Dynamic Response Improvement of Crushed Rock With Cement Modification
Authors: Siripun Komsun  , Jitsangiam Peerapong  , Nikraz Hamid
Published: February 2025

This paper aims to report the deformation behavior improvement of cemented crushed rock as a road base material subjected to cyclic loads from repeated load triaxial (RLT) tests with a series of various stress paths in order to develop more understanding of modified road base material. As is well known, pavement surface rutting with unacceptable deformation is normally the main cause of damage in flexible pavements. Currently, existing and natural materials are unable to cope with the premature deterioration. Factors contributing to such damage are the excessive permanent and resilient deformation of a base layer including the behavior of a dynamic response of unbound granular materials (UGMs) under traffic loads is not well understood. The cement modification was utilized to enhance limited use of raw crushed rock subjected to different stress conditions. In this study, raw crushed rock was mixed with 2% cement content at particular 100% optimum moisture content (OMC) and 100 % maximum dry density (MDD) then was kept 7 days to reach selected hydration periods of cement content. Subsequently, the stocked mixture was retreated and re-mixed and was kept 28 days for curing. The retreating process is used to avoid micro-crack in the construction field that usually generate by stabilized procedure. Finally, compacted samples were subjected to RLT tests in order to simulate the actual condition of pavement. The study reports that modified crushed rock was enhanced the static and dynamic responses. Moreover, the effects of dynamic responses were investigated and the limit uses of using modified crushed rock in pavements were determined.

Published: February 2025

In this study, to evaluate the effect of the vaporization of dissolved gas in the pore water on the strength properties of sea-bottom shallow sediments obtained from deep seabed, core samplings were conducted in offshore Sakhalin Island, Sea of Okhotsk shallow gas hydrate province. Some kinds of on-board tests such as vane shear and cone penetration tests and physical properties tests such as water content, grain size distribution, specific gravity, plasticity tests were performed for the samples. These test results were compared to the concentration of dissolved gas in the pore water of the samples.
On the Argumentative Agent Types and Negotiation
Authors: Mbarki Mohamed  , Bentahar Jamal  , Moulin Bernard
Published: February 2025

We propose a framework for argumentation-basednegotiation where Agents' constraints such as budget and time play a key role in determining the set of offers agents can make. Each offer is supported by arguments and each agent tries to achieve an agreement using arguments to persuade the opponent to make concession. An agreement is achieved when the last offer is accepted. Two concession and two acceptance strategies are identified and their different combinations result in four types of negotiating agents. The paper discusses completeness, Pareto optimality, and Nash equilibrium results with respect to these types.
Biologically Inspired Turn Control for Autonomous Mobile Robots
Authors: Perez-Sala Xavier  , Angulo Cecilio  , Escalera Sergio
Published: February 2025

An exportable and robust system for turn control using only camera images is proposed for path execution in robot navigation. Robot motion information is extracted in the form of optical flow from SURF robust descriptors of consecutive frames in the image sequence. This information is used to compute the instantaneous rotation angle. Finally, control loop is closed correcting robot displacements when it is requested for a turn command. The proposed system has been successfully tested on the four-legged Sony Aibo robot.
EUCLIDES: A European Clinical Laboratory Data Exchange Standard (AIM-Project: A 1033)
Authors: De Moor Georges J.E.
Published: February 2025

The goal of the EUCLIDES project was to provide a European standard for clinical laboratory data exchange between independent and heterogeneous Medical Information Systems. EUCLIDES aims an open standard i.e. freely avialble to all, and unbiased towards any manufacturer's hardware or software. By convergence with other emerging standards, it could develop into a world standard. It could also be extended to other fields of medicine. EUCLIDES addresses the data exchange problem in a three-pronged approach : 1. the message transfer-mechanism, 2. the message syntax, and 3. the medical coding systems used within the message. Moreover, the EUCLIDES system offers through the EUCLIDES BRIDGE a user-friendly software solution for interfacing with existing local systems at both the sender's and receiver's ends.

