Purpose: Numerous studies have shown that crestal bone resorption around the implant was related to the location of the implant abutment junction(IAJ). Recently it was hypothesized that platform switching termed the inward horizontal repositioning of the IAJ might limit bone resorption around the implants. The purpose of this clinical study was to evaluate the effect of platform switching on crestal bone resorption. Materials and Methods: The crestal bone loss of 65 external hex implants in 26 patients were radiographically measured at crown placement and follow-up examinations. 23 standard implants(non-platform switching group, NP) were connected with the matching abutments and 42 wide implants(platform switching group, PS) were connected with the 1 mm smaller diameter abutments. Results: There was significant difference of crestal bone loss between NP group and PS group. For implants in the NP group, mean crestal bone loss was $1.18{\pm}0.68\;mm$ at crown placement and $1.42{\pm}0.41\;mm$ at follow-up. The meal bone loss in PS group was $0.47{\pm}0.52\;mm$ at crown placement and $0.60{\pm}0.65\;mm$ at follow-up. When the crestal bone changes according to placement depths of implants were compared, subcrestal position of IAJ had a significantly less bone loss in PS group, but it was not in NP group. Conclusion: Within the limits of the present study, it was concluded that platform switching technique might decrease crestal bone loss around the implants. Additionally, when the IAJ of implant was placed 1 mm deeper in the alveolar bone, the effect of platform switching on bone loss was enhanced.

For the application of photo-detector as active layer, we have studied how to deposit SiGe thin film using an independent Si target and Ge target, respectively. Both targets were synthesized by purity of 99.999%. Plasma generators were generated by radio frequency (rf, 13.56 MHz) and direct current (dc) power. When Ge and Si targets were sputtered by dc and rf power, respectively, we could observe the growth of highly crystalline Ge thin film at the temperature of $400^{\circ}C$ from the result of raman spectroscopy and X-ray diffraction method. However, SiGe thin film did not deposit above method. Inversely, we changed target position like that Ge and Si targets were sputtered by rf and dc power, respectively. Although Ge crystalline growth without Si target sputtering deteriorated considerably, the growth of SiGe thin film was observed with increase of Si dc power. SiGe thin film was evaluated as microcrystalline phase which included (111) and (220) plane by X-ray diffraction method.

이 논문에서는 홍도와 마라도에서의 파랑의 통계적 특성을 살펴보았다. 두 지역에서의 스펙트럼법과 시계열에서 얻은 유의파고를 이용하여 파고주기결합분포를 얻었으며 여러 가지 통계적인 특성을 살펴보았다. 주파수의 대역폭이 협대역이 아닌 경우에 개별 파고분포에 롱기히긴스가 제안한 수정레일리분포를 사용할 수 있다. 그러나 이 분포함수는 경험상수를 결정해야하는 불편함 때문에 널리 사용되지 않고 있었다. 본 논문에서는 수정레일리분포의 경험상수를 결정하는 간단한 방법을 제안하였다. 설계파고의 추정에서 서로 다른 분포함수 선택에 따른 영향은 크지 않다. 그러나 스펙트럼법과 시계열에서 얻은 파랑자료 사용에 따라서 한계파고의 추정치는 큰 차이를 보인다. In this paper the statistical characteristics of the waves at Hong-do and Mara-do are examined. The wane scatter diagrams of H/sub s/ and T/sub z/ and H/sub 1/3/and T/sub 1/3/ at two locations are given and various statistical characteristics of the ocean waves are examined. If the sea is not narrowband, the modified Rayleigh distribution introduced by Longuet-Higgins can be used for the individual wave height distribution. However the modified Rayleigh distribution has not been widely used due to the inconvenience of determining the empirical constant. In this paper a simple method to determine the empirical constant for the modified Rayleigh distribution is proposed. Extreme waves based on the measured wave data are estimated. There is no significant difference depending on the distribution functions. However the estimations of the extreme waves from H/sub s/ and H/sub 1/3/ show considerable difference.

한국 영화 극적 구조 분석 및 새로운 지점에 대한 고찰

김도영(Kim Do Young) 한국영화학회 2008 영화연구 Vol.0 No.38

Syd Field understood the unique storylines and time ratios of mass commercial movie scenarios, and presented a form of dramatic structure which he called Paradigm. He assessed that favorable scenarios tally to such Paradigm. Of course, such argwnent is extreme, but the mention of the three chapters structure, which can be traced back to Aristotle's "Poetics", and arguments regarding the specific concept of Plot Point and elements of Paradigm, such as Mid-Point and Pinch, and their time placements are significant in movie scenarios. In reality, most mass commercial movies are known to follow such form of dramatic structure, and this is thought to be a universal storyline which existed even before Syd Field devised the Paradigm. Also, it is presumed that such Paradigm can be used in analyzing the dramatic structure of most Korean movies. The purpose of this study is to examine through actual examples whether the Syd Field Paradigm is applicable to the dramatic structure of Korean movies, to see if there are any points to revise or add to the dramatic structure of Korean movies based on the Paradigm, to investigate if the Paradigm is applicable to movies that were screened outside of the US before Syd Field presented the Paradigm, and to provide insight to other related questions. Precedent for such study can be found from Aristotle to Tolstoy. To examine whether the Syd Field Paradigm is able to provide basic principles and be a model for Korean movie scenarios, and also to investigate through specific examples the possibility of the Paradigm becoming the general storyline of movies is natural for a scholar. Hence, specific examples, such as the Korean movies Oldboy, You're My Sunshine!, and The Golden Age Of Young-Ja, and the Italian Movie Ladri Di Biciclette, have been thoroughly analyzed. As a result of this study, the following insights were discovered; first, the dramatic structure of Korean movies can be analyzed by the Syd Field Paradigm; second, based on the Syd Field Paradigm, there are possibly three supporting points that commonly exist in Korean movies; and third, the Paradigm is applicable to Italian and Korean movies that were screened before Syd Field devised the Paradigm. Such results of this study provide implications to not only scholars in universities, but also to people working in fields related to film production. After the decrease of screen-quota, reduction in production costs is one of the most significant problems faced by the Korean movie industry. The results can be important reference materials in not only the pre-production stage, but also in managing the filming schedule and cost distribution in the production stage. This is also true for the post-production stage. In addition, the results are considered to be important in the study of storylines, which is traditionally based around theories.

