Construction is a project centric industry operating within an environment of considerable complexity and uncertainty (Koskela birth control for women happy order alesse 0.18mg online, 2000) due to the fragmented structure of the supply chain (Picchi birth control pills qatar buy genuine alesse, 2001) and short term birth control for women x x order alesse 0.18 mg overnight delivery, adversarial trading relationships (Barret birth control otc order genuine alesse, 2005). Contrary to manufacturing, the final product has its very own nature because construction projects are unique, static and big in size (Koskela, 2000) whereas manufacturing produces repetitive, large volume and movable products. Furthermore, the workforce in manufacturing has regular workers with high employment security. Due to the long term nature of the employment contract and the long lifecycle of a product, the employees gain job specialisation with high experience. On the other hand, in the construction industry, job security is low and workers perform a range of tasks during a project (Salem et al. The scope of operations in manufacturing is well defined from the beginning and operations plan is in great detail based on many trials. However, construction operations are partly defined and details are unexamined (Howell and Ballard, 1997). Unlike manufacturing activities where the rhythm of production is fundamentally governed by the machines used in the manufacturing processes, construction depends on the management of information and resource flows of mainly labour and non-stationary equipment (Alarcуn, 1997). In construction, contractors generally prefer to rent or lease their machineries (Clough et al. However, in manufacturing, it is preferred to purchase machineries because of the long product life cycle and repetitive nature of production. Unlike manufacturing, there is less protection from environmental conditions for construction work since it usually operates outdoor (Koskela, 2000) which causes interruptions to construction works. Quality in manufacturing is achieved through controlling the processes while quality of construction is primarily related to product conformance based on specifications and drawings (Salem et al. In manufacturing, defective products are largely discarded rather than reworked due to the simplicity and flexibility of the product. In construction, rework is a common practice since only one final product is 356 World Construction Conference 2012 ­ Global Challenges in Construction Industry 28 ­ 30 June 2012, Colombo, Sri Lanka delivered (Salem et al. Moreover, the labour intensity increases the risk of human error and quality issues are widespread in the industry. In manufacturing, manufacturer-supplier relationships are clear, more manageable and open to repetition. The subcontractor performance can highly affect a finished product in construction due to the interrelations between processes. The incapability to improve the productivity level of construction projects is mainly perceived by people in the industry due to project characteristics (Koskela, 2000) and identified differences are summarised in Table 1. Table 1: Differences between the Manufacturing and Construction Work Characteristics Features Manufacturing Construction Type of industry Type of work Mode of production Production volume Production rate Operations Product quality Workers Supplier relationship Layout Environment Process centric Discrete components Machine intensive Large and repetitive Depend on machines used Well defined Assures from process quality Less rework Regular and long term Clear, manageable and repetition Static Mainly indoor, factory setup Project centric Assembly Labour intensive Single and unique Depend on information and resource flows Evolving, learning from the initial stages Conforms to specification High rework Irregular and short term Dynamic and complex Dynamic Mainly outdoor, site setup In the recent past, other industrial sectors have made significant progress through the adoption of "lean thinking" but research investigations show that several obstacles account for the low uptake of lean principles in construction. Many practitioners are resistant to lean principles due to the fact that the industry as a whole is unique (Hook and Stehn, 2008). Therefore they believe that extension of specific manufacturing techniques such as lean to construction is uncertain. Conversely, researchers have listed a number of similarities between the two industries such as both industries consist of socio-technical systems (the combination of human and technical elements) and construction is similar to the manufacturing area of new product development (Kagioglou et al. Koskela (1999) states that lean construction shares the same goals of lean production: elimination of waste, cycle time reduction, and variability reduction. Therefore before generating a range of theories related lean implementation for the construction industry, it is worth to consider the ability to transfer of lean manufacturing practices and theories to the construction industry. To gain an understanding of the differences in lean principle between manufacturing and construction, the fundamental differences between manufacturing and construction had to be investigated. Before converting the principles and techniques, it is good to look at the construction process characteristics through real examples. The direct transfer of knowledge from manufacturing to construction could be possible for some particular types of construction. While previous studies related to lean construction provide some insights, they are inadequate for understanding what actually happens in the construction site particularly in infrastructure, long term project.