The results, primarily in the form of a general framework for monitoring systems, are intended as a starting point for further work in this area.
TIME COURSE ACCURACY OF THE NON-INVASIVE BLOOD PRESSURE MEASUREMENTS IN THE ASSESSMENT OF THE NEURAL CONTROL OF THE CARDIOVASCULAR SYSTEM
Authors: Pinna Gianni  , La Rovere Maria Teresa  , Cesare Antonio Di  , Mortara Andrea
Published: February 2025

Time course of beat-by-beat error measurement associated with continuous non invasive monitoring of arterial blood pressure by the Finapres device, has been analyzed during short-term (up to 7 min) recordings either at rest (stationary conditions) or after phenylephrine injection (dynamic conditions) in 22 post-myocardial infarction patients. The equipment set point Self-Adjustment was deactivated during recordings. The systematic and random components of the error have been estimated over one min consecutive intervals for systolic and diastolic pressure. Long-term (> 20 min) reproducibility has been assessed as well. Quite a stable performance has been found during short-term stationary conditions associated to a high interpatients variability of systematic error and to a not negligible random error. A slight drift of systematic error, either for systolic or diastolic pressure, has been detected in long-term analysis. During dynamic conditions a significant difference in accuracy, between the first and second min after phenylephrine injection associated with a global loss of stability, has been observed during short term recordings consistent over the long-term period.

Since the early 1980’s educational services in Queensland, Australia have become decentralised. Many children with low vision who live in regional and remote areas do not receive equitable service. A project initiated in 1987, operating on a biennial basis, utilising local hospitals and educational resources, together with expertise from a paediatric low vision team based in the capital city of the state, has been effective in providing more equitable service throughout the state and assisted local support staff to identify children needing this service.
Why Should You Trust a Decision Support System?
Authors: Fox John  , Jackson-Smale Andrew
Published: February 2025

Almost two decades' experience in building expert systems has shown that strong development methodologies are desirable if we are to ensure that systems are effective. Logic programming techniques combined with software engineering methods offer a potent discipline for ensuring that software is sound. However, if we are to achieve trust in any medical technology it is not enough to demonstrate soundness. We must also show, so far as is possible, that it is safe. Alongside the pursuit of rigorous software development techniques, therefore, we need to investigate general design and development methods that minimise the occurrence of hazards. We can adopt some general techniques from existing safety engineering practices, but AI also supplies some important new ideas for improving safety.
Modelling Perspectives in Medical KBS Construction
Authors: Wielinga B.J.  , Schreiber A. Th.  , de Hoog R.
Published: February 2025

In addition to issues directly related to problem solving (expertise modelling, computational realisation), there are two areas which are critical for successful use of KBS technology in (medical) practice. The first area concerns the analysis of the organisation in which the KBS has to function and of the tasks in this organisation that can profit from KBS or other automated support. The second area concerns the analysis of the required interaction of a KBS with other agents, such as various types of users (expert and non-expert physicians, nurses, other health-care professionals) and other software systems. We argue that there is a need for a R&D effort towards a comprehensive methodology for medical KBS construction that covers all these areas. This ensures that KBS technology is applied for real-life problems and that users actually benefit from it. It also establishes clear routes for integrating KBS in a principled way with other medical information technology.

Published: February 2025

Autonomic abnormalities are an important component of the pathophysiology of patients with cardiac failure. Power spectral analysis of heart rate variability gives a noninvasive means to investigate this abnormality and a prognostic tool in the management of this syndrome. Further studies are, however, necessary to establish the reproducibility and physiological significance of the parameters estimated by this technique.
Overview of Published Assessment and Evaluation Studies
Authors: Van Der Loo Ruud. P.
Published: February 2025

Selected evaluation studies (n= 108) of automated information systems in the diffusion phase of their life cycle are classified according to the following features: type of automated information system, type of study design, type of effect measure, type of data collection methods and type of economic analysis. Results show that that certain types of automated information systems (i.e. auxiliary systems) have not much been evaluated. Furthermore for certain study designs (e.g. time series design), data collection methods (eg. modelling and simulation) and effect measures (eg. jobsatisfaction) it is observed that these are hardly used. The study demonstrates a relation between the type of automated information system and the effect measured. The evaluation of diagnostic systems is mostly aimed at process measures (e.g. the performance of the user), whereas for the evaluation of treatment systems with outcome measures (e.g. mortality, Qaly) are clearly preferred. The evaluation of nursing and supporting systems with mainly focusses on the effects on structure measures (e.g. time consumption of personnel). There seems to be a trend towards the use of weaker study designs, mainly for the evaluation of supporting systems and nursing systems. The performance of strong study designs does ofcourse not guarantee a high quality of the evaluation study. As the analysis shows most of the studies adressed less than 60% of attributes of a quality checklist, indicating that there is no reason to have great confidence in the results of the stronger designs. We were surprised to find only 6 studies out of 108 that carried out an economic analysis alongside a controlled clinical trial. Also the quality of the economic analysis performed reveals no great confidence.
Augmented Reality in the Treatment of Parkinson's Disease
Authors: Riess Tom  , Weghorst Suzanne
Published: February 2025

