Ahmad Tarhini, Shelby L. Corman, Sumati Rao, Kim Margolin, Xiang Ji, Sonam Mehta, Marc F. Botteman
Journal of Cancer Therapy (JCT) , 2015, DOI: 10.4236/jct.2015.610091
Abstract: Background: To describe healthcare costs, excluding ipilimumab drug costs, in patients with advanced melanoma receiving ipilimumab in the US community practice setting. Methods: This was a retrospective chart review of unresectable stage III/IV melanoma patients who received first-line ipilimumab monotherapy between 04/2011 and 09/2012. Healthcare resource utilization included inpatient, emergency, specialist and hospice visits, laboratory tests, radiation, surgeries, and nursing home stays. Publicly available US unit costs were applied to each resource type to estimate costs, which were analyzed by time periods: during ipilimumab treatment, post-ipilimumab treatment (post-regimen), and within 90 days prior to death (pre-death). Generalized linear mixed models were used to explore cost predictors during the treatment period, on a per-dose-interval basis, defined as the time between ipilimumab doses. Results: Data were abstracted from 273 patient charts at 34 sites. Excluding ipilimumab drug costs, total monthly costs during the treatment regimen, post-regimen, and pre-death periods were $690, $2151, and $5123, respectively. Total healthcare costs were 27 times higher during dose intervals with a grade 3/4 adverse event compared with intervals without a grade 3/4 adverse event. Eastern Cooperative Oncology Group performance status ≥ 2 (vs 0) was also associated with significantly higher cost per dose interval. Conclusions: In this population, monthly costs exclusive of drug were significantly lower during the treatment period than in subsequent periods. Unfavorable ECOG PS was associated with significant increases in cost per dose interval. Grade 3/4 adverse events were associated with a marked increase in healthcare costs, but occurred in a small proportion of dose intervals.
A Promising Way of Resource Utilization in China: Converting Waste Oils and Fats to Biodiesel  [PDF]
Shitao Liu, Congping Wu
Journal of Power and Energy Engineering (JPEE) , 2014, DOI: 10.4236/jpee.2014.26001
Abstract:

Most of Biodiesel, a clean burning alternative fuels for diesel engines is made from renewable agricultural feedstock, such as rapeseed oil, soybean oil etc., but less expensive biodiesel can also be made from waste oils and fats, including recycled restaurant grease and animal fats. Because of the eating habit of the nation and diet culture in china, restaurant-kitchen garbage is increasingly serious and has negative impact on environment and food security. The utilization of waste oils and fats to biodiesel provide a promising way of how to appropriately and effectively dispose of restaurant-kitchen garbage. This paper first reviews the development status of biodiesel industry, then introduces the novel technology of tubular reaction for producing biodiesel from waste oils and fats on the typical industrialization case in Kunshan. All these efforts are expected to provide a viable development path for our waste oil to produce biodiesel and worth reference to waste oils and fats recycling and reuse.

Open Journal of Psychiatry (OJPsych) , 2013, DOI: 10.4236/ojpsych.2013.31A011
Abstract: Background: Patients with generalized anxiety disorder (GAD) are among the highest users of healthcare resources. The broadening of the DSM-IV criteria for GAD has been a subject of controversy in the literature, but its consequences have not been analyzed to date. Objective: The purpose of this study was to analyze how the broadening of the DSM-IV criteria affects healthcare resource utilization and related costs. Methods: A multicentre, prospective, observational study was conducted in randomly selected outpatient psychiatric clinics between October 2007 and April 2008. Patients diagnosed according to DSM-IV or broader criteria (1 month of excessive or non-excessive worry and only 2 associated DSM-IV symptoms) for the first time were consecutively enrolled. Socio-demographic data, healthcare resources and corresponding costs were collected over a 6-month period. Results: A total of 3549 patients were systematically recruited, 1815 in the DSM-IV criteria group (DG) and1264 inthe broad criteria group (BG). Treatments prescribed were similar for antidepressants in both groups (77.0% in the DG vs. 75.3% in the BG, p = 0.284), and slightly higher in the DG for benzodiazepines (71.5% vs. 67.2% respectively, p = 0.011) and anticonvulsants (72.1% vs. 67.0% respectively, p = 0.002). Healthcare resource utilization was statistically reduced to a similar extent in both groups as a consequence of treatment, yielding a reduction in the cost of illness of €1196 (SD = 1158) and €1112 (SD = 874) respectively; p = 0.304, over a 6-month period. Conclusion: The broadening of the GAD criteria could lead to earlier diagnosis not necessarily associated with an increase in healthcare resource utilization or costs to the National Health System in the six-month follow-up.

