The Composition and Case Study of the Nurses’ Voluntary Turnover Cost in China  [PDF]
Min Li
Modern Economy (ME) , 2017, DOI: 10.4236/me.2017.86058
Abstract: Nurse is the largest number of four medical personnel, and the stability of the nurses is directly related to the quality of medical service, but countries around the world are faced with the high turnover rate of nurses [1]. At present, Chinese researches on the issue of nurses resignation mainly focus on the analysis of the variables and causes of nurses resignation, while there is few research related to the turnover costs of nurses which the managers focus most. All these problems lead to there is still no consensus and cognition on composition and measurement methods of turnover costs and the harm of the organizations. Based on the literature research, this paper summarizes the composition and measurement of the voluntary turnover cost of Chinese nurses, and draws the main constituent elements and feasible measurement methods of the nurses’ voluntary turnover cost. Furthermore, this paper takes a military hospital in Beijing as an example and shows the composition and measurement methods of turnover cost by the actual measurement of the nurses’ turnover costs in this hospital. Hope this paper can provide some reference for the future theoretical research and medical practice.

Creative Education (CE) , 2017, DOI: 10.4236/ce.2017.813146
Abstract: With the advancement of times and development of technology, the traditional teaching mode has gradually revealed some drawbacks. Therefore, a new teaching mode is needed. Flipped class, as one of the new teaching modes which can improve the students’ initiative and self-discipline, has attracted colleges and universities’ attention and exploration. Based on the teaching reform practice of the flipped classroom teaching mode of the basic management course in universities, this paper elaborates the significance and current situation of the flipped classroom practice in universities, and explores the specific schemes, procedures as well as the future development direction of the flipped classroom teaching mode of the basic management course. Through the analysis of these problems, we hope to contribute to the reform of flipped class teaching mode in universities, and provide some references for later research.
An Investigation and Analysis of Information Overload in Manager's Work  [PDF]
Tao Li, Min Li
iBusiness (IB) , 2011, DOI: 10.4236/ib.2011.31008
Abstract: The problem of information overload in management field has been receiving increasing attention, while there are less empirical researches now. This paper proposes a conceptual model and some operational variables, in which information overload is as an intervening variable between the factors of causes and impacts. An investigation and analysis has been conducted from a selected sample of managers. This research suggests that work efficiency and work quality are both not strongly connected with information overload. We also find that the main causes of information overload are the work interruption and work time pressure but the amount of information.

Blunt Traumatic Pericardial Rupture
—Case Report and Literature Review
 [PDF]

Hongbin Wang, Min Li
Surgical Science (SS) , 2013, DOI: 10.4236/ss.2013.410086
Abstract:

Pericardial rupture following blunt chest trauma is rare and associated with high mortality rate ranging from 30% to 64%. We review 42 cases which have been reported in the literature in last 17 years and report a case of our own. We have found that 83% of the cases were men with a mean age of 49 years. The most frequent cause was traffic accidents (79%). Preoperative diagnosis of traumatic rupture of the pericardium has been improved in recent 17 years, and the result is satisfactory. Early detection, timely treatment is the key. Pneumopericardium may be a valuable radiographic clue for diagnosis. The management of pericardial rupture is mainly to avoid the risk of cardiac strangulation or acute tamponade. If the injury is recognized timely, treatment is simple and effective.

Study on Survival Strategies of Farmers Engage in Small-Scale Household Cultivation of Edible Mushrooms: Take Shandong Province as an Example  [PDF]
Min Li, Jilian Hu
Modern Economy (ME) , 2014, DOI: 10.4236/me.2014.512100
Abstract:

Small-scale household production of edible mushrooms by farmers is the major source of edible mushrooms in China. However, large-scale enterprises who engage in commercial cultivation of edible mushrooms has been growing at a relatively fast pace, bringing about challenges for small-scale farmers. With the purpose of help maintain small-scale farmers’ ability to survive in this fiercely competitive landscape, this paper first analyzes their competitive advantages, disadvantages and survival strategies, employing the methods of field survey and comparative observation. Based on these analyses, suggestions concerning how to strengthen the survivability of small-scale farmers are proposed, focusing on further lowering production cost and optimizing cooperative modes.