A primary symptom of Parkinson's Disease, akinesia, progressively restricts the ability to walk. Paradoxically, Parkinson's patients have little difficulty stepping over objects in their path, even when they are totally unable to initiate a step on open ground. Virtual reality technology provides a way to take advantage of this phenomenon to enable walking, by presenting virtual objects overlaid on the natural world. Normal stride length, and even running, can be enabled, provided the virtual cues are spaced properly and simulate the appearance of staying stable on the ground as the person moves. Other movement symptoms of Parkinson's and side effects of its pharmacological treatment have also been shown to be influenced by visual cues.

Authors: Netz V.
Published: February 2025

Chip cards used to store personal health data permit the fundamental human right to health and self-determination to be safeguarded much more effectively than it has ever been possible with conventional means. Chip cards make it easier for healthy or ill people to record their own health data; people are encouraged to lead a healthier life and provide an excellent data base for physicians, pharmacists or in cases of emergency. Moreover, a chip card can be used as a memory aid with signal function throughout a person’s life. The SANATURA Health Promotion Card is presented as an example as it is practicable in Germany today.

Authors: M. Sanvig Christensen  , Parker J.  , Ravndam J.
Published: February 2025

This paper describes the construction and use of a Test Center for quality assurance of electronic data transfer in primary health care. The Test Center was designed for evaluation of data communication between 5 different computer systems, used in private practice in Copenhagen, and the central laboratory, serving the primary sector physicians in this region. In EDIFACT structure data were transmitted and distributed through VANS to the relevant mailbox addresses. The Test Center was very useful for the success of transferring laboratory results to doctors in private practice. The Center was also used for evaluation of transfer of prescriptions from private practice to pharmacies. The utilization of a Test Center is strongly recommended before health care data transmission is implemented for routine use.
DIABTel: A Telemedicine Service for Diabetes Care
Authors: GóMez Enrique J.  , Hernando M. Elena  , del Pozo Francisco
Published: February 2025

This paper presents the DIABTel Telemedicine Service to support daily care of diabetic patients. The telemedicine system relies on three basic telemedicine services: telemonitoring, telecare, and teleeducation of patients. The system architecture is comprised by two main components: a Medical Workstation to be used by physicians at a hospital diabetes day center unit, and a Patient Unit, to be used during the patients daily living. The main features of the new approach to diabetes care provided by the DIABTel service are: 1) to provide both patients and doctors an integrated service to manage and improve several areas of daily diabetes care; 2) the continuous analysis of incoming patients monitoring data, based on the telemonitoring service 24-hour call center, providing patients with what we called a “supervised autonomy” during their ambulatory monitoring process; 3) the remote assistance of patients on treatment modification; 4) the decrease of the time response therapy adjustment, enhancing the patient’s self-management and education; 5) the improvement of the quality and quantity of patient’s monitoring data, facilitating the follow-up of an increased number of patients without decreasing their quality of care; and 6) the optimization of the number of patient’s visits to the hospital, but providing them, at the same time, a better access to clinical and monitoring data. A discussion of practical problems, limitations and critical implementation issues of the Telemedicine service are also presented.

Published: February 2025

Digital image archiving systems are used in medical departments usually in Local Area Networks (LAN). The connection of these LAN to Wide Area Networks (WAN) allow data exchange without any waste of time. This offers the opportunity of a distant expert consultation to another physician. In an ongoing pilot study the significance and acceptance of a long distance interpretation of endoscopic images by a second endoscopist is analyzed. After the examination the images are transferred to the second endoscopist using a high-speed network. His “second examination” report is then sent back to the first endoscopist. Communication software allows a discussion of both specialists about the images and the examination report. First results show a high degree of congruence between first and second opinion. The technical transmission causes no problems.

