Assembly lines are useful for mass production of standard as well as customized products. Line balancing is an important issue, in this regard an optimal or near optimal balance can provide a fruitful savings in the initial cost and also in the running cost of such production systems. A survey of different problems in different types of assembly lines and some of the critical and on going research areas are highlighted here. The provided research information is momentous for the research community in assembly line area to proceed further in the presented issues of assembly lines.

This paper is a detailed exploration of instantaneous poles for a class of two-degree-of-freedom (two-DOF) spherical mechanisms (SMs) with seven links or bars. For two-DOF SMs, the secondary instantaneous poles (the ones which cannot be found by direct inspection) must lie on the specified great circles. For many of these mechanisms, however, some of these great circles cannot be obtained by a direct application of Aronhold-Kennedy theorem. This paper presents geometrical and analytical techniques to locate these unknown great circles for three topologies of seven-bar two-DOF SMs.

从对区域地质调查的任务出发,总结了过去区域地质调查工作的特点,即基本上是沿用传统方式进行的。提出和论述了21世纪中国区域地质调查应有新发展,以适应战略转变的要求,即除去运输、通讯、记录及数字化成图等之外,更应当面向土地资源、矿产资源、地质灾害以及提高环境质量的需要,用现代地学理论指导进行多学科的调查和采集、整理资料,实现3维多参数填图和理论概括,是关系现代地质科学发展的、具有深远战略意义的事。几十年的调查工作已证明深部的地质构造情况与地表层的观察结果是不一样的,与依据地表地质构造情况推测的深层情况也很不同。今后应加强深部探测,发展深部探测技术,取得不同深度层次的高分辨率成像图案,使人们对地球的认识提高到一个新的高度,形成新的空间—时间观念,以更有效地解决我国及地球的资源环境问题。

Township hospitals, the main provider of rural primary healthcare in China, are severely understaffed. International studies on factors influencing rural working are increasing; however, studies on factors affecting the recruitment and retention of health workers in Chinese township hospitals are limited. The current study aims to understand the motivation of health workers and arrive at a systematic framework of pluralistic factors that would help support health workers in terms of receiving posts and remaining in posts in township hospitals. A three-stage integrated quantitative and qualitative methodology was employed. First, a survey on 120 directors of township hospitals was conducted to learn the latest status of health workers in township hospitals and distinguish existing problems. Second, after sending these problems back to the directors, an open-ended pen-and-paper survey was conducted to ask the directors to identify the factors influencing the attraction and retention of health workers in township hospitals. Third, four focus groups were conducted to gauge the underlying reasons. Five problems from the questionnaire survey were recognized, and numbers of thematic factors were identified at the individual, professional, and treatment environment from the pen-and-paper survey and focus group. Similar to other studies, this framing of both non-financial and financial elements affected the attraction and retention of health workers in township hospitals, thereby filling the gap in a Chinese context. Although several factors had been recognized earlier, our findings further highlighted the importance of these factors. Meanwhile, the factors identified in this study were barely explored in literature. This paper identifies and develops multi-faceted factors to call for a bundled package of multidimensional incentives if decision-makers get interested. The evidence-based findings in our study can be used to provide China-specific policy recommendations on how to recruit and retain health workers in rural areas of China.

Systematic reviews and meta-analyses are playing an increasingly important role in clinical research and practice. This study aimed to measure the scientific production of systematic review and meta-analysis from the three major regions of China: the Mainland (ML), Hong Kong (HK), and Taiwan (TW). English articles on systematic review and meta-analysis from ML, HK, and TW from 2001 to 2010 were retrieved from the PubMed database. The total number of articles, impact factors (IF), and articles published in high-impact journals were conducted for quantity and quality comparisons among the three regions. There were 1 587 published articles from ML (1 292), HK (203), and TW (92) during the past ten years. The annual total numbers of articles in the three regions increased significantly from 2001 to 2010 (from 13 to 677). The number of articles from ML has exceeded that from TW since 2001, and surpassed that from HK in 2003. The accumulated IF of articles from ML (3 488.24) was higher than those from HK (493.16) and TW (216.39). HK had the highest average IF of 3.31, followed by ML of 2.90 and TW of 2.85. Researchers from HK published a larger proportion of papers in high-impact journals than those from ML and TW. The Cochrane Database of Systematic Reviews was the most popular journal in China. Chinese authors have been very active to enhance the systematic review and meta-analysis research over the past ten years, especially in ML. The gap between ML and the other two regions has been narrowed. But there is still considerable room for Chinese authors to improve their studies on systematic review and meta-analysis.
