Purpose: The study was performed to compare patients with anatomical variations in facial asymmetry with patients in the normal range using cone-beam computed tomography (CBCT) and to take the preoperative condition into consideration in the case of a sagittal split ramus osteotomy (SSRO). Methods: The study was conducted on 46 adult patients composed of 2 subdivided groups, an asymmetry group (n=26) and a symmetry group (n=20). The asymmetry group was divided between patients with hemimandibular hyperplasia (HH, n=8) and hemimandibular elongation (HE, n=18). Using cross-sectional computed tomography images, the thickness of cancelleous bone in the buccal area of the mandible, thickness of buccal cortex in the buccal aspect of the mandible, thickness of cancellous bone in the inferior aspect of the mandible, thickness of buccal cortex in the inferior aspect of the mandible, and cross-sectional surface area of the mandible were measured. Results: In the asymmetry group, the cross-sectional area of the mandible including the inferior alveolar nerve positioned on the affected side was significantly different from the symmetry group. Thickness of cancelleous bone in the buccal aspect of the mandible, thickness of cancelleous bone in the inferior aspect of the mandible, and cross-sectional surface area of the mandible in the affected site of hemimandibular hyperplasia was significantly smaller than in the symmetry group. Conclusion: The inferior alveolar nerve runs lower and in a more buccal direction and shows a smaller cross-sectional surface of the mandible in the hemimandibular hyperplasia patients with asymmetry.

분쟁광물이란 특히, 콩고민주공화국(DRC)의 동부지역과 같이 분쟁지역에서 채굴되는 광물에 대하여 부르는 용어이다. 보통 분쟁광물이란 주석, 콜탄(컬럼바이트-탄탈라이트), 중석, 금과 같은 광물로 주로 콩고민주공화국(DRC)의 동부지역에서 채굴되고 있는 광물로서, 이러한 분쟁광물은 여러 가지 전자기기의 제조에 사용되고 있다. 콩고민주공화국(DRC)과 이웃 나라에서 분쟁을 종식시키기 위해 자금원이 되어왔던 분쟁광물의 개발이나 교역의 근원을 차단시키고 분쟁국에 있어서 무장그룹에 의한 분쟁을 억제시킬 필요가 있다. 미국 증권거래위원회(Securities and Exchange Commission, SEC)는 2012년 8월 22일 금융규제개혁법 제 1502조에 근거하는 규칙을 채택하였는데, 이 법에 따라 미국 기업들은 증권거래위원회에 분쟁광물을 이용하여 제품을 생산할 경우 분쟁광물의 원산지에 대한 보고를 하여야 한다. 이 법은 분쟁 광물의 원산지를 추적하여 특히, 분쟁 광물의 자금원이 되고 있는 콩고 민주공화국을 필두로 분쟁국에 있어서의 무장세력의 직 간접 자금원을 끊어 분쟁을 억제하는 것을 그 목적으로 하고 있다. Conflict minerals refer to minerals mined in conditions of armed conflict, especially as in the eastern provinces of the Democratic Republic of the Congo. The common conflict minerals are cassiterite, wolframite, coltan(columbite-tantalite ore), and gold, which are mined and extracted from the Eastern Congo. These minerals are essentially used in the manufacture of a variety of devices, including consumer electronics. To end the violent conflict in the Democratic Republic of the Congo (DRC) and in surrounding countries, it is necessary to block the supply route of conflict minerals which has been partially financed by the exploitation and trade of conflict minerals. The Dodd-Frank Wall Street Reform and Consumer Protection Act, passed into law in July 2010 and it contains requirements that U.S. companies report to the Securities and Exchange Commission(SEC) on the origin of conflict minerals and show due diligence of OECD. The goal of the act is to cut direct and indirect funding of armed groups engaged in conflict.

박성원,전재호,박주용,최성원,김수호,Park, Sung Won,Jeon, Jae Ho,Park, Joo Yong,Choi, Sung Weon,Kim, Soo Ho 대한악안면성형재건외과학회 2012 Maxillofacial Plastic Reconstructive Surgery Vol.34 No.6

Schwannoma is a benign, slow-growing, tumor of the peripheral nerves without specific symptoms, so that early diagnosis may be difficult. Though approximately 25~40% of all schwannomas occur extracranially in the head and neck region, only 1% of schwannomas are reported in the oral cavity. An 18-years-old female patient visited our clinic with a mass on the middle-right-dorsal surface of the tongue slowly growing for 1.5 years. The patient underwent the surgical removal of the neoplasia under general anesthesia. The mass was well capsulated and a cleavage plane was easily found. There was no recidivation during the course of a one-year follow-up. The treatment for schwannoma is surgical excision of the lesion and recurrence after excision of schwannoma is rare. The final diagnosis is made after a histological examination. Differential diagnoses must be made in relation to malignant tumors and in relation to numerous benign neoformations based on epithelial and connective tissues.