Most of Danis-Weber type B fracture has an oblique fracture plane proximal posteriorly to distal anteriorly. In these cases, the lateral plate has become widely accepted. However some limitation to the use of the lateral plate exist. The plate must be bent accurately and the screws in the distal fragment must be unicortical to avoid penetration into the joint, predisposing it to poor fixation in the osteoporotic bone. In 1982, Brunner and Weber introduced the antiglide plate for fixation of the shaft oblique fracture of the distal fibula, but it has not widely used. The author reviewed 21 cases treated by antiglide plate fixation from March, 1995 to March, 1999 which could be follow-up more than 1 year. We analysed the result radiographically and clinically using Ankle-Hindfoot scale(100 % total) of the American Orthopedic Foot and Ankle Society. The results obrained were as follows: 1. All fracture were united at average 8 weeks clinically and radiographically. 2. According to the Ankle- Hindfoot scale, 8 cases were above 90 points, 11 cases were beet ween 80 and 89 points and two cases were below 80 points. 3. One case had an injury to intermediate dorsal cutaneous nerve.

In construction sites, policies are changing considering the convergence of 3D scanning and BIM. In order to respond to this, it is urgent to develop guidelines for systematic collaboration methods that take into account the perspectives of practitioners. By participating in the delivery process using 3D scanning technology, tasks such as ordering, field scanning are defined in terms of mutual communications. Also, the collaboration process is about communications between off-site and on-site, such as feed-back using data and documents. In the future, we will propose guidelines based on such collaborative process models.

The kinetic facade system is an interactive building envelope which is adaptive to environmental condition by transforming the behaviour of its components. The design process of kinetic facade system calls for a novel approach. It needs to support designers to adopt technologies from multidisciplinary fields such as physical computing and robotics. In this paper, prototyping method is introduced as a useful technique for implementing kinetic facade systems. In order to incorporate prototyping method into architectural design process, two aspects are investigated in digital design studio: (1) The interactions between digital and analogue environments (2) The role of traditional design tools. Furthermore, the role of BIM is investigated by analyzing two aspects.

반월상 연골판의 뿌리파열의 심각성이 인식되면서 이에 대한 적극적인 봉합이 필요하게 되었다. 특히 후각부 뿌리 파열에 대한 봉합 방법과 결과가 최근에 많이 보고되고 있다. 그러나 전각부 뿌리 파열에 대한보고는 아직 보고된 바 없으며 이에 저자들은 과거에 시행했던 원판형 연골의 부분 절제 후 발생한 의인성 뿌리 파열과 이로 인한 아탈구를 경험하였고 이를 봉합나사를 이용하여 정복하여 좋은 결과를 얻었기에 보고하는 바이다. As awareness of root tear of meniscus have been increased, it became necessary to have an intensive repair. Posterior horn tear, especially for a lot of repair methods and the results have been reported recently. The report of the anterior root tear has yet to be found. We recently encountered a patient with an iatrogenic meniscal subluxation caused by past experienced partial menisectomy for discoid meniscus. Thus, we repots the technique and clinical results of arthroscopic repair of subluxated lateral meniscus anterior root tear using suture anchor.

Purpose: The purpose of this study was to evaluate the clinical and radiologic outcome of syndesmosis fixation using TightRope$^{TM}$ (Arthrex, Naples, FL, USA) in acute syndesmosis injuries. Materials and Methods: Twenty-five consecutive patients with acute syndesmosis injuries, treated using TightRope$^{TM}$, were reviewed. Patients were evaluated preoperatively and at the last follow-up (at least 12 months postoperatively). Clinical outcomes were assessed using American Orthopaedics Foot and Ankle Society (AOFAS) ankle-hindfoot score and self-subjective satisfaction survey. Three radiologic parameters were evaluated two times at the preoperative and final follow up from the nonweightbearing ankle anteroposterior radiographs. Results: The mean AOFAS ankle-hindfoot score was 95.5 at the final follow-up. According to the satisfaction survey, 21 patients chose excellent, and four patients chose good. All radiologic parameters, including the mean tibiofibular clear space, mean tibiofibular overlap, and mean medial clear space on nonweightbearing ankle anteroposterior view, significantly improved after surgery. Complications occurred in only one patient who experienced knot irritation with infection. Conclusion: The short-term surgical results of syndesmosis fixation using TightRope$^{TM}$ were good to excellent, both clinically and radiographically. These results suggest that the fixation using TightRope$^{TM}$ is a valid option for acute syndesmosis injury.
