          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.

          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.

          최선영,임숙영,고광준,Choi Sun-Young,Lim Sug-Young,Koh Kwang-Joon 대한영상치의학회 1999 Imaging Science in Dentistry Vol.29 No.2

          Objectives : The purpose of this study is to evaluate the computed tomographic (CT) images of the paranasal sinusitis(PNS). Materials and Methods : The author examined the extent and recurring patterns of the paranasal sinusitis and some important anatomic landmarks. The author analyzed PNS images retrospectively in 500 patients who visited Chonbuk National University Hospital between January 1996 and December 1997. Results : The most frequently affected sinus was maxillary sinus (82.9%), followed by anterior ethmoid sinus(67.9%), posterior ethmoid sinus(48.9%), frontal sinus(42.0%) and sphenoid sinus(41.4%). The characteristic features of CT images of the sinusitis were sinus opacification(22.4%), mucoperiosteal thickening(34.3%), and polyposis(2.0%). Sinonasal inflammatory diseases were categorized into 5 patterns according to Babber s classification. They were 1) infundibular(13.0%), 2) ostiomeatal unit(67.4%), 3) sphenoethmoidal recess (13.0%), 4) sinonasal polyposis (9.6%) and 5) unclassifiable patterns(18.0%). The incidences of contact between sinus and optic nerve were as follows ; the incidences of contact with posterior ethmoid sinus, sphenoid sinus. both posterior sinuses were 11.4%. 66.8%, 6.3%. respectively. The incidences of contact between sphenoid sinus and maxillary nerve, vidian nerve, internal carotid artery were 74.5%. 79.2%. 45.1%. respectively. The incidences of pneumatization of the posterior ethmoid sinus were as follows ; normal 70.6% and overriding type 29.4%. The incidences of sphenoid sinus pneumatization were as follows; normal 56.9% , rudimentary 12.5%, pterygoid recess 22.7%, anterior clinoid recess 2.7%, and both pterygoid and anterior clinoid recess type 5.2%. Conclusions : The inflammatory sinonasal diseases were classified into five patterns using the CT of PNS, which was proven to be an excellent imaging modality providing detailed information about mucosal abnormality, pathologic patterns, and the proximity of the important structures to the posterior paranasal sinuses. This result will aid in the interpretation of CT of PNS functionally and systemically.

          상악골에 발생된 연골형성현 측피질골육종

          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.

          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.

          This study is performed to estimate the prevalence of metabolic syndrome among male workers and to identify the relationships with many related factors including anthropometry, hematological index, serum lipid level, dietary-related behaviors and health-related behaviors. According to the age groups, the 20s are significantly higher in normal and risk groups than in the metabolic syndrome (MS) group, the 30s are significantly higher in MS group than the other groups. The levels of AST and ${\gamma}$-GTP both show significant differences in the order of MS group ($30.3{\pm}8.8U/l$, $91.1{\pm}40.2U/l$) > risk group ($25.7{\pm}8.1U/l$, $41.8{\pm}20.2U/l$) > normal group ($22.8{\pm}6.0U/l$, $26.6{\pm}10.7U/l$). For the frequency of breakfast consumption, the response of 'Every day' is significantly higher in MS group than normal and risk groups, but the response of 'Not at all' is significantly higher in normal group than MS and risk groups. The drinking amount is positively correlated with ${\gamma}$-GTP in normal group, and it is negatively correlated with the hematocrit level, but it is positively correlated with the systolic blood pressure in MS group. AST is positively correlated with glucose concentrations of the MS group. The ALT is positively correlated with waist circumferences and systolic blood pressure in the risk group. The results of this study show that breakfast frequency, education level, drinking amount, drinking frequency, exercise frequency, AST, ALT and ${\gamma}$-GTP levels are all important risk factors of MS. Therefore, it is very important to maintain a healthy life style for the prevention of MS incidence.

          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.

        • 해수침투 조사자료의 통합적 해석을 위한 GIS의 적용

          최선영,황세호,박권규,신제현,윤왕중,Choi Sun-Young,Hwang Seho,Park Kwon Gyu,Shin Je-Hyun,Yoon Wang-Jung 한국공간정보학회 2004 한국공간정보학회지 Vol.12 No.3

          국내 연안지역에서 광범위하게 발생하고 있는 해수침투를 정확하게 평가하고, 이에 대한 대책을 수립하기 위해서는 다양한 분야의 연구와 이들 상호간의 자료 통합과 유기적인 해석은 매우 중요하다. 현재 수리지구화학, 지구물리탐사 및 수리지질 등의 다양한 분야에서 해수침투 연구를 수행하고 있지만, 이들 자료의 공유나 체계적인 관리분야는 초보적인 수준으로 다양한 자료에 대한 검색과 관리가 어려울 뿐만 아니라, 자료를 통합하여 해석하는데 어려움이 따른다 따라서 본 연구에서 정밀조사 지역인 전남 영광군 백수읍 일대에서 획득하고 분석한 지표 및 시추공 물리탐사자료와 수리지화학자료를 데이터베이스로 구축하고, ArcView 스크립트어인 Avenue를 이용하여 데이터베이스 관리 및 시추공 3차원 가시화 인터페이스를 개발하였다. 이와 같은 지리정보시스템(GIS; Geographic Information System) 기반의 데이터베이스 구축과 사용자 인터페이스 개발로 다양한 종류의 해수침투 조사자료를 효율적으로 관리하고 통합할 수 있기 때문에 보다 정확하고 종합적인 분석이 가능할 것이다. In order to effectively, and accurately assess seawater intrusion in coastal area, multidisciplinary data including geophysical, well logging, and hydrogeochemical data should be managed in systematical way. Such systematical management of data is critical key to improve the re-usability of the data as well as the accuracy of the assessment by means of providing a method of synthetic analysis. Therefore, for systematical management of multidisciplinary data in seawater intrusion problem, we have developed a database management system and 3-D visualization interface based on geographic information system in this, study. All geophysical survey, well logging, hydrochemical, as well as drilling, data are classified as attribute data using Microsoft Access, and joined with spatial information based on ArcView. The database management system and 3-D visualization interface to handle these data, also, developed using the script language of ArcView. We think the development of database and 3-D visualization system will improve the efficiency of data management, user-friendliness of data access, and accuracy of data analysis.

          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.