Tele-expertise: Users' and suppliers' liabilities
Authors: Allaert F.A.  , Dusserre L.
Published: February 2025

Telemedecine creates a new situation where two or more specialists decide on a diagnosis, together and at the same time but in different geographical locations. This paper deals with the respective liabilities and the professional status of the medical doctors involved in visual telediagnosis. From a legal point of view, it demonstrates, depending upon national legislation and deontological rules, that the practitioner directly in relation with the patient bears an entire liability. However he may ask guarantees from the expert or from the telemedecine system supplier if he thinks that these ones have a part in the responsibility, in case of litigation.
From Medical Information and Education Texts into Multimedia and Telematics
Authors: Caston Oscar L.
Published: February 2025

Four home electric appliances have become essential in the every day lives of most people in industrialised countries: the video tape player-recorder, the compact disk player, the fax machine and the personal computer. The fax machine, which was the only device that involved connecting with remote parties, became as common as any of the other three mentioned before, and is now essential to modern life. More recently, the Personal Computer (PC) was introduced to home environments, becoming a new common domestic appliance. Whereas in the early times the ‘PC to user’ symbiosis was associated with the idea of isolation and autonomy, in present times, modems, telematics and the Internet, have broken down that isolation. However, telematics are not only tools for business or serious activities: its "domestic" sprouting was stimulated by children and teenagers (computer game and Nintendo generations). Their interest makes their parents be more aware of the practical uses of the ‘PC via modem to Net’ resources, ... and not only for playing games and leisure activities.

Application of Fourier Transform Profilometry for Measurements of Human Back
Authors: Leonardi M.  , Cucek-Plenicar M.  , Lenarcic J.
Published: February 2025

A method is described for 3-D measurements of the human back in order to evaluate spinal deformities in scoliosis. The method uses Fourier Transform Profilometry to obtain the shape of the human back. First, a grating pattern is projected onto the object surface. The image is then Fourier transformed and processed. The method has many advantages over ordinary Moiré Topography. It has a higher sensitivity, it makes automatic distinction between depression and elevation from a contour map on the object, it is free from the effect of the reflectivity of the measured object. The method is also more appropriate for automated data processing. Some results of measurements on scoliotic patients are presented.
Biomechanical Simulations of a New Orthotic Approach for the Treatment of Scoliotic Deformities Based on Truncal Coupling Mechanisms
Authors: Aubin C.-É.  , Dansereau J.  , de Guise J.A.  , Labelle H.
Published: February 2025

A biomechanical model of the scoliotic spine and rib cage was used to investigate the hypothesis that there exist coupling mechanisms between the spine and rib cage (spinal motions that take place in other directions than the displacements of the rib cage subjected to orthotic loads) which may explain reported incomplete and non-optimal results obtained by brace treatments (flat back phenomenon, weak ‘derotation’, $\ldots$). Different forces were applied on the thorax, and it was found that the anterior loads applied on the rib hump were responsible for the reduction of sagittal curvatures, and they also contributed to increase the lateral shift of the spine and the frontal curvatures. Based on these results, a simple and more optimal approach to treat scoliotic deformities was proposed and consisted to apply loads laterally on the convex side and on the anterior thorax opposite to the rib hump, with a system that mechanically constraines the posterior rib hump to mode backward. Preliminary results on 4 patients showed that derotation of the trunk (up to 30%) and reduction of frontal curvatures (up to 4°) could be done without reducing physiological sagittal curvatures. More simulations on different scoliotic configurations are necessary to find the most optimal combination of forces to produce a real 3-D correction of scoliotic deformities.

Authors: Eurlings F.W.A.A.  , Goverde C.A.M.  , Van Gennip E.M.S.J.
Published: February 2025

The Telenurse project, financed by the European Union, aims to show the effectiveness of the application of the International Classification of Nursing Practice (ICNP) in practice. To this aim, the ICNP will be applied in three test sites in Europe. In the Netherlands, a pilot application of the ICNP is carried out at the VU Hospital in Amsterdam. The target of this pilot is to gain insight into the patient-related care activities of nurses, with the primary aim to provide the hospital management adequate information for managing nursing care. To this aim a subset of the ICNP is selected (the NMDS). The starting point is that data collection should not require an extra effort of nurses. The ICNP-based NMDS will therefore be collected by the nursing information system that is used by the hospital: the VISION system. VISION is a nursing information system which is integrated in the HISCOM Hospital Information System.

Published: February 2025

This paper describes a system that automatically classifies renal artery lesions from arteriograms in the context. of Percutaneous Transluminal Renal Angioplasty (PTRA). PTRA outcomes have been categorized into type A (success) or type B (failure) according to morphological features. The morphological features u'e naturally represented by fuzzy sets. The classification process is based on a fuzzy pattern matching procedure between fuzzy prototypes of lesions in the classes A and B and fuzzy quantified assessments of lesions in angiograms. The system provides a meaningful membership degree to the class rather than an abrupt yes or no answer. The system is expected to be a good framework to study the technical results of PTRA according to the anatomy of the lesion.

