본 논문에서는 실시간 시스템에서의 상호배제를 제한된 시간안에 해결하기 위한 방안을 제안한다. Sanders 알고리즘을 이용해서 임계영역을 사용하기 위해 필요한 메시지의 수가 노드마다 서로 다를 수 있는 점을 이용한다. 즉, 서로 다른 데드라인을 가진 노드들이 임계 영역을 효과적으로 사용하기 위해서 데드라인이 상대적으로 가까운 노드가 임계영역 사용을 위해서 전송하는 메시지의 수를 적게 갖는 구조를 취함으로 전체적인 데드라인 miss 횟수를 줄이게 된다. 시뮬레이션을 통해서 이것의 성능 향상을 보인다.

Purpose: This study evaluated the clinical and radiological results of 6.5 mm full threaded cancellous bone screw fixation of calcaneal fractures. Materials and Methods: Thirty seven patients diagnosed with Sanders type II or III calcaneal fractures, who underwent open reduction and internal fixation with a 6.5 mm full threaded cancellous bone screw between August 2014 and August 2017, were analyzed. Both the preoperative and postoperative Böhler angle and Gissane angle were measured radiographically. American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale on the final follow-up were also assessed. Results: The mean age of the patients was 52.7 years and the mean follow-up period was 29.5 months. In the Sanders classification, type II and III were 16 and 24 cases, respectively. The Böhler and Gissane angles improved from 21.2° and 122.6° preoperatively to 21.6° and 120.3°, respectively, in the postoperative radiographs. All cases achieved bony union, and the AOFAS ankle-hindfoot scale was 90.7 and 91.3 in Sanders type II and III, respectively, at the final follow-up. Conclusion: The treatment of calcaneal fractures using a 6.5 mm full threaded cancellous bone screw can reduce the complications with minimally invasive surgery and achieve firm fixation.

접미사 배열은 긴 문자열에 대해 효율적인 문자열 검색을 가능하게 하는 자료구조이다. 접미사 배열은 문자열의 접미사들의 사전식 정렬순서를 배열로 저장한다. 비슷한 효과를 가진 접미사 트리에 비해서 접미사 배열은 저장 공간을 적게 차지하기 때문에 생명정보과학의 염기 서열 등 큰 크기의 문자열의 처리에 더욱 유리하다. 본 논문에서는 2003년에 발표된 Ko-Aluru, K$\square$rkk$\square$inen-Sanders 및 기존의 Manber-Myers 등 세 개의 접미사 배열 생성 알고리즘들의 염기 서열 입력 자료에 대한 실행 시간 및 기억 장치 사용량을 실험을 통해 비교한다. 특히 Ko-Aluru와 K$\square$rkk$\square$inen-Sanders 알고리즘은 실행 시간 및 저장 공간의 이론적인 복잡도가 O(n)으로 동일하기 때문에 실험을 통해서 계산 복잡도에 숨어있는 상수를 비교한다. 실험 결과 K$\square$rkk$\square$inen-Sanders 알고리즘이 가장 효율적임을 보인다.

This paper based on Sanders theory aims to investigate the vibration of SWCNTs considering the clamped-simply supported, clamped-free, clamped-clamped and simply supported-simply supported end conditions. After developing the governing equation of the objective system, the Rayleigh-Ritz technique is implemented for the purpose of obtaining the frequency equation in the eigen form. In addition, the applicability of this model for the analysis of vibration of CNTs is examined with the effect of length and ratio of height-to-radius. A detailed description of different types of SWCNTs with different indices is provided in the theoretical methodology. The effect of extended length is stimulated with increasing the radii and the model is effective because it also predicts the effect of thickness on vibration of SWCNTs. For different boundary conditions, the present results are verified with earlier literature.

This study utilized a semantic network analysis for Korean major newspaper articles concerning 'Bernie Sanders'. 'Bernie Sanders' promotes conservative values of 'Americana' as well as the progressive values of 'relieving inequality', and thus, perhaps he is a subject on which ideological differences between the press can be distinctively manifest. Upon comparison of the priority of frequency between the conservative press and progressive press, the conservative press frequently used the expressions, 'socialist' and 'black man', whereas the progressive press frequently used the expressions, 'inequality' and 'problem'. Both the conservative press and progressive press displayed particularly different semantic compositions with the term, 'Korea'. The progressive press aimed to express the criticism of social problems and established politics identified by Sanders in relation to the 'Korean' society, whereas the conservative press criticized the blunt expressions stating that a specifically named politician resembles Sanders, and the specific party and term of 'Korea'. A completely different disposition of reports from different perspectives and context was ascertained, regardless of the use of the same terms. Thus, it is demonstrated that the semantic composition of the press on a specific issue displays significant differences according to their ideological disposition.

