A Frame Procedure for Multiple Criteria Selection of IT Products and Services
Authors: Čančer Vesna 
Published: September 2013

Abstract
In an information society, the Information Technology (IT) infrastructure of enterprises is important for their performance. Since in the last few decades the Multiple Criteria Decision Making (MCDM) methods have already turned out to be very applicable in solving problems, this article explores the particularities of the frame procedure for MCDM by using the group of methods based on assigning weights in the selection of IT products and services in enterprises. Special attention is given to the methods for establishing the judgements on criteria‘s importance, based on the interval scale. The procedure is completed for considering interactions - synergies and redundancies - among criteria, which can strengthen the decision making basis in the selection of the most appropriate IT product or service. The applicability of the above mentioned frame procedure is illustrated via a reallife case - the selection of the most appropriate storage array

Published: September 2013

Abstract
Accounting is the social science that developed and constantly improved in order to meet the information needed for each stage of the society evolution. In its turn, the financial reporting system was frequently reconsidered in order to harmonize the supply and demand for accounting information. The main objective of this study is to create a fresco of the financial reporting system in Romania, during the last two decades, which is intended to highlight the advantages and limitations of different accounting rules with direct impact on the financial communication process. The present situation demonstrates that the National strategy for improving the financial reporting of private economic entities, mostly based on drafting the individual annual financial statements of public interest entities in accordance with IFRS requirements, encountered certain difficulties in the implementation process.

Published: September 2013

Abstract
Measuring customer satisfaction is a very important aspect of marketing strategy. For the organizational's survival in the long run it is indisputable to have the ability to retain the customers. Retaining customers is more profitable than attracting new ones because it is easier to sell a product or service to a someone who has already used it, rather than someone to whom is product or service completely unknown. In order to measure customer satisfaction primary datas were collected using a test method on a sample of students, by a questionnaire in a physical form, analyzing the basic elements of educational process. Also, by researching relevant national and international professional and scientific literature the test method was described, and all of its models. Finally, in the conclusion, the basic thoughts about the paper are revealed through the presentation of practical advantages and disadvantages of marketing concept of satisfaction, and reviewing recent trends in communication with students.

Abstract
The cooperative form of management is an essential part of the social economy. One of the most important elements in supporting social entrepreneurship is the problem of efficiency of different kinds of support. This paper presents an assessment of the effectiveness of social cooperatives in the traditional way, using the concepts and measures typical for-profit enterprises. The main objective of the research was to assess the effectiveness of financial aid, received by social cooperatives. The subject of the study were twenty social cooperatives, created from 2005 to 2010 in one of the Polish region (Warmia and Mazury). The study shows that there is some level of support, that allows to develop Polish social cooperatives.
Lifetime of a soluble solid particle in a stagnant medium: approximate analytical modelling involving fractional (half-time) derivatives
Authors: Hristov Jordan 
Published: September 2013

Abstract
Approximate analytical solutions concerning lifetime of soluble solid particles in an unbounded stagnant medium have been developed by simple application of fractional half-time derivative in the Riemann-Liouville sense to express the relationship between the net surface mass flux and the concentration at the interface. The solutions start with the initial formulation of Rice and Do on the time-depletion of the radius of a spherical particle expressed through terms including the solubility parameter as the only key parameter controlling the process of dissolution. The two approximate developed solutions use different scaling and dimensionless variables: The 1st solution is developed by an introduction of a similarity variable [xxx] while the 2nd solution applies the classical scaling using the initial sphere radius as a length scale that leads to dimensionless radius r = R/R0 and time τ = Dt/R0
2. Both solutions provide approximate relationships close to that of Rice and Do.
Complexation of poly(ethylene glycol) with poly(ethyl methacrylate-co-N-vinyl-2-pyrrolidone) gel based on hydrogen bonds
Authors: Liu Guoqin 
Published: September 2013

Abstract
The complexes of poly(ethyl methacrylate-co-N-vinyl-2-pyrrolidone) (P(EMA-co-VP)) gel with poly- (ethylene glycol) (PEG) stabilized by the hydrogen bonds were prepared. It was found that both the concentration and the molecular weight of PEG have a strong effect on the P(EMA-co-VP) gel. When PEG was introduced into the P(EMA-co-VP) gel, the glass transition temperatures (Tg) of the complexes decreases with the decreasing of PEG molecular weight. In such a system, the maximum molecular weight of PEG required for the complex formation is no more than 2000, and P(EMA-co-VP)/PEG complexes are a homogeneous amorphous phase, which was studied by FTIR, XRD, TEM, and DSC.
Effect of temperature on o-cresol methylation in a fluidized bed of commercial iron-chromium catalyst TZC-3/1
Authors: Berkowicz Gabriela , Żukowski Witold , Baron Jerzy 
Published: September 2013

