Kobayashi discussed some kinds of standard embeddings into 3-manifolds of spatial graphs.He introduced the concept of book presentation,which is a standard embedding of spatial graphs with good properties,and proved that the book presentation of minimum sheets of K n is unique up to the sheet translation and the ambient isotopy.In this present paper we give the definition of skeleton presentation of spatial graphs,and prove that the skeleton presentation of minimum floors of a complete bipartite graph K m,n is unique up to ambient isotopy.

Dear Editor,Urinary incontinence(UI)is defined as involuntary leakage of urine.[1]Higa and Lopes.[2]found that nursing activities that require greater physical effort increase urinary loss among female nurses with UI,resulting in stress,humiliation,and lack of focus at work.Pelvic floor muscle exercises(PFME)should be used as a health promotion strategy for the prevention and management of UI among female nurses,especially in the time of COVID‑19 pandemic as nurses are faced with numerous tasks and stress.The use of sanitary pad is the most frequent strategy used by female nurses to manage UI during working hours,and this approach is not usually convenient for them.[2]UI affects the quality of life and sexual health of female nurses.[3]The risk factors for UI among females are aging,childbearing,increase in body mass index,anxiety,depression,and musculoskeletal disorders.

Based on the principles of rock mass mechanics, the author analyzed in detail several main influence factors resulting of water gush in Zibo coal field. A basic law is presented in this paper.In large quantity of water gush facts prove that the ends of microcracks within coal bed floor are the major locations concentrating stress, and consequently the weak points leading to water gush.This should be carefully taken account when a critical hydraulic pressure equation is constructed.The Griffith’s intensity condilion presupposing microcrocks exist is media, therefore,is applied to the determination of the critical hydraulic pres.pressure equation of the extremely easy rupture points within the floor of mining area in Zibo coal field.There is equation as follows:

OBJECTIVES The objective was to establish a combination of factors(self-report and physical)predictive of PFMD in women with lumbopelvic pain.METHODS Participants completed a battery of self-report and physical assessments(masked assessors).Three clinical findings characterized PFMD:weakness of the pelvic floor,lack of coordination of the pelvic floor,and pelvic floor muscle tenderness on palpation(bilateral obturator internus).

OBJECTIVE In women who undergo provider-guided vaginal biofeedback of pelvic floor muscle strength, we sought to determine whether the level of the provider correlates with the patient′s ability to achieve adequate pelvic floor muscle contractions (PFMCs). METHODS From August 2017 to April 2018, patients from 2 urogynecology clinics were recruited to participate in an institutional review board-approved, prospective study examining PFMCs. Pelvic examination and teaching session were done by providers who had specific training on how to assess pelvic floor muscle strength using the validated, modified Oxford scale. Patients were asked to perform a baseline PFMC during a 2-digit pelvic examination. Thereafter, patients were counseled to relax their muscles, identify the levator ani muscles during provider teaching, and perform 3 consecutive provider-guided PFMCs. The strength of each PFMC was measured, and the time-to-teach (TTT) was recorded. The level of provider and TTT were correlated with PFMC1 to PFMC3 using Spearman correlation coefficient.

INTRODUCTION Verbal instructions are used clinically to encourage activation of the pelvic floor muscles (PFM). Whether separate layers of PFM activate differently in response to instructions remains unknown. AIM To test the hypotheses that (i) instructions that aimed to bias activity of a specific muscle layer would increase activation of the targeted layer to a greater extent than the other layer,(ii) activity of individual PFM layers would differ between instructions, and (iii) PFM activity would be symmetrical for all instructions.
