The purpose of this study was to investigate the effect of democratic and autocratic behavior type of dance art instructors in elementary dance education on class satisfaction focused on mediations of flow and perceived competence. A total of 500 questionnaires were distributed but insincerely replied or double-replied questionnaires were excluded and finally 453 questionnaires were analyzed for this study. For the analysis of the data, SPSS 18.0 version was used and double mediation model operating in serial, proposed by Hayes and a bootstrapping method were used. First, instructor's democratic behavior type was statistically positive effect on class satisfaction. However autocratic behavior type was statistically negative effect. Second, the indirect effect of instructor's democratic type and autocratic behavior type on class satisfaction through the flow were statistically positive significant. Third, the indirect effect of instructor's democratic behavior type on class satisfaction through the perceived competence was statistically significant. However autocratic behavior type was statistically negative effect. Lastly, the indirect effect of instructor's democratic and autocratic behavior types on class satisfaction through the flow and perceived competence were statistically positive significant.

The research focuses on the provincial universities in the western region of China and investigates the research level of 12 provincial universities from 2017 to 2021, considering both static efficiency and dynamic efficiency. The static efficiency is examined using Data Envelopment Analysis (DEA), while the dynamic efficiency is analyzed using the Malmquist model. The analysis results are as follows: the scientific research efficiency of universities in the 12 western provinces is generally not high. Against the background of the "Double First-Class" construction, the overall efficiency of scientific research in universities is showing an increasing trend. The main reason for the increase in scientific research efficiency is the increase in scale efficiency in recent years. The total factor productivity (TFP) of research activities is influenced by the technology progress index and exhibits a pattern of initial increase, followed by a decline, and then an increase again. Research conclusion: Western colleges and universities should reasonably allocate resources for scientific research activities, perfect scientific research mechanisms, improve management standards, promote scientific innovation and corresponding achievements, and ultimately raise the scientific and technological level in western China.

The purpose of this study was to explore the determinants of minor and double major satisfaction of university students. To achieve this, F.G.I. was performed with the university teaching assistants to create a questionnaire. The survey was performed to the subject of 239 university students completing minor and double major. A statistical program (SPSS) was used for data analysis and factor analysis, reliability analysis, and multiple regression analysis were conducted. First, it drew three principal factors including need-achievement, class discrimination, and course registration discrimination by conducting factor analysis regarding survey questions on minor and double major. Next, the multiple regression analysis identifying the effects of the three principal factors was conducted. The results indicated three principal factors to be statistically significant. The degree of influence over satisfaction marked the highest in the order of need-achievement, class discrimination, and course registration discrimination. In the conclusion, the positive function and possibilities of minor and double major are proposed.

Mitral and aortic valve replacement with tricuspid annuloplasty was undertaken in 5 patients out of 38 valvular surgery between the period from Jan. 1977 to May 1979 in the Dept. of Thoracic and Cardiovascular Surgery in Korea University Hospital. All were male patients with age ranging from 18 to 42 years, and preoperative evaluation revealed one case in Class IV, and four cases in Class III according to the classification of NYHA. Preoperative diagnosis was confirmed by routine cardiac study including retrograde aorto- and left ventriculography, and there were two cases with MSi+ASi+Ti, two cases with MSi+Ai+Ti, and one case with Mi+Ai+Ti. Double valve replacement was performed under the hypothermic cardiopulmonary bypass with total pump time of 247 min. in average ranging from 206 min. to 268 min. During aortic valve replacement, left coronary perfusion was done in the first two cases, and cardiac arrest with cardioplegic solution proposed by Bretschneider was applied in the remained three cases. Starr-Edwards, Bjork-Shiley prosthetic valves and Carpentier-Edwards tissue valve were replaced in the aortic area, and Carpentier-Edwards and Angell-Shiley tissue valves were replaced in the mitral area with each individual combination [three prosthetic and two tissue valves in the aortic, and five tissue valves in the mitral area respectively]. Postoperative recovery was uneventful in all cases except one case with hemopericardium, which was managed with pericardiectomy on the postoperative 10th day in good result. Follow-up after double valve replacement of the all five cases for the period from 6 months to 33 months revealed satisfactory adaptation in social activity and occupation with cardiac function of Class I according to the classification of NYHA In all five cases.

One of the most interesting classes of algebraic codes is the class of quadratic residue (QR) codes over a finite field. A natural construction doubling the lengths of QR codes seems to be the double circulant constructions based on quadratic residues given by Karlin, Pless, Gaborit, et. al. In this paper we define a class of triple circulant linear codes based on quadratic residues. We construct many new optimal codes or codes with the highest known parameters using this construction. In particular, we find the first example of a ternary [58, 20, 20] code, which improves the previously known highest minimum distance of any ternary [58, 20] codes.

A three-level decoupled sliding mode controller is developed to achieve asymptotic stability for a class of sixth-order nonlinear systems. The sixth-order system is decoupled into three subsystems according to the structure of the whole system. Each subsystem has a separate control target in the form of a sliding surface. The information of the third sliding surface is transferred to the second one through an intermediate variable and the information of the second sliding surface is transferred to the first one through another intermediate variable. Consequently, the controller designed on the basis of the first sliding surface can make three subsystems move toward their sliding surfaces, respectively. The three-level decoupled sliding mode controller is applied to the double-inverted pendulum problem where the zero stable states are required.

In the present study, a combined ratio cum regression estimator is proposed to estimate the population mean of the study variable in the presence of a non-response using an auxiliary variable under double sampling. The expressions of bias and mean squared error(MSE) based on the proposed estimator is derived under double (or two stage) sampling to the first degree of approximation. Some estimators are also derived from the proposed class by allocating the suitable values of constants used. A comparison of the proposed estimator with the usual unbiased estimator and other derived estimators is carried out. An empirical study is carried out to demonstrate the performance of the suggested estimator and of others; it is endow that the empirical results backing the theoretical study.

Facial esthetics and smiling are key components in nonverbal communication and have an important role in determination of the first impression of a person. The various components of the smile in dental esthetics include Gingival scaffold, lip framework, and Teeth. The periodontist creates a smile by performing various periodontal plastic microsurgery procedures for management of mucogingival problems. A 25-year-old patient reported to the Department of Periodontology at Teerthanker Mahaveer Dental College and Research Center, Moradabad, Northern India, with the chief complaint of long looking teeth in the upper jaw, making him conscious while smiling. Miller class I gingival recession with Maxillary left canine (23) was diagnosed. Periodontal plastic microsurgery employing double papilla grafting with connective tissue graft harvested from the palate in order to cover denuded root was performed using microsurgical instruments and microsuturing with 6-0 suturing material under magnification. Healing was uneventful, with achievement of 100% root coverage of denuded root after three months. The patient was highly impressed and satisfied with his enhanced smile.
