq}1.2g/dl$) was the only factor associated with severe vitamin D deficiency according to the multiple logistic regression analysis (Odds ratio, OR=18.48, P<0.05). Although hyperbilirubinemia showed a strong association with survival (Hazard ratio, HR=2.25, P<0.01), no association was found between severe vitamin D deficiency and survival (HR=1.15, P>0.05) in Cox's proportional hazard analysis. Conclusion: Although serum vitamin D levels were severely low in terminally ill cancer patients, we found no association between severe vitamin D deficiency and patient survival.

        The planning stage of an architectural project has much more significant effects on the cost or outcome of the project than other stages of the project. In addition, the importance of architectural planning has been further increasing according to the recent trend of construction projects becoming larger in scale and more complex. In spite of this, the current situation is that the planning stage work is not being systematically managed. Accordingly, the purpose of this study was to develop a BIM-based simulation system for providing support during architectural planning stage such as spatial planning & review, cost review, project owner requirements management, etc. It is easy to review various alternatives using this system that allows not only the modeling of space object modeling but also the instantaneous review of spatial area & layout, cost, etc. based on object information. In addition, it can be used as a communication tool with the project owner as it provides the visualized information and quantitative data of the building model, and the information created through this system can be delivered to the following stage for usage. It is thought that using this system, the entire project work including the architectural planning stage can be supported and even contributing to the advancement of architectural process. 건축 프로젝트의 기획단계는 타 단계에 비해 프로젝트의 비용이나 성과에 미치는 영향력이 매우 크다. 또한 최근 건설프로젝트의 대형화 복합화 추세에 따라 건축 기획의 중요성은 더욱 증가하고 있다. 그럼에도 현재 기획단계의 업무는 체계적으로 관리되지 못하고 있는 실정이다. 이에 본 연구는 공간계획 및 검토, 비용검토, 발주자 요구사항 관리 등의 건축기획단계 업무를 지원하기 위한 BIM 기반의 시뮬레이션 시스템을 개발하는 것을 목적으로 하였다. 본 시스템은 공간 객체의 모델링뿐만 아니라, 객체 정보를 기반으로 하여 계획의 변경에 따른 공간면적 및 배치, 비용 등을 즉각적으로 검토할 수 있어 여러 대안의 검토가 용이하다. 또한 건축물 모델의 시각화된 정보와 정량적인 데이터를 제공함으로써 발주자와의 의사소통 도구로 사용할 수 있으며, 본 시스템에서 생성된 정보를 후속 단계로 전달하여 활용이 가능하다. 시스템을 이용하여 건축기획단계를 비롯한 프로젝트 전체의 업무를 지원하고 나아가 건축 프로세스의 선진화에 기여할 수 있을 것으로 생각된다.

        스마트폰에서의 OTT(Over The Top)서비스 시청패턴 추적 어플리케이션 설계 : 티빙(tving)을 중심으로

        최선영,김민수,김명준,Choi, Sun-Young,Kim, Min-Soo,Kim, Myoung-Jun 한국정보통신학회 2014 한국정보통신학회논문지 Vol.18 No.4

