애니메이션 콘텐츠는 매년 꾸준히 성장하며 발전되고 있지만 아직까지 하나의 애니메이션 콘텐츠를 제작하기 위한 제작 기간 및 예산은 부족한 실정이다. 특히 TV 시리즈 애니메이션의 경우 짧은 제작 기간 안에 많은 편수의 영상을 제작해야 하다보니 풀 3차원 애니메이션을 제작 방식을 택하는 경우가 많다. 그러나 풀 3차원 애니메이션 또한 고품질의 배경을 제작하고, 렌더링 하는 데에 많은 시간을 필요로 한다는 점에서 또 다른 문제가 발생한다. 그래서 이를 보완하고자 하는 제작 방법이 합성 애니메이션이다. 컴퓨터 그래픽(CG) 캐릭터와 실사 배경을 합성하여 애니메이션을 제작하는 방법으로, 풀 3차원 애니메이션 방식에 비해 필요한 인력이 상대적으로 적어 효율적인 구조에서 자연스러운 영상 제작이 가능하며 렌더링 시간을 줄일 수 있다는 장점을 가진다. 본 논문은 미니어처 세트와 3차원 컴퓨터 그래픽을 이용한 효율적인 합성 애니메이션 제작 공정을 제시하고자 한다.

Background: To evaluate the clinical outcomes and associated repair integrity in patients treated with arthroscopic repair for a transtendinous rotator cuff tear followed by resection of the remnant rotator cuff tendon. Methods: Between July 2007 and July 2011, we retrospectively reviewed patients who were treated for transtendinous full-thickness tears in the tendinous portion of the rotator cuff by arthroscopic repair. Clinical outcomes were evaluated using the American Shoulder and Elbow Surgeons (ASES) score, the Shoulder Rating Scale of the University of California at Los Angeles (UCLA), the Constant-Murley score, a visual analogue scale (VAS) pain score, and range of motion (ROM). The repair integrity was determined by magnetic resonance imaging or ultrasonography. Results: There were 19 shoulders with transtendinous full-thickness tears in the tendinous portion of the rotator cuff. The ASES, UCLA, Constant-Murley, and VAS pain scores showed significant improvements in function and symptoms (all p<0.001). The active ROM for forward flexion and abduction was also significantly improved (p=0.002 and p<0.001, respectively). The postoperative radiological examination showed cuff integrity without a re-tear in 68.4% of patients. However, the UCLA, ASES, and Constant-Murley scores were not significantly different between healed and re-torn group (p=0.530, p=0.885, and p=0.262, respectively). Conclusions: Although repair of transtendinous rotator cuff tears followed by resection of the remnant rotator cuff tendon in the footprint has a relatively high re-tear rate, no significant difference was observed in the short-term clinical results between the re-tear and healed groups.

UCP 500 has introduced new words "International Standard Banking Practice" as the basis of the examination of documents under documentary credits. However, the words have caused confusion among parties concerned with letter of credits. So, at its May 2000 meeting, ICC Banking Commission established a task force to document international standard banking practice for the examination of documents presented under documentary credits(ISBP). The publication is the product of two and a half years of work by a task force of the ICC Banking Commission. It was approved by the full Commission at its meeting in Rome in October 2002. The ISBP is a practical complement to UCP 500. It explains how the rules are to be applied on a day-to-day basis. As such, it fills a needed gap between the general principles announced in the rules and the daily work of the documentary credit practitioner. But, ISBP have two problems. First, ISBP impose more responsibilities than before the ISBP existed on banks. Second, ISBP have some problematic articles like the problem of maturity, letter of credit language, term. Consequently, all parties concerned with documentary credits need to armour themselves with knowledge for ISBP. Also, it should be noted that any term in a documentary credit which modifies or affects the applicability of a provision of the UCP may also have an impact on international standard banking practice. Therefore, in considering the practices described in this publication, parties must take into account any term in a documentary credit that expressly excludes or modifies a provision in an article of the UCP.

This study aimed at developing a generalized model on the estimation of the long - term run - off volume for practical purpose. During the research period of last 3 years( 1986-1988), 3 types of estimation model on the long - term run - off volume(Effective rainfall model, unit hydrograph model and barne's model for dry season) had been developed by the author. In this study, through regressional analysis between determinant factors (bi of effective rainfall model, ai of unit hydrograph model and Wi of barne's model) and catchment characteris- tics(catchment area, distance round the catchment area, massing degree coefficient, river - exte- nsion, river - slope, river - density, infiltration of Watershed) of 11 test case areas by multiple regressional method, a new methodology on the derivation of determinant factors from catchment characteristics in the watershed areas having no hydrological station was developed. Therefore, in the resulting step, estimation equations on run - off volume for practical purpose of which input facor is only rainfall were developed. In the next stage, the derived equations were applied on the Kang - and Namgye - river catchment areas for checking of their goodness. The test results were as follows ; 1. In Kang - river area, average relative estimation errors of 72 hydrographs and of continuous daily run - off volume for 245 days( 1/5/1982 - 31/12) were calculated as 6.09%, 9.58% respectively. 2. In Namgye - river area, average relative estimation errors of 65 hydrographs and of conti- nuous daily run - off volume for 2fl days(5/4/1980-31/12) were 5.68%, 10.5% respectively. In both cases, relative estimation error was averaged as 7.96%, and so, the methodology in this study might be hetter organized than Kaziyama's formula when comparing with the relative error of the latter, 24~54%. However, two case studies cannot be the base materials enough for the full generalization of the model. So, in the future studies, many test case studies of this model should he carries out in the various catchment areas for making its generalization.

