Objective : This study aimed to conduct a bibliometric analysis on pelvic parameter related research over the last 30 years, analyzing trends, hotspots, and influential works within this field. Methods : A comprehensive Web of Science database search was performed. The search yielded 3249 results, focusing on articles and reviews published from 1992 to 2022 in English. Data was analyzed using CiteSpace and VOSviewer for keyword, authorship, and citation burst analysis, co-citation analysis, and clustering. Results : The number of publications and citations related to pelvic parameters has increased exponentially over the last 30 years. The USA leads in publication count with 1003 articles. Top publishing journals include the European Spine Journal, Spine, and Journal of Neurosurgery: Spine, with significant contributions by Schwab, Lafage V, and Protoptaltis. The most influential articles were identified using centrality and sigma values, indicating their role as key articles within the field. Research hotspots included spinal deformity, total hip arthroplasty, and sagittal alignment. Conclusion : Interest in pelvic parameter related research has grown significantly over the last three decades, indicating its relevance in modern orthopedics. The most influential works within this field have contributed to our understanding of spinal deformity, pelvic incidence, and their relation to total hip arthroplasty.

Effect of protonation and deprotonation of ionization compounds is an important application in Comparative molecular field analysis (CoMFA). There are enough information's were reported about different CoMFA applications such as Series design and selection of training set, Geometries and optimizations of molecules, Effect of partial atomic charges, bioactive conformations and alignment, Interaction energy fields, Effects of different grid spacing etc. However limited information's are available about the ionization of compounds. This study aimed at the critical review of about the effects of protonation of ionizable molecules and its impact on the predictability of CoMFA models. We also discussed about previous implications and the things needed to be considered to come for a final conclusion about its impact on CoMFA predictability.

본 연구는 초기 치매환자를 대상으로 전산화 인지재활프로그램이 전두엽 집행기능 중 생성 이름대기에 미치는 효과를 파악하고, 치매 환자의 조기 언어중재에 관한 기초자료를 제공하였다. 분석 대상은 경증치매환자 29명으로서 전산화 인지재활프로그램(CoTras)을 중재하는 실험군 21명과 지필과 테이블활동 등 전통적인 면대면 언어재활을 중재하는 대조군 8명으로 분류되었다. 실험집단과 대조집단은 모두 12주 동안 순차적 언어 회상 기억훈련, 연합회상 기억훈련, 언어 범주화 기억훈련, 언어통합 기억훈련을 진행하였다. 의미유창성과 음소유창성의 사전검사점수를 공변량으로 통제한 Welch's robust ANCOVA분석 결과, 실험집단과 대조집단은 의미유창성과 MMSE-K의 변화에서 유의미한 차이가 있었다(p<0.05). 반면에, 음소유창성은 실험군과 대조군 모두 기초선단계에 비해서 12주간의 치료 후 유의미하게 증가하였지만 통계적으로 치료방법에 따른 유의미한 차이는 없었다. 본 연구의 결과는 전산화 인지재활프로그램이 전통적인 인지재활에 비해서 의미유창성의 향상에 효과적일 가능성을 시사한다.

본고는 국가무형문화재 제3호이며 유네스코 세계무형문화유산인 남사당놀이 덧뵈기의 연기 훈련 활용 방향에 관해 탐구해 보았다. 남사당놀이의 단일 연희 종목이 아닌 여섯 연희 종목 모두가 등재된 것으로 보아 민간을 떠돌며 연희를 담당했던 역사적·전통적 가치를 이해할 수 있다. 덧뵈기가 가지는 재담의 즉흥성, 덧뵈기춤을 통한 간결한 한국적 움직임과 호흡, 악사와의 재담을 통한 공간 자각 능력, 보편적 한국 정서는 현대 연기 훈련법으로 충분히 활용 가치가 있다. 상대방의 대사를 잘 듣고 앞의 대사를 예상하지 않는 훈련, 즉 매순간의 집중력에 도움이 된다. 배우 자신의 몸에 대한 자각과 통제 그리고 상대 배우와 전체 공간의 인식 또한 전통극과 현대극 모두에게 도움이 되는 것이다. 현대적 연기 훈련 방법이면서 저절로 한국적 정서를 통한 내재적 충동도 얻게 된다.

The undrained shear strength of soil is considered one of the engineering parameters of utmost significance in geotechnical design methods. In-situ experiments like cone penetration tests (CPT) have been used in the last several years to estimate the undrained shear strength depending on the characteristics of the soil. Nevertheless, the majority of these techniques rely on correlation presumptions, which may lead to uneven accuracy. This research's general aim is to extend a new united soft computing model, which is a combination of random forest (RF) with grasshopper optimization algorithm (GOA) to the pile set-up parameters' better approximation from CPT, based on two different types of data as inputs. Data type 1 contains pile parameters, and data type 2 consists of soil properties. The contribution of this article is that hybrid GOA - RF for the first time, was suggested to forecast the pile set-up parameter from CPT. In order to do this, CPT data and related bore log data were gathered from 70 various locations across Louisiana. With an R² greater than 0.9098, which denotes the permissible relationship between measured and anticipated values, the results demonstrated that both models perform well in forecasting the set-up parameter. It is comprehensible that, in the training and testing step, the model with data type 2 has finer capability than the model using data type 1, with R² and RMSE are 0.9272 and 0.0305 for the training step and 0.9182 and 0.0415 for the testing step. All in all, the models' results depict that the A parameter could be forecasted with adequate precision from the CPT data with the usage of hybrid GOA - RF models. However, the RF model with soil features as input parameters results in a finer commentary of pile set-up parameters.

Background: Purpose of this study is mat exercises and sling exercises that based on proceeding studies for exercising protocol for spinal stabilization. Methods: We analyze many other bibliographies and result of studies. Results: The vertebrae stabilization practices are formed on intra-abdominal pressure and converted into isolation of our body and limbs gradually through co-contraction training of transverse abdominis, pelvic floor muscle and diaphragm. Also, for prevention of low back pain and relapse, it is diverted to reflex muscle contraction training as well as functional integration. What is better, it should carry out with Activity of Daily Living. Conclusion: We should feel the necessity of it, more effective recognition training of local muscle for chronic low back pain patients. Besides, it is suggested that we should import measurable equipment and go hands with discipline.

In this paper we develop textbook 'Modem Algebra' for training mathematics teacher of secondary schools. In order to understand mathematics teacher's viewpoint about desirable textbook 'Modem Algebra' we created a Questionnaire related with curriculum and textbook for training mathematics teacher of secondary schools. We analyze the result of the questionnaire along with recent studies on teacher education and come up with basic principles of developing textbook 'Modern Algebra'. The first version of 'Modern Algebra for Mathematics Teachers' that we have developed based on our study can be found in website 'www.teacheredu.co.kr'.

A key issue toward mobile multimedia communications is to create technologies for broadband signal transmission that can support high quality services. Such a broadband mobile communications system should be able to overcome severe distortion caused by timevarying multi-path fading channel, while providing high spectral efficiency and low power consumption. For these reasons, an adaptive suboptimum decision feedback equalizer (DFE) for the single-carrier shortburst transmissions system is considered as one of the feasible solutions. For the performance improvement of the system with the short-burst format including the short training sequence, in this paper, the multiple-training least mean square (MTLMS) based DFE scheme with soft decision feedback is proposed and its performance is investigated in mobile wireless channels throughout computer simulation.