        This study focuses on the fact that a OTT service is vigorously used for smart phones, and suggests a design of method to trace the experiences of watching television contents. For this purpose, we developed logging functions and embedded them into existing OTT service application to record flow and pattern of watching context. This paper suggests a log file format which can accurately and precisely record watching actions of users per-second methodology rather than former per-minute methodology. Moreover, this study shows that the application can trace watching attitude according to occurring events by characteristics and playing modes of realtime broadcasting, VOD, advertisement contents. In addition, based on the result of the study, this paper discusses educational, operational meaning of the method such as methodological application in mobile ethnography field or survey for total screening rate. 본 연구는 스마트폰에서 OTT 서비스 이용이 활성화되고 있는 것에 주목하여 텔레비전 콘텐츠 시청 행위 추적 방법의 설계를 제안한다. 이를 위해 기존 OTT서비스 어플리케이션을 활용하여 시청 맥락의 흐름(flow)과 패턴을 기록하는 로그 파일 기록 어플리케이션을 개발하였다. 본 논문에서 제시한 로그 파일 포맷은 기존의 분단위 시청률 조사방법이 아닌 초단위 측정으로 이용자 스마트폰을 통한 시청 행위와 시청 시간을 정확하고 정밀하게 측정할 수 있었다. 또한 실시간 방송 VOD 광고 콘텐츠 속성 및 플레이 모드에 따라 나타나는 시청 행태를 발생 이벤트에 따라 추적할 수 있었으며, GPS 데이터를 로그 파일 기록과 매칭한 결과 시청의 공간적 맥락을 분석할 수 있었다. 연구 결과를 바탕으로 패널을 이용한 통합시청률 조사 또는 모바일 민속지학(Mobile Ethnography) 에서의 방법론적 활용과 같은 학문적 실무적 의의를 논의하였다.

        최선영,최은숙,고광준,Choi Sun-Young,Choi Eun-Suk,Koh Kwang-Joon 대한영상치의학회 1998 Imaging Science in Dentistry Vol.28 No.2

        39-year-old female had been treated for the exophytic mass on buccal aspect of the left, maxillary posterior area 2 years and 8 months ago. Tentative diagnosis was obtained as fibrous dysplasia on clinical and radiographic examinations and histopathologic findings revealed as osteochondroma after bone trimming at that time. She revisited for the treatment of recurred lesions. We reviewed this case with clinical. radiologic and histopathologic standpoints retrospectively, and came to a conclusion that the tumor primarily occurred was juxtacortical osteogenic sarcoma and recurred due to inadequate treatment and then expanded over intramedullary. This case shows that the diagnosis of osteosarcoma should take account of the patient history, clinical. radiographic and histopathologic findings and it requires attentive follow up check. Retrospectively reviewed results were as follows ; At first visit, oral examination revealed a bony hard swelling on the buccal aspect of the left maxillary posterior area. Radiographically, a dense radiopaque mass was noted on the site. The lesion showed hot uptake of /sup 99m/Tc-MDP. Histopathologic diagnosis was done as osteochondroma, but it was considered as osteogenic sarcoma when compared with the recurrent lesion. When she revisited for the treatment of multiple bony swelling on the left maxilla, radiograms showed typical features of malignancy such as widening of periodontal ligament space and sunray appearace, and coincided with benign characters as follows; relatively well circumscribed lesion and expansion and displacement of the adjacent structures. Finally, histopathologic findings of the lesion was well differentiated chondroblastic osteogenic sarcoma.

        This report details a case of 8-year-old girl showing failure of odontogenesis after chemo-radiation therapy for the rhabdomyosarcoma at the age of 4. The observed results were as follows : 1. Past history revealed that she had received for a total radiation dose of 4430cGy, 29 fractions in 6 weeks and chemotherapy with vincristine, actinomycin D and cytoxan, followed as maintenance phase for 2 years. 2. The patient was symptom -free and appointed for the treatment of multiple dental caries. 3. Oral examination showed hypoplastic enamel on whole erupted permanent teeth and showed retarded eruption. 4. Conventional radiograms showed failure of root development including abrupt cessation of root formation and root agenesis, and microdontia, missing teeth, irregular enamel, dislocation of the impacted teeth. Additional finding showed good healing bone pattern on the left mandibular ramus and angle area. 5. Cephalometric analysis revealed failure of bite raising due to incomplete eruption of all the first molars and made it possible to suspect entrapped mandibular growth and then Class II tendency growth. 6. There was correlation between the time of chemo-radiation therapy and the damage of the teeth.