Abstract
The paper presents the results of the synthesis of 2,6-dimetyhlphenol (26DMP) from o-cresol. The target compound is an important substrate for polymer chemistry. Due to a large amount of o-cresol which is generated as a by-product, during the synthesis of 2,6-dimethylphenol from phenol, the methylation of o-cresol to 2,6-dimethylphenol should be examined as a separate process. The alkylation of o-cresol was carried out in a fluidized bed of commercial iron-chromium catalyst TZC-3/1. Undesirable decomposition of methyl alcohol on the catalyst generates a number of environmentally dangerous by-products such as methane, carbon dioxide, carbon monoxide. The effect of temperature on the yield of the synthesis was investigated. The synthesis process was monitored on-line in the temperature range 310-380°C, completely covering the maximum efficiency of the process. Online analysis of the process by FTIR spectroscopy gave information about products of both methylation of o-cresol and pyrolysis of methanol. The maximum 85% yield of desired 2,6-dimethylphenol with more than 85% conversion of o-cresol was achieved at 340°C, at 1:6 molar ratio of o-cresol:methanol

Published: September 2013

Abstract
Advanced silica/lignosulfonate composites were obtained using magnesium lignosulfonate and silica precipitated in a polar medium. For comparative purposes analogous synthesis was performed using commercial silica Aerosil®200. Lignosulfonates are waste products of paper industry and their application in new multifunctional materials is of great economic interest. The composites obtained were subjected to thorough characterization by determination of their physicochemical, dispersive-morphological and electrokinetic properties. Their particle size distribution was measured, SEM images were taken, FT-IR analysis and colorimetric study were made, thermal and electrokinetic stabilities and parameters of porous structure were also determined. The results can be of interest in further application studies

General systems theory and the operation of basins without an outlet: A methodological aspect
Authors: Major Maciej 
Published: September 2013

AbstractBasins without outlets, often with a small water body at the bottom, are a characteristic element of a postglacial landscape. Areas nourishing those small landforms belong to the passive part of catchments of hydrographic systems and determine the retentivity of entire drainage basins. The most suitable approach to adopt in research on those objects seems to be the theory of a geoecosystem, a universal methodological conception used in describing geographical regions at various scales. It allows the use of quantitative research methods, and hence parameterisation of their environment. Thus, the geoecosystems of basins without outlets can provide foundations of their dynamic classification.
The dynamics of macrophytes in a lake in an agricultural landscape
Authors: Sender Joanna 
Published: September 2013

AbstractMacrophytes are a group of aquatic organisms affected by constant changes. One of the main factors influencing the rate and direction of these changes is the way of basin management. The aim of this study was to determine the effect of changes in the management of a lake catchment area in an agricultural landscape on the qualitative and quantitative structure of macrophytes and assessment of the ecological status of the lake in question. The study was conducted in the years 1996, 1999 and 2011 in Lake Głębokie Uścimowskie. This lake is small (20.8 ha surface) and shallow (about 6 m depth). In the 1990s in Lake Głębokie Uścimowskie from 14 to 15 plant communities occurred, which occupied 2.9 ha of the lake. This represented only 14.1% of the lake. In 2011 there was a slight growth in the number of phytocenoses (16), and significant increase in the area of phytolittoral - 5.98 ha. In the 1990s the range of ESMI index values, allowed the lake to be categorized as one with poor ecological status, but already in 2011 after a similar analysis, the lake was ranked in the upper limits of moderate ecological status of lakes. One of the main reasons for the rise in the ecological status of Lake Głębokie Uścimowskie, determined on the basis of the macrophyte index, as well as for the slight decline in trophy, was probably a sewerage system built in 2006 in Głębokie village.

Published: September 2013

Superior cluneal nerve (SCN) entrapment neuropathy is a known cause of low back pain. Although surgical release at the entrapment point of the osteofibrous orifice is effective, intraoperative identification of the thin SCN in thick fat tissue and confirmation of sufficient decompression are difficult. Intraoperative indocyanine green video angiography (ICG-VA) is simple, clearly demonstrates the vascular flow dynamics, and provides real-time information on vascular patency and flow. The peripheral nerve is supplied from epineurial vessels around the nerve (vasa nervorum), and the authors now present the first ICG-VA documentation of the technique and usefulness of peripheral nerve neurolysis surgery to treat SCN entrapment neuropathy in 16 locally anesthetized patients. Clinical outcomes were assessed with the Roland-Morris Disability Questionnaire before surgery and at the latest follow-up after surgery.
Indocyanine green video angiography was useful for identifying the SCN in fat tissue. It showed that the SCN penetrated and was entrapped by the thoracolumbar fascia through the orifice just before crossing over the iliac crest in all patients. The SCN was decompressed by dissection of the fascia from the orifice. Indocyanine green video angiography visualized the SCN and its termination at the entrapment point. After sufficient decompression, the SCN was clearly visualized on ICG-VA images. Low back pain improved significantly, from a preoperative Roland-Morris Questionnaire score of 13.8 to a postoperative score of 1.3 at the last follow-up visit (p < 0.05). The authors suggest that ICG-VA is useful for the inspection of peripheral nerves such as the SCN and helps to identify the SCN and to confirm sufficient decompression at surgery for SCN entrapment.
Individualized surgical strategies for Rathke cleft cyst based on cyst location