General behaviors based on hydraulic characteristics of natural streams and channels have been recently analyzed and developed via various numerical models. However in the states of natural hydraulics, an experimental research must be performed simultaneously with the mathematical analysis due to effects of hydraulic properties such as meander, sediment, and so on. In this study based on 2-D advection-dispersion equation, flow and tracer experiments were performed in the S-curved meandering laboratory channel with a rectangular cross-section. The channel was equipped with instrument carriages which was equipped with an auto-traversing system to be used with velocity measuring sensors throughout the depth and breadth of the flow field. To measure concentration distribution of the salt solution was adjusted to that of the flume water by adding methanol and a red dye (KMnO4) was added to aid the visualization of the tracer cloud, the tracer was instantaneously injected into the flow as a full-depth vertical line source by the instantaneous injector and the initial concentration of the tracer was 100,000 mg/l. The secondary current as well as the primary flow pattern was analyzed to investigate the flow distribution in the meandering channels. The velocity distribution of the primary flow for all cases skewed toward the inner bank at the first bend, and was almost symmetric at the crossovers, and then shifted toward the inner bank again at the next alternating bend. Thus, one can clearly notice that the maximum velocity occurs taking the shortest course along the channel, irrespective of the flow conditions. The result of the tracer tests shows that pollutant clouds are spreading following the maximum velocity lines in each cases with various mixing patterns like superposition, separation, and stagnation of pollutant clouds. Flow characteristics in each cases performed in this study can be compared with tracer dispersion characteristics with using evaluation of longitudinal and transverse dispersion coefficients(LDC, TDC). As expected, LDC and TDC in meandering parts have been evaluated with increasing distribution and straight parts have effected to evaluate minimum of LDC and TDC due to symmetric flow patterns and attenuations of secondary flow.

박성원(Park Sung Won),김상민(Kim Sang Min),정재훈(Jung Jae Hun),김창재(Kim Chang Jae),허준(Heo Joon) 대한공간정보학회 2010 한국지형공간정보학회 학술대회 Vol.2010 No.3

세계적으로 열적외선을 활용한 위성영상 및 항공영상은 다양한 분야에서 활용되어지고 있다. 현재 국내에서는 이를 제공할만한 적외선 관측위성이 부재하고 활용방안에 대한 연구도 초기단계여서 실제적으로 사용하는 경우는 드물다. 그러나 이를 상용화하고 활성화하는 것이 다양한 분야에서 새로운 이익을 창출해줄 것이라 판단된다. 가까운 미래에 국내의 위성에도 적외선 위성 센서가 탑재될 것이다. 이에 대한 활용방안 연구는 자체의 의미에 더하여 적외선 위성 사업의 필요성을 촉진하고 활성화 하는데 기여할 것이다. 본 논문에서는 열적외선 위성영상 중 중적외선(MWIR, 3~8㎛)을 중심으로 하여 세계 각 국의 할용 방안을 살펴보고 국내의 활용실태와 비교하여 도입 가능한 부분을 예측하고 필요성을 검토할 것이다.

박성원(Sung Won Park),민성길(Sung Kil Min),김소야자(Soyaja Kim,R.N. ) 대한사회정신의학회 2002 사회정신의학 Vol.7 No.2