        제로기반 코드 변조 기법을 통한 비디오 핑거프린팅 시스템

        최선영,이해연,강인구,이흥규,Choi Sun Young,Lee Hae-Yeoun,Kang In Koo,Lee Heung-Kyu 한국정보처리학회 2005 정보처리학회논문지B Vol.12 No.4

        Digital fingerprinting is a contents-protection technique, where customer information is inserted into digital contents. Fingerprinted contents undergo various attacks. Especially, attackers can remove easily the inserted fingerprint by collusion attacks, because digital fingerprinting inserts slightly different codes according to the customers. Among collusion attacks, averaging attack is a simple, fast, and efficient attack. In this paper, we propose a video fingerprinting system that is robust to the averaging attack. In order to achieve code efficiency and robustness against the averaging attack, we adopt anti-collusion code (fingerprint code) from GD-PBIBD theory. When the number of users is increased, the size of fingerprint code also grows. Thus, this paper addresses a zero-based code modulation technique to embed and detect this fingerprint code efficiently. We implemented a blind video fingerprinting system based on our proposed technique and performed experiments on various colluding cases. Based on the results, we could detect most of colluders. In the worst case, our scheme could trace at least one colluder successfully. 디지털 핑거프린팅은 워터마킹 기술에 기반한 콘텐츠 보호 기술로 디지털 콘텐츠에 구매자의 정보인 핑거프린트를 삽입하는 기술을 말한다. 콘텐츠 안에 삽입된 핑거프린트 정보는 다양한 공격을 받게 된다. 특히 동일한 콘텐츠 안에 서로 다른 구매자의 정보를 넣게 되는 핑거프린팅의 특성으로 인해 공모 공격이 가능하고, 그 중 평균화 공격은 빠르고 효과적인 공모 공격에 해당한다. 본 논문에서는 평균화 공격에 강인한 비디오 핑거프린팅 시스템을 제안한다. 공모 공격 후에도 특정 위치의 코드 값이 원래의 값을 유지할 수 있는 공모 방지 코드를 적용하였다. 또한 사용자의 수가 늘어남에 따라 핑거프린트 코드의 길이가 증가하는데 이와 같은 코드의 효율적인 삽입 및 검출을 위해 제로기반 코드 변조 기법을 적용함으로써 올바른 공모자 추적이 가능하도록 하였다. 제안한 방식을 사용하여 원본 비디오를 사용하지 않는 비디오 핑거프린팅 시스템을 구현하였고, 다양한 공모자의 수에 따른 실험을 수행하였다. 실험 결과에 따르면 대부분의 경우 공모자를 올바르게 추출할 수 있었고, 최소 한 명 이상의 공모자를 성공적으로 검출할 수 있었다.

        최선영,고광준,Choi Sun-Young,Koh Kyang-Joon 대한영상치의학회 2003 Imaging Science in Dentistry Vol.33 No.1

        Purpose: To investigate the effects of irradiation on the phenotypic expression of the MC3T3-El osteoblastic cell line, particularly an the expression of type I collagen and alkaline phosphatase mRNA. Materials and Methods: Cells were irradiated with a single dose of 0.5, 1, 2, 4, and 8 Gy at a dose rate of 5.38 Gy/min using a cesium 137 irradiator. The specimens were then harvested and RNA extraction was carried out at 1 and 3 days after irradiation. The extracted RNA strands were reverse-transcribed and the resulting cDNA fragments were amplified by PCR. Results: The irradiated cells demonstrated a dose-dependent increase in type I collagen mRNA expression relative to the control group, with a maximum level of type I collagen mRNA expression occurring at 8 Gy. The degree of type I collagen mRNA expression increased significantly at 1 day after irradiation, but little differences were found between the control group and at the 3rd day. The amount of alkaline phosphatase mRNA expression increased significantly at land 3 days after irradiation in the 1 Gy exposed group compared with the control group. Conclusion: The amount of type I collagen and alkaline phosphatase mRNA expression increased significantly 1 day after irradiation when compared with the control group.