Revista Espa?ola de Salud Pública , 2001, DOI: 10.1590/S1135-57272001000300008
Abstract: background: in recent years, patient classifications systems (pcs?s) have been implement in spain for the purpose of gauging the ?hospital product?. however, the most conventional systems are not very well-suited to the senior citizen population, among whom illness-related disability is a determining factor with regard to explaining the usage of resources and the results of the health care provided. therefore, the idea was brought forth of implementing a system in units providing senior citizen care which would entail this parameter, that is, the resource usage groups (rug?s), analyzing the characteristics and differences in the rug-related spread in four geriatrics units. methods: a cross-sectional study based on consecutive cutoff points in periods longer than the average stay in each unit, the patients admitted in the acute care units and average stay in the geriatrics unit of the hospital monte narango (hmn) (n=318), hospital central de la cruz roja (hccr) (n=384), hospital general de guadalajara (hg) (n=272) and hospital virgen del valle (hvv) (n=390), with regard to the spread thereof according to the rug-t18 classification. the possible differences among the hospitals in question were analyzed by means of the chi-square statistical test (spss for windows). results: for the overall sample, the patients were divided into groups r, s and c of the classification, groups p and b being represented to a very small degree, differences having been found to exist among the different hospitals. hence, the hccr is that which handles the largest percentage of patients in the r group (47.64% vs. 23.66% at hmn; 20.57% at hg and 20.53% at hvv) and a smaller percentage of patients in the s group (3.12% vs. 6.40% at hmn; 9.92% at hg and 9.76% at hvv) and the c group (48.94% vs. 76.29% at hmn; 66.89% at hg and 68.36% at hvv). differences were likewise found to exist in the individual analysis for the acute care units and average length of stay. conclusions: the resource usage g

African Zoology , 2011,
Abstract: The aardwolf, Proteles cristata, is a highly specialized myrmecophagous carnivore that feeds almost exclusively on termites of the genus Trinervitermes. Here we report data from an ongoing analysis of aardwolf diet, where we documented remains of sun spiders and scorpions in aardwolf scats. Although the prevalence of these items was low, with sun spiders recorded in nine and scorpion remains in one of 246 scats, our observations suggest that aardwolves opportunistically feed on larger prey than previously thought. However, our observations do not suggest that aardwolves utilized these large prey items as alternatives to their main food resource during periods of food scarcity. Therefore, we suggest that the adaptive advantages of such opportunism may be small, but that the observed behavioural plasticity could be advantageous under specific environmental conditions and therefore is maintained as a behavioural trait.