목 적: 본 연구는 정신분열병 환자가 지각한 가족의 표출감정과 환자의 사회적응 및 가족부담감의 정도를 주관적으로 평가하고, 그 상관관계를 규명하기 위한 것이다. 연구방법: 정신분열병 환자 81명에게 한국판 Level of Expressed Emotion(K-LEE)과 Social Adjustment Scale을 평가하게 하였고, 그들의 주요 가족 81명에게 가족의 부담 척도를 평가하게 하였다. 그 결과 얻은 전체 표출감정과 사회적응, 가족부담의 관계를 Pearson’ s correlation으로 분석하였다. 연구결과: 환자가 지각한 가족의 총 표출감정 평균 점수는 11.58±2.20 이었고, 가족 부담감의 전체 문항평균은 1.20±.67이었으며 환자의 사회적응 전체 문항 평균은 2.50±0.63 이었다. 가족의 표출감정, 환자의 사회적응, 가족부담감 척도들의 점수간에는 통계적 으로 유의한 상관관계가 나타나지 않았다. 그러나 하위영역들 간의 상관관계에 있어서는, 가족의 지지가 부족할 수록 환자의 사회적응 장애가 심한 것으로 나타났다. 또한 가족의 간섭이 심할 수록 환자의 사회관계 및 여가활동에서의 역할, 핵가족에서의 역할, 및 직업생활에서의 역할에서 유의하게 장애가 있는 것으로 나타났다. 또한 환자가 지각한 가족의 비난이 클수록 가족의 객관적 부담감과 주관적 부담감이 유의하게 컸다. 결 론: 이러한 결과는 가족들이 정신분열병 환자의 사회적응을 돕고 가족 자신들의 부담을 줄이기 위해 지지는 강화하고 간섭은 줄이며 비난을 삼가야하여야 함을 시사한다. Object:This study was to study correlation between schizophrenic patients’ subjectively perceived expressed emotion by family and their social adjustment and perceived burden of family. Method:Subjects were 81 schizophrenic patients and their family. Patients rated Korean version of Level of Expressed Emotion(K-LEE) and Social Adjustment Scale. Their family rated a Scale for Family Burden. Collected date were analysed with Pearson correlation test. Results:Mean total score of K-LEE, Scale for Family Burden and Social Adjustment were 11.58±2.20, 1.20±.67 and 2.50±0.63 respectively. There was no significant correlation among them. However among subscales, there were some significant correlations. The less family support was and the more severe intervention of family was, the poorer were patients’ social relationship, leisure activities, functions in extended family and functions in occupational life. And the severer patients perceived family’s blaming was, the greater family’s subjective and objective burden were. Conclusion:These results suggest that, for patients, better social adjustment, family have to provide more support, reduce intervention and restrain blaming.

애니메이션 몽타쥬로 표현된 시간의 주관성 연구

박성원(Park, Sung Won) 한국디지털디자인협의회 2015 디지털디자인학연구 Vol.15 No.3

본 연구는 애니메이션의 서사표현 있어서 중요한 문법요소인 몽타쥬의 양상을 분석해보고 시간적 특징을 분석의 틀로 분석한 논문이다. 애니메이션은 영상예술로서 시간성을 갖는다. 시간성은 내러티브 구조로 표현되며 이를 효과적으로 전달하는 문법으로서 몽타쥬가 사용된다. 즉, 애니메이션은 영화와 같이 서사구조를 통해 감독의 연출적 관점을 전달한다. 따라서 애니메이션사의 초기에서부터 현재까지 장르와 기법을 막론하고 시네마적 기법의 몽타쥬가 적용되어 왔다. 그러나 영화작품에 대한 비평적 관점의 한 축으로 오랫동안 존재해온 몽타쥬 연구에 비해 애니메이션작품에 대한 비평적 몽타쥬 연구는 미미한 것이 사실이다. 따라서 본 연구는 몽타쥬 구조적 배치가 중요한 요소가 되는 단편 애니메이션을 대상으로 하여 서사 분석의 주요 요소들을 알아보고 시간성을 관점으로 한 몽타쥬 특성을 분석하여 서사 전달의 필연적 관점을 제공하는 틀을 마련하고자 한다. 분석을 통해 정리된 관점은 다음과 같다. 애니메이션에서는 기획한 의도와 관람하게 될 대상, 매체의 특성, 그리고 연출자의 개성이 영상적 문법을 결정하는 요인으로 작용한다는 것이다. 몽타쥬를 결정짓는 성격으로는 시간이라는 개념으로 이는 객관적시간과 주관적시간으로 분류할 수 있다. 또한 애니메이션 Paper man에서는 심리적 시간성이 적스타포지션(Juxtaposition)과 듀레이션(Duration)이라는 몽타쥬 구조안에 표현되고 있음을 알 수 있다. 또한 객관적 시간성을 표현하기위해 특정 시퀀스에서는 카메라 유도에 의한 롱테이크 방식을 적용하고 있음이 분석되었다. This study is the analysis of montage, an important grammatic element in narrative expression of animation, and its time characteristics. Animation is video art, and it has time characteristics. Time characteristics is expressed as narrative structure, and montage is used as a grammar to express it effectively. That is, animation delivers productive perspective of the director through narrative structure as in the case of movie. Consequently, montage of cinematic technique has been used from the beginning of the history of animation, regardless genres and techniques. But, while the research on montage has long existed on the movie as part of movie review, there has been little critical research on animation montage. Accordingly, this research, using short animation where structural arrangement of montage is an important element, will examine important elements in narrative analysis, analyze montage characteristics based on time characteristics, and prepare a frame which provide an inevitable perspective in delivering narrative. The perspective drawn from the analysis is as follows: in animation, planned intention, objects to watch, characteristics of media, and personality of producer work as elements in deciding video grammar. What determines montage is the concept of time, and time can be divided into objective time and subjective time. And, we can recognize that, in the animation "Paper Man", psychological time is expressed in the montage time called juxtaposition and duration. It was also analyzed that, to express objective time, camera-led long-take method is applied in a specific sequence.