        토양수분(土壤水分)포텐셜이 고추냉이의 기공전도도(氣孔傳導度)와 광합성(光合成)에 미치는 영향(影響)

        최선영,이강수,Choi, Sun-Young,Lee, Kang-Soo 한국약용작물학회 1996 韓國藥用作物學會誌 Vol.4 No.4

        본(本) 연구(硏究)는 고추냉이의 밭재배에 있어서 관개계획(灌漑計劃)에 필요한 기초자료를 얻고자 단수처리(斷水處理)동안 기공전도도(氣孔傳導度)와 광합성(光合成), 그리고 토양수분포텐셜을 조사하였다. 1. 고추냉이의 기공전도도(氣孔傳導度)는 광도(光度) $1000{\mu}Em^{-2}s^{-1}$에서 $70mmolem^{-2}s^{-1}$로 배추의 $138mmolem^{-2}s^{-1}$보다 약 49%가 낮았으며, 낮동안 일시적인 광도(光度)의 변화에는 별다른 영향을 받지 않았다. 2. 고추냉이의 기공전도도(氣孔傳導度)가 감소(減少)하는 토양수분포텐셜은 오전(午前) 10시(時)에는 약 -50kPa, 오후(午後) 3시(時)에는 약 -30kPa로 오전(午前)보다 오후(午後)에 높았다. 3. 고추냉이의 광합성(光合成)은 광도(光度) $1000\;{\mu}Em^{-2}s^{-1}$에서 $7.6mgdm^{-2}hr^{-1}$으로 배추의 $15.3mgdm^{-2}hr^{-1}$보다 약 50%가 낮았으며 광합성(光合成)이 안정되기 까지의 시간은 배추보다 고추냉이가 더 낮았다. 4. 고추냉이의 광합성(光合成)이 감소(減少)되 는 토양수분포텐셜은 오전(午前) 10시(時)에는 약 -50kPa, 오후(午後) 3시(時)에는 약 -30kPa로 오전(午前)보다 오후(午後)에 높았으며 토양수분포텐셜에 따른 광합성(光合成)과 기공전도도(氣孔傳導度)와의 상관관계는 고도의 유의성 (r=0.955)이 인정되었다. 5. 고추냉이의 관개시기(灌漑時期)는 낮동안의 기공타도도(氣孔惰導度)와 광합성(光合成)이 감소(減少)되지 않는 토양수분포텐셜 -30kPa 이상일 때가 바람직하다. This study was investigated to obtain basic information for the development of irrigation plans in upland cultivation of Wasabi. Changes of stomatal conductivity and photosynthetic rate of Wasabi, and of the soil water potential during withholding watering were analysed. The stomatal conductivity of Wasabi at $1000{\mu}Em^{-2}s^{-1}$ light intensity was $70mmolem^{-2}s^{-1}$, which was about 49% lower than that of Chinese cabbage, $138mmolem^{-2}s^{-1}$. The temporal changes of light intensity during the daytime did not influence the stomatal conductivity. The soil water potential that decreased stomatal conductivity in Wasabi was about - 50kPa at 10 AM, and about - 30kPa at 3 PM. The photosynthetic rate of Wasabi at$1000{\mu}Em^{-2}s^{-1}$ light intensity was $7.6mgdm^{-2}hr^{-1}$, which was about 50% lower than that of Chinese cabbage, $15.3mgdm^{-2}hr^{-1}$. The duration required for a stable photosynthetic rate was longer in Wasabi than in Chinese cabbage. The soil water potential that decreased photosynthetic rate in Wasabi was about - 50kPa at 10 AM, and about - 30kPa at 3 PM. The stomatal conductivity and photosynthetic rate showed significant positive correlation at various soil water potential. The results indicated that irrigation in wasabi could be done during the daytime when the soil water potential is above - 30kPa, which does not decrease stomatal conductivity and photosynthesis in Wasabi.
