Minimally UKA is one of the recent and the majority successful procedures in modern orthopedics for the osteoarthritis which is spreading throughout the worldwide. Recently, many orthopedic surgeons are expanding their abilities in this field. However, it needs good knowledge and well experience for the successful clinical outcomes. The minimal invasive approach is more efficient for short hospital stay and faster postoperative recovery with low morbidity of the patients after UKA. The aim of this article is to emphasize the steps in UKA based on modern facts: function of knee joint, diagnosis, less invasive approach for medial condylar replacement, radiographic evaluation, and earlier recovery, selecting the patient and implant survivorship with review of surgery.展开更多

In terms of employment protections for people with disabilities, it is important to focus on effective legal implementation, utilizing legal rulings to limit employment discrimination against people with disabilities. Educational protections are an important precondition for enabling people with disabilities to live with dignity; it should be guaranteed that people with disabilities are provided ＂reasonable accommodation＂ in educational conditions. A barrier-free environment is a necessary condition for social integration of people with disabilities. At the same time, it also benefits other members of the society such as the elderly. Through rehabilitation and exercise, most people with disabilities can return to the society to a significant degree. China should gradually expand the legislative scope of rehabilitation service fee reductions and legal categories of auxiliary appliances, issuing guiding documents that provide specifications for the relevant ＂dormant＂ legal provisions.展开更多

It is one of the most reliable, most effective and important means of ocean monitoring technology. In this paper, the classification, main theory and technology system of marine data buoy are summarized. The typical technological breakthrough of the development of marine data buoy in recent years is summarized. The composition and application of marine monitoring network in China was introduced, and the gap between the technology of China＇s marine data buoy and the international advanced countries is compared.Combined on the situation and demand of China＇s current situation and needs, the development trend of marine data buoy and buoy monitoring network are expected.展开更多
