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.

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.

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.

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.

극장판 애니메이션의 엔딩 크레딧 양상연구: 쿠키 영상을 중심으로

박성원(Sung-Won Park),이혜원(Hye-won Lee) 한국데이타베이스학회 2020 Journal of information technology applications & m Vol.27 No.1

With the development of technology and the creation of an entertainment environment for leisure, various marketing strategies are being used in the film industry. Among them, the use of the credit cookie of ending credits was very effective in producing the series. The ending credit is the time it takes to show the names of the people who made the movie, which is meaningless to the audience. There is a cost to produce a ending credit but It wasn"t made because no revenue was generated. The credit cookie was inserted into this ending credit area, which brought new pleasure to the audience. Most of them were epilogue images showing the story behind the movie, NG images showing the NG situation during film production, and In videos mentioned in the movie but not shown in the movie itself. As various ideas about credit cookie were connected with marketing, a series movie and a spin-off foretelling the derivative works after the screening work were produced and have a new meaning. As a result, the time of ending credits, which had no commercial value, became the methodology of the most powerful promotional strategy. Looking at the difference between live-action film and animation in producing such credit cookie, unlike live-action films that edit the remaining parts after shooting, the NG video of the animation has a lot of time and money to produce. So, it hasn"t try very well, and it seems to have been actively produced when moving from 2D animation to 3D animation. This is because 3D animation, which has already been modeled, can create new NG scenes by simply adding animating based on the layout of the created scene. Since it is possible to produce an episode movie at a low cost and time, and to use the scenes of the movie after the production, it will be necessary to strategically produce credit cookie for promotion in animation.

20세기 이후 우리의 경우는 숨가쁘게 유입되는 세계문화와 기존 우리 문화와의 소화 불량적 만남으로 혼돈의 문화를 이룩하였으며, 반도체 수출이나 IT산업에 있어서, 최강의 기술력 보유국(保有國)이라는 자리를 점유하면서도 공허한 심정을 떨칠 수 없게 되었다. 그러한 한국의 현대사와 동시대적 상황 가운데 작금의 현실을 살아가는 우리들은 정치적, 사회적, 문화적 측면에서 혼돈과 현기증을 복합적으로 체감하게 된다. 대중화(大衆化), 소비화(消費化)된 사회는 경제력 향상을 초래(招來)하였으나 그 출발은 익명(匿名)의 대중출현에 의해 가능했으며, 군중(群衆) 속에서의 고독, 소외(疏外), 익명성(匿名性), 몰개성성(沒個性性), 문화의 상품화(商品化) 등의 삶을 동반하고 있다.<br/> 본인의 작품에는 이와 같은 사회 현상(現想)들이 도시적 인간상을 통해 드러난다. 소비문화에 노출된 채 그것이 내뿜는 시각 이미지와 유혹에 포위되어 살아가는 인간은 끊임없는 소유욕(所有慾)에 둘러싸여 자신의 가치를 높이기 위한 모든 것을 공간 안에 가둔다. 이들은 몰개성화된 모습으로 때로는 동물인지 사람인지 알아볼 수 없는 형상으로 도시의 공간에 존재한다. 이는 산업화된 도시의 파괴되어가는 자연 환경을 고발하기 위한 하나의 상징체(象徵體)로서 인간의 소유욕(所有慾)안에 속해있는 제 3의 존재이며 도심속에 갇혀 사는 우리들의 초상화(肖像畵)인 것이다.<br/> 본인은 위와 같은 형상을 통하여 현대 도시문명의 현실 속을 살아가는 인간의 객관적 삶과, 익명성(匿名性)에 묻혀 표현되지 못한 욕구와 감정의 대립을 분석해 봄으로써 우리들이 가져야 할 자생성(自生性)과 정체성(停滯性)을 제시하고자 한다. It works as intermediation of communication of publics these days. Since 20 century, We, Koreans, have established new chaotic multi culture with traditional Korean culture and other different culture from everywhere. Meanwhile, we occupied the most powerful semi-conduct and IT industry.<br/> Within those circumstance, people feel very confused in political, cultural and social aspect. The society armed with economy and popularization promotes material satisfaction with this potential possibility of anonymous masses. However, it results to cause loneliness, isolation, alienation, anonymity, non individuality and commodity of culture.<br/> In my work, such phenomenon reveals through human character in a city. People are exposed culture of consumption and surrounded and tempted by all those artificial and superficial atmosphere.<br/> Human are possessed and exposed to attractive products and visual images. Finally they make themselves stuck in their case of this world. People lose their own identify and shape of bodies.<br/> That is our portrait, who are living this moment. Also, this is a symbol that destroys this modem society.<br/> As a result, I consider such aspects through those elements above to think how to keep and rethink our identity and what to do for this world.