Published: February 2025

We created a self-study program using HTML browser on the Clinical Nursing General Remarks Course, Eighty-three students each selected a published book on a personal history (written personal reflections from individuals who had undergone medical treatment and hospitalization), read it and submitted reports of their impressions of the histories. Their reports were arranged from a nursing perspective and entered on the home page of our college using HTML browser. We intended that the students would become more interested in reading of the personal histories, and that they would acquire new self-study skills and increase their interest in Internet through use of our program. In addition, we hoped that this program would encourage positive communication and mutual sharing of information. The students were able to easily refer to a personal history according to their interest from a nursing perspective. Therefore this program realized the mutual learning among students and other users.

Published: February 2025

A clinical information system (CIS) prototype was created from an Object-Oriented (OO) design. We experienced considerable difficulties when implementing the OO data model in a relational database management system (RDBMS), including lack of semantic power and support for complex objects, inability to encapsulate object methods, and performance degradation due to extensive join operations. This paper reflects on the experiences of a CIS research project and explores issues related to the use of RDBMS and Object-Oriented Database Management Systems (OODBMS) in CIS design and development.

Published: February 2025

Arthroscopy has already become an irreplacable method in diagnostics. The arthroscope, with optics and light source, and the exploratory probe are inserted into the knee joint through two small incisions underneath the patella. Currently, the skills required for arthroscopy are taught through handson clinical experience. As arthroscopies became a more common procedure even in smaller hospitals, it became obvious that special training was necessary to guarantee qualification of the surgeons. On-the-job training proved to be insufficient.

The program can also be used for educational purposes.
Modelling Medical Decisions in DynaMoL: A New General Framework of Dynamic Decision Analysis
Authors: Leong Tze-Yun  , Cao Cungen
Published: February 2025

Dynamic decision analysis concerns decision problems in which both time and uncertainty are explicitly considered. We present a new dynamic decision analysis framework, called DynamoL, that supports graphical presentation of the decision factors in multiple perspectives. To alleviate the difficulty in assessing conditional probabilities over time in dynamic decision models, DynaMoL incorporates a Bayesian learning system to automatically learn the probabilistic parameters from large medical databases. We describe the DynaMoL modeling and learning architecture through a medical decision problem on the optimal follow-up schedule for patients after curative colorectal cancer surgery. We also show that the modeling experience and results indicate practical promise for the framework.
Consistency Management in Multiple Perspective Medical Decision Analysis

Multiple perspective reasoning is often involved in real-world decision analysis. Different perspectives may be suitable for different stages of the decision modeling process. Multiple perspective modeling calls for consistency management which ensures that the different perspectives reflect the same information. This paper summarizes the graphical perspectives currently supported in DynaMoL, a new framework for dynamic decision analysis. We introduce a new perspective, the tree view, into the framework. We present the main ideas involved in consistency management in the framework. We also discuss the critical issues involved in multiple perspective modeling of a simplified case study in medicine.

This paper describes a Web-based version of a protocol information system (ProtoVIEW) with which a wide range of diagnostic or therapeutic protocols can be retrieved and viewed. The Web-based version contains all functionalities of the non web-based version plus several new functionalities. The web version contains an X-ray viewer and a great deal of interactivity such as validation of electronic patient data forms. The most important additional function is the context sensitive protocol support which may lead to improved protocol adherence. Finally, the web-based version can be accessed from any working place since patient data and protocols are stored centrally.

The MAOUSSC (Model for Assistance in the Orientation of a User within Coding Systems) Web server supports a collaborative work on the description of medical procedures. The specifications for the MAOUSSC application are conceptual modeling, definition of semantically fully described procedures, re-use of an existing vocabulary, the UMLS, and sharability. This paper reports on some difficulties in applying those principles in a networked building and updating of the terminology. The users are physicians who have to represent procedure terms in the MAOUSSC formalism. They must apply the constraints of the underlying model, and re-use the representation of the UMLS knowledge base. In our experience, we found that the implementation of syntactic and semantic constraints was not sufficient. Guidelines for pragmatical aspects in representation are required to make a collaborative approach in terminology building more operational.