이주여성의 증가는 한국사회에 많은 영향을 미치고 있지만, 적절한 사회프로그램이 제공되지 못하고 있는 상황이다. 최근 이주여성은 사회적 약자의 위치에서 벗어나 자신의 문화를 지키고 스스로의 역량을 강화해 나가는 새로운 집단으로 부각되고 있다. 따라서 디아스포라의 함의를 포함하여 문화절충과 소수집단의 역량을 강화하는 측면에서 장기적이면서 비차별적인 사회프로그램의 개발이 시급한 상황이다. 본 논문에서는 이주의 역사가 오래된 EU의 이주여성을 위한 사회프로그램을 분석하여 앞으로의 사회프로그램개발에 기여하고자 하였다. EU자료분석은 인터넷자료와 EU Commission의 공식자료를 주로 분석하여 표로 재구성하였다. EU 사회프로그램의 특징은 비차별, 완전 고용, 인권과 시민권을 기반으로 구성되었다는 것이고, 사회적배제의 차원이 아니라 사회포용정책의 일환으로 제공되고 있다. 단기간의 전시성 프로그램이 아니라 장기적으로 완전고용을 통한 시민권 보장을 위한 프로그램이 준비되는 것이 사회통합차원에서 필요할 것이다.

Recently, there has been inter-Korean exchanges are active, in company with an assertive international activity with North Korea and inter-Korean Summits. Thus, there is a growing possibility of Korean reunification. However, when the unification situation occurs, population inflow by North Korean residents will be expected, and it will be necessary to prepare a housing supply strategy. In addition, even if North Koreans are prevented from entering, a plan is necessary to ensure structural safety since most buildings in North Korea are aging and a recent natural disaster occurs frequently. In this research, we will try to present a temporary housing supply strategy and a short-term structural reinforcement plan based on analysis of the standard housing conditions in North Korea. In this research, we represent the analysis result of the existing construction level, supply status and structural performance of North Korea. When we consider the reinforcement period and social costs, a short-term reinforcement plan is recommended rather than the full reinforcement of the aged housing in North Korea. Furthermore, we examine the ways to secure the residential safety of North Koreans through a case study of domestic and overseas temporary residential facilities, until the permanent residential facilities were supplied. According to the analysis, the tent houses were used as a form of relief housing in overseas frequently. However, the tent house is difficult to apply for domestic country with clear seasons due to insulation and heating problems. Therefore, it is appropriate to develop a residential supply strategy as focusing on the temporary housing facilities in assembled or container from, in preparation for the future population inflow.

Purpose: Soft tissue defect of the hand, which cannot be covered with skin graft or local flap, is usually reconstructed using a free flap. Temporoparietal fascial free flap is one of the best alternatives for functional reconstruction of the hand with exposed tendons, bones, and joints. Materials and Methods: We have experienced four cases of reconstruction using a temporoparietal fascial flap with a skin graft and followed up for 20 years. We conducted a retrospective review of the patients' clinical charts and photos. Results: At the time of initial injury, the average age of patients was 50.3 (39~62) years. The radial artery was used for reconstruction of the dorsal side of the hand, whereas the ulnar artery was used for that of the volar side of the wrist. Short term complication such as skin graft loss and donor site alopecia occurred. However, during the long term follow-up period, no change of flap volume was noted, and full range of motion in the adjacent joint was maintained. In addition, hyperpigmentation of the grafted skin on the flap disappeared gradually. Conclusion: Selection of the optimal flap is important for reconstruction of the hand without functional limitation. We obtained satisfactory soft tissue coverage and functional outcomes using a temporoparietal fascial free flap and followed up for 20 years.

The mapping of dark matter clustering from real to redshift spaces introduces the anisotropic property to the measured density power spectrum in redshift space, known as the Redshift Space Distortion (hereafter RSD) effect. The mapping formula is intrinsically non-linear, which is complicated by the higher order polynomials due to the indefinite cross correlations between the density and velocity fields, and the Finger-of-God (hereafter FoG) effect due to the randomness of the peculiar velocity field. Furthermore, the rigorous test of this mapping formula is contaminated by the unknown non-linearity of the density and velocity fields, including their auto- and cross-correlations, for calculating which our theoretical calculation breaks down beyond some scales. Whilst the full higher order polynomials remains unknown, the other systematics can be controlled consistently within the same order truncation in the expansion of the mapping formula, as shown in this paper. The systematic due to the unknown non-linear density and velocity fields is removed by separately measuring all terms in the expansion using simulations. The uncertainty caused by the velocity randomness is controlled by splitting the FoG term into two pieces, 1) the non-local FoG term being independent of the separation vector between two different points, and 2) the local FoG term appearing as an indefinite polynomials which is expanded in the same order as all other perturbative polynomials. Using 100 realizations of simulations, we find that the best fitted non-local FoG function is Gaussian, with only one scale-independent free parameter, and that our new mapping formulation accurately reproduces the observed power spectrum in redshift space at the smallest scales by far, up to k ~ 0.3 h/Mpc, considering the resolution of future experiments.