Published: September 2013

Object
An assessment regarding both surgical approaches and the extent of resection for Rathke cleft cysts (RCCs) based on their locations has not been reported. The aim of this study was to report the results of a large series of surgically treated patients with RCCs and to evaluate the feasibility of individualized surgical strategies for different RCCs.

Methods
We retrospectively reviewed 87 cases involving patients with RCCs (16 intrasellar, 50 intra- and suprasellar, and 21 purely suprasellar lesions). Forty-nine patients were treated via a transsphenoidal (TS) approach, and 38 were treated via a transcranial (TC) approach (traditional craniotomy in 21 cases and supraorbital keyhole craniotomy in 17). The extent of resection was classified as gross-total resection (GTR) or subtotal resection (STR) of the cyst wall. Patients were thus divided into 3 groups according to the approach selected and the extent of resection: TS/STR (n = 49), TC/STR (n = 23), and TC/GTR (n = 15).

Results
Preoperative headaches, visual dysfunction, hypopituitarism, and diabetes insipidus (DI) resolved in 85%, 95%, 55%, and 65% of patients, respectively. These rates did not differ significantly among the 3 groups. Overall, complications occurred in 8% of patients in TS/STR group, 9% in TC/STR group, and 47% in TC/GTR group, respectively (p = 0.002). Cerebrospinal fluid (CSF) leakage (3%), new hypopituitarism (9%), and DI (6%) were observed after surgery. All CSF leaks occurred in the endonasal group, while the TC/GTR group showed a higher rate of postoperative hypopituitarism (p = 0.7 and p < 0.001, respectively). It should be particularly noted that preoperative hypopituitarism and DI returned to normal, respectively, in 100% and 83% of patients who underwent supraorbital surgery, and with the exception of 1 patient who had transient postoperative DI, there were no complications in patients treated with supraorbital surgery. Kaplan-Meier 3-year recurrence-free rates were 84%, 87%, and 86% in the TS/STR, TC/STR, and TC/GTR groups, respectively (p = 0.9).

Conclusions
It is reasonable to adopt individualized surgical strategies for RCCs based on cyst location. Gross-total resection does not appear to reduce the recurrence rate but increase the risk of postoperative complications. The endonasal approach seems more appropriate for primarily intrasellar RCCs, while the craniotomy is recommended for purely or mainly suprasellar cysts. The supraorbital route appears to be preferred over traditional craniotomy for its minimal invasiveness and favorable outcomes. The endoscopic technique is helpful for either endonasal or supraorbital surgery.
Civilian gunshot wounds to the atlantoaxial spine: a report of 10 cases treated using a multidisciplinary approach

Published: September 2013

Object
Gunshot wounds to the atlantoaxial spine are uncommon injuries and rarely require treatment, as a bullet traversing this segment often results in a fatal injury. Additionally, these injuries are typically biomechanically stable. The authors report a series of 10 patients with gunshot wounds involving the lateral mass and/or bodies of the atlantoaxial complex. Their care is discussed and conclusions are drawn from these cases to identify the optimal treatment for these injuries.

Methods
A retrospective review was conducted of patients presenting to the emergency rooms of 3 institutions with gunshot wounds involving the atlantoaxial spine. Mechanism of injury and neurological status were obtained, as was the extent of the osteoligamentous, vascular, and neurological injuries. Nonoperative and operative treatment, complications, and clinical and radiographic outcome were recorded. The data were then analyzed to determine the neurological and biomechanical prognosis of these injuries, the utility of the various diagnostic modalities in the acute management of the injuries, and the nature and effectiveness of the nonoperative and operative treatment modalities.

Results
Ten patients with gunshot wounds involving the lateral mass and/or bodies of the atlantoaxial complex were identified. All but 2 patients sustained a vertebral artery injury. Each patient was evaluated using cervical radiographs, CT scans, and vascular imaging, 8 in the form of digital subtraction angiography and 2 with high-resolution CT angiography. Uncomplicated patients were treated conservatively using cervical collar immobilization, local wound care, and antibiotics. One patient was treated using a halo for instability and 1 underwent posterior fusion following a posterolateral decompression for delayed myelopathy. One patient underwent transoral resection of a bullet fragment. One patient underwent embolization for a symptomatic arteriovenous fistula and a second patient underwent a neck exploration and a jugular vein ligation. None of the patients received anticoagulation therapy. The mean follow-up duration was 13 months. All but 2 patients regained their previous functional status and all ultimately attained a mechanically stable spine.