Published: February 2025

Efforts to build a telecommunications infrastructure that will link people nationally and internationally includes a focus on health care. A telecommunications infrastructure will add value to providers and consumers of health care only if they are able to use it to access and share information. Nurses often have information technology available to them, but are inadequately prepared to use it.
Fast Finite Element Modeling for Surgical Simulation

Given the geometric complexity of anatomical structures, realistic real-time deformation of graphical reconstructions is prohibitively computationally intensive. Instead, real-time deformation of virtual anatomy is roughly approximated through simpler methodologies. Since the graphical interpolations and simple spring models commonly used in these simulations are not based on the biomechanical properties of tissue structures, these “quick and dirty” methods typically do not accurately represent the complex deformations and force-feedback interactions that can take place during surgery. Finite element (FE) analysis is widely regarded as the most appropriate alternative to these methods. Extensive research has been directed toward applying the method to modeling a wide range of biological structures, and a few simple FE models have been incorporated into surgical simulations. However, because of the highly computational nature of the FE method, its direct application to real-time force-feedback and visualization of tissue deformation has not been practical for most simulations. This limitation is primarily due to the overabundance of information provided by the standard FE approaches. If the mathematics is optimized to yield only the information essential for the surgical task, computation time can be drastically reduced. Parallel computation and preprocessing of the model before the simulation begins can also reduce the size of the problem and greatly increase computation speed. Such methodologies are being developed in a combined effort between the Human Interface Technology Laboratory (HIT Lab) and the Mechanical Engineering Department of the University of Washington. We have created computer demonstrations which support real-time interaction with simple finite element soft tissue models. In collaboration with the Division of Dermatology, a real-time skin surgery simulator is being developed using these fast FE methods.

Published: February 2025

The University of Houston College of Optometry (UHCO) has developed a strong Telemedicine Optometry/Ophthalmology program. Patient care, clinical teaching and research benefit from utilizing Telemedicine technology. This initiative between Optometry and Ophthalmology is at the forefront of eyecare! Presented here: clinical teaching opportunities via tele-education including retinal, uveitic, neuro-ophthalmic disorders and glaucoma. Seminars introduce students to this technology and enhance their clinical experience through exposure to eye pathologies often related to systemic diseases. UHCO’s affiliated clinics include multidisciplinary centers staffed by optometrists: the Frost Eye Clinic (HIV multidisciplinary care), Good Neighbor Health Clinic and Rusk School Health Promotion Project (indigent multidisciplinary care). These centers can converse on line with eyecare professionals. Large sites interested in low vision/visual rehabilitation include: The Institute for Rehabilitation and Research (TIRR), the Social Security Hospital (Lima, Peru), the Matagorda General Hospital and the Quentin Mease Hospital. These sites, do offer quality care but require visual rehabilitation programs provided by UHCO. These sites also provide exposure to pathology for the students. A residency program trains optometrists in Telemedicine. The research program focuses on optics and imaging necessary to diagnose glaucoma, diabetic retinopathy, and neuro- ophthalmic disorders through Telemedicine. UHCO supports the advancement of standards in tele-eyecare.

Published: February 2025

Cooperation between Health Care Professionals is essential for the quality of care. Workflow systems could improve the transfer of informations and responsibilities within Health Care Actors. We have proposed a conversation-based Workflow in order to modelize the therapeutics plan in the ICU. In such a complex field, the flexibility of the workflow system is essential for the system to be usable. We have introduced some dynamicity by adding roles in the model. With the use of roles, the dynamicity of the workflow is assumed by the routing process. We need to use simulation to be able to study the impact of routing algorythms on the efficiency of the coordination.
Classification of metabolic patients using dynamic variables

Published: February 2025

The severity of metabolic syndrome is usually determined according to static variables (blood glucose, insulin level, body mass index etc.) The most important classification is dynamic and prognostic classification which can be used to determine the ability to decrease elevated metabolite and hormone levels or to lose weight. Different mathematical approaches were used to determine these phenomena : 1. Mathematical modelling e.g. (Bergman minimal model or glycation model). 2. Predictive calculations using multiple regression (using static and dynamic parameters to determine weight loss in obesity treatment). 3. One day starvation test (finding very variable hormone and metabolic changes in obese patients). We can conclude There are 3 types of metabolic parameters: A. Static (basic) description, B. Functional (actual) description, C. Dynamic- stability describing variables. Mathematical modelling is a complicated method needing many blood samples. It is very invasive for patients and it is difficult to be repeated. Predictive importance can have also repeated measured metabolic data which are able to classify the stability (fixation) of metabolic state. Some basic parameters and simple dynamic tests like one day starvation test can be used in prognostic classification of patients who are able to change their fixed metabolic state.