This study was carried out to examine the characeristics of waste sanders(S)from. plywood and pre-finishing plywood surface sanding and double saw finishing, as a new extander in urea-formaldehyde resin(UFR) in plywood adhesive, and to focus, adhesive strength using the glue extended with milled sanders(MS) as extender, leveling the optimum amount of MS to be added, and examining the physical properties of glue extended MS & S. Also economical good feasibility of substitution for wheat flour(WF) with MS as a new extender is analyzed and presented in details. Selecting three standard samples of 80, 100 and 180 mesh, sorking them in distilled water at $20^{\circ}C$, 24 hours, redrying at $105^{\circ}C$ and rescreening the sample with standard screen, again, the 3 samples of 80, 100, and 180 mesh are passed 23 percent through 80 mesh sander standard sample 27 percent through on 100 mesh and only 10.9 percent through 180 mesh, respectively. The particle size of retained parts are greater in size of redried form. It seems undoubtly that particles to be extended in glue are got swollen and become greater in size and coarser in shape. The shape of fresh S particles are irregular thin needle with small scale, as shown in Figure 5. PFS are so finer than plywood S that only 9.8 percent of the S retained on 100 mest screen, 24. 30 percent on 100-160 mesh, and 65.9% on 160-180 mesh. But particle size of the fresh S is large enough to make the viscosity of glue direct extended with S too high to apply it glue spreader. The glue extended with milled sanders(MS). 3 hours milled PFS or 6 hours milled plywood S, having particle sizes shown in Tables 7 and 8, as ratio of Reain/MS/WF/water: 100/8/8/10, indicate good viscosity of 16 to 24 ps, as shown in Figure 5, for applying direct to glue spreader, have high tensile-shear strength (adhesive strength), 102.4 kp/$cm^2$, and 94 percent wood failure.

Purpose: To assess the clinical and radiographic results and complications of arthroscopy-assisted reduction and percutaneous fixation for patients with tongue-type Sanders type II calcaneal fractures. Materials and Methods: Between August 2014 and December 2015, 10 patients who underwent surgery using subtalar arthroscopic assisted reduction and percutaneous fixation for tongue-type Sanders type II calcaneal fractures were reviewed. The mean age was 50.8 years (36~62 years), and the mean follow-up period was 24 months (12~40 months). The clinical results were evaluated using the visual analogue scale (VAS) and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score at the regular follow-ups, and the foot function index (FFI) at the last follow-up. The subtalar range of motion (ROM) was evaluated and compared with the uninjured limb at the last follow-up. The radiographic results were assessed using the Bohler's angle from the plain radiographs and the reduction of the posterior calcaneal facet using computed tomography (CT). The postoperative complications were assessed by a chart review. Results: The VAS and AOFAS ankle-hindfoot score improved until 12 months after surgery. The FFI was 15 (1.8~25.9) and subtalar ROM was 75.5% (60%~100%) compared to the uninjured limb at the last follow-up. The $B{\ddot{o}}hler^{\prime}s$ angle was increased significantly from $2^{\circ}$ ($-14^{\circ}{\sim}18^{\circ}$) preoperatively to $21.8^{\circ}$ ($20^{\circ}{\sim}28^{\circ}$) at the last follow-up. The reduction of the posterior facet was graded as excellent in five feet (50.0%) and good in five (50.0%) on CT obtained at 12 months after surgery. One foot (10.0%) had subfibular pain due to a prominent screw head. One foot (10.0%) had pain due to a longitudinal tear of the peroneal tendon that occurred during screw insertion. Conclusion: Subtalar arthroscopic-assisted reduction of the posterior calcaneal facet of the subtalar joint and percutaneous fixation is a useful surgical method for tongue-type Sanders type II calcaneal fractures.