Conclusions
These 10 patients represent a rare form of cervical spine penetrating injury. Unilateral gunshot wounds to the atlantoaxial complex are usually stable and the need for acute surgical intervention is rare. Unilateral vertebral artery injury is well tolerated and any information provided by angiography does not alter the acute management of the patient. Vascular complications from gunshot wounds can be managed effectively by endovascular techniques.
Endoscopic transnasal odontoidectomy combined with posterior reduction to treat basilar invagination
Authors: Yu Yong , Hu Fan , Zhang Xiaobiao , Ge Junqi , Sun Chongjing 
Published: September 2013

Object
Transoral microscopic odontoidectomy has been accepted as a standard procedure to treat basilar invagination over the past several decades. In recent years the emergence of new technologies, including endoscopic odontoidectomy and posterior reduction, has presented a challenge to the traditional treatment algorithm. In this article, the authors describe 1 patient with basilar invagination who was successfully treated with endoscopic transnasal odontoidectomy combined with posterior reduction. The purpose of this report is to validate the effectiveness of this treatment algorithm in selected cases and describe several operative nuances and pearls based on the authors' experience.

Methods
One patient with basilar invagination caused by a congenital osseous malformation underwent endoscopic transnasal odontoidectomy combined with posterior reduction in a single operative setting. The purely endoscopic transnasal odontoidectomy was first conducted with the patient supine. The favorable anatomical reduction was then achieved through a posterior approach after the patient was moved prone.

Results
The patient was extubated after recovery from anesthesia and allowed oral food intake the next day. No complications were noted, and the patient was discharged 4 days after the operation. Postoperative imaging demonstrated excellent decompression of the anterior cervicomedullary junction pathology. The patient was followed up for 12 months and remarkable neurological recovery was observed.

Conclusions
The endoscopic transnasal odontoidectomy is a better minimally invasive approach for anterior decompression and can make the posterior reduction easier because the anterior resistant force is eliminated. The subsequent posterior reduction can make decompression of the ventral side of the cervicomedullary junction more effective because the C-2 vertebral body is pushed forward. A combination of these 2 approaches has the advantages of minimally invasive access and a faster patient recovery, and thus is a valid alternative in selected cases.
Left-right axial rotation within C1–2 after implant removal

Published: September 2013

Object
Surgical treatment of atlantoaxial injuries may be performed by a variety of surgical procedures, with each of these having its own specific advantages and disadvantages. To preserve the range of motion within the atlantoaxial joint after surgical treatment, posterior atlantoaxial screw fixation according to the method of Goel and Harms could be beneficial. This technique is not considered to fix the joint permanently if the screws are removed. However, this must not necessarily be true, especially if one notices that cervical joints have a tendency for rapid fusion after surgery.
The objective of this study was to analyze left-right axial rotation following implant removal, with the following research questions addressed: 1) is there a relevant rotational left-right mobility in C1–2; 2) is there a difference in mobility depending on sex; 3) is there a correlation of mobility to age; 4) is there a correlation of mobility to the “implant-in-body time”; and 5) is neck pain improved by this method of surgical treatment?

Methods
This is a retrospective study in 10 patients who had received atlantoaxial fixation according to the Harms method following atlantoaxial injury. These patients had undergone implant removal after a mean time of 128 days, followed by functional atlantoaxial CT in left-right rotation. Statistical analysis was performed using the SPSS software package; significance was assumed for p < 0.05.

Results
The following findings are reported. 1) Left-right axial rotation within the atlantoaxial joint was measured to be 17° (mean value) following implant removal. 2) There was no significant difference between men (20°) and women (14.8°) (p = 0.595). 3) Left-right axial rotation negatively correlated to the age of the patient (r = −0.646, p = 0.043). 4) “Implant-in-body time” did not influence left-right axial rotation (r = 0.04, p = 0.907) if the implants are removed within 90–180 days after surgery. 5) Neck pain as assessed by the patients themselves on the visual analog scale was 7.9 ± 1.1 preoperatively and 3.6 ± 1.2 (mean ± SD) after implant removal (p = 0.002).

Conclusions
The authors conclude that removal of the implants 3–6 months after posterior atlantoaxial fixation according to the method of Goel and Harms is beneficial for obtaining some axial rotation within the atlantoaxial joint. The range of motion preserved depends on the age of the patient.
