The dual functions of government participation and governance in the development of the existing building energy-saving renovation market determine the importance of the government’s scientific and effective actions.Continuously improving the government’s role is to promote the effective operation of the existing building energy-saving renovation market.Based on the inherent requirements of improving the government governance capacity in the development of the existing building energy-saving renovation market,this paper constructs the implementation path for the development of the existing building’s energy-saving renovation market from the three dimensions of practical concept,practical process and practical methods.From the four aspects of improving the legal and regulatory system,building a market information sharing platform,establishing a sound market supervision mechanism,and consolidating and improving the market accountability system,we will structure the existing building energysaving renovation market development to improve the government’s ability to restrain and implement measures.From the four levels of improving the market incentive mechanism,optimizing the market financing environment,clarifying the position of market resource allocation,and building a social operation platform,design measures to improve government incentives in the development of the existing building energy conservation renovation market.From the shaping of governance yuan organizational roles,governance capacity and responsibilities of departments at all levels to define boundaries,to build four main interactive platform governance perspective,the main parties demand balance the interests of both the governance capacity development planning in the government market,building energy-saving market to enhance the implementation of countermeasures.In order to promote the healthy and sustainable development of the existing building energy-saving renovation market based on the enhancement of government governance capacity. 展开更多

Men's health awareness, including the research and study of quality of life, sexual desires and risk factors, has increased worldwide. In Thailand, this advancement is made possible by cooperation, research and sponsorship from the local Thai community. This article aims to illustrate the sexual attitudes of Thai people, to determine the degree of erectile dysfunction (ED) and to investigate how to manage and cope with ED in a Thai community. We reviewed the relevant literature from Thai-based articles and surveys in regard to men's health, sexual attitudes, the prevalence of ED and common risk factors in the Thai community. The primary risk factor for ED in Thai men was age-related health decline and the presence of vascular disease. Most Thai men will seek consultation from their partner in regard to ED. The main presentation of metabolic disease in Thai patients was dyslipidemia. New selective serotonin reuptake inhibitors are not available for premature ejaculation in Thai communities. The debate in regard to malpractice compensation is an issue that should be closely monitored. There is currently a shortage of home care for the elderly in Thailand. The insights provided by the articles helped recruit the study patients and in turn, helped us gain knowledge that can be translated into improved men's health care in Thailand. 展开更多

Aim: We developed a scale to measure the social activities of community-dwelling older men requiring support. Methods: The participants were a group of 134 men, ≥65 years old, who required support and were living in Hokkaido, Japan. An anonymous questionnaire was administered through individual interviews. Valid responses were obtained from 121/134 interviewees. The construct validity of the resulting scale was assessed by exploratory factor analysis (EFA). Criterion-related validity was tested with Spearman’s rank correlation test based on the Social Activities Index for Elderly People (SAI-E). Reliability was assessed by Cronbach’s alpha. Results: A Social Activities Scale for Community-dwelling Older Men Requiring Support (SASOMS) scale was created, comprised of the following three subscales: daily interactions with familiar people;intimate relationships with family members;and interactions with others through activity programs (e.g., exercise, games, recreation, etc.). The created SASOMS scale correlated with the SAI-E (r = 0.557), and its criterion-related validity was confirmed. The alpha coefficient of the new scale was 0.791, and its internal consistency was confirmed. Conclusions: The reliability and validity of the developed SASOMS scale was confirmed, demonstrating that it can be used to assess social activities specifically in older men requiring support. Our results suggest that the scale can be used effectively by care providers who support older men requiring care. The usability of the SASOMS should continue to be improved, and it is necessary to verify its validity in longitudinal studies. 展开更多

Sleeve pattern design of men’ s tailored - suit is one of the most difficult problems of clothing pattern design. Based on the experimental studies of armhole girth, the difference of armhole width and crown height, crown angle, under sleeve curve’s diagonal line length, crown ease and its distribution rule, this paper mainly deals with the sleeve pattern design of tailored - suit for Chinese men. The influences of these factors are discussed and furthermore, some qualitative, quantifiable conclusions are drawn to design perfect pattern of men’ s tailored - suit sleeve. 展开更多

The purpose of this essay is to study whether the linguistic behaviour of adult women using hedging and tags as indicative of an intrinsically tentative gender identity or of the effects of male dominant position through analyzing daily conversations of the heterosexual couples.The small scale study employs the methodology,namely,recording spontaneous and natural spoken conversation from authentic interaction with the permission of the ten male-female couples.Digital record pen with an omnidirectional microphone are placed in the central living area of each couple's home.Then discourse analysis provides data making it possible to support Fishman's claim that women use tag questions and 'you know' not because women are not being really sure of themselves,or are looking to the addressee for confirmation,but because men in a dominant position often refuse to take responsibility for the smooth conduct of interpersonal relations,women use tag questions and 'you know' to elicit and maintain conversations. 展开更多

Objective:Gender-specific integrated health services have long existed in the arena of women’s health care,but men’s health centers(MHCs)have only recently emerged as a novel practice model.Here,we seek to evaluate the prevalence and format of MHCs found in the leading academic medical centers in the United States.Methods:The US News&World Report’s Top 50 Ranked Hospitals for Urology was used as our cohort.Data were gathered on the presence of MHCs and types of providers and conditions treated.An equivalent search was performed for women’s health centers(WHCs).Results:Sixteen of 50(32%)promoted some type of MHC,compared to 49 of 50(98%)offering a WHC.Eight of the top 15 ranked institutions(53%)had an MHC compared to eight of 35(23%)remaining programs.Six of 16 MHCs incorporated providers from a variety of medical disciplines,including urologists,internists,endocrinologists,cardiologists,and psychologists,while another six of 16 MHCs were staffed solely by urologists.Eight of 16 provided services for exclusively urologic issues,four of 16 offered additional services in treatment of other medical conditions,and four of 16 did not specify. 展开更多

According to the existing concrete core samples obtained in site, chloride concentration and porosity of existing normal hydraulic concrete were measured, and chloride diffusivity in existing hydraulic concrete was studied. By Fick’s second law, the chloride diffusion coefficients in the steady diffusion area were calculated. The chloride diffusion of different mix proportion concrete was tested, and chloride diffusion coefficients and porosities of freshly concrete were measured, moreover, the relationship between diffusion coefficient and porosity was analyzed. The results show that the varying law of chloride diffusion coefficient with exposure time of existing concrete can be predicted in a better way by Fick’s second law and water-cement ratios or porosity of concrete and chloride concentration in existing concrete. 展开更多
