Methods From a community-based screening program a total of 158 patients with presenting visual acuity of less than 6/18 on either eye due to age-related cataract were informed about the possibility of surgical treatment. These patients were interviewed and re-examined 36 to 46 months after initial screening. The main reasons for not accepting surgery were obtained using a questionnaire. Vision function and vision-related quality of life scores were assessed in those who received and did not receive surgery. Results At the follow-up examination 116 of the 158 patients were available and 36 (31.0%) had undergone cataract surgery. Cases who chose surgery had higher education level than those who did not seek surgery (OR=2.64, 95% CI: 1.08-6.63, P=0.02). There were no significant differences in vision function (P=0.11) or quality of life scores (P=0.16) between the surgery group and the non-surgery group. Main reasons for not having surgery included no perceived need (50.0%), feeling of being "too old" (19.2%), and worry about the quality of surgery (9.6%).

This region has lost its leading place since the reform and opening up, and became a backward region by contrast with the coastal areas. This paper elaborates the evolutionary process of the old industrial base of Northeast China, analyses the main reasons for the decline, gives a preliminary evaluation on the revitalizing polices in recent years, and points out major long-term challenges for future revitalization. It concludes that for Northeast China, a relative declining area: 1) it is indispensable to get the long-term policy support from the central government; 2) system reform and structure adjustment are the crucial strategies, particularly the reform of the large and medium state-owned enterprises; and devel-oping new industries is as important as upgrading traditional advantaged industries; 3) the local governments should play an indirect role, avoiding from any unnecessary intervention on economic activity; and 4) social security and investment climate must be improved simultaneously. In addition, the author stresses that the lack of knowledge on the nature of old industrial base had led to failures of the past initiatives, and revitalizing the old industrial base should be treated as a holis-tic regional project including economy growth, society progress and environment improvement.展开更多

The mismatch is exhibited at the supply side and arises from structural contradictions and must be addressed through reforms. Supply-side structural reforms can be analyzed at the levels of firms, industries and government to arrive at theoretical and systematic conclusions that offer practical guidance. Based on this perspective, this paper proposes policy recommendations on how to deal with zombie firms, reduce cost for manufacturing companies, deepen SOE reforms, eliminate overcapacity, implement "Made in China 2025" and Internet+ strategies, promote Beijing-l^anjin-Hebei integrated development, as well as develop the Yangtze River Economic Belt and the old industrial bases of the northeast.展开更多

According to the investigation and com- parative analysis on more than 900 elderly people, who usually exercise in public parks in Beijing City, we have found out several new features of elderly people's outdoor recreation in Belting: the increase of the leisure time, the expansion of leisure space, the in- dividuation of interest and the diversification of consumption. The leisure life quality evaluation index system of urban elderly people can be built based on these analyses. In order to accommodate the development tendency of elderly people's demand for leisure diversification, we should strengthen the organization and manage- ment of elderly people's leisure activity in urban construction, and pay more attention to function complementation between commu- nities and parks.展开更多

The survey underlying this study was conducted in Muang district, Khon Kaen province, Thailand. Eighteen subdistricts were interviewed in the study area. Data were collected in two areas of Khon Kaen province, that are, the city of Khon Kaen and the outside Thesaban Nakhon Khon Kaen. The random sample consisted of 386 elders: 112 elders lived in the city of Khon Kaen and 234 elders lived outside Thesaban Nakhon Khon Kaen, Muang district, Khon Kaen. The analysis of the demand on elderly welfare gave an interesting result that the elders demanded on monthly income to support living cost and medical services at high level; The demand on housing was at low level; The demand on education, religion and culture the demand on club, sport and entertainment, and the demand on job and art were at the moderate level; The main problem of elderly welfare arrangement was the scarcity of budget support, the weakness of elder health, and activities announcement. The analysis of pattern of elder welfare: The case study of elder care identified that 31.87 percent of the elders had demand on elder care. Price of the elder care at 100 Baht per day was mostly selected about one-fourth of all the case occurred. Female elder selected the elder care at 100 Baht per day, while male elder choose at a higher price level, which were 200 Baht per day and 150 Baht per day respectively. The female elder care was the most popular. The elder care age between 30-39 years was mostly selected. Finally, most of elders purposed the working day of the elder care depend on their appointment.展开更多

This study indicates that adult sons' setting up their own homes is a precondition for elderly couples' becoming "empty nesters," a situation which in turn leads to contracts for "care rotation." Many factors, including marketization, the transformation of social structure and the rising status of daughters-in-law in family decision-making are responsible for elderly people's loss of their role in such decision-making. Therefore, during the life course of the elderly, "care rotation" is in fact an arrangement imposed on elderly parents rather than their own choice.展开更多