However birth control 19th century 0.18mg alesse for sale, these latter approaches have not been tested in humans and may favor cancer development birth control and anxiety cheap 0.18 mg alesse mastercard. Substances that inhibit key signal transduction pathways involved in liver fibrogenesis also have the potential to treat liver fibrosis (20) birth control 50 years ago buy alesse online from canada. They include pentoxifylline (phosphodiesterase inhibitor) birth control for women how are stis discount alesse 0.18 mg without a prescription, amiloride (Na+/H+ pump inhibitor), and S-farnesylthiosalicylic acid (Ras antagonist). The inhibition of the renin-angiotensin system is probably the most promising strategy in treating liver fibrosis. Renin-angiotensin inhibitors are widely used as antifibrotic agents in patients with chronic renal and cardiac diseases and appear to be safe when administered for prolonged periods of time (S14). Little information is available on the use of this approach in patients with chronic liver diseases. Transplanted patients receiving renin-angiotensin system inhibitors as antihypertensive therapy show less fibrosis progression than patients receiving other types of drugs (S16). However, this approach cannot be recommended in clinical practice until the results of ongoing clinical trials become available. The blockade of endothelin-1 type A receptors and the administration of vasodilators (prostaglandin E2 and nitric oxide donors) exert antifibrotic activity in rodents, yet the effects in humans are unknown (90). Different herbal compounds, many of them traditionally used in Asian countries to treat liver diseases, have been demonstrated to have antifibrotic effects (S17). An alternative approach is the inhibition of collagen production and/or the promotion of its degradation (20). Inhibitors of prolyl-4 hydroxylase and halofuginone prevent the development of experimental liver cirrhosis by inhibiting collagen synthesis. The efficacy of these drugs in humans is unknown, and they may result in undesirable side effects. Finally, infusion of mesenchymal stem cells ameliorates experimentally induced fibrosis, which suggests a potential for this approach in the treatment of chronic liver diseases (S18, S19). Promising preliminary results have been recently obtained using different carriers. Sustained virological response is associated with an improvement in liver fibrosis (122). For nonresponder patients, the use of renin-angiotensin system inhibitors is a promising approach. Treatment of the metabolic syndrome in patients with chronic hepatitis C may also decrease fibrosis progression (S23). In patients with alcohol-induced liver disease, the most effective approach is alcohol abstinence (124). For patients with autoimmune hepatitis, immunosuppressant therapy not only decreases inflammation but also exerts antifibrotic effects (S25). No antifibrotic therapy is available for patients with chronic cholestatic disorders. Ursodeoxycholic acid improves biochemical tests in these patients, but its impact on fibrosis is not consistently proven (S26). Future directions the translation of basic research into improved therapeutics for the management of patients with chronic liver diseases is still poor. The role of pluripotential stem cells in hepatic wound healing is one of the most promising fields. Perfusion of these cells may be a potential approach to promoting fibrosis resolution and liver regeneration. Translational research should investigate the molecular mechanisms that cause fibrosis in different types of human liver diseases in order to identify new targets for therapy. In the clinical setting, the identity of the genetic determinants that influence fibrosis progression should be uncovered. Developing simple and reliable noninvasive markers of hepatic fibrosis is an important goal in clinical hepatology and will facilitate the design of clinical trials. Most importantly, the efficacy of antifibrotic drugs known to attenuate experimental liver fibrosis should be tested in humans.

Combination therapy significantly increased the urinary flow rate (Qmax) from baseline when compared with tamsulosin (2 birth control kills babies purchase alesse with paypal. Subjects (n= 209) were randomized to either silodosin 4 mg twice daily or tamsulosin 0 birth control 3 periods a year buy alesse visa. There was no difference in change in Qmax between tamsulosin and silodosin (mean change -0 birth control pills recommended generic alesse 0.18mg online. This was a poor quality trial; blinding birth control guidelines generic 0.18mg alesse, randomization and allocation concealment methodology were not described. This was a fair quality trial but without direct comparison between treatments it does not add any new information. Improvement in urinary flow rate was significantly improved with combination therapy (1. This was a poor quality trial; no description of blinding, randomization or allocation concealment was provided. Tamsulosin was included in the trial as an active comparator but was not compared with tadalafil or placebo. The Efficacy and Safety of Combined Therapy with -Blockers and Anticholinergics for Men with Benign Prostatic Hyperplasia: A Meta-Analysis. A Systematic Review and Meta-analysis on the Use of Phosphodiesterase 5 Inhibitors Alone or in Combination with -Blockers for Lower Urinary Tract Symptoms Due to Benign Prostatic Hyperplasia. The efficacy and safety of alpha-1 blockers for benign prostatic hyperplasia: an overview of 15 systematic reviews. Monotherapy with Tadalafil or Tamsulosin Similarly Improved Lower Urinary Tract Symptoms Suggestive of Benign Prostatic Hyperplasia in an International, Randomised, Parallel, Placebo-Controlled Clinical Trial. Has the client tried and failed a 2-month trial of a covered alternative alpha blocker (terazosin, doxazosin, prazosin, tamsulosin)? Yes: Approve an alpha blocker only for 1 year No: Deny until client has tried and failed a covered alternative No: Go to #10 9. Does client have a diagnosis of unspecified urinary obstruction or benign prostatic hyperplasia without obstruction? Is the request for an alpha blocker, and does client have a diagnosis related to functional and mechanical disorders of the genitourinary system including bladder