Li Min Lim, Kuldip Singh
Open Journal of Obstetrics and Gynecology (OJOG) , 2014, DOI: 10.4236/ojog.2014.415130
Abstract: Background: Medical and surgical methods are available for abortions in both the first and second trimester. Aim: To review the evidence base and current recommendations for available methods of abortions in first and second trimesters. Methods: Extensive literature search and review of available guidelines were done. Results: In the first trimester, medical methods are recommended below 7 weeks gestation while vacuum aspiration is an appropriate method between 7 to 12 weeks gestation. In the second trimester, the three methods of abortion available are dilatation and evacuation, intrauterine instillation of abortifacients and administration of systemic abortifacients. Conclusion: The choice of techniques depends on many factors including uterine volume, operator experience, patient preference, medical history and indication for abortion.
Improved Detection of Cervical Cancer and High Grade Neoplastic Lesions by a Combination of Conventional Cytology and DNA Automated Image Cytometer  [PDF]
Zuming Li, Min Zhang, Hua Li
Journal of Cancer Therapy (JCT) , 2010, DOI: 10.4236/jct.2010.12008
Abstract: OBJECTIVE: To reduce false-negative rates of population based cervical screening programs employing conventional cytology in combination with automated DNA image cytometer. METHODS: Involved cervical samples from a total of 3603 women were taken by a cervix brush and then placed into a fixative solution. The cells were separated from mucus by mechanical and chemical treatment after which they were deposited onto microscope slides by a cytospin. Two slides were prepared from each case; one slide was stained by Papanicolaou stain for conventional cytology examination, while the other slide was stained by a DNA specific and stoichiometric stain. The latter slide was used to determine the relative amount of DNA in the cell nuclei in order to assess the ploidy status of the epithelial cells. Enrolled in the study, 157 women were followed by colposcopy examination where punch biopsies were taken from the visible lesions or from suspicious areas. The results of the conventional cytology were then compared to the DNA image cytometer for all samples. RESULTS: Histopathology diagnosed 51 lesions from the 132 biopsied cases as CIN2 or higher, including 27 CIN2, 16 CIN3 and 8 invasive cancers. Conventional cytology correctly identified 29 of the 51 high grade CIN and in-vasive cancer, while DNA image cytometer correctly identified 38 high grade CIN and invasive cancer using the crite-rion that at least three cells were found on the slide that contained DNA amount in excess of 5c. 42 out of 51 high grade CIN and invasive cancer were found by conventional cytology in combination with DNA image cytometer. Sensitivities were 56.8%, 74.5% and 82.4%, while specificities were 86.2%, 81.5% and 81.5% in conventional cytology, DNA image cytometer and combination both cytology and DNA image cytometer respectively. CONCLUSION: The study demon-strated that screening for high grade neoplastic lesions and cervical cancer by DNA image cytometer or combination of conventional cytology and DNA image cytometer is more sensitive than conventional screening approach.

Advances in Operations Research , 2012, DOI: 10.1155/2012/483479
Abstract: This paper presents modified halfspace-relaxation projection (HRP) methods for solving the split feasibility problem (SFP). Incorporating with the techniques of identifying the optimal step length with positive lower bounds, the new methods improve the efficiencies of the HRP method (Qu and Xiu (2008)). Some numerical results are reported to verify the computational preference. 1. Introduction Let and be nonempty closed convex sets in and , respectively, and an real matrix. The problem, to find with if such exists, was called the split feasibility problem (SFP) by Censor and Elfving [1]. In this paper, we consider an equivalent reformulation [2] of the SFP: where For convenience, we only consider the Euclidean norm. It is obvious that is convex. If and , then solves the SFP. Throughout we assume that the solution set of the SFP is nonempty. And thus the solution set of (1.1), denoted by , is nonempty. In addition, in this paper, we always assume that the set is given by where is a convex (not necessarily differentiable) function. This representation of is general enough, because any system of inequalities , where are convex and is an arbitrary index set, can be reformulated as the single inequality with . For any , at least one subgradient can be calculated, where is a subgradient of at and is defined as follows: Qu and Xiu [2] proposed a halfspace-relaxation projection method to solve the convex optimization problem (1.1). Starting from any , the HRP method iteratively updates according to the formulae: where is an element in , and is the smallest nonnegative integer such that The notation denotes the projection of onto under the Euclidean norm, that is, Here the halfspace contains the given closed convex set and is related to the current iterative point . From the expressions of , the projection onto is simple to be computed (for details, see Proposition 3.3). The idea to construct the halfspace and replace by is from the halfspace-relaxation projection technique presented by Fukushima [3]. This technique is often used to design algorithms (see, e.g., [2, 4, 5]) to solve the SFP. The drawback of the HRP method in [2] is that the step length defined in (1.9) may be very small since . Note that the reformulation (1.1) is equivalent to a monotone variational inequality (VI): where The forward-backward splitting method [6] and the extragradient method [7, 8] are considerably simple projection-type methods in the literature. They are applicable for solving monotone variational inequalities, especially for (1.11). For given , let Under the assumption the
