The Status Quo and Problems of Red Cultural Sites in the New Era and Their Exploration Paths: Taking the Luxi Region as an Example

Red cultural site is the carrier of red culture,containing profound revolutionary history and value of the times,we should deeply excavate the intrinsic potential of red cultural sites,pay attention to the ontological protection of red cultural sites,develop and improve the red cultural innovation projects,and strengthen the red culture itself and supporting the construction.This paper takes the old revolutionary area of Luxi as an example,conducts field investigation and visits based on the local county records and party history materials,and investigates a total of five red cultural sites and memorial halls in Luxi,focusing on the actual achievements and problems exposed in the protection and development of the current red cultural sites,to provide references and thinking for the protection,development,and innovative utilization of red cultural sites in the new era of our country.

SOME PROBLEMS CONCERNING THE CURRENT S&T POLICY-MAKING

Ⅰ. RELEVANT CONCEPTS TO BE CLARIFIED When we talk about S&T policies, there are two concepts involved in the policy-making: one is S&T expenditure and the other is R&D input. The implications of the two are quite different. The former refers to all funds spent on S&T activities and the latter means the total expense used for a given project of systematic innovation. According

Enlightenment of Successful Experience of Rural Tourism in South Korea to Rural Tourism in Tai'an City

To revitalize rural tourism and improve the quality of life of rural residents,the successful experience of rural tourism in South Korea is used for reference,with an important significance for promoting the development of rural tourism in Tai'an City.In this paper,three successful rural tourism cases of South Korea(Shuchuan,Hannong Village,Xinli Mupianwa Village)are analyzed first,and their successful experience is summarized.On the basis of accurately grasping current situation and problems of rural tourism development in Tai'an City,the countermeasures of promoting the development of rural tourism in Tai'an City are proposed:mobilizing the enthusiasm of villagers,multi-channel access to funds,diversified talent cultivation methods,product marketing system,and rural tourism management system.

A new alternating positive semidefinite splitting preconditioner for saddle point problems from time-harmonic eddy current models

Based on the special positive semidefinite splittings of the saddle point matrix, we propose a new Mternating positive semidefinite splitting （APSS） iteration method for the saddle point problem arising from the finite element discretization of the hybrid formulation of the time-harmonic eddy current problem. We prove that the new APSS iteration method is unconditionally convergent for both cases of the simple topology and the general topology. The new APSS matrix can be used as a preconditioner to accelerate the convergence rate of Krylov subspace methods. Numerical results show that the new APSS preconditioner is superior to the existing preconditioners.

Aripiprazole and Cariprazine for Bipolar Disorder?

In this article, the present author, a research psychologist and measurement expert, evaluates the major clinical trials used to support the use of aripiprazole and the chemically almost identical cariprazine for treating bipolar disorder. The main problem with the trials is that they were conducted mainly with outpatients, who on average were only moderately manic in the mania studies and only moderately depressed in the depression studies. The effectiveness of aripiprazole and cariprazine in treating moderate mania, most likely hypomania, and moderate depression, was far from encouraging. Aripiprazole produced just 7% greater reduction of mania symptoms than did placebo treatment, and just 1% greater reduction of depression symptoms than did placebo treatment when administered, as is common practice, with an SSRI or SNRI antidepressant. Cariprazine proved to be not much better because at the high dosage level of 3.0 mg/day to 12.0 mg/day, cariprazine produced only 9% greater reduction of mania symptoms than did placebo treatment, and at the typical low dosage of 1.5 to 3.0 mg/day produced just 4% greater reduction of depression symptoms than did placebo treatment. Moreover, as the pharmaceutical industry has long suspected, there is a massive placebo effect associated with these two drugs, especially for depression. These findings imply that government regulatory authorities’ approval of aripiprazole and cariprazine as mood stabilizers for treating bipolar disorder is dubious. Nevertheless, the possibility remains that the purported mood-stabilizing mechanism of these two medicines is activated only with patients presently experiencing severe mania or severe depression, a possibility that requires an in-hospital clinical trial or, at the very least, a longitudinal analysis of bipolar patients’ treatment records. Furthermore, an appendix to the present article demonstrates that the measures used in the trials, the Young Mania Rating Scale and the Montgomery-Asberg Depression Rating Scale, are deficient and that a briefer combination measure focusing only on the core symptoms of bipolar disorder should be used.

A novel hybrid FEM-BEM method for 3D eddy current field calculation using current density J

This paper introduces a novel hybrid FEM-BEM method for calculating 3D eddy cur-rent field. In the eddy current region, the eddy current density J is solved by the finite element method (FEM) which is discretized by brick finite element mesh, while in the eddy current free re-gion, the magnetic field intensity H is solved by the boundary element method (BEM) which is dis-cretized by rectangular boundary element mesh. Under the boundary conditions, an algebraic equation group is obtained that only includes J by eliminating H. This method has many advan-tages over traditional ones, such as fewer variables, more convenient coupling between the FEM and the BEM and wider application to multiply-connected regions. The calculated values of two models are in good agreement with experimental results. This shows the validity of our method.

ERROR ESTIMATES FOR THE TIME DISCRETIZATION FOR NONLINEAR MAXWELL'S EQUATIONS

This paper is devoted to the study of a nonlinear evolution eddy current model of the type δtB（H） ＋ △↓× （ △↓ × H） =0 subject to homogeneous Dirichlet boundary conditions H × v = 0 and a given initial datum. Here, the magnetic properties of a soft ferromagnet are linked by a nonlinear material law described by B（H）. We apply the backward Euler method for the time discretization and we derive the error estimates in suitable function spaces. The results depend on the nonlinearity of B（H）.