outlet obstruction? Yes: Go to #2 No: Go to #3 Yes: Recommend against combination therapy exceeding 1 year Yes: Approve for 1 year No: Approve for the shorter of 1 year or length of the prescription No: Go to #4 3. Combination therapy also provided significantly greater symptom improvement than either monotherapy at 4 years. Safety and tolerability of dutasteride plus tamsulosin was consistent with previous experience of this combination and with the monotherapies. The results in the European subgroup are generally consistent with those in the overall study population. Although patients receiving silodosin had a significantly higher incidence of abnormal ejaculation (9. Tamsulosin treatment resulted in a significant reduction in mean systolic blood pressure (-4. Following screening and washout, if needed, subjects completed a 4-wk placebo run-in before randomisation to placebo (n = 172), tadalafil 5 mg (n = 171), or tamsulosin 0. The International Index of Erectile Function­Erectile Function domain improved versus placebo with tadalafil (4. This study was limited in not being powered to directly compare tadalafil versus tamsulosin. Date: 189 the Combination of Avodart and Tamsulosin study was a 4-year, randomized, double-blind study of the efficacy and safety of dutasteride and tamsulosin, alone or in combination, in men with moderate-to-severe benign prostatic hyperplasia. In this post-hoc investigation, we analyzed primary and secondary end-points from the Combination of Avodart and Tamsulosin study in Asian (n = 325) and Caucasian men (n = 4259). The incidence of acute urinary retention or benign prostatic hyperplasiarelated surgery did not differ significantly between treatment groups in the Asian subpopulation. In Caucasian men, the incidence of acute urinary retention/benign prostatic hyperplasia-related surgery was significantly lower in the combination therapy group compared with the tamsulosin monotherapy group (P < 0.

Keywords: Front-End Planning birth control viorele buy alesse 0.18mg on line, Project Performance, Construction Industry, Singapore. While professionals in the construction industry understand the need for planning, it has not been well materialised due to the fact that changes to original plans are inevitable. As such, making a significant effort for planning tends to be considered a challenging process as it also requires vast capital, human resources and time. More than often, people in the Singapore construction industry perceive that rare value is found in project planning, and they give such excuses that "We do not have sufficient time to plan now, and we will have lots of time to fix things up later. The negative practice involves estimating an artificially high earned-value for the early activities in order to improve the cash flow and collect the profit at the beginning of the project. However, this term is widely used in planning and execution in the industrial projects sector to stress the fact that the early activities in a project actually do have a high value and will have a lasting effect on the project" (Griffith and Gibson, 2001)). The ability to execute the planning effort with the right team and the right dedication of resources is paramount to project success (Gibson, 1995). It is not a job of just one person, but multiple parties who provide inter-related project information. For instance, when estimating construction cost, the quantity surveyor requires a description of the project scope prepared by the architect as defined by the client, indicating that outputs from one party become inputs for another. It is usually a project manager or a project planner who will get advice from various consultants and specialists (engineers, architects, quantity surveyors, etc. He/She must consider all possible project alternatives to identify an optimum project configuration. All pre-project personnel involved in the process need to understand what activities occur, and what their roles and responsibilities are in the process (Gibson et al. The project, business, and operations managers need to understand that they have different views concerning project success and project objectives. These views need to be communicated, and project representatives should agree on project objectives. Other factors such as poor business decisions, unreliable data, or other assumptions can also affect the success of the project. This includes the identification of license agreements, testing procedures, and any security/secrecy requirements that may be needed for the project. Project scope definition, the process by which projects are selected, defined and prepared for definition, is one key practice necessary for achieving excellent project performance (Merrow and Yarossi, 1994). Extraordinary risks are many times the result of unresolved scope issues or unforeseen conditions (Smith and Bohn, 1999). In addition, a comprehensive project execution plan should be developed to carefully identify how the project will be executed. These studies typically consider: building use; business justification; business plan; economic analysis; facility requirement; future expansion or alteration considerations; site selection considerations; and project objectives in order to address the mission need (Federal Facilities Council, 2003). Cleland and Ireland (2002) identified that decisions made early in the project process will, ". Experienced personnel within the construction industry believe that planning efforts conducted during the early stages of a project have much more effect on the success of the project. Many potential problems are identified proactively before they can greatly affect project cost and schedule. Also, successful planning identifies which areas within the project need greater definition prior to execution. As the project enters the execution phase, the team has less influence to make low cost changes over the project (more costly to implement changes on the project). Figure 2 also illustrates this and the research done by Gibson and Hamilton (1994) also supports this relationship, arguing that more effort in project planning results in more successful projects. Enhanced preparation can reduce the amount of change orders, misunderstandings, litigation and delays during project execution.