Asian Journal of Plant Sciences , 2003,
Abstract: The study was carried out to assess the input use pattern, comparative profitability and resource utilization to cabbage cultivation in different growing periods. The highest gross return as well as net return was obtained from pre-rabi period of cabbage cultivation. The lowest gross return and net loss was obtained from late-rabi period of cabbage cultivation. The study revealed that cabbage cultivation is more profitable in pre-rabi period and least profitable (actually negative profitable) in the late-rabi period. The benefit cost ratio was the highest for pre-rabi period in both variable cost and total cost basis. Return to labour was calculated highest for pre-rabi cultivation indicating best use of highest cost involvement input. Marginal rate of return was found 1667% for pre-rabi cultivation which implies that taka one hundred additional investment to pre-rabi rather than optimum-rabi will provide additional taka 1667 to the growers.
Correlation Based VMS Placement Resource Provision
Zar Lwin Phyo,Thandar Thein
International Journal of Computer Science & Information Technology , 2013,
Abstract: In Virtualized Data Center (VDC), a single Physical Machine (PM) is logically divided into one or moreVirtual Machines (VMs) that share physical resources. Therefore, dynamically resource provisioning playsan important role in VDC. Moreover the resource provider would like to maximize resource utilization,which forms a large portion of their operational costs. To achieve this goal, several consolidations can beused to minimize the number of PMs required for hosting a set of VMs. However, consolidation is oftenundesirable for users, who are seeking maximum performance and reliability from their applications.These applications may indirectly increase costs due to under-provisioning of physical resources.Moreover frequent Service Level Agreement (SLA) violations result in lost business. To meet SLArequirements, over provisioning of resources is used. However, if the services do not use all the CPU theyhave beenallocated;the provider will suffer from low resource utilization, since unused resources cannotbe allocated to other services running in the provider. Therefore VM provisioning is the most vital step indynamic resource provisioning. In this paper, correlation based VMs provisioning approach is proposed.Compared to individual-VM based provisioning, correlation based joint-VM provisioning could lead tomuch higher resource utilization. According to the experimental results, proposed approach can savenearly 50% CPUresource in terms of overall CPU utilization

Journal of Software , 2011, DOI: 10.4304/jsw.6.11.2282-2291
Abstract: A resource management methodology for collaborative computing systems over multiple virtual machines (CCSMVM) is presented to increase the performance of computing systems by improving the resource utilization, which has constructed a scalable computing environment for resource on-demand utilization. We have designed a resource management framework and a prototype to improve resource utilization rate, reduce computing systems overheads and maintain workloads balancing, whose key technologies include resource planning, resource allocation, resource adjustment and resource release. The experiments have verified the feasibility of our prototype and the results of system evaluations show that the time of resource allocation and resource release is proportional to the quantity of virtual machines, but not the time of the virtual machines migrations. Our study on resource management methodology has some significance to the optimization of the performance in virtual computing systems.

Abstract:

随着全球气候变迁的影响日益显著,不论台湾还是中国,在水资源管理上,从政策到制度都有许多不足之处,因此,使得原本就处于极易出现干旱灾害的环境,更加的不稳定。水资源不足已是大家公认的事实,在降雨开源不可期待的情况下,只有从储水与废水再生等途径寻求新的供应源。自迈入21世纪以后,人口迁徙已成常态,都市化成为趋势,水资源的消耗更是大增,废水的产量也有增无减。所以,采用生态工法,实现就地取材,减少碳足迹,同时增加生物栖息的空间,依此建构人工湿地土地处理系统,在低成本、环境冲击小的考虑下,完成污水再生,并将再生水用于浇灌、地下水补注及冲厕杂用等,如能因应地区特性与需要,把生态旅游与环境教育纳入规划,则水资源可持续利用的意义将更加完备。

Water Resources Management has assumed greater significance in Taiwan and China as a result of the impact of global climate change. However, from policies to actual operation models and systems, several problems are identifiable. Hence, under current water resources management interventions, it has been difficult to deal with drought disasters. It is a generally accepted fact that water storage and wastewater regeneration are the only ways of seeking new sources of supply when there is a water shortage, and water shortage has become an even more pressing concern because of urbanization. In the 21st century urbanization has still shown no signs of slowing down and further population migration to cities or the rampant development of a city-style life has led to an even greater consumption of water resources and an elevated increase in the output of waste water. It is within this context of a high water shortage that ecological engineering methods become very important. Ecological engineering allows for the realization of local resources, reduces carbon footprints, and increases habitat space. Using ecological engineering, an artificial wetland treatment system can be built that allows for waste water regeneration and the use of reclaimed water while decrease the environmental impact and cost. If ecological engineering programs also take into account regional characteristics and needs and if ecological tourism and environmental education are also included in the overall plan, sustainable utilization of water resources will be greatly enhanced.